Project Number: 2010087
Project Budget: $24,000,000.00
Description and Location:
CSO 24 is part of the continuing efforts of the City to enhance and protect one of our most precious resources, the Spokane River. This project protects the Spokane River from sewer overflows during rainstorms and spring runoff events by holding the excess water/sewer flow that would normally discharge directly into the river. The tank holds approximately 2.4 million gallons of stormwater.
The finished project will include a new plaza over the tank, repaved streets, a dog park and new pedestrian facilities. The project is located near the intersection of 1st Avenue and Adams Street.
The city is delivering this project using an alternative contracting method called GC/CM as opposed to traditional design/bid/build. This method was chosen to best address the complexities of building a very large tank in some of the oldest parts of town and to take advantage of a prime contractor’s building experience as a team member during the design process.
Current Traffic Control Plan: All businesses are accessible by sidewalk and parking is accessible where shown on the map below. Underground pipe work in 1st Avenue will take place May to July 2018. As work progresses the traffic control map will be updated.
