= Signalization: <br /> We propose to conduct an extensive research and coordination effort prior to the design <br /> of the signalization replacements at the intersections of 58th Avenue (Kings Highway/CR <br /> 613)with 691h Street and CR 510. We will complete a records search for the original traffic <br /> signal plans and inspect the existing signal equipment, observe the intersections, review <br /> the existing signal programming,and obtain the latest counts. We will use this information <br /> to evaluate potential operational issues, establish the optimal signal phasing, and design <br /> the supports and lane configurations at each intersection to accommodate any anticipated <br /> future demand. We have already begun this effort, reviewing a copy of the Indian River <br /> County capital improvement program and FDOT work program. Existing street lighting <br /> fixtures at each intersection will also be documented and recommendations provided for <br /> illumination of the intersections. <br /> We will review the County survey data to ensure that all geometric components that may <br /> affect the design have been identified, including: above and below ground utilities, <br /> landscaping, and roadway elements. We will also obtain subsurface utility explorations to <br /> identify any unmarked utilities in the vicinity of the proposed pole foundations. The <br /> explorations will be completed after determination of the pole locations through <br /> discussions with the County, and coordination with all known Utility companies within the <br /> Right of Way. <br /> Street lighting will be accommodated in the design of the supports for the intersection of <br /> 581 Avenue at 69th Street, which are currently attached to the strain poles. As the <br /> intersection of 58th Avenue at CR 510 already employs lighting mounted to the FP&L <br /> shared-use poles, therefore additional luminaires are not anticipated for that intersection. <br /> A quality signal plan set does not stop with our final approved plan set. Post design items <br /> such as shop drawing reviews and approvals and responses to additional information <br /> requests by the contractor are frequently needed during the construction process. The <br /> team's familiarity and understanding of the FDOT and local agency procurement and <br /> construction process will also provide value for the County's construction team during the <br /> signal construction phase. <br /> Signing and Pavement Markings: <br /> We have a wealth of experience in providing widening, safety and rehabilitation design of <br /> rural roadways. All pavement markings and signing will be designed following the latest <br /> preferences of Indian River County,the MUTCD and the current FDOT indices.All existing <br /> signs and markings will be inventoried and evaluated for conformance with current <br /> standards. Roadway vertical and horizontal geometry will be reviewed to ensure that all <br /> turning movements have adequate sight distance to complete a turning maneuver safely. <br /> Such as at 62nd Ln where tree limbs block the view. We recommend these be trimmed <br /> back to the right of way line to eliminate this.Adequate signage will be designed to provide <br /> advance information for all signalized intersections, provide warning for any side street <br /> connections that may have limited visibility and to inform of any upcoming roadway <br /> changes. Existing signs that meet the design horizontal clearance criteria will be kept as <br /> long as they have proper reflectivity and are in good condition. Other signs in good <br /> 35 <br />
