What this page counts as Mertz

We could not find an openly licensed official boundary for Mertz, so this page uses a census-based area. For this page, Mertz means the 2010 Census block groups whose center lies within 1.6 km (1.0 miles) of the U.S. Geological Survey (GNIS) map point for Mertz (feature 152305), each block group going to the nearest of the places we cover. Every number below is for exactly those block groups (listed in “How these numbers were made”), so the edges are approximate and may include or leave out a few blocks people would call Mertz.

Past claims do not predict future flooding, and a neighborhood figure cannot tell you about one building. Look up the exact address on the FEMA Flood Map Service Center and get flood insurance quotes before you sign a lease or a contract.

Flood zones street by street in Mertz

The named streets in Mertz, longest first, with how much of each street’s length inside Mertz lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Mertz; the main zone is the FEMA zone covering most of that length. A street can cross several zones, so the zone at one address can differ from the street’s main zone: check the address above for that. 63 shorter streets are not listed.

What the zones mean

Zone AE (and A, AH, AO)
High-risk: part of the Special Flood Hazard Area (SFHA), the area FEMA maps as having a 1-percent chance of flooding in any given year (the “100-year” or base flood). AE areas have a mapped base flood elevation.
Zone VE (and V)
High-risk coastal areas, also in the SFHA, where the base flood is expected to bring additional hazards from storm waves.
Zone X (shaded)
Moderate hazard: between the limits of the 1-percent and the 0.2-percent-annual-chance (“500-year”) flood.
Zone X (unshaded)
Minimal hazard: outside the SFHA and higher than the 0.2-percent-annual-chance flood elevation. Minimal is not zero: flood claims are filed from X zones too.

How much is flood insurance in Mertz?

The typical National Flood Insurance Program policy on single-family homes in Mertz costs $946 a year: the median of 16 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $735 and $1,159. That is the full amount paid for the year, the premium plus FEMA’s fees and surcharges, and every one of these policies is priced under Risk Rating 2.0. A quote for one building can be far from this: its elevation, foundation, age, coverage and deductible all change the price. Private flood insurance is not included.

How these numbers were made

Area: the census-based definition above, using U.S. Census Bureau TIGERweb, 2010 Census Block Groups and U.S. Geological Survey, Geographic Names Information System (GNIS) domestic names. Flood zone shares: the area polygon intersected with FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, area computed in an equal-area projection; retrieved October 25, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Mobile County (county code 01097), dataset as of September 8, 2026, retrieved October 25, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 010970014003, 010970023022, 010970023011, 010970014002, 010970015011, 010970024001, 010970024002. Neighboring pages can share a block group, so their counts can overlap. Paid totals add building, contents and Increased Cost of Compliance payments and are not adjusted for inflation; a claim whose FEMA record shows a negative payment (an adjustment) counts as zero.
