The workshop started June 12`h, 2000 with a VE Team site visit and introduction to the Project, and ended June 15th, 2000 with a presentation of VE Recommendations. The conceptual baseline information available to the VE Team is listed in Section 3.4 (Baseline Materials) of this report. The Design Estimate Budget ' for construction costs is $15,609,000. The project completion is planned for Fall of 2001. DESCRIPTION OF STUDY The VE Workshop commenced with a site visit, and the Design Team and the City of Tukwila introducing the project to the VE Team. The Workshop ended when the VE Team presented its Recommendations to the Design Team,Transportation Improvement Board and the City of Tukwila. ' The workshop followed the six-phase VE Team Study Job Plan, including the Information,Function, Speculation, Evaluation,Development,and Presentation phases. ' The Value Improvement Matrix, found in Section 1, summarizes all study items. The VE team reviewed 47 specific items to arrive at the Value Improvement Recommendations that, if implemented,will result in: $1,819,000 Cost Savings $493,000 Added Costs Section 2 includes workbooks with comments and recommendations stemming from the application of creative ' ideas to improve the current design concept. Several recommendations highlight areas of opportunity for improving the value or function of the facility, cost avoidance, and/or life cycle cost savings, but have not been quantified due to limitations of the time and/or cost information. Section 3 of this report includes the VE study support documentation.

BASELINE INFORMATION Design Assumptions ' The design shows secant pile walls consisting of a row of 4-foot diameter drilled shafts, alternating between the primary and secondary pile,working in conjunction as a single wall. ' Reason for Selection Slurry walls could be considered in lieu of secant pile walls. Slurry walls are typically more cost effective than secant pile walls when the depth of the wall is greater than about 30 feet. In addition, the length of a slurry wall panel is typically 15 to 20 feet where a joint is located. The secant pile wall will have a joint every four feet. As a result, the leakage potential of the secant pile wall is much greater as there are about ' four times as many joints for secant pile walls as there are for slurry walls. Depending upon the required appearance of the wall, the slurry wall could also eliminate the need for the pre-cast fascia panels. Some architectural treatment would most likely be required,however. ' It should be noted that there are many more drilled shaft than slurry wall contractors in the Puget Sound area. Presently it is our understanding that there are no or a minimum of slurry wall contractors. However, that may change with the future Sound Transit construction. Slurry walls cost on the order of $40 to $50/SF of wall. Based on the $45/SF used for the secant pile wall in the cost estimate, there may not be a significant cost savings by using slurry walls. B. OPTIONS CONSIDERED Creative Idea List—Slurry in lieu of Secant Walls [Cl#2] ' C. ANALYSIS Advantages ' • Reduced leakage potential • Eliminates need for pre-cast fascia panels Disadvantages • Non-availability of slurry wall contractors and therefore,less competitive bids D. DEVELOPMENT/JUSTIFICATION Initial Cost Analysis tThere is no significant cost difference between the two methods. However, the design team may desire having the slurry wall bid as an alternative. E.

BASELINE INFORMATION ' Design Assumptions It may be feasible to use a temporary excavation support system such as soil mixing (3-auger mixing) or sheet pile walls in lieu of the proposed secant pile walls. There are several different construction ' techniques that use soil-mixing methods. B. OPTIONS CONSIDERED Creative Idea List— Alternate 3-pile Wall System(soil mixing) [Cl#8] Sheet Pile/Conventional Construction Boat Section [Cl#19] C. ANALYSIS Proposed Alternative A system developed by SMW Setko involves the use of three continuous flight augers that are rotated into the soil. As they are rotated, cement grout is injected into and mixed with the soil to form soil cement. The augers are withdrawn and steel wide flange sections are inserted into the wet soil cement. Typically, this system is used for temporary excavation support, not permanent installations, as the soil cement is susceptible to freeze-thaw and weathering. Tie-backs and/or internal bracing would most likely be required to support both the soil cement and steel sheet pile walls. Upon completion of the excavation, tremie seal construction and dewatering followed by constructing a ' conventional boat section could be accomplished for the roadway. The temporary excavation support system could be structurally incorporated into the permanent concrete walls of the roadway section if appropriate. ' Advantages • More cost effective ' Disadvantages • Potential vibrations due to the sheet pile installations • Temporary easements for tie-backs are required • Tie-back installation will be difficult considering the high groundwater table, poor soil conditions, and construction inefficiencies created by internal bracing 0 Separate foundation system would be required for the railroad bridges instead of the temporary excavation support system D.

BASELINE INFORMATION Design Assumptions The baseline design calls for an 81' section with an 18' clearance to the RR bridges, which includes 61/2' ' sidewalks, 4' bike lanes, and a 12' center column section, all at the roadway grade. Secant pile walls are constructed from the surface to a maximum depth of about 80' (see sketch of Current Design). Reason for Selection Cost reduction. ' Sketch of Current Design See attached. B. OPTIONS CONSIDERED ' Creative Idea List—Reduce Road (North &South)Wall Height [Cl#44] C. ANALYSIS Proposed Alternative ' An alternative to the baseline design would be to elevate the ped/bike sections (see also WkBk 2.5.1 for earthwork analysis). By removing these sections from the traveled lanes, a combined ped/bike corridor could be designed 9' below the bridge crossings and 9' above the roadway (splitting the difference in ' clearance). The secant pile walls could be placed at a varying grade up to 9' below the surface (see sketch of VE Recommendation). ' Advantages • Retaining walls and abutments are the single most expensive item in the Preliminary Cost Estimate for this project. Therefore,this recommendation will save construction cost and time. • The secant walls necessary for earthwork would be reduced in height up to 9' (to the grade of the ped/bike corridor), with the exception of secant wall supports for the RR bridge sections. The interurban trail pedestrian bridge is assumed to be supported independent of the secant walls. ' Disadvantages • An additional retaining wall section would be needed for the ped/bike corridor (although of a lesser strength and a more cost-effective method could be considered). The support system under the RR bridge sections and shoofly may also need additional footings.

WALLS AND ABUTMENTS ' 2.1.3—Reduce Road(North &South)Wall Height Initial Cost Analysis ' Depending on the design, the ped/bike corridor may return to grade before the roadway (approximated to 350' before the work limits). Assuming a $45/SF cost for the secant pile walls, work limits extending 1,250', and full secant sections to support the 20' UP and 40' BNSF bridge structures,the potential savings on secant wall construction is estimated to be about$225,000. Assuming a $20/SF cost for a masonry retaining wall, additional construction supporting the ped/bike corridor might incur a cost of about $100,000. Fascia and waterproofing costs are assumed to be the same as the baseline design. ' The potential initial savings to retaining walls and abutments would be about$125,000. Additional savings will be seen in the earthwork (see WkBk 2.5.1). Further research may indicate a need for additional footings around the bridge structures,which would incur additional costs. Life Cycle Cost Analysis Life cycle costs are perceived as unchanged. ' Sketch of VE Recommendation ' See attached. E.

BASELINE INFORMATION ' Design Assumptions The current design requires the secant pile walls to have struts near the top of the wall. These struts are ' approximately 3' x 3' x 80' long and are spaced about 60' apart. The cost of this item is $95;000, which is about 1% of the construction cost. ' In order to eliminate the top struts, either tie-backs or a change to a thicker cantilevered wall system is required. Alternatively, if the proposed reduced roadway width with the stepped wall height is adopted, struts may not be required because the wall height is reduced. It would seem desirable to eliminate the ' struts for aesthetics and its attractive nuisance appeal to daredevils. The Draft Soils Report (pg. 11) says that tie-backs are not cost effective.

BASELINE INFORMATION Design Assumptions Given the linear alignment of South 180ffi Street and the existing railroad tracks located perpendicular to the alignment, it may be feasible to construct and jack a highway tunnel segment beneath the existing railroad alignment. The highway tunnel segment would consist of the full geometric section of the roadway. This process would eliminate the need for the shoofly, railroad bridges, and secant pile wall excavation support system in the vicinity of the completed jacked section. This construction technique is presently being used in the Central Artery Tunnel in Boston,Massachusetts(Section D09A4). To construct the highway in this manner, a jacking pit would be required,but likely located on the west side of the railroad bridges, where the future roadway would be constructed. A portion of the highway would be constructed in the jacking pit. It would be jacked forward and a subsequent highway section would then be ' constructed. This process would be repeated until the highway tunnel extended beneath the tracks. The pit would have to be dewatered which could cause settlement of adjacent structure depending upon the magnitude of the groundwater drawdown outside the excavation. Groundwater recharge could be considered. To mitigate this adverse effect, continuous settlement monitoring of the railroad tracks would be required during this construction process. Ground improvement techniques such as compaction grouting, jet grouting, or freezing would likely be required in the vicinity of the tracks to maintain grade as the tunnel ' is jacked beneath them. This option would only be pursued if it is determined to be cost-effective, as it would not eliminate ' disruption to railroad operation because of the settlement that the tracks would likely experience.

There would be no temporary shoofly tracks, but the cost of building new permanent tracks on new alignments would probably be more than for the shoofly. 1 The advantages would only be if the railroads want to change the alignments of their existing track.The disadvantage would be increased construction cost and additional curves added to the existing railroad alignment. This appears to increase the cost with no added value unless the railroads need the alignment changes and ' would pay the full cost of the new tracks.

Seal reduction y=200/6x6=5.5' of height ' Cost of reduced concrete=200ft3/27 x$85/cy=$630 The cost of piles or anchors would need to be significantly less than this to be cost effective. Cost of furnishing 50' pile @ $25/ft=$1,250 Cost of driving pile = $250 Total = $1,500 ' The installation of the piles or tie rods will present some construction difficulties with underwater placement and access problems. It doesn't appear that it would be cost effective to use driven pilling to t reduce the seal thickness. Tie rod anchors might cost less. If tie down anchors can be installed at less than about$500 each,there is probably a cost savings from reducing the tremie slab thickness. The Cypress Freeway in Oakland was a similar project (ASCE, Civil Engineering, Dec 1998, pg 46). On this project they determined that soil-cement piles was a cost-effective method to reduce the seal thickness.

BASELINE INFORMATION ' Design Assumptions ' Two alternatives were reviewed to improve the constructibility of the tremie seal including partial dewatering (combined with groundwater recharge if required) and deep soil mixing. The concern is that construction of the tremie seal in the wet in short sections is complicated and potentially costly. ' • Partial Dewatering: It may be feasible to dewater the South 180ffi street boat section to construct the base slab in the dry. We understand that there are concerns about settlement of adjacent structure as a result of the groundwater level drawdown outside the excavation if a dewatering system is utilized. This effect ' could possibly be minimized if limited areas were dewatered within the secant pile walls to correspond to construction of relatively short sections of the tremie seal base slab. As an alternative, if settlement of adjacent structures is a concern as a result of the groundwater level lowering, a groundwater recharge ' system could be considered adjacent to the settlement sensitive structures. If dewatering and/or recharge is pursued further, it is recommended that a pump test and possibly an injection test be performed to further evaluate the dewatering and groundwater level lowering potential prior to final design. ' • Deep Soil Mixing: It may be possible to replace the tremie seal with soil-cement using deep soil mixing techniques. Deep soil mixing is a process of mixing cement grout with the insitu soil (typically using ' continuous flight augers to create soil-cement. This process could be accomplished from the existing roadway surface prior to excavation. The soil-cement would create a seal that would enable the excavation to be accomplished in the dry. Upon completion of the excavation, the base slab of the roadway section could then be constructed. For this to be effective, however, the soil cement must be ' continuous and of sufficient thickness and weight to resist the hydrostatic forces. Based on the results of the subsurface explorations, it appears that the soils in the vicinity of the proposed tremie slab consist of organic and peaty deposits. These materials often prove difficult to mix into a homogeneous material. As ' a result, a continuous impermeable tremie slab may be difficult to achieve using soil mixing techniques. In addition, recent experience in the Snoqualmie Valley on a shaft excavated in alluvial soils also suggests that assuring a soil cement seal may be difficult to achieve. See the attached article on soil- cement mixing. B. OPTIONS CONSIDERED ' Creative Idea List—Tremie Seal Constructibility[Cl#38] ' C.

