The delineation was performed on October 8th, 2013 to identify wetlands and associated buffers that would be applicable to future use of the site. The subject property is located in the SE '/4 of Section 24, Township 22 North, Range 02 West WM (Figure 1 Vicinity Map). According to the Mason County Assessor, both parcels are 5.0 acres in size. For the purposes of federal, Washington State, and Mason County jurisdictional oversight, this wetland delineation followed the methodology outlined in the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0) U.S. Army Corps of Engineers May 2010. WAC 173-22-035 states delineations should be done according to this manual and supplements. The changes became effective March 14, 2011. 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 Parcel 2224-76-00080 is adjacent to the north of parcel 22224-76-00090. The properties are accessed via East Rasor Road and its intersection with East Chelsea Lane. East Chelsea Lane makes up the eastern property boundary of both parcels. East Rasor Road crosses east/westerly through parcel 22224-76-00080. The parcels are surrounded by residential parcels of varying size and shape. The property contains no permanent buildings or structures. Topography throughout both properties is generally flat, with the exception of a low gradient slope down toward a depressional wetland area located within the northern portion of parcel 22224-76-00090, within 100 feet of parcel 2224-76-00080. The property contains both forested areas and shrub dominated areas. Upland areas consist of a forested community generally consisting of Douglas fir (Pseudotsuga menziesii, FACU) with an understory of salal (Gaultheria shallon, FACU), swordfern (Polystichum munitum, FACU) and evergreen huckleberry (Vaccinium ovatum, FACU).

Details regarding the wetland characteristics are discussed throughout this wetland evaluation. METHODOLOGY Consistent with procedures detailed in the Washington State Wetlands Identification and Delineation Manual (Washington State Department of Ecology, 2011) (2011 Manual), preliminary information was gathered on the project site prior to the field review and delineation. General information sources included: 1974 United States Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) maps, the Soil Survey of Mason County Area, Washington (USDA, 1951), the Washington Department of Natural Resources Water Resource Map, and Mason County's critical areas regulations. Field Delineation The methodology used for this wetland delineation was consistent with the technical approaches articulated in the 2011 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 October 5th, 2013. Field work was conducted under sunny conditions with temperature ranging between 55 and 60 degrees Fahrenheit. The time of year and recent precipitation history were considered in assessing the extent of the suspect wetlands 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 two sample plot locations. Each sample plot included a data form completed for a wetland area and a form completed for the corresponding upland area. Data collected at each sample plot was entered onto a PO Box 2854 Belfair,Washington 98528-Cell Phone 360-620-0618.Office Phone 360-372-2421-wetlandcorps@hotmail.com Parcel 22224-76-00080 and 22224-76-00090 Wetland Delineation TWC No.13WO25 October 2013 Page No.3 Routine Wetland Determination Data Form (USACOE Western Mountains, Valleys, and Coast-Version 2.0). BACKGROUND INFORMATION Mason County Soil Survey The soil survey of Mason County indicates one onsite soil type (USDA, 1951): The onsite soil type is identified as: Alderwood gravelly sandy loam, 5 to 15 percent slopes (Ab).-This is the most extensive, soil of the Alderwood series. The Alderwood series consists of brown, well-drained, upland soils. They have developed from mixed gravelly glacial till dominated by acid igneous rock. The imbedded gravel is mainly granite and quartzite. Rainfall is 45 to 60 inches a year. The native vegetation is a dense forest consisting almost entirely of Douglas-fir and a dense understory of salal, Oregon-grape, vine maple, and huckleberry. Northeast of the Hood Canal the understory is mainly rhododendron. Alderwood soils occupy the extensive rolling glacial moraines, and they are the dominant soils in the eastern part of the county. The Alderwood soils are associated with the somewhat excessively drained Everett and Indianola soils and with the moderately well drained Kitsap soils. Shelton and Hoodsport soils differ from the Alderwood soils in that they have developed under high rainfall and from glacial till having a much higher content of basic igneous rock. The Shelton and Hoodsport soils are more reddish throughout the profile. The Shelton soils are usually deeper to the cemented till than the Alderwood soils. 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 vicinity of the subject parcel. The nearest mapped wetland shown by NWI is a small, isolated wetland mapped approximately 0.5 mile west of the subject property. DNR Water Resources Man The Department of Natural Resources Water Resources Map shows a stream draining northerly within 200 feet northwest of the subject property (see Figure 5. WA DNR Water Resources Map). The tributary is mapped as a type "N" (nonfishbearing channel). During the field visit, no streams were identified within or within proximity to the identified wetland.

