Maps and data, either separate or combined, shall be provided and the following additional information shall be provided for final development plan review:
   (a)   Topographic Map. A topographic map that includes a drawing, showing contours at ten 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 shall clearly indicate the limits of the Protected Hillside Zone areas.
   (b)   Development Plan. A development 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 areas, 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 City 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 City, and 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 ensure that existing or potential instabilities will be mitigated.
   (d)   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 development plan showing the general limits of the various kinds of vegetation (wood lot, meadow, etc.), the locations of all trees nine (9) inch or greater in caliper fourteen inches above ground level (including their genus, species and condition) that are within fifty (50) feet of the protected Hillside Zone 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 development within the Hillside Protection Zone areas.
