FUCK 98 pAu618 the proposed lake, and such zones have been depicted on the plan. The littoral zone planting plan will need to be approved prior to the issuance of a land development permit. 10. Concurrency Management: Long-range planning staff has indicated that a conditional concurrency certificate will be issued for this project prior to the Planning and Zoning Commission's consideration of this item. Thus, all concurrency requirements related to preliminary PD approval have been satisfied. 11. Stormwater Management: As with standard single family subdivisions, the stormwater management plan has been conceptually approved by the public works department, provided that the applicant can document a legal positive outfall. Final review and approval of. the stormwater management plan shall be accomplished through the land development permit process. 12. Thoroughfare Plan: The project has 647' of frontage on CR 510 which is designated on the Thoroughfare Plan as an urban principal arterial requiring 160' of right-of-way. Presently the existing right-of-way width varies between 120' and 1401. The applicant's design accommodates the additional 20' and 40' segments that will be acquired by the county. The county will acquire the full right-of-way for CR 510 as part of this project and compensate the applicant through traffic impact fees and other means. 13. Traffic Circulation: The project will be accessed from CR 510 by the subdivision's main roadway which will provide access to the other streets within the subdivision. The connection to CR 510 will be the only vehicular access point for this subdivision. Staff reviewed the alternative of interconnecting the proposed PD with one or more streets in Oceanaire Heights, and decided not to recommend such vehicular interconnections. This decision was based upon the limitations of the existing street pattern to the east of the subject property and potential negative impacts on Oceanaire Heights. Since Coco Plum is the only through street to SR A- 1 -A, Coco Plum would bear the majority of any traffic as a result of an interconnection with the PD. In staff's opinion, the traffic funnelling effect on Coco Plum would adversely affect the existing homes on that street. As a result of the Traffic Impact Analysis, which was reviewed and approved by the County Traffic Engineering Division, a left -turn lane on CR 510 is required at the project entrance. The left -turn will need to be constructed prior to the issuance of a certificate of completion for phase II. Also, the developer will provide a west bound right -turn lane on CR 510, an improvement which is not a requirement of the Traffic Impact Analysis. The applicant will provide an emergency access interconnection at Coco. Plum Lane, for which the construction details will need to be approved by the Emergency Management Department prior to the issuance of a land development permit. There will also be a pedestrian interconnection between the proposed development and Oceanaire Heights at the emergency access point (Coco Plum Lane). Such an interconnection should benefit residents of both the proposed PD and Oceanaire Heights neighborhoods. 42 JULY 239 1996
