The average density permitted in each planned unit development shall be established
by the city commission upon recommendation of the planning and zoning board. The criteria
for establishing an average density shall include existing zoning, adequacy of existing
and proposed public facilities and services, site characteristics, and the recommended
density of the adopted future land use plan involving the area in question. In no
case shall the maximum density permitted exceed ten dwelling units per gross acre
unless approved by the city commission as a medium/high density multifamily complex
that provides a high degree of amenities such as gated entranceways, pools, passive
and active recreational areas for both adults and for children, fitness centers, indoor
basketball and/or racquetball courts, covered parking, and has heavily landscaped
grounds with semi-mature canopy trees.
