Findings of Fact
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 (April 2006, prepared by Baseline Engineering)
Preliminary Storm Drainage Report (April 2006, prepared by Baseline Engineering)
Traffic Impact Analysis (April 2006, prepared by Heath & Associates, 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. 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.
4. 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. The developer shall mitigate transportation impacts based on the new residential P.M.
peak hour trips generated by the project. The Transportation Facility Charge (TFC) shall
be based on 1.01 new peak hour trips per residential unit. The proponent will be
responsible for a TFC of $757.50 per dwelling unit which is payable at time of building
permit. Credit should be given for the recently destroyed single-family dwelling.
2. Prior to final subdivision approval, the developer shall complete the following
transportation improvements:
a. All interior streets shall be improved to City Standards for a Local Access Residential
b. The interior street shall connect to the residential subdivision to the east called Vista
Green. Final plat approval for this proposal shall be conditioned on the final plat
approval and street dedication of the Vista Green subdivision.
c. A cul-de-sac shall be constructed at the north end of the interior street, and signed
"future street connection'.
d. SR 510 (Yelm Ave W), at the intersection of Longmire Street, shall be improved to
provide a center turn lane with sufficient storage to serve the anticipated traffic
volumes generated by the project. This intersection improvement is a condition of a
different plat approval called Tahoma Terra. If the Tahoma Terra subdivision does
not complete the intersection improvement prior to final plat approval for this
subdivision, this plat approval will be conditioned to limit final plat approval to after
the Tahoma Terra improvements are complete.
3. Temporary erosion control systems to be approved by the City of Yelm.
4. The developer shall provide at least 5% of total acreage as qualified and usable open
space.
5. The developer shall enter into an agreement with Yelm Community Schools to mitigate
project impacts to the School District.
