Wetland Report for Nisqually Estates
ThIS report descrIbes wetlands occurrIng on and adjacent to property known as
Nisqually Estates, DIVISIOn 1 & 2. The property IS co-owned by Mark Carpenter and
Paul Steadman. The wetland delIneatIOn and report was prepared by Doug Swanson
of Swan Resources The property was VIsIted on November 16 and November 29,
1994 Mr Carpenter requested a wetland delIneatIOn and report prIor to subdIVIdIng
the 25-acre SIte mto approxImately 120 lots
SETTING
The property IS one-half a mIle southwest of the center of the CIty of Yelm m the
NW 1/4 of the NE 1/4 of SectIon 25, TownshIp 17 N, Range 1 E, WM The property
IS roughly tnangular wIth the longest sIde frontIng on an abandoned raIlroad nght
of-way and SR 507, the Yelm-Ralmer Highway (ViCInIty map, Fig 1) Most of the
parcellS at elevatlOns rangmg from 340 to 360 feet. A small depreSSIon In the
northeast corner IS 20 feet lower and the east sIde of the property slopes down
toward a wetland complex that IS the headwaters of Thompson Creek (WRIA 11
0041), a three-mIle long tnbutary of the Nisqually RIver
SOILS
Four soIl map umts occur on the SIte Over 90 percent of the SIte IS mapped as
gravelly sandy loams of two dIfferent sOli senes. The northern two-thIrds of the
property IS mapped as Spanaway gravelly sandy loam, 0 to 3 percent slopes (map
umt 110) The south end of the property IS mapped as Everett very gravelly sandy
loam 0 to 3 percent slopes (map umt 32) The slopes of the depreSSIOn In the
northeast corner are mapped as Spanaway stony sandy loam 3 to 15 percent slopes
(map umt 113) A small area on the west edge of the property IS part of a larger area
mapped as dramed Mukllteo muck (map umt 70)(Pnngle 1990)
The Spanaway and Everett map umts are somewhat excessIvely dramed soIls
typIcally found m upland areas of glaCIal outwash and tIll The Mukllteo SOli IS a
very deep, very poorly dramed SOli found m depreSSIOns Dramage m the Mukllteo
umt has been altered by open dItches or subsurface drams to faCIlitate agncultural
use (Pnngle 1990) The MukIlteo muck IS lIsted as a hydnc (wetland) soil m Thurston
County
WETLANDS
Wetlands were delIneated USIng the Federal Method for IdentIfYIng and DelIneatIng
JUrISdIctIOnal Wetlands (FICWD 1989), as reqUIred by the Thurston County CntIcal
Areas Ordmance Wetland boundanes were marked USIng pInk and black stnpped
plastIc flaggIng placed at Intervals of 20 to 50 feet. Flagging IS numbered
consecutIvely, as IndIcated on the aenal photograph (Fig 2) and In the descnptIOns
below Wetlands were rated USIng the Department of Ecology's WashIngton State
Wetland RatIng System, Western WashIngton, second edItIOn, 1993

Two wetlands occur on the property There IS a small Category III wetland m the
depreSSIOn m the northeast comer and a larger Category II wetland along the west
edge of the property (ratmg forms are m Appendix A) The Category II wetland IS
part of the headwaters of Thompson Creek and IS mapped as a palustnne forested
wetland on the NatIOnal Wetland Inventory maps. A third small area m a depreSSIOn
m the south part of the property has predommantly wetland vegetatIOn, but lacks
hydnc SOlIs and wetland hydrology and IS therefor not a JunsdlctIOnal wetland.
Wetland No.1 - DepreSSIOn at the northeast corner of the property
This wetland IS m a small depreSSIOn about 100 feet Wide and 300 feet long About
40 percent of the wetland IS on the Nisqually Estates property With the remamder on
the golf course property to the north. ThiS area appears to have been part of a larger
wetland on the east Side of SR 507, known as McKenZie Lake ConstructIOn of the
railroad and SR 507 Isolated thiS small area from the larger wetland on the east Side
of the highway
The wetland boundary was delmeated and flagged startmg at the northeast comer of
the property (flag W 1-1) and contmumg clockWise to where It agam mtersects the
north property lme (flag W 1-8) The wetland/upland boundary on the east, south,
and west Sides of the wetland IS dlstmctly marked by an abrupt change m the plant
commumty and a sharp topographiC break.
Wetland classes With areas greater than 0 25 acre mclude palustnne emergent and
scrub-shrub, as claSSified usmg the U S Fish and WildlIfe Service system (Cowardm
et al 1979, ClaSSificatIOn of Wetlands and Deepwater Habitats of the Umted States)
ThiS wetland IS rated a Category III wetland based on ItS small Size, lack of effectIve
buffers, and hydrologic IsolatIOn. The wetland scored 17 pomts usmg the Slgmficant
Habitat Value sectIOn of the ratmg system (AppendiX A) WildlIfe value IS low for
small numbers of amphtblans, birds and small mammals Thurston County deSignates
thiS category as Class III wetlands for the purposes of the CntIcal Areas Ordmance
Wetland SOlls.--The soIls on the Side slopes of the depreSSIOn appear to be typical of
the Spanaway senes mapped for thIS locatIOn. SoIls in the bottom of the depreSSIOn
are finer textured and had low chromas and mottlIng mdlcatmg a shallow fluctuatmg
water table A SOlI profile hole, flagged and labeled as SP-l, was dug about 60 feet
southwest of the north property lme near the center of the portIOn of the wetland

