April 20, 2004 King County Daryl Grigsby, Division Director Water and Land Resources Division Department of Natural Resources, :. 201 South Jackson Street, Suite 600 Seattle, Washington 98104-3855 Dear Mr. Grigsby; RE-- 2004 Riparian Planting Temporary Water Use Request According to RCW 90.54.020(3), the quality of the natural environment shall be protected, and where possible, enhanced. Withdrawals of water which would conflict therewith shall be authorized only in those situations where it is clear that overriding considerations of the public interest will be served: This letter is in response to your request, dated April 14, 2004, for authorization to use surface waters for the King County's Water and Land Resources Division (WLRD) vegetation watering of the 2004 project sites. The Department of Ecology (Ecology) is committed to supporting projects such as these, which will have a direct positive impact on the streams and stream habitat in King County. Ecology appreciates the cooperation you have shown in seeking alternative methods to watering the 2004 project plants when instream flows are not. being met or, when a water body has been closed to further appropriation. In watersheds where instream flows or closures have been established, any water rights subsequently issued-bv t-cology.-ai•e conditioned tie instream flows. This means the right to use water can legally be interrupted if stream flow drops below a specific point. It is Lip to 'the applicant to check ttie gages in the sources indicated as subject to low flows and be responsible for the termination of watering when the flows are not being met. Therefore, you should consider this letter authorization to appropriate water, subject to provisions as listed by project. The duration of water use is authorized from the date of this letter through September 30, 2004. The Water and Land Resources Division is to keep record of how much water is being used at each site during each watering. Each project site should use procedures to eliminate any waste of water. The Water and Land Resources Divisionwill'notify Ecology if any of these projects have ended prematurely, been delayed; or completed. This Authorization may be appealed pursuant to chapter 43.21 RCW. The person to who this Authorization is issued must file an appeal with the Pollution Control Hearing Board within thirty (30) days of receipt of this Authorization. Send the appeal to "Pollution Control Hearings Board, P.O. Box 40903, Olympia, Washington 98504-0903." At the same time, a copy of the appeal must be send to: Department of Ecology, Water Resources, Appeals Coordinator, P.O. Box 47600, Olympia, Washington 98504-7600. -All others receiving notice of this Authorization must file an appeal with the Pollution'Control Hearings Board within thirty (30) days of the date the Authorization was mailed in the same manner described above. An appeal alone will not the stay the effecti:veness`of the Authorization. Stay requests must be submitted in accordance with RCW 43.21B.320. Sincerely, Daniel L.

This year, we are requesting surface water withdrawals from 16 restoration sites. All of the 2004 projects are first -year plantings or subsequent•.phases :of multi -year restoration efforts. One project will be watered using reclaimed water the Renton Wastewater Treatment Plant. Enclosedois a list of this year's projects. WLRD is committed to replanting native vegetation along streambanks and shorelines to promote bank stability and.to restore and enhance fish and wildlife habitat. Projects are drainage and habitat improvement projects, habitat restoration projects, and volunteer planting projects. They include streambank stabilization using bioengineering techniques, riparian buffer creation, road and culvert removal, and installation of instream habitat and sediment contra] structures. Goals include repairing the natural functions of buffers, restoring riparian habitat complexity,. enhancing instream habitat, improving water quality by reducing erosion, increasing shade to maintain cool water temperatures, and providing a future source of woody debris •for streams. This letter requests permission to use water from rivers, streams, and lakes adjacent to the listed revegetation sites to help maintain and establish plants during their first and second summers.. Water would be used from, streams ,only if,the stream conveys, at ,least, one cubic foot per second (449;gallons.per. minute) during summer1-1;1ibaseflgw . I.Water;will not be withdrawn if any of the associated water bodies: fall below an established minimum instream flow. Water would be withdrawn, as deeded, using either buckets or a portable, lightweight pump, and the maximum watering duration for each site would be once per week, from May through September.

This is not normal practice with FHWA. As such, we needed to receive blessing from Jim Leonard (FHWA's environmental lead for 1-405) . Jim has given his blessing; however, his blessing comes with strings. Jim's concern is to avoid communicating draft findings in any public forum. Please review Jim's "strings" to see if the City can work with them. I've attached a timeline that we think the DRs will arrive to the City. The review period will be 10 workings days. The City's review will be limited to the June 2005 Scoping Report. I had staff review the scoping report to identify all of the DRs that were referenced. These DRs are noted in the attached schedule. Note: Many comments for "North Renton" scoping were related to wells/parks concerns. These project elements are moved to the "South Renton Implementation Plan" NEPA document. Review Conditions: 1. The DRs will be clearly marked as 'draft.' 2. City will review only those DRs that contain topics that the City commented on during the scoping period (note: wells/parks comments will be moved to the South Renton Implementation Plan NEPA). The 1-405 team will provide a copy of all the City's scoping comments, and will note which comments no longer apply to the R213 project. The goal of the review will be for City staff to ensure that scoping comments have been adequately addressed. 3. The review period for each DR will be 10 working days. 4. City staff will not communicate any of the draft DR findings to the public. 5. If City staff needs to brief Council, then briefings will be done in a non-public forum. Dialogue will be clearly communicated as 'draft conclusions.' 6. City staff will provide one list of consolidated comments for each DR to the 1-405 team on an electronic spreadsheet (to be provided by the 1-405 team). Please let me know if the City can limit the review to these conditions. Thanks, Stacy.

Johns Creek Background The City of Renton and WSDOT have jointly investigated a non-traditional proposal to provide water quality treatment and stormwater controls for runoff from the I-405 Corridor Project from MP 4.59 to MP 6.09. Water quality treatment will be provided for all runoff from the I-405 right-of-way, which will include 7.3 acres of new impervious area from the I-405 improvements in the Johns Creek watershed. The Johns Creek watershed is 1082 acres. Upstream of I-405, the watershed includes 868 acres of primarily residential land use. I-405, including the new impervious area, occupies 72.6 acres. The watershed downstream of I-405 is primarily commercial land use and includes 215 acres of land (including the I-405 area). The increased impervious area from expansion of I-405 would increase impervious area within the basin by less than 1%. All water within the basin currently drains to Johns Creek, and this water is currently discharged near the entrance to Gene Coulon Memorial Beach Park. Under existing conditions, runoff from this part of I-405 is combined with runoff from the upper Johns Creek watershed (City of Renton, residential area), and then discharged to the City of Renton drainage system located in the lower basin. The City storm system routes the runoff westerly along N 8`h to where it joins the North 8ch Street/Garden Avenue North storm system. The Garden Avenue North storm system then conveys the water north to where it discharges to a series of intermittent stream and culvert conveyances on Johns Creek beginning approximately 200 yards upstream of the entrance road to Gene Coulon Memorial Beach Park. —Greg Zimmerman April 25, 2005 Page 2 A traditional stormwater response for this watershed would construct a series of stormwater vaults within the existing WSDOT Right of Way (ROW) to provide both water quality treatment and flow control, as required by the WSDOT Highway Runoff Manual. The City of Renton and WSDOT held a series of discussions in 2004 and early 2005 to develop a more efficient and cost-effective solution to managing stormwater within the Johns Creek basin. 15% Design Development The City of Renton and the I-405 team held a series of discussions to develop the proposed Johns Creek Outfall as the stormwater component of the North 8Ih Street HOV Direct Access Project. This design concept was investigated sufficient to allow preparation of a 15% design package. The design addresses a series of potential concerns and opportunities that were identified through the discussions. Protection of Gene Coulon Memorial Beach Park facilities and plant materials was identified as a major concern, which triggered additional study, consideration of several discharge locations, and careful routing of the discharge pipe to minimize disturbance to Park facilities. Minimizing disruption to Park operations and the Parks users was also a major concern and resulted in limitations on construction timing and activities. Sizing the new stormwater facilities to handle anticipated future flows from both I-405 and from residential areas in the upper watershed was also addressed during preliminary design. Finally, minimizing impacts to the backwater channel of Johns Creek was also a major concern which triggered studies of the projected changes to water surface elevation and stream flow velocities. Preliminary design discussions identified the opportunity to forgo stormwater detention (flow control) for this project. The purpose of stormwater detention is to provide protection to downstream areas from erosion and flooding problems associated with increased flows as a result of a project. Studies as part of preliminary design established that detention would not provide any meaningful additional protection to downstream areas, and detention would not serve a useful purpose for this project. The bulk of the downstream conveyance for this project will be drainage pipes specifically sized and constructed to convey both current and anticipate future flows. This piped system has been sized specifically for the projected future flows and will not be affected by either erosion or flooding issues. A short section of Johns Creek within Gene Coulon Memorial Beach Park that would receive the additional discharge was investigated during preliminary design. Studies established that this is a backwater channel of Lake Washington, and the channel is sufficiently large that neither water elevation nor flow rate will be noticeably changed by the project's peak discharges. To address concerns identified during the preliminary design process, a series of conditions were developed which state the specific concerns and how they will be addressed during final design and construction. A full listing of the conditions, which will guide final design and construction, is attached (Johns Creek Outfall Attachment 1) Amk Washington State Page 2 T�Department of Transportation —Greg Zimmerman April 25, 2005 Page 3 Final Design Development The City of Renton and WSDOT anticipate continuation of the cooperative design process during the development of Final Design for this project. Development of the final design will be guided by the conditions established during the preliminary design process and described in the attached Johns Creek Outfall Attachment 1. Funding for the final design and construction of the North Renton Congestion Relief and Bus Rapid Transit Project is dependent on future funding actions, such as legislative action by the State of Washington or a Regional Transportation Investment District (RTID) public vote. Concurrence I am anticipating a project that will set a high standard of cooperation between the City of Renton and WSDOT. I ask, by signing below, that the City and WSDOT concur with the 15% design for the Johns Creek Outfall. This 15% design will be examined by the project's NEPA and ESA documents, which are currently in preparation. The City and WSDOT commit to work together, guided by the conditions in the attached Johns Creek Outfall Attachment 1, to develop the final design, obtain necessary approvals, and prepare associated permits once funding becomes available.

Included in this outline is a listing of the responsibilities of each party as part of the anticipated agreement, and the 15% design for the Johns Creek Outfall and related conveyance systems (Appendix E: Johns Creek Backwater Analysis and Appendix F: Outfall Pipeline Hydraulic Analysis, Supplements to Preliminary Hydraulic Report, North 81h HOV Direct Access). Both parties are aware that the Johns Creek Outfall is a part of the larger Renton to Bellevue Project and that funding for the Renton to Bellevue Project has not been allocated at the time this document was prepared. Both parties presume that funding will occur in the foreseeable future and they wish to complete this letter of concurrence now to provide the certainty that the Johns Creek Outfall and the associated flow exemption will be included as designed in the Renton to Bellevue Project once funding is secured and construction commences. Both parties agree: the Park needs to tie profected'during'constuction ♦ That Gene Coulon Memorial Beach Park is an important recreational resource to the City of Renton, and that substantial efforts should be made during construction of the Johns Creek Outfall to minimize disruption of Park uses; and the Johns Creek Backwater Study is�accuratd ♦ That the Johns Creek Backwater Study based upon the 15% design work accurately describes the existing condition of the local drainage system in the vicinity of Gene Coulon Memorial Beach Park at the time of this agreement, and accurately anticipates the effects of Johns Creek Outfall on the local drainage systems in the Johns Creek watershed.

Zimmerman: This letter documents that the City of Renton and the Washington State Department of Transportation (WSDOT) concur with the 15% design for the Johns Creek Outfall. Johns Creek Background The City of Renton and WSDOT have jointly investigated a non-traditional proposal to provide water quality treatment and stormwater controls for runoff from the I-405 Corridor Project from MP 4.59 to MP 6.09. Water quality treatment will be provided for all runoff from the I-405 right-of-way, which will include- 7.3 acres of new impervious area from the area that would be adde a to I-405 improvements in the Johns Creek watershed. The Johns Creek watershed is 10820K acres. Upstream of I-405, the watershed includes 868 acres of primarilywhie is large y composed of residential land use. (868-aeres) - camm}e-.-a!(215 acres), land uses. I-405, including the new impervious area, occupies 6-572.6 acres. The watershed downstream of 1-405 is primarily commercial land use and includes 215 acres of land (including the I-405 area). within the johns -Qeek Watershed. The increased impervious area from expansion of 1-405 would increase impervious area within the basin by less than 1 %. All water within the basin currently drains to Johns Creek, and this water is currently discharged near the entrance to Gene Coulon Memorial Beach Park. Under existing conditions, runoff from this part of I-405 is combined with runoff 'from the upper Johns Creek watershed (City of Renton, residential area), and then discharged to the City of Renton drainage system located in the lower basin. The City storm system routes the runoff westerly along N 8th to where it joins the North 8th Street/Garden Avenue North storm system. The Garden Avenue North storm system then conveys the water north to where it discharges to a series of intermittent stream and culvert MayofKathy Keolker _ Whee e+ reg Zimmerman ATEW D ^ T'April 25, 2005 Page 2 conveyances on Johns Creek beginning approximately 200 yards upstream of the entrance road to Gene Coulon Memorial Beach Park. A traditional stormwater response for this watershed would construct a series of stormwater vaults within the existing WSDOT Right of Way (ROW) to provide both water quality treatment and flow control, as required by the WSDOT Highway Runoff Manual. The City of Renton and WSDOT held a series of discussions in 2004 and early 2005 to develop a more efficient and cost-effective solution to managing stormwater within the Johns Creek basin. 15% Design Development The City of Renton and the I-405 team held a series of discussions to develop the proposed Johns Creek Outfall as the stormwater component of the North 8`h Street HOV Direct Access Project. This design concept was investigated sufficient to allow preparation of a 15% design package. The design addresses a series of potential concerns and opportunities that were identified through the discussions. Protection of Gene Coulon Memorial Beach Park facilities and plant materials was identified as a major concern, which triggered additional study, consideration of several discharge locations, and careful routing of the discharge pipe to minimize disturbance to Park facilities. Minimizing disruption to Park operations and the Parks users was also a major concern and resulted in limitations on construction timing and activities. Sizing the new stormwater facilities to handle anticipated future flows from both I-405 and from residential areas in the upper watershed was also addressed during preliminary design. Finally, minimizing impacts to the backwater channel of Johns Creek was also a major concern which triggered studies of the projected changes to water surface elevation and stream flow velocities. Preliminary design discussions identified the opportunity to forgo stormwater detention (flow control) for this project. The purpose of stormwater detention is to provide protection to downstream areas from erosion and flooding problems associated with increased flows as a result of a project. Studies as part of preliminary design established that detention would not provide any meaningful additional protection to downstream areas, and detention would not serve a useful purpose for this project. The bulk of the downstream conveyance for this project will be drainage pipes specifically sized and constructed to convey both current and anticipate future flows. This piped system has been sized specifically for the projected future flows and will not be affected by either erosion or flooding issues. A short section of Johns Creek within Gene Coulon Memorial Beach Park that would receive the additional discharge ,.euk ���—�� was investigated during preliminary design. Studies established that this is a backwater channel of Lake Washington, and the channel is sufficiently large that neither water elevation nor flow rate will be noticeably changed by the project's peak discharges. To address concerns identified during the preliminary design process, a series of conditions were developed which state the specific concerns and how they will be ...I► Page 2 Washington Stale V0- Department of Transportation Mayef Kathy Keolker __Wheeler reg Timmerman NEA D n T April 25, 2005 Page 3 addressed during final design and construction.

The Garden Avenue North stonnPaf k Stfeet system then conveys the water north to where it discharges to a series of intermittent stream and culvert conveyances on Johns Creek beginning G ege "':ri,.r,,..m , Mayor Kathy Keolker - Wheeler b..

A traditional stormwater response for this watershed would construct a series of stormwater vaults within the existing WSDOT Right of Way (ROW) to provide both water quality treatment and flow control, as required by the WSDOT Highway Runoff Manual. The City of Renton and WSDOT held a series of discussions in 2004 and early 2005 to develop a more efficient and cost-effective solution to managing stormwater within the Johns Creek basin. 15% Design Development The City of Renton and the I-405 team held a series of discussions to develop the proposed Johns Creek Outfall as the stormwater component of the North 8th Street HOV Direct Access Project. This design concept was investigated sufficient to allow preparation of a 15% design package. The design addresses a series of potential concerns and opportunities that were identified through the discussions. Protection of Gene Coulon Memorial Beach Park facilities and plant materials was identified as a major concern. which triggered additional study, consideration of several discharge locations, and careful routing of the discharge pipe to minimize disturbance to Park facilities. Minimizing disruption to Park operations and the Parks users was also a major concern and resulted in limitations on construction timing and activities. Sizing the new stormwater facilities to handle anticipated future flows from both I-405 and from residential areas in the upper watershed was also addressed during preliminary design. Finally, minimizing impacts to the backwater channel of Johns Creek was also a major concern which triggered studies of the projected changes to water surface elevation and stream flow velocities. Preliminary design discussions identified the opportunity to forgo stormwater detention (flow control) for this project. The purpose of stormwater detention is to provide protection to downstream areas from erosion and flooding problems associated with increased flows as a result of a project. Studies as part of preliminary design established that detention would not provide any meaningful additional protection to downstream areas, and detention would not serve a useful purpose for this project. The bulk of the downstream conveyance for this project will be drainage pipes specifically sized and constructed to conveyho44 both current and anticipate future flows. This piped system has been sized specifically for the projected future flows and _will not be affected by either erosion or flooding issues. A short section of Johns Creek within Gene Coulon Memorial Beach Park could potentially be affected and was investigated during preliminary design. Studies established that this is a backwater channel of Lake Washington, and the channel is sufficiently large that neither water elevation nor flow rate will be noticeably changed by the project's peak discharges. To address concerns identified during the preliminary design process, a series of conditions were developed which state the specific concerns and how they will be r.rnc;i� Q.

This change is a reduction from two primary access routes to one. Currently, there are two secondary access routes to Renton Hill to be used by Police and Fire when the primary access is not available. These secondary access routes are also used for routine and special circumstances related to providing City services to the residents of Renton Hill in the most efficient manner. Method: Renton Fire apparatus were used to drive both the current primary and current secondary access routes to Renton Hill from Station 11 and Station 13. Response times for aid cars, engines and truck companies were measured. Times were measured using stopwatches and the Department's existing method for calculating emergency response. State Law and Department policy do not allow code red response for non -emergency situations. The times for the proposed Narco access were estimated based on known information on the grade of the access route and the distance as calculated by the City of Renton Transportation division. Emergency Response Criteria: Renton Fire Department emergency response criteria are as follows: 1. All code red call response is six minutes from the time of dispatch to the time of arrival at the address requesting service. The goal is four minutes or less. All responses over six minutes are evaluated to determine what the mitigating factors were. These may include subsequent calls, time of day and traffic, response vehicle location at the time of call. 2. For full first alarm response to larger emergencies such as house fires, the goal is 8 minutes for all first alarm units. This include three engines, one truck company, one aid car and one command vehicle. 3. Times were measure from each station to the intersection of 7`" and Renton Avenue. This intersection was chosen due to its location at the center of Renton Hill and at close to the highest grade on Renton Hill. These times were taken during the mid -week morning hours. Traffic was light, the weather was clear and the streets were dry. These are considered optimal conditions by the Renton Fire Department. Based on the traffic and weather during the data collection period and analysis of calls to Renton Hill for the period of 2001 thru 2003, a 10% response time increase was added to the times recorded. Results: Aid Car Engine Ladder Engine Sta.11 Sta.11 Sta.11 Sta.13 Mill Access 2:56 3:14 4:02 7:46 4tn Avenue 3:27 3:58 4:41 7:22 Grant * 7:19 7:28 8:14 6:25 Beacon * 8:24 8:46 10:11 7:17 Narco** 4:00 4:16 5:23 8:49 * The gates currently in place at Beacon and Grant were opened prior to the measuring of response times to simulate the presence opticom gates at these locations. * * The response times of the proposed Narco access were arrived at by calculating the distance and grade and measuring actual emergency vehicle response for similar distance and grade. This time was then added to the time to the base of the Mill access and the time from the intersection of Renton and Mill Ave to the intersection of 7ch and Renton Avenue. Analysis: A single primary access to Renton Hill proposed by WSDOT does not significantly impact emergency vehicle response times to Renton Hill. However, if this primary access is blocked or is in anyway unavailable, the secondary access at Grant Avenue or Beacon Way must be utilized. Based on data using these secondary response routes, response times are significantly longer than what the Fire Department allows. Station 11 units take, on average, an additional 4 minutes to respond to Renton Hill using the existing secondary access at Grant Avenue. These response times are longer than Renton Fire Department guidelines allow. The data shows that emergency response from Station 11 using the proposed Narco access is approximately 3 minutes faster than using the Grant Avenue access. This secondary access option is preferred by the Fire Department for access to Renton Hill by the primary responding Fire Station, which is Station 11. The secondary accesses off Beacon Way and Grant Avenue are both needed to properly serve Renton Hill and the multi -family housing accessed off Grant Avenue regardless of what the final configuration of I-405 and the primary access from downtown Renton are. Renton Fire Department continues to support three secondary access routes to Renton Hill if a single primary access route is constructed.

The Task Force's recommendation has been reviewed by the Design Team and is being forwarded to the Administrators Executive Committee for their concurrence and action. As the City of Renton and Washington State Department of Transportation (WSDOT) work together to plan and design the I-405 Corridor projects in Renton, issues arise that require focused effort and cooperation. The design issues at the I-405/SR 169 interchange is an example of some of the complicated issues we will be solving together throughout the life of the project. At this time, it appears that any design alternative will affect the City's drinking water facilities and parks in some way. The Task Force's Recommendation 91 established the I-405 footprint in the vicinity of the Parks and water supply facilities. The Recommendation also documented that there are many outstanding issues for the Task Force to resolve. The Task Force recommends that WSDOT submit to the City two commitment letters that demonstrate WSDOT is committed to work with the City to minimize impacts as much as possible and to address impacts through mitigation. One letter shall be for drinking water facilities and one letter for park facilities. The I-405/SR 169 interchange is immediately adjacent to Renton's Cedar River Park, Carco Park, Liberty Park and the City's new Henry Moses pool. City of Renton takes prides in its parks and is committed to protecting and promoting their park system. WSDOT shall submit a letter to the City demonstrating that WSDOT understands the importance of these parks and facilities, and that WSDOT will work closely with the City to identify, evaluate and implement appropriate and effective mitigation. The I-405/SR 169 interchange is immediately adjacent to facilities critical to the City's drinking water supply. This water supply, from the Cedar River Sole Source Aquifer, supplies more than 90 percent of the City's potable water. The Task Force's Recommendation #1 established the I- 405 footprint in the vicinity of the water supply facilities. This footprint identified the need to Jay Covington, Chief Administrative Officer City of Renton Page 2 September 29, 2004 relocate the Corrosion Control Treatment Facility (CCTF) building. WSDOT shall submit a letter to the City demonstrating that WSDOT understands the importance of the CCTF building, and that WSDOT will work closely with the City to identify, evaluate and implement appropriate and effective mitigation. Thank you for this opportunity to present the Wells/Parks Task Force WSDOT Commitment Letters Recommendation. I am asking for the Administrators Executive Committee's concurrence with the Task Force's recommendation. WSDOT and the City are committed to a continued partnership to find agreeable solutions for mutual benefit to the I-405 Project, Sole Source Aquifer and City Parks. Sincerely, Stacy C. Trussler, P.E.

In particular, WSDOT is committed to addressing the preliminary design of the water corrosion control treatment facility (CCTF) in advance of issuing the I-405 North Renton NEPA Environmental Assessment. As you know, the City of Renton and WSDOT have been in discussions regarding the I-405 Project impacts on the Cedar River Park and the City's wells and water treatment facilities. WSDOT is aware that the City has two wells at this location, including its most productive well, and two water treatment facilities, one for fluoride and one for corrosion. While all of these facilities are critical to the City's water supply, some impacts are unavoidable, and the Wells/Parks Task Force has identified a ramp alignment that has the least impacts. This solution was put forth to the Executive/Administrators Committee as Recommendation #1. The Executive/Administrators Committee approved this solution on July 23, 2004. With this solution, neither of the wells nor the fluoride treatment facility are directly impacted, but the CCTF is impacted and will need to be moved. WSDOT understands that this CCTF is critical for the City to provide Renton residents with drinking water that meets state and federal standards. Consequently, WSDOT is committed to working with the City to address in a timely manner any issues surrounding moving the CCTF and other water -related issues. As such, WSDOT understands that moving the corrosion treatment.facility requires advance approvals and permits from the Department of Health. The City's recent experience demonstrates that the approval process is complicated and could take several years. Consequently, WSDOT assures the City that WSDOT will demonstrate that the design of the CCTF will be permitable and buildable. The reconstruction of the treatment facility will need to occur before the existing CCTF is taken off-line. WSDOT commits that the new CUT building will be appropriately designed, constructed, and tested in advance of decommissioning the Gregg Zimmerman, Public Works Director City of Renton Page 2 September 29, 2004 existing CCTF. Further, once regional project funds are available to construct the project, WSDOT commits to re -assess the CCTF building design and permit requirements, and WSDOT will update and complete the design as appropriate. WSDOT is committed to working with the City to address these issues sufficiently before issuing the NEPA EA. The I-405 Project Team members include not only engineers, but also professional staff with expertise in water treatment design and permitting, hydrogeology, and utility relocation. Specifically, water treatment engineers with knowledge of the City's CCTF are readily available. As we evaluate the CCTF relocation, we will utilize their expertise. Addressing these specific design solutions is an important part of the project, and WSDOT recognizes the role water treatment engineers have in developing and determining solutions to the issues surrounding relocating the CCTF near this interchange. WSDOT appreciates this opportunity to work with the City of Renton and to clarify its commitment to resolving the issues surrounding the corrosion treatment facility. As with any project the size and complexity of the I-405 Project, many other issues still need to be addressed, including any impacts of I-405 columns on the aquifer and delivery of treatment chemicals to the facility. We look forward to continuing to work with you and your staff on this important project. Sincerely, Stacy C. Trussler, P.E.

