Community Transit — Merrill Creek Facility Renovation — Transportation Analysis heffron transportation inc building employee trips), the rate is lower-0.102 trips per employee. This is expected since few of the MCOB employees make trips during the PM peak hours due to the function of the transit base. 2.3. Future Without -Project Conditions The proposed project and staff re -assignments are planned to be complete by 2025; however, the City of Everett typically requires traffic analyses to evaluate a horizon year that is no earlier than six years from the date of the completed project application.' Since project applications are expected to be submitted in 2021, year 2027 was selected as the horizon year. Forecast 2027 without -project traffic volume forecasts were developed in several steps. First, background through traffic on Hardeson Road was increased by 12% to reflect normalized (non - pandemic) conditions based on the historical count comparisons presented previously. Then, a background traffic growth rate was applied. Based on review of historical PM peak hour traffic counts performed by the City of Everett at the Hardeson Road / Merrill Creek Parkway intersection (in September 2011 and October 2018), the volumes on Hardeson Road grew by about 0.5% per year over seven years. Therefore, a 0.5% compound annual growth rate was applied to the normalized through volumes on Hardeson Road to reflect year 2027 without -project conditions. Finally, the estimated combined CT Merrill Creek site traffic presented in Table 2 was added to reflect future conditions without the project, but with site traffic returning to the baseline condition. The forecast 2027-without- project PM peak hour traffic volumes are shown on Figure 6. 2.4. Traffic Operations Traffic operations analyses were performed for the three study -area intersections. Traffic operations are evaluated using level of service (LOS) with six letter designations, "A" through "F." LOS A is the best and represents good traffic operations with little or no delay to motorists. LOS F is the worst and indicates poor traffic operations with long delays. More information about the level of service definitions and thresholds are provided in Attachment A. As outlined the City's Comprehensive Plan- Transportation Element,8 the LOS standards adopted by the City of Everett are LOS D in general, and LOS E/F, if approved by the City Engineer. Levels of service for the study area intersections were determined using procedures in the Highway Capacity Manual 0 Edition.9 All level of service calculations were performed using the Synchro 10.3 traffic operations analysis software using the HCM 6 reporting module for unsignalized intersections. Table 3 summarizes existing and forecast 2027 PM peak hour levels of service without the proposed project. As shown, the three intersections currently operate at LOS A overall and all movements operate at LOS C or better. With the assumed increases in background traffic, some increases in delay are expected, but all three locations are forecast to remain operating at LOS A overall with all movements at LOS C or better. The analyses indicate a slight decline in total overall average delay at the northern driveway intersection, which can occur when volumes increase on non -critical movements that have little or no delay, thus reducing the overall average delay.
