(A) Whenever feasible, natural contours should be followed as closely as possible in areas of steep slopes where high cuts and fills might otherwise be required, so that the design of every subdivision is consistent with the natural limitations presented by topography and soil, and so as to create the least potential for soil erosion.
(B) Wherever possible, natural vegetation should be retained and protected and areas immediately adjacent to natural watercourses should be left undisturbed.
(C) The smallest practical area of land should be exposed for the shortest practical time during development.
(D) During development, the Subdivider/Developer shall install temporary erosion control measures to prevent siltation of adjacent streams, roads, and property.
(E) The Subdivider/Developer shall install and maintain appropriate permanent devices, such as sediment basins, debris basins, desilting basins, silt traps, filters, rip rap, or energy dissipaters, in order to prevent long term erosion and siltation and to remove sediment from run- off waters.
(F) The Subdivider/Developer shall select erosion and sedimentation control measures based upon an assessment of the probable frequency of climatic and other events likely to contribute to erosion, and upon an evaluation of the risks, costs, and benefits involved.
(G) In the design of erosion control facilities and practices, aesthetics and the requirements of continuing maintenance should be considered.
(H) Provision shall be made to accommodate the increased runoff caused by changed soil and surface conditions during and after development. Drainage ways should be designed so that their final gradients and the resultant velocities of discharges will not create additional erosion.
(I) Permanent vegetation and structures should be installed as soon as practical during development, and in no case exceed more than ninety (90) days.
