Duncanville council moves to adopt drainage master plan; staff urged to explore homeowner cost-share options
Summary
Public works presented a drainage master plan recommending a phased capital program and stream-condition assessment; council indicated support for adopting the plan and asked staff to further study cost-share, loan, and improvement-district options to help private-property owners address erosion.
Shahad Mohammed, assistant director of public works, told the City Council that the drainage master plan and accompanying stream-condition assessment lay out a phased capital-improvement program and identify grant opportunities and design standards to address stormwater and erosion vulnerabilities across the city.
Mohammed summarized the study’s two parts: systemwide stormwater planning that produced prioritization and planning-level cost estimates, and a targeted stream-condition assessment focused on critical creek stretches and asset protection. "We developed a phased capital improvement program, specifically addressing critical drainage deficiencies," Mohammed said.
Staff also called out recurring complaints about creek erosion that affect private property. Mohammed presented four possible approaches for addressing erosion on private property: (1) keep the current practice (property owner responsibility except where public safety or city assets are threatened), (2) create a cost-share assistance program (e.g., 50/50 or 70/30 city-owner splits with an application process), (3) a loan/assistance program administered by the city but repaid by owners, or (4) a special-assessment or improvement-district model in which a corridor of property owners shares project costs.
Council members asked how the plan aligns with regional efforts and how projects were prioritized. Mohammed said the team coordinated with Dallas County’s inland port study and included those projects in prioritization; projects that scored lower still appear in the recommended list. He said prioritization considers asset-protection risk (water, sewer lines) and the potential cost of failure.
Council signaled a consensus to move forward with adoption of the drainage master plan while directing staff to return with more detailed options for private-property assistance, qualification criteria, budget impacts, and potential grant strategies.
