Country Homes Blvd Phase 2 - Wall St to Division St/US395

Construction for the Country Homes Boulevard Phase 2 - Wall to Division project was completed in late fall 2016. The project involved constructing a stormwater facility within existing islands of Country Homes Boulevard, incorporating both disposal and water quality treatment. Country Homes Boulevard is a high average daily traffic (ADT), road located just north of the Spokane city limits and extends from Wall Street to State Route 395 (Division Street), approximately one mile in length.

About the Facility

The facility is a network of catch basins and pipes that collect and convey stormwater to bioinfiltration swales in the existing center islands. The swales are designed to treat and detain stormwater generated by pollution generating impervious surfaces, or PGIS, of the Country Homes Boulevard corridor. Drywells were installed in the swales for stormwater overflow, replacing existing drywells that did not have a treatment element. Country Homes Boulevard is an urban principal arterial with an ADT of 17,335.

This project is located over the Spokane Valley-Rathdrum Prairie aquifer which is designated as a sole-source aquifer by EPA, and provides drinking water for 500,000 people. This project was designed in accordance with the Spokane Regional Stormwater Manual which is an Ecology-approved, equivalent manual to the Stormwater Management Manual for Eastern Washington.
