Runoff at Your Site

San Antonio grows, sustains and innovates in part through new developments. As our population increases, so does the need for residential/commercial developments. Construction contractors work with the City of San Antonio, San Antonio Water System and other entities to establish and monitor construction activities. Yet the need to reduce and prevent pollutants from contaminating storm water runoff is ever-present.

Construction contractors accomplish this through implementation of Best Management Practices (BMPs) across their operations, procedures, and employee training/education. San Antonio’s Phase I MS4 storm water discharge permit regulates and prohibits nonpoint source pollutant infiltration and contamination of area rivers, creeks and channels as a result of commercial construction operations and activities.

Operational Priorities for Construction Contractors

River-friendly construction and development activities successfully demonstrate the following priorities with regard to standard operating practices at work sites:

  • Maintaining adequate erosion and sediment controls at construction sites so as to reduce/prevent sediment discharges in storm drains and runoff.
  • Minimizing tracking of mud, sediment and loose material into streets/down storm drains caused by heavy construction equipment on-site through clear establishment of construction vehicle entrances/exits and paths free of soil.
  • Maintaining adequate storage/cover of construction materials and management of refuse piles so as to minimize/prevent material wastes and debris from being blown or swept into streets/storm drains by wind/rain. Designating storage areas in spaces away from storm drain inlets or naturally occurring water channels where runoff can enter.
  • Protecting surrounding natural environmental features and preserving existing vegetation or installing new vegetation as much as possible in order to help filter/slow storm water runoff.
  • Establishing efficient construction phasing and scheduling of construction activities in order to minimize loose soil exposure to weather conditions.
  • Practicing source reduction by ordering/using only the amount of construction materials needed to complete the project.
  • Mitigating surface runoff amounts at construction site areas by blocking site-generated runoff flows through use of berms, drainage ditches, etc. to channel site runoff to areas away from streets/storm drains/natural waterways.
  • Educating construction workers/managers about storm water runoff management and roles/responsibilities; monitoring site runoff management efforts in order to ensure quality control.

About Remember the River

Remember the River is a community campaign focused on nonpoint source pollution prevention outreach and education. The campaign is led by the City of San Antonio.

All campaign education and outreach efforts are conducted in compliance with educational/outreach guidelines established under a TPDES Phase I Municipal Separate Storm Sewer System (MS4) discharge permit regulated by the Texas Commission on Environmental Quality.
