LD. 76519 41 CITY OF Federal Way Exhibit A FILL Findings for Project Approval Federal Way Revised Code (FWRC) Chapter 19.65 `Process III Project Approval' Panther Lake Trail, File #17-102894-00-UP The Planning Division hereby makes the following findings pursuant to content requirements of the Process III written decision as set forth in FWRC 19.65.100(4). 1. Proposal — The City's Parks Department is proposing to improve the existing social trail around Panther Lake. Improvements to the trail include a 6-foot-wide crushed rock trail mix surface and a 50-foot-long footbridge over a drainage ditch. Additional site improvements include a pervious concrete parking lot and landscaping. No buildings are proposed at this time. 2. Zoning and Comprehensive Plan Designation — The zoning for the subject property is Single Family Residential (RE35.0) and the Comprehensive Plan designation is Parks and Open Space. A public park is an allowed use in this zone pursuant to FWRC 19.200.160. 3. Site Plan Review Process — The proposed park requires review under Process III, Project Approval. 'The Director of Community Development makes a written decision on the application based on the criteria listed under FWRC 19.65.100. 4. State Environmental Policy Act (SEPA) — The environmental review required under State Environmental Policy Act (SEPA) has already been conducted (File #13-105136-SE) during review of a similar proposal that has since expired. The proposed project fits within the previous project scope. The Director determined that no new or substantially different environmental impacts are anticipated. The DNS was issued on March 26, 2014. 5. Public Notice and Comments — Pursuant to Process III and SEPA regulations, a Notice of Land Use Application was published in the Federal WaY ]!Mirror, posted at two locations at the subject property, and displayed on the designated City notice boards on July 21, 2017. No public comments have been submitted. 6. Critical Areas — The subject property contains a 5- and 10-year wellhead protection zone, geologically hazardous area (erosion hazard,) regulated lake, and wetland, which are regulated under FWRC Chapter 19.145, `Environmentally Critical Areas.' The applicant submitted a Critical Area Analysis and Rating Report, prepared by John Comis Associates, LLC, dated May 23, 2017. The on -site wetland is a Category lI wetland with 165-foot buffer. The existing path is Iocated within the wetland buffer, however, as part of this project, no significant changes will be made to the existing path location. As such, the report recommends that no buffer mitigation is needed or recommended. Instead, a split rail fence, buffer signs, and interpretive sign will educate users about the wetland and reduce the pedestrian intrusion along the waterward side of the new rail segments. Pursuant to FWRC 19.145.110(2), the operation, maintenance, or repair of existing public improvements, utilities, public or private roads, parks, trails, or drainage systems is exempt from the provisions of this chapter, if the activity does not further alter or increase impact to, or encroach 7 8. further within, the critical area or buffer and there air and no new c earing of native vegetation as a result beyond of the proposed operation, maintenance, o repair, routine pruning. 5-foot wetland buffer.

Thi0, parking for s number is appropriate for the case -by -case basis. The applicant is proposing trail project. Required Landscaping — Under FWRC 19.125.050(2), perimeter landscaping is required as follows: Type III `Visual Buffer' landscaping 10 feet along all property lines. Tile native vegetation is mature and dense on this site; the Type III landscape requirement for perimeter buffer is only required along the SW Campus Drive frontage line. here the parking lot improvements may disturbthe existing vegetation along the south propertyn require Interior parking not landscaping in the amosni3are feet..f 20 LAppl caare p er proposes parking 2901stall 1sf of int drior the 20 surface parking stalls, for a total of 400 q parking lot landscaping. Parking lot landscaping exceeds requirements. Landscape Modification The applicant has requested a modification, as all by FWRC 19.125.100, #o the requtlee landscaping along the south property line. The request is to provide a landscaping buffer, standard five feet in width, but eliminate the tree and shrub plantings in favor of the existing established groundcover. Applicant states that the reasons for the modification request are: The submitted plan shows existing native soils and hydro -seed to be used on re-created berms between the sidewalk and parking lot to retain the same rolling natural look that exists today in the parking lot footprint. The berm itself will create a modulation in look from a typical flat manicured lawn. mb As proposed, the Type III landscaping coined with the parking lot landscaping would eventually grow to screen the new parking lot. If trees and shrubs are added to the berms, the parking lot site line would be completely screened. Screening the parking lot from the road creates a security problem for patrons using the park. History has demonstrated more car break-ins, thefts, and drug deals occur if there are not adequate site -lines to a parking lot. Overall safety is a concern in a standalone parking lot. Site -lines should remain open for hide.better observe the space and patrons to feel safe with an open setting where no one can r ■ The Director hereby grants the modification request. Code language allows a modification if it represents "a superior result than that which could be achieved by strictly following the requirements - File #17-102894 /Doc ID 76509 Findings for Project Approval Page 2 Panther Lake TraiI Project of this title." The proposed modification represents a superior result in that it will: 1) create a safer environment for citizens using the parking lot; and 2) result in more native looking vegetation. 9. Clearing & Grading — Clearing and grading activities are generally consistent with applicable standards set forth in FWRC Chapter 19.120. Separate Engineering (EN) review and approval is required prior to any clearing or grading activity onsite. 10. Tree Retention/Replacement — Single-family residential zones are required to maintain a minimum of 25 tree units per acre. The total required tree units for the subject property are based on the gross land area (78.72 acres). The site is required to maintain a total of 1,968 tree units. Trees located within the wetland and wetland buffer will remain. Tree removal will occur in the parking lot area, but replacement trees are proposed within the landscaping. 11. Street Frontage Improvements — The Public Works Traffic Division has determined that the proposed trail improvements will not trigger the requirement to construct improvements along the property frontage on SW Campus Drive due to the fact that the proposal is not expected to generate any new trips during the PM peak period. 12. Vehicular Access — The proposal is to construct a driveway entering the site from SW Campus Drive. The median channelization along SW Campus Drive will need to be modified by extending the two-way left -turn lane markings further west. 13. Concurrency and Traffic Impacts —The proposal is to establish an existing social trail as a city park. Based on the trip generation estimated by the Public Works Traffic Division, the project will not generate any new trips, and as such, a concurrency analysis is not required. Furthermore, a traffic impact fee payment is also not required for this project. 14. Stormwater — The project must meet the requirements of the 2016 King County Surface Water Design Manual and City of Federal Way addendum to the manual. Pervious pavement and dispersion are proposed. 15. Parks Plan — The project is consistent with the City's Parks, Recreation, and Open Space Plan, which calls for retaining and improving our open spaces. The following is a short list of relevant goals and policies: Goal C.1: Maintain parks and open spaces so that they are inviting to users and offer facilities and activities based on the potential of each property and community need. Policy C.2: Enhance visibility into parks to increase safety and encourage use. Goal LA: Manage environmentally sensitive lands for long-term ecosystem health and biodiversity of natural systems, while making them accessible to the community. Policy LA: Maintain open spaces so that they are accessible to residents. 16. Conclusion — As conditioned, the proposed site plan application and application attachments have been detennined to be consistent with the Federal Way Comprehensive Plan (FWCP), with all applicable provisions of the FWRC, and with the public health, safety, and welfare. The streets and utilities in the area of the subject property are adequate to serve the anticipated demand from the proposal, and the proposed access to the subject property is at the optimal location and configuration Findings for Project Approval File #17-102894 / Doc ID 76509 Panther Lake Trail Project Page 3 for access.

AECOM will dig a test hole with a backhoe so footings can be designed for the future footbridge to be anchored. A separate Master Land Use Process III application will be submitted at a later date for the Panther Lake Trail project, including review of the proposed footbridge. The location of the test hole is within a regulated wetland buffer, subject to review under Federal Way Revised Code (FWRC) Chapter 19.145, Environmentally Critical Areas. Per FWRC 19.145.120(2), site reconnaissance necessary for preparing land use applications are partially exempt from this chapter and require written approval from the director. This request is hereby approved with conditions.

Landscape plan sheet L101 submitted for process III land use shows a landscape planting plan around a new parking lot per code. Preliminary comments suggest the current drawing showing hydro -seed of wildflowers would not meet the requirements of Type III landscaping between the street and the parking lot as described in Federal Way Revised Code (FWRC) 19.125.050. It is my understanding a written request for a landscape modification could be submitted for consideration. Modification Request: The Parks Department request a change from the Type III landscaping between the SW Campus Drive sidewalk and the new parking lot. Following are supporting reasons for this request: 1. The current submitted plan shows existing natives soils and hydro -seed to be used on re-created berms between the side walk and parking lot to retain the same rolling natural look that exist today in the parking lot footprint. The berm itself will create a modulation in look from a typical flat manicured lawn. 2. One problem retaining these natural looking berms for this area which range from 2' to 4' high is if we add trees and shrubs to the top of them we could completely screen the site lines to the parking lot. This could create a setting that would be unfavorable; such as criminal activity, vandalism, and illegal dumping. 3. Even if we didn't create the berms the typical Type III landscape requirements combined with the parking lot landscaping would eventually grow to screen the new parking lot. 4. Screening the parking lot from the road creates a security problem for patrons using the park. History has demonstrated more car break-ins, thefts and drug deals occur if there are not adequate site -lines to a parking lot. Overall safety is a concern in a standalone parking lot if we don't keep site lines open for police to better observe and patrons to feel safe with an open setting where no one can hide. Recommendations: 1. Instead of trees, shrubs and groundcover with type III landscape plantings, staff recommends using lower native growing type wildflowers and other related perennials that give variety, color and a natural look but doesn't grow high enough to create a screen effect between the sidewalk and parking lot. 2. The plants would continue to wrap around the parking lot and gradually introduce taller wildflower varieties with a mix of a few native trees like vine maple and shrubs on the perimeter without filling in the middle thus creating a meadow look and feel between the parking lot and the trail.

