The Philadelphia Water Department offers incentives to property owners, project managers, and developers to keep and increase stormwater management on their property for lower costs.
What are Development Incentives?
Incentives are available to development projects that include stormwater management beyond what is required by PWD’s Stormwater Regulations.
PWD Funding
Stormwater Grant funding
Development projects can manage additional on-site impervious area beyond the area required by the Stormwater Regulations. These projects can apply for Stormwater Grant funding.
Purchase of Assets
PWD Green Stormwater Infrastructure (GSI) projects are being planned all over the City, including in locations adjacent to proposed development projects. In these scenarios, PWD may engage the project’s developer with the option to construct the GSI on behalf of PWD. At the close of construction, PWD will purchase the GSI asset from the developer and take on long-term ownership and maintenance. This arrangement can be advantageous to both developers and PWD since it allows for the cost sharing of required street improvements including sidewalk repaving, accessibility ramps, and street trees and can reduce the overall length of time a street will be under construction.
Any applicant interested in incentive or grant opportunities for their project is urged to contact Stormwater Plan Review and Stormwater Billing and Incentives as early as possible in the design process.
Non-PWD Funding
Philadelphia C-PACE Program
The Philadelphia C-PACE Program is a financing tool that allows commercial property owners to borrow money for energy efficiency, water conservation, renewable energy, indoor air quality, and resiliency projects at long-term, competitive rates. Stormwater projects that go above and beyond Stormwater Regulations can be eligible for this program. If you are interested determining program eligibility for voluntary stormwater management, reach out to PWD_DevServices@phila.gov and cpace@philaenergy.org to discuss.
Zoning Bonuses
Green Roof Density Bonus: Contained in Section 14-702(16) of the Zoning Code, projects with certain mixed use and multi-family zoning classifications can include additional dwelling units beyond typical zoning code maximums by building a green roof.
Height Bonus for Stormwater Management: Contained in Section 14-702(14) of the Zoning Code, certain mixed use projects in the Central Delaware Riverfront Overlay (Section 14-507) and East Callowhill Overlay (Section 14-519) can gain height bonuses by including stormwater management features such as the management of street drainage, the management of additional on-site drainage, or the use of surface stormwater management practices such bioinfiltration/bioretention basins. Applicants interested managing street drainage as part of their project must schedule a pre-application meeting with PWD to confirm the available drainage area. Some street frontages may already be managed by existing PWD capital projects or other private development projects.
Why Development Incentives?
PWD is responsible for maintaining the health of our local waterways. This includes the management of stormwater runoff, the primary source of pollution in our rivers and streams. These incentives are offered by the PWD as a way to increase the amount of stormwater managed City-wide to ensure 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 combined and separate sewer permit requirements. Visit these pages to learn more about the benefits of GSI and the City’s many ways to plan and build it.
Learn more about other Stormwater Incentives
- The Stormwater Credits Program is the most commonly-used incentive for non-residential property owners to lower their stormwater bill. Property owners may be eligible today!
- Rain Check is the main incentive for residential property owners who want rain barrels, planters, or other free or discounted stormwater management practices installed on their property.
- Stormwater Grants are for non-residential private property owners that voluntarily manage stormwater runoff on their property, which may increase stormwater credit eligibility.