The design issues at the I-405/SR 169 interchange are examples of the complicated issues we will be solving together throughout the life of the project. The I-405/SR 169 interchange is immediately adjacent to Renton's Cedar River Park, Carco Park and the City's new Henry Moses pool. WSDOT understands the importance of these parks and facilities, and that the City of Renton takes prides in its parks and is committed to protecting and promoting their park system. At this time, it appears that any design alternative will affect the parks in some way. WSDOT is committed to minimizing any impacts as much as possible and addressing impacts through mitigation. WSDOT recognizes that mitigation solutions will be particularly important because the northbound I-405 ramp to eastbound SR 169 does affect the Cedar River Park. Issues such as visual impact, noise, and quality of park experience, among other issues, will be evaluated to identify and implement appropriate and effective mitigation. Further, WSDOT will continue to seek an appropriate and safe solution for routine operation and maintenance, including chemical delivery, for the City's water treatment facility located on the western edge of Cedar River Park. The I-405 Project Team members include not only engineers, but also professional staff with expertise in land use planning, environmental sciences, and landscape architecture. As we evaluate the park issues, we will utilize their expertise. As an example, landscape architects are an integral part of the I-405 team. The architects are helping with both the Context Sensitive Solutions work, which addresses aesthetic issues throughout the corridor, and with more specific design issues, some of which exist at the I-405/SR 169 interchange. Addressing these specific design solutions is an important part of the project, and WSDOT recognizes the role landscape architects have in developing and determining solutions to the issues surrounding Renton's parks near this interchange. COR Parks letter11 Leslie Betlach, Parks Director City of Renton Page 2 September 29, 2004 We appreciate this opportunity to clarify and confirm our commitment to addressing the many issues that are inherent in a project as large and complex as the I-405 Corridor Project.

NotesDate I-405 Corridor Overview: • S. Trussler went over tri fold handout detailing I-405 corridor project and its phases (Nickel, Implementation Plan, and Master Plan). The key point is that the Nickel is funded and is going to happen. The Implementation Plan will require extra money (some coming from RTID) and the Master Plan is the vision. None Nickel Projects: None • R. Fenton detailed the three (3) nickel projects in the South Renton area. • NB 405 auxiliary lane between SR-181 and SR-167 • SR181 on -ramp would add lane to I-405 instead of merging into freeway traffic. • Additional lane would end at SR167 off -ramp. • The whole roadway would be within existing Right -of -Way (ROW) • Retaining walls utilized to keep roadway embankment within ROW. • Drainage site would probably be within the existing ROW. • SB 167 HOV lane extension • Extend HOV lane and reconstruct on -ramp from NB I-405. • Roadway within existing ROW. • SB 405 auxiliary lane between SR-169 and SR-167 • Connect to recently constructed SB405—SB167 flyover ramp. • Replace Benson Road structure with Master Plan bridge. • Schedule would have construction start 2007 and end in 2010. • Handout (3-colorplan: green = reewa , blue = ramp, orange = Page 1 of 5 S1005%dn inVneetings\Businesses\Meeting - Hotels East Valley Office - 07-12-2004_rl.doc 1v11:1:9d1►DOkigo Notes• local roadway) Date RTID /Master Plan: • R. Fenton detailed RTID plan (similar to Implementation Plan). • Existing freeway interchange is inadequate for traffic that passes through it. I-405 team held design charette to look at interchange configuration.. Charette outcome was to separate freeway traffic from local traffic. • Current design has half -diamond interchanges at Lind and Talbot with one-way frontage roads connecting ramps. Therefore, Lind would have an on -ramp to SB405 and an off ramp from NB405, Talbot would have an on -ramp to NB405 and an off ramp from SB405, and there would be a one-way frontage road on both the north side and south side of I-405 connecting Lind and Talbot. • Access to SR-167 would essentially be the same as today (access to /from Grady Way /Rainier Ave intersection). • RTID project would add 1 mainline general purpose (GP) lane NB and SB along I-405 between I-5 and SR-167, and 2 GP lanes NB and SB between SR-167 and SR-169 with HOV and GP direct connectors between SB405 to SB167 and NB167 to NB405 • Local Roads • East Valley Roadway (EVR) is relocated to west and widened to 5-lanes. The widening of SR-167 for the new ramps and lanes is constrained by Panther Creek wetland to east and is widening from the edge of the wetland to the west. • The group noted that the relocated EVR would pass through east side of office complex and the two hotels parking lots. • M. Benoit expressed concern about parking impacts. Worried that it could make building functionally obsolete. • W. Parkinson noted that the roadway is close to the hotel buildings — especially with the replacement of the green strip. He also noted that the receiving area for the south hotel is facing EVR and is already tight for trucks. Will was also concerned about parking as the hotel was already at a minimum. B. Hanson noted that between the two hotels there is about 1 stall for every room and that the current city code is 1 stall for each room plus 2 stalls for every 3 employees. • S. Mulhall stated that the loss of parking would be mitigated. She wondered if a parking structure would be an acceptable option. • Both M. Benoit and W Parkinson said that a parking structure for there businesses would be acceptable. Page 2 of 5 S D05SadHnVneetings\BusinessesVdeeting - Hotels Fast Valley Office - 07-12-2004-r1.doc N [cam► D • B. Hanson doubted if a parking structure could be built on the hotel parcels due to space constraints with EVR and the buildings. • S. Mulhall noted that her message to the I-405 team has been that the entrances have to be similar to today (green belt). • M. Benoit wondered if it was Possible to not reconstruct EVR between SW 19'h and SW 16` , utilizing SW 19`h and Lind to reroute traffic, and signalize SW 19'h and Lind to minimize impacts to the hotels and the office building parking lots. • B. Hanson noted that EVR needs to be relocated in Master Plan to connect to rerouted Rainier Ave and that an access road would still need to be constructed from the EVR / SW 19`" intersection to keep the main entrance to the hotels. • R. Fenton thought that with this scenario we would cul-de- sac 16`" and constructs a hotel access road from the EVR / SW 19`h intersection. • M. Benoit stated that the office complex has 3 entrances and that the east building main entrance is the east driveway off of EVR. R. Fenton said that we could possibly continue the hotel access to connect to the 3rd driveway. • M. Benoit also would like the SW le cul-de-sac pushed as far east as possible and an entrance added into the office parking lot from the cul-de-sac. • Parking relocation was brought up as another possible mitigation for the impacts with the vacant parcel due west of the hotels (current plan for the parcel does not fully utilize the property). • S. Trussler stated that WSDOT cannot condemn a property for parking for another parcel. The secondary property has to be a willing participant in the sale of the property. • M. Benoit noted that relocating parking is not optimal. Having a parking lot far away from the building is not desirable for potential tenants. • W. Parkinson concurred that the hotels would not prefer parking relocation. S. Mulhall noted that she thought that hotel guests would be less willing to walk than a normal pedestrian. • R. Fenton brought up the possibility of shared parking between the hotels and the office complex. • M. Benoit thought that shared parking has possible complications incl. too many people working together between the hotels, and the future Tenants of the office Page 3 of 5 s:1005\admin�meetingslBusinesseswleeting - Hotels East valley office-07-t2-200a rl.doc r JAMUNURCUL[S Notes Actions By Date building. W. Parkinson concurred on the possible complications. • Group concurred that there could also too much overlap between when the time of hotel usage and the time of office complex usage. • W. Parkinson noted that to the public the two hotels appear under different ownership and that having parking to the north of both hotels could confuse patrons of the south hotel as to where they can park (whether or not they can park in front of the north hotel). • M. Benoit noted that of the options, the parking structure would be his preference. • R. Fenton & B. Hanson inquired into the service entrances for the office complex and the north hotel. • M. Benoit said that the office buildings service entrance is between the two buildings and the service access is the driveway off of SW 16'b. • W. Parkinson said the north hotel does not have a service entrance as the hotel as no food and beverage service. The south service entrance is at the SE corner, facing EVR. • M. Benoit wondered what the fastest timeline was for the Implementation Plan /RTID. • R. Fenton stated the earliest RTID vote is May '05. The design would be approx. 2-3 years and the construction would also be approx. 2-3 years. S. Trussler also mentioned that the schedule would also depend on the prioritization of the I-405 projects with the biennium budgets for WSDOT. This area would be priority #2 after North Renton. • 2 Handouts (3-color RTID plan: green = freeway, blue = ramp, orange = local roadway, 2 page Master Plan sheets) East Valley OOJJice Complex revisions: None • M. Benoit noted that they are in the process of doing some remodeling, reconstructing of the parking lots. • The west driveway off of Lind Ave is being moved north to line up with the west building lobby entrance. • The east driveway from EVR is to remain in the existing location but the parking lot is being reconstructed the parking lot in front of the east building lobby. • Courtyard / service entrance area being reconstructed.

The RVP properties are located north of 1-405 and south of Grady Way between Rainier Avenue and Talbot, but do not include the hotel or the three (3) Renton Place building properties. R. Fenton explained the phasing and scope of the proposed I- 405 improvements, and why a right of entry request was made for delineating existing wetlands on the RVP properties. Both C. Koeppler and M. Sandorffy expressed concern with how the drainage ditch located along the south of the RVP properties might be affected by the 1-405 project(s). They stated that they are unaware of any wetlands on their site and that the ditch is a drainage facility, which is critical to the economic viability of•their property. This ditch needs to be maintained as it collects the runoff from their site, as well as from other surrounding areas (including areas beyond Sam's Club). To address these concerns, we discussed WSDOT's obligation to maintain existing drainage facilities, as well as control water quality and quantity resulting from the proposed I- 405 improvements. C. Koeppler and M. Sandorffy will discuss the request for ROE with their civil engineers, WH Pacific.

Decision 1 i I I r J 1 I J Adak ton State luly23, 2004 Departm w//ent of Transportation Congestion Relief & Bus Rapid Transit Projects New Responsibilities for our WSDOT Management Team Beginning August 1, 2004, WSDOT's Urban Corridors Office (UCO) will be taking on responsibility for two WSDOT construction offices. UCO's Regional Administrator, Dave Dye, has assigned the Kent construction offices to Craig Stone's I-405 and SR 509 teams. Why are the two offices being transferred to the Urban Corridors Office? Recently the elected officials from the three -county region (Snohomish, King and Pierce) decided to postpone a public vote (RTID) for new revenue to construct major projects. This created an opportunity for WSDOT to look at ways to best manage projects assignments in the King County area between UCO and Northwest Region, and to balance WSDOT's available staff. UCO is charged to deliver WSDOT and Sound Transit projects in King County' s major corridors - SR 167, I-405, SR 520, the Alaska Way Viaduct, and _I--5. UCO has significant Nickel funding to construct projects on I-405 and to complete preliminary engineering in the other corridors. With our Kirkland Nickel project, UCO is transitioning from solely design/environmental teams to design and construction teams. It makes sense that UCO picks up other construction projects on their corridors. There is a logical linkage between the Kent office assignments and UCO corridors. Why the transfer to Craig Stone's management? There is a natural linkage between projects Craig has been directing and the Kent offices 'projects. Anchor projects for the Kent construction contract administration offices are the I-5 HOV Stage 4 and the SR 167 HOV Stage 3 projects. Within UCO, Craig Stone has been working on corridor projects that include our I-405 project, SR 167, and SR 509/I-5. Already, the I-405 project is being referred to as the I-405/SR 167 project, as operationally the two corridors are dependent upon one another, and function best as one corridor. Also, some of our WSDOT managers are former "South King Area" team members including Craig Stone, Kim Henry, Stacy Trussler (I-405) and Susan Everett (SR 509/I-5). Their familiarity with the South King area will help support delivery of the projects assigned to the Kent offices. How will this transfer affect the 1-405 project? Adding the two Kent offices will not affect the I-405 project. The I-405 Project Team (consultants and state members) will not change. The team has been charged to deliver the I-405 Nickel Projects and to "stand ready "for RTID-funded projects. Some of our WSDOT staff will assume larger areas of responsibility. • Craig adds I-5 and SR 167 to his management of I-405, SR 509 and SR 518. • Craig will remain the I-405 Project Director, Kim Henry will remain the I-405 Chief Engineer, and Steve Quinn will remain the I-405 GEC Project Manager.. • Stacy Trussler is responsible for everything south of Coal Creek Parkway on I-405 to the I-5 interchange (Southcenter), and down to the Pierce County line on SR 167 (includes SR 167 Stage 3 HOV, SR 167 Corridor Study and SR 167 HOT Lanes). • Denise Cieri focuses on everything north of the Coal Creek Parkway on I-405 to the I-5 interchange (Swamp Creek) - a shift in responsibilities for the Bothell/Snohomish area that used to be Stacy's. Incorporating the Kent offices into UCO strengthens the WSDOT's position to effectively deliver transportation projects within Central Puget Sound corridors. There will be improved operations as UCO will manage projects from initial planning through construction. The team leadership is very excited about the new responsibilities and the opportunities they present for project delivery. Washington State �o- Department of Transportation Congestion Relief & Bus Rapid Transit Projects KIEWU J..affett Aat Dirada ROPM..EONfire • GOP July 5, 2004 I attended a legislative briefing last week with the Washington State Department of Transportation on the I-405 Corridor Program, and I liked what I heard. The State has solid plans to deliver the Nickel transportation projects that the Legislature authorized last year. The newest construction project along I-405 is the "interim" ramp at the I-405 / SR 167 interchange that was completed last spring. I have great news! The ramp has reduced congestion measurably on I-405. In fact, the reduction has been so great that our savings in time, both commute and business, will payback the cost of the project in just months. WSDOT should be congratulated for not just aii on -time, on -budget project, but for a high value investment of our transportation taxes. I also learned that State engineers have extended the life of this ramp. Because of the great payback on the project, the state proceeded with the project even though they knew it would be replaced with the new I-405 investments. But, because of creative engineering work by the WSDOT engineers and their design -build partners, it will be used as part of the new lane being constructed as part of the Nickel projects. Further, as additional funds become available, the State is planning to incorporate this ramp when they build the larger I-405 / SR 167 interchange. So, the ramp is a good investment all the way around. The team is putting a lot of creative technical thinking into incorporating all transportation modes into the I-405 program —including HOV, transit, and bike and pedestrian trails. They will also mitigate environmental impacts early - this ensures that the environment will be restored prior to construction.

WSDOT owns and operates an extensive system oEAKra s, hi upancy vehicle lanes, park and ride lots and access ramps servingpurposetra , transit and carpools. The City of Renton is an incorporated municipalit}F h fallowing adoofed vision, mission, and business plan goals (2005-2010): Vision - Renton: A world -class city w le choose to rk, and play. Mission - The City of Renton, in partners wi b sinesses, and schools is dedicated to: • Providing ea osphere t, ive and r ise families • Encour respon le growth promoting economic vitality • Creating a J ive munity wor vironment • Meeting serve ovation and commitment to excellence Busine lan Goa Promote cit a eco development • omote nei hood vitalization • ote the Ci image in the community and region • M e servic emands that contribute to the livability of the community • Influ e ' al decisions that impact the City Final Environmenta.Impact Statement (FEIS) The complete vision for the multimodal redevelopment of I-405 was developed during a three-year EIS process that established consensus on transit, roadway, and environmental investments to be made over the next 20 years. The Final EIS describes that complete vision, or Master Plan, and it received federal approval with the Record of Decision (ROD) in October 2002. The FEIS focused on broad issues. Subsequent environmental analysis, documentation, and review will be prepared for site -specific, project -level details. June 7, 2004 Page 1 of 1 - DRAFT - As part of the FEIS process, participating agencies signed -off on three concurrence points. The CITY signed off on all three concurrence points with comments for two of the three concurrence points. Appendix A contains the concurrence points and the CITY's comments as well as CITY comments regarding scoping for the North Renton Environmental Assessment. 2. PROJECT DESCRIPTION The I-405 Corridor Program proposes to implement a multimodal system of transportation improvements to reduce traffic congestion and imp ve personal and freight mobility throughout the I-405 corridor over the next 20 ars. For the I-405 Corridor Projects, WSDOT has separated t - rridor into five ' sections. Two of the sections encompass the CITY; the to S 6 section (herein after referred to as South Renton) and the SR-169 t eek P section (herein after referred to as North Renton). s.. Master Plan The I-405 Master Plan, described in Appendix B. isear vision of multi -modal improvements to the freeway, transit, stem, and arten ong the I-405 corridor, stretching from Tukwila to Lynnwoo selected alte ' . e identified in the ROD is the basis for the I-405 Master Plan.`" Implementation Plan The I-405 Executive C endorsed a .713 Implmentation Plan on October 2, 2003. The Impleme ion P presents p 'ects that could be built over the next 10- 15 years. The ne es an ` ervices inclu • e, ithin the Implementation Plan are included in Appendix B .. Nickel P ct On A 27, 2003 the in Z Legislature approved a Nickel Funding Package whi •des $485 mi to reli . congestion at three critical I-405 traffic hotspots in Kirkland, on and Bel • e. T e funding provides for environmental, design and construction . ckel Proj. s as well as "5% Design" of the Master Plan. The new facilities and se - - s incl : ' ed within the Renton Nickel Project are included in Appendix B. y Design Refinement 4 The Implementation Plan and Master Plan phasing descriptions described above reflect what we know today based on the current conceptual -level of design and RTID funding discussions. The design will evolve as the level of design becomes more detailed, RTID funding levels are determined and design options are evaluated. The developed design is anticipated to fit within the definition of the "Selected Alternative" as documented in the October 2002 Environmental Impact Statement Federal Record of Decision. June 7, 2004 Page 2 of 2 - DRAFT - 3. PURPOSE Based on the background in the previous section, it is mutually agreed as follows. Planning, designing, constructing and operating the I-405 Corridor improvements are complex tasks, requiring maximum cooperation between CITY and WSDOT. The purpose of this Memorandum of Understanding is to establish working principles which facilitate cooperation by and between CITY and WSDOT to accomplish these tasks on those portions of the Nickel, Implementation and Master Plan that reside within the CITY. .5. 4.

The Task Force's recommendation has been reviewed by the Design Team and is being forwarded to the Administrators Executive Committee for their concurrence and action. I-405 is located between two active City parks — Cedar River Park and Liberty Park. I405 crosses over the City's sole source aquifer and the mainline alignment is located between several of the City's primary water supply wells and treatment buildings. The Wells/Parks Task Force mission is to make I-405 design recommendations that minimize impacts to the City's sole source aquifer and associated wells and the City's Parks. The Task Force's mission is challenging and complex. The attached Ramp Alignment Recommendation, which sets the conceptual footprint for I405 improvements, is a crucial first step for the Task Force. Several outstanding issues related to water treatment, operation and maintenance remain that the Task Force will continue to discuss. The outstanding issues are attached. The Task Force will submit additional recommendations to the Administrators Executive Committee as solutions are made. Thank you for this opportunity to present the Wells/Parks Task Force NB I-405 to SR 169 Ramp Alignment Recommendation. I am asking for the Administrators Executive Committee's concurrence with the Task Force's recommendation and guidance for formal adoption by the City. WSDOT and the City are committed to a continued partnership to find agreeable solutions for mutual benefit to the I405 Project, Sole Source Aquifer and City. Parks.

Although a recommended ramp alignment has been determined by the Task Force, there exist several details that require further discussion by the city. These details are: • What location and in what capacity should the corrosion control treatment building be relocated. Would a separate delivery location be feasible/acceptable for the Sodium Hydroxide and Phosphate (to be pumped to the actual treatment building or well injection points)? If pumping is allowed, how will the risk of leaks be addressed? • What access route is acceptable for the chemical delivery vehicles? Would it be prudent/acceptable to schedule off -hour (late night) deliveries? What are some operational plans that would provide the chemical deliveries in a manner that would best serve the city's interests and limit its liability? The city will discuss these issues internally and notify the Wells & Parks Task Force if further assistance is needed to facilitate a decision. Project Description (1-405/SR 169 Vicinity) Proposed improvements to the 1-405 mainline and increase of mainline footprint in the vicinity of the 1-405/SR 169 Interchange will result in the need for a new northbound 1-405 to SR 169 off -ramp. The proposed location for the ramp runs adjacent to several of the existing City of Renton primary water supply wells and treatment buildings located on the west side of the Cedar River Park. The facilities include City of Renton well #8, Well #9, a fluoridation treatment building, and a corrosion control treatment building. In order to preserve as much of the Cedar River Park resource as possible and yet minimize impact to the city's water supply infrastructure, several ramp alignment concept options have been created and analyzed. Photo 1 shows Well #8 (far left), the fluoridation treatment facility (middle), and the corrosion control treatment building (right). Photo 2 shows Well #9.

The two most realistic conceptual options for the ramp alignment were looked at in more detail per the task force recommended considerations. These options will be known as Option 1 and Option 2. Attached is an exhibit showing the alignment of the two options. Option 1 is in green and Option 2 is in orange. The Option 1 alignment design concept is the ramp alignment that exists in the current North Renton channelization plan. This option impacts both Well #9 and the corrosion control treatment building. A new well and treatment building would need to be provided along with a new access for maintenance and chemical deliveries. Option 1 avoids well #8, but it will restrict access to it. Option 2 places the new ramp alignment further east towards the park green area and closer to the community center. With the alignment located further to the East, Well #9 will not be impacted. However, the corrosion control treatment building will still be impacted by the new ramp and by a new access roadway to be installed to maintain access for maintenance and supply trucks. The corrosion control treatment facility will need to be relocated to a hew location preferably between the new ramp and the 1-405 mainline. Design Concerns and Considerations The Task Force has considered 11 areas of concern as identified by the City of Renton and 1-405 Design Team for consideration and appropriate design action as necessary. These areas of concern are as follows (also attached is a matrix of Concern and Discussion Points with additional information on each item): .1. Wells 2. Treatment Facilities 3. Utilities 4. Maintenance/Emergency Access 5. Operation During Construction 6. Cedar River Park Impacts 7. Visual Impacts 8. Heritage Tree 9. Parking J 10. Noise 11. Motorist Distraction Wells Option #1 will require relocation of Well #9. The process for locating, testing and implementing a new well is a lengthy process and the timeline could take 5-7 years or more. Furthermore, a new well may not meet production needs. It is not until after a well is drilled and tested that the actual production capacity is known. This uncertain timeline and (acceptable) production uncertainty would add much risk to project schedule with a real possibility that a new location for the well will not be feasible within the available areas. Option 2 avoids impacts to both well #8 and well #9. Therefore this option would avoid the risk of testing for and approving a new well. Treatment Facilities For both Option 1 and Option 2, the corrosion control treatment building will need to be relocated. In Option 2, there is more room between the mainline and the new ramp to locate a new facility. A conceptual design of a new AAW Washington State �r- Department of Transportation 6/14/9004 9-25 AM C�1(1/111a�imjnlm�mclll�iRRaN a1-to t log 1— Congestion Relief 6 Bus Rapid Transit Projects 600 —1081h Avenue NE, Suite 405 Bellevue, WA 98004 Main 425-456-8500 Fax 425-456-8600 corrosion control treatment building was laid out by water treatment design professionals. There are two options for location of the new facility. It appears feasible for the new building to be located either adjacent (north) to the fluoridation and existing corrosion control treatment building or just south of well #9. A plan depicting the two proposed locations along with a conceptual layout of the new building is attached. Utilities In both options, there will be relocation or modifications to the existing utilities and stormwater facilities. Maintenance/Emergency Access Maintenance access must be provided for both options. The current gated access roadway that runs around the northwest corner of the park will be cut off by both of the new ramp options. Option 1 would require new access to be provide;: to a relocated weli #9 and corrosion controi it-eatment buiiding and also maintain access to well #8 and the fluoridation building. A semi type truck must be able to maneuver and access the wells and treatment buildings. Photos 3 and 4 show the tanker truck that supplies Sodium Hydroxide (Caustic Soda Solution) to the corrosion control treatment facilities. The current delivery cycle for the tanker truck is once a month in the winter increasing to 4 times a month in the summer. It may be prudent for chemical deliveries to the treatment facilities to occur at night in order to allow truck movements through the parking areas and more importantly limit potential liability risks of the City.

Tanker truck turning around to exit park Option 2 proposes a controlled maintenance access (right in/right out) off of SR 169 between the mainline and new ramp. This access location will need-WSDOT approval as -it will -be located in a WSDOT-access controlled area. A WB-50 was modeled using Auto -Turn to verify turning movements along the access roadway. A WB-50 is a semi tractor trailer truck with a total wheel base length of 50 feet. Vertical clearances have been checked in locations where the trucks will cross under the new ramp. In both scenarios it is necessary to provide 2 access points into the park area and continued access around the community center for emergency vehicles. The two accesses should provide a 20 foot minimum roadway width for - fire access and vertical clearance for a fire truck. Operation During Construction For both options, it will be necessary for the existing treatment facilities and wells to remain in operation during construction. The new facility will be tested and approved by the city and Department of Health prior to going on-line. At the time of implementation and switch -over to a new facility, brief shut downs of the treatment facilities may be possible by coordination with the City. Strict guidelines will need to be in place to prevent contamination of the water source. These items will be included in construction scoping documents. Cedar River Park Impacts There is greater impact to the park grass area with alignment Option 2 than in Option 1. However, by not impacting the wells, the risk of locating and attaining approval for a new water source within the park property is avoided. Ramp Option 2 would be located approximately 60 feet from the community center and approximately 30 feet from the baseball diamond. Whereas Ramp Option 1 would be located approximately 80 feet from the community center and approximately 50 feet from the baseball diamond.

In both options, the heritage tree would be impacted, and therefore it would need to be removed. It should be possible to maintain the current number of parking stalls in both options. If it is necessary to impact any parking stalls, there is room to relocate the stalls. There will be increased vehicle noise in both options: Motorist Distraction For both options, when maintenance occurs on the Pumps.(every 5 years or so unless there is an emergency), the process may present a distraction to motorists. The distraction is not greater than what currently occurs during pump maintenance, but with the new ramp alignment, it will be located between the ramp and mainline. Summary The aforementioned areas of concern have been considered for the construction of both conceptual alignment Option 1 and conceptual alignment Option 2. Based on the resulting impacts and related project risk considering the committee determined areas of concern, the Task Force recommends Option 2 as the preferred alignment for the new NB 1-405 to SR 169 off -ramp. This conceptual alignment avoids impacts to both City of Renton Well #8 and Well #9 while minimizing impacts to the park green area. A key point being that by avoiding impact to City of Renton Well #9, the inherent risk associated with providing a new well source will not occur. In addition, it is feasible to relocate the corrosion control treatment building between the new ramp and mainline. This will be done while still maintaining treatment to the water supply until such a time that the new facilities are approved and ready to tie into the system. It is a requirement that emergency, maintenance and re -supply delivery access be maintained to the wells and treatment facilities. Again although the ramp alignment has been determined by. the Task Force, there remain several outstanding details for which the City desires further discussion and information to determine an appropriate direction to proceed with to complete the concept from their position. These details include: • Where and how the corrosion control treatment building would be relocated. • What access route is acceptable for the chemical delivery vehicles and are off -hour (late night) deliveries a possibility? • What are some operational plans that would provide the chemical deliveries in a manner that would best serve the city's interests and limit its liability? The city will discuss these issues internally and notify the Wells & Parks Task Force if further assistance is needed to facilitate a decision.

