Additional goals include delineating and categorizing Wetland B which was flagged in the field March 3, 2008 by Alkai Consultants. The categorization and delineation for Wetland B was conducted on March 15, 2010 since a report was not submitted with the past field work, No wetlands are indicated on the Jefferson County Critical Areas Map although two large wetlands that extend off site were identified on the parcel. Wetland buffers associated with the wetlands will restrict any future development of the site. There is a pending septic permit application with Jefferson County Public Health (##SEP 07- 00293) and a septic system designed by Nathan Cleaver submitted prior to the identification, categorization, or delineation or of Wetland B. Description of Site • LegaI Description: Parcel #921 332 037, Section 33 Township 29N Range 1 E • Location. Corner of Mats Mats Beach Road and N. Bayview Drive, Port Ludlow Jefferson County WA. (Oak Bay Road to Mats Mats Beach Road) • Soils: A1C Alderwood sandy loam, (not listed as a hydric soil, Jefferson County Hydric Soil List 1191) • Slopes: 0 to 15 percent A map of the site location and mapped soils is included in the Appendix (Sheet #1). The 1.68 acre rectangular parcel consists of a mixed forest community with a typical understory of salmonberry /sedges in the wetland and salallsnowberryllrkdian plum in the upland. Although the site is undeveloped the western portion of this parcel appears to have less human impact than the eastem portion which is open and flat. Wetlands were identified on both the eastern and western edges of the parcel with a central area outside of the wetland. The wetlands are large and although separated by roadways, appear to extend off the parcel to the east, south, and west. Stowell Wetland Delineation and Analysis Report Olympic Wetland Resources Report 'File #2010 -0317 1 March 17, 2010 Methodology Fieldwork to determine the wetland boundaries was conducted according to the methodology outlined in the Washington State Wetland Identification and Delineation Manual (Department of Ecology March 1997). Specific field methodologies for plot sampling of soils, vegetation, and hydrology and boundary determinations are described in greater detail in the Appendix. All wetlands regardless of size within Jefferson County are subject to requirements outlined in the updated Jefferson County Unified Development Cade (UDC 18.22 revised March 2008, Article VII- Wetlands), with the exemption of Category IV wetlands under .O1 acres. Land use restrictions will apply to all future developments associated with this parcel. Background Information The following resources were consulted prior to field work for this project: • Jefferson County Critical Areas Map (1495) • National Wetland Inventory Map • Aerial Photographs (Soil maps pre -1975 and 2000, 2005, 2006 internet) • Jefferson County Unified Development Code (March 2048) • Soil Survey of Jefferson County (U.S. Soil Conservation Service 1975) • Washington State Wetland Identification and Delineation Manual • National List of Plant Species That Occur in Wetlands: Northwest (Region g) • Washington State Wetland Rating System for Western WA (Ecology #04 -06 -025) All wetland delineations and field reaps prepared for the previous owner (Susan Glover) were reviewed prior to this delineation. This includes the Wetland Delineation and Analysis Report by Alkai Consultants, LLC. (November 2007, for Wetland A) with additional work March 2008 (Wetland B). The Washington Department of Fish and Wildlife, Habitat and Species Map for Jefferson County indicates the presence of eagle nesting sites at Olele Point which is over 400 feet from this project area. Wetland Delineation Findings General Wetland Conditions Olympic Wetland Resources examined findings and evaluated flagged boundaries of Wetland A confirming all but one flagged location. All wetland flags were still present (A -1 through A -8) and represents only the eastern wetland edge that would affect the building site since the wetland extends off` parcel to the east. Ponded water and a dominance of obligate wetland vegetation will move one flag to the west by approximately 10 feet (A -7) as indicated on the Wetland Boundary Map (Sheet 42 Appendix). In general the wetland edge is distinct and there is both a drop in topography and a distinct change