How Monroe County floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Monroe County, Pennsylvania, accounting for 63 of the 85 total flood events recorded over the last 30 years, alongside 21 general floods and 1 tropical storm event resulting in a combined 3 deaths. Severe weather has repeatedly impacted the region, including an approaching cold front that sparked flash flooding on July 14, 2025, and thunderstorms that brought 3 to 6 inches of rainfall to the Pocono Region on July 14, 2023. Additionally, Post Tropical Cyclone Ida brought 5 to 10 inches of rain and significant flash flooding on September 1, 2021.

National Flood Insurance Program records indicate that property owners in high-risk Zone A face the heaviest impacts, logging 267 claims with an average payout of $53,718 and an average recorded water depth of 23 inches. However, property owners outside of primary high-risk zones must also remain vigilant; Zone X properties recorded 122 claims with an average payout of $30,645 and an average water depth of 15 inches, while smaller numbers of claims were filed in unshaded and shaded X zones and unknown zones. Homeowners and real estate agents in both designated special flood hazard areas and lower-risk zones should pay close attention to these historical water depths and claim histories.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Monroe County

If a building in Monroe County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
