(a)

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 county's saltwater wetlands and waterways, and to protect water quality and wildlife habitat.

(b)

Wetland, waterway and OCRM critical line buffer depth and setbacks.

(1)

Standards. The following minimum wetland/waterway buffers shall be required:

Minimum buffers (feet). OCRM critical line buffer for zoning districts: RC, RA, R-1, R-1M, R-2, NC = 35.

Minimum buffers (feet). OCRM critical line buffer for zoning districts: R-2M, TC, GC, GI, LI = 15.

Minimum setbacks (feet). Setback from OCRM critical line for zoning districts: RC, RA, R-1, R-1M, R-2, NC = 50.

Minimum setbacks (feet). Setback from OCRM critical line for zoning districts: R-2M, TC, GC, GI, LI = 35.

(2)

Reduction of OCRM critical line setbacks. The planning director shall be authorized to reduce OCRM critical line setbacks to a distance not less than the buffer depth, when deemed necessary by the planning director to accommodate reasonable development of the parcel and when it is determined by the planning director that the setback reduction will not have a significant adverse impact on public health or safety.

(c)

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.

(d)

Lot width. The minimum lot width standards of the underlying zoning district shall apply at the required buffer or setback line.

(e)

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.
