Many are. A significant portion of Sharpstown properties fall within FEMA Zone AE along the Brays Bayou and Keegans Bayou corridors, requiring flood insurance for federally backed mortgages. MAAPnext 2026 preliminary maps are further expanding these boundaries. Even Zone X (Shaded) properties face meaningful risk from flash flooding. Annual premiums range $1,600–$3,500 depending on elevation.
Yes. FEMA’s MAAPnext 2026 preliminary maps have been released for Sharpstown, expanding the Special Flood Hazard Area along both Brays Bayou and Keegans Bayou. New flood models incorporate updated rainfall data and channel conveyance analysis, pulling more properties into the 100-year floodplain. Property owners should review draft maps now, as reclassification could mandate new insurance requirements.
Severely. Sharpstown recorded over 1,800 FEMA flood damage claims after Harvey in August 2017, with Brays Bayou and Keegans Bayou overflowing into dense residential blocks. Inundation depths of 2–4 feet were common, and older drainage infrastructure built in the 1960s was completely overwhelmed. Many properties also flooded during the 2015 Memorial Day and 2016 Tax Day storms.
Dual bayou exposure and outdated drainage. Sharpstown sits between the Brays Bayou and Keegans Bayou corridors, creating overlapping flood risk from two major channels. Drainage infrastructure dating to the 1960s was designed for far less impervious surface than today’s dense development produces. HCFCD conveyance improvements are underway, but the neighborhood remains highly vulnerable to flash flooding events.
It depends on the specific property. Sharpstown’s flood risk varies by proximity to Brays Bayou and Keegans Bayou — properties near channel banks face severe exposure while interior blocks may be in Zone X. A FloodMaps report shows your exact elevation, current and proposed FEMA zone, Harvey damage history, and AI-analyzed risk score.
