The delineation was performed to identify wetlands and associated buffers that would be applicable to future development of the northern portion of the parcel. In addition, this report contains a restoration plan addressing the following unauthorized activities: 1) the removal of four trees within the wetland buffer; 2) the removal of three trees from within the wetland; 3) the modification of a slope wetland via grading and placement of rock quarry spalls occupying an area of 1000 square feet, and the excavation of two ditches that drain surface water away from the wetland. The property is located in the southwestern quarter of Section 35, Township 22 North, Range 03 West WM (Figure 1 Vicinity Map). The entire ownership is approximately 0.85 acres in size. For the purposes of federal, Washington State, and Mason County jurisdictional oversight, methodology used for the wetland delineation is consistent with the wetland definition provided in paragraph 25a of the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 1997). The sections below provide: (1) an introduction to the site; (2) a description of methods used in the field delineation; and, (3)technical results. GENERAL SITE CONDITIONS The parcel is located off of Highway 106, which also makes up the northern property boundary. Residential parcels of similar size and shape border the ownership to the east and west, and a larger undeveloped parcel borders the property to the south. Topography within the property is slightly undulating given the presence of a swale that slopes down northerly toward Highway 106. The swale contains a slope wetland within the southern third of the property. A narrow drainage meanders within the wetland. The drainage terminates within the property, and does not connect to any other regulated waters.

The slope wetland within the swale is characterized by a community of devils club, salmonberry, skunk cabbage, piggy back plant, creeping buttercup and slough sedge. The property has a history of landscape alteration, mainly throughout the northern two- thirds of the parcel. Over the last five years the property has been modified to accommodate a future building site, road access, septic, etc. The southern portion of the parcel is relatively undisturbed, containing a forested swale. Three western red cedar trees have been removed from within the wetland boundary. An additional three cedar and one Douglas fir have been removed from areas near the wetland. Approximately 1000 square feet of the northern portion of the wetland has been modified via ditching, grading and placement of quarry spalls. Two small ditches were excavated to direct surface water north and east, toward vegetated upland areas away from the wetland. A restoration plan has been prepared to address all the above mentioned wetland modifications. l Y ..r. s ` Photo 1. Slope excavation and rock quarry spalls spread within and near wetland boundary.

General information sources included: United States Geological Service (USGS) topographic maps, 1974 United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) maps, the Soil Survey of Mason County Area, Washington (USDA, 1951), and Mason County's critical areas regulations. 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 suspect wetlands were determined during field work performed on April 16'', 2010. Field work was conducted under sunny skies with an ambient temperature ranging between 45 and 50 degrees Fahrenheit. The time of year and recent precipitation history were considered in assessing the extent of the suspect wetland presumed to exist on site. Specific field methodology used in determining the extent and location of wetland areas include: 1. 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 and vegetation patterns and comparing parameters of hydrology, soil, and vegetation with data collected at the wetland and upland sample plots. The project area was investigated and data was collected at three sample plot locations. Data collected at each sample plot were entered onto a Routine Wetland Determination Data Form (Washington State Department of Ecology 1997). Copies of data forms for each sample plot are provided in Appendix A.

This is the most extensive Everett soil. The Everett series consists of somewhat excessively drained, pale-brown gravelly soils. They occur as inextensive gravel ridges on the glacial moraines or, more commonly, as fairly continuous outwash channels between ridges of Alderwood soils. They have developed upon assorted glacial till and outwash material. The rainfall is 45 to 60 inches a year. The vegetation is mainly drought-resistant madrone, manzanita, and kinnikinnick. Everett soils are droughty because the loose gravel and sandy subsoil and substratum offer little resistance to downward movement of water. The capacity of the surface soil to hold available moisture is low. A more detailed soil description can be found in Appendix B Mason Soil Survey Text. The Mason Soil Survey map is shown in Figure 4. National Wetlands Inventory The USFWS NWI map (online wetlands mapper) shows no wetlands mapped within the study area (Figure 3. National Wetland Inventory Map). The nearest mapped wetland is shown approximately one-half mile south of the property. No other mapped wetlands are located within the parcel vicinity. Department of Natural Resources Water Resource Map The Department of Natural Resources Water Resource Map shows one stream channel within the approximate parcel location. The stream is mapped as "undefined", meaning the WA DNR did not verify the presence of the stream (See Figure 5. WA DNR Water Resources Map). TWC determined no areas meeting WAC 16.222.031 definition for regulated channels are present within the subject property (See Channel Evaluation Section below). WETLAND DELINEATION RESULTS A sloped wetland was identified within the southern portion of the parcel. The wetland is located within a low gradient swale that originates south of the property. The wetland is characterized by a shrub/scrub and herbaceous community dominated by devils club, salmonberry and skunk cabbage with an overstory of primarily western red cedar.

