Erosion and Sedimentation control is the prevention of erosion on construction sites and the discharge of sediment-laden water (muddy water) onto adjacent properties and roads.
For small disturbance areas, the contractor must install a silt fence along the perimeter of the property and a tire scrubbing rock construction entrance.
For large disturbed areas, a sediment basin or trap, coupled with silt fence and rock construction entrance must be installed at the bottom of the construction site to collect and store the sediment laden water to settle the sediment out of the water, and eventually discharges clean water from the sediment basin or trap.
These above listed erosion controls, coupled with a detailed, step-by-step, sequence of construction, adequately prevent erosion and the discharge of sediment onto downstream adjacent properties.
D.L. Howell has years of experience with various Conservation Districts and at the Department of Environmental Protection, we have developed beneficial professional relationships with the individuals reviewing the proposed Erosion & Sedimentation (E&S) Control Plans, and stay up-to-date on the latest E&S regulations and design techniques.
Previous Erosion and Sedimentation Control Plan Projects
The Crane Tract
A 573 Unit Townhouse, Single-Family and Apartment Subdivision located in West Caln Township, PA. The design included the preparation of construction documents and calculations for: 15 dedicated roadways with all site infrastructure to provide utility service to the development; six above-ground infiltration basins and one underground pipe storage infiltration facility; lot grading for the proposed buildings; a five-miles waterline and sanitary sewer force main to extend public utility service to the development, the site entrance onto a state highway with the intent of acquiring a Highway Occupancy Permit, and phasing drawings specifically indicating the improvements to be constructed during the four phases of the development.
Dash Enterprises Auto Dealership
This 28,600 square foot Auto Dealership located in West Goshen Township, Chester County included the use of a super silt fence, a temporary diversion swale, inlet protection, erosion control blanket and a sediment basin.
Whitegate Farms Subdivision
A 69 lot residential subdivision in which we prepared grading permit plans for all the individual building permits. Plans included for the most part a typical on-lot erosion control layout including 18 to 30 inch silt fencing around the perimeter of each lot, topsoil stockpiling, rock construction entrance and construction sequencing.
