Comprehensive Plan Transportation Element US 1 58t' Avenue - Indian River Boulevard @: Royal Palm Point The Merrill Barber Bridge Through the LRTP and CMP processes, the MPO identified potential future intersection improvements at many of these locations. These potential intersection improvements include adding turn lanes; adjusting signal timing; and making ITS improvements. • Advanced Right -of -Way Acquisition Table 4.9.1 identifies the county's advanced right-of-way needs for roadways through the year 2030. As indicated, almost all Thoroughfare Plan roadways will eventually require additional right-of-way acquisition by the county. According to the 2030 LRTP, right-of-way costs to complete the 2030 Roadway Improvements Plan are approximately $128.8 million. To ensure that sufficient right-of-way is available for future construction projects, the county should develop a balanced capital improvement program that includes advanced right-of-way acquisition funding along with construction funding. Because of the increase of low intensity, non -urban uses outside of the urban service area, the county needs to ensure that this kind of development does not preclude the eventual extension of the roadway grid system. If the future land use map is eventually amended or if the urban service area is extended, maintaining adequate access in these areas will be critical in connecting the county system of roads. For identifying and protecting essential right-of-way, the primary mechanism is the Extended Roadway Grid Network (Figure 4.10). As development continues, this grid network should be protected by requiring appropriate land dedication through the site plan and subdivision approval process. • Other Needs Besides the Cost Feasible Plan roadway capacity improvements and intersection and right-of- way needs, there are other traffic circulation system needs that must be addressed. These other needs include bridge improvements, resurfacings, and safety projects. Cost estimates for these improvements were obtained from programmed and proposed project listings; from historic costs per lane mile; and from growth projections. These costs are listed alongside Cost Feasible Plan improvements in the transportation capital improvements program (Table 4.9.4). • Cost Feasible Plan Improvements The MPO's 2030 cost feasible roadway improvements plan is depicted in Figure 4.8 (Table 4.9.3). When all cost feasible improvements are completed, the roadway network laneage in Indian River County will have increased substantially, as shown in Figure 4.9. Because of this additional capacity, future roadway level of service will be maintained above the adopted level of service as for those roadways. This is demonstrated on figure 4.9A.
