Federal Way Ms. Sheila Ranganath Washington State Parks and Recreation Commission 220 North Walnut Street Burlington, WA 98233-1138 Re: File #20-100118-UP; PROCESS I "DIRECTOR'S APPROVAL" 33325 8M Avenue South Federal Way, WA 98003-6325 253-835-7000 %vwwxit offederalwa .porn Jim Ferrell, Mayor Dash Point State Park Improvements, 5300 SW 324th Place, Federal Way Dear Ms. Ranganath: March 25, 2020 The Community Development Department has completed review of your Process I Master Land Use application for trail improvements in Dash Point State Park (DPSP); with construction access through Dash Point Highlands Park (DPHP), located at 5300 SW 324d, Place (parcel #1898310470), and 5700 Dash Point Road (parcel #1521039001). Only a portion of the overall project is within the city limits; all bridge work is taking place outside the city limits in unincorporated Pierce County. The Process I application is hereby approved per the findings, conclusions, and condition noted below. FINDINGS OF FACT 1. The applicant proposes to complete a series of pedestrian trail improvements at DPSP; less than 200 feet of the proposed trail is within the city limits, with the remainder of the project occurring in unincorporated Pierce County. More specifically activities include: a. Closure of a portion of an existing unsanctioned social trail and planting with native vegetation (approximately 420 square feet); and b. Formalizing and improving an existing social trail, and grading as required for safety and access (approximately 600 square feet); and c. Temporary access from DPHP on the eastern side of the DPSP (approximately 1,250 linear feet of existing foot paths). A portion of the construction access route passes through the outer portion of the buffer of Stream 6, however there are no permanent improvements to the existing foot path proposed to be used for construction access. The contractor may use temporary measures to improve construction access and prevent erosion. 2. The zoning for the property at 5700 SW Dash Point Road (parcel 1521039001) is Suburban Estate (SE). The existing state park (DPSP) is an allowed use in the SE zone per Federal Tway Remised Code (FWRC) 19.195.160, "Public parks." 3. The zoning for the property at 5300 SW 3241h Place (parcel #1898310470) is Single -Family Residential (RS 9.6). The existing city park (DPHP) is an allowed use in the RS 9.6 zone per FWRC 19.200.160, "Public parks." Ms. Sheila Ranganath Page 2 of 3 March 25, 2020 4. Per FWRC 19.15.030(1), minor improvements and modifications to a site such as parking lot and landscape area modifications and improvements, and/or additions to an existing developed site that are exempt from SEPA, shall be processed using Process I. 5. While not triggered by any work proposed within the city, the Washington State Parks and Recreation Commission issued a SEPA Determination of Nonsignificance (DNS) for the project on April 5, 2019. 6. Given the nature of the trail improvements within the larger state park property, and temporary nature of the construction access component of the project, no new parking is proposed or recommend per FWRC 19.195.160 and FWRC 19.200.160. 7. Limited tree removal may occur as part of the project. DPSP is heavily treed and complies with FWRC 19.120.130(2). 8. On -site critical areas include Wetland B-C and Wetland D, Category IV wetlands with 50-foot buffers per FWRC 19.145.420(2). Stream 3 a Type F stream with a 100-foot buffer, and Stream is a Type Np stream with a 50-foot buffe per FWRC 19.145.270(1). The applicant submitted an April 30, 2019, Fish & Wild HabitatAssessmmf Study & Vetland Analysis Report, prepared by PBS. The report was prepared prior to the critical areas code update adopted on July 2, 2019, via Ordinance No. 19-873. The only change applicable to this report is the buffer width for a Category IV wetland from the 40 feet noted in the report, to 50 feet required in the version of the code in effect at the time the land use application was submitted. 9. The project does not anticipate impacts to critical areas and their buffers, apart from a portion of the construction access route passing through the outer portion of the buffer of Stream 6 via an existing foot path. There are no permanent improvements to the existing foot path proposed to be used for construction access. The contractor may use temporary measures to improve construction access and prevent erosion. This activity qualifies for a Critical Areas Code Exemption per FWRC 19.145.110(2): a. "Operation, maintenance, or repair of existing public improvements, utilities, public or private roads, parks, trails, or drainage systems if the activity does not further alter or increase impact to, or encroach further within, the critical area or buffer and there is no increased risk to life or property as a result of the proposed operation, maintenance, or repair, and no new clearing of native vegetation beyond routine pruning." 10. Per FWRC 19.15.100(1), the applicant must substantially complete construction for the development activity, use of land, or other actions approved; and complete the applicable conditions listed in the Process I decision within one year after the final decision of the city on the matter. The applicant's project schedule includes work windows and the last component of the project, mitigation plantings/ revegetation, may occur beyond the one-year allotted per FWRC 19.15.100(1). As long as the project construction is substantially complete within one year after the final decision, then the project may rely on this approval to complete minor remaining project components and not have to re -apply, unless there is some other trigger, such as the project scope chanceiRag significantly. 11. A building permit is not required for the project, as the bridge work is proposed outside the city. 12. The Public Works Traffic Division reviewed the submittal and has no comments. 13. The applicant submitted a Construction Stormwater Pollution Prevention Plan (SWPP). Public Works Development Services reviewed the submittal and along with the City Parks Department, met WA State Parks on site. The state's contractor will need to obtain an Engineering (EN) Permit from the city, for the use of Dash Point Highlands Park for access, as well as for construction materials storage and staging. A condition of this Process I shall state that the state's contractor is required to apply for an Engineering (EN) Permit, and shall obtain city approval of the EN, prior to any use of the city park. 14. Lakehaven is the sewer service purveyor for the site. Lakehaven reviewed the submittal and has no comments. 15. South King Fire & Rescue reviewed the submittal and does not have any comments or concerns. 20-100118-UP D« ID 80289 Ms. Sheila Ranganath Page 3 of 3 March 25, 2020 CONCLUSIONS OF LAW 1. The proposed improvements are not exempt from use process review as they do not meet criteria set forth in FWRC 19.15.020, "Exceptions." 2. Process I "Director's Decision" is the appropriate Master Land Use application as the improvements are to a developed site and do not exceed thresholds set forth in FWRC 19.15.030(1). 3. The proposed improvements comply with zoning regulations set forth in Use zone Charts FWRC 19.195.160 and 19.200.160, including required yards, lot coverage, height, and parking. 4. The proposed improvements meet Process I purpose criteria set forth in FWRC 19.55.020, including compliance with applicable provisions of FWRC Title 19, "Zoning and Development Code," and health, safety, and welfare standards. CONDITION OF APPROVAL The applicant or their contractor is required to apply for an Engineering (EN) Permit, and shall obtain city approval of the EN prior to any use of Dash Point Highlands Park. APPRAT S The effective date of this decision per FWRC 19.05.360 is March 28, 2020.

The Commission has an upcoming footbridge replacement project within Dash Point State Park, for which Contractor(s) access through Dash Point Highlands Park is requested (See Sheet 5, Site Plans, Attachment F). The anticipated primary windows during which access will likely be needed are: during the Washington Department of Fish and Wildlife (WDFW) fish window (June 15th —September 30th) and through the mitigation planting period November 2020. Prior to the commencement of work the Contractor(s) are required to provide a schedule for completing the work, the Commission will provide this information to the City once it is available. The primary activities associated with this project are: 1) Demolition of two existing wooden footbridges (large and small) 2) Installation of anew footbridge 3) Improvement/formalization of an existing trail to the new footbridge 4) Planting along the existing (closed) trail to the wooden footbridges to be removed The existing large footbridge crosses a stream in a steep walled ravine that has started to collapse due to soil erosion; the footbridge is now closed to the public. The Park is effectively divided due to closure of the existing large footbridge and adjoining trail, thereby limiting access to visitors. The installation of a new footbridge would provide much sought-after access to both halves of the Park. Over the past several years, alternatives to replace the bridge in its existing location have been analyzed and determined to be infeasible —due to site accessibility, channel span, and unstable slopes. Therefore, a geotechnical evaluation of the area was completed to determine the optimal location for a new footbridge. From this analysis a site further downstream (where slope conditions are more favorable) from the existing bridge location was identified for a replacement bridge. Replacing the footbridge in the new location will also resolve and formalize an unsanctioned social trail in the Park. A small portion (less than 200 linear feet) of the proposed trail is located within the City of Federal Way. Per communication with City of Federal Way staff on March 11, 2019 the following permits would be required from City of Federal Way for this project: Master Land Use Application Northwest Region HQ o 220 N.

The improvements include the removal and replacement of a pedestrian bridge, removal of a second small pedestrian bridge, decommissioning and revegetation of an existing trail, and formalizing an unsanctioned social trail in the Park to access the replacement footbridge. Materials are proposed to be moved on and off site utilizing existing DPSP trails. The majority of the active work areas are concentrated around two stream valleys in the central part of the Park, which is within unincorporated Pierce County. PBS Engineering and Environmental Inc. (PBS) prepared a Wetland Analysis Report and Habitat Assessment Study (see Attachment B, Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report). The report details delineated wetlands and streams and for the project area and describes the critical areas and corresponding buffers in the project vicinity. This report addresses the entire project, including areas within the City of Federal Way, and the study area extends a minimum of 225 feet from the project (Federal Way Municipal Code 19.145.410). The field studies identified two streams (Stream 3 [Type F] and Stream 6 [Type Np]) and two wetlands (Wetlands B and D, both Category IV) within the City of Federal Way portion of the study area. Project activities proposed within the City of Federal Way include (see Sheet 20, Site Plans): e Closure of a portion of an existing unsanctioned social trail and planting with native vegetation (approximately 420 square feet); Northwest Region HQ o 220 N.

A portion of the southernmost access route passes through the buffer of Stream 6. There are no permanent improvements to the trails being proposed for construction access, but the Contractor may use temporary measures (such as gravel) to improve construction access and prevent erosion. Additionally, no clearing or grading is proposed in streams, wetlands, or buffers within the City of Federal Way.

