Why build the CHBRP?
Spokane County’s NPDES Phase II permit, a permit required by the EPA and administered by the Washington State Department of Ecology, states that the County must provide water quality retrofit facilities in an effort to treat polluted stormwater before it reaches a surface water body or drinking water source.

The Country Homes Boulevard channel is the main conduit for transporting stormwater runoff within the Five Mile Watershed to the Price and Wall Regional Stormwater facility. While Price and Wall is a water quality treatment facility, it does not have the capacity to treat all of the potential stormwater pollutants that reach the facility via the channel.

Almost all of the pollution-generating impervious surfaces (i.e., roads, sidewalks, roofs, and driveways) that stormwater runoff flows across (starting from the Prairie on down to the channel) is currently lacking any stormwater pre-treatment.

By restoring the Country Homes Boulevard channel, we approach meeting the treatment requirements of today’s water quality standards.
