PROJECT INFORMATION AND BACKGROUND Name of Project: Washington State Department of Transportation (WSDOT) Triangle Project City File No: 09-104380-00-UP Requested Decision: Applicant requests a Process IV `Hearing Examiner' decision pursuant to Federal Way Revised Code (FWRC) Chapter 19.70. WSDOT issued an Environmental Determination of Nonsignificance (DNS) pursuant to State Environmental Policy Act (SEPA) procedures on May 11, 2007. Staff Recommendation: Approval with Conditions Summary of Proposal: Clearing and grading activities; wetland mitigation; permanent and temporary wetland buffer intrusions; and stream culverting/relocating associated with the replacement of Interstate-5 and SR 18 interchange cloverleaf ramps and new direct connection fiom westbound SR 18 to SR 161 in the vicinity of South 3591h Street (Exhibit A). Site Location: WSDOT right-of-way within the Federal Way city limits as shown on the vicinity map (Exhibit B). Portions of site work will take place on several private parcels (Exhibit C)- Wetland compensatory mitigation site is proposed at a WSDOT single-family zoned parcel located at 933 South 364`h Street (Exhibit D). Applicant: Allison Hanson, Director of Environmental Services, ESO Mega Projects WSDOT, 999 3'-d Avenue, Suite 2424, Seattle, WA 98104 Owner: WSDOT Comprehensive Plan & Zoning Designations: WSDOT right of way, WSDOT owned and privately held parcels zoned Cominercial Enterprise (CE). Compensatory mitigation site is located within a single-family medium density residential RS35.0 zoning district. Key Dates: Master Land Use application submitted December 1, 2009 Application determined complete December 17, 2009 Notice of application, December 19, 2009 (Exhibit E) Notice of public hearing, March 20, 2010 (Exhibit F) Staff Representative: Associate Planner Matthew Herrera, 253-835-2638 WSDOT Triangle Project Pile 409-104380-00-UP / Doc ID 52650 Hearing Examiner Staff Report Page 1 of 17 11. PROCESS IV ADMINISTRATION The Master Land Use (MLU) application contains multiple components. The FWRC requires the following review process for the applicant's requested activities 1. Stream Relocation — Process IV Hearing Examiner Decision 2. Culverts — Process III Project Approval 3. Intrusion into Stream Setback (Essential Public Facility) — Director Approval 4. Improvements within Regulated W etland — Process IV Hearing Examiner Decision 5. Improvements within Regulated Wetland Buffer (Essential Public Facility) — Director Approval Pursuant to FWRC 19.70.010, if a Process IV request also includes activities which require multiple review processes, the entire proposal will be decided upon using Process IV if it is determined that it will result in more efficient decision making. As analysis for each component can be combined into one document, staff finds separate permitting for each of the five above - referenced activities would provide no benefit to the city or the applicant; therefore, the entire proposal shall be decided upon using Process IV Hearing Examiner Decision. III. ENVIRONMENTAL REVIEW The proposed improvements and activities are not categorically exempt from the threshold determination process pursuant to the State Environmental Policy Act (SEPA) Rules as identified in Washington Administrative Code (WAC) Chapter 197-11 WSDOT, acting as Lead Agency, issued a Determination of Nonsignificance (DNS) on May 11, 2007 (Exhibit G). No comments or appeals on the DNS were submitted. Staff finds the analysis from the 2007 DNS valid for the current proposal. IV. COMMENTS RECEIVED ON MASTER LAND USE APPLICATION No comments on the Process IV application have been received as of the date of this staff report. Process IV administration rules allow any person to submit written comments anytime up to the date of the public hearing and allow any person to provide verbal comments during the hearing. V. KEY ELEMENTS OF TIIE ENVIRONMENTAL IMPACTS/MITIGATION As context for the Process IV request, the following is an outline of the key elements of the environmental impacts and mitigation as a result of the roadway improvements 1. Abandonment and filling of 495 lineal feet of a designated minor stream and relocation of the stream; 2. Three culvert extensions totaling 185 lineal feet and one new box culvert measuring 65 lineal feet; 3 Temporary intrusions of 1.29 acres into stream setback areas for construction activities associated with the roadway project; 4. Permanent intrusions of 4.64 acres into stream setback for new roadway and appurtenances; 5. Temporary intrusions of 0.6 acres into wetland buffer areas for construction activities associated with the roadway project; 6. Permanent intrusions of 1.05 acres into wetland buffer areas for new roadway and appurtenances; 7. Permanent intrusions of 0.23 acres into regulated wetlands; and 8. Off -site compensatory mitigation site of 3.37 acres that includes wetland creation/ enhancement, wetland buffer enhancement, and creation/enhancement of stream habitat. WSDOT Triangle Project File 409-104380-00-UP I Doc ID 52650 Hewing Exantiner Staff Report Page 2 of 17 VI. GENERAL CHARACTERISTICS OF SITE AND VICINITY The subject area is within the WSDOT right-of-way Interstate-5 corridor between South 336"' Street and State Route 161; WSDOT right-of-way within State Route 18 between Weyerhaeuser Way and the Interstate 5 clover leaf, two parcels commercial zoned properties owned by WSDOT; and three private parcels (Exhibit C) abutting the WSDOT right-of-way. Areas abutting the WSDOT right-of-way where the proposed construction activities will take place contain Multi -Fancily, Commercial Enterprise, and Corporate Park comprehensive plan/ zoning designations. Current uses abutting the project area include retail, office, church, vacant private parcels, and vacant parcels owned by WSDOT. V11. DESCRIPTION OF IMPACTED CRITICAL AREAS As shown in the applicant's wetland mitigation plan (Exhibit H, Page 18) and stream mitigation plan (Exhibit I, Page 9), the following critical areas will be impacted due the Triangle Project improvements. 1 East Branch Hylebos Creek (as identified by the city's critical areas inventory): Tributary 0016 — Impacted areas are located east of the Interstate 5/State Route 18 clover leaf. The city has identified the tributary a major steam; although, fish do not currently inhabit the impacted reach due to man-made blockages downstream. The tributary remains a major steam (fish bearing) as it does not contain natural fish barriers. Tributary 0016A — Impacted areas are adjacent to Interstate-5 between South 336"` Street and South 360'' Street. The city's critical areas inventory has identified the tributary a major stream. The applicant has provided analysis (Exhibit K) that a permanent natural blockage exists in the form of inadequate flows; therefore, the city has reclassified the watercourse within the construction area as a ininor steam (non -fish bearing). 2. Wetlands (as identified by the applicant's wetland report); Wetland M— Located east of the Interstate-5 clover leaf and abutting the State Route 18 westbound lane. Wetland M is an approximately 1.16 acre scrub/shrub and forested wetland. The city's wetland rating is Category II with a 100-foot buffer. Wetland. N— Located east of the Interstate-5 clover leaf and abutting the State Route 18 westbound lane. Wetland N is an approximately 0.20 acre scrub/shrub wetland. The city's wetland rating is Category III with a 25-foot buffer. Wetland AB — Located east of southbound Interstate-5 near South 360"' Street. Wetland AB is an approximately 0.42 acre emergent and scrub/shrub wetland. The city's wetland rating is Category II' with a 100-foot buffer. Wetland K — Located north of the State Route 18 on -ramp near Weyerhaeuser Way South. Wetland K is an approximately 0.13 acre scrub/shrub wetland. The city's wetland rating is Category III with a 25-foot buffer. 