Introduction
This report documents the transportation capacity impacts associated with the proposed Steel Lake
Crest Plat in Federal Way, Washington. The study focuses on evening peak hour traffic operations at
all intersections that are monitored for transportation concurrency and impacted by at least one (1)
new evening peak hour trip. All other transportation impacts are addressed by other applicable
development review processes. The analysis was conducted for 2009, the anticipated year of opening
of the development proposal for conditions with and without the project.
Purpose and Objectives
This study has been performed on behalf of the project applicant by the City of Federal Way, Public
Works Department, Traffic Services Division, and is consistent with the City of Federal Way
Transportation Concurrency Management Code as described in Federal Way City Code Chapter 19,
Article IV. The purpose of this code is to implement the transportation concurrency requirements of
the Growth Management Act, RCW 36A.70.070(6)(e), consistent with the City's Comprehensive
Plan and WAC 365-195-510 and 365-195-835. These requirements apply to all new developments
and expansions of existing developments and specify that the City may not permit development if
adequate capacity in the transportation system cannot be provided concurrent with the development.
Adequate capacity is deemed to be provided if the City's adopted Level of Service (LOS) standard is
met. The City's adopted LOS standard is contained in Comprehensive Plan TP16 and is summarized
in the table below:

Project Location and Description
The proposed development is located at 30642 28`h Avenue South, Federal Way, WA 98003. A
vicinity map is shown in Figure 1 below. The project would subdivide existing parcels into twenty-
eight lots with site improvements.

Background Conditions
Traffic forecasts for year 2009 conditions without the project are presented in this section,
representing the anticipated year of opening for the project. In addition, all projects shown on the
City's currently adopted Transportation Improvement Plan are assumed to be constructed consistent
with the Growth Management Act's definition of "concurrent with development".
The 2009 evening peak hour future volume for each study intersection was derived by applying a 2%
annual growth rate to the latest available volumes and adding trips reserved for approved
development projects. The background volumes are illustrated in Figure 2.

Site Generated Traffic
Evening peak hour trips generated by the proposed project were forecasted. The evening peak hour
trips were then distributed and assigned to the adjacent roadways and intersection within the study
area using the City's latest transportation model. No reduction in vehicle trips was made to account
for a potential shift away from the automobile. ITE trip rates are based on observed vehicle trip
patterns at each land use and thereby account for a basic amount of non -auto travel.
Trip Generation
The project would plat existing four lots into twenty-nine lots with site improvements. Currently,
there are three single-family residential units on the existing lots and full credit for these existing
residential units would be provided and is documented in Table 2.
The proposed development consists of twenty-eight new Single family residential lots. Trips
generated by the project were forecasted using trip generation rates found in the 7th Edition of Trip
Generation (ITE, 2003). ITE Land Use Code 210 was used to calculate the trip generation.
Procedures outlined in ITE's Trip Generation Handbook were used to determine when to use rates or
regression equations and calculating weighted averages between different independent variables.
These calculations are shown in Appendix A. As the concurrency application indicated that the
project includes twenty-nine units, the traffic model assumed that number of units. However, we
understand that the number of units were reduced to twenty-eight and therefore a proportionate credit
has been provided for the lot that was reduced from the original count. The project is expected to
generate a net total of 29 new evening peak hour trips. Table 2 below summarizes the trip generation
for the proposed development.

Trip Distribution and Assignment
The evening peak hour trips generated by the proposed project were distributed and assigned to the
roadway system as shown in Figure 3. The distribution is based on the City's travel demand model,
taking into account surrounding land uses and existing traffic patterns.

Pro-rata Share Traffic Mitigation
The City requires all new development projects impacting projects listed in the City's currently
adopted Transportation Improvement Plan (TIP) to either construct the impacted projects or provide
pro-rata share contributions towards these projects. The pro-rata contribution for each TIP project is
calculated as the number of new peak hour trips generated by the development divided by the
estimated total peak hour traffic volume at the time that phase of the development is completed.
If a TIP project has been deemed to be fully funded by the Public Works Director, the pro-rata share
will be calculated based on the design engineer's current cost estimate subtracting funding from
federal and state grants. If frontage improvements are also provided on a TIP project, the cost of the
frontage improvements provided by the development would be subtracted from the cost of the TIP
project before calculating pro-rata share of mitigation for off -site improvements. If the
development's impacts on a TIP project vary within the TIP project, depending on the operational or
safety issue the TIP project is intended to resolve, pro-rata shares may be calculated separately for
each segment that is impacted differently by dividing the cost of the TIP project on a per -lineal -foot
basis.
Based on the estimated trip generation and distribution of the project traffic, the project would impact
9 TIP projects by one or more trips during the weekday evening peak hour. In order to mitigate the
impacts of the new trips generated by the project and meeting the LOS standards, the applicant shall:
1. Prior to the issuance of final plat approval, construct the TIP projects identified in Table 4; or
2. Prior to the issuance of final plat approval, voluntarily pay the project's pro-rata share
contribution in the amount of $39,790.00. Please note that a credit of $8,231.00 (17.14%) has
been applied for the existing units and for one unit that was reduced from the original count.
The pro-rata share calculations are shown in Appendix C.

No level of service (LOS) deficiencies were noted at any of the City of Federal Way study
intersections. Therefore, no supplemental offsite mitigation is necessary. However, King County's
Military Road S/S 320th Street intersection would experience 7 p.m. peak hour project trips and the
intersection would operate at LOS F under both baseline and project conditions. King County uses a
30 p.m. peak hour trip threshold to assess location -specific mitigation; therefore no mitigation is
required.
Summary and Conclusions
The proposed development would subdivide existing parcels into twenty-eight lots with site
improvements.
The proposed development is forecast to generate net new 29 new evening peak hour trips.
All City intersections impacted by one or more evening peak hour trips from the proposed
development would meet City of Federal Way LOS standards with programmed
improvements, thus the transportation system provides adequate capacity concurrent with the
development. However, King County's Military Road S/S 320th Street intersection would
experience 7 p.m. peak hour project trips and the intersection would operate at LOS F under
both baseline and project conditions. King County uses a 30 p.m. peak hour trip threshold to
assess location -specific mitigation; therefore no mitigation is required.
The proposed development will either construct all TIP projects impacting by one or more
trips or voluntarily contribute $39,790.00 in pro-rata share contributions.
