Proposed Motion
That Council approve $300,000 in Gas Tax Funding for the construction of the Pond 1-5 outlet connection.
Body
Administration Recommendation
Administration supports the proposed motion.
Purpose
Construction of the Pond 1-5 outlet connection will provide the necessary connection to the Acheson Stormwater Outfall line(main line) that is required to allow this isolated stormwater pond to drain.

The January 2013 Acheson / Big Lake Basin 1 (Zone 5) Storm Design Report recommended the Zone 5 Collector Line be constructed approximately 780 m north of what was originally anticipated. The recommended alignment improved the efficiency of the overall system and provided a cost savings of approximately $2,000,000. The developer for the lands is prepared to fulfill their original obligations of constructing a stormwater lift station and 60 m of outlet connection. They are also prepared to construct a...
