Draft 7/27/2018 13 occurring earlier than the 2:30 to 3:30 Boeing PM Peak Hour determined in 1991. Once again,this cannot be confirmed until the first results have been tabulated for the permanent counting system. If the results of the permanent driveway counting system are consistent with Boeing's preliminary review(Attachment 1)they would be consistent with findings of a 2012 review of traffic volumes and capacities at 19 screenline locations in the SW Everett/Paine Field Subarea. This review found lower PM peak hour volumes than forecast in 1996 (see summary in the next section in this report). Accordingly, Boeing may be able to expand employment at its Paine Field facilities without exceeding the 12,315 trip baseline, provided that the Boeing PM Peak Hour does not shift later than 2:30 to 3:30 PM. If we assume that Boeing is currently at its 2001 approved maximum employment level of 35,000 and based on the preliminary Boeing data of 9,570 Boeing peak trips,the Boeing facilities could potentially add over 9,400 employees if the City monitoring system is consistent with the preliminary Boeing counts and within the SW Paine Field FEIS monitoring levels'. 1996 Planned Action Traffic Volumes and Capacities Review In 1996,the City of Everett completed a Planned Action for the SW Everett/Paine Field Subarea. The transportation analysis used in the environmental documents (EIS) for this Planned Action demonstrated that by 2030 the subarea, with certain transportation improvements, could accommodate increased traffic volumes associated with Subarea employment level growth to 83,000 employees. The transportation methodology was based on a subarea cordon with 19 screenline locations. Three alternative levels of employment growth were used to forecast daily trip volumes and impacts for 2015 and 2030. The daily volumes at screenline locations were converted to peak hour, peak direction volumes using standard traffic engineering assumptions. These peak hour,peak direction volumes were compared to the roadway capacities at each of the screenlines to compute volume to capacity ratios (V/C). The volumes and capacities for the 19 screenline locations were aggregated to compute an overall cordon PM peak hour V/C ratio. The approved EIS transportation analysis forecast that the overall cordon V/C ratio would be 1.0 in 2030 with the recommended high growth alternative of 83,000 employees and with the construction of a set of capacity improvements (paid for with a combination of mitigation fees, grants and city funds)to the road system. In 2012 a review of the current capacities and traffic volumes at the 19 screenline locations in the cordon was conducted. The analysis found that current daily volumes for If 33,500 employees generate 9,570 peak hour trips,the rate is about 0.29 trips per employee during the Boeing PM Peak Hour.Potentially Boeing could add another 2,745 peak hour trips before reaching the baseline of 12,315.At 0.29 trips per employee,it would take another 9,466 employees to reach the 12,315 total.
