| | | | | | | | OBJECTIVE
To recommend that the City Council award a contract to Stantec Consulting Services, Inc. for professional engineering services for the water improvement design of the Orangewood Avenue & Dale Street Project No. CP 1286000. |
| | | | | | | | BACKGROUND
The 2020 Garden Grove Water Master Plan was developed to evaluate the City’s existing and future water system. Performance and operational criteria were developed to define Orange County Fire Authority's fire flow requirements for new development, peak supply capacity, minimum and maximum distribution system pressures, booster pump station and storage facility sizing, and water main sizing. A capital improvement project list was generated based on evaluations using this criteria. The Orangewood Avenue & Dale Street Project is part of the recommended water improvements necessary to address fire flow capacity deficiencies and eliminate small size water mains.
The water improvement design project includes replacing approximately 7,800 lineal feet of 6-inch diameter asbestos cement pipe with 8-inch diameter polyethylene vinyl pipe, replacing and potentially relocating approximately 13 fire hydrants and 200 new water services. The project will also include abandoning approximately 200 water services. It includes three known tie-in locations to the existing water system. The consultant is responsible for developing bid documents that include construction plans, specifications and an engineer’s estimate. The contract agreement includes optional tasks for construction project management and inspection services. |