Wetland within property. The wetland occupies approximately 1500 square feet within the subject property, but continues south off the property to occupy nearly 5000 square feet. The wetland appears to be hydrologically supported by hillside seeps, and also receives seasonal runoff from surrounding topography. The surface water outlet for the wetland appears to be two small ditches that have been recently constructed to direct surface water northeast, away from the wetland toward upland communities of Douglas fir, western hemlock, salal, Oregon grape and swordfern. Prior to the ditching efforts the wetland appears to have been confined to the sloping swale. The northern most extent of the wetland was likely defined by a transition to gravelly, well drained soil capable of infiltrating the seepage from the wetland. To define the previous extent of the wetland within the modified area, a 3-foot deep test pit was dug just north of the quarry spall lined slope. The intent being to expose a water table or identify soil conditions indicative of a previous wetland area. The photo below shows the soil profile, which indicates a gravelly sandy soil of matrix chroma 10 YR 3/2 with no standing water, seepage, or soil saturation was observed to a depth of 3 feet. Such being the case, the northern extent of the wetland was determined to be where saturation is present along the base of the rock lined slope.

The portion of the wetland within the southern portion of the property is flagged with pink ribbon. Details regarding wetland vegetation, soils and hydrology within sample plots in both the wetland and adjacent upland are discussed below. Vegetation Overstory vegetation within the wetland appears to have consists of western red cedar (Thuja plicata, FAQ. The understory community is comprised of field horsetail (Equisetum arvense, FAQ, ladyfem (Athyrium filbc femina, FAQ, skunk cabbage (Carex obnupta, OBL), slough sedge (Carex obnupta, OBL), creeping buttercup (Ranunculus repens, FACW), piggy back plant (Tolmiea menziesii, FAQ and small bedstraw (Galium trifidum, FACW+).

The understory species consist of brackenfern (Pteridium aquilinum, FACU), salmonberry (Rubus specabilis, FAC+), swordern (Polystichum munitum, FACU), Oregon grape (Mahonia nervosa, UPL), evergreen blackberry (Rubus lacianatus, FACU), himilayan blackberry (Rubus discolor, FACU), and salal (Gaultheria shallon, FACU). Soils The wetland test pits consist of muck with matrix chroma 10YR 3/1 to a depth of 12 inches deep. Hydric soil is indicated by low chroma soils equaling one. The soil profiles observed in undisturbed upland test pits were consistent with the mapped soil type, Everett gravelly sandy loam. Upland test pits exhibited a two-layer soil profile. The upper layer consists of gravelly sandy loam approximately five to eight inches deep of matrix chroma 1 OYR 3/2 and 3/4. The lower profile contained less gravel with a matrix chroma of 10 YR 4/3 and 1 OYR 4/4. No hydric soil indicators were present in upland soil test pits. Hydrology Hydrology was indicated by FAC-neutral vegetation, drainage patterns, and water-stained leaves. In addition, the test pits revealed soil saturation during the growing season and standing water in the test pits at depths of 2 to 4 inches below the surface. Upland test pits showed no indicators of wetland hydrology. CHANNEL EVALUATION A portion of the wetland was observed containing channelized flow. The channelized flow eventually goes subsurface and does not maintain a surface water or contiguous channel connection to other waters. The ditches that have been constructed to direct surface water away from the wetlands terminate within undisturbed upland areas along the eastern side of the property (See photo below). According to WAC 16.222.031 streams that have no connectivity to Type 1,2,3,4, or 5 waters are not regulated channels. Therefore, no regulated channels are present within the property.

