• There are several other P D projects, including Kenwood Village and the Oaks of Vero, which have employed similar tree preservation/micro siting techniques. The techniques used for Ansley Park will be slightly different due to the density of trees on certain lots. For Ansley Park the applicant has committed to saving as many trees as possible on the individual lots. 14. Waivers: The PD plan proposes to reduce the minimum lot size from the RS -3 zoning district required 12,000 square feet to 9,000 square feet. The PD plan also proposes to reduce the minimum lot width from 80' to 75', the minimum right-of-way from width 50' to 40 the minimum front and rear yard setbacks from 25' to 20', and the minimum side yard setback from 15' to 7.5 . These requested waivers are mitigated by proposed buffers, conservation tracts, increased minimum open space, common recreational amenities, and increased tree preservation. In addition, the parameters are generally consistent with the adjacent Grovenor Estates development. It should be noted that the land use for the site is L-2, which allows up to 6 units/acre; however, the subject and surrounding residential sites are all zoned RS -3 (up to 3 units/acre) The Grovenor Estates lots, as platted, do not meet RS -3 size and dimension requirements. Therefore, under the LDRs, the less stringent RS -6 setbacks apply The project density of 1.79 units per acre is consistent with modern conventional (non -PD) RS -3 subdivisions. These generally range in density from 1.5 to 2.6 units per acre depending upon how stoiuiwater management is designed. In this case, the applicant's design trades some lot area for common area (preservation areas and perimeter buffers). With a conventional (non -PD) RS -3 subdivision, the common area would instead be part of individual lots. The result would be bigger lots but less common area — although the density would be the same under either option. Similar to the Kenwood Village PD design, this plan incorporates perimeter buffers which provide a compatibility measure to compensate for the smaller lots on the perimeter. In essence, the applicant's design does not spread the 1.79 units/acre over as much land as a conventional (non -PD) RS -3 subdivision would, but provides a more compact developed area. The preservation area, perimeter buffers and density of 1.79 units/acre provide a development design which is compatible with the adjacent area. The requested waivers are summarized and compared in the table below: JULY 16, 2002 -3J- • RS -3 Minimum Standard Proposed Ansley Park Minimum Standard Lot Size 12,000 sq. ft. 9,000 sq.ft. 8,040 sq. ft Lot Width 80 ft. 75' 66 ft Front and Rear Yard Setback 25 ft.