This Bank is potentially the win -win environmental benefit project that the I-405 Executive Committee envisioned as an early environmental investment. This letter documents our mutual commitment to continue working together towards our final partnering agreement and the Mitigation Banking Instrument (MBI). WSDOT and the City -expect the Bank -to yield -mitigation credit that -will cover-WSDOT-projects as -well as City of Renton client needs in the Service Area. The total credits that will be available will be reviewed by the Statewide Bank Oversight Committee (BOC) and controlled by the City. The details related to credit release and distribution, design, construction, operations and maintenance, and other responsibilities will be laid out in the future partnering agreement and the MBI. In general, it is expected that WSDOT will design the Bank in coordination and cooperation with the City. WSDOT will construct at least part of the Bank as well as monitor the Bank until the performance standards are met. It is also generally expected that the City will operate and maintain the site once it is constructed. The above statements do not preclude the City or WSDOT from choosing or agreeing to fund or implement any work, activities, and projects associated with the Bank. Our goal is to construct the Bank in the 2005-2007 Biennium. To this end, the I-405 Team and the City have a demanding schedule ahead of them. Key milestones are: Summer 2004 Conduct Field Studies September 2004 Bank Oversight Committee (BOC) Review Finalize Project Management Plan (PMP) Finalize Design Report Fall 2004 Finalize Partnering Agreement Prepare Permit Applications Spring 2005 Complete Site Design Finalize MBI Obtain Permits July 2005 — June 2007 Advertise, Award, and Construct Project Springbrook—LOU Gregg Zimmerman, Planning/Building/Public Works Administrator City of Renton Page 2 June 30, 2004 The Project Management Plan will include scope of work, schedule, communication plan, work sharing agreements, other draft agreements, permitting work processes, organization, schedule, and any style guidance and standards for products. Thank you for this opportunity to express I-405 Team's excitement about the Springbrook Bank. I am asking for continued partnership in development of this Bank with mutual benefit to the City. and W SDOT. Sincerely, Stacy C. Trussler, P.E.

HUD has approved the project proposal that the funds be used to develop right-of-way plans around NE 44th and along I-405. As presented to HUD, these right-of-way plans are important to redeveloping the brownfield at Port Quendall because they bring critical transportation projects closer to construction. An initial evaluation indicated that $300,000 could produce right-of-way plans for all I405 right-of-way within the City, from the northern boundary to the southern boundary with Tukwila. However, it has been suggested that the City set aside funds for its own use. Thus, if the City sets aside about 10 or 15 percent for its own use, approximately $250,000 to $270,000 is available for right-of-way plans. If this approach is approved by the Renton Executive Team, staff will direct the consultants to develop a right-of-way scope of work commensurate. with available funding. Associated with, but separate from, this right-of-way work, WSDOT has agreed to provide additional Context Sensitive Solutions (CSS) or other aesthetic improvements beyond the baseline CSS improvements identified through the CSS committee process. The following describes options and issues for establishing agreements and determining the appropriate aesthetic improvement. AGREEMENTS For simpler HUD tracking and potential auditing, staff suggests that the agreement for the right-of-way work to be performed by WSDOT only address HUD monies, and not address Context Sensitive Solutions. The Context Sensitive Solutions agreement would be on separate, but parallel and concurrent process. - Staff suggests standard WSDOT agreement for right-of-way plans. (It's just simpler; a non- standard agreement is fine, it just requires more review and negotiation.) - Staff suggests a Memorandum of Agreement for CSS work, though an Memorandum of Understanding could also be a possibility. The memorandum should clarify at least the following issues: How to assure CSS above established baseline in agreement as that baseline is not yet established. How to assure follow-through given the potential long time between MOA/MOU and implementation. How to assure follow-through given funding uncertainties. • Move right-of-way plans and CSS agreements together simultaneously and have signed at the same time. (See attached Table 1, Simultaneous Agreement Process) PROJECTS ROW-CSS Process-Sched for City Exec 7-23-04-Final1 7/16/20043:05 PM • Project ideas vary and cover a wider range of possibilities. These are presented in Table 2, Context Sensitive Solution Possibilities and Related Ideas. The three main categories of ideas are summarized below. - Projects could potentially be associated with the I-4O5 Nickel project work and therefore be implemented sooner, while projects associated with the Implementation Plan would be implemented further in the future. - Projects could be "removable and re -installable" projects, such as lights, that could be installed in the near -term and then re -used with the I-4O5 Implementation phase. - Possibly acceptable projects may not be strict CSS improvements, but could be related to the I- 405 Early Environmental Implementation process. • The Renton Executive Team may identify additional project ideas as they discuss the categories and potential projects described in Table 2.

The traffic analysis for the Talbot interchange showed that the local network for all the considered options operated at an acceptable level of service for 2030 implementation plan traffic, with no substantial differences between configurations. Likewise, there was no discernable difference in the mainline operations between options. All configurations have impacts on nearby properties. They vary on which properties are impacted, but as a whole there is little difference between configurations. To evaluate the interchange options, the configurations were separated for northbound and southbound to identify the best possible solution for each side of interchange. The options were separated into different groups for both northbound and southbound based on each interchange configuration. Southbound Southbound options were grouped with other configurations with the same features. A major feature used to evaluate the southbound options was whether or not a bypass was provided for Lind Ave traffic. Both subsets were then divided on if the configuration cul- de-saced South Renton Village Place (SRVP). The No Bypass / No Cul-De-Sac group was then further split into whether the connection was a one-way or two-way connection to/ from Talbot. See Table 1 for the southbound configuration groupings. Table 1 Southbound No Bypass B ass Cul-De-Sac SRVP No Cul-De-Sac Cul-De-Sac SRVP No Cul-De-Sac One-way Two -Way A-1 D-1 K-1 A-2 D-2 K-2 D H K B-1 B-2 We first compared southbound configurations with and without the bypass. The two --options with -the -bypass; B-1 &-B-2; were -found less -desirable: Although -these options had a shorter travel time for Lind Ave traffic, the additional overhang over Main St. in front of Filename: S:\005\roadway\concepts\Talbot Options\Talbot Summary.doc Printed 7/16/04 Talbot Interchange Screening DRAFT - July 16, 2004 Page 2 of 3 Renton City Hall needed for the bypass would force the structure to have outriggers (straddle bents) instead of being a cantilever, and otherwise complicate the reconstruction of I-405 in the vicinity of Renton City Hall. The next comparison was between configurations with and without connection to SRVP. The options without this connection, A-1, D-1, and K-1, were found less desirable. Eliminating the connection to Talbot combined with closing of the southern most driveway along Talbot for Two Renton Place would severely inhibit ingress and egress to both One and Two Renton Place buildings. At this time both the one-way and two-way connections appear to be the desirable options. Assuming the two-way connection could have driveways, it would allow for greater access to/ from the commercial businesses and would have the have greatest possibility of reusing the existing braided flyover ramp structure. The advantages of the one-way connection would be that Lind Ave traffic would pass though one less signal and that it would be slightly more intuitive for drivers heading to Lind Ave as well as Talbot traffic trying to get on southbound 405. The southbound configurations carried forward are A-2, D-2, K-2 group and the D, H, and K group. (Update: After discussions with John Milton, the configuration group with D, H, and K would not have access from the frontage road into the One Renton Place and Two Renton Place parking lots. Therefore, this group is changed -from -desirable, -to undesirable.) Northbound The northbound configurations were also grouped together with other configurations with the same features. As with the southbound groupings, the main feature identified was the bypass for Lind Ave traffic. The configurations with the bypass were then divided into the type of interchange, whether it is a diamond on -connection or a loop on -connection. The Bypass / Loop Ramp group was then further split into whether the Talbot Hill access was relocated or remained in the existing location. See Table 2 for the northbound configuration groupings. Table 2 Northbound Bypass No Bypass Diamond Ramp Loop Ramp Relocated Access No Access Change. A-1 B-1 D K A-2 B-2 D-1 K-1 H D-2 K-2 We first compared northbound configurations with and without the bypass. The three options without the bypass, A-1, A-2 and H were found less desirable. Providing the bypasses reduced the travel time for NB405 traffic by roughly 50 seconds, but at a higher cost for constructing an additional bridge over Talbot Road and increased pavement and -earthwork-for-the off4amp to Talbot - Also,- the'NB on=ramp from Talbot road -with the Filename: S:\005\roadway\concepts\Ta1bot Options\Talbot Summary.doc Printed 7/16/04 Talbot Interchange Screening DRAFT - July 16, 2004 Page 3 of 3 bypass has less storage because of the need to merge with the collector -distributor roadway prior to entering the freeway. The next comparison was between the loop ramp configurations with and without the Talbot Hill/ South 151h intersection access relocated. The configurations with the Talbot Hill access remaining at South 15th St options, K, K-1, and K-2, were found less desirable. These options were deemed less desirable because of the complexity of the South 15th, Talbot Road, Puget Drive South, and NB405 on -ramp intersection as well as the separation between the NB405 on- and off -ramps. At this time both the diamond on -connection with bypass option and the loop on - connections with the bypass and relocated access option appear more desirable. The benefits of the loop connection include shorter and fewer retaining walls and less impacts to Berkshire Apartments. The loop ramp also avoids the canyon effect the diamond ramp would have between Talbot Hill and the NB405 C-D. The advantages of the diamond ramp include less impacts to the Renton Plaza office complex (only 1 driveway within limited access lines, not both), and less impacts to the Talbot Hill neighborhood. The northbound configurations carried forward are the B-1 and B-2 group and the D, D-1, and D-2 group.

Ron and I have been information gathering to see how favorable things look for the Springbrook site. Our new senior fish biologist, Paul LaRiviere worked with Witter and came up with some new ideas that could make it even more favorable. Ron's recent information gathering has made the site(s) look more favorable as well. In addition, Barb Aberle has some ideas on the banking side as well as about the site. I see the next step as our team, Ron's team, Barb, Levy district (Larry Capellaro.), and Gail Terzi (corps) getting together in the field to see if the ideas from the parties are agreeable enough to continue pursuing. In my mind, an agreeable outlook would mean a preparation meeting for environmental and design concepts and then a presentation to 405 decision makers about those concepts and potential deal structures. If I am unable to contact Ron before this Friday, I am asking Witter to follow up in my absence next week. Thank you. Sharon Sharon L.

We received comments and/or project ideas from Renton, Kirkland, Bellevue, Issaquah, Bothell, as well as WSDOT's preliminary watershed characterization data for Renton. If I have left anyone out that sent something in, please let me know because I do not show it in our current information. Thank you to everyone for all of the hard work and effort on those submittals. We are currently compiling the updates and you should expect to hear from an EEI team member for follow up information and site visit coordination. After we gather as much information as possible in the time we have (until about the end of February), we will evaluate and score the projects based on what we've learned. According to our schedule, we will send the results and recommendations to you mid -March. We plan to follow up with another EEI Task Force meeting the last week of March to present those results. While this is an aggressive schedule, we plan to stick to it so that our design work may include some Spring monitoring and research. Your involvement and availability for field visits, meetings, and/or telephone calls is an important part the successful outcome of our EEI program. Thank you.

BACKGROUND WSDOT is a department of state government with all powers, duties, and functions to coordinate transportation modes and to develop and maintain a statewide transportation system meeting the needs of the State of Washington as provided in RCW chs. 47.01. WSDOT owns and operates an extensive system of high occupancy vehicle lanes, and access ramps serving transit and carpools. On , 2003 the Washington State Legislature approved gas tax funding of $485 Million Dollars, for projects within the I405 portion of "Nickel Projects". The funding provides for funding of environmental, design and construction of Nickel Projects as well as "5% Design" of the Master Plan. The new facilities and services included within the Renton Nickel Project include: • One additional I-405 northbound auxiliary lane between the SR 181 on - connection and the SR 167 off -connection. • One additional I-405 southbound auxiliary lane between the SR 169 on - connection and the SR 167 off -connection. • Extension of the SR 167 southbound HOV lane north to I-405. Planning, designing, constructing and operating these improvements are a complex task, requiring maximum cooperation between COR and WSDOT. The I-405 Executive Committee endorsed an Implementation Plan on October 2, 2003. The Implementation identifies the South Renton Project as I-405 south of the Cedar River to 1-5 and the North Renton Project as 1-405 from the Cedar River to I-90. The Implementation Plan includes the following elements within the South Renton Project: • One additional eastbound general-purpose lane under I-5, connecting SR-518 to I- 405 with a two-lane section. • One additional lane in each direction of I-405 from the I-405/I-5 (Tukwila) interchange to the I-405/SR-167 interchange. • Two additional I-405 lanes both northbound and southbound from the SR-167 interchange to SR 169. • One additional auxiliary lane in each direction of SR-167, southbound from I-405 to the SW 41" off -connection, and northbound from the S. 180`h on -connection to I-405. • Replacement of the 61 Sc Avenue South, 66`h Avenue South, Lind Avenue Southwest, and Benson Road South structures over I-405 to accommodate the widened I-405. • Removal of the Tukwila Parkway to northbound I-405 "slip" ramp and extension of the Tukwila Parkway east over the Green River to a new intersection with SR- 181. This improvement will provide traffic on Tukwila Parkway access to northbound I-405 through the reconstructed south half of the I-405/SR-181 interchange. • Reconstruction of the south half of the I-405 SR-181 (northbound only) interchange to connect the I-405 northbound off -ramp to the proposed Tukwila Parkway extension. • Reconstruct the SR 167 interchange as two independent interchanges at a shared location: o One interchange to handle the I-405 to SR-167 system -to -system traffic by constructing a freeway -to -freeway direct connector for southbound I-405 to southbound SR-167 general-purpose traffic, constructing freeway -to - freeway direct connectors between SR-167 and north I-405 for HOV traffic, and improving the northbound SR 167 to northbound I-405 ramp. o A second interchange to handle I-405 to local (Renton) streets traffic by constructing a one-way frontage road couplet system with proposed I-405 connections to Talbot and Lind, and no connections to SR-167. o Three of the four existing I-405/SR-167 interchange "loop" ramps will be removed and replaced with the interchange improvements noted above, with only the northbound SR-167 to southbound I-405 ramp remaining in operation. • Expanding Park & Ride facilities (location undetermined). • Construct an I405 facility that accommodates the "Master Plan".

PURPOSE The purpose of this Memorandum of Understanding is to establish working principles by and between COR and WSDOT to facilitate the design, construction, and operation of capital projects of those portions of the Nickel and Implementation Plan that reside within the COR. 3. GOALS The goal of the principles is as follows: • Describe the general relationship between WSDOT and COR that will facilitate delivery of the Nickel Projects and the 5% Design beginning from the early stages of planning [such as NEPA Environmental Assessment document(s)] throughout the final stages of construction. • Commit to expedited processes for planning, designing and constructing projects and integrating programs. • Provide attachments pertaining to the relationship between WSDOT and COR as well as the overall I-405 Project's organizational structure. • Declare intent to execute future Memorandums of Agreement to implement the Nickel Project, and as funding becomes available, the projects within the Implementation Plan. 4. PRINCIPLES A. Nickel and Implementation investments are first and foremost to improve access, speed, and reliability of the I-405 corridor for the traveling public and public transit. B. The projects and services implemented for I-405 will be of high quality, consistent with approved financial plans, and open for service on schedule. C. It is acknowledged that both the COR and WSDOT are committed to high -quality transportation services and the long-term interests of the citizens of the I-405 Corridor. D. WSDOT and COR will coordinate respective capital programs to take advantage of opportunities to reduce cost and increase benefit. Allocation arrangements will be negotiated within individual agreements between relevant entities to ensure that the cost of joint projects is assigned on a proportional basis. E. WSDOT and COR will work together to pursue additional grants or other funds where value can be added to specific capital projects or where added projects can add significant benefits to I-405 mobility. F. Construction schedules will be coordinated and managed such that disruption to the public and construction contracting community is kept at acceptable levels. G. Recognizing the above principles and the complexities of the tasks involved in them, COR and WSDOT will expedite processes, including but not necessarily limited to: • Identify qualified representatives to ensure timeliness and effectiveness of discussions and decisions. • Organize functions to ensure good communication between team representatives and between teams and the respective organizations. • Assure the respective organizations will expedite the reviews and approvals related to this Memorandum of Understanding within the agreed upon schedules. • Processes will be evaluated on an on -going basis to minimize time required to design and construct projects, and when possible, run processes in parallel instead of sequentially. H. WSDOT will perform the lead role on I-405 Corridor community involvement and provide public information and involvement roles for COR when appropriate. I. It is pledged that issues of conflict will be referred to the appropriate resolution process to reach agreement expeditiously and at the lowest level of hierarchy. The spirit of these discussions will ensure rapid resolution, maximum cooperation, respect for financial responsibilities, and high integrity of individuals and organizational missions. 5. STRUCTURE COR will, in coordination with WSDOT, provide a recommended list of Renton City staff to comprise the I-405 "City Design Team". This committee will be referred to as, the CDT. In coordination with WSDOT, the CDT will assess design impacts to the City and develop design recommendations/solutions. The CDT will provide a central COR forum by which WSDOT can bring preliminary design sketches and information to gain COR feedback. The WSDOT will provide the South Renton and North Renton Contract Managers, the S. Renton/N. Renton/Bothell Segment Manager, and as appropriate other WSDOT staff or consultants to support the CDT. As appropriate, the CDT will form Task Forces to coordinate on specific issues. The Task Force will appoint a chair to report back to the CDT. The Task Forces will cease when the reason for forming has been resolved. As the project progresses, the CDT will also continue to provide feedback to WSDOT as the Design Builder selected to build the Renton section of I-405 projects brings refined designs to WSDOT for approval. The COR will form an Administrators Executive Committee for the CDT to provide updates to, make recommendations to, and to receive policy direction from. This committee will represent the COR for final issue resolution. This committee will also provide recommendations to the mayor and city council. See Exhibit _I_ for the organizational structure of COR/WSDOT coordination. 6.

For Washington State Department of For City of Renton Transportation Name Name Title Title Keith Woolley - Asundry405 stuff Page 1 From: Shawna Mulhall To: Afzali, Nick; Meyer, Sandra Date: 1 /21 /04 10:58AM Subject: Asundry 405 stuff The MOU, on page 3, states that 44th is being reconstructed to accomodate mainline widening and future area improvements. I think we might want some caveat language in here as I think some additional improvements to 44th would be required if Port Quendall were built. It is my understanding that the 44th design could be modified to accomodate that level of growth, but it is not being built for that level of growth. Consequently, I am not sure the language in the MOU is quite right. Also, I have a slew of questions about the Talbot options. I've colored all my options in bright, green, yellow and pink, for local access, mainline and HOV lanes. It's a befuddling array of options. Do I recall correctly that we would meet on this, or should I try and put all of my befuddlement into an email?

I will develop the language to be incorporated into the MOU. I will forward the draft language to you for your review as well. Please let me know if you have any questions. >>> Lys Hornsby 01/14/04 08:49AM >>> Also, Nick: Since Renton's aquifer is a sole source aquifer, there are certain protections that we have if federal funding is used on a project. The USEPA (and Renton) must approve an environmental protection plan to protect the aquifer. We want to make a very strong statement with this tool! The fact that we are working in a sole source aquifer should be emphasized in the MOU and the requirement for an independent environmental coordinator and plan should be listed as a minimum requirement. We did a very similar thing when the s-curves were taken out.

BACKGROUND WSDOT is a department of state government with all powers, duties, and functions to coordinate transportation modes and to develop and maintain a statewide transportation system meeting the needs of the State of Washington as provided in RCW chs. 47.01. WSDOT owns and operates an extensive system of high occupancy vehicle lanes, and access ramps serving transit and carpools. On , 2003 the Washington State Legislature approved gas tax funding of $485 Million Dollars, for projects within the I-405 portion of "Nickel Projects". The funding provides for funding of environmental, design and construction of Nickel Projects as well as "5% Design" of the Master Plan. The new facilities and services included within the Renton Nickel Project include: • One additional I-405 northbound auxiliary lane between the SR 181 on - connection and the SR 167 off -connection. • One additional I-405 southbound auxiliary lane between the SR 169 on - connection and the SR 167 off -connection. • Extension of the SR 167 southbound HOV lane north to I-405. Planning, designing, constructing and operating these improvements are a complex task, requiring maximum cooperation between COR and WSDOT. The I-405 Executive Committee endorsed an Implementation Plan on October 2, 2003. The Implementation identifies the South Renton Project as I-405 south of the Cedar River to I-5 and the North Renton Project as 1-405 from the Cedar River to I-90. The Implementation Plan includes the following elements within the South Renton Project: • One additional eastbound general-purpose lane under I-5, connecting SR-518 to I- 405 with a two-lane section. • One additional lane in each direction of I-405 from the I-405/I-5 (Tukwila) interchange to the I-405/SR-167 interchange. • Two additional I-405 lanes both northbound and southbound from the SR-167 interchange to SR 169. • One additional auxiliary lane in each direction of SR-167, southbound from I-405 to the SW 4 1 " off -connection, and northbound from the S. 180`h on -connection to 1-405. • Replacement of the 61 S` Avenue South, 66`h Avenue South, Lind Avenue Southwest, and Benson Road South structures over I-405 to accommodate the widened I-405. • Removal of the Tukwila Parkway to northbound I-405 "slip" ramp and extension of the Tukwila Parkway east over the Green River to a new intersection with SR- 181. This improvement will provide traffic on Tukwila Parkway access to northbound I-405 through the reconstructed south half of the 1-405/SR-181 interchange. • Reconstruction of the south half of the I-405 SR-181 (northbound only) interchange to connect the I-405 northbound off -ramp to the proposed Tukwila Parkway extension. • Reconstruct the SR 167 interchange as two independent interchanges at a shared location: o One interchange to handle the I-405 to SR-167 system -to -system traffic by constructing a freeway -to -freeway direct connector for southbound I-405 to southbound SR-167 general-purpose traffic, constructing freeway -to - freeway direct connectors between SR-167 and north I-405 for HOV traffic, and improving the northbound SR 167 to northbound I-405 ramp. o A second interchange to handle 1-405 to local (Renton) streets traffic by constructing a one-way frontage road couplet system with proposed I-405 connections to Talbot and Lind, and no connections to SR-167. o Three of the four existing I-405/SR-167 interchange "loop" ramps will be removed and replaced with the interchange improvements noted above, with only the northbound SR-167 to southbound I-405 ramp remaining in operation. • Expanding Park & Ride facilities (location undetermined). • Construct an 1-405 facility that accommodates the "Master Plan". The Implementation Plan includes the following elements within the North Renton Project: • Construct 2 additional lanes in each direction of I-405. • Reconstruct SR-169 Interchange - replace with a SR- 169/N 3`d Street split diamond interchange. • Accommodates future NB & SB Direct Connector ramps between 1-405 and SR- 169. • Accommodates proposed Sound Transit HOV-DA facility at N 81h. • Reconstruct I-405/Park Interchange to accommodate mainline widening. • Accommodate future truck climbing/auxiliary lanes. • Reconstruct NE 301h Interchange to accommodate mainline widening. • Reconstruct May Creek bridge. • Reconstruct NE 441h Interchange to accommodate mainline widening and future area improvements. • Construct a HOV-DA facility at 76`h Street (vicinity of NE 441h Interchange). • Accommodate future truck climbing/auxiliary lanes. • Reconstruct/Relocate NE I I2`h to accommodate mainline widening and proposed transit improvements. • Construct an In -Line transit station west of the NE 1121h Park & Ride • Add capacity to the NE 112`h Park & Ride • Reconstruct Coal Creek Interchange to accommodate mainline widening.

Develop a shared understanding of what Design -Build is and how it works. - 2. Gather information, concerns and questions related to design -build. 3. Outline next steps for learning about how Design -Build will be used on I- 405_ and how it may affect the environmental approach. This is the first of two proposed Design -Build workshops between the WSDOT and Environmental agencies. This workshop is to introduce the attendees to a way of highway construction that is fairly new to Washington State At the next workshop, the attendees will come back together to work on developing new and better ways that we can do business together utilizing Design -Build.