Walnut Street ■ Burlington, Washington 98233 . (360) 755-5262 • Fax (360) 428-1094 STATE ENVIRONMENTAL POLICY ACT DETERMINATION OF NON -SIGNIFICANCE Date of Issuance: April 5, 2019 Lead Agency: Washington State Parks and Recreation Commission Agency Contact: Kira Swanson, Environmental Planner kira.swanson arks.wa. ov (360) 755-2835 Description of Proposal: Washington State Parks and Recreation Commission (Commission) proposes to replace a failing 65-foot-long footbridge at Dash Point State Park to increase user safety and general park accessibility. The footbridge is now closed to the public and park users have established an unsanctioned social trail and stream crossing approximately 500 feet downstream. The failing footbridge crosses a potentially fish -bearing stream in a steep walled ravine with unstable slopes and has started to collapse. There are wood platforms and stairs adjacent to the footbridge that cover approximately 415 square feet. The proposed project will include: the removal of the existing footbridge wood platforms and stairs; abandonment of the access trail to the failing footbridge; and restoration and revegetation (with native plant species) of all disturbed or abandoned areas. A replacement footbridge is proposed at a site approximately 500 feet downstream, where slope conditions are more stable, and users have established an unsanctioned trail and stream crossing. The new footbridge will be 40 feet long and 5 feet wide and require new concrete footers. The proposed trail will be relocated to provide access to the new footbridge location. A second, smaller footbridge (17 feet long) will be removed as part of the trail realignment. All proposed work will occur above the Ordinary High Water Mark (OHWM) of associated streams. All of the footbridge work and a majority of the new trail alignment will occur in unincorporated Pierce County. A short segment of the proposed new trail is within the City of Federal Way, King County, WA. Proponent: Washington State Parks and Recreation Commission Location of Proposal: Dash Point State Park: 5700 SW Dash Point Road, Federal Way, WA 98023. The project is located within the southwest 1/a of Section 15, Township 21 North, Range 03 East, Willamette Meridian, Pierce County parcel number 0321152001. Page 1 of 2 The. lead agency (Washington State Parks and Recreation Commission) has determined that this proposal will not have a probable significant adverse impact on (fie environment, An envirotunenlal impact statement (EIS) is not required under RCW 43.21 C,030(2)(c). This decision was made after review of a completed environmental checklist and other information on file with the lead agency. This information is available at: hlip:llbit.ly/Parl.sSl1'PA This determination is based on the following findings and conclusions: 1. All Work will be consistent with Washington State Parks and Recreation Cominission=s Cultural Resource Management Policy. 2. The proposed project will comply with Washington State Parks and Recreation Commission's Natural Resource Management Policy 1173-04-1 Prolecling Washitaglon Slate Parks' Nalural Resources. 3. Site; specific Best Management Practices (11MPs) will be used to preveiat soil erosion in all construction areas, 4. For final grading that iakcs place after October 1, additional TESL (fempoiary Erosion Sediment Control) measures will be implemented to ensure that the exposed areas are stabilized. 5. Biodegradable wattles or coin fabric logs and native plantings will be installed along abandoned trail portions to reduce surface water runoff and erosion. 6. Native vegetation enhancement will occur to restore areas disturbed during construction and revege(ate abandoned trail areas. 7. Containment measures will be taken to avoid debris or other materials from entering waters of the State during removal of existing footbridge. 8. There will be a net decrease of impervious surface by 390 square feet as a result of the project. The project will have no impact on drainage patterns. The trail to be abandoned and revegetated will likely infiltrate a similar amount of water and the net decrease in impervious surface will allow more infiltration of water, This DNS is issued under 197-11-340 (2); the lead agency will not act on this proposal for t4 days from the date below.

Dash Point State Park spans the county line between Pierce County and King County, with the City of Tacoma to the south and the City of Federal Way to the north. It is located in Section 15, Township 21 North, Range 03 East (See Figure 1). The Pierce County portion of SEPA Environmental Checklist (WAC 197-11-960) July 2016 Page 2 of 15 Dash Point State Park Footbridge Replacement SEPA Checklist the park is within unincorporated Pierce County and the King County portion is within the City of Federal Way. The park address is 5700 SW Dash Point Road, Federal Way, WA 98023. Southwest Dash Point Road runs east -west and bisects the park. The coordinates of the center of the study area are latitude 47.312829N and longitude-122.408870W. The project study area includes portions of 9 tax parcels, 7 in Pierce County (0321151000, - 1002, -2001, -2002, -2010, -6028, -6029) and 2 in King County (1521039001 and 1898310470). An overview of the project area is shown in attached Sheet Plan Page 1. B. ENVIRONMENTAL ELEMENTS 1. Earth a. General description of the site: 0 flat rolling Ohilly Osteep slopes mountainous other b. What is the steepest slope on the site (approximate percent slope)? 70 percent c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any agricultural land of long-term commercial significance and whether the proposal results in removing any of these soils. The following soil summary is based on information from the United States Department of Agriculture Natural Resources Conservation Service Web Soil Survey (NRCS 2018a). Soils on the eastern portion of the site are Alderwood gravelly sandy loam with 8 to 15 percent slopes. The Alderwood soils are moderately deep, moderately well drained soils that formed in glacial drift and outwash over dense glaciomarine deposits. Soils along the stream valleys in the project area are mapped as Ragnar sandy loam with 0 to 6 percent slopes. The Ragnar soils are well drained with a restrictive layer between 20 and 40 inches deep. These soils formed on glacial outwash. Soils on the western terraces of the site are Indianola loamy sand with 5 to 15 percent slopes. Indianola soils are deep, somewhat excessively well drained soils that formed in sandy glacial outwash. Soil removal will be limited to regrading during the trail realignment (Alderwood gravelly sandy loam) and excavation for the new bridge footers (Ragnar sandy loam) and is not anticipated to affect soil quality or fertility on site. Disturbed areas will be covered with compost and biodegradable erosion control material to prevent additional soil loss. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. The soils supporting the failing footbridge display evidence of sloughing and unstable conditions. The soils in the proposed footbridge area were evaluated by a geologist (GeoEngineers, Inc) who found no evidence of slope instability. Additional detail regarding unstable soils can be found in the Landslide Hazard Geotechnical Letter and Proposed Trail Bridge Foundation Recommendations Dash Point State Park, Dated July 8, 2016, prepared by GeoEngineers. e. Describe the purpose, type, total area, and approximate quantities and total affected area of any filling, excavation, and grading proposed. Indicate source of fill. The project will result in the following cut/fill quantities: SEPA Environmental Checklist (WAC 197-11-960) July 2016 Page 3 of 15 Dash Point State Park Footbridge Replacement SEPA Checklist New Trail: Cut Quantity — 510 cubic yards (reused for fill, any excess material to be disposed of off - site) Fill Quantity — 550 cubic yards (native and import 2" of bedding material) New Footbridge (40 length): Cut Quantity — 10 cubic yards (disposed of off -site) Fill Quantity — 2 cubic yards (import 4" of bedding material) Old Footbridge (65 foot long, to be removed) Eight existing footers (CMPs filled with concrete) to be removed — 35 cubic yards fill (native) Old Footbridge (17 foot long, and crib wall to be removed) Cut and Fill 10 cubic yards (native) Could erosion occur as a result of clearing, construction, or use? If so, generally describe. There is some possibility of erosion during and immediately following the removal of the two footbridges and adjacent wood platforms. There is also possible erosion associated with soil disturbance for the new footbridge construction and trail realignment. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? The two existing footbridges and adjacent wooden platforms contribute approximately 630 ft2 of impervious surface. The new footbridge and footers will contribute 240 ft2 of impervious surface. There will be a net decrease in impervious surface of 390 ft2. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: All clearing activities and the majority of the soil disturbance/trail construction/demolition work is proposed to take place before October 1st. Parks is proposing the removal of two existing footbridges and the installation of a premanufactured footbridge between August and October (estimated). Final grading for the pedestrian bridge and proposed trail, trail closure, and mitigation plantings will be completed after October 1st. Once the pedestrian bridge is installed, final grading of new trail will be completed (estimated October/November) and replanting of the trails to be abandoned (November -February). All disturbed areas including the decommissioned trails will be restored with native plant species. Best management practices will be used to prevent erosion in all construction areas. These will include installing biodegradable wattles or coir fabric logs, compost, and erosion control fabric on the steep slopes by the footbridge removal and installation SEPA Environmental Checklist (WAC 197-11-960) July 2016 Page 4 of 15 Dash Point State Park Footbridge Replacement SEPA Checklist sites. The trails are bare earth pedestrian trails and are not anticipated to result in increased erosion. If needed, water bars or equivalent trail protection measures may be installed as part of routine maintenance. For final grading that takes place after October 1, additional TESC measures will be implemented to ensure that the exposed areas are stabilized. 2. Air a. What types of emissions to the air would result from the proposal during construction, operation, and maintenance when the project is completed? If any, generally describe and give approximate quantities if known. Tools to be used during construction may include portable gas power tools, such as power wheelbarrows and chainsaws. The use of these tools may result in localized, short term emissions and potential fugitive dust. During demolition of the existing footbridges, the Contractor will avoid saw cutting the treated wood to avoid saw -dust potential by removing the footbridge in component pieces. The completed project will have no long-term air emissions. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. There are no off -site sources of emissions that would affect the proposed project. c. Proposed measures to reduce or control emissions or other impacts to air, if any: All equipment operating at the site will be required to meet state emissions standards, and best management practices will be used during construction to minimize potential fugitive dust. 3. Water a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. Type Name Classification Flows or Connects to Streams Unnamed stream 1 Type F2 Puget Sound Unnamed stream 2 Type F2 Stream 1 Unnamed stream 3 Type N1 Stream 1 Unnamed stream 4 Type N1 Stream 1 Unnamed Steam 5 Type N1 Stream 4 Unnamed Stream 6 Type N2 Wetland Wetlands 10 mapped wetlands Cowardin Classification Stream 1 and tributaries - Palustrine Emergent - Palustrine Scrub -Shrub - Palustrine Forested HGM Classification - Slope - Riverine - Depressional SEPA Environmental Checklist (WAC 197-11-960) July 2016 Page 5of15 Dash Point State Park Footbridge Replacement SEPA Checklist 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes, footbridge removal and construction will occur over streams 1 and 2 and within 200 feet a 9 acre, category IV, slope wetland. Trail realignment will occur within 200 feet of stream 1 and the 9 acre wetland. Plan drawings for the project are attached. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. No material will be placed in or removed from surface waters or wetlands as part of this project. a) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. No, this project will not require any surface water withdrawals or diversions. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. The project will not lie within the 100 year floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. The project does not involve any discharges of waste materials to surface waters. Tarps and netting will be secured below the existing footbridges during removal to prevent discharges of waste materials to surface waters. b. Ground Water: 1) Will groundwater be withdrawn from a well for drinking water or other purposes? If so, give a general description of the well, proposed uses and approximate quantities withdrawn from the well. Will water be discharged to groundwater? Give general description, purpose, and approximate quantities if known. No, groundwater will not be withdrawn as part of this project. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the following chemicals... ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. This project does not involve the discharge of waste material to the ground. c. Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. Stormwater runoff from the 200 ft2 new footbridge will flow into stream 1. 2) Could waste materials enter ground or surface waters? If so, generally describe. Waste materials, such as pieces of treated lumber, could enter surface water during demolition and construction if materials fall outside of the tarps and netting secured below the existing footbridges during removal. 3) Does the proposal alter or otherwise affect drainage patterns in the vicinity of the site? If so, describe. SEPA Environmental Checklist (WAG 197-11-960) July 2016 Page 6 of 15 Dash Point State Park Footbridge Replacement SEPA Checklist The will be a net decrease of impervious surface by 390 square feet as a result of the project. The project will have no impact on drainage patterns. The trail to be abandoned and revegetated will likely infiltrate a similar amount of water and the net decrease in impervious surface will allow more infiltration of water. The new trail follows the alignment of the unsanctioned social trail for the majority of its alignment and is not anticipated to affect drainage patterns. d. Proposed measures to reduce or control surface, ground, and runoff water, and drainage pattern impacts, if any: The project will incorporate the installation of biodegradable wattles or coir fabric logs, compost, and erosion control fabric on disturbed steep slope areas to control runoff. Native plantings will be installed along abandoned trial portions to reduce potential surface water runoff. 4. Plants a. Check the types of vegetation found on the site: _X—deciduous tree: alder, maple, aspen, other _X—evergreen tree: fir, cedar, pine, other _X—shrubs X grass pasture crop or grain Orchards, vineyards or other permanent crops. X wet soil plants: cattail, buttercup, bullrush, skunk cabbage water plants: water lily, other other types of vegetation b. What kind and amount of vegetation will be removed or altered? Three alder trees, five maple tree, and two Douglas fir trees will be removed during the trail realignment and footbridge construction due to unavoidable root zone impacts or hazardous conditions. Approximately 550 square feet of native understory vegetation will be disturbed and replanted surrounding the new footbridge crossing.

