What this page counts as Round Lake

We could not find an openly licensed official boundary for Round Lake, so this page uses a census-based area. For this page, Round Lake means the 2010 Census block groups whose center lies inside the National Register of Historic Places boundary of the Round Lake Historic District (National Park Service) and inside the St. Petersburg city limits (U.S. Census Bureau). 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 Round Lake. 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.

Neighborhood figures are averages. Our address check looks up the FEMA flood zone and the hurricane evacuation zone at one address, from the same public maps: check if your address is in a flood zone.

Flood zones street by street in Round Lake

The named streets in Round Lake, longest first, with how much of each street’s length inside Round Lake lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V). Length is the part inside Round Lake; 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. 9 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 Round Lake

Share of Round Lake’s mapped area (about 0.969 km²) in each FEMA flood zone, from FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels. Effective date of the FIRM panel(s) covering it (12103C0217H, 12103C0219H): 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.

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: 121030235003, 121030235001. 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.