It is our understanding that the 1-405 Team has carefully consideredthe two City -owned bank sites and the Lower Springbrook project, but is now investigating other short-listed sites outside of the City of Renton. October 2&Letter Summary As summarized in your October 281h letter, the challenges faced_by the sites are: Site 1 (west side of Oakesdale Avenue SW. between SW .27`h and SW 34`h Streets) ■ Site 1 has limited natural wetland potential due to its inability to. support groundwater -fed wetlands. ' Site 2 (triangular parcel along Springbrook Creek on east side of Oakesdale Avenue SW) .■ WSDOT's understanding is that the City of Renton has reserved much of Site 2 to. compensate for previous wetland fill that occurred in other parts of the City. Lower Sprin bg rook . There is an engineered_ flow control structure between Lower Springbrook Creek, and the Green River, and Lower Springbrook Creek is a highly regulated channel. November. 24 Meeting Summary Further explanation regarding the challenges faced by these sites were discussed in our November 24"' meeting: ■ The three Renton sites provide minimal benefit to endangered species, such as fish. Large-scale upland habitat benefits is one of the identified goals of the EEI Program. • The limited amount of non -wetland acreage available after City commitments and WSDOT needs would not justify a banking agreement. There are roughly 19 non -wetland acres available on the two sites. WSDOT's understanding was that Site 2, which holds more promise for a successful wetland, is currently all spoken for under the City/Glacier Park Agreement. ■ ..For wetlands to be rated Class A, they need some type of buffer, which would be. difficult to accomplish with our two bank sites. 1055 South Grady Way - Renton, Washington 98055 ® This paper contains 50 % recycled material, 30 % post consumer RENTON AHEAD OF THE CURVE January 7, 2004 Page 2 The timeframe for the EEI Program is for final design plans to be complete in July 2005, which would be a challenge if a banking agreement were pursued. WSDOT's EEI Program is striving for a single larger project rather than many smaller sites. Continuation of City / WSDOT Coordination • Through your October 28 letter and the November 24 meeting, we better understand WSDOT's findings regarding the limitations of our three sites with respect to an Early Environmental Investment project. We understand that WSDOT is interested in implementing an *EEI project that will provide the most environmental benefit as possible to regionally important natural resources including listed species. Since Springbrook Creek in Renton has relatively limited use by Chinook salmon compared to the main stem Green River, the Renton site may not be the best available location for the EEI Program project. • Regarding some of the limitations with regards to our two wetland bank sites, we have some flexibility with regards to previous commitments. We are obligated to provide a total of 5.33 acres of wetland mitigation within the wetland bank per the City/Glacier Park Agreement. WSDOT's assumption that the full 5.33 acres of mitigation had to occur on Site 2 (south site) is not correct. We are willing to work= with` WSDOT. on developing the Site 2 only - if that site would achieve WSDOT's environmentat,,.goals. In addition, the need for the 5.33 acres of mitigation was per our original Wetland:ordinance, which,, may not have been required if the City/Glacier Park Wetland Bank `Agree dhV-was established under current City wetland requirements. We will clarify these commitments and relay. thisinformation to WSDOT. • We still extend the offer to otentiall r- p y partner. with WSDOT regarding development of the two wetland bank sites :The poteritiahexiststhat these sites may be used as mitigation sites during the I-405 project, rather than use as.: ant,EEI PK.ogram=:project. j:The ;development of the Wetland Mitigation Bank sites could be used forother environmental impacts such as flood control. • We are still concerried about impacts thin tiOVity of Renton being mitigated far outside our city limits. Most of.the I-405 project impacts within the City;=ofRenton are along SR 167. The loss of large areas of wetlandssin our City has consequences thaf'will need to be reviewed from a City regulatory perspective and as, a ~-general. public policy, - by our City Administration, the Council, and the public. These we,tlandsprovideyimportant:functions such as flood storage, water quality treatment, groundwater recharge' .'that provides base flows to streams and support fish, along with fish and wildlife habitat'within.our;,City. We understand that WSDOT may mitigate for these impacts at another location - not within Renton. We are concerned that this action would significantly degrade the water resources within our jurisdiction. Thank you for this opportunity to clarify our understanding with regards to the status of the I-405 Early Environmental Investment Program within the City of Renton. We look forward to continued coordination with the I-405 EEI Program.

Redevelopment Planning: The Plant is divided into three planning areas. At the time at which property is made surplus, a conceptual plan must be completed for the entirety of the corresponding area. The Plan must be adopted by the City Council and will serve as the basis for all future permits applications. Adoption of this Agreement grants approval for the Conceptual Plan for Subdistrict 1A (Lot 3 and 10-50), showing an integrated retail development made up of large and medium -format retail stores, as well as small shops oriented along Park Avenue, totaling 550,000 sf. Structured parking and/or upper -story residential or office development could occur in initial or subsequent phases. It is assumed that this development will generate $1.2 million a year in one-time revenues to the City and recurring revenues escalating to $1.5 million a year by 2009. Infrastructure Funding: Renton agrees to pay for the required arterial roads and trunk line utilities (water, stormwater and sewer). $1.5 million in 2003 year-end fund balance will be earmarked for roadway design and work will begin immediately. The road and utility network has been segmented to allow for phased construction that corresponds with actual redevelopment. For example, if initial redevelopment only occurs in a discreet area, only the infrastructure required to serve that development would be constructed. City staff has calculated preliminary cost estimates for the required Infrastructure: Subdistrict 1A (full buildout) $12.1 million Subdistrict 1 B (full buildout) 2.1 million District 2 (full buildout) 19.2 million TOTAL $33.5 million The City will issue bonds to fund infrastructure costs. Therefore, the City only agrees to construct infrastructure if redevelopment is anticipated to generate enough tax revenue to pay the obligated debt service. The City will set aside two-thirds of all revenue generated by redevelopment to pay debt service. The remaining one-third will be used to fund general governmental services. Boeing will dedicate to the City all required right of way at no cost. Boeing will pay a share of the cost of the intersection improvements providing access to its property (left -turn lanes, signals, etc). Boeing or future property owners will build all additional infrastructure (local roads, utility systems, etc.). Vesting: Boeing is vested to the Comprehensive Plan Vision and Policies and the zoning use table for the term of the agreement. The Conceptual Retail Plan for Subdistrict 1A is vested to development regulations (including design guidelines) for three years. Future Conceptual Plans are vested to development regulations in place at the time of approval for three years, with the exception of a District 2 Conceptual Plan, which would vest for five years. Additional vesting periods will be granted with subsequent land use (master plan or site plan) approval. At any time, Boeing may elect to adopt future changes to the City's Land Use Policies and regulations. Further, the City reserves the authority to impose new public health and safety regulations, such as the upcoming adoption of the International Building Codes. Renegotiation: If these assumptions or strategies change significantly, the parties may jointly elect to renegotiate the Agreement.

Secondarily, it articulates the pri- mary technical limitations of these findings. Appendices with tables and maps support the narrative. A detailed report with all supporting documentation will be available after January 1, 2003. Report Contents This report includes the following: • A narrative description of watershed characterization findings of potential off -site mitigation options and limitations of those findings • A spreadsheet of potential mitigation options with accompanying resource data • Large -format maps that identify the location and extent of potential mitigation sites by mitigation area Introduction Watershed characterization is an emerging planning and technical tool. It identifies alterna- tive mitigation opportunities to conventional stormwater Best Management Practices (BMPs) and on -site wetland and habitat mitigation options. The goal of watershed characterization is to provide the project management team with viable mitigation options that have potential to increase environmental benefits and reduce project cost. Watershed characterization assesses condition of surrounding natural resources and seeks a more complete understanding of pro- ject effects. It also identifies potential mitigation options that have the greatest opportunity for maximizing environmental benefit, while reducing cost. Through this approach, we iden- tify all viable alternative mitigation options and then systematically assess restoration poten- tial, environmental benefits, and cost for each potential mitigation site. For example, a con- ventional stormwater design calls for engineered detention ponds or vaults to manage runoff from new impervious areas. However, when high groundwater, high land values, or other site limitations preclude conventional designs, project cost can skyrocket. Watershed characteri- zation seeks to identify other sites that, when restored, provide the required stormwater as well as numerous other environmental benefits. These other sites might be degraded wetland, riparian, and floodplain areas or might be older developments with untreated runoff. There are many factors that influence the mitigation opportunities that exist in a particular watershed. Geology, topography, precipitation, and human land use are key factors that dic- tate the number, location, and extent of alternative mitigation options available. Some water- sheds have many wetland systems that buffer streams from sediment, pollutants, and peak flows, while others have very few. Within our study area, Coal and May Creeks are adjacent watersheds flowing into Lake Washington. Because of the geology and topography of the Coal Creek watershed, very few wetlands occur here, even under pre -European settlement conditions. Conversely, May Creek watershed has large wetland complexes associated with old glacial outwash channels and scars. Human land use also plays a major role in the oppor- tunities available for alternative mitigation. The North Renton/John's Creek watershed up- 12/1/03 Preliminary Findings: Watershed Characterization I-405 North Renton slope of the project area consists of three large residential developments. Any wetlands that once existed have been filled and developed and homes encroach on the little remaining ri- parian area, resulting in no wetland or riparian restoration opportunities. In other situations, large wetlands have been drained and the parts of the site developed for residential or com- mercial uses, precluding any opportunity to restore natural hydrology to the wetland system. Methods Watershed characterization consists of three key analysis steps. • Step one seeks to understand how water, sediment, pollutants, large wood, and heat are delivered to and routed through stream systems within the study area and how human land use has altered these key ecological processes • Step two assesses the potential direct project impacts to natural resources • Step three identifies, assesses, and ranks potential mitigation sites We estimated project impacts using natural resource databases and preliminary project plans. WSDOT's MGS flood model was used to estimate flow impacts and storage needs from ret- rofitted and new impervious areas. We overlaid the estimated project footprint on riparian and wetland maps to identify impact areas for these resources. We used fish habitat surveys and wildlife inventories to identify impacts to fish and wildlife habitat. We identified potential mitigation sites by creating a restoration site data set for wetlands, riparian areas, and floodplains. We also identified urban areas where stormwater retrofit pro- jects could address existing stormwater runoff problems. Wetland, riparian, and floodplain data sets were developed using available data and extensive photo interpretation. These data sets differ from existing data in that we sought to identify potential restoration sites (de- graded or destroyed sites that have potential, if restored, to meet mitigation needs), rather than inventorying existing wetlands, riparian areas, and floodplains. Four data sets served as the pool of available off -site potential restoration sites. The data sets are: • Wetland • Riparian • Floodplain • Stormwater retrofit Sites within each of the four data sets were evaluated and ranked for stormwater mitigation potential and natural resource mitigation potential by the technical team using a series of rules that integrate both site characteristics and landscape conditions. Key factors used to rank potential stormwater mitigation sites include: • Environmental benefit • Proximity of the site to the I-405 project area • Condition of target ecological processes 12/1/03 -- Page 2 Preliminary Findings: Watershed Characterization I-405 North Renton • Local recovery priorities • Adjacency to public lands • Natural resource type • Site size Factors used to rank potential wetland and habitat mitigation sites include all those used for ranking stormwater sites with the exception of the proximity criteria. Staff discipline experts conducted initial field visits on most of the ranked potential stormwater mitigation sites as a final quality control step, and deleted sites which they determined to have minimal restora- tion potential. We did not make field visits to wetland and habitat mitigation sites unless these sites are on the stormwater mitigation site list. During field visits, biologists did a pre- liminary assessment of wetland, riparian, and floodplain functions each site would provide if restored. This information is being used to compare the environmental benefits of off -site mitigation options to more conventional on -site options. Preliminary cost estimates are being developed for a similar comparison of off -site versus on -site mitigation costs. We then organized the highest ranking candidate stormwater flow control mitigation sites within each data set into one of six stream catchments that lie upslope of the project, called stormwater mitigation areas. Boundaries coincide with criteria supported by Department of Ecology staff for off -site mitigation of stormwater flow control. This organization led to the development of a priority list of potential stormwater mitigation options for each mitigation area. It is important to note that we focused on flow control mitigation, and did not attempt to ad- dress mitigation of water quality impacts. In most cases, stormwater quality impacts can be mitigated through conventional on -site best management practices, and there is still consider- able uncertainty about how to demonstrate that off -site mitigation can meet regulatory re- . quirements for water quality. Using a similar process, we organized the highest ranking candidate sites for mitigating wet- land and habitat impacts into one of six stream catchments. We call these conservative natu- ral resource mitigation areas. These areas coincide with local jurisdiction preferences to miti- gate wetland and habitat impacts in the same stream catchment in which they occur. These areas are similar to the stormwater mitigation areas, but include additional land downslope of the project. This organization led to the development of a priority list of potential wetland and habitat mitigation options for each mitigation area. For the final ranking step, we organized the highest ranking candidate sites for mitigating natural resource impacts for the entire study area. This led us to an overall priority list of po- tential wetland and habitat mitigation options for the entire study area. Throughout this watershed characterization process, we pursued a close relationship with a variety of local and regional entities. Early in the process, we met with the Muckleshoot Tribe, King County Water Resource Inventory Area (WRIA) 8 staff, and staff of cities in the project area. Data coordination, identification of mitigation sideboards, and establishing an ongoing channel of communication with these groups were some of the most important sub- jects of these meetings. We made a determined effort to use data standards which were com- 12/1/03 -- Page 3 Preliminary Findings: Watershed Characterization I-405 North Renton patible with those used in WRIA 8 by local watershed efforts. Where their data analysis wasn't complete, we used compatible methods in our own data development so that our analysis would be available for their use. In order to keep the lines of communication open with this diverse and large group of stakeholders, weekly status reports were sent out by the project team, detailing progress. Late in the process, we held a "debriefing" meeting with lo- cal staff to communicate our preliminary results. We also stayed in close communication with the WSDOT Urban Corridors staff and contrac- tors who were most involved in the environmental aspects of the I-405 North Renton project. With these staff, we presented information about our watershed characterization process with various stakeholder groups including the I-405 Technical Committee and the I-405 Steering Committee. Findings General Findings It is important to state up -front that watershed characterization is not the "silver bullet." Wa- tershed characterization should not and will not replace on -site mitigation of transportation impacts. However, in the past, on -site mitigation was often the only mitigation option, and when site attributes limited potential to apply standard BMPs, mitigation cost skyrocketed and environmental benefits were marginal, but considered the best under the circumstances. Preliminary findings indicate that it is possible, even likely, that watershed characterization can identify potential off -site mitigation options that are capable of meeting mitigation needs, while increasing environmental benefits and reducing mitigation cost. The proposed I-405 North Renton project could have stormwater, wetland, riparian, and habitat impacts. Stormwater impacts, however, are likely to dominate mitigation needs. Although we identify flow control storage volumes and mitigation for all of the project drain- ages, several of these areas may not need stormwater mitigation for flow control. The Lakehurst, Kennydale, and North Renton/Johns Creek areas drain primarily through urban storm drain systems to Lake Washington, and will probably be exempt from flow control standards. The Cedar River is not currently on the list of exempt waterbodies, but our water- shed analysis shows that detention of runoff in the lower reaches of the river is unlikely to have significant impact on flooding or river erosion. The Lower Cedar River Basin and Non - point Pollution Action Plan (Metropolitan King County Council, 1997) recommends a zero detention standard for areas that drain directly to the lower 17 miles of the river. There is growing confidence that wetland restoration sites have potential to provide flow control needed to help mitigation water quantity impact of stormwater. However, before wet- lands can be used in this manner, additional model development is needed to ensure that flow control potential can be adequately quantified. We are actively working with a Department of Ecology stormwater engineer, Foroozan Labib, to acquire the hydrology model components needed to meet this regulatory need. Our research shows that natural features such as geology, topography, and precipitation and human land use dictate the location and extent of alternative mitigation options in a water- shed. Urban and rapidly urbanizing areas tend to have highly degraded natural resources with 12/1/03 -- Page 4 Preliminary Findings: Watershed Characterization I-405 North Renton extensive encroachment that often precludes a potential sites consideration as a viable alter- native mitigation area. These are also the areas where alternative mitigation is often needed most. Specific Findings Three distinct potential mitigation site lists are presented here. Appendix A identifies sites that have the greatest potential to help mitigate stormwater flow control needs and maximize environmental benefit within each of the six stormwater mitigation areas. Appendix B identi- fies wetland and riparian sites that have potential to mitigate wetland and habitat impacts and maximize environmental benefits in each of the six conservative natural resource areas as well as mitigating project impacts and maximizing environmental benefits within the inclu- sive project study area. Potential mitigation opportunities for the study area were identified regardless of whether a specific mitigation need currently exists. This decision was made to ensure that information is available if an unanticipated mitigation need is identified later in the permitting process. In addition, this information can also be used to help meet the mitigation needs of future trans- portation projects within the same mitigation area. The following preliminary findings focus on opportunities to provide stormwater flow con- trol but also provide candidate sites for mitigating wetland and habitat impacts. Coal Creek Coal Creek is a watershed with few opportunities for wetland and riparian restoration due to its geology, topography, and land use. Alternative stormwater flow control opportunities are restricted to stormwater retrofits for developed areas that discharge untreated stormwater to streams. Riparian restoration opportunities are few for this watershed and are restricted to mine tailing areas that are the source of substantial fine sediment problems. Substantial ef- forts have been made by local governments to stabilize these areas with natural vegetation, with limited success. This is a core problem area for the watershed that, if restored, would have a measurable natural resource benefit to the system. Technical feasibility would need to be evaluated carefully. Lakehurst Lakehurst is a narrow area consisting of a number of small catchments that drain to Lake Washington. Alternative stormwater flow control opportunities are restricted to one small wetland area and one large stormwater retrofit area. May Creek May Creek watershed provides a good balance of wetland, riparian, and stormwater retrofit areas for consideration when seeking alternative mitigation options. Kennydale Kennydale is another small catchment area draining directly to Lake Washington. Only one potential wetland restoration site exists within this area that has potential to help provide stormwater flow control and/or mitigate wetland or habitat impacts. 12/1/03 -- Page 5 Preliminary Findings: Watershed Characterization I-405 North Renton North Renton/John's Creek No alternative wetland, riparian, or floodplain restoration options exist within this mitigation area. However, three stormwater retrofit areas exist upslope to the I-405 project that have substantial potential to provide needed stormwater flow control. Cedar River The Cedar River is a major river system that has experienced substantial flow path alteration in its lower reach and flow control from a large dam higher in the watershed. One disappoint- ing finding is the lack of candidate sites for restoring decoupled/diked floodplain areas. While small decoupled floodplain areas exist further upstream, none exist within a reason- able proximity of I-405 to provide substantial natural resource benefits. However, aside from the floodplain area, a good balance of wetland, riparian, and stormwater retrofit options exist to help meet project mitigation needs for this watershed. Limitations Of Data All wetland sites identified as having potential to provide stormwater flow control will re- quire further modeling to quantify the flow control potential of the site. Model feasibility testing is in process for wetlands W62 and W75. All wetland and stormwater retrofit candidate mitigation sites on the stormwater mitigation list have been photo interpreted and have had one site visit to verify initial assumptions. Site visits varied from windshield surveys to walking the entire site and collecting hydric soils data. Candidate wetland and riparian areas for natural resource mitigation that are not also on the stormwater mitigation list have not been field verified. We are developing individual site cost estimates for acquisition and restoration, using a com- bination of estimates of site value and estimates of the costs to modify the sites to meet the mitigation needs. In addition, we completed a preliminary assessment of environmental and social functions that each potential mitigation site could provide if it were restored. We will use this information to assist in conceptually validating or refuting the assumption that water- shed characterization has potential to increase environmental benefit and reduce cost when compared to conventional within right-of-way mitigation options. Appendix B contains a list of potential mitigation sites for natural resource impacts, which are based solely on photo interpretation. These will require initial field verification prior to being listed as viable mitigation options. In places such as the May Valley wetland/riparian complex, considerable overlap exists between wetland and riparian restoration sites. When wetland and riparian sites overlap, wetland restoration is prioritized ahead of riparian restora- tion because the site was historically a wetland. Completing riparian restoration of a drained/ditched stream channel in a historic wetland site will most likely preclude wetland restoration in the future and should be avoided. Ranking criteria for prioritizing wetland, riparian, and floodplain sites for natural resource mitigation needs is in the early stages of development and will, most likely, change in the final report document. Two of the needed datasets are still in development. 12/1/03 -- Page 6 Preliminary Findings: Watershed Characterization I-405 North Renton Next Steps • Test sensitivity of HSPF model that quantifies flow control potential of two potential wetland restoration sites, W75 and W62 • Integrate wetland flow control model into the Western Washington Stormwater Model and WSDOT's MGS Flood Model (pending a favorable outcome of HSPF model sensitivity assessment) • Complete ranking of natural resource mitigation sites • Revise watershed characterization methods document to reflect advances made in do- ing the I-405 North Renton project • Complete cost estimate and environmental benefit estimate; compare these with costs and environmental benefits of conventional mitigation • Write watershed characterization report for I-405 North Renton by December 31, 2003 12/1/03 -- Page 7 Appendix A: Priority Slurmwaler Miligaliun Siles (I lt3W03) Listing of Aable miligation xitex by mitigation urea Coe] Creek Mitigation Am Polenlial Miligaliun Needs: Smrmwa- 5.9 ocre-fat of m,"ge required Welland: Maximum impact - 0.2 acros; extimale of need wish mti-- 0.346 Riparian: None I.akehurrl/Ixke Washington Miligaliun Area Polenliul Miligaliun Needs: Slormw — 27.3 w n,fmt u(xanuge rcyuimd Wedand: Maximum impuce, - 5.8 acres; estimate of need wish ratio., - 11-17.5 acres Riparian: Muimnm impact, - 2.1 acre,; caf—. of need - 1 acre May Creek Miligaliun Area Polmlla1 Miligaliun Needs: Sm wamr: 100A ac e-feeof unmge required WeOxnd: Maximum imp.. - 1.3 ocre,; —imu¢ of need with mhos - 24 ages Riparan: Maximum impact., - 0.7 acres; a.,limate of —d - 0.5 acre Kennydale Mltigalbn Area Putemial Mldgallon Needs: $mrmwaler.

I promised to send you our preliminary results when they became available, and now they are. This is a temporary link - if you try it and the files are gone, tell me and I can easily put them back. Our agency "flushes" the FTP site occasionally. At the link below, you should see a file list of seven files: ftp://ftp.wsdot.wa.gov/incoming/405 Watershed/prelim rept/ <ftp://ftp.wsdot.wa.gov/incoming/405 Watershed/prelim rept/> "405_prelim inary_resu Its. pdf ' is the narrative report. Note: The file is designed for reading online in Acrobat Reader, and will NOT PRINT WELL. To view the appendices conveniently you'll need to rotate the pages using the rotate tool on the Acrobat toolbar, and also you'll need to zoom in using the zoom tool on the toolbar, or the zoom control in the lower left-hand corner of the window. Yes, there's a lot of data there and it comes up small! You will notice this is a high-level, preliminary report. Details on our methods, etc. should become available soon after Jan. 1, 2004. The other 6 files are graphics files (.jpg) of maps of the six catchments we use for the study. These include sites identified and listed in the appendices. These maps have the street grid (and some other features) in enough detail to make identification of the sites fairly easy. As always, thanks for all the help! Feel free to pass this update on as you see fit. Call or e-mail if you want to know more, or if you want anyone to be added to this list. I'll send another update when the final reports become available. We have been speaking to various groups on our methods and our preliminary findings, and will be able to do so again once we pass the final report hurdle! So if you'd like a chance to talk face to face, give us a yell. Tim Hilliard Contacts: Richard A. Gersib, Watershed Program Manager ("big picture") Environmental Services, WSDOT From: Ronald Straka To: Christian Munter Date: 12/1/03 8:12AM Subject: Fwd: 1-405 WSDOT Coordination Chris, here is some information on the City's internal 1-405 Coordination structure and coordination with WSDOT. Please put on your calander for next year the City Design Team meetings (2nd Wednesday of every month). >>> Nick Afzali 11/26/03 02:48PM >>> This e-mail concerns the City's on -going coordination with WSDOT regarding the 1-405 improvement project. Please find attached two organizational charts agreed upon by Department Administrators (Gregg, Alex, Dennis), Jay Covington and the Mayor, that paint the picture of how the City and WSDOT will coordinate with regards to 1-405. Central to this structure are monthly internal City Design Team meetings followed by monthly Renton/WSDOT meetings. A We are planning the City Design Team meetings for the second Wednesday of every month, 1:30-3:OOpm B. We are planning the Renton/WSDOT meetings for the third Wednesday of every month, 1:30-3:OOpm In the near future, Transportation Division administrative staff will be scheduling these meetings on everyone's calendar for all of 2004. The purpose of the City Design Team is, in coordination with WSDOT, to assess 1-405 design impacts to the City and to develop design recommendations/solutions. The internal City Design Team meeting will enable city staff to resolve and clarify the City's position regarding 1-405 issues before meeting with WSDOT the following week. You (or your designated staff) are encouraged to attend the City Design Team meeting, whereas your attendance at the meetings with WSDOT will be more at your option. We do recognize, though, that the topics of discussion which will come up throughout the 1-405 project are numerous, and therefore we will e-mail meeting agendas in advance of the meetings, for you to determine your level of interest. We will also include the minutes from the previous meeting and any other relevant attachments. Additionally, as shown in the attached "City of Renton 1-405 Improvements Coordination" chart, task forces will meet independently regarding specific design issues and will report in to the City Design team meetings. If you have any questions, please let me know. Thanks.

