The Pennsylvania Statewide Flood Study, made available by the Pennsylvania Emergency Management Agency (PEMA) estimates housing damage due to flooding across the state. The corresponding flood study generated models of five scenarios (10, 50, 100, 200 and 500-year floods) based on streams and rivers with a drainage basin area of 10 square miles or more. I created maps of the modeled housing damage based on the number of damaged homes per census tract. I studied Mayfair, Kingsessing, the Germantown area, Eastwick, Grays Ferry, and South Philadelphia as a whole. These maps demonstrate that neighborhoods in South Philadelphia are at high risk of riverine flooding.

Predicted housing damage in Eastwick is widespread.

Germantown area housing damage is limited to around the river.

No flood damage is predicted in Mayfair.

Substantial damage is predicted in Kingsessing.

Predicted housing damage is widespread in Grays Ferry.

Predicted Damage in South Philly as a whole is severe.
