The property is identified by Jefferson County, Washington Assessors Office as Tax Lot//921-073-017. The site contains an old barn and two open field areas separated by a riparian area which flanks a small stream. Mr. John Thomas Graham owns the property and has applied for a permit to construct a generator room/wood shed project on the site and to renovate part of the barn structure into a garage (see Figure 3). The generator room is to be a below-ground concrete box containing a generator and a compressor tank to power water delivery to the property for irrigation purposes. The generator will also provide water and power to the barn, part of which will be renovated into a garage. The property contains an existing drainfield system which provides effluent treatment for Mr. Graham's existing house on Hiller Drive. In order to ensure compliance with the Jefferson County Unified Development Code, wetlands were delineated on the side of the stream nearest to the generator/garage project (east side of stream). The methods, results and conclusions of this delineation are described in the following sections. WT7910BR. REP/070102gbs I 2.0 METHODS Wetlands were delineated in the field based on field methods recommended in the Washington State Wetlands Identification and Delineation Manual (DOE 1997). Wetland Rating was accomplished according to the Guidelines of the Washington State Wetlands Rating System (Western Washington) (DOE 1993). Methods were essentially those recommended by the U.S. Army Corps of Engineers for Routine On-Site Field Method of delineation of wetlands (U.S. ACOE 1989). Guidelines and requirements of the Jefferson County Critical Area Code were applied as applicable (Unified Development Code, Section 3, Land Use Districts 2001). Wetland plants were primarily identified in the field, with subsequent collection and keying when necessary. Plants were identified using the following sources: Cooke 1997 Guard 1995 Pojar and Mackinnon 1994 Hitchcock and Cronquist 1973 Lyons 1997 Taylor 1995 Keying of plants using magnifying lenses and dissecting microscope was used as necessary. Determination of wetland indicator status utilized regional keys published by U.S. Fish and Wildlife Service (U.S. FWS 1988). Soils were determined through field examination. Soils were dug or augured to depths of up to 18 inches using a wetland shovel, a 24" soil probe and a standard augur. Soil consistency was determined by feeling for grain size and texture. Soil moisture was determined at that time. In the event of saturated conditions in the hole, depth to standing water was noted. Soil color was determined through comparison of field samples with standard Munsell Color Charts (Munsell 1994). Soil was also examined for presence of mottles, gley and other indicators of anaerobic soil oxidation. Hydrologic conditions were determined through examination of topographic relief and drainage patterns. Soil moistness was determined by hand as indicated above and in the event of standing water, depth to standing water was noted. Field surveys were carried out by Dr. Shea on May 14 and 22, 2002. These surveys included identification of plants, wetland habitats, soils and hydrology. WT791OBR.REP/070102gbs 2 Wetlands were determined based on the Routine On-Site Field Method used by Washington Department of Ecology and the U.S. Army Corps of Engineers. Wetlands were determined by a combination of vegetation, soil and hydrology indicators. Specific transect and quadrat points were sampled along apparent wetland edges. Various points were sampled for vegetation, soil and hydrology in order to determine wetland boundaries. Appendix A contains data forms for two typical sample points from the delineated wetlands and from the associated uplands. Wetlands were staked in the field by 24 inch wooden stakes. Wetland boundaries in forested areas were indicated by use of "Wetland Delineation Boundary" flagging tape placed at appropriate points in trees and shrubs. The delineated wetland boundary were staked and/or flagged every 20-25 feet. Wetland buffer zones were determined based on field measurements and regulatory requirements and were staked in the field and marked with yellow and black striped flagging every 40-50 feet. WT791OBR.REP/070102gbs 3 3.0 WETLAND DELINEATION RESULTS 3.1 Existing Conditions The wetlands on the property appear to be associated only with the streamside riparian zone. Vegetation in this zone is a typical mixture of facultative wetland plants which occupy the streambank and, in places, a narrow riparian zone beyond the streambank (generally between 10 and 35 feet in width). 