The park is popular with visitors due to its proximity to the river and the recreational opportunities it provides including camping, picnicking, community gathering, wildlife viewing, fishing, and boating. However,the park's existing 41 campsites are located within the 100-year floodplain of the East Fork Satsop River and annual flooding of the park results in seasonal closures of the campground and damage that requires extensive repair and maintenance. The Schafer State Park Campground Relocation Concept Plan (Concept Plan;J.A.Brennan et al. 2019)was recently developed in an effort to protect park facilities and reduce flooding.The Concept Plan includes a phasing outline,which consists of several phases. 1 .2 Project Overview Based on the Concept Plan,the Washington State Parks and Recreation Commission currently seeks to construct Phase 1 of the project.Phase 1 will expand campground development at a location in the park that will be less susceptible to flooding.Design elements of Phase 1 include: • Welcome center area(without welcome center) • Self-registration kiosk • East campground loop with asphalt and two cabins • Utilities at east campground loop campsites (water and electric) • New entry loop road • Comfort station septic drain field (at east campground) • Cut, fill, and grade preparation for east campground loop • Initial planting for east campground and welcome center areas • Mitigation planting The approximate Phase 1 project area is shown in Figure 1 on the following page. 1 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13, 2020 Campground Relocation Project Phase 1 0- •tr � � s ro Ila des �j L ,i,�� �rt'1�' .•' - fie.' � -x�..",� `'�' fi; - '^ >" W Satsop Cloquallum Rd Figure 1. Approximate Phase 1 project area outlined in red (Google Earth, imagery dated 7/21/2018). 1 .3 Document Purpose Construction of Phase 1 design includes development within environmentally sensitive areas. The purpose of this report is to demonstrate compliance with applicable Mason County codes for such areas. 2 Existing Conditions As part of the development of the Concept Plan,The Watershed Company(2018)prepared a Site Analysis and Program Considerations Technical Memorandum that identified potentially regulated features at Schafer State Park. In December 2019, ecologists from The Watershed Company delineated jurisdictional wetlands and streams that may have regulatory implications for the Phase 1.This effort is documented in the Schafer State Park Wetland and Stream Delineation Report(The Watershed Company 2020),which is provided in Appendix C.The remainder of this section provides a summary description of existing conditions in the Phase 1 project area, including wetlands and streams. 2 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13,2020 Campground Relocation Project Phase 1 2 .1 General Description The Phase 1 project area features existing campground development,including structures, internal roads,and hiking trails. The current official map for the park shown below in Figure 2 provides a basic sketch of the existing campground development in the Phase 1 project area.

Much of the park located to the east of West Schafer Park Road,including much of the Phase 1 project area,has recently been logged due to widespread Douglas-fir root rot infection.This area has been replanted with a variety of conifers, including western red cedar, shore pine, white pine, and Sitka spruce.This area has low canopy coverage due to the recent logging,with some bigleaf maple providing canopy cover. The understory is very diverse and includes snowberry,low Oregon grape,salal,and trailing blackberry. 2 .2 Wetlands Four wetlands(A,B,F and G)are located within the Phase 1 project area. 3 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13, 2020 Campground Relocation Project Phase 1 2.2.1 Wetland A Wetland A is a large riverine wetland that is partially adjacent to the East Fork Satsop River. Wetland A is a Category II wetland with eight habitat points.The western extent of the wetland that is not immediately adjacent to the river is marked by a berm/earthen dam,which acts as a hydrologic barrier that disconnects Wetlands A and B.Wetland A features a shrub stratum including red osier dogwood and salmonberry. Invasive species,including reed canarygrass and Himalayan blackberry, are also present(Figures 3 and 4).A tree stratum is not present. Areas around Wetland A and along the adjacent trail are dominated by a bigleaf maple canopy and a snowberry, salmonberry,vine maple, and sword fern understory. i:T r : o .1 •E, . •T — ,�`_ yyy 7 e j P f ri l,•;: ,t� �°:' r,;�:� � 1.;� ps� � .'.-•�, ''�' 'j�,��.

Wetland B is a Category III wetland with seven habitat points. Wetland B features a shrub stratum including red osier dogwood and salmonberry.Invasive species,including reed canarygrass, are also present.A tree stratum is not present.Outside of wetlands,the swale/depression is vegetated with salmonberry, snowberry, and sword fern. Adjacent upslope areas are dominated by a bigleaf maple canopy with a sword fern, salal, and snowberry understory. 2.2.3 Wetland F Wetland F is a small depressional wetland situated along the swale that runs through the eastern portion of the park.Wetland F is a Category II wetland with seven habitat points.

