July 2018 Updates to the PWD Stormwater Regulations


Effective July 2, 2018 the Philadelphia Water Department updated its Stormwater Regulations including changes to how streets are regulated. The specific changes are as follows:

  • Street Maintenance activities no longer count towards the earth disturbance threshold for triggering the PWD Stormwater Regulations.
  • New Streets must meet the Water Quality Requirement. 

PWD has also updated the Philadelphia Stormwater Management Guidance Manual. The Manual Version 3.1 includes new guidance about managing Street runoff, revised porous pavement guidance, new One-Sheets, additional design examples, and other clarifying edits. Designers should begin using the updated Manual immediately for all project submissions.

In addition, PWD introduced an updated Project Portal, which allows multiple projects to be managed from one location. A new Online Technical Worksheet was also introduced that can be accessed from the portal. Designers are strongly encouraged to start using the Online Technical Worksheet for any new Post-Construction Stormwater Management Plan (PCSMP) submissions as it will be mandatory beginning October 1, 2018.
