(Alkai) has been authorized by Judy Surber to perform wetland delineation and analysis along the Howard Street and Rainier Street corridors between Discovery Road and Sims Way in Port Townsend, Jefferson County, Washinglon (See Figure 1, Site Vicinity Map). Fieldwork was performed on February 28, March 1, and May l5 and 16,2007 . The purpose of the study is to provide critical area information for a planned road extension connecting unopened portions of the Howard and Rainier Street right-of-ways. For the pu{poses of federal, Washington State, and City of Port Townsend jurisdictional oversight, methodology used for the wetland delineation is consistent with the definition provided in paragraph 25a of the Washington State Wetlands Identification and belineation Manual (Washington State Department of Ecology [Ecology] 1997). The sections below provide: (l) an introduction to the site; (2) a description of methods used in the field delineation; and (3) technical results. GENERAL SITE CONDITIONS The study area is located in the southeast quarter of Section 9, Township 30 North, Range 01 West (Figure 1). The study area is approximately 30-acres in size, and includes the followins public right-of-ways: Howard Street, Rainier Street, Shasta Street, Sims Way, 6'h Streei Ztn Str.i, 9th Strelt, 10th Street, Discovery Road, and l3th Street. Sims Way, Discovery Road and portions of Howard and Rainier Street rightof-ways contain roads. A publicirail travels along the Howard Street corridor between 7th Street and Discovery Road. The remaining right-of-ways are unimproved. Private parcels in the study area include 001094033, 997801201, 997800501, 997800502,997800401, and 997800402. Permission could not be obtained for access to these parcels and so study was limited to public right-of-ways. Wetlands and potential wetlands in the study area have been labeled by letter A, B, C, etc. through M (See Figure 2, Study Area). The site is flat with slight depressions and a slight grade sloping down to the south. The area consists largely of undeveloped pasture, shrubs and forest. Forested areas are dominated by Douglas-fir, ALKAI Consultants. LLC .9465 Provost Road NW. Suite 202 . Silverdale, Phone: (360) 613-2407 .

Shrub communities are colonizing pasture edges and are dominated by Nootka rose, snowberry and Himalayan blackbeny. Pastures are dominated by grasses such as colonial bentgrass, meadow fescue, tall fescue, soft chess and sweet vernalgrass. METHODOLOGY Review of Existing lnformation Consistent with procedures detailed in the Washington State Wetlands Identification and Delineation Manual (1997 Manual) (Ecology 1997), ALKAI gathered preliminary information on the project site prior to the field review and delineation. General information sources included: United States Geological Survey (USGS) topographic maps, 1974 United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWD maps, Soil Survey of Jffirson County Areo, Washington (United States Department of Agriculture [USDA] 1977), and Port Townsend Municipal Code (PTMC) Chapter 19.05 Critical Areas Ordinance. Field Delineation Methodology used for wetland delineation was consistent with the technical approaches articulated in the 1997 Manual. This document is the wetland delineation manual that is used in determining wetland areas when applying state and local government regulations under the Shoreline Management Act and the Growth Management Act in Washington State. The extent and location of project related wetlands were determined during field work performed on February 28, March 1, and May 15 and 16,2007. Field work was conducted under a variety of weather conditions, from the beginning of the growing season when dormancy was ending for several plant species to late spring and flowering season for many grasses. The time of year and recent precipitation history were considered in assessing the type and extent of wetlands and stream typing presumed to exist on and in proximity to the site. Wetlands identified during field work are considered potential wetlands until their presence is confirmed through City of Port Townsend, Washington State Department of Ecology or U.S. Army Corps of Engineers review. Specific field methodology used in determining the extent and location of wetland areas include: l As part of the initial project site reconnaissance, the site was walked to determine the general extent and location of potential wetland areas; 2. Wetland and upland sample plots were established in the identified potential wetland areas and in the adjacent upland area; and 3. Wetland boundaries were delineated with flagging by noting localized topography ALKAI Consultants, LLC o Q/,$5 Provost Road NW, Suite 202 o Silverdale, Washineton 98383 Phone: (360) 613-2407 o Fax: (360) 613-2408 Howard Street Wetland Delineation ACL07W34l July 31,2007 Page 3 of9 and vegetation patterns and comparing parameters of hydrology, soil, and vegetation with data collected at the wetland and upland sample plots. Specific field methodologies for plot sampling; hydrology, soil, and vegetation evaluation; and boundary delineation are described in Appendix A. Data collected at each sample plot were entered onto a Routine Wetland Determination Data Form (Ecology 1OOl1. Copies of data forms for each sample plot are provided in Appendix B. WETLAND AND STREAM EVALUATION The subject wetlands were characterized using the wetland classes defined by the Cowardin system (Cowardin et at. 1979). The Cowardin system describes wetlands by the plant communities, soils and hydrologic regimes present. The naming convention was developed by the USFWS for the NWI maps. Wetlands were also classified and rated usingihe categories set forth in PTMC 19.05.110, which defines wetland categories according to the Revised Washington State Wetland Rating System for lilestern Washinglon (Hruby 2004). This system identifies various complexities within wetland structures, habitat attributes and various functions associated with wetlands. The rating forms completed for these wetlands are provided in Appendix C. BACKGROUND INFORMATION Watershed The study area is located in a watershed referred to as Basin 11 (Polaris 1993). No streams exist in or near the study area; however Critical Drainage Areas are shown on the port Townsend Sensitive Areas Map in the center of the study area and to the north and south (Figure 3). Jefferson County Soil SurueY The soil survey of Jefferson County indicates one onsite soil type, CmC Clallam gravelly sandy loam, 0 to 15 percent slopes. This is a well-drained upland soil in the ia"onomic sub-group Vitrandic Xerochrepts. A more detailed description of this soil is presented in Rppendix n. Soil location is illustrated in Figure 4 - Jefferson County Soil Survey map. National Wetlands lnventory The National Wetlands Inventory shows one wetland in the vicinity, a freshwater emergent seasonal wetland east of the study area between Cliff and Eddy streets south of Discovery Road (Figure 5). No other wetlands are inventoried on NWI maps within one- half mile of the study area. Port Townsend Sensr'five Areas Map The Environmentally Sensitive Areas (ESA) map shows nine inventoried wetlands in the study area. From south to north these include the following (Figure 3): .