1 Staff disagrees with the applicant's rating of Wetland AB as FWRC 19.175.020(l)(b) states wetlands containing two or more wetland classes (scrub/shnib and emergent) and do not exhibit characteristics of a Category I wetland are classified as Category II. WSDOT Triangle Project File 409-104380-00-UP / Doc ID 52650 Hearing Examiner Staff Report Page 3 of 17 Wetland P — Located west of southbound Interstate-5 near South 336Street. Wetland P is an approximately 1.91 acre emergent and scrub/shnib wetland. The city's wetland rating is Category I1 with a 100-foot buffer. Wetland U — Located within the southwest clover leaf. Wetland U is an approximately 0.13 acre scrub/shrub wetland. The city's wetland rating is Category III with a 25-foot buffer. VIII. DESCRIPTION OF PROCESS IV REQUEST The Triangle Project will rebuild the Interstate-5 and State Route 18 interchange by replacing two of the cloverleaf ramps with a westbound State Route 18 to southbound Interstate-5 flyover ramp and eastbound State Route 18 to northbound Interstate 5 flyover ramp. The project will also build a new direct connection frorn westbound State Route 18 to State Route 161 in the vicinity of South 359`h Street. Several wetlands and two tributaries to the East Branch Hylebos Creek will be affected due to roadway expansions and widening associated with the Triangle Project. Stream relocation, culverting, and wetland encroachment will be a necessary component of the project. To mitigate the environmental impacts of the project, the applicant has purchased a parcel within the same drainage basin to perform wetland and stream habitat mitigation. Note — Staff has partitioned each of the applicant's requests and provided separate analysis (findings) and decisional criteria (conclusions) for each item. Conclusions are based on individual decisional criteria provided in the city's Critical Areas Ordinance (CAO) and codified in FWRC Title 19. The overall Process IV decisional criteria (conclusions) are located in Section XVI of this report. IX. ANALYSIS OF STREAM RELOCATION REQUEST AND DECISIONAL CRITERIA PURSUANT TO FWRC 19.165.020 Improvements for the proposed State Route 18 to State Route 161 direct connection will require the abandonment and filling of 495 lineal feet of Tributary 0016A. The applicant is proposing to relocate the stream section west of the existing channel. Findings & Conclusions The following analysis and decisional criteria is provided in accordance to the relocation section of the city's CAO as codified in FWRC 19.165.020. FWRC 19.165.020(3)(a) — The creation of a natural meander pattern. As shown in Exhibit J, the proposed relocation of Tributary 0016A will result in an approximately 580-lineal foot channel meandering in a southwesterly direction prior to entering a culvert beneath the newly created roadway section. FWRC 19.165.020(3)(b) — The formation of gentle side slopes, at least two feet horizontally to one foot vertically, and the installation of erosion control features for stream side slopes. 2H:1 V side slopes are provided as shown on the right and left meander cross -sections (Exhibit J). It will be necessary to clear existing vegetation on both sides of the newly created channel to accommodate the 2:1 side slopes. WSDOT Ttiangle Project File #09-104380-00-UP I Doc ID 52650 14caring 171xanfiner Staff Report Page 4 of 17 Erosion controls for the stream side slopes include amended soil and coin matting. Construction of the new channel and installation of the erosion control materials will occur prior to any water being diverted. FWRC 19.165.020(3)(c) — The creation of a narrow subchannel, where feasible, against the south or west bank. As the existing stream does not contain a subchannel and is bound by native vegetation as well as a future roadway, the creation of a narrow subchannel is not feasible with the current proposal. FWRC 19.165.020(3)(d) — The utilization of natural materials, wherever possible. Large woody debris (LWD), coir matting, and new landscaping is proposed within the relocated corridor. As shown on the relocation plan (Exhibit J) and detailed in the stream mitigation plan (Exhibit I, Page 36), LWD with and without root boles will be placed along glide and meander locations along the channel to increase habitat diversity. Coir matting derived from coconut husks will provide erosion control for the stream banks. Native trees and shrubs will be planted in the relocated stream buffer area providing support to existing wildlife in the project area. FWRC 19.165.020(3)(e) — The use of vegetation normally associated with streams, including primarily native riparian vegetation. The proposed vegetation enhancement of the riparian area will use native trees and shrubs including, but not limited to: bulrushes; sedges and rushes; red alder, black cottonwood; and big leaf maple, Douglas fir, and western hemlock. The planting of the above -referenced vegetation will occur in the following four zones, respectively: emergent bottom zone; riparian emergent zone; riparian forest/scrub-shrub zone; and upland riparian forest zone. FWRC 19.165.020(3)(1)— The creation of spawning and nesting areas, wherever appropriate. The applicant proposes the construction of habitat improvement stnichires including brush piles, snags, and bat boxes. The structures will provide cover from predators, assist thermal regulation, and provide nesting areas. Such enhancements are intended to increase stream riparian and wildlife functions. FWRC 19.165.020(3)(g) — The re-establishinent of the fish population, wherever feasible. Areas within the projected scope of work do not support fish populations. The existing fish blockage is downstream and outside the scope of this project. FWRC 19.165.020(3)(h) — The restoration of water flow characteristics compatible with fish habitat areas, wherever feasible. The restoration of water flow characteristics compatible with fish habitat areas is not feasible due to the following: lack of perennial headwater source; high proportions of impervious surfaces in the immediate area that result in flashy flow conditions during rainfall; and zero flow periods during the summer months. WSDOT Triangle Project Filc #09-104330-00-UP / poc ID 52650 Hearing Examiner Staff Report Page 5 of 17 FWRC 19.165.020(3)(i) — The tilling and re -vegetation of the prior channel. A majority of the filled channel will used for the new roadway section. The northern portion of the prior channel will be filled and planted with upland riparian forest vegetation as shown on the relocation site plan (Exhibit J). FWRC 19.165.020(3)6) — A proposed phasing plan specifying time of year for all project phases. As a contractor for the stream relocation work has not yet been determined, a phasing plan was not provided. As a condition of approval, staff recommends the applicant subrrrit a phasing plan upon selection of a contractor. Stream Relocation Decisional Criteria FWRC 19.165.020(4) — The city will allow a stream to be relocated only if water quality, habitat, and stormwater retention capability of the streams will be significantly improved by the relocation. Convenience to the applicant in order to facilitate general site design may not be considered. The stream relocation will improve water quality, habitat, and stor nwater retention capabilities via the following improvements: Water Quality — Below the Ordinary High Water Mark (OHWM), bulrush and bur -reed plugs will be planted. Above the OHWM in seasonally and occasionally inundated areas, slough sedge and various rush species will be planted. New plantings, the imported stream substrate, and coir matting erosion control features will improve the water quality of the tributary. • Habitat —Large woody debris, native plantings, brush piles, snags, and bat boxes placed within the relocation corridor will provide improved habitat for existing and new wildlife in the project area. ■ Stormwater Retention — Newly planted vegetation within the riparian corridor will provide improved opportunities for stormwater containment by capturing and storing rainfall in the canopy and releasing water into the atmosphere through evaporation. In addition, tree roots and leaf litter create soil conditions that