What are Stormwater Incentives?

Stormwater Incentives are financial and development incentives to incorporate more (or keep existing) beneficial stormwater management techniques on private property. Different Stormwater Incentives can provide:

  • Some relief on a monthly stormwater bill with Stormwater Credits (Want to learn more about your stormwater bill? Visit our Stormwater Billing page).
  • A Stormwater Grant to design and build stormwater management practices (SMPs) on private property. These projects are then eligible for Stormwater Credits.
  • A lump sum or zoning allowances/exceptions for managing “extra” area in a stormwater project, known as Development Incentives.

Why Stormwater Incentives?

Different incentives are available to different properties based on property characteristics and proposed work to the area. These incentives are offered by the Philadelphia Water Department to manage stormwater for healthy and safe communities. This stormwater management goal is part of the Green City, Clean Waters plan to build more Green Stormwater Infrastructure (GSI) across the City as well as meet the City’s Stormwater Regulations. Visit these pages to learn more about the benefits of GSI and the City’s many ways to plan and build it.
