How Midland County floods

River flooding dominates the flood character of Midland County, supported by 15 recorded flood events compared to 5 flash flood events over the last 30 years according to the NOAA Storm Events Database.

Significant historical impacts occurred during a stalled low pressure system and frontal boundary that brought record rainfall of 4 to 6 inches to the Tri-Cities region from May 17 through May 19, 2020. This May 2020 event caused rivers across the region to flood, resulting in significant flooding along the Saginaw River and historic flooding across the area.

Homeowners and real estate agents should pay the most attention to properties in Zone A, which accounts for the vast majority of historical flood insurance claims with 460 claims averaging $61,432 and an average recorded water depth of 4 inches. Properties in Zone X also warrant attention, having recorded 66 claims with an average payout of $48,024 and an average recorded water depth of 4 inches.

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.
  4. X Outside both lines. No federal requirement to insure, which is not the same as no risk.

Flood insurance in Midland County

If a building in Midland 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.
