REPORT NUMBER 07-00 Date: February 18, 2000 0 n 3 Subject: RouQe Park Neighbowhood Study Page 2 ORIGIN: Council authoriud stnff to initiete the Detailed Review of the Rouge Pnrk Neighbaurhood on Mny 17, 1999, Uuough Resolution #111/99, /:liyM:(�7:7��1'ii The Planntng Act, R.S.0.1990, chapter P.13 FINANCIAL IMPLICATIONS: No direct costs to the City are anticipated as a result of Council's adoption of the Rouge Purk Neighbourhood Development Guidelines and Environmental Master Servicing Plan. My commitment by the City toward pnriicipation and funding of n Rouge•Duffins Wildlife Corridor Manngement Plan will be subject to Council's consideration of a futurc report on the matter. EXECUTIVE SUMMARY: Pickering initiated a"detuiled revicw" of the Rouge Park Neighbourhood in ]une, 1999. The pu�pose of the study was to prepare a comprehensive pinn ta guide future development of the neighbourhood. The completcd study has resulted with two principnl documcnts - the Rouge Purk Neighbourhood Environmeninl Mnstcr Servicing Plan, nnd Rouge Purk Neighbourhood Dcvelopment Guidclines. The Environmentel Mnstcr Servicing Pian (scc Appcndix I to Report No. PD 07-00) refines the limils of dcvelopnble arcus of the ncighbourhood. It nlso providcs direction on cdge mnnngcment strategics rcquircd nlong boundarics betwecn devclopable and non•developablc arens to ensure thut new dcvelopmcnt maintains, and wherc nccessary, enhunces adjncent natuvl features and functions. The third componcnt is n stortnwater management strategy. Together these components establish a strategy for nntura! resource conservation and stormwater munagement within thc Rouge Park Neighbourhood. Stnff therefore recommend thnt Council adopt the Ro�ge Pazk Neighbourhood Environmental Master Servicing Plan. The Rouge Park Ncighbourhood Devclopment Guidelincs (see Appendix 11 to Report No. PD 07-00) estnblish urban design criteria, identify sites for nn elementary school and neighbourhood pazk, nnd identify major strcet connections. To establish a basis for thc prcpnrntion nnd review of dcvclopment epplications for lands within the neighbourhood, stnff recommend that Council adopt the Rouge Park Neighbourhood Development Guidclines. Completion of the neighbourhood study has provided a comprehensive understanding of tho aren, nnd its future requirements. This bcttcr Ievel of information can be used to rcvise certain designations and policies within the Pickering Official Plan, regarding such mauers as land use, urban design objectives, and transportation links, Some informational revisions, such as those to descriptive text and the Rouge Purk Neighbourhood Map, can be implemented through a Councii resolution. Accordingly, staf'f recommend that Council adopt "Infomiational Revision No. 7 to the Officinl Ptan", as set out in Appendix IV to Report No. PD 07-00, Official Plen nmcndmcnls ure required for the remaining revisions, therefore smff recommend thnt a Statutory Public Infortnation Meeting be held to discuss potential emendments to thc O�cinl Plun, es gcnernliy set out in Appendix V to Report No. PD 07-00. Statl'recommend thet Cauncil request the Region of Durhwn consider thc mdesignation of Pinch Avenue west of Altone Rood, and Townline Rosd south of Tnunton Road, from Type 'B' Arterial Roads to Type 'C' Arierial Roads, during preparntion of its recently initiatcd 7'ranspoctetion Masterplen Study. If the redesignations ure determined to bc appropriatc, Uic resultant lowerin$ of road stetus would ossist in shiRing their roles ns conduits for commutcr ;rnffic to thnt of e neighbourhood focus, while reducing the potentint for ncgutive impncts on the natural environtnent. � � � REPORT NUMBER 07-00 Subject: Rouge Park Neighbawhood Study Dute: February 1 S, 200p Page 3 Additionally, to essist with the on-going health of thc Rouge-Duffins Wildlife Corridor, swff I recommend that Council request the Ministry of Netural Resources and other appropriate agencies/partners, preparc a"Rouge•Duffins Wildlifc Corridor Manegement Plan", and establish funding for the maintennnce and restoration of thc Cortidor. Stafi' also recommend that Council request the Ontario Renity Co�poration iransfcr all non-developable propenies within the Rouge Pnrk Neighbourhood to a public authority having a conservation mandate. BACKGROUND: 1.0 Studv Overview 1.1 Neighbourhood Descriptian The Rouge Park Neighbourhood is located nlong thc west side of Pickering, at the northem limit of the City's South Urbnn Area. It comprises an arca of about 160 hectnres. The neighbourhood is bounded on the west by the Pickering-Toronto boundary, on the north by the interprovincial Pipeline/C. P. Rail linc, on the south by ihe Ontario Hydro Gntineau Corridor, and on the csut by open space lands just east of Rosebank Roud (see Location Mup, Attachment #1). Curmnt land usc in the neighbourhood cnn bc chnractcrized ns primarily pre-1970's scattered residential, with n fortncr reslnurnnt use at the south-eust corncr of Altona Roud nnd Finch Avenuc. Lnnds within thc ncighbourhood contnin numerous smnll psucels in privnte ownership, interspersed with somewhat larger blocks of Innd hcld under provincial ownership. Thc curmnt populntion of thc neighbourhood is approximotely 200 peoplc. 1.2 Pickering Officinl Plan Until 1997, Innds in thc Rouge Pnrk Neighbourhood werc located outside of thc City's Urbnn Area. With the approvul of the new Pickering Official Plan in October, 1997, Innd use designations wcrc cstablished for thc ncighbourhood. Thc Innds nre primarily designatcd as "Urban Rcsidential Arcn - Low Density" and "Opcn Spacc System - Natural Arcu". The Ontnrio Hydro cortidor Innds nre designated "Freewuys und Major Utilities - Potential Multi-Use Arcn", and the south-east comer of Finch Avenue nnd Altona Roud is designnted "Mixed Usc Aren - Locul Node", which permits a range of residentiel, retnil, commercial, and institutional uses. Thc Official Plnn populntion tnrget fnr the ncighbourhood is 1,600 people by the year 2016. Following the Region of Durham's approval of the new Pickering Oflicial Plan, sevcrul appeels were made to the Ontazio Municipal Baard (OMB), two of which nffected this nrca. Appenl A1 was initiated by the Ministry of Municipa! Ati'airs, and dealt with the Officinl Plan's designation and policies related to the Rouge-Du1Tns Wildlifc Corridor. Appeul A2 wns initiated by a privute pnrty, und pertained to the "Open Space System - Na!urel Area" designadon of lands ulong the north boundury of the ncighbourhood. Through a series of OMB mediation sessions, the parties and pariicipnnts involved in the two appeals resolved their issues, and reached a settlement. Central to the settlement was nn agreement that the Rouge-DuTns Wildlife Corridor would coincide with lands designated "Open Space System - Natural Area", as well as "Freewnys nnd Major Utilities - Potentinl Multi-Use Area". This settlement was npproved by the OMB in April, 1999. However, the two nppeuls remain unresolved for tha north-cnst comcr of n property known ns the Benre Estate/Mup Renity Property, locnted on thc notth side of Finch Avenue, opposite Woodview Avenue (refcr to Attachment H2 — sce section 3.3 of this Report for additional dctnils). REPORT NUMBER 07•00 Datc: Febcuary 18, 2000 0 n) Subject: Rouge Pazk Neiyhbourhood Study Pagc 4 1•3 Purpose of thc Neighbourhood Study Although the new Official Plan establishes urban land use designetions for the naighbourhood, it requires the underteking of a"Detailed Review" prior to pertnitting major development. The purpose of undertaking the review is to establish end elaboratc upon a"vision" for the neighbourhood, which will guide future development. In June, 1999, engineering and environmental consultnnts were retained by the City to assist staff with the study. The principal tasks of the review included: • identify end assess the natural features end functions of the area, nnd develop strategies to maintnin/enhance these features; • refine the mix, aRangement, scale and intensity of land uses, including the siting of municipnl parks and school sites; • identify a future collector road pattem; • identify design objectives for the relationship between new developmcnt and public streets, und identify udditional specific design sUategies for the neighbourhood which articulate un "urban village" chsuacter at the intersection of Altona Road and Finch Avenue; end • idenlify the proposed wnter, stormwatcr management �nd snnitary servicing schemes. 1.4 Background Reports During the Full and cariy Winter of 1999, two mnjor reports were produced. The Rougc Peck Neighbourhood Study - Phase I Report wns releused on October 7, 1999 (copies of the Report sue nvnilable from thc Planning and Dcvclopment Departmcnt). The Report includes: an assessmcnt of significant nnturnl nnd man-mnde fentures that currently exist in the neighbourhood; a discussion on infraswcture rcquired to support new dcvelopment; urbun dcsign objectivcs; and, n serics of neighbourhood development concepts that display various means of accommodnting the dircction cswblished by thc first threc sections of thc Phnse i Repart The Phase 2 Report of the Rouge Park Neighbourhood Study (relensed on December 10, 1999), continues from thc infortnation, conccpts and strategics discussed in the Phase I Rcport, The Phnse 2 Report (also ovnilable from the Pinnning ond Development Department) is divided iato five parts, which include: an account of all written comments received on the Phase 1 Repart; a singlc, refined neighbourhood development concept; a drafi Environmental Master Servicing Plan; draR Development Guidelines; nnd, an identification of amendments nnd informationnl revisions to the OfTcial Plnn that may be requircd to implement the recommendntions of this study, as well as other matters worthy of further discussion. The Phase 2 Report hns served as the background document for thc prcparation of thc recommended Rouge Park Neighbourhood Development Guidelines nnd Environmcnml Mnster Servicing Plan. Staff recommend that both reporls be received as background infarmation. 1.5 Public end Agency Consultation Consulting with residents nnd landowners within nnd nround the Rouge Park Neighbourhood, as well es technical agencies end iNerested others, hns been nn integml component of this study. The time and effort tnken by all wha hnve contributcd is grently appreciated. 1.5.1 Rauge Pazk Neighbourhood Study Advisory Commitlee • M advisory committee was established lo provide key stalccholders with n fonun for discussion during the progress of the study. A list of thc advisory committec membcrs is included es Attachmcnt H3. O n� 1tEpORT NUMBER 07-00 Date; Februaiy 18, 2000 Subject; Rouge Pazk Neighbourhood Study Page 5 1.5.2 Notice of Meetings With respect to genernl public consulmtion, circulation lists include nll landowners within the study area and within l20 meves of the study area, tenants within the study area, Pickering ratepayer associations, and any others who requested noticc. The agcncy circuladon list includes the Region of Durham, adjacent municipalities, Toronto and Region Conservation Authority, Ontario Hydro Services Campany Inc., Ontario Realty Coiporation, Rouge Pazk Alliance, and both Durham school boazds, The consultation program included four formal public meetings: • introductory Public Information Session hcld August 25, 1999, to discuss the purpose of the study; • Public Meeting held October 14, 1999, to discuss the background information, servicing and design strategies discussed in the Phase 1 Report; • a workshop held November 23, 1999, for landowners snd residents within the neighbourhood to "brainstortn" and discuss neighbourhood design issues; and • Public Meeting held December 14, 1999, to discuss the components of the Phase 2 Report. In addition to written noticc of thcse mectings, newspaper udvertisements were also pluced. Additionnlly, all landowners nnd tenants within the study area received a summnry of the Phasc 2 Rcport and a copy of notcs tnken during the Dccember 14'� public mceting. 1.53 Commenis Received A summnry of nll written comments on the Phase 1 Rcport was included as a table within the Phase 2 Report. All written comments submided rcgnrding the Phnse 2 Report nrc incluc;ed ns Appcndix V to Report No. 07•00. Notes taken during the December 14, 1999, public meeting are nlso included within Appendix V. All pubiic and agency comments wero considercd in the prepurntion of the recommended Development Guidclines and the Environmentul bfastcr Servicing Plan. 2.0 Discussion 2.1 Environmental Muster Servicing Plan (EMSP, see Appendix I of Rcport No. 07-00) The consulting firms of XCG Consultants Ltd. and ESG Intemational were rctained by the City to prepare the EnvironmenWl Master Servicing Plan for the Rouge Pnrk Neighbourhood. Their understnnding oF engineering end environmenml matters rclated to the neighbourhood has been of great ussistnnce tivoughout this study, nnd stnfT ure apprcciative of their efTorts. 2.1.1 Components of the Recommended Environmentnl Master Servicing Plan The rccommended Environmental Master Servicing Plen provides direction on thrcc key nspects of development in the neighbourhood, as follows. (a) Refrnemen� oj,Developmen� Llmtls Schcdule I of the Official Plan identifies lnnd use des�gnations. One of lhe first tnsks of the consulwnts was to better define thc boundnries between "devclopnble" and "non-developable" nreas within the neighbourhood. Upon cxaminotion of existing information, air photo interpretation and field rcconnaissance, devclopable umas were rofined, based on thc following principnls: • refercnce to the OMB-approved resolution to Appenls Al nnd A2 (sce section 1.2 of this Rcport); thc Bonrd's dccision includcs Minutcs of Sctticment, which REPORT NiJMBER 07-00 Date: February 18, 2000 0 n 7 SubjecC Ruugc Park Neighbourhood Study Page 6 identify certain lends as being developablc (the discussion focuses on lands on the north side of Finch Avenue, east of Altone Road, and a pocket of land on the west side of Woodvicw Avenuc, south of Finch Avenue); • exclusion of lands identified within thc revised wetiand baundary for thc Townline Provincially Significant Wetland Complex; • axclusion of valley and stream corridors; • exclusion of upland wooded habitet contiguous to wetlands and valleylands; • exclusion of key lands providing/augmenting habitat linkages; and • exclus: �n of areas where development would have significant negative impacts on features and functions of the Rouge-Duffins Wildlife Corridor. As mentioned in section 1.2 of this Report, Official Plun designutions for the north-east portion of the Beare Estute/Mnp Renity propedy remain undcr appcal. The cstablishment of development limits for this property will occur tluough revicw of its relnted development applications, or a future OMB hearing, if necessary. (b) Edge Management S�ra�egtes Following the refinement of developnble urcas, thc EMSP explains thnt whcrc devclopment occurs adjacent to natuml habitats, there is a need to manage the interfacc betwecn natural and developed arens. The purpose ofthis is to ensure that impacts of new development on adjacent naturnl fcatures and functions azc minimiud. The EMSP identifies the various edge types that exist in the neighbourhoc,d, und lists mechenisms that can addrcss the edge (bufters, setbucks, fencing, restorntion, etc.). lnitinlly, it was hopcd thnt completion of the EMSP would providc specific edgc mnnngcmcnt strntegics for all arcus within thc ncighbourhood, thus climinnting the future necd for site-specific Environmcnml Rcports. Howevcr, after gaining a better nppreciation for thc arcu's brond vnricty nnd intcrtclutcd naturc of its natural features nnd functions, und reulimtion that a specific cdgc munagcmcnt must rclatc to the specifics of a detailed devclopment proposal, it is apparcnt that a scoped Environmenml Rcport will bc rcquircd. Accordingly, the EMSP providcs directian on the type of cdae munagement most likely requircd for u specific cdge type, and identifics any further assessmcnt thnt is required. Environmental Reports will bc rcquired for individunl devclopmcnt proponents; they must be approved by the City, in consulwtion with conservution authorities. (c) S�ormwa�er Management Srraregles The final component of the EMSP is a stormwater manngcment svatcgy for the neighbourhood. The strategy includes two preferted locations for stormwater ponds within the Ontario Hydro corridor: one located near Woodview Avenue, and the other near Altona Road (see Figurc 7.4 of Appendix I). The two ponds nrc to be designed as "queliry" ponds (artificial wetlends), and have been sized to uddmss downstreum erosion concems. The Report provides a"pinnning" level of detnil for the pond sizcs and geneml locations. Responsibility for prccise siting of the ponds, detailed enginecring, and construction of the works will be cost-sharcd among dcvelopers within thc neighbourhood. Ontnrio Hydro has agreed to thc use of thcir corridor Innds, subject to the revicw of detailed plens. 2.1.2 Revi�ions to the DrnR Environmentnl Moster Servicing Plnn The provious section summarius thc contcnts of thc Recommcnded EMSP. A drnR of the EMSP wes included with the Phasc 2 Report, which was rcicascd for public comment o�s REPORT A:iIMBER 07-00 Date: February 18, 2000 Subjxt: Rouge Park Neighbourhood Study Page 7 on December 10, 1999. Following a rcview by staff und consultants uf the commcnts rcceived, ihe tollowing revisions werc incorporated into Ihe recommcnded GMSP: • a rcviud discussion on 1he role of wildlifc corriJors; • an updated list of rcquircments thnt nn Environmentnl Report will nddrcss for various developable areas within the neighbourhood; • revised edge management strutegics for lends adjucent to the Peuicoat Crcek; • a rcvised discussion on lend stewnrdship and the ownership of bufi'crs; • revised locations for the sturtnwater manngement ponds; • revised stortnwater cnlculations; • a list of secondury "best mnnagoment practices" that if incorpomteJ µiih future development, could reduce the rcquired size of stortnwater management pond:; • inclusion of an implementation section thut identifies a rccommcnded �iming of works, conswction phasing, nnd costs; • revisions to various meps nnd figures; and • scvcral editorial revisions and tcchnical clnrificntions. 2.1.3 Conclusions on the Recammended Environmental Master Scrvicing Plan The consultants' finul rcport provides a stmtcgy for natural rcsource conservntion and stortnwatcr management within thc Rouge Pnrk Ncighbourhood. It will nssist with the review of devclopment npplications, and also providcs dircction for the prcparation of development proposals. Accordingly, stafTrccommend thnt Council endorsc the "Rougc Purk Ncighbourhood Gnvironmental Mu�tcr Scrvicing Plan", nttachcd as Appcndix 1 to Rcport No. PD 07-00, ns the City's prcferrcd �trntcgy for nawml rcsource conscrvution nnd stortnwatcr managcmcN µithin thc Rougc Park Ncighbourhood. 2,2 Devclopmcnt Guidclines (sce Appendix II of Rcport No. PD 07•00) Developable nreas wi►hin the Rouge Park Ncighbourhoocf comprise many small propertics, somc of which arc irrcgulnrly shnpcd. Thc chnllcngc facing ncw dcvclopmcnt is ovcrcoming this fragmcnted owncrship, so that thc rcsulting impression is thut of u cohcsivc, well-dcsigncd ncighbourhood. In order to nchicvc this, thc Rougc Pnrk Ncighbourhood Developmcnt Guidelines provide Council, sinff nnd proponcnts with a comprchcnsivc basis for th: prcparation and rcvicw of dcvclopmcnt applicntions. 2.2.1 Components of thc Recommcnded Devclopment Guidclincs The following highlights the key sections of the rccommendcd Rouge Pnrk NeighbourhooJ Devclopmcnt Guidelines: (a) Servlcing The Development Guidelines identify the two prcCerred locations for stormwnter menagement ponds recommended by the Eh1SP (see scction 2.1 of this Report). The Region of Durham has confirtned that water supply is adcquutc in this ncighbourhood for the level of development envisioned by the Devclopment Guidelines. W�th respect to snnitary servicing, capaciry exisu in snnilnry sewcrs to the south thnt will accommodnte approximately 500 peoplc H�est of Petticout Cnrk, nnd 1,700 people east of the creek. Minor improvcments to ench scwcr will bc rcquircd prior to development. An altemate means of providing snnitary sewcrnge to certuin amus (particularly those on Ihc north sidc of Finch Avenue, wcst of Petticont Crcek) is u direct connection to the Yark-Durham Trunk Sewcr via n pumping stntion/fomcmuin. The Developmenl GuiJelines providc support for this type of servicing ntrangement, provided thut the pumping stntion/forccmnin is privntely owned and op�ratcd, or othcrwisc agrced to by the Region of Durham. REPORT NUMBER 07-00 Subject: Rouge Pazk Neighbourhood Study (bJ Populalion Targels Datc: February 18, 2000 � n 3 Page 8 The Official Plan establishes a population target for the Rouge Pnrk Neighbourhood of 1,600 people. Based solely on sanilary sewe± .apacity, a population target of 2,200 people is achievable (500 west of Petticoat Creek, and 1,700 cast of the creck). However, if the population were to grow much beyond 1,600 people, the Durham District School Board has indicated that an elementary school site would be required within the neighbourhood. In order to minimiu the need for public facilities in this area of limited developable landa, the Development Guidelines retain a population target of 1,600 people, with a meximum of 500 people on Innds developcd west of Petticoat Creek. The Guidelines explain the population uvget muy bc excceded if lhe City, in consultation with the Durham District School Bonrd, is satisfied thnt existing development, or proposed development, docs not genemte the need for ndditiona! school facilitics within the neighbourhood (which would be in nddition to the site required by thc Durhem Cntholic District School Bonrd). The populution terget of 500 people west of Petticoat Creek mny bc exceeded if the City nnd Region nre sutisfied that nitemative scrvicing nrrangcments nre fensible and nppropriute (see scction 2.2.1(n) ofthis Report). (c) Transpar�a!!on The Tertiary Plan of the Dcvelopment Guidclines establishes the genernl locntion of future principal ronds, ns �vcll ns potential ncccss locations to Finch �venue and Altonn Roud. These locations havc bcci rcvicwcd by Regionnl Works Depnrtment staff, and nre ucceptable. Thc precisc oricntation und numbcr of futurc roads will bc considered ttuough the rcvicw of dcvelopment applicutions. (d) Nelgh6ourhood Cenlre Developmcnt eround the intersection of Finch Avcnue und Altona Road will be the "hcart" of the neighbourhood, both in appearance and function. The use of epproprinte building heights, massing, architecturel features and Inndscnping will esmblish a focnl point nt this intersection. The south-east comer of the intersection is designatcd "Mixed Use Area - Local Node" in the Official Plan. This designation provides for u broad rnnge of uses, including: medium density residential; retniling of goods and services; otiices; resteurants; und community, cultural and recreutional uses. Thc mix of uses permitted by the Local Node designation fiuiher enhances opportunities for the Finch/Altona intersection to be thc focus of the neighbourhood, by providing for the day-to-day shopping needs of aren residents. Redevelopment of this comcr is strongly encouraged to accommodate a range of uses, in particular, rctail, commercial and office space on the first few tloors, with residential units on upper floors. The Guidelines expinin that retail focilities within the Neighbourhood Ccntre should provide for the day-to-day shopping needs of residents in the areu. Thereforc, "highwuy-commerciel" type uses such as gas stntions and drivc-through restawunts will not be pertnitted. (e) Pub!!c Facl/!tles A neighbourhood purk and cicmentnry school site ore locutcd nt the north-wcst corner of Finch Avenue and Altonn Rond. The Durhnnt Calholic Disvict School Board and the City's Director, Opcmttons and Emcrgency Scrvices have indicated the s(tes arc acccptable. Thc Catholic Bonrd ndviscs thcre is nn immediate nccd for O 1 O�pORT NUMBER 07-00 Datc: February 18, 2000 Subject: Rouge Pazk Neighbourhood Study Page 9 its school, and nnticipates its construction within the next f.:w years (subject w land acquisiGon). (n Denslry Tran.sfers and Bomues Sections 15.17 and 15.8 of the Oliicial Plen pertnit density bonuses and transfers, at the discretion of Council. Thc Development Guidelines esmblish the parametcrs in which the trunsfedbonus may accur. A density transfer mey occur if both the grunting nnd receiving properties demonstrate that the transfer will satisfy the requirements of the Guidelines. [f approved, an implementing zoning by-law will detail the granting and receiving properties, and the number of units trunsferred. A density bonus (up to 25% beyond thnt pennilted by the Officinl Plan), is given only in retum for the provision of specific services or facilities listed in the O�cial Pian, such as: additional open space; community facilities; ussisted or special needs housing; preservation of herimge buildings or structures; or, the preservation of natural herimge fcatures and fwctions. The Dcvelopment Guidclincs provide a list of scrvices or facilitics that may wurtant bonuses if thcy are provided through development in tl�c Rouge Pnrk Neighbourhood. The list includcs the provision of land for trnils, the provision of afl'ordable housing, and thc conswction of playgrounds. 2.2.1 Revisions to the Druft Dcvelopment Guideiines Thc previous section summnrizes thc contcnts of the rccommcnded Development Guidelines. A draR of thc Guidelines was includcd wilh thc Phnse 2 Report, which was relensed for public comment on Dccembcr 10, 1999. Fallowing stnffs review of the comments rcccived, thc following rcvisions wcre incorporated into the recommended Guidelines: • udditionnl discussion on the importance of existing nnd ncw strcets being designed in a mnnner thnt presents a distinct, cohesive character for thc neighbourhaod; • a revision to the strcetscape discussion such thnt a high level strectscapc design apply to Finch Avcnue and Altonu Rond; • additional discussion on building hcights for lands outsidc of thc Neighbourhood Centrc; • additional discussion on access locations, screcning, end restriction on commerciul uses; • additional diuussion on the circumstnnccs under which density trnnsfers and bonuses may be permitted; • minor revisions to the Tertiary Plan; and • several editorial revisions and technicul clarifications. 2.2.2 Conclusions on the Recommended Development Guidelines The Rouge Park Neighbourhood Development Guidelines will provide direction for future development within the neighbourhood. As with the EMSP, the Guidelines will assist with the review of development applications, and provide direction for the preparation of development proposnls. Accordingly, staff rccommend that Cowcil adopt the "Rouge Park Neighbourhood Develapment Guidelines", atwched as Appendix Il to Report PD 07•00, as thc City's preferted appronch for urbnn design, major strcet layout, and public facility siting within the neighbourhood. 23 Informational Revisions to the Pickering Officiel Plan Chapter 11 —"Urban Neighbourhoods" oF the Official Plnn, includes ncighbourhood policies specific to each neighbourhood. The policies are prcceded by introductory lext thnt describes thc ncighbourhood, and n nclghbourhood map that identifies such items as REPORT NUMBER 07-00 Date: February 18, 2000� � 1 Subject: Rouge Park Neighbourhood Study Page 10 future schools, parks and road connections. Revisions to thc introducwry text and neighbourhood map can be made by Council without a fortnal amendment of the Plen. With the adoption of the Rouge Perk Neighbourhood Development Guidelines and EMSP, the neighbourhood's introductary text and map will require rcvisions in order to identify: • that a detailed review has been completed, end Development Guidelines have been adopted by Council; • the location of u proposed elementary school and proposed ncighbourhood perk site; • a"proposed new road connection" illustrated ns a crescent on the west sidc of Woodvietv Avenue; and • a"proposed new roud connection" running from Finch Avenue to Rosebank Road. Steff recommend that Council adopt "Informationnl Revision No. 7 to the Officinl Plan" as set out in Appendix 111 to Report No. PD 07•00. 2.4 Official Plan Amendmenu One of thc bencfits of undertuking a comprchensivc study of this nnture, is thet it provides n dctniled level of information requircd by Council to make more detailed decisions (such as decisions on developmcnt applications). This infarmntion can be used to revise certain uspects of the OfTicinl Plnn. For exumple, a substantial amount of field work wns requircd for the EMSP — this has providcd enough information to rcfinc the Official Plan's Innd use und rcsourcc manngcmcnt schcdulcs. Othcr work, including prcpnrntion of the Dcvclopment Guidelincs, hus aiso providcd informntion thnt cnn refine O�ciul Plan policics. Appendix IV to RepoA No. PD 07-00 identifies scveml potentinl umcndmenls to the Official Plan. Thc following is nn ovcrvicw of thc proposed revisions. (a) Sched�Je 1— Land Use Srrucrure Certain lunds would bc rcdesignnted such that boundnrics between "Open Space - Nnturul Arca", and "Urban Residcntial Areu - Low Density", better rcflect the limits of dcvelopable nrcns, as dctertnined through the EMSP, nnd thc Minutes o1' Settlement for Appcnls Al and A2 to thc Pickering Official Plon. (b) Schedule ///— Resource Managemenl Certuin lends would be redesignated such thnt: • the boundary of the "Rouge•Duffins Wildlife Comdor' reflects Uie updated boundaries of the "Open Spoce — Natural Area" designntion on Schedule 1; and • the boundary of the provincially significant wetland "Townline Rand Swamp Complex" retlects the OMB decision rcgarding Appenl A1 and A2, as well ns revised mapping of the wetland recently updnted by the Ministry of Naturul Resources, (c) Sec!!on ll. /6 — Rouge Park Neighbourhood Paltcles Delete the current provision requiring the completion of Devclopment Guidclines prior to pertnitting mejor development within the uren. Add additionel policies ta • providc direction on tho implementation of density transfers nnd bonuscs; • identify thc relationship betwecn permission for cxceeding population targcts, end school board requircmcnts; Ol2 REPORT NIJMBER 07•00 Datc: February 18, 2000 Subject: Rougc Park Neighbourhood Study Page I 1 • prohibit highway-commercial type uses et the intersection of Finch Avenue and Altone Road (ges slations, drive-ilvough rcstnuran4s, etc.); • identify a locat road connection between Finch Avenue and Rosebank Road; • support ;he elimination of the Rosebank Road' jog" at Finch Avenue; • encourege the transfer of non-developable provincial lends to an appropriate conservation agency; and • provide direction on thc scale and types of uses pertnitted in the Local Nodc designadon at ihe south-east comer of Finch Avenue and Altona Road. (d) Seclion /0.17— Rougu-Du�ns W!ldlife Corrtdor PoHctes Add additional policies to: limit the range of pertnitted uses for lands designated "Freeway nnd Major Utilities • Potential Multi-Use Area" (the hydro corridor); and encourage the preparation of a Rouge-Duflins Wildlife Corridor Management Plan, and the establishment of funding for thc on-going maintenance and restorntion of the Corridor (see section 3.1 of this Report). 2.4.1 Statutory Public Informntion Meeting All amendmenis to the Official Plan will require n public consulintion process separate from this study, including o Stntutory Public Infortnntian Mceting. Accordingly, it is recommended thut Council direct stnff to hold a Stututory Public Infortnation Meeting to discuss potential amcndments to the Pickering Official Plnn rcquircd to implement thc recommendations of the Rouge Park Neighbourhood Study, as gencrally set out in Appendix IV to Report No. PD 07•00. 3.0 Other Mnttcrs 3.1 Downgrading of Finch Avcnue and Townlinc Road One of the principal goals af the Rouge Park Neighbourhood Development Guidelines is that Finch Avenue will continuc its role as the "backbone" of the neighbourhood. Finch Avenue is designated as a Typc 'B' Arterial Road in the Durham end Pickering O�cial Plens. Such e designation anticipates a specific rond function and design that will accommodate significant traffic volumes und speed. Ovcr time, this road functiom m�y fnuuate efforts in establishing a proper rclationship between the strcet and new devclopment, as wcll as pluce added suess on thc aren's natural features and functions. Finch Avenue west of Altona Road is owned by thc City. If the classification of this portion of the road is "rcduced" to a Type 'C' Arteriel, the lesscr dcsignation would result with less stringent acccss rcsUictions, right-of-way rcquirements and other design parameters. This will essist in shifiing Finch Avenue trom its role as a conduit for commuter traftic to thal of a neighbourhood focus, and reduce the potential for impacu on the natural environment. Townline Road is elso designated es a Type `B' Arterial Road, and it is a component of the same Regional road network. If Finch Avenue is reclnssified es a Type'C' Arierinl, it may also be appropriate to redesignate Townline Road (at Ieast the portion south of Tnunton Road) as a Type'C', for the same reasons discussed above. Both roads were designated es Type 'C' Arterial roads in thc Council•ndopted Official Plen, but were modified to Type 'B' Roads by the Region of Durham in its approvel of the Pickering Plen. • This is en opportune time to rcconsider theu designations, ns ihe Region hns initieted a"Transportation Masterplan Study" to revicw its n�ad nenvork and undettske an assessment of future needs, The Region's study provides an opportunity to review the future role of Finch Avenuc and Townline Rond within that road network, and within the context of an emerging urban neighbourhoad. REPORT N[JMBER 07-00 Date: Febniery I8, 200� � 3 Subject; Rouge Pazk Neighbourhood Study Page 12 Staff mommend that Council request thc Region of Durham consider the redesignation of Finch Avenue west of Altona Road, and Townline Road south of Taunton Road, from Type `B' Arteria! Roads to Type `C' Arterial Roads, durin� preparation of the Rcgion of Durhem Transportation Masterplan Study. ]f the redesignations arc determined w Ix appropriate, amendments to the Pickering end Durhnm OfTicial Plans wili bc required. 3.2 Rouge-Duffins Wildlifc Corridor The Rouge-Du�ns Wildlife Corridor provides hebitat and migratory linkages among the valleys of the Rouge River, Petticout Creck, and West Duffins Creek, as well as with the Altona Forest and other significant natural arens (see Attachment #4). Concems have been expressed by some Pickering residenu, the Rouge River Restoraticn Committee, and others, that development within the Rouge Park Neighbourhood will lead to the destruction of the Rouge-DuRins Wildlife Corridor. The following discussion explains steps taken to cnsure this does not occur. (a) O�cla! Plan Background The Corridor is one component of the Rouge Park Neighbourhood. With respect to the approved Pickering Official Pinn, the Corridor exisu specifically on lands designatcd "Open Space System - Natuml Area" as well ns "Frceways and Major Utilities - Potential Multi-Use Arca", which is the Ontario Hydro comdor. Other lends within the neighbourhood nre dcsignatcd "Urban Rcsidentinl Amu - Low Density" und "Mixed Use Arca - Locnl Node". These areas ure not part of thc designated Wildlife Comdor. As explained in section 1.2 of this Report, the Officini Pinn policics nnd designntions dealing with the Rouge-Duffins Wildlife Corridor wcre npproved by the Ontnrio Municipnl Board. All partics ngrced to u settlemcnt, with the central principal bcing that the Rouge-Duffins Wildlifc Corridor would coincide with lands designated "Open Space System - Natural Arca', ns well as "Freeways and Major Utilities - Potentinl Multi-Use Area'. The sctUement rccoRniud thnt new develapment within the neiahbourhood could co-cxist with e well-functionin¢ RouQe-Duffins Wildlife Comdor. The sctticment included thc Ministry of Municipul Atfairs nnd Housing (MMAH), which had pursucd U�e appcal on bchalf of the Ministry of Nutural Resources (MNR). The concept of a"wildlife cortidor' in this arca of the City originntcd with MNR in 1991, during discussions pertnining to the Altona Farest. By agreeing to the above settlement, MNR (through MMAH), agreed that the Pickering Official Plsn, as approved, provides an nppropriate policy and land use framework for the long-term functionaliry of the Rouge•Dutlins Wildlife Corridor. Another party to thc OMB hearing, the Toronto and Region Conscrvution Authoriry, concurs with this position. (b) Rouge Park Nelghbourhood Srudy The role of the Rouge Park Neighbourhood Study on this issue is not to substentiate future development within the neighbowhood. Rather, its role is to better define where, what, and how development occurs. The study, through the EMSP, hns refined ihe boundaries between future development and the Wildlife Cortidor, and it identifies edge management strategies that, once implemented, will ensure thut new development does not significantly impact upon the featums and functions of ndjacent natural areas that constitute the Wildlife Cortidor (see scction 2.1 of this Report). In addition, thc EMSP contains a discussion on wildlifc corridors (scc scction 3.3 of Appendix I to RepoA No. PD 07-00), It explains whnt wildlife corridors arc, and how they work. The discussion continucs by identiFying the types of spccics that arc present in this area of the City Ihat use cortidors, and lists thc rypicul corridor widths requircd by these species. The EMSP concludes by stating thut cortidor widths �, � REPORT 1Vl1MBER 07-00 Datc: February l8, 2000 Subject: Rouge Park Neighbourhood Study Page 13 within the neighbourhood are of nn appropriate breadth to accommodate thc needs of corridor-using species present in the Rouge Park Neighbourhood area. (c) Addlltonal S�eps �o Assfs� in !be Protectlon ojlhe Rouge-DqQlns {Vfldlrfe Cor�idor Establishing an Officiel Plan land use and policy framewark for the Wildlife Corridor was the first step in ensuring iu future. UndeMking the EMSP was the second, end prepazation of site-specific Environmentel Reports in order to provide detailed edge management strategies will be the third. There nre howevcr, other steps thnt cnn be tnken to assist in ensuring a henithy futurc for the Wildlife Corridor. Section 2.4 of this Report identi6es a number of Potential amendments lo the O�ciul Plan. One change involves amending the Land Usc Schedule such that boundaries between open spnce and residential areas better reflect the findings of thc EMSP. The net effect of this is tin increase of open space lands, which direcdy increases the umount of land designated Rouge-Duffins Wildlife Cortidor (nn increase of 3.8 hectazes). Once amended, the OtTicial Plan will designute 75% of the ncighbourhood as Rouge-DufTins Wildlife Cortidor. Another step that cnn be taken is the preparution of a Rouge-Duffins Wildlife Carridor Managcment Plnn. The cdge managemcnt strategies recommended by the EMSP nre dirccted nt developable Innds, but mnnagement strategics are also needed to ensure thc on-going hcnith of the Rougc-DufTins Wildlifc Comdor. The Rougc Park is currently supportcd by govemmcnt funding and the Rouge Pnrk Manngement Plan. Thc samc should be true of the Rougc-Duffins Wildlife Corridor. It is importnnt that thc Ministry of Nntural Resources, Toronto and Region Conservution Authority, Region of Durhnm, City of Pickering, Ontnrio Hydro, C.P. Rail, Intcrprovincial Pipeline, and interestcd othcrs come together to forge n partncrship to suppon the futurc of thc Comdor. This supporl �vould include the preparation of a Rouge-Duffins Wildlife Cortidor Mnnag�ment Plan, and the establishmcnt of funding for on-going maintcnance nnd restoration of lhe Cortidor. It should nlso be supportcd by un initintive of the Ontnrio Renity Corporntion to trensfer all non-developablc properties within the Rouge Park Neighbourhood to an npproprinte public authority with n conservntion mandate. An additional important step is to nFUrow the range of uses permitled within the "Freewnys and Major Utilities - Potentinl Multi-Use Aren" designntion (the Hydro comdor lunds). Currently, the Official Plan pertnits uscs that urc compatible with adjacent land uses. This mny permit uses that are compatible with residential development, but potentinlly incompatible with the function of the Rouge-Duflins Wildlife Corridor. One of the recommended nmendments to thc Official Plan (sce Appendix [V to Report No. PD 07-00), would remove this type of permission. (d) Proposed Refenflon ojA// ProvincFal Lands The Rouge River Restoration Committee (RRRC) has recommended that all provincial lands within the neighbourhood be retained in public ownership, in order to nugment the Rouge-Duffins Wildlife Corridor (see Attnchment �5). The Committcc also suggcsts that n portion of the provincinl lends could be tmnsferred to private ownership in cxchnngc for privutelyheld Innds which, in RRRC's opinion, have been inapproprintcly identificd by the EMSP as devclopnblc. Thc Rougc Purk Alliance has endorsed these rccommendalions (see Attnchment #6), nnd 1'orwunicd their resolution to the Onterio Realty Corpomtion (ORC). Through discussions with ORC represenwtives, City statf nre of thc understanding that surplus provincial lands within the Rouge Park Neighbourhood will be sold. Thc totel provincial Innd holdings constitutc neorly holf of the ncighbourhood's totnl area. However, the EMSP hav detecmined thut just 16% of those Innds ure REPORT NiJMBER 07-00 Date: Febnu�ry I S, 2000 �� J Subject: Rouge Pazk Neighbourhood Study page 14 "developable". As discussed enrlier, staff ere recommending the remaining 84% "non-developable" lands be conveyed to a public body with a conservation mandatc. Representatives of ORC have met with TRCA, MMAH and Ciry statT to discuss the prospective sale of their surpius lands. Each agency hes advocated the importance of environmentally sensitive lunds remaining in public ownership. Although ORC has yet to formally ngree to this request, there does appear to be general concurrence that public ownership of sensitive lands will be maintained. During the settlement of Appeals 1 und 2 to the Pickering Official Plnn, staff considered the merits of designating Iands us "Open Space System — Natural Area" and "Rouge-Duffins Wildlife Corridor" based on Innd ownership. We conciuded however, thnt designoting Innds in such an arbitrnry menner wns not defensible. This conclusion was shared by MMAH, MNR and TRCA. Tluough this Neighbuurhood Study, we have refined the designation of Open Space and WildliCe Corridor lands in the neighbourhood, on the basis of nntural features and functions identified on site, regardless of owncrship. Ncvertheless, it is important to realiu that upprovnl of Innd use pluns and development guidelines does not compel � landowner, privntc or public, to devclop their Innds. This principal applies to nll of Pickering. Within any given nrea of the City, if lands sue not developed as anticipated, it muy be necessary to mview nnd rcvisc any relevunt O1Ticinl Plun policics, designations and Dcvelopment Guidclines at an uppropriatc timc in the future. If this siluation werc to arise, swfiwould bring it to Council's uttention nnd seck dircction on addressing the issuc. (e) Praposed AcquJsilfan ojlhe Beare Estale/Map Realty Properly The Rouge River Rcstoration Committee hns also recommcnded that the Beure Eswte/Map Rculty property be publicly ucquired. A portion of the site is designnted "Urbnn Residential Areu — Low Dcnsity". As stnff continucs its revicw of devclopmcnt upplicntions submitted for the property (sce section 3.3 of this Repon), rccommendntions will be mnde to Council rcgarding the ownership/stewnrdship of that portion of thc sitc dctermincd by staff to bc non-dcvclopablc. 3.3 Development Applications As expinined in section 1.3 of this Report, a Detailed Review of the neighbourhood is required prior to Council considering major dcvelopment applicatiuns. Once Council adopts the Rougc Park Neighbourhood Development Guidelines and Environmental Master Servicing Plnn, this O�cial Plan requirement will be satisfied. Two mnjor development applications ere curren►ly being processed by the Planning and Development Depariment. The first proposes an "adult oriented lifestyle community" proposing a totnl of 230 residential units and I88 "retirement beds" on the Bcurc Estate/Map Realty property (norih side of Finch Avenuc, opposite Woodview Avenue). The second application proposes 56 semi-dewched units at the south-west comcr of Finch Avenue nnd Altana Road. Subject to Council's adaption of the EMSP and Development Guidelincs, swff intend to present Council with mporis on these npplications later this Spring. CONCLUSION: With Council's ndoption of the Rouge Park Neighbourhood Environmcntnl Master Servicing Plan and Dcvelopment Ciuidelines, n comprchensivc framcwork will bc cstablishcd for futurc development within ihe neighbourhood. The framework includes direction on resource conservntion, stormwater managcment, urban design, transpodation, and siting of public fucilities. p � 6REPORT NUMBER 07-00 Date: February 18, 2000 Subject: RougePazkNeighbourhoodStudy PagelS Implementation of those two documcnts along with other recommcndetions discussed within the body of this Report, will ussist in ensuring thc futurc health of the Rouge-Du�ns Wildlife Corridor. The recommendations include increasing the amount of lend designatcd as "Open Space System - Natural Area", requesting that all non-developable provincial lands be conveyed to a public agency with a conservation mandatc, and requesting that a Rouge-Duffins Wildlife Corridor Menugement Plan be prepared and funding established for its long-term restoration.