No other State Candidate Species, Threatened, Priority or Other Priority Habitats are located within one-half mile of the subject parcel. The National Heritage Features Associated with Wetlands Data does not list this section of land for rare plant species. WETLAND DELINEATION RESULTS General Wetland Conditions The study area contains small seasonal freshwater wetlands and seasonally wet areas where one or more wetland indicators were lacking. Wetlands and potential wetlands studied by Alkai were given a letter A through M to identify them (Figure 2). Potential wetlands which were studied but which did not meet wetland criteria are referred to as "Areas" such as Area B, Area E, etc. Areas that did meet wetland criteria are referred to as "Wetland" A through M. Emergent, shrub-scrub and forested wetland plant communities were found. Emergent plant communities consisted largely of previously mowed and/or grazed pasture and covered the majority of the study area. At the time of fieldwork in May no mowing or grazing had occurred since the previous growing season which allowed meadow species to flower and be identified. Colonizing shrubs along pasture margins accounted for approximately one tenth of the study area. Forested areas to the north and south covered approximately an eighth of the area. All of the wetlands were in shallow depressions with seasonal inundation or saturation. Surface flow was observed from the south of the wetland A after times of high precipitation, but no streams were found. Wetland A A portion Wetland A within the 6th Street right-of-way was delineated. This wetland is a seasonally inundated, forested wetland with a small portion to the north of emergent wetland (pasture).

