The Property owner wishes to move forward with a residential development project. The purpose of the site visit was to verify if critical area (wetlands exist on the Property, and whether indicated wetlands and their associated buffers might impact future development. During the site visit I was able to survey both Properties looking for wetlands and other critical areas. A walking survey was conducted within the Property boundaries, as well as line of sight survey beyond the Property boundary on adjacent properties. A walking survey was not conducted on the adjacent properties due to private property access. Methodology included in the critical areas survey incorporated further investigation into soils science composition, hydrological conditions and vegetation types. Procedures followed were in accordance with wetland delineations outlined in the U.S. Army Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (COE 2010). Three factors that make up a wetland were considered during the site survey, assessing vegetation, soil types, and hydrologic characteristics to identify areas meeting the wetland identification criteria outlined in the above referenced materials. In order to accurately investigate the Property a map was produced through utilizing the Jefferson County Geodata mapping tool, showing wetlands and their associated buffers. Additional research utilizing the National Wetland Inventory database, Priority Habitat Species, Natural Resources Conservation Resources (NRCS) Soils Maps and the Forest Practice Application Mapping Tool (FPARS) were utilized to serve as a reference for conducting soils analysis, vegetative inventories and hydrologic conditions to confirm whether wetlands or other critical areas are present on the Property. The results revealed a dominant vegetative species consisting of; Red alder (Alnus rubra), Stinging nettle (Urtica dioica), Trailing blackberry (Rubus ursinus), Large leaf maple (Acer macrophyllum), Sword fern (Polystichum munitum), Indian plum (Oemleria cerasiformis) and Western red cedar (Thuja plicata). These vegetation types are all indicative of upland species.

After thoroughly investigating this area it was determined that there is a potential wetland on the adjacent property which ends at the Property boundary line east of the proposed building site. This section is located on the south-east section along the Property boundary (See site map). Soils samples were taken and observed on the Property in order to determine if this potential wetland extends in to the Property across the boundary line. Soil test pits were dug to 18 inches, soil profiles were analyzed utilizing the Munsell soil color chart. The results showed well drained soils at all soil pits with a color value of 10YR 4/4, which is not an indicator of hydric soils. In addition, this soil profile extended the full 18 inches and was consistent with sandy silt loam characteristics. There was no saturation or presence of the water table, nor was there any indication of water stained leaves or watermarks on surrounding vegetation. Soils are classified as Hoko gravelly silt loam and are identified through NRCS as part of the Hoko series. Hoko series soils consists of moderately deep to cemented till, moderately well drained soils formed in alpine glacial till. These soils are on till plains, and mountains. Slopes are 0 to 60 percent. The mean annual precipitation is about 130 inches. The mean annual temperature is about 49 degrees F. Hydrologic functions and their indicators were taken into consideration throughout the survey. Online maps referenced above were referenced to determine the extent of surrounding conditions and their association to wetlands in the area (See attached resource maps). The Forest Practices Application Mapping Tool (FPARS) was checked to see if any streams or bodies of water were identified for this area. Bogachiel River is adjacent to the Property to the north. There are no influences from the river due to topography features. The Property sits well above the river. There is one small tributary that receives water from sheet flow, groundwater and precipitation located on Parcel #713021014. This is a non -fish bearing tributary defined in FPARS (See attached map). The National Wetland Inventory (NWI) was mapping tool was utilized to verify if wetlands were or have ever been present within the Property boundaries or surrounding area. The Bogachiel River is classified as a R3USC code and is named as a Riverine wetland type. Description for code R3USC is as follows: R - System RIVERINE: The Riverine System includes all wetlands and deep -water habitats contained in natural or artificial channels periodically or continuously containing flowing water or which forms a connecting link between the two bodies of standing water. Upland islands or Palustrine wetlands may occur in the channel, but they are not part of the Riverine System. 3 - Subsystem UPPER PERENNIAL: This Subsystem is characterized by a high gradient and fast water velocity. There is no tidal influence, and some water flows throughout the year. This substrate consists of rock, cobbles, or gravel with occasional patches of sand. There is very little floodplain development. US - Class UNCONSOLIDATED SHORE: Includes all wetland habitats having two characteristics: (1) unconsolidated substrates with less than 75 percent areal cover of stones, boulders or bedrock and; (2) less than 30 percent areal cover of vegetation. Landforms such as beaches, bars, and flats are included in the Unconsolidated Shore class.

The water table after flooding ceases is variable, extending from saturated to the surface to a water table well below the ground surface. In addition to potential wetlands there are two tributaries identified though FPARS but only one identified during the site visit while on the Property. The second is another un -named tributary located on the adjacent property to the east, identified through the use of FPARS online maps. The first noted and observed is an un -named tributary located on Parcel #713021014. This is a non -fish bearing tributary that runs from south to north and feeds into the Bogachiel River. During the time of the site visit this tributary was dry. According to Jefferson County CAO 18.22.270 Protection Standards this is a Type "Ns" stream which has an assigned 75 -foot stream buffer. The second un -named tributary located on the adjacent property to the east (Parcel #713021016) has been identified as a fish bearing stream. All fish bearing streams within Jefferson County are classified as a Type "F" stream with an assigned stream buffer of 150 feet. In order to determine the exact boundary of this stream additional surveying will be required. The attached site map shows an approximation of the of the stream and its 150 -foot buffer. The final conclusion for this wetland reconnaissance survey for the Property is that one potential wetland was identified on the adjacent property east of Parcel #713021015 along with two un -named tributaries, one identified while onsite and the other identified through online mapping tools. Assuming that the wetland has a maximum rating of Category I, a wetland buffer no greater than 150 feet can be applied (Jefferson County CAO 18.22.330 Protection Standards). Stream buffers have been referenced and noted above. In order to further identify the size of this potential wetland a vegetative inventory was taken to identify potential wetland boundaries. Vegetation included Salmonberry (Rubus spectabilis), Herb Robert (Geranium robertianum), Skunk cabbage (Symplocarpus foetidus), Lady fern (Athyrium filix femina), Red alder (Alnus rubra), Vine maple (Acer circinatum) and White clover (Trifolium repens). The potential wetland boundary has been mapped in the attached site map with applied maximum buffer assuming this could be a Category I wetland. Identification of critical areas and their associate buffers are well represented in the site map and should help guide any future development on the Property. If a Category I classification and its associated buffer for the wetland is a determining factor for future development it is recommended site access to the adjacent property (Parcel #713021016) be granted in order for a full delineation to occur.
