Signalization: We propose to conduct an extensive research and coordination effort prior to the design of the signalization replacements at the intersections of 58th Avenue (Kings Highway/CR 613) with 69th Street and CR 510. We will complete a records search for the original traffic signal plans and inspect the existing signal equipment, observe the intersections, review the existing signal programming, and obtain the latest counts. We will use this information to evaluate potential operational issues, establish the optimal signal phasing, and design the supports and lane configurations at each intersection to accommodate any anticipated future demand. We have already begun this effort, reviewing a copy of the Indian River County capital improvement program and FDOT work program. Existing street lighting fixtures at each intersection will also be documented and recommendations provided for illumination of the intersections. We will review the County survey data to ensure that all geometric components that may affect the design have been identified, including: above and below ground utilities, landscaping, and roadway elements. We will also obtain subsurface utility explorations to identify any unmarked utilities in the vicinity of the proposed pole foundations. The explorations will be completed after determination of the pole locations through discussions with the County, and coordination with all known Utility companies within the Right of Way. Street lighting will be accommodated in the design of the supports for the intersection of 58th Avenue at 69th Street, which are currently attached to the strain poles. As the intersection of 5861 Avenue at CR 510 already employs lighting mounted to the FP&L shared -use poles, therefore additional luminaires are not anticipated for that intersection. A quality signal plan set does not stop with our final approved plan set. Post design items such as shop drawing reviews and approvals and responses to additional information requests by the contractor are frequently needed during the construction process. The team's familiarity and understanding of the FDOT and local agency procurement and construction process will also provide value for the County's construction team during the signal construction phase. Signing and Pavement Markings: We have a wealth of experience in providing widening, safety and rehabilitation design of rural roadways. All pavement markings and signing will be designed following the latest preferences of Indian River County, the MUTCD and the current FDOT indices. All existing signs and markings will be inventoried and evaluated for conformance with current standards. Roadway vertical and horizontal geometry will be reviewed to ensure that all turning movements have adequate sight distance to complete a turning maneuver safely. Such as at 621 Ln where tree limbs block the view. We recommend these be trimmed back to the right of way line to eliminate this. Adequate signage will be designed to provide advance information for all signalized intersections, provide warning for any side street connections that may have limited visibility and to inform of any upcoming roadway changes. Existing signs that meet the design horizontal clearance criteria will be kept as long as they have proper reflectivity and are in good condition. Other signs in good 35 P85
