What this page counts as Carrollton
We could not find an openly licensed official boundary for Carrollton, so this page uses a census-based area. For this page, Carrollton means the 2010 Census block groups whose center lies inside the National Register of Historic Places boundary of the Carrollton Historic District and Carrollton Historic District (Boundary Increase) (National Park Service). 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 Carrollton.

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 Carrollton
The named streets in Carrollton, longest first, with how much of each street’s length inside Carrollton lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V).

Flood zones in Carrollton
Share of Carrollton’s mapped area (about 4.736 km²) in each FEMA flood zone, from FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels. Mapped base flood elevations inside the neighborhood range from -2 to 0 feet. Effective date of the FIRM panel(s) covering it (22051C0185F, 22051C0195F, 22051C0225F, 22071C0209F, 22071C0217F, 22071C0228F): September 30, 2016, February 2, 2018.

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 Carrollton?
The typical National Flood Insurance Program policy on single-family homes in Carrollton costs $1,082 a year: the median of 1,796 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $982 and $1,239. 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.

Area: the census-based definition above, using U.S. Census Bureau TIGERweb, 2010 Census Block Groups, National Park Service, National Register of Historic Places boundaries (NRHP polygons) 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 24, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Orleans Parish (county code 22071), dataset as of September 8, 2026, retrieved October 24, 2026.

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.
