[Plan view map showing the offsite sanitary sewer route from 9 Erskine Lane. The route begins at the development site with Buildings A (79 units), B (79 units), C (107 units), and D (107 units) on Erskine Lane near Watkiss Way. The sewer line travels along Erskine Lane and the Galloping Goose Trail, crosses the Trans Canada Highway, continues through Vickery Road and Viewcrest Drive, and ultimately connects to the Helmcken Park Pump Station near Craigflower Creek.]
