on those streets and their intersections which would require improvement measures such as approach widening and signalization. The improvement measures identified to mitigate the project 's traffic impacts are summarized in Table VI, along with the V/C ratios and levels of service which would result at the key intersections . Measures to Mitigate Cumulative Imoacts The cumulative (buildout) traffic volumes on study area streets will necessitate further improvement maintain acceptable measures to peak-hour traffic conditions. Improvements at ten ' of the sixteen key intersections will be warranted. The other six intersections either have Projected traffic conditions within the acceptable range, or have unacceptable projected conditions which can be tolerated until significant increases in minor street approach traffic occur. The recommended improvement measures are described below along with an indication of the project 's percentage contribution to the need for these improvements (based on the percentage its traffic represents of the total traffic entering the intersection at buildout levels ) . Figure VII summarizes the recommended mitigation improvement measures and the resulting peak-hour V/C ratios and levels of service at the buildout traffic volume levels . It should be recognized that, when the recommendations below call for addition of a lane to a given approach, there will also need to be widening of the leg on which traffic in this added lane exits the intersection. Ordinarily this widening need only be done for the minimum length necessary to safely merge traffic back into the original number of lanes. Charter Wav & Fresno Avenue - Widen the Fresno approaches by two lanes each, to provide two through lanes and a left-turn lane. Add one through lane to the eastbound Charter approach and widen the westbound Charter approach by two lanes , to provide two through lanes and two left-turn lanes . Add a fourth signal phase (to the traffic signal recommended as mitigation for existing-plus-project traffic impacts ) to provide protected left-turn movements on the Fresno approaches . (Project 's share is 27 percent. ) Charter Way 6 Argonaut Street - Add a through lane to each of the Charter approaches and install a three-phase traffic signal . (Project 's share is 18 percent. ) Joseph R Holland 7 LJr[ Consulting Trollle Engineer