Water within the wetland generally moves north and drains into two outlets without being impounded. Therefore, the wetland meets criteria for a Slope wetland based on functions per Washington State Wetland Rating System for Western Washington (Hruby 2004) for the purposes of rating. The wetland was evaluated based on conditions prior to the recent modifications. Based on functional attributes associated with the wetland including habitat, water quality, and hydrology functions, it has been rated as a Category II wetland, scoring 56 points on the state rating form. The score for water quality functions in this wetland is 20, hydrological functions scored 16, and the score for habitat functions is 20. According to Table 17.01.070 E of the Mason County Resource Ordinance, the base buffer width for Category II Wetlands scoring between 20 and 28 points in habitat function, within parcels intended for Moderate Impact Land Use require a base buffer width of 110 feet with an additional 15-foot building setback. Moderate Impact Land Use is described in Table 17.07.070 B of the Mason County Resource Ordinance as single-family residential lots or residential subdivisions with 1 unit/acre or less. Although this parcel is slightly less than one acre, a High Impact Land Use buffer has not been assigned. The rational being that the wetland is not located in what would be considered a residential subdivision with more than one unit per acre. The majority of the wetland is located on a 17 acre property and many surrounding parcels are greater than one acre. RESTORATION MEASURES Slope Restoration The northern portion of the wetland has been ditched and in one location excavated and graded to a contour steeper than that of surrounding topography. The excavated and graded portion is lined with rock quarry spalls. Native material is left in scattered mounds around the wetland. The total area that has been modified occupies approximately 1000 square feet. To adequately restore this area to conditions that existed prior to modification, it is recommended that the rock quarry spalls be removed and the area restored to a slope that is consistent with surrounding topography. The currently piled native material should be returned to the hillside and the slope should be recontoured using an excavator. The slope should be returned to a gradient of approximately one-foot drop in elevation per every four horizontal feet.

Slope to be returned to original grade,rock quarry spalis to be removed,and area to be replanted. Ditch Abatement Two small ditches have been excavated, one beginning from the base of the rock lined slope, and one just above the slope. The ditches are currently draining surface water out of the wetland. The ditches terminate to the north of the wetland where the directed water infiltrates into well drained soils (shown in the photo 7 above). Each ditch should be backfilled with the native soil currently piled adjacent. This will restore the hydrological conditions that existed prior to modification. Vegetation Restoration Following the rock quarry removal and landscape topography restoration, the entire restored area should be replanted with native vegetation. Currently, western red cedar and salmonberry are present within both the wetland and the portion of the wetland buffer within the property (see photo 7, undisturbed upland area). These species are recommended to be planted throughout the majority of the restoration zone. These species are chosen based on their presence within the vicinity of the restoration site, versatility and preference to the onsite soil conditions. Trees should be planted at a density of 10-feet on center, and salmonberry should be spaced in between the trees at an average of 5-feet on center. To fulfill the recommended planting density, 10 trees and 30 shrubs will be planted within the restoration zone. Planting timing and guidelines are discussed below. Restoration for Overstory Tree Removal Three western red cedar and one Douglas fir have been removed from within the wetland buffer, and three western red cedar have been removed from within the wetland. According to the Mason County Resource Ordinance, trees removed from within wetlands and wetland buffers shall be replaced at a ratio of 6:1. Therefore, since four PO Box 2854 Belfair,Washington 98528-Cell Phone 360-620-0618.Office Phone 360-372-2421•wetlandcorps@hotmail.com 1 Parcel 322353200070 Wetland Delineation TWC 10-W46 April,2010 Page 12 of 20 trees were removed from the wetland buffer, 24 trees should be planted throughout the wetland buffer. Since three trees were removed from within the wetland, the ratio requires that 18 trees be planted throughout the wetland. Planting guidelines are addressed below. Planting Timing & Guidelines Typically, planting should occur during winter dormancy. The optimum time for planting is during February and March, however, the need to complete the project in a timely manner may call for planting to occur outside optimum time periods. All installed vegetation shall be marked with colored flagging to facilitate monitoring inspections. A monitoring program has been outlined to insure project effectiveness. Invasive species such as Himalayan blackberry, reed canary grass, Japanese knotweed, and English Ivy may invade the restoration zone. These species are stubborn competitors for light and nutrients and limit success of native plants. Invasive species should be removed from the restoration zone should they invade. Herbicides should not be used to achieve this due to the proximity to the wetland. Persistent cutting during the growing season is sufficient to offset the rhizomes of invasive species if they become a problem. Best Management Practices Recommended Best Management Practices for this project are as follows: • Perform excavation and site preparation work during dry weather. • Minimize amount of erodible soils at any given time to the maximum extent feasible. • Check all equipment daily for leaks. Refueling and lubrication of equipment should occur off site. Do not store any fuel, lubricants, chemicals, or hazardous substances outside overnight within the project area. • Do not apply any chemicals when there is a possibility of rain. • Comply with all permits and requirements of governing authority. MONITORING Monitoring of the site will begin the first fall following restoration and maintained on a seasonal basis. The information gathered will provide the following: 1) condition of reintroduced plant species; 2) the use of the site by wildlife species; 3) any unforeseen disturbance and its effect on the protected zones and associated aquatic habitat; 4) any occurrence of exotic species within the wetland or associated buffer; 5) any corrective measures that may be deemed necessary to provide desired conditions. This monitoring will be in effect for the duration of three years. The information gathered will be provided in an annual report and submitted to the Director of Mason County Department of Community Development.

