Berrien County Flood Insurance & the 2024 Preliminary FEMA Maps

What FEMA studied in the Berrien County map update

The August 30, 2024 Preliminary FIRMs reflect detailed flood studies on multiple flood sources across Berrien County. The updated study spans 34 FIRM panels and covers 29 communities, including seven charter townships, eleven townships, six cities, and five villages.

Flood sources reassessed in 2024

• St. Joseph River — the largest single flood source in the county, draining a significant watershed before reaching Lake Michigan at the City of St. Joseph
• Paw Paw River — major tributary joining the St. Joseph River near Watervliet
• McCoy Creek and Hickory Creek — smaller streams with detailed studies
• Yellow Creek and West Tributary St. Joseph River
• Multiple named drains — Granger Drain, Goodrow Drain, both branches of Glenlord Road Drain, and Parker/Richardson Drain
• Lake Michigan shoreline conditions, particularly for the Cities of St. Joseph and New Buffalo

Where Berrien County stands in the FEMA process today

FEMA's flood map update process moves through specific regulatory stages. As of mid-2026, Berrien County is between the appeal stage and final effective date:

Until the final maps become officially effective, the currently effective FIRMs remain in force. For the City of St. Joseph, that means the maps effective April 25, 2024 (following the earlier appeal process). For other Berrien County communities, the current effective FIRMs are what apply — check msc.fema.gov for your specific address.

Communities covered by the Berrien County update

The 2024 Preliminary FIRMs cover 29 communities across Berrien County:

• Cities: Benton Harbor, Bridgman, Buchanan, Coloma, New Buffalo, Niles, St. Joseph, Watervliet
• Villages: Berrien Springs, Eau Claire, Galien, Michiana, Three Oaks
• Charter Townships: Benton, Lincoln, Niles, Oronoko, Royalton, St. Joseph, Sodus
• Townships: Bainbridge, Baroda, Berrien, Buchanan, Chikaming, Coloma, Galien, Hagar, Lake, New Buffalo, Pipestone, Three Oaks, Watervliet, Weesaw

If your property is in any of these communities, the new maps may change your flood zone designation. Use our Flood Zone Lookup tool to check both the currently effective designation and to watch for the updated maps once they become effective.

What flood insurance costs in Berrien County

FEMA's Risk Rating 2.0 methodology prices each property based on its specific characteristics rather than zone alone. General planning ranges for residential property in Berrien County:

• Zone X (preferred / low-to-moderate risk): typically $400 to $900 per year for an NFIP Preferred Risk Policy.
• Zone AE: typically $1,000 to $3,500 per year for NFIP coverage on a residential property. Most mapped St. Joseph River corridor properties fall here.
• Zone V or VE: typically $2,500 to $7,000+ per year for NFIP coverage. Limited to specific Lake Michigan shoreline parcels.

Private flood insurance has expanded significantly in Michigan since 2022. For higher-value Lake Michigan shoreline homes in St. Joseph, New Buffalo, and Bridgman — and for inland properties in moderate-to-high zones — private flood is frequently 20–40% less expensive than NFIP while providing higher coverage limits. NFIP's residential building coverage caps at $250,000; private markets routinely write $500,000–$1,000,000+. For older homes or properties with prior claims, NFIP may be the only viable option.

What you should do this month

1. Check your current effective flood zone. Use our Flood Zone Lookup tool or FEMA's Map Service Center to confirm what zone designates your Berrien County property today. This is the zone that determines your current insurance requirement.
2. Compare it to the 2024 Preliminary map. FEMA's Flood Map Changes Viewer (msc.fema.gov/fmcv) lets you compare the current effective FIRM against the Preliminary FIRM to see if your zone is expected to change when the new maps become effective.
3. If you expect a change to AE or V, start your insurance comparison now. Pre-shopping coverage before the new maps become effective gives you the most flexibility and can sometimes secure grandfathered NFIP rates that protect you from the new map's premium impact.
4. Consider an Elevation Certificate proactively. If you believe your property's lowest adjacent grade is above the projected Base Flood Elevation, getting an Elevation Certificate now from a Michigan licensed surveyor (typical cost $400–$800) positions you for a Letter of Map Amendment (LOMA) once the new maps are effective.
5. Call us at (920) 785-5019. We have written Michigan flood policies for years and have specific experience with the St. Joseph River corridor and the Lake Michigan shoreline.

Berrien County zone designations

Zone V or VE — Coastal High Hazard

Applied to Lake Michigan shoreline areas where wave heights of 3 feet or more are expected during the base flood event. In Berrien County, V zones are limited to specific shoreline parcels in St. Joseph, Bridgman, Lake Township, and Chikaming Township.

Zone AE — High Risk with Established BFE

Areas with a 1% annual chance of flooding where Base Flood Elevations have been determined. The majority of mapped flood-prone Berrien County properties — along the St. Joseph River, Paw Paw River, McCoy Creek, and other studied tributaries — fall in Zone AE.

Zone A — High Risk Without Established BFE

Areas with a 1% annual chance of flooding but where Base Flood Elevations have not been determined through detailed study. Some smaller tributaries in Berrien County are mapped as Zone A.

Zone X (Shaded) — Moderate Risk

Areas of 0.2% annual chance flooding or 1% annual chance with depths less than one foot. Insurance is not required but Preferred Risk Policies are typically very affordable.

Zone X (Unshaded) — Minimal Risk

Areas outside the 0.2% annual chance floodplain. Insurance is not required.