WATER UTILITY: Impact to the City of Renton's existing drinking water wells and water treatment facilities The City of Renton relies on groundwater for over 90% of its water supply. Groundwater is withdrawn from the Cedar River aquifer by six existing drinking water supply wells. This aquifer has been designated a sole source aquifer by the U.S. EPA. The six wells, a fluoridation facility, and a corrosion control facility are all located along 1-405 between the Cedar River and the intersection of I-405 and SR 169 (see attached as-builts). These wells are capable of producing 18 million gallons of water per day. The construction of the proposed I-405 North Renton Project as shown on the preliminary plan (sheet 1 of 8) dated September 17, 2003 will have a significant environmental impact to the City's drinking water supply. In particular, the proposed northbound off -ramp from I-405 to SR 169 will cut through the City's drinking water wells and water treatment facilities. This new alignment will require the relocation and replacement of the City's wells and treatment facilities. The relocation of the City's wells and facilities will require a significant amount of environmental studies — including a potential Environmental Impact Statement. If the relocation of the wells is considered, a feasibility study and detailed hydro -geologic investigation must be done to determine not only if the new wells can be constructed, but also if they can provide a reliable supply of water meeting state and federal drinking water quality standards. Additional water treatment facilities (i.e.: new water filtration plant) may be required to comply with current water quality standards adopted by the Department of Health. Purchase or condemnation of properties including City parks will be needed for the new wells and facilities. Test wells must be dug and pump tested to ensure adequate yield. The Department of Ecology may not allow the new wells to be dug near the Cedar River due to potential impacts to instream flow. Transfer of water rights will need to be approved by Ecology. The -Department -of Ecology and the-Muckleshoot-tr-ibe-can-require-new mitigation -measures -if thetest wells show an impact to river flows during pumping. The new wells and water treatment facilities must be constructed and be operational for several years to ensure a reliable supply before the existing wells can be abandoned. This entire process may take up to ten years or more. 1055 South Grady Way - Renton, Washington 98055 ® This paper contains 50 % recycled material, 30% post consumer RENTON AHEAD OF THE CURVE I-405 North Renton Project October 27, 2003 Page 2 The limited program -level groundwater analysis shown in section 3.5.2.2 Water Resources/Groundwater of the Project NEPA/SEPA Preliminary Final EIS and Final Preliminary Section 4(f) Evaluation dated March 2002, including the referenced study I-405 Corridor Program Draft Groundwater Resources Expertise Report by CH2M Hill, 200 1 b, does not provide sufficient information to determine the impact of the I-405 North Renton Project on the quantity and quality of groundwater to the City's wells. The impact to water quality and water quantity from construction of structures across the well field must be thoroughly studied and evaluated. The construction of a fly -over ramp within the sanitary control area, one hundred feet radius, will put the City water supply at risk for contamination and violates the provisions in the WAC 246-290-135 on source water protection. The construction of support pilings may affect the flow of water to the wells. Any decrease in the quantity of water produced by the wells or any degradation of well water quality resulting from the construction and operation of the I-405 improvements must be investigated and remediated at WSDOT's expense. Remediation may include the construction of replacement well(s). Chemicals used for the construction of the support structures could contaminate the water supply. Adequate vertical clearance, at least 50 feet above the existing well building roofs, must be provided for access by well drilling rigs, so the wells can be redeveloped in the future. Access and clearance for cranes must be provided to remove the pumps and columns for maintenance. Access for chemical delivery trucks must be maintained. Surface Water Management Standards (Renton Municipal Code RMC 4-6-030E2 and 3): The following are prohibited in Zone I of the City's Aquifer Protection Area (APA): Biofiltration, retention/detention ponds, :infiltration, and drainage ditches and channels. New pipes shall meet pipeline specifications in 4-3-0505. Impervious surfaces shall be provided for areas subject to vehicular use or storage of chemicals. Discharge of runoff from more than one acre of impervious surface may require installation of a wetvault'1.5 times the usual size. Surface water runoff during construction _activities and operation phases of the project must not be allowed to infiltrate in Zone 1, the one-year capture.zone, of the City's aquifer protection area (APA). Runoff should be collected irr lined detention ponds, treated, and diverted to surface water. Adequate detention volume should be provided to contain a hazardous material spill until it can be removed from the pond. Bridge over the Cedar River: No bridge supports are to be installed in the riverbed to prevent compromise of the silt seal in the river. Construction Activity Standards (RMC 4-4-03007): Standards shall be followed if, during construction, more than 20 gallons of hazardous materials will be stored on site or vehicles will be fueled on site. Fill Source Statement (RMC 4-4-060L4): A fill source statement is required if more than 50 cubic yards of fill material will be imported to the project site.

Due to the existing active recreation uses including an outdoor aquatic facility and sunbathing area and soccer field, there shall be no shade extending more than 50' southwest from the existing northeast park property line along the Maple Valley Highway (line drawn parallel to the existing park property line). Any shade in the park area will need to be mitigated. In addition, any shade extending into the aquatic facility/sunbathing area and field area will need to be mitigated by also taking into account the loss of revenue from a decrease in facility use caused by the shade. 2. Due to the existing active recreation uses, including an outdoor aquatic facility/sunbathing area and soccer field, noise impacts will need to be mitigated with a sound barrier. 3. Additional information regarding the elevation of the proposed ramp system is necessary in order to determine potential additional impacts to the water slide amenities. It appears the slides may be at the same elevation as the ramps necessitating an increase in noise and air quality mitigation. 4. Loss of usable parkland and air space will need to be replaced in kind within the Cedar River Trail Corridor system located between Lake Washington and Ron Regis Park. 5. Rubber particle/residue from the adjacent ramps into the park area and especially the pool area will need to be mitigated. This residue will likely cause increased deterioration to the pool facility. 6. The Parks Division will not accept any loss of park maintenance facility yard area or maintenance building structures due to the existing limited capacity. Any loss of space will require relocation of the Parks maintenance facility including property acquisition and facility development. 7. Two access points to the park must be maintained at all times and must be able to accommodate ladder trucks, fire engines, aid cars, maintenance vehicles, and park users (including trestle area). Access from the Maple Valley Highway and one access from Houser Way need to be maintained. 8. Trail access from Cedar River Park over the river to the Narco property must be maintained. Any impacts will need to be mitigated. 9. Shadow effects from I-405: Due to the existing active recreation uses and landscape amenities, encroachment of shade into the park area will need to be mitigated. Shade encroachment inhibits plant and turf growth and rejuvenation, thereby limiting the scheduled use of field time. 10. Damaged and/or removed landscaping and irrigation will need to be replaced in order to maintain the park setting. 11. The four -foot -diameter (approximate) Big Leaf Maple (Acer macrophyllum) east of 1-405 will need to be evaluated and appraised by a certified arborist. If removal is required, the City will require monetary reimbursement for the appraised replacement value. 12. Prior to construction, a certified arborist will be required to evaluate all trees with a tree canopy extending into any proposed construction limits. A certified arborist report will be required for each tree identifying recommendations for tree protection, special pruning practices, etc. to be utilized during the construction phase(s).

The City will require a certified arborist perform all tree root pruning, limb removal, limb pruning, tree spadework, etc. 14. The City will require a licensed landscape contractor to install all landscape elements including: plant materials, sod/seed, topsoil and irrigation. 15. There shall be no net loss of parking in Cedar River Park. Any loss will need to be replaced. Any loss of parkland and loss of usable parkland through the creation of replacement parking will need to be mitigated through in kind replacement within the Cedar River Trail Corridor system located between Lake Washington and Ron Regis Park. 16. The proposed decorative noise wall along SR 169 (as part of the SR 169 project) will need to be preserved and protected. If the wall is removed and replaced, the replacement wall will require the same artwork incorporated into the forming process. 17. New noise walls constructed as part of this project and facing park property need to incorporate architectural elements consistent with existing park and recreational architectural features. Narco Property 1. Primary vehicular access, emergency access (police and fire) and trail access to the Narco Property from Mill Avenue South needs to be maintained at all times. Improvements including new clear span bridges need to ensure vehicular, emergency and trail access from Mill Avenue to the Narco Property. Access must meet City road and bicycle standards. 2. Loss of usable parkland and air space will need to be replaced in kind within the Cedar River Trail Corridor system located between Lake Washington and Ron Regis Park. 3. Trail access from Cedar River Park over the river to the Narco property must be maintained. Any impacts will need to be mitigated. Liberty Park 1. Bicycle/pedestrian access from the Cedar River. Trail to Cedar River Park and over to Liberty Park must be maintained, as this is part of a regional trail system. 2. Prior to construction, a certified arborist will be required to evaluate all trees with a tree canopy extending into any proposed construction limits, including but not limited to trees on Bronson Way and Houser Way. A certified arborist 'report will be required for each tree identifying recommendations for tree protection, special pruning practices, etc. to be utilized during the construction phase(s). The oak trees on Bronson Way will need to be .evaluated and appraised by a certified arborist if removal is required. The City will require monetary reimbursement for the appraised replacement value. 4. The City will require a certified arborist perform all tree root pruning, limb removal, limb pruning, tree spadework, etc. HAFile Sys\TRP -Transportation Planning & Programming\TRP-10 • Transportation Planning Projects\WSDOT 1-405\N Rmton\N Renton EA City Comments.dockor 1-405 North Renton Project October 27, 2003 Page 5 5. The City will require a licensed landscape contractor to install all landscape elements including: plant materials, sod/seed, topsoil and irrigation. 6. There shall be no net loss of parking. Any loss will need to be replaced. Any loss of parkland and loss of usable parkland through the creation of replacement parking will need to be mitigated through in kind replacement within the Cedar River Trail Corridor system located between Lake Washington and Ron Regis Park. 7. The close proximity of the proposed relocated Houser Way to the skate park creates safety and access concerns that need to be addressed. Any solution must provide safe access from Houser Way to the skate park (for skating) and around the skate park (between the well house building and the skate park) for pedestrian access. New noise walls constructed as part of this project and facing park property, need to incorporate architectural elements consistent with existing park and recreational architectural features. 9. Loss of usable parkland and air space will need to be replaced in kind within the Cedar River Trail Corridor system. May Creek 1. Loss of parkland and air space will need to be replaced in kind within the May Creek Trail Corridor. 2. Loss of vegetation will require re -vegetation with native plant materials. 3. Additional information is required regarding the installation of a sound barrier system in this section of the corridor due to the steep topography.. A constructed sound barrier may require an increased loss of parkland and existing native vegetation - all of which .will need to be replaced. Wells and Parks Summary Regarding the constraints near Liberty Park and Cedar River Park due to these parks and the City of Renton's well field, thorough technical comments are provided in the preceding. However, to summarize the City's position: ■ The City's wells cannot be relocated and must be avoided. ■ Impacts to the parks should be minimized. Given the first two positions, an alignment and interchange configuration should be pursued to determine if it is possible to provide for future flyover ramps that will allow direct access to North Renton. STORAIWATER: The project should provide water quantity control (detention) and water quality improvements for all existing and proposed right-of-way improvements. The quantity and quality controls should be designed __in_acc_ordance_with_the_Washington_State_Depar_tment_of EcoloU Stor-mwater-Management-Manual for — Western Washington or equivalent standards. If WSDOT storm systems currently discharge or are proposed to discharge to City storm systems, the downstream system capacities should be analyzed and off -site improvements made as part of the project as needed. Water quality and quantity impacts should be mitigated such that there is no impact immediately downstream of the project. Watershed based H:\FileSys\TRP- Transportation Planning & ProgrammingWRP-10 -Transportation Planning Projccts\WSDOT I-405W RmtonW Renton EA City Commrnts.doc\cor 1-405 North Renton Project October 27, 2003 Page 6 mitigation will need to show that there are no temporary or long-term impacts due to increased peak rate and volume of runoff, along with changed water quality, downstream of the project even if upstream off - site mitigation is proposed by the project. If off -site watershed mitigation cannot fully mitigate the quantity and quality impacts to the downstream systems (stream or constructed storm systems), then downstream mitigation will also be required. WETLANDS: At a minimum, the project should be held to a "no net loss" of wetland area, function, and value. Replacement ratios for wetland mitigation should, at a minimum, satisfy Renton's wetland replacement ratios for wetland impacts in Renton. Department of Ecology's or Army Corps of Engineers' replacement ratios should be acceptable if they are equal to or more stringent than Renton's. Wetland mitigation should be done in the same basin and as close as possible to where the impact occurs. WSDOT should establish wetland mitigation banks in the basins where wetlands will be impacted by the project and establish the wetland banks as required by the State's Wetland Mitigation Banking rule. This will ensure that the created wetlands are established, and have the same function and value as the wetland that is to be impacted, prior to the wetland being filled by the project. STREAM BUFFERS/FISH HABITAT: The project should provide mitigation to provide for "no net losses" of stream buffer area, function, and value. In addition, the project's impacts to fish habitat (spawning, rearing, and passage) should be held to the same standard. Replacement ratios (2:1) for impacts to stream buffers and fish habitat should be required. Mitigation should be incorporated at the location of the impact to the maximum degree possible, but the additional mitigation could be done offsite within the same basin or watershed. A mitigation fund could be established for acquisition, restoration, or enhancement of stream buffer and/or prime fish habitat sites that have been determined to be beneficial to improving salmon habitat. The project should not only mitigate for the action impacts but should have a restoration element to offset prior impacts and the fact that mitigation benefits are not immediately achieved, especially when it comes to stream buffers. Any existing culverts or other stream crossing structures that are barriers or restrictions to fish passage should be replaced with new structures that don't prevent or restrict fish passage. Tributary 0283, presently located near the intersection of. NE 43rd Street and Jones Avenue NE, historically was a tributary to May Creek. Through the decades, with the improvements to roads and highways, May Creek and this small tributary have been rerouted and disconnected. Tributary 0283 is a source of potential flooding over NE 43rd Street without annual removal of sediments at the culvert crossing of NE 43rd Street. With the reconstruction of the NE 44th Street interchange, the potential for reconnecting Tributary 0283 with May Creek exists. One method for doing this is replacing the culverts under 1-405 with open channels as proposed for Coal Creek and connecting Tributary 0283 with the ditches along Lake Washington Boulevard, which convey water to May Creek. FLOODPLAINS: The project should be required to provide compensatory storage for filling of any floodplain. A "zero rise" to the floodway standard should be applied to the project. The project is also required to comply with all FEMA and Nation Flood Insurance Program (NFIP) standards, since Federal funding will be used. No encroachment into the floodplain should be allowed, unless through a hydraulic analysis, it can be demonstrated that the zero rise standard can be achieved. The hydraulic analysis should be based upon future land use condition 100-year flood flows. All bridge crossings of Cedar River and May Creek should be the full span of the 100-year floodplain, i.e. no piers, abutments, etc. should be located in the HAFile Sys\TRP - Transportation Planning & Programming\TRP-10 - Transportation Planning Projects%WSDOT 1-405W Renton\N Renton EA City Comments.dockor 1-405 North Renton Project October 27, 2003 Page 7 100-year floodplain. New bridge low chord elevations (bottom of the bridge) should be set above the future land use condition 100-year flood elevation by a minimum of three feet, or higher on streams or rivers with the potential for large debris flows. Per the Flood Insurance Mapping Study, April 2003 prepared by Northwest Hydraulic Consultants, the pedestrian bridge under 1-405 experiences partial or complete pressure flow during the 100- year flood event. It might be possible to remedy this situation by raising or reconstructing the pedestrian bridge coincidentally with the proposed 1-405 improvements at the Cedar River crossing. STORMWATER UTILITIES: The 1-405 right-of-way creates a major barrier to utility services. Regarding stormwater, a hydrologic and hydraulic analysis of all existing and proposed culverts and storm systems that cross I-405 should be performed to verify that the systems have adequate capacity to convey the 100-year/24-hour storm event for future land use conditions. If the analysis indicates that the system has insufficient capacity, then it should be replaced with a properly sized facility. This is needed to ensure that adequate stormwater conveyance can be provided across the I-405 corridor and that the project will not create upstream drainage problems. Any City -owned structures that have to be relocated or are impacted by the project should be fully coordinated with the City as to sizing and relocation — all at no cost to the City. A review of the need for potential new storm system crossings should also be conducted in coordination with the City of Renton Surface Water Utility to address the barrier problem that I-405 presents to the natural drainage and the ability to provide storm drainage service to areas upstream of I-405. The following is a list of 1-405 storm crossings from the City's inventory maps, not to be construed as a definitive list (see attached inventory maps): . • At SR-169 (Maple Valley Highway) • South of NE 6'h Street • At North 8'h Street • Midway between NE Park Drive and North 81h Street • At NE Park Drive (runoff from NE Park Drive) • At NE Park Drive (runoff from NE_ of 1-405/NE Park Drive intersection) • At NE 27`h Court • North of NE 44`h Street SHORELINES: The project should comply with the currently adopted Washington State Department of Ecology Shoreline Management Guidelines and City adopted Master Shoreline Program regulations. TRANSPORTATION: City Arterials and Local Streets Impacts to traffic patterns and volumes on City arterials and local streets need to be identified and mitigated. These impacts potentially include, but are not limited to: ■ The cul-de-sac of Houser, Meadow and Factory Avenues at Bronson Way; ■ The additional capacity needs on Mill Avenue, the Bronson Way bridge and the Logan Avenue bridge over the Cedar River; ■ Traffic pattern revisions on Sunset Boulevard at the SR 169/North 3Td Street interchange; HAFile Sys\TRP - Transponation Planning & Programming\TRP-10 - Transportation Planning Projects\WSDOT 1.405\N Renton\N Renton EA City Comments.doc\cor 1-405 North Renton Project October 27, 2003 Page 8 Additional traffic signals or traffic signal revisions, such as on the Maple Valley Highway and NE 3rd Street; and, ■ The connection of Houser Way North to the SR 169 interchange, due to the loss of the Houser Way Tunnel. Neighborhoods and Businesses Impacts to traffic through neighborhoods need to be identified and mitigated. Neighborhoods potentially impacted include the downtown Renton Central Business District (CBD), the north Renton residential neighborhood, and the Highlands neighborhood (due to revised Sunset Boulevard). Impacts, such as access and traffic patterns, to local businesses need to be identified and mitigated. Potentially impacted businesses include those located on Sunset Boulevard, Bronson Way North, Maple Valley Highway and Main Avenue South. Due to the proposed split -diamond interchange configuration at SR 169/North 3rd Street, pedestrian and bicycle connectivity between North 3rd Street and Maple Valley Highway need to be identified. Traffic Modeling and Simulation Traffic modeling and simulation should be conducted using appropriate tools in order to fully identify and understand the impacts on local arterials, streets and freeway interchanges. Detailed discussion regarding traffic modeling, such as intersection capacity analysis, is being coordinated between the City and WSDOT through separate correspondence. It is anticipated that in the near future the Renton City Council will be making decisions regarding the North Renton Boeing area and potential Comprehensive Plan amendments. A Draft Environmental Impact Statement (DEIS) was issued in July 2003 regarding the Boeing proposal to rezone portions of their North Renton property as a result of their "move -to -the -lake". As identified in the DEIS, traffic and land use changes due to the redevelopment of the North Renton Boeing property need to be included in the I-405 future traffic modeling analysis: The 'baseline forecast, will not include the Boeing Land Use Scenarios. The North Renton Boeing Redevelopment DEIS traffic analysis indicates that the proposed revisions to the SR 169 interchange will operate over -capacity. The performance of this interchange needs to be validated. The North Renton Boeing DEIS identifies a capacity need in the Park Avenue interchange, eastbound to northbound traffic. The capacity needs of this interchange should be analyzed. For example, it should be determined if the eastbound to northbound loop ramp should be retained in the future design. It is proposed to eliminate the I-405 ramps from Sunset Blvd. Sunset Boulevard will go over or under I- 405 and connect into the North Renton neighborhood local street system. It is the City's preference to have Sunset Boulevard go under I-405, if possible. Traffic modeling should analyze the traffic impacts due to this reconfiguration of Sunset Boulevard. HAFile Sys\TRP - Transportation Planning $ Programming\TRP-10 - Transportation Planning Projects\WSDOT 1-405W Renton\N Renton EA City Conan-ts.dockor I-405 North Renton Project October 27, 2003 Page 9 Renton Hill Access The September 17, 2003 Preliminary Plans show the two existing access overpasses (Cedar Avenue South and Renton Avenue South) being combined into one access, with the overpass on the Renton Avenue South alignment. Although south of the Cedar River, due to its close proximity to the North Renton project limits, we offer the following perspectives regarding access to Renton Hill. 1. A second access to Renton Hill needs to be provided. 2. Any impacts due to this second access need to be minimized and mitigated. The second access should be cost effective. South Renton funds saved with this secondary access alternative will then be available for other sections of South Renton. WSDOT proposed several options for a second access to Renton Hill. These options include extending either Grant Avenue South or Cedar Avenue South, south into the Benson Hill neighborhood; connect either Mill Avenue South or South 7'h Street across I-405 to South Grady Way between City Hall and Sam's Club; and, extend Mill Avenue South northeast, down the hill, in order to utilize the existing Narco property access under the I-405 Cedar River bridge. WSDOT and the City will continue to develop a preferred alternative to provide this second access. PACCAR There are several potential impacts to the PACCAR property that need to be identified and mitigated: ■ The North 8th Street direct access ramp may have impacts to the PACCAR property on the south side of the street; ■ The relocation of Houser Way North to its former location across the PACCAR property; ■ The potential extension of Sunset Boulevard to the west, across PACCAR property to North 51h Street. ECONOMIC DEVELOPMENT, NEIGHBORHOODS, and STRATEGIC PLANNING 1. While this may already be addressed, please accept this reminder that the North 81h Street HOV direct access ramp should allow ramp traffic to access the north leg of Garden Avenue, both in where the ramp lands and through signalization to allow for safe turning movements. 2. To maintain the future viability of Houser Way, potential connections should be examined so that Houser Way between Park Avenue and Bronson Way can function as a frontage road. 3. Similarly, the North Renton I-405 Environmental Assessment should consider options for Sunset Boulevard NE to have a more direct link to I-405. 4. The Park Avenue Interchange northbound exit ramp should be located to allow enough room for an eastbound to northbound loop ramp. City of Renton forecasts indicate that this loop ramp would be necessary even under baseline land use conditions. Earlier NE 44 h Street interchange designs showed an eastbound to northbound loop ramp. The northbound exit ramp should be located far enough east to allow room for this potential loop ramp.

