road intersections, should be considered in the application of LOS requirements. An additional aspect of the intersection issue is whether an applicant agreeable to making an improvement which would enhance the service level of a link or intersection can be denied development approval because permits for the proposed improvement are denied by an agency such as FDOT having jurisdic- tion over the improvement. Finally, the question has arisen as to how unsignalized intersections should be addressed in a traffic impact analysis and a LOS determination. At its March 24, 1988 meeting, the Planning & Zoning Commission voted unanimously to recommend that the Board of County Commis- sioners authorize the staff to research, draft, and advertise public hearings to consider changes in the transportation system requirements for the site plan section of the Zoning Code. ALTERNATIVES & ANALYSIS The staff assessed these issues and determined that concern relat- ing to these matters was justified. As written, the current ordinance requires that all intersections within the impact area of a project meet minimum LOS standards. The ordinance, however, does not differentiate between signalized .and 'non -signalized intersections in LOS calculation. Since local roads at inter- sections with major roads often operate at LOS E because of left turn movements, those types of intersections will seldom meet LOS standards. Because improvements to meet LOS standards at these intersections would impede flow on the thoroughfare plan roads and because of the limited function of local roads (primarily to provide property access), the application of LOS standards to local road/thoroughfare plan road intersections and to. unsignalized intersections is not desirable. This issue was researched by the staff, and a possible ordinance amendment to resolve the problem was identified. To ensure that LOS standards are applied only to the major road network, several ordinance amendments should be made. These include limiting the LOS consideration to major thoroughfare links (all roads on the thoroughfare plan) and major intersections (the junction of two or more thoroughfare plan roads); adopting a definition of major thoroughfare link, preparing a definition of major intersection, and revising the LOS criteria applicable to unsignalized inter- sections. The proposed changes will add necessary clarification to the LOS requirement in the ordinance. Without these changes there could be unintended adverse effects on site plan applicants. RECOMMENDATION The staff recommends that the Board of County Commissioners authorize staff to proceed with ordinance amendments to clarify components of the transportation network subject to LOS require- ments. ON MOTION by Commissioner Eggert, SECONDED by Commis- sioner Bowman, the Board unanimously authorized staff to proceed with ordinance amendments to clarify components of the transportation network subject to LOS requirements. 5 APR 2 6 1988 600 7'2i1Ei4
