Methodology and sources
FloodFireCheck turns public flood data into short neighborhood answers. We do not model risk, score properties, or label any place safe or unsafe. We report what public records show and link to each source.
Neighborhood boundaries
Miami pages use the City of Miami’s published neighborhood polygons (City of Miami, Miami Neighborhoods (ArcGIS feature service)). We prioritize neighborhoods that StrollPlace covers and that have enough flood insurance claims for the numbers to mean something.

Each page states its exact rule and lists its block groups.

Broad areas
Some places people search for, such as Brickell, Coconut Grove, Downtown Miami, the Upper East Side and Little Havana, are common names rather than one official boundary; the City of Miami splits them into several smaller named neighborhoods. For these broad-area pages we combine a stated list of official City of Miami neighborhood polygons into one area and compute every number for the combined area. Each broad-area page lists exactly which neighborhoods it includes and links to their own pages, and those pages link back.
Flood zones
We intersect each neighborhood polygon with FEMA’s National Flood Hazard Layer flood hazard zones (FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels). If FEMA’s map server is unavailable when a Miami page is built, we use Miami-Dade County’s published copy of the FEMA flood zones (Miami-Dade County GIS, FEMA Flood Zone feature layer (county copy of FEMA flood hazard zones)), and the page names the source used. We compute the share of area in each zone using an equal-area projection (EPSG:5070). “High-risk” means the Special Flood Hazard Area (zones beginning with A or V). Zone X is split into shaded (0.2-percent-annual-chance) and unshaded (minimal). We also list the effective date of the FIRM panels involved. Zone definitions follow the FEMA Glossary: Flood Zones.
Flood insurance claims
We download every OpenFEMA NFIP Redacted Claims v3 record for Miami-Dade County, Harris County, Los Angeles County, Orleans Parish, Hillsborough County, Lee County, Lee County, Collier County, Duval County, Escambia County, Bay County, East Baton Rouge Parish, Lafayette Parish, Calcasieu Parish, Charleston County, Mobile County, Harrison County, Harrison County, San Diego County, Sacramento County, City and County of San Francisco, Miami-Dade County, Miami-Dade County, Broward County, Pinellas County, Palm Beach County, Monroe County, Chatham County, New Hanover County, City of Virginia Beach, City of Norfolk, Hudson County, Philadelphia County, District of Columbia, City of Hampton, Broward County, Jefferson County, Galveston County, Nueces County, Broward County, Volusia County, Sarasota County, Pinellas County, Palm Beach County, Orange County, Miami-Dade County, Miami-Dade County, Miami-Dade County, Miami-Dade County, Miami-Dade County, Miami-Dade County, Broward County, Broward County, Broward County, Palm Beach County, Hillsborough County, Hillsborough County, Hillsborough County, Pinellas County, Leon County, Harris County, Harris County, Brazoria County, Fort Bend County, Harris County, Cameron County, Hidalgo County, Hidalgo County, Hidalgo County, Hidalgo County, Webb County, Travis County, Williamson County, Comal County, Bexar County, Dallas County, Tarrant County, Tarrant County, Dallas County, Dallas County, Denton County, Brazos County, El Paso County, Denver County, El Paso County, Jefferson County, Jefferson County, Adams County, Fresno County, Contra Costa County, Orange County, San Diego County, Orange County, Orange County, Los Angeles County, Orange County, Alameda County, San Diego County, Ventura County, Contra Costa County, Santa Clara County, San Mateo County, Orange County, Santa Barbara County, Los Angeles County, Ventura County, Solano County, Ventura County, Okeechobee County, Brevard County and St. Lucie County (FEMA OpenFEMA Dataset: FIMA NFIP Redacted Claims - v3). FEMA redacts addresses; the finest location in the data is the Census block group (2010 boundaries, field censusGeoid). A block group is counted for a neighborhood when at least 25% of the block group’s area is inside the neighborhood, or at least 25% of the neighborhood’s area is inside the block group (U.S. Census Bureau TIGERweb, 2010 Census Block Groups). Because block groups do not follow neighborhood lines, counts can include some properties just outside a neighborhood, and adjacent neighborhoods can share a block group. Block groups along Biscayne Bay include open water, so when we judge how well the selected block groups fit a neighborhood we also measure the fit on land only, using the Census Bureau’s land and water areas for each block group. Paid amounts are the sum of building, contents and Increased Cost of Compliance payments in nominal dollars. Claims only exist where a property had NFIP coverage, so they understate total flooding.
Texas home insurance nonrenewals
Texas pages show, for the ZIP codes on most of the page’s flood claims, how many homeowner-type policies (homeowners, condominium owners, dwelling and mobile home) insurers did not renew or cancelled for a reason on their side, from the Texas Department of Insurance’s HB 2067 data (Texas Department of Insurance, HB 2067 residential property data: actual number of declinations, cancellations and nonrenewals (data.texas.gov); Texas Department of Insurance, HB 2067 residential property data: reasons for declinations, cancellations and nonrenewals (data.texas.gov); Texas Department of Insurance, HB 2067 residential property data: policy counts (data.texas.gov)), which insurers have reported since April 2026. We count every nonrenewal (from the actual-number file) and every cancellation whose stated reasons include at least one on the insurer’s side (from the reasons file); cancellations whose only reasons are nonpayment or the policyholder’s own request are not counted. The reasons file only has notices sent since reporting began, so the totals are a floor. Declined applications are shown separately. Rates are per 1,000 homeowner-type policies in force by TDI’s own count, and only for 10 or more. The Texas Department of Insurance does not endorse this site.
Flood insurance cost
Neighborhood pages show what flood insurance costs there, from FEMA’s NFIP Redacted Policies v3 dataset (FEMA OpenFEMA Dataset: FIMA NFIP Redacted Policies - v3). We take the policies whose 2010 Census block group is one of the page’s block groups and whose policy started in the twelve months ending three months before the page was computed (FEMA publishes with a lag). For single-family homes we report the median and the middle half of the policy cost, which is the premium plus FEMA’s fees and surcharges for the year; where there are fewer than 10 single-family policies we use every residential policy covering one building or unit and say so. With fewer than 10 policies we show no figure. All of these policies are priced under Risk Rating 2.0. Private flood insurance is not in the data.
Why home insurance costs what it does
Where scripts/fetch_insurance.py has been run, the neighborhood page also has a section under that heading. Flood lines use OpenFEMA NFIP Redacted Policies v3 and NFIP Redacted Claims v3 for the ZIP codes already printed on the page (at least 5% of the page’s claims, and a Census ZIP-code centroid within 10 km of the neighborhood). A ZIP or a figure that is missing is left out. Fire and wind lines reuse the page’s existing risk figures, the USDA Forest Service Wildfire Risk to Communities community summary when that file has the place, and a state coastal wind zone only when the state’s own page names the whole county or that community. Market lines are the figures in data/insurance/market.json, each copied from the plan or the state insurance department with its date and URL. The section is educational. It does not sell a policy, name a private insurer, or recommend one.
What these numbers cannot tell you
- Past claims do not predict future flooding.
- Flood maps change; check the current effective map for the exact address on the FEMA Flood Map Service Center.
- Conditions differ by building elevation, floor and street.

