The following standards and procedures shall be applied by the Building Inspector and Planning and Zoning Commission in reviewing an application for issuance of a permit in the Protected Hillside Zone.
(a) Maps and Data. Maps and data, either separate or combined, should be provided as follows:
(1) Vicinity map. A print, showing thereon the location of the proposed subdivision and its relationship to adjacent developments, streets and all community facilities which serve or influence it.
(2) Property line map. A drawing, showing bearings and distances of the parcel to be subdivided, location, width and purpose of easements, the name, width and location of abutting streets including location of pavements and sidewalks, structures on the parcel and within 100 feet on adjoining property.
(3) Topographic map. A drawing, showing contours at two foot intervals based on the County datum plane. It shall show approximate direction and gradient of ground slope on immediately adjacent land; indicate subsurface condition of tract; and show watercourses, marshes, wooded areas, isolated preservable trees and other significant features. The topography shall be at the same scale as the preliminary plan. In addition to those requirements this drawing will clearly indicate the limits of the Protected Hillside Zone.
(b) Site Plan. A site plan, superimposed on the topographic and property line map, should show the following:
(1) Improvements plan. Must depict the location of all improvements and impervious surfaces with a clear indication of their relationship to the Protected Hillside Zone, including, but not limited to, all structures, utilities, septic systems, driveways, terraces, tennis courts, pools, etc.
(2) Grading plan. Must show proposed contours and shall list the total amount of cut and fill and shall show the extent of all cut and fill operations.
(3) Profiles. The Village reserves the right to request profiles and/or cross sections that will indicate proposed and existing grades.
(c) Geotechnical Report. A geotechnical report by a qualified geotechnical engineer, that addresses all factors pertinent to site stability, both present and future, will be required by the Village, an shall include the following:
(1) Present stability evaluation. An evaluation of the present stability of the site, based on field exploration that includes test borings, followed by lab testing and stability analysis.
(2) Future stability evaluation. An evaluation of the effect of the planned construction on stability based on the findings in (1) above.
(3) Recommended strategies. Detailed strategies to insure that existing or potential instabilities will be mitigated.
(d) Control of Erosion and Sedimentation. Plans shall meet the standards of Chapter 1329 of the Building Code.
(e) Vegetation Management Report. A vegetation removal and revegetation report shall be submitted by a registered landscape architect, and it will address the following:
(1) Vegetation inventory. A site plan showing the general limits of the various kinds of vegetation (wood lot, meadow, etc.), the locations of all trees 9 inch or greater caliper fourteen inches above ground level (including their genus, species and condition) that are within fifty feet of the limits of the area proposed to be disturbed; location and type of vegetation to be destroyed; location and type of vegetation to be removed due to health, safety and welfare requirements.
(2) Landscape plan. A landscape plan, prepared or approved in writing by a professional registered landscape architect trained and experienced in both the characteristics of plant material and proper procedures for installation, shall be submitted with each application for a Hillside Protection Zone permit.
(f) Gradients. The following standards will be applied to the Protected Hillside Zone:
(1) Driveways. No driveways will exceed a maximum gradient of ten percent (10%).
(2) Embankments. Fill areas may not exceed three feet horizontal to one foot vertical slope.
(3) Excavations. Cut areas may not exceed a two and one half horizontal to one foot vertical slope.
(g) Miscellaneous. Septic systems. Leach beds may not be located on slopes in excess of four feet horizontal to one foot vertical slope.
