§ 23-210. Buffer zones.

(a)

The natural buffer zone for a legally existing lot of record which existed prior to the effective date of the ordinance from which this article derived and which was naturally vegetated as of January 1, 1990, shall be determined as follows:

(1)

The wetland line shall be delineated.

(2)

A natural buffer width of seventy-five (75) feet shall be added to the upland side of the wetland delineation.

(3)

The applicant may use the methodology for newly created lots of record (paragraph (c)) if this application demonstrates that a smaller natural buffer width is appropriate.

(b)

The buffer zone for a legally existing lot of record which existed prior to the effective date of the ordinance from which this article derived and in which the natural vegetation was removed prior to January 1, 1990, shall be determined as follows.

(1)

A fifteen-foot buffer shall be retained adjacent to the wetland line.

(2)

Site-specific stormwater treatment, such as a swale/berm system and erosion-control measures, shall be required adjacent to the upland side of the fifteen-foot buffer.

(c)

Natural buffer zones for any lot of record created after the effective date of the ordinance from which this article derived shall be based on guidelines contained in "An Evaluation of the Applicability of Upland Buffers for the Wetlands of the Wekiva Basin (Center for Wetlands, Brown and Schaefer, 1987)" and "Buffer Zones for Water, Wetlands, and Wildlife (Center for Wetlands; Brown, Schaefer, and Brandt; 1989)." The applicant may propose alternate methodology, but such methodology may be subject to verification and must address the following:

(1)

Erodibility of soils upland of the wetland line.

(2)

Depth of the watertable below the soil surface in the zone immediately upland of the wetland line.

(3)

Habitat requirements of aquatic and wetland-dependent wildlife based on:

a.

Habitat suitability.

b.

Spatial requirements.

c.

Access to upland or transitional habitat.

d.

Noise impacts.

(d)

All new commercial and industrial development must follow the buffer methodology contained in paragraph (c) above.