A sandy silt loam was observed in the first three inches below ground ,,rriur", with a low matrix chroma of 10YR 2/1 (Munsell reading) indicating hydric soils. Soils from three to fifteen inches below the surface were observed to be a gravelly loam exhibiting a low matrix chroma (1OYR 2/1). From fifteen to sixteen inches a compacted very gravelly till was present, with a matrix chroma of 1OYR 3/1 with mottles 1OYR 5/6. The soil column was saturated to within one inch of the surface with free watet at 2 inches and surface ponding within three feet west of the pit. Corresponding upland test pit (DP-2) was located to northeast of DP-l between wetland flags A-3 and A-4 (Figure 2). The first four inches of soil consisted of sandy loam (lgYR 212) withno mottles. The soil from four to sixteen inches below ground surface was observed to be a sandy loam exhibiting higher matrix chroma (l0YR 3/3). Upland soil characterization is similar to that desuibed as Clallam gravelly sandy loam, 0 to 15 percent slopes in the Soil Survey of Jffirson County Area (USDA 1973). Hydrology Test pit DP-l revealed that wetland hydrology criteria were met by observation of free water at two inches below soil surface, saturation to one inch in the pit and inundation to seven inches above surface three feet west of the pit. A shallow basin topography with a layer of compact till at fifteen inches below surface is an indicator of wetland drainage patterns. Upland test pit DP-2 reached no water or saturation. No indicators of hydrology were observed in the area around DP-z. Vegetation The wetland area surrounding the test pit DP-l had vegetation consisting of quaking aspen (Populus tremuloides, FAC+), Scouler's willow (Salix scouleriana, FAC), Nootka roi" (Rosa nutkana, FAC), spirea (Spiraea douglasii, FACW), and snowberry (Symphoricarpos albus, FACU). Greater than 50 percent of the dominant species were identified as facultative (FAC) or wetter and therefore met the wetland criteria for hydrophytic vegetation (Appendix B). The upland vegetation was distinct from the wetland vegetation, generally consisting of Douglas-fir (Pseudotsuga menziesii, FACIJ), Pacific madrone ('4rbutus menziesii, no indicator status), Nootka rose (Rosa nutkana, FAC), and salal (Gaultheria shallon, FACU). The only accessible upland near the northern wetland boundary consisted of mowed pasture and this is where DP-2 was located. Grasses could not be identified at the time of preliminary field work in February. ALKAI Consultants, LLC o 9465 Provost Road NW,Suite 202 o Silverdale, Phone: (360) 613-2407 . Fax: (360) 613-2408 Washinston 98383 Howard Street Wetland Delineation ACL07W341 Jlly 31,2007 Page 6 of9 Area B An area of seasonal saturation, Area B, was found on the 7th Street right-of-way which extended north and south approximately 50 feet onto private parcels 99780120I, 997800501 , and997800502 (Figure 6). A data point (DP-3) was established on the right- of-way and a corresponding test pit DP-4 was located 25 feet upslope to the east. Area B is pasture and had seasonal saturation at two inches below the surface in February. No other indicators of hydrology were found and saturation was absent in May. The soil profile at DP-3 exhibited a low matrix chroma (10YR 3ll to four inches) and mottles (10YR 412 matrix with 10YR 514 mottles from four to sixteen inches), indicating seasonally hydric conditions. In May, two out of seven dominant plant species were determined to be hydrophytic, less than the 50 percent required for wetland criteria. Therefore this area was judged not to be a wetland. DP-4 yielded similar results, with no indicators of hydrology, mottled soils with a higher matrix chroma (1OYR 3/3) and less hydrophytic ve getation. Wetlands C and D Two small previously inventoried wetlands, Wetlands C and D, are shown on the ESA map on the westem half of parcel 997800501 owned by Donald Enfield of Kelso, Washington. Permission could not be obtained for access to these wetlands. From a distance, a shallow depression with a change in vegetation type could be observed and it is assumed that seasonal, emergent wetlands are present. Total size of the two wetlands, which appear close enough together to be considered one wetland unit, is estimated to be 1500 square feet. Areas E and F An area of seasonal ponding was found on the 9th Street right-of-way close to the location shown on the ESA map. An additional low area of seasonal saturation was also present at the eastern end of this right-of-way near Howard Street. Data points DP-7, 8 and 9 were located in the 9th Street right-of-way east to west from Howard Street. DP-7 is in Area F, DP-9 is in Area E and DP-8 is between the two low areas. At DP-9 ponding to four inches was present in March but had completely dried out in May, revealing sediment deposits. Low chroma soil matrix with mottles was found at DP-9 to sixteen inches below surface indicating hydric soils. Vegetation, however, was not greatly influenced by this seasonal hydrology. Three out of seven dominant plant species (43%) were found to be FAC or wetter, failing to meet wetland criteria. DP-7 in Area F revealed seasonal saturation to three inches below soil surface in March and none in May. No other signs of hydrology were present. Soils were sandy loam with low matrix chroma to eleven inches indicating hydric conditions. From seven to eleven inches mottling was not prominent or commoq but was two units of value higher than the matrix. The plant community was less hydrophyic than at DP-9, and Area F failed to meet wetland criteria. DP-8 found less hydrology in March than the nearby Data Points and similar soil conditions and vegetation. ALKAI Consultants, LLC t 9465 Provost Road NW, Suite 202 .

