What this page counts as Elmhurst
We could not find an openly licensed official boundary for Elmhurst, so this page uses a census-based area. For this page, Elmhurst 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 Elmhurst (feature 1692996) and inside the Oakland 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 Elmhurst. Sources: U.S. Census Bureau TIGERweb, 2010 Census Block Groups and U.S. Geological Survey, Geographic Names Information System (GNIS) domestic names.
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.

Neighborhood figures are averages. Our address check looks up the FEMA flood zone and California’s fire hazard severity zone at one address, from the same public maps: check if your address is in a flood zone.
Flood zones street by street in Elmhurst
The named streets in Elmhurst, longest first, with how much of each street’s length inside Elmhurst lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Elmhurst; 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. 59 shorter streets are not listed.

Flood zones in Elmhurst
Share of Elmhurst’s mapped area (about 5.399 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 (06001C0089J, 06001C0095G, 06001C0252H, 06001C0256G, 06001C0257G): August 3, 2009, December 21, 2018, May 26, 2026.

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.

Half of them cost between $1,250 and $2,102. These policies are priced under Risk Rating 2.0.
- ZIP code 94621: NFIP records list 43 flood claims with a loss year from 1980 through 2021. The claims dataset is as of September 8, 2026.

Fire and wind
- Official state fire hazard maps: Very High 0%, High 0%, Moderate 0%, outside any mapped zone 100% of Elmhurst. The publisher of these maps does not endorse this site.
- USDA Forest Service Wildfire Risk to Communities gives Oakland, CA a Risk to Homes national percentile rank of 0.824, which its methods call High (above the 70th percentile and below the 90th). That is the city rating, not a rating of Elmhurst alone. The summary file is dated April 15, 2026.
What to ask your agent
- Ask the agent how old the roof is.
- Ask whether a wind-mitigation discount is available for this house.
- Ask how flood coverage differs from the homeowners policy. A standard homeowners policy does not cover flood. Flood coverage is a separate policy.
- Ask whether the policy has a separate hurricane or windstorm deductible, and how that deductible is calculated.
- Ask when coverage would start. A new National Flood Insurance Program policy generally takes effect 30 days after purchase.

Extreme heat in Elmhurst
FEMA’s National Risk Index rates heat wave risk for the census tracts that cover Elmhurst as: “Relatively Low” for 81%; “Relatively Moderate” for 19% of the area. Their heat wave risk scores range from 33 to 62 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 4.8% of Elmhurst’s area on average, compared with 16% for Oakland as a whole (the 4 Oakland 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 Elmhurst
California’s 2025 Fire Hazard Severity Zone maps do not place any of Elmhurst in a moderate, high or very high zone (CAL FIRE Office of the State Fire Marshal, Fire Hazard Severity Zones). Wildfire smoke and wind-blown embers can still reach areas outside the zones.

Before you rent or buy in Elmhurst
- Look up the exact address on the FEMA Flood Map Service Center; a neighborhood can mix high-risk and minimal-hazard zones.
- Ask the landlord or seller about past flooding and flood insurance claims at the property.
- Get a flood insurance quote early: new NFIP policies usually take 30 days to start (FloodSmart (NFIP): Buy a Flood Insurance Policy).
- Ask which floor the unit is on and where parking, storage and mechanical equipment sit.

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 4, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Alameda County (county code 06001), dataset as of September 8, 2026, retrieved November 4, 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. 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. FEMA National Risk Index: census tracts intersected with the polygon in an equal-area projection; each rating’s share is the share of the polygon covered by tracts with that rating (tracts covering less than 1% are left out; together the tracts used cover 100%). We do not compute a new score. Tracts used: 06001409500 (15%), 06001409700 (15%), 06001409600 (14%), 06001409800 (12%), 06001410300 (11%), 06001410400 (9.6%), 06001410100 (6.1%), 06001409400 (6.0%), 06001410200 (4.9%), 06001409300 (4.1%), 06001408500 (2.3%).