Welcome and Meeting Objective (Christina Martinez): The objective of the agency scoping meeting was to present the North Renton Project to agencies with jurisdiction and to identify local concerns and issues. Issues identified at these meetings will be incorporated into the environmental and design processes. Public concerns and issues will be identified later in the day at a public scoping meeting at Kennydale Elementary School. Information gathered during this process will be documented in a Scoping Report. Introductions (Christina Martinez): Christina introduced the Environmental Management Team Members (EMT) including herself, Keith McGowan, Ed Murray, and Tracey McKenzie. The EMT is responsible for the environmental analyses for the project. Christina also introduced the Contract Manager for North Renton, Roland Benito who is responsible for the design aspects of the project. The EMT and the Contract Manager will work closely together to ensure that the project design meets the overall purpose and need as well as minimizes impacts to the environment. Selected Alternative Refinement (Roland Benito): All attendees received an Environmental Overview and aerial maps with the North Renton design overlay. The Environmental Overview summarizes the known environmental issues for the North Renton project area. This information was largely developed as part of the I-405 Corridor Program Final EIS. The aerial maps with the North Renton design overlay were intended to be used as a starting point for discussions regarding the environmental issues. Although these plans are a starting point, it's important to keep in mind that an extensive screening process occurred in order to get that point. A series of design charettes were held with the intent of designing around known environmental constraints. This was an internal process used to get where we are now. As part of this process, the Selected Alternative contained in the I-405 Corridor Program FEIS was refined. The I-405 Corridor Program EIS yielded the Selected Alternative, which is a multi -modal system of approximately 150 projects that were advanced from the more than 300 individual projects that comprised the alternatives studied in the Corridor EIS. We are now conducting the project -level NEPA environmental review necessary to advance implementation of the Selected Alternative. We have identified four geographic sections within which to conduct the project -level evaluations. Our focus today is North Renton, extending from approximately SR 169 near the Cedar River in Renton, north to approximately Coal Creek Parkway in Bellevue. This sections lies within the Cities of Renton, Newcastle, and Bellevue as well as a small portion of King County. The Selected Alternative was a big picture look at the Corridor in its entirety. Splitting the Corridor into sections allows us to take a closer look at the local area concerns and issues. Charettes were conducted in order to refine the design of each section. Many options were evaluated based on criteria including: • The goals, issues, and constraints expressed by the public, local jurisdictions, or other agencies. Meeting the project objectives and implementing the Record of Decision Minimizing environmental impacts Experts in interchange design, roadway design, stormwater design, and context sensitive design were consulted during the evaluation. Nine options were evaluated based on the criteria. Widening options to the east, to the west, and symmetrically were evaluated along with many interchange types. A best fit option fell out as a result of the charettes. The Best Fit option includes a combination of all the widening options. In some areas the roadway would be widened to the west and others to the east or symmetrically. Widening in this fashion limits ROW acquisitions as well as natural resource impacts and allows for staging so that construction can occur without impacting traffic. We are now in the process of refining this "best fit" option and the design you have is just a starting place to give us something to talk about. Design/Build (Roland Benito) The N. Renton project will be a design/build effort. It is critical that we have the resource agency support. This project will be different than the typical design -bid -build efforts in that we will be completing a lower level of design before handing it off to a contractor to finish the design and build the project. There are great benefits in terms of schedule. We are going to rely on the experts from the construction industry to come up with the best design and construction methods for this project. The plan is to provide enough design to be able to answer all the questions that the resource agencies may have. Once they are satisfied we will involve the construction experts. We will provide agencies with all the information they normally receive but we expect the pace to be different. Will the agencies really need 100% design in order to support their decisions? If not, we want to leave some design room for the construction industry so that they can use their knowledge to come up with innovative techniques that will expedite the construction schedule. We want to clear an envelope so that the design builder can take it and use their expertise to implement. We will be holding a Design Build Education program and we would like you to participate. It will help all of us understand what Design/Build is all about. We will be contacting you. Environmental Assessment (Keith McGowan) The I-405 Corridor Program EIS provided the foundation on which the project -level EIS will build. The basis for this is documented in the ROD. The project -level analysis will be based on design details, which include: • limits of right-of-way • edge of pavement • toe of slope, including walls • walls, including retaining walls and noise walls • stormwater facilities, technologies and locations • staging area locations - to the extent known • stream crossing types and span length • changes in impervious surfaces • construction duration, methods and phasing project descriptions - to the extent known Keith mentioned that the EA might look different than what we are accustomed to. It is going to be more "reader friendly" and we plan to have it formatted in a Question and Answer fashion. Discipline Reports are being prepared and will provide all the technical information in support of the EA. The Discipline Reports will be incorporated through reference. We plan to complete the Discipline Reports by late winter/early spring and issue the EA in the Summer 2004 at which time we will hold a Public Hearing. It's expected that the EA will lead to a FONSI. We are confident in taking this approach and we have made extensive progress through the charette efforts in avoiding and reducing impacts. Cooperating Agencies (Christina Martinez) Christina explained that regardless of whether agencies become formal "cooperating" agencies, we will be working in cooperation. Once the Discipline Reports are completed they will be available for agencies review, although formal comments are not anticipated. Permitting Approach (Tracey McKenzie) Tracey explained that the first step in the permitting approach will be to identify all permits. The next step will be to designate whether the I-405 Team, will obtain the permit or if it is more appropriate for Design Builder to obtain the permit. A regulatory analysis will be conducted as part of the environmental review process. The Discipline Reports will provide the basis for this analysis. The analysis will be part of the EA or as an Appendix or a chapter. We expect to prepare draft applications during the time between the EA and the Final EA. Discussion (Roland Benito) Roland Benito presented the project design as agencies referred to the aerial maps. The following table summarizes the main points of discussion with the agencies: Southern project Limits The project begins at the Cedar River, however the plan sheets show more to ensure that the project will fit in with the S. Renton section. Are the two bridges that provide access to Renton Hill apart of the project? (City of Renton) Renton Hill access is not part of the N. Renton project. The two crossings will be addressed as part of the S. Renton project. At this point we can tell you that there is a commitment for maintaining these crossings over 405. 1-405/SR 169 Reconstruct the SR-169 Interchange to a split diamond configuration including N. 3rd Street. The northbound (NB) off and southbound (SB) on ramps from 1-405 to SR 169 would be reconstructed. Provisions will be made for a SB 1-405 to eastbound (EB) SR 169 direct connection ramp and a westbound (WB) SR 169 to NB I-405 direct connection ramp. The decision about whether to recommend these ramps as part of the North Renton Project will be evaluated further based on the results of additional traffic modeling. How many feet will the project encroach into Liberty Park? (Parks Department, City of Renton) As shown on sheet 1 of 8 of the preliminary plans (in the North Renton Project Overview binder), Houser Way would be realigned just to the west of it's current location and end in a cul-de-sac just to the sough of Bronson Way. This may affect park parking and a sliver of the park property at the north east corner. The number of square feet of impact has not yet been calculated. Parking at the parks is an issue (Parks Department, City of Renton) The parks department identified concerns in regard to park encroachment. Parking is a major issue at both parks. There will be parking impacts at Liberty Park near the ball field. Houser Way is wide and if it becomes cul-de-saced we could use some of it to replace the park property impacts. The plan is to cul-de-sac Houser Way. Houser Way is currently one-way to the north. Changes in this area will depend on negotiations with the Railroad. The railroad has 100-feet of ROW. Will there be any Cedar River parkland take at the landing of the direct access connection ramps? (Parks Department, City of Renton) There are issues with the flyover ramps near the Cedar River Park. The idea is to build columns and cantilever the ramps over SR 169 — property acquisitions would be minimized but there may be some shadow effects. This is something that needs to be coordinated with the City parks department Will Cedar River clear span allow for a trail? (Parks Department, City of Renton) The goal here is to clear span almost all water crossings. If piers are in the water we will consider removing them. The goal is to clear span Cedar River and keep enough land area for the trail. There's lots of stuff underneath the bridge and there is a need for maintenance access, access to a new Sports Complex to be built, and access for the trailhead. Both the road and the trail are critical. What are the avoidance alternatives for park impacts? (FHWA) When the Proposed Action affects a park you must look at an avoidance alternative. A stacking alternative has been identified and will be evaluated as an avoidance alternative. Other issues The mainline in this area is constrained by the two parks. The goal was to minimize impacts by widening to the west. We will be talking to the RR to find out if we can realign the tracks. In addition there are water supply facilities on both sides of 405. There are existing buildings right next to the ramp at Cedar Park. Options are to avoid or rebuild. We are wary that 80% of the facility is underground. The area is a Sole Source Aquifer. City of Renton is not in favor of relocating wells. The permitting itself can take up to 5 to 10 years. Also the relocated wells must be in operation for a certain amount of time before you can begin construction. Our planning level design indicates that we could flyover but traffic operations would be compromised since the ramp would have to come back down at SR 169. N. 3rd Street New NB on -and SB off -ramps from I-405 to N. 3rd Street will be constructed to replace the existing movements that occur at Sunset Boulevard (SR 900). This will include providing HOV bypass for the on -ramps and reconstructing the bridge structures. One-way frontage roads NB and SB will be constructed between SR 169 and N. 3rd Street. 1-405/Sunset Boulevard Sunset Boulevard (SR 900) will be reconfigured to an overcrossing with no ramps to and from I-405. Sunset will cross I-405 and connect as a new roadway to Garden Avenue west of I-405. There are several issues related to the reconfiguration of Sunset Boulevard (SR-900). Its important to minimize impacts to businesses, they are so close and not a lot of room. Paccar property is potential hazardous waste issues. Don't want an at -grade crossing at the RR so going underneath 405 does not work. PacCar has development plans. Why can't Sunset Boulevard connect to the local street system to the south of the current design? (City of Renton) If we make a southern turn we will need to re-evaluate. If Sunset Boulevard stays connected to the local street system the traffic problems remain. This is an option however and will be negotiated with the City. N 8th Street Provisions for a direct access HOV ramp will be provided in the I-405 mainline at N. 8th Street. This provision will provide north and south transit/HOV access from I-405 to the west at 8th Street. Will the North Renton design fully cover the Sound Transit Project at N. 8th Street (FTA) Yes, the provisions for a direct access HOV ramp at N. 8th Street will be covered under this EA. This is a Sound Transit project and integrating it into the 405 project will save time and money. You can build N. 8th without impacting existing traffic. This is designed as part of this project. WSDOT to take it on so that there is no need to redo work. The FTA agrees that it should go through one process. 1-405/NE Park Drive The NE Park Drive Interchange will be reconfigured to a diamond interchange, including HOV bypass for the on -ramps and replacing the bridge structure. A new northbound ramp will be provided (ultimate build -out proposal) creating the auxiliary truck -climbing lane. The reconfiguration of the NE Park Drive will add more capacity. The topography is not that great in this area so there will be truck -climbing lanes north of Park over the crest of 301h. The mainline will be widened symmetrically in this area. It's hard to come up with a decent alignment to accommodate a Single -point -urban interchange. The west is fully developed so shift to the east to avoid apartments. Further north still symmetrical and a lot of walls. There are not enough details yet to determine the interchange type. What we show now, however, shows the most footprint. 1-4051N. 30th Street The NE 30th Street Interchange will be reconstructed to accommodate the widened freeway, including HOV bypass for the on -ramps and replacing the bridge structure. Provisions for a direct access HOV ramp will be provided in the I-405 mainline at SE 76th Street. This will provide north and south transit/HOV access from I-405 to the west and east at 76th Street. Reconstructing the NE ) Street Interchange will provide a better connection between the community on the east and the community on the west. The design is intended to minimize impacts to May Creek and the Kennydale neighborhood. . Because there are steep slopes down to the creek, the widening of 405 would be cantilevered on the east side. Near May Creek the alignment is to the west. The goal is to balance the need to maintain street access and to avoid impacts to the creek. The cantilever may have a shadow impact on the slopes. Noise — context sensitive design issues. With berms you need more property but you can have landscaping. Right now you have 405, noise wall, house. Landscaped berm might be an improvement. Are alignment decisions considering the impact between partial takes and full takes. Some residences may prefer one over the other. Property impacts are an issue — half -takes cause greater concern. There is room to negotiate, when it comes to taking only a piece of the property or taking the whole house. People can make that choice there will be flexibility. There may be alignment refinements, based on conversations with residences. The Kennydale School District is going to re -build the existing Kennydale School. Is this being considered in terms of alignment within this area? Avoiding the Kennydale School was a major issue in this area. Schools have a square footage requirement and the school currently does not meet requirements, so any property acquired from the school would exacerbate the problem. Renton School district will be rebuilding Kennydale School and this will be consideration. There are no plans yet. The plan is to temporarily locate students at Newcastle school while Kennydale is rebuilt. 1-405/NE 44th Street The NE 44th Street Interchange will be reconstructed to accommodate the widened freeway, including added capacity on NE 44th Street and the ramps as well as HOV bypass for the on -ramps and replacement of the bridge structure. The NE 441h Street Interchange is based on the design proposed for the Port Quendall design. Widening the mainline is symmetrical to NE 441h. Boeing Redevelopment plan analysis shows need for loop ramps. Loop ramps in SE quadrant of 44th and Park. An east loop ramp would require us to push out the currently designed interchange. Ramp locations to the west but also minimize residences. Widen existing structure there may be shadowing —widening because ramps have to span creek ... tried to carry ramps as far as they could. North of 441h widen to the east. Bike path west of 405 restricted by the Railroad ROW. What are the impacts to May Creek? (King County DOT) We plan to clear span May Creek. We've looked at it and it appears to be pretty easy. Also, the facility has been aligned to avoid May Creek park. SE 76th Street Provisions for a direct access HOV ramp will be provided in the I-405 mainline at SE 76th Street. This will provide north and south transit/HOV access from I-405 to the west and east at 76th Street. I-405 widening across May Creek, possibly by cantilevering or other engineered support system to span the channel without adding piers. Provisions for a direct access HOV ramp at SE 76`h Street. Accommodate for future access from the west for future land uses. Accommodate future land uses at Quendall, Baxter, and Genie. The mainline will be widened to the east and Lake Washington Blvd will be relocated. Widening to the east impacts property. Widening to the east in this area. If you widen to the west you start affecting access to those lakefront properties. Lots of walls in this area and drainage issues. What is the plume shown on Sheet 6? (King County DOT) The plume on the aerial may indicate erosion. There has been a lot of development going on to the east. There's a lot of sedimentation and cross -culverts. This is a problem location We will make sure that stormwater facilities are in place early to avoid erosion and sedimentation during construction. 112th Avenue SE The I I2th Avenue SE Interchange will be relocated to the south to accommodate the widened freeway and construction of a flyer stop serving the park -and -ride at I I2th Avenue SE. Construction includes HOV bypass for the on -ramps and replacing the bridge structure. A transit flyer stop at 112th Avenue SE will be constructed in the I-405 median with pedestrian access from the median to the existing park -and -ride lot east of I-405. The park -and -ride lot will be modified to accommodate the widened freeway. Construction of an in -line station serving the park -and -ride structure at 112`h Avenue SE. The park -and -ride will be three-story structure which would provide more capacity with minimal new ROW. Multistory also allows for a nice in -line station. Relocating to the south works because you have to rebuild the interchange for the mainline widening anyway. Need to maintain access to the residences to the west. 1-405/Coal Creek Parkway The Coal Creek Parkway Interchange will be reconstructed to accommodate the widened freeway and construction of ramp improvements to and from I-90. The ramps at Coal Creek Pkwy will include HOV bypass for the on -ramps and replacement of the bridge structure. Reconstruction of the Coal Creek Parkway Interchange and ramp improvements to and from I-90. The design shows a widening to the east to avoid the RR tracks and the neighborhoods. ROW to the east there will be big cuts and high walls 30 to 40-feet. The ramps will be reconstructed and Coal Creek which is currently in a box culvert will be daylighted. The culvert is currently 470-feet long. There will be environmental benefits and we will pursue that and see how the agencies feel about it. Need support in order to implement this idea. Other Questions: What were the 9 options? What are the phasing concepts? (King County) During the charrette process, local and national engineering experts developed design ideas for the I-405 North Renton project. Some ideas were determined to be fatally - flawed or dropped off the table due to unacceptable traffic, social, or environmental issues. This information is being documented in a project screening report. At this time, there are no specific phasing concepts for implementing the I-405 North Renton project. Project phasing will largely be dependent upon project funding. Are we going above and beyond the typical mitigation efforts? (King County DNR) We hope to initiate early environmental enhancement, restoration or creation projects. We say "early" because we want these environmental investments to occur prior to transportation project construction so that the environmental benefits are realized before the impacts occur. Also, we are taking a watershed based approach to identify locations where the environmental investment makes the most sense for overall watershed recovery. In a sense we are going above and beyond typical efforts because we will be making early environmental investments using a watershed -based approach. However, we do not anticipate mitigating for impacts beyond those that would be associated with the transportation improvements. Do you need to describe potential alternatives if this scoping meeting will serve as an EIS scoping? (King County DOT) We realize that scoping that is done before an environmental assessment cannot substitute for the normal scoping process that would occur after publication of a Notice of Intent (NOI) to prepare an EIS. Hence, while we do not anticipate holding additional scoping meetings if an EIS is required, any NOI will expressly provide that written comments on the scope of alternatives and impacts will still be considered. Our public notice on this scoping meeting stated clearly that if an EIS were to be prepared "no additional scoping meetings will be held. However, the Notice of Intent, published in the Federal and SEPA Registers, would expressly provide that written comments on the scope of the alternatives, the potential impacts, and the identification of resources would be collected and considered." How is the regulatory permitting process related to what TPEAC is doing? The I-405 team has the option to use the permit streamlining processes developed by the Transportation Permitting Efficiency and Accountability Committees, however, no decision has yet been made to this regard. What level of analysis is being conducted for the Discipline Reports? The discipline reports will be prepared consistent with the methodologies outlined in the WSDOT Environmental Procedures Manual. Project -level analysis will be conducted. Is there a potential for Phasing? We did not look at it during charettes. We are just recently looking at how to stage. For instance we are looking at the direct connectors to 169 and determining whether we need them upon opening or sometime in the future. Will the EA look at something that is less than what we have here? The 9 options evaluated during the charette were within the range of alternatives evaluated in the Corridor Program EIS. We expect to evaluate one alternative the "Proposed Action" all the time making sure that it is consistent with the Selected Alternative in the EIS. What mitigation opportunities are you looking at? (King County DNR) Many areas for mitigation opportunities along the corridor. Coal Creek area east of 405 come up with a proposal. We are looking within the watershed for mitigation looking adjacent to the facility and regionally. We are considering low impact development designs for stormwater facilities. Watershed Characterization for North Renton is due at he end of the month and we hope to have a list of environmental opportunities/mitigation sites. No areas yet but will have some areas identified. Identify opportunities and because they are outside the project area take care of them early and make sure that the agencies give appropriate credit. What typically would be viewed as mitigation would become part of the project. Are you going above and beyond what would typically be required by permits? We want to propose the best mitigation practical and feasible. What is the risk of an EA vs EIS.. The number of Discipline Reports suggest an EIS. We recognize that there are risks. We will be prepared for a change of direction if it comes up. The Discipline Reports will have sufficient data in them so that we will not have to redo any work if it became an EIS. We would however need to analyze alternatives. Jim Leonard of the FHWA explained that if there are "significant" impacts identified the WSDOT would mitigate to a level of insignificance. Is the air quality analysis going to address atmospheric wet and dry deposition. This is something we typically don't see but it can be brought up in the comment period. We will talk to the Air Quality and the Water Quality experts to determine if this needs to be addressed. How does N. Renton fit within the Corridor Program? The North Renton project is part of the larger package of transportation improvements contained in the I-405 corridor master plan. It is one of four sections within the corridor currently undergoing environmental review. The sections were defined to ensure that related transportation improvements are evaluated together at a project level within a geographic section of I-405 that has independent utility, logical termini, and is meaningful to the affected public. The larger I-405 master plan is a multimodal system of improvements cleared through the programmatic I-405 Corridor Program Final EIS and identified as the Selected Alternative in the Record of Decision dated October 2002. The North Renton project is programmed as part of the Phase II 10-year phased implementation of that Selected Alternative. Unlike the three funded I-405 nickel projects in South Renton, Bellevue, and Kirkland, the North Renton project is proposed to be funded primarily through the Regional Transportation Investment District package that is expected to be advanced to voters in the three -county region in November 2004. How do we get the most complete set of program and/or project information? The I-405 FEIS and ROD contain the most complete I-405 Corridor Program information. Why is N. Renton the first I-405 project to go through NEPA? The WSDOT received early funds from the City of Renton to develop footprint engineering for the North Renton project. At this time the N. Renton project has the greatest level of design than any other I-405 project and is ripe for NEPA review. In addition, WSDOT hopes to be in the position to receive funds and get to construction for the N. Renton project in the near future. What is the status of right-of-way acquisition? We have not initiated R/W acquisition for any of the I-405 projects but are currently identifying acquisition needs. We currently know what R/W would be required for the N. Renton project. Who/what groups could be opposed to this project and what are their issues? The Transportation Choices Coalition was actively involved during the I-405 Corridor EIS process. They were mainly concerned with transportation modal balance, potential for induced growth, and air/noise impacts. Another active group is the Kennydale Neighborhood Association, mainly concerned with property acquisition and noise issues associated with the project. What is the public involvement plan and who is coordinating it? Colleen Gants, the I-405 team public information officer, is coordinating the public involvement plan. Will you incorporate local regulations, follow local guidance in writing our discipline reports? The DRs will be written in accordance with the WSDOT Environmental Procedures Manual and should meet the report requirements for local jurisdictions in terms of critical areas. Make sure you review local Critical Areas Ordinances (CAOs) and that your report includes the information necessary to comply with the regulations.

The WSDOT must receive comments for the I405 EA by October 17, 2003. The WSDOT point of contact is: Christina Martinez, I-405 Environmental Lead I-405 Congestion Relief and BRT Projects WSDOT 6431 Corson Avenue S. Seattle, WA 98108-3445 The following comments are similar to ones given to the WSDOT based on the review of the Programmatic EIS for the I-405 Corridor Program. Also included are some more specific concerns related to stormwater issues. STORMWATER: The project should provide water quantity control (detention) and water quality improvements for all existing and proposed right-of-way improvements. The quantity and quality controls should be designed in accordance with the Washington State Department of Ecology Stormwater Management Manual for Western Washington or equivalent standards. If WSDOT storm systems currently discharge or are proposed to discharge to City storm systems, the downstream system capacities should be analyzed and off -site improvements made as part of the project as needed. Water quality and quantity impacts should be mitigated such that there is no impact immediately downstream of the project. Watershed based mitigation will need to show that there are no temporary or long term impacts due to increased peak rate and volume of runoff, along with changed water quality, downstream of the project even if upstream off -site mitigation is proposed by the project. If off -site Watershed mitigation cannot fully mitigate the quantity and quality impacts to the downstream systems (stream or constructed storm systems), then downstream mitigation will also be required. HAFile Sys\SWP - Surface Water Projects\SWP 27-Transporation Projects(TIP)\I-405 Corridor Study\North Renton Project\1004 WSDOT Correspondence\EAScopingComments.doc\RJS\CM\tb f} 51 WETLANDS: At a minimum the project should be held to a "no net loss " of wetland area, function, and value. Replacement ratios for wetland mitigation should at a minimum satisfy Renton's wetland replacement ratios for wetland impacts in Renton. Department of Ecologys or Army Corps of Engineers' replacement ratios should be acceptable if they are equal to or more stringent then Renton's. Wetland mitigation should be done in the same basin and as close as possible to where the impact occurs. WSDOT should establish wetland mitigation banks in the basins where wetlands will be impacted by the project and establish the wetland banks as required by the State's Wetland Mitigation Banking rule. This will ensure that the created wetlands are established, and have the same function and value as the wetland that is to be impacted, prior to the wetland being filled by the project. STREAM BUFFERS/FISH HABITAT: The project should provide mitigation to provide for "no net losses" of stream buffer area, function, and value. In addition, the project's impacts to fish habitat (spawning, rearing, and passage) should be held to the same standard. Replacement ratios (2:1) for impacts to stream buffers and fish habitat should be required. Mitigation should be incorporated at the location of the impact to the maximum degree possible, but the additional mitigation could be done offsite within the same basin or watershed. A mitigation fund could be established for acquisition, restoration, or enhancement of stream buffer and/or prime fish habitat sites that have been determined to be beneficial to improving salmon habitat. The project should not only mitigate for the action impacts but should have a restoration element to offset prior impacts and the fact that mitigation benefits are not immediately achieved, especially when it comes to stream buffers. Any existing culverts or other stream crossing structures that are barriers or restrictions to fish passage should be replaced with new structures that don't prevent or restrict fish passage. Tributary 0283, presently located near the intersection of NE 43rd Street and Jones Ave NE historically was a tributary to May Creek. Through the decades, with the improvements to roads and highways, May Creek and this small tributary have been rerouted and disconnected. Tributary 0283 is a source of potential flooding over NE 43rd Street without annual removal of sediments at the culvert crossing of NE 43rd Street. With the reconstruction of the NE 44"' Street interchange, the potential for reconnecting Tributary 0283 with May Creek exists. One method for doing this is replacing the culverts under I 405 with open channels as proposed for Coal Creek and connecting Tributary 0283 with the ditches along Lake Washington Blvd, which convey water to May Creek. FLOODPLAINS: The project should be required to provide compensatory storage for filling of any floodplain. A "zero rise" to the floodway standard should be applied to the project. The project is also required to comply with all FEMA and Nation Flood Insurance Program (NFIP) standards, since Federal funding will be used. No encroachment into the floodplain should be allowed unless through a hydraulic analysis can demonstrate that the zero rise standard can be achieved. The hydraulic analysis should be based upon future land use condition 100-year flood flows. All bridge crossings of Cedar River and May Creek should be full span of the 100- year floodplain, i.e. no piers, abutments, etc. should be located in the 100- year floodplain. New bridge low chord elevations (bottom of the bridge) should be set above the future land use condition 100-year flood H:\Eile Sys\SWP - Surface Water Projects\SWP 27-Transporation Projects(TIP)\i-405 Corridor Study\North Renton Project\1004 WSDOT Correspondence\EAScopingComments.doc\RJS\CM\tb N elevation by a minimum of 3 feet, or higher on streams or rivers with the potential for large debris flows. Per the Flood Insurance Mapping Study, April 2003 prepared by Northwest Hydraulic Consultants, the pedestrian bridge under I-405 experiences partial or complete pressure flow during the 100- year flood event. It might be possible to remedy this situation by raising or reconstructing the pedestrian bridge coincidentally with the proposed I-405 improvements at the Cedar River crossing. STORMWATER UTILITIES: The I-405 right-of-way creates a major barrier to utility services. Regarding stormwater, a hydrologic and hydraulic analysis of all existing and proposed culverts and storm systems that cross I-405 should be performed to verify that the systems have adequate capacity to convey the 100-year/24-hour storm event for future land use conditions. If the analysis indicates that the system has insufficient capacity, then it should be replaced with a properly sized facility. This is needed to ensure that adequate stormwater conveyance can be provided across the I-405 corridor and that the project will not create upstream drainage problems. Any City -owned structures that have to be relocated or are impacted by the project should be fully coordinated with the City as to sizing and location at no cost to the City. A review of the need for potential new storm system crossings should also be conducted in coordination with the City of Renton Surface Water Utility to address the barrier problem that I-405 presents to the natural drainage and the ability to provide storm drainage service to areas upstream of I-405. The following is a list of 1405 storm crossings from the City's inventory maps, not to be construed as a definitive list (see attached maps): • At SR-169 (Maple Valley Hwy) • South of NE 6°i St • At N 8`1i St • Midway between NE Park Dr and N 81h St • At NE Park Dr (runoff from NE Park Dr) • At NE Park Dr (runoff from NE of I-405/NE Park Dr intersection) • At NE 27`1i Ct • North of NE 44`I' St SHORELINES: The project should comply with the currently adopted Washington State Department of Ecology Shoreline Management Guidelines and City adopted Master Shoreline Program regulations. If you have any questions or need additional information, please contact Ron Straka or Chris Munter.

HAFile Sys\SWP - Surface Water Projects\SWP 27-Transporation Projects(TIP)\I-405 Corridor StudyNorth Renton Project\1004 WSDOTCorrespondence\EAScopingComments.doc\RJS\CKtb WETLANDS: At a minimum the project should be held to a "no net loss " of wetland area, function, and value. Replacement ratios for wetland mitigation should at a minimum satisfy Renton's wetland replacement ratios for wetland impacts in Renton. Department of Ecology's or Army Corps of Engineers' replacement ratios should be acceptable if they are equal to or more stringent then Renton's. Wetland mitigation should be done in the same basin and as close as possible to where the impact occurs. WSDOT should establish wetland mitigation banks in the basins where wetlands will be impacted by the project and establish the wetland banks as required by the State's Wetland Mitigation Banking rule. This will ensure that the created wetlands are established, and have the same function and value as the wetland that is to be impacted, prior to the wetland being filled by the project. STREAM BUFFERS/FISH HABITAT: The project should provide mitigation to provide for "no net losses" of stream buffer area, function, and value. In addition, the project's impacts to fish habitat (spawning, rearing, and passage) should be held to the same standard. Replacement ratios (2:1) for impacts to stream buffers and fish habitat should be required. Mitigation should be incorporated at the location of the impact to the maximum degree possible, but the additional mitigation could be done offsite within the same basin or watershed. A mitigation fund could be established for acquisition, restoration, or enhancement of stream buffer and/or prime fish habitat sites that have been determined to be beneficial to improving salmon habitat. The project should not only mitigate for the action impacts but should have a restoration element to offset prior impacts and the fact that mitigation benefits are not immediately achieved, especially when it comes to stream buffers. Any existing culverts or other stream crossing structures that are barriers or restrictions to fish passage should be replaced with new structures that don't prevent or restrict fish passage. Tributary 0283, presently located near the intersection of NE 43`d Street and Jones Ave NE historically was a tributary to May Creek. Through the decades, with the improvements to roads and highways, May Creek and this small tributary have been rerouted and disconnected. Tributary 0283 is a source of potential flooding over NE 43`d Street without annual removal of sediments at the culvert crossing of NE 43`d Street. With the reconstruction of the NE 44"' Street interchange, the potential for reconnecting Tributary 0283 with May Creek exists. One method for doing this is replacing the culverts under 1-405 with open channels as proposed for Coal Creek and connecting Tributary 0283 with the ditches along Lake Washington Blvd, which convey water to May Creek. FLOODPLAINS: The project should be required to provide compensatory storage for filling of any floodplain. A "zero rise" to the floodway standard should be applied to the project. The project is also required to comply with all FEMA and Nation Flood Insurance Program (NFIP) standards, since Federal funding will be used. No encroachment. into the floodplain should be allowed unless through a hydraulic analysis can demonstrate that the zero rise standard can be achieved. The hydraulic analysis should be based upon future land use condition 100-year flood flows. All bridge crossings of Cedar River and May Creek should be full span of the 100- year floodplain, i.e. no piers, abutments, etc. should be located in the 100- year floodplain. New bridge low chord elevations (bottom of the bridge) should be set above the future land use condition 100-year flood HAFile Sys\SWP - Surface Water Projects\SWP 27-Transporation Projects(TIP)\I-405 Corridor Study\North Renton Project\1004 WSDOT Correspondence\EAScopingComments.doc\RJS\CM\tb elevation by a minimum of 3 feet, or higher on streams or rivers with the potential for large debris flows. Per the Flood Insurance Mapping Study, April 2003 prepared by Northwest Hydraulic Consultants, the pedestrian bridge under I-405 experiences partial or complete pressure flow during the 100- year flood event. It might be possible to remedy this situation by raising or reconstructing the pedestrian bridge coincidentally with the proposed I-405 improvements at the Cedar River crossing. STORMWATER UTILITIES: The I-405 right-of-way creates a major barrier to utility services. Regarding stonnwater, a hydrologic and hydraulic analysis of all existing and proposed culverts and storm systems that cross 1-405 should be performed to verify that the systems have adequate capacity to convey the 100-year/24-hour storm event for future land use conditions. If the analysis indicates that the system has insufficient capacity, then it should be replaced with a properly sized facility. This is needed to ensure that adequate stormwater conveyance can be provided across the 1-405 corridor and that the project will not create upstream drainage problems. Any City -owned structures that have to be relocated or are impacted by the project should be fully coordinated with the City as to sizing and location at no cost to the City. A review of the need for potential new storm system crossings should also be conducted in coordination with the City of Renton Surface Water Utility to address the barrier problem that I-405 presents to the natural drainage and the ability to provide storm drainage service to areas upstream of 1-405. The following is a list of I405 storm crossings from the City's inventory [naps, not to be construed as a definitive list (see attached maps): • At SR-169 (Maple Valley Hwy) • South of NE 6th St • At N 8`' St • Midway between NE Park Dr and N 8°i St • At NE Park Dr (runoff from NE Park Dr) • At NE Park Dr (runoff from NE of I-405/NE Park Dr intersection) • At NE 271h Ct • North of NE 441h St SHORELINES: The project should comply with the currently adopted Washington State Department of Ecology Shoreline Management Guidelines and City adopted Master Shoreline Program regulations.