BASELINE INFORMATION ' Design Assumptions If temporary dewatering can be accomplished to improve tremie seal constructibility, a permanent ' "dewatered conditioned" could also be evaluated. A permanent pressure relief system could be installed . beneath the roadway section. This would reduce the base slab thickness. The disadvantages of such permanent dewatering system, however, most likely outweigh the benefits. The disadvantages include ' permanently pumping and disposing of a potentially large volume of groundwater. Back-up pumping systems and power supplies would be required. Permanent maintenance activities would also be required. In addition, the effects of permanently lowering the groundwater level in the roadway area would have to ' be evaluated relative to the adjacent structures and railroad facilities, as well as the adjacent wetlands and creeks.

BASELINE INFORMATION ' Design Assumptions ' Tie down anchors and sloping the bottom were previously discussed as ways to reduce the seal thickness. Other ways to reduce the seal thickness would be to decrease the height of the gravel backfill over the tremie seal. See also WkBk. 2.3.3. Currently it is about 5.5 ft. Every decrease in depth by 1' requires 0.42' less seal height. The weight of the gravel backfill can also be used to resist the uplift water pressure to determine the seal thickness. Per the design report,this was considered. B. OPTIONS CONSIDERED Creative Idea List—Reduce Tremie Seal Thickness [Cl#401 ' C.

BASELINE INFORMATION ' Design Assumptions The baseline design calls for an 81' clearance to the RR bridges,which included two 6'Y2'sidewalks,two 4' bike lanes, four 11' lanes, and a 12' center column section, all at the roadway grade. Design report ' estimates indicated approximately 41,000 CY of excavation above the asphalt surface. Sketch of Current Design ' See attached. ' B. OPTIONS CONSIDERED Creative Idea List—Bicycles/Pedestrians Outside Walls&Raise [Cl#4] C. ANALYSIS ' Proposed Alternative An alternative to the baseline design would be to elevate the ped/bike sections (see also WkBk 2.1.4 for walls/abutments analysis). By removing these sections from the traveled lanes, a combined ped/bike corridor could be designed with a potentially reduced 1-0' wide section. The lower cross-section would therefore be narrowed, possibly eliminating the need for the center column sections, yielding a potential span of about 54' (four 12',two 2' shy lanes and a 2' center divider). ' Advantages ' • Grading accounts for about 5% of the total construction budget in the Preliminary Cost Estimate for this project. • Elevating the ped/bike corridor and narrowing the traveled lane cross-section reduces the underpass ' cross-section by about one quarter, with the ped/bike corridor returning to grade well before the traveled lanes. • Improves safety for all non-motorized traffic by separating them from vehicular traffic. ' • Vandalism would most likely only occur on the pedestrian sections,which could be maintained without the need for interrupting traffic. ' • Improves schedule timing Disadvantages t • Less fill would also be available for the shoofly construction.

ANALYSIS Proposed Alternative The VE team recommends placing utilities within permanent easements outside the roadway. To facilitate project completion by the constraint date of January 2002,permanent easements would negate the need for relocating the utilities twice. Coordination with construction of the underpass roadway would also be avoided. Utility placement outside the roadway would benefit any future maintenance activities. If a smaller cross-section is utilized as suggested in previous workbooks (WkBks. 2.1.4 and 2.5.7), the utilities ' may be relocated either under the ped/bike elevated corridor section, or within excess ROW outside the secant walls. ' Further analysis might also determine that the gravel layer above the tremie seal could be reduced in depth.

The main line of 12"pipe will convey the flow to the underground pump station located approximately at Std. 58+15, under the sidewalk on the north side of the road. The system will have two pumps that alternate pumping runoff. This allows for even wear on both pumps and provides for a back up during maintenance or replacement of one pump. The runoff will then be pumped to the new stormwater facility located 50' north of S 180th St. and east of the tracks for water quality and water quantity control.

The following items describe the basic steps of a constructibility review and its benefits. ' Definition For the purposes of this study, "constructibility" is defined as "the ease with which a designed project can be built and the ease with which the contract documents can be understood, bid, administered, and enforced." The review team attempts to verify the clarity and completeness of the drawings and project manuals to ensure that the contractors, subcontractors and vendors bidding the project and executing the work will understand them. The documents are reviewed for pitfalls that would increase costs or cause delays to the performance of the work. When incorporated into the completed design documents, the constructibility comments will result in reduced cost, greater efficiency of bidding and construction, and improvements in the value of the project. Problems during bidding and change orders and disputes during construction should be greatly reduced. After the clarity, coverage and consistency of the documents are completed and "fine-tuned," the project should be both biddable and constructible. The Process Constructibility reviews generally examine each sheet of each discipline in the plan set. Each discipline is reviewed through the mindset of the contractor, determining how well the plans and specifications cross coordinate with other disciplines, and how well phasing is shown for each discipline. If the Design Team has developed a schedule, the schedule is reviewed to determine if adequate time has been allowed for the project and adequate consideration has been given for the project phasing. During the Constructibility Review the following questions will be addressed and resolved: • Are there improvements that can be made to help the contractor find his way around the documents more easily? ' 0 Where are the documents less than clear as to what is required? Are there gaps, ambiguities of intent? • Does the potential exist for a jurisdictional dispute between trades because of an overlap in I responsibility or a gap in responsibility over some portion of the work? • Will there be installation difficulties with any of the construction components or items of equipment? • Are there materials or labor skills specified which are difficult to acquire or unnecessarily costly? ' 2.9.1— 1of3 CITY OF TUKWILA VE WORKBOOK South 180"h Street Grade Separation `AL 0 L Y M P I C June2000 2000143 ASSOCIATES COMPANY CONSTRUCTIBILITY ' 2.9.1 —Constructibility Comments • Are there installation requirements which are unnecessarily difficult, and which could be accomplished in an easier or less costly manner? • Are there components or utility systems that are in need of better coordination? • Are there potential conflicts between drawings and specifications? ' • Are there questions of access for construction equipment or suitable staging areas? • Are the contractor work measurement and payment conditions reasonable? ' Disciplines Reviewed The disciplines reviewed for value and constructibility are usually: ' 1. General Conditions 2. Civil/Landscape 3. Architectural 4. Structural 5. Mechanical ' 6. Electrical Order of Importance ' In order to offer proper and fast access to the most important constructibility findings, all observations might have a priority weight as follows: 1-Lowpriority: Typographical error or minor omission that can be inferred from the documents, ' not likely to be misinterpreted or result in dispute or delay. 2-Medium priority: Error, omission or clarification likely to result in RFI and modest cost or time impact. 3-High priority: Significant element missing from the documents, significant mis-coordinated element, or work item open to wide interpretation by bidders. Likely to result in multiple RFI's,cost impacts and/or delays. Limitations While the Constructibility Team makes endeavors to locate and demonstrate missing, ambiguous, and "unbuildable" details and information from the document set, a 100% review is never possible. The 1 Constructibility Review is meant to supplement the Design Team's normal quality controls. Advantages ' Constructibility reviews (CR) are intended to raise questions regarding approach, techniques, systems, and methods used in development of the contract documents with the intent to make the overall project more inherently constructible, reduce the potential of change orders, and avoid project delay.

Quantifying the savings of conducting a constructibility review is difficult; however, assisting the ' Owner by avoiding one major claim could result in saving thousands ofdollars and weeks in time. Disadvantages • May delay bidding of the project.

B. OPTIONS CONSIDERED ' Creative Idea List—Confirm S 196th Detour[CI#5] ' C. ANALYSIS Proposed Alternative ' This proposal confirms the use of the new South 1961h Street overpass being constructed by the City of Kent to allow the total closure of 180`h Street between 72°d Avenue South and 80`h Avenue South. This proposal would detour traffic on 1800'Avenue to S 196`h Street and the West Valley Highway. In addition, the City ' of Renton is currently completing the missing section of Oakesdale Avenue between SW 27 h Street and SW 34`h Street. This would allow traffic to be detoured north,providing additional routing via Grady Way. There were three on-site alternatives for detouring traffic: 180'h Street North, 180`h Street South and Split ' 180'h Street. Each of these alternatives would add considerable cost and possible delay to the project. Advantages of Using S 196th As a Detour: ' • Eliminates the need to acquire additional right of way • Reduces the amount of damage to adjacent businesses ' • Improves safety of traveling public by eliminating at grade railroad crossing • Avoids the need to do additional environmental work and possible damage sensitive areas • Provides the contractor maximum flexibility to schedule construction • Eliminates the need to construct,remove temporary detour and restore property • Reduces the amount of traffic control and eliminates temporary RR signals • Reduces project cost(180d'detour option add$1,500,000) ' • Reduces time needed to construct the project by 9 months • Reduces conflict with underground utilities ' Disadvantages of Using S 196th as a Detour: • May increase traffic congestion at South 801h Street and 180'h Avenue westbound and at the West valley Highway(SR-181) and South 196'h Street Intersection.

With the tight timeline for construction completion (January 2002), it is recommended that utility relocations are expedited as soon as possible(see also WkBk 2.7.1). Either the railroad or its representatives shall perform the shoofly construction. This construction will need to be ' phased into the overall work plan to ensure completion by the January 2002 completion constraint. All bid packages (railroad, utility, underpass) need to include provisions to ensure proper schedule coordination and timely completion. The South 196`" overpass project needs to be completed by March 2001 in order to detour traffic from S 180`h.

BASELINE INFORMATION Design Assumptions Access to the Interurban Trail is located on the south side of South 180`"' Street, where the underpass ' matches grade, and switches back to connect with the proposed pedestrian bridge. Approximately 2,400 square feet of right of way is being acquired. ' Sketch of Current Design ' See attached. B. OPTIONS CONSIDERED Creative Idea List—Improve Access to Interurban Trail [Cl#21] C. ANALYSIS ' Proposed Alternative ' Create a direct route connecting to the Interurban Trail (i.e. a perpendicular ramp from South 18& Street) utilizing existing ROW easements from PSE (note this option is dependent upon implementation of the recommendation in WkBk. 2.5.1 to elevate the ped/bike section of the underpass). The Interurban Trail easement from PSE is about 15' wide (total width of the trail). Depending on the design for access from the 8' wide ped/bike corridor, no permanent ROW would need to be acquired. The recommendation for Interurban Trail access improvements is dependent upon relocation of the ped/bike corridor. Additional design costs may be seen in creating the connection ramp and from the temporary construction easements ' negotiated with PSE. Advantages ' Permanent ROW would not be needed Disadvantages • Possible additional design costs ' D. DEVELOPMENT/JUSTIFICATION Assuming a permanent ROW cost of $20/SF, the potential savings would be about $48,000. However, additional costs in construction and temporary easements may offset some of the savings. Therefore, assume savings in the range of$25,000.

The ends of this culvert were plugged when it was built in the 1980's. Using current seal depth information, the volume of the remaining 7.5' of depth provides 160,000 gallons of storage capacity. Each ' foot reduction in seal or surfacing depth would result in an additional 20,000 gallons of storage. The proposed storage capacity of the proposed detention facility is 140,000. If it is not used for drainage it could also be used as a utility corridor which would result in$10,000 cost savings.