promote the infiltration of rainwater into the soil. ■ Convenience to Site Design — Several alternatives were developed and analyzed during the design process. The proposed plan was selected for its top scores in minimizing environmental impacts. FWRC 19.165.020(6) — The amount of flow and velocity of the stream may not be increased or decreased as the stream enters or leaves the subject property. There are no sources of runoff entering or leaving Tributaiy 0016A within the realigned stream segment resulting in zero increase or decrease in flows or velocities as the stream enters or leaves the subject property. WSDOT Tiiaugle Project File 409-104380-00-IJP / Doc ID 52650 Hearing Examiner Staff Report Page 6 of 17 X. ANALYSIS OF CULVERT REQUEST AND DECISIONAL CRITERIA PURSUANT TO FWRC 19.165.040 The proposed road irrlprovements will require the applicant to extend three culverts for a total of 185-lineal feet and install one new culvert measuring 65-lineal feet. As shown on page 9 of the stream mitigation plan (Exhibit I) the culverting request includes: 1) One 50-foot extension will be placed beneath the new southbound off ramp from Interstate-5 to South 348`' Street; 2) One 50-foot extension will be placed beneath the new southbound onralnp to Interstate-5 from South 348'h Street; 3) One 85-foot extension will be placed beneath Interstate-5 south of the proposed South 356'h Street off ramp; and 4) One new 65-foot culvert will be placed beneath the proposed South 356'h Street off ramp. Findings & Conclusions The following analysis and decisional criteria is provided in accordance to the culvert sections of the city's CAO as codified in FWRC 19.165.040. FWRC 19.165.040(4) — The culvert must be designed and installed to allow passage of fish inhabiting or using the stream. The culvert must be large enough to accommodate a 100-year storm Although the city's critical areas inventory currently classifies the watercourse a Major Stream (fish -bearing) analysis provided by the applicant concludes the stretch within the construction zone would constitute a Minor Stream (non -fish bearing) due to natural permanent blockage. FWRC 19.05.130 defines a major stream as: any stream, and the tributaries to any steam, which contains or supports, or under normal circumstances contains or supports, resident or migratory fish. If there exists a natural permanent blockage on the steam course which precludes the upstream movement of anadromous salmonid fish, then that portion of the stream which is downstream of the natural permanent blockage shall be regulated as a major steam. Within the construction area, Tributary 0016A does contain a natural permanent blockage in the form of intermittent and flashy flows which do not support or tinder normal circumstances support resident or migratory fish. As detailed in the applicant's analysis (Exhibit K), fish are not capable of inhabiting the portion of the stream within the construction boundaries due to inadequate flows. Staff finds the stretch of watercourse within the construction zone would constitute a `minor stream' as defined by FWRC 19.05.130 due to natural permanent blockage; therefore, fish passable culverts are not required. One -Hundred Year Storm. — The estimated 100-year floor for the new culvert beneath South 3561h Street and Interstate 5 is 32 cfs. Based on the channel and culvert grade, the culvert extensions have the capacity to pass a maximum flow of 120 cfs and 130 cfs, respectively. z The 35-foot callout on page 23 Figure 6 is incorrect. The extension as concluded in the analysis on page 9 of the report states the extension is 85-feet. WSDOT Triangle Project File #09-104380-00-UP ' Doc ID 52650 Hearing Examiner Staff Report Page 7 of 17 FWRC 19.165.040(5) — The applicant shall, at all times, keep all culverts on the subject property free of debris and sediment so as to allow free passage of water and, if applicable, fish. The city shall require a bond under Chapter 19.25 FWRC to ensure maintenance of the culvert approved tinder this section. The WSDOT Maintenance and Operation Division -Maintenance Manual' requires inspection and cleaning a minimum of two times per year. Additional inspections tnay occur due to heavy precipitation and flooding. Pursuant to the Revised Code of Washington (RCW) 35.21.470, bonding of government agencies is not permitted. Staff finds the department's maintenance procedures adequate to provide continuous flow through the proposed culverts. Culvert Approval Criteria FWRC 19.165.040(3)(a) — The city will allow a stream to be put in a culvert only if no significant habitat area will be destroyed. No significant habitat areas will be destroyed as the culverts are within areas that are currently inhospitable to typical wildlife habitat as it is adjacent to major interstate and commercially zoned properties. The applicant proposes to provide native plantings in areas that will be impacted and provide off -site mitigation to a separate tributary to the Hylebos Creek. FWRC 19.165.040(3)(b) — The city will allow a stream to be put in a culvert only if it is necessary for some reasonable use of the subject property. Convenience to the applicant in order to facilitate general site design will not be considered The applicant must demonstrate, by submitting alternative site plans showing the stream in an open condition, that no other reasonable site design exists. Several alternatives were developed and analyzed during the design process. The proposed plan was selected for its top scores in minimizing environmental impacts. The new roadway sections require extensions to existing culverts and one new culvert. Staff did not find it necessary for the applicant to submit alternative plans as the existing roadway sections and the proposed expansions did not make it possible for the stream to flow in an open condition. XI. ANALYSIS OF STREAM BUFFER INTRUSION PURSUANT TO FWRC 19.165.070 Essential Public Facilities, Public Utilities and Other Public Improvements — The director of community development may permit the placement of an essential public facility, public utility, or other public improvements in a setback from a stream if he or she determines that the line or improvement must traverse the setback area because no feasible alternative location exists based on an analysis of technology and system efficiency. The specific location and extent of the intrusion into the setback area must constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. Findings & Conclusions The following analysis and decisional criteria is provided in accordance to the intrusion into setbacks with regard to essential public facilities section of the city's CAO as codified in FWRC 19.165.070. WSDOT Triangle Project File #09-104380-00-UP / Doe ID 52650 Hearing Exanuner Staff Repart Page 8 of 17 Due to roadway sections expansions and construction of new stormwater retention/water quality facilities, approximately 4.64 acres of stream buffer area will be permanently impacted. Construction activities associated with the proposed improvements will temporarily impact approximately 1.28 acres of buffer area. As mentioned previously, several alternatives were developed and analyzed during the design process. The proposed plan was selected for its top scores in minimizing environmental impacts. Staff finds the proposed roadway improvements minimize buffer impacts to the extent possible. While not required by FWRC, the applicant has proposed offsite mitigation on the Covington site that would provide buffer habitat to the North Fork of West Branch of Hylebos Creek. XII. ANALYSIS OF STRUCTURES, IMPROVEMENTS, AND LAND SURFACE MODIFICATIONS wnitm REGULATED WETLANDS PURSUANT TO FWRC 19.175.030 A proposed retaining wall and grading activities to support roadway expansion along State Route 18 will result in the loss of Wetland M and Wetland N (Exhibit H, Pages 19 & 20). Total improvements and surface modifications to the wetlands total 0.23 acres, which the applicant proposes to mitigate at a WSDOT owned 3.37 acre parcel (Corrington