June 29, 2007 T-Mobile USA, Inc. 19807 North Creek Parkway North Bothell, WA 98011 Attn: Pushpinder Singh Re: Wetland Determination Study for SE05198B Wilkenson Road/Railway(T-Mobile) Parcel No. 64300700600 at 16220 Railway Road SE, Yelm, WA 98597 Dear Mr. Singh: There are no wetlands on the property or within 300 feet of the proposed location of the telecommunications facility. The data points selected did not meet all the parameters for wetland classification. The soil is a non-hydric Spanaway gravelly sandy loam with a dry soil profile and no water table at 16 inches from the surface. The plant community is dominated by grasses, scotch broom, and trees. There are no wetland hydrology indicatars are present. General Site Description The property is triangular shaped and is 9.62 acres. The southeast corner is occupied with a mobile and single-family home surrounded by some deciduous trees. Further to the north is a row of Douglas-fir trees adjacent to the property boundary that runs southeast to northwest. The remainder of the property is a field with some Scotch broom. The highest elevation on the property is 340 feet situated near the mobile and single- family and slopes down to the west to the 330-foot contour(see Figure 1 attached). Methodology The wetland investigation was performed using the Routine On-Site Small Area Determination Methodology as described in Part IV, Section D of the Corps of Engineers Wetlands Delineation Manual(Corps of Engineers, 1987) and the Washington State Wetlands Identification and Delineation Manual(WA Department of Ecology, 1997). This determination is based on the presence of the three criteria for jurisdictional wetlands: hydrophytic vegetation, wetland hydrology, and hydric soils. All three criteria must be present in order to classify an area as a wetland. The wetland determination also included a review of the Thurston County GIS wetland information and the USDA Soil Conservation Service's, Soil Survey of Thurston County Area, Washington (Web Soil Survey, 2007). 402 EAST MAIN STREET, SUITE 110 AUBURN, WASHINGTON 98002 253-804-2645 / FAX 253-333-8584 Hydrophytic vegetation has developed specific adaptations in order to survive in saturated or inundated environments. The probability of species being found in wetland environments has been determined by the U.S. Fish and Wildlife Service in the National List of Vascular Plant Species that Occur in Wetlands (US FWS, 1996). An indicatar status was applied to each species according to its probability of occurring in wetlands. The dominant plant species were assessed by indicator status at several sample locations to determine if the plant communities were hydrophytic. Table 1. Plant Indicator Status Indicator Cate o S mbol Occurrence in Wetlands Obli ate Wetland OBL > 99% Facultative Wetland FACW 67-99% Facultative FAC 34-67% Facultative U land FACU 1-33% U land UPL < 1% Note: FACW,FAC and FACU have+and-values to represent species near the wetter end of the spectrum(+)and the drier end of the spectrum(-). Inundation, flooding, or saturation to the surface for at least 5% of the growing season is required to satisfy the hydrology requirements for jurisdictional wetlands. In western Washington, wetland hydrology is typically present from December to May, and the growing season is normally from mid-February to mid-November, depending upon location and local climate. The growing season can either be defined by the number of frost-free days (temperatures above 28° F) or the period during which the soil temperature, at a depth of 19.7 inches, is above biological zero (41°F). Several sample locations were examined for indicators of wetland hydrology such as saturation, inundation, water-stained leaves, sediment deposits, or drainage patterns. Hydric soils are defined as those soils that are "saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part" (WADOE, 1997). They are either organic soils (peats and mucks), or mineral soils that are saturated long enough to produce soil properties associated with a reducing environment. Such properties include a low chroma(grayish) or mottled soil matrix. In Washington State, a low chroma soil color, determined with Munsell Soil Color Charts, is the main indicator for hydric soils. Soils were assessed for hydric characteristics in an 18-inch pit at several sample locations. Local Inventories The Thurston County GIS data does not list wetlands or streams on or within 300 feet from the proposed project site. Yelm Creek is situated approximately 430 feet from the southwest corner of the property. The flood zone from Yelm Creek covers the western half of the property and approaches the 332-foot contour(see Figure 1 attached). The edge of the flood zone is approximately 300 feet from the proposed location of the unstaffed telecommunications facility. The Soil Survey of Thurston County Area, Washington (Pringle R.F., 1990) has mapped the property as Spanaway gravelly sandy loam which is not listed on the state hydric soils list(see Figure 2). June 2007 2 J.S.Jones and Associates,Inc. _ Results Sample location one (SL-1) (see attached data sheets) is in the northwest portion of the parcel (see Figure 3 for approximate locations). The plant