If the ped/bike sections are elevated as suggested in WkBk. 2.5.1,the safety risk would be significantly reduced and require a simple rail for fall protection. ' In either case, consideration should be given to protecting the fascia from vandalism with graffiti-resistant paint (which would also be reduced through the raised ped/bike section). Access to the struts and railroad bridges should also be restricted on the surfaces for safety and vandalism reasons, either by chain link fence or some other means. An elevated ped/bike corridor may also require chain link or other measures to restrict overhead access to the struts and railroad bridges.

See the location map in Section 3.2. The corridor is ' classified as a principal arterial facilitating east-west vehicular traffic in the Tukwila, Renton, and Kent areas of the Green River Valley. The existing four-lane roadway serves not only local connections between SR 181 (West Valley Highway)and East Valley Highway, it is also part of a central corridor feeding State Route 167 (SR 167). Currently, South 180t' Street is the only major crossing of the railroads for 3.5 miles between Interstate 405 (I-405) and south 212`h Street. As a result, the ' existing roadway experiences high traffic volumes. The existing north-south rail corridor currently contains three sets of tracks,two to BNSF and one UPRR. These lines are heavily used for both freight and passenger service,with upwards of 60 trains per day. The intersection of these two heavily used corridors results in not only extensive traffic delays but also in ' numerous accidents. From 1996 through 1998, 24 accidents were reported on South 180`h Street. One of the accidents in 1998 resulted in two fatalities when a train hit a car. In addition, the Interurban Trail crosses South 180`h Street just west of the UPRR tracks. The trail is widely used as a walking and bicycle path. The estimated total project cost is $15,609,000. The construction contract is planned to be awarded in March 2001 and construction is to be completed in 2002.

ECOSYSTEMS TECHNICAL MEMORANDUM Tacoma-to-Seattle Commuter Rail Project Prepared for Adolfson Associates, Inc. 5309 Shilshole Avenue NW Seattle, Washington 98107 and Regional Transit Authority - 1100 Second Avenue, Suite 500 Seattle, Washington 98104 Prepared by Herrera Environmental Consultants, Inc. 2200 Sixth Avenue, Suite 601 Seattle, Washington 98121 Telephone: 206/441-9080 October 30, 1997 Tacoma-to-Seattle Commuter Rail Project—Ecosystems Introduction The purpose-of this technical memorandum is to provide the results of natural resources site investigations for a portion of the proposed Tacoma-to-Seattle Commuter Rail project. The project, which is sponsored by the Regional Transit Authority (RTA), would involve operation of commuter rail service between Tacoma and downtown Seattle on approximately 40 miles of existing Burlington Northern Rail Road (BNRR) track. Commuter rail trains would provide service to stations in Seattle, Tukwila, Renton, Kent, Auburn, Sumner, Puyallup, and Tacoma. The RTA is currently evaluating ten potential station sites for inclusion in the project. This memorandum describes existing conditions and potential impacts on significant and sensitive ecosystems, wetlands, and endangered species at ten sites proposed for development of commuter rail stations and park-and-ride facilities. Several additional project elements (station sites and track improvements) are still being considered by the RTA for inclusion in this project and are not addressed in this memorandum. Following the RTA's issuance of a final project description, these additional project elements will be analyzed in a future technical memorandum. Potential mitigation measures will be included as part of the additional analysis to be conducted after the project description is completed by the RTA. The findings of this and future technical memoranda will be combined into a final ecosystems report document. This report summarizes pertinent background information and presents the findings of site reconnaissance. General site conditions, significant and sensitive ecosystems, wetlands, and endangered species are described for each of the ten station sites. The findings presented in this technical memorandum will be summarized in the NEPA Environmental Assessment for the Tacoma-to-Seattle Commuter Rail project. This technical memorandum draws on information presented in the Preliminary Assessment of Ecosystems, Wetlands, and.endangered Species (Herrera 1994) that was prepared for the Central Puget Sound Regional Transit Authority for its South Corridor Commuter Rail project. A total of 30 station and park-and-ride sites as well as five track improvement areas were analyzed in the 1994 report. This memorandum provides an update of the previous work at nine of those sites that were selected for inclusion in the Tacoma-to-Seattle Commuter Rail project. It also includes the results of field investigations for a new station and park-and-ride lot at S. 1801h Street in Renton that was not analyzed in the 1994 study. rfl 9/Q/KluntnlG�KO1Vl/I.dO[ October 30, 1997 1 Herrera Environmental Consultants Tacoma-to-Seattle Commuter Rail Project—Ecosystems Study Methods and Assumptions The methods used to identify existing conditions, sensitive areas, and threatened and endangered species at the 10 proposed commuter rail station sites include a combination of site reconnaissance and review of background information. Each site was visited to determine if conditions have changed since previous studies for the South Corridor Commuter Rail project were conducted in 1994 (Herrera 1994). Observed changes in site conditions are noted in the station descriptions presented in this technical memorandum. Because the 180`h Street Station site in Renton had not been previously studied, it was evaluated in more detail to determine the presence and exact boundaries of wetland areas that could affect station layout and design. Wetland delineation field forms and the boundary survey map for this site are included in Attachment A. Wetland delineations were conducted in accordance with the U.S. Army Corps of Engineers Wetland Delineation Manual(U.S. COE 1987) as required for . federal and local government permits. Sources of background information used to describe existing environmental conditions at the proposed station sites included National Wetland Inventory maps, Washington Department of Fish and Wildlife Priority Habitat and Species Program data, Washington Department of Natural Resources Natural Heritage Program data, and maps of environmentally sensitive areas provided by local jurisdictions (e.g., King County, Pierce County, and the cities of Renton, Tukwila, Auburn, Sumner, Puyallup, and Tacoma). Existing information on environmentally sensitive areas and significant natural resources at the selected sites (e.g., threatened or endangered species or priority habitats) is summarized in Table 1. Observations made during site reconnaissance, together with available background information, were used to confirm the presence or absence of sensitive areas and important natural resources at the selected sites. ry! 9/6hechnnndreoirmtidec October 30, 1997 2 Herrera Environmental Consultarits Tacoma-to-Seattle Commuter Rail Project—Ecosystems Table 1.

Site investigations indicate that three wetland areas occur in the area intended for station development (Figure 8). However, the exact station layout for this site is still being developed by RTA and is not included in this technical memorandum. Impacts to natural resources at this site will be analyzed when the station layout becomes available and will be included in a future technical memorandum to the RTA. Because the site is comprised of several properties, the wetland information presented in this report is an aggregate of two separate field investigations conducted at the request of the property owners. Herrera staff delineated wetlands A and B on September 30, 1997. The wetland delineation-data forms and boundary survey map are included in Appendix A. Wetland C was . delineated by Watershed Dynamics (1996). The parcel to the south of S. 180`h Street may be proposed for future parking lot expansion but, at the request of RTA, was not included in the field investigations for this report. Areas to the north of S. 180`h Street that are proposed for station development encompass several distinct plant communities. Wetland B is part of a large wetland system that extends off-site to the north, where it also encompasses scrub/shrub, emergent, and open water classes that are hydrologically connected to Springbrook Creek. Dominant vegetation in the portion of wetland B that occurs on the station site includes a tree canopy of black cottonwood, Oregon ash, and red alder; a shrub layer of red-osier dogwood, Himalayan blackberry, evergreen blackberry, salmonberry, hardhack, and red elderberry; and herbaceous species such as reed canarygrass, creeping buttercup, field horsetail, herb Robert, and bittersweet nightshade. A fringe of emergent wetland vegetation occurs along the southern edge of this forested wetland that is comprised of reed canarygrass and scattered Oregon ash trees. Wetland A in the southwest corner of the site is an isolated scrub/shrub wetland that is confined to a swale paralleling the BNRR tracks. The dominant vegetation in this wetland includes Pacific willow, red-osier dogwood, hardhack, and reed canarygrass. It is being invaded by Himalayan blackberries. Surface water runoff collects in this swale and is contained by the steep banks for South 180th Street and the railroad tracks. A large blackberry thicket dominates the south central portion of the site between wetlands A and B. Site topography and observed soil characteristics suggest that fill material was placed where the Himalayan blackberry thicket exists, separating Wetland A from the larger wetland B complex. It appears that a house with ornamental plants used to occupy this fill area as evidenced by the presence of cherry trees, English ivy, red elderberry, and blackberries. A forested wetland (wetland C) to the east of the existing access road likely was also connected to the larger wetland B system before the access road was built. A mature row of poplar trees along the east side of the access road appears to be approximately 50- to 75-years old, indicating that these wetlands have been functioning as separate systems fora long time. / 9/MaMr�onrzwdot October 30, 1997 15 Herrera Environmental Consultants I I 1 1 INKLER I I 1 --- ' I 1 V) 1 1 10 I 1 Z O I 1 38TH 1 1 I AMDLA ' 180th Street ° 39TH I , ' I 1 Station SAXON O 41ST TRILAN I I 1 1 1 1 I � 180TH Co 43RD - BEdALEP1(R R'D in MST , 1 / r ' I I RStpE 182ND 1 / T�DD 1 1 184TH y �v 1 ' Q w SFF P M � � t ^ I � 1 GLACIER t 186TH r ' I ' 1 ' 188TH 1 ' BTTH I 1 I ' I i 1 ' 190TH i N HERRERA Source: Thomas Bros.

Locations of wetlands at 180th Street Station. Tacoma-to-Seattle Commuter Rail Project—Ecosystems Because wetland B is a large forested and open water wetland complex that extends offsite to the north, it provides excellent habitat for numerous small birds, mammals, and amphibians. Two great blue heron rookeries are identified within 1.5 to 2 miles of the site and it is likely that these large wading birds use the more northerly parts of this wetland system where shallow water and adjacent shrub cover provides habitat for the heron's favored prey of frogs, small fish, mice and aquatic insect`s. Wetlands A and C are of lesser quality for wildlife habitat because of their smaller site The 1801h Street station site is located in close proximity to Springbrook Creek, a tributary to the Black River and part of the Green River drainage. The creek is located immediately to the east of the station site in a steep-banked channel that meanders in a northerly direction to its confluence with the Black River. Springbrook Creek is identified by the Priority Habitats and Species map (WDFW 1994) as providing important fish habitat for anadromous fish runs. The Catalog of Washington Streams and Salmon Utilization (WDF 1975) identifies Springbrook Creek as habitat for Coho salmon. The station is also within 1,500 feet of the Green River, which is also important anadromous fish habitat and supports listed resident fish species. Potential Environmental Impacts Impacts to natural resources at the 180`h Street Station will be analyzed in a future technical memorandum when the final station layout is completed. �l 9/dA erMuwderona�dx October 30, 1997 18 Herrera Environmental Consultants Tacoma-to-Seattle Commuter Rail Project—Ecosystems References Herrera Environmental Consultants, Inc. 1994.