It falls within Section 15, Township 21 North, Range 03 East. The Pierce County portion of the project area is within unincorporated Pierce County and the King County portion is within the city boundary of Federal Way. The study area (Figure 2) includes the project footprint and the potential access trails with a surrounding 315-foot buffer in Pierce County (PCC 18E.30.020.C.2) and 225-foot buffer in Federal Way (Federal Way Municipal Code 19.145.410). The project study area within the park boundaries includes portions of 9 tax parcels, 7 in Pierce County (0321151000, - 1002, -2001, -2002, -2010, -6028, -6029) and 2 in King County (1521039001 and 1898310470). The Pierce County parcels are zoned Single Family and the King County/Federal Way parcel is zoned Residential (R). The parcels are within the Urban Growth Boundary for both counties. Parcel -2010 is an unaddressed property east of Agnes Rd NE; -2001 and -1002 are unaddressed properties north of Manito Ct NE, and -1000 is an unaddressed property east of Nanaimo Ct NE. The other parcels currently have no road frontage or addresses. Southwest Dash Point Road runs east -west and bisects the park. The coordinates of the center of the study area are latitude 47.312829N and longitude-122.408870W. 2.2 Landscape Setting/Topography Dash Point State Park is in an unnamed drainage basin (HUC 171100190204) that is part of the Puyallup/White River Water Resource Inventory Area (WRIA 10). The drainage basin is approximately 1.04 square miles and generally slopes to the north with elevations ranging from 305 to 543 feet in elevation. Within the park boundary, the topography consists of five steeply incised stream valleys surrounded by upland terraces. The streams flow northward into Puget Sound, and the confluence of these streams is 0.2 miles south of the Sound. 2.3 Soils and Geology The geology of this area is described as glacial outwash from the Vashon Stade of the Fraser glacial age overlain by Vashon glacial till. Based on site observations from Geoengineers Inc, the project area appears to be Vashon advance glacial outwash consisting of stratified sand and gravel with very little silt (Geoengineers, Inc 2016). Soils present in the site include Alderwood gravelly sandy loam, Indianola loamy sand, Kitsap silt loam, and Ragnar sandy loam (Web Soil Survey, NRCS 2018a).

Slope wetlands emerge from the valley walls along several of the streams. The drainage basin feeding these streams is approximately 641 acres in size (USGS 2016) and terminates in Puget Sound. 3.2 Stream Assessment The stream assessment included both office and field components. Details of these two components are provided below. 3.2.1 Office Methods We reviewed mapped streams from a variety of online sources including aerial photographs, the National Wetland Inventory, WA DOE Water Quality Atlas, Pierce County public GIS, King County iMap, Federal Way Critical Areas Map, WDNR LiDAR Portal, USGS StreamStats, Forest Practices Activity Mapping Tool, Salmonscape, etc. The mapping was limited in this basin; with several sources showing few or no mapped streams, and none of the sources providing stream names. The mapped reaches were given identifiers and reach numbers on Salmonscape.

Streams were typed and buffers widths determined based on the criteria in PCC 18E.40.060 and FWMC 19.145.260/270. The Ordinary High Water Mark (OHWM) of stream were flagged in the field with brightly colored plastic tape or pin flags and recorded with a Trimble handheld GPS unit (GeoXT) capable of sub -meter accuracy. Photographs were taken with a cell phone camera and locations were geotagged with the phone's GPS or referenced to positions collected with the handheld GPS unit. The portions of streams nearest the proposed work area were later professionally surveyed by Harmsen and Associates. 3.2.2.1 Stream 1 Stream 1 drains the central portion of the Park (Figure 5a). From its origin at a perched culvert north of Manito Court NE (Photo 1), Stream 1 flows northward for approximately 400 feet to its confluence with Stream 2. Stream 1 continues northward for another 750 feet flowing through Wetland B and C to its confluence with Stream 3. Stream 1 turnsjust the west south of the King County boundary (Sheet 1) and flows westward for approximately 750 feet to its confluence with Stream 4, and again turns north. Exiting the study area, Stream 1 continues flowing to the north, crossing under SW Dash Point Drive to terminate in Puget Sound. Numerous small seeps feed Stream 1 throughout its length. Within the study area, Stream 1 is confined to a steep ravine (Photos 2-4). The banks of the ravine are somewhat prone to sloughing, but are well vegetated and provide near 100 percent canopy coverage. Stream 1 is approximately 5- to 7-feet wide at the OHWM, and the substrate consists of native gravels and sands. Woody debris is abundant. 3.2.2.2 Stream 2 Stream 2 is located in the south-central portion of the Park (Figure 5a, 5b), and drains the area to the east of Stream 1. It begins south of the study area to the east of Nahane E NE. From the southern edge of the study area, Stream 2 flows northward for approximately 600 feet before entering Stream 1. Stream 2 is also confined by steep slopes (Photos 5 and 6), with relatively dense native vegetation providing near 100 percent canopy coverage. Stream 2 is approximately 3- to 6-feet wide at the OHWM, and the substrate consists of native gravels and sands. Woody debris is abundant. Wetland A is located just downstream of the confluence of the two streams. 3.2.2.3 Stream 3 Stream 3 is located to the northeast of Stream 1 (Figure 5b, 5c), and drains a portion of DPSP within the City of Federal Way. Wetland D is within this sub -drainage. From its origin in Wetland D, Stream 3 flows approximately 1,000 feet to the west. As with Streams 1 and 2, the channel of Stream 3 is confined to a steeply incised ravine (Photos 7 and 8). Within this ravine, Stream 3 is approximately 5- to 7-feet wide at the OHWM, and has a substrate of native gravels and sands. Woody debris is abundant, and canopy coverage near 100 percent. 3.2.2.4 Stream 4 Stream 4 drains the area in the southwestern corner of the study area (Figure 5d). From its origin outside DPSP, Stream 4 crosses under Nahame W NE and flows northward for approximately 200 feet, passing along the east side of Wetland E and crossing under the Boundary Trail, then continuing northward for approximately 900 feet to its confluence with Stream 5. From this point, Stream 4 continues northward for approximately 200 feet, to terminate in Stream 1. Stream 4 occupies a shallow fold in the slope, which is April 30, 2019 2 Z 4 PBS Project 40525.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Washington State Parks Service Dash Point State Park Pierce County, Washington neither as high or as steep as the ravines of Streams 1, 2, and 3 (Photos 9 and 10). Stream 4 is approximately 2-feet wide at the OHWM and has a substrate of native gravels and sands. Some side channel development is evident, and the banks are densely vegetated, providing full canopy cover. 3.2.2.5 Stream 5 Stream 5 begins north of Norma Road NE to the west of DPSP (Figure 5e). The stream passes over a series of rubble wall dams (e.g. shown in Photo 11), which retain flows and support the hydrology of Wetland Ga, Gb, and Gc. Stream 5 flows to the northeast approximately 400 feet, crossing under the Boundary Trail, flowing to the northeast; Stream 5 reaches its confluence with Stream 4 approximately 350 feet downstream of the trail. South of the Boundary Trail, the banks of Stream 5 are relatively shallow. To the north of the trail, Stream 5 is confined to a more narrow, steep sided ravine (Photos 1 - 14). The channel of Stream 5 is relatively narrow (2- to 3-feet wide) at the OHWM and has a gravel and cobble substrate. The banks are densely vegetated providing near full canopy cover, and small woody debris is relatively abundant. 3.2.2.6 Stream 6 Stream 6 begins at a stormwater overflow structure (Photo 15) in the southeast end of the study area, north of SW 26th Street (Sheet 1). The stream flows to the northwest approximately 450 feet in a poorly defined channel, to terminate in the southern end of Wetland D (Figure 5c). Stream 6 is approximately 2- to 3-feet wide and quite shallow, but appears to flow perennially. Approximately 300 feet to the north of its origin, Stream 6 is crossed by an eastward extension of the Boundary Trail (Photo 16 - 18), which spans the stream over a culvert. The substrate of Stream 6 is a mixture of gravels and fines. The banks are ill-defined in the upper reach, but densely vegetated with native shrubs, which provide near 100 percent canopy coverage. Smaller woody debris is present, though the stream lacks the flow to move larger materials. 3.2.3 Recommended Stream Types and Buffers Streams were typed and buffers widths determined based on the criteria in PCC 18E.40.060 and FWMC 19.145.260 and 270. Streams in the project area are likely to be considered fish -bearing unless there are steep slopes or drop structures downstream that preclude anadromous fish passage. If anadromous fish cannot . access the site, there still may be resident fish in the project area. A fish survey would be needed to evaluate the use of this reach by fish species, but is not planned since no in -water work is proposed. Streams 1, 2, and 3 are assumed to be fish -bearing streams. Streams 1 and 2 are under thejurisdiction of Pierce County and would be likely considered Type F2 fish -bearing streams, which are perennial, natural waters with a defined bed and bank that support critical fish species and are adjacent to a landslide hazard area (PCC 18E.40.060.B.3). Stream 3 is under City of Federal Wayjurisdiction and would likely be considered a Type F fish -bearing stream, which is a stream that contains fish habitat (FWMC 19.145.260.2). Streams 4 and 5 have steep slopes that likely preclude anadromous fish usage, and Stream 4 goes subterranean for a portion of the channel, leading us to type these streams as non -fish bearing. Streams 4 and 5 are under the jurisdiction of the City of Tacoma outside of the park and Pierce County within the park. Streams 4 and 5 would likely be considered Type Np by Tacoma and Type N1 by Pierce County, which are both non -fish bearing, perennial streams with a defined bed and bank that do not support critical fish species (TMC 13.11.410.1, PCC 18E.40.060.B.3). Stream 6 terminates in Wetland D without the potential for fish presence and in under the jurisdiction of the City of Federal Way. Stream 6 is likely to be a Type Np, perennial non -fish bearing stream (FWMC 19.145.260.2).

