The Transportation Element establishes a basis tor decision-making that is consistent with Washington's Growth Management Act, King County's Countywide Planning Policies, and the Puyet Sound Regional Council's (PSRC) Transportation zuk.u. The specific requirements of each of these plans are tultilled by the City of Tukwila o ranbporration Element Background ReportQcluding a revised Travel Demand Memorandum dated December 3u. _zo3.6.) of the Comprehensive Plan Update (hereafter reterred to in this element as the Background Report), and summarized Herein.

Physical barriers include the valley wall, the Green/Duwamish River, and highways that separate portions of the City trom each other, increasing emergency services response times and cost. Residents value quiet neiyhborhood streets that exist in an incomplete or disconnected street system. With relatively few "through" streets, many vehicles use the streets that do connect, burdeniny the adjacent properties and residents. The large volume of vehicles an thruoyh-streets also makes it more difficult to walk to destinations such as schools, libraries ur shuppiny. u Limited fundiny to satisty competing priorities. 58 — Increasing connectivity is very costly given the need to acyoire new rights-of-way, conductiny engineering studies and design, and constrocticn costs. — Criteria for yrnt fon'ainy are mG.t utten targeted to oRvvila'b Or5an Center or the Manufacturing/Industrial Center because these are the locations wSere signiticant employment and residential growth are planned and are supported By regional plans. — There are unmet needs in other areas of the City, includiny streets that do not meet City standard, and it is unlikely that the roads would Se improved Sy new development in these already developed areas. to, Reliance on regional agencies, such as the Port of Seattle, Metro and Sound Transit, to serve local needs. GOAES, POLICIES AND STRATEGIES The Transportation Element supports the City's Land Use Element. It demonstrates how the City will maintain and preserve the existiny network as well as address deticiencies, while demonstrating how planned growth will be accommodated over the next zo years per the Office of Financial IGlanayement (OFM) and PSRC torecasts. The household and job forecasts for Tukwila are for an additional :4)4,800 Households and 27,-67,5J5s by the year =+ _ 1, with most of that occurriny in tRe Soutlicenter, TuICwila International Boulevard and Tukwila South mixed-use commercial areas. To plan tor land use and transportation changes associated wit this yrowth, these Souseliolds and jobs are assigned to Traffic Analysis cones (TAZs) based on the availability of vacant and redevelopa5le lands (Maps 13-1 and 13-z).

Properly applied and monitored, COS standards fur the transpurtatiun networR ensure that mobility, vitality and quality of life forthe city is maintained.