Photo taken December 5, 2019. 2 .3 Streams The East Fork Satsop River runs along the eastern portion of the Phase 1 project area. Wetlands A and B extend along much of the river's shoreline located in the Phase 1 project area. 3 Local Regulations Mason County regulations applicable to environmentally sensitive areas include the Shoreline Master Program(SMP) and the Mason County Resource Ordinance. Areas of the Phase 1 project area that fall under jurisdiction of the SMP include uplands within 200 feet of the ordinary high water mark(OHWM) of the East Fork Satsop River,as well as shoreline-associated wetlands.All wetlands delineated in the Phase 1 project area(Wetlands A, B,F, and G)represent shoreline-associated wetlands.Wetlands A and B are located with 200 feet of the OHWM of the East Fork Satsop River.Wetlands F and G,while located beyond 200 feet of the OHWM of the East Fork Satsop River, are within its adjacent 100-year floodplain and are therefore shoreline-associated.Wetland buffers located beyond 200 feet of the OHWM of the East Fork Satsop River are not included in Mason County's shoreline jurisdiction. 7 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13,2020 Campground Relocation Project Phase 1 3.1 Wetlands Mason County requires a standard 225-foot buffer for Category II wetlands with high habitat scores (8-9) and a standard buffer of 110 feet for Category II wetlands with moderate habitat scores (5-7).Therefore,Wetland A has a standard buffer of 225 feet, and Wetlands B,F and G have standard buffers of 110 feet. A structure setback of 15 feet from wetland buffers is also required. 3 .2 Streams The East Fork Satsop River has a 150-foot standard buffer. A structure setback of 15 feet from stream buffers is also required. 4 Proposed Conditions 4.1 Impacts Plans showing the proposed project impacts to wetland and stream buffer areas are included in Appendix A. 4.1.1 Impact Avoidance & Minimization Pursuant to Mason County code,the project is required to follow mitigation sequencing.The project avoids direct impacts to wetlands and streams.While the design team has sought to avoid impacts to buffer areas, complete avoidance of buffer areas is not feasible given their extensive encumbrance of the Phase 1 project area and the infrastructure needed for a viable project. The design team has sought to minimize buffer impacts by siting the proposed development within areas of existing disturbance and limiting new impacts to the extent feasible.In the combined shoreline and Wetland A and B buffer,an existing internal road runs generally parallel to the shoreline on the west side of Wetlands A and B. Except for a trail along the shoreline, this road represents the easternmost extent of the existing campground development in the Phase 1 project area.The proposed project generally does not propose development waterward of this existing road(which will be removed as part of the project). In the buffer of Wetland G,proposed development would be oriented around an existing internal road that bisects the buffer.Further,most proposed development in the buffer of Wetland G would occur on the other side of the road from the wetland. In the buffer of Wetland F,the proposed development would be oriented around an existing trail that bisects the buffer.The proposed loop drive alignment through the buffer of Wetland F is needed to provide sufficient turning 8 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13, 2020 Campground Relocation Project Phase 1 radii for recreational vehicles and vehicular access to an existing septic tank located in the buffer.Moreover,the alignment of the loop drive routes vehicles away from staff housing and maintenance areas. Impacts to wetland hydroperiods are not anticipated from proposed development.The site design utilizes existing grades and existing areas of development to the extent feasible. Stormwater will sheet flow from proposed surfaces to infiltrate into nearby native soils and natural areas.Therefore,hydrologic patterns and associated wetland hydroperiods are not expected to significantly change from existing conditions. 4.1.2 Impact Assessment The proposed project will impact wetland and stream buffer areas. In total,33,812 square feet of permanent buffer impacts are proposed.Virtually all these impacts would occur in wetland buffers,with only very limited impacts occurring within the 150-foot standard river buffer. Permanent buffer impacts broken out by impact area, and the overall impact area, are shown below in Table 1. Table 1. Permanent buffer impacts. Impact Area Permanent Impact Combined shoreline and 23,970 SF Wetland A and B buffer Wetland G buffer 6,455 SF Wetland F buffer 3,387 SF Total 33,812 SF In addition to permanent buffer impacts, 18,685 square feet of temporary buffer impacts are anticipated.The temporary impacts represent areas that would be disturbed to construct the project,but that would not feature permanent campground infrastructure. 