Details of these two components are provided below. 3.3.1 Office Methods Office preparation for the delineation consisted of reviewing a variety of online sources, including aerial photographs, the National Wetland Inventory (Figure 6), Pierce County Pubic GIS, King County iMap, Federal Way Critical Areas Map, NRCS Web Soil Survey and soil descriptions, NRCS Agricultural Applied Climate Information System for weather and climate data, WDNR LiDAR Portal, USGS StreamStats, Forest Practices Activity Mapping Tool, etc. Pierce County GIS (Figure 7a) and King County IMAP do not show any wetlands in the project area. The City of Federal Way has a wetland mapped in the eastern portion of the project area (Figure 7b), north of Dash Point Highlands Park. The City of Tacoma has one discrete wetland mapped associated with a stream to the west of the project area and the area encompassing the majority of the southern park extension is described as containing many seeps. 3.3.2 Field Methods The presence of wetlands was evaluated in accordance with Pierce County Code (PCC) 18E.30.020, Federal Way Municipal Code (FWMC) 19.145.410, using the routine approach of the U.S. Army Corps of Engineers (USACE) Wetlands Delineation Manual (Environmental Laboratory, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys and Coast Supplement (Version 2.0) (Supplement) (U.S. Army Corps of Engineers, 2010), and the Washington State Wetlands Identification and Delineation Manual (WDOE 1997). Details of the three -parameter approach are provided in the following sections. 3.3.2.7 Vegetation The existing vegetation was characterized for wetlands and adjacent uplands. Scientific names and indicator status were assigned using the 2016 National Wetland Plant List (Lichvar et al., 2016). A species indicator status refers to the relative frequency with which the species occurs in jurisdictional wetlands. An area satisfies the hydrophytic vegetation criteria when, under normal circumstances, more than 50 percent of the dominant species from each stratum are obligate wetland (OBL), facultative wetland (FACW), or facultative (FAC) species. 3.3.2.2 Soils The presence of hydric soils was determined consistent with the WMVC Regional Supplement and current regulatory guidance. The supplement includes a number of hydric soil indicators specific to this region. Soils were evaluated based on these indicators. 3.3.2.3 Hydrology The presence of wetland hydrology was determined by evaluating a variety of direct and indirect indicators. In addition to direct hydrologic measurements, hydrologic indicators can be used to infer satisfaction of the wetland hydrology criterion. Field indicators of wetland hydrology listed in the Regional Supplement include, but are not limited to, visual observation of inundation or saturation, sediment deposition, hydric soil characteristics, watermarks, drift lines, oxidation around living roots and rhizomes, and water -stained leaves. To satisfy the hydrology criterion for wetlands, soils need to be inundated or saturated to the surface for at least 14 consecutive days during the growing season. The site visits were conducted during the growing season. Eq PBS 7 April 30, 0 19 PBS Project 40525.028 28 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Dash Point State Park Washington State Parks Service Pierce County, Washington 3.3.2.4 Rationale for Use of the Routine Delineation Methods Based upon guidance provided in the Corps of Engineers Wetland Delineation Manual (1987 Manual) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual., Western Mountains, Valleys and Coast Supplement (Version 2.0) (WMVC Regional Supplement), it is the best professional judgment of the PBS delineation team that the wetlands in the study area exist under "normal circumstances" as defined in the 1987 Manual and supplement. Therefore, we delineated waters and wetlands using methods recommended in the manual for routine situations. 3.3.2.5 Growing Season The growing season for the site was estimated based on the nearest weather station with sufficient data to provide an estimate of dates for 50 percent probability of air temperatures of 28' Fahrenheit (7) or higher (USACE, 2010). Using this approximation and data from the NRCS Climate Analysis for Wetlands Tables (WETS Tables, NRCS 2018b), the growing season in this region would be approximately 298 days long. Generally, this translates to the period from February 6th through December 1st. To meet the hydrology criteria at this site, soils would need to be saturated to the surface for at least 14 consecutive days during that interval. All delineation site visits occurred during the estimated growing season. 3.3.2.6 Climate The region has a predominantly temperate marine climate with warm, dry summers and mild, wet winters, typical of much of the Puget Sound area. The property is in the Puget Sound lowlands climatic region. Mean high temperatures for the Tacoma No. 1 Station (4.5 miles SSE) range from 47°F in December to 77°F in August. Mean low temperatures range from 36°F in December and January to 56°F in July and August (AgACIS For King County 1983-2018). The wetland delineation occurred between June 5 and 20, 2018. The rainfall for the month prior to field visits was below average, but the 3 month period preceding the delineations was considered normal. Precipitation levels are considered normal when the probability of that rainfall amount for a given month is greater than or equal to 30% either side of the mean, as displayed in the table below (Table 3).

Ten wetlands (A-H) were identified, and the boundaries were delineated using the three -parameter approach as required in the WMVC Regional Supplement, and formal data plots were recorded at typical locations. Wetland boundaries and data plot locations were flagged in the field with brightly colored plastic tape or pin flags, and wetland flags and data plots were recorded using a Trimble handheld GPS unit with post -processing and sub -meter accuracy. Photographs were taken with a cell phone camera and locations were geotagged with the phone's GPS or referenced to positions PBS 8 April 52.028 �'�V PBS Project40525.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Dash Point State Park Washington State Parks Service Pierce County, Washington collected with the handheld GPS unit. Wetlands A, B, and C were later surveyed by a professional surveyor due to their proximity to the active work areas. Figures 5a-e show the wetland boundaries and location of data plots. Wetland delineation datasheets are included as Appendix A and Wetland Rating Forms are included as Appendix B. Detailed maps showing the individual flag locations for the work area are provided in Appendix C. 3.3.3.7 Wetland A Wetland A is a small (approximately 0.14 acre) palustrine scrub -shrub slope wetland. It occupies a steep slope to the northeast of the confluence of Streams 1 and 2. The location is shown on Figure 5a, and Photos 19 and 20 illustrate the site conditions. The boundary for Wetland A was delineated based on distinct breaks in the plant community, elevation, soil type, and the presence/absence of wetland hydrology indicators. Vegetation The dominant species in Wetland A are salmonberry (Rubus spectabilis, FAC), western touch-me-not (Impatiens noli-tangere, FACW), western lady fern (Athyrium cyclosorum, FAC), and small enchanter's - nightshade (Circaea alpino, FAC). Other species present include piggyback -plant (Tolmieo menziesii, FAC) and water parsley (Oenanthe sarmentosa, OBL). More than 50 percent of the dominant species are FAC or wetter, which satisfies the hydrophytic vegetation criterion. Soils Soils mapped for the area are Ragnar sandy loam, 0 to 6 percent slopes. Soil observed in the sample plot is a black (10YR 2/1) silt loam extending from the surface to approximately 11 inches below the ground surface (BGS). The soil below 11 inches extending to 16 inches below ground surface is composed of a very dark grayish brown (2.5YR 3/1) loamy sand. A hydrogen sulfide odor (A4) was noted in the soil profile (A4). The presence of a hydrogen sulfide odor in the sample plot satisfies the hydric soil criterion. Hydrology Soils in Wetland A were saturated at the surface (A3) and the water table was observed at approximately 6 inches BGS (A2). A hydrogen sulfide odor was also observed in the sample plot (Cl). The presence of these indicators satisfies the wetland hydrology criterion. Upland Associated uplands north of Wetland A were dominated by upland species (notably big -leaf maple and pineland sword fern) had higher chroma soils that do not meet the wetland soils criterion and lacked indicators of wetland hydrology in the upper 18 inches of the sample plot. 3.3.3.2 Wetlands 8-C Wetlands B and C were originally evaluated and surveyed as independent wetlands and late combined based on the Washington State Department of Ecology Rating criteria, which rates wetlands collectively if they are separated by a stream less than 17 feet wide. The combined Wetland B-C is a small (approximately 0.49 acre) palustrine scrub -shrub and emergent slope wetland. It occupies the steep slopes on either side of Stream 2 (Figure 5b). All of Wetland C and the majority of Wetland B are within unincorporated Pierce County. However, a small portion of Wetland B is in the City of Federal Way (King County). Photos 21-24 illustrate the site conditions. The boundary for Wetland B-C was delineated based on distinct breaks in the plant community, elevation, soil type, and the presence/absence of wetland hydrology indicators. Vegetation Dominant vegetation in Wetland B-C includes salmonberry, devil's club (Oploponax horridus, FAC), pineland sword fern, and little western bittercress (Cardamine oligosperma, FAC). Other species present include red elder (Sambucus racemoso, FACU) and California dewberry (Rubus ursinus, FACU). Vegetation along the PB® 9April30, .019 28 ieqPBS Project 405250 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Dash Point State Park Washington State Parks Service Pierce County, Washington stream edge including skunk cabbage (Lysichiton americonus, OBL), water parsley (Oenonthe sormentosa, OBL), and piggy -back plant (Tolmiea menziesii, FAC). More than 50 percent of the dominant species are FAC or wetter, which satisfies the hydrophytic vegetation criterion. Soils Soils mapped for the area are Alderwood gravelly, sandy loam, 8 to 15 percent slopes. Soil in Plot B1 W consist of a very dark brown (10YR 2/2) loam that extends from the surface to a depth of 2.5 inches BGS, overlying a dark gray (2.5Y 4/2) loamy sand with approximately 25 percent distinct, dark yellowish brown (10YR 4/4 to 10YR 4/6) redoximorphic concentrations in the matrix (Al 1). This stratum extends to a depth of approximately 10 inches BGS. The soil from 10 to 15 inches BGS consist of a black (10YR 2/1) silt loam overlying an olive gray (5Y 4/2) loamy sand (15 to 18 inches BGS) with approximately 15 percent distinct olive gray (2.5Y 4/3) redox concentrations in the matrix. A hydrogen sulfide odor (A4) was noted at approximately 10 inches BGS. The sample on the west side of the wetland (Plot C1 W) consisted of very dark grayish brown (10YR2/2) sandy loam with approximately 15 percent distinct, dark yellowish brown (10YR4/4) concentrations (F6), overlying a layers of very dark grayish brown (10YR3/2) to very dark brown (10YR 2/2) sandy loam. A sulfidic odor was present at approximately 12 inches (A4). The presence of the A4, Al 1, and F6 indicator satisfies the hydric soil criterion. Hydrology Soils in Wetland B-C were saturated either at approximately 2 inches BGS or at the surface (A3) and the water table was observed between 7 and 9 inches BGS (A2). A hydrogen sulfide odor (Cl) was also observed in both sample plots. The presence of these indicators satisfies the wetland hydrology criterion. Upland Associated uplands to the east and west of Wetland B-C (Plots B1 U and C1 U) were dominated by upland species (notably western hemlock [Tsugo heterophylla, FACU] and pineland sword fern); had higher chroma color soils that do not meet the wetland soils criterion; and lacked indicators of wetland hydrology in the sample plot. 3.3.3.3 Wetland D Wetland D is a relatively large (approximately 9 acres) palustrine forested and scrub -shrub slope wetland that occupies gently sloping depression between Stream 6 into Stream 3. Wetland D is entirely within the City of Federal Way, Washington. The location of this wetland is shown on figure 5c, and Photos 25-26 illustrate the site conditions. The boundary for Wetland D was delineated based on distinct breaks in the plant community, soil type, and the presence/absence of wetland hydrology indicators. Vegetation Dominant species present in the wetland sample plot (D1 W) include bitter cherry (Prunus emorginata, FACU), common snowberry (Symphoricarpos albus, FACU), salmonberry, Siberian springbeauty (Cloytonia sibirico, FAC), and western lady fern. Other wetland species present in the data plot include Dewey's sedge (Carex deweyana, FAC), fringed willowherb (Epilobium ciliatum, FACW), and piggyback -plant (Tolmiea menziesii, FAC). Areas to the west in Wetland D are dominated by cascara false buckthorn (Frangula purshiana, FAC), Devil's club, giant horsetail (Equisetum telmateia, FACW), Western skunk cabbage, and two - leaf false Solomon's -seal (Maianthemum dilatatum, FAC). More than 50 percent of the dominant species are FAC or wetter, which satisfies the hydrophytic vegetation criterion.

