From the storm reports

Flash Flood · May 21, 2014. A nocturnal convective complex brought training thunderstorms to north-central Pennsylvania during the early morning hours. A localized 3-5 inches of rain fell over a 8-10 hour period which resulted in significant flash flooding in Elk and northern Clearfield Counties. Flash flooding, to a lesser extent, also occurred in adjacent Warren and Cameron Counties.

Flood · Jan 25, 2010. Heavy rainfall between 1 and 4 inches produced widespread areal flooding across all of central Pennsylvania. Cold season hydrologic conditions, including snow and ice melt contributed to enhanced run-off especially across the higher elevations and northern mountains. Many small streams and creeks came out of their banks, resulting in numerous secondary road closures.

Flood · Dec 1, 2010. Widespread heavy rainfall of 2 to 4 inches produced extensive flooding across Central Pennsylvania for the first three days of December 2010. The heavy rain fell in two distinct periods with the first round of 1-2 inches falling by the evening of November 30th. The second period of heavy rain fell overnight into the afternoon on December 1st. The initial rainfall on the 30th resulted in antecedent conditions that…

Flash Flood · Jul 12, 2004. Heavy rain caused flooding in Elk County, especially in the Johnsonburg and St. Mary's area. Numerous roads were flooded and closed, and many reports of flooded basements were received.

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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.

Flood insurance in Elk County

If a building in Elk 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.
