• trees cannot be feasibly removed from the interior of the site due to the presence of the existing lake. Removal from adjacent properties cannot be required technically, and may not be feasible in certain cases where access would be through someone's back yard. Therefore, staff believes that the waiver request is justifiable. 14. Buffer & Setbacks: Based upon the compatibility matrix in LDR section 915.16, no special PD related buffers are required other than the normal, minimum 25' PD perimeter building setback. That 25' building setback is depicted on the PD plan along the entire perimeter of the project. However, the county's agriculturelresidential buffer applies where proposed Lot 6 abuts an existing active grove. Therefore, a Type "B" buffer with a 6 high opaque feature is required along the west boundary of Lot 6. As an alternative, the applicant can work with the owner(s) of the adjacent grove and obtain an easement prohibiting active agricultural operations over the portion of the grove that abuts Lot 6. Such an easement could prohibit active agricultural operations, such as spraying, so as to protect the residents of Lot 6. Such an easement should have a minimum width of 60', a distance which corresponds to the separation between Lot 6 and active agricultural uses that would occur if there were a local road right-of-way between Lot 6 and the grove. Where there is an intervening right-of-way, the agriculturd residential buffer requirements do not apply. Therefore, prior to issuance of an LDP or LDP waiver, the applicant must either depict the agricultural/residential buffer on the PD plans or commit to the alterative arrangement for an easement. Any such easement arrangement will need to be approved by staff and finalized prior to final plat approval. 15. Caribbean Fruit Fly Host Plant: The county has adopted a comprehensive plan policy prohibiting Caribbean fruit fly host plants in residential PDs, such as this project, that are close to areas of active groves. Therefore, prior to or via the project's final plat approval, host plant prohibitions shall be included in covenants and restrictions that affect the project site. 16. Concurrency: The applicant has obtained a conditional concurrency certificate which satisfies concurrency requirements related to the special exception use and preliminary PD plan/plat requests. Therefore, all concurrency requirements related to special exception use and preliminary PD phuVplat approval have been satisfied. 17. Waivers: As allowed through the planned development special exception use process, the applicant is permitted to request waivers from certain normally applied provisions of the land development regulations. The requested waivers are as follows: Allow the standard entrance road/cul-de-sac right-of-way width to be used even through a small entrance road median is to be constructed. (Note: normally, the right-of-way would be required to be expanded the width of the median.) 2. Reduce roadway pavement widths from 20' to 18'. Keep existing Australian pines along the entire western boundary of the project site, and those located between the lake and the south and east perimeter of the overall site. 4. Eliminate any cul-de-sac or "T" turn around at the ends of the east and west branch roadways. Such roadways would simply terminate at the driveways for Lots 1 and 6, respectively. Due to the low density and low traffic generation characteristics of the project, the efforts to design improvements so as to minimally impact existing vegetation, and for reasons previously stated regarding the Australian pine issue, staff has no objections to these requested waivers.