From 14 to 20 inches BGS, the soil consists of a dark yellowish brown (10YR 3/6) loamy sand. A hydrogen sulfide odor (A4) was noted in the soil profile (A4). The presence of a hydrogen sulfide odor in the soil plot satisfies the hydric soil criterion. Hydrology Soils in wetland sample plot D1 W were saturated at the surface (A3) and the water table was observed at 10 inches BGS (A2). A hydrogen sulfide odor was also observed in sample plot (Cl). The presence of these indicators satisfies the wetland hydrology criterion. Upland Associated uplands southeast of Wetland D (Plot D1 U) were dominated by non-hydrophytic species including salal and western swordfern; had higher chroma color soils that do not meet the wetland soils criterion and lacked indicators of wetland hydrology in the sample plot. 3.3.3.4 Wetland E Wetland E is a small (approximately 0.04 acre) palustrine scrub -shrub wetland that occupies a steep slope along Stream 4. The location is shown on Figure 5d, and Photos 27 - 28 illustrate the site conditions.

The three wetlands are located in a series of connected shallow depressions along Stream 5, separated by well-defined rockeries that include concrete and other artificial materials. The locations of Wetland Ga, Gb, and Gc are shown on Figure 5e, and Photos 31-32 illustrate the site conditions. Note that of the three wetland, only Wetland Gc is within the Dash Point State Park - the other two wetlands are located outside of the Park in the City of Tacoma and were delineated only to identify potential buffer impacts. The boundary for Wetlands Ga, Gb, and Gc was delineated based on distinct breaks in the elevation, plant community, soil type, and the presence/absence of wetland hydrology indicators. Vegetation Dominant species present in the wetland data plot (G1 W) include red alder, western red cedar, red elder, salmonberry, climbing nightshade (Solanum dulcamara, FAC), and water horsetail (Equisetum fluviatile, OBL). More than 50 percent of the dominant species are FAC or wetter, which satisfies the hydrophytic vegetation criterion. Soils Soils data is not available digitally for this area.

