What this page counts as Willow Glen
We could not find an openly licensed official boundary for Willow Glen, so this page uses a census-based area. For this page, Willow Glen 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 Willow Glen (feature 1660183) and inside the San Jose 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 Willow Glen.

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

Flood zones in Willow Glen
Share of Willow Glen’s mapped area (about 8.032 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 96 to 120 feet. Effective date of the FIRM panel(s) covering it (06085C0233H, 06085C0234H, 06085C0241H, 06085C0242H, 06085C0253H, 06085C0261H): May 18, 2009.

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 Willow Glen?
The typical National Flood Insurance Program policy on single-family homes in Willow Glen costs $1,813 a year: the median of 717 policies that started between September 1, 2025 and August 31, 2026. Half of them cost between $928 and $2,166. 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.

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 Willow Glen
FEMA’s National Risk Index rates heat wave risk for the census tracts that cover Willow Glen as: “Relatively Moderate” for 68%; “Relatively Low” for 32% of the area. Their heat wave risk scores range from 41 to 72 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 12% of Willow Glen’s area on average, compared with 2.4% for San Jose as a whole (the 3 San Jose 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 Willow Glen
California’s 2025 Fire Hazard Severity Zone maps do not place any of Willow Glen 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.

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 Santa Clara County (county code 06085), dataset as of September 8, 2026, retrieved November 4, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 060855023012, 060855018002, 060855018001, 060855025003, 060855025001, 060855018003, 060855017002, 060855017004, 060855018004, 060855024005, 060855031231, 060855031132, 060855024002, 060855024007, 060855024003, 060855031211, 060855031131, 060855023021, 060855024006, 060855024004. 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: 06085502400 (30%), 06085501800 (18%), 06085503121 (11%), 06085503113 (9.1%), 06085502301 (8.6%), 06085502500 (8.0%), 06085501700 (6.3%), 06085502302 (4.3%), 06085503123 (3.7%), 06085501902 (1.5%).
