What this page counts as Rio Vista

We could not find an openly licensed official boundary for Rio Vista, so this page uses a census-based area. For this page, Rio Vista 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 Rio Vista (feature 295071) and inside the St. Petersburg 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 Rio Vista. Sources: U.S. Census Bureau TIGERweb, 2010 Census Block Groups, National Park Service, National Register of Historic Places boundaries (NRHP polygons) 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 Rio Vista

The named streets in Rio Vista, longest first, with how much of each street’s length inside Rio Vista lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Rio Vista; 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. 110 shorter streets are not listed.

Streets: U.S. Census Bureau TIGERweb, Transportation (primary, secondary and local roads). Flood zones: FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels, retrieved October 28, 2026. Each street is clipped to the area boundary and measured in an equal-area projection. Street lengths are rounded.

Flood zones in Rio Vista

Share of Rio Vista’s mapped area (about 8.995 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 8 to 11 feet. Effective date of the FIRM panel(s) covering it (12103C0207H, 12103C0209H, 12103C0226H, 12103C0228H): August 24, 2021.

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.

Flood insurance claims over time

Claims filed under the National Flood Insurance Program (NFIP) from the 2010 Census block groups that cover Rio Vista. This area is made of whole block groups, so every claim counted here comes from inside it. Only insured properties appear, so these counts understate total flooding.

How much is flood insurance in Rio Vista?

The typical National Flood Insurance Program policy on single-family homes in Rio Vista costs $2,282 a year: the median of 2,318 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $1,743 and $2,966. 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.

How these numbers were made

Area: the census-based definition above, using U.S. Census Bureau TIGERweb, 2010 Census Block Groups, National Park Service, National Register of Historic Places boundaries (NRHP polygons) 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 October 28, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Pinellas County (county code 12103), dataset as of September 8, 2026, retrieved October 28, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 121030244032, 121030244082, 121030244113, 121030244114, 121030244112, 121030244102, 121030244091, 121030244101, 121030244131, 121030244134. 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. Evacuation zones: Pinellas County’s property parcels inside the polygon, each with the zone the county gives it, merged per zone in an equal-area projection (identical stacked parcels counted once); each share is of the land in those parcels, and shares below 0.1% are left out. See the methodology.