Responsible Official: Isaac Conlen, Planning Manager for Patrick Doherty, Director of Community and Economic Development Address: 33325 8t' Avenue South, Federal Way, WA 98003 Date Issued: March 26, 2014 ,Signature: Doc I.D. 65277 41k CITY OF Federal Way Date: June 15, 2017 To: Steve Ikerd, Parks Deputy Director From: Tony Doucette, P.E. Surface Water Management Engineer Subject: Panther Lake Park Trail Preliminary Technical Information Report RECEIVED JUN 15 2017 CITY OF FEDERAL WAY COMMUNITY DEVELOPMENT The purpose of this memorandum is to describe the stormwater requirements for the proposed Panther Lake Park Trail. In summary, flow control and water quality requirements will be provided by using a combination of pervious pavement with infiltration, and dispersion. Project Overview The proposed Panther Lake Park Trail improvements involve constructing a new driveway, 20-stall parking lot, and six-foot wide crushed rock trail to connect to the existing social trail. The existing social trail will be improved by grading and providing a new crushed rock surface, extending the trail to connect to the BPA trail, and providing a new pedestrian bridge. The project designer is David A Clark Architects, PLLC. Existing Conditions The project site is owned by the City of Federal Way and located at approximately 500 SW Campus Drive in Federal Way, Washington within the Hylebos Creek drainage basin. The site is situated between SW Campus drive to the south, the King County Aquatic Center to the west, the Federal Way Little League baseball complex to the east, and the BPA trail to the north/west. A map of the site and existing facilities is provided in Figure 1. In existing conditions, the proposed parking lot site is undeveloped and covered with deciduous trees. The proposed social trail expansion is currently a dirt path that includes the crest of the Panther Lake Dam and circles the perimeter of Panther Lake. Panther Lake is a natural closed depression that was expanded with the construction of the Panther Lake and Ball Field dams in 1993. The proposed parking lot is rectangular in shape with a circular vehicle turnaround and the social trail improvements are linear and meandering. The proposed parking lot site generally slopes from south to north toward Panther Lake, and the grade of the proposed trail improvements varies along the alignment. Existing storm drain features are shown in Figure 1. Additional discussion of the existing conveyance network and downstream facilities is described under Core Requirements #1 and #2. A geotechnical report was not prepared for this project, however, City staff collected two soil samples to test for cation exchange capacity and percent organic content. Infiltration testing has not been Page 1 of 9 performed and the proposed infiltration facility will use a conservative infiltration rate of 0.1 inches per hour for design of the subsurface reservoir course. Proposed Conditions The proposed parking lot is approximately 15,000 square feet, including the vehicle turnaround and driveway entrance. The full hardened surface will be constructed with pervious concrete and provide sufficient storage to infiltrate all runoff. A layout of the proposed improvements is provided in Figure 2. Proposed slopes will be less than 5% for the entire parking lot. No offsite impervious area will be routed to the pervious pavement. The proposed trail improvements extend for approximately 4,000 linear feet and will be a crushed gravel surface with vegetated side slopes that disperse into the native vegetation. A map of the proposed trail improvements is provided in Figure 3. Design Criteria The stormwater requirements for this project are from the 2016 King County Surface Water Design Manual (KCSWDM) and the City of Federal Way Addendum (CFW Addendum) to the KCSWDM dated January 8, 2017. The project site is subject to Conservation Flow Control and Enhanced Basic Water Quality requirements. Drainage Review Requirements The project proposes more than 7,000 square feet of land disturbing activity and is subject to stormwater and water quality reviews per the CFW Addendum. Soils The National Resources Conservation Service (NRCS) Soil Survey Map for King County lists the site soils surrounding the parking lot as InC (Indianola loamy sand), defined as loamy sand where the depth to restrictive features is usually more than 80 inches and the capacity of the most limiting layer to transmit water is high. InC is identified as an NRCS hydrologic soil group "A". NRCS Soil Survey Maps show the social trail alignment includes AgD (Alderwood gravelly sandy loam) and EwC (Everett-Alderwood gravelly sandy loams). AgD is definied as a gravelly sandy loam where the depth to restrictive features is between 20 and 39 inches and the capacity of the most limiting layer to transmit water is very low to moderately low. EwC is defined as a gravelly sandy loam where the depth to the restrictive feature is more than 80 inches and the capacity of the most limiting layer to transmit water is high. AgD and EwC are defined as NRCS hydrologic soil groups "C" and "A" respectively. Core Requirements Core Requirement #1— Discharge at the Natural Location Under Existing conditions, the parking lot area is undeveloped and vegetated. Runoff infiltrates, evaporates, transpires, or eventually runs off into Panther Lake. The Lake is a closed depression that retains water up to an overflow elevation where it discharges through the dam's outlet works Page 2 of 9 downstream to the West Hylebos: The proposed improvements will continue to discharge to Panther Lake. Core Requirement #2 — Offsite Analysis The study limits of this Level 1 offsite analysis extend % mile downstream from the project discharge point. The Hylebos Basin Plan, City mapping, NRCS soil surveys and citizen action request databases were reviewed as part of the analysis. The Panther Lake Dam project was completed in 1993 and increased the capacity of the existing Panther Lake natural depression. Improvements included raising the berm, improving the spillway and constructing the ballfield dam as a structure in series with the Panther Lake Dam. King County maps show that the east and west sides of the Panther Lake parcel are mapped as erosion hazard areas, that the site's susceptibility to groundwater contamination is medium to high, and that the site is within wellhead protection areas with five to ten years of travel time (capture zones 2 and 3). The site is outside of the Wellhead capture zone 1. Runoff draining to the lake that rises to the dam's primary spillway enters the piped outlet works and is conveyed in a 27" corrugated metal pipe (CMP) that drains under the existing ball fields, under the ballfield dam and into the existing City maintained storm drain system. The storm drain system drains south through the Win -Co Parking lot, crosses SW Campus Drive and enters an open channel south of the intersection of SW Campus Drive/S348th Street and 15t Ave S. When runoff draining to the lake rises up to the gabion overflow spillway, water is impounded behind the ballfield dam and drains through the ballfield dam outlet works into the same storm system draining the Panther Lake Dam primary spillway. The City's citizen reporting database and work order tracking system shows no flooding or nuisance water issues downstream, along the length of the existing storm drain, and at the storm drain outlet. No known issues need to be addressed with this project and no known issues will be made worse with the completion of this project. Core Requirement #3 — Flow Control The project is located in a Conservation Flow Control area, requiring improvements to meet historic forested condition flow durations. However, all target areas for the project will either infiltrate with pervious pavements (the entrance and parking lot) or disperse (along the trail improvements). Analysis of the proposed parking lot pervious pavement is provided in Attachment 1. No new flow control facilities will be provided. Core Requirement #4 — Conveyance System No new conveyance system will be provided because the hard surfaces will be pervious with reservoir courses and the social trail improvements will disperse. An underdrain is not proposed for the pervious paving parking lot. Core Requirement #5 — Erosion and Sediment Control Erosion control plans will be prepared for this project based on the thirteen measures outlined in section 1.2.5 of the KCSWDM. Page 3 of 9 1. Clearing Limits will be shown on the plan to minimize the construction footprint and existing vegetation will be preserved to the maximum extent practical. 2. Cover measures will be employed for all soil and material stockpiles and disturbed areas not receiving temporary or permanent stabilization within one week during the dry season or within two days during the wet season. 3. A silt fence will be used along the downhill edge of the trail alignment and at the parking lot and entrances in combination with straw wattles. 4. Traffic area stabilization will be provided by stabilized construction entrances and any material tracked onto adjacent paved streets will be swept and removed. 5. Temporary sediment retention will be provided by the perimeter silt fence and straw wattle BMPs. Storm drain inlet inserts will also be installed in adjacent catch basins within SW Campus Drive. 6. No surface water will need to be collected during construction of the project. 7. Construction dewatering will not be needed. 8. Dust control will be provided by water application as necessary at the minimum rate necessary to prevent dust pollution. 9. Flow control is not required or provided by this project. 10. -13. Pollutants will be controlled, flow control BMPs will be protected and maintained, and the erosion and sediment control plan will be actively managed throughout the project. In addition, the proposed pervious surfaces will be protected from sediment contamination following installation. Core Requirement #6 — Maintenance and Operations Manual Maintenance and operations of the proposed facility will be conducted consistent with Appendix A of the KCSWDM. Core Requirement #7 — Financial Guarantees and Liability The project is a City Parks and Recreation project to be constructed on a City owned parcel. Financial guarantees will not be required. Core Requirement #8 — Water Quality A water quality review is required per the CFW Addendum because the project proposes more than 7,000 square feet of land disturbing activity. The project is in an enhanced basic water quality treatment area and target surfaces include new pollution generating impervious surface (PGIS), pollution generating pervious surface (PGPS), existing impervious surfaces added since January 8, 2001, and replaced PGIS and PGPS. The proposed parking lot is approximately 15,000 square feet, exceeding the 5,000 square foot threshold for PGIS. Since water quality is required, the CFW Addendum requires that the entire site must be brought up to water quality standards. Page 4 of 9 Water quality for the site will be accomplished by using pervious pavement and infiltration at the proposed parking lot and dispersion along the social trail improvements. The proposed infiltration location is located in a wellhead protection area 3 (10-year travel time) and outside of erosion hazard areas identified in previous sections. City staff collected soil samples to verify the cation exchange capacity (CEC) and percent organic content of the existing soil and found it suitable for water quality treatment. Two samples were taken each for CEC and percent organic content, one each at the east and west ends of the proposed parking lot. Values for CEC were 190 and 200 for east and west respectively, and percent organic content values were 7.1% and 14%. Both sample locations exceed the required CEC of 5 or greater and percent organic content of 1% or, greater. A full report of laboratory testing results is provided in Attachment 2. Special Requirements Special Requirement 1 — Other Adopted Area -Specific Requirements There are no adopted area -specific requirements that apply to this project beyond what is required by the KCSWDM and the CFW Addendum. Special Requirement 2 — Flood Hazard Area Delineation Special requirement 2 does not apply to this project because no flood hazard areas exist on or adjacent to the project site. Special Requirement 3 — Flood Protection Facilities Special requirement 3 does not apply because the project will not rely on or modify an existing flood protection facility. Special Requirement 4 — Source Controls Source controls will not be required for this project because there is no commercial building or commercial site development permit. Special Requirement 5 — Oil Control Special requirement 5 does not apply because the proposed park improvements do not meet any of the KCSWDM definitions for a high use site.

