Routine or seasonal maintenance includes turf/plant care, fertilization, disease/insect control, irrigation, trash removal/litter control, cleaning/repair of surfaces and structures, and other general maintenance needs. Turf/Plant Care Turf shall be cut cleanly at a height appropriate for the type of grass and mowing conditions - generally 1.5 to 2.0 inches. Mow at least once per week for irrigated and fertilized turf during the growing season; at least once per every two weeks for non-irrigated, non-fertilized turf areas during the growing season. All cut grass shall be removed from paved surfaces. Aerate two times per year. Reseed or resod as needed. Fertilizer Fertilizer shall be applied in measured amounts at frequencies appropriate to sensitivities of landscape types, as well as types of plant species and length of growing season. Fertilize turf/plant areas a minimum of four times per year to ensure adequate levels. Disease/Insect Control Disease and insect control shall be done typically when plant materials are being inflicted significantly. Cultural prevention is the most desirable strategy -through time-sensitive applications and/or integrated pest management. Irrigation Areas shall be irrigated with automatic, underground sprinkler system during the growing season. Intensity of use shall be reflective of rainfall frequency and plant/turf requirements. Irrigation shall occur daily during summer months. Trash Removal/Litter Control Remove trash as necessary, dependent on level and type of accumulation (such as trash receptacles, restrooms trash bins). Remove litter at least twice per week. Surface/StructZrre Cleaning & Repair Cleaning shall be done as necessary to ensure orderly, neat appearance. Repairs shall be done immediately after discovery and at a time least disruptive to area use. Other General maintenance such as pruning, storm clean-up, trail maintenance, plumbing/electrical repair, removal of undesirable plant types, vandalism repair, hazardous tree removal, etc. shall be conducted on an as-needed basis. Leve12: Moderate to occasional maintenance applied to passive use areas such as meadows, prairies, open water shorelines and wetland buffers. Occasional or seasonal maintenance includes plant care, litter control, repair of surfaces and other general maintenance needs. Plant Care In meadow and prairie areas control woody plant rejuvenation by mowing - or other means of cutting -once per month during the growing season. Control thistle growth and other invasive species, as needed, through manual methods. Litter Control Remove litter, as observed. Surface Repairs Repair trail surfaces, as needed. Repairs shall be done at a time least disruptive to area use. Other General maintenance such as pruning, storm clean-up, trail maintenance, removal of undesirable plant types, vandalism repair, hazardous tree removal, etc. shall be conducted on an as-needed basis. Leve13: Occasional maintenance applied to areas with little use or use confined to trails such as creek corridors, wooded hillsides and groves, and wetlands. Occasional maintenance includes plant care, litter control, repair of surfaces and other general maintenance needs. Plant Care Control undesirable plant growth (type of species and/or locations of growth) through manual methods on an as-need basis. Litter Control Remove litter, as observed. Surface Repairs Repair trail surfaces, as needed. Repairs shall be done at a time least disruptive to area use. Other General maintenance such as pruning, storm clean-up, trail maintenance, removal of undesirable plant types from shorelines, vandalism repair, hazardous tree removal, etc. shall be conducted on an as-needed basis. \ \ _ HE COOT COMPANY T Wetland and Wildlife Consulting Services 416 5 Washington Olympia WA 9H,1)1 (fib()) ~~2 997 FAX (~60) 3>?