Summary of Model Development Attached are the land use assumptions, zone structure map and model validation results of the traffic model. The land use data was developed by Jones & Stokes as part of the Federal Way City Center Planned Action EIS. The analysis focused on expected growth levels from 2004 to 2009 and 2009 to 2014.

Introduction/Background The City of Federal Way prepared a Planned Action EIS for a portion of City Center. The EIS considered two action alternatives, each of which assumes total development as shown in Table 1, and one no action alternative, which assumes future growth as identified in the City’s Comprehensive Plan. Although the two action alternatives assume the same amount of total growth, the growth is distributed throughout the study area differently under each alternative. Table 1.

In order to allow an analysis of potential transportation impacts of the proposal, future anticipated development must be further allocated into Transportation Analysis Zones (TAZ). Block 1 is comprised of 7 TAZs, Block 2 is comprised of 8 TAZs and Block 3 is comprised of 1 TAZ. The blocks and corresponding TAZs are described below. Block 1 (TAZs: 1049,1050,1051,1055,1056,1057,1058)– Bounded on the west by Pacific Highway South, on the north by South 312th Street, on the south by South 316th Street, and on the east by 23rd Avenue South. Block 2 (TAZs: 1060, 1061, 1062, 1063, 1064, 1065, 1066, 1067)– Bounded on the west by Pacific Highway South, on the north by South 316th Street, on the south by South 320th Street, and on the east by 23rd Avenue South. Block 3 (TAZ: 1072)– Bounded on the west by Pacific Highway South, on the north by South 316th Street, on the south by South 324th Street, and on the east by 23rd Avenue South. The approach for the allocations of future land use to TAZs is described below. 21 Federal Way Planned Action EIS TAZ Allocation Methodology Revised June 2006 2. No Action Alternative The City of Federal Way has allocations of future land use to the TAZ level for the entire study area. These allocations are based on the existing Comprehensive Plan land use forecasts and were assumed for the No Action Alternative. 3. Action Alternatives Allocation of future development to the TAZ level for the action alternatives is based on the allocation ratios established in the No Action Alternative. For example, Block 1 contains seven TAZs. Under the No Action Alternative, multi-family development within this block is distributed among these TAZs at ratios ranging from zero to 35 percent. These ratios were applied to the proposed multi-family development in Block 1 for each of the action alternatives. The process of identifying the ratio of TAZ to total block development was followed for each of the land use categories and applied to the action alternatives. The City’s TAZ land use allocations are provided for multi-family, office, retail and other uses. The action alternatives for this Planned EIS propose multi-family, office, retail, lodging (hotel), civic, and parking uses. To allocate parking in the City Center, the ratio for "retail" uses was assumed. For the purposes of allocation of lodging and civic uses for the action alternatives, the ratio for “other” uses was assumed. 4. 2009 and 2014 Model Network Assumptions The 2009 and 2014 baseline forecasts assume a variety of roadway and intersection improvements that are expected to be completed between 2004 and 2009 and between 2009 and 2014. City staff identified projects for inclusion in the 2009 and 2014 EMME/2 forecasting model used in the analysis. Projects were determined after review of the City of Federal Way’s2005-2010 Transportation Improvement Program, the City’s Capital Improvement Program, scheduled State Interchange improvements, expected improvements to the Interstate 5 corridor, and other known projects identified by City staff. Discussions with the City staff also identified model network assumptions and methodologies to be used to reflect High Occupancy Vehicle (HOV) lanes, turn restrictions and U-turn locations in the forecasting model. These network assumptions were held constant in the analysis the three alternative land use scenarios.