Summary of Wetland -Rating and Buffer Requirements The wetland rating follows the City of Federal Way Municipal Code requirements for Critical Areas in accordance with FWRC 19.145.420 (Wetland rating and buffers). This specifies that wetlands shall be rated according to the Washington Department of Ecology wetland rating system, as set forth in the Washington State Wetland Rating System for Western Washington — 2014 Update (WDOE Publication No. 14-06-029, or as revised and approved by WDOE). The details for the methodology used for this wetland analysis are described in this report in Appendix 1. This appendix includes details about how the wetland was determined or identified; key definitions used; wetland delineation methods (by reference to the 1993 report by Brown & Caldwell Consultants); wetland classification (by vegetation classes); and the City of Federal Way regulations and buffer standards used to prescribe required buffer widths (165 feet). The onsite wetland unit is designated by this study as the "Panther Lake Wetland". This study produced results that indicate the wetland is rated Categoal°_I I for regulatory purposes based on the "Washington State Wetlands Rating System for Western Washington-2014 Update" (See WDOE Wetland Rating Form completed by JCA in Appendix 2 for details). The total score for functions is 22 points, water quality score is 8 points, the hydrologic score is 7 points, and habitat score is 7 points. This rating is made by JCA based on field observations of wetland conditions for a "depressional" wetland that exists at this time. This rating includes all of the onsite portions of the wetland unit shown by map data provided with this report (see Figures 1 thru 9). In accordance with FWRC 19.145.420 (Wetland rating and buffers), the standard buffer width for a Category II wetland with a Habitat score of 7 points is required to be 165 feet. (See Appendix 1, E for details and applicable code references) This wetland is large, hydrologically connected to the West Fork of Hylebos Creek. The HGM classification for Panther Lake Wetland is a "depressional' wetland in accordance with the Washington State Department of Ecology (WDOE) using the Hydrogeomorphic Method (HGM) classification system. This is based on the "landscape" position or location of the wetland or portion of wetland within the landscape with surrounding areas within certain radii (see Figures 1 thru 3 for details). The wetland vegetation classification follows a hierarchical multi -level approach developed by the US Fish and Wildlife Service (USFWS) for a scientific classification system. The USFWS classification system is published in the report titled Classification of Wetlands and Deep Water Habitats of the United States, FWS/OBS-79/31, by Cowardin, et al. (December 1979). The vegetation classes within the Panther Lake Wetland consist of all 4 classes (aquatic bed, emergent, scrub -shrub, and forested with at least 3 out of 5 strata); and the plant community is diverse and prolific (more than 19 species are present). No significant changes will be made to existing path locations, except as noted on the "Panther Lake Wetland Overview with Loop Trial Improvements, DACA sht G106, 050117" (Figure 9). This report provides an analysis of how much of the proposed project is situated within the wetland buffer. Figure 9 shows the overall project area including the 165-foot wide standard buffer boundary around the Panther Lake Wetland. The designated wetland buffer also includes any effected stream habitat areas that may be impacted by the proposed loot trail improvements. In summary, this report recommends that "no buffer mitigation is needed or recommended if split rail fences and buffer signs are completed at the locations indicated on Figure 9." [See Appendix 4 for recommended fence and sign details] Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 4 of 37 2. Classification -of Panther Lake for Wetland Rating On first impression, Panther Lake appears to qualify as a "Lacustrine" or Lake Fringe" wetland —this is based on its name and its general appearance on the landscape (see Aerial Photo Maps provided with this report). However, this is not the finding of this study based on a hydro -geomorphic (HGM) classification system adopted by the WDOE and promulgated in their manual for wetland ratings.2 There are two (2) key criteria for a wetland to be classified as a "Lake Fringe (Lacustrine Fringe)" wetland. The first one is that the vegetated part of the wetland along the shoreline that is to be rated is "on the shores of a body of permanent open water without any plants on the surface at any time of the year that is at least 20 acres (8 ha) in size"; and the second one is "at least 30% of the open water area is deeper than 6.6 ft (2 m)„ Panther Lake is a large impounded area that historically existed in this landscape area for many years. It was originally studied in some detail in 1974 for a flood study as a natural impoundment for surface water runoff control from southern King that flows into northern Pierce County.' It was delineated in detail in 1992 by Brown & Caldwell Consultants.4 This wetland has a total area that is less than 5 acres in size and a maximum depth that is approximately 4 feet deep. Furthermore, its vegetated shoreline extends out into the shallower part of the wetland for more than 1/3 of the delineated area, and the emergent and aquatic bed portions of the wetland extend across the entire surface of the impoundment for at least part of the growing season. For these reasons, this wetland does not meet the criteria for a "Lake Fringe" class. However, this wetland does meet the criteria for a "Depressional" class as indicated by the rating provided with this report in Appendix 1. It should be noted that the wetland unit still meets the criteria for rating as a "Depressional" class based on conditions set forth in the WDOE rating manual when multiple HGM classes may be present. When Panther Lake wetland is evaluated to have a Slope wetland on the southern and northern sides where influent streams grade into a depression, or if a Lake Fringe extends along parts of the interior area and grades out to a Depressional wetland along the sides, then by identifying which of the hydrologic regimes (described in questions 1-7 on the rating from) apply to these different areas of the wetland unit, we can identify the dominant HGM class that is present within the wetland unit. The wetland class that represents more than 90% of the total area of the wetland unit is a "Depressional" class (see the second column under item #8 at the bottom of page 4 on the rating form for more details). JCA completed the current field investigation at the project site on 02/07/17. JCA also attended a meeting on 01/17/17 with the project applicant (Federal Way Parks & Recreation), the project's architect (David A. Clark), and the Planning Department staff to discuss our findings and recommendations prior to preparation of the JCA wetland report. At that meeting we concluded that a new wetland rating would be prepared by JCA for the Panther Lake Wetland and an analysis of the potential impacts to the wetland buffer by a modified loop trail plan would be included with recommendations for mitigation that may include split rail fencing and buffer boundary signs.

Previous Wetland Studies in the Project Area In 1993, Brown & Caldwell Consultants (B&C) published a final report titled "Panther Lake Surface Water Study —Final Report", September 1993. The B&C report described their findings in detail and included detail data and information about the Panther Lake and it's contributing tributary watersheds. It also included a detailed wetland delineation around the perimeter of the entire wetland as required by the City to be in accordance with the then current 1989 manual methods. "Wetlands" within the project site were delineated by Brown & Caldwell using the Federal Manual for Jdent yying and Delineation Jurirdictl nal i,Yetlande federal Jnteta ire Committee or l,Yetlandr Delineation 1989 .5 Specific details from the B&C study were used by JCA for updating the wetland rating for Panther Lake. These data include the size of the wetland; the overall size of the contributing watershed around the wetland that drains to a point of concentration at the outlet from the wetland; and the height of ponding in the wetland above the bottom of the outlet. The height of ponding is used to determine the depth of water storage during wet periods in the wetland. This may be determined from bathymetry data and the measure from the surface of permanent water level to the elevation of the ordinary high water mark (OHWM) around the edge of the wetland. • The overall wetland size delineated by B&C in 1992: wetland area was 16.5 acres as described in the narrative on page 4-11 (page 57 in the digital PDF copy); • The watershed size that is directly tributary to Panther Lake: drainage areas were described in the narrative on page 3-2 as approximately 1,650 acres. However, that was reevaluated in more detail and total revised tributary area was indicated as 1,310 acres in the table on page 5-6 (page 78 in the digital PDF copy). (see Figure 5, Map of Contributing Basin, in the JCA report) • The depth of storage in the lake during wet periods: calculated by JCA to be 2.78 feet based on the invert elevation of the 27" corrugated metal pipe outlet at 247.22, and the normal high water level around the wetland at contour 250 or less as shown on the bathymetry map (see Figure 6, Map of Wetland Delineation & Bathymetry, in the JCA report). Data for depths of ponding in the lake are in the source report as stage -storage -discharge relationships in the narrative on page 5-4 (page 76 in the digital PDF copy). Other data that was provided by the City and obtained from earlier engineering designs included details of the outlet structure and spillway. The invert elevation (IE) of the 27" CMP outlet pipe is shown as 247.22, and the spillway elevation is shown as 257.4. The survey of the overflow crest that was done this year, 2017, confirms that the spillway crest is between elevation 257.47 and 256.65. JCA has also checked an older study that was published in 1974 that this investigator had personally worked on titled "Hylebos Basin Drainage Plan" by Consoer, Townsend & Associates for Pierce County Public Works Department and the "Hylebos Flood Control District". JCA found that the subwatershed area that was mapped in 1974 as tributary to Panther Lake was approximately 1,300 acres. However, it appears that the watershed has changed since that time due to development and changes to drainage patterns water flow paths in the surrounding tributary area. In 2015, The Watershed Company (TWC) prepared a number of site plan sheets that indicated mitigation measures needed around the entire wetland if major changes were to be made to the trail system. Huitt- Zollars (HZ) provided engineering designs for major trail improvements that were done concurrently with the landscape mitigation design plans. 5 Wetlands delineated at this time use the 1997[3'ashinQran Siale iYetlands ldenrrfieorion and !]elineatlan Manual, prepared by the Washington State Department of Ecology (WDOE Publication #96-94) and modified at this time to be consistent with the 2010 US Army Corps of Engineers Regional Sir lenient to the Carps o L "neers 6Yetland Qe1ine060?r Hanual: Western MOnnralnS i'al/eus and Coast Region (USAGE 2010) lain.lhau��,usacc.amri.milli'�r�alal7Jds slrjv_i!_w� u�tnrvlrep supp st nit �nalsuoo.t>df Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 6 of 37 4. Wetland Rating Discussed The "rating" (or category) of a wetland is based on the 4-tiered system as required by City of Federal Way Municipal Code (FWRC). The use of this rating system basically assists in determining the appropriate amount of protection needed for a particular wetland and the buffer standards and setback requirements applicable to that wetland area. Excerpts from the City Code are included with this report in the `Methodology' Appendix I.E. This includes excerpts from the current online code which has specific details for wetland rating that must be done in accordance with the 2014 updated WDOE manual. Panther Lake Wetland is rated Category III with a total score for functions at 22 VoWU; water quality score at 8 points; hydrologic functions score at 7 points; and habitat functions score at 77points. This rating is based on a "depressional" HGM classification system and field observations by JCA of conditions that exist at the time of this study. (See WDOE rating form completed by JCA in Appendix 2 for details). The wetland rating form completed by JCA includes data and information obtained from available sources. The maps and figures required to answer the questions correctly for the rating form for a "depressional wetland" are indicated on page 2 of the completed form by JCA in Appendix 2. Copies of these data are included with this report. Please refer to the aerial photo maps, topography, and drainage maps provided with this report for specific sources and reference information used for this rating. Various radii are used in this analysis for the updated wetland rating that include the i h'm radius as the maximum area required for rating a wetland. Other radii used include 150 feet, 250 feet and 330 feet. These radii are used for various parts of the analysis as described in the manual (see list of figures provided on page 2 in the completed form in Appendix 1 for details). The wetland rating includes the 303(d) List for this area used by JCA for this analysis. See map Figures 1 thru 3 for Aerial Photo Maps that are marked by JCA with various radii, habitat, land use, and vegetation classifications overlays. See Figure 7 for waters in the project area, and Figure 8 for the lower Hylebos watershed area. 5. Potential Impacts from Proposed Project Development Please refer to the "Panther Lake Wetland Overview with Loop Trial Improvements, DACA slit G106, 050117" (Figure 9) for the general layout of the loop trail improvements in 3 segments around the project site. The Q4al of this plan is to make the loop trail accessible, safe, and provide as much view of natural habitat and experiences as possible to the trail users. Potential impacts to the Panther Lake Wetland are evaluated and measures are recommended that avoid or minimize impacts by preserving adequately vegetated buffers between the delineated wetland edge and the new loop trail improvements. Where new trail improvements are located within the buffer area such as along the west and south sides of the wetland, the plan provides mitigation by the addition of split rail fences and buffer signs to minimize potential impacts due to inadvertent pedestrian intrusion. These are only recommended where trail improvements extend inside the standard width buffer. [See Figure 6 for recommended locations and Appendix 4 for recommended fence and sign details] Potential impacts to the southern end of the wetland buffer include a new loop trail with footbridge over the southern stream corridor and a 21 stall parking lot with street access. These improvements may cause significant impacts to the Panther Lake Wetland if abatement measures and/or control measures are not implemented. The main impacts would occur during construction if measures for limiting intrusion and sediments are not implemented such as construction fencing and silt fencing along downhill sides of the clearing and grading areas. After construction is completed, the potential impacts may occur from the normal and expected pedestrian use of the new loop trail around the southern end of the wetland. Most of the existing loop trail around the wetland will not be disturbed or significantly changed by the proposed plan for improvements along the northern, western, and eastern parts of the trail. The existing Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 7 of 37 social loop trail crossing through the northern end of the buffer area and the existing wood bridge crossing over the stream corridor that flows into the northern end of the wetland will not be significantly changed. This northern area will have minor grading and filling along the existing trail to remove the rollers associated with limited pedestrian access along the present trail. No changes will be made to the existing wooded bridge over the stream. Main Objectives of the new Loop Trail Plan compared to the 2015 larger Trail Plan Improvements: 1. Use as much of the existing dam structure as possible around the eastern side of the wetland and not change the trail location, but top -dress the surface with a special crushed rock we call `trail mix' from WA Rock quarry. This same trail mix rock would be used throughout the loop trail system. 