In return, Zelman will grant the City a 100 foot drainage easement and a 225 foot ingress/egress easement along the southwest portion of the site. RECOMMENDATION: The Planning/Building/Public Works Department recommends approval of the wetland buffer averaging easement in exchange for ingress/egress and drainage easements to be granted by Zelman. BACKGROUND: As part of the development of Phase II of the Oakesdale Business Park, the Planning/Building/Public Works Department proposes to grant the developer, Zelman an easement on City property for buffer averaging. The easement for buffer averaging is necessary to mitigate for 21,370 square feet of wetland buffer, which will be used as parking for the business park along the western margin of the site. The City property was purchased by the Surface Water Utility from the Glacier Park Company in 1992. After reviewing the developer's buffer averaging plan, the City is satisfied that the plan is in conformance with Section 4-3-110-J7 of the City's Wetland Regulations. The buffer averaging is to occur between two existing wetlands on the South end of City owned property west of the Oakesdale Business Park. Buffer averaging will not be allowed on the South 200 feet of City property. In exchange for the City granting the buffer averaging easement, Zelman will grant the City a ingress/egress easement and a drainage easement. The ingress/egress easement will provide primary access off of SW 43rd Street onto City property. The easement is 225 feet in length and 45 feet wide and extends north-south along the southwest corner of the Oakesdale property. King Park, President/Membe, .'the City Council 4/14/99 Page 2 The drainage easement will allow the City to connect the existing box culvert buried under SW 43rd Street to Springbrook Creek sometime in the future. The drainage easement is defined as the area over the south 100 feet of the Oakesdale site between the Drainage District No. 1's west right-of-way boundary of Springbrook Creek and the Site's western property boundary, Attachments CC: Lys Hornsby l l:\DI V I S I ON.S\UT I L ITI f.S\DOC S\1999\2\99-172.DOC\AQ\tb Return Address: City Clerk's Office City of Renton 1055 S Grady Way Renton, WA 98055-3232 Title: EASEMENT Property Tax Parcel Number: 362304-9111 Project File#: Oakesdale Business Park Street Intersection: SW 43rd St,West of Oakesdale Ave SW Grantor(s): Grantee(s): 1.

There are several key concepts that have been agreed upon and which we will continue to pursue. I want to express my appreciation to all of you and your staffs for their ongoing hard work on this challenging project. Who Pays for What? ➢ Jim Morrow and I agreed to follow the funding approach established in CAG 046-86, the Renton/Tukwila Interlocal Agreement regarding Reciprocal Annexations. This approach requires Renton and Tukwila to split local costs (costs not covered by grants, partner contributions, etc.) 50%/50%. This will apply to not only the S. 180`h/SW 43r Street project managed by Tukwila, but the Strander/SW 27`h Street extension project managed by Renton. Jim Morrow and I will shortly exchange letters to confirm this understanding. Mayor Tanner endorses this approach. ➢ A Tukwila staff member quoted me Tukwila local dollar contributions of about $400,000. 1 am not sure how accurate this is, and am waiting for a better break down from Jim Morrow. Tukwila would like us to pay for the water and sewer line relocations, which have been roughly estimated to cost $410,000 for water and $142,000 for sewer. I told Jim that under this funding scenario, Renton would pay for the pipeline relocations up to the amount that matches Tukwila's local funds expenditure, and after that costs would be split equally between the two jurisdictions. I also mentioned that Renton will count in-kind contributions, specifically land, against Renton's cost participation in this project. ➢ I mentioned to Jim Morrow that starting in 2002 Renton will start paying local share money for the $750,000 needed for the design and permitting for the Strander/SW 27`h Extension project because we will have run through the obligated federal STP grant funding by then. Therefore Tukwila could start needing to cost share for that project as early as 2002. However, if Tukwila accepts $3.4 million being offered by Sound Transit and thereby frees up $3.4 million of STP funding for the rest of the region, much if not all of the $750,000 needed for the Strander extension project would be federal money. (I mentioned this to Jim to add some incentive for Tukwila to accept the Sound Transit money. However, Jim mentioned that Sound Transit was attaching strings to the money, and negotiations are moving slowly). DocumenQ\cor e Page 2. ➢ Funding for the water and sewer line relocations will for now come from the Utilities Capital (421) fund, so this needs to be inserted into the revised CIP that we will soon be bringing to Utilities Committee. When I briefed Mayor Tanner about this approach, he immediately asked the right question: this is not a utility project, so will transportation funds reimburse the Utilities Capital (421) fund? The answer is yes, reimbursement funding must be programmed into the 2002 TIP (Sandra, for your tickler file. I have a feeling you will be reminded). Mayor Tanner supports this approach. Property Issues ➢ I went through with Ma orTanner the property donations required from the City. The property fronting SW 43 west of the Oakesdale Office Park is owned by the City. Tukwila intends to site a storm water pump station and detention/water quality facility on this property. In addition, Tukwila would like to use this property to provide wetland mitigation for the project. There is currently an encumbrance(I believe 20,000 square feet)that needs to be set aside for wetland buffer associated with the Oakesdale Office Park. Fitting in the buffer,the surface water facilities, and wetland mitigation may be challenging. The Mayor's perspective: 1) obtain cost participation credit for Renton property used for the project, 2) Tukwila should operate, own, and maintain the storm water facilities on the site, and their access should be provided via an easement or access agreement, 3) If there is not enough room for the buffer encumbrance and the wetland mitigation, a site in Tukwila should be investigated for the wetland mitigation. ➢ Jim Morrow pointed out that the project will need to use the drainage easement across the SW 43`d Street frontage of the Oakesdale Business Park to route the water and sewer lines, as well as gas and electricity. Jim asked Renton to check whether this drainage easement will allow installation of other utilities. (Ron, can you find out about this?) If not, he would like to negotiate with the business to site the water and sewer lines while at the same time have Renton begin to work on condemnation so that time will not be lost if access cannot be successfully negotiated with the Oakesdale Business Park. Tukwila and Kent have similar negotiations going on across the street on the Kent side. ➢ Is the driveway being installed off of SW 43`d Street right-in/right-out only, or is it all directions? (Neil, maybe you can find this out). ➢ Part of the retaining wall along the north side of SW 43`d will be in City property. Jim Morrow suggested that this piece should be dedicated to the City of Renton as right-of-way. However, I suggested that another approach would be to place that portion of the wall into an easement, similar to what we do with sidewalk easements. This would perhaps be equally effective and less work. ➢ Jim Morrow also mentioned that he is waiting for a letter from the City regarding options on the 20,000 square foot wetland buffer on the city property. He would like this buffer to be moved to accommodate the storm water facilities and the proposed wetland mitigation work. I believe this pretty well covers issues outstanding at this time on this complicated project. Oh yes, Tukwila still intends to start construction in Spring, 2001, so they are interested in keeping the project moving. Please share this information with others working on the project. Thanks.