Spirea(Spiraea douglasii,FACW)dominates the scrub-shrub wetland community. WETLAND DELINEATION RESULTS One isolated wetland was identified within the northern portion of parcel 22224-76-00080 and terminating in the central portion of parcel 22224-76-00090. The wetland is within 100 feet of parcel 22224-76-00090. The wetland is characterized by a shrub scrub community of willows and spirea. The wetland occupies a total area of approximately one half acre. The wetland is delineated in the field with orange ribbon. The wetland is a groundwater receptor wetland, meaning it is located in the lowest point in general topography and receives hydrology primarily from surface runoff and a high water table. The wetland contains no channelized surface water outlet. During flood events, surface water likely drains easterly from the wetland as sheetflow. The wetland boundary was identified primarily by the abrupt transition from upland vegetation such as salal (Gaultheria shallon, FACU) and swordfern (Polystichum munitum, FACU) to facultative wetland vegetation, primarily spirea (Spiraea douglasii, FACW) and willows (Salix sp., FAQ. The presence of facultative wetland vegetation in congruence with topography patterns and positive wetland hydrology indicators was used to identify the wetland boundary. Vegetation The wetland contains an overstory of scouler willow (Salix scouleriana, FAQ, Pacific willow (Salix lucida, FACW), cascara (Rhamnus purshiana, FAQ, and red alder (Alnus PO Box 2854 Belfair,Washington 98528•Cell Phone 360-620-0618.Office Phone 360-372-2421•wetlandcorps@hotmail.com Parcel 22224-76-00080 and 22224-76-00090 Wetland Delineation TWC No.13W025 October 2013 Page No.5 rubra, FAC). The shrub layer consists of spirea (Spiraea douglasii, FACW), with an herbaceous community of slough sedge (Carex obnupta, OBL) . Wetland vegetation is indicated by hydrophytic vegetation FAC and FACW dominating over 50 percent of the vegetation community in wetland data plots. The upland vegetation adjacent to the wetland area is comprised of Douglas fir (Pseudotsuga menziesii, FACU), saW (Gaultheria shallon, FACU), evergreen huckleberry (Vaccinium ovatum, FACU), brackenfern (Pteridium aquilinum, FACU) and swordfern (Polystichum munitum, FACU) with lesser amounts of Oregon grape (Mahonia nervosa, UPL). Hydophytic vegetation occupies less than 50 percent of the vegetative community in upland data plots. Soils The profiles within the test pits consisted of a single layer profile consisting of silt loam to 12 inches deep with matrix chroma 10YR 3/1 and IOYR 2/1. Wetland hydric soils are indicated by a thick, dark, surface on the surface of the soil and the presence of muck within the loamy mineral soil. In addition, the soil consists of a low-chroma (equaling one) in all wetland test pits. The soil profiles observed in known upland test pits exhibited a two-layer soil profile. The upper layer consists of gravelly sandy loam approximately eight to ten inches deep of matrix chroma 1 OYR 3/3. The lower profile contained less gravel with a matrix chroma of 1 OYR 6/3. No hydric soil indicators were present in upland soil test pits. Hydrology Wetland hydrology is indicated by FAC-neutral vegetation, drainage patterns, and water stained leaves. Approximately 30% of the wetland was inundated on the day of the field visit, up to six inches in some areas. In addition, the sample plots within the wetland area revealed free water in the test pits at a two inch depth and soil saturation to the surface. Upland test pits showed no indicators of wetland hydrology. WETLAND EVALUATION The wetland is classified as a Depressional wetland per Washington State Wetland Rating System for Western Washington (Hruby 2004). Based on functional attributes associated with the wetland including habitat, water quality, and hydrology functions, it has been rated as a Category III wetland, scoring 32 points on the state rating form. The score for water quality functions in this wetland is 12, hydrological functions scored 7, and the score for habitat functions is 13 (see Appendix C for rating form). According to Table 17.01.070 D of the Mason County Resource Ordinance, the base buffer width for Category III Wetlands scoring less than 20 points in habitat function is 60 feet with an additional 15- foot building setback within parcels intended for Moderate Impact Land Use.

This buffer extends onto both parcel 22224-76-00090 and 22224-7600080. SUMMARY This wetland report documents the presence of a Category III Wetland with low habitat function located within the northern portion of parcel 22224-76-00090, within 100 feet of the southern boundary of parcel 22224-76-00080. Category III Wetlands with low habitat function in Mason County require a 60 foot buffer with an additional 15-foot building setback in Mason County for Moderate Impact Land Use. This buffer extends onto both parcels. We trust this information is sufficient for you at this time. Thank you for choosing the Wetland Corps as your environmental consultant.

