What this page counts as Oak Hill
We could not find an openly licensed official boundary for Oak Hill, so this page uses a census-based area. For this page, Oak Hill 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 Oak Hill (feature 1375243) and inside the Austin 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 Oak Hill.

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 Oak Hill
The named streets in Oak Hill, longest first, with how much of each street’s length inside Oak Hill lies in FEMA’s high-risk flood zones (the Special Flood Hazard Area, zones A and V).

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 much is flood insurance in Oak Hill?
The typical National Flood Insurance Program policy on single-family homes in Oak Hill costs $512 a year: the median of 12 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $471 and $533. 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.

- Ask when coverage would start. A new National Flood Insurance Program policy generally takes effect 30 days after purchase.

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 October 31, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Travis County (county code 48453), dataset as of September 8, 2026, retrieved October 31, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 484530017381, 484530017491, 484530019151, 484530017371, 484530017492. 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.