DP-5 was located approximately 25 feet south of the 10th Street right-of-way where it intersects with Discovery Road. Soils were clay with low matrix chroma and mottles, indicating hydric soils subject to seasonal hydrology. In March, water was present at seven inches below soil surface with saturation also at seven inches. A small muddy patch was present showing a slight amount of sediment deposits. Vegetation assessed in March gave a l00-percent hydrophytic species result and a positive FAC-neutral test. However, in May numerous other emergents became identifiable bringing the vegetation parameter well out of the wetland indicator range. In May it became clear that only 38 percent of the dominant vegetation was FAC or wetter. Therefore Area G was judged not to be a wetland. Wetland H An emergent, depressional wetland was observed on private property .in the northeast corner of parcel 997800401near the corner of the Howard Street and 10'n Street right-of- ways. This parcel is owned by Peter and Candice Raab, and the Charles and Amy Arthur Trust of Quilcene, Washington. Permission could not be obtained for access and so observations were made from nearby public right-of-ways. Ponding in this area was somewhat more extensive in size and long-lasting than at other nearby low areas, but was still gone by May 16th. It is assumed that a seasonal, emergentlshrub-scrub wetland exists in this location. On-site study would need to be done to confirm this. Wetlands l, J, K, L and M These wetlands were previously delineated by Loggy Soil and Wetland Consulting, (Loggy, 2005). The closest wetland to the intersection of Discovery Road, Rainier Street and the 10th Street right-of-way is Wetland L ata distance of approximately 275 feet. Wetland I and J are approximately 300 feet northeast of this intersection. Wetlands I, J and L were examined to see if conditions had changed since the Loggy study and to rate them based on the Revised Wetland Rating System for Westem Washington. Wetlands K and M are farther away and were not rated, but were observed to see if conditions had changed. Wetland I is a shrub/scrub wetland. Wetlands J through M are forested. Wetland L has an emergent class of vegetation in addition to a forested class. All of the wetlands exhibit seasonal hydrology. Wetlands I through M are depressional wetlands, likely connected historically but now separated by Discovery Road and Rainier Street. Wetland I is the largest unit at an estimated 1,500 square feet. The other wetlands are approximately 500 to 1,000 square feet in size. Wetlands L and M are greater than 30 feet apart, making them not a wetland mosaic. The same is true of Wetlands J and K.

Permission could not be obtained for access to previously inventoried Wetlands C and D and suspected Wetland H, and these were not rated. An estimated rating for these wetlands is provided in the discussion that follows. All wetlands in the study area were classified as Depressional wetlands. Based on functional attributes associated with the wetlands including habitat, water quality, and hydrology functions, they have been rated as follows (see Appendix C for rating forms): WetlandA Wetland A scored 39 points on the state rating form, and therefore is a Category III wetland. The score for water quality functions in this wetland was 18, hydrological functions scored 7, and the score for habitat functions was 14. Wetland I Wetland I scored 26 points on the state rating form, and therefore is a Category IV wetland. The score for water quality functions in this wetland was 14, hydrological functions scored 5, and the score for habitat functions was 7. Wetland.I Wetland J scored 30 points on the state rating form, and therefore is a Category III wetland. The score for water quality functions in this wetland was 14, hydrological functions scored 5, and the score for habitat functions was I 1. Wetland L Wetland L scored 31 points on the state rating form, and therefore is a Category III wetland. The score for water quality functions in this wetland was 14, hydrological functions scored 5, and the score for habitat functions was 12. All Category III and IV wetlands greater than 1,000 square feet are regulated wetlands per PTMC 19.05.110(CX2). Habitat scores of Wetlands A, I, J and L were less than 20 points. Planned development of streets in the study area as part of a Local Improvement District is considered moderate impact level development. According to PTMC Tables 19.05.110(E)(3)(a) and (b), the buffers and total setback distances will be as follows: ALKAI Consultants, LLC o QQ$5 Provost Road NW, Suite 202 r Silverdale, Washington 98383 Feature Category Habitat Dev.

These wetlands are approximat ely I20 feet south of the 9th Street right-of-way where the proposed street improvement would occur. Suspected Wetland H is estimated to be a Category IV wetland of approximately 1,000 square feet in area. Since this is at the regulatory threshold for size, delineation and measurements would have to be made to confirm whether or not it was jurisdictional. Wetland H is approximately 180 feet east of the Shasta Street right-of-way where the proposed street improvement would occur. SUMMARY This wetland report documents the presence of wetlands within the study area along the Howard and Rainier Street right-of-ways near Sims way and Discovery Road, in the City of Port Townsend, Washington. Wetland A, J and L meet the City of Port Townsend's wetland classification criteria for Category III wetlands, requiring 75-foot buffer/setback distances, and Wetland I meets the criteria for a Category IV wetland requiring a 55-foot buffer/setback distance. Previously inventoried Wetlands C and D are estimated to be Category III wetlands with low habitat scores. Wetland H is estimated to be a Category IV wetland with a low habitat score. A possible street alignment is shown in Figure 6 which minimizes potential impact to sensitive areas and gives the greatest distance from potential buffers for Wetlands C, D and H. 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. Our estimation for the accuracy of the unconfirmed wetland boundaries portrayed within this report is > 957o. Respectively Submitted, ALKAI Consultants, LLC.