(BERGER/ABAM)for the South 180th Street Grade Separation project. The project is located at the intersection of the northwest corner of the city of Kent,the southwest corner of the city of Renton and the eastern boundary of the city of Tukwila,Washington,in the vicinity of the Burlington Northern Sa nta Fe (BNSF) and Union Pacific Railroad(UPRR)tracks(in Township 23N, Range 4E,north half of Section 36). A vicinity map is provided as Figure 1. Along South 180th Street,the study area extends 200 feet north and south of the roadway from 72nd Avenue South on the west side to 80th Avenue South on the east side. Along the BNSF and UPRR tracks,the study area extends 1,000 feet north and south of the tracks and within 100 feet of the railroad right-of-way. A map of the study area is provided as Figure 2. In compliance with federal and local wetland regulations for Kent, Renton and Tukwila, BERGER/ABAM completed this study in order to determine the presence, extent, and characteristics of wetlands in the study area. In addition BERGER/ABAM has completed an impacts analysis and provided preliminary conceptual mitigation scenarios in order to mitigate for unavoidable filling and disturbance of wetlands,wetland buffers and riparian buffer areas within the study area. A wildlife study and stream study have been prepared for the South 180th Street Grade Separation project under separate cover, entitled South 189th Street Grade Separation Project Wildlife Study (BERGER/ABAM Engineers Inc., 1998)and South 189th Street Grade Separation Project Stream Study. 2.0 SITE DESCRIPTION Land uses within the project study area include a mix of commercial, office park, and light industrial uses. Other land uses on the north side of South 180th Street include: an undeveloped property located immediately east of the BNSF right-of-way; and the proposed Oaksdale Business Campus site east of the undeveloped property and extending to 80th Avenue South,which has been cleared and is currently undergoing site cleanup for contaminated soils. During field investigations, construction was underway on the south side of the roadway on the Creekside Storage Park, a public storage site immediately east of the BNSF railroad tracks. The Interurban Trail, Puget Sound Energy power lines,fiber optic cable, and a gas line cross the project study area. Springbrook Creek flows from northeast in the eastern portion of the project study area. Mill Creek flows northeast under a bridge over the BNSF railroad tracks to a confluence with Springbrook Creek in the southeastern portion of the site(see Figure 2). The project study area is generally flat, with elevated grades for the roadway and the railroad tracks. Vegetation within the project study area includes the following: ■ Scrub-shrub wetland areas dominated by willows and open water between the BNSF and UPRR tracks and between the UPRR tracks and the Interurban Trail,on the northern side of the roadway ■ Blackberry thickets along the Interurban Trail along both sides of the roadway and in the southern half of the undeveloped site on the northern side of the roadway, adjacent to the BNSF railroad tracks Draft Wetlands Study South 180th Street Grade Separation 1 April 1999 4 W North 405 5 Renton 518 Sea-Tac International Project Airport Area = S 180th Tukwila 161 167 S 212th Kent 5 161 167 Source: Vicinity Map BERGER/ABAM Engineers 1997 South 180th Street Grade Separation Figure 1 use S v ■ = ~r - 30 25am &BM . . - `i 'Tukwila = F a Green i /• CORP 4 Sul project Area '� ••" ,. 4 43 E I �.� r • �f a■r .. i IF . + .... / , 1 1 N ■ Subs , IM r o Not to Scale North Source: Project Study Area U.S.G.S.Renton,Washington Quadrangle, 1994 South 180th Street Grade Separation Figure 2 ■ Weed and reed-canary grass-dominated areas on the south side of the roadway between the BNSF and UPRR tracks ■ A small forested area dominated by bigleaf maple within the northwestern portion of the remediation site; and a small forested area with bigleaf maple and locust south of the public storage site ■ A willow-dominated corridor adjacent to Springbrook Creek on both sides of the roadway A list of the plant species found within the project study area is shown in Appendix A. 3.0 PROJECT DEVELOPMENT 3.1. Preferred Grade Separation Design Alternative The proposed roadway will consist of four 11-foot through lanes,two in each direction,with a 12-foot center lane for the length of the project. This center lane will serve as a turning lane at the beginning and end of the alignment. As the roadway passes under the tracks,the piers supporting the new bridges will be located in the center lane. The center piers will be drilled shafts approximately 4-inches in diameter. To accommodate bicyclists, a 4-foot shoulder will be constructed along both sides of the road. A 6-foot concrete sidewalk will extend for the length of the project on both sides. Due to significant change in grade along the corridor,extensive reconstruction of private access driveways is required on both sides of the tracks. The project will add approximately 0.5 acre of new impervious surface to the site. Stormwater runoff will be collected by catch basins at the gutter on both sides of the roadway. A 12-inch mainline will convey the flow through an underground pump station to a new stormwater facility located 50-feet north of S. 180`h Street and east of the tracks for water quality and water quantity control. Discharges from the new facility will be discharged into a detention pond consisting of two cells separated by a berm,then to Springbrook Creek. An emergency overflow was provided in the detention pond to discharge 100-year flow for developed condition. 4.0 METHODOLOGY 4.1 Wetland Definition Wetlands are formally defined as"... those areas that are inundated or saturated by surface or groundwater 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 soil conditions. Wetlands generally include swamps,marshes,bogs, and similar areas." (Federal Register, 1980, 1982). 4.2 Wetland Delineation Requirements The wetland delineation was conducted using the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987)(Corps manual)as required by the U.S. Army Corps of Engineers (Corps)and the cities of Tukwila, Renton, and Kent. In February 1997,the Washington State legislature adopted the Washington State Wetlands Identification and Delineation Manual (Ecology Manual) and require its use by local jurisdictions. This new manual is consistent with, although not identical to,the Corps manual. Draft Wetlands Study South 180th Street Grade Separation 4 April 1999 According to both manuals, an area must exhibit indicators of hydrophytic vegetation,hydric soils, and wetland hydrology to be considered a wetland. These criteria are mandatory and must all be met for an area to be identified as wetland, except under circumstances when a wetland is considered a disturbed area or problem wetland. These criteria are discussed below. Vegetation Hydrophytic vegetation is defined as macrophytic plant life growing in water, soil, or substrate that is periodically deficient in oxygen. For each plot,the percent areal coverage is estimated for each plant species present, and dominant species is determined. Species are assigned a Wetland Indicator Status(Reed, 1988),which is based on the estimated probability of each plant species'occurrence in wetlands or nonwetland(see Table 1). Table 1. Wetland Indicator Status Wetland Indicator Estimated Probability of Status Description Being Found in a Wetland OBL Obligate: species that almost always occur in >99% wetlands under natural conditions. FACW Facultative Wet: species that usually occur in 67% > 99 % wetlands but are occasionally found in nonwetlands. FAC Facultative: species that are equally likely to 34%> 66% occur in wetlands or nonwetlands. FACU Facultative Upland: species that usually occur 1% > 33% in nonwetlands but are occasionally found in wetlands. UPL Obligate Upland: species that almost always < 1% occur in nonwetlands under normal conditions. NL Not Listed: species that are not listed and are resumed to be upland species. NI No Indicator Status: species that have not yet been evaluated. (adapted from Reed, 1988.) The indicator status of the dominant species within each vegetative unit(tree, shrub,herb)is used to determine if the plant community of an area is characterized as hydrophytic. If 50 percent or greater of the dominant plants in a unit have an indicator status of OBL, FACW, or FAC,the vegetation is considered to be hydrophytic in both manuals. Common plant names are used throughout this text. Scientific nomenclature of all plant species encountered follows that of Flora of the Pacific Northwest(Hitchcock& Cronquist, 1973). Where the taxonomic names of plant species have been changed since 1973,plant names follow the 1988 list of synonymies(Reed, 1988,revised 1993). Soils The King County Soil Survey(Snyder,D.E., P.S. Gale, and R.F. Pringle, 1973) and Hydric Soils list (Soil Conservation Service, 1985)were consulted for the presence of mapped hydric soils within the project area. Soils were assessed in the field by examining soil for hydric indicators to a minimum depth of 18 inches with a soil auger. Soil characteristics examined include hue,value, and chroma, Draft Wetlands Study South 180th Street Grade Separation 5 April 1999 as identified on a Munsell soil color chart(Munsell Color, 1992). Hydric soil indicators include mottles,low soil chroma,gleying, and high organic content. Mottles are spots or blotches of contrasting color occurring within the soil matrix. Gleyed soils are predominantly neutral gray in color. Hydrology Wetland hydrology is defined as permanent or periodic inundation or soil saturation,to within 12 inches of the soil surface,for a significant period(usually a week or more)during the growing season (Environmental Laboratory, 1987). Where positive indicators of wetland hydrology are observed,it is assumed that wetland hydrology occurs for a significant period of the growing season. Direct indicators of wetland hydrology include areas of ponding or soil saturation. Indirect indicators include dry algae on bare soil,water marks on soil or leaves, drift lines, oxidized root channels associated with living roots and rhizomes, sediment deposits, and drainage patterns. Duration of inundation and/or soil saturation for the Ecology Manual is based on the number of days during the growing season that are at 32'Fahrenheit(0°Centigrade)or above. Wetlands in the Pacific Northwest area must have 26 days of continuous saturation or inundation within the growing season to meet the criteria for wetland hydrology. Within the study area,direct and indirect indicators of wetland hydrology were recorded on data sheets and described. Method The"routine on-site determination method"was used to delineate wetlands within the study area. This method is used for areas equal to or less than 5 acres in size, or for larger areas with relatively homogeneous vegetative,soil, and hydrologic properties. A combination of field indicators, including vegetation, soils, and hydrology were used to determine wetland edges. Sampling results for the three criteria were analyzed to make a wetland determination for each plot. Based on the results of plot determinations and visual observation of site characteristics, an overall assessment of the area was conducted and wetland boundaries were located. For all wetland plots identified, data for a corresponding upland plot was collected to confirm the edge of the wetland. Wetland Data Forms are included as Appendix B. Wetland boundaries were identified with sequentially numbered pink colored flagging. Wetland flagging was surveyed by CTS Engineers, Inc. 4.3 Review of Existing Information Prior to conducting field evaluations,existing literature, maps, and other materials were reviewed to identify potential wetlands within the study area. This information included the following: ■ City of Tukwila Sensitive Areas Maps (City of Tukwila, 1997) ■ City of Renton Wetland Inventory Maps (City of Renton, 1991) ■ City of Kent Wetland Inventory Maps (1996) ■ Renton,Washington topographic quadrangle(USGS, 1994) ■ National Wetland Inventory Map, Renton quadrangle(USFW, 1988) ■ Soil Survey of King County Area, Washington (Snyder et al, 1973) ■ Hydric Soils of the State of Washington (Natural Resources Conservation Service, 1985), Draft Wetlands Study South 180th Street Grade Separation 6 April 1999 ■ Washington State Department of Natural Resources Natural Heritage Information System Database (1998) ■ Washington State Department of Fish and Wildlife Non-Game Priority Habitats and Species Database(1998) ■ Ecosystems Technical Memorandum: Tacoma-to-Seattle Commuter Rail Project(Herrera Environmental Consultants, 1997) ■ Preliminary Site Plan, Oaksdale Business Campus(CNA Architecture, 1998) ■ Preliminary Draft Grading and Storm Drainage Plan, Creekside Storage Park(Barghausen Consulting Engineers, 1997) Wetland Mapping National Wetland Inventory The National Wetland Inventory(NWI)maps portions of three wetlands within the study area (Figure 3). A Palustrine Forested Temporarily Flooded wetland(PFOA)lies within the northwest portion of the study area; a Palustrine Scrub-Shrub Seasonally Flooded,Excavated wetland(PSSCx) lies between the railroad tracks; and a Palustrine Emergent Seasonally Flooded wetland (PEMC)is associated with Mill and Springbrook creeks. City of Tukwila Sensitive Areas Mans The City of Tukwila Sensitive Areas Maps,dated 1997, depicts one wetland(Wetland 12)within the study area(see Figure 4)extending from the eastern right-of-way of the UPRR tracks,north and west of the project area. City of Renton Wetland Inventory Mans The City of Renton Wetland Inventory Map (Jones & Stokes, 1991) and the City of Renton Wetland Inventory Update (Jones& Stokes, 1996),depict Wetland 45 within the project area located on the north side of South 180th Street and on the east side of the BNSF railroad right-of-way(Figure 5). This wetland corresponds to"Herrera Wetland A"(see below). City of Kent Wetland Inventory Maps The City of Kent Wetland Inventory (City of Kent, 1996), depicts a wetland associated with the riparian corridors of both Springbrook Creek and Mill Creek within the study area(Figure 6). Tacoma-to Seattle Commuter Rail Project Wetlands Two wetlands were previously delineated within the study area north of South 180th Street and east of the BNSF railroad right-of-way and described in a report titled Ecosystems Technical Memorandum: Tacoma-to-Seattle Commuter Rail Project(Herrera Environmental Consultants, Inc., 1997). These wetlands are referred to in this report as"Herrera Wetland A"and"Herrera Wetland B"and shown in Figure 7. Both wetlands were delineated on September 30, 1997 using the Corps Manual and are described in Section 4.0 below.

The NRCS,in cooperation with the National Technical Committee for Hydric Soils,has compiled lists of hydric soils of the United States (SCS, 1985, 1987). These lists identify soil series mapped by the NRCS that meet hydric soil criteria. The Soil Survey of King County Area, Washington (Soil Survey)maps Woodinville silt loam(map symbol—Wo)as the dominant soil within the study area(Figure 8). Other soils include Puget silty clay loam(map symbol—Pu)in the northern portion of the study area,Newberg silt loam(map symbol—Ng)in the southeastern portion of the study area, Puyallup fine sandy loam(map symbol— Py) along the Springbrook Creek riparian corridor, and Urban Land(map symbol—Ur)in the southwestern portion of the study area. The Woodinville series consists of poorly drained soils that formed in alluvium on stream bottoms with a typical profile as a gray silt loam with layers of peaty muck extending from the surface to a depth of 38 inches. Permeability is moderately slow,runoff potential is slow,erosion hazard is slight, and flooding potential is severe unless flood protection is provided. Available water-holding capacity is high and there is a seasonally high water table at or near the surface (Snyder, et al, 1973). Woodinville silt loam is classified as a hydric soil(SCS, 1985, 1987). The Puget series consists of poorly drained soils that formed in alluvium with a typical profile that is dominantly mottled dark grayish brown and grayish brown silty clay loam from the surface to a depth of 60 inches. Permeability is slow, runoff potential is slow to ponded,erosion and slippage hazard is slight,flooding potential is severe, and available water-holding capacity is high(Snyder, et al, 1973). Puget silt loam is classified as a hydric soil (SCS, 1985, 1987). The Puyallup series consists of well drained soils that formed in alluvium with a typical profile as very dark grayish brown and dark grayish brown fine sandy loam from the surface to a depth of 34 inches. Permeability is moderately rapid,runoff potential is slow,erosion and slippage hazard is slight,flooding potential is slight to severe, and available water-holding capacity is moderately high (Snyder, et al, 1973). Puyallup fine sandy loam is not classified as a hydric soil (SCS, 1985, 1987). The Newberg series consists of well drained soils that formed in alluvium with a typical profile as very dark grayish brown silt loam and very fine sandy loam from the surface to a depth of 20 inches. Permeability is moderate,runoff potential is slow, erosion and slippage hazard is slight,flooding potential is slight to severe, and available water-holding capacity is high(Snyder, et al, 1973). Newberg silt loam is not classified as a hydric soil(SCS, 1985, 1987). Urban land is soil that has been modified by disturbance of the natural layers with additions of fill material several feet thick to accommodate large industrial and housing installations. In the Green River Valley,the fill ranges from about 3 to more than 12 feet in thickness, and from gravelly sandy loam to gravelly loam in texture. The erosion hazard is slight to moderate(Snyder, et al., 1973). Urban land is not classified as a hydric soil(SCS, 1985, 1987). Natural Heritage Program Data Base Washington State Department of Natural Resources Natural Heritage Program data base was searched for information on significant natural features within the study area. No records for rare plants or high-quality ecosystems were found for the study area vicinity.

The results of this investigation are discussed in the Wildlife Study prepared for the project(BERGER/ABAM Engineers Inc., 1998). 5.0 WETLAND INVESTIGATION AND DETERNIINATION A field survey to identify and delineate wetlands within the study area was conducted by Senior Ecologists Gail Brooks and Keith Fabing on July 16 and 20, 1998. Observations of topography, vegetation, soils, and hydrology identified four wetlands within the study area boundaries. Two formal data plots were established within relatively uniform areas of vegetation for each wetland within the study area. Data forms,which correspond to formal data plots, are provided in Appendix B. The wetlands found within the study area are shown in Figure 9. 5.1 Wetland A Wetland A is located in the city of Tukwila on the north side of South 180th Street within a wide swale that runs north/south between the BNSF and UPRR rights-of-way and extends north beyond the study area boundaries. The total area of Wetland A is estimated to be greater than 1 acre. The wetland is represented by Data Plot#Al in Appendix B. Vegetation The dominant vegetation species within Wetland A include Sitka willow(Salix sitchensis, FACW) and black cottonwood(Populus balsamifera, FAC)in the tree layer. The shrub layer was dominated by Douglas spirea(Spiraea douglasii, FACW). Broad-leaved cattail(Typha latifolia, OBL),water smartweed(Polygonum amphibium, OBL),velvet grass (Holcus lanatus, FAC), and field horsetail (Equisetum aruense, FAC)dominated in the herb layer. Based on a dominance of species rated Facultative or wetter,vegetation in the wetland is considered hydrophytic. Soils Soils in Wetland A were mapped as Woodinville silt loam by the NRCS(Snyder et al, 1973). The soils sampled in the wetland at 10 inches in depth within the A-horizon were dark grayish brown (10YR 4/2) silty clay with yellowish brown mottles from the surface to a depth of 18 inches. Grey gleyed(N5/)silty clay soils were observed below 18 inches in depth. These soils were considered hydric due to a low chroma with mottles within 10 inches of the surface. Hydrology The sources of hydrology to Wetland A include direct precipitation, surfacewater runoff from adjacent areas, a high groundwater table, and potential stormwater from north of the study area. A culvert is located at the southern end of the wetland, adjacent to the South 180th Street railroad crossing. The wetland was inundated in areas to depths varying from several inches to two feet at the time of the site investigation. Soils sampled within the data plot were moist to the surface. Classification and Rating According to the wetland classification system established by the USFWS(Cowardin et al, 1979), which is the current federal standard for classifying wetland habitat,Wetland A is classified as a Draft Wetlands Study South 180th Street Grade Separation 15 April 1999 i i d Ity O QfI4( c'IIN Wetland 1 t r (Approximate Y C1� ttfln} /�z� W. d R �.