2. Use as much of the social trail that currently exist around the lake and not do a major trail revision as was shown in the original plans by HZ and TWC. 3. Use 4 or 5 adjusted alignments along the existing social trail to make the loop trail pedestrian assessable. 4. The path will be narrower than the original proposed width of 10' to 6' to reduce or eliminate vegetation disturbances or need for additional mitigation. Much of the existing social trail and Eagle Scout projects have a 4-5' wide trail today. 5. Continue the short trail section sharing the BPA trail in the loop to get around the difficult wet terrain. 6. Add a new proposed foot bridge to keep the loop trail from going out to the west Campus sidewalk. This would be accessed from the west side of the wetland from the BPA trail section next to the Aquatic Center parking lot, and loop back across the southern side of the wetland just north of the new parking lot to connect back with the existing dam section of the trail. 7. Add anew parking lot outside the buffer zone at the southern side of the lake with 2-way ingress and egress for access from SW Campus Drive. Main elements of the new loop trail plan include the following: ■ Add a total of 4,569 lineal feet of 6-foot wide pervious trail (crushed rock trail mix) around the lake at 4 designated improvement areas in the locations shown on Figure 9, • Add a new foot bridge that is open span and at least 10 feet over the southern stream corridor to keep the trail off the street and not impact the tributary stream at the southern end of the lake, ■ Add a 21 car parking lot in the southern part of the project area, ■ Routing of pathways will remain essentially unchanged, • No new restroom building will be added, ■ No new playground will be added. The portions of the loop trail that will be improved are shown on the "Panther Lake Wetland Overview with Loop Trial Improvements, DACA slit G106, 050117" Figure 9. Potential impacts to wetland functions include the following: A. Increase or decrease in surface runoff from proaect develo went The relative increase in the rate of discharge into the adjacent wetland areas where new pervious pavements are installed for loop trail surfacing should not be significant due to minor changes in surface Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 8 of 37 drainage patterns that may occur. The proposed pervious pavements for the new trail and parking area that will be constructed in the southern part of the project site will infiltrate storm water runoff into the natural subsoil and should not significantly impede or change the runoff rate or flow paths in this area. Please refer to detailed engineered plans by David A Clark Architects that are provided with this project proposal and submitted under separate cover to the Planning Department. The sub -watershed areas that contribute surface runoff to Panther Lake Wetland will not be changed by this development. The established drainage patterns for surface water runoff from surrounding areas that flow into the wetland will not be changed or altered by this plan. Furthermore, any groundwater sources for hydrology which support the wetland ecology should not change after this development is constructed. B. Increase of sediments and nutrients from pro ect development Potential impacts from sediments may be significant during site preparation and new construction in the southern part of the project site due to disturbances from clearing and grading activities such as along the new loop trail, parking area, and footbridge crossing the stream corridor. However, siltation fence(s) are proposed along waterward sides of the new trail and bridge construction area. Silt fences should be constructed along these areas prior to the start of construction to reduce potential impacts. Silt fences should remain in place until the construction areas become stabilized. The natural vegetation in the buffer that is preserved by this plan around the wetland can assimilate minor increases in nutrients coming from the adjacent, tributary trail and parking areas. The native vegetation that will be preserved in undisturbed areas including the wide area between of the new construction in the southern part of the site and the wetland, can assimilate minor increases in nutrients coming from runoff from the trail and new parking lot that may not drain directly into the pervious pavement control system (i.e. that is from some small areas that inadvertently run off from the pavement and flow toward the wetland). That runoff will remain tributary to the wetland and will preserve the existing hydrology source for the wetland. Any nutrients from this area should not be significant or adversely affect the wetland. C. Disturbance of wildlife habitat by proiect develovinent There are no endangered, threatened or sensitive ANIMAL species known to inhabit the project site. This is based on our observations at the site and comparison with current publications by the Washington Department of Wildlife titled "Washington Priorin, Habitats and Species", "Status Report on Cndan ered and Threatened Species", and "Non ante Data Systems Special Animal Species List". These lists also include species of "special concern" as non -game animals. The wildlife habitat value for Panther Lake Wetland is judged to be "high" (see Appendix 2 for rating summary based on functions). However, the rating for "landscape potential" is judged to be "low". This is due to its proximity to existing roadways and developments adjacent to the all sides of the wetland. The accessible habitats that include undisturbed habitat and moderate and low intensity land uses are relatively low even for this large wetland due to the surrounding land uses and dissected areas due to major and minor roadways crossing through the surrounding areas. (see map figures provided with this report and listed on page 2 of the rating form in Appendix 2). The habitat functions due to structure in the plant community around and within the wetland are relatively high due to diversity and interspersion among wetland classes. However, there are no major habitat features observed at this time such as beaver use, heron rookery, or other major habitat features within the regulated wetland area. Wildlife habitat is available in this wetland area for priority habitat types due to the structural diversity (tall trees and forest cover) around most of the wetland edge, and the perennial availability of surface water in the central part of the wetland. Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 9 of 37 The impacts to habitat in the central part of the wetland from this development are judged to be "low" or "no effect" from construction of new loop trails or parking area. The construction of the new footbridge across the ravine and stream corridor may have impacts if the tail and footbridge crossing do not provided adequate care and protections in accordance with the engineered construction plans. The size of the regulated wetland will not be decreased and "no net loss" in wetland functions or value appears to result with the implementation of this plan. The initial disturbances to habitat due to construction activity will cease after it is completed. A Human use recreation education or other uses Humans will continue to use the existing and established loop trail around Panther Lake Wetland for recreational and educational activities that are normally associated with this park use. However, humans will not use or enter into the delineated area of Panther Lake Wetland. No formal uses within the boundary of the delineated wetland are planned at this time or in the future for direct use of the wetland by humans. No regulated activity including building, clearing, filling or grading is planned or proposed within the delineated wetland, except as may be approved by the City for such reasons as flood control, maintenance of existing outlet structures, or possibly hazard tree removal if it becomes necessary around along walking trails or parking areas. All regulated activities should occur only in areas outside the delineated wetland boundary wherever possible. 8. Standard Buffers and Mitigation Measures Recommended The updated wetland rating for the Panther Lake Wetland is Category II, with a Habitat score of 7 points. The standard buffer width for this category of wetland and habitat score is required to be 165 feet (not 200 feet as originally shown on the maps and site plans for the project prepared in 2015 by The Watershed Company. The FWRC 19.145.420(2) requires that wetland buffers be measured perpendicular from the wetland boundary as delineated and marked in the field. Buffer widths are established as follows: Minimum Buffer Buffer Width Buffer Width Buffer Width Width (wetland scores (wetland scores 5 (wetland scores 6 (wetland scores b - Wetland Category 3 —4 habitat points) habitat points) — 7 habitat points) 9 habitat points) Category I: 190 feet 190 feet 190 feet 225 feet Bogs and wetlands of high conservation value Category I: 75 feet 105 feet 165 feet 225 feet Forested and based on function score Category II 75 feet 105 feet 165 feet 225 feet Category III 60 feet 105 feet 165 feet 225 feet Category IV 40 feet 40 feet 40 feet 40 feet Buffers are required to be preserved around a regulated wetland to limit or mitigate impacts that may arise from new buildings or changes to land use in the development area. These impacts can include such things as glare, noise or intrusion into the wetland that may arise from new sources near the wetland. Upland buffers preserve valuable upland habitat that is used by wildlife within and adjacent to the wetland. Panther Lake Wetland is required to have a standard buffer width of 165 feet. This buffer width includes adjustments for low levels of potential habitat impacts due to the ongoing use of the existing loop trail around the lake. It does include temporary impacts due to construction for trail improvements. However, Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 10 of 37 these impacts will cease after the construction is completed and the work areas will be cleaned up and restored. No other protection is applicable due to minor improvements to segments of the loop trail as indicated by the excerpts from the applicable City Code in Appendix I.E. No buffer mitigation is needed or recommended if the split rail fences and buffer signs are completed as indicated on the "Panther Lake Wetland Overview with Loop Trial Improvements, DACA sht G106, 050117". All of the new parking lot is outside the southern buffer area and only the new trail and new foot bridge extend into the buffer along the southern side of the wetland. The corner of the new access driveway extends into the buffer in this area, however, it will have pervious pavement and will not drain directly to the wetland. This means that the modified plan will have "minimum potential impacts to the wetland and buffer area", and these minimized impacts will be mitigated by the addition of the required silt fence, and the installation of a split rail fence with signs posted for the reduction of pedestrian intrusion along the waterward side of the new trail segments. [See Figure 9 for recommended split rail fence locations and Appendix 4 for recommended fence and sign details].

METHODS USED FOR WETLAND DETERMINATION OR IDENTIFICATION The identification of "wetlands" by JCA for this analysis was consistent with applicable manual methods and in accordance with the requirements in the Federal Way Municipal Code (FWRC). JCA used the most recent editions of the federal and state wetland manuals and applicable regional supplements as approved and adopted by the Washington State Department of Ecology (WDOE). This appendix describes the methods used including key definitions, criteria, abbreviations, regulation standards and applicable portions of code requirements used in this analysis. "Wetlands" within the project site were delineated by Brown & Caldwell Consultants in 1992 using the Federal Manual for Identi(yin-g and Delineation .lurisdictional ffetlands (Fedeml Interagency Committee for 111ellands Delineation. 19�. This manual replaced the pervious methodology used in the Cor s o En ineers fYetland Delineation Manual (USACE 1987).6 As described in the B&C report,' the City of Federal Way required B&C to evaluate the project wetlands according to the 1989 manual (by personal communication from Greg Fuens, Senior Planner, February 20, 1992). B. KEY DEFINITIONS USED For this study, "wetlands" are defined using the adopted State of Washington's Growth Management Act definition in RCW 36.70A.030(21): "Wetland" or "wetlands" means areas that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soils conditions. Wetlands generally include swamps, marshes, bogs, and similar areas." (Corps of Engineers Regulation 33 CFR 328.3, 1988) (Federal Resister 1982), the Environmental Protection Agency (Federal }register 1985), the Shoreline Management Act (SMA), and the Growth Management Act (GMA) In addition, the SMA and GMA definitions added: "Wetlands do not include those artificial wetlands intentionally created from non -wetland sites, including but not limited to, irrigation and drainage ditches, grass -lined swales, canals, detention facilities, wastewater treatment facilities, farm ponds, and landscape amenities, or those wetlands created after July 1, 1990, that were unintentionally created as a result of the construction of a road, street, or highway. Wetlands may include those artificial wetlands intentionally created from non -wetland areas to mitigate the conversion of wetlands." Other key definitions may also apply that are in the adopted City of Federal Way Municl l Code (FWRC) for Wetlands, Chapter 19.145 including code sections specifically pertaining to wetland rating and buffer widths (FWRC 19.145.420, see Section E in this report for more details about applicable City wetland regulations that are applicable to this analysis). C. WETLAND DELINEATION 6 Wetlands delineated at this time use the 1997 li'ashia2ran Srare Hrertands tdentirlwrion and LWimarion Manual, prepared by the Washington State Department of Ecology (WDOE Publication #96-94) as modified at this time to be consistent with the 2010 US Army Corps of Engineers Re 'anal SunWement to the Corps of Engineers Wetland Delineation h?mnsat: ffesrern Mounraws, VolleuT and Coast Region (USACE 2010). http;lhntiw usace army mill Ponalsl2ldecslcivilwork /rc ulatory/mg1sunnlwest mlJinalsuou.ndF ' Ref. "Panther Lake Surface Water Study Final Report", Sept 1993, by Brown & Caldwell Consultants for the City of Federal Way Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 13 of 37 When "normal circumstances" exist on the site, vegetation is used where plants are established and relatively undisturbed. These circumstances are considered "typical" situations as compared to "atypical salutations" where one or more of the 3 parameters (vegetation, soil, and/or hydrology) have been sufficiently altered or disturbed. The legal definition of wetlands p contains the phrase "under normal circumstances," which was included because there are instances in which the vegetation in wetlands may have been inadvertently