INTRODUCT/ON The City of Pickering initiated a"Detailecl Revicw" of tha Rouge Park Neighbourhood as required by the Official Pian prior to permitting major development in the Rouge Park Neighbourhood. The "Dctailed Review" constitutes a detaileJ evaluation of environmental considerations, land usc and mix, transportation network, community design, and scrvicing requircmcnts, as well as a public consultation process. The outcome of the "Detailed Review" includes: . Environmental Master Servicing Plan — An asscssment of environmental features and functions, and stormwatcr management slrategies., . Rougc Park Ncighbourhoad Development Gufdelines — General guidelines on urban developmcnt conccpls fot the Rouge Park Ncighbourhood integrating cnviromnental factors, community design, land use and transportation elements. The purposc of this report is to prescnt thc E�ivironnrenfal Master Servicing Plan for the Rouge Park Neighbourl�oal, Ti�e othcr componcnt of the "Detailed Review" has been prcpareJ by the City of 1'ickecing and is a companion report. 1.1 Overview of an Envli onmental Master Servlcing Plan Thc Environmcntal �'las�cr Scrvicing f'lan (GMSP) for thc Raugc Park Ncighbourhood addres�cs two important clements of dcvclopmcnt in the Neighbour:�ood - cnvironmental considcrations anJ stormwatcr management. Thc purpose oC thc EMSP is to mcct thc following objcctivcs: . Refine devclopablc limits of resiJcntiaily JcsignatcJ IanJs currcntly defincd in thc City's Official Plan by confirming or establishing thc natural fcatures and fun,.liuns, anJ iJcntifying approprialc protcction and cdgc managemcnt mcasures; and, . Develop a stormwater management stralcgy for the area, An undcrlying objcctivc of thc GMSP is to csmblish cnvironmcntal dcsign guidelines and management stralegics to assist in thc review anJ approval of development applications. 'fhe guidelines will bc useful to thc City, dcvelopers, local landowners, and othcr interested stakcholders, cnsuring all arc involved in thc successful planning and growth of the Rouge Park Ncighbourhoal.