4. 2 Mitigation To compensate for impacts, State Parks has prepared Mitigation Planting plans (see Appendix B). The plans propose mitigation at three locations in the Phase 1 project area. Mitigation Area 1 is located in the eastern portion of the combined shoreline and Wetland A and B buffer.Situated immediately adjacent to the East Fork Satsop River,Mitigation Area 1 offers a high-value location for mitigation.The extent of existing native vegetation varies in Mitigation Area 1.Accordingly,under the Mitigation Planting plans,the southern part of Mitigation Area 1 (designated Area 1a in the plans)will be more fully planted with a diverse 9 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13,2020 Campground Relocation Project Phase 1 assemblage of native species. The northern part of Mitigation Area 1 (designated as Area 1b in the plans)will be planted with infill plantings including trees and shrubs. Several of the plantings proposed for Mitigation Area 1 will be planted within Wetlands A and B (Figure 7). Mitigation Area 1 consists entirely of enhancement.Long-term changes to Mitigation Area 1 (as well as Mitigation Areas 2 and 3,below)from enhancement activities are anticipated to include a reduction of invasive plant species, an increase in native species cover and diversity, and an increase in tree quantities and associated forested conditions. --r _ z Figure 7. View of reed canarygrass dominant portion of Wetland A adjacent to the East Fork Satsop River proposed for enhancement. Photo taken October 26, 2018. Mitigation Area 2 consists of areas of the Wetland G buffer that will be undeveloped after project construction.These areas will be planted with infill plantings including native trees and shrubs.Mitigation Area 2 generally consists of enhancement;however, some mitigation consists of restoration, as in some locations existing infrastructure will be removed before being planted. Mitigation Area 3 consists of areas of the Wetland F buffer that will be undeveloped after project construction,excluding areas of lawn maintained in proximity to existing structures. These areas will be planted with infill plantings including native trees and shrubs. The vegetation that will be planted on the south side of the loop drive, primarily western hemlock and beaked hazelnut, in addition to providing ecological functions,will also serve to screen the existing nearby staff housing. Mitigation Area 3 consists almost entirely of enhancement. 10 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13,2020 Campground Relocation Project Phase 1 The mitigation area within each impact area, as well as the overall mitigation area, are shown below in Table 2. Table 2. Mitigation areas. Impact Area Mitigation Area Combined shoreline 33,550 SF and Wetland A and B (Mitigation Area 1a-full) buffer --------------------------------------- 25,378 SF (Mitigation Area 1b-infill) 60,928 SF -- — --------- (Mitigation Area 1-full/infill) Wetland G buffer 37,353 SF (Mitigation Area 2-infill) Wetland F buffer 20,643 SF (Mitigation Area 3-infill) Total 119,924 SF In general,projects with buffer impacts typically provide mitigation at a 1:1 ratio.However,for this project,because the Mitigation Planting plans propose extensive infill planting, except for Mitigation Area la, the plans provide mitigation for buffer impacts in exceedance of the typical 1:1 ratio. Table 3 below indicates the ratio of mitigation to impacts for each impact area, as well as overall. For the combined shoreline and Wetland A and B buffer, the proposed mitigation compensates for impacts at a ratio of greater than 2:1. Notably,the 33,550 square feet of full planting in Mitigation Area 1a will more than offset the 23,970 square feet of impacts at a 1:1 ratio. However,Mitigation Area lb adds an additional 37,353 square feet.For the Wetland G buffer,mitigation compensates for impacts at a ratio of greater than 5:1.For the Wetland F buffer,mitigation compensates for impacts at a ratio of greater than 6:1.In total, 119,924 square feet of mitigation compensates for 33,812 square feet of buffer impacts, at a ratio of greater than 3:1. 11 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13, 2020 Campground Relocation Project Phase 1 Table 3.

