§5-6 Traffic Impact Studies <br />Model Land Use Management Code <br />(o) Forecast Traffic Volumes With the Development. Forecast traffic volumes with the <br />development, on all arterial, collector and local roads within the study area, in the <br />year that the proposed development is planned to commence and in the horizon <br />year. <br />(p) Forecast Performance With the Development. Forecast performance, including <br />Levels of Service (LOS) and Volume/Capacity (V/C) ratios of the transportation <br />system with the development in the year that each phase is planned to be complete <br />and in the horizon year. <br />(q) Sight Distance. A safety analysis of the site accesses and an assessment whether <br />adequate sight distances are provided at driveways and streets abutting the <br />development. <br />(r) Operational Characteristics. Analysis of prevailing operating speeds, if significantly <br />different than speed limits, right and left turn lane warrants, queue lengths, <br />acceleration and deceleration lanes including lengths and tapers, throat lengths, <br />channelization, and other characteristics of the site accesses, which exist and may <br />be needed, as appropriate. The traffic impact study shall address whether driveways <br />and intersections are located and spaced safely and designed to accommodate <br />expected traffic volumes and maneuvers. The operational characteristics analysis <br />shall also evaluate the turning and traveling characteristics of the vehicles that will be <br />using the proposed development and the adequacy of the geometrics of the existing <br />and proposed roadway (public and/or private) configurations to accommodate these <br />characteristics. <br />(s) On-site Circulation. The traffic impact study shall address whether on-site vehicular <br />and pedestrian circulation and parking layouts are safe and efficient. <br />(t) Significant Impacts. Analysis as appropriate of any potential adverse or controversial <br />effects of the proposed development on the transportation system in the area. <br />Examples of possible effects include, but are not limited to, infiltration of non- <br />residential traffic into residential neighborhoods, traffic noise, creation of potential for <br />traffic violations, conflicting turning movements with other driveways, any new <br />pedestrian or bicycle transportation needs arising from the development, etc. <br />(u) Mitigation Measures and Costs. Listing of all intersections and road segments that <br />are forecasted to be Level of Service "E" and "F" in the horizon year, or if phased, in <br />the years that each phase is planned to be complete, and an identification and <br />description of specific mitigation measures including signal, turn lane, or other <br />warrant analyses as appropriate and necessary to bring these intersections and road <br />segments into compliance with a Level of Service "D" or other county [city] -adopted <br />Level of Service for said road segment or intersection. <br />If roadway improvements are needed, the study shall show a drawing at an engineering scale of <br />one inch equals twenty feet (1" = 20') for all recommended lane configurations. <br />If signalization is warranted by the traffic signal warrants outlined in the Manual on Uniform <br />Traffic Control Devices (MUTCD), a warrant analysis shall also be conducted as a part of the <br />traffic impact study. If a traffic signal is warranted, the warrant package in the study shall show <br />a drawing at an engineering scale of one inch equals twenty feet (1" = 20') detailing the signal <br />design and phasing plans. <br />The estimated cost associated with implementing all such mitigation measures shall be provided <br />in the traffic impact study. The traffic impact study may take into account any city/county/state <br />7 <br />P160 <br />
