Mitigated Determination of Non-Significance
SUB-05-0345-YL
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 (January 9, 2006, Skillings Connolly, Inc.)
/ Final Hydraulic Report (January 2006, Skillings Connolly, Inc.)
/ Traffic Impact Analysis (January 9, 2006, Skillings Connolly, Inc.)
2. The environmental documents indicate that the property is composed of soils and
substrates that are suitable for building and for stormwater infiltration. There is no
indication that there are any potential significant impacts to the earth (geology,
topography, soils).
3. There is no indication in any of the environmental documents that there will be any
potential long-term significant impacts to air quality from the proposed development.
4. The City of Yelm is identified as a Critical Aquifer Recharge Area, a designated
environmentally sensitive area. Potential Impacts to groundwater quality and
quantity will be mitigated through measures that meet or exceed the standards in the
1992 DOE stormwater manual as adopted by the City of Yelm.
The City has adopted the 1992 Department of Ecology Drainage Design Manual,
which requires that stormwater generated from a development be treated for oils,
sediments, and heavy metals before infiltration.
5. The environmental documents do not identify a potential significant impact related to
the use of energy or natural resources.
8. The environmental checklist indicates noise generated from vehicles will be minimal.
9. 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.
10.The Growth Management Act at Section 36.70.070 (6)(b) RCW states that a finding
of concurrency can be issued when required improvements are in place at the time
of development or that a financial commitment is in place to complete the
improvements or strategies within six years.

11. Chapter 16.16 YMC requires that the layout of streets provide for continuation of
streets existing in adjoining subdivisions. The project provides a future street
connection to the north and west.
12. Section 16.16.050 (YMC) states that lots within a residential subdivision shall be
designed so that lots adjacent to arterial and collector streets are not allowed direct
access.
13.The traffic impact analysis (TIA) submitted as part of the application indicates that
the project will generate an average of 536 vehicle trips per day, with a PM peak of
56 vehicles per hour.
14. 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.
15.The checklist indicates that the proposal will not require addition fire or police
protection services.
16.Temporary construction impacts such as noise, light, water quality, and air quality,
are mitigated by requirements of the Zoning Code and Development Guidelines
relating to construction activities.
17.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 west half of Grove Road shall be improved to City Standards for a
Neighborhood Collector along the property frontage.
b. All interior streets shall be improved to City Standards for a Local Access
Residential.
c. The interior street shall provide a future street connection to the west and
north.
2. The developer shall enter into an agreement with Yelm Community Schools to
mitigate project impacts to the School District.
