2016 Permeable Streets

2016 Permeable Street Retrofits


Following utility replacement work necessary on 14th & 15th Street PL NW, just south of 4th Ave NW, the City will retrofit and repair the roadway surface in these locations, installing pervious concrete and porous asphalt. This project will provide on-site stormwater management for these locations to address seasonal localized roadway flooding events, and support water quality improvements through the application of green stormwater infrastructure. The use of pervious concrete and porous asphalt in these two locations will provide an on-site example of the durability of the two pavement types using the City's most-recent specifications which include strengthening fibers for each. Long-term maintenance and performance of these pavements will provide information to the City on application for future projects.
