In Saint Louis, Missouri, proper drainage and erosion control are essential for protecting property, infrastructure, and the environment. Local regulations govern how land development and landscaping projects manage stormwater runoff and prevent soil erosion. Understanding these laws is crucial for homeowners, contractors, and developers to ensure compliance and avoid potential penalties.
Key Regulations Governing Drainage and Erosion Control
St. Louis County Land Disturbance Code
St. Louis County’s Land Disturbance Code outlines requirements for controlling erosion and sediment during construction activities. Projects disturbing one acre or more of land must obtain a Land Disturbance Permit and implement a Stormwater Pollution Prevention Plan (SWPPP). The code mandates the use of best management practices (BMPs) to minimize soil erosion and manage stormwater runoff.
Metropolitan St. Louis Sewer District (MSD) Regulations
The MSD enforces regulations for stormwater management, including design requirements for drainage systems and erosion control measures. Their guidelines ensure that new developments incorporate effective stormwater management practices to protect water quality and reduce flooding risks.
Importance of Compliance
Non-compliance with drainage and erosion control laws can result in:
-
Fines and Penalties: Violations may lead to monetary fines and legal action.
-
Project Delays: Failure to obtain necessary permits or implement required measures can halt construction activities.
-
Environmental Damage: Improper management of stormwater can lead to soil erosion, water pollution, and habitat destruction.
Best Management Practices (BMPs)
Implementing BMPs is essential for effective erosion and sediment control. Common BMPs include:
Silt Fences
Silt fences are temporary sediment control devices commonly used on construction sites to prevent sediment from leaving the site and entering nearby waterways. They consist of a geotextile fabric stretched between stakes and are installed along the contour of the land to intercept and slow down stormwater runoff, allowing sediment to settle out.
Sediment Basins
Sediment basins are engineered structures designed to collect and store stormwater runoff from disturbed areas, allowing sediment to settle before the water is discharged. These basins are particularly effective for large construction sites and are a key component of sediment control strategies.
Erosion Control Blankets
Erosion control blankets are protective coverings made from natural or synthetic materials, such as straw, coconut fiber, or polypropylene. They are placed on slopes and disturbed soils to prevent erosion by stabilizing the soil, reducing the impact of raindrops, and promoting vegetation growth.
Vegetative Cover
Establishing vegetative cover, such as grass, shrubs, or trees, is a long-term erosion control measure that stabilizes soil and reduces runoff velocity. Vegetation acts as a natural barrier, trapping sediment and absorbing water, thereby minimizing erosion.
Fiber Rolls
Fiber rolls, also known as wattles, are cylindrical devices made from straw, coconut fiber, or similar materials. They are placed along contours of slopes to intercept runoff, reduce its velocity, and trap sediment. Fiber rolls are particularly useful in areas where silt fences are not practical.
Infiltration Trenches
Infiltration trenches are shallow excavated trenches filled with gravel or crushed stone that allow stormwater to infiltrate into the ground. They are effective in managing stormwater runoff, preventing flooding, and improving water quality by filtering pollutants.
Filter Strips
Filter strips are areas of vegetation planted between construction sites and water bodies. They function by slowing down runoff, allowing sediment and pollutants to settle before reaching waterways. Filter strips are highly effective in reducing the concentration of nitrogen, phosphorus, and sediment in runoff.