The expansion nonh of thc Ontario Hydro Gatineau CoaiJor crcateJ a new Neighbourhood calied the Rouge Park Neighbourhood. The new Rouge Pazk Neighbourhood is approximately 160 hectares in sizc and is bounded to ihe west by the Pickering-Toronto border, to the north by the Interprovinciat Pipeline/C.P. Rail linc, on the South by Ontario HyJro Services Company Inc. Gatincau Corridor and on ihe east by open space lands east of Rosebank Road. Tlie Otticial Plan established basic land uses. Further, the Of6ciai Plan required, prior to major development occuaing, that a detailed review be undertalcen addressing the specifie mix of land uscs, community design, transportation, sanitary und storm water services and environmental issues. Thc study area has been the subject of several background studies. Ponions of it are in the Rouge Park and the Rouge-Duffins Wildlife Corridor. Boundaries of lhe wilJlife corridor have bccn dctermined Cor many propertics within thc study area at a previous Ontario Municipal Board (OMB) hcaring. Thc Townline Wctiand Complex lies paniatiy in the study arca. The boundaries were rcconfirmed carly in 1999 by thc Ministry of thc Naturai Environmcnt (MNR) for this Provincially Sign3ficant WcUand (PSW). Unlikc many areas within urban or rural IanJscapcs, thc study arca is well forested and connectecl ro other natural habitats. It is Jirectly connected ro the Rouge Park anJ thc Rougc River valley to thc wcst. It is bordercJ on the south by an Ontario Hydro Services Company Inc. corridor nnd on the north by the York-Durham Sanitary Sewer coniJor and a CPR track. The Townlinc Wetland complex is located within and adjacent to the study arca, and tl�e Pctticoat Creek valley passes though iL The Altona Forest is situateJ immediately south of the Rougc Park Neighbaurhood. The cuncnt iand use is characterized by scattered residential homes such that there arc numcrous small parcels in privatc owncrship in amongst largcr blocks of land held in pubiic ownership.

NATURAL ENV/RONMENT AND DEVELOPABLE LIM/TS The primary purpose of the naWral envitonment component af thc Rouge Park Neighbourhood EMSP is to identify the naWral features and CuncUons wonhy of protecdon. The outcome af this work is a definition of which lands wilhin �t►e study area may be devcloped, and what edge managements are requ'ved. Edge managemcnts refer to the treatment of the interface betwcen developtnent and natural areas that are ro be retained to provide a buffer. Thc edge treatment is w protect the natural areas from adjacent land uses, and to protect land uscs from any ha7ards that may be posed by natural edges. Edge maaagement may consist of building setbacks, but%rs, mitigation measures or physical barriers such as fencing. Evcn if areas are identified as being suitable for development, thia dces not mean that they are unconstrained. Proponents will be required to demonstrate that proposcd development wili have no or minimal negative impacts on the fcatures and functions of adjacent nawral areas. This section of thc EMSP describes the landscapc ecology of the ama, discusses functiotu of corridors, identifies ihe kcy fcatures and funcdons of natural areas within and immediately adjacent to thc study area, and detcrmiues which areas may be dcveloped. As well, this scction provides u description of Petticoat Creek and ils features bascJ on field observations, Subsequent sections aJdress edgc managemcnt stratcgies a�xl requircmcnts of Environmcntal Reports that would be rcquired as part of any devclopmcnt application. 3.1 Netural Environment The study area has bccn the subjcct of sevcral background studies. Portions of it are in thc Rcugc Park and the Rouge-Duffins Wildlifc Corcidor. Boundaries of the wildlife corridor havc bccn dctcrmincd for many properties within thc study area at a previous Ontario Municipal Doani (OMII) hcaring. The Townline Wetland Complex Itcs partially in thc stuJy area. The boundaries were rcconfirmed carly in 1999 by the Ministry of the Natural Environment (MNR) for this ProviruiaUy Significant Wetland (PSW). Extencive fieldwork has bcen undertaken in the PSW to detertninc the significant species that it supports, as wcll as its general features and functions. Far ccrtain properties witt►in the study area, in particulaz where there are development applications under consideration, more detailed biological work has becn cornfuctal as part of an Environmenlal Report. For onc largc parccl in 1hc study area, south of Finch Avcnue anJ wut of WooJview Avenue, bra;ding bird work was completed as part of a pilot study of spccics sampling techniques for Ontario Hydro - no report was prepared for this work. The available inCorniadon has been used in the identification of study area features and funcdons. i� ioaoiamm�to n�n.a« 3-1 viemo ��-'.1 SECT/ON 3 NATURAL ENV/RONMENT AND DEVELOPABLE LIMITS In addition lo simply identiFying arcas whcrc development may occur, a broadcr picture of how the study nrea functions at thc landscape acale is required. The stuJy area is one of the more heavily-forestal areas in Pickering anc! uctions of it are part of the Rouge Park. Corcidors are an issue, as certain wildlifc sPecies move among the area's patches of natutal habitat. For this Repott, ficid invcstigations werc conducted to asscss the natural features and to define iheir function not only within the context of thc Rouge Park Neighbourhood, but as part of a continuous ecosystcm. The primary objectives of the ficld investigations included: • Idcntification of significant environmcntal features; • Defining linkages bctwcen environmcntal featurcs; and, • Identification of environmentai functions. The fie1J investigations inciuded reconnaissance Ievcl fieldwork in each natural area to detcrmine vegctation communities, gcneral quality of vcgetation, presence of arca•sensitive bird spccics, wilJlife habitat and currcnt cdgc conditions. A dctailed invcstigation was not undcrtakcn idcntifying slxwific plant or fauna spccies. In addition to thc ficldwork, cxisting sources of information were reviewed and considercd. In particular thc work previously undertaken hy thc City, work done by the Ministry of Naiurai Rcsources and studics donc in support of development applications proviJc valuable information. 3.2 Landscape Ecology Unlikc many areas within urban or rural lanclscapcs, the study area is well forested and connecteci to othcr namral habiiats. It is directly connccted to the Rouge Park and thc Rougc Rivcr valley to Uu wcst. It is borJcred on thc south by an Onlario Hydro Scrviccs Company Inc. corridor and on thc nonh by the York-Durham Sanilary Sewer corridor ancl a CPR track. The Townline WetlanJ compicx is IocateJ within and adjacent to thc stuJy arca, and ihe 1'etticoat Crcek valley passes though it. The Allona Forest is situatcd immediately south of the Rougc Park Neighbourhoal. �igurc 3.1 provides an overview of 1he Rouge Park Neighbourhoal in thc contcxt of thc surcounJing natural fcatures showing thc intcgrated nature of thc currcndy designatcJ open spaccs in thc ncighbourhood.

The approximate minimum size requirement in hectazes is indicated in brackets behind each spccics. The woaf Ftog may also be considered an area-sensitive species. It breecis in woodland pools eatly in the spring and spcnJs ihe rest of the year within forest habilat. Once forests bccome too small or fragmenteJ, local populations arc in Janger of extirpation due to drying of pools or predation. In adJition to arca-sensitive species, largc blocks of habitat, cspccially if they arc contiguous to othcr natural arcas, may provide habitat for species that have large homc rangcs. Thcsc are specics that typically use eithcr a wide variety of habitats, or that reyuire very extensive areas of similar liabitat. The white-taileJ dcer is an example oF a habitat gcn:;ralist that uses a wide variery oF open and forested habitat, as well as upland anJ wetland communities. It is also highly tolerant of human activity. The mink, which also occurs in and adjaccnt to thc study arca, is morc oC a habitat spccialist. It prefcrs marshcs and watcrcourses where it (ecds prcdominantly mi muskrats, fish, and amphibians. It requires habitat to be fairly continuous, whereas deer will cross wide areas of agricultural or open land. Iarge habitat patches support more spccics than smaller ones. The large forests within the study arca and along !hc watercourscs contain a high diversity of species. According to the various atlases, 7 species of amphibians, 5 reptile species, and 98 breeding bird species were documcnted from the atlas square (10 x 10 km) in which thc study arca is situated. This is a fairly high diversity for an urban area. Signiftcant specics reported Gom thc squarc wcre Red-shouldcred Hawk, Black Tern, ReJ-headeJ Woaipeckcr, anJ Wcstcrn Mcadowlark. When several natural patches are in close proximity to each other, these patches support a higher diversity of species than samc-siud patches that are isolaeed. In addition, thcy tcnd to support species that woulJ normally be found only in larger patches. For many species, the amount of natural habitat within (he landscape is more important than Ihe size of individual patches. Therefore, some of the woodlands within the study area and in adjacent arcas suppon species that would normally occur oNy in larger habitat patchcs. 7-I IUO-0110iarl110 Repan.doe 3.q v�uoo 031 SECTION 3 NATURAL ENViRONMENt AND DEVELOPABLE LIMITS The area and environs contain a diversity of natural habitat, plus some anthtopogenic areas lhat support some of the functions of more natural areas. There tue opcn-water marshes, meadow marshes, dcciduous awamps, wnifcrous swamps, upland deciduous forests, upland conifcrous foresis, shcubby arcu, old fields, and acpve agricultural fields. Even devcloped, landscapecf lots provide habitat for some common species oF wildlife. The high diversiry of habitats support more species than landscapes that are morc homogencous. In addition, there an: cenain species that require more than one habitat type. Examples include waterfowl that nest in meadows, but forage, raise their broods, moult, and stage in wetlands; frogs that breed in woalland poots but spend the summer in open meadows; and birds that nest in Corests but feecl in open areas. The location of the study area also wntributes to its diversiry. It is at ihe base of the Lake Iroquois shorciine. This results in thc arca being undcrlain mostly by sands or gravels, but there are areas where there is a veneer oC organic soils developed over coarser matcrial. Thcsc Jiffcrcnt soil typcs support different vegetation communities ancl wildli(c asscmblages. Thc soils resul: in microhabitats so that the stuJy area supports a fcw species that are usually found farther north or south. Examples include horse-balm which occurs mostly in the Carolinian Forest Rcgion, anJ White•toppcJ aster, which is at lhc southcrn cxtcnt of its range hcrc. Thc study arca is highly connected to other nawral or undeveloped arcas. The area to thc nonh is mostly agri�ultural land, while therc arc connections to the east along the railway linc, hydro corridor and lhrough habitat patches within thc study arca. Thcrc arc also goocl connections to thc wcst nonh of Pinch Avcnue, and along thc hydro corridor io Uie south. Immediatcly to the south-west is a large block of natural habitat in thc Rouge Park. The Altona Forest is in the south-eut, and therc are Jircct connections to it via the hydro corridor and the riparian strip along Petticoat Creek. In summary, thc stuJy arca supports a high diversity of vegctation communities and plant arxl wildlife species. This is due to a number of factors: soil types, large blocks of naturel arcas, and high connectivity to other large natural arcas. The large forested areas along the Rouge River contribute to the diversity of thc area, especially for thosc species ihat are depcndcnt on IanJscapcs with a high proportion of forest. Loss of natural areas within the study area has the potentiai to adversely atfect adjacent areas. Some forest-dependcnt species could be lost in adjacent areas if the amount of forest in thc landscape fell below that requircd for certain species, and there could be changes in downsveam water quality and quantity. Although the habitat patches within thc study area are functioning well for the most part, they are depenclent on the suaounding lanclscape. In tum, lhe study area ��taaotwwmi io nc�n.d� 3-5 v�eroo � o�� SECTION 3 NATURAL ENVlRONMENT AND DEVELOPABLE LIMITS suppods the surrounding landscape, and certain amenities and functions of adjacent areas could be lost or impaired if the entire study area were developecl. 3.3 CorrldorFuncHons The unique assembly of habitat patches and linkages discussed in Ihe previous section, combine ta provide a network of linkages between the valleys of lhe Rouge River, Petticoat Creek and the West Duffins Creek, as well as the Altona Porest. This network has been named the "Rouge-Duffins Wildlife Corridor". The Rougc-Duftins Wildlife Conidor perfortns scvcral imporiant functions, incluJing: • providing passage for certain species as thcy travcl from one habitat patch to anolher; • providing foaJ anJ cover during movement; • facilitating genc flow; • facilitating rccolonization; � increasing habilat diversity anJ specics abunJance; anJ, • proviJing home ranges for ccrtain s�ries. To undcrstand thc corcidor on a funclional basis onc should look at which spccics actually usc conidors arxi what spccific rcquiremcnts thcy dcmand. Birds generally do not use corridors, cxccpt for a vcry (cw spccies. These tend to be thosc that havc rclativcly low �wcrs of flight, such as Northern Bobwhitc and Wild Turkcy (which do not occur in thc stuJy arca). Most birds simply fly from one area to the next regarJless of what habilat is bcncaUi them. Although there are a few stuJies that inJicate Ihat spccics (such as Bluc Jays) follow fence lines when they are flying, this appears to be cxceptional. Most birds use a viewscape approach, arul fly directly between habitat patches. Even dispersing young do not follow corcidors when thcy are Ieaving thcir parcnls' territory. Ccnain amphibians, reptiles, and mammals Jo use cotridors. Some amphibians anJ reptiles use different habitat typcs during diffcrent scasons. Of the seven amphibians that inhabit the study area, the IeoparJ frog is the one that is most likcly to use a coaidor. It brceds in woalland pools in springtime, but spends the summer in damp meadows, ideal conditions are when these two habitats arc contiguous, but it will movc along corridors to reach essential habitat. The best corridors are grassy mcadows, but it may also cross lawns. In urban areas, it may be susceptible to road kill, prcdation, and chemicals when it moves between spring and summer habitat. s•� �oaonomoii w tu�on.a� 3-6 v�uw 033 SECT/ON 3 NATURAL ENV/RONMENT AND DEVELOPABLE UMITS The five reptiles ihat may occur in thc nrea include the painted turtle aixi four snake species. Therc arc instances when turtles necd corcidors to uavel to gravely or sandy areas to i�est. This dces not appcaz to be the casc in the study azea, with atnple gravely arcas near the Amos Poncls. Snakes also nced to move between summer habitat and winter hibernacula. However, the four species that may be present (eastem garter snake, northem ribbon snake, northern redbelly snake, and brawn snake) all have small home ranges and have limited to no necd for corridors. Therefore, it is uNikely ihat any of the reptiles that may occur in the study azea need corridors. Mamn�al usage of corridors is variable among spccies. Some almost never use corridors; some arc indi(ferent to corridors, using them casualiy if they happen to lead to whcre the animal wants to go; while some specics preCer to use corcidors if they are moving among core areas. The following is a discussion of the corridor usage of mammal species that may occur in the vicinity of the study area. 7'�ose that never use corridors arc littic brown bat and big brown bat. Other bat spccies may occur occasionally in Pickering, particularly when migrating, such as the reci bat and hoary bat. None of the bat specics use corridors. Spccics that frcquently movc through urban areas include grey squirrel, red squirrcl, Nonvay rat, house mouu, racoon, and striped skunk. These spccies do not nccd corcidors, but may use thcm if A�cy arc availabte. In agricultural landscapcs whcrc natural habitats arc distantly spaccJ, thc skunk does rely on cocridors to get from one arca to another. Conidors do not 8ave to bc widc to facilitate skunk movcment in thcse cases, anJ fcncc lines arc usually adequate. Othcr spccics thal may cecasionally movc through urban habitat include short-tailed shrew, star-noseJ molc, castem coltontail, eastcrn chipmunk, woodchuck, dcer mouse, white-footed mouse, meadow vole, mcaJow jutnping mouse, coyote, red fox, anJ white-tailcd dccr. Spccies that am rather indif(ercnt to corridors include coyote, red Cox, and white- tailcd deer. The coyotc and (oz tend to avoiJ corridors whcn travclling across the latxlscape, preferring to stay out in the opcn. They may, however, occasionally hunt in corridors. Dcer tcnd to lravel Jirectly to wherc they want to go, and are more likely to movc in the opcn than along a corcidor. One cxception is deer migradon corridors. These are traditional routes lhat are used by dccr to rcach wintering areas from thc summer habitat, and thcy tend to be in heavily-forested amas. This is a concern only where decr yard up for the winter in large concentrations. �i too-oiw�i�o tcrooa.aa 3_7 vterou 034 SE�T/ON 3 IVATURAL ENVIRONMENT AND DEVELOPABLE LIMITS 5pecies that prefer to use coaidors may bc subdividal into those that pcefer riparian conidors to those lhat usc upland corridors. Ripazian corridor species include muskrat and minlc. Ttiese species uavel either in watereourses or along streambanks. Buffers that are normally left along stream are usually adcquate to allow these species to condnuc to movc through the landscape provided this leaves adequate habitat for t6eir prey. Species that prefer to use upland coaidors are masked shrcw, smoky shrew, short- tailed shrew, eastem cottonlail, eastem chipmunk, woocichuck, decr mouse, whitc- footed mouse, mcadow vole, meadow jumping mousc, and ermine. Olher species that will commonly use these upland corcidors arc grcy squirrel, red squirrel, racoon, and striped skunk. None of thcse species requires very wide corridors, and 10 to IS m is usually wide enough. Corridors should have adcquate ground cover in the form of tall grasses and forbs to providc protection from predators while mammals are moving through the corridor. Somc species also prefer shrub and tree cover including eastern chipmunk, castern cottontail, ermine, squircels, and racoon. Limbs, logs, ancl othcr downed debris enhance hab+tat for eastern chipmunk, caslcrn cottontail, anci erminc. Most urban wildlife is accustomeJ to using narrow corridors. Thc species that require more habitat than a narrow strip of naturai area tcnd to be thosc that do not use corridors per se, such as rcd fox and coyote. Thcse specics need a network of natural patchcs of difCercnt habitat rypes so that thcy can fulfil all of their life history functions ancl not dcpcnci on small arc�s for prey. Generaliy the wider a corridor, the more spccies that may use it. This, however, must take into account thc species that inhabit die general arca and their requirements for corridors. The wildlifc spccics diat occur in and adjacent to thc study arca are mosdy adaptal to urban lifc anJ nanow corridors will sufficc for them. CorriJors 100 m in widtli should accommalatc thc movement pattcrns of all species in the stuJy area. Even wiJcr corridors in somc arcas may be bene6cial, not necessarily as a corriJor, but as a habitat patch for spccies with small home rangcs. It must bc rccogniud that wilh urbanization movcmcnt by some specics wili be curtained. Providing for a series of core and other habitats that are connected by corridor lands is an attempt to continue to provide for species that curcently exist in this part of thc Region as thc landscape mavix changes from rural to urban. Corcidor functions are well maintained in the study area and adjacent areas as shown on Figure 3.1. East-west corridors occur along the railway line and York- Durham Sanitary Sewer in the nonh and the Ontario Hydro Services Company Inc. right-of-way in the south. Wildlife may also move east-west in the agricultural lands to the north ofthe Rouge Park Neighbourhoocl and along the hydro corridar a•��ao-o�wzoo:i�o rtepondoe 3-8 v�eroo 3.4 O3J SECT/ON 3 NATURAL ENVIRONMENT AND DEVELOPABLE UM/TS to the Rouge River valicy. There is also wildtife movemcnt between the Amos Ponds arca and We wildiife sanctuary west of the Townline. Therc is a atrong north-south connection between the Amos Poncis area north of Finch Avenue and thc wedand south of Finc6. Natural habitat occurs to the eJge of the road on both sides. Wildiife moving in this direcdon can travel north tluough the agricultural land norih of thc railway tracks, or south to the hydro corridor. Another major north-south corcidor occurs along Petticoat Creck, from the agricultural lancls to the north to Altona Forest in the south. A third nonh-south corriJor occurs eazt of Altona Road, through old-field habitat nonh of the study area, the woaled azca near the water lower, ORC lands south of Finch Avenue, to the hydro corcidor and Altona Forest. The fourth north-south corridor is east of Rosebank Road, through the foresteJ area south of the railway to the hydro conidor and to Altona Porest.

Habitat Area 1 abuts thc northwest patt of the Rouge Park Neighbourhocd. Arca 1 comprises one part of the Townline Provincially Signifcant WeUand Complex and is designated "core area" in the Rouge-Duffins Dnft Natural Hcritage Strategy (Geotnatics, 1997). This area consists of an open emergent marsh with some deciduous swamp around thc perimetcr. This feature providcs imporlant tiabitat for birds, hetpctofauna, and mammals. It is a breeding, fccding and slaging area for waterfowl, fceding habitat for several spccics of herons (Grcat Bluc Heron, Green Heron, Black-crowned Night-Heron), and fceding and nesting habitat for provincialiy and locally significant birds including Trumpeter Swan. li provides dabitat for turUes, furbearcrs, and amphibians. The MNR's wetlanJ evaluation indicates that thcrc arc locally significant plant species present. The woodcd portion is habitat for common woociland species. This portion oF thc wetland contains most of thc significant species that resulted in the welland being designated provincially significant. Because of the large siu of the open marsh, it attracts several species of herons anJ watcrfowL It is a source area, with wildlife in this area spilling over into adjacenl areas. ['or instance, it is unlikely that many herans ancf king6shers would be attracteci to the Amos Ponds if this portion of thc wctlanJ did not cxist. 3.4.2 HabltatArea 2 Habitat Area 2 includes portions of the Townline Provincially Significant Wetland Complex nnd is designateJ "core arca" in ►he Rouge-Duftins Draft Natural Heritage Sirategy. This pan of the wmplex contains deciduous swamp, butronbush thickct swamp, an cmcrgent marsh and thc Amos poixls. Thc fcaturc also includcs thc surrowxling upiancl dcciduous forest. Thc ponds providc habitat for turtics, brecding habitat for amphibians (including grccn frog, woocl frog, leopard frog and fanerican toad) and a feeding arca for herons anJ kingfishers. The buttonbush thicket swamp is a locally rare plant community. The swamp and forest contain locally significant plant species and provide habitat Cor common woodland wildlife. There is potcntial for arca•scnsitive bird spccics, and thc brccding bird survcy conclucted by Gartrnr Lee Limitect (1999) detcrmincd that Hairy Woocipecker and Pileated Woodpecker were prcunt. The forest and swamp were designated together, along with the woods in Area 3, as a significant woodlanci in Pickering due to thcir combined size, natural heritage features and ecological functions (MNR 1996). 3.4.3 Ha6ltatArea3 This feature contains the wooded Petticoat Creek conidor, some carly successional vegctation and open field. The feawre provides habitat for common upland species. The early successional vegetadon unit contributes to the size of thc forest patch in a•i toaonomm�io n��on.ao� 3-11 vieroo 1 : SECTION 3 NATURAL ENVIRONMENT AND DEVELOPABLE UMITS Area 2, acts us a link to tho riparian Petticoat Creek corriJor, and is desiguated "corc arca" in the Rouge-Duffins DraR Natural Heritage Strategy. Combined, these forest units were designateJ as a significant wooJlancl in Pickering (MNR 1996). Petticoat Crcek proviJes intermittent fish habitat and may provide breecling habitat for amphibians. There are some impaicments to habitat quality in this arca. There are two types of early successional habitat. One is an old gravcl pit that has regenerated with young trees. The ground flora in this area is almost entircly dog-strangling vine, an invasive species that chokes out native vegetation. In addition, the lack of topsail in thls area creates harsh conclitions for trce growth, and thcre is evidence of stress in some of the young vees. North of the old gravel pit, there is another young forest dominated by poplars. Although thcre is some ash regcnerating, U�e lowcr canopy is dominated by common buckthorn, an invasive shrub.