Given the surrounding land use, a Moderate Impact Buffer of I I0-feet with an additional 15-foot building setback has been assigned to this wetland. See Figure 2. Site Map for the approximate wetland and associated buffer location within the property. A restoration plan is included in this report to address two activities: 1) The landscape topography modification and rock quarry installation within an area occupying approximately 1000 square feet within the portion of the wetland and buffer. Restoration entails removing the installed rock, restoring the slope to the gradient continuous with surrounding topography, backfilling the excavated ditches, and planting the entire restoration zone with native trees and shrubs. 2) The removal of four trees within the wetland buffer and three trees within the wetland boundary. Restoration entails replacing the trees at a replacement ratio of 6:1. Therefore, 24 trees will be planted throughout the wetland buffer and 18 trees will be planted throughout the wetland. Best Management Practices have been identified to avoid, minimize, and mitigate for impacts associated with the proposed project. No impacts to water quality or habitat are predicted.

NOTES: Revised 4/97 APPENDIX B Soil Survey Text EVERETT SERIES The Everett series consists of somewhat excessively drained, pale-brown gravelly soils. They occur as inextensive gravel ridges on the glacial moraines or, more commonly, as fairly continuous outwash channels between ridges of Alderwood soils. They have developed upon assorted glacial till and outwash material. The rainfall is 45 to 60 inches a year. The vegetation is mainly drought-resistant madrone, manzanita, and kinnikinnick. Everett soils are droughty because the loose gravel and sandy subsoil and substratum offer little resistance to downward movement of water. The capacity of the surface soil to hold available moisture is low. Everett soils are in the eastern half of the county, in association with the Alderwood soils. They also occur in intricate patterns with the Kitsap and Indianola soils. Compared to the Grove soils, the Everett soils have a paler surface soil and subsoil and, in development, were dominated more by acid igneous parent rock. Everett gravelly sandy loam, 5 to 15 percent slopes (Eh).-This is the most extensive Everett soil. In undisturbed forests 1 to 2 inches of very dark grayish-brown material, a mixture of needles, leaves, twigs, cones, moss, and roots, covers the surface. The surface soil is loose, single-grained, pale-brown, gravelly sandy loam, 6 to 8 inches thick. The upper 2 or 3 inches normally contains aggregates that are slightly hard and redder than the others in the layer. To depths ranging from 18 to 24 inches, the subsoil is loose, singlegrained, light yellowish-brown gravelly sandy loam or gravelly loamy sand. The amount of shot decreases with depth; in the lower part only a few shot occur. The subsoil grades to a substratum of poorly assorted. predominantly yellowish-brown sand, gravel, and cobbly material that is extremely loose and porous. However, in places, this material will stand in banks. The color of this material is largely determined by the gavel, coarse sand, and cobbles, which are olive gray, pale olive, yellowish brown, light brownish gray, gray, and dark gray. Many of the cobbles, as well as much of the gravel, are faintly to moderately stained by iron. The amount of gravel ranges from about 20 percent to 50 percent in the subsoil to as much as 80 percent in the substratum. The soil is medium to strongly acid and becomes less acid with depth. Use and suitability.-This soil is too droughty for most tilled crops--it dries out before crops mature. Only a very small acreage is cultivated, and this is ordinarily farmed along with better adjacent soils. Most of this soil is in brush and trees, for which it is suited best. It is one of the better soils for growing Douglasfirs that are cut for Christmas trees. This is an important use of the soil; large acreages are used for Christmas trees. This soil is in capability subclass VIs and in site class 4 for Douglas-fir.

