(a) Submittal Procedures. For the Village of Franklin's approval of a grading plan for erosion and sediment control, the applicant shall furnish a detailed estimate of cost and three sets of the subdivision and/or site grading plans. The Village Engineer shall review the estimate and plans for conformity to the principles set forth herein, after which the Village Engineer will return one of the three sets with appropriate comments. After making any changes requested on the set of plans returned to him or her, the applicant shall then submit four sets of revised plans to the Village for final approval. The Village Engineer shall then review these revised plans for conformity to the comments mentioned heretofore, and, if the changes have been properly made, will retain three copies for the Village records and return one approved copy to the applicant.
(b) Design Standards. In order to provide effective erosion and sediment control, practical combinations of the following technical principles shall be applied to the erosion control aspects of the grading plan. All soil erosion control measures shall be in accordance with Oakland County Drain Commissioner standards and will require permission from the County, where applicable:
(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) Temporary vegetation and/or mulching should be used to protect critical areas exposed during development.
(4) Sediment basins (debris 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 runoff caused by changed soil and surface conditions during and after development.
(6) The permanent final vegetation and any structures should be installed as soon as practical in the development.
(7) The development plan should be fitted to the topography and soil so as to create the least erosion potential.
(8) Wherever feasible, natural vegetation should be retained and protected.