The site was assessed for Fish and Wildlife Species and Habitat Conservation Areas and habitats of local importance. 4.1 Mapped Habitat The WDFW Priority Habitat and Species maps shows coho (Oncorhynchus kisutch) and surf smelt (Hypomesus pretiosus) in the reach of Stream 1 adjacent to Puget Sound, outside of the project area but in the same drainage system. Coho salmon is a candidate species for federal listing under the Endangered Species Act, but is not listed by the State of Washington as threatened, endangered, sensitive, or species of concern. Surf smelt is not listed as a threatened, endangered, or candidate species by the federal government or by the State of Washington as threatened, endangered, sensitive, or species of concern. Both coho and surf smelt are listed as priority species under Washington State's Priority Habitats and Species list. The entire park is mapped as a Biodiversity Area and Corridor because it is a parkland area within King and Pierce Counties and can provide refugia and dispersal habitat for a range of species. Washington State Department of Fish and Wildlife Salmonscape online mapping show assumed presence of coho salmon, fall Chinook (Oncorhynchus tshawytscha) , winter steelhead (Oncorhynchus mykiss), and pink salmon (Oncorhynchus gorbuscho) in Streams 1, 2 and 3, due a to a lack of a man-made or gradient barriers. Chinook salmon and winter steelhead trout are federally listed as Threatened, but are not listed by Washington State. Pink salmon are not currently listed as threatened, endangered, or candidate species under the federal Endangered Species Act or Washington State's endangered species regulations. Chinook, steelhead, and pink salmon are all listed as priority species by Washington State. 4.2 Habitat Assessment Methodology To determine the presence or absence of regulated fish or wildlife species or habitat in the project areas as described in PCC 18E.040.030.B., we observed dominant habitat features and species present during the site visit. 4.3 Identified Habitat Conservation Areas Species of local importance and their associated habitat include coho salmon, fall Chinook, winter steelhead, and pink salmon in Streams 1, 2, and 3 based on WDFW Salmonscape. Fish and Wildlife Species and Habitat Conservation Areas and habitats of local importance present in the study area included: snag -rich areas and downed logs, waters of the state and/or adjacent riparian -shoreline areas, and wetlands. Dash Point State Park is also considered a Potential Fish and Wildlife Habitat Conservation Area. No individual nests, rookeries, or dens were identified during our field assessment of the study area. 4.4 Existing Vegetation The existing vegetation varied based on topography and hydrology throughout the site. In dry upland areas, between the stream valleys, the overstory consisted of Douglas -fir (Pseudotsugo menziesii), big -leaf maple (Acer macrophyllum), western hemlock (Tsuga heterophylla), and red alder (Alnus rubra). Understory species in the upland forest include western swordfern (Polystichum munitum), salal (Gaultheria shallon), salmonberry (Rubes spectabilis), evergreen huckleberry (Vaccinium ovatum), western bracken fern (Pteridium aquilinum), red elderberry (Sambucus racemoso), Indian plum (Oemlario cerasiformis), low Oregon grape (Mahonia nervosa) false solomon's-seal (Maianthemum racemosum), western trillium (Trillium ovatum) and California blackberry (Rubus ursinus). In the steeply sloped riparian areas vegetation was more sparse, with an overstory consisting of big -leaf maple, Douglas -fir, and hemlock. The riparian understory consisted of beaked hazelnut, oceanspray, western swordfern, red elderberry, low Oregon grape, false solomon's-seal, western trillium, foam flower (Tiarella trifoliata), western maidenhair fern (Adiantum aleuticum), salmonberry, spring beauty PBS April 20 � 15 PBS Project 40S2 5.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Dash Point State Park Washington State Parks Service Pierce County, Washington (Claytonia sibirica) and California blackberry. Wetland vegetation is described in the wetland section of this report. Invasive species had limited coverage in most areas and primarily included Himalayan blackberry (Rubus ormeniacus), cut -leaf evergreen blackberry (Rubus laciniatus), herb Robert (Geranium robertianum), and English holly (Ilex aquifolium). PROJECT DETAILS The Washington State Parks and Recreation Commission (Commission) wishes to replace a footbridge at Dash Point State Park. The existing primary footbridge crosses a stream in a steep walled ravine with unstable slopes and has started to collapse due to soil subsidence. The soil is very sandy and the cement pilings that support the footbridge are sinking into the soil and no longer provide adequate support. The footbridge is now closed to the public. Rather than construct a new footbridge in the same location, the Commission has identified a site further downstream where slope conditions are more favorable. A geotechnical evaluation has been performed to determine the optimal location for a new footbridge. The trail will be relocated to the new footbridge location and the existing trail will be blocked off and revegetated. The portion of the park where most of the work will occur is in unincorporated Pierce County, however portions of the trail realignment and access are within the City of Federal Way. We have prepared this report based on federal, Washington State, Pierce County and City of Federal Way regulations to include an assessment of footbridge locations (two existing, one new), the new trail corridor, any potential construction access or staging locations and the surrounding 315 feet from all of these areas. The following permits and submittals are anticipated to be required for the project: Federal • No work is proposed in wetlands or below Ordinary High Water Mark of the streams and so we do not anticipate the need for a US Army Corps of Engineers (USACE) permit at this time. Washington State • Parks will prepare an internal SEPA review for the project. • A Hydraulic Project Approval (HPA) from Washington Department of Fish & Wildlife (WDFW) Local Governments Pierce County Anticipated Pierce County permits include: • A Critical Areas permit; and • A building permit for demolition of the existing footbridge and construction of the new footbridge. • Pierce County has confirmed that a Land Use permit will not be required. City_of Federal Way Additional permits required for the City of Federal Way include: • A Master Land Use Application; • A Process I Development Application; and • A Project Narrative. The majority of the clearing and grading associated with the project will be completed in the dry season between May 1 and October 1 in accordance with PCMC 18E.40.040.B.1.a. Final grading for the pedestrian bridge, some portions of the proposed trail, trail closure areas, and mitigation plantings will be completed PBS 16 April 52 .0 8 PBS Project 40525.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Washington State Parks Service Dash Point State Park Pierce County, Washington after October 1st. However, these areas will be stabilized when not being actively worked, and Temporary Erosion and Sediment Control (TESC) measures will be implemented to prevent runoff from entering streams. No instream structures are proposed as part of this project. The new footbridge will span the stream channel and allow for uninterrupted downstream movement of wood and gravel and pass the base flood flows. A WDFW representative performed a preliminary site visit on May 10, 2018 and provided suggestions for Best Management Practices to be used during the project. These recommendations along with recommendations from the project engineers have been compiled below. 5.1 Project Components and Best Management Practices 5.1.1 Bridge Removals The primary footbridge removal will occur in the upstream reach of Stream 1. The footbridge is 36 feet long with stairs on each bank that lead up to mirroring wood platforms' the combined length of the structures is 65 feet. A wood walkway extends to the existing dirt trail on the east side of the footbridge. The wood platforms and walkway comprised 412 square feet of area. A second, smaller footbridge crosses Stream 2 and is also proposed for removal. The smaller footbridge is in disrepair and serves only to enable pedestrians to access the larger, failing pedestrian bridge. Closing and removing the smaller footbridge will help ensure that the existing trail will no longer be useable. The smaller footbridge is 16.5 feet long and is supported by a crib wall on the west stream bank. The Commission anticipates that the large footbridge will be able to be lifted out of its current position using a pony winch. The hand rails and decking will first be removed in place and then a pony winch would be used to lift the deck up with cables and then slide it onto one bank. If needed, the winch will be attached to adjacent trees using tree protection approved by the WSPRC arborists. Tarps or netting should be suspended below the footbridge deck to catch any falling material, including sawdust from treated wood. Tarps could be staked in and stretched across the channel. No materials are to enter the channel and if an incident does occur, the contractor will be instructed to contact a parks representative immediately and prior to material removal. Treated wood will be removed in whole pieces to avoid saw dust potential. No materials will be burned on -site. WDFW would like to see minimal bank disturbance and stabilization after disturbance. The concrete filled culverts will be lifted or dragged up the bank, parallel with the slope, also using the winch to minimize bank disturbance. Bank stabilization will include geotextile fabric (e.g. coconut matting) and rolled geotextile matting to act as a wattle. Contractors will use the existing trails to drag any materials through the area already disturbed (devoid of vegetation) by viewing platforms. The small footbridge will be removed in whole pieces and transported off site using existing trails. The fill and crib wall on the west bank will be removed and the soil used to regrade trail upslope that has eroded. The soil will be removed first, while the cribwall is still in place, to prevent any materials from entering the stream. Stabilization and revegetation of these areas is described in the Mitigation section of this report. 5.1.2 Proposed Trail Due to the closure of the large pedestrian bridge, park users have established a new unsanctioned social trail to the north that crosses the stream approximately where the new footbridge is proposed. An EarthCorps trail designer, assessed the user trail and developed a new trail alignment to enable access to the proposed footbridge (EarthCorps, 2016). The existing user social trail is non -linear with many tripping hazards and is not ideal for permanent use. The Commission proposed to realign the trail as proposed by EarthCorps, while using as much of the existing user social trail as practicable. The new trail will be approximately 960 feet long (including the footbridge) and 3 feet wide, as shown on Sheets 2-4 and 5. One -hundred and forty (140) square ON PBS April 30, 0 �. 17 PBS Project40525.02828 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Dash Point State Park Washington State Parks Service Pierce County, Washington feet of the new trail will be within the buffer for Wetland B-C and 1,990 square feet will be in the buffers for Streams 1 and 2. No portion of the trail will directly impact the adjacent wetland or stream. Any trees felled during construction will remain in place to provide habitat, and abandoned sections of the current user social trail are proposed for replanting, as described in the Mitigation section of this report. 5.1.3 Proposed Footbridge The proposed replacement footbridge will be located downstream from the existing footbridge in an area with lower valley walls and more stable soils, as described in the Geotechnical Report (GeoEngineers, 2016). The footbridge will cross Stream 1 just upstream from Wetland B-C (Sheet 2, 3). The footbridge will be 40 feet long and 5 feet wide. It will be supported on either side by concrete footings. The anticipated footprint on the footbridge supports is 38 square feet (combined). All work and impacts will be above the Ordinary High Water Mark (OHWM). The new footbridge will be built in components using manual labor and the materials will be delivered to the site by hand -carrying or a using motorized wheelbarrow. The new trail will be built prior to the construction of the footbridge and used for construction access. Component members will be bolted together and ropes will be used to slide assembled footbridge supports over the channel. To prevent increased turbidity from foot traffic in the stream during construction, planks or pieces of plywood will be used as temporary crossing structures. These crossing structures will be temporary and installed above the OHWM, if possible. Temporary crossing structures are permitted to be installed below OHWM within the WDFW fish window (approximately June 15 through Sept 30). The WSPRC arborist identified a big -leaf maple and an alder as hazard trees on the west bank, adjacent to the proposed footbridge site. WDFW suggested felling these hazard trees into the stream downstream of the new footbridge location to provide habitat and retain sediment in place, thereby preventing further channel incision. WSPRC is concerned about creating stream channel migration issues by felling trees into the stream. As a result, the felled trees will be relocated to key junctions with the abandoned trail, where they will provide habitat and deter access by trail users. 5.1.4 Construction Access To remove materials from the existing pedestrian bridge and bring in materials for the proposed footbridge and mitigation, the Commission has identified two potential access areas; one from the east and one from the west. When accessing the site from the west, using the Old Boundary Trail, there are 3 waters/wetland crossings. A wooden footbridge crosses Stream 5 and Wetland Gb/Gc. The railings of this footbridge could be removed, and plates placed on the footbridge deck to protect the footbridge during construction. There is a raised soil crossing over two small (6") PVC culverts, which connect Wetland F on either side of the trail. This crossing could be protected by temporary metal plates or plywood. The third crossing is over Stream 4, downstream from Wetland E. It consists of a raised dirt path over a corrugated steel culvert that is three feet in diameter and partially blocked with sediment. This crossing could also be protected using temporary metal plates or plywood. The length of trail to access the existing large pedestrian footbridge from the west is 663 linear feet. When accessing the site from the east, the trail begins in a Dash Point Highlands Park (Federal Way) and after entering DPSP one would turn left onto the Boundary Trail, cross the small footbridge proposed for removal, and then arrive at the existing large pedestrian footbridge and viewing platforms. This access route passes near Stream 6 and Wetland D but does not cross either feature. The only crossing is of Stream 2 at the existing small footbridge. The length of trail to access the existing large pedestrian footbridge from the east is 506 linear feet. IMPPBS April 52 0 18 PBS Project 405.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Dash Point State Park Washington State Parks Service Pierce County, Washington No impacts to critical areas or their buffers are anticipated with either access route. 5.2 Project Chronology and Schedule All clearing activities and the majority of the soil disturbance/trail construction/demolition work is proposed to take place between May 151 and October 151. Parks is proposing the removal of the identified trees in August/September and rough grading of the trail is proposed for May -June. Parks is proposing the removal of two existing footbridges by a Contractor and the installation of a premanufactured footbridge by a Contractor between June and August (estimated). Final grading for the pedestrian bridge and proposed trail, trail closure, and mitigation plantings may be completed after October 111. Once the pedestrian bridge is installed, final grading of new trail (estimated September/October) will be established and replanting of the trails to be decommissioned (November through February). All disturbed areas including the decommissioned trails will be restored with native plant species by June 2021. 5.3 Proposed Impacts The proposed footbridge replacement and trail realignment does not include in -water work, but does include impacts to Pierce County regulated buffers for Wetland B-C and Streams 1 and 2. The proposed project does not affect regulated wetland and stream buffers in the City of Federal Way. The removal of the existing, failing footbridge, new bridge and footings, and realigned trails will result in approximately 805 square feet of permanent buffer impact and 1,325 square feet of temporary buffer impact (2,130 square feet combined). Native tree and shrub vegetation within the new trail areas will be removed during the trail realignment and footbridge construction due to unavoidable root zone impacts or hazardous conditions. The vegetation to be cleared includes a total of ten trees (3 red alder, 5 bigleaf maples, and 2 Douglas firs), which includes the hazard trees previously mentioned. Of the10 trees, all but two red alders are within -wetland and stream buffers. Following the removal of the existing footbridge, installation of the new footbridge, and realignment of the foot trails, disturbed areas will be revegetated with native woody vegetation. The revegetated area includes the 1,325 feet of temporary impact, and totals 4,631 square feet of planting. This results in an overall increase in vegetated buffer of 2,500 square feet when compared to the 2,130 square feet of impact. 5.4 Project Compliance with Fish and Wildlife Conservation Standards The proposed footbridge replacement and trail realignment does not include in -water work, but does include work in wetland and stream buffers that are regulated by Pierce County. The project improvements have been designed in accordance with PCC 18E.40.040 B standard& as identified in Table 5 (below).

Final grading for the pedestrian bridge and proposed trail, trail closure, and mitigation plantings will be completed after October 1st. Once the pedestrian bridge is installed, EarthCorps will return for final grading of new trail (estimated September/October) and replanting of the trails to be abandoned (November -February). All disturbed areas including the decommissioned trails will be restored with native plant species. Best management practices will be used to prevent erosion in all construction areas. These will include installing biodegradable wattles or coir fabric logs, compost, and erosion control fabric on the steep slopes by the footbridge removal and installation sites. The trails are narrow, bare earth pedestrian trails and are not anticipated to result in an increase in erosion. If needed, water bars or equivalent trail protection measures may be installed as part of routine maintenance. For final grading that takes place after October 1, additional TESC measures will be implemented to ensure that the exposed areas are stabilized and do not result in runoff to wetland or streams. The project will submit for applicable permits as required by Pierce County, The realigned foot path will be on the surface of the native soil and will require minimal grading. Compaction will be limited on the site by minimizing the use of powered or heavy equipment. Soil in decommissioned trail areas will broken up and planted with native shrub vegetation appropriate to the site. These measures will minimize loss of soil moisture. i PBS April 30, 2019 20 PBS Project 40525.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Washington State Parks Service Standard le.

