Who handles what
Roadside ditches. Harris County's precinct map puts Atascocita in Precinct 3, whose Road & Bridge page lists Ditch Maintenance. Its Humble Service Center is at 2302 Atascocita Road.
Flood maps. FEMA's effective panels here are dated 2007 and 2014. Harris County's MAAPnext maps remain draft. High & Dry analysis of FEMA's National Flood Hazard Layer (October 10, 2026) puts 4.6% of Atascocita's Census-defined area in the 1% annual chance flood zone and 4.7% in the 0.2% zone: area, not homes.
Channels. High & Dry analysis of HCFCD channel and watershed map layers (October 10, 2026) finds Williams, Cobb, Rogers and Rockpool Gullies and Garners Bayou here. About a third of the area is Greens Bayou watershed, the rest San Jacinto River.
The F-15 study. HCFCD's F-15 feasibility study of San Jacinto River tributaries near Atascocita began in 2021. The HCFCD Q1 2026 bond program report, as published by Reduce Flooding, lists it as "Pausing". It is regional and never sized a yard drain.
Three lot questions
- Where does water enter?
- Where does it stop?
- Where can it lawfully go?
Watch during or soon after rain. A dry-day walk can miss a submerged outlet.
High & Dry can connect Atascocita homeowners with a local drainage contractor. We do not perform construction or claim an outcome before the property is evaluated.

French Drain Installation is the service page once the path is a trench. Kingwood is the area page with the three-maps write-up. What a French drain costs before anyone visits an Atascocita lot is laid out in French Drain Cost in Houston: 2026 Prices Per Foot.
