ATTACHMENT <br /> ADDITIONAL TRAFFIC IMPACT MITIGATION MEASURES <br /> Project Impact Mitigation <br /> The December 2000 San Joaquin County Traffic Study Guidelines were used to define <br /> conditions where a project significantly impacts area roadways and intersections, and the <br /> methodology required to calculate the fair share contribution of a development to the costs of <br /> improvements necessary to fully mitigate significant project impacts. This criteria is <br /> described below for Cumulative Plus Project Conditions: <br /> If the LOS for [Cumulative Plus Project Conditions] exceeds the County's <br /> LOS standards, then mitigation measures that would improve the LOS to an <br /> acceptable level must be identified. LOS must be expressed in terms of delay <br /> in seconds for intersections, and vehicles per hour for roadway segments3, in <br /> addition to the corresponding letter(A-F) designation. <br /> If the LOS for conditions at a given location is already at an unacceptable <br /> LOS, then the impacts must be assessed in terms of We ratio ' (for roadway <br /> segments) or 'delay' (for intersection approaches). If the We ratio'for a <br /> roadway segment, under `cumulative plus project'conditions, exceeds the v/c <br /> ratio for the same roadway segment under 'cumulative' conditions then <br /> mitigation measures that would return the `v/c' ratio to the cumulative' level <br /> must be identified. Similarly, if the 'delay' at a given intersection approach <br /> under 'cumulative plus project' conditions exceeds the 'delay'for the same <br /> intersection approach under 'cumulative'condition, then mitigation measures <br /> that would return the 'delay' to the 'existing' conditions, then mitigation <br /> measures that would return the 'delay' to the 'cumulative' level must be <br /> identified. <br /> 3 As discussed earlier, and as agreed to by San Joaquin County engineering staff, roadway analysis within this <br /> report describes roadway LOS in terms ofdaily traffic and LOSgrades as reported in the "1998 LOS <br /> Handbook", Florida DOT. <br /> ibid. <br /> Delta Church of the Nazarene July 3,1001 <br /> Traffic Impact Analysis 39 <br />