They have developed from mixed gravelly glacial till dominated by acid igneous rock. The imbedded gravel is mainly granite and quartzite. Rainfall is 45 to 60 inches a year. The native vegetation is a dense forest consisting almost entirely of Douglas-fir and a dense understory of salal, Oregon-grape, vine maple, and huckleberry. Northeast of the Hood Canal the understory is mainly rhododendron. Alderwood soils occupy the extensive rolling glacial moraines, and they are the dominant soils in the eastern part of the county. The Alderwood soils are associated with the somewhat excessively drained Everett and Indianola soils and with the moderately well drained Kitsap soils. Shelton and Hoodsport soils differ from the Alderwood soils in that they have developed under high rainfall and from glacial till having a much higher content of basic igneous rock. The Shelton and Hoodsport soils are more reddish throughout the profile. The Shelton soils are usually deeper to the cemented till than the Alderwood soils. Alderwood gravelly sandy loam, 5 to 15 percent slopes (Ab).-This is the most extensive, soil of the Alderwood series. It occupies undulating to rolling moraines. In undisturbed areas a 1- to 2-inch mat of very dark brown, acid organic matter is on the surface. This grades to a thin, dark grayish-brown, highly organic mineral soil. The surface soil consists of a friable, brown, medium acid gravelly sandy loam 8 to 13 inches deep. It has a weak granular structure and contains numerous rounded shot. Below the surface soil, to depths ranging from 18 to 24 inches, is a pale-brown gravelly sandy loam that is very friable, is single grained; and contains small to moderate amounts of shot . Between this layer and the cemented till is a 3- to 10-inch layer of very pale brown gravelly sandy loam. It contains no shot and is firmer but has the same texture as the layer above. However, it is faintly to distinctly spotted and horizontally streaked with brown and yellow. The cemented till consists of light-gray, gravelly sandy loam, and it normally occurs at depths ranging from 24 to 32 inches. It is impermeable to roots and very slowly permeable to water. The first few inches is usually laminated and streaked with reddish brown and yellow. Below this, to a depth of many feet, the till is uniformly cemented, fairly uniform light gray, and medium to strongly acid. A thin mat of roots often lies over the till. The cemented substratum tends to restrict the rapid downward movement of moisture. Use and suitability.-Not more than about 5 percent of this soil has been cleared and is used for crops or pasture. Most of the cultivated acreage is near the inlets of Puget Sound in the vicinities of Arcadia and Allyn. In this area the Alderwood soils are associated with the better agricultural soils of the Cloquallum, Sinclair and Kitsap series. Hay, small grains, pasture, fruits, nuts, grapes, and berries are the principal crops grown on the Alderwood soils. The lack of subsoil moisture damages crops in summer. For this reason, early maturing, short-season crops are suited best to this soil. Yields of all crops are usually fairly low because of low fertility and the dry summers. Pastures produce good forage in spring and late in fall if proper plants are used and management is good. The deeper soils are suited best to fruits, nuts, and grapes. The uncleared and remote areas are better suited to forestry than to cultivated crops. Nearly all the uncleared acreage is in second-growth forest 70 to 80 years of age. Shallowness to the compact till often inhibits growth of the older trees. The soil, however, is well suited to production of Christmas trees. Douglas-fir readily restocks in thick stands containing trees of good form. Stands of small trees are often thinned and pruned to maintain good form of growth. The growing of Christmas trees has expanded rapidly in the past few years and is now one of the important industries in the county. It is one of the proper uses of the cutover lands that are not in a high site class. Alder-wood soils need barnyard manure, green manure, nitrogen, or legumes to maintain a fertility for crop production. Phosphate fertilizers and green manure or barnyard manure greatly improve fertility. Nitrogen fertilizer is often applied with barnyard manure or when cover crops are plowed under. The fertilizer furnishes additional nitrogen needed to hasten decay of the organic matter. This soil is in capability subclass Vls and in site classes 4 and 5 for Douglas-fir. Small areas along- the border, where the soil is more than 32inches deep to compact till, are in site classes 3 and 4 for Douglas-fir.

