This CONCURRENCY DETERMINATION is made this .25rd day of January 2007, by the City of Federal
Way (COFW), a political subdivision of the State of Washington (hereinafter called the "City"),
Whereas, the developer intends to develop the property described as Federal Way Townhomes
reviewed under City file CN Number (s)
and
07-100013-CN
(hereinafter called the "development");
Whereas, RCW 36.70A requires that the City adopt and enforce ordinances which prohibit development approval
if the development causes the level of service on a transportation facility to decline below the standards adopted in the
comprehensive plan, unless transportation improvements or strategies to accommodate the iOmpacts of the
development are made concurrent with the development; and
Whereas, the City adopted its comprehensive plan in November 1995 ; and
Whereas, Chapter 19 of the COFW Municipal Code was amended by the creation of Article IV on June 10, 2006
by Ordinance 06-525 effective January 1, 2007; and

Transportation Concurrency Analysis
1 /29/2007
Introduction
This analysis studies the transportation capacity impacts for the proposed development in 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 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 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 TP 16 and is summarized in the table below:

Project Location and Description rd
The proposed development is located at 2245 South 333 St. A vicinity map is shown in Figure
I below. Existing land uses on the site are 2 (two) townhomes. The proposed project would
consist of nine new (9) townhornes.

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 the 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 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. 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
An existing single family townhome currently occupy the site. Credit for the existing uses will
not be provided as the trips are not vested.
The proposed development consists of nine (9) new townhomes. Trips generated by the project
were forecast using trip generation rates found in the 7th Edition of Trip Generation (ITE, 2003).
Land Use Code 230, Residential Condominium/Townhouse 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. Equivalencies from the 5th edition of Trip Generation were used to
estimate independent variables not available at this planning level of development, such as
number of persons and vehicles. These calculations are shown in Appendix A. The project is
forecast to generate a total of five (5) evening peak hour trips. Table 2 below summarizes the
trips generation for the proposed development.

Trip Distribution and Assignment
The evening peak hour trips generated by the proposed project were distributed and assigned to

Traffic Analysis
The quality of traffic flow at the key study intersections is presented in this section of the report.
Table 3 shows a summary of the LOS analysis for the study intersections. 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 are shown in Appendix B for
Background Conditions and Horizon Year conditions with project trips.

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) to construct the impacted projects or at the
applicant's option voluntarily 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.
-10-
Based on the estimated trip generation and distribution of the project traffic, the project would
not impact any TIP projects by one or more trips during the weekday evening peak hour.
Therefore, no pro-rata mitigation towards TIP projects is necessary.
No level of service (LOS) deficiencies were noted outside of locations where programmed
improvements would be constructed. Therefore, no supplemental offsite mitigation is necessary.
Summary and Conclusions
■ The proposed development would replace an existing townhome land use with
nine new townhomes.
■ The proposed development is forecast to generate five (5) new evening peak hour
trips.
■ All -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.
■ The proposed development does not impact any TIP project by.one or more trips,
therefore no mitigation towards impacts TIP projects is necessary.
