(a) The following uses shall be permitted, provided they do not adversely affect the functions of wetlands within the city:

(b) As an alternative to filling, isolated wetlands may be utilized within the surface water management system of a project as approved by the city.

(c) Maximum residential density within all waters-edge wetlands and isolated wetlands larger than one acre shall be one dwelling unit per 2 1/2 acres.

(d) All subdivision plats and multi-family residential plans shall be reviewed by the building official or the city engineer to determine utilization or protection of wetlands during plat or site plan review.

(e) Any allowed filling of wetlands shall be limited to the structural building area requirements, the 100-year flood elevation requirement for first floor elevations and a single primary access to the on-site structures. The amount of fill and the extent of the filled area shall be the minimum required to accomplish these purposes.

(f) Any person or developer submitting a site plan or subdivision plat for review pursuant to this article shall submit the site plan or subdivision plat to the St. Johns River Water Management District for concurrency evaluation of the impact of the site plan or subdivision plat on wetlands. No building permit or development permit shall be issued unless the St. Johns River Management District has made a determination in the concurrency evaluation process that the proposed development does not require a St. Johns River Water Management District permit and that the proposed development does not cause a loss of wetlands in the city. If a proposed development will cause a loss of wetlands in the city, the St. Johns River Water Management District shall make a determination that proposed mitigation meets the requirements of section 106-31, before any building permit or development permit shall be issued.