The new footbridge will not interrupt downstream movement of wood and gravel. The proposed project includes mitigation for the affected buffer areas. The proposed project does not include a road bridge. The trail will be composed of pervious native earth. Me 22 April 30, 2019 PBS Project 4052S.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Washington State Parks Service 6 MITIGATION MEASURES Dash Point State Park Pierce County, Washington Streambank stabilization surrounding the footbridge removal and construction sites will be achieved through soft armoring of the banks with coir orjute matting, interrupted by rolled coir orjute wattles. Planted vegetation will be native and historically indigenous to the site. Any compacted soils will be broken up or aerated prior to planting. Plants will be installed through the matting to stabilize and revegetate the slopes. In areas that do not require matting to stabilize the slopes, planting areas may be mulched following plant installation to provide nutrients, retain soil moisture, and reduce competition by weeds. 6.1 Zones of Mitigation Table 6 outlines the proposed planting zones for the trail revegetation areas (Zone A) and slopes near the footbridge removal and replacement areas (Zone B). Control of weeds will be limited to those species listed on the state noxious weed list. Native volunteers will be retained if desirable. Table 6.

The monitoring will include a baseline monitoring, yearly monitoring in years 1, 2, and 3 and a final monitoring in Year 5. Monitoring may need to be continued if performance standards are not being met. When planting is complete, a Baseline Monitoring Report will be submitted to the County that includes an as -built drawing and a more detailed Monitoring Plan. The as -built report will document that the specified planting has been completed. Specific monitoring protocol will be provided in the Baseline Monitoring Report. Once approved by the County, this plan will form the basis for evaluating the success of the critical area plantings. 6.3 Performance Standards Table 7 shows the performance standards that will be used to measure mitigation success. These standards have been developed to account for the unique conditions and constraints of the site. Table 7.

All planted stock mortality in the first year will be replaced either in -kind or with a replacement species approved by the project biologist. Some species may be replaced if not well adapted to the site. Any replacement plantings will occur either in the fall or spring. If erosion is occurring at the footbridge sites, it may be necessary to install corrective measures such as: biodegradable erosion control materials, organic mulch, live stake plantings, or other best management practices. 7 CONCLUSIONS Ten wetlands (Wetland A, B-C, D, E, F, Ga, Gb, Gc, and H) were identified in the study area. These wetlands range in size from less than one acre to over 9 acres. Cowardin classes represented include palustrine forested, scrub -shrub, and emergent habitat types. Five of the ten wetlands are slope systems, four are riverine, and one is depressional. Wetlands A, F, and H are entirely within Pierce County. Wetland B-C crosses the boundary between unincorporated Pierce County and the City of Federal Way, and Wetland D is entirely within the City of Federal Way. Wetlands Ga and Gb are entirely within the City of Tacoma, and Wetlands E and Gc span the boundary between the City of Tacoma and unincorporated Pierce County. Based on the preliminary ratings, Wetlands E, WE PBS April 52 .019 28 ,,�`�, 24 PBS Project 40525.028 Fish and Wildlife Habitat Assessment Study & Wetland Analysis Report Dash Point State Park Washington State Parks Service Pierce County, Washington Ga, Gb, and Gc are a Category III wetland and Wetlands A, B/C, D, F, and H are all Category IV wetlands. None of the identified wetlands are within proposed work areas. Wetland buffers were determined using either the Pierce County Code 18E.30.060 standard buffers with adjustments for land use intensity per 18E.30.070 - Appendix F, the City of Federal Way Revised Code 19.145.420, or the City of Tacoma Revised Code 13.11.320. In general, the buffer widths vary from 25 feet to 75 feet, depending on the wetland category and applicable regulations. Six streams were also identified in the study area. Streams 1 and 2 are entirely within Pierce County, are fish bearing perennial streams (Type F2), and have a standard buffer width of 150-feet. Within the study area, Streams 4 and 5 are partially within Pierce County and partially in the City of Tacoma. Streams 4 and 5 are perennial, non -fish bearing streams located within'/4 mile of the confluence with a Type F1 or F2 water and would be typed as Type N1 in Pierce County, with a 115 foot buffer. In the City of Tacoma, Streams 4 and 5 are considered Type Np, and have a 100 foot buffer. Streams 3 and 6 are located in the City of Federal Way. Stream 3 is a is a perennial, fish bearing stream (Type F) with a 100 foot buffer. Stream 6 is a non -fish bearing perennial stream (Type Np), and has a 50 foot buffer. No other threatened, endangered, candidate, or locally significant species or habitats were observed on the site or nearby. The proposed project will affect wetland and stream buffers within Pierce County, but does not affect wetlands, streams, or buffers within the City of Federal Way. The proposed pedestrian improvements have been designed to minimize potential environmental impacts. The project does not include work within streams or wetlands, and is not expected to result in any permanent or temporary loss of wetland or stream area or habitat function. The proposed improvement will result in permanent impacts to wetland and stream buffers in Pierce County, but the trail realignment will result in a net gain of vegetated buffer area. The project will not affect buffers in the City of Federal Way. No logs, snags, or other habitat features that do not represent a safety hazard will be removed, and any felled wood will be retained in the park. Areas of temporary disturbance and abandoned trail areas will be revegetated to provide habitat and deter casual intrusion by park visitors. 8 DISCLAIMER This report is based on observations of vegetation, soils, and hydrology at the time of the study.

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? 0 NO - go to 2 ❑ 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. 0 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 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 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). 0 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? 0 The wetland is on a slope (slope can be very gradual ), 0 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. 0 The water leaves the wetland without being impounded. ❑ NO - go to 5 0 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). 5. 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. 0 NO-goto6 ❑ YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 WSDOT Adapted Form - January 14, 2015 Wetland name or number A 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, Ypresent, is higher than the interior of the wetland. 0 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. 0 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 being rated HGM class to use in rating Riverine Slope + Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE if you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a j unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1 - 7 apply, and go I to Question 8. _ _ 1. Are the water levels in the entire unit usually controlled by tides except during floods? NO - go to 2 ❑ 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. 0 NO - go to 3 ❑ YES - The wetland class is Flats if your wetland can be classified as a Flats wetland, use the form for Depression/ 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 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). 0 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), p 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. 0 The water leaves the wetland without being impounded. ❑ NO - go to 5 0 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). 5. 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. 0 NO-goto6 ❑ YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 WSDOT Adapted Form - January 14, 2015 Wetland name or number B/C 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, ifpresent, is higher than the interior of the wetland. 0 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. 0 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 within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE if you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If 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. T 1. Are the water levels in the entire unit usually controlled by tides except during floods? 0 NO - go to 2 ❑ 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. 0 NO - go to 3 ❑ YES - The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for ❑epressional 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 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). 0 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? 0 The wetland is on a slope (slope can be verygradual), p 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. 0 The water leaves the wetland without being impounded. ❑ NO - go to 5 0 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). 5. 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. 0 NO-goto6 ❑ YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 WSDOT Adapted Form - January 14, 2015 Wetland name or number D 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. 0 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. 0 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 within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE lfyou 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.

If 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? 0 NO - go to 2 ❑ 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. 0 NO - go to 3 ❑ YES - The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depression/ 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 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). 0 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. 0 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). 5. Does the entire wetland unit meet all of the following criteria? 0 The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, 0 The overbank flooding occurs at least once every 2 years. ❑ NO-goto6 0 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 WSDOT Adapted Form - January 14, 2015 Wetland name or number E 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. 0 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. 0 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 within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE lfyou are still unable to determine which of the above ciire ila apply to your wetland, or ifyou have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

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? IZ NO - go to 2 ❑ 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 If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is 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. 10 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 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 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). 12 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 very gradual), o 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. o The water leaves the wetland without being impounded. ❑ NO-goto5 21 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). 5. 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. NO-goto6 ❑ YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 WSDOT Adapted Form - March 2, 2015 Wetland name or number F 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. ❑ NO - go to 7 El 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. Q 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 being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If 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? 0 NO - go to 2 ❑ 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. 0 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 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 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). 0 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 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. 0 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). 5. Does the entire wetland unit meet all of the following criteria? 0 The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, 0 The overbank flooding occurs at least once every 2 years. ❑ NO-goto6 0 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. 0 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. 0 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 I use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE lfyou are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If 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? 0 NO - go to 2 ❑ 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. 0 NO - go to 3 ❑ YES - The wetland class is Flats If your wetland can be classified as a Flats wetland, use the form for Depression/ 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 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). 0 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. 0 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). 5. Does the entire wetland unit meet all of the following criteria? p The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, 0 The overbank flooding occurs at least once every 2 years. ❑ NO-goto6 0 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. 0 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. 0 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.

Groundwater and surface water runoff are NOT sources of water to the unit. 0 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 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 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). 0 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. 0 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). 5. Does the entire wetland unit meet all of the following criteria? 0 The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, 0 The overbank flooding occurs at least once every 2 years. ❑ NO-goto6 0 YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding.

Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. 0 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. 0 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 being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE lfyou are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

If 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? 0 NO - go to 2 ❑ 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 lfyour 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. 0 NO - go to 3 ❑ YES - The wetland class is Flats if your wetland can be classified as a Flats wetland, use the form for Depression/ 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 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). 0 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? 0 The wetland is on a slope (slope can be very gradual ), p 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. 0 The water leaves the wetland without being impounded. ❑ NO - go to 5 0 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). 5. 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. 0 NO-goto6 ❑ YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 WSDOT Adapted Form - January 14, 2015 Wetland name or number H 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. 0 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. 0 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 within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE if you are still unable to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

The footbridge is now closed to the public —The failing footbridge crosses a potentially fish -bearing stream in a steep walled ravine with unstable slopes and has started to collapse. There are wood platforms and stairs adjacent to the footbridge that cover approximately 415 square feet. The existing wood platforms and stairs will be removed and the access trail for the failing footbridge will be abandoned; all disturbed or abandoned areas will be restored to native vegetation. A replacement footbridge is proposed at a site approximately 500 feet downstream , where slope conditions are more stable and users have established an unsanctioned trail and stream crossing. The new footbridge will be 40 feet long and 5 feet wide and require new concrete footers. The proposed trail will be relocated to provide access the new footbridge location and a second, smaller footbridge (17 feet long) will be removed as part of the trail realignment. All proposed work will occur above the Ordinary High Water Mark (OHWM) of associated streams. All of the footbridge work and a majority of the new trail alignment will occur in unincorporated Pierce County. PROVISIONS TIMING - PLANS - INVASIVE SPECIES CONTROL 1.

