Given those conditions, the number of trips associated with this <br />request was determined by taking the total number of residential <br />units (37) allowed under the proposed land use, applying ITE 's <br />1.012 p.m. peak hour trips per residential unit factor to get total <br />peak hour trips, and applying the ITE residential use p.m. peak <br />hour inbound factor of 65% to the total p.m. peak hour trips for <br />the use to get the west bound (peak direction) peak hour volume of <br />trips for the site. The same methodology was used to obtain the <br />site's p.m. peak hour exiting volume; however, a 35% outbound <br />factor was used instead of the 65% inbound factor. Using a <br />modified gravity model and a hand assignment, these trips were then <br />assigned to -roadways on the network. <br />As a result of this assignment, two volumes were obtained for each <br />impacted roadway segment. These volumes represent the p.m. peak <br />hour volume for each direction of the roadway. Using the volume <br />assigned to the peak direction of each roadway, a capacity <br />determination was made for each segment. This capacity <br />determination involved comparing the assigned volume to the <br />segment's available capacity. <br />Capacities for all roadway segments in Indian River County are <br />calculated and updated annually, utilizing the latest and best <br />available peak season traffic characteristics and applying Appendix <br />I methodology as set forth in the Florida Department of <br />Transportation (FDOT) Level of Service (LOS) Manual. Available <br />capacity is the total capacity less existing and committed traffic <br />volumes; this is updated daily, based upon vesting associated with <br />project approvals. <br />Based upon staff analysis, it was determined that 8th Street and <br />the other impacted roadways serving the project can accommodate the <br />additional trips without decreasing the existing level of service. <br />Impacted roadways are defined in the County's Land Development <br />Regulations as roadway segments which receive five percent (5%) or <br />more daily project traffic or fifty (50) or more daily project <br />trips, whichever is less. <br />The table below identifies each of the impacted roadway segments <br />associated with this proposed amendment. As indicated in that <br />table, there is sufficient capacity in all of the segments to <br />accommodate the most intense use allowed by the proposed amendment. <br />51 <br />BOOK <br />
