Stormwater Management Program (SWMP)

 


WHAT IS THE SWMP?

A comprehensive program to manage the quality of discharges from the MS4. Structural Control (or Practice) – A pollution prevention practice that requires the construction of a device, or the use of a device, to capture or prevent pollution in stormwater runoff. Structural controls and practices may include but are not limited to wet ponds, bioretention, infiltration basins, stormwater wetlands, silt fences, earthen dikes, drainage swales, vegetative lined ditches, vegetative filter strips, sediment traps, check dams, subsurface drains, storm drain inlet protection, rock outlet protection, reinforced soil retaining systems, gabions, and temporary or permanent sediment basins. Surface Water in the State – Lakes, bays, ponds, impounding reservoirs, springs, rivers, streams, creeks, estuaries, wetlands, marshes, inlets, canals, the Gulf of Mexico inside the territorial limits of the state (from the mean high water mark (MHWM) out 10.36 miles into the Gulf), and all other bodies of surface water, natural or artificial, inland or coastal, fresh or salt, navigable or nonnavigable, and including the beds and banks of all water courses and bodies of surface water, that are wholly or partially inside or bordering the state or subject to the jurisdiction of the state. Waters in treatment systems which are authorized by state or federal law, regulation, or permit, and which are created for the purpose of waste treatment are not considered to be water in the state.

FAQ
What is storm water?
Stormwater is typically rainwater that flows over surfaces that don’t absorb water, like rooftops, pavement, and packed gravel areas. As it travels toward storm drains, it collects pollutants such as dirt, pet waste, oil, grease, fertilizers, chemicals, and other debris found on the ground. This contaminated water then flows untreated into nearby ditches and canals, ultimately ending up in the Laguna Madre.

 

 

Why protect our stormwater?

Unlike the sanitary sewer system from your home, our storm drain system does not treat the water before it reaches the Laguna Madre. As stormwater flows through the system, it can carry pollutants that may harm fish, wildlife, and contaminate large bodies of water.
