TRANSPORTATION CONCURRENCY
ANALYSIS
Lifeway Church
08-105510-00-CN
Prepared by
Sarady Long, Senior Transportation Planning Engineer
tN'FP d 01 Dc•r zzno I
Introduction
This analysis studies the transportation capacity impacts for the proposal to construct a 21,705
sq. ft. church located at the southwest corner of SW 3561h Street & V Avenue South, Federal
Way, Washington. The study focuses on evening peak hour traffic operations at all intersections
monitored for transportation concurrency 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 2011, 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 Revise Code
Chapter 19.90. 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 development and expansions of existing development and specify that the City may not
permit development if adequate capacity in the transportation system cannot be provided to the
development 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 the southwest corner of SW 356' Street and 1" Avenue
South intersection, Federal Way, Washington. The development proposal would construct a
21,705 sq. ft. church. A vicinity map is shown in Figure 1.

Background Conditions
Traffic forecasts for year 2011 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 the development".
The 2011 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 Figures 2 through 4.

Site Generated Traffic
Evening peak hour trips generated by the proposed project were forecast. The forecast
considered pass -by trips if applicable. 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. TTE 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
Trips generated by the project were forecast using trip generation rates found in the 8th Edition
of Trip Generation (TTE, 2003). Procedures outlined in TTE's Trip Generation Handbook were
used to determine when to use rates or regression equations. These calculations are shown in
Appendix A. The project is forecast to generate a total of 12 evening peak hour trips. Table 2
below summarizes the trip generation for the proposed development as calculated by the
applicant's Traffic Engineer and approved by the City.

the roadway system as shown in Figures 5. The distribution is based on the City's travel demand
model.

Traffic Analysis
The quality of traffic flow at the key study intersections is presented in this section of the report.
Based on the model assignment in Figure 5, intersections impacted by at least one or more
evening peak hour trips were analyzed for meeting concurrency LOS standards.
Table 3 shows a summary of the LOS analysis for the study intersections with v/c ratio at least
0.50 or above and LOS B to F. Where a performance measure does not apply to the entire
intersection, the table shows the measure for the worst movement of the intersection. Detailed
LOS calculations for Background Conditions and Horizon Year conditions with project trips are
available upon request from the Public Works Traffic Division. For study intersections requiring
pro-rata mitigation, the LOS Summary Worksheet is included in Appendix B.

Pro-rata Share Traffic Mitigation
The City requires all new development projects impacting projects listed in the City's current
adopted Transportation Improvement Plan (TIP) by one or more evening peak hour trips to
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.
14
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 projects listed on the current 2010-2015 TIP 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 recoding of final plat, the applicant shall pay the project's pro-rata share
contribution in the amount of $25,143.00 towards the 2010-2015 Transportation
Improvement Plan (TIP) projects. The pro-rata share calculations are shown in Appendix
C.
Summary and Conclusions
■ The proposed development consists of a 21,705 square foot church.
■ The proposed development is forecast to generate 12 new evening peak hour trips.
■ All intersections impacted by one or more evening peak hour trips from the
proposed development would meet the City of Federal Way LOS standards with
programmed improvements.
■ The proposed development will impacted all TIP projects by at least one or more
evening peak hour trips and thus shall contribute $25,143.00 in pro-rata share
contributions.
