As a new resident to a neighborhood that is still under development, you may be experiencing some challenges that go with living near a construction site. Not only do you have abundant traffic, but the dust and debris that comes with it can be frustrating. You will probably also see some features installed around your neighborhood that you may not recognize or understand their purpose. The Jefferson County Transportation and Engineering Division would like to help you identify and appreciate the value and function of some of these features.
What are Best Management Practices?
Also known as BMPs, Best Management Practices for construction stormwater management are the procedures and features that contractors and builders use to control erosion and sediment transport off of their project sites. Using these procedures and installing these features is a State and local permit requirement for contractors to help minimize the impact of earthwork activities on waterways and water quality of the local environment. These procedures and installations can include easily recognized black silt fencing, street cleaning activities, erosion control blankets, and installation of sediment barriers around storm drain inlets.
Recognizing BMPs and their Function
Sediment barriers at stormdrain inlets are referred to as Inlet Protection. The purpose is to slow sediment-laden stormwater flows and allow for filtration and settling. Once installed, contractors are required to inspect and maintain these features. A design function of these features is that some pooling of water will occur, so do not be alarmed if you notice this.
These installations should not be modified or disturbed, as they will not function as intended. Opening the ends will allow sediment to enter the stormdrain.
In lieu of final landscaping for home lots, builders will often install erosion control blankets and silt fencing to help prevent surface erosion and keep sediment from flowing into the streets.
While a goal of a new homeowner is to install your own selection of landscaping, it is important to preserve these erosion control features in the interim until you are ready to complete landscaping.
Jefferson County is committed to enhancing and protecting the quality of life for our citizens by ensuring that future development continues in a manner that balances social, environmental, and economic needs. If you have questions about the features in your neighborhood or the effectiveness of those features, please call 303-271-8495. Please help us protect our most important natural resource.