This wetland would likely be classified as Type 2 wetland by the City of Tukwila, because it is estimated to be greater than 1 acre in size,is subject to disturbance, and has no critical habitat or threatened/endangered species(City of Tukwila, 1997). 5.2 Wetland B Wetland B is located in Tukwila on the north side of South 180th Street within a wide swale that runs north/south between the UPRR right-of-way and the Interurban Trail and extends north beyond the study area. The total area of Wetland B is estimated to be greater than 1 acre. The wetland is represented by Data Plot#B1 in Appendix B. Vegetation The dominant vegetation species within Wetland B include red elderberry(Sambucus racemosa, FACU), Himalayan blackberry(Rubus discolor,FACU), and red-osier dogwood(Cornus stolonifera, FACW) in the shrub layer; and reed canary-grass(Phalaris arundinacea, FACW),(Polygonum amphibium, OBL), and bigroot(Marah oreganus,NL)in the herbaceous layer. Based on a dominance of species rated Facultative or wetter,vegetation in the wetland is considered hydrophytic. Soils Soils in Wetland B were mapped as Woodinville silt loam by the NRCS (Snyder et al, 1973). The soils sampled in the wetland at 10 inches in depth within the A-horizon were grey gleyed N4/muck from the surface to a depth of 18 inches. These soils were considered hydric due to low chroma and gleying within 10 inches of the surface. Hydrology Like in Wetland A,the sources of hydrology to Wetland B include direct precipitation, surfacewater runoff from the adjacent areas, a high groundwater table, and potential stormwater from north of the study area. The wetland was inundated throughout much of its area within the study area to depths varying from several inches to 2 feet at the time of the site investigation. Soils sampled within the data plot were saturated. Classification and Rating According to the wetland classification system established by the USFWS(Cowardin et al, 1979), Wetland B is classified as a palustrine scrub-shrub/palustrine emergent(PSS/PEM)open water wetland. This wetland would likely be classified as a Type 2 wetland by the City of Tukwila,because it estimated to be equal to or greater than 1 acre in size within and beyond the study area,is subject to disturbance, and has no critical habitat or threatened/endangered species (City of Tukwila, 1997). 5.3 Wetland C Wetland C is located in Tukwila on the south side of South 180th Street within a depression that runs north/south between the BNSF and UPRR rights-of-way. The wetland is represented by Data Plot#C1 in Appendix B. Draft Wetlands Study South 180th Street Grade Separation 17 April 1999 Vegetation The dominant vegetation species within Wetland C are field horsetail(Equisetum arvense, FAC), reed canarygrass(Phalaris arundinacea, FACW), and bigroot(Marah oreganus,NQ in the herbaceous layer. Based on a dominance of species rated Facultative or wetter,vegetation in the wetland is considered hydrophytic. Soils Soils in Wetland C were mapped as Woodinville silt loam by the NRCS (Snyder et al, 1973). The soils sampled in the wetland at 10 inches in depth within the A-horizon were very dark graysih brown(10YR 3/2)silty silt loam with yellowish brown UOYR,4/6)mottles from the surface to a depth of 18 inches. Dark graysih brown(10YR 4/2) silty silt loam soils were observed below 12 inches in depth. These soils were considered hydric due to a low chroma with mottles within 10 inches of the surface. Hydrology The sources of hydrology to Wetland C include direct precipitation and surfacewater runoff from the adjacent areas. Soils sampled within the data plot were dry at the time of the field investigation. However, given the low matrix color with the presence of mottles and the sustained dry summer weather conditions,wetland hydrology during the growing season was assumed to be sufficient to meet the wetland hydrology criteria. Classification and Rating According to the wetland classification system established by the USFWS(Cowardin et al, 1979), Wetland C is classified as a palustrine emergent(PEM)wetland. This wetland would likely be classified as a Type 3 wetland by the City of Tukwila,because it equal to or less than 1 acre in size and has two or fewer wetland classes,(City of Tukwila, 1997). 5.4 Wetland D Wetland D is located in Tukwila on the north side of South 180th Street within a wide swale that runs north/south between the Interurban Trail and the commercial/industrial properties beyond the western boundary of the study area. Wetland D extends towards the west and north beyond the study area boundaries. The total area of Wetland D is estimated to be greater than 1 acre. The wetland is represented by Data Plot#D1 in Appendix B. Vegetation The dominant vegetation species within the shrub layer of Wetland D include Himalayan blackberry (Rubus discolor, FACU),with Pacific willow (Salix lasiandra, FACW+), and sitka willow in the northern portion; and reed canarygrass(Phalaris arundinacea, FACW),field horsetail(Equisetum arvense,FAC), and Canada thistle(Cirsium arvense, FACU+)in the herbaceous layer. Based on a dominance of species rated Facultative or wetter,vegetation in the wetland is considered hydrophytic. Soils Soils in Wetland D were mapped as Woodinville silt loam by the NRCS(Snyder et al, 1973). The soils sampled in the wetland at 10 inches in depth within the A-horizon were dark gray(10YR 4/1) Draft Wetlands Study South 180th Street Grade Separation 18 April 1999 silty muck with dark yellowish brown(10YR 3/6)mottles from the surface to a depth of 18 inches. These soils were considered hydric due to a low chroma with mottles within 10 inches of the surface. Hydrology The sources of hydrology to Wetland D include direct precipitation, a high groundwater table, and surfacewater runoff from the adjacent areas. Soils sampled within the data plot were saturated to the surface at the time of the field investigation. Classification and Rating According to the wetland classification system established by the USFWS(Cowardin et al, 1979), Wetland D is classified as a palustrine emergent(PEM/PSS)wetland. This wetland would likely be classified as Type 2 wetland by the City of Tukwila,because it is greater than 1 acre,is subject to disturbance, and has no critical habitat or threatened/endangered species(City of Tukwila, 1997). 5.5 Herrera Wetland A Herrera Wetland A is located in Renton in the southwest corner of the parcel located east of the BNSF and north of South 180th Street. The area of this wetland was estimated to be approximately 5 acres in size within the study area. This wetland is described as an isolated scrub-shrub wetland that is confined to a swale paralleling the railroad tracks(Herrera&Associates, Inc., 1997). Vegetation The dominant vegetation species within Herrera Wetland A were reported as Oregon ash(Fraxinus latifolia,FACW),red-osier dogwood(Cornus stolonifera, FACW) and reed canary-grass(Phalaris arundinacea,FACW)(Herrera&Associates, Inc., 1997). Based on a dominance of species rated Facultative or wetter,vegetation in the wetland is considered hydrophytic. Soils Soils in Herrera Wetland A were mapped as Woodinville loam by the NRCS (Snyder et al, 1973). The soils sampled in the wetland data plot were reported as dark gray(10YR 4/1)silt with dark yellowish brown(10YR 4/4)mottles from the surface to a depth of 16 inches(Herrera&Associates, Inc., 1997). These soils were considered hydric due to a low chroma soils(10YR 4/1 with mottles). Hydrology Herrera Wetland A hydrology was assumed through observation of indirect indicators of saturation within the wetland such as watermarks,drainage patterns, sediment deposits, and water stained leaves (Herrera&Associates,Inc., 1997). Classification and Rating According to the wetland classification system established by the USFWS(Cowardin et al, 1979),the Herrera Wetland A is classified as a palustrine scrub-shrub/palustrine emergent(PSS/PEM) wetland. This wetland would likely be classified as a Category 2 wetland by the City of Renton, because it is greater than 2,200 square feet and is not a Category 1 or 3 wetland(City of Renton, 1992). A large blackberry thicket dominates the southcentral portion of the site between Herrera Wetland A and Herrera Wetland B. Site topography and observed soil characteristics suggested that fill Draft Wetlands Study South 180th Street Grade Separation 19 April 1999 material was placed in the location of the Himalayan blackberry thicket, separating Herrera Wetland A from the larger Herrera Wetland B complex. Herrera&Associates speculated that a house with ornamental plants used to occupy this fill area, as evidenced by the presence of cherry trees, English ivy,red elderberry, and blackberries(Herrera&Associates, Inc., 1997). 5.6 Herrera Wetland B Herrera Wetland B is located in Renton and is part of a large wetland system that extends north beyond the study area,where it encompasses shrub/scrub,emergent and open water vegetation classes that are hydrologically connected to Springbrook Creek. The area of the wetland was estimated to be approximately 0.25 acre within the study area(Herrera&Associates,Inc., 1997). Vegetation The dominant vegetation species reported within Herrera Wetland B include Pacific willow(Salix lasiandra, FACW+),red-osier dogwood(Cornus stolonifera, FACW),invading Himalayan blackberry (Rubus discolor, FACU),hardhack(Spiraea douglasii, FACW) and reed canary-grass(Phalaris arundinacea,FACW)(Herrera&Associates, Inc., 1997). Based on a dominance of species rated Facultative or wetter,vegetation in the wetland is considered hydrophytic. Soils Soils in Herrera Wetland B were mapped as Woodinville loam by the NRCS(Snyder et al, 1973). The soils sampled in the wetland data plot were reported as very dark grayish brown UOYR 3/2) silt with dark yellowish brown(10YR 4/4)mottles from the surface to a depth of 16 inches(Herrera& Associates,Inc., 1997). These soils were considered hydric due to a low chroma soils with mottles. Hydrology Wetland hydrology within Herrera Wetland B was assumed through observation of indirect indicators of saturation such as with watermarks,drainage patterns, sediment deposits, and water stained leaves(Herrera&Associates,Inc., 1997). Classification and Rating According to the wetland classification system established by the USFWS(Cowardin et al, 1979),the Herrera Wetland B would be classified as a palustrine scrub-shrub/palustrine emergent(PSS/PEM) wetland. This wetland would likely be classified as a Category 2 wetland by the City Renton, because it is greater than 2,200 square feet and has minimum evidence of human related physical alteration(City of Renton, 1992). 6.0 WETLAND IMPACTS A total of 1.11 acre of wetland(all of Wetland A and Wetland C within the study area boundaries) will be filled and 2.29 acre of Wetland A buffer will be filled as a result of the development of four temporary detours,or"shooflies",for the BNSF and UPRR tracks. No impacts to wetlands are expected to occur as a result of the roadway and underpass construction. Impacts are shown on Figure 10. Prior to and during construction, Best Management Practices(BMP's)would be used to protect critical areas from development impacts.

