What this page counts as Crystal Lake
We could not find an openly licensed official boundary for Crystal Lake, so this page uses a census-based area. For this page, Crystal Lake 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 Crystal Lake (feature 1853244) and inside the Deerfield Beach 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 Crystal Lake.

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.

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

Flood zones in Crystal Lake
Share of Crystal Lake’s mapped area (about 8.867 km²) in each FEMA flood zone, from FEMA National Flood Hazard Layer (NFHL), Flood Hazard Zones and FIRM Panels.

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 Crystal Lake?
The typical National Flood Insurance Program policy on single-family homes in Crystal Lake costs $719 a year: the median of 263 policies that started between August 1, 2025 and July 31, 2026. Half of them cost between $532 and $847. 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 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 29, 2026. Claims: OpenFEMA NFIP Redacted Claims v3 records for Broward County (county code 12011), dataset as of September 8, 2026, retrieved October 29, 2026. Claims are counted for exactly the block groups that make up the area. Block groups used: 120110104051, 120110104053, 120110104072, 120110104052. 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.