It is up to you to decide if a representative from your section should attend the meeting. I unfortunately have a conflict and cannot attend the meeting, but Chris Munter will be attending the meeting for me. The way I see it we have three options. The first option is to attend the meeting and provide your input at the meeting. The second option is to write-up our comments and provide them to someone else to present at the meeting or do both as the third option. I will check with Gregg to see who from the City should be attending this meeting and to see how he thinks we as a Department should provide input. This information was provided to me today (9/12/03) from Sandra Meyer who was indicating that all effected City Depts and Section should attend the meeting. The meeting is a scoping meeting for the Environmental assessment that will be needed for the project. So our -comments should focus on environmental issues that would need to be considered and analyzed as part of the project. I noticed on the attachment that if you are going to attend the meeting you have to RSVP by today, probably so they can get an idea of how many lunches to order. I am not sure if they will be having a formal scoping notice and comment period in which written comments can be submitted. It may have already started for all know. At a minimum, I think we should put together a set of written comments that could be submitted to WSDOT at the meeting by whoever is attending the meeting. Please let me know if you plan to attend the meeting and if you will have any written comments Thanks Thanks Ronald J. Straka, P.E. City of Renton Surface Water Utility Engineering Supervisor 1055 S.

Dept. Fish and Wildlife From the Cedar River in Renton to Coal Creek in Bellevue, there are few streams which cross I- 405. During early August 2003, a field examination was done of these streams, both within the I- 405 Right -of Way, and downstream and upstream some distance. Habitat conditions were assessed, impacts of channel alterations made, and suggestions for restoration/mitigation opportunities made. From north to south, fish bearing streams are limited to Coal Creek (WRIA 08.0268) and selected tributaries, May Creek (08.0282) and selected tributaries, and the Cedar River (08.0299) and many of its tributaries. The majority of investigations involved these streams, and not others. Remnants of three other streams were found crossing the R/W. The first is an unnamed independent tributary (08.0281) to Lake Washington adjacent to the SE Lake Wash. Blvd / I-405 interchange (exit 9) the next interchange south of the Coal Creek Parkway interchange. This creek no longer exists downstream of I-405. It ends at the flow control structure for a King County stormwater pond immediately south of the Park and Ride lot. The Park and Ride lot appears to have filled the former stream ravine. A City of Bellevue stormwater system map shows the creek to be piped straight downhill west to Lake Washington, although no clear evidence of this was seen in the field. The lake terminus of this stream may have been in Newcastle Beach Park. There is a remnant open water channel along the southern portion of this park, and wetlands with a flowing channel along the east boundary and entry road of this park. Habitat is very limited in the park; it is unknown whether any fish exist in these channels. Upstream of I-405 and the stormwater pond, the stream is wooded, deeply incised, and draining dense suburban housing. NO r GYPS/ C•-K, / A second remnant stream, `Gypsy Creek ccurs immediately north of May Creek and north of the NE 44`h St. overpass crossing of I-405 (exit 7). The stream is piped to Lake Washington from NE 44`h St., under 405, under the railroad, and under an industrial log sorting yard. The only lnhN- open section of this stream is one immediately downstream of the Denny's, and another very�� short section between 405 and the railroad (WDFW K. Lakey, personal communication). There t,n were once cutthroat trout in this stream remnant; they are assumed to be extinct. There is a narrow wetland riparian zone along the stream segment below Denny's. The last remnant stream is under 405 (approx. MP 5.68) at Sunset Blvd. Sunset Blvd is apparently built on top of where the stream channel was; the stream origin is unknown. It discharges into an open section for only a short distance. It is unknown how, or if, it discharges ultimately to Lake Washington, or to the Cedar River. There is however a 4 foot diameter concrete culvert on the right bank underneath the 405 Cedar River bridge discharging significant flow (at August low flow) onto a riprap pile directly into the Cedar River. Nothing else concerning these remnant streams will be discussed in this report. DRAFT Coal Creek System This system was walked on Aug 5, 2003, from the railroad at 405 upstream to approximately stream mile 4, just downstream of Lakemont Blvd. Coal Creek Within I-405 Right of Way (R/W) exit 10 The stream condition within R/W is pretty dismal. According to the 1975 Stream Catalog, the I- 405 culvert is 475 feet long. It is an approximately 6x6 foot concrete box. The upstream end has a large flow control structure with trash rack attached, and 119`h Ave. SE on top of it. It is assumed that the I-405 eastern R/W boundary is the fence line west of 119'h, and that the 1-405 culvert was extended upstream to accommodate the 119`h construction. The culvert passes under the northbound (NB) off -ramp, under all lanes of I-405, and through part of the final flare of the southbound (SB) on -ramp. The culvert has off -set baffles along its base to aid upstream fish passage. This is a long, long, dark culvert. The stream channel at the outlet has been rebuilt with 3 log/riprap weirs within the last two years. These weirs appear stable and provide a modicum of pool habitat. It is not clear where the 405 R/W ends and the railroad R/W begins. I assume the creek channel has been placed approximately on the boundary line between 405 and a paved, fenced, 2 lane bike path on the shoulder of the SB on -ramp on the east stream bank, and the railroad fill and creek trestle on the west bank. Stream habitat is very poor through this length of open channel. The channel is essentially riprap lined within both 405 and railroad R/W. There is little riparian corridor; the vegetation is sparse deciduous trees and some shrubs and blackberries. There is no floodplain, except perhaps as a high flow flooded left bank wetland south at the culvert outlet. The streambed has cobble, riprap boulders, and some gravel not particularly of optimum size for spawning use. What little gravel there is looks diseased, and is deeply embedded with fine sediments. There is a heavy algal and sediment fuzz on all in -stream rock and gravel, the water stinks on your hands; only a few worms, and no mayflies, caddis, etc. were present. Water had a very odd murky appearance, visibility poor. No fish of any kind were seen — considering the poor quality this was not surprising. I would not let my kids play in this water. Building a new 405 lane in each direction through this Coal Creek Parkway diamond interchange will be a tight squeeze for Coal Creek. Within existing R/W, there is no room upstream to extend the culvert, downstream the creek is in a deep open trench between the road fill and railroad fill. Immediately downstream of the railroad R/W begins the exclusive residential neighborhood of Newport Shores. A major redesign using stabilized earth construction, or vertical walls of some sort might significantly reduce the new footprint, but I doubt will completely eliminate the further encroachment on the stream channel. The likely solution is to construct a new bridge crossing offset north of the existing culvert alignment; the inlet and flood control feature remaining unchanged, the new alignment angling to outlet somewhere near the existing railroad trestle. This will significantly shorten the stream length. There is a lot going on in this interchange — design to minimize stream impact will be a major challenge. Forested Wetland - Immediately south of the Coal Creek 405 culvert outlet, there is a partially forested sliver of land, perhaps 3-5 acres. The sliver is between the 405 road fill slope and the railroad fill slope. There is evidence of standing water in the lowest part of this ground. The Stream Habitat Conditions -- Page 2 -- Kurt Buchanan WDFW V vegetation — cottonwood trees, some alder, and reed canary grass in more open portions, imply a forested wetland. It certainly provides wildlife habitat, but it has no corridor connection to the extensive riparian ravines further east. The City of Bellevue surface water map shows a stream, origin west of I I9th Ave. and east of I I8th Ave. SE, crossing under 405 and feeding into this wetland sliver. The wetland discharges whatever winter flow it may have immediately adjacent to the 405 Coal Creek culvert outfall. This stream appears to provide very limited opportunity for fish use. It may provide some flood storage for upslope origin flows, and possibly allowing very high flows from Coal Creek to back into it, but the connection is not good. Restoration Opportunity — There is little opportunity within the I-405 R/W. Coal Creek Downstream of I-405 R/W The construction of the Montlake Cut and Lake Washington Ship Canal caused the lake surface of Lake Washington to drop approximately 8-10 feet. Prior to this event, it is likely that the old mouth of Coal Creek was somewhere in the vicinity of the railroad trestle/I-405. Extensive coal mining upstream, and wasting of huge amounts of mine tailings into the stream and canyon would have created a larger than normal delta into the lake as that material settled out in the nearshore. The drop in lake level would have exposed the delta, while the deposition continued. Now, the exclusive residential neighborhood of Newport Shores occupies the entire alluvial delta of Coal Creek. The stream channel has been moved, straightened, rocked, and now is totally lined by residential backyards from the railroad to the lake. Part of the delta has been dredged into a Lake Washington version of Venice, with navigation canals for resident's yachts. The stream channel is entirely inadequate to handle flood flows, even though parts of it were enlarged and re -armored in 1987-88. The stream bed is now at the same or higher elevation than the outfalls of the street stormwater drains. Channel deposition of fines still occurs, and it is likely that the mouth at the lake is dredged periodically. The shallow mouth (sheet flow) combined with a record low lake level caused a fish passage barrier during the drought summer/early;.:fall of 1987. Flood control, and flood damage as a result of stormwater is a very important issue for those who live in Newport Shores. There are flood control structures and a sediment control pond at the I-405 culvert, another immediately upstream of Coal Creek Parkway, and a third sediment control pond immediately upstream of this latter structure, all to provide relief to these residents. Managing stormwater from the 405 expansion project will likely be of extreme interest to these homeowners. Restoration Opportunity — None Coal Creek Upstream of I-405 R/W Immediately upstream of the 405 culvert inlet trash rack is an in -stream sediment detention pond, constructed in the late 1980's. It is dredged every couple years, but had not been this year. Water temperature 58 degrees F. A small stream, Newport Creek, enters the Coal Creek sediment pond immediately east of I I9th Ave SE. A very large diameter force main sewer line crosses this stream upstream of a steep series of log weirs designed for fish passage over the sewer line. The stream has a coho and Stream Habitat Conditions -- Page 3 -- Kurt Buchanan WDFW DRAFT cutthroat spawning population. Juvenile passage over these weirs is not likely. Juveniles of both species were seen upstream to the end of survey. Stream temperature was 58 degrees F. The water and gravel quality is much better than in mainstem Coal Creek. The stream channel is in a deep wooded ravine (alder, vine maple, salmonberry) surrounded by private residential housing. Wildlife habitat exists, and is connected to the much larger riparian corridor along Coal Creek. The stream has been moved to the side of the ravine, and a buried sewer main/path parallels the stream. There are water, not sewer, seeps along the toe of slope. The stream has no floodplain, the bed being incised 3-5 feet deeper than original bed level. There is some exposed hardpan in the bed. There is actually large woody debris (LWD) in this channel, the gravel looks decent for an urban stream, is appropriate size for both trout and coho spawning, and there is ample shade from deciduous trees and brush. In an upper stream reach adjacent to a community swimming pool, extreme channel incision has led to construction of a high flow bypass pipe system. The pool had once been the source of highly chlorinated water discharged directly to the stream, leading to fish kills. This problem has apparently been fixed. While the bypass system, and the constructed stream over it are not without problems, the extreme incision, and side slope mass wasting is much diminished. The result of these past events is evident in the channel; there is an excess of gravel, and the % fines is high. Restoration Opportunity — Adding significant amounts of LWD will, over time, trap and sort the gravel, elevate the channel back up onto a floodplain in parts, slow flood flows, and improve fish habitat. This stream will not become a major fish producer. 1191h Ave. SE pond upstream to Coal Creek Parkway - The majority of this long stream reach (approx. 1.2 miles) is now in public parkland. There is one apartment complex, and a series of 6- 8 private right bank residences; all are associated with channel clearing, riprap armor (asphalt and concrete chunks also), and thin to no riparian shade along the right bank. There is a narrow sewer main crossing kept open and un-vegetated. With these exceptions, the riparian condition is very good (60-80% cover). There is very little conifer component, most being cottonwood, alder, big -leaf maple, vine maple, blackberry, and salmon berry. Vegetation adjacent to residences is grass, and blackberry. Bird life is abundant. There are various manmade weirs in this section, all being functional and in reasonable repair, except one associated with a constructed over - wintering mitigation pond. This weir is failing around the left bank; its total demise is imminent. The over -wintering pond is sanded in at the mouth, is perched, water is foul, and provides no useful habitat to anything except mosquitoes. The weir — vegetated soft gabion bank repair adjacent to Coal Creek Parkway (built by WDFW circa 1988) is functional, and the bank now stable and well vegetated. The in -stream structure of this 1.2 mile reach is surprisingly complex for an urban stream. There are LWD complexes, some pools in excess of 2 feet deep, a couple channel braids, and access to floodplain over some limited sections. In other sections, the bed has scoured 3-6 feet below original level. There are pools and riffles in relative abundance for an urban stream. There were two major stormwater outfalls into this stream section, one weighted down by a massive gabion basket structure on the left bank. The one minor right bank stream remnant upstream of an apartment building provides minimal aquatic habitat. In Coal Creek, there is an abundance of gravel, of sizes appropriate for salmonid spawning. I have rarely seen gravel so badly fouled and embedded. The fuzzy scummy look to the gravel noted at 405 was even more pronounced approaching Coal Creek Parkway. Insect life, or even Stream Habitat Conditions -- Page 4 -- Kurt Buchanan WDFW I snails and worms were not found on gravel or cobbles, even in oxygenated riffle areas. The fuzz sediment mix was a total coating of the gravel. When cobble was removed from the streambed, the underlying sediment was black, either coal dust or a reducing anaerobic condition. Water visibility was poor, the water being very milky/murky, but not the "normal" bluish -white milky urban stream look. It had not rained for several days preceding the survey. Very few fish were seen. Coal Creek Parkway to approx. RM 4 downstream of Lakemont Blvd. — Immediately upstream of the King County flood control structure at Coal Creek Parkway, a left bank "tributary" enters Coal Creek. This is the source of the murkiness, and strange chemistry/algal growth noted downstream to the lake. This channel apparently originates from a long abandoned coal mine shaft (K. Paulsen, City of Bellevue, personal communication). Water temperature 58 degrees; mainstem Coal Creek upstream 61 degrees. Flow at 1130 was approximately equal to that coming down the mainstem Coal Creek from upstream. Everything that the water touches in this tributary is covered with a bright orange granular precipitate crust. Rocks, sticks, leaves, muck all orange. There was no gravel in the lower 40 yards of this channel. The bed under the orange was black mud and sand. This orange precipitate continued downstream in the mainstem only a short distance, as a "plume" on the gravel. The discolored water was evident well below I-405. Fish were conspicuously absent visually downstream of this tributary; upstream there were fish in nearly every pool to the end of the survey. The gravel in Coal Creek downstream was coated with the previously described algal/sediment fuzz, and no insect life. Upstream the gravel took on a much more normal appearance, even for an urban stream, and insect life became more evident as I went further upstream. The flow from this tributary originates from within the City of Newcastle jurisdiction. The mine discharge flow apparently fluctuates greatly, and can be more than the main stream. Fish sampling by the City of Bellevue has found far fewer juvenile fish downstream of this tributary than upstream, and fewer, and smaller macroinvertebrates (K. Paulsen, City of Bellevue, personal communication). Clearly something is seriously amiss with this water source. Until source control can render this water more suitable for aquatic life, I would recommend against any expenditure for aquatic habitat enhancement downstream. During the construction of the Coal Creek Parkway flood control structure in 1987/88, Coal Creek was diverted around the construction site, and fish captured and moved. This construction was immediately downstream of the junction with the ugly tributary. There was no evidence at that time of discolored water, or fouled and discolored gravel. Both cutthroat and coho juveniles were abundant and healthy. Whatever has happened to this tributary seems to be relatively recent. Upstream of this ugly tributary, Coal Creek discharges from a large in -stream sediment removal sump/pond. It is large enough to affect water temperature; downstream it was 63 degrees, upstream 61 degrees. From this point upstream to the end of survey, approximately 2 miles, fish (coho and cutthroat) were present in nearly every pool, insect life present but not abundant, gravel in many locations was suitable for spawning, and the ravine entirely wooded and in public park. There is a public path along sections of the main creek. Stream Habitat Conditions -- Page 5 -- Kurt Buchanan WDFW DRAFT The first right bank tributary (08.0273) has had cutthroat and steelhead spawning recorded sporadically over its short reach accessible to fish. This stream originates in back yards, and in confined and eroding a steep and very narrow ravine. It has eroded down to bedrock, which forms the anadromous barrier. There is a persistent sewer gas smell just upstream from this tributary. The bed of Coal Creek has numerous whole bricks and brick chunks downstream of the left bank tributary which drains an old brick making plant. In this section large sculpins were first seen, as well as the first mayfly. Two larger salmonids, age 2+ cutthroat or steelhead, were seen in a deep boulder pool. The stream throughout has a riparian forest, mostly deciduous alder, maple, some cottonwood, and few conifer until the upstream canyon is reached. Sections where the stream has access to a floodplain showed evidence of large gravel movements. Elderberry and salmonberry colonized the gravel deposits. The Stream Catalog notes "an impassible cascade and logjam occurs at RM 2.7, and a 10 foot impassible falls at RM 3.7". These features were not found. There is certainly a canyon section, with large boulders, and exposed bedrock chutes. Upstream of the canyon the channel widens and gradient flattens; gravel is suitable for spawning for all species. The upper section near RM 4 has a long history of unstable banks and bed due to the "cinder mine". Coal mine tailings were dumped into and along the creek, in beds exceeding 30 feet deep for a minimum of 1/3 mile of channel. The debris has slumped, caused landslides and debris flows, and the stream continues to cut down through the deposits. These deposits are still very evident along the banks, and well up the sides of the ravine 100 yards away from the stream. Chunks of coal from this debris are a significant component of the streambed through this section. In 1998 a Jobs for the Environment work crew placed log debris and boulders along sections of badly eroding bank for slow the rate of erosion. So far this repair is working well, but we have not had a major flood test it. Survey stopped at the upstream end of this Jobs for the Environment log work. Temperature at the upstream end of survey 59 degrees, air temperature 68 degrees. Restoration opportunities — leave things be. The upper stream is in a long-term recovery mode. Coal Creek Summary • Aquatic habitat within the I-405 ROW is very poor, and will not be greatly improved by anything we might do. • Fish passage through the 1-405 culvert is about as good as it can get. This culvert should not be extended as part of the widening project. A new crossing should be built. • A major unresolved source of poor quality water was discovered entering Coal Creek just upstream of Coal Creek Parkway. This water profoundly affects aquatic habitat downstream down to and past I-405. • Newport Creek has possibilities, and need, for improvement. I'm not convinced that significant gain can be made due to mitigation needs for I-405 Coal Creek impacts. • There appears to be a significant forested riparian wetland partially within I-405 ROW immediately south of the Coal Creek culvert outfall. • Stormwater impacts are major in these watersheds. Flooding and damage are persistent in the Newport Shores neighborhood. There may be existing flood control structures, and R/D Stream Habitat Conditions -- Page 6 -- Kurt Buchanan WDFW Wi: ponds scattered through the watershed that may be improved in function to accommodate the I-405 additions. May Creek System May Creek (08.0282) was walked on August 11, 2003, from the mouth at Lake Washington upstream to Coal Creek Parkway, approximately stream mile 3. Honeydew Creek (08.0285), the major left bank tributary, was walked from the old Devil's Elbow Road (NE 271h Street) now bicycle path downstream to May Creek, approximately 1/3 mile. It is not recommended to walk, rather crawl, this section of Honeydew Creek ever again. May Creek Within I-405 Right of Way (R/W) Exit 7 Stream conditions within the I-405 R/W are decent, the stream crossing is a bridge hung about 20 feet above the stream. It is possible that this bridge was designed to be widened. It is piling supported, and the ends of the major cross members have rebar showing on the exposed ends. It may be possible to expand the bridge without totally destroying what is there. The stream under the bridge is in much better condition than Coal Creek within R/W. Everything within the R/W is a riprap armored bank, this is the easy way to tell you are within R/W. Armor stops both, upstream and downstream outside the R/W. There is sufficient light penetration to support vegetation everywhere except immediately under the bridge. Both upstream and downstream, cottonwood trees, alder, willows, red -osier dogwood, salmonberry, ferns, and blackberries grow along both banks. Cottonwood trees have colonized the riprap over the last 40 years, and are growing up through it. The channel under the bridge is squeezed too narrow between the riprap banks, which are there to protect the piers from scour. If new piers continue upstream and downstream, they could be drilled shafts, eliminating the need for additional riprap, or repair of that existing. Expanding the width of this crossing will eliminate a number of 30-40 year old riparian trees now growing within the corridor. It is not likely they could be placed directly in the stream under the bridge due to the minimal cross section already there. If the bridge is replaced by a new bridge, then the channel cross section should be expanded immediately under the bridge. The riprap upstream and downstream already colonized by vegetation and trees should be left as is. Immediately downstream of the bridge, two rootwad/log structures have been placed in the channel along the left bank. Someone was worried they would not stay there; they are shackled, chained, and eye -bolted into large anchors. They look very secure. They have created some pool habitat. The water quality was decent, for an urban stream. The gravel was of sufficient size for spawning, and while somewhat embedded in mud and fines, was loose enough for fish to work. It is likely that immediately between the riprap banks under the bridge, any spawning which occurs would be subsequently scoured out during winter storm events. Downstream the channel widens and the riffles should be more stable. Gravel was not fuzzy scummy like at Coal Creek. Few fish were seen in this section, and few insects were present on the gravel. Spawning and rearing of chinook, sockeye, coho salmon, and peamouth chub should be expected, at least sporadically, within the I-405 R/W. It is certainly worth keeping what habitat Stream Habitat Conditions -- Page 7 -- Kurt Buchanan WDFW DRAFT and vegetation there is in decent shape. Without great care during construction, this area will be trashed by the temporary equipment access bridges, staging of materials, and concrete pours/spills into the stream which very often lead to fish kills. The Specials for this bridge work should be very fussy, and close inspection will be required. May Creek Downstream of I-405 R/W From Lake Washington to the I-405 bridge, May Creek is halfway decent as an aquatic and riparian resource. At the lake, the steam has been moved to the side of its historic delta discharge point, and the old sawmill built in its place. The mouth at the lake appears to be dredged regularly. A longtime mill landscape maintenance employee described chinook and sockeye spawning along the mill site, and schools of peamouth chub spawning aggregations. Gravel is of sufficient size for spawning, and although embedded, probably provides successful incubation. There is little wood of any sort in the channel. The mill has been shut for many years, and is undergoing plans for wholesale conversion into some sort of condo residential development. The outside of every channel bend is rock or concrete rubble armored. There is a minimum of riparian vegetation, but the majority of the channel receives shade during at least morning hours. The channel is encroached by lawn and pavement, but active industrial effluent and other disturbance are now absent. Water temperature at the first mill bridge upstream from the lake was 59 degrees at 7AM. Fish were present. Upstream of the mill, there is a railroad trestle crossing and the Lake Washington Blvd bridge crossing. Between these two bridges is a USGS concrete weir stream gauging site. It was in use many years; data was obtained by USGS at least as late as 1988. It provides a very deep scour pool, shaded by surrounding shrubs and trees. Beginning at these bridges and upstream to I-405, the stream is in remarkably good condition considering the channel alterations of the past. This runs for approximately 1/8 mile behind an apparently defunct home manufacturing site. The only activity on this site appears to be storage of very large RV's. The stream has a riparian canopy, however narrow, along most of its length. The "forest" is cottonwood, alder, and maple, being much wider on the left bank (south). LWD is largely absent, but there are a couple natural looking log/stick jams that are creating pools. The channel is very straight, undoubtedly ditched and straightened in the past. The banks are not armored. The stream has access to a floodplain sporadically, primarily on the left bank. There is likely a low berm/dike under the mass of blackberries adjacent to the abandoned home manufacturing site buildings. The gravel is sufficient size for spawning use, and while embedded with mud and fines, is loose. Gravel is not scummy, and looks like it should for an urbanizing stream. Fish are scarce but present. Restoration Opportunity — Certainly the area between the lake and 405 is a very likely candidate for stream and riparian enhancement/restoration. There may be opportunity for wetland creation associated with channel manipulation, particularly behind the abandoned home manufacturing site. LWD could be added into the entire section from 405 to Lake Washington Blvd without causing undue risk to surrounding properties. No structures are immediately adjacent and at risk of flooding. On the Sawmill site, much of the channel is too narrow for the flows, and significant channel enlarging and some lengthening is called for prior to adding wood or doing major riparian planting. Chinook, sockeye, and peamouth chub are known to spawn throughout this section. The abandoned home manufacturing site might be a likely candidate for Stream Habitat Conditions -- Page 8 -- Kurt Buchanan WDFW DRAFT a stormwater treatment site for 405 flows. A very long section of 405 drains to this low spot, both north and south. Perhaps it may be allowed to dump the 405 stormwater directly into Lake Washington without detention, but the treatment of the pollutants will require a considerable piece of ground by itself. May Creek Upstream of I-405 R/W The majority of May Creek upstream from I-405 to Coal Creek Parkway, approximately 2 miles, is forested and in a ravine which narrows going upstream from 405. It is a forested ravine somewhat like the Coal Creek valley. The majority of this area is in King County's May Creek Park. However, the downstream end roughly paralleling Jones Road is in mixed public and private ownership. Going up May Creek, the stream intersects Jones Road no more than 100 yards upstream of 405. There is a flowing Type 4 stream that enters May Creek from a perched culvert, originating in what appears to be a drained and converted, partially filled, wetland. The property is mixed open grass and blackberries, with cottonwood and alder fringing woods. The property is for sale. It may make a wetland creation mitigation site with associated stream. It is too far from 405 to get stormwater for a treatment site. Upstream of this sharp corner at Jones Road, the stream and 405 get closer together. There is a section perhaps 1000 feet long that has clearly been channelized, likely in part due to construction of 405. The stream takes an abrupt angle change away from 405 at the downstream end of this section; the sharp 405-side bank is heavily rock armored. Upstream the channel is 20 feet or less from the R/W fence upslope. 