ASCE LID Permeable Pavement Retrofit

The American Society of Civil Engineers (ASCE) Foundation owns a six-story office building in Reston, Virginia surrounded by several acres of asphalt pavement for parking ~300 vehicles. The building serves as the headquarters for this civil engineering society that consists of over 100,000 members. When the asphalt pavement was in need of milling and replacement in 2018, the American Society of Civil Engineers asked its Foundation for an approach that would demonstrate the Society’s commitment to sustainable environmental design via low impact redevelopment, specifically through runoff and pollution reduction.


The ASCE Foundation reached out to Society members (including CMHA staff) and vendors to donate design time, money and materials for a demonstration retrofit project for the parking lot. This resulted in a design and donations that captured and infiltrated about half of the runoff from the asphalt parking lot. The ICPI Foundation donated the construction of permeable interlocking concrete pavement (PICP) visitor parking consisting of 17 spaces and 7 for disabled users at the entrance.