Wetland Type Wetland Class Estuarine De ressional Natural Heritage Wetland Riverine Bog Lake-fringe Mature Forest Sloe X Old Growth Forest Flats Coastal Lagoon Freshwater Tidal Interdunal None of the above X Does the wetland being rated meet any of the criteria below? If you answer YES to any of the questions below you will need to protect the wetland according to the regulations regarding the special characteristics found in the wetland. Check List for Wetlands that Need Special Protection, YES NO and That are Not Included in the Rating SP 1. Has the wetland been documented as a habitat for any Federally listed Threatened or Endangered plant or animal species (TIE species)? For the purposes of this rating system,"documented" means the wetland is on the appropriate X state or federal database. SP2. Has the wetland been documented as habitat for any State listed Threatened or Endangered X plant or animal species? For the purposes of this rating system, "documented" means the wetland is on the appropriate state database. SP3. Does the wetland contain individuals of Priority species listed by the WDFW or the state? X SP4. Does the wetland have a local significance in addition to its functions? For example, the X wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next part of the data sheet you will need to determine the Hydrogeomorphic Class of the wetland being rated. The hydrogeomorphic classification groups wetlands in to those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form—western Washington(11/04) Pagel of 8 Classification of Vegetated Wetlands for Western Washington Wetland Name: 8830 E Highway 106 Date: 4/16/10 1. Are the water levels in the wetland usually controlled by tides (i.e. except during floods)? NO—go to 2 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 forms for Riverine wetlands. If it is a Saltwater Tidal Fringe it is rated as an Estuarine wetland. Wetlands that were call estuarine in the first 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. Is the topography within the wetland flat and precipitation is only source (>90%) of water to it. NO—go to 3 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 wetland meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of open water(without any vegetation on the surface) where at least 20 acres (8ha)are permanently inundated(ponded or flooded); At least 30%of the open water area is deeper than 6.6 (2 m)? NO—go to 4 YES—The wetland class is Lake-fringe(Lacustrine Fringe) 4. Does the wetland meet all of the following criteria? x The wetland is on a slope (slope can be very gradual). x 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. x The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these types of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 foot deep). NO—go to 5 YES—The wetland class is Slope 5. Is the wetland in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river? The flooding should occur at least once every two years, on the average, to answer"yes". The wetland can contain depressions that are filled with water when the river is not flooding. NO—go to 6 YES—The wetland class is Riverine 6. Is the wetland in a topographic depression in which water ponds, or is saturated to the surface, at some time of the year. This means that any outlet, if present is higher than the interior of the wetland. NO—go to 7 YES—The wetland class is Depressional 7. Is the wetland located in a very flat area with no obvious depressional and no stream or river running through it and providing water. The wetland 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 seems to be difficult to classify. 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. Sometimes we find characteristics of several different hydrogeomorphic classes within one wetland boundary. 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 10% or more of the total area of the wetland being rated. If the area of the second class is less than 10%classify the wetland using the first class. HGM Classes Within a Delineated Wetland Boundary Class to Use in Rating Slope+Riverine Riverine Slope+Depressional Depress onal Slope+Lake-fringe Lake-fringe Depressional+Riverine along stream within boundary Depressional Depressional + Lake-fringe Depressional Salt Water Tidal Fringe and any other class of Treat as ESTUARINE under wetlands with special freshwater wetland characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Aspen Stands: Pure or mixed stands of aspen greater than 0.8 ha(2 acres) Cliffs: Greater than 7.6m(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 multi-layered canopy with occasional small openings,with at least 20 trees/ha(8 trees/acre)>81cm (32 in)dbh or>200 years of age. X Mature forests: Stands with average diameters exceeding 53cm(21 in)dbh;crown cover may be less than 100%; decay,decadence,numbers of snags, and quantity of large downed material is generally less than that found in old-growth; 80—200 years old west of the Cascade Crest. Prairies: Relatively undisturbed areas(as indicated by dominance of native plants)where greases and/or forbs form the natural climax plant community. Talus: Homogenous areas of rock rubble ranging in average size 0.15—2.Om(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 occurring cavity, recess, void, or system of interconnected passages. Oregon white Oak: Woodlands stands of pure oak or oak/conifer associations where canopy 3 coverage of the oak component of the stand is 25%. 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 of natural 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 habitat extends upstream and landward to where ocean-derived salts measure less than 0.5 ppt.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 of the 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).

