[Map: Offsite sanitary sewer plan for 9 Erskine Lane. The map shows the proposed development site with four buildings: BLDG A (79 units), BLDG B (79 units), BLDG C (107 units), and BLDG D (107 units). A red line indicates the offsite sanitary sewer route starting from Erskine Lane (manhole 531), crossing the Galloping Goose Trail, then the Trans Canada Highway (manholes 528, 527), and following Vickery Road and Viewcrest Drive (manholes 67A, 67, 66, 65A, 65, 64) toward the Helmicken Park Pump Station (manhole 63).]
