Overview of Rules and Jurisdiction

Allentown regulates land use through its municipal code and through department-level permit rules. Floodplain and stormwater management are enforced as part of public works and development review; wetlands permitting may also rely on state PADEP approvals for impacts to regulated wetlands. Consult the municipal code for zoning overlays and tree protections for public rights-of-way and street trees. For the municipal code and ordinance text see the city code publisher page[1]. For Allentown stormwater and floodplain contacts see the city public works page[2]. For state wetland permit requirements see PADEP guidance[3].

Permits and When They Apply

  • Work in mapped floodplains or floodways - permit or variance typically required.
  • Permits for tree removal on public property or in rights-of-way; separate rules may cover historic districts.
  • Wetland impacts - local review plus state wetland permit where PADEP jurisdiction applies.
  • Grading, land disturbance or stormwater control permits for development activity.
If in doubt, request a pre-application meeting with Planning or Public Works.

Penalties & Enforcement

Enforcement is carried out by city Code Enforcement, the Department of Public Works, and Planning/Zoning as applicable; state enforcement may apply for wetlands through PADEP. Specific monetary fines and daily penalties are not consistently specified on the cited municipal pages and thus are noted as not specified on the cited page where absent[1]. See the contact links in Help and Support for reporting and appeals.

  • Fines: not specified on the cited page for municipal code penalties; state wetland fines appear on PADEP pages when applicable[3].
  • Escalation: municipal practice may include increased fines for repeat or continuing offenses; exact ranges are not specified on the cited municipal pages.
  • Non-monetary sanctions: stop-work orders, restoration orders, permit revocation, and court actions may be used.
  • Enforcer and inspections: Code Enforcement and Public Works staff conduct inspections; complaints can be submitted via city department pages[2].
  • Appeals and review: appeals typically go to the zoning or hearing board; specific time limits for appeals are not specified on the cited municipal pages.
  • Defences/discretion: permitted work, variances, emergency actions and reasonable excuse are considered case-by-case under city discretion.

Applications & Forms

Applications, checklists and permit forms are maintained by the city departments. The municipal code publisher lists ordinance language but application forms are on department pages or PDF forms at the city site; if a specific form number or fee is not published on the department page this guide notes that it is not specified on the cited page. For stormwater and floodplain submittals see the Public Works permit page[2]. For state wetland permits and application forms see PADEP resources[3].

  • Tree removal on public property: submit a tree work permit application to the city (form and fee not specified on the cited page).

Common Violations

  • Unauthorized tree removal in the public right-of-way.
  • Unpermitted grading or fill in mapped floodplains.
  • Wetland disturbance without a PADEP permit when state jurisdiction applies.
Stopping work immediately and contacting the city can reduce escalated penalties.
