PROJECT TRAFFIC CHARACTERISTICS Ii ! U The two proJect-related characteristIcs havmg the most effect on area traffic condItIOns are peak hour traffic generatIOn and dIrectIOnal dIstributIOn of these volumes on the area roadway network. n U n Traffic Generation VehIcle traffic estImates are determmed through a process known as Trip GeneratIOn. Rates are apphed to the proposed land-use to estImate vehIcle tripS generated by a partIcular development durmg a specIfic tIme mterval. A vehIcular trip IS defined as a "smgle or one-dIrectIOnal vehIcle movement wIth eIther the OrIgm or destmatIOn (exItmg or entermg) mSIde the study sIte" The acknowledged source of trip generatIOn rates IS the Trip GeneratIOn Report prepared by the InstItute of TransportatIOn Engmeers (ITE) ITE has compIled surveys and estabhshed trip rates m studIes of convemence markets, sports bars and retaIl shops The trip rates used for thIS study are shown below m Table 1 l.J Ii U n u n n Ta.ble 1 Estimated Project Trip Ra.tes per 1,OOOsqtiare feet (sf) Evening Land-Use Size Land-Use Peak Inbound Outbound (in sf) Code Hour Trip % % Rate ConvenIence 2,500 853 73 05 48 52 Market w/fuel pumps Sports Bar 4,000 835 15 49 68 32 Strip RetaIl 15,000 814 493 57 43 , LJ , i U n u n LJ n U n U Applymg the precedmg trip rates to thIS project YIelds the total trip productIOn shown below on Table 2 The traffic volumes shown reflect a 10% reductIOn to account for mIxed-use mteractIOn between busmesses on-sIte '1 LJ n J Table 2 TotaIPr()jectTripGel1er~tion P.M..

Construct frontage Improvements along Creek Street and Yelm Avenue East. These Improvements would mclude the constructIOn of curb, gutter and sIdewalks, street lIghtmg and roadway wIdemng The actual extent of the Improvements wIll be determmed by the CIty of Yelm Development RevIew n J . Contnbute a proportIOnate share towards the planned Improvements at the "FIVe Corners" mtersectIOn. ThIs contributIOn wIll be based on the total new-to-network proJect traffic entermg the mtersectIOn durmg the peak hour At proJect completIOn m 1997, the Creek Street Commercwl Plat IS expected to add 121 pm. peak hour tnps to the "FIve Corners" mtersectIOn. The CIty of Yelm has Implemented a mItIgatIOn fee of $300 per new tnp ThIs mdIcates a developer contnbutIOn of $36,300 towards the proposed Improvement proJect. n I U Il U u . Construct Yelm Avenue East sIte dnvewav to prohIbIt left-turn mgress and egress A raIsed traffic Island wIth appropnate stnpmg and sIgmng should be mstalled at the dnveway entrance to lImIt all movements to nght-m, nght-out only ThIs type of access control wIll Improve safety and traffic operatIOns on Yelm Avenue East. n n LJ Il U ill LJ n, LJ '1 U n U n I U 11 LJ n I LJ S Chamberlalll & ASSOCIates, Inc.

CONCLUSIONS 'l L.J [I u The Creek Place project wIll mcrease traffic on the area roadways ThIs study has analyzed the hIghest traffic potentIal of the project at ItS completIOn m 1997 Results of the analysIs mdIcate that the study mtersectIOns wIll remam at acceptable levels of serVIce through project completIOn, wIth the exceptIOn of the "FIVe Corners" mtersectIOn. ThIs mtersectIOn has already been IdentIfied for Improvements and funds are bemg collected to Implement an Improvement program With the antIcIpated Improvements m place, the mtersectIOn wIll operate at an acceptable LOS through project completIOn m 1997 The project developer wIll contrIbute a proportIOnate share of the project expense, as IdentIfied m the mItIgatIOn sectIOn of thIS report. 11 U n u 'l u n u 'l LJ 'l u Il u n LJ Il u 'l Ll 11 J 'I I L.J 11 J 11 L.J il S Chamberlam & Associates, Inc.