These patches and the arca bctwecn providc habimt for common upland ficlJ and woalland species. The Wnter Tower woallot was designated as a signifcant woodland in the City of Pickering (MNR 1996) bccausc of uncommon features (in this case, likely because of its trcc spccics divcrsity). In aJdition, this rclativcly mawrc woodlot may provide habitat for cavity-Jependcnt specics. 3.4.5 Habltat A►ea 5 This fcaturc consists of part of largcr mixcd and conifcrous woals.

'fhis woodland was designated as signifcant in Pickering because of its siu, natural heritage features and ccological function, and is designated "cote area" in the Rouge-Du(fins Draft Natural Heritage Strategy. Petticoat Creek provides fish habitat. The riparian corridor acts as a link from Finch Avcnue to the south side of thc stuJy arca. There aze some minor limitations to the functioning of this habitat patch. The water lablc is not as ciose to thc surfacc as the patch to Uie west. In Jrier years, it is likcly that woalland pools dry up before amphibian larvae can transform into adults. At this point, Petticoat Creek is intermittent, and is reduced to pools of water with no flow bctwcen them. 7'hcrc will bc ycars whcn thc strcam dries up before amphibians can transform, and there may be complete losses of fish some years when thc strcam Jrics up completely.

A small portion of the ncighbourhoal on 'he eastem boundary is a tributary to the Amber:ea sewershecl. Field reconnaissance was conducted to document Petticoat Creek Ceatures. The reconnaissancc included a reach of Pctticoat Creck extcnding from the northern boundary of the Rouge Park Neighbourhood at ihe railway tracks down to Sheppard Avenue. The reconnaissance incluJed walking this reach of Pelticoat Creek, Jocumcnting fcatures (outfalls, crosion zoncs, ctc.), and taking fieid measurc�nents of tcmperature and ilow. Thc field work did not include any fishery assessmcnt. To supplement the fieid work a delailcd review of thc Stage 1 Study of Comprchensive Stormwater Management Stralcgy for Altona Forest Area, Cosburn Patterson WarJman LimitcJ, Fcbruary 1994 was rcviewcd and incorporated in the assessment along witli revised flualiine mapping work approved by Toronto Region Cona•:n�ation Authoriry (TRCA) anJ thc ": ownlinc Swamp Compicx" preparcJ in April 1999 by Ontario Ministry oY Natural Resourccs, Aurora District.

It should be required as patt of an Envir:uwental Report to furiher Jocument conditions in the watershed under more typical spring and summcr conditions. As part of the walking survey of Petticoat Crcek estimates of creek flows and any L*ibutary flows (e.g. storm outfall flows) were made, spot water temperamre readings taken, photographs and documcntation of crcek features. 3.5.1 Genera/0escdpUon The Petticoat Creek watcrshed drains approximately 26 km2 of land in the City of Pickering. The watercourse is approximately 14 km in length and drains directly into Lakc Onlario. The portion of Pctticoat Creck in the Rouge Pazk Neighbourhood is approzimately 0.5 km long. From the hydro corriJor to Lake Onlario, Pctticoat Creek flows within a stcep wcll dcfineJ river vaUey. The creek has a well-cle6ned low tlow channel Ihat meanders within a wide floodplain. 3.5.2 Field Survey ObservaUons and Findings The following observations were maJe Juring field surveys: . 7'he length of Petticoat Crcek in lhe Rouge I'ark Neighbourhood is approximatcly 0.5 km; . The surfacc drainage routes shown on thc MNR Townlinc Swamp Complex mapping wcrc Jry during August 1999; . The drainage paUu in the Rougc Park Ncighbourhoal are shallow, heavily vegelated anJ not well Jefinal, other than the main channel of Petticoat Crcek itscif. Just south of tlie Finch Avenuc culvert a small pool was present on both occasions; . Spot observations of drainagc conditions in lhe Rougc Park Ncighbourhood were made in Scptcmbcr, and again no surface flow was obscrved in spitc of rain that occurced during thc previous few �days and on the morning of thc field survey. However, somc localizcd ponding in low spots wcrc observed � on Ihat had not been present in August. Also, �he level of the pool that fotms in the Petticoat Creek channel just south of the Finch Avenue culvert was higher than observed in August, alihough there was no observable flow into or out of this pool on either occasion; . T'he presence of the surraunding wetland areas in thc Rouge Park Neighbourhood indicate high local water table conditions.

The presence of more localized surface ponding and higher pooling level in the main crcek in September shows lhet the water table responded to the recent rain. The Ievcl did not rise enough to generate any significant surface outflow; there was no surface flow observed in the main creek culverts under Altona Rd at Pine Grove Avenue in August or September; and, • From Pine Crove Avenue to Sheppard Avenuc ihe crcek ravinc/valley lands are characterized by densc vegetative growth, with some stands of mature trees. This condition prevails through the bottom land to lhe very edge of the creek channel. 3.5.3 F/ow CondlUons As noted above, thcre was no significant flow observed on uny occasion in the Rouge Park Neighbourhood reach of Petticoat Crcck or at the downstream Pine Grove/Altona RoaJ culverts (triple 3m by 3m concretc box culverts). rlow observations on Scptembcr 9'", 1999 (between 10:30 am and 3:30 PM), pro�ressing downstrcam are summarized in Tablc 3,1, Tab/e 3.1 Petticoat Creek Flow ObservaUons I.ocatlon D�vcriptfon ���malcd Observed hteasurcd Flow Tcmperulure Entrance of CSP culvtrt wxtcr Al�ona R�ad neu Tranquil Ct.

The creek itseif is characterized by a cobble/stone/boulder Ilow channet that is shallow (not deeply envenched) and which varies in width from roughly 2 to 5 metres. The "bankfull" flow depth is typically less than 0.5 m; Y��oaonmoml �o nePOn.d« 3-16 viuw 043 Secnoru 3 NATURAL ENVIRONMENT AND DEVELOPAQLE LMITS • The cobblc channel appears to rc[lect Ihe surrounding glacial UII soils and overburden. Thc Soil Survey report for the former Ontario Counry notes the presence of soil profiles developecf from glacial outwash sands and gravels; for example, the Brightan scries sandy loam (with gravel and stony phases) that is mappecl in the area; • The cobble channcl appears to provide good dissipation of hydraulic encrgy under low to moderate tlow conditions; • Generally, the main creek channel and storm outfatl channels (e.g. short drop chantiel from PT18 to the creek) appearcd stabic with no sigcu of significant erosion of sedimcnt deposition; • Erosion protection (rip•rap stone over gcotcxtile) has bcen itulalled along sections of the creek between Pine Grove/Altona box culvert and the SPCSP cuivert unJer Altona just south of proposcd 5troud's Lane extension. The rip-rap is now generally overgrown by grasses, goldenrod and other plants, and appears to be in giwd condition and not displaced by high flow events; . The shallow crcek channel is gcnerally flanked by broad, level bottom land that will act as floociplain during high-tlow cvents. This provides the bcnefit oi reduced flow velociry anci (lowrate atlenuation during IIoods, which helps control crosivc potential; . There are locations where an craling bank is present. Figure 3.3 shows the crosion zones identified; . While the rate of erosion dces not appear to bc high at these sites (as indicateJ by lack of cvidencc of recent mass movcment or downstream deposition), therc is obvious polcntial for signitcant erosion and removal uf exposed bank matcrials from lhese locations during high Ilow episodes: The bank materials are erodible, consisting oC loam, sandy loam and coarser material; . Of particular concern may be the sile immeJiately east of Granby Court wherc the crcek channel (lows close to the tce of the stcep ravine slope (slope hcight esdmatcd at 8,0 m) ihat is prescnt at the rear lot line of residentiai propertics on the east side of Granby Court. Thcre is erosion occurring at the bottom of this steep, treed slope; and, .

The wetland complex, drainage routes and crcek in the Rouge Park Neighbourhood area are hydraulically linked with groundwater systems; • The character of the local vegetative communides and ecosystem linkages in tlze Altona/Finch/Sheppard portion of Petticoat Cmek watershed is summarized in the Altona Forest Gnvironmental Management Plan (MTRCA, 1996), which notcs the significant role of this area as pan of the Rouge-Duffins Wildlife Corridor; . In general, ihe creek is gcncrally frce of widespread or severe erosion problems, cxcepting thc erosion silcs noteJ above. At low to malerate tlows, crosion susceptibility may be low, by virtue of the encrgy dissipation anci physical protection providcd by thc cobblc channel and the erosion works now in placc; . At the erosion sitcs notcd abovc, higher tlows and tlow vclocities will cause removal of material Gom craling banks and slopcs, and this may bc a concem from the point of vicw of downstream habitat and ecosystem protection, as wcll as adjacent property proteclion. Any significant changes in ilow regime (espccially incrcascd Gcquency and duration of tlow bcyond the capacity of thc main cobblc channcl) will bc a conccrn; and, . The creek tu�s becn categorized as warmwater aquatic habitat (Altona Forest Envumunental Managcmcnt Plan, MTRCA, 1996). 3.5.6 Flood Suscep06le Areas Petticoat Crcek floalplain has bccn mappcd by TRCA from Lakc Ontario to Taunton Road. In the Rouge Park Neighbourhoal there are no flood susceptible areas where public or private property is at risk. The floal wlnerable areas are locateci in the arca of Pine Grove Avcnue and Altona Road, and bctween Highway 401 and Kingston Road. 3.5.7 PetUcoat Creek Summary T6e following is concluded from the field reconnaissance and mview of available historical infortnation: . Petticoat Creek can be ciassificd as a warmwater aquatic habitat; 7•t ioo-o�m�ooii io �on.doc 3-19 v�emo 045 • SECTION 3 NATURAL ENV/RONMENT AND DEVELOPABLE LIM/TS • Level 1 protecdon should be applied when considering stormwater mamgement feawres. Level 1 protecdon hes been setceted becauae of the ialeracdon between the crcek and the weqands as well as the dowastream features and Po�tions of Petdcoat Creek; • Erosion is evident at selected locadons requiring erosion controls W mitigate further erosion with upstream development; . Groundwater levels affect creek tlows in the Rouge Pazk Neighbourhoal; and, • The wetland complex, drainage roufcs and creek in the Rouge Park Neighbourhood area ere hydraulically linked through groundwater systems. 3.6 Deve/opa6le Envelopes Figure 3.4 shows areas of land witlw► the Rouge Pazk Neighbourhood that aze considered developable. Dcvclopment areas have been idcntifed by numbers for ceference purposes only. Thc rationale for defining the developable envelope is based on the following principles: . Reference to the OMB-approved tesolution to Appeals A1 and A2; thc Boazd's decision includes Minutes of Settlement, which idendfies certain lands as being devclopable (the discussion focuses on lands on the north side of Fi�xh Avenue, east of Altona Road, and a pocket of land on the west side of Woalview Avenue, south of Finch Avenue); . Gxclusion of lands tdentifiai within the revised weUand boundary for the Townline Provincially Significant Wetlnnd Complex, plus appropriate buffers - which may vary depending on the edge management technIque cmployeci; . Exclusion of vallcy and stream corridors; • Exclusion of upland wooded habitat contiguous to wetlands and valleylands; . Exclusion of key lands providing/augmenting hebitat linkages (linknges shown in Figurc 3.4); and, • Exclusion of areas where development would have significant negative impacls on the features and (uncdons of the Rouge-Duffins WildliCe Corridoc • ' The deSclopable areas identified on Figure 3.4 aze approximate in their delineation. Areas not identIfied as developable will become part of the Rouge-Duffins Wildiife Corridor. As development applicadons are submitted and reviewed, detailed site investigations of ihe applicabic property will result with a more precisely definal and surveyed limit of development. Thls is currently the case for lands adjacent to Area 1 where a dcvelopment applicatian is activc.

LAND USE PLAN 043 sECnonra LAND USE PLqN As PlckerL�g continues to grow and evolve, design excellence must be promotal when basic communiry building blocks aze conswcted, including streeta, pazks, public squares, shops and residential neighbourhoods. Communiry design should focus on the reladonship betwecn, as well as the visual character and aesthedc qualides of, the City's basic community blocks. T6e Rouge Pazk Neighbour600d presents an opportuniry to e�cemi� these relationships, and establish elements of good neighbourhood design prior to the area developmendre-development. To this e�, 1he City has undertalcen an extensive planning and consultation process to establish altemative co�eptual neighbourhood designs that fit within, and complement, the developable limits previously defined in Section 3.6. Tluough the consultation pracess with Ciry and Regional staff, land developers, tandowners and other stakeholders the City tias prepared a concept for Ihe Rouge Park Neighbourhood. Found wit6in the Rouge Park Neighbourhood Study - Phase 2 Report, Neighbourhood Development Concept "E" conceptually identifes a variery of residential densities an elementary school and a neighbourhood park. The land use shown is used in dcfming stormwater managcment strategies. This plan provides a vision of the neighbourhoocl's' land uses, densities and coverage, which are importanc factors in the detertnination of appropriate stormwater management strategics. The plan is canceptual only, and does not i�lude buffars anci other necessary edge management tools. This plan is not intended to iilustrate thc actual manner in which the neighbourhood will develop. �uaaonmovtuo t�o�.da ,41 y�rroo . �. > , . ----� 050 SECTION 5 ENVIRONMENTAL REPORT 6. ENVIRONME.N7AL REPORT Although developable areas have been identificd, this does nat mean there are no constralnts to development in t6ese arcas. For most propertics in the Rouge Pazk Neighbourhood, the Pickering O�cial Plan will require that an Environmental Report be submitted with development applications (see secdons 15,8, 15.9 and 15.11 of the Official Plan). The Environmental RepoR is a detailed asscssment of the proposal and its potential ellects on surrounding natural features and functions. The Environmental Report will as�ess the posidve and negative effects of thc proposed development on the environment, and provide recommendations to prevent negative effects or enhance positive effects. Where potentiai negadve effects aro unavoidable, the report will recommend actioas to mitigate or remedy the negative effect. The Environmental Report should also idendfy any restoration opportunities to cnhance conditions over what exists today. The Environmentai Report wili be subject to review and approval by the City and othcr Regulatory Agencies. For the natural environment component of an Environmcntal Report, it may bc nccessary for proponents to undertake breeding birJ surveys and botanical studies. Inventories should bc completed during spring, summer, and autumn to determinc the full range of specics present. DcpenJing on the nature of the proposed development and the adjacent natural habitat, it may bc necessary to compietc studies that are more detailed. These may inciude, but not be limited to, amphibian and reptile surveys, description of fish habitat and fish species assemblages, and detcrmination of wildlife movcment patterns. Proponents are urged to consult 1he City prior to undertaking fieldwork to determine what studics will be requircd in support of their application. The Environmental Report will prccisely define thc developmcnt limit on-site, and identify thc appropriutc cdge managemcnt — buffers, building setbacks, mitigation, and rehnbititadon (if nccessary). See Section 6 for n discussion of edge management strategies. As part of the Environmental Report, a detailed Stormwater Management Rcport wili be required. Thc detailed Stormwater Management Report is to be baseci on the stortnwater management suategies outlined in thc EMSP report and is to address stormwater issues such as quantiry and quality cantrol, erosion controi and groundwatcr management as well as detaileJ siting and design of facilities. Section 7.0 has furthcr discussion on stortnwater and groundwater management issues and sirategies. The following describes the topics that Environmcntal Reports should addmss wherc dcvelopment is proposcd.

Edge Management Overview Whcre development may occur adjacent to natural habitats, there may bc a nced to manage the inrerface between natural and developi.�cl areas. The purpose of this is to ensure those direct and indirect effects on the feamres and functions oC namrai amas arc minimiud. Development has the potential to have cenain Jirect and inJirect effecW on adjacent natural areaz, and tliese effects may occasionally be substantive if appropriate mitigation is not undcnakcn. lmpacts may occur during construction and also from the presence of a new human population oncc the area is developed. Potential impacts during construction include noise, dust, soil compaction, erosion, scclimcntation and changcs to drainagc. Thesc typcs of cffccts can usually be minimiud or eliminated if bcst management practices are followed during construction. Even beyonJ const�uction, U�e same impacls will need to need managed atxl mitigation measures taken. A numbcr of impacts may occur if new cdgcs are established by rcmoving existing vegclatian. Thesc may include loss of interior habitat, invasion by non-nativc piant species, parasitism of bird nests by Drown-hcaded Cowbirds, penetration of wind and light drying the undcrstory, and winJttuow. Sunscald is oRen mentionecl as an impact, but this is a rare occurrence Ihat alfecls only trees wiAi very thin bark. Thc presence of humans and their pcts also may affect the quality of adjaccnt natural azeas. Human activitics that may result are cncroachment of yards into natural areas, dumping of bcush anJ lawn clippings, vandalism of vees, development of informal trail systcros, noise (lawn carc equipment), and disturbance of wilJlife. Pets may also havc deleterious effccts, primarily due to predation on wildlife species. When proponcnts aze preparing an Environmental Report, all of the potential impacts indicated above should be discussed in addition to ihe site-spcciftc topics identified in Section 5. )•I IOD-0I�U2002110 R�port.doc (_] vieroo 056 SECTION B EDQE MANAGEMENT STRATEG/ES The type of edge managcmcnt requireJ depends upon the nuturul features and functions that occur adjacent to thc property, and on thc type of development that is proposed. For example, different edge treatments may he rcquired for adjacent lands that are wetlands than for upland areas. In aJdition, setbacks for single residen�es may differ from multi-unit buildings. Figures 6.1 to 6.3 provide generic examples of types of edge treatment that might be considered. 6.2 Rouge Park Nelghbourhood Edge Management In the Rouge Park Neighbourhoal, potcntial edge tteaunents are described below. Optimal edge treaunents will be Jetermincd tivough preparation of an Environmental Report (see Section 15.11 of ihe Pickering OCficial Plan), which will have more dctailed infotmation rcgarding proposcd developmenl and thc natural resourccs of 1he site and adjacent lands, than is conGlincd within this repon. In the Rouge Park neighbourhoal, thc following cdge managemcnt conditions cxist that need to bc addresscd in an Environmental Rcport. Figure 6.4 highlights the different eJge types in thc Rougc Park Neighbourhood. 6.2.1 Areas AdJacent to Roads or Exlsting Development In some instanccs, no bu(fcr or cdge treatment will bc mquired. For cdgcs adjaccnt ro roaJs, the City's strcctscaping nolicics will have to bc considered. In keeping with thc fact that thc Ncighbourhoal is important for wildlifc movement, consideration shoulJ be givcn to thc alignment anJ dcsign of roads to allow for the avoidance of con0ict bctween wildlife and traffic promoling lhe safe movement of species between habitats. Plants used in IanJscaping should be native stock whcrcvcr pocsibic. 6.2.2 Areas Ad/acent to Dlsturbed Habltaf Thcse may incluJe carly succcssional arcas, thc hydro corridor, or tlic York- Durham Trunk Sanitary Sewcr. Thcsc types of sitcs lend themselvcs well to habitat improvement Uvough planting of nativc trces and shrubs. This witl enhance wildlife conidor functiotu anJ provide foal and shelter for wildlife. 8.2.9 Areas AdJacent to Watercourses A buffer along Petticoat Creek of at least 10 m is rcquired from eilher thc top of stnble bank, Regional floodline, or cdge of woody vegctation contiguous with the watercourse, which ever is more slringent. If lot lines end at the bu(fer, a furthcr building setback may be required, depending on the nature of the development. For inslance, it may be acceptable to have minor developments such as gardcn sheds near the edge o! the bu(Cer, but single dwellings should be at least 10 m distant from the buffer. Larger building setbacks may be required if more intensive development is requircd. 3-i ioaoiwxoolito t�pon.aoe 6_Z v�emo � ;�v ��;;�s� -�.K �..�; ;�3' � ��! <<���� ����; .�k ,�; �, �,�{.�}� k}L�+j7 � it'! 5" �,��• "��.: .�; y�' • �: fk�i;, r�.� � { �. r � �c,� « �.;�`,�� ���x, � ����: �,, a�, ��;5 .: �n �, rµer �l� F�i r: 4 ���: � �ktk� u% F»�.. �SE � ty: 4K::`r; �h� �: `�jr . �E�; t,. .. �X;€�i`� �L h ''-�. �;: 1 ,.Y "'{ `'. 4 i€t�._= til�: t � {Y � '�; .,.�yi..w • ��'zr€,°: • i £ti ' �i � • ��� "t `���:';' • ,� �'f �; �; .1� � �, �1 "'�� 4..m ,:� ,�i � s � �'�`i �� �. -^�i �70 � - ���.:�_ � a � - a � � +:� 5C z�c',', o ., �-, a 'c-,.

This may require fencing if thc numbcr of people may result in loss of shorelinc vegclation or direct erosion. If practical, living fcnces of native thorny shrubs should be considered to inhibit human movement. Thcse features do not impair wildlife movement and may provide food and cover. There are often opportunitics to cnhancc watcrcourscs. One of the most e(fective wuys is to establish riparian vcgctalion by plandng trccs or shrubs, or simply allowing natural regeneration to procced. This has many benefits such as maintaining water tcmperatures, stabilizing banks, providing esscntial nutrienls and food for aquatic invertcbrates and fish, and enhancing wilJlife habitat. Pctticoat Crcek wherc it ilows through the hydro corridor is one location that would benefit from aJditional riparian vcgelation. 8.2.4 Areas Ad/acent to Wood/ands At a minimum, the dripline and 1 mcuc must bc maintained as a butfer where no developmcnt, grading, or consttuction activity may occur. This buffer may need to be inereascd if the cdge trees have root zones scnsitive to human activiry or construcdon activity. Thc buffer may necJ to be largcr iC the woallot is associatcd with n local wetland (rcfcr to Scction G.2.5). In addition, buildings will havc lo bc set back from the buffer. The distance of setback will depend on factors such as the type of developmcnt proposeJ, nnd thc type of trees in thc adjacent woodland. Largcr setbacks may be requircd if lhc adjacent trecs are tall and could pose a hazard, if trecs have a shatlow root system that is dependent on watcr near the sutface, if tlie development coulJ shadc trces that werc previously in full sunlight, or if the woodland contains significant or sensitive spccies. If fencing is required, a living fence (hedge row or other form of barrier plandng) should be considered. It may be possible to enhance some woodlands by tree planting or promoting natural succession in bufCer arcas. This may add to thc overail size of woodlands, enhancing their capability to provide habitat to area-sensitive species. The shape of woodlands may also be improvcd by filling in irregular edges. �-itaaoiw�ooi�to tu�n.a« v�eroo 6-7 os� 6.2.5 SECT/ON 8 EDGE MANAOEMENT STRATEOlES If n new woocllund edgc is createJ, Uie EnvironmenWl Report should consider factors such as windthrow, sunccald, invasion by non•native spccies, drying, aiui loss of interior habitat. The Environmentnl Report must demonstrate that U�erc will be minimal negudve impacts, or idcntify mitigation measures that will minimize 3mpacts. Possible mitigation may inciude revising �he site plan to avoid crcating new edges, pre-stressing, planung conifers or othcr species at ihe new eclge to tnhibit wind through ihe naturai area, planting other cdges of the natural area to increase interior habitat, and cnsuring that tcsidual trees on the edge arc heallhy and sound. Proponents may identify othcr effective mitigadon measures; Areas AdJacent to WeUands In the Rouge Park Neighbourhood, thc main wetland habitat is the Townline Provincially Significant WeUand. Environmental Repons prepared Cor developmcnt ptoposcd within "dcvelopable areas" aJjacent to the wetland must proviJe cdge management strategics that will minimize impacGS on the fcatures and functions for which the azea was idcntified. • Buffer width and building setbacks from the buffer will vary dcpcnding on the type and intcnsity of proposed development. To dctermine how wide a buffer from U�e wctland should be, thc foilowing factors should bc considcrcd: • Surfacc water yuality anJ quantity dischargcs to thc wetland should be maintaincJ; . Croundwater quality anJ quantity shoulJ not bc altcred as a result of devclopmcnt; . Natural, healthy upland woalcd habitat adjacent to thc wctland should be retaincd as a buffcr, as thcse urcas may bc important to spccies that require both wctland and upland habitat during their lifc cycle.

