What this page counts as McNorton
We could not find an openly licensed official boundary for McNorton, so this page uses a census-based area. For this page, McNorton 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 McNorton (feature 1341273) and inside the Corpus Christi city limits (U.S. Census Bureau), 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 McNorton.

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 McNorton?
The typical National Flood Insurance Program policy on single-family homes in McNorton costs $374 a year: the median of 13 policies that started between September 1, 2025 and August 31, 2026. Half of them cost between $367 and $738. 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.

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 November 2, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Nueces County (county code 48355), dataset as of September 8, 2026, retrieved November 2, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 483550035001. 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.
