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 (July 2005, prepared by Olympic Engineering.)
• Wetlands Inventory (July 2005, prepared by the Coot Company)
• Preliminary Storm Drainage Report (July 2005, prepared by Olympic Engineering.)
• Transportation Impact Study (July 2005, prepared by Transportation Engineering Northwest)
2. The City of Yelm has adopted a concurrency management system as required by the Growth
Management Act. Chapter 15.40 Yelm Municipal Code (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 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 South.
4. 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.
5. 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.
6. The Shoreline Management Act provides policies and regulations for development along Shorelines of
the State.
7. The Shoreline Master Program for the Thurston Region provides polices and regulations for
development along Yelm Creek.
8. 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
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. Credit should be given for the existing dwelling.
Prior to final subdivision approval, the developer shall complete the following transportation
improvements:
a. The west half of Crystal Springs 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 south.
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 open space, to include a
minimum of a 50 foot buffer from the creek and associated wetlands. This area shall be signed to
protect the shoreline environment, and shall provide public access to the Shoreline.
The developer shall enter into an agreement with Yelm Community Schools to mitigate project
impacts to the School District.

INTRODUCTION
This report documents the wetland/stream conditions within an X5.60 acre piece of
property within the City of Yelm. The property is currently abandoned "hobby farm"
land with a single rental home. Yelm Creek occurs along the western boundary of the
property within a defined landscape trough. This system has both stream (Type 3) and
wetland (Category III) characteristics within this property, and could be regulated as
either condition. The boundary flagged represents both the OHWM for a stream as well
as the edge of the technical wetland condition. All other areas within this property
outside of the Yelm Creek channel are well-drained uplands
METHODS
Site Inspection
Field review was performed on 19 July 2004. All areas of the property were inspected for
wetland and stream conditions.
Stream OHWM
Field flagging along Yelm Creek identified the Ordinary High Water Mark for the stream.
However, this edge could also be designated as a wetland boundary for regulatory
purposes (see Results).
Wetland Determination
Wetland determination followed a Routine Methodology based upon the Washington
State Wetland Identification and Delineation Manual (1997) requiring positive indicators
for wetland soil, hydrology, and plants.
Wetland Classification
Wetland characteristics are described within this report according to the Fish and Wildlife
Service Cowardin Classification System (1989).
Wetland Category Rating
The Washington State Wetlands Rating System for Western Washington (1993) was used
to establish Category Ratings for the wetlands.
Confirmation
Wetland status depicted in this report has not been confirmed by a government official,
and therefore has no legal status. Agencies with jurisdictional authority over wetlands at
the local, state and federal level need to be consulted for their signed agreement to our
findings before there is any guarantee of no change. Our estimation for the accuracy of
the unconfirmed wetland boundaries portrayed within this report is >95%.

RESULTS
Abandoned Hobby Farm
This property currently has asingle-family home occupied by renters. No active use of
the land beyond the home site yard occurs. Old fencing would indicate that some type of
livestock grazing occurred in the past, probably semi-rural "hobby farming" with
chickens, goats and a cow or two.
Well Drained Spanaway Soils
The entire landscape is underlain with well drained Spanaway soils. These soils are
naturally dark (1 chroma), but seldom sustain hydrology sufficient to qualify for technical
wetland conditions. However, low parts of the landscape, especially those next to
drainages, can experience high groundwater conditions during wet winters.
Yelm Creek System
The Yelm Creek channel represents the western boundary of this property. This system is
an Intermittent, Type 1 stream with seasonal salmonid use (Coho and Chum). All on-
property portions of the stream were dry at the time of field inspection, but property
immediately to the north had areas of both standing and flowing water. A detailed
description the Yelm Creek habitat within this property is provided in Appendix I.
TRPC Wetlands Mapping
TRPC wetland maps depict significant, adjacent, Palustrine habitats along both sides of
the Yelm Creek channel within this property. Careful field review found no clearly
positive wetland conditions beyond the stream channel. Some areas with low benches
adjacent to the stream channel and covered with solid reed canarygrass (Phalaris
arundinacea) occur, but soil inspection found no hydric characteristics that would
indicate sufficient saturation to qualify for wetland hydrology. These benches likely
sustain temporary saturation, if not shallow flooding, during wet periods in winter, but the
hydrology does not persist significantly beyond the duration of an associated precipitation
event.
Wetland or Stream?
The Yelm Creek channel is an unusual system in that significant portions of it normally
go dry for 2-3 months in summer and early fall because of the underlying well-drained
soils (Nisqually and Spanaway). Because of this unusual hydrology, many portions of the
stream channel grow hydrophytic vegetation once the surface flows have subsided.
Indeed, within this property, the actual "bed and bank" of the stream is sometimes hard to
locate within the dense growth of mostly reed canarygrass that occurs both within and
adjacent to the channel. Because streams are normally defined as "unvegetated scour
channels", the flagged OHWM of the stream could also be interpreted as the edge of a
technical wetland condition. For regulatory purposes of establishing buffers, it would be
appropriate to call this system either a wetland or a stream.

WIDTH
Channel width is variable between 4 and 6 feet.
LANDSCAPE POSITION: LANDSCAPE POSITION: Nisqually River Watershed
Yelm Creek is an approximately 9-mile long system set within fairly level glacial
outwash plain landscape. On-property portions are located approximately 1.5 miles
upstream from the confluence with the Nisqually River, and occur within a shallow but
well-defined landscape trough 10 to 20 feet lower than the surrounding landscape.
CLASSIFICATION
On-property portions of the Yelm Creek channel support dense emergent habitat
dominated by reed canarygrass. Surface water conditions vary dramatically from wet to
dry periods, with heavy sustained flows of many cubic feet per second during winter,
giving way to a dry streambed by early to mid-summer.

BOUNDARY DELINEATION
The OHWM flagged for this system is surprisingly indistinct within the limits of this
property. Dense reed canarygrass growth occurs within and adjacent to the channel, often
"hiding" it within the dense vegetation. In addition, the scour channel is poorly defined
within this very low gradient part of the stream. Flagging was "averaged" across wide
lengths, and was generous enough to include all portions where normal high water flows
would occur.
APPENDIX
FUNCTION ASSESSMENT
The following is a list of commonly recognized wetland functions, with an estimated
relative value rating for this wetland and a brief conceptual statement regarding the
primary factor affecting this rating. A summary table is also provided for quick reference.
HIGH MODERATE LOW NOT
APPLICABLE
3 0 5 0
Groundwater Recharge HIGH Well-drained underlying Spanaway
soils with significant, seasonal flows
Plant/Animal Habitat Value HIGH Seasonal salmonid use
Surface Water Runoff Route HIGH Locally prominent salmon-bearing
stream
Biofiltration LOW Surface water is generally fast
flowing when present
Flood Attenuation LOW Little to no adjacent overbank flood
zone.
Sediment Capture LOW High winter flows should wash away
most captured sediments
Stormwater Detention LOW Lacks significant depressional
structure; unrestricted outlet
Surface Water Supply LOW System supports only seasonal
outfall to Nisqually River
CATEGORY RATING: III (18 pts)
If rating as a wetland, the system qualifies for a high point Category III rating. Lack of
more than a single emergent class and poor habitat features prevented a higher Category
II rating.
STREAM TYPE: 1
If rating as a stream, the system qualifies for a Type 1 rating because it is listed as a
shoreline of the state.
