Erosion and Sediment Control
How Does Erosion Affect Our City?
Erosion is the process by which soil and rock are removed from the Earth’s surface by exogenic processes, such as wind or water flow, and then transported and deposited in other locations. This process reduces water quality and can slowly cause the transformation of the natural drainage areas in Lakeland.
Construction sites have challenges with controlling erosion because of the need to break ground, clearing the vegetation thus causing a transformation of the drainage areas. Sediment is the main pollutant on construction sites, averaging a runoff rate that is 10 to 20 times greater than that of agricultural lands.
EXAMPLES OF EROSION CONTROL ISSUES
What is the City of Lakeland Doing?
The City of Lakeland addresses roadside litter from the minimum control measures set forth in our Stormwater Management Plan. The table describes in further detail how each measure is being met with best management practices (BMP).
|Minimum Control Measure||Best Management Practice Activity|
|Public Education and Outreach|
|Public Involvement and Participation|
|Illicit Discharge Detection and Elimination|
|Construction Site Runoff Program|
|Permanent (Post-Construction) Stormwater Management Program|
|Pollution Prevention/Good Housekeeping|
What Can You Do?
There are many things you can do as an individual, family, and community to help reduce Lakeland’s erosion and sediment control issues.
- 1. Please take a look at the Erosion Control Ordinance for specific details regarding required erosion control methods while building in Lakeland.
- 2. Here are some brief quick tips:
- Examine the site carefully before building in order to have the proper design that includes slope, drainage patterns, and soil types.
- Preserve existing vegetation as much as possible.
- Minimize the length and steepness of slopes by benching, terracing, or constructing diversion structures. Landscape benched areas for further stabilization.
- After grading a site, plant vegetation quickly on areas that are not paved or covered.
- Find ways to minimize the use of impervious surfaces.
- 3. Acquire the latest Erosion and Sediment Control Best Management Manual from the TDEC for Low-Intensity Development. Install several of the most suitable practices as part of the site.
- A common way to prevent soil erosion is to plant flowers, trees, and crops over the affected soil. Plants are protective shields that lessen the impact of rainfall, wind, and excessive watering.
- Install matting on the affected soil. Matting is available in wood fibers which make it environmentally friendly and biodegradable. Matting stabilizes the soil while allowing plants, crops, and trees to grow through.
- Utilize mulch and/or fertilizer on top of the soil. This helps water to soak in more slowly, lessening the impact of rainfall, and further stabilizing the soil.
- Install a retaining wall to act as a shield for the soil. It can be built around the garden bed in order to slow the speed of the water after a rain event.
