Findings of Fact
1. This Mitigated Determination of Non Significance is based on the project as proposed
and the impacts and potential mitigation measures reflected in the following
environmental documents:
• Environmental Checklist (May 2006, prepared by Skillings Connolly, Inc.)
• Hydraulic Report (May 2006, prepared by Skillings Connolly, Inc.)
• Traffic Impact Analysis (May 2006, prepared by Skillings Connolly, Inc.)
• Revised Traffic Impact Analysis (July 2006, prepared by Skillings Connolly, Inc.)
2. The City of Yelm has adopted a concurrency management system as required by the
Growth Management Act. Chapter 15.40 YMC (concurrency Management) is designed
to ensure that the improvements required to support development are available at the
time of development. A concurrency determination may be issued for a proposal as it
relates to transportation issues when: the development provides on-site frontage
improvements; the project makes off-site improvements as necessary to provide for the
safe movement of traffic; and the project makes a contribution to projects identified the
six year transportation improvement program in the form of a Transportation Facilities
Charge.
3. The City of Yelm and the Washington State Department of Transportation ("WSDOT")
have established a minimum intersection level of service ("LOS") standard of "D" for all
intersections in the City's commercial zones, with the exception of the intersection of
Yelm Avenue and First Street NW where the standard is LOS "F".
4. All intersections in the City are currently operating in compliance with the adopted LOS
standard.
5. The traffic impact analysis (TIA) submitted as part of the application indicates that the
project will generate an average of 1,130 vehicle trips per day, with a PM peak of 119
vehicles per hour. The TIA indicates that, with average growth, the proposal will impact
traffc movements at various intersections, including:
a significant increase in wait times at Yelm Avenue West and Mt. View
Road, Yelm Avenue West and Killion Road, Yelm Avenue West and
Longmire Street, and Yelm Avenue West and Cullens Road.
6. Section 14.04.055 YMC indicates that the principal guide in measuring environmental
impact is consistency with the land use designations of the comprehensive plan and the
development regulations designed to implement the plan.
7. Adding turn lanes, and widening substandard streets through the City transportation
system decreases the impact of additional traffic, both regional and local, on Yelm
Avenue (SR 507 and SR 510) and the intersections along Yelm Avenue. Adding turn
lanes at the highly impacted intersections will help mitigate impacts.
6. Mountain View Road is classified as a Neighborhood Collector street, but not currently
improved to collector standards. A neighborhood collector street is designed to
accommodate between 500 - 6000 average daily trips (ADT). Mountain View presently
accommodates approximately 315 ADT which the proposed subdivision would be
expected to increase by 565 ADT, an increase of 280 %. The present trips on Mountain
View Road do not exceed those far a neighborhood collector.
9. The City of Yelm is in the process of forming a Local Improvement District (LID) for the
realignment of Killion Road, and installation of a traffic signal, as well as reconstruction
of SR 510 (Yelm Avenue W) from Cullens Road to Burnett Road. The completion of
these improvements is required to mitigate the traffic impacts of the proposed
development.
10. Chapter 14.12 YMC requires the dedication of open space for all residential
development. Section 14.12.050 YMC lists four (4) attributes for qualification of open
space.
11. The Yelm School District has adopted a school mitigation requirement based on the
demand that new residential units create for additional school services and facilities.
Additional demands on the school system will be mitigated through the requirement that
the developer enter into a mitigation agreement with the District.
Mitigation Measures
1. Prior to final subdivision approval, the developer shall complete the following
transportation improvements:
a. The east half of Mt. View Road along the property frontage shall be improved to City
Standards for a Neighborhood Collector.
b. The intersection of Mt. View Road and SR 510 (Yelm Avenue W) shall be realigned,
and a left turn lane installed. Mt. View Road shall be improved to City Standards for
a Neighborhood Collector, from curb to curb, from the intersection of SR 510 to the
north property line.
c. Final approval of this plat is conditioned on the successful completion of all
improvements that are designed as part of the Killion Road LID, Phases I & II.
d. All interior streets shall be improved to City Standards for a Local Access
Residential.
2. Temporary erosion control systems shall be utilized to minimize offsite impacts from
erosion. The plans shall be approved by the City of Yelm.
3. The developer shall enter into an agreement with Yelm Community Schools to mitigate
project impacts to the School District.
