LEEM SRETN ASSSTIATE 2 P Transportation Engineering NorthWest, LLc Memorandum DATE: TO: August 26,2008 Garth Mann / E,ltn Mcleod Statesman Group of Companies RE: FROM: Michael Read, P.E.c,Transportation Pleasant Harbor EIS Transportation Impact Study -Jeffersoo County, !7A Addendum Supplement to 77/27 /07 FEIS This memorandum serves as an addendum supplement to the Pleasant Harbor EIS Transportation Inpact Stud1, dated November 27 ,2007 , and discusses changes to vehicular site access assumptions, project trip generation, and the resultant changes in potential iuafftc impacts. This memorandum documents the following updates from the original transportation impact study: Point Road. Project Description As the project has progressed, and to respond to County requirements oudined in the FEIS, the applicant proposes to purchase t'wo shutde buses to transport groups tof from the site and SeaTac Airport for conferences and other events. The shutde buses would also be used for group excursions withinJefferson County and the Puget Sound area. Resort residents would also have the option of daily renting resort-provided electrical carts to ffavel between the Black Point Properties and the Maritime Village and other internal trips. The electrical carts would be able to circulate within the properties off of SR 101 by utilizing the private frontage road paralleling SR 101 between Black Point Road and the Maritime Village. A designated crossing point along Black Point Road would be constructed to provide for safe crossing for both pedestrians and electric carts. Vehicular site access would be consolidated for the Maritime Village and Black Point Property at SR 101 and Black Point Road under the Statesman Alternative. The existing northern driveway on SR 101 from the Maritime Village would consist of a24-foottvrde, two-lane section to accommodate exiting vehicular ftafftc, however, entering trafftc would be restricted to emergency vehicles only. AII other existing access connections onto SR 101 would be closed and removed. Figute 1 provides an exhibit of the overall circulation plan. Appendix A provides exhibits of proposed site access configurations at key locations. www.tenw.com PO Box 65254 o Seaule, WA 981 55 Office/Fax (206) 361-7333 o Toll Free (888) 220-7333 Pleasant Harbor EIS - Jefferson County, WA Addendum Supplement to 11/27 /O7 FEIS August 26, 2008 Page 2 Maritime Village Drivewav on SR l0 I Exlt-OnD All Vehlcles ,a tcEnter- Emergency Vehlcles Only 0 ,f .d .f 'l t- Marltlme Vlllage Drlveway on Black Polnt Road TweWay Enter/Exlt Electrlc Vehlcles PorntRd ffi l, Golf Coure Secondary Acces Black Emergency and Maintenancdl",lll Service Vehlcles tI ,.tI?t., J E tl 0 (Not to S€le) h P, Transportation' Engineering NorthWest, LLC Figure I Proiect Site Plan Pleasant Harbor SEIS Jefferson County, WA Transportation Engineering Northwest, LLC PO Box 65254 .

Onto Black Point Road, a conunon 24-foot wide frontage road system would be located approximately 300 feet east of SR 101. The existing traffic and access driveway onto Black Point Road from the State Boat Launch should be realigned to intersect with this corffnon frontage road to the Maritime Village north of Black Point Road. Currently this Washington State Fish & Wildlife WSFIQ driveway does not meet geometdc standards, nor does it provide adequate sight distance. The common 24-foot wide frontage road would serve the proposed residential water touch lots as part of the Maritime Village and terminate at the end existing residence. A single lane, 16-foot wide roadway above the common frontage road would provide directional vehicular access to the Maritime Village. This roadway would be a multipurpose roadway and would be designed to serve one-way vehicle access, and two-way pedestrian and electric-cart cfuculation needs between the Maritime Village and Golf Course/Conference Center areas of the development. SR 101would serye all traffictof fromthe Golf Course/Conference Center. SR 101 that would be gated and used for emergency vehicles and stafff maintenance access only and align with the frontage road into the Maritime Village. This proposed four-way intersection with Black Point Road would also provide a crossing treatment to serve both pedestrian and golf cart circulation vdthin the properties. Figute 2 provides an exhibit of this intersection and vicinity. No changes were made to the access assumptions under the No Action Alternative, Hybrid or Brinnon Subarea PIan alternatives. Trip Generation The land use assumptions for all alternatives would remain the same as those oudined in the DEIS, except the Statesman Altemative. Under the proposed revisions to trip reduction measures proposed under the Statesman Alternatives, a teduction in total project trips based upon external trips for the proposed t'wo shutde buses transporting people to/from the Seatde-Tacoma Airport and providing group excursion trips. It should be noted that internal trips via electrical electric carts between the Maritime Village and Black Point Property were identified to be accommodated in the 20 percent reduction of total internal trips identified in the original ransportation impact study. Thetefore, no trips were added or reduced for this assumption.