or purposely removed or altered as a result of recent natural events or human activities. "Recent" is defined to mean that period of time since legal jurisdiction of an applicable law began. For this study, the vegetation, soils and hydrology analysis has already been done by Brown & Caldwell Consultants, and published in their report titled "Panther Lake Surface Water Study —Final Report", September 1993, for the City of Federal Way. JCA has reviewed this report and finds that it still valid as it applies to this wetland delineation and its associated landscape features. D. WETLAND CLASSIFICATION For the purpose of this study, different types of wetlands are separated from one another on the basis of wetland class and wetland category. Wetland class is a scientific system based upon dominant plant communities, substrate conditions, hydrologic regime, and location in the watershed. Wetland classification is a categorization system used to regulate land uses adjacent to wetlands. Wetland Class: a science -based classification system is used based on a U.S. Fish and Wildlife Service publication titled C'lassifrcatian of Wetlands and DeeWu,ater Habitats of the United States that was edited by Lewis M. Cowardin, et at, and published in December 1979. Cowardin divides wetlands into five systems (Marine, Estuarine, Riverine, Lacustrine, and Palustrine), eight subsystems (Subtidal, Intertidal, Tidal, Lower Perennial, Upper Perennial, Intermittent, Limnetic, and Littoral), 10 classes, and numerous modifiers. A combination of the system name, subsystem, name, class, and a modifier forms a code that identifies the wetland class. WDOE expanded the tern wetland class by incorporating use of the Hydrogeomorphic Method (HGM) classification into the "Washington State Wetland Rating System for Western Washington--2014 Update" (WDOE Publication No. 04-06-029). The HGM is based on the "landscape" location of a wetland or portion of a wetland. The HGM classes are Depressional, Riverine, Lake -fringe, Slope, Flats, and Freshwater Tidal. Wetlands identified by this study are classified using a hierarchical multi -level approach developed by the US Fish and Wildlife Service for their scientific classification system. The classification system is published in the report titled Classification of Wetlands and Deep Water Habitats ofthe united States, FWS/OBS-79/31, by Cowardin, et at. (December 1979). The system of classification divisions is based on habitats that share the influence of similar hydrology, geomorphology, chemical, or biological factors. The wetland systems involved in the project site are generally limited to "Palustrine" systems. Palustrine wetlands (these are the only wetlands identified within this study area) are divided into 9 classes with 24 different subclasses. These are determined by either the substrate material or the `dominance vegetation' associated with a respective non -tidal area. The classes of non -tidal palustrine systems are as follows: CLASS [NON -TIDAL) (RB) Rock Bottom (UB) Unconsolidated Bottom 8 WDOE 1997 Manual, paragraph 25a, page 9, Definition (from Federal Register, SMA and GMA) Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 14 of 37 (AB) Aquatic Bed (US) Unconsolidated Shore (ML) Moss -Lichen (EM) Emergent (SS) Scrub -Shrub (FO) Forested (OW) Open Water (unknown bottom) The subclasses are not identified in this study area but if assigned they would be based on the substrate material or `dominance vegetation' associated with the non -tidal area. `Dominance types' may also be characterized within freshwater Palustrine Systems based on different invertebrate fauna that typically inhabit these areas. Water regimes are assigned for each class based on the hydroperiod or duration of flooding (inundation) or saturation associated with the non -tidal area. These are defined for non -tidal (freshwater) areas as follows: WATER REGIME [NON -TIDAL] (A) T m rani I flooded: flooded (inundation by surface water) for brief periods during growing season but the water table is otherwise well below the soil surface (B) Saturated: substrate is saturated for an extended period during growing season but surface water is seldom present (C) Seasonal i y flooded: flooded for extended periods during the growing season, but usually no surface water by the end of the growing season (D) Sea.,soriallyflooded/well drained (E) Seasonally flooded/saturated: flooded for periods, but usually saturated by groundwater at or near the surface thru most of the growing season (F) Semi ermanentl flooded: flooded throughout growing season in most years, when surface water is absent, water table is at or near the surface (G) Intermittendy exposed: flooded throughout year except in years of extreme drought (H) FeIrManently flooded: flooded (water covers land surface) throughout the year in all years (J) Intermittentl flooded: surface is usually exposed with surface water present for variable periods with no seasonal pattern (K) Artificially flooded (W) Intermittently flooded/temnorary_ (Y) Satu a /semi- ermane easnal (Z) Intermittently exposed/permanent (U) Unknown SPECIAL MODIFIERS (b) beaver (d) partially drained/ditched (f) farmed (h) diked/impounded (r) artificial substrate (s) spoil (x) excavated Other modifiers for water chemistry and soil may also be employed to more adequately describe the wetland and deepwater habitats. These may be applied at the class or lower level in the hierarchy. The farmed modifier may also be applied to the ecological system. The class of a particular wetland describes its general appearance in terms of either the dominant vegetation or the substrate. When over 30% cover by vegetation is present, a vegetation class is used (e.g., "emergent", "scrub -shrub" and/or 'forested'). When less than 30% of the substrate is covered by vegetation, then a substrate class is used (e.g., "unconsolidated bottom", "aquatic bed', or "moss -lichen"). Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 15 of 37 Typical demarcations of these classes of palustrine wetland systems are shown in the Cowardin report. [Also reference is made to the current (1988) National Wetlands Inventory (NWI) map and legend.] Wetlands that have a single vegetation species that dominate 90% of the total wetland area are called a "mono -type". This may occur where more than the one species is present but the total area of their coverage is less than 10%. If another vegetation class or species dominates more than 10% of the wetland, then it has higher habitat diversity. This can be based on the number of plant species found in a class, the number and quality of the structural layers and the interspersion of classes which creates increased "edge effect" and habitat diversity. This may also result in a higher wetland "rating". E. CITY OF FEDERAL WAY WETLAND REGULATIONS AND BUFFER STANDARDS The standards adopted in the City of Federal Way Municipal Code (FWRC) for ENVIRONMENTALLY CRITICAL AREAS are covered in Chapter 19.145 of the City's code. These standards include updates adopted by Ord. No. 15-797, § 22, 6-16-15.

Acreage estimates, classifications, and ratings shall be based on entire wetland complexes, not only the portion present on the subject property: (i) Wetland rating and score for each function; (ii) Required buffers; (iii) Hydrogeomorphic classification; (iv) Wetland acreage; (v) Cowardin classification of vegetation communities; (vi) Habitat elements; (vii) Soil conditions based on site assessment and/or soil survey information; and (viii) To the extent possible, hydrologic information such as location and condition of inlet/ outlets, estimated water depths within the wetland, and estimated hydroperiod patterns based on visual cues (e.g., algal mats, drift lines, and flood debris). (g) An evaluation of the functions of the wetland and adjacent buffer. Include reference for the method used and data sheets. (Ord. No. 15-797, § 22, 6-16-15.) 19.145.420 Wetland rating and buffers. (1) Rating. Wetlands shall be rated according to the Washington Department of Ecology wetland rating system, as set forth in the Washington State Wetland Rating System for Western Washington — 2014 Update (Ecology Publication No. 14-06-029, or as revised and approved by Ecology), which contains the definitions and methods for determining whether the criteria below are met: (a) Category I wetlands represent a unique or rare wetland type; are more sensitive to disturbance than most wetlands; are relatively undisturbed and contain ecological attributes that are impossible to replace within a human lifetime; or provide a high level of function. The following types of wetlands are Category I: (i) Wetlands of high conservation value that are identified by scientists of the Washington Natural Heritage Program/Department of Natural Resources; (ii) Bogs; (iii) Wetlands with mature and old growth forests larger than one acre; and (iv) Wetlands that perform functions at high levels (wetlands that score 23 points or more based on functions). (b) Category II wetlands are difficult, though not impossible, to replace, and provide high levels of some functions. Category II wetlands are those wetlands that score between 20 and 22 points based on functions. (c) Category III wetlands are wetlands with a moderate level of functions that score between 16 and 19 points based on functions. (d) Category IV wetlands are wetlands with the lowest level of functions (scoring less than 16 points based on functions) and are often heavily disturbed. Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 17 of 37 (2) Wetland buffers shall be measured perpendicular from the wetland boundary as delineated and marked in the field. Buffer widths are established as follows: Minimum Buffer Buffer Width Buffer Width Buffer Width Width (wetland (wetland scores (wetland scores 6 (wetland scores 8 scores 3 — 4 habitat 5 habitat — 7 habitat — 9 habitat Wetland Category points) points) points) points) Category I: 190 feet 190 feet 190 feet 225 feet Bogs and wetlands of high conservation value Category I: 75 feet 105 feet 165 feet 225 feet Forested and based on function score Category II 75 feet 105 feet 165 feet * 225 feet Category III 60 feet 105 feet 165 feet 225 feet Category IV 40 feet 40 feet 40 feet 40 feet [* Yellow highlight is the standard buffer width for the Panther Lake Wetland Unit as indicated by JCA, 4/26/171 (3) No wetland buffer is required for those isolated wetlands 1,000 square feet or less in total area. (4) All compensatory mitigation sites shall have buffers consistent with the buffer requirements of this section. Buffers shall be based on the expected or target category of the proposed wetland mitigation site. (5) Lighting shall be directed away from wetland buffers unless otherwise determined by the director. (6) All lots approved in a recorded subdivision or binding site plan that contain wetlands and their associated buffer in a native growth protection easement or tract may be improved pursuant to easement or tract boundaries established in the plat regardless of subsequent regulatory buffer increases or natural migration. (7) All wetland and wetland buffer boundaries shown on an approved use process decision and/or building permit shall be honored regardless of subsequent regulatory buffer increases or natural migration. (Ord. No. 15-797, § 22, 6-16-15) 19.145.430 Development within wetlands. (1) Generally. No development or improvement may be located within a wetland except as provided in this section. (2) Development within wetlands. The specific location and extent of development within a wetland must constitute the minimum necessary encroachment as determined through application of mitigation sequencing set forth in FWRC 19.145.130. The city will review and decide upon development within a wetland using process IV in Chapter 19.70 FWRC, based on the following criteria: (a) It will not adversely affect drainage or stormwater retention capabilities; (b) It will not lead to unstable earth conditions nor create erosion hazards; (c) It will not be materially detrimental to any other property in the area of the subject property nor to the city as a whole, including the loss of open space; (d) It will result in no net loss of wetland area, function or value upon completion of compensatory mitigation; (e) The project is in the best interest of the public health, safety or welfare; Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 18 of 37 (f) The applicant has demonstrated sufficient scientific expertise and supervisory capability to carry out the project; and (g) The applicant is committed to monitoring the project and to making corrections if the project fails to meet projected goals. (3) Requirements for compensatory mitigation. Compensatory mitigation shall be used only for impacts that cannot be avoided or minimized and shall achieve equivalent or greater biologic functions. Compensatory mitigation plans shall be consistent with Wetland Mitigation in Washington State — Part 2: Developing Mitigation Plans —Version 1 (Ecology Publication No. 06-06-01 lb or as revised), and Selecting Wetland Mitigation Sites Using a Watershed Approach (Western Washington) (Ecology Publication No. 09-06-32). (4) Mitigation. Acceptable methods to mitigate wetland impacts include creation, re-establishment, rehabilitation, and enhancement of in -kind wetland types within the same drainage basin that results in no net loss of wetland area, function, or value. If approved by the city, the applicant may locate a portion or all of the compensatory mitigation using alternative mitigation including, but not limited to, an approved and certified in -lieu fee program or mitigation bank, and/or advanced mitigation if it is determined that off -site, out -of -basin, and/or out -of -kind mitigation would provide a greater overall benefit to the watershed and not result in adverse impacts to the city's stormwater management system and/or wildlife habitat. Alternative mitigation methods are discretionary and may become an option following an operating agreement between the city and mitigation receiving area. (a) In -lieu fee. Credits from an in -lieu fee program approved under state and federal rules may be used at the discretion of the city and when all of the following are met: (i) The city determines that it would provide environmentally appropriate compensation for the proposed impacts; (ii) The proposed use of credits is consistent with the terms and conditions of the approved in -lieu fee program instrument; and (iii) The compensatory mitigation agreement occurs in advance of the authorized impacts. (b) Mitigation bank. Credits from a wetland mitigation bank that is certified under state rules may be used at the discretion of the city and when all of the following are met: (i) The city determines that it would provide environmentally appropriate compensation for the proposed impacts; (ii) The proposed use of credits and replacement ratios are consistent with the terns and conditions of the certified bank instrument; and (iii) The compensatory mitigation agreement occurs in advance of the authorized impacts. (c) Advance mitigation. Mitigation for projects with pre -identified impacts to wetlands may be constructed in advance of the impacts at the discretion of the city and if the mitigation is implemented according to federal rules, state policy on advance mitigation, and state water quality regulations. (5) Wetland mitigation ratios. The following are ratios for providing creation, re-establishment, rehabilitation, or enhancement of impacted wetlands. Ratios for rehabilitation and enhancement may be reduced when combined with 1:1 replacement through creation or re-establishment pursuant to Table 1 a, Wetland Mitigation in Washington State — Part 1: Agency Policies and Guidance —Version 1 (Ecology Publication No. 06-06-01 la, or as revised). Creation, re-establishment, rehabilitation, and enhancement definitions and intent shall be pursuant to Ecology Publication No. 06-06-011a, or as revised.