site) containing existing in -kind wetlands and the North Fork of Hylebos Creek. The applicant has chosen off -site mitigation opposed to onsite mitigation as it will provide a greater increase of wetland and wildlife habitat values for the overall Hylebos Creek watershed. Onsite mitigation is not a practical approach due to the adjacent high use of automobile traffic and resulting in limited potential for wildlife habitat_ Findings & Conclusions The following analysis and decisional criteria is provided in accordance to the structures, improvements, and land surface modifications within regulated wetlands section of the city's CAO as codified in FWRC 19.175.030. FWRC 19.175.030(5)(a), Mitigation Plan Elements i) Environmental Goals and Objectives The goal of the proposed mitigation is to ensure that no net loss of wetland functions and values occurs as a result of the proposed wetland and buffer impacts. The plan proposes to reach the goal by achieving these objectives: • Creation of 0.32 acres of new wetland. ■ Enhancement of 1.37 acres of existing emergent wetlatid. • Enhancement of 1.09 acres of wetland and riparian buffer. • Improve water quality, hydrologic, and habitat functions of wetlands by increasing flood storage capacity and adding additional vegetation classes. ii) Performance Standards Performance standards provide benchmarks for measuring achievement of the goals and objectives of the Corrington site within a specified period. Hydrologic — Years 1, 2, and 3 — The soils will be saturated to within six inches of the surface, or standing water will present within 12-inches of the surface for at least four consecutive weeks of the growing season in years when rainfall meets or exceeds the 30-year average. WSDOT Triangle Project File 1109-104380-00-UP / Doc ID 52650 Hearing Exanuner Staff Report Page 9 of 17 Year 10 — The Corrington wetland area will be delineated using current methods to assure that the mitigation site contains a minimum of 0.32 acres of created wetland Wetland and Buffer Vegetation — Years 1 and 3 — Native wetland woody species will achieve an average density of at least four plants per 100 square feet in scrub -shrub and forested communities. Year 3 — Aerial cover of native herbaceous species will be at least 30 percent in emergent areas. Year 5 — Aerial cover of native scrub -shrub and forested communities will be at least 35 percent. Year 7 — Aerial cover of scrub -shrub and forested communities will be at least 50 percent. Years 1, 3, 5, and 7 — Class -A noxious weeds and invasive species will not exceed 25 percent of aerial cover. Year 10 — Aerial cover of native scrub -shrub and forested communities will be at least 60 percent. Wildlife Structures — Year 1 — Ensure the following structures have been planted within the wetland and buffer areas and meet the specific size requirements within the mitigation plan. • Ten large woody debris items • Four snags • Five habitat brush piles iii) Detailed Construction Plans The following plans (Exhibit M) prepared by Berger/Abamprovide a comprehensive overview of construction activity: • General notes & legend Site prep, Temporary Erosions and Sedimentation Control (TESC), and staging • Grading • Cross sections • Planting, details, and data sheet iv) Timing Following installation of erosion control items, grading of the offsite mitigation site will begin during the spring/summer'and will last approximately three weeks. The site will be prepared and soil remediated in the northern portion of the property after grading has been completed. The installation of the proposed wildlife habitat enhancement features will follow grading. wSDOT Triangle Project File N09-104330-00-UP / Doc ID 52650 Hearing Examiner Staff Report Page 10 of 17 All bare ground will be covered with a four -inch layer of mulch and hydroseed. Woody vegetation and aquatic plugs will be planted between December P' and March 3 1 " v) Monitoring Program for a Minimuum. of Five Years WSDOT has proposed a monitoring program of the Corrington site for 10-years following installation of the mitigation iterms. If performance standards are achieved in less than 10 years, WSDOT will terminate the monitoring. The city's Critical Areas Ordinance does require a minimum of five years of monitoring with no option of early termination. Monitoring will be designed to determine if the performance measure/standards have been met. Quantitative and qualitative monitoring will be completed and documented in the t"`, 2", 31'17 5"% 7"' and 10'h years following mitigation construction. Monitoring reports will be submitted to the city for review and comment. vi) Contingency Plan Hydrology — Contingency measures will be implemented based on observed conditions or monitoring data. Steps to address insufficient or excessive hydrology are: • Clearly identify the source of the problem. • Consult with the mitigation design team to determine an appropriate course of action. • Adjust elevation or install water management structures to achieve appropriate hydrologic conditions. Vegetation — Contingencies for plant mortality and poor plant cover include: • Plant replacement • Weed control • Herbivore control • Fence installation and sensitive area signage Wildlife Structures — Replace or repair mussing or damaged structures. FWRC 19.175.030(5)(b), Mitigation Applicants are permitted to choose creation, restoration, or enhancement as a means to adequately mitigate permanent impacts to regulated wetlands. To mitigate the permanent impacts to the 0.03 acre Category II Wetland M and 0.20 Category III WetlandN, the applicant proposes offsite compensatory mitigation that includes creation and enhancement. Project site mitigation was not chosen as the Corrington site would provide a higher functioning wetland and habitat value to the drainage basin than providing mitigation adjacent to roadways. The Corrington mitigation site contains a Category I wetland and is within the same drainage basin (Hylebos Creek) as the two wetlands that will be permanently impacted. The site was chosen for its high potential for success and relatively low development that Surround the area. As shown in the tables below, and presented in the mitigation plan (Exhibit H), the proposed mitigation will result in no net loss of wetland area and exceeds in -kind requirements. Minimum acreage mitigation ratios pursuant to FWRC 19.175.030(5)(c) are satisfied. WSDOT Triangle Project File #09-104330-00-UP / Doc ID 52650 Hearing Examiner Staff Report Page 11 of 17 FWRC 19.175.030(5)(c), Minimann Acreage Mitigation Ratio Minim.unz Mitigation — The following mitigation ratios apply to each of the following permanently affected wetlands. Wetland Creation/ Enhancement Required Acreage of Rating/Size Restoration In -Kind Mitigation Wetland M 0.06 creation/restoration; or 0.12 Category II 2 1 4:1 enhancement 0.03 acres Wetland N 0.30 creation/restoration; or 0.60 Category 111 1.5.1 3:1 enhancement 0.20 acres Total 0.36 creation/restoration; or 0.72 0.23 acres enhancement Proposed Mitigation — The applicant proposes to nutigate each affected wetland on the Corrington site using a combination of creation and enhancement. While the creation ration is short 0.04 acres of the minimum, the enhancement component exceeds the 0.72 uvnimunl Staff finds the ratios provide adequate mitigation as it provides a near 7:1 acre ratio of mitigation and no net loss of wetlands within the Hylebos Creek basin. Wetland Creation Enhancement Total Acreage of Rating In -kind Mitigation Corrington Site 0.32 acres 1.37 acres 1.69 acres Category I FWRC 19.175.030(5)(d), Tinting The applicant proposes off -site mitigation work to begin concurrently with construction of the Triangle Project. State law prohibits the city to require WSDOT to provide a performance and maintenance bond for the mitigation construction. FWRC 19.175.030(5)(e), Inspections As a code based condition, the applicant will be required to submit monitoring reports, conducted by a professional approved by the city, for a minimum of five years following