Jones Engineering Solutions presented the drainage analysis for two problem areas on Oct. 15: the Crestmont neighborhood and the Linda/Roseanne/Cravens corridor.
Bob Jones, principal with Jones Engineering Solutions, told council the technical solutions are straightforward but jurisdictional complexity and utility conflicts make the projects costly. For Linda and Roseanne, Jones said the most direct engineering solution is a storm-sewer route down Cravens that would convey runoff to the Willow Waterhole ditch; the watershed in question produces roughly "40-something cubic feet per second" in peak flow and would need a substantially larger outfall than the existing roadside ditches provide.
Jones said the necessary work would likely require relocation of a 12-inch water line and coordination with Fort Bend WCID No. 2, Harris County, Missouri City and TxDOT because the road and outfall cross multiple jurisdictions and utility easements. "There are solutions," Jones said, "but the cost can be a little bit tricky" if Stafford undertakes the whole project alone. He recommended Stafford pursue discussions with the counties, Missouri City and TxDOT to identify cost-sharing opportunities before budgeting for a capital project.
For Crestmont Village, Jones said the main problem is runoff from State Highway 2234 (Texas Parkway) that enters roadside ditches and, in larger storms, overtops inlets and flows into neighborhood streets. He offered two near-term mitigation options: an extension of an existing outfall pipe under TxDOT right of way and a short retaining curb and inlet reconfiguration to reduce water spilling into Crestmont. Jones estimated those combined, near-term fixes at roughly $250,000; he said either measure alone would likely relieve most resident complaints and that the city should start by engaging TxDOT on the pipe extension.
Council members signaled support for pursuing intergovernmental talks. Councilman Guerra offered to help convene county and municipal partners; Mayor and other council members noted the city earlier authorized a $75,000 study and that much of the study money remains unspent. Council directed staff to begin outreach with TxDOT and the county engineers and to return with options and cost estimates at a future meeting.
