How Tuscola County floods

General flooding dominates Tuscola County's historical flood profile, accounting for 17 of the 23 total recorded flood events over the last 30 years, alongside three lakeshore flood events and three flash flood events. Strong winds and heavy rain have driven notable recent impacts, such as a January 2020 winter storm that caused significant lakeshore flooding and erosion along the shoreline, and thunderstorms in May 2019 that dropped over four inches of rain in southwest Tuscola County, resulting in road washouts and over $4.5 million in damage.

National Flood Insurance Program claims data indicates that risk varies significantly by zone. Homeowners and real estate agents in Zone A should pay the closest attention, as this zone accounts for the majority of historical claims (84 claims with an average payout of $10,887 and an average recorded water depth of 5 inches). Properties in Zone X_UNSHADED also warrant careful review by buyers and owners, as four claims averaged $29,462 with an average recorded water depth of 26 inches, while Zone UNKNOWN, Zone X_SHADED, and Zone X represent lower average payout and water depth frequencies.

Where the flood claims came from

From the storm reports

Lakeshore Flood · Jan 11, 2020. A winter storm tracking through southeast Michigan brought heavy rain and freezing rain, with about a quarter of an inch ice from US-10 south to about M-57. Many accidents and spin outs occurred across the Tri-Cities region and Flint vicinity due to the icy roads. In addition, strong northeast winds lead to high water levels and large waves causing significant lakeshore flooding and erosion along Bay, Tuscola, and…

Lakeshore Flood · Oct 31, 2019. High water levels over Lake Huron and northeast to north winds of 30-40 MPH produced large waves resulting in lakeshore flooding across Bay, Tuscola, and Huron Counties. The water level at Essexville peaked at 71.3 inches above chart datum. Shoreline erosion was reported at Port Hope.

Flood · May 25, 2019. Thunderstorms produced heavy rain, with 1 to 4 inches reported, generally along and north of I-69. Locations across southeast Saginaw and southwest Tuscola counties saw the heaviest rain, just over 4 inches which caused significant flooding, resulting in at least 4.5 million dollars of damage. Numerous roads around Frankenmuth were flooded, but most of the road washouts and damage occurred across the county line i…

Lakeshore Flood · Oct 16, 2019. Strong and prolonged northwest winds around 35 mph generated large waves over Saginaw Bay and southern Lake Huron. These higher waves and elevated water levels caused significant lakeshore flooding. Flooding to homes and roads were reported in Harbor Beach, Caseville, and Sebewaing. Erosion of the shoreline occurred at Port Crescent State Park. Finally, significant erosion and damage to seawalls reported in Lakep…

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.

Flood insurance in Tuscola County

If a building in Tuscola 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.