Has the wetland unit been documented as a habitat for any Federally listed Threatened or Endangered animal or plant species (TIE species)? ❑ For the purposes of this rating system,"documented" means the wetland is on the appropriate state or federal database. SP2. Has the wetland unit been documented as habitat for any State listed Threatened or Endangered animal species? For the purposes of this rating system, "documented" means the ❑ wetland is on the appropriate state database. Note: Wetlands with State listed plant species are categorized as Category 1 Natural Heritage Wetlands(see p. 19 of data form). SP3. Does the wetland unit contain individuals of Priority species listed by the WDFW or the state? ❑ SP4. Does the wetland unit have a local significance in addition to its functions? For example,the 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 Hydrop-eomorphic Class of the wetland beine rated. The hydrogeornotphic classif Gabon groups wetlands in to those that fimc ion in similar ways. This simplifies the questions needed to arimmr how well the wetland fiaclions. The Hyd mgeommphic Class ofa wetland can be determined using the key below. See p.24 for more detailed irmuctions on classifying wedands. Wetland Rating Form—Western Washington,Version 2(7/06),updated with new WDFW definitions Oct.2008 Page l of 12 Wetland name or number Classification of Vegetated Wetlands for Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated,you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply,and go to Question 8. 1. Are the water levels in the entire unit 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) Ifyour 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 fast 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 11 estuarine wetlands have changed(see p. ). 2. The entire wetland unit is flat and precipitation is only source (>90%)of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. ®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 entire wetland 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) where at least 20 acres (8ha) in size; ❑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 entire wetland 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? 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. Does the entire wetland meet all of the following criteria? ❑ The unit is in a valley or stream channel where it gets inundated by overbank flooding from that stream or river. ❑ The overbank flooding occurs at least once every two years. NOTE: The riverine unit 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 entire wetland unit 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 entire wetland 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 classes. 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 HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT(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 10%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 10%of the unit,classify the wetland using the class that represents more than 90%of the total area Slope +Riverine Riverine Slope+ Depressional Depressional.

(see p.86) Does the wetland unit 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 SC 1.1 Is the wetland unit within a National Wildlife Refuge,National Park,National Estuary Reserve,Natural Cat. 1 Area Preserve, State Park or Educational,Environmental, or Scientific Reserve designated under WAC ❑ 332-30-151? ❑YES =Category I ® NO=go to SC 1.2 SC 1.2 Is the wetland at least 1 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 sp ,. are only species Cat. 11 that cover more than 10%of the wetland,then the wetland should be given a dual rating(I/II). ❑ The area of Spartina would be rated a Category 1I while the relatively undisturbed upper marsh with native species would be a Category 1. Do not,however,exclude the area of Spartina in Dual determining the size threshold of 1 acre. ❑ At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub,forest, or un-grazed or Rating un-mowed grassland 1/11 ❑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. 87) 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 WNHP/DNR.) ® S/T/R information from Appendix D ®or accessed from WNHP/DNR web site ❑YES Contact WNHP/DNR(see p.79)and go to SC 2.2 ® NO SC 2.2 Has DNR identified the wetland as a high quality undisturbed wetland or as a site with state threatened Cat I or endangered plant species? ❑YES =Category 1 ® NO not a Heritage Wetland ❑ C3 Boas(seep. 87) Does the wetland(or any part of the unit)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 unit 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 unit 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 hole 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 unit 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,Version 2(7/06),updated with new WDFW definitions Oct.2008 Page 1 I of 12 Wetland name or number C4 Forested Wetlands (seep. 90) 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? If 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. Cat.I ❑YES=Category I ® NO=not a forested wetland with special characteristics ❑ SC5 Wetlands in Coastal Lagoons (seep. 91) Does the wetland meet all of the following criteria of a wetland in a coastal lagoon? 3 ❑The wetland lies in a depression adjacent to marine waters that is wholly or partially separated from . marine waters by sandbanks,gravel banks, shingle,or, less frequently,rocks. , ❑ The lagoon in which the wetland is located contains surface water that is saline or brackish(>0.5 r ppt)during most of the year in at least a portion of the lagoon (needs to be measured near the bottom.) ❑YES=Go to SC 5.1 ® NO not a wetland in a coastal lagoon SC 5.1 Does the wetland meet all of the following three conditions? ❑ The wetland is relatively undisturbed(has no diking,ditching, filling, cultivation,grazing)and has less than 20%cover of invasive plant species(see list of invasive species on p. 74). ❑ At least 3/4 of the landward edge of the wetland has a 100 ft. buffer of shrub, forest,or un-grazed or Cat. I un-mowed grassland. ❑ ❑ The wetland is larger than 1/10 acre(4350 square ft.) Cat. II ❑YES=Category I ® NO =Category II ❑ SC6 Interdunal Wetlands (seep. 93) Is the wetland west of the 1889 line(also called the Western Boundary of Upland Ownership or WBUO)? ❑YES=Go to SC 6.1 ® NO not an interdunal wetland for rating If you answer yes you will still need to rate the wetland based on its Junctions. In practical terms that means the following geographic areas: • Long Beach Peninsula-- lands west of SR 103 • Grayland-Westport-- lands west of SR 105 • Ocean Shores-Copalis—lands west of SR 115 and SR 109 SC 6.1 Is the wetland one acre or larger,or is it in a mosaic of wetlands that is one acre or larger? Cat. II ❑YES=Category II ® NO =go to SC 6.2 ❑ SC 6.2 Is the wetland between 0.1 and 1 acre,or is it in a mosaic of wetlands that is between 0.1 and 1 acre? Cat. III ❑YES=Category III ❑ Category of wetland based on Special Characteristics ♦ Choose the "highest"rating if wetland falls into several categories, and record on p. 1.