(v) Required wetland buffers for existing wetlands and proposed compensation areas. (vi) Plant schedule for compensation area, including all species by proposed community type and water regime, size and type of plant material to be installed, spacing of plants, typical clustering patterns, total number of each species by community type, and timing of installation. (vii) Performance standards that provide measurable benchmarks reflective of years post - installation for upland and wetland communities, monitoring schedule, and maintenance schedule. (d) Alternative mitigation plans (in -lieu fee, mitigation banks, and advanced mitigation) shall provide items (6)(a), (b)(i) and (ii) from this section, responses to subsection (4)(a), (b), or (c) of this section, and any other information deemed necessary by the city to adequately consider the alternative mitigation proposal. (7) Monitoring. Mitigation monitoring shall be required for a minimum of five years to establish that performance standards have been met. The mitigation plan shall include monitoring elements that ensure certainty of success for the proposal's natural resource values and functions. The applicant remains responsible for restoration of the natural resource values and functions if the mitigation goals are not obtained with the five-year monitoring period. Additional monitoring and corrective actions may be required by the director in order to meet goals within the approved mitigation plan. (Ord. No. 15-797, § 22, 6-16-15.) 19.145.440 Development within wetland buffers. (1) Generally. Except as allowed in this section, no development or improvement may be located within a wetland buffer. (2) Trails. The director may provide written approval for passive pedestrian recreation facilities designed in accordance with an approved critical area report and the following standards: (a) Trails are composed of pervious surfaces no more than five feet in width. Raised boardwalks and wildlife viewing structures composed of non -treated pilings may also be considered; (b) Trails are generally located parallel to the perimeter of the wetland and within the outer 25 percent of the buffer; and (c) Trails shall avoid the removal of mature trees. (3) Stormivater management facilities. The director may provide written approval for stormwater management facilities limited to stormwater dispersion outfalls and bioswales within the outer 25 percent of the buffer of category III and IV wetlands if the location of such facilities will not degrade the functions or values of the wetland. (4) Permanently altered buffer. The director may provide written approval for a buffer reduction when existing conditions are such that portions of the required buffer exist in a permanently altered state (e.g., Panther Lake Trail Wetland Rating Report By John Comis Associates (JCA) Date: 5/23/2017 Page 21 of 37 roadways, paved parking lots, and permanent structures) and do not provide any buffer function. The buffer may be reduced up to the area where the altered conditions exist. (5) Buffer averaging. The city will review and decide upon buffer averaging using process III in Chapter 19.65 FWRC, based on the following criteria that shall be added to the critical areas report: (a) The total area of the buffer after averaging is equal to the area required without averaging; (b) The buffer is increased adjacent to the higher functioning area of habitat or more sensitive portion of the wetland and decreased adjacent to the lower functioning or less sensitive portion; (c) The buffer at its narrowest point is not reduced to less than 75 percent of the required width; and (d) Unless authorized in writing by a consenting neighboring property owner, the averaging will remain on the subject property. (6) Buffer reduction ivith enhancement. Buffers may be reduced by up to 25 percent on a case -by -case basis if the project includes a buffer enhancement plan that clearly substantiates that an enhanced buffer will improve and provide additional protection of wetland functions and values. Buffer reductions may not be used in combination with buffer averaging. The city will review and decide upon buffer reductions using process III in Chapter 19.65 FWRC, based on the following criteria: (a) It will not adversely affect water quality; (b) It will not adversely affect the existing quality of the wetland or buffer wildlife habitat; (c) It will not adversely affect drainage or stormwater retention capabilities; (d) It will not lead to unstable earth conditions nor create erosion hazards; (e) It will not be materially detrimental to any other property or the city as a whole; and (f) All exposed areas are stabilized with native vegetation, as appropriate. A buffer enhancement plan, prepared by a qualified professional, shall be incorporated into the critical area report. The plan shall assess the habitat, water quality, stormwater retention, groundwater recharge, and erosion protection functions of the existing buffer; assess the effects of the proposed modification on those functions; and address the six approval criteria of this section. (7) Buffer increases. The director shall require increased buffer widths, on a case -by -case basis, when a larger buffer is necessary to protect functions, values or hazards based on site -specific conditions. This determination shall be supported by appropriate documentation showing that additional buffer width is reasonably related to protection of the functions and values of the wetland, and/or protection of public health, safety and welfare. Such determination shall be attached as permit conditions. The determination must include but not be limited to the following criteria: (a) The wetland contains habitat for species listed as threatened, endangered, candidate, sensitive, monitored, or documented priority species or habitats by state or federal agencies, and additional buffer is necessary to maintain viable functional habitat; (b) The adjacent land is susceptible to severe erosion, and erosion control measures will not effectively prevent adverse wetland impacts; or (c) The adjacent land has minimal vegetative cover or slopes greater than 30 percent.

If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? NO — go to 2 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. 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. N 0 — go to 3 YES — The wetland class is Flats I your we and can be classified as a Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at anytime of the year) at least 20 ac (8 ha) in size; Ef' e JCA report At least 30% of the open water area is deeper than 6.6 ft (2 m). details . ] 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. 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? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1, 2015 Wetland name or number PLw NO — go to 6 YES — The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at sometime during the year? This means that any outlet, if present, is higher than the interior of the wetland. [See JCA report NO —go to 7 for details.] ES — The wetland;class is Depressional <7. Is the entire wetland unit located in a very flat area with noobviousession and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO — go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated HGM class to use in rating Slope + Riverine Riverine Slope + Depressional Depressional Slope + Lake Fringe Lake Fringe Depressional + Riverine along stream withi ion De ressional + Lake Fringe Depressional Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have more than Z HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Bachelor of Science, Environmental Bioengineering, University of Washington, Seattle, 1973 EMPLOYMENT HISTORY.• Consoer, Townsend & Associates, junior engineer, 1974-77 Pierce County Public Works, civil engineer II, planning & drainage engineer, 1977-89 John Comis Associates, principal as a sole proprietorship, 1989-2005 JCA, Incorporated (Inc.), 2005 to 2010 JCA, Limited Liability Corp. (LLC), 2010 to present QUALIFICATIONS. Mr. Comis has worked a total of 43 years in both public sector surface water management (15 years) and private sector wetland consulting (28 years). Mr. Comis' education, research, and experience combine the highly technical fields of water biology and water engineering. John has applied his experience and knowledge to preparing wetland delineations and mitigation plans for clients for all manner of large and small-scale projects. Private projects have dealt with all aspects of wetland consulting including identification, delineation, mitigation, restoration, and simply setback avoidance for new developments. Wetland projects include over 800 sites and developments in Pierce, King, Kitsap, Lewis, Thurston and Grays Harbor Counties, including work that was done within the City's of Algona, Auburn, Bellevue, Bothell, Bonney Lake, Buckley, Enumclaw, Edgewood, Federal Way, Fife, Fircrest, Issaquah, Kent, Lakewood, Milton, Olympia, Ocean Shores, Pacific, Puyallup, Renton, Sumner, Tacoma and University Place. John has also assisted clients with flood plain and drainage studies including runoff modeling and backwater analysis. Public sector experience involves many aspects of drainage and surface water management from basin level planning to site specific analysis and design. John has experience with computer models used for estimating runoff, routing stream flows, calculating flood plain elevations and sizing retention/detention facilities. On many projects, John has worked closely with soil scientists, fishery biologists, civil engineers, surveyors, and regulatory agency staffs at all levels of government. He has frequently been involved with interdisciplinary project teams at both the planning and implementation stages of project development. In academic research, John directed two National Science Foundation projects for an interdisciplinary research team on Kelsey and Coal Creeks, King County, Washington while he was attending the University of Washington. He has conducted drainage and flood studies at all levels of project development. This has provided opportunities to put theory into "on -the -ground" applications for stream studies, FEMA flood plain analysis and mapping, and writing flood plain management regulations together with other aspects of surface water management.

