The project will add 82 v.p.h. to the interchange.

Broadwav Avenue/S.R. 526 � At the S.R. 526/Broadway Avenue intersection, WSDOT is planning a major project which will include a grade separated interchange at the intersection and changes to the current interchange tivith I-5. The estimated cost of these improvements is $20,000,000. The project will add 29 v.p.h. to the intersection. Based upon 1995 p.m. peak hour volumes using the intersection (10,589 v.p.h.), � including traffic using the EB S.R. 526 to SB I-5 ramp, the developer s proportionate share of these improvements will be 0.27 percent or 554,000. � Site Access Concerns One driveway, the most southerly access to Evergreen Wey, may operate at LOS 'F' for the left turn movement in the p.m. peak. Because of the effect of the traffic signals on Evergreen Way, this LOS may be much worse than will actually be experienced since the � effects of signals and the dearee of platooning they cause is not considered in standard unsignalized intersection LOS analysis (see Appendix I, Hiqhwav Cavacitv Manual, Special Report 209, Transportation Research Board, 1985). Furthermore, an additional drivEway exists to the soutn which the left turning traffic could divert to should delays prove cnacceptable. At that driveway, the � LOS for the right turn movement will be 'A'. This movement could be utilized by diverted traffic bound to the south and to the west. '� s a � � !Bi Vehicle queueing at the Madison Street/Evergreen Way intersection does not appear to be a significant problem in relation to the operation of the driveways. The operation of the southern most driveway will be impacted to some degree for the left turn movement by the queueing of southbound through traffic on Evergreen Way. Assuming a 120 second cycle length, the queue might at times extend as much as 490 £eet north of the intersection. However, queues in the left turn lane and the two way, left turn lane at the driveway should extend no more than 80 feet. Since the driveway is located about 270 feet north of the STOP bar, there should be no operational difficulties since the left turning vehicle can enter the two way, left turn lane prior to merging into the through traffic stream. -23- ,/ Chrislopher 6rou�n C�s Assoeiales " Si9 Rainier Avenue N.. �uite A-201 '� Renlon. u�A 980i�-1380 ` _� (206) ii?-1185
