The plan shall contain the following information:
A location or vicinity map
Field delineated and surveyed streams, springs, seeps, bodies of water, and wetlands (include a minimum of two hundred (200) feet into adjacent properties).
Field delineated and surveyed forest buffers
Limits of the ultimate one hundred year floodplain
Hybrid soils mapped in accordance with the NRCS soil survey of the site area
Steep slopes greater than fifteen (15) percent for areas adjacent to and within two hundred (200) feet of streams, wetlands, or other waterbodies.
A narrative of the species and distribution of existing vegetation within the buffer
The buffer plan shall be submitted in conjunction with the required grading plan for any development, and the forest buffer should be clearly delineated on the final grading plan.
Permanent boundary markers shall be installed prior to final approval of the required clearing and grading plan.
Forest buffer for a stream system shall consist of a forested strip of land extending along both sides of a stream and its adjacent wetlands, floodplains or slopes. The forest buffer width shall be adjusted to include contiguous sensitive areas, such as steep slopes or erodible soils, where development or disturbance may adversely affect water quality, streams, wetlands, or other waterbodies.
The forest buffer shall begin at the edge of the stream bank of the active channel.
The required width for all forest buffers (i.e., the base width) shall be a minimum of seventy-five feet, with the requirement to expand the buffer depending on:1) stream order; 2) percent slope; 3) 100-year floodplain; 4) wetlands or critical areas.
a. In third order and higher streams, add twenty five feet to the base width.
Forest Buffer width shall be modified if there are steep slopes which are within a close proximity to the stream and drain into the stream system. In those cases, the forest buffer width can be adjusted.
Method A
| Percent Slope | Width of Buffer |
|---|
| 15%-17% | add 10 feet |
| 18%-20% | add 30 feet |
| 21%-23% | add 50 feet |
| 24%-25% | add 60 feet |
