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

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. 83 shorter streets are not listed.

Flood zones in Mount Washington
Share of Mount Washington’s mapped area (about 4.858 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 (06037C1626F, 06037C1627F, 06037C1628F, 06037C1629F): September 26, 2008.

| X (unshaded, minimal) | 100% |
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 Mount Washington?
The typical National Flood Insurance Program policy on single-family homes in Mount Washington costs $1,258 a year: the median of 16 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $1,080 and $1,435. 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 Mount Washington
FEMA’s National Risk Index rates heat wave risk for the census tracts that cover Mount Washington as: “Relatively Low” for 80%; “Very Low” for 20% of the area. Their heat wave risk scores range from 12 to 26 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 18% of Mount Washington’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.
Fire hazard severity zones in Mount Washington
California’s 2025 Fire Hazard Severity Zone maps place about 100% of Mount Washington’s mapped area in a Very High fire hazard severity zone (CAL FIRE Office of the State Fire Marshal, Fire Hazard Severity Zones).
The zones describe the fire hazard of the land, from vegetation, terrain, fire weather and wind-blown embers, not the risk to a particular home. Homes in these zones face stricter building and defensible-space rules, sellers must disclose the zone to buyers, and home insurance can be harder to find. Ask about the roof, vents and the clearance around the building, and get insurance quotes early.

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.