Surface Water Management Project Engineer Subject: Panther Lake Park Trail Technical Information Report (TIR) O�r _ W h �J r p �Afr� si2gt q c�'� y '(0NAG The purpose of this memorandum is to describe the stormwater requirements for the proposed Panther Lake Park Trail. In summary, flow control and water quality requirements will be provided by using a combination of pervious pavement with infiltration, and dispersion. Project Overview The proposed Panther Lake Park Trail improvements involve constructing a new driveway, 26-stall parking lot, and six-foot wide crushed rock trail to connect to the existing social trail. The existing social trail will be improved by grading and providing a new crushed rock surface, extending the trail to connect to the BPA trail, and providing a new pedestrian bridge. The project designer is David A Clark Architects, PLLC. Existing Conditions The project site is owned by the City of Federal Way and located at approximately 500 SW Campus Drive in Federal Way, Washington within the Hylebos Creek drainage basin. The site is situated between SW Campus drive to the south, the King County Aquatic Center to the west, the Federal Way Little League baseball complex to the east, and the BPA trail to the north/west. A map of the site and existing facilities is provided in Figure 1. In existing conditions, the proposed parking lot site is undeveloped and covered with deciduous trees. The proposed social trail expansion is currently a dirt path that includes the crest of the Panther Lake Dam and circles the perimeter of Panther Lake. Panther Lake is a natural closed depression that was expanded with the construction of the Panther Lake and Ball Field dams in 1993. The proposed parking lot is rectangular in shape and the social trail improvements are linear and meandering. The proposed parking lot site generally slopes from south to north toward Panther Lake, and the grade of the proposed trail improvements varies along the alignment.- Existing storm drain features are shown in Figure 1. Additional discussion of the existing conveyance network and downstream facilities is described under Core Requirements #1 and #2. Page 1 of 9 Proposed Conditions The proposed parking lot is approximately 13,390 square feet, including the parking lot, connection to trail and driveway entrance. The full hardened surface will be constructed with pervious concrete and provide sufficient storage to infiltrate all runoff. A layout of the proposed improvements is provided in Figure 2. Proposed slopes will be less than 5% for the entire parking lot. No offsite impervious area will be routed to the pervious pavement. The proposed trail improvements extend for approximately 4,000 linear feet and will be a crushed gravel surface with vegetated side slopes that disperse into the native vegetation. A map of the proposed trail improvements is provided in the permit drawings in drawing G-106. Design Criteria The stormwater requirements for this project are from the 2016 King County Surface Water Design Manual (KCSWDM) and the City of Federal Way Addendum (CFW Addendum) to the KCSWDM dated January 8, 2017. The project site is subject to Conservation Flow Control and Enhanced Basic Water Quality requirements. Drainage Review Requirements The project proposes more than 7,000 square feet of land disturbing activity and is subject to stormwater and water quality reviews per the CFW Addendum. Soils The National Resources Conservation Service (NRCS) Soil Survey Map for King County lists the site soils surrounding the parking lot as InC (Indianola loamy sand), defined as loamy sand where the depth to restrictive features is usually more than 80 inches and the capacity of the most limiting layer to transmit water is high. InC is identified as an NRCS hydrologic soil group "A". NRCS Soil Survey Maps show the social trail alignment includes AgD (Alderwood gravelly sandy loam) and EwC (Everett-Alderwood gravelly sandy loams). AgD is definied as a gravelly sandy loam where the depth to restrictive features is between 20 and 39 inches and the capacity of the most limiting layer to transmit water is very low to moderately low. EwC is defined as a gravelly sandy loam where the depth to the restrictive feature is more than 80 inches and the capacity of the most limiting layer to transmit water is high. AgD and EwC are defined as NRCS hydrologic soil groups "C" and "A" respectively. A geotechnical report was prepared for this project by AECOM and City staff collected two supplemental soil samples to test for cation exchange capacity and percent organic content. Infiltration testing was performed using a small scale pilot infiltration test (PIT) at the proposed infiltration facility and measured infiltration rates were between 4 in/hr and 7 in/hr. Using the procedure outlined in equation 5-11 in Section 5.2.1 of the KCSWDM, the design infiltration rate is calculated by: Idesign = Imeasured X Ftesting x Fgeometry x Fplugging Where: Imeasured = the measured infiltration rate (used 4 in/hr) Ftesting = the testing correction factor (0.5 for small and large scale PIT) Page 2 of 9 Fgeometry = 4W + 0.05 Where: D = depth from the bottom of the proposed facility to the maximum wet -season water table or nearest impervious layer, whichever is less (> 5 ft from Geotech report) W = width of the facility ("'209 ft) __> Fgeometry = 0.15 (use 0.25 because value must be between 0.25 and 1.0) Fpiugging = Long term reduction in rate due to soils plugging (use 0.8 for loamy sands) I design = 0.40 in/hr Core Requirements Core Requirement #1 — Discharge at the Natural Location Under Existing conditions, the parking lot area is undeveloped and vegetated. Runoff infiltrates, evaporates, transpires, or eventually runs off into Panther Lake. The Lake is a closed depression that retains water up to an overflow elevation where it discharges through the dam's outlet works downstream to the West Hylebos. The proposed improvements will continue to discharge to Panther Lake. Core Requirement #2 — Offsite Analysis The study limits of this Level 1 offsite analysis extend % mile downstream from the project discharge point. The Hylebos Basin Plan, City mapping, NRCS soil surveys and citizen action request databases were reviewed as part of the analysis. The Panther Lake Dam project was completed in 1993 and increased the capacity of the existing Panther Lake natural depression. Improvements included raising the berm, improving the spillway and constructing the ballfield dam as a structure in series with the Panther Lake Dam. King County maps show that the east and west sides of the Panther Lake parcel are mapped as erosion hazard areas, that the site's susceptibility to groundwater contamination is medium to high, and that the site is within wellhead protection areas with five to ten years of travel time (capture zones 2 and 3). The site is outside of the Wellhead capture zone 1. Runoff draining to the lake that rises to the dam's primary spillway enters the piped outlet works and is conveyed in a 27" corrugated metal pipe (CMP) that drains under the existing ball fields, under the ballfield dam and into the existing City maintained storm drain system. The storm drain system drains south through the Win -Co Parking lot, crosses SW Campus Drive and enters an open channel south of the intersection of SW Campus Drive/S348th Street and 15t Ave S. When runoff draining to the lake rises up to the gabion overflow spillway, water is impounded behind the ballfield dam and drains through the ballfield dam outlet works into the same storm system draining the Panther Lake Dam primary spillway. The City's citizen reporting database and work order tracking system shows no flooding or nuisance water issues downstream, along the length of the existing storm drain, and at the storm drain outlet. Page 3 of 9 No known issues need to be addressed with this project and no known issues will be made worse with the completion of this project. Core Requirement #3 — Flow Control The project is located in a Conservation Flow Control area, requiring improvements to meet historic forested condition flow durations. However, all target areas for the project will either infiltrate with pervious pavements (the entrance and parking lot) or disperse (along the trail improvements). Analysis of the proposed parking lot pervious pavement is provided in Attachment 1. No new flow control facilities will be provided. Core Requirement #4 — Conveyance System No new conveyance system will be provided because the parking lot will be pervious concrete with an 8 inch thick aggregate layer reservoir course and the social trail improvements will disperse. An underdrain is not proposed for the pervious paving parking lot. Core Requirement #5 — Erosion and Sediment Control Erosion control plans will be prepared for this project based on the thirteen measures outlined in section 1.2.5 of the KCSWDM. 1. Clearing Limits are shown on the plan to minimize the construction footprint and existing vegetation will be preserved to the maximum extent practical. 2. Cover measures will be employed for all soil and material stockpiles and disturbed areas not receiving temporary or permanent stabilization within one week during the dry season or within two days during the wet season. 3. A silt fence will be used at the parking lot and entrances in combination with straw wattles. 4. Traffic area stabilization will be provided by stabilized construction entrances and any material tracked onto adjacent paved streets will be swept and removed. S. Temporary sediment retention will be provided by the perimeter silt fence and straw wattle BMPs. Storm drain inlet inserts will also be installed in adjacent catch basins within SW Campus Drive. 6. No surface water will need to be collected during construction of the project. 7. Construction dewatering will not be needed. 8. Dust control will be provided by water application as necessary at the minimum rate necessary to prevent dust pollution. 9. Flow control is not required or provided by this project. 10. - 13. Pollutants will be controlled, flow control BMPs will be protected and maintained, and the erosion and sediment control plan will be actively managed throughout the project. In addition, the proposed pervious surfaces will be protected from sediment contamination following installation. Page 4 of 9 Core Requirement #6 — Maintenance and Operations Manual Maintenance and operations of the proposed facility will be conducted consistent with Appendix A of the KCSWDM. Core Requirement #7 — Financial Guarantees and Liability The project is a City Parks and Recreation project to be constructed on a City owned parcel. Financial guarantees will not be required. Core Requirement #8 — Water Quality A water quality review is required per the CFW Addendum because the project proposes more than 7,000 square feet of land disturbing activity. The project is in an enhanced basic water quality treatment area and target surfaces include new pollution generating impervious surface (PGIS), pollution generating pervious surface (PGPS), existing impervious surfaces added since January 8, 2001, and replaced PGIS and PGPS. The proposed parking lot is approximately 13,390 square feet, exceeding the 5,000 square foot threshold for'PGIS. Since water quality is required, the CFW Addendum requires that the entire site must be brought up to water quality standards. Water quality for the site will be accomplished by using pervious pavement and infiltration at the proposed parking lot and dispersion along the social trail improvements. The proposed infiltration location is located in a wellhead protection area 3 (10-year travel time) and outside of erosion hazard areas identified in previous sections. City staff collected soil samples to verify the cation exchange capacity (CEC) and percent organic content of the existing soil and found it suitable for water quality treatment. Two samples were taken each for CEC and percent organic content, one each at the east and west ends of the proposed parking lot. Values for CEC were 190 and 200 for east and west respectively, and percent organic content values were 7.1% and 14%. Both sample locations exceed the required CEC of 5 or greater and percent organic content of 1% or greater. A full report of laboratory testing results is provided in Attachment 2. Special Requirements Special Requirement 1— Other Adopted Area -Specific Requirements There are no adopted area -specific requirements that apply to this project beyond what is required by the KCSWDM and the CFW Addendum. Special Requirement 2 — Flood Hazard Area Delineation Special requirement 2 does not apply to this project because no flood hazard areas exist on or adjacent to the project site. Special Requirement 3 — Flood Protection Facilities Special requirement 3 does not apply because the project will not rely on or modify an existing flood protection Facility. Page 5 of 9 Special Requirement 4 —Source Controls Source controls will not be required for this project because there is no commercial building or commercial site development permit. Special Requirement 5 — Oil Control Special requirement 5 does not apply because the proposed park improvements do not meet any of the KCSWDM definitions for a high use site.

