Oakwood-Batavia Green Stormwater Infrastructure
The Oakwood-Batavia site is the largest GSI project we have constructed and showcases the ability to use GSI to handle water in low-lying areas that cause flooding in the public right-of-way. The project includes a bioswale bumpout – the first bumpout constructed in the City of Pittsburgh – along with a green gutter on Oakwood and Batavia Streets.
As a result of this 2016 project, runoff not infiltrated is piped across Batavia Street to an underground storage system that holds water and slowly infiltrates it during heavy rains. The project is beautifying a blighted corner that is characterized by several vacant lots. This site was part of the Rosedale Runoff Reduction Project.
The site is designed to capture between 700,000 – 1.7 million gallons of stormwater runoff annually, with an annual cost per gallon removed of $0.36 – $0.16. For more detail, please view this report by Ethos Collaborative.
