It is the objective of this chapter to control soil erosion and sedimentation caused by development activities in the village. Measures taken to control erosion and sedimentation should be adequate to assure that sediment is not transported from the site by any storm event. The following principles shall apply to all development activities within the village and to the preparation of the submissions required under section 7-4-4 of this chapter:
A. Potential For Erosion: Development shall be related to the topography and soils of the site so as to create the least potential for erosion. Areas of steep slopes where high cuts and fills may be required shall be avoided wherever possible, in the reasonable opinion of the building commissioner, and natural contours shall be followed as closely as possible.
B. Natural Vegetation: Natural vegetation shall be retained and protected wherever possible in the reasonable opinion of the building commissioner. Areas immediately adjacent to natural watercourses shall be left undisturbed whenever possible.
C. Exposure: The smallest practical area of land shall be exposed for the shortest practical time during development.
D. Sediment: Sediment basins, debris basins, desilting basins or silt traps or filters shall be installed and maintained to remove sediment from runoff waters from land undergoing development.
E. Erosion And Sedimentation Control Measures: The selection of erosion and sedimentation control measures shall be based on assessment of the probable frequency of climatic and other events likely to contribute to erosion and on evaluation of the risks, costs and benefits involved.
F. Aesthetics And Maintenance: In the design of erosion control facilities and practices, aesthetics and the requirements of continuing maintenance shall be considered.
G. Increased Runoff: Provision shall be made to accommodate the increased runoff caused by changed soil and surface conditions during and after development. Drainageways shall be designed so that their final gradients and the resultant velocities of discharges will not create additional erosion.
H. Permanent Vegetation: Permanent vegetation and structures shall be installed as soon as practical during development.
I. Elevations: The respective elevations of the tops of foundations, kneewall, retaining walls, stepdowns and similar structures, as well as areas of excavation and/or fill shall be designed, wherever possible, to conform to the natural contours and to minimize interference with the natural or existing drainage patterns.
