A. Generally: All subdivisions and development site plans shall delineate the resources listed in section 8-4-2-1, "Protected Resources", of this chapter on a site analysis map that depicts the locations of each resource category along with topography. Such delineation shall be performed by a registered professional engineer.
B. Mapping Criteria: The following criteria shall be used for mapping natural resources:
1. Streams (perennial, intermittent, mapped, and unmapped) with identifiable banks and beds shall have their boundaries set at the top of the bank.
2. Initial identification of the watercourses/water bodies shall be made using the U.S. geological survey quadrangle maps or more accurate information, as available. Field survey verification is required for preliminary plats and site plans in order to establish the location of channelized flow.
3. Woodlands shall be measured at the tree canopy line.
4. Wetlands shall be delineated by the criteria promulgated by the U.S. army corps of engineers.
C. Boundaries: Boundaries shall be drawn as follows:
1. Measurements for boundaries shall be made horizontally, perpendicular from, or radial from any feature or point.
2. Boundaries that are dependent on elevation shall be based upon on site elevations and shall not be interpolated.
D. Topography: Topographic lines shall be at one foot (1') contour intervals. (Ord. 10-001, 1-12-2010)
