What this page counts as Sunset District

We could not find an openly licensed official boundary for Sunset District, so this page uses a census-based area. For this page, Sunset District 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 Sunset District (feature 1659926), 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 Sunset District.

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 Sunset District

The named streets in Sunset District, longest first, with how much of each street’s length inside Sunset District lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Sunset District; 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. 21 shorter streets are not listed.

Streets: U.S. Census Bureau TIGERweb, Transportation (primary, secondary and local roads). Flood zones: FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, retrieved October 25, 2026. Each street is clipped to the area boundary and measured in an equal-area projection. Street lengths are rounded.

Flood zones in Sunset District

Share of Sunset District’s mapped area (about 6.443 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 17 to 23 feet. Effective date of the FIRM panel(s) covering it (0602980094A, 0602980113A, 0602980207A, 0602980230A, 06081C0007F, 06081C0026F): August 2, 2017, March 23, 2021.

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.

Flood insurance claims over time

Claims filed under the National Flood Insurance Program (NFIP) from the 2010 Census block groups that cover Sunset District. This area is made of whole block groups, so every claim counted here comes from inside it. Only insured properties appear, so these counts understate total flooding.

Named flood events with the most claims

How much is flood insurance in Sunset District?

The typical National Flood Insurance Program policy on single-family homes in Sunset District costs $1,080 a year: the median of 13 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $966 and $1,334. 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 City and County of San Francisco (county code 06075), dataset as of September 8, 2026, retrieved October 25, 2026. Claims are counted for exactly the block groups that make up the area.

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. Tree canopy: the mean of the 2025 NLCD Tree Canopy Cover values (0–100%, 30 m cells in an equal-area projection) for cells whose center lies inside the polygon. Fire hazard severity zones: the 2025 zone polygons (Local and State Responsibility Areas) intersected with the neighborhood polygon in an equal-area projection; the share of area in each class.