Hurricane storm surge, evacuation zones and extreme heat
Pages that show these sections use: NOAA’s National Hurricane Center National Storm Surge Risk Maps (Version 4; Category 1–5 near worst-case inundation at high tide, in 1-ft depth classes on a grid of about 10 m), overlaid on the neighborhood polygon; the official storm surge evacuation zones published by the county (Miami-Dade County’s Storm Surge Planning Zones; the evacuation zones of Hillsborough, Palm Beach, Lee and Collier counties; Sarasota County’s evacuation levels; Pinellas County’s zone for each property parcel, where the shares are of the land in parcels), intersected with the polygon; FEMA’s National Risk Index (Version 1.20.0) hurricane and heat wave ratings and scores for the census tracts that overlap the neighborhood, shown as the share of the neighborhood’s area in each rating, without computing any new score; and the USDA Forest Service’s 2025 NLCD Tree Canopy Cover map (30 m), averaged over the polygon. Sections are shown only where they apply: there are no hurricane storm surge or hurricane evacuation sections for California cities, which have a fire hazard section instead. NHC’s maps are for general awareness at a community level, not for a single parcel, and do not replace official evacuation zones. The National Risk Index is meant for planning and broad nationwide comparisons and is not a substitute for localized risk assessment. Always check the exact address with the county and follow official evacuation orders.
Fire hazard severity zones
California pages show the share of each neighborhood in the state’s 2025 Fire Hazard Severity Zones (Moderate, High, Very High; Local and State Responsibility Areas), intersected with the neighborhood polygon in an equal-area projection. Source: CAL FIRE Office of the State Fire Marshal, Fire Hazard Severity Zones. The zones describe hazard, not the risk to a particular home. CAL FIRE does not endorse this site.
Wildfire hazard potential
Colorado pages show the share of each neighborhood in the classes of the USDA Forest Service’s 2023 Wildfire Hazard Potential map (Very Low to Very High, plus non-burnable land and water; 270 m cells), as counted inside the neighborhood polygon by the Forest Service’s image service. Source: Dillon, G. K. 2023. Wildfire Hazard Potential for the United States (270-m), version 2023, public domain under CC0. The index describes the relative potential for wildfire that would be hard to contain, not the risk to a particular home, and it is not a forecast. The Forest Service does not endorse this site.
Updates
FEMA refreshes the claims dataset about monthly. Each page shows the dataset “as of” date and the date the page was last updated. New neighborhoods are added regularly.

About StrollPlace links
Each neighborhood page links to that neighborhood’s page on StrollPlace, a site that helps people learn an area before they move. We only use StrollPlace links found on StrollPlace’s own Miami pages and confirmed to load directly; where a neighborhood has no StrollPlace page, we link to StrollPlace’s Miami page instead. There are no affiliate links on this site.
Who runs this site
FloodFireCheck is built and run by Swift Agent Sites, which makes websites for real estate agents, insurance agents and movers. It is free to use. Some neighborhood pages carry one listing from a local business, labelled “Sponsored”: the business pays for the spot, it is not a rating or a recommendation, and it has no say over the figures, which all come from public data. Real estate agents whose website Swift Agent Sites built are also listed free, in a box labelled “Swift Agents Network”, on the neighborhood pages they work; that is not a rating or a recommendation either, and it has no say over the figures. How we built it. Our other free tool for people moving is the mover check: a moving company’s federal license and insurance, from the public register.