The existing primary footbridge has started to fail and is closed to the public. The Commission performed a geotechnical evaluation to determine the optimal location for a new footbridge; the new footbridge is proposed to be installed downstream of the failing footbridge. A proposed trail (960 feet long, 3 to 4 feet wide) will be developed in the location of an existing unsanctioned trail. Please see attached Plans. Construction Stormwater Pollution Prevention Plan SWPPP The 13 BMP Elements A Stormwater Pollution Prevention Plan (SWPPP) includes the 13 elements of a Construction SWPPP as detailed in the following subsections below, from Volume II of the Department of Ecology Stormwater Management Manual for Western Washington (Stormwater Manual). The following section briefly describes the 13 elements and the Best Management Practices (BMPs) anticipated for use in the project. Element #1: Preserve Vegetation/Mark Clearing Limits The limits of construction, trees and natural vegetation that are to be preserved within the construction area are delineated on the plans. Duff layer, native top soil and natural vegetation shall be preserved to the greatest extent possible. The BMPs relevant to element #1 that will be applied for this project include: - BMP C101: Preserving Natural Vegetation Element #2: Establish Construction Access Construction access will be limited to two access and exit routes (as identified on Sheet 5 of the Plans). The BMPs relevant to construction access that will be utilized are: - BMP C107: Construction Road / Parking Area Stabilization Import of haul material shall occur through the two construction access areas to the site, as identified on the Plans. The construction equipment that enters the site must be checked to ensure that there are no vehicular or mechanical fluid leaks that could contaminate the soils. Access points will be stabilized with a pad of crushed rock to minimize tracking on sediment onto public roads. If sediment is tracked off site, clean the affected roadway(s) thoroughly at the end of each day, or more frequently as necessary. Element #3: Control Flow Rates To protect waterways downstream of the project site from stormwater runoff, wattles will be utilized as shown on the Plans (Sheets 3-4). The specific BMPs for flow control to be used are: , - BMP C235: Wattles The project does not result in an increase to impervious area, and therefore will not alter runoff flow rates. Element #4: Install Sediment Controls All stormwater runoff from disturbed areas shall pass through a sediment removal BMP prior to leaving the construction site. The specific BMPs to be used for controlling sediment on this project include: - BMP C235: Wattles Straw wattles are to be placed above ordinary high water (OHW) in the stream prior to any construction or demolition activities to protect the stream (see Sheet 3-4 on the Plans). Element #5: Stabilize Soils Exposed and unworked soils shall be stabilized through the application of effective BMPs that prevent erosion. The specific BMPs for soil stabilization that shall be used on this project include: BMP C122: Nets and Blankets - BMP C235: Wattles A biodegradable erosion control blanket following WSDOT Standard Specification 9-14.5(2)B is proposed to be placed in the location of the primary (65 feet long) footbridge to be removed. The erosion control blanket is proposed to be secured using biodegradable stakes, and coir logs placed to stabilize the slopes. Native vegetation is proposed to be planted through the biodegradable blanket to provide long term slope stabilization. No soils shall remain exposed and unworked for more than seven days during the dry season (May 1 to September 30) and two days during the wet season (October 1 to April 30), unless otherwise specified on the Plans. All soils shall be stabilized at the end of the shift before a holiday or weekend if needed based on weather forecasts. Page 2 of 5 Element #6: Protect Slopes All cut and fill slopes will be designed, constructed, and protected in a manner that minimizes erosion; cut and fill slopes will be stabilized as soon as possible. Loose material will be placed on the uphill side of the constructed trail area, with consideration for safety and space. The following specific BMPs will be used to protect slopes for this project: BMP C122: Nets and Blankets - BMP C235: Wattles Where 2:1 back slope is not attainable along the proposed trail, an erosion control blanket is to be installed per WSDOT Standard Specification 9-14.5(2)B, biodegradable erosion control blanket for slopes steeper than 3:1 (H:V), see Plans Sheet 21-25. The trail will be constructed with a cut/fill balance approach; the anticipated amount of cut is (310 cubic yards), which is anticipated to be reused as fill on the trail. Final grading of the trail will incorporate trail surface stabilizing material (gravel, crushed surfacing top course), approximately 50 cubic yards of material is anticipated to be imported to the site. Any exported soils will be required to be disposed of in an approved facility, Subtitle D Landfill. Element #7: Protect Drain Inlets All storm drain inlets shall be protected so that stormwater runoff does not enter the conveyance system without first being filtered to remove sediment. The following specific BMPs will be used to protect existing drain inlets (as needed): - BMP C107: Construction Road / Parking Area Stabilization All approach roads will be kept clean. Contractor to prevent sediment and street wash water from entering storm drains. Storm drains inlets to be protected (using storm drain inlet covers) as needed. Element # S: Stabilize Channels and Outlets Provide stabilization adequate to prevent erosion of stream banks and slopes. - BMP C122: Nets and Blankets A biodegradable erosion control blanket following WSDOT Standard Specification 9-14.5(2)B is proposed to be placed in the location of the primary (65 feet long) footbridge to be removed. The erosion control blanket is proposed to be secured using biodegradable stakes, and coir logs placed to stabilize the slopes. Native vegetation is proposed to be planted through the biodegradable blanket to provide long term slope stabilization. Element #9: Control Pollutants All pollutants, including waste materials and demolition debris that occur onsite shall be handled and disposed of in a manner that does not cause contamination of stormwater. Preventative measures will be taken to ensure that the site will be kept clean, well -organized, and free of debris. Page 3 of 5 Vehicles and construction equipment: - All vehicles will be inspected regularly to detect and leaks or spills, and to identify maintenance needs to prevent leaks or spills. Existing Primary Footbridge Demolition (see Sheet 9 of Plans): A tarp or plastic liner shall be suspended beneath the footbridge during demolition to catch any falling debris. - Treated wood to be removed in whole pieces to avoid saw -dust potential Element #10: Control Dewatering This project work does not require dewatering for construction. Element #11: Maintain BMPs All temporary and permanent erosion and sediment control BMPs shall be maintained as needed to assure continued performance of their intended function. Maintenance and repair shall be conducted in accordance with each particular BMP specification as listed in the Stormwater Manual. All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization is achieved or after the temporary BMPs are no longer needed. Wattles installed above OHW, along the creek bed to remain in place until planting is completed. Planting shown on Sheets 28-31 of the Plans. Element #12: Manage the Project The project manager must ensure that the project is built in such a way to comply with the Construction SWPPP elements. Considerations are: Construction Phasing - BMP C162: Scheduling All clearing activities and the majority of the soil disturbance/trail construction/demolition work is proposed to take place during the dry season May 1st thru September 301h. Therefore, the Commission is proposing the following activities to take place during the dry season: - Rough grading of the proposed trail Installation of the proposed pedestrian bridge Final grading of the proposed trail Demolition/removal of existing footbridges (#1 & #2) Installation of final trail elements along the proposed trail and measures to close the existing trail may take place after October 1s'. Planting of the trails to be decommissioned is proposed to take place November thru February. Page 4 of 5 L Sequencing of construction - The construction of this project is being sequenced to the extent practicable to prevent soil erosion and reduce transport of sediment from the site during construction. - Disturbed areas will be revegetated in a timely manner. - Coordination with other Jurisdictions: Parks will coordinate with the local jurisdictions (Pierce County and City of Federal Way) for construction of this project. Inspection The Commission will require the Contractor to have an Certified Erosion and Sediment Control Lead (CESCL) onsite during soil disturbing activities. - BMP C160: Certified Erosion and Sediment Control Lead The designated person shall be responsible for ensuring compliance with all local, state, and federal erosion and sediment control and water quality requirements. - Maintaining an Updated Construction SWPPP o The SWPPP shall be modified by the CESCL whenever there is a change in the construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutant to waters of the state o The SWPPP shall be modified by the CESCL if during inspections or investigations conducted by the owner/operator, or the applicable local or state regulatory authority, it is determined that the SWPPP is in effective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. The SWPPP shall be modified as necessary to include additional or modified BM Ps designed to correct problems identified. Revisions to the SWPPP shall be completed within seven (7) days following inspection. Element #13: Protect Low Impact development BMPs There are no Low Impact Development BMPs in the project vicinity that could not potentially receive surface runoff from the construction site.

No. 032309-34- WSPRC Dear Rob: The Washington State Parks and Recreation Commission (WSPRC) proposes upgrading parts of an existing trail route connecting the upper (north) campground to a bridge crossing and loop trail at Dash Point State Park, Pierce County, Washington. This proposal calls for a realignment of selected trail segments to curb erosion, reduce trail grades, improve rest -rotation of vegetation cover and make improvements to creek crossings. This upgrade will require some ground disturbance. This includes vegetation removal and grubbing of new trail pathways. In addition to these trail improvements, WSPRC will also replace an existing pedestrian bridge which has been closed to public access. Please note that this is the same bridge replacement project that was first identified in 2009 (-Luttrell 2009). At that time the bridge project surveyed and examined consistent with the Governor's Executive Order 05-05. However, funding limitations prevented construction of the bridge until now. For this reason, the bridge construction project and the trail rerouting improvements have been consolidated into a single project. To insure continuity of documentation associated with merging the two projects I have included the original bridge tracking Log Number (Log. No. 032309-34- WSPRC). The project Area of Impact (AI) for this work is confined to the designated trail routes and bridge footprint identified in the attached design plans. As proposed, this project will be developed on State Park lands and is therefore defined as Capital development project (uses Capital funding). For this reason, the project is subject to the Governor's Executive Order on Cultural Resources 05-05. This Executive Order calls on state agencies to take into consideration potential impacts of their undertakings upon cultural resources. It also directs state agencies to consult with interested tribal governments about cultural resource concerns. The purpose of this letter is to introduce you to this proposed undertaking and provide you an opportunity to comment. Please find attached a letter report documenting results of a cultural resource survey for this project. No new cultural resources were identified during the survey nor will any impacts occur to existing cultural resources in the park. If you have further questions or need additional information, please contact me directly at (360) 902-8637 or at dan.meatte@parks.wa.gov .
