Executive Summary: The City of Pickering retained the services of The Municipal
Infrastructure Group (TMIG) for the Krosno Creek Flood Reduction Study which was completed in
February 2015. The study determined that the preferred solution to mitigate flooding, and ongoing
erosion concerns along the creek, is to replace the existing culverts at Morden Lane, Alyssum
Street, and Reytan Boulevard with larger culverts.
Detailed design was completed by TMIG in the spring of 2019. Through the detailed design
process, it was determined that gas main relocations are required to create the necessary space
for construction of the proposed concrete box culverts.
Enbridge Gas Inc. has provided cost proposals for the three gas main relocation sites on Morden
Lane, Reytan Boulevard and Alyssum Street. The proposals provided are governed under the
Municipal Franchise Agreement for Cost Sharing with Enbridge Gas Inc. The City’s apportioned
cost is 35 per cent of the total project cost, while 65 per cent is the responsibility of Enbridge Gas
Inc. The cost proposals indicate that the City’s portion of the works is $296,872.94 (HST included).

Discussion: The City of Pickering retained the services of The Municipal
Infrastructure Group (TMIG) for the Krosno Creek Flood Reduction Study which was completed in
February 2015. The study determined that the preferred solution to mitigate flooding, and ongoing
erosion concerns along the creek, is to replace the existing culverts at Morden Lane, Reytan
Boulevard and Alyssum Street with larger culverts.
Detailed design was completed by TMIG in the spring of 2019. Through the detailed design
process, it was determined that gas main relocations are required to create the necessary space
for construction of the proposed concrete box culverts. The proposed gas main relocation
requirements include;
•Morden Lane – installation of a new gas main, 4” steel intermediate pressure (90m) pipe. The
existing 4” gas main (south side) is to be abandoned;
•Reytan Boulevard – installation of a new gas main, 2” plastic intermediate pressure (19m) pipe
and one existing service to be relayed. The two existing 2” gas mains (north and south sides)
are to be abandoned; and;
•Alyssum Street (including Sandy Beach Road) – installation of a new gas main, 4” steel high
pressure gas main along the east side of Sandy Beach Road, reconnecting two existing
commercial services. Part of the existing 4” gas main on Alyssum Street is to be abandoned.
Enbridge Gas Inc. has provided cost proposals for the three proposed gas main relocation sites.
The cost proposals provided are governed under the Municipal Franchise Agreement for Cost
Sharing with Enbridge Gas Inc. The City’s apportioned cost is 35 per cent of the total project cost,
while 65 per cent is the responsibility of Enbridge Gas Inc.. The total estimate for the City’s portion
is $296,872.94 (HST included).
Engineering Services staff have reviewed the cost proposals and plans submitted by Enbridge
Gas Inc. and recommend acceptance of the cost proposals from Enbridge Gas Inc. in the amount
of $296,872.94 (HST included), and recommend a total net project cost of $294,078.00 (net of
HST rebate) be approved.