community is dominated by grasses (Gramineae, FAC) and dandelion(Taraxacum officinale, NL). Grasses in Western Washington are typically tolerant to wet conditions and are therefore assumed to have FAC indicator status. The plant community is hydrophytic because more than 50% of the dominants are FAC, FACW, or OBL. The soil is a"somewhat excessively drained" Spanaway gravelly sandy loam (see attached soil map). From 0 to 10 inches, the soil is a very dark brown (lOYR 2/2) gravelly sandy loam. From 0 to 16 inches, the soil is a very dark grayish brown (lOYR 3/2) gravelly sandy loam. The soil is non-hydric because it has a two-chroma matrix immediately below the "A"horizon or at ten inches, whichever is shallower(Department of Ecology, 1997). No indicators of wetland hydrology were observed in this sample location. Sample location two (SL-2) is in the mid-south portion of the parcel. The plant community is dominated by bluegrass (Poa sp., FACW), orchard grass (Dactylis glomerata, FACU), rib plantain (Plantago lanceolata, FAC), red top (Agrostis gigantea, FAC), bentgrass (Agrostis, sp., FAC), and scotch broom(Cystisus scoparius, NL). Grasses in Western Washington are typically tolerant to wet conditions and are therefore assumed to have FAC indicator status. The plant community is hydrophytic because more than 50% of the dominants are FAC, FACW, or OBL. The soil is a"somewhat excessively drained" Spanaway gravelly sandy loam. From 0 to 16+ inches, the soil is a very dark brown (lOYR 2/2) gravelly sandy loam. The soil is non-hydric because it has a two-chroma matrix without mottles immediately below the "A"horizon or at ten inches, whichever is shallower. No indicators of wetland hydrology were observed in this sample location. Sample location three (SL-3) is in the northeast portion of the parcel. The plant community is dominated by ash (Fraxinus sp., FACW), orchard grass, tall fescue (Festuca arundinacea, FAC-), bentgrass, and ryegrass (Lolium sp., FACU). The plant community is non-hydrophytic because no more than 50% of the dominants are FAC, FACW, or OBL. The soil is a"somewhat excessively drained" Spanaway gravelly sandy loam. From 0 to 16+ inches, the soil is a very dark grayish brown (lOYR 3/2) gravelly sandy loam. The soil is non-hydric because it has a two-chroma matrix without mottles immediately below the "A"horizon or at ten inches, whichever is shallower. No indicators of wetland hydrology were observed in this sample location. Sample location four(SL-4) is in the southeast portion of the parcel. The plant community is dominated by ash trees, ryegrass, orchard grass, and bluegrass (Poa sp., FACV�. The plant community is non-hydrophytic because no more than 50% of the dominants are FAC, FACW, or OBL. The soil is a"somewhat excessively drained" Spanaway gravelly sandy loam. From 0 to 16+ inches, the soil is a very dark brown (lOYR 2/2) gravelly sandy loam. The soil is non-hydric because it has a two-chroma matrix without mottles immediately below the "A"horizon or at ten inches, whichever is shallower. No indicators of wetland hydrology were observed in this sample location. June 1007 3 J.S.Jones and Associates,/nc. Sample location five (SL-5) is in the northwest portion of the parcel. The plant community is dominated by unidentified grass, bentgrass, rib plantain, and red top. Grasses in Western Washington are typically tolerant to wet conditions and are therefore assumed to have a FAC indicator status. The plant community is hydrophytic because more than 50% of the dominants are FAC, FACW, or OBL. The soil is a"somewhat excessively drained" Spanaway gravelly sandy loam. From 0 to 16+inches, the soil is a very dark brown (lOYR 2/2) gravelly sandy loam. The soil is non-hydric because it has a two chroma matrix immediately below the "A"horizon or at ten inches, whichever is shallower. No indicators of wetland hydrology were observed in this sample location. Off-site Areas Any off-site wetland buffer that could potentially extend on the property is interrupted by Railway Road S.E. to the South, Rhonton Road S.E. to the west and a railroad to the north. The adjacent property to the east (Tax Parce164300700500) has an electrical sub- station situated approximately 50 feet to the east of the single-family home. There are no visible wetland indicators between the sub-station and the single-family home. The area north of the sub-station is a field that has vegetation similar on the subject property. The field is on the same elevation as the proposed project and does not have visible wetland indicators. Authority The wetland determination is in accordance with Section 404 of the Clean Water Act, the objective of which is to "maintain and restore the chemical, physical, and biological integrity of the waters of the United States (WADOE, 1997)." Wetlands are defined as "areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas (WADOE, 1997)." Wetland determinations and delineations are not final until approved by regulatory agencies and/or local jurisdictions. Wetlands are subject to seasonal and annual variation. J. S. Jones and Associates, Inc. does not guarantee acceptance or approval by regulatory agencies, or that any intended use will be achieved.
