(A) Wetland buffers and setbacks.
(1) Intent. The buffer standards of this section are intended to provide a natural vegetated area between the furthermost projection of a structure, parking or driveway area, or any other building elements and all saltwater wetlands, waterways, and OCRM (saltwater) critical lines. The purpose of these required buffers is to provide a visual, spatial, and ecological transition zone between development and the town’s saltwater wetlands and waterways and to protect water quality and wildlife habitat.
(a) Standards. The following minimum wetland/waterway buffers/setbacks shall be required:
Minimum Buffers/Setbacks (feet) | NRM-25 | AG-5 | AGR | RSL | RSM |
OCRM critical line buffer | 35 | 35 | 35 | 15 | 15 |
Setback from OCRM critical line | 50 | 50 | 50 | 35 | 35 |
Minimum Buffers/Setbacks (feet) | MHS | OR | OG | CN | CC | I |
OCRM critical line buffer | 15 | 35 | 35 | 35 | 35 | 35 |
Setback from OCRM critical line | 35 | 50 | 50 | 50 | 50 | 50 |
(2) Measurement. Required OCRM critical line buffers and setbacks shall be measured from the OCRM critical line, whether the critical line or wetland/waterway is located on, adjacent to, or near the subject parcel.
(3) Lot width. The minimum lot width standards of the underlying zoning district shall apply at the required buffer or setback line.
(B) Prohibited activities. The following activities are specifically prohibited in a buffer area:
(1) Removal excavation or disturbance of the soil, except for minimal disturbance associated with the planting of shrubs or trees for landscaping;
(2) Grassed lawns requiring regular maintenance such as herbicides, pesticides, fertilizers, and frequent mowing;
(3) Gardens, fences or structures, except for permitted crossings;
(4) Paved or other impervious surfaces; and
(5) Destruction or addition of plant life which would alter the existing pattern of vegetation.