-0914 WETLANDS INVENTORY FOR THE TAHOMA TERRA PROJECT 523, 24 T17N N R1E City of Yelm Thurston County Tax Parcel Nos. 21723410000, 21724320000, 21724310100,21723440000,21724330000,21724340100 APRIL 2005 prepared for: Steve Chamberlain SCA Consulting Group 4200 Sixth Ave SE Ste 301 Lacey, WA 98503-1000 prepared by: Steve Shanewise, PWS Senior Ecologist TahomrOSinv CONTENTS Figure 1: Vicinity Map intr~duction ............................................................................1 Methods ..................................................................................2 Results ......................................................... ........................... 3 Existing Wetland Habitat ............................ ...........................4 Wetland Relevant Proposed Development ...........................7 Wetland Impacts ......................................... ...........................8 Wetland Mitigation ..................................... ...........................9 Discussion ................................................... ...........................10 Figure 2: Surveyed Wetlands Map Figure 3: Proposed Site Plan Figure 4: Soils Map Figure 5: Aerial Photo Map Appendix I: Wetland Descriptions Text Data Sheets Category Ratings References n U n ~J f-1 U f-1 U r--, n U (-1 LJ (-l U r-1 U n U '~ U n U r--, l~ n U ~J n u n U n U n U yy ,~K ~ ~ ~ 4vi -.Q~~- . x pp ~; 7440 ~ f~' ~ -~~ ~~,'" ~ ~ ~ ~~ ~ 93RD AYE SE i • s nvr sPRAG~ Si 93~~-.+- `~ .~; ~ 74.49 ~~ ~~ ~ s r O %z° '~ " O ~ p YEtM .~;"" ~~ 'fitM- ~~ ~ ~ H16HSCHOOL `~~l R ;f'- ~N- ~~i ~ ~~ 4p ~P ~r. ~a x ~. ~ - ~ ^, .,', a ` ~-~ ~ ~ ~ •r, n _-~26,~ _ ;~- Projec .27 -~~ -aza- SW BtD'iAY VALLEY RD "+Sf ~',. ~ . ,~ Area ~ ~ ~ ry`r FF ~~ ~ $ ~`~~e ~ ~~ ' ~ ~ YL i , ~a ~ 4 -, ' ~ ~ ~ vu~wuv ~ ~ 'Q~ . _ ,~ ~ unrt~t' ~~ ,-: i f .., ,. ~~ y .~.~___..s,.----r,*rx-~- -----,--__________ _________'--------~ ~ ,z4 -__- -~.~a.-----°.r~ its----- ~ w v~ r ~ FS 2-i ` \t ~ ,, °~ ,~' , ~~C~' SO47HA4ESE W ~ E ~A,a~ ~~ - .unLnaY~ o `~ ~ ~~ j ~ ' ~J~7' 107TH lP SE i _ ~"~ r S ~ tr GEp~GE RD SE ~ .NN27.07--_____ ____________ ~ S'26 t 5-27 ~ S-28 FOX Hltl RD SE c ~ d Mi' 27 71 ~-] '~`~ LIBERTY RD SE a 5 ~ ~ ~,-~,c _. _ ,~ ... - x `~ ~ a~ ,.~ v~ ~PZetz z T8E SOOT ~OMPANy Wetland and Wildlife Biology Nt TAHOMA TERRA VICINITY MAP APRIL 2005 FIGURE 1 n U n U INTRODUCTION n U This report documents the wetland and stream conditions within a 220 acre piece of property, proposed for urban, residential development. Primary wetland features focus on the centrally located Thompson Creek Channel and its headwater (mostly off-property) U wetlands. Native wetland conditions have been altered to drain some areas and create artificial surface water flows within a centrally excavated ditch. Headwater wetlands n south of this property merge into the on-property systems and create a significant, U connected habitat area. Proposed development calls for establishing maximum wetland buffers along all delineated boundaries, with some areas to be preserved for native habitat n structure while others will have landscaped buffers that foster human interaction with the U natural world. Reclaimed water from the Yelm Treatment Plant will be introduced into lined, excavated basins that will convert seasonal, flashy, disturbed emergent wetland into ~ permanent, definable open water and shallow marsh conditions. Minor, unavoidable L-' wetland impacts from a roadway access to the west side of the property will be fully ~ compensated for through restoration of effectively drained habitats using reclaimed water.