from upland to wetland vegetation. Wetland B was flagged around the entire perimeter during the previous assessment by Alkai Consultants, LLC. For the Olympic Wetland Resources delineation only the edge that would Stowell Wetland Delineation and Analysis Report Olympic Wetland Resources Report File #2010 -0317 2 March 17, 2010 affect the building envelope was delineated and flagged B -1 (20 10) though B-6 (2010), north to south, to differentiate flags from the previous flagging of March 2008. Test pits were excavated and data recorded in several Iocations to verify the wetland edge in this flat mosaic wetland complex. The edge of Wetland B is not easily defined in this area since there is neither a drop in topography nor a distinct vegetation change; hydrology was a major criterion for boundary line determination. In general this field examination agreed with the previous flagged edge. All Data Points and boundaries for Wetland B are indicated on the Wetland Boundary Map (Sheet #2 Appendix). soils Jefferson County Soil Survey Iists the soils as: AIC Alderwood sandy loam. (not listed as a hydric soil). The soil at this site did not correspond to the description of Alderwood soils since this area has been inundated for some time. Soils in Data Point 1 (DP #1), located near the neighboring parcel to the north were dark grayish brown, loamy with gravel and no mottles, (Munsell l OYR 312). This was clearly outside the wetland and soils were dry and crumbly. Soil pits in the wetland area Data Point 2 (DP #2) also consisted of a gravelly loam but were clearly hydric due to the presence of abundant and prominent mottles and a slight sulfidic odor. This soil was similar in color to the upland soil with the exception of bright mottles (Munsell 10YR 312, mottles 2.5YR 416). This data point was slightly down slope and adjacent to a ponded area which appears to be part of drainage corridor. Data Point 3 (DP#3) was in the central portion of Wetland B to confirm hydric soils. Soils at this location also had positive indicators of prolonged hydrology including reducing conditions, mottles, and low- chroma. At this location the soils had a distinct clay layer at 14 inches with mottles abundant in the upper layers (Munsell 1 OYR 312, mottles 1 OYR 316 and sub -soils 1 OYR 511) Many smaller pits were tested around the wetland boundary to verify the presence of hydric soils. Since this wetland is flat and has a mosaic of ponded and saturated soils, the wetland edge was not nearly as clear as Wetland A. [Upland islands with ferns were present throughout this wetland. Vegetation Wetland A Since Wetland A lies in a swale and is at the toe of the slight slope vegetation at the upland /wetland edge is distinct, changing from salallsnowberry to a salmonberry /sedges community. Vegetation within the wetland consists of a forested canopy of young and mature cedars, willows, and alders with a dense tangle of shrubs, and mosaics of sedges. The structural vegetation layers, habitat value, and site diversity is high in the western portion of the site around Wetland A. Wetland B The vegetation around wetland B also consists of a tree layer dominated by an alder /cedar community, however the terrain is flat and the understory open. The shrub/herb layer is dominated by salmonberry with reed canarygrass, buttercup, and slough sedge. The habitat Stowell Wetland Delineation and Analysis Report Olympic Wetland Resources Report File #2010 -0317 3 March 17, 2010 function is lower in Wetland B due to lack of interspersion of habitats, the presence of invasive species, nearby roadways, and neighboring development. Upland area between Wetlands A and B is comprised of a mix of alders and firs, (Douglas and grand fir) with an under story dominated by salal, Indian plum, and snowberry. The distance between the delineated edge of Wetland A and Wetland B Varies from 130 to approximately 220 feet. Several mature trees are growing within upland islands and along the wetland edges. Within the buffer of Wetland A several Douglas' fir measured 88 "DBH, and within the buffer of Wetland B several cedars measured 124" DBH. The upland shrub layer is comprised of snowberry, elderberry (often overlapping into wetland areas) and salal. The herbaceous layer was dominated by sword fern which were also found on hummocks within both Wetland A and B.