These intrinsic features are complex, often inseparable, and difficult to assess and quantify. Evaluations of the functions of individual wetlands are necessarily qualitative and dependent upon professional judgment. A wetland functions and values assessment was conducted for impacted wetlands within the study area(Wetlands A and C)using the Wetland and Buffer Functions Semi-Quantitative Assessment Methodology, Draft User's Manual (Cooke, 1996). Using the Semi-quantitative Assessment Methodology(SAM),ratings were assessed for eight categories of wetland functions based on a number of variables that were evaluated for each category listed below. Functional assessment data forms are included in Appendix C. Flood/Storm Water Control Wetlands serve in flood/stormwater control through detention of peak flows within a wetland system and the slow discharge of the water to downstream receiving waters. The efficiency of a particular Draft Wetlands Study South 180th Street Grade Separation 22 April 1999 wetland system in performing runoff control is based upon the storage capacity and outlet discharge capacity of the wetland relative to the magnitude of the inflow. The value of wetlands in reducing downstream flooding increases with an increase in wetland area,the magnitude of the flood,the proximity of the wetland to the flooded area, and the lack of other storage areas. Base flowlGroundwater Support Functions Wetlands can recharge an aquifer, discharge to a downstream wetland, and/or attenuate surface water flows. Wetlands can provide groundwater recharge or discharge, or provide both, at different times of the year. The majority of wetlands serve predominantly for groundwater discharge and only a few are recharge systems. Groundwater recharge replenishes aquifers and filters water. With later discharge elsewhere(often in other wetlands),it provides a perennial water source for wetlands and provides dry season stream flow,benefiting stream dependent species. ErosionlShoreline Protection Functions Erosion control is closely linked with other wetland functions and is most often of concern in wetland systems with water flow sufficient to re-suspend and transport sediments, or in wetlands that have been physically disturbed. Decreased water velocity,vegetative structure, soil root-binding properties and substrate type will lessen the effect of water-related erosion. This function is especially present in shallow,flood plain wetlands where velocities are slow and vegetation is dense. Such vegetation is composed of species that provide for effective trapping of sediments, and which impede or slow water flow so that sediments settle out. Erosion and shoreline protection is especially important in riparian corridors where the vegetation can have strong root systems to hold sediments together and prevent loss of stream banks. This function is not present in isolated wetlands that do not have water flowing through them. Water Quality Improvement Functions The morphology of freshwater wetlands provides simple physical processes that remove sediment. Flood plain morphology,the length and width of the wetland,landscape characterization,vegetation community structure, and productivity have a great influence on the water velocity,type of sedimentation and rate of sedimentation. Particulate materials are removed through settling,which is controlled by water velocity,particle size, and the residence time of water in the wetland,through physical filtration by vegetation, and substrate. Wetlands remove excessive nutrients,heavy metals, and certain organic compounds through a variety of physical and biological processes. The ability of a wetland to perform these functions is closely related to other functions such as sediment removal,water quality parameters,wetland hydrology, and vegetation community composition, density,richness, structure, and productivity. The ability of a wetland to perform these functions varies with the nature of the wetland,the degree of disturbance of the wetland, and according to unusual events and seasonal cycles. Water quality parameters such as dissolved oxygen(DO),pH, and total suspended solids(TSS)influence the chemical form and fate of nutrients,metals, and organic compounds in wetland systems. Nutrients and other pollutants often bind with suspended sediments are incorporated into the soils through sedimentation. Nutrients,metals and organic materials stored in the soils are taken up by vegetation as biomass, buried in the sediments as peat is deposited, or exported out of the wetland. Natural Biological Support Functions Wetlands generally are characterized by high primary productivity(food production that fuels the food chain). Primary production within wetlands can be important to wildlife and fish that spend part or all of their lives within wetlands. There are two major energy flow patterns in wetlands: the Draft Wetlands Study South 180th Street Grade Separation 23 April 1999 grazing food chain which involves the consumption of living green plants, and the detrital food chain composed of organisms that depend on detritus and/or organic debris for their food source. Areas with surface flow have the potential to export decomposed photosynthetic products beyond the boundary of the wetland. Nutrient cycling in wetlands occurs in both plants and the sediments. Nutrients can be stored in sediments by being bound to organic compounds and clays. Nutrients that are incorporated into plant tissues are unavailable to the ecosystem as long as the plant material is alive. Annual growth in deciduous plants usually dies back at the end of the growing season, and the biomass ends up falling to the ground. The biomass either decomposes and releases the nutrients as dissolved compounds, or stays bound to organic matter in saturated conditions until conditions become conducive for decomposition. Once the nutrients are released,they become available for uptake by other plants, can be in storage in the sediments, and the cycle continues. Many species of wildlife are adapted to or require wetland habitats for at least a portion of their life cycle. The variety of vegetation, substrate types,hydrologic regimes, and the sizes and characteristics of the edge between habitat types are critical factors for wildlife. The association between adjacent habitats is especially important in riparian areas that are crucial to many species of wildlife. Overall Habitat Functions Plant species occur in distinct communities that are identifiable and often repeated across the landscape. Most species of both plant and wildlife have preferred habitats in specific zones associated with physical gradients such as light,moisture,hydrologic regime and elevation. High plant species richness is often associated with areas that have multiple habitats in close proximity. Mature wetland systems are characterized by the presence of many niches accounting for high plant and animal diversity. Rare, large or unusual habitats are valuable and are often set aside as sanctuaries. The rareness of a wetland community"type"may be due to the lack of a particular set of environmental factors,or species distributions in a particular watershed or region. The rarity of a wetland-associated species may be due to the fact that the species is adapted to a specific set of environmental conditions,which may not be present in very many places. The opportunity for the species to have appropriate conditions for living may therefore be rare. Wetlands may also be differentially lost and rare in a region because particular wetland types have experienced more development pressure or a re especially sensitive to human impacts. Specific Habitat Functions Invertebrate habitat. Wetlands near aquatic habitats can be considered to have aquatic invertebrates(insects), even if none are directly observed. Examples of invertebrate habitat are muddy shallow water areas where water velocities are slow,there is no fine sediment build-up, and thin-stemmed emergent plants such as sedges,rushes and some aquatic herbs are present. Amphibian habitat. Water depth is important,with individual species preferring specific depths. In general, shallow water zones with between 1 and 2.5 feet of water are ideal. Urbanized wetlands where bullfrogs are present are less likely to have a rich amphibian fauna due to their competition with native species. Fish Habitat. It is assumed that if a stream associated with a wetland has good gravels, permanent moving water, and overhanging vegetation along the banks of the stream is present to prevent water temperatures from getting too high,it has high fish habitat potential. If the same conditions exist but an obstruction over 15 feet long is present downstream,then the habitat potential is only moderate to low. Draft Wetlands Study South 180th Street Grade Separation 24 April 1999 Mammal Habitat. High habitat potential is where a large,very structurally diverse habitat is present within the wetland or adjacent buffer boundary that is at least 100-feet wide. The presence of houses and domesticated pets decreases the likelihood of the presence of native small mammals. Bird Habitat. High habitat potential is available in seasonally flooded agricultural fields, large structurally diverse wetlands, or lacustrine (lake or large pond) systems with associated wetland and buffer habitats. Cultural/Socioeconomic Functions Cultural and economic characteristics are evaluated from a purely value-based perspective. Most of the human-use opportunities can be quantified by determining the ownership of the wetland and associated buffer, and the proximity of the wetland to humans who could potentially use the wetland for recreational or commercial purposes. Not all wetlands provide all of the functions and values listed above. It should be noted that four wetlands within the study area extended beyond the study area boundaries and were not investigated beyond these boundaries. Functions and values discussed in this report represent only the portions of the wetlands within the study area. For ease of discussion purposes in this report,the numbered rating for each category has been converted to a high,moderate, or low rating as follows: ■ High= 75-100% of maximum score ■ Moderate= 50-74% of maximum score ■ Low = <50%of maximum score Based on these ratings, each wetland was given an overall low,moderate,or high rating. Wetland A functional values rated: ■ MODERATE for flood and storm water control; ■ MODERATE for base flow and groundwater support; ■ LOW for erosion and shoreline protection; ■ HIGH for water quality improvement; ■ MODERATE for natural biological support; ■ HIGH for overall habitat functions; ■ HIGH for specific habitat functions; and ■ MODERATE for cultural and socio-economic values. Wetland C functional values rated: ■ MODERATE for flood and storm water control; ■ MODERATE for base flow and groundwater support; ■ erosion and shoreline protection did not apply; ■ MODERATE for water quality improvement; ■ LOW for natural biological support; ■ LOW for overall habitat functions; ■ LOW for specific habitat functions; and ■ LOW for cultural and socio-economic values. Draft Wetlands Study South 180th Street Grade Separation 25 April 1999 8.0 REGULATORY FRAMEWORK 8.1 Wetland Regulation and Classification The primary federal laws that regulate activities in or near wetlands are Sections 401 and 404 of the Clean Water Act(CWA), and Section 10 of the Rivers and Harbors Act of 1899. Section 401 of the CWA mandates that federally permitted activities in wetlands comply with the CWA and state water quality standards. The Washington State Department of Ecology is responsible for administering the Section 401 regulations in the State of Washington. Under Section 404 of the CWA,the U.S. Army Corps of Engineers(Corps)has been given the responsibility and authority to regulate the discharge of dredged or fill materials into waters and adjacent wetlands of the United States(Federal Register, 1986). 8.2 City of Tukwila Wetland Regulations Wetland impacts are limited to the jurisdiction of the City of Tukwila,therefore only the city's regulatory requirements will be discussed. The City of Tukwila,through the adoption of the Sensitive Areas Overlay(Chapter 18.45,Tukwila Municipal Code)regulates development activities within and adjacent to wetlands and other sensitive areas. Regulated wetlands are defined as"those ponds or lakes 30 acres or less and those lands subject to the"wetland"definition..."in Section 2.1 of this study. Constructed wetlands are not considered wetlands. However, artificial wetlands intentionally created from nonwetland areas to mitigate wetland impacts as permitted by the City of Tukwila are considered wetlands. Isolated wetlands that are less than 1,000 square feet or smaller in area may not require compensatory mitigation (Chapter 18.06,Tukwila Municipal Code). The City of Tukwila classifies wetlands according to the system developed by the U.S. Fish and Wildlife Service(USFWS)(Cowardin et al, 1979). Wetlands are rated by the City of Tukwila according to three categories, as shown in Table 2. Table 2. City of Tukwila Sensitive Areas Overlay Wetlands Rating System Wetland Class Wetland Buffer Type 1 Wetlands: Those wetlands that meet any of the following criteria: a) The presence of species listed by the federal government or the State of 100 feet Washington as endangered or threatened,or the presence of critical or outstanding actual habitat for those species; b) Wetlands having 40 to 60 percent permanent open water in dispersed patches with two or more classes of vegetation; or c) Wetlands equal to or greater than 5 acres in size and having three or more wetland classes, one of which may be substituted by permanent open water. Type 2 Wetlands: Those that meet any of the following criteria: a) Wetlands greater than 1 acre in size; 50 feet b) Wetlands equal to or less than 1 acre in size and having three or more wetland classes; c) Wetlands equal to or less than 1 acre in size,that have a forested wetland class comprised of at least 20 percent coverage of the total surface area; d) The presence of heron rookeries or raptor nesting trees; or e) The presence of native plant associations of infrequent occurrence. Type 3 Wetlands: Those wetlands that are equal to or less than 1 acre in 25 feet size and that have two or fewer wetland classes. (Chapter 18.45.020.C., Tukwila Municipal Code, City of Tukwila, 1997) Draft Wetlands Study South 180th Street Grade Separation 26 April 1999 According to City of Tukwila classification,Wetland A would likely be classified as Type 2 wetland by the City of Tukwila,because it is estimated to be greater than 1 acre in size,is subject to disturbance, and has no critical habitat or threatened/endangered species. Type 2 wetlands require a 50-foot buffer. Wetland C would likely be classified as a Type 3 wetland because it equal to or less than 1 acre in size and has two or fewer wetland classes. Type 3 wetlands require a 25-foot buffer. A mitigation plan must be completed for any proposals for dredging,filling, alterations and relocation of wetland habitat allowed in TMC 18.45.080A, 080B and 080H. The mitigation plan is developed as part of a sensitive area study by a specialist approved by the Planning Director. Wetland an/or buffer alteration or relocation may be allowed only when a mitigation plan clearly demonstrates that the changes would be an improvement of wetland and buffer quantitative and qualitative functions. The plan must follow the performance standards of TMC Chapter 18.45 and show how water quality,wildlife and fish habitat, and general wetland quality would be improved. In order to achieve the City of Tukwila's goal of no net loss of wetland functions and acreage, alteration of wetlands require the applicant to provide a restoration, enhancement or creation plan to compensate for the wetland impacts at a ratio of 1.5 to 1 (area created:area impacted). On-site compensation is preferred, provided, except where the applicant can demonstrate that: ■ The hydrology and ecosystem of the original wetland and those who benefit from the hydrology and ecosystem will not be damaged by the on-site loss; and ■ On-site compensation is not scientifically feasible due to problems with hydrology, soils,waves or other factors; or ■ Compensation is not practical due to potentially adverse impact from surrounding land sues; or ■ Existing functional values at the site of the proposed restoration are significantly greater than lost wetland functional values; or ■ That established regional goals for flood storage,flood conveyance,habitat or other wetland functions have been established and strongly justify location of compensatory measures at another site. Off-site compensation must occur in the same watershed where the wetland loss occurred. In selecting compensation sites, applicants should pursue siting in the following order of preference: ■ Upland sites which were formerly wetlands ■ Idled upland sites generally having bare ground or vegetative cover consisting primarily of exotic species,weeds, or emergent vegetation ■ Other disturbed upland Wetland enhancement or other mitigation landscaping is a permitted use in sensitive areas or buffers only after review and approval by the Planning Director. Artificial wetlands intentionally created from nonwetland areas to mitigate conversion of wetlands as permitted by the City of Tukwila shall be considered wetlands. Baseline information of quantitative data collection or a review and synthesis of existing data is required for the proposed mitigation site. Draft Wetlands Study South 180th Street Grade Separation 27 April 1999 9.0 MITIGATION GOALS AND OBJECTIVES According to the Tukwila Municipal Code,mitigation for impacts to wetlands must be considered in the following order: ■ avoid disturbance to wetlands, streams and/or buffers; ■ minimize impacts to wetlands, streams and/or buffers; ■ compensate for any wetland, stream or buffer impacts; ■ restore any wetlands, streams or buffers impacted; and ■ create new wetlands and buffers to replace those that were lost. For this project,the project design team considered all practical efforts to avoid and minimize potential impacts that could occur to wetlands and streams. Impacts to Wetlands B, D, and Herrera A and B and their associated wetland buffers will be entirely avoided. Mitigation measures will rely on wetland creation along with buffer enhancement as compensation for impacts to Wetlands A and C. A minimum of 1.67 acres of wetland replacement is required. Wetland mitigation goals for the project are as follows: ■ To achieve no net on-site loss of wetland and wetland buffer functions and values within the Springbrook Creek drainage basin ■ To compensate for loss of Wetland C and the filled portions of Wetland A ■ To avoid habitat fragmentation The objective of the mitigation plan developed for the project would be to create a mitigation wetland with several habitat types to compensate for the lost functions and values of Wetland C and the filled portions of Wetland A and its buffer that provide connectivity to existing habitat corridors. The created wetland would be consistent with mitigation requirements as stated in the Tukwila Municipal Code by providing a minimum of a 1.5 to 1 replacement ratio for wetland areas. Based upon the existing functions of the wetlands and wetland buffers to be filled,the created mitigation wetland area would provide at a minimum a net gain in the following functional wetland ratings to the following levels: ■ HIGH for flood and storm water control; ■ HIGH for base flow and groundwater support; ■ MODERATE for erosion and shoreline protection; ■ HIGH for water quality improvement; ■ HIGH for natural biological support; ■ HIGH for overall habitat functions; ■ HIGH for specific habitat functions; and ■ HIGH for cultural and socio-economic values. 10.0 WETLAND MITIGATION ALTERNATIVES ANALYSIS The above stated goals and objectives for on-site mitigation would be accomplished by creating a palustrine emergent and palustrine scrub-shrub wetland with an open water component. In order to guide the City's mitigation efforts,several wetland creation and enhancement options were investigated and are discussed below. Draft Wetlands Study South 180th Street Grade Separation 28 April 1999 10.1 Wetland Creation and Restoration Site Selection Criteria The criteria for selecting wetland creation and restoration areas included the following considerations: ■ A preference for sites located within the same drainage sub-basin ■ Sites located within areas with sufficient hydrology to support wetland vegetation and seasonal amphibian habitat ■ The potential for connectivity to existing habitat corridors Ideally,the mitigation wetlands would be situated so that they form a continuum with adjacent and nearby habitat corridors which can result in a combined net gain in wildlife habitat function for all associated systems. 10.2 Potential Wetland Creation Site Alternatives Three potential wetland mitigation sites were investigated and are discussed below. Herrera Wetlands Site As previously described,the Herrera Wetlands site is a parcel located within the City of Renton east of the BNSF and north of South 180th Street(Figure 11). The estimated available upland area for mitigation at this site is 2.15 acres. The potential wetland creation area includes the upland area surrounding the wetlands and dominated by a large blackberry thicket. Site topography and observed soil characteristics suggest that fill material was placed in the location of the expansive Himalayan blackberry thicket, separating Herrera Wetland A from the larger Herrera Wetland B complex. This upland area may have historically been part of a larger wetland area prior to historic residential development. Historic aerial photography analysis could provide insight into the nature of the impacts to the site and historic site-specific wetland conditions prior to site development. Fill materials can potentially be removed exposing original hydric soils and restoring historic wetland hydrology. Given the current dominance of blackberry throughout this area, significant improvement in vegetation community structure and diversity is achievable. Significant improvement in wildlife habitat can also be achieved with connectivity to existing study area wetlands and the Springbrook riparian corridor. The site is within the jurisdiction of the City of Renton,therefore, an agreement would need to be established between the City of Tukwila and the City of Renton for use of the site. Mill Creek Upland Site The Mill Creek upland site is a"landlocked"parcel positioned south and east of Mill Creek and immediately east of the BNSF right-of-way within the City of Kent(Figure 12). The parcel comprises approximately 8.4 acres. The parcel is bordered by a warehouse facility on the east and the newly constructed Creekside Storage facility across Mill Creek on the north. Permission to access the site to complete a habitat and sensitive areas reconnaissance level analysis has not been secured to date. Observations were completed from adjoining areas accessible to the general public and from aerial photography. The soil series mapped on the site by the NRCS is Woodinville silt loam, a hydric soil.