The airport shutde bus would most likely experience a maximum of 8 total daily trips on a peak day with a morning, mid-day, evening, and late evening round-trips. (Note that each round trip would count as two one-way daily trips). Thus, there would be 2 p.m. peak hour trips (1 entering uip and 1 exiting or two coaches arriving or departing from the airport). The proposed shutde buses would hold up to 40 passengers, and therefore, there would be a total of up to 320 passengers per day or 80 passengers during the p.m. peak hour. Accounting for average vehicle occupancies (AVO = 1.2 persons per vehicle), the resultant potential in trip reduction would be up to approximately 260 dany Q68 daily vehicle trips minus 8 total daily shutde bus trips) and 65 p,m. peak hour trips (67 passenger trips minus 2 totd, p.m. peak hour shutde bus uips). Net Project Trip Generation Table 1 summarizes net project trip generation for all Statesman Alternative. As shown, net project trip generation would be reduced to approximately 298 p.m. peak hour trips and approximately 3,840 trips. Table 1: Net T Generation Affected 1-upon 2 - Rounded to the nerest 10. in the Harbor 1i, Trip Distribution Overall trip distribution and assignment would remain the same as identiFred in the original ttansportation impact study. However, trip distribution and assignment at the critical site access intersection of SR 101 / BbckPoint Road and the other site access points onto SR 101 and Black Point Road were redistributed based upon site access changes identified in the Project Ducription section above. Traffic Volume lmpacts The reduction of approximately 260 vehicular ddly project uips would have litde change in the relative impact along vicinity roadways aralyzed in the original uansportation impact study under the Statesman Alternative. The reduction in project trips would reduce total traffirc volumes in 2077 by approximately 6 percent. Daily traffic volume forecasts are provided in Attachment B.

Site Access, Safety, and Circulation lssues This section updates the following: Site Driveway Operations, Left-Turn LaneWaruants and Right-Turn Lane W'arrants based upon the site access and trip generation changes previously identified above. Site Driveway Operations Under all Statesman Alternative, critical stop-controlled entering/exiting movements at project site driveways onto SR 101 and Black Point Road would operate at LOS B or better with litde ot no vehicular queuing. The critical site access intersection of SR 101 at Black Point Road would operate at LOS B or better with queues of 1 vehicle or less under the Statesman Alternative n 2077 . Intersection turning movement forecasts and detailed level of service summary worksheets for all site driveways intersections are provided in Attachments B and C. Left-Turn Lane Warrants Left-turn movements fepresent critical turning movements at unsignalized intersections, increasing the potential for intersection delay and safety issues. Based upon procedures and guidelines found in WSDOT's Design Manual, November 2007 (Frgure 970-72a Left-Turn Storage Guidelines Two Lane-Unsignalized), a southbound left-turn lane is warranted under the Statesman Alternative. Based upon WSDOT's Design Manual, November 2007 (Figure 910-13b Left-Turn Storage Length: Two Lane-Unsignalized), for a 50 mph posted speed limit on SR 101, the southbound left-turn lane should be a minimum of 100 feet.

Therefore, at the critical site access intersection of SR 101 at Black Point Road, the potential need for a northbound right-turn lane was anilyzed considering typical evening cofiunute periods. Based upoo procedures and guidelines found in WSDOT's Design Manual, November 2007 (Frgure 910-11 Right-Turn Lane Guidelines), a northbound right-turn taper/ pocket is warranted under the Statesman Alternative. Based upon WSDOT's Design Manual, November 2007 (Figure 910-16 RighrTurn Pocket and Taper), the northbound right-turn pocket should be a minimum of 60 feet with a 100-foot tapet.
