Soil erosion and the resulting sedimentation are a leading cause of water quality problems in Ohio. Every phase of a construction project has the potential of contributing significant quantities of sediment-laden runoff into local streams, creeks, and waterways. Therefore, as a site is developed, all who are associated with the project must do their part to control erosion. Individual lots are no exception.
Why the concern About Erosion and Sediment Control?
· Water quality-Sediment is the number one pollutant, by volume, of surface waters in the State of Ohio. It impacts water quality by degrading the habitat of aquatic organisms and fish, by decreasing recreational value, and by promoting the growth of nuisance weeds and algae.
· Local Taxes-Cleaning up sediment in streets, sewers and ditches increases costs to local and government budgets and subsequently to taxpayers.
· Flooding-Sediment accumulation in ditches, streams, lakes and rivers reduces their capacity, which can result in increased flooding.
· Property Values-Sediment deposits not only impair water quality but also damage property thus reducing its use and value.
PRINCIPLES FOR CONTROLLING LOT EROSION AND SEDIMENTATION
Erosion control is important on any building site regardless of its size. Usually, the principles and methods for controlling erosion and reducing off-site sedimentation are relatively simple and inexpensive. Here are four principles to be followed when developing a building site.
· Evaluate site-Inventory and evaluate the resources on the lot before building. Location of structures should be based, in large part, on the lot’s natural features. Identify trees that you want to save and vegetation that will remain during construction. Also, identify areas where you want to limit construction traffic. Where ever possible, preserve existing vegetation to help control erosion and off-site sedimentation.
· Select and install practices- Determine the specific practices needed and install them before clearing the site. Among the more commonly used practices are vegetative filer strips, silt fence, gravel drives, straw bales and storm water inlet protection.