Wetland No.2 - West edge of the property
ApprOXImately 5000 square feet of thIS 8 acre wetland IS on the Nisqually Estates
sIte The maJonty of thIS wetland IS on the adjacent property to the west. Wetland
boundary markers are present along the wetland boundary on the adjacent property
Three boundary markers (W 2-1 to W 2-3) were attached to the west property fence
and are labeled showmg an approxImate offset to the wetland edge on the adjacent

at W 2-7 and endIng at W 2-13 South of 2-13 the topography nses sharply and the
remaInder of the wetland IS all to the west of the property hne
Wetland 2 has palustnne emergent, scrub-shrub, and forested classes (CowardIn et al
1979) wIth areas greater than 0.25 acres The small portIOn of the wetland on the
Nisqually Estates sIte IS part of the forested class and shows few sIgns of dIsturbance
The gravel road on the adjacent property appears to have Isolated thIS part of the
wetland from surface water exchange wIth the remaInder of the wetland.
ThIS wetland IS rated a Category II wetland based on ItS large SIze, plant commumty
dIversIty, connectIOn to a perenmal fish-beanng stream, and hIgh wildlIfe value The
wetland scored 34 pOInts usmg the SIgmficant HabItat Value sectIOn of the ratIng
system (AppendIx A) Thurston County desIgnates thIS category as Class II wetlands
for the purposes of the CntIcal Areas OrdInance
Wetland SoIls --A pair of SOlI profile holes were dug In and adjacent to the larger
wetland lobe The wetland soil hole was dug 6 feet north of W 2-12 and IS marked
and labeled SP-2. An upland profile hole was dug 4 feet south of W 2-12 The
upland hole had a profile sImIlar to the Everett very gravelly sandy loam mapped for
thIS area. The wetland soIl profile IS consIstent WIth the MukIlteo soIl profile mapped

Wetland and Stream Buffers
Thurston County provIdes for undIsturbed buffer areas between wetlands and
streams and adjacent development (Thurston County CntIcal Areas OrdInance,
Chapter 17 15) Buffers are desIgned to maIntaIn water qualIty and wIldlIfe habItat
values of wetlands and to ensure that adjacent development does not adversely
affect wetlands. Buffer wIdths are based on the SIze and qualIty of the wetland and
the IntenSIty of the planned development or land use
The standard buffer wIdths adjacent to hIgh IntenSIty land use (reSIdential greater
than 1 umt/5 acres) are 200 feet for a Class II wetland and 100 feet for a Class III
wetland. The buffer WIdth may be reduced or averaged If the remaInIng buffer
contInues to effectively protect the wetland. SpeCIfic mItIgatIOn measures and
standards for redUCIng the normal buffer WIdth are IdentIfied In the CntIcal Areas
OrdInance MitIgatIng measures to reduce or average buffers Include enhanCIng the
wetland buffer, substantially ImproVIng WIldlIfe and fish use In the wetland, and
restonng degraded areas of the wetland.

answer to questions la, Ih and lc are all NO. contact the Natural Heritage
program of DNR.
1a. Human caused disturbances.
Is there significant evidence of human-caused changes to topography or
hydrology of the wetland as indicated by any of the following conditions'
Consider only changes that may have taken place in the last 5 decades. The
impacts of changes done earlier have probahly heen stahilized and the wetland
ecosystem will be close to reaching some new equilihrium that may represent
a high quality wetland.
