What this page counts as Newhall
We could not find an openly licensed official boundary for Newhall, so this page uses a census-based area. For this page, Newhall 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 Newhall (feature 272642) and inside the Santa Clarita 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 Newhall. 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.

Flood zones street by street in Newhall
The named streets in Newhall, longest first, with how much of each street’s length inside Newhall lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Newhall; 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. 62 shorter streets are not listed.

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.

By decade
| Decade | Claims | Paid |
|---|---|---|
| 1980s | 2 | $1,186 |
| 1990s | 16 | $9,445 |
| 2000s | 8 | $17,106 |
| 2010s | 2 | $21,462 |
By year of loss
Named flood events with the most claims
- Flooding: 7 claims
- Pineapple Express - Southern: 6 claims

How much is flood insurance in Newhall?
The typical National Flood Insurance Program policy on single-family homes in Newhall costs $1,311 a year: the median of 45 policies that started between September 1, 2025 and August 31, 2026. Half of them cost between $1,079 and $2,250. 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.

Why home insurance costs what it does in Newhall
This section is educational and is not insurance advice.
Flood insurance
ZIP codes do not follow neighborhood lines. This is a ZIP code on at least 5% of the flood claims counted for Newhall, within 10 km of it.
- ZIP code 91321: the median National Flood Insurance Program policy cost for single-family homes was $1,425 a year, the middle of 89 policies that started between September 1, 2025 and August 31, 2026. Half of them cost between $1,082 and $2,232. These policies are priced under Risk Rating 2.0.
- ZIP code 91321: NFIP records list 41 flood claims with a loss year from 1978 through 2011. The claims dataset is as of September 8, 2026.
Fire and wind
- Official state fire hazard maps: Very High 49.7%, High 14.3%, Moderate 8.1%, outside any mapped zone 27.9% of Newhall. The publisher of these maps does not endorse this site.
- USDA Forest Service Wildfire Risk to Communities gives Santa Clarita, CA a Risk to Homes national percentile rank of 0.970, which its methods call Very High (above the 90th percentile). That is the city rating, not a rating of Newhall 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 Newhall
FEMA’s National Risk Index rates heat wave risk for the census tracts that cover Newhall as: “Relatively Low” for 53%; “Very Low” for 47% of the area. Their heat wave risk scores range from 15 to 48 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 5.7% of Newhall’s area on average, compared with 4.6% for Santa Clarita as a whole (the 2 Santa Clarita 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 Newhall
California’s 2025 Fire Hazard Severity Zone maps place about 50% of Newhall’s mapped area in a Very High fire hazard severity zone, 14% in High and 8.1% in Moderate; 28% is outside any 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.

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 November 4, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Los Angeles County (county code 06037), 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: 060379203321, 060379203222, 060379203362, 060379203322, 060379203364, 060379203313, 060379203223, 060379203122, 060379203363, 060379203374, 060379203361. 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: 06037920332 (47%), 06037920340 (13%), 06037920312 (11%), 06037920322 (8.1%), 06037920341 (7.1%), 06037920331 (6.5%), 06037920031 (4.7%), 06037920342 (2.7%). See the methodology.