completion of the mitigation project. Wetland Mitigation Approval Criteria a) It will not adversely affect water quality. The off -site mitigation site will not adversely affect water quality as it will create an additional Category 1 wetland and enhance the existing wetland buffer. Such improvements provide a natural detention and filtration process that prevent pollutants from traveling downstream. Therefore, the proposed wetland mitigation will not adversely affect water quality. b) It will not adversely affect the existing quality of the wetland's or buffer's wildlife habitat. The mitigation plan will have habitat features that include large woody debris, snags, and wildlife habitat brush piles. Habitat features and native wetland vegetation WSDOT Triangle Project File 909-104380-00-1]P / Doe ID 52650 Hearing Examiner Staff Report Page 12 of 17 plating will provide a significant improvernent to the existing site conditions as it has lost plant diversity due to invasive species becoming established on most of the property. Therefore, the proposed wetland mitigation will not adversely affect the existing quality of wetland or buffer wildlife habitat. c) It will not adversely affect drainage or stormwater retention capabilities. The net increase in wetlands, coupled with the enhancement of existing wetlands, will provide a larger more improved functioning area to store and treat stormwater before it is naturally released downstream. Therefore, the proposed wetland mitigation will not adversely affect drainage or stormwater retention capabilities. d) It will not lead to unstable earth conditions nor create erosion hazards. Typical erosion and sedimentation practices such as silt fencing, covering exposed soils, and berms will provide adequate erosion control. Grading activities will take place during the summer construction window. Proposed contours and native vegetative planting will provide erosion control and stabilization following construction. Therefore, the proposed wetland mitigation will not lead to unstable earth conditions or create erosion hazards. e) 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. Much of the surrounding area is designated open space and lower density residential owned by the city or state. Wetland and riparian enhancement activities on the Corrington site will improve the Hylebos Creek watershed by increasing habitat and hydrological functions. Therefore, the proposed wetland mitigation will not be materially detrimental to any other property in the area, the city as a whole, or result in the loss of open space. f) It will result in no net loss of wetland area, function, or value. Off site wetland mitigation will provide approximately 7:1 ratio of in -kind mitigation via creation and enhancement. Although 0.23 acres of wetlands will be permanently impacted, 0.32 acres of wetland will be created and 1.37 acres will be enhanced. Functions and values of the mitigated area include flood flow attenuation; sediment removal; toxicant and nutrient uptake; habitat for amphibians and aquatic invertebrates; and general fish habitat. Therefore, the improvements will result in no net loss of wetland area, function or value. g) The project is in the best interest of the public health, safety, or welfare. The Triangle Project will improve safety, relieve congestion, and improve mobility for the citizens of Federal Way. The proposed instigation will result increased habitat and hydrological functions that will ultimately improve the Hylebos Creek watershed. Therefore, the proposal is in the best interest of the public health, safety, or welfare. h) The applicant has demonstrated sufficient scientific expertise and supervisory capability to carry out the project. The applicant has provided a wetland mitigation plan prepared by wetland scientists contracted by Berger/ABAM with consultation provided by the .Army Corp of Engineers. The site will be monitored for a minimum of five years with status updates provided to the city, Washington State Department of Ecology, and Army Corp of Engineers. Therefore, the applicant has demonstrated sufficient scientific expertise and supervisory capability to carry out the project. WSDOT Triangle Project Pile N09-104380-00-UP / Doc ID 52650 Hearing Examiner Staff Report Page 13 of 17 i) The applicant is committed to monitoring the project and to making corrections if the project Jails to meet the projected goals. The city's Critical Areas Ordinance requires a five year monitoring plan, which the applicant has extended to ten -years. Contingency plans have been provided for failures associated with hydrology, vegetation, and wildlife structures. Therefore, the city finds the applicant is committed to monitoring the project and to making corrections if the project fails to meet projected goals. X1II. ANALYSIS OF STRUCTURES, IMPROVEMENTS, AND LAND SURFACE MODIFICATIONS WITHIN WETLAND SUFFERS PURSUANT TO FWRC 19.175.040 Essential Public Facilities, Public Utilities, and Other Public Improvements — The director of community development may permit the placement of an essential public facility, public utility, or other public improvements in a regulated wetland buffer if he or she determines that the line or improvement must traverse the buffer because no feasible or alternative location exists, based on an analysis of technology and system efficiency. The specific location and extent of the intrusion into the buffer must constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. Findings & Conclusions The following analysis and decisional criteria is provided in accordance to the structures, improvements and land surface modifications within regulated wetland buffers with regard to essential public facilities section of the city's CAO as codified in FWRC 19.175.0400. Temporary Encroachments — Construction activities associated with the proposed road improvements will require temporary wetland buffer intrusions totaling 0.60 acres. As shown in the wetland mitigation plan (Exhibit H, Pages 22-25), the temporarily affected wetland buffers are M, K, P, U, and AB. The applicant proposes to mitigate the temporary construction impacts by re -vegetation via hydro -seeding or native shrub/tree plantings where appropriate. Permanent Encroachments — Wetland buffer intrusions to accommodate new structures and improvements total 1.05 acres. As shown in the wetland mitigation plan sheets (Exhibit H, Pages 22-25), the permanently affected wetland buffers are M, P, U, and AB. 1 Wetland M — Permanent impacts to wetland buffer M, totaling 0.56 acres, are required due to grade/fill, expansion of the roadway. and the installation of a retaining wall. 2. Wetland P — Permanent impacts to wetland buffer P, totaling 0.12 acres, are required due to grade/fill and expansion of the roadway. 3. Wetland U — Permanent impacts to wetland buffer U, totaling 0.14 acres, are required due to grade/fill activities associated with roadway replacement. 4. Wetland AB — Permanent impacts to buffer AB, totaling 0.23 acres, are required due to grade/fill activities, stormwater facility inlproveznents, retaining wall, and expansion of the roadway. The applicant proposes approximately 1.03 acres of wetland buffer enhancement at the Carrington compensatory site to offset permanent buffer impacts within the project area. Enhancements WSDOT Triangle Project File N09-104380-00-UP / Doc ID 52650 Hearing Examiner Staff Report Page 14 of 17 include native plantings, large woody debris, and habitat brush piles. Such mitigation is not a requirement for wetland buffer encroachments associated with essential public facilities. In order to avoid and minimize buffer impacts, the applicant chose the current design from 11 total alternatives. The current option was chosen, in part, due to its minimized impact to the environment. Total avoidance of the wetland buffer was not possible due to existing roadway segments and constraints associated with safety and design guidelines. Staff finds the proposal constitutes the minimum necessary encroachment. )UV.