Soil inspection included comparison with the Munsell Color L' Charts (1992). General soil characteristics were derived from information ,-, contained within the Soil Survey of Thurston County, Washington. (1990); `~' Occurrence of wetland vegetation was determined through species identification, r-, estimation of dominance and then assignment of wetland indicator status; U indicator status was assigned based upon the National List of Plant Species That Occur In Wetlands (1988), Supp. (1993). n L, Wetland Category Rating The Washington State Wetlands Rating System for Western Washington (1993) was used ~ to establish Category Ratings for the wetlands. U Buffers ~ Yelm Municipal Code Title 14, Chapter 14.08 Critical Areas and Resource Lands was U used to establish buffers for this project. ~' 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.

All portions of the property were extensively grazed uplands and wetlands Indeed habitat conditions , . , throughout the property are profoundly molded by cattle grazing, especially the wetlands, n and any undeveloped open spaces designed into future development will likely experience dramatic vegetation changes once the cattle are removed. In particular, the sprouting of woody vegetation, especially within existing emergent wetland habitats, n would seem unavoidable without constant intervention to eliminate the sprouts that were U previously cropped by cattle grazing. r' EXISTING WETLAND HABITAT L~ Native Wetland Conditions '-' Most wetland conditions delineated within this property represent native habitats that U have been altered. The extent of wetlands within this property has been reduced through past drainage actions that diverted surface flows and effectively drained some previously ~ wet conditions across the low-lying, gravelly-well drained Nisqually soils u , . Thompson Creek Channel U The Thompson Creek Channel is an artificial ditch excavated across this property from south to north. A native, defined stream channel condition for this system probably did r-, not occur until well north of this property. The excavated channel also extends well south of this pro ert with two branches that connect to lar er headw t tl d Alth h ~ p y, g , a er we an s. oug the Thompson Creek Channel is well-healed from its past construction disturbances and ~ supports high-quality, well functioning wetland habitat, it has a somewhat unnatural blend of Riverine and Palustrine wetland conditions due to its artificial origin. r~ Ditch Berm Failure U The Thompson Creek Channel has a break in the impounding side-cast banks that line the excavated trough through wetland areas. This break allows surface waters to leak east ~ back into the native wetland area that originally occurred here. If this failure were repaired, the water supply to the wetland east of the channel would be significantly (~ reduced, likely causing an equivalent reduction in the extent of technical wetland conditions. Wetland conditions would probably not disappear, but the edges would U recede and the extension north along the outfall might disconnect. ~ Heavily Grazed Conditions U Grazing impacts to wetlands are significant. Trampling and the cutting of sod by hooves has probably been equally as significant as the actual eatin of ve etation F rt i n g g . or ce a n, woody vegetation would be much more pirominent within the wetland plant community were it not for the influences of cattle.

V n ~1 n n 'u n Ls n V Ls r--, U u n U n U n U n u n u n U CLASSIFICATION This wetland is primarily a forested habitat but also contains areas of shrub and emergent conditions. On-property forested habitats are dominated by Oregon ash (Fraxinus latifolia) but, mostly lack a dense shrub understory due to heavy cattle grazing impacts. On-property emergent habitats are also severely influenced by grazing, and are dominated by hardy, invasive annuals. Southern portions of the system, including off-property areas, are associated with a poorly drained hydric soil formations (Norma and Muckilteo). However, northern portions of wetland engage non-hydric, excessively drained upland soils (Nisqually). These porous soils cause wetland conditions to decrease in size moving north, down-gradient along the outfall route as the hydrology drains away. Surface water is seasonal and shallow throughout the wetland, probably averaging only a few inches to a foot, but fluctuates significantly in relation to overall water conditions. At least some areas of hydric soil may remain saturated from groundwater discharge.

Where wetland conditions occurred within hydric soils, edges were mostly distinct and corresponded to the change in soil type. However, where the wetland engages the upland Nisqually soils, wetland boundaries become much less distinct, with this condition increasing moving north, down-gradient, in the system. Here, vegetation patterns were used to identify the wetland boundary, and soil saturation was an indicator of positive wetland conditions.

V CLASSIFICATION n This wetland is a partially cleared and drained system that probably represents abandoned jJ pasture land. Wetland portions within this property support a dense shrub community; areas to the south also contain emergent habitats that likely represent areas that have been ~' hayed or grazed in the past (haying may still occur). A large, central ditch (an upstream Li extension of the same ditch representing the Thompson Creek Channel for Wetland 1) has been excavated through the central part of the wetland, likely draining 1-2 feet off of `-', the persistent surface water elevation that occurred in a native condition. Existing U hydrology likely supports a foot or so of surface water seasonally, with permanent saturation possible in some of the lower wetland portions. n U Cowardin Dominant Ve etation r, PALUSTRINE Salix sp (willow) Scrub-Shrub, Broad Leaved Deciduous Corpus stolonifera ~ Seasonally flooded, Fresh Mixed emergents r-, Mineral and Organic Ditched u n U BOUNDARY DELINEATION The on-property portion of this wetland occurs mostly along the toe of a narrow roadway (~ cut along the edge of the system and the adjacent, abrupt, steep slope.