El i= !- - ;:t - -r ::f - ::f Plot lins Pairs of data points were established to determine the presence of wetlands. The locations of these data points (labeled DP 1, 2,3...) are indicated in Figure 2. Wetland data points are labeled in blue and upland data points are labeled in orange. These sampling locations were used as sites for the collection of hydrologic, soil, and vegetative data in accordance with the methodologies set forth in the 1997 Manual. Data collected at each sample plot was entered onto a Routine Wetland Determination Data Form (Washinglon State Department of Ecology 1997). Copies of data forms for each data point are appended to this delineation report. Hvdrolow Evaluation According to the 1997 Manual, wetland hydrology is present in areas that are inundated and/or saturated to the surface for a consecutive number of days greater than I2.5 percent of the growing season (approximately 2 weeks in Western Washington). Saturation to the surface is assumed when the water table - the level at which standing water is found in an unlined hole - is found within 12 inches of the surface in a non-sandy soil or within 6 inches of the soil surface in sandy soils. A small soil test pit was excavated to a depth of 18 to 20 inches at the center of each sample plot. The extent of soil inundation and saturation as well as the depth to free water in the test pit were recorded on the Routine Wetland Determination Data Forms as an indication of potential wetland hydrology. Other recorded potential field indicators of wetland hydrology, as listed in the 1997 Manual, include oxidized channels (rhizospheres) associated with living roots, water marks on vegetation or fixed objects, drift lines, sediment deposition on vegetation and other objects, water- stained leaves, wetland drainage patterns, and hydric soil characteristics. Soil ation The presence of hydric soils was determined consistent with the 1997 Manual. Fulfillment of the technical criteria for soil can be inferred by using a combination of published soils information and field indicators. A soil profile to a depth of 16 inches was extracted from each sample plot test pit and the depth and character of each distinct soil horizon was recorded. A Munsell soil color chart (Munsell Color, 2000 rev.) was used to charactefize the soil. In accordance with the 1997 Manual field protocol, soil color, hue, and chroma was recorded for each soil profile immediately below the "A" horizon or at a depth of 10 inches, whichever is shallower. All information collected on field soil profiles was recorded on the Routine Wetland Determination Data Form for each sample plot.

Dominant species in each of the three strata (tree, sapling/shrub, and herb) were identified and recorded on the Routine Wetland Determination Data Form. The wetland indicator status of the dominant species within each vegetation stratum was used to determine the presence of hydrophytic wetland vegetation. Each species' indicator status was defined according to Reed (1993). According to the 1997 Manual an area meets the hydrophyic vegetation criteria when, under normal circumstances, more than 50 percent of the dominant species from each stratum are obligate wetland (OBL), facultative wetland (FACW), andlor facultative (FAC but not FAC-) species. Boundary Delineation After characteristics of hydrology, soil, and vegetation were compared between the confirmed upland and wetland sample plots, a boundary determination was made in the field. The wetland boundary was determined by first noting likely areas of topographic and vegetative distinction between wetlands and uplands, and then using soil borings to determine the boundary between hydric and non-hydric soils. The wetland boundary was marked with flagging spaced at a distance of approximately 20 feet.

If it is Saltwater Tidal Fringe it is rated as an Estaarine wetland. Wetlands that were called estuarine in the frst and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2.

YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe @stuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland.'Wetlands that were called estuarine in the first and second editions of the ruting system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. to3 YES - The wetland class is Flats If your wetland can be classified as a ooFlats" wetland, use the form for Depressional wetlands. 3.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the NO-goto7 wetland class is Depressional 7. Is the entire wetland unit located in a very flat arca with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF TFM HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN TIIE L|NIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 70o/o or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10Yo of the unit; classiS' the wetland using the class that represents more than 90Yo of the total area. If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than2 HGM classes within a wetland boundary, classiff the wetland as Depressional for the rating.

