Comprehensive Plan Transportation Element <br /> For roadways, the agency with jurisdiction is generally responsible for maintaining or improving <br /> the facility. Therefore, a pothole in a local .road in Vero Beach would be the City of Vero <br /> Beach's responsibility to repair, while congestion on US 1 might require the State Department of <br /> Transportation to construct additional lanes for traffic. Under ISTEA, the Intermodal Surface <br /> Transportation Efficiency Act of 1991, and subsequent Federal Highway bills, funding for <br /> roadway improvements, whether widening or re-surfacing, is less dependent on jurisdictional <br /> responsibility than on functional classification. With ISTEA, federal Surface Transportation <br /> Program funds can be used on any federally classified road, except for local roads and rural <br /> collectors, regardless of jurisdictional responsibility. <br /> While Table 4.7.1 identifies the jurisdictional responsibility of each thoroughfare plan roadway <br /> within the county, Figure 4.2.1 graphically depicts the jurisdictional responsibility for each road <br /> on the major roadway network. As these indicate, the major inter-county roadways, including <br /> Al A, SR60, I-95, and US 1, are state roads. Similarly, roads such as Indian River Boulevard, <br /> CR 512, Roseland Road and others that extend through a municipality into the unincorporated <br /> area are generally county roads. I-95, SR 60 west of I-95, and the Florida Turnpike are Florida <br /> Intrastate Highway System (FIHS) roads. <br /> Functional Classification <br /> Functional classification is the process by which roads are grouped into different categories. <br /> Generally, roads are classified according to the degree of mobility and/or land access provided, <br /> with different roadway facilities providing different levels of mobility and accessibility. <br /> Generally, roads with a lower functional classification provide access to adjacent land uses, such <br /> as residential areas, employment centers, and commercial centers, with low levels of mobility. <br /> Roads with a higher functional classification are considered limited access facilities with high <br /> levels of mobility. <br /> For example, the Interstate Highway System is a sub classification of the highest functional <br /> class, principal arterials, and is characterized by long distance travel patterns and relatively high <br /> speeds. Since interstates are limited access facilities, provisions are not made for direct land use <br /> access from the Interstate system itself. Instead, interchanges with other highways are provided <br /> at discrete intervals, and land access is generally provided from those highways. <br /> According to state law, comprehensive plans must depict the existing FDOT roadway functional <br /> classification on the existing traffic circulation map or map series. For roadways in Indian River <br /> County, existing and future functional classifications are depicted in Figures 4.3.1 and 4.3.2 <br /> respectively. <br /> From a planning standpoint, functional classification is important for four reasons: <br /> 1. Functional classification groups together those facilities requiring the same level <br /> of technical, managerial and financial competence for design, construction, <br /> maintenance and operation; <br /> Community Development Department Indian River County 22 <br /> APPENDIX A—Transportation Amendments <br />