Wetland Type— Check off any criteria that apply to the wetland. Circle the Category when the appropriate criteria are met. SC1 Estuarine wetlands.? (see p.87) Does the wetland meet the following criteria for Estuarine wetlands? The dominant water regime is tidal, Vegetated, and With a salinity greater than 0.5 ppt. YES =Go to SC 1.1 NO X SC 1.1 Is the wetland within a National Wildlife Refuge,National Park, National Estuary Reserve, Natural Area Preserve, State Park or Educational, Environmental, or Scientific Reserve designated under WAC 332- 30-151? Cat. I YES =Category I NO=go to SC 1.2 SC 1.2 Is the wetland at least I acre in size and meets at least two of the following conditions? YES =Category I NO=Category II Cat. I The wetland is relatively undisturbed (has no diking, ditching, filling, cultivation, grazing, and has less than 10%cover of non-native plant species. If the non-native Spartina spp_ are only species that cover more than 10%of the wetland, then the wetland should be given a dual rating(I/II). Cat. II The area of Spartina would be rated a Category 11 while the relatively undisturbed upper marsh with native species would be a Category I. Do not, however, exclude the area of Spartina in determining the size threshold of l acre. Dual At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest, or un-grazed Rating or un-mowed grassland I/II The wetland has at least 2 of the following features: tidal channels, depressions with open water, or contiguous freshwater wetlands. SC2 Natural Heritage Wetlands (seep. 88) Natural Heritage wetlands have been identified by the Washington Natural heritage Program/DNR as either high quality undisturbed wetlands or wetlands that support state Threatened, Endangered, or Sensitive plant species. SC 2.1 Is the wetland being rated in a Section/Township/Range that contains a natural heritage wetland? (This question is used to screen out most sites before you need to contact WNNP/DNR.) S/T/R information from Appendix D or accessed from WNHP/DNR web site YES Contact WNHP/DNR(see p. 88)and go to SC 2.2 NO X SC 2.2 Has DNR identified the wetland as a high quality undisturbed wetland or as a site with state threatened or endangered plant species? Cat I YES =Category 1 NO X SC3 Bogs (see p. 88) Does the wetland (or part of the wetland) meet both the criteria for soils and vegetation in bogs? Use the key below to identify if the wetland is a bog. If you answer yes you will still need to rate the wetland based on its function. 1. Does the wetland have organic soil horizons (i.e. layers of organic soil), either peats or mucks, that compose 16 inches or more of the first 32 inches of soil profile? (See Appendix B for a field key to identify organic soils)? YES=go to question 3 NO=go to question 2 2. Does the wetland have organic soils, either peats or mucks that are less than 16 inches deep over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on a lake or pond? YES=go to question 3 NO= is not a bog for purpose of rating 3. Does the wetland have more than 70%cover of mosses at ground level, AND other plants, if present, consist of the"bog"species listed in Table 3 as a significant component of the vegetation (more than 30%of the total shrub and herbaceous cover consists of species in Table 3)? YES= Is a bog for purpose of rating NO=go to question 4 NOTE: If you are uncertain about the extent of mosses in the understory you may substitute that criterion by measuring the pH of the water that seeps into a hold dug at least 16"deep. If the pH is less than 5.0 and the "bog" plant species in Table 3 are present, the wetland is a bog. 4. Is the wetland forested (>30%cover) with sitka spruce, subalpine fir, western red cedar, western hemlock, lodgepole pine,quaking aspen, Englemann's spruce, or western white pine. WITH any of the species(or combination of species) on the bog species plant list in Table 3 as a significant component of the ground cover (> 30%coverage of the total shrub/herbaceous cover)? Cat. I YES=Category I NO= Is not a bog for purpose of rating Wetland Rating Form—western Washington(11/04) Page 7 of 8 C4 Forested Wetlands (seep. 96) Does the wetland have at least 1 acre of forest that meet one of these criteria for the Department of Fish and Wildlife's forests as priority habitats?. 1f you answer yes you will still need to rate the wetland based on its function. Old-growth forests: (west of Cascade Crest) Stands of at least two three species forming a multi-layered canopy with occasional small openings; with at least 8 trees/acre(20 trees/hectare) that are at least 200 years of age OR have a diameter at breast height(dbh) of 32 inches (81 cm or more). NOTE: The criterion for dbh is based on measurements for upland forests. Two-hundred year old trees in wetlands will often have a smaller dbh because their growth rates are often slower. The DFW criterion is and "OR" so old-growth forests do not necessarily have to have trees of this diameter. Mature forests: (west of the Cascade Crest) Stands where the largest trees are 80 —200 years old OR have an average diameters (dbh) exceeding 21 inches (53 cm); crown cover may be less than 100%; decay, decadence, numbers of snags, and quantity of large downed material is generally less than that found in old-growth.
