Where does Sachse's stormwater system need improvement?
As a governing municipality, the City of Sachse has a responsibility to its residents to oversee and maintain the operation of the stormwater system, to identify areas where the current stormwater system is ineffective and needs improvement, and to develop a plan to fund and construct improvement projects. The City has developed a list of 24 areas of concern on which to focus improvement efforts in the coming years. As a citizen of Sachse, it is likely that you are familiar with some of these areasâ€”you may avoid a certain street during a storm because it is likely to flood or you may notice a roadside drainage ditch is overgrown with brush and filled with debris.
Below are some areas that have been identified by the City as areas of concern:
Davis Estates Drainage Channel
A concrete-lined drainage channel runs along the county line between Ingram Road and Ty Circle, of the Davis Estates subdivision. The channel discharges into Long Branch stream which is overgrown with plants and debris, causing the area to flood. Regular maintenance and mowing of the point of discharge would likely improve channel performance during a storm event.
- Point of Discharge for Davis Estates Drainage Channel.
A low section of Merritt Road floods during storm events, necessitating road closure. A nearby sewage pump station is also at risk of flooding. Flood control measures need to be put in place to protect existing infrastructure.
- Merritt Road is unnavigable after a storm event.
Jackson Meadow Pond
Stormwater from the Jackson Hills neighborhood discharges into Jackson Meadow Pond through 3 outfall structures. These outfalls are too high, causing water to rapidly spill over the subsurface pipe exit. The rapidly flowing water is causing erosion beneath the concrete headwall. Rip-rap and other erosion controls are required to prevent collapse of the headwall and structural failure.
- Water spills over the headwall into Jackson Meadow Pond.
- Erosion is putting the outfall structure at risk of structural failure.
Several residential neighborhoods in Sachse experience flooding. Backyards along a drainage easement in the Jackson Hills neighborhood fill with water during storm events. The inundation weakens existing backyard fences. Temporary retaining walls have been put in place to delay immediate damage to property, but flooding concerns need to be further addressed with a more permanent solution.
- Fences in the Jackson Hills neighborhood are weakened by flood waters.
- Backyards flood during a storm.
