Everett Safe Streets Traffic Impact Analysis 6. LEVEL OF SERVICE The analysis of the study intersections has been performed using the Synchro 9.1, Build 907 software. The existing level of service analysis has been performed using the existing intersection configuration, the existing peak-hour factors and the existing heavy-vehicle factors. The intersection of Berkshire Drive at the site access is currently a curve in the roadway with an access to the existing Reservoir #3 and the fire training facility. The existing curvature, both horizontally and vertically, limits the sight distance for turning vehicles. Additional control is recommended at the intersection to ensure safe operations of the intersection. It is recommended that northbound vehicles and vehicles exiting the site be stop-controlled. However, this sign configuration is not able to be analyzed in the Synchro 9.1 software and therefore the intersection has been analyzed as an all-way stop-controlled intersection. The level of service results for the study intersections for the 2016 existing conditions, 2021 baseline conditions and 2021 future with development conditions are summarized in Table 2. Table 2: Level of Service Summary 2016 Existing 2021 Baseline 2021 Future Intersection Conditions Conditions with Development Conditions LOS Delay LOS Delay LOS Delay 1. Berkshire Drive at A 7.0 sec A 7.1 sec A 7.1 sec Site Access 2. Berkshire Drive at A 7.1 sec A 7.2 sec A 7.2 sec 63`d Street SE The level of service analysis shows that the two study intersections currently operate at LOS A, the best level, and are anticipated to remain at LOS A with the development. The level of service calculations are included in the attachments. 7. TRAFFIC MITIGATION FEES The City of Everett has a traffic impact fee of $2,400 per PM peak-hour trip. Although the operational analysis was conducted with the conservatively high number of trips, the facility is only expected to generate 4 PM peak-hour trips.Therefore,the traffic mitigation fee for the Everett Safe Streets development would be $9,600. 8. CONCLUSIONS The Everett Safe Streets development is anticipated to generate 4 PM peak-hour trips and is not anticipated to change the existing operations of the study intersections. The traffic mitigation fees for the development are $9,600, based on the existing traffic mitigation fees. Gibson Traffic Consultants,Inc. October 2016 info@gibsontraffic.com 9 GTC#16-253
