for afternoon peak hours during the peak season. Existing peak hours will be identified from traffic counts between 7:00 and 9:00 a.m., 11:30 a.m. and 1:30 p.m., and 4:00 and 6:00 p.m., using 15-minute intervals. Counts not taken during the peak season shall be factored, based on county traffic counts in the project area, to represent peak season conditions. Level of service calculations shall be based on the Operational Analysis methodology described in the latest edition of the Highway Capacity Manual. - Future levels of service shall be calculated for the buildout date of the proposed project, as well as for any intermediate development phases. Conditions with and without the proposed development shall be evaluated and documented. Conditions with the development shall be based on a combined traffic volume of the projected peak hour/peak season traffic generated by the site and the projected peak hour/peak season background traffic. The background traffic shall be calculated based on one of the following methods: a) Increase the existing peak season traffic to the buildout date based on historical growth trends over a minimum of 5 years and a maximum of 10 years. Traffic generated by committed developments, which would impact the study area, shall also be included subject to appeal to reviewing agencies. b) Increase the existing peak season traffic to the buildout date based on an interpolation using traffic volumes projected by the county. The county reserves the right to require method "a" to be used if it feels traffic projections may be inaccurate due to recent changes in land use or roadway improvements. - Roadway improvements which are committed and scheduled to be complete at or before the project buildout, or development phase date, may be included when calculating future levels of service. - Roadway improvements, which are necessary to maintain projected peak hour-peak season peak direction conditions at a level of service consistent with Policy 1.1, shall be identified. Policy 1.7: By 2023, the county shall consider imposing part or all of the ELMS one to five cent local option gas tax. New Policy: By 2030, the County will study and consider a mobility planning approach in lieu of transportation concurrency. Policy 1.12: The cCounty hereby adopts the 20405 Cost Feasible Plan projects list (Table 4.9.3) and, in so doing, acknowledges the MPO Long Range Transportation Plan as the means of maintaining level of service and mobility in the county.
