New Stormwater Regulations for July 2015

Philadelphia Water Department

Abstract: Effective July 1, 2015, the Philadelphia Water Department (PWD) will update its Stormwater Regulations for development in order to meet the requirements of the Clean Water Act. The changes will improve the health of Philadelphia’s rivers, minimize local flooding, and encourage the use of green infrastructure throughout the city.  In addition, PWD is updating its resources and processes to improve and clarify the PWD plan review process.

PWD first implemented the Stormwater Regulations in 2006. Since then, the Water Department has negotiated new permits with Pennsylvania’s Department of Environmental Protection. In 2011, PWD and the State agreed to Green City, Clean Waters, the 25-year plan for managing combined sewer overflows. In addition, PWD has submitted to the State several Act 167 Watershed Management plans for different watersheds in the City. The changes to the Stormwater Regulations are necessary to meet the goals outlined in Green City, Clean Waters and Philadelphia’s other regulatory obligations.

The Water Quality improvements will require each development site to manage more water, by increasing the Water Quality Volume from 1 inch to 1.5 inches.  In addition, the peak release rate will decrease from 0.24 to 0.05 cubic feet per second per acre of non-infiltration impervious area, giving treatment plants more time to clean the water before it reaches our rivers.  Finally, each site will be required to filter the dirtiest stormwater running off the site, 100% of the non-infiltrated runoff must be routed through a pollutant-reducing practice.

This will be the first significant change to the Regulations and Guidance Manual since 2008 and represents an opportunity to improve PWD’s Plan Review process based on several years of feedback from the Development Community.  In addition to the regulatory changes, PWD will introduce new business-friendly improvements including a new expedited review option, simplified technical worksheets and application materials, and a new Stormwater Management Guidance Manual and website.
