Description

The Sharp Avenue Permeable Pavements project is part of the City of Spokane’s larger effort to remove PCBs from the Spokane River. The project limits are within a larger basin area in north Spokane that topographically drains south toward the Spokane River through three separate MS4 pipes. The project constructed multiple cross sections with both pervious concrete and porous asphalt to provide stormwater separation from the MS4 system. These cross sections include full width (curb to curb) permeable pavements, bike and parking lanes only and full intersections. These multiple cross sections allow the city to evaluate which cross sections constructed of which materials are viable in the traveled way. The City has constructed four sample stations with this project to monitor the treatment effectiveness of the different permeable materials and cross sections that were installed. In addition to the water quality component, the City is also monitoring the durability of the pavements as well as maintenance practices.
