The City of Olympia has completed a roadway reconstruction project using innovative techniques to mitigate the project's stormwater requirements within the existing right-of-way. The reconstructed RW Johnson Boulevard incorporates two pervious concrete bicycle lanes adjacent to two asphalt vehicle lanes. The bicycle lanes treat and infiltrate the stormwater runoff generated by the vehicle travel lanes. The roadway project also includes pervious concrete sidewalks along the length of the roadway. The planter strip between sidewalk and roadway is amended with compost to enhance its infiltration capability. The use of these techniques allows the project to meet its stormwater requirements within the roadway right-of-way. The pervious concrete used for this project is a new material with a surface texture very similar to regular concrete. The concrete has a high fines content (75%) resulting in a smooth finish for the bicycle lanes and sidewalks. This paper details our experience with the design, construction, and costs of pervious concrete bicycle lanes and sidewalks.
