Hazard Mitigation Plan

Reducing Philadelphia’s Risk

What is the Hazard Mitigation Plan?

Hazard mitigation is the act of reducing or eliminating the risk of natural, human-caused, or technological disasters. The Hazard Mitigation Plan (HMP) describes which hazards, like flooding and winter storms, affect Philadelphia. The plan also looks at what City projects can help reduce damage from disasters before they happen.

Priorities for the 2022 plan include equity, climate change, and alignment with other City processes and plans. The plan looks at 18 different hazards and lists 163 actions the City can take to reduce our risk.

Overall, more than 190 people from 85 different agencies and organizations engaged in the 2022 update. Public comments from nearly 400 public surveys and numerous community events informed the plan.
