collected on all arterial roadways that are impacted by 40 or more daily trips in order to complete <br />the concurrency analysis. <br />D. The TIA shall include each of the following analysis periods for the PM (and other) peak hours: <br />1. Existing traffic volume conditions and levels of service. <br />2. Future background volume conditions reflecting the year of opening for the development <br />and including traffic from pipeline projects. <br />3. Future traffic volume conditions for the year of opening and including traffic from pipeline <br />projects, plus the proposed project. All driveways and intersections that provide access to <br />the proposed development shall be evaluated. <br />4. Future traffic volume conditions with the proposed project and including traffic from <br />pipeline projects, with any proposed mitigation. The TIA shall include a description for <br />any proposed mitigation measures. <br />Approved phased developments shall be evaluated for the entire project and for the <br />individual phase applied for in the development permit. The TIA shall specifically identify <br />the amount, extent and timing of any required traffic mitigation and under which phase <br />mitigation will be completed. <br />E. The TIA shall include the following: <br />1. Evaluation of safety and circulation including collection of five (5) years of WSDOT crash <br />data at all study intersections. <br />2. Assessment of sight distance and sight lines at proposed access points/driveways. <br />3. Identification of geometric deficiencies or hazards. <br />4. Review of on-site roadways, intersections and driveways for adequate circulation and use <br />of design vehicle turning templates. <br />F. The County reserves the right to require an applicant to provide additional data and/or analysis <br />as part of a particular transportation impact analysis, where the County Engineer or designee <br />determines that additional information or analysis is necessary to implement the standards and <br />requirements contained in this section. <br />G. Changes to either the size or type of the land uses for the proposed development will require a <br />revised TIA study or an addendum. <br />H. The County may undertake an independent transportation impact analysis to confirm or revise <br />the results of the applicant's transportation impact analysis.