Plants classified according to the Fish and Wildlife Service; 1988,1993 Update Stowell Wetland Delineation and Analysis Report Olympic Wetland Resources Report File #2010 -0317 4 March 17, 2010 Hydrology An outlet was observed in the southwest corner of Wetland A. This outlet consisted of a culvert under Mats Mats Beach. Road where water was flowing to the parcel across the road on March 15. The specific source for water feeding Wetland A was not observed The source of hydrology for Wetland B is from a Swale slightly upslope on the neighboring lot, roadway runoff and possibly the larger wetland across North Bayview Drive. Ponded water to depths of 5 inches was measured at the northeast corner. Water was observed in the soil test pits, as surface saturation, and within shallow ponds throughout the wetland. Water measured from 9 to 12 inches below the surface at Data Point 2 and 3 and was observed in old perk holes that were left open near the wetland boundary. No outlet for to Wetland. B was observed. Wetland Analysis Results Wetland Categorization Both wetlands were rated using the Washington State Wetland Rating Field Data Form (Department of Ecology 904 -06 -025 with October 2008 updates). Wetland A, previously rated as a Category III wetland, was re- evaluated using this updated Data Form. Based on the score for Water [duality Functions (30), Hydrologic Functions (5), and Habitat Functions 0 8) this wetland has a total of 53 points. All wetlands with scores between 51 and 69 points are Category 11 wetlands. The rationale behind this categorization is that there is the potential to improve water quality from urban and roadway runoff and development. The hydrologic functions are low to moderate since there is little potential to reduce flooding or erosion since the water flows off site. The habitat function is moderate due compromised buffers, however structural diversity is high and there is potential for wildlife habitat. Wetland B qualifies as a Category III wetland based on the score for Water Quality Functions (24), Hydrologic functions (5), and Habitat Functions (14) to total 43 points. All wetlands with scores between 30 and 50 points are Category III wetlands. The rationale behind this categorization is that there is moderate opportunity for water quality improvement since there is potential to filter water from nearby roads and adjacent development. The hydrologic functions are low to moderate since the water has no outlet and is retained on site. The habitat function is low due the presence of invasive plants, no interspersion of habitats, and broken wildlife corridors. Buffer Requirements This parcel and development qualifies as moderate impact land use (single - family residential use on parcels of one (1) acre of larger). All buffers are measured perpendicular from the delineated edge (Jefferson County UDC Critical Areas, March 2008, Buffers Table 18.22.330(3)). Wetland A has been rated as a Category 11 Wetland. In Jefferson County the standard buffer width for a Category 11 Wetland is 75 feet since the Habitat Function score is less than 20 points. Wetland B is a Category III Wetland and will have assigned buffers of 60 feet due to a low Habitat Function Score. Stowell Wetland Delineation and Analysis Report Olympic Wetland Resources Report File #2010 -0317 5 March 17, 2010 Summary This wetland report verifies the accuracy of the wetland boundary established by Alkai Consulting (November 2007). The wetland was categorized using DOE Data forms to comply with the current Jefferson CAO adopted March 2008. To this end the Wetland A rates as a Category II wetland with 75 foot buffers. Wetland B was confin-ned March 2008 but was not formally delineated or categorized. Wetland B was delineated March 15, 2010 and qualifies as a Category III wetland with 60 foot buffers. Both wetlands extend off site but are bisected by roadways. The distance between Wetland A and Wetland B is between 130 to 220 feet with buffers overlapping in the central portion of the parcel. The majority of the parcel falls within wetlands or wetland buffers. Limitations Wetland status depicted in this report has not been confirmed by a government official, fmal authority over both Wetland A and Wetland B determinations rests with the governmental agencies. Jurisdictional authority over wetlands rests with the local, state and federal agencies. All information in this report should be reviewed by the appropriate regulatory agencies prior to approval.

