Philadelphia Stormwater Permit Checklist - City Ordinance
Philadelphia, Pennsylvania property owners, developers, and contractors must follow city stormwater permit requirements when projects alter drainage, increase impervious area, or affect the public right-of-way. This checklist explains common permit types, documentation, review steps, enforcement pathways, and practical actions to reduce review delays during design, construction, and post-construction maintenance. Use the steps below to prepare applications, avoid common violations, and know where to report noncompliance; consult the official Philadelphia Water Department stormwater permit pages for forms and technical guidance at the time of application: Philadelphia Water Department stormwater permits[1].
Overview
The City of Philadelphia regulates stormwater to protect public infrastructure and downstream water quality. Projects that add impervious surface, change drainage patterns, connect to public sewers, or work in rights-of-way commonly require review. Thresholds, standards, and required best management practices (BMPs) are described in the city technical guidance and permit pages referenced above.
What permits are commonly required
- Stormwater plan approval or permit for new or redeveloped sites that change runoff management.
- Right-of-way or street-opening permits when work affects curb, gutter, or storm inlets.
- Construction permits and erosion-and-sediment (E&S) controls tied to site disturbance.
- Post-construction operation and maintenance agreements for stormwater controls.
Applications & Forms
Official application forms, plan checklists, and technical manuals are published by the Philadelphia Water Department; specific form names and fee schedules are posted on the department site referenced above. If a specific fee or form number is required for your project, check the official permit page for the current PDF application and submission instructions; fee details are not specified on the cited page.
Eligibility & Thresholds
Thresholds depend on project type, area of impervious cover added or replaced, and whether stormwater management measures are proposed. Small maintenance projects may be exempt; substantial redevelopment typically requires full stormwater plan approval. Confirm exemption criteria with the Water Department and review the technical guidance for sizing BMPs and design credits.
