Does Cypress flood?
Answered by Allen Markel, REALTOR®, Texas Premier Realty ·
Short answer
Parts of Cypress are in a mapped FEMA flood hazard area and parts are not. Checking the location of every active Cypress listing against the FEMA National Flood Hazard Layer, 205 of 1,326 homes for sale (15.5%) fall inside a Special Flood Hazard Area (zone AE), where flood insurance is required with a federally backed mortgage. The other 1,121 (84.5%) map to zone X. Zone X means lower mapped risk, not no risk, and two homes on one street can differ. Check the exact address.
What do the FEMA numbers say for Cypress, and what does zone X mean?
We test the latitude and longitude of each active Cypress residential listing against the FEMA National Flood Hazard Layer polygons held in our database. Result: 205 listings in zone AE, all inside a Special Flood Hazard Area, and 1,121 in zone X. A second method, the flood-zone value stored on each listing, gives 203 AE and 1,122 X with one blank, which agrees within two homes. For scale, the same check gives 9.4% for Harris County as a whole and 6.4% for Katy. Cypress Creek and its tributaries run through the area, which is why the mapped areas concentrate in some subdivisions and are absent from others. Zone X is an area FEMA maps as outside the 1%-annual-chance floodplain (the 100-year floodplain). That is a mapped probability, not a guarantee. Heavy rain can flood homes outside the mapped area, and FEMA maps can lag development and drainage changes. Texas requires sellers to answer flood questions on the seller's disclosure notice, including whether the property has flooded and whether it lies in a floodplain. Read that section and ask for any insurance claims history in writing, since claims history attaches to the property, not the owner.
What should I do before making an offer?
First, get the exact flood zone for the address from the FEMA Map Service Center or the flood zone shown on the listing page here. Second, get a flood insurance quote during the option period, because premiums under FEMA's Risk Rating 2.0 are set per property and vary with elevation, distance to water and building features. Third, ask whether an elevation certificate exists. Fourth, review the seller's disclosure and ask about repairs after past storms. A quote on the actual address is the only reliable cost figure, so we do not publish an average premium. Ask your insurer or agent three concrete questions: what the quote is with and without an elevation certificate, whether the policy is written through the National Flood Insurance Program or a private carrier, and what the building and contents limits are. In our data, homes in zone AE are 205 of 1,326 listings, so a Cypress buyer has a real chance of touching a mapped zone when browsing widely. Screening by zone early avoids finding out late in the option period.