Chapter 173 -22 of the Washington Administrative Code requires that all wetlands within the State of Washington be delineated using this manual. All wetlands within Jefferson County are regulated according to the Jefferson County Unified Development Code, (Critical Areas 18.22 revised March 2008). The methodology outlined in the Washington State Wetland Identification and Delineation Manual requires examination of the three parameters for a positive wetland determination: hydric soils, hydrophytic vegetation, and hydrology. For an area to qualify as a jurisdictional wetland it must have a positive indicator from all three parameters. All wetlands identified using this methodology may be federally regulated, regardless of size. The subject parcel was initially examined to identify plant communities, potential wetlands, topographic features, hydrology sources, and drainage patterns. It was determined whether human impacts to the site would significantly alter the wetland, Hydrophytic Vegetation Criterion: Wetland plant species must, under normal circumstances, constitute greater than 50% of the total vegetation present to meet the qualification as a site dominated by hydrophytic vegetation. Dominance of plant species is determined by calculating actual aerial cover within a 30 -foot radius for trees and woody vines, and a 5 -foot radius for herbs and saplings /shrubs at each data point. Commonly occurring plant species have been rated by the United States Fish and Wildlife Service (USFWS) National List of Plant Species That Occur in Wetlands: Northwest (Region 9), as to their frequency of occurrence in wetlands and non - wetlands. During the fieldwork, each species was recorded and given a rating based on percent cover and indicator status, obligate wetland (OBL), facultative wetland (FACW), and/or facultative (FAC). Hydrophytic Soil Criterion: A hydric soil is a soil that forms under conditions of saturation, flooding, or ponding lasting long enough during the growing season to result in an anaerobic upper layer (USDA -NRCS 1995). Hydric soils favor the growth and regeneration of hydrophytic vegetation. The indicators for this type of soil include low chroma, mottles, gleying, and high organic content within the soil immediately below the A- horizon or 10 inches (whichever is shallower). A soil profile to a depth of 16" was extracted from each sample plot test pit where soil colors (including value and chroma) and textures were recorded. Soil colors were analyzed using the Munsell Soil Color Charts (1992). Wetland Hydrology Criteria: Wetland hydrology is defined in the Washington State Wetland Identification and Delineation Manual as "areas which are seasonally inundated and/or saturated to the surface for a consecutive number of days" at least 12.5% of the growing season (20 days out of 258 days). For most of Western Washington at low elevations, the mesic growing season is March l to October 31, has been considered a good rule. The growing season has also been defined when soil temperatures at 19.7 inches below the soil surface are higher than biological zero (41 degrees F). Indicators of hydrology may include, but are not necessarily limited to, ponded water, drainage patterns, drift lines, sediment deposition, historic records, water- stained leaves, cracking of the soil surface, oxidized root channels, and/or sediment deposits. Visual observation of soil saturation requires digging a soil pit to a: depth of 16 inches. If the water table is found within the soil test pit near twelve inches of the soil surface one can assume that soil saturation occurs to the surface. Positive signs of hydrology are omen absent during the summer and fall months but can be inferred if there are positive indicators of hydric soil and hydrophytic vegetation. Categorization Wetland categorization was determined using the Washington State Department of Ecology (DOE) Wetland Rating System Revised (Ecology Publication 404 -06 -025, August 2004), according to type and category of wetland. The wetland is assigned a numerical value for water quality function, hydrologic function, and habitat function. The total score determines the category of wetland. Wetlands are rated as entire systems and quite often exceed project boundaries. Ratings range from Category l to Category IV. Buffers are assigned according to intensity of land use for specific parcel size using final numeric scores. Category I is the highest quality wetland. They are not replaceable and therefore receive the largest buffer and highest protection. Determining Wetland Edges Wetland edges were determined by establishing pairs of data points: one within the wetland which contains positive indicators of al l three of the wetland requirements: soils, hydrology, and vegetation, and another data point outside the wetland, where one or all of the requirements were not present. The wetland edge is flagged between the pairs of points at intervals of 20 to 40 feet.
