(A) In the event that any developer shall intend to make changes in the contour of any land proposed to be subdivided, developed, or changed in use by grading, excavating or the removal or destruction of the natural topsoil, trees, or other vegetative covering thereon the same shall only be accomplished after the owner of said land or his agent has submitted to the Building Commissioner for approval a plan for erosion and sedimentation controls, unless there has been a prior determination by the Building Commissioner that such plans are not necessary.
(B) Such plans shall contain adequate measures for control of erosion and siltation where necessary, using the guidelines and policies contained herein.
(C) The Building Commissioner shall review these plans as submitted, and shall take necessary steps to insure compliance by the developer with these plans as finally approved.
(D) Requirements.
(1) Three sets of plans for the control of erosion and sedimentation shall be submitted to the Building Commissioner at the time the final development drawings are submitted.
(2) Measures to be taken to control erosion and sedimentation shall be described and provided for in the construction agreement and the estimated cost of accomplishing such measures shall be determined by the Building Commissioner.
(3) At the building permit application stage, a review will be conducted to insure conformance with the plan as approved.
(4) The Building Commissioner shall make a continuing review and evaluation of the methods used and the overall effectiveness of the erosion and sedimentation control program.
(E) Suggested control measures. The following control measures should be used for an effective erosion and sediment control plan:
(1) The smallest practical area of land should be exposed at any one time during development.
(2) When land is exposed during development, the exposure should be kept to the shortest practical period of time.
(3) Where necessary, temporary vegetation and/or mulching should be used to protect areas exposed during development.
(4) Sediment basins (debris basins, desilting basins, or silt traps) should be installed and maintained to remove sediment from runoff waters from land undergoing development.
(5) Provisions should be made to effectively accommodate the increased run-off caused by changed soil and surface conditions during and after development.
(6) The permanent final vegetation and structures should be installed as soon as practical in the development.
(7) The development plan should be fitted to be the topography and soils so as to create the least erosion potential.
(8) Wherever feasible, natural vegetation should be retained and protected.