The actua( buffer rcquired to filter out contaminants will vary dcpcnding on factors such soil typc, slopes, type of devclopment, type of contaminant, and naturc of thc wctland at this point; • Disturbance to wildlife and habitat fcatures by humans and pets as a result of development should be considcrcd. The amount of bufCer and setback required will depend on the sensitivity of the species and habitats in the wetland and the numbers of humans and domesticated animals that arc anticipatcd to visit the wctland; �•uoaaiwwmuo a�n.a« 6-8 v�uoo '_ 063 SECT/ON 6 EDQE MANAGEMENT STRATEOlES 6.3 6.4 • In some insmnccs, fcncing may bc required to limit wcUand Jiswrbancc.

In somc areas, fill has been piaced in weqand habitat, and'removal of fill wouid reslore more wetiaiul habitat and functiqns. In uddition, proponents should revicw the Temperatc Wetland Restoration Guidelines to see if there are restoration techniques that can be appiied in buffcr areas to enhance wetland functions.

STORMWATER MANAGEMENT STRATEGIES The objective of developing a comprehensive stormwater management stratcgy is to define stonnwater management features for thc Rougc Park NeighbourhooJ. The stormwater management strategy must consider the management oF stormwater and grounJwater as a resource, and the protection and maintenancc of weUands and watercourse habitats. Thc stormwater management philosophy for the Rouge Park Ncighbourhooci is founded on the concept of souree controls and communal facilities. Elements of the stotmwater management strategy arc designed to be compatible with land use planning while addressing regulatory requircments of quantity, quality, erosion and baseflow control as featured in the Ministry of thc Environment Stormwatcr Management Practices Planning and Dcsign Manuai, lune 1994. The purposc of this section is to prescnt the stormwater managemcnt strategics for the Rouge Park Ncighbourhoal bascd on a devclopmcnt schcme consistent with Neighbourhoal Devclopment Conccpt "E" of the Phase 2 Report.

Generully, the Rouge Pnrk Neighbourhoocl land falls from Ute northwest to thc southeast, except for the area adjacent to Petticoat Creek. As such, the developable urea can logically be divided into three storm drainage areas as shown in Figure 7.1, the first to ihe west surrouncling Woodview Avenue, the second centrally located around Altona RoaJ and the last area to the east adjacent to Rosebank Road.

Rosebank Road and WitJOowcr Drivc, souA� oC Pinch Avcnue. The available � capacities of the Woalvicw and Roscbank sewcrs wcre investigated. � The Woodview sewer was designed lo accept stormwater drainagc Gom the areas adjacent to Woafview Avcnue at a 0.20 runo(f coefficient (equivalent to an undevelopcd arca, or pre�dcvelopment conJitions) for a 5 year design cvent. The Rosebank scwer was not siud to accommalatc any additional flow from thc Rouge Park Neighbourhoal. The Rosebank slorm sewcr dischargcs into an existing srormwater quality poncl locatecl at 5hcpazd Avenue, west of Autumn Crescent. This facility was dcsigned as a qualiry pond to provide ueatment of a 25 mm raintall event. The Altona area has no local storm service to conncct into and will require a new outfall into Petticoat Creek. Based on the location of each of the three development azcas, it was initially conceived in Phase 1 that sturmwater generated from the Woodview and Altona areas would be ueated at ncw facilities. Stormwater from dcvelopment areas wcst of Rosebank would largely be serviced back to Aitona Road, except for a small area 3•uoo-o�w¢oo�i io temon.ua 7-2 v�eroo 0 6 G • sECnoN 7 STORMWATER MANAOEMENT STRATEOIES assac3ated with Rosebank Road, which would wntinue down Roscbank into U�e existing atorm sewer. �uoaotwmmuoncpon.ax �-3 " vierao _ oss 7.1.1 7.1.2 SECTION 7 STORMWATER MANAGEMENT STRATEGIES An analysis of the existing storm sewer on Rosebank Road and Wildflowcr Drivc was undertaken to determine the peak flow that could bc conveycJ to the cxisting pond to determine the extent of the Rosebank area that could be scrviced directly. The analysis determined that 52 Us of stormwater from the Rosebank nrea could be accepted and conveyed to the existing ponJ by the existing storm sewer. This peak flow corresponds to approximately 0.5 ha of development atea resulting from a 5 year storm event which would accommodatc Iceal road drainage from Finch Avenue and Rosebank Road. � Therefore, storage for stormwater control from the remaining 9.8 ha, west of Rosebank will need to bc provided elscwhcre. To minimize the number of facilities required for the study area, it is suggested, as in Pliase 1, that stormwater generateil in ihe Rosebank area be conveyed and treated at the proposed Altona facility which wiil be sized to provide storage for both arcas. QuanUty Requlrements Storage requirements were estimatcd to mcct stormwater quantiry guidclines. Thesc guidelincs rcquire that post dcvclopment tlows not excccd predevelopment flows.

Table 7.3 presents U�c stormwater quality storage requirements. In comparing Tablcs 7.2 and 7.3, the rcquired pond volume for Woodview is 2,850 m� permanent pool nnd 1,210 m� active pool for a total of 4,060 m�. The Altona facility will require a permanent pool of 2,740 m' and active pool of 1,100 m� Cor 3,840 m�. The Roscbank storage rcquires a 105 m� permanent pool and 20 m� active for a total of 125 m'.

Along much of the crcek, the creek has developed in soils that can bc considered as erodible (c.g. non-cohesive sandy loams). The proposed development will increase runoff volumes. Without adequate stormwatcr management, the frequency and duration of erosive Ilows will increase at downstream locations along the creek. Continuing or aggravatect crosion wili result in degraded water qualiry, Jamage of aquatic habitat and possiblc safery risks or propeny damagc. This study is intended to evaluate potential erosion impacts in an effort to providc planning-level rccommcndations on thc amount of urban stormwater Ilow control necded to address crosion concerns downstream along Pctlicoat Crcek. Appendix B presents the icchnical information and additional dctail uscd for thc crosion impact assessment. 7.2.! MethodofAnalysis The methocl of analysis can be summarizcJ as follows: I. Computcr modclling softwarc (QUALIiYMO) has bcen uscd to develop a streamilow simulation malcl for Petticoat Crcck. Thc malel considers the entire watershcd and uscs accepted hydrologic principles and tcchniqucs to computc runoff volumcs and strcam Jischarge in response to precipitation data supplied lo thc malcl. Therc are no known strcamflow data for Yetticoat Creek, so it has not becn possible to calibrate tl�e modcl or verify its accuracy. Howevcr, U�c malel dcvclopcJ for this project has•bccn partly based on a previous I�yJrologic malcl documcntcJ in the 1993 report "Hydrolo�y and Iiydraulics Upcfalc for Main Pctticoat Crcck: Stagc 1 Study oF Comprchcnsive Stormwater Managcmcnt Strategy for Allona Forest Area" (Cosburn Patterson Wardman LimiteJ, Dcc 1993).

For the existing land-use condidon and for Ncighbourhood Development Concept "E" dcvelopment, indices of the erosivc power of simulaled streamflow dave been computed for two locations along Petticoat Creek: — Along the main channel at a location alongside the northeast corner of Granby Court (approximately 300 m upstream of thc twin culverts at the CNR tracks); and, — Along the main channel at a location approximately 100 m downstream of the outlet of the Sheppard Avenue culvert. Creek cross-sections were surveycci at these locations on November 15, 1999, and samplcs of channel bed materials were taken to allow for assessment of erodibility and critical erosive velocities. Using simulated streamflows, indiccs of erosive power have been computeJ via t6e QUALHYMO mocicl using the methoclology described in the 1982 MNR report "Vulncrability of natural watercourscs to crosion due to differcnt flowrates". Analysls Resulfs The malel has bccn used to examinc thc impact of proposed land devclopment on pcak flows ancf volumes gcncratcd by the 5-year storm. Without stormwater managcmcnt, it is estimated that 5-ycar peak tlow in Pctticoat Crcek at the CNR will incrcasc by about 15%, and cvcnt runoff volumc will increasc by about 4%. Erosive impacts have bcen examined by computing the erosive impulse dclivered to the banks of Pctticoat Crcck (at thc two locations noreJ above) tor thc perioJ May 1 to Oct 31, 1981. This six-month periocl was choscn as a lest perioct sincc modclling results indicalcd tl�at it incNdes a goocl rangc of smaller, malerate and larger runoff events. Malelling tcsulls for thc perial show that at the creek location below Sheppard Avcnue, dic erosive impuisc coulJ incrcasc by 40% to over 200% at dcpths abovc channel bottom of 0.3 to 0.6 mctres if there is no stormwater tnanagemcnt for the proposed development. At this location along the creek, Uie banks are characteriuJ by active erosion of eralible sandy loam matcrial that is bare and exposed for up to 1 metre up thc bank. Control of downstream erosive impact will require detention and controlled release of stormwater from new development azeas. The model has been used to cstimate what volume of stormwater detention for each of the three development blocks will be needed to reduce thc erosive impulsc to near existing Icvcls. �i ioaoiwmmim rt�n.a« 7-8 x��eroo • 072 SECTION 7 STORMWATER MANAQEMENT STRATF.Q/ES A sequence of modol runs wns used to arrivc nt th� following conclusions on detention volume nceded for erosion control as prescnted in Table 7.4. The detention volume shown in Table 7.4 docs not include a permanent pool required for qualiry conuol. The outflow rates represeuts the erosion tlucshold. The erosion ttveshold is impormnt in the design of the facility outlet structure.

The challenge for the designer may be to achieve a rating curvc modified for erosion control that can indeed return to the rating curve for peak flow control at the 100-yr point. The shape of rating curve for peak ilow control might bc achieved by a simple broad-cresled weir.

Stormwater Facillty /mplementadon Plan Fac(Iity Sitlng The opporiunity to site stormwatcr management wet pond facilities is somewhat limited within the developable arcas. The use of lands inside the development limits will take away from the alrcady limitcd development potential in the area. Altcmative sites were invcstigated including the use of the hydro corcidor located at Ihe southern limit of thc Rough Park Neighbourhood. Preliminary discussions have been held with Ontario Ilydro Services Company Inc. in consultation with TRCA regarding use of corridor lands for stormwater managcmcnt facilities. At this time, the corridors represent a feasible altemalive for stormwatcr management facilitics bascd on thc land requircmcnts and proximity to hydro towers. Realizing the hydro corridor ns a location for stormwater managcment facilitics will rcquire developers to meet thc rcquirements of Ontario Hydro Scrviccs Company Inc, rcgarding a land lease, securing easements and satisfying siting critcria relatcd to tl�c function oF the corcidor for delivering power. My (acility in thc corridor would bc subject to approvai by Flydro, the City and TRCA anJ eventually bccome tl�e responsibility of lhc City to maintain. In siting thc Woaivicw aixl Allona stormwater managemcnt facilities, the hydro corridor has bccn identified as the preferrcd location. In the event an agreement cannot be rcacheci with Ontario Hydro Services Company Inc. altemativc sites would need to be icientified within thc devclopment envelopes. The land requircmcnts idcntified for each facility is based on minimal BMPs being employcd. Developers shoulJ imcstigatc and incorporate DMP and infiltration features with the objective of minimizing the storagc requiremcnt by maintaining storrttwater as close to source as possible. Keeping stormwater at the source has clear benefits in maintaining local groundwater conditions, maintaining base (low in Petticoat Creck, reducing the size of engineered stormwater management facilities, minimizing the potential af increases in water temperature of stored water and viewing stormwater as a community resource. 3-I I00-01102001� 10 Repon.da �_� 2 LIE/00 O 7 6 SECT/ON 7 STORMWATER MANAGEMENT STRATEQIES Woodview Fecility As previously discusscd, a storm sewer will Collow Woodvicw Avenue and connect inta the exiting storm scwer south of ►he hydro corridor. The stormwatcr management pond for this development block is best sited at the southern most boundary of the Rouge Park Neighbourhood (northern border of the hydro cortidor). It is possibie to site the facility on either the east or the west side of Woodview. The east side is less intrusive in thc hydro conidor. The storage volume identified is approximately 6,650 m�, this volume equates to a land rcquirement, inclusive of landscaping of approximately 1.0 ha (re[er to Appendix D tor pond "foot print" sizing). Tl�e facility outlet should be designed to satisfy ihe erosion thmshold of 190 Us — this may incrcaze tl�e activc storage requirement. Figure 7,3 shows the ulternative locationt in the hyJro corridor for thc Woodview Avenue facility. The ezisting outlet structure to Petticoat Creek should be invesdgated to ensurc Ihat there is sufficient cnergy dissipation and crosion protection. Thc rntionale for selecting thcse altemative locations include: • Natural drainagc routes; • Road network; • Access to facilitics from local roads; • Minimum impact on natural area features anJ functions; and, • OverOow routcs from thc facilities arc to natural arcas bcyond the dcvelopment cnvelope. Alfona Faclllry Thc Attona facility is largcr, rcquiring a volumc of 9,740 m', or a"footprint" arca of approximatcly 1.5 ha with appropriatc landscaping (rcfer to Appendix D for pond "foot print" sizing). Thc facility outlet should be dcsigned to satisfy the erosion threshold of 410 Us — this may increasc thc aclivc storage rcquirement. The facility can bc locateci on ihe east or west side of Altona road in the hyJro corridor. The west side location is aJjacent to Pctticoat Crcek and may have somc sitc constraints givcn thc proximity of thc Creck. Altematively, the facility can bc located on the cast side of Aitona Road and still discharge to Petticoat Creck. Rcducing lhc volume requiremcnt tluough source control would make the west side location more desirabie as a stormwatcr management facility and be less inwsive on thc hydro corcidor. If the hydro corridor werc not available, then the facility would be located within the developable limits of Area 7.

Thc currcnt dcsign approach is that foundation drains outlet to the stortn sewer system, whic6 ultimately drai�u to nawral watcrcourses such as Petticoat Creek. field investigations along Petticoat Creek in 1999 dcarly showed that creck base(low was being fed by dry-weadier auttlows from urban stom► ou►falls, and Uic sourcc of this dry-wcatt�cr scwcr ilow is likely partly or mostly faundation drainage. In arcas adjacenl to protected weAands, the net e(fect of founJation drains may be to divcrt groundwalcr away from thc wcdanJ. As such, foundation drains can potentially causc significant luwering of laal walcr tablc. Wliilc the divcrted groundwater may help to maintain basetlows in downstream watercourses, local lowering of walcr table cuuld resull in negative impacts on weqand hydrology. For devclopment arcas surrounding Woocivicw Avcnuc, Pinch Avcnuc anJ Altona Road adjaccnt lo thc wcUand complcx and Pctlicoat Creck, this issuc should bc addresscd property-by-properry by cxamination of proposcJ building foundation drain cicvations vcrsus wctianJ walcr clevations and estimareJ pcak watcr-table Icvcls ovcr the dcvclopmenl propertics. This will lead dirccdy to a detertnination of whethcr or not proposed foundalion Jrains will have localiud water-table impacts. Seasonal variations in the water tablc must be considcred. In gencral, it will obviously be desirable to locate builJing foundations above the seasonaily high water-table level, both from a building protcclion perspcctivc and wetland protcction perspective. If in ccrlain cascs building foundation drains are proposcd to be cituated below estimate peak water-tabic levels, then the buiiding and site design should be reviewecl in detail to see iC potential local water-tabie lowering can bc avoideJ, The result of this type of investigation may Iead to development where foundation Jrains are not desirabic that take watcr away from the area to storm scwcr pipcs. a• i i000iw2omi io rt��,r�.u�c 7-24 v�eroo 0 8 g SECTION 7 STORMWATER MANAGEMENT STRATEGIES Mitigativc mcasurc may includc no bascmcnts (no nccJ for founJation drains), or use oF sump pumps to intercept foundation (low and pump tlicm to surface locally. 7.5 Summary-StormwaterManagementStrateglos As part of thc stormwater planning proccss stotmwatcr managemcnt facilities were sized to proviJe the level of protection requircd lo achicve quantity, quality and erosion control. The sizing represents the worst-casc facility siu givcn no BMPs or souree controls arc implemenled. The use of BMPs anJ other flow rcduction or control techniques will result in smalicr stormwater management facilities.

EMSP SUMMARY The foilowing secdon provides guidance on the prcpazadon of environmcatal documents that will need to be prepared and considered with any development in the Rouge Pazk Neighbourhood. 8.1 Developmonf Umlts The developable limits as defined in tliis study are approximate and subjcct to some change with detailed fieldwork to support any change. The devclopable limils have been refined for the City's Official plan designadng a greater portion of the Rouge Pazk Neighbourhood as Open Space, Thc rationale fot defining the developable areas is based oa the following principtcs: • ReCerence to the OMB-approved resolution to Appcals A1 anJ A2; the ' Boazd's decision includes Minutes of Settlement, which identifies certain lands as being developable (Ute discussion focuses on lands on the norlh side of Finch Avenue, east of Altona Road, and u pocket of land on the west side of Woodview Avenue, south of Finch Avenue); . Exclusion of lands identified within the reviscd wetland boundary for the Townline Provincially Significant Wet1anJ Complex, plus appropriate buffcrs - which may vary depcnding on thc cdgc managcmcnl technique employecl; . Exclusiou of vallcy and stream corridors; . Exclusion of uplanef wooded habitat contiguous to wetlands and valleylands; . Pacclusion of key lands providingJaugmenting habitat linkages (linkages shown back in Figurc 3.3); and, . Ezclusion of atcas whcrc devclopmcnt wou1J have significant negative iropacts on 1he feamres and functions of thc Rouge-Duffins Wildlifc Coaidor. Areas not identified as developable will become part of the Rouge-Duffins WildliCc Corcidor. As devclopmcnt applications are submitted and reviewed, detailed site investigations of the applicable property will result with a more precisely defined and surveyed limit of dcvelopment. 8.2 Environmental Reports For most properties in the Rouge Park Neighbourhood, the Pickering O[ficial Plan will require tLat an Environmental Report be submitted with any development applicadons (see sections 15.8, 15.9 and 15.11 of the Official Pian). a-i �oaoiwzoozi �o n��n.aa 8-1 v�eroo • 0 9 2 SECnonr 8 EMSP SUMMARY The Envlronmentni Rcport will precisely define thc devclopment limit on-sil�, anJ idcntify the appropriate edge management — buffers, building sctbacks, mitigalion, and rehabilitation (if nccessary). The Environmcnta! Report ahoulJ also idcntify any restoration opportunities to enhance conditions over what exists talay. The following descriUes the topics that Environmental Repons should address where developmcnt is proposed. The topics presented do not necessarily represent all clements rcquireJ in an Environmental Report but thc topics identificJ through the level of reconnaissance conducted for this study.

From a stormwater drainage perspective, the Rouge Park Neighbourhood consists of two distinct development azeas. The first development area is located to the east and sunounds Woodview Avenue while the second devclopment azca is located to the wcst and sunounds Altona Road and Finch Avenue. The following Technical Appendix provides technical detail of thc developmcnt of qualiry and quantiry requiremenis for the two development azcas in suppott of the Final EMSP Report. A.1 StormwaterManagement Guldellnes The Ministry of the Environment has defined water qualiry and quantity guidelines for stormwater managemcnt in the Stortnwater Managcment Practices Planning and Design Manual (MOE, 1994). The foilowing sub•sections highlight the water quantity and quality guidelines. A.2 WaterQusntltyGuldellnes For sub-watershed planning, the Collowing are general water quantiry guidelines: • If there is a potential for flood ha7ard immediately downstream of the proposed site, water quantity controls must bc implcmentcd. • If the development is locatcct in the lieadwater areas, the post developmcnt pcak flow rates should bc controllcd to pre-development levels. . If Uie development is IocatcJ in the lower reaches of the watcrshed cither no water quantity will be requircd or ovcr-convol would be required where there are ilooding concerns immediately Jownstrcam of the proposed dcvclopment. The proposed Rouge Pazk Neighbourhood is located within the headwaters of Pctticoat Creck and rcprescnts thc first urban area contributing stormwater flow. As such, Ihe second water quantity criteria applies to the area and post development peak flow rates must be conuolled to prc-development level. A.3 Water Qua!!ty Guidellnes As part of the Stormwater Management Practices Planning and Design Manual, extensive modelling of different end-of-pipe stormwater management facilities was undertaken including wet poads, dry ponds, infdtration systems, and wedands. Thc vtioo-ontss�im�mo.a� /1-1 Decemhr xl. 1999 oss APPEND/X A STORMWATER QUANT/TY AND QUAUTY CONTROL resulla of the modelling ulong with u relutionship betwcen temoval elfclencics and habitat protection allowecl stormwater management facility sizes to be recommended for difCerent imperviousness Icvels and level of habitat protection. A totai of four levels of habitat protection were specified including the following: • Level 1 protection is to be applied in fishin� spawning areas, esscntial fish rearing areas, highly praluctive Ceeding areas, rcfugcs, constrictcd migration routes, habitats supporting endangered or thrcatencd spccics, anJ groundwater recharge areas for coldwater strcams. • Level 2 protection is tu be applied for feeding areas, unspecialized spawning nreas, and in areas with extensive pool -riffle-nm complexes. •[.evel 3 protection is to be applicd for arcas that incluJe municipal drains, highly ultered watercourses and artificial drainage swales. • I.evel 4 protection is intcnded only for retrofit and re•developmcnt simations. Upon consideration of the recciving watcrs that will rcceive stormwater from the proposed Rouge Park Neighbourhood, Lcvcl 1 protection will be required. Although Petticoat Creek is not considered a coldwater stream, it has a direct mlationship to the Provincially Significant WGIanJs in tlic area, habitat, and thc grounJwater systcm. As such, as I'ctticoat Crcck is considcred to rcquirc Levcl 1 Protection.

