About the Stormwater Review Process

The purpose of the Stormwater Plan Review is to manage runoff and encourage natural infiltration and ensure all proposed development complies with federal, state and local regulations.

 

What is the purpose of stormwater code?

  • Managing stormwater runoff from land alteration and disturbance activities in accordance with watershed management plans.
  • Assuring that development activities do not result in increased stormwater flows.
  • Utilizing and preserving the desirable existing drainage system by preserving flood capacity of streams.
  • Stream quality maintainence and improvement in accordance with watershed managment.
  • Encouraging natural infiltration of rainfall to preserve groundwater recharge.

 

When is a stormwater plan required?

Stormwater Plan Reviews are triggered by one or more of the following:

  • 10,000 sq. ft. of land disturbance (any grading, excavation or fill activities that occur on a site) or 5,000 sq. ft. increase in impervious surface.
  • Publicly Funded Development  — Any development funded in whole or in part by public monies of at least $1,000,000, and that are in the form of any grant, loan that is forgiven or discounted below the market rate over the life of the loan, bond financing, infrastructure improvements related to a project, below-market sale or lease of property, or other form of financial assistance with an aggregate value over the life of all planned phases of development
  • Publicly Funded Redevelopment — Any land-disturbing activity that results in the creation, addition, or replacement of 500 sq. ft. or more of impervious surface area at a Publicly Funded Development.

 

How long will the process take?

The length of the review process depends on the complexity of the project.

When do I have to do a Small Project Stormwater management worksheet?

According to City of Pittsburgh Code Chapter 915.03, this Small Project Stormwater worksheet shall be completed for all projects with land disturbance of 500-5,000 square feet. This worksheet provides the property owner an opportunity to identify the type of proposed construction, including new impervious surfaces, and one or a series of BMPs that will be used to offset the stormwater impacts of any new impervious surface proposed. Before any land disturbance, you must call 811 to locate all utility lines on your property.

 

How do I start the process?

Please e-mail Martina Battistone, Senior Environmental Planner, any electronic submissions at Martina.Battistone@pittsburghpa.gov.

  • Conceptual Stormwater Plan — Optional, occurs during Zoning application submission
  • Final Stormwater Plan & Completed Checklist — Concurrent with site plan review or Pre-Development Plan review and approval
  • Modifications/Re-submissions — Any changes to a submitted Final Stormwater Management Plan require a re-submission and approval.

 

How do I end the process?

After you have resolved any issues, the Environmental Planner will prepare a consistency letter for the applicant. They will also prepare the project file for the Zoning & Development Review Division.