The mulch is intended to allow the re-establishment of native vegetation over time. Finally,while not proposed as mitigation for Phase 1,it is worth mentioning that future phases of Concept Plan implementation will significantly reduce the extent of park development on the west side of West Schafer Park Road due to its susceptibility to flooding.Therefore,future phases of the project are anticipated to have additional beneficial effects on ecological functions within the park. 4.2.1 .1 Maintenance & Monitoring State Parks staff regularly manage all vegetation at the park,including a successful effort to install and maintain many root-rot resistant tree species after the area was logge.Additionally, State Parks will comply with any specific maintenance and monitoring protocols required by Mason County. 4. 3 No Net Loss Mason County's SMP requires that projects do not result in a net loss of shoreline ecological functions. As discussed in detail above, the Mitigation Planting plans propose mitigation at three locations,including at one area immediately adjacent to the East Fork Satsop River, a high-value location for mitigation.In total, 119,924 SF of mitigation compensates for 33,812 square feet of buffer impacts, a ratio of greater than 3:1.Accordingly,no net loss of shoreline ecological functions is anticipated as a result of the proposed project. 12 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13, 2020 Campground Relocation Project Phase 1 5 Summary The Washington State Parks and Recreation Commission currently seeks to construct Phase 1 of the Schafer State Park Campground Relocation project,based on the Concept Plan. Phase 1 will expand campground development at a location in the park that will be less susceptible to flooding. The Phase 1 project area features existing campground development,including structures, internal roads, and hiking trails.Four wetlands (A,B, F and G) are located withing the Phase 1 project area. The East Fork Satsop River runs along the eastern portion of the Phase 1 project area. Wetland A has a standard buffer of 225 feet, and Wetlands B, F and G have standard buffers of 110 feet.The East Fork Satsop River has a 150-foot standard buffer. The project avoids direct impacts to wetlands and streams.While the design team has sought to avoid impacts to buffer areas,complete avoidance of buffer areas is not feasible given their extensive encumbrance of the Phase 1 project area and the infrastructure needed for a viable project. In general,projects with buffer impacts typically provide mitigation at a 1:1 ratio. However, for this project,because the Mitigation Planting plans propose extensive infill planting,except for Mitigation Area la,the plans provide mitigation for buffer impacts in exceedance of the typical 1:1 ratio. In total, 119,924 square feet of mitigation compensates for 33,812 square feet of buffer impacts,at a ratio of greater than 3:1. No net loss of shoreline ecological functions is anticipated as a result of the proposed project. 13 Compensatory Mitigation Plan/Habitat Management Plan The Watershed Company Schafer State Park November 13, 2020 Campground Relocation Project Phase 1 References J.A.

Brennan Associates,PLLC 2701 First Ave, Suite 510 Seattle, WA 98121 Re: Schafer State Park, Wetland & Stream Delineation Report The Watershed Company Reference Number:180615 Dear Jim: On December 4 and 5,2019, Ecologists Katy Crandall and Grace Brennan visited Schafer State Park,located at 1365 West Schafer Park Road in unincorporated Mason County near Elma, Washington,to delineate jurisdictional wetlands and streams that were previously identified in a 2018 reconnaissance investigation(The Watershed Company 2018). This letter summarizes the findings of the delineation study and provides updates on regulatory implications.The following documents are enclosed: • Phase 1 Scoping Diagram • Delineation sketch • Wetland Determination Data Forms • Wetland rating forms and figures Findings Summary The East Fork Satsop River and five wetlands (A,B, C,F and G) are either located within the Phase 1 study area or likely have buffers that extend into the study area. The river is a Shoreline of the State and features a 150-foot standard buffer. All five wetlands represent shoreline- associated wetlands.Wetlands A and C are Category II wetlands with eight habitat points. Wetland B is a Category III wetland with seven habitat points.Wetland F is a Category II wetland with seven habitat points. Wetland G is a Category II wetland with six habitat points. Mason County requires a standard buffer of 225 feet for Category II wetlands with high habitat scores (8-9) and a standard buffer of 110 feet for Category II and III wetlands with moderate habitat scores(5-7). 750 Sixth Street South I Kirkland, WA 98033 P 425.822.5242 1 f 425.827.8136 I watershedco.com Schafer State Park The Watershed Company Wetland &Stream Delineation Report January 27, 2020 Page 2 Study Area For the East Fork Satsop River,the study area for this report begins at the eastern property line and extends to the west approximately 1,000 feet. For wetlands,the study area for this report is the area shown on Sheets 1 and 2 of the Phase 1 Scoping Diagram dated 9/24/19(enclosed). Much of Schafer State Park was previously screened for wetlands as part of the reconnaissance investigation,including the entirety of the portion of the park located south of the East Fork Satsop River and east of West Schafer Park Road. Wetlands A,B,C,F and G,which were identified during the reconnaissance investigation, are either located within the study area or likely have buffers that extend into the study area, and were the subjects of this delineation study. Methods Public-domain information was reviewed for this delineation study.Resources and review findings are presented in Table 1 of the Findings section of this letter. The study area was evaluated for wetlands using methodology from the Corps of Engineers Wetland Delineation Manual (Environmental Laboratory 1987) and 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 