An analysis of this sewer using a 5 year design storm determined that oNy 0.50 ha of the Rosebank area could be drained into this sewer. The rcmaining area will be drained by a storm sewer on Finch Avenue and into the Altona Road storm sewer system. The uttachecl design shcet for thc Rosebank Road storm sewer shows that the capacity of this eaisting storm sewer will not be cxceedeJ because of a 5 ycar storm with the addition of 0.50 ha to lhe overall drainagc area. To determine prc and post development flows, an XP-SWMM model of tl�e devclopment areas was developed. Thc model consisteJ of threc area nodes representing the dcvclopment arounJ Wooclview Avenuc, Altona Road and Rosebank Road. In keeping with thc fndings of the existing Rosebank RoaJ storm sewer analysis, thc Rosebank area consists of 0.50 ha of road arca while thc remaining developeJ arca in the vicinity of Rosebank RoaJ will drain towazJs Altona Road. Ma1cl inputs includcd catchmcnt arca, percent imperviousness, width and slope and infillration paramcters. Catchmcnt areas, wiJth and slopc were measured from maps of the arcas. Pcrccnt imperviousncss was calculatcd by assuming Ihat ali azens with thc cxccption of thc road arca arc pervious. Infiltration paramelcrs were selectecl based on soil types. Table A.2 ptesents the model parameters selected to represent prc-cicvclopment conditions. Tnble A.3 prescnts Ihc prc development tlows Jevcloped for the Uucc areas based on thc paramctcrs shown in Tabie A.2. Post development conditions wcrc defined using thc land usc pianning maps completed by the Town of Pickcring, To represent post dcvclopment conditions, modcl parameters were adjustcJ to rctlect more impecvious arca and shoner drainage routes. The following assumptions were used in the Jevelopment af post development model parameters: • All proposed road areas were azsumed to 90% imperviaus. , .

The proposed development will incrcasc cunoff volumes. Without adequatc stormwater management, the frequency and duration of erosive flows will increasc at downstream locadons along the creek. Continuing or aggravated erosion will result in degraded water qualiry, damage of aquadc habitat and possible saCety risks or property damage. B.1 Overvlew Staff of XCG Consultants met with staff of Toronto Rcgion Conservation Authoriry in early November to discuss Ihe approach to erosion impact analysis. !t was agreecl that use of a computer mafel to simulate streamtlow and erosion indices in Petticoat Creek downstream ns a far as Sheppard Avenue would be a suitable approach, It was agrccd that the QUALHYMO hydrologic modelling sotiware would be appropriate, and that computation of erosion indices using the technique dcscribed by MNR (1982) would be suitable. It was also agrced that erosivc indices shouid be based on long-tcrtn continuaus stmamflow simulation (as opposed to single "design event" simulation), recognizing that thc frequcncy and duration of smaller to moderate runoff cvenis can bc critical in terms of ongoing erosion, It was further agrecd that runoff moclelling parametcrs could be dcrived from Ihe OTfHYMO watershai model that had been earlier developed for Petticoat Creek by Cosburn Patterson Wardman Limited, as described in the 1993 report "Hydrotogy and Hydraulics Upclate for Mnin Petticoat Creek: Smge 1 Study of Comprehensive Stonnwatcr Managemcnt Stratcgy for Altona Porest Area" (Cosburn Patterson Wardman Limited, Dec,1993). On November 15, 1999, field staff canied out ground survcy of representative cross-section of thc crcek flow channcl and floodplain, and gathered samples of channcl bed and bank materials to allow Cor quantitative analysis of the erodibility of these materials. Subsequently, a QUAI.HYMO model was dcveloped to allow for continuous long- tem� stteamflow simulation and erosive index computadon. tldOT!-0111 2 99193 8 ta6memo.da" Deamber 11. 1999 B-t 108 i f APPENDIX B EROSION IMPACT ASSESSMENT AND CONTROL B.2 Watercourse Ground Survey Five watercoursc cross-scctions wcre surveycJ in dctail on November 15, 1999. The locations of the five cross-secdons are shown in Figurc B.1.

Flgure 8.1 LocaUons of Watercourse SecUons LocaOons of watercourse cross•sections surveyed November 15✓99. Allgnment of each secUon was marked using yellow survey stakes located at each end o/ each section. Thc level survey of the sections was based on using local bcnchmarks (as opposed to using established gcodetic vertical-control monuments, as none were conveniently located). Sections A, B anci C were surveyed relative to a benchmark set on a concrete headwall of a storm out[all pipe from Granby Court. For Sections D and E, the vertical benchmark was the top of a stake installed in the creek overbank area.

Plots of the resulting creek cross-scctions ate shown in Figures D.5 to D.9. All survey notes are on file with XCG Consultants Limited, B.3 WatercourseErodlbilityEvaluaHon At each of the five cross-sections, samplcs of channcl bank materials were taken from near the edge of water, as wcll as at locations roughly 0.3 to 0.6 mcters up the channel bank. Sufficient sample was gathered to allow for grain-size analysis (using sicve and/or hydrometer nnalysis) as well as Atterberg limits tests if Uie matcrial proved to be su(ficicntly cohesive. � 14 samples were gathered and submitted to Inspec-Sol Inc. (Kingston, Ontario) for the geotechnical analysis. None of the samples was found to have suffcient cohesiveness or swcture to warrant Atterberg limits testing. Crain-size nnalyscs were completccl using sieve analysis on 8 of 14 sunptes, and sieve/hydrometer analysis on the remaining 6 samples. Results are summariud below in Table II.1. Ta61e B.!

During sample collection, it was noted that there are significant vegetativo root binding effects within ihe channel bank soil profilc; the eFfect of vegetative cover and associated root systems likely plays a significant role in conuolling crosion of channcl banks. B.4 Deve/opment of St�amBow Simulafor Computer modelling soCtware (QUALHYMO) was used to develop a stceamllow simulation moclel for Petticoat Creek downstream to about 150 meters bclow Sheppard Avenue (at the location of survey Section E). The model considers the enlire watershed and uses accepted hydrologic principlcs and techniques lo compute runoff volumes and stream discharge in response to precipitation dala supplied to thc mocfcl. The model was created by subdividing thc watershed into a number of subcatchments. This was done Cor the present-clay (1999) conditions as wcll as Uie proposed future condition in which thc Rouge Park Neighbourhoal is Cully dcvclopcd undcr Concept '�". Tablc B.2 lists thc subcatchments for tl�e existing anJ fulure conditions, respectively. Thc QUALfIYMO mocici operatcs by simulating thc outtlow Gom cach subcatchment, and thcn routes and adds ihe subcatchment tlows as shown in the connectivity diagrams shown in Figures 8.10 and B.11. The tesuit is simulatecl streamflow at various locatioru along Petticoat Creek. Thc modcl includes cxplicit rcprescntalion oF thc existing SWM pond (stormwatcr trcatment pond) locatcd just north of thc CNR rail line and just east of Autumn Drive. lnformation on the characteristics of this ponJ werc obtained from a report entiqed "Storn�watcr managcmenl Pond Design Bricf, Dramalea Highbush Sutxlivision 18T-88074" prcparcJ by Cosburn Yattcrson Wardman Limited, July 1994. The QUALHYMO model developed for diis project was partly based on a previous hydrologic moclel documented in thc 1993 rcport "Hydrology and liydraulics Upclate fot Main Pcuicoat Crcek: Stage i Study of Comprehensive Stormwater Management Strategy for Altona Forest Area" (Cosburn Patterson Wardman Limited, Dec 1993). Given that there is no known streamflow data for Petticoat Creek, direct calibration and verification of the moclel were not possible. To select model paramctcrs reference was maJc to the early QUALFIYMO model developed by CPWL. As such, sclected maielling parametcrs (e.g. unit-hydrograph times to peak, infiltration parameters) for the QUALHYMO watershed model were made consistent with lhe earlier CPN1L model. As a result, the QUALHYMO model U-1077-01\129919J8 �ecMxmo.doe , B� Deeember 71.

It was determined that without stormwater managcment, the modcl estimatcs that 5- year peak tlow in Petticoat Creek at the CNR will increase by about IS%, and avent runoff volume will 3ncreaze by about 4%. B.5 Selected Slmulatlon Intervals for Eroslve Ana/ysls Streambank erosion rates will depend on the frcquency, magnitudc anJ duration of critical erosive flows. It is therefore important to cxamine impacts by considering the net ef(ect of changes in walershed hydrology over the course of a number of cunoff evcnts (as opposed to considering imQacls during only sciccted "dcsign" evcnts such as 2-year or 5-year cvcnt). The QUALHYMO malel was initially uscd to simulate the May-October perial of 10 years, 1979 to 1988, using continuous records of hourly prccipitation for the Greater Toronro arca. Thc resulting continuous simulated sveamllow resul►s werc revicwed in conjunction with thc prccipitation data to select a single six-month interval (May 1 to Oct 31) that could be considered as a suitable "test periocl" for cxamining crosivc impacts and for analyzing mitigatic:n rcquirements.

Along U�e main cl�anncl at a location alongsidc tlie northeast corner of Granby Court (approximalcly 300 m upstrcam of thc twin culvcrts at the CNR tracks).

This methodology rcquires the estimation of critical tractivc shcar stress for creek bed and banks. Using Ute empirical data presentcd in thc 1982 MNR report and the resulis of the grain-size analysis of channcl bank materials, it was judged reasonable to use the following cstimates of critical tractive shear stress: . 5 Pa for channcl bank materials located 0.0 to 0.3 m above channel bottom. u-tanAn�:�vime ��.a,� B-7 Decem6er ]I. 1999 ' � 114 APPEND/X 8 EROSION IMPACT ASSESSMENTAND CONTROL • 6 to 10 Pa for chazmel bank matcrlais situatccl 0.3 to 0.6 m abovc channel bottom. . 15 to 30 Pa for channel bank materials situatcd 0.6 m or morc above channel bottotn. The increaze in criticai stress with height abovc channel bottom was intendeJ to representthc e[fects of vegctative cover and root binding thatincrease up the height of channel banks. The channel becl was estimated to have a critical crosive stress of over 100 Pa based on the consistent presence of a stable cobble bed along the cBannel that providcs energy dissipation and high resistance to bcd scour. The simulated streamtlows for May 1 to Oct. 31, 1981 were then used to compute crosion index values (i.e. cumulative excess shcat stress) at regular intcrvals of 0.025 m ovcr the height of thc channcl banks. Initial runs werc carricd out for the existing condition, as well as the futurc condition without stormwater management controls in place. This alloweJ for somc cxamination of the potential uncontrolled impact of the proposcd devclopmcnt. Modelling resuits for the perial show that at the creck location below Sheppard Avenue, thc crosivc impulsc could incrcasc by 409b to over 20�o at dcpths above channcl bottom of 03 to 0.6 metres, if lhcrc is no srormwatcr managcment for thc proposed dcvelopmcnt.

To nllow this analysis lo proceed, i! was necessary lo makc somo modclling assumptions about wherc storniwatcr dctention might be provided. The following assumptions werc made: .

The approach aJopted providcs a planning level undetstanding of the arca watcr budget highlighting design feawrrs that are to be considered in the development of any parcel. The proposcd urban development in 1he Finch/Woalvicw Avenue ama is likely to have some impacts on the local groundwater system and somc resulting elfects on the hydrology and waler supply of the adjacent wetland complex. Given that the proposed developmenis are to be serviced by "canventional" storm sewer systems, the proposed development miqht have the (oilowing implications for thc local groundwatcr system: . Rcduced infiltration ot water through the soil profile to thc water table, duc to diversion of hard-surfacc nmoff dircctly into storm sewers, as well as improveJ grading ancl drainage of vegetateJ areas. . Reduced contribution to the water table duc to intcrccption of infiltrated water by building foundation drains. . ReduceJ permcability of surface soil horizons duc to soil compaction that lakes placc during �:ie cicaring, grading and conswction of roadways and buildings. C.1 Analysls Approach To examine the net impact on the wetland complex, two upproaches can be consiJered: . Water budgct analysis for thc cntirc wctlanJ complcx, which is bascd on quantifying watcr inputs Gom all sourccs to thc wctland, including the proposcd dcvclopmcnt zoncs. . Water budget analysis for the dcvelopmcnt propertics thcroselvcs, to providc cstimatcs of d�c changc in watcr budget componcnts (c.g. surfacc runo(f, watcr table rccharge) ►hat occur over the property area as land use changes from curcent wnditions to proposecl urban dcvelopmcnt. The first approach would require a regional unclerstanding of groundwaler systems and surface watcr sourccs Cecding the wetland compicx. This would likciy only show that the proposed development would have marginal impact on thc overall watcr budgct for the wcUancl, (presuming that the total development arca of about 40 ha direcqy atfects only a relative small portion of thc grounciwater system supplying ehe wctland). The second approach is more useCul sincc it quantifies the local impact of land developmcnt and drainage system installation over the dcvelopmcnt arca itself, and U•I 106U11129 9 197 9 uclwemo.doe �-� yieioo 127 APPEND/X C GROUNDWATER MANAGEMENT does not rciy on accurnle or deWilcd uncierstancling of larger-scalc grounJwatcr systems. This "local" approach has been used to estimate nct annual contribution to the watcr table over the proposed development arca by carrying out annuat water budget calculations using meteorological data for ihe GTA. For any time intervai, the water budget calculates an estimate of contribution to grounJwater as follows: C.1.1 Loca/WaterBudgetApproach Over any land arca, the nct annual contribution to U�e water table can be cstimated by carrying out annual watcr budget calculations using appropriatc mctcorological data. For any time interval, the water budget calculates an estimate of contribution to groundwatcr as follows: Cantriburron to groundwater = Preciptlation - Evuporransplrutlon Jran ��egetated areas - E�wporation jram hard surjaces - Dircu surface runop'jrom vegetated areas - Direcr surface runofjjrom hard surfares - Chnnge in soil ivater smroge Hcre, thc tertn "soil walcr storagc" rcfcrs to thc water stored in surCace soil horizons subject to evapotrenspiration losses. For annual water budgct calculations for a typical or averagc ycar, the changc in soil watcr storage is taken to be uro (i.c. soii water storage is samc at thc end of the ycar as it was at the start). 7'his allows esthnation of annual contribulion to groundwater bas�:d on cstimalcs o! cva�wtranspiration and dircct surfacc runoff. To allow cslimation of annual watcr buJget ovcr devclopmcnt zones in the proposcd Pickcring Rougc Park Ncighbourhood, thc following information sourccs and nssumptions havc bccn usecl: • Prccipitation valucs I�ave txen bascd on i�ng-term averages for thc Toronto arca, az published by E�vironmcnt Canada • Evapotranspiration losscs Gom vcgctaled arcas have bccn based on estimalcs dcvcloped by Enviro►uncnt Canada using metcorological data from Toronto International Aiqwrt. These estimatcs are pmscnted and czplained by Phillips (1976). Valucs for assumed soii watcr holding capacity of 200 mm were used as most suitabie for the sandy loam soils that characterize the study area. • Sudace evaporation losses Crom impervious surfaces has becn estimaled at 100 mm per year bazed on QUALHYMO simulation rcsults which were based on using potentiat evaporation rate data from Environmcnt Canada. The UJI00-0IU2991979 tecturcmo.Joc C.2 vieroo 1`�$ APPEND/X C GROUNDWATER MANAGEMENT QUALFIYMO simulation results account for th: fact Uu�t total annual hard- surface evaporadon is a function of both potential evaporation rate ancl duration that surfaces are wcttcd by precipitation. • Surface runoff volumes for existing vegetateJ areas on the proposcJ development propenies have bcen estimated at 5� of annual precipitation volumc. This was felt to be a reasonable estimate Cor undevelopal propcnics in the study arca that are characlerized by high soil infiltration, generally poorly definccl surface drainagc and heavy vcgetative cover. • Surface runoff from impervious arcas has been computcJ as total precipitation less direct evaporativc losses. • Surface runoff Crom vegetatcd areas within urban developmcnt areas (i.e. I.awns, residential yarJs, park areas) has bcen estimated at 15% of annual prccipitation. This assumption is intended to rcflcct the cffects of improved grading and other urban landscaping and drainage fcawres ll�at tend to promote efficient surface drainage. On this basis, annual water budget catculations have been made for existing and proposed conditions over proposcd devclopmcnl propertics. '1'hcsc resul�s shown in Tablc C.1 show thc patcntially dramatic reductiun in grounJwatcr wntribution that can resuit from urbaniration. C.2 OpportunityforMitigation Thc atwve results also show that nct watcr yicld will incrcasc wiUi urbanization. This is largcly duc to raluctions in eva�wtranspiration and increases in surlace runoff. This incrcascd yicld prescnts thc opponunity to mitigatc thc impact on groundwatcr contribution by infiitrating a ponion of thc incrcascd surfacc runoff volumc. On new development sites, infiltration of hard•surface runo(f can be accomplished in various ways incluJing: • 8ngi�mcrcd infiltration facilitics in which runoff is collcctcJ, prc-trcatcd anJ thcn allowed to infillratc into the nalive soil profilc. Siting of such facilitics rcquires goal understanciing of local groundwater systems, ilow patlerns and scasonal water-tabic cicvation tlucwations if the systcros are to perform as intendecf. �•uoao�u:v��mv m�ro,.�e G3 v�eiao 129 APPEND/X C GROUNDWATER MANAGEMENT Table C.!

These calculations provided resuits such as the following: Tab/e G.2 GroundwaterMitlnation Ur600f:ed l0 0.SR Urbanized to 45R Impervtousnas impervtomness xtth no 6ard- wllh SO% of 6ard-surface runo(f surfacerunoftln(i�tnted inlillraled Amuil Precipiu�K�n GTA gpp n�m g�p ����n EvTr from vegebuJ aas 260 mm 280 mm Gv��r�lion frum furd wrfxes SO mm SO nun Dira� runuff frum IurJ surfaca RO nun 160 mm Uira� runu(f from vr�euieJ ueas ��i��i� qp ���m Nn con�ribuiiun w W��er �ble YU mm 22U mm Thc waler budgcl calculations show that groundwaicr comribuliuns can bc maintainrcl al cxisting Icvcls if a substantiat �wnion of harJ-surfacc runoff is allowcd lo infillratc ovcr vcgctated arcas.

Nonetheless, the results demo�ssuatc that arca-wide watcr tablc contribution can be maintainal if roughly SO% of hard•surfacc runoff is given the opportuniry to intiitrate ovcr vegetateJ arcas. C.3 Recommended Approach The hani surfaces include all roads, parking arcas, sidewaiks, driveways and rewflops. In general, cunoff from road and parking surfaces can bc expected to be contaminatcd and carry sediment loads that make it unsuitablc for infillration unless first lrcatcd. In any evcnt, runoff from those surfaccs will be collectcd via catclibasins to the storm sewcr systcm, resulting is no opportunity to infiltratc this portion of sitc runoft unlcss enginecrcJ end-of-pipc facilitics arc useJ. What rcmaina is thc opportunity to take roof Jrainagc and infiltratc it. In typi�al urban development, rcsidential or commercial, rcwf areas lypieal account for 40% to 70% of impervious arca. Thereforc, the rw! drainagc alone can mcct the infiltration volume targct identified above. On this basis, it is rccommendcJ that urban dcvclopmcnt dcsign for thc wcstcrn portion of thc Jcvclopment arca (Arras 1, 5 and G in tlic rinch/Woodvicw arca) should bc bascJ on dcsigning sitc Jrainagc such that 1. A minimum of 50'� of roof Jrainage is divcncd onlo vcgctalcd arcas in n way ihat prumotes Jistribuled infiltration. 7'he could inctudc thc usc of splash paJs, sidc-yard atxl n:ar•yard swales anJ othcr grading mcasures lo promotc infiltration whilc also maintaining expcct�Kl Icvcis of scrvicc (i.c. avoiding nuisancc poncfing a�xl prolong��J wctness in rcar y�rds). 2. Usc of catchbasins to coilect rcar-yard drainagc and divcrt it into tlre storm scwer systcro should bc avoiJcJ as mucli as �wssibic. Instcad, lot graJing should allow for cxccss lot runoff to drain onto cJgc trcalment amas arxl into lhc wctlanJ arcas adjaccnl to thc dcvclopmcnt zone. I'or lots that arc not situatcd adjacent to a wctlancl eJgc•trcatmcnt zonc, use of grasseJ sidc•yard arnl r;.u-yard swalcs should bc useJ as mucli as possiblc to convey lot tunoff to ncarby cJgc-trcaunent areas. 3. For cach individual property dcvclopmcnt, thc Town should rcquim thac thc dcvcloper providc detailcd sile Jrainagc plans and supporting watcr buJget calculations that demonstrate that present-day contributions to the water tablc will be maintainal in future, through measures such as those outlineci above. The water budget calculations should consider seasonai variations. �I100-011119919J9 �eclunemo.doe `.� viuw 13 2 APPEND/X C GROUNDWATER MANAQEMENT Conaldan0ons Regaid/ng Bu!lding FoundaUon Dralna Thc recommeaded approach in which roof water is draincd onto grassccl azcas wiil, as Ihe water budget calculations show, maintain wlu�t has becn termul "nce annual contribution to proundwatcr". This tcrm rcfcrs to the volumc of watcr that vcrticaily drains tluough the soil profile to waler-bcaring zones U�at arc dceper than tt�osc subjectecf to evapotranspiration losses. In oUier worJs, die nct contribution to grounclwater has been compuled as the amount ot watcr that will drain to below the root zonc. Within an uPoan Jcvclopment arca, builJing Coundation drainc wiil intcrccpt somc of this water. The wrrcnt design approach is that foundation drains autict to the storm sewcr syslem, which ultimately drains to nawral watercourscs such as Petticoat Cr��ck. Picld invcstigations along Pctticoat Crcck in 1999 dcarly showcd that crcek bascilow was being fcJ by dry-wcather outflows Gom urban storni outfalls, and U�e sourcc of Ihis dry-wcalher sewcr Ilow is likcly panly or mostly fowxlation drainage. In areas adjaccnt w protecteJ weUanJs, qie nct effcct of foundation drains may bc to diven grou►xlwaler away from the wctland. �oundation drains can potentially cause significant lowering of local watcr table.