Hearing. aring. The Hearing Examiner conducted a hearing on the application at 2:00 p.m. at Federal Way City Hall on April 7, 2010. Substantive: 3. Sit —Proposal Description. The applicant is requesting clearing and grading activities, wetland mitigation, permanent and temporary wetland buffer intrusion, and stream culvertinglrelocation associated with the replacement of the I5 and SR 18 cloverleaf interchange ramps and new direct connection from westbound SR 18 to SR 161 in the vicinity of South 359"' Street. The subject area is within the WSDOT right-of-way for the 15 corridor between South 336`h Street and SR 161, WSDOT right-of-way within SR 18 between Weyerhaeuser Way and the 15 cloverleaf, two commercially zoned parcels owned by WSDOT, and three private parcels abutting the WSDOT right-of-way. 4. Characteristics of the Area. The areas surrounding the project site include multi -family, commercial enterprise, and corporate park zoning designations. Current uses include retail, offices, church, vacant private land, and vacant parcels owned by the WSDOT. 5. Adverse Impacts. The project has undergone a SEPA review and was issued a DNS, on May 11, 2007. Staff did not receive any written comments regarding the SEPA determination. Staff finds that the analysis provided from the 2007 DNS is valid for the current proposal. Due to the need for filling, stream relocation, intrusion of setbacks, intrusion of buffers, and intrusion of wetlands, there will be significant impacts to the property. However as detailed in the environmental impact statement and mitigation plans provided with the application, these impacts will be sufficiently mitigated to prevent adverse impacts as a result of the project. The project will also include off -site compensatory mitigation to include wetland creation, wetland enhancement, wetland buffer enhancement, and the creation and enhancement of stream habitats. The staff in their analysis of the project identified no significant adverse impacts. In addition, no comments were received on this application. Finally, approval is conditioned upon compliance with certain applicable critical areas and development regulations adopted by the City, which should further ensure that adverse impacts are minimized. 6. Other Findings. Staff's proposed findings of fact set forth in the March 31, 2010, staff report prepared by Mr. Herrera for this project are adopted herein by this reference to the extent that they are not inconsistent or in conflict with any finding or conclusion set forth in this decision. CONCLUSIONS OF LAW Procedural: i. Authority of Hearing Examiner: FWCC Chapter 22 Article VII provides the Examiner with the authority to conduct a hearing and issue a decision on Process IV Reviews, of which applicant's requested activities for stream relocation, culvert, intrusion into stream setback, (BIT784663. DOC; I \ 13041,15003411 WSDOT — Triangle Project p. 2 Findings, Conclusions and Decision improvements within regulated wetland, and improvements within regulated wetland buffer are subjece. Substantive: 2, Zoninz Designation: The WSDOT right-of-way is zoned Commercial Enterprise, while the compensatory mitigation site is located within a single-family medium density residential RS35.0 zoning district. 3. Review Criteria and Application. Applicable criteria for the requested stream relocation, culvert, intrusion into stream setback, improvements within regulated wetland, and improvements within regulated wetland buffer applications are found in Title 19 FWRC. Those criteria are quoted in italics below and applied to the application under corresponding Conclusions of Law. Stream Relocation: Federal Way Revised Code, Stream Relocation Decisional Criteria, 19.165.020(3): As part of any request under this section, the applicant must submit a stream relocation plan, prepared by a qualified professional approved by the city, that shows the following: (a) The creation of a natural meander pattern. (b) The formation of gentle side slopes, at least two feet horizontally to one foot vertically, and the installation of erosion control features for stream side slopes. (e) The creation of a narrow subehannel, where feasible, against the south or west bank. (d) The utilization of natural materials, wherever possible. (e) The use of vegetation normally associated with streams, including primarily native riparian vegetation. 69 The creation of spawning and nesting areas, wherever appropriate. (g) The re-establishment of the fish population, wherever feasible. (h) The restoration of water flow characteristics compatible with fish habitat areas, wherever feasible. (i) The filling and revegetation of the prior channel. (j) A proposed phasing plan specking time of year for all project phases. 4. As demonstrated in the analysis contained in the Staff Report for the above criteria, which is incorporated herein by this reference, the applicant has furnished an appropriate stream relocation plan that meets the requirements of FWRC 19.165.020, except for submitting a proposed phasing plan, which will be imposed as a condition of approval. Federal Way Revised Code, Stream Relocation Decisional Criteria, 19.165.020(4): 2 Pursuant to FWRC 19.70.010, if the development, use or activity that requires approval through process II or III is part of a proposal that also requires approval through process IV, the entire proposal will be decided upon using process IV, if it will result in more efficient decision making. (BFP784663.DOC;1\13041.150034\ ) WSDOT —Triangle Project p. 3 Findings, Conclusions and Decision The city will allow a stream to be relocated only if water quality, habitat and stormwater retention capability of the streams will be significantly improved by the relocation. Convenience to the applicant in order to facilitate general site design may not be considered. 5. In order to improve water quality, the project includes new vegetation plantings below the ordinary high water mark (OHWM), as well as more restrictive plantings in seasonally and occasionally inundated areas above the OHWM. These new plantings, as well as imported stream substrate and coir matting erosion control features will improve water quality of the tributary. Habitats will be improved by incorporating large woody debris, native plantings, brush piles, snags, and bat boxes placed within the relocation corridor; which will all provide improved habitat for existing and new wildlife in the area. Stormwater retention will be improved by newly planted vegetation within the riparian corridor to improve opportunities for stormwater containment by capturing and storing rainfall in the canopy and releasing water into the atmosphere through evaporation.. In addition, tree roots and leaf litter will create soil conditions that promote the infiltration of rainwater into the soil. In regards to site convenience, several alternatives were developed and analyzed during the design process, but the proposed plan was selected for its ability to minimize environmental impacts. As such, the project will significantly improve the water quality, habitat, and stormwater retention capabilities of the stream due to relocation. Federal Way Revised Code, Stream Relocation Decisional Criteria, 19.165.020(5): Prior to diverting water into the new channel, a qualified professional approved by the city shall inspect the new channel following its completion and issue a written report to the director of community development stating that the, channel complies with the requirements of this section. 6. This has been made a condition of approval. Federal Way Revised Code, Stream Relocation Decisional Criteria, 19.165.020(6): The amount offlow and velocity of the stream may not be increased or decreased as the stream enters or leaves the subject property. 7. There are no sources of runoff entering or leaving Tributary 0016A within the realigned stream segment resulting in zero increase or decrease in flows or velocity as the stream enters or leaves the subject property. Culverts: Federal Way Revised Code, Culvert Decisional Criteria, 19.165.040(3): The city will allow a stream to be put in a culvert only if: (a) No signf cant habitat area will be destroyed; and (b) It is necessary for some reasonable use of the ,subject property. Convenience to the applicant in order to facilitate general site design will not be considered. The applicant must demonstrate, by submitting alternative site plans showing the stream in an open condition, that no other reasonable site design exists. (BFI,784663.DOC,1\1 3041 . 