Flood zones in Chesterfield Square
Share of Chesterfield Square’s mapped area (about 1.649 km²) in each FEMA flood zone, from FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels. Effective date of the FIRM panel(s) covering it (06037C1777G, 06037C1781G): December 21, 2018.
| FEMA zone | Share of area |
|---|---|
| X (unshaded, minimal) | 84% |
| X (shaded, 0.2% annual chance) | 12% |
| AE | 4.0% |
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 Chesterfield Square?
The typical National Flood Insurance Program policy on single-family homes in Chesterfield Square costs $907 a year: the median of 45 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $802 and $1,088. 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.

Extreme heat in Chesterfield Square
FEMA’s National Risk Index rates heat wave risk for the census tracts that cover Chesterfield Square as: “Relatively Low” for 100% of the area. Their heat wave risk scores range from 18 to 25 out of 100 (national percentiles). The index weighs how often heat waves happen, what they are expected to cost, and how vulnerable and resilient the community is, so a dense area can rate differently from a nearby one (FEMA National Risk Index, Census Tracts feature layer, Version 1.20.0 (December 2025)).
Trees shade streets and buildings and cool the air around them (U.S. EPA: Using Trees and Vegetation to Reduce Heat Islands). In the USDA Forest Service’s 2025 satellite-based tree canopy map, trees cover about 1.0% of Chesterfield Square’s area on average, compared with 8.6% for Los Angeles as a whole (the 114 Los Angeles areas on this site combined) (USDA Forest Service. 2026. USFS NLCD Percent Tree Canopy CONUS v2025-6 (2025 map). Salt Lake City, UT).
During a heat advisory, follow the National Weather Service: Heat Safety guidance. Neighborhood averages cannot tell you how hot a particular home, block or unit gets.

A 2010 Census block group is counted for a neighborhood when at least 25% of the block group lies inside the neighborhood, or at least 25% of the neighborhood lies inside the block group.

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.