E 141 Rouge Park Neighbourhood Development Guidelines N1.1 Genere) Description The Rouge Park Neighbourhood is located along the west side of Pickering, at the northern limit of the Ciry's South Urban Area. It comprises an area of approximately 160 hectares. The Neighbourhood is bourtded on the west by the Pickering-Toronto boundary, on the north by the Inlerprovincial PlpelineJC. P. Rail Ilne, on the south by the Ontario Hydro Gat(neau Corridor, �nd on the east by open space lands just east of Rosebank Road. The Neighbourhood includes part of the Rouge Park, and has significant open space lands associated with the Petticoat Creek valley, wetlands, and various wooded areas. The Official Plan designales lhese lands as 'Open Space Syslem - Naturel Area'. All lands wilh the 'Natural Area' designation, as well as 'Freeways and Ma(or Util(ties — Potential Multi-Use Areas' (the Ontario Hydro Gatineau Conidor), are also designated as the'RougrOuffins Wildlife Corridor'. Additional information regarding environmental (eatures and stormwater management is available in the Rouge Park Nefghbourhood Environmenlal Master Servicing Plan (see seclion N1.4 of these Guidelines). . The developabie lands within ihe Neighbourhood are designated 'Urban Residenlial Areas - Low Density', as well as 'Mixed Use Area - Local Node' at the south-east corner of Finch Avenue and Allona Road. Developable lands comprise approximately 2596 0! the total Ne(ghbourhood area. N1.2 Development Gaals Developable areas within the Rouge Park Nefghbourhood comprise many small propertics, some oI which are irregularly shaped. The challenge in developing/redeveloping ihe Neighbourhood is overcoming this Gagmenled ownership, w ihal Ihe resullfng impression is lhat of a cohesive, well-desfgned neighbourhood. In order to accomplish this, ihe Rouge Park Neighbourhood Development Guidelines establfsh the following broad goals: Goal I: Finch Avenue will serve as the backbone o/ the Neighbourhood. Development adjacent lo Ihis primary road should establish a slrong visual and physical relationshfp with the street, a relalionship which is evident through thc Ncighbourhood. Goa12: Development must maintain a connectlon wieh surrounding nalura! areas. The greatest attribute and most idenUOable aspect o(lhis Neighbourhood (s the variety and number o( natural areas, valleys and open space lands. Neighbourhood design within developable areas must be done in a manner that retains visual and physical (where appropriate) connecUons lo these areas. This can be accomplished through caretul design and placement o( internal roads and walkways, and siting of buildtngs. Rouge Park Nefghbourhood Development Guldelines Page 2 142 Coal 3: 7he intersection of Flnch Avenue and Alcona Road will be fhe cenbal /ocus o/ the Neigh6ourhood.

N1.3 TertiaryPlan Figure A presents a Tertiary Plan that illuslrates many of the design objectives discussed in lhe (ollowing text. The location oF the various symbols on ►he Tertiary Plan should not be considered absolule, as they will be refined through the review and approval of development applications. N1.4 Environmental Master Servicing Plan City Council has endorsed an EnvironmenWl Master Servicing Plan (or the Rouge Park Neighbourhood (EMSP). The EMSP is a companion document to these Development Guidelines, and provides direcUon on stormwater management and strategies (or developing in a environmentally responsfble manner, Slaf( and Council will refer to the EMSP when considering development applications wilhin the Neighbourhood. Landowners and developers must refer lo ihe EMSP when designing and undertaking development. N1.5 Rouge Park Managemenl Plan A portion of the Rouge Park occupies much o( lhe western Ihird of the Neighbourhood. The Pickering O(ficial Plan contains policies that deal specifically with the Park. Section 10.16 of the Plan establishes general resource management policies for supporting the goals of the Rouge Park Management Plan, and s�rlion 11.16 requires that new development in lhe Rouge Park Neighbourhood have regard for Ihc Managemenl Plan. N1.6 Rouge�Dufrns �Idli(r Corridor Managemenf Plan Iniliafive A Management Plan should be prepared for ihe Roug�Du(fins Wildlife Corridor, which would address preservation, maintenance and restoretion of the Corridor. SWkeholders such as lhe Ministry o( Nalural Resources, Toronlo & Region ConservaUon Authority, Region of Durham, City of Pickering, Canadian Paciflc Railway, Interprovincial Pipelines, and Onlario Hydro Services are encouraged to come together and (orge a partnership to support the future of ihe Wildlife Corridor. Owners of lands within the Wildli(e Corridor should be requfred to operate and undertake works wilhin the parameters established by a Rouge-Duffins Wildli(e Corridor Management Plan. Rouge Park Neighbourhood Development Guidelinet Page 3 N1.7 Servicing N1.7.1 StormwaterManagement . 143 The Tertiary Plan identifies Ihe preferred IocaUon of two stormwater management ponds. Lands west of Petticoat Creek would contrfbute to a pond located on Onlario Hydro lands on the east side of Woodview Avenue. Lands east of Petticoat Creek would canlrlbutc to a pond located on Ontarfo Hydro lands on Ihe west side of Altona Road. Detailed siling, engineering and greding plans are required prior to finalization of lhe sites — reference should be made to the Environmencal Master Servicing Plan for addiUonal stormwater management details. As discussed tn the Environmental Master Servicing Plan, lhere may be a Iimited opportunity for some lands at the north-west comer of Finch Avenue and Rosebank Road to draln lo an existing storm sewer along Rosebank Road. ' N1.7.2 SanitarvSeweraue The existing main sewcr Unes are laated along Woodvlew Avenue near Sandhurst Crescent, as well as along Allona Road at Pinegrove Avenue. The extension of sanitary sewers into the Neighbourhood will be required prior lo development occurring. The sewer along Woodview will serve the area west o( Petticoat Creek. It will require minor upgrades prior to exlenslon, and has capacity to accommodate approximalely 500 additional people. The sewer along Altona can serve the remainder of the Neighbourhood. With minor improvements, (t can accommodate approximately 1,700 additional people. It may be possible to service a Itmited amount o( land west ot Rosebank Road via a sanitary sewer which exists on Rosebank, soulh of Finch Avenue. Such a possibiliry can be examined (urther ance detailed development appliwtions are submilled (or the arca. The City will support this servicing arrangemeni provided Ihat ft is acceptable to the Regian ol Durham, and does not require substanlial regrading o( ihe subject lands which may inapproprialely impact surrounding propertfes. An altemate means of providing sanilary sewerege to certain areas (particularly those on the north side of Finch Avenue, west oI Petticoat Creek) is a direct connection to the York•Durham Trunk Sewer via a pumping station/(orcemain. The City will support this serv(cing arrangement, provided that the pumping station/forcemain is privalcly owned and operaled, or othenvise agreed to by lhe Region, N1.7.3 WaterSuuolv The majority of homes within lhe Neighbourhood are currently scrved by the Regional water supply system, which includes watermains installed along Finch and Woodview Avenues. With the recenlly completed expansion of the Ajax Water Supply Plant, there are no constraints on the system's ability to accommodate planned growth in this area. No facilities other than the exte�sion of watermains are required. ;� ' _ ��.� . v4 , '.. �. . . ., .. ...; ' .. .�.. . :, . .,�. . � . _ � . -�I'.lF �� . . . . . . . ' � . Rouge Park Neighbourhood Development Guidelines Page 4 14 �1.7 4 Servicjpg Other Lands Within the Rouge Park Neighbourhood, a few existfng homes are situated oulsfde of developable areas (there are several on Finch Avenue west ot Woodview Avenue). As lands in 1he vicin(ty ot such homes are developed, Ihe Regton is encouraged to make available water and sanitary sewe�age to exist(ng homes. N1.8 Neighbourhood Population Targeta The Official Plan establishes a population Wrget for lhe Rouge Park Neighbourhood of 1,600 people. Based solely on sanitary sewer capaciry, a population Wrget of 2,200 people is achievable (500 west of Petticoat Creek, and 1,700 east o( the creek). However, i( the population were to grow much beyond 1,600 people, the Durham District School Board has fndiwted lhal an elementary uhool site would be required within the Neighbourhood. In order to minim(ze the need for public facilities in lhis area of Umited developable lands, a population Wrget ot 1,600 people will be retained, with a maximum oi 500 people on lands developed west of Petticoat Creek which cbnUibute to the Woodview Aienue saniWry sewer. At Cuuncil's discretion, the population Wrget may be exceeded if the City, in consulWtion with the Durham District 5choal Board, is saHsfied that existing development, or proposed development, does not generate the need (or additional school facilities within the Neighbourhood (which would be in addition lo lhe site required by the Durham Catholic Dislrid School Board, see section N1.9.5). The populalfon target o( 500 people west o( Petlicoat Creek may be exceeded if ihe Cily and Region are ulisfied ihat alternative servici�g arrangemenis are fcasible and appropriate. This may include a dtrect connection to Ilie York-Durham Trunk Sewer via a privately owned and operated sewage pumping taciliry. r � Rouge Park Nefghbourhood Development Guidelines p�$e 5 N1.9 Devdopment Standard� N1.9J DevelonabieArca� 145 The TeAlary Plan (ncludes a delineation ot'developable areas' within the Neighbourhood. The delineation fs based on the exclus(on of sensit(ve natural teatures such as wetiands, woodlots and stream rnrridoa. Functions associated wtth ihose features may depend on lands adjacent to the features and thus, wme resvfctfons may be placed on the adjacent lands within the develop�3ble areas cunently identified. The precise relationshfp between features and functions for specif(c areas will be determined wlien development is proposed tor that area, through the submission of an EnvironmenWl Report (see section 15.11 of Ihe Pickering O(ficial Plan). The Environmental Report will be required to, among other matters, precisely define the Umits of development and identify appropriate edge management strategies which may include bu(fers, restoration zones, and building setbacks. The Environmenlal Master Servicing Plan provides direction on undenaking this work for various areas within the Neighbourhood. Where apprapriate, the conveyance of signi(icant environmen4J (ealures and their bu((ers to the City or other public agency may be required as conditions o( development approval. �: I I II • �� �`'�'�''r' , f,., � ' , ,�.�-; sl� •�`;`' ��4y ''� �,, . � �'�'��,'•'.)i,•�� ��/ s 1� �� • � �y� �:,;�;tii'%�:>1K;x �'4 ��', �� „i �: �, r 'q Ak'i � i 'K,; i•.�i i �1 /�`,'4• �ft � �l-'= _,i�i�l���`��J�c���!.'�i�.M Gross-sectlon o!a typical edge management sUategy At the time of Council approval of these Development Guidelines, the lands on the noAh side o( Finch Avenue, opposile Woodview Avenue, were subjed to a development appllcaHon and appeal of Ihe Pickering Official Plan. The 'dashed' Itne identified on the Tertlary Plan for this area indicates that development limils have yet to be determined. This will be accompllshed through Ihe review of the development application, and resolulion of the Official Plan appeals. 146 Rouge Park Neighbourhood Development Guidelines Page 6 N1.9.2 Transoortation Network Exlst(ng Roads The two primary roads in the Netghbourhood are Finch Avenue and Altona Road, which are both artcrial roads that perform an important Ua(fic function in the City. As lands are developed along these roads, lhis (unclion must be mainWi�ed. Accordingiy, the number and spacing of new access points lo Finch and Allona will be carefully reviewed by C(ty and Regional staf(. However, with the Cily's interest in Finch Avenue serving as the Neighbourhoai's 'backbone', access restriclions to Finch will be less stringent compated with Altona Road. It is anticipated Ihat Finch Avenue and Allona Road will be widened to four lanes in Ihe future, and upgraded to standard urban cross-sections wilh curbs, gutters and sidewalks. At ihe time of improvemenls to Finch Avenue, the Finch/Rosebank Road inlersedion will be realigned. it is also anticipated that new signalized intersections will acur along Finch Avenue at Rosebank Road, and at Woodview Avenue. As modificaUons to Finch Avenue, Allona Road, and Rosebank Road are made, impacts on the area's natura) features and functions, and abutting propeAies, should be minimized and opportunities to maintain/enhance natural features and fundions should be pursued. SWndard engineering and construction techniques may not be appropriate. Innovative and environmentally-responsible techniques such as Ihe following may be required: ■ eslablish right�of•way widths that are consistent with the required number of lanes, rather than securing ihe maximum permissible widths; • shade slreet lights and other amblent lighting away from nearby woodlots; • minimizc alteralions to exisling grades and drainage paticrns; • minimize loss of existing vegetation; and • provide culverts and olher roadtrossing opportunilies for herpetovores and small mammals. As set out in section 11.16(c) of the Official Plan, Cily Council will support improvements lo lhe level crossings of the C.P. rail Iine at Ihe Scarborough•Pickering Townline Road, Allona Road, and Rosebank Road, such as the (nstallation o( appropriate safely measures including automatic safety gales, and gredc separations where appropriatc. Futurc Roads The Tertiary Plan identifies Ihe approximatc alignment of fulure principal roads wilhin the developable areas, These principal roads (in addition to other future roads Ihat may be required for some areas), are required to create permeable development pockets, and (acilitale an e(ficient movement of pedestrians, private vehicles, iransil, and service vehicles through the Neighbourhood. The TeAiary Plan also identifies'additional access locations' along Finch Avenue and Altona Road. These locations will provide access to smali and/or irregularly shaped areas that may be better served by private roads rather than more landtonsumptive public roads. Alternate, additional and temporary access pofnts must be approved by ihe City and Region of Durham, Altemative development standards such as reduced right-of•ways and privale rear lanes will also be considered. Rouge Park Neighbourhood Development Guidelines FaBe 1 147 A potenttal •through-road' between Finch and Allona fs fdentified (or the south-east corner o( thc two sireets. This conneclion is pre(erced if the lands redevclop primarily as one block. However, if exisling homes on the south side of Finch are reWined ihrough redevelopment, the through-road (although desfrablel will not be required (see sectio� N1.9.3). Cohesive Street Deslgn As new public roads and (mprovements to existing roads are designed, the outcome should be a public road netwark that presents a dis►inct character for the Neighbourhood. This would include a uni(ied approach ta: • street tree species; • boulevard and median landscaping, particularly at the Finch/Altona intersection; � demarcation of pedestrian crossings . • style o( street lights; and ■ placement o( slreet (umiwre. In addition, the style of street lights and selection of street trees and landscaping materials should enhance environmenWl (eatures and functions in Ihe Neighbourhood. SJdewalks Sidewalks will be required on at least one slde of all new public roads. For condominium developmenls, a palhway syslem should provide convenient pedestrian access to appropriale areas within Ihe sile, as well as connections to public sidewalks and streets. Trail System The City o( Pickering Trails and Bikeway Master Plan idenlifies a nelwork o( o(f and on-road trails throughout urban and rural Pickering for such users as pcYlestrians, joggers, cyclists, in-line skaters, cross-country skiers, etc. Over lime, key recommendalions of the Master Plan will be implemented to achieve lhe City's vision af a multi-modal community, The Master Plan identi(ies several conceptual trail routes Ihroug�; the Neighbaurhood. Un-road '(uture bikc routes' are identified along Altona Road, Finch Avenuc and the Townline Road. O(f- street trails include a'future hiking trail' along Pelticoat Creek (likely on the east side of Ihe creek), and '(uture multi-use pathways' within the Hydro corridor and aloiig lhe York•Durham Trunk Sewer. The Tertiary Plan identifies polential trail access locations that will Ifnk new development with these trafl syslems. Opportunities lo secure adequale right-of•way for these future trail systems, as well as links lo Ihe Neighbourhood, will be considcred in the revicw of subdivision and site designs, as the area develops. Prior to Ihe construction of any trails, detailed assessments o( trail localions and alignments will be required. Design of improvemenls to Finch Avenue and Allona Road should accommodate space within the right�of-way for bicycle lanes, as per the Trails and Bikeway Master Plan. r Rouge Park Neighbourhood Development Cuidelines Page 8 148 N1.9.3 � Devclopment Along Finch Avenue andAltona Road Finch Avenue ts expected to mainWin (ts role as the key street or'backbone' of the community. This may fnvolve a conlinuatiun o( the historic development pattern along Finch — that of homes and other buildings facing the street. New development along Finch Avenue and Altona Road should employ innovalive architectural and urban design lechniques to humanize the street, mitigate ihe effecls of traffic, and present an attreclivc frontage along these roads. Oevelopment with reverse fronWges and noise altenuation devices such as significant fencing and earih berms is slrongly discoureged. Appropriate design treatmenls could include the use of: • singlrloaded service roads: • homes orienled lowards Finch and/or Altona, and accessed via private rear lanes; • sofl landscaping Ireatments Itrees, shrubs, hedges, etc.) which help define street and property edges, while also providing limited sound absorplive qualities; • enhanced flankage elevations fealuring ample glazing, enlrances and archilectural detailing; and • multi-Ooor builJings siled close to existing strcels, thereby using iheir building mass as a separator between the roaJ and rear amenily arcas. Altona Road wil� likely experience a higher rale of traffic growlh than Finch Avenue. Allhough use of Ihe above desiqn treatments is also encouraged for Altona Road, limiled use of noise attenualion devices may be permissiblc. Potentiallor Rear-Lot Devclopment As mentioned previously, development paltems along Finch Avenue have historically (ealured buildings that face the sireet. This includes several existing homes fronting Ihe south side of Finch just east o( Allona Road, and the norlh side n( Finch immediately east o( the Regional Waler Tower. The properties on which ihese homes are situated are o( sufficient depth to accommodate rear-lot development, which would allow for redevelopment of the surrounding �ands while retaining existing homes, This wili only be pradical however, if landowners are unifled in their approach to redevelopment of the lands — either all homes arc retained, or the entire block is redeveloped. A coordinated plan will be required for these blaks upon submission o( the first major development applications in these areas. I( existing homes are reWined, abutting development should be of a compatible scale and cha�acter, with particular attention to lot Gontage and build(ng heighls, as well as Gont, side and rear yards. Rouge Park Neighbourhood Development Guidelines Pa6e 9 Development Along New Roads As discusxd in seclion Nt.9.2, a nelwork ot public and/or privale roads will be required within the developable areas to provide (w permcabSlity and 10 faciliwte e(ficient vehicular and pedesUian circulation. For groundoriented dwellings (detached, semkietached, townhomes etc.), attention to a dwelling's relationship with the street is important. Accorclingly, Iheir design should coosider the (ollowing principals: 14� Principal I: Homes should featurc prominent main entrances that are easily identifia6le and visi6le (rom the street. A prominent entry point provides a focal point forthe home and fosters a sense o( warmth and human habitation. Highly visible entrances support informal surveillance along a street, thereby reducing potential for vanJalism and crime. Principal 2: Homes should provide windows and doorways at tlie front lace of the house to provide 'eyes on the stmet'. Windows 'open Ihe home', which fostcrs a sense of warmth and human habitation and providc opporlunities for living space (e.g. family room / kilchens) to be drawn to the front u( a dwelling. This arcangemenl of internal space maximizes oppoAunities (or in(ormal surveillance o( yard and street Gom within a home. Principal 3: Homes should o(fer an amenity area that accommodales opportunity for street-side lntcraction. An amen(ty area cauld be a front yard, landscaped area, porch, veranJah, etc. Providing Ihis space enhances oppoAunities to socialize with neighbours — this social interection can strengthen a sense of communiry within a neighlx�urhoal. Reduced building setbacks can draw ameniry areas closer together. Principal 4: A garage should be scaled and integrated wiefi the design of a house such that it is not the dominant aspect o/ ehe home. The width and projection of a garage should be sensitive to Ihe over-all xale of the house. The garage could be c!c�ached and piaced in rear or side yard. The use of shared driveways can increase the percenWge of a front yard available (or landscaping. Common underground parking areas could �e used for multi-unit grade related housing. Rouge Park Neighbourhoad Development Guidelines Page 10 150 N1.9.4 Neig�ourhaodCentre Building Focus Develapment around the intersection ot Fnch Avenue and Altona Road will be the 'heart' of the Neig��bourhood, both i� appeaiance and funuion. The use of appropriate building heights, massing, architectural (eatures and landscaping will establish a(ocal point at lhis interseUion. The Tertiary Plan identifies a'neighbourhood focus' at thc four rnmers of lhe interseclion, which require a slrong presence al Finch and Altona Io define Ihe area as a centrc. Thfs wn be accomplished by buildinp, close to the stree�, providing ouldoor public space (squues, plazas), and the use of hard and soh landscaping. Parking areas should be organized such lhat the majoriC� of the area does not separate principal buildings from Finch /lvenue. Architecturally significant structures that relate to the buill heritage of this area are encouragecl. This would include use o( similar architectural styles and building materials.

Typically, the tallest buildings will be comparable in height to that of a malure Iree canopy — 4 l0 5 storics. local N� le The south-east corner ot Finch Avenue and Altona Road is designaled 'Mixed Use Area - Local Node• in the O(ficial Plan. This designation provides for a broad range of uses, including: medium density residential; retailing of goods and services; o(fices; restauranls; and community, culturai and recreational uses. Considering the size of the Local Node parcel, as much as 1,000 square metres of non-residential space is anticipaled i( lhe property redevclops. The mix of uses permitted by the Local Node designation further enhances oppohunities for the Finch/Altona fntersection lo be the focus of the Neighbourhood, by providing for the day-to-day shopping needs of area residenls. Accordingly, redevelopment of this comer is strongly encouraged to accommodate a range of uses, fn particular, retail, commercial and o(fice space on ihe first (ew floors, with residential units on upper (loors.

How can the Town of Pickering be plenning to develop the Rouge Park Neighbourhood insida the Rouge-DutTn's Wildlife corrido�7 Is there not any consideruqon of Gmits to development7 1 am upset and unheppy about this plan. � . • i The current Rougc Park Neighbourhood plan will bc exremely damaging to the Wildlife Corridor in its function ns habitat. We have some smell trcasures in our town but they will be lost if we • keep developing and destroying. The Hydro Corcidor, the York-Durl�am Sanitary Trunk and the CP Rail line are not a sufTicient East-West wildlife corridor link between tha Rouge River and Du(iin's Creek. These areas ere subject to periodic herbicide spraying, removal of woody vegetalion and will remein highly diswrbed and in a state uf poor growllL ; I would like all the Ontario Realry Corporation lands wiUiin and adjacent tto Uie Rouge Park 't � Neighbourhood to remain publicly owned and to be Uansferred Gom thc provincial government to the Town ofPickering for additlion to tlie Rouge-Dumn's Wildlife Corridor. �; , , � ,. Can they really be considering devcloping thc Bcarc Eslate proparty next to Amos Ponds7 �, � Condominium Towero7 70 Townhomes7 I have grcat ditlicully believing this. One of Ihe �' pleasures of living in Pickering for the last S+ycars has been fccling a lilde closer to nature and lhe area around Mios Pond has contributed grcaqy to thal fecling. I heve takcn visitors for '� ` drivcs and spotted white tail deer in lhe field end beauliful swuns, great blue hcrons, night herons, ' kingfishcrs and more on thc pond. Onc glorious Jay my husbvid nnd i actually cnmc upon a.� molher phensunt with a dozen or more chicka jusl north of Ihe pond. These arc true lrcasures and contributc so much lo thc quality of lifc in Pickcring. � • , � ,. I urge lhe Town of Pickerin�; to purchase the_Beare Gslate property and add it to lhe Rouge- ' Du1Tin 1Vildlifa Corridor. Our grandchildren and thcir chilJren will be q�ankful and will be mora . — impressed with a town that held on to naturnl treasures than one which destroyed them to feed thc `� seemingly unending appetite for devclopment.