A site plan is shown on Figure 1. The field investigation and infiltration testing activity was conducted on December 7, 2017, by a representative from AECOM, with test pits excavated by and infiltration water supplied by the City of Federal Way. 2.0 PROPOSED CONSTRUCTION The proposed project is located near the southwest corner of Panther Lake where the new 6- foot wide by 50-foot long east -west oriented pedestrian bridge will join the existing BPA Trail and the Panther Lake Trail. The bridge will be located roughly 120 feet north of the existing SW Campus Drive, and will be situated between the existing Weyerhauser King County Aquatic Center near the west side and an existing little league baseball facility near the east side. The proposed construction also includes an asphalt pavement parking lot for which the infiltration test was performed. 3.0 SITE CONDITIONS 3.1 GEOLOGIC SETTING The geologic setting for the project area delineated in Geologic Map of the Poverty Bay 7.5' Quadrangle, King and Pierce Counties, Washington, is recessional outwash deposits, bordering on peat and alluvium due to the proximity of Panther Lake. Recessional outwash deposits are stratified sand and gravel, moderately well sorted to well sorted, and less commonly silty sand and silt. Recessional outwash generally may be loose to dense, and has a relatively high permeability but may be water bearing. 3.2 SURFACE CONDITIONS The ground surface in the area of the proposed pedestrian bridge is lightly vegetated on a pre-existing walking trail and is on the top of a roughly 10-ft high moderately inclined slope down to a small drainage channel sloping towards the lake (See Photo B.2 in Appendix B). Flow was not observed in the channel during the December 7, 2017 investigation. 3.3 SUBSURFACE CONDITIONS Subsurface soil and groundwater conditions were assessed through a combination of exploration by AECOM and by a review of previous subsurface investigations in the general area performed by others. The geotechnical report by Landau Associates (2013) describes some prior subsurface explorations in the area. Page 2 J:IDCYProjeclsl WfRlPanther Lake Ped BridgelReportlReporNPanlher Geotech Rpt 01-17-18F/N.doc Two test pits were excavated by AECOM on December 7, 2017, to a depth of 7-8 ft at locations shown on Figure 1. Subsurface conditions are approximately as indicated below: Test Pit 19:42 to 10.00 hours): Test Pit 1 (TP-1) was excavated to a depth of 7 ft. Soft to very soft clayey silt was encountered from the ground surface down to a depth of 4 ft, becoming medium stiff to stiff from 4 to 5 ft. At 5-7 ft, medium dense to dense silty sand with gravel was encountered and excavation was concluded, as the backhoe appeared to be excavating with some difficulty indicating favorable soils just short of the maximum target depth of excavation (8 ft). See TP-1 in Photo B.1 in Appendix B. Test Pit 2 (10:33 to 11:18 hour,: Test Pit 2 (TP-2) was excavated to the target excavation depth of 8 ft. Fill consisting of loose to medium dense silty gravel with sand and cobbles was encountered from the ground surface down to a depth of 3 ft. At 2.5 to 3 ft, a boulder size (approximate 2 to 2.5 ft diameter) piece of concrete rubble was encountered and removed by the back hoe (see photos). At 3 to 7.5 ft, medium dense well -graded gravel with sand was encountered. At 4 ft, a thin layer of black ash, appearing to be the pre-existing native surface, was encountered (see photo). At 7.5 ft, dry, dense slightly cemented silty gravel with sand and cobbles was encountered. The excavation was terminated at a depth of 8 ft. See TP-2 in Photos B.3-B.5 in Appendix B. 3.4 GROUNDWATER Groundwater was not encountered during excavation of the test pits. Groundwater was noted to have been encountered in an investigation by others in October 1991 at approximately Elevation 248 at a location to the west and north of Panther Lake (Landau, 2013). This corresponds approximately to the water level in Panther Lake with is approximately 0.1 mile away from the project location. Groundwater at Elevation 248 is anticipated to be well below the location of the footings during construction. The ground suface at the footing locations is expected to be at approximately Elevation 263 to 264. 4.0 FIELD AND LABORATORY TESTING A geotechnical engineer from AECOM was present during the field exploration on December 7, 2017, to observe the excavation by the City of Federal Way backhoe operator, retrieve representative soil samples for subsequent visual classification and laboratory testing, and prepare descriptive field logs of the explorations. Ambient temperatures ranged from about 30 to 40°F. Soils were classified in general accordance with the ASTM International (ASTM) Designation D 2488-93, "Standard Recommended Practice for Description of Soils (Visual -Manual Procedure)." The Unified Soil Classification System (USCS) was used to classify the soils encountered in the soil borings. The test pit logs in Appendix A of this report represent our interpretation of the soil profiles in the test pits. The soil classifications have been incorporated into the soil descriptions on the boring logs presented in Appendix A. Page 3 J:IDCSIProjectslWPRlPantherLake Ped BridgelReportlReporilPantherGeoteclr Rpt 0I-17-I8FIN.doc Pocket penetrometer readings were taken, which represents the approximate unconfined compressive strength of the material, for the native clay/silt soils were taken on the samples collected from Test Pit 1 during this investigation. The results of these tests are reported on the attached boring logs at the corresponding sample depth. This value is an empirical parameter that provides a means for evaluating relative density, or compactness, of granular soils, and the consistency, or stiffness of the cohesive soils. These values are provided at the appropriate depths on the boring logs presented in Appendix A. After the field investigation, grain size distribution testing was performed in general accordance with ASTM Designation D 422, "Standard Method for Particle -Size Analysis of Soils." For this study, only sieve analyses were performed for the percentage of fines passing the No. 200 sieve. Grain size distributions are used to assist in classifying soils and evaluating soil behavior when excavated, and to provide correlation with other soil properties, including permeability, capillary action, and sensitivity to moisture. The test results are shown on the logs of borings at the depth of the sample. As indicated on the TP-1 log and shown in Appendix A, sieve analyses on samples at 3-4 ft and 5 ft indicate the percent fines (passing the #200 sieve). 5.0 CONCLUSIONS AND RECOMMENDATIONS 5.1 SOIL PARAMETERS - GENERAL Estimates of soil parameters for each of the soil strata encountered at the site are provided in Table 1. The parameters have been estimated using a combination of measured field and laboratory data together with published data on similar soils. It should be noted that in most cases the values listed in Table 1 are intended to represent average or slightly on the conservative side of average conditions. Natural variations in stratigraphy and soil parameters are expected throughout the site, and Table 1 values may not be strictly representative of all locations.

The likelihood of liquefaction or lateral spread appears to be insignificant considering the conditions and soil profiles encountered in the test pits. Liquefaction susceptibility is generally very low in the project area according to liquefaction mapping (Palmer, 2004). "Liquefaction is a phenomenon in which strong earthquake shaking causes a soil to rapidly lose its strength and behave like quicksand. Liquefaction typically occurs in artificial fills and in areas of loose sandy soils that are saturated with water" (Palmer, 2004). The geotechnical-related parameters to be used for seismic design in accordance with 2015 IBC provisions are evaluated as described in Section 1613.3 of the 2015 IBC Code. The spectral response accelerations for the "Risk -Targeted Maximum Considered Earthquake" (MCER) were obtained from the USGS website using latitude of 47.294 degrees and longitude of-122.342 degrees. The Site Class is selected using the definitions in Chapter 20 of ASCE 7-10 considering the average properties of soils in the upper 100 feet of the soil profile at the site. Considering the anticipated average properties of the soils (SPT N-Values) in the upper 100 feet of the soil profile at the site, Site Class D ("Stiff Soil") was selected in Table 20.3-1 (ASCE 7-10). The site coefficient values, obtained from Section 1613.3.3 of the 2015 IBC, are used to adjust the mapped spectral response acceleration values to get the adjusted spectral response acceleration values for the site. The recommended Site Coefficient values for Site Class D are presented in Table 2. The site coefficient values, obtained from Section 1613.3.3 of the 2015 IBC, are used to adjust the mapped spectral response acceleration values to get the adjusted spectral response acceleration values for the site.

An allowable soil bearing pressure of 3,000 psf is anticipated if the footings are placed in the medium dense to dense native silty sand or gravel anticipated at approximately Elevation 260 (5 feet below the test pit location). Settlement is estimated to be less than 0.5 inches for up to a 10- foot long and up to 6-foot wide footing. The settlements are expected to be primarily elastic in nature, occurring essentially simultaneous with the application of load. No substantial long term settlements are anticipated. 5.4 INFILTRATION The scope of the work was to perform a small-scale pilot infiltration test (PIT) at the location shown on Figure 1. The infiltration test pit was excavated by City of Federal Way personnel and consisted of a 3- foot deep test pit, approximately 4-feet by 4-feet in area at the bottom of the pit and 4.5-feet by 4.5-feet at the surface. The surface soils contained roots and brown topsoil. The soil in the test pit between 1 and 3 Page 6 J: I DCSI Projecfs1 WTMPanther Lake Ped Bridge)Report I Report I Panther Geotech Rpt 01-17-18FIN.doc feet below ground surface was visually determined to be moist, light brown, well -graded, subrounded gravel and sand with trace silt (see Photo B.6 in Appendix B). No groundwater was encountered in the infiltration test pit. Pre-soak period: The pit was excavated on the morning of December 7, 2017. Prior to starting the test, a measuring rod was installed firmly in the center of the pit for water level measurements. The water was sprayed with a washer gun into a 5-gallon bucket and allowed to overflow into the pit in order to prevent erosion of the pit bottom or walls. The pre-soaking of the PIT was started at 09:25 hours and continued through 3:07 hours. The infiltration rate was calculated a few times during the pre-soak period. It was noted at 9:30 hours after the washer gun was removed to increase the flow rate, that the water got up to 3 to 4 inches and, after turning off the water, within one minute the water went down 2 inches (60 in./hr). By 9:35 hours (10 min after pre-soak commenced), 40 gallons had already been added to the pit. The volume of water available (175 gallons) and the infiltration rate only allowed the level of the water in the pit to reach 8-9 inches, and by 10:27 hours, the water level was down to about 6 inches. It became clear that a larger volume water tank was needed. By 11:45 hours, a 400-gallon water tank was brought in, and the pit filling for the pre-soak recommenced; by 11:57 hours, the pit was filled up to 12 inches. At 11:59 hours, the water was turned off again to check the infiltration rate over 2.5 minutes, and the rate was calculated as 12 in./hr. The water was turned back on and the level brought up to 18 inches by 12:23 hours, at which time the water was turned off until the level dropped down to 12 inches. The calculated infiltration rate over this period was 10 in./hr. The flow rate through the hose was calculated to be 7.5 to 7.9 gallons per minute by measuring how long it took for a 5 gallon bucket to be filled up (was measured twice). Steady-state period. Between 13:06 and 14:20 hours, water from the 400-gallon tank continued to be poured into the pit in an attempt to keep the head at about one foot. It was finally determined after several changes of flow rate and at a final head of 10.75 inches that a hose flow rate of 1.0 gallon per minute (equates to an infiltration rate of 6 inches per hour) was required to keep the head constant. Falling head period. Between 14:20 and 14:30 hours, as much of the remaining water left in the 400- gallon tank was directed into the pit prior to the departure of the City of Federal Way personnel driving the water truck. Roughly 50 to 100 gallons of water were left in the tank when the water was shut off at 14:30 hours. At 14:30 hours (when the water was turned off), the level of water was measured to be 16 inches in the pit. Between 14:30 and 16:07 hours, the water was allowed to drop and the following data were recorded: Table 3: Pilot Infiltration Test Results Time of Measurement Elapsed Time min Depth (in.) Infiltration Rate (in./hr)* 14:30 0 16 14:52 22 13.5 7 15:07 37 12 6 15:22 52 10.5 6 15:37 67 9.25 4 15:52 82 8 5 16:07 97 7 4 Page 7 J: I DCSI Projeclsl WfRI Pan[her Lake Ped Bridge) ReportI Report I Panlher Geotech Rpt 01-17-18FINdoc �1 *Note that these values were calculated over slightly different time increments (with an accuracy of +/-1 min), to the nearest 0.25 inch. The AECOM geotechnical engineer left the site shortly after 16:07 hours. According to City of Federal Way personnel, the infiltration pit was completely drained when observed it the morning following the PIT. 5.5 EARTHWORK CONSIDERATIONS AECOM recommends the presence of an AECOM geotechnical engineer during earthwork activities to perform construction monitoring, subgrade inspection, materials inspection, and verification and documentation that the footing subgrades meet the design requirements. The time that the footing subgrades are exposed should be minimized, and the footing subgrades should be protected after excavation from erosion. Construction during wet weather is highly discouraged with the understanding that a high percentage of fines would make the soils vulnerable to deterioration. Erosion control efforts during construction should be adopted, and Best Management Practices applied as necessary including erecting silt fencing that is properly keyed into the base, covering or removing excavated soils, and applying final seeding upon completion of construction. The footing subgrade should be exposed by excavation down to suitable granular bearing soils which were encountered at the proposed east footing in TP-1 at about 5 ft and at the proposed west footing in TP-2 at about 3-4 ft. Footings should be embedded at least 1.5 feet for frost protection. Proper preparation of subgrades supported on the existing soils should consist of a backhoe-mounted hydraulic vibratory compactor (Hoe pac) or walk behind (what kind?), producing a firm and unyielding subgrade surface. Where an unyielding surface cannot be readily obtained, overexcavation, and recompaction or replacement with suitable well graded structural fill or excavated fill may be required at the direction of the geotechnical engineer. Likewise, if the footings are to be placed at a higher elevation than the bottom of the excavation, suitable fill may be placed up to the footing bottom. The newly exposed subgrade, or on -site (excavated) or imported structural fill should be compacted to produce a firm and unyielding surface. Although the need for imported structural fill is not anticipated, if it is used, imported structural fill should consist of well graded granular soil, or other well graded natural or crushed products, and should be compacted in 6 to 8 inch lifts. The soils at the location of the test pits should be considered Type C soil from the standpoint of OSHA/WISHA regulations for trenching and shoring. This means that temporary cuts greater than 4 feet deep should be no steeper than 1.5 Horizontal to 1 Vertical (1.5 H:1 V). Surface compaction of the slopes may be needed to control localized sloughing. 6.0 REFERENCES Booth, D. B., Waldron, H.H., and K.G. Troost (2004).
