Best Management Practices


Management of stormwater in East Baton Rouge Parish is an important aspect of the land development planning process. In 2007, the City-Parish amended the Unified Development Code to incorporate stormwater management regulations. To efficiently and effectively manage and treat stormwater onsite it must start at the site planning stage and carry through to the site design. When dealing with stormwater planners often refer to the term best management practices (BMP). Essentially, these practices are a means of controlling and treating the surface water runoff.

The following diagrams are examples of what property owners can implement to decrease the amount of stormwater runoff and use it, as a resource. These are common best management practices (BMP) that are depicted in a residential setting. For additional information, please refer to the Master Development Program Manual or contact the Planning Commission at (225) 389-3144 or planning@brgov.com.

Bioswale

Bioswales are functional, aesthetic landscape features that utilize stormwater runoff that would otherwise pollute and erode our streams. Runoff is mitigated along the length of the swale, and filtered into the soil through native plant roots and amendments of gravel, sand, and/or compost. The plants reduce the possibility of contaminant pollution that would otherwise proliferate as the water drained across hard surfaces, such as asphalt. Additionally, the use of native plants is a benefit because they thrive in our climate and provide habitat and/or food for local fauna.

Rainwater Cistern

A rainwater cistern is a type of water collection system that captures rainwater from a roof and channels it through gutters to a collection tank. The cistern acts as a storage unit until the water is needed during times of less rainfall or drought. Cisterns may also be referred to, as rainwater catchments or rainwater harvesting systems.

Rain Garden

A rain garden is a shallow depression that is planted with deep-rooted native plants and grasses. The garden should be positioned near a runoff source like a downspout, driveway or sump pump to capture rainwater runoff and detain the water rather than allow it to enter the stormwater drainage system.

Permeable Pavement

Permeable pavement has pores or openings that allow water to pass through the surface and percolate through the existing subsoil. Permeable pavement comes in the form of permeable asphalt, permeable concrete, and permeable pavers. In areas where soils do not drain freely, permeable pavement can be used in combination with subsurface drainage systems, like pipe underdrains or stormwater infiltration trenches to slow runoff and reduce stress on the drainage system.