AreJhe water levels in the entire unit usually controlled by tides (i.e. except during floods)? @ gotrc2 YES -the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES - Freshwater Tidal Fringe NO - Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the foi"ms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categofized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Esfuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2.The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. and surface water runoff are NOT sources of water to the unit. goto3 YES - The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? -The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; ...^ _At least 30%o of the open water area is deeper than 6.6 ft (Z m)? eq go to 4 YES - The wetland class is Lake-fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? _The wetland is on a slope (slope can be very gradual), -The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. _The water leaves the wetland without being impounded?

Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE I{Y'DROLOGIC REGIMES DESCRIBED IN QTIESTIONS 1-7 APPLY TO DIFFERENT AREAS IN TFm LNIT (make a rough sketch to help you decide). Use the following table to identif, the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 70o/o or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than L\Yo of the unit; classiSr the wetland using the class that represents more than 90% of the total area. If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than2 HGM classes within a wetland boundary, classifr the wetland as Depressional for the rating.

NOTE: the connections do not have to be relatively undisturbed. These are DFW definitions. Check v,ith )tour local DFW biologist if there are qny questions. Riparian: The area adjacent to aquatic systefirs with flowing water that contains eiements of both aquatic and terrestrial ecosysterns which mutually influence each other. Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha (2 acres). _Cliffs: Greater than7 .6 m (25 ft) high and occurring below 5000 ft. -Old-growth forests: (Old-growth west of Cascade crest) Stands of at least 2 tree species, forming a urulti-layered canopy with occasional smail openings; with at least 20 trees/ha (8 trees/acre) > 81 cm (32 in) dbh or > 200 years ofage. -Mature forests: Stands with average diameters exceeding 53 crn (2 I in) dbh; crown cover may be less that 100olo; crown cover may be less lhat l00o/o; decay, decadence, numbers of snags, and quantity of large downed material is generaily less than that found in old- growth; 80 - 200 years old west of the Cascade crest. Prairies: Relatively undistulbed areas (as indicated by dominance of native plants) where grasses a:ndlor forbs form the natural clirnax plant cotrmunity. :Talus: Homogenous areas of rock rubble ranging in average size 0. I 5 - 2.0 m (0.5 - 6.5 ft), composed of basalt, andesite, and/or sedimentary rock, including riprap slides and mine tailings. May be associated with cliffs. _Caves: A naturally occutring cavity, recess, void, or system of interconnected passages -Oregon white Oak Woodlands Stands of pule oak or oak/conifer associations where canopy coverage of the oak component of the stand is25%. Urban Natural Open Space: A priority species resides within or is adjacent to the open space and uses it for breeding and/or regular feeding; and/or the open space functions as a corridor connecting other priority habitats, especially those that would otherwise be isolated; and/or the open space is an isolated remnant ofnatural habitat larger than 4 ha (10 acres) and is surrounded by urban development. _Estuary/Estuary-like: Deepwater tidal habitats and adjacent tidal wetlands, usually semi- enclosed by land but with open, partly obstructed or sporadic access to the open ocean, and in which ocean water is at least occasionally diluted by freshwater runoff from the land. The salinity may be periodically increased above that of the open ocean by evaporation. Along some low-energy coastlines there is appreciable dilution of sea water. Estuarine habital extends upstream and landward to where ocean-derived salts measure less than 0.5ppt. during the period of average annual low flow. Includes both estuaries and lagoons. Marine/Estuarine Shorelines: Shorelines include the intertidal and subtidal zones of beaches, and may also include the backshore and adjacent components ofthe terrestrial landscape (e.g., cliffs, snags, mature trees, dunes, meadows) that are important to shoreline associated fish and wildlife and that contribute to shoreline function (e.g., sand/rock/log recruitment, nutrient contribution, erosion control).

The 82 horizons range from grayish brown to dark grayish brown. The Clsim horizon is an olive-gray r.**t.d layer that is 35 to 45 percent gravel and cobbles. Depth to the cemented layer ranges from 20 to 40 inches. The 42 andbj horizons range from strongly acid to medium acid, and the Clsim horizon ranges from medium acid to slightly acid. This soil is well drained. Permeability is moderate above the cemented layer. Roots penetrate to a depth of 20 to 40 inches. This soil holds about 2 to 4 inches of water available for plants. Runoff is slow to medium, and the hazard of water erosion is slight to moderate. The soil is saturated part of the time during the rainy season, and at times water moves laterally, in places, above the cemented layer' Most of the acreage of this soil is used for growing pasture of mixed grass and alfalfa or grass and clover' Home garden crops, berr:ies, and vegetables are alio grown.
