(A) Erosion and sediment control plans shall be prepared according to the following guidelines, as applicable, prior to submission.
(B) Plans shall include appropriate measures and practices for erosion and sediment control, installed in a timely sequence during the development process, and maintained to ensure their proper functioning.
(1) Select land where the drainage pattern, topography and soils are favorable for the intended use. Tracts of land vary in suitability for different uses. Consider the major characteristics of the land area and the kinds of soil in identifying and evaluating potential erosion and sediment problems, and in selecting appropriate control measures and practices.
(2) Expose the smallest practical area of land for the least possible time during development.
(3) When feasible, retain and protect natural vegetation. Save topsoil, where practical, for replacing on graded areas.
(4) Use temporary plant cover, mulching and/or structures to control runoff and protect areas subject to erosion during construction.
(5) Provide for handling the increased runoff caused by changes in topography, soil and surface conditions. Emphasis should be placed on conservation of existing on-site soil. Effective means include the use of diversion ditches, grassed or surfaced waterways and outlets, enlarged and protected drainage channels, grade control structures and effective use of street gutters and storm sewers.
(6) Use sediment basins or other forms of silt traps, where practical, to remove heavy sediment loads from runoff waters leaving the disturbed area.
(7) Install the permanent vegetative cover and the long-term erosion protection measures or structures as soon as practical in the development process.