3.2 Description of Wetlands Vegetation at the Site is shown in Table 1. Generally wetland vegetation is found from the top of the stream bank along an old stream terrace and sideslope, where it becomes intermixed with upland vegetation for a distance of 0-20 feet. The wetland delineation boundary is usually found within this zone of mixed vegetation. Beyond this zone, the site appears to have been cleared for agricultural uses and is covered with typical upland field vegetation. Soils at the Site are of the Clallam-Hoypus-Dick Association as mapped by the U.S. Soil Conservation Service (1975). These are well drained to somewhat excessively drained soils underlain by glacial till, loamy sand and gravel or gravelly sand. The specific soil type is Hoypus gravelly sandy loam (0-15 percent slopes). This soil forms on glacial terraces and consists of a 3-4 inch surface layer of gravelly fine sandy loam, underlain by 6-9 inches of dark brown gravelly sandy loam. Runoff in this soil type is medium with moderately high permeability. Hazard of water erosion is slight on level areas to moderate on slopes (SCS 1975). Hydrology is typical of a small stream within an incised channel. The streambanks range from 2-3 feet deep, grading to a relatively flat terrace which extends to a 10-12 foot high bank. The topsoil extends to a depth of 4-6 inches, composed of a fine sandy silt containing small gravels. The subsoil is a dense sandy gravelly loam, similar to glacial till. Usually soils at the top of bank are moist at depths below the surface soil (below 3.3 Land Uses and Habitat Values The anticipated land use, a below-ground room for a generator, is a very low impact use. Following a brief construction period, little or no impact on habitat is anticipated. The generator will be placed in a open field adjacent to a main arterial road which provides little habitat value for animals. The project will not interfere with the riparian zone which is habitat for small mammals, deer, and a variety of birds. Aquatic organisms including fish are believed to occupy the small stream. WT7910BR. REP/070102gbs 4 3.4 Wetland T_vpes and Buffers The wetland appears to be a Type III wetland based on the Washington Department of Ecology Classification System (see Appendix A). The wetlands comprise a narrow riparian corridor along a small stream. Plants are typical species associated with an alder riparian zone. This type of wetland requires a 50 foot buffer according to the Jefferson County Unified Development Code (Jefferson County 2001). The wetland buffer and the wetland boundary have been staked in the field. The wetland boundary has been flagged with pink "Wetland Delineation" tape. The buffer edge has been flagged with black and yellow striped flagging. The Jefferson County Unified Development Code (Jefferson County 2001) also specifies that streams be protected by buffer zones. This stream (Class III) is listed as requiring a 100 foot buffer. Measurements indicate that the distance from the stream to the near edge of the generator site is 116 feet at the point of closest approach. This measurement is taken from the top of the bank of the stream channel. WT791OBR. REP/070102gbs 5 4.0 CONCLUSIONS AND RECOMMENDATIONS 4.1 Conclusions ,_ The generator room construction site is outside the 50 foot wetland buffer zone. It is also outside of the 100 foot stream buffer zone. Stakes have been left in the field to indicate these distances. Yellow and black striped stakes represent the 50 foot wetland buffer zone. Blue and white striped flagging indicates the 100 foot stream buffer zone. The barn is partially inside the stream and wetland buffers. The back 15-17 feet is within the wetland buffer. At the northwest corner, the barn is 16 feet inside the stream buffer. At the southwest corner, the barn is 33 feet inside the stream buffer. The property owner has sited the garage structure within the northeast corner of the existing barn and placed a garden area along the southern portion of the existing barn (which will be dismantled completely in this area). This should result in the garage being placed outside the stream buffer and wetland buffer. 4.2 Recommendations We recommend that the property owner proceed with application for a building permit for the Generator Room\Wood Shed and Garage Project for his property. Based on our studies and a project map submitted by the applicant, the project structures are outside the County's established buffer zones for both streams and wetlands as per the Unified Development Code for Jefferson County, Washington (Jefferson County 2001).
