Comprehensive Plan Transportation Element Element promoting interconnections. Such policies could require that all new subdivision streets be either public or private with public access allowed. Exceptions could be allowed for roadway segments that would channelize traffic through an existing neighborhood or have no potential for providing interconnectivity or through -street benefits (e.g. segments that dead-end into waterbodies, developed properties, or environmentally sensitive areas). In conjunction with policies promoting connectivity, the county should adopt new policies requiring the county to develop traffic calming standards and designs to address concerns about the speed of "cut - through" traffic. • Other Land Use Issues In summarizing the county's existing land use pattern, several issues or problems can be identified, and various opportunities can be noted. One such issue is that there is little mixed use development in the county. Coupled with the division of land uses, this results in auto dependence, produces more trips, results in longer trips, and increases total vehicle miles traveled. Another issue is low densities and vacant land. With the overall low densities in the county, developers' tendencies to build at even lower than allowed densities, and vacant parcels within the existing USA, it is difficult to establish a viable transit system. A third issue is existing strip commercial development. This type of development disperses uses, reduces the efficiency of the roadway system by requiring more curb cuts, limits transit system options, and makes pedestrian trips more difficult. These issues and problems are the result of historic development patterns and not reflective of the policies and initiatives in the county's comprehensive plan. In the future, there is an opportunity to address these issues. Probably the most significant opportunity to address these issues is the continued growth and development projected for the county through this plan's 2030 horizon year. The 2030 land use pattern for Indian River County is reflected in the Future Land Use Element of this plan. As shown on the Future Land Use Map, the 2030 land use pattern is a continuation of the existing development pattern in the county. Both the existing and future land use patterns are characterized by low density, low rise development, commercial/industrial nodes, higher density residential development along high volume roadway corridors, an urban service boundary limiting westward expansion, and a continuation of the current coast -paralleling development pattern. As structured, the future land use plan will have a significant effect on the future transportation system. With the location of the urban service boundary, the future land use plan ensures a compact development pattern that will limit urban sprawl, promote infill development, and manage future growth. From a transportation perspective, the future land use plan can be expected to have various impacts. By limiting westward expansion, limiting urban sprawl, promoting infill development, and encouraging mixed use development, trip lengths will not substantially increase. These shorter trip lengths will result in lower overall system demand, fewer miles of impacted Community Development Department Indian River County 116
