Document Description
The purpose of this project is to improve wastewater and stormwater facilities at the Corporation Yard. The project is needed because floods in 2005-2006 ruined the former office building and damaged the existing stormwater pump house. Mobile offices that replaced the flooded office building are currently utilizing a temporary waste system. The proposed improvements would achieve the following objectives: 1. Convey sanitary wastewater from the office building to the City's WWTRP; 2. Direct stormwater from the Corporation Yard operations area storm drains to the City's WWTRP, minimizing stormwater runoff and improving water quality discharge to Sulphur Creek; 3. Repair the existing pump house to service stormwater runoff from the building roofs and gutters, as well as sheet flow on Charter Oak Ave.; 4. Improve wastewater services for other parcels along Charter Oak Ave., in accordance with the City's Highway 29 Specific Plan, by providing an available sewer line; and 5. Increase safety by replacement and relocation of the damaged emergency siren/alarm within the Corporation Yard.