2010). Presence or absence of wetlands was determined on the basis of an examination of vegetation, soils and hydrology. These parameters were sampled at several locations along wetland boundaries to determine the approximate wetland edges. Wetlands were classified using Washington State Department of Ecology's 2014 rating system (Hruby 2014). Characterization of climatic conditions for precipitation in the Wetland Determination Data Forms were determined using the WETS table methodology(USDA, NRCS 2015).The "Elora" station from 1981-2010 was used as a source for precipitation data.The WETS table methodology uses climate data from the three months prior to the site visit month to determine if normal conditions are present in the study area region. The study area was evaluated for streams based on the presence or absence of an ordinary high water mark as defined by Section 404 of the Clean Water Act,the Washington Administrative Code 220-660-030,and the Revised Code of Washington 90.58.030. The ordinary high water mark of the left bank of East Fork Satsop River was delineated using guidance from Determining the Ordinary High Water Mark for Shoreline Management Action Compliance in Washington State (Anderson et al.2016). Schafer State Park The Watershed Company Wetland &Stream Delineation Report January 27,2020 Page 3 Findings The study area is within in the Satsop sub-basin of the Lower Chehalis watershed (WRIA 22); Section 29 of Township 19 North, Range 06 West of the Public Land Survey System. It is situated along the East Fork of the Satsop River, about six miles upstream of the confluence with the West Fork of the Satsop River. Schafer State Park is 113 acres in size and developed with recreational facilities, including many campsites. Large portions of the site remain partially undeveloped,with trails or small roads running through them. The study area, as well as most adjacent areas in the vicinity, is zoned Rural Residential 10. Existing land uses in the vicinity of the study area outside the park include low-intensity residential, forestry and undeveloped lands. Reviewed public-domain information for the site is summarized below(Table 1). Table 1. Summary of online mapping and inventory resources.

Schafer State Park The Watershed Company Wetland &Stream Delineation Report January 27, 2020 Page 9 Two riverine wetlands,Wetlands D and E,identified in the prior wetland reconnaissance investigation,were re-examined during this delineation study,but not delineated. Both wetlands are situated along left bank of the East Fork Satsop River.Wetland D is dominated by willow and reed canarygrass (Photo 1,page 12).Wetland E is dominated by alder, slough sedge, and piggy-back plant(Photo 2,page 12).The approximate size and shape of Wetlands D and E are similar to or smaller than the results depicted in the 2018 reconnaissance investigation.Buffers from these wetlands are not expected to encumber planned Phase 1 site development. One flag was hung on the most encumbering boundary of Wetland E for verification. Non-wetlands Non-wetland areas were generally upslope of wetlands and did not meet criteria for hydrophytic vegetation,hydric soils, or wetland hydrology. Areas around Wetlands A(Photo 3,page 13) and B and along the adjacent trail were dominated by a bigleaf maple canopy and had a snowberry,salmonberry,vine maple,and sword fern understory. The area surrounding Wetland C,in between the river and the large, gravel parking lot,is sparsely vegetated with Himalayan blackberry,evergreen blackberry,sword fern and salal. This vegetated area is surrounded by hard-packed crushed rock and gravel,with a river cobble corridor that connects the parking lot to the river and separates Wetland C from D. The swale/depression in which Wetlands B and F are situated is vegetated with salmonberry, snowberry, and sword fern(outside of the wetlands).The non-wetland areas within the swale are generally slightly higher than the wetland depressions.Adjacent upslope areas are dominated by a bigleaf maple canopy with a sword fern, salal, and snowberry understory. In the areas adjacent to the picnic area and parking lot,vegetation is dominated by a bigleaf maple and Douglas-fir canopy with a lawn grass understory,with patches of Himalayan blackberry and hedges of snowberry(Photo 4,page 13). The area surrounding Wetland G has a younger,more diverse plant community, possibly due to semi-recent disturbance.Alder saplings are prolific in this area,along with planted conifers such as western red cedar, shore pine, and white pine. Invasives in this area include scotch broom and Himalayan blackberry(Photo 5,page 14).The north side of the driveway to the ranger station is dominated by sword fern,salal, and snowberry. Schafer State Park The Watershed Company Wetland &Stream Delineation Report January 27, 2020 Page 10 Much of the park located to the east of West Schafer Park Road has recently been logged due to widespread Douglas-fir root rot infection.This includes much of the Phase 1 project area.This area has been replanted with a variety of conifers,including western red cedar,shore pine, white pine, and Sitka spruce.This area has low canopy coverage due to the recent logging,with some bigleaf maple providing canopy cover.The understory is very diverse and includes snowberry,low Oregon grape,salal, and trailing blackberry(Photo 6,page 14).Micro- depressions are present throughout this area,but these lower areas did not meet wetland criteria requirements. Substrate in this area is heavily influenced by a large amount of downed woody debris and remnant stumps from logging. Regulatory Implications The applicability of local regulations to development at the park has been extensively documented in prior project documentation.The discussion in this section provides updates to regulatory implications based on the findings of this delineation study and site survey. The study area includes areas both inside and outside of Mason County's shoreline jurisdiction. Areas inside shoreline