Recently the San Francisco Public Utilities Commission (SFPUC) and project stakeholders celebrated the completion of the Holloway Green Street at its ribbon cutting ceremony. The highlights of the ceremony were the demonstrations of the pervious concrete parking lanes and rain gardens.
The pervious concrete parking lanes were designed to infiltrate and treat stormwater from the roadway, while the rain gardens were designed to treat runoff from the sidewalks. The eight block long green infrastructure system will manage nearly 1 million gallons of stormwater annually. This is the first project in San Francisco to use pervious concrete in the public right-of-way. David Liguori, Bay Area Pervious Concrete's President, joined the celebration and was even invited to hold the ribbon for cutting.
The Holloway Green Street is also the first of eight stormwater infrastructure projects to be completed as part of the SFPUC Sewer System Improvement Program. All eight projects were strategically located atop the city’s eight urban watersheds. Once completed the projects are expected to infiltrate over 17 million gallons of stormwater per year, reducing pressure on the city's combined sewer system, and thus increase capacity of the current system. The program's ultimate goal is to use green infrastructure to infiltrate and treat a billion gallons of stormwater by 2050.
With such fan fare and excitement around this project we are sure to see more pervious concrete in the San Francisco's public right of way. If you stop by the project let us know what you think!
