JUL 101985 DESCRIPTION & CONDITIONS I BOOK 61 PAGE 4A The Planning Department and the Public Works Division have completed an analysis of the north barrier island's trans- portation system As a result of this analysis, the staff has identified several changes which should be made to the Thorough- fare Plan which is part of the Transportation Element of the Comprehensive Plan. If adopted, these changes would designate additional collector roadways and alter future right-of-way requirements for the affected roads. On February 12, 1985, the Transportation Planning Committee voted 6 -to -1 to recommend approval of these proposed amend- ments. On March 14, 1985, the Planning and Zoning Commission tabled action on this request pending further analysis of the proposed roads on the barrier island. - On April 11, 1985, the Planning and Zoning Commission voted 4 -to -0 to recommend approval of these proposed amendments. On June 24, 1985, the !Planning Department received comments from 'the Treasure Coast Regional Planning Council regarding these proposed amendments. ALTERNATIVES & ANALYSIS The Planning Department and Public Works Division have worked jointly to devise a system of collector roads for the north part of the barrier island. These additions to the Plan are necessary to ensure the acquisition of adequate right-of-way for roads which will provide access to property west of A -1-A that is presently land -locked (has no access to a road) or that has access only to Jungle Trail (classified as a scenic road in the Comprehensive Plan). In preparing this system of roads to serve the north island, the staff considered the alternative of establishing a system of subdivision feeder roads which would not appear on the Thoroughfare Plan map but would be established as these areas developed. However, it was determined that the County will need 80 feet of right-of-way to accommodate both the roadway and the necessary drainage facilities. Designation of these roads as secondary collectors will ensure that 80 feet is obtained, while the feeder road alternative would provide for the acquisition of only 60 feet. A second proposed amendment to the Thoroughfare Plan is the addition of First Street, between Old Dixie Highway and U.S.1, as a secondary collector road. First Street is the only rail crossing between Oslo Road and 4th Street and is carrying an increasing traffic load. In addition, parcels fronting,First Street, as well as other property in this areas are developing as heavy commercial uses, producing a significant amount of heavy truck traffic.. Redesignating First Street as a second- ary collector street would establish 80 feet as the required right-of-way. After the public hearing on March 14, the staff met with some of the property owners affected by the proposed new roads on the island. This meeting resulted in one road being removed from the proposed road system and rearranging the proposed road system south of County Road 510. RECOMMENDATION Based on the above analysis, including the Transportation Planning Committee Commission, staff recommends approval. 34 the recommendations of and Planning and Zoning