jurisdiction are subject to the Mason County Shoreline Master Program (SMP).In the study area, such areas include uplands within 200 feet of the ordinary high water mark of the East Fork Satsop River, as well as shoreline-associated wetlands. All wetlands delineated as part of this study(Wetlands A,B, C,F, and G)represent shoreline-associated wetlands. The SMP, subject to certain exceptions,refers to the Mason County Resource Ordinance,which includes provisions for critical areas. Wetland & Stream Buffers Wetlands A and C are Category II wetlands with eight habitat points.Wetlands B and F are Category II wetlands with seven habitat points.Wetland G is a Category II wetland with six habitat points.Mason County requires a standard 225-foot buffer for Category II wetlands with high habitat scores(8-9)and a standard buffer of 110 feet for Category II wetlands with moderate habitat scores(5-7). Therefore,Wetlands A and C have standard buffers of 225 feet, and Wetlands B,F and G have standard buffers of 110 feet(Table 7). The East Fork Satsop River has a 150-foot standard buffer. Structure setbacks of 15 feet from wetland and stream buffers are also required. Schafer State Park The Watershed Company Wetland &Stream Delineation Report January 27, 2020 Page 11 Table 7.

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 except during floods? ®NO -go to 2 El YES -the wetland class is Tidal Fringe-go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES- Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 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. ®NO -go to 3 DYES-The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? El The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; ❑At least 30% of the open water area is deeper than 6.6 ft (2 m). ®NO -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 verygradual), ❑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. ®NO -go to 5 ❑YES-The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually<3 ft diameter and less than 1 ft deep). S. Does the entire wetland unit 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 2 years. Wetland Rating System for Western WA:2014 Update 3 Rating Form-Effective January 1,2015 Wetland name or number: Wetland A ❑NO -go to 6 ®YES-The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface,at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. ❑NO -go to 7 DYES -The wetland class is Depressional 7. 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 DYES -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 the wetland unit being scored. 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 HGM 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. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope+ Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland T ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

NO -Saltwater Tidal Fringe (Estuarine) YES-Freshwater Tidal Fringe Ifyour wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 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. ONO -go to 3 ❑YES-The wetland class is Flats Ifyour wetland can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? ❑The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; ❑At least 30% of the open water area is deeper than 6.6 ft(2 m). ®NO -go to 4 [1 YES-The wetland class is Lake Fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? El 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. ®NO -go to 5 El YES-The wetland class is Slope NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). S. Does the entire wetland unit 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 2 years.

Is the entire wetland unit in a topographic depression in which water ponds,or is saturated to the surface,at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. ONO-go to 7 ®YES-The wetland class is Depressional 7. 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. ONO-go to 8 OYES-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 the wetland unit being scored. 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 HGM 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. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Is the entire wetland unit in a topographic depression in which water ponds,or is saturated to the surface,at sometime during 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 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 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 the wetland unit being scored. 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 HGM 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. HGM classes within the wetland unit HGM class to being rated use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface,at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. ❑NO -go to 7 ❑X YES -The wetland class is Depressional 7. 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 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 the wetland unit being scored. 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 HGM 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. HGM classes within the wetland unit HGM class to being rated use in rating Slope+ Riverine Riverine Slope + Depressional Depressional Slope+ Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface,at sometime during 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 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 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 the wetland unit being scored. 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 HGM 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. HGM classes within the wetland unit HGM class to being rated use in rating Slope+ Riverine Riverine Slope + Depressional Depressional Slope+ Lake Fringe Lake Fringe Depressional + Riverine along stream Depressional within boundary of depression Depressional + Lake Fringe Depressional Riverine+ Lake Fringe Riverine Salt Water Tidal Fringe and any other Treat as class of freshwater wetland ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.