1 50034\ ) WSDOT — Triangle Project p. 4 Findings, Conclusions and Decision 8. As discussed in conjunction above with adverse impacts and habitat improvements, no significant habitat area will be destroyed. The culverts are within areas that are currently inhospitable to typical wildlife habitat as it is adjacent to major interstate and commercially zoned properties. However, the applicant will be providing native plantings in the area, and will also be providing separate off -site mitigation. Additionally, the applicant analyzed several alternative plans prior to and during the design process. Staff did not require that these plans be submitted, as existing roadway sections and the proposed expansions did not make it possible for the stream to flow in an open condition. As such, the above criteria are met. Federal Way Revised Code, Culvert Decisional Criteria, 19.165.040(4): The culvert must be designed and installed to allow passage offish inhabiting or using the stream. The culvert must be large enough to accommodate a 100 year storm. 9. As detailed in the staff report, and in Exhibit K, although the City currently classifies the watercourse as a Major Stream (fish -bearing) analysis provided by the applicant concludes that the portion within the project site would actually constitute a Minor Stream (non -fish bearing) due to a natural permanent blockage. The City testified during the hearing that it intends to change the classification based on this new evidence. The blockage is in the form of intermittent and flashy flows that do not support, or under normal circumstances support, resident or migratory fish. Additionally, fish are not capable of inhabiting the subject portion of the stream within the project boundaries due to inadequate flows. As such, there are no fish inhabiting or using the stream around which to design and install the culvert. In regards to the 100-year storm, based on channel and culvert grade, the culvert extensions have the capacity to pass a maximum flow of 120 cfs and 130 cfs, compared to the current 32 cfs necessary for the 100-year plan. Federal Way Revised Code, Culvert Decisional Criteria, 19.165.040(5): The applicant shall, at all times, keep all culverts on the subject property free of debris and sediment so as to allow free passage of water and, if applicable, fish. The city shall require a bond under Chapter 19.25 FWRC to ensure maintenance of the culvert approved under this section. 10. The WSDOT Maintenance and Operation Division "Maintenance Manual" requires inspection and cleaning of culverts a minimum of two times per year, with allowance for additional inspections due to heavy precipitation and flooding. As such, the department's maintenance procedures are adequate to provide guarantees of continuous flow through the proposed culvert. A bond will not be required because RCW 35.21.470 is directly on point prohibiting the City from imposing such a requirement as a condition of approval on state agencies. Iiarusion unto Stream Setback: Federal Way Revised Code, Stream Buffer Intrusion Decisional Criteria,19.165.070(i): Essential public facilities, public utilities and other public improvements.

The specific location and extent of the intrusion into the setback area must constitute the minimum necessary encroachment to meet the requirements of the public, facility or utility. "Public utility and other public improvements " shall not include improvements whose primary purpose is to benefit a private development, including without limitation interior roads or privately owned detention facilities installed within or during the construction of a residential subdivision, binding site plan, or other commercial development. 11. As discussed previously, several alternatives were developed and analyzed during the design process, prior to settling on the current proposal. The plan was selected for its minimization of environmental impacts. The proposed roadway improvements minimize buffer impacts to the extent possible due to the nature of this proposal. Additionally, although not required, the applicant has proposed off -site mitigation that would provide buffer habitat to the North Fork of West Branch Hylebos Creek. Improvements within Regulated Wettand: Federal Way Revised Code, Structures, improvements and Iand surface modification within regulated wetland buffers Decisional Criteria, 19.175.030(4)(a): It will not adversely affect water quality, 12. The off -site mitigation site will not adversely affect water quality, as it will create an additional Category l wetland and enhance the existing wetland buffer. As such, water quality should not be adversely affected. Federal Way Revised Code, Structures, improvements and land surface modification within regulated wetland buffers Decisional Criteria, 19.175.030(4)(b): It will not adversely affect the existing quality of the wetland's or buffer's wildlife habitat. 13. The proposal includes introduction of large woody debris, snags, native vegetation planting, and wildlife habitat brush piles in order to improve the existing site conditions as the site has lost plant diversity due to establishment of invasive species on most of the property. As such, the proposal will not adversely affect the existing quality of the wetland, and will actually improve the quality. Federal Way Revised Code, Structures, improvements and land surface modification within regulated wetland buffers Decisional Criteria, 19.175.030(4)(e): It will not adversely affect drainage or stormwater retention capabilities. 14. The net increase in wetlands, in addition to the enhancement of existing wetlands will provide a larger and higher functioning area to store and treat stormwater before being naturally released downstream. As such, the proposal will not adversely affect drainage or stormwater IBI-P784663.DOC;1\13041.150034\ } WSDOT — Triangle Project p. 6 Findings, Conclusions and Decision retention capabilities, and will actually improve those aspects. Federal Way Revised Code, Structures, improvements and land surface modification within regulated wetland buffers Decisional Criteria, 19.175.030(4)(d): It will not lead to unstable earth conditions nor create erosion hazards. 15. Typical erosion and sedimentation practices will provide adequate erosion control on site. Additionally, grading activities will take place during the summer months in order to avoid erosion. As such, the proposal will not lead to unstable earth conditions or create erosion hazards. Federal Way Revised Code, Structures, improvements and land surface modification within regulated wetland buffers Decisional Criteria, 19.175.030(4)(e): 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. 16. Much of the surrounding area is designated open space and low density residential owned by either the City or State. Enhancement activities on the site will improve the Hylebos Creek watershed by increasing habitat and hydrological functions. As such, the project will not be detrimental to any other property in the area, and is likely to improve the quality of the surrounding property. Federal Way Revised Code, Structures, improvements and land surface modification within regulated wetland buffers Decisional Criteria, 19.175.030(4)(f): It will result in no net loss of wetland area, function or value. 17. Although .23 acres of wetlands will be permanently impacted, .32 acres of wetland will be created, and 1.37 acres will be enhanced. Additionally, improved functions and values of the areas include flood flow attenuation, sediment removal, toxicant and nutrient uptake, habitat for amphibians and other aquatic invertebrates, and general fish habitats. As such, the project will not result in a net loss of wetland area, function, or value. Federal Way Revised Code, Structures, improvements and land surface modification within regulated wetland buffers Decisional Criteria, 19.175.030(4)(g): The project is in the best interest of the public health, safety or welfare. 18. The project will improve safety, relieve congestion, and improve mobility for the citizens of Federal Way. Additionally, the proposed mitigation will result in increased habitat and hydrological functions that will ultimately improve the Hylebos Creek watershed. As such, the proposal is in the best interest of the public health, safety, and welfare.