I am the only north Finch property that doea not have residentiai development on the south aide of thn road; I have two legal acceasea to Finch� I am in mid-blocki if the deve]oper retaina the house, the property is entitled to a 25� deneity bonus...this is the time at uhich thesc iasues are decided. I am totally opposed to Neighbourhood Concept D and E. , �: 172 z Z• Tf1E MIDENING OF FINC11 The Tartiery Plan and tho Ncighbourhood Concept muet ehou the widening of Finch. Preaently Finch hae a 66' right-of-uay expanded to 3 lanoa at the intereection with Altona� the municipal water eupply - 200mm pipe 30 years old ie located at the aouth edga of the right-of-uay. Finch ia an arterial H and will have a xidth of 30 to 36 metres. If Finch ie expanded to 30 metrea it uill become 98 feet Wide... 32 feet Hider than at present, presumably 16 feet uider on north and eouth, but Ne cannot aseume that until We aee it on a map. If Finch is expanded to 36 metres it uill become L18 feet uide, 52 feet Wider than at present and presumably 26 feet widar each sidei until it ia an a map ue cannot aseume the Widening will be taken equally. 26 feet ia quite a chunk out of anyone's front garden. Some propertiea at the intersection have already loat frontage. This is the time to diecover uhat further expanaian is naeded. Now is the Cime to reaolve the isaue of the Widening of Finch at the Amas' Ponde location. Presumably Finch uill not be expanded north into the Ponde. Doea this mean that Nr. Coddard and his neighboura Hill be uaked to give up 52 feet to tha roadl Amos' Ponda are in thc Rougu Park and thc Rougc Park hua a policy of no expaneion of exiating trnnsportntion fncilitiea. Doea thie mean that Finch uill bc Widened to an Arterial B as far ae Amos' Ponds then reducod to a 66' right-of-way. Thie is tha time to resolve thase isauea. I am requeating that the widening of Finch muat 6e ahoWn on the Tertiary Plan and the Neighbourhood DEvelopment Concept. 3.__ TIIE STATUS OF FiNCII In both the Phaea 1 and Phase 2 Reporte thera saume to ba a deliberete uttempt to portray Finch as a high-apeed, high-voluma nrterinl. Finch however ia an Arterial B nnd I uould augguat thut the Tranaportation aection quotos 4.10 (b) (11) of thc Pickering Official Plan... "Type B Arterial Roada: are designed to carry modernte volumes of traffic at moderate speeda, within a municipality� have some accesa reatrir.tionai and ganerally have u right-ot-wny width run�ing from 30 to 36 metrae." 4� THE HAP REALTY LAND_ASSEMBLY HLOCK �i This ia another area that Hap Realty ie intereated in developing... He have all been invi[ed numerous times by Hap Realty to hand over our properties to them in raturn for their advice! It would appear that there ie some secret a�reement between the municipality and Map•Realty on thie issue and certainly this large land asaembly provea it. Mr. Boiron atarted advertieing for investors promiaing "unusual returns" in the Clobe 6 Maii in October 1998. On inveatigation Hr. Boiron etatea that the promiaed returns - 25I to 35X - are due to the extremely loW purchase price of these propertias= he diatinguiehed betWeen his oun project and thia one. The extremely low purchaee price is bad newa for Linton, Smith, ���� 173 3 Barber and Holmea. I have to aek "Ie Nr. Doiron hallucinating or ie there indeud an agreement to hand over our area to a commercial real eatate company that can barely finance it own development and ie advertieing in the Globe 6 Hail for inveetore to buy out the longtime residente real cheap?" Certainly the lotting concept for Block 4 would support Mr. Boiron's claim that he has an underetanding uith the municipality. I would euggeat again - ae I did aftar the Phaee 1 Report - that Block 4 be divided into 3 parcels� Smith, Lintan and ORC, Barber aeperate and Holmae eeparate. I would auggest the Finch propertiea not be connected to Rosebank Road North becauae af the major engineering projecte thut are planned for that roadi in other aorda the aervice road ahoutd finish on the east boundary of/4v Barber. 5. THE PROBLEMS OF ROSEBANK ROAD NORTFI. Rosetrank Road North is not just another aideline road. The Region hae an interest in Rosebank North and ha{g already built a reaervoir north of the railuay tracke. Roae6ank is certainly the route of the York Loug Term Nater Projact and the eite of the Nater Filtration Plant. Roaebank Nill be invoived in changea to the York-Durham SeNer. Only one property uill be compananted...the Rosebank Road 10-acre property. To connact all the Finch properties to Aosebank Road is to sprend all the uncertaintiea and procraetinatione of thesa major ventures onto the propertiea of Darber, Linton nnd Smith. The Roaebank Road�ahould not have Finch accees...it hna no Finch frontage. If tha ptannera uiah to limit accesa to Finch uhy give Finch access to 80 lote thut are not entitled to it= eepeciully ae to use the acceae the propertiea of the much amallec neighboura - Linoon, Smith and Barber - are devalund by the volume of traffic coming from the Rosubank property. The Roaebank property ahould be serviced from Rosebank Road - seuer, wator and tranaportation. I do not necs how the expenditure for n eignnliaed intersection at Finch and Rosebank can be supported unlees tha Roaebank property ie confined to usina Rosebank for both entrance and exit. 6. DENSITY DONUS Is this not an iseue that should be dcalt With at this atage7 _ Nhan does ona get a fsnal anauer on thie7 7� FINCH ACCESS In the Phase 1 Report Concepte A, B, nnd C shoued Ili�h School and Neighbour6nod Park on the northeaet Finch propertiea. On November 23 Concept D ahoWe�e uneignallaed acceas for all 160 lota - 320 cars - and that accesa devalued the lots available to Smith and Linton by the quantity of interior traffic. On November 30 at the Advisory Committee Meeting I epoke to the fact tha6 all the concepts deprived me of the ability to aell my property ae a cul-de-sac development although I preaently have txo legal accesaes to Finch. In Concept E the sole accese for all 160 lota - 320 cara - ie placed on my property. I am opposed to Concept E. 174 4 A Fineh accese for my property only ia important. A proporty near the Altona interaection ie given a Finch accees� I am not near any intereection. I note that the retirement residencee have one legal accasa io Pioch but on tha Tartiary Plan they have tuo acceeeee to Finch, although ir�volving the traffic from feWar lota. I do not eupport any of the Concepta for northeast Finch. I think we need to limit thQ damage of tha York project by aliminating any proposed connection to Rosebank Road North. I xould like a cul-de-sac type of development and I require a Finch accesa for my property alone. Hhatever "arrangements" Pickering �ay have made, I do not want my property within any land aesembly. I would like to point out that my property haA dane its "community aervice" eineo 1972...far more than any other property in thie Hhole neighbourhood.

Your inco�poration of many of our commenls irom the 1" Draft Phase 2 Report into th(s 2"d Draft Phese 2 Report is greally apprectated. Please consider lhe following comments. Page 3-1, Section 3 Natura� Environment and Developable Lfmits, Paragraph 2, 2nd Sentence - Please chanpe to: '.,.nat have negatfve impacts on the features and functions of a- e end adjacent natural areas'. Thia correclian would be consislent wilh Section 5, topics that Environmenlel Reports should deal wilh where development ia proposed. Page 3-15, Section 3.5 Petlicoat Creek Evaluation, Netural Environment and Developable Limits, 2nd Paregraph from botlom - Piease change lhe last sentence to: 'It us be requirdd as �arl of an Environmenlel Report to fu�ther document conditions in the • watershed under more typical spring and summer conditions'. From the observations of the Rouge River Restoration Cammittee, Project Coordinator and meny volunteers, water levels (n the Pelticoat Creek Watershed in the Spring of 1999 were far higher than those observed in the Summer or Fall of 1999. In general the 1999 seasan was a dry one and did not represent lypfcal conditions in either the Spring, Summer or Fal!. pages 3-16 and 3-17, Sections 3,5.2 Petticoat Creek Fieid Survey Observations and Findings and 3.5.3 Flow Conditions - To our knowledge, the mein tribulary of Pettfcoat Creek upslream from the Rouge Park Neighbourhood was (and currently is) dammed by a Beaver prior to the field observations and flow condition measurements taken. The existence of lhe Beaver dam at the time of these observations would render them inaccurate untess the Beaver dam were to remain for lhe entire existence of the Rouge Park Neighbourhood. The presence of the Beaver dam along with the elypical dry 1999 condittons and the genaral dry conditlons of Summer and Fall at lhe t(me ot deta colleclion would in our apinlon neceasitate further obaervatlons and date colledion in ihe Spr(ng of 2000. We can guarentee you lhet the flow conditions observod on September 9'", 1888 are fer from typical Spring ftow conditlons. 185 In addition, weter level observatfons made for lhe Townline Swamp Complex in Aupust and September ot 1999 ere very fer from representfng Sprinp conditions. From our observationa, lhe differenc� in the amount oi waler wilhin lhe Rouge Park Nefghbourhood area observed in lhe Spring oi 1999 compared to the Summer and Fall is actuaily quite astounding. It would seem logical when planning a neighbounc�od thel water level observat(ons be made durfng peek water level condfl(ons (i.e. during lhe Sprinp) or lhat h(gh water marks be used to assess such conditions when possible. Page 3-21, Seclion 3.6 Developable Envelopes, 3rd Paragraph from bottom reads: `To change lhe developable limits K�II require the appropriete aupporpng environmental work fn lhe fonn of Environmental Reports (refer'to Section'5.0)'. To our understandfng, one of the mafn' �' objectfves of lhia nelehbourhood atudy Is to establish development envelopes or spatial limits to development wilhin the Rouge Park Neighbourhood. Th(s slatement should be removed as it inval(dates one of the major obJectives which lhfs study is intended to fulfil. Section 3 Nalural Envfronment and Developable Limits, Figure 3.4 Developable Limits displays a long double aided arrow North of the C.P. Rail L(ne merking an East-West Open Space -- Corridor through the Provincial agricultural lands. As lhis Open Spece Corridor (s (n fact Norih of the Rouge Park Neighbourhood lands, does lhis arrow fndicate the Town's intent to protect those agriculturel Iends direclly North of the nefghbourhood as en Eest-West Open Spece CoMdor to funclion as part of the Rouge-Duffin's Wildlife Corridor7 if this assumplfon (s correct, we would like to commend the Town on taking lhis (nitiative and would like to offer our highest level of suppott. Pape 5-1; S'ection 5 Environmental Report, 1" Paragraph, 2nd Senlence reads: `For os propeAfes in lhe Roupe Park Neiphbourhood, Rhe Pickering ONicial Plan will require that an Environmentai Report be submitted with eny development applicatians'. The use of the word most fn thls sentence implies that their exists c�iterfa which would permft the exemplion of certain properties wilhin lhe Rouge Park Nefghbourhood from submitting an Env(ronmental Repott along with an applicetion for developmenl We believe this should be changed to requfre all properties wilhin the Roupe Park Nelphbourhaod to submit an Environmentel Report — along with an applicetfon for development.

One possible solulion to Ih(s problem fs rather than lumping lhe developable privately owned lenda in wilh the developable Provincially owned lands, pool all of the developeble privetely ovmed lands lopether.

The total area (not necessarily the adual parcels) of Provincial�y owned lands within the Nefghbaufiood would be maintained as natural area, cutting lhe actual davelopment area by about 4096, allowinp for a ne(phbourhood concept lhat could be much more sympathetic to the natural features end funclians oi lhe neighbourhood and al lhe same time meet the challenge of maintaining e cohesive, well-designed neighbourhood. If the previously filled wetland areas in the neiphbourhood were restored, lhe actual area of development could be reduced by as much as 5096. This would ot course reduce lhe amount of developable land for those landovmers who filled wetlend on the(r properties.

Edge menagement b to provlde a bufler to protecl the neturel areas from edJecent land uses, end to protect land uses irom any hazerds thet mey be posed by naturel edges. 3.1 Stafl request en oppoAuniry to review the Breeding Bird Survey which was conducled by Ontario Hydro. In lhis regard staN are not certein ol lhe scope and scale ot tield Investfgatfons which were aclually undertaken aa the repott relers to reconnaissance level, hawever menUons breedfng birds nnd wildlife habitat which generally requires (feld invontory beyond reconneissance. 3.2 (Page 3-0) StaH concur with the flndings that'tor many species, the amount oi habilat with(n lhe lendscape Is more important than lhe size ol lhe individual patches.' Thfs has been evidenced in work condudad by Gartner Lee on the 8oare property where sensitive bird specles were found on the lorested ereas on lhe northem end eastem part of tha property. On its own in the landscape this habitat would rwt be expected to support such species. It is very Iikely that the habMat value for sensitive specles is being paAly supported by the proximity to lhe other torest hebitats within th(s part of lhe Rouge Corridor. 3.3 The Corridor FuncUans section of the report is not acceptable to TRCA slaH. In examin(ng lhe deiinilion of the cortidor, stafl note thet ihe cortidor should be noted es the'Rouge-Duilin Corridor' and not'Wildlife Corridor'. We note that the Rouge-DuHin Corridor was flrst klentifled by MNR biologbts whiie doing en aerial photograph examinalion ol this part ot lhe GTA They noNced that ihere were a number ot significent forest and wetland hebitels fn an east•west Ifne behveen the Rouge Fiver and the DuHin Creek. These included lhe ESA's at the north oi the Rouge, the Townlfne Swamp, Pineprove, Altona Forest and the Whftevale Cortidor ESA and the Duflin Creek. In addition lo these core habftats, a number of other forest hatidets were scariered along the same line. This line roughiy lollowed the Wlity cortidors that run east-west across lhis part of Pfckering. It was also noted that these habNa4s also follow the encient lake Iroquois ahoreline. � ...12 WORKING TOGETHER FOR TOMORROW�S GREENSPACE Ma Catherine L Roae • 2• February 4, 2000 197 Within e predominalely egdculturei matdx these habket patchea ere not totally isolated end many specias can move belween lhem. In fact, es noted earlier, the habNat patches act in concert to aupporl apecies that would not normally use such e small patch. It is recognked thet as agriculturei lends become developed, a number ot Impacts would occur which aHect the funcUon of these signHlcant habitets. Their eb(liry to funcUon collecUvely would be impaired. EssenQally urbanhed lands do not provide ihe same oppoAunkies lor movement as do egriculturai lands. /!+ core habttats become rtwre isolated the opportunfties (or sensitive species ere dimfnished. It . ror this reason ihal the core habitats, other forest hebitets, end the connected meadows easociated wilh ihe uUlity corridors were IdentNied as being en important part ot the natural heritege system es the lendscape changes. Steff quesNon the eppropriateness of the discusslon on the merits and demerits of the corridor withfn lhs document We note lhal lhere ere veryfng ergumenls on the validity o( corridors and lhe report eppears to focus on erguments which dlminish the need for corridors wilhin the landscape. For exemple, some species like woodland irogs found in the Town-Ifne swamp need to move between the weUends where they ere breeding to lhe lorests where lhey forege end ovetwinter. The points included on page 3•8 ere cortect, bul steH note lhat when there are core habftats that provide breeding habHet tor a species, there is a need to have some way for the young to disperse to other habkats (generally they cannot occupy the same territories as their paronts). As correclly noted, many species do not move in slraighl Iines along narrow pathways. Rather lhey move in a rather diHuse manner across lhe landscepe. 'Species that are ralher Inditlerenl to cortidors include red lox, coyote, and whKatailed deer. The coyote and fox tend to avoid corridors when Uavellfng across the landscape preferring to stey out in ihe open.. ' What is not recognaed is lhat once the landscape becomes urbanized, the ability ot many species (including the one's they described above) to move will be cuAailed. Providing for a serfes of core and other hebNats that are connected by the open fields associated with the utility corrfdor is en attempt to contlnue to provide lar lhe suite of species that currenlly exist in this part ol the reglon as the Iendscape maUix changes irom rural to urban. The report noles that gene flow along corrtdors has never been demonslrated but lhat it (s diHicult to study end cannot be dismissed. SteH suggest that lhis kind ol speculeUon is completely Inappropriate in this report. Secondly, while lhere may not be much (nformalion on genes moving in corridors, lhere hes been a huge amounl of study around whet is generally known es'island biogeography' that has shown how isolated habitals become genetfcally isoleted like islands (eg; tho Cia�apagos). As well, lhere have been sludles on some small mammals that has shown that once a barrier was created between the habitat patches, that the populetbns become generally isolated wilhin a couple of genereHons. In t.ddftlon stafl have lhe impressbn that corridors ere defined es forested areas only. This is not necessariiy true. Finally on ihis issue, the contradfctlon is noted on pages 3•10 which stetes that'noAh-soulh corridors ere funcNonfng are well.' Given the summary on corridors provided earlier fn the report, thb statement appears to ba (n conVadfdion. 3.4.1 The 8gure provided (3.2) is not clear in Identifydng the bounderies. The orange line representing the Rouge-Dutfin CorrWor appeara lo have large gaps. The line excludes tho lorested eastem part ot the Beare property that fs curtenlly under discussion. Secondly it was understood that the forested ereas on the east slde ot Woadview Ave. were to be part o(1he corridor. StaM do not support lhe low habitat value assigned to the north porUon ot the Beare Road property. Clariflcatlon Is requfred on the Ifmib of the cortidor on flgure 3.2 ../3 198 Ma.

We note lhat the quality, quantiry and movement of ground water ere ell crk(cal. The connections behveen lhe su�lace and subsurtace systems �eed to be Identliled and their lunclions mainlained. Given this we suggest that a water budgel needs to be conducted on a seasonal basis. • The report should note thal there should be no neaative imoacis on the veaetetion communities whlch in turn would equate to e benefit in wIIdINe habital oppoAunilies. • The proposed environmental report should look at opportunities to improve condiUons over what oxbts today. • Points Identified forlvea t are likely applicable over the entire erea. Staff are unsure why these points ere excluded lor area 3, 4 and 8. • StaH auggest thel there needs to be a mechanism to manage ihe cumulative impacts that result from all areas proposed lor development. Thfs report does not give any direction tor the required Envfronmentel Report to be conducted other than to suggest that the Emironmentai Report should demonstrate no negetive impacts. At minimum, there ehould be an IdenU(iceUon on some of the works to be undertaken by proponenis such es requirements lor fieid irnentories of amphibians, breeding birds, vegetaUon, dralnage pattems (surface end aubsurface), etc. Section 8 8.1 Edge Management Overview, artw�g the potenUal Impacts durfng construclion should inc�ude changes in drefnege. It shouid be rwted ihat post construcUon many of the Impacts lisled mey still occur such as drafnege changes, sofl compaclton, noise, erosion etc. end need to be managed/miUgated. .../4 199 Ma. Cetherine L Rose • 4- February 4 2000 The Impacte noted for new edgea ahould Include tncreased penetraUon of wind end Iight which can dry the undetatorey end resuft in chenpes In Ne swcture and apecles composition. The Impacts ol humen presence ahould include ihe lact ihet peopie end lheir pets are cont(nually in en area and will aBect the adJacent habitat by making it uninviting or unsuitable for some sensiWe species. Some ot the olher impacta that should be noted Include bright Iights and noise (eg. lawn mowers). The last paragraph on page 8�1 suggests thet'The type of edge man�gement roquired depends upon the natural features and functions lhat occur Q,p or edjacent to the property. .' Natural features should nol be }y[�i� the lots. Our experience has been lhat these features will not be protected In Ihe Iong term. 8•2.1. This secGon suggests that landscapfng adjncent to roads should be considered wildlite habitat. This cen atUact wildlKe into conflfcts wflh tre(�c and may ectually cause InJury or death to wildlile. ConslderaUon ehould be give� in the alfgnment end design ot roads to allow for the avoidance al conilict between wfldlife and Vatlic and promotes the safe movement of species between the verfous habitala. 8.2.2. This section Indicates thal In some instences no edge treatment olher than a setback may be required adjecent to disturbed habitats. YVhile applicable in ceNein areas s1aM are concerned that lhis standard wfli be applled in atl ereaa. We suggest lhat disturbed ereas may be most in need of enhancements to ensure their continued funclfon in the long term. 8.2.3. This section refers only to areas edJacent to watercourses. Reference should also be given to top ot banks and in floodlines. In ihis regard staM are uncertein of the recommendations ior buifers end meander belts. Figure 8.2. does nat seem to be rellective ol a buHer es described in the texL ClarHicaGon Is required on determination of the limfts ot open space. 8.2.4. Section 8.2.4 deals with ereas adJacent to woodlends. The report suggesis that drlpline plus 1 metre wfll be a no touch zone. There are e number of olher Issues that nned to be considered ensuring the rootzones of the edga trees are not Impacted. For instance, there may be e greater buffer required H there are specles that are very sensitive to humen presence, or it there is a need for grade changes. It cannot be assumed that ell iorests can heve trails running through lhem so there may bo a need lo have the trails routed oulside ihe edge. It should also be noted that some ol the lorests are swemps and are part ol the PSW so there are addfUonal consideraqons that have to be deatt with es per seclion 8.2.5. 8.2.5. The aecond poirn on groundwater should deal with the dming and location of releases. The need lor Vafls should be considered when deveioping bWfer requirements since lhey wfll not be allowed within the PSW lor the most part.

Stormwater manegement objectives should not preclude the protection of lhese areas, Figure 7.2 shows lhe conceptual locatfons for facllfUes. It appears that they are parlially wilhin forest and wetland habNats. Th(s is not acceptable. TRCA staH promote the protectlon of these habitats and strongly suggest thet the locations of all ponds be reviewed and epproved fn the field. 7.4.1 Section 71s the Section on Storm Water Management Strategfes. In ihe first sectfon the report oWines the objecUves for storm water menagement. The report should should include the protectfon and maintenance of the wetlands es well as the watercourse hab(tets. Flgure 7.2 shows ihe conceptual IocaUons lor faciliUes, it looks like they may be, at least parUy, within torest or wetland habitals. Again, ihis is not eppropriate. Sectfon 7.4.1 (ndicates the weter budget analys(s should estimate ihe change In the water budpet components. A water budget analysis needs to show how the changes will be managed or mftigated. In addition the budgets need to be seasonal end not annual as prescribed In this seclion. 7.4.3. The recommended approach does not mention lhe need lo pralect agninst Ihe (nlerceppon or truncalton oi shallow subsurtace Oows. Rather a b�anket approach is recommended whfch is to take backyard drainage to wetlands. As noled prevfousiy, Ihe amount, timing end locatfon of water being directed to wettands haa to Include the exisling condltions end needs to be conifrmed in a seesonal watur budget. It appeers that storm water may be taken turther downstream before it Is outletted. This may have impacls on base flow in the upper part of the Petticoat Creek. Impacts on Pelticoat Creek need to be examined. 8.4 The 5th bullet polnt suggesls that Stormwater Management facilitfes will be integrated into lhe natural setting. As noted prevbusly, all ponds must be located beyond the netural araes. SteN note that additionel comments will be lorwarded chortly as a result of our engineering section review of Sect(ona 7 and 8 0l llie report, in the interim we request ihat the ebove concerns be examined end that changes be made to the report to satisiy TRCA interests.