The eastern half appears to be comprised generally of a mixed scrub-shrub community with both forested and open grass patches throughout this portion of the property. Observable dominant tree species included cottonwood and red alder,which suggests the potential for development of on-site wetlands. Topographically,the parcel is positioned approximately 20-feet above the elevation of Mill Creek and its associated riparian wetlands. The potential wetland creation area is located in what appears to be an upland area dominated by a large blackberry thicket in the western portion of the site east of the railroad tracks. Prior to consideration of this site for wetland creation, subsurface hydrologic characteristics would need to be documented and groundwater elevations determined through a wetland reconnaissance of the property during the growing season. Given the current dominance of blackberry throughout this area, significant improvement in vegetation community structure and diversity is achievable. Significant improvement in wildlife habitat can also be achieved that can be linked directly to the greater Mill Creek/Springbrook Creek riparian habitat corridor. This parcel is located within the City of Kent,therefore,purchase of the property by the City of Tukwila or an agreement between the two cities would need to be established for development of the parcel as a wetland mitigation site. City of Tukwila Wetland WL12 Mitigation Site The Wetland 12 site is located to the north of South 180th Street and west of the UPRR tracks and the Interurban Trail(Figure 13). An existing mitigation area is located on the south side of this wetland immediately beyond the study area boundary on a privately owned parcel. A portion of this area is currently undeveloped and may be available for wetland creation immediately adjacent to the existing wetland mitigation area. A determination of the acreage available for mitigation would need to be determined through site reconnaissance with permission from the property owner. Visual observation of the existing mitigation area from the Interurban Trail suggests that sufficient subsurface hydrology may be present to expand the existing wetland area within the parcel. Significant increase in wetland functions could be achieved by introducing shrub-scrub and forested vegetation community structure into the existing mitigation area that is consistent with other vegetation community patches within Wetland 12. Improvement in wildlife habitat can also be achieved that can be linked to the existing wetland and to the wetlands on the east side of the Interurban Trail. One benefit of utilizing this site is that compensatory mitigation for the impacted portions of Wetland A and Wetland C could potentially be achieved within the City of Tukwila's jurisdictional boundary. 11.0 CONCEPTUAL WETLAND CREATION PLANTING PLAN The most desirable option for wetland mitigation is creation of one large wetland rather than several small isolated wetlands. Ideally,the created wetland would incorporate at least one shallow, seasonal open water feature which can provide seasonal amphibian breeding and rearing habitat, and at least two vegetation classes such as a herb and scrub-shrub layer. A mosaic of created vegetative communities would result in a net increase in wetland functions over their current levels, and may increase the cumulative functional value of the adjacent sensitive areas due to the greater diversity of vegetation and habitat structure. A detailed wetland mitigation and planting plan would be developed once the preferred wetland mitigation site is selected.

Not to Scale North Source: City of Tukwila Wetland WL12 BERGER/ABAM Engineers 1999 South 180th Street Grade Separation Figure 13 If the wetland is created adjacent to or in close proximity to other wetlands and/or the stream corridor, wildlife habitat fragmentation would be avoided and maintenance and monitoring programs would be more efficient and cost effective. Within the created and wetland and buffer areas, shrubs and trees would be planted in groups designed to duplicate and supplement the plant communities in the existing wetland areas to be filled and,if applicable,in the adjacent wetland areas. Planting in the wetland creation area would be done by hand or using small mechanized equipment that would not compact soils. Within the created wetland, a variety of native tree, shrub, and emergent species will be planted at appropriate elevations with respect to seasonal water levels. Plant species to be used in all mitigation would be commercially available from local sources and native to the Puget Sound region. The created wetland would, at a minimum,be a Type 2 wetland, and would have a 50-foot buffer as required by the City of Tukwila. 12.0 LINIITATIONS Within the limitations of schedule,budget, and scope-of-work,BERGER/ABAM warrants that this study was conducted in accordance with generally accepted environmental science practices, including the technical guidelines and criteria in effect at the time this study was performed, as outlined in the Methodology section.

From: Robin Tischmak Date: October 9, 2000 Subject: S 180 St Grade Separation Preliminary (60%) P.S. & E. Review Berger/Abam has submitted preliminary (60%) plans for design of a grade separated intersection of S 180 St (SW 43 St) and the UPRR and BNSFRR rail crossings. The project will impact the street, surface water, water & sewer (both Renton's), and several other disciplines. Attached are the plans for review. A construction estimate will be distributed after I receive it in the next few days. A meeting to discuss comments is scheduled for 9:00 a.m. on Thursday, October, 1 9th in Conference Room 1. Please take some time to review the project and note any comments for discussion at the meeting. Please call me at (206) 433-0179 if you should have any questions.