(ii) Projected losses injunction or value. (iii) Findings of special studies coordinated with agencies with expertise which demonstrate that no net loss of wetland function or value is attained under an alternative ratio_ (iv) In no case shall the minimum acreage replacement ratio be less than 1.25:1. (d) Timing. All required wetland mitigation improvements, including monitoring, shall be completed and accepted by the director of community development prior to beginning activities that will disturb regulated wetlands, or the applicant shall provide the performance and maintenance bond specified in subsection (5)(a)(vii) of this section. In either event, the applicant may not take any action that disturbs a regulated wetland or its buffer until the director has reviewed and approved the mitigation plan. All wetland- or buffer -disturbing activities, and all mitigation, shall be timed to reduce impacts to existingplants and animals. (e) Inspections. The applicant shall pay for services of a qualified professional selected and retained by the city to review the wetland mitigation report and other relevant information, conduct periodic inspections, issue a written report to the director of community development stating that the project complies with requirements of the mitigation plan, and to conduct and report to the director on the status of the monitoring program, 21. As discussed in depth and demonstrated in the analysis contained in the Staff Report for the above criteria, which is incorporated herein by this reference, as conditioned, the applicant (EiF1)784663.DOC;1113041.1500341 i WSDOT —Triangle Project P. 9 Findings, Conclusions and Decision will meet the requirements of FWRC 19.175.030(5). Because offsite compensatory mitigation at the proposed Covington site, which includes creation and enhancement of wetlands, will trigger requirements of FWRC 19.120.020(2), condition of approval #5 set forth in the staff report, as further clarified in Exhibit Q, will be imposed. In Exhibit P, the applicant cites to general authority and powers granted to WSDOT concerning state highways for the proposition that it is exempt from such conditions. (As the party claiming the exemption, it is incumbent upon WSDOT to demonstrate that it qualifies. RCW 47.01.260 and .031 are not, however, exemptions that are directly on point to this condition.) To grant an exemption, the Examiner needs authority directly on point (like RCW 35.21.470, which notwithstanding the City's code requirement for bonds, prohibits its application on state agencies). None was provided. It may have been the intent of the state legislature to exempt WSDOT from requirements as those imposed by condition of approval #5 when it granted the general authority and powers cited by the applicant, but such intent is not clear on the face of the aforementioned statutes. In an administrative proceeding, the Examiner lacks jurisdiction to make determinations of state legislative intent from ambiguous statutes. Again, without an exemption on point, it is the Examiner's role in an administrative proceeding such as this to consider and impose all applicable codes as they are adopted by the Iocal jurisdiction. Finally, RCW 36.70A.103 directs state agencies to comply with local development regulations, and because FWRC 19.120.020(2) is an applicable local development regulation, WSDOT must comply with it. linproveirments within Regulated W'et,Iand Buffer.; Federal Way Revised Code, Structures, improvements and land surface modification within regulated wetland buffers Decisional Criteria, 19.175.040(3): Essential public facilities,' public utilities and other public improvements. The director of community development may permit the placement of an essential public facility, public utility or other public improvements in a regulated wetland buffer if he or she determines that the line or improvement must traverse the buffer because no feasible or alternative location exists based on an analysis of technology and system efficiency. The specific location and extent of the intrusion into the buffer must constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. 22. As discussed above, the location of the proposed project is vitally necessary and cannot be relocated. In order to avoid and minimize buffer impacts, the applicant chose the current design from 11 total alternatives. The current option was chosen in part due to its minimized impact to the environment. Total avoidance of wetland buffers was not possible however, due to the existing roadway segments and constraints associated with safety as well as design guidelines. As such, the proposal constitutes the minimum necessary buffer encroachment possible in association with this project. Federal Way Revised Code, Hearing Examiner Review Process IV Decisional Criteria, 19.70.150(3)(a): It is consistent with the comprehensive plan. (13FP784663.DOC;1\13041.150034\ ) WSDOT—Triangle Project p. 10 Findings, Conclusions and Decision 23. In addition to being generally consistent with Comprehensive Plan elements NEP4, NEG5, NEP37, NEP39, NEG7, NEP43, NEP44, NEP49, TG2, TG9, and TPI1, the project is specifically included in the City's highest priority project on I5 on FWCP page III-38.

The instant project has been reviewed under SEPA, the FWCP, all applicable provisions of FWRC Chapter 19, and all other applicable provision, and is consistent with all of these provisions. The applicant has also submitted a Joint Aquatic Resources Permit Application form. As such, this criterion has been met. Federal Way Revised Code, Hearing Examiner Review Process IV Decisional Criteria, 19.70.150(3)(c): It is consistent with the public health, safety, and welfare. 25. The project will improve safety, relieve congestion, and improve mobility for the citizens of Federal Way. Offsite mitigation will provide additional wetlands and improved function and value to the Hylebos Creek drainage basin. As such, this criterion has been met. Federal Way Revised Code, Hearing Examiner Review Process IV Decisional Criteria, 19.70.150(3)(d): The streets and utilities in the area of the subject property are adequate to serve the anticipated demand from the proposal. 26. The project will alleviate congestion and safety problems currently associated with SR 161, SR 18, and the I5 corridor. As such, the streets are not currently adequate to serve demand, and the project will alleviate that, thus meeting this criteria. Federal Way Revised Code, Hearing Examiner Review Process IV Decisional Criteria, 19.70.150(3)(e): The proposed access to the subject property is at the optimal location and configuration for access. 27. This element is not applicable, as the project is an improvement to existing State and interstate roadways. Federal Way Revised Code, Hearing Examiner Review Process IV Decisional Criteria, 19.70.150(3)(f): Traffc safety impacts ,for all modes of transportation, both on and off site, are adequately mitigated. {131'P784663.DOC;I\13041.150034\ } WSDOT —Triangle Project P. 11 Findings, Conclusions and Decision 28.
