What each hazard means for you

Hurricane Risk
NRI hurricane risk: Bottom 20% nationally (safer than most) for hurricane exposure (county-level, based on historical storm tracks and wind-speed exceedance).
FEMA · National Risk Index (HRCN)
Earthquake Risk
Top 5% most at-risk nationally for earthquake exposure. USGS PGA: 0.748g (site class D). NRI county percentile: Top 5% most at-risk nationally.
USGS · Design Maps (ASCE 7-16) + NRI
Extreme Heat
Long-term heat risk: Top 5% most at-risk nationally (NRI county baseline). This reflects multi-decadal extreme-heat exposure, not the current week's weather.
NOAA · National Risk Index (HWAV)
Flood Risk
County NRI flood risk: Top 5% most at-risk nationally for flood exposure. NFHL parcel query unavailable.
FEMA · National Risk Index
Wildfire Risk
Wildfire risk: Above the national median (top 39% most at-risk). USDA Wildfire Hazard Potential at parcel: Very Low (Class 1/5). County NRI wildfire risk: Top 5% most at-risk nationally. California buyers should independently verify Cal Fire Very High Fire Hazard Severity Zone (VHFHSZ) status; local zoning can impose stricter wildfire requirements than federal parcel data suggests.
USDA · WHP + National Risk Index
Severe Storm / Tornado
Severe storm / wind risk: Top 5% most at-risk nationally. Southern California sees winter storm fronts, straight-line wind, and occasional weak tornadoes, but not the violent tornado climatology of the Great Plains. The high NRI percentile is driven largely by population and property density in Los Angeles County.

What buyers should know
Buying in 90745: a risk primer
Before you write an offer on a home in Carson, understand how climate and insurance costs affect long-term ownership in 90745.
90745 in Carson, California, scores top 10% most at-risk nationally on our composite climate-risk index. That ranking reflects the combined influence of flood risk (100), extreme heat exposure (99), and tornado (98) in this ZIP code. Before writing an offer, buyers should understand which hazard drives the score and how it shows up in insurance premiums and long-term maintenance costs.
The data below is assembled from five federal sources — FEMA (flood and National Risk Index), NOAA (storm history and heat), USGS (seismic design), and USDA (wildfire hazard potential) — and is refreshed quarterly. Use it as a starting point for due diligence, not a substitute for a licensed inspector, structural engineer, or insurance agent.
Flood risk in 90745
The flood risk score for 90745 is 100 (extreme), which is well above the national median. 90745 maps to a FEMA Special Flood Hazard Area or near-SFHA zone in Carson. With FEMA's Risk Rating 2.0 now pricing policies by parcel-level risk rather than just zone, buyers here should expect flood premiums to rise over the life of ownership. A LOMA (Letter of Map Amendment) may help if the finished floor is clearly above the BFE, but the process takes 60–90 days.
For a specific address inside 90745, this score can shift meaningfully. A home on a ridge may have lower flood exposure than one in a valley; a parcel surrounded by irrigated lawn may have lower wildfire exposure than one against open space. The $19 Risk Before Buy report resolves these parcel-level differences and includes a 30-year projection for each hazard.
Heat risk in 90745
The extreme heat exposure score for 90745 is 99 (extreme), which is well above the national median. 90745 experiences severe extreme-heat exposure. This translates directly into higher cooling costs, accelerated roof and HVAC wear, and reduced outdoor usability for parts of the year. Buyers should budget for higher-efficiency cooling and check the age of the existing HVAC system.
For a specific address inside 90745, this score can shift meaningfully. A home on a ridge may have lower flood exposure than one in a valley; a parcel surrounded by irrigated lawn may have lower wildfire exposure than one against open space. The $19 Risk Before Buy report resolves these parcel-level differences and includes a 30-year projection for each hazard.
Tornado risk in 90745
The tornado score for 90745 is 98 (extreme), which is well above the national median.
For a specific address inside 90745, this score can shift meaningfully. A home on a ridge may have lower flood exposure than one in a valley; a parcel surrounded by irrigated lawn may have lower wildfire exposure than one against open space. The $19 Risk Before Buy report resolves these parcel-level differences and includes a 30-year projection for each hazard.
Insurance is where climate risk becomes a monthly payment. In 90745, our directional estimate for a standard homeowners policy plus required hazard coverage is $3,810 – $7,267 per year. That estimate assumes a mid-range home and does not include optional coverages such as earthquake, flood (where not required), or higher wind deductibles.
Relative to local incomes, that premium range equals approximately 5.99% of the Los Angeles County median household income — a severe premium-to-income burden. As a rule of thumb, premiums above 3–4% of household income begin to compress affordability and can reduce the pool of future buyers when you eventually sell.
Buyer action items
- Get carrier quotes early. Ask at least two admitted-market carriers and one surplus-line broker for a homeowners quote that explicitly includes flood risk, extreme heat exposure, and tornado. Do this before the inspection contingency expires.
- Add a climate contingency to the purchase agreement. Our free California-specific contract templates let you make the deal contingent on acceptable insurance premiums, flood-zone status, or seller-provided mitigation documentation.
- Order hazard-specific inspections if the top risks warrant it. In 90745, that may mean a flood-zone determination, a wildfire/defensible-space assessment, a structural/seismic review, or a wind-mitigation inspection depending on which hazards score highest.