405 is close up a very steep but now forested slope. Building a new northbound lane on the top of this steep partially filled slope will require specialized reinforced earth, or sheet pile, or concrete retaining walls. The existing slope is likely to have been partially side cast, the waste traveling down this long slope. Standard earth fill slopes are not recommended along this reach, probably not even possible. As this straight stretch continues upstream, it becomes squeezed between riprap banks on both sides. The DOT side, and the opposite bank with private residence and old pasture have the same size and kind of riprap. It seems likely that both banks were rocked at the same time, most likely by DOT. There is a private well house and hose on the streambank. The water source may be a seep that comes out of the slope under the 405 slope, or it could just be a shallow sandpoint next to the channel. The stream is very much narrowed through this reach, the bed has riprap chunks and cobble. There is too much scour for much gravel to stay. Caddis were found on some cobble in this very well oxygenated section. At the upstream end of the riprap section, the stream again takes an abrupt angle away from 405 and heads SE upstream. What appears to have happened is that May Creek has been shortened and straightened through the reach. The original stream must have been eroding into the toe of the road slope, or there was fear of scour continuing and undermining the road way up the slope. The stream was moved to just outside the R/W fence, but not further to prevent encroaching on private land (probably productive pasture 40 years ago). Over the intervening years, some deciduous trees, mostly brush, have grown up along this channel. The hill up -slope to 405 is now forested. 1965 era photos should clearly show this channel straightening. Stream Habitat Conditions -- Page 9 -- Kurt Buchanan WDFW DRAFT Restoration Opportunity — There is good reason to look at this channelized reach as a potential mitigation site. All species of anadromous salmonids, including chinook, have access, it adjoins 405, and it was very likely caused by construction of 405. Channel reconfiguration and LWD addition should be possible without undue risk to surrounding properties. Purchase, or conservation easement of the right bank private property would open up the possibilities for this stream reach, and optimize the likelihood of successful work. Very close to the sharp bend where Jones Road turns into NE 3 1 " St., close to a red house, a very 1, ugly stormwater outfall enters the stream on the left bank. The corrugated metal pipe drops 10 feet into the stream, the bank being badly eroded back. At least 50 yards of dirt and bank material have entered the creek over the years. Restoration Opportunity — This outfall needs serious work at its source to minimize flows, and a much more stable and less damaging discharge to the stream. There may be retrofit possibilities on stormwater storage volume at its source. The subdivisions on the hills (Renton) above the valley are older, and undoubtedly built without appropriate stormwater controls. Just after May Creek, and the valley road (now NE 31 st St.) takes the turn east (approximately stream mile 1), the stream is entirely within May Creek Park. The riparian condition is fair; there are many alder, cottonwood, and shrub species along the stream. There is little wood in the channel. It is tempting to look at this perhaps 1/8 mile reach prior to the private homes upstream as an area where LWD could be added. However, the road is close to the stream, the road has little vertical relief above the stream in some places, and local flooding may be a concern for upstream residents. If road closure from flooding is not an issue, then this is another place where LWD placement could be done, on public land, with little risk to adjoining lands. Under -planting the largely deciduous riparian zone with conifers could be pursued regardless of road flood risk. There is a serious problem with the riparian zone being taken over by the exotic highly invasive plant Japanese knotweed. This plant was brought in as an ornamental, and is taking over the riparian world. The source of this plant appears to be the private residences just upstream. Control of this plant is required if any riparian planting project is undertaken. At the end of NE 31s`. St., private homes (3-5) and stream -side yards end at an old homemade steel stringer bridge. There are no other stream side residences, or other major encroachment except for a power line crossing, from this bridge upstream to Coal Creek Parkway (about 1.5 miles). The largely deciduous forest is largely undisturbed and in second growth conditions. There are some scattered conifers, becoming more frequent and close enough to eventually enter the stream upstream of the powerline crossing. Throughout this entire 1 and a half mile stream section, conifer and maple LWD has been placed, not anchored, in the stream this summer. It was placed by helicopter. Placement was concentrated in areas of more open canopy along the stream, for equipment, operator, and ground crew safety. I met a crew contracted to King County that was labeling all the wood pieces/complexes. Through this reach, the channel is much more diverse than downstream. There are steeper sections, some sections incised below the floodplain, some channel braids, and other major parts with full access to the floodplain. The LWD should cause even more interaction with the floodplain. It looks like the choice of this stream reach for LWD additions was a very good idea. A number of small tributaries enter the ravine, each with an alluvial area and access by fish. Only Honey Creek had surface flow into this section of May Stream Habitat Conditions -- Page 10 -- Kurt Buchanan WDFW DRAFT Creek during the survey. There is no conflicting land use or infrastructure that would interfere with the stream doing what streams do. Juvenile coho salmon, and trout were present, but not abundant. Temperature at the first powerline crossing was 63 degrees, air temp 78. Insects on gravel included caddis, but few mayflies, and no stoneflies. The only riprap was at the powerline crossing; it serves no purpose, it's just there. Dirt bikes have heavy use of the powerline R/W and appear to cross the stream, or have access to it. In the mid 1980's, there were persistent rumors of kids on dirt bikes chasing chinook around in May Creek — this may have been an access point. The kids today are probably the children of those bikers. Gravel throughout this reach is sufficient and proper size to support spawning. The gravel is not badly embedded, and is normal color (not covered by petroleum products) and not scummy with dense algae. Upstream approaching Coal Creek Parkway, hardpan becomes exposed in the stream bed, and the bed, and banks begin to exhibit signs of scour. This becomes increasing pronounced at and upstream of the Coal Creek Parkway bridge. Decades of channelization, and draining of wetland storage upstream in the upper May Creek valley, may have led to the scour impacts this far downstream. Channel confinement, residential encroachment, and removal of riparian trees and vegetation upstream of the Coal Creek Parkway bridge are also likely contributors. The gradient flattens upstream of the bridge, but the habitat becomes poorer due to the human impact. All is not well in this long 1.5 mile section. There is an exceptional mud source which enters yf� May Creek immediately downstream (approximately 60 yards) of the mouth of Honeydew Creek. This muddies the stream for perhaps one quarter mile downstream, and has spread a layer of mud over much of the gravel. Its source is unknown. It is likely that it crosses what is left of the west end of Devil's Elbow Road (NE 271h St.), perhaps in a pipe running down the hill. Restoration Opportunity Whatever the source of this large quantity of muck should be investigated, and fixed. Considering the age of the up -slope subdivisions, it may be possible to provide significant stormwater treatment, storage, and a new stable outlet to the stream to compensate for some of the 405 stormwater impacts. May Valley agricultural area, and upper tributaries — There were no areas surveyed on foot. Much of this valley looks as it did in the mid - 1980's, some better, some about the same — poor. There had been a drainage district when this valley was much more intensively farmed. This district was responsible for keeping May Creek ditched, the various lateral drainage ditches cleaned, and the farmed/pastured wetlands drained. This district went defunct, and according to some, the County was supposed to take over the drainage function, but appears not to have done so. Much of the valley is in a state of drainage disrepair, some wetlands are becoming wet again, many pastures and fields are fallow and going back to nature. Other areas are farmed and grazed, and kept beat down. There has been a fencing and re -vegetation effort since the 80's. The riparian area is very narrow where it now exists, and the channel is still straight and with little habitat. This seems a very likely valley to find excellent wetland restoration projects, and natural flood storage possibilities. There may be a significant local opposition to such work. Clearly some are still into the old keep -it -drained agriculture, and would strenuously object to any project, upstream or particularly downstream, which might make their land drain more poorly, or flood more frequently. Drainage and flooding are likely still very important issues to May Valley residents. Close coordination Stream Habitat Conditions -- Page 11 -- Kurt Buchanan WDFW DRAFT with the County watershed steward, and the King Conservation District is absolutely essential to getting good restoration work done in the valley. Some residents have talked about being able to access I-405 mitigation money to get work done, or maybe buy out properties. There may be people interested in the same things you are interested in, and some just the opposite. This may be a time to put money into other organization's efforts, rather than front them directly as DOT. There are at least 3 upper valley tributaries which have coho, cuts, and steelhead spawning and rearing. One roughly parallels, and crosses under, SR 900, the Coalfield Road between Issaquah and Renton. The basin plan may identify beneficial work that may be located within the SR 900 R/W. Honeydew Creek - The creek name is derived from the sewer line that is laid for some distance in the stream bed, or where the creek was before being moved aside. In the early 1980's, high stream flows caused scour and slumps; the sewer main was exposed and ruptured more than once. A section of stream upstream of Devils Elbow Road was rebuilt, and the culvert replaced under the road. The watershed upstream is in dense residential use. Things look much better now than in 1988. The banks and bed are stable, and raw and failing slopes have become healed by vegetation. The stream ravine now has a fairly complete canopy of deciduous trees and shrubs. Cutthroat trout were seen in the reconstructed channel. Stream temperature was 60 degrees. Devils Elbow Road had been a local garbage dumping ground. The original road alignment and stream crossing blew out over 30 years ago. The reconstructed road alignment had slumped east of the culvert crossing and dumped down the stream. The sliver of road left is still cracked and failing. The result of these failures running out into the stream is that old garbage, metal, glass, concrete, and sediment are now common in the stream bed. The slumps and run -outs have re - vegetated to blackberries which cover some of the garbage that hasn't yet gotten to the creek. What isn't blackberries is vine maple. The stream bed gravel is loose, but is moving through in waves with lots of mixed sand. The alluvial area near May Creek appears fairly stable, and should provide some spawning, and rearing habitat for salmonids. Restoration Opportunity - Leave the stream channel alone — it is in a recovery mode. It could be useful to remove the cracked and failing side -cast asphalt road section before it too slumps into the creek. A bike/jogging path would need reconstruction to replace the road sliver. It might be useful to coordinate with the City of Renton concerning retrofit of watershed stormwater facilities. Better control of stormwater would be a long-term benefit to this stream. May Creek Summary • Stream and riparian habitat within the I-405 R/W is decent for an urban creek, except immediately under the bridge where the channel is riprap lined and confined. • Spawning of chinook, sockeye, peamouth chub, and coho salmon should be expected, sporadically, within the R/W. During a dry fall, it may not be possible for chinook and sockeye to even enter the stream or ascend to this location. • Widening the bridge will result in removal of a number of riparian and upslope trees. • Widening I-405 up the hill south of the May Creek bridge will be expensive due to the steep slope that the roadway overhangs. May Creek is at the immediate toe of slope. Specialized retaining wall construction is likely necessary on the fill slope. Stream Habitat Conditions -- Page 12 -- Kurt Buchanan WDFW DRAFT • It is likely that May Creek upstream of the bridge was filled and moved away from the R/W during the 1960's construction of I-405. The channelized stream section is a reasonable, and accessible, candidate for channel restoration. • In -channel, and riparian planting improvements are recommended for the area downstream of I-405 to Lake Washington. • Upper May Creek valley is no longer in intensive agricultural production, and may provide candidate sites for flood storage, and wetland creation / re-creation. Local opposition may preclude this. Lower Cedar River, and Rock Creek, Taylor Creek, and Petersen Creek On August 12, 2003, the lower Cedar River was walked from Lake Washington upstream to River Mile 3, a trestle over the river adjacent to a King County Park. Nearly the entire length was walked on a paved recreational trail. Cedar River Within I-405 Right of Way (R/W) exit 4AB It appears that the entire R/W is covered by the I-405 bridge. Under the I-405 bridge the pedestrian trail crosses the river on a very nice concrete footbridge. Little light penetrates- under either bridge. Some blackberries survive. The channel is riprap lined, and has multiple stormwater outfalls entering the river. One left bank outfall from 405 discharges under the river surface at winter flows, and has scoured a slot in the river bed. On the survey day, there was a right bank 3-4 foot diameter concrete culvert with significant discharge. It had not rained for weeks, so this is a possible piped stream outlet, perhaps from the Sunset interchange. The gravel under the bridge is doubtless used for spawning by both chinook and sockeye. There is much better spawning upstream. Limited rearing is possible in this reach due to poor habitat , conditions. The lights under the bridge are hooded, presumably with the intent to limit the°impact of on -water lighting, and the resultant predation, during salmon smolt out -migration. There is probably little ability to improve the habitat within R/W. The channel capacity appears limited, and the proximity of so many other conflicting structures and uses makes significant improvement unlikely. Providing flood terraces is not possible due to encroachment of road and bridge piers. Stormwater quality control would be a definite improvement. Cedar River Downstream of I-405 R/W The channel is entirely manmade all the way to the lake. The Cedar was diverted out of the Black River/Green River system. The lower Cedar is completely lined with a variety of riprap, concrete, gabion baskets and brick walkway, more riprap, steel pile and timber and concrete panels, etc. Nearer the lake, the Renton Airport forms the entire left bank, and various Boeing plants form the right bank. There is a narrow public park on the right bank, the path being built on a cleverly disguised Corps of Engineers flood control levee. This levee project was just rebuilt in the last few years. Any modification of either bank is unlikely in the near term. Renton Airport occasionally floods; the levee project is probably designed to push the flood waters to the airport side, and away from the Boeing plant side. There is no significant excess channel capacity in the Stream Habitat Conditions -- Page 13 -- Kurt Buchanan WDFW DRAFT lower Cedar. Additions of significant amounts of LWD, now completely missing, should not be expected. Restoration Opportunity — This area is devoted to flood control, and public recreation and footpath. This is not a good place to look for mitigation work, or restoration. Riparian restoration is unlikely, and would be cosmetic only unless there is future re -development of large industrial plant site along the river. If that should occur, then channel restoration may be possible, however remote. Cedar River Upstream of I-405 RIW From the I-405 bridge upstream to RM 3, there is only limited opportunity for improvement. The left bank upstream for about a mile was the site of a large sand and gravel operation, and a brick manufacturing plant. Much of the riverbank has evidence of brick waste, seemingly pushed over the side, perhaps for bank protection. Cottonwood, alder, blackberries and brush have colonized this bank well. The right bank is entirely armored even further upstream. A concrete manufacturer has armored their entire site, and raised it above flood level. The bank has been covered with end -dumped concrete slurry, and now has a veneer of large concrete facing blocks. There has been some preliminary discussion of the City of Renton redeveloping this site for their own use. If this should occur, then removing the concrete completely, and sculpturing the bank back could be possible. Without added river cross section, any addition of wood may cause flooding as a backwater effect. At least the perception that this would happen will preclude any useful amounts of wood to be added in this section of river. Restoration Opportunity — At King County's Riverview Park, there may be some limited possibly for improvement. Two unnamed left bank tributaries enter the river, the furthest d/s is sometimes called Ginger Creek. The upstream creek comes out of a ravine and through a wetland perched and trapped behind the old railroad grade, now bicycle path. The wetland flows under the path, and disappears into a sea of blackberries across the left bank floodplain of the river. This site had been an old farm. It may be possible to clear the blackberries and brush, "unchannelize" the stream, and create wetlands associated with the river floodplain. Riparian revegetation should also be considered, adding to the cottonwood stand now choked with a blackberry, and knotweed understory. This stream was not surveyed to its mouth at the river. Cedar River and tributaries restoration literature - There has been a lot of published work by many groups and governments. I have reviewed the following and found much useful information, and many listings of potential restoration projects: Lower Cedar River Basin and Nonpoint Pollution Action Plan. Adopted by King County Council 1997 Lake Wash ington/Cedar/Sammamish Watershed (WRIA 8) Near -Term Action Agenda for Salmon Habitat Conservation. 2002. WRIA 8 EDT Habitat Assessment Model DRAFT Analytical results for the Cedar River Watershed, 2003. Stream Habitat Conditions -- Page 14 -- Kurt Buchanan WDFW The lower Cedar tributaries, including Maplewood Creek, Molasses Creek, and Madsen Creek, are highly urbanized, and within the Urban Growth Boundary of Renton. Their water quality and habitat was severely damaged 20 years ago, and no remarkable improvement has occurred. Nor is it likely within the time frame of the I-405 project, no matter how much mitigation effort may be applied. There may be opportunities in these urban watersheds to greatly improve various stormwater facilities, gaining water storage and treatment improvements. It does not seem that any tributary in the lower 10 miles of the Cedar may be worth a great deal of effort to improve for habitat purposes, due to the upslope urbanizing impacts anticipated. There are various river floodplain actions perhaps useful to pursue. A number of levee removal — pullback projects are listed, some much further upriver. These projects are very expensive, controversial, affect many homes, and are likely to result in lawsuits as a result of flooding or property damage after the levee work is complete. However, there is an off -channel excavation/enhancement project proposed by the Mid -Sound Fisheries Enhancement Group. It is located immediately east of the Maplewood Golf Course, on the right bank of the river. I have a copy of the preliminary design report, prepared as a class project at the UW Center for Streamside Studies. It looks promising, but I have not evaluated the site. There is no apparent adjoining property or structures that would be at risk from doing work at the site. It seems a better idea to put restoration effort into streams further upstream where water quality is still decent, streams that are outside the Urban Growth areas and so likely to stay rural for the foreseeable future. Three streams in the Maple Valley area are good candidates, lower Rock Creek (08.0338), Taylor Creek (Downs Creek in the Stream Catalog) (08.320), and Peterson Creek (08.0328). These streams have documented chinook spawning and rearing. Watershed characteristics, and restoration actions are well described in the above literature. These streams were partially surveyed on August 13. Lower Rock Creek At the old railroad trestle near the mouth, a wooden flume provided very poor fish passage for many years. It is finally being replaced this summer. The stream was surveyed upstream from the trestle for approximately ''/z mile. The majority of this watershed is in public ownership. Water temperature was 52 degrees. This section of channel looks much as it did in 1987. This is a wonderful stream and riparian resource. The stream is in a fully wooded ravine with abundant LWD of large size. The riparian canopy is mixed deciduous and large second growth conifer. Bed and banks are very stable. A pleasure to walk after the last few streams surveyed. At the Seattle Aqueduct crossing, the culverts are old, and inadequate to pass all flow and debris. The main 4x4 foot concrete box has baffles in the bottom to aid fish passage. Oddities were noted during the survey. There was a surprisingly low density of juvenile salmonids seen considering the high quality rearing habitat available. Viewing conditions were excellent; this is clear non -tannin colored water, so fish would not be missed. Aquatic insects include mayflies and caddis of various species, but they were not distributed on the gravel as expected, only being found in the channel thalweg. Moss was growing well down on most cobble, under the water level during the early morning survey. The moss would normally not be Stream Habitat Conditions -- Page 15 -- Kurt Buchanan WDFW DRAFT so far under water, being scoured off during higher flows, and surviving only on the upper side of cobbles protruding out of the stream. It is apparent that a long time problem is still present. First, a headwater section of Rock Creek has been diverted into the Green River system. This would result in a lower baseflow. The bigger problem is due to the City of Kent wellfield upstream. Their municipal water supply wells are in close hydraulic continuity with Rock Creek. Water levels used to fluctuate widely over the course of a day. Stream flows would be low throughout much of the day when pumping demand was high. This was particularly noticeable during summer and fall months. At night, when pumping demand dropped off, the stream flows would increase again. These widely fluctuating flows appear to be seriously affecting juvenile salmonid rearing, insect production, and the flora of the stream. Restoration Opportunity — Replace the Seattle Aqueduct culverts with a more suitable structure able to pass wood debris. Negotiate a return of the headwater flow to this stream. The City of Kent pumping issues are beyond the scope of potential 405 work. Taylor Creek A windshield, not walking survey, was done. The Taylor Creek watershed is rural, with many small grazing operations. There is a need for fencing and riparian revegetation in many locations. In the upper watershed east of SR 18, there are a number of county road culvert crossings that are partial barriers to fish passage. This upper watershed is a coho, cutthroat, possibly steelhead area. Water temperature 59 degrees, air temp 72 degrees. Culverts to be replaced include 2361h Ave. SE, SE 208th St., and 2581h Ave. SE. It appears the largest problem for fish passage is the SR 18 culvert. It is passable for adults at some flows, but is a barrier to juveniles. Perhaps it will be replaced as part of the SR 18 improvement project. It is an ancient 4x5 foot concrete box with baffles, and is very long. Restoration Opportunity — There is a private, homemade driveway culvert immediately d/s of the SR 18 culvert outlet, at SE 215th St. The culvert is failing, the fill has settled, the road surface is cracked and slumped. The entire structure is in danger of failing during the next flood event. When, not if, it fails, the debris it would dump into the stream would not be beneficial. Downstream along Maxwell Road, the stream has been straightened, has 90 degree corners, and has been maintained by periodic dredging. There are existing flooding problems, the channel has many sections choked with canary grass and cattails, and stock is in the stream in some locations. The stream forms a road -side ditch for approximately % mile. There is some brush and willow riparian cover, in sections of this stream. This is an agricultural ditch, flood channel now partially overgrown and not dredged for awhile. There is a need to significantly improve the stream capacity, and habitat. There are numerous property owners along this ditched stream section, and doing any major improvement will be slow in coming. A number of potential projects are noted for Taylor Creek; it maybe useful to provide money to the county and let them deal with all the property owners. Restoration Opportunity - There have been some past attempts to convert the lush stands of knotweed into better habitat downstream of the last county bridge over Taylor Creek. It might be Stream Habitat Conditions -- Page 16 -- Kurt Buchanan WDFW DRAFT useful to work with such receptive landowners and place LWD in the channel well downstream of the flood -prone ditch, in the area of documented chinook spawning. Peterson Creek The lower 1/3 mile of Peterson Creek was walked, and the area around Peterson Pond. Lower Peterson Creek is in a deep narrow ravine, fully wooded, with numerous logs and jams. There are some old growth logs, one enormous one, spanning the stream. There are more conifer logs and debris in the stream than is growing on the banks or up the slopes. This lower floodplain and canyon is the area most likely used by chinook. Entry from the river is not possible at these low flows. Chinook may not use Peterson Creek during a drought autumn. The upper part of the Peterson Creek watershed is a land of wetlands and lakes/ponds. The stream is tannin color, and water temperatures warm (72 degrees at Pete Pond outlet) due to solar heating in the lakes. Peterson Pond appears to have been made much smaller. There may be opportunity to reverse this. At the outlet there is an ecology block control structure/weir just below the aqueduct pipeline road. Approximately 20 years ago, Peterson Creek downstream had been dredged at least 2-4 feet deeper than the original bed elevation. Spoils piles exist on both banks at least 20 feet back from the stream. This was a big through -cut, made by large., machinery. The cut continued at least 100 yards downstream. Freshwater mussels are growing in this channel; shell samples were taken. There have been very recent additions of LWD into this dredged channel. The alders colonizing the spoils piles are approximately 20 years old. This dredging operation should show clearly on 1980-85 air photos. Peterson Creek just upstream at the lake inlet had been in a long culvert until the early 1980's. Seattle Water Department had kept the stream in a culvert for many years previous. This section between 196`h Ave. SE and Peterson Pond has now grown back to brush. It forms the road -side ditch of Petrovitsky Road. South of Petrovitsky, the Seattle Aqueduct is laid on large concrete pads across an extensive wetland contiguous with Peterson Pond prior to the building of Petrovitsky Road. My guess is that Seattle Water Department dredged the outlet of Peterson Pond, perhaps more than once, to significantly lower the elevation of Peterson Pond. This would give them equipment access, on pads, across the old lake shore of Peterson Pond. Lowering the lake would also prevent the lake level from rising up high enough to float the water main off its foundations. Restoration Opportunity — It may be possible to undo some if not all of the draining of Peterson Pond. If you could put 3-4 feet of water back on Peterson Pond, you would get many acres of added wetland, and many acre-feet of storage. Fish and wildlife/waterfowl habitat would benefit. Raising the lake level may require raising a section of Petrovitsky Road, and the intersection at 196`h Ave. SE. The cross -wetland section of Petrovitsky may be built on cedar puncheon; if so it may still be good. It may require additional weighting of the pipeline to prevent floatation. There may be other, easier wetlands to restore in this watershed. Upstream, the residential lake elevations are probably set by court order and homeowners associations, so added -storage is not likely.

Here are some brief updates - call if you want to know more or have data to share! As always, if there is anyone you think should be added to this list, have them contact me to be added. Also, feel free to pass this message on as you see fit. Much of the GIS development work is coming to an end. We are poised for the analysis phase (which will, of course, also be keeping the GIS analysts busy). We are cleaning up data, finishing the riparian data (see below), and making some last adjustments to the drainage analysis units. We are still on target to have most of the basic GIS work completed by Sep. 15. The stormwater team has completed preparing data for the impact modeling. Over the next few days they are working on the MGS flood modeling They are trying to iron out a few issues such as the soil maps using "urban modified" as a soil type (how do you estimate pre -development land cover based on that?!). Next week they will be estimating pollutant loading. The Department of Ecology team member is investigating what it would entail to add some of the newer stormwater methodologies (such as riparian restoration, wetlands enhancement or restoration, etc.) to the models used by the Ecology Stormwater Manual. The fish habitat conditions report is being edited and should be available in draft form next week. The report on the site -specific wetlands field work was completed and is being edited, it should also be available in a draft form next week. The data development for riparian area analysis has progressed well this week. Staff met with some local government staff to explain our proposed methodology. We will coordinate with other local staff by phone. Photo interpretation was a major focus this week and most areas of the lower Cedar River, lower May Creek, and Lower Coal Creek have been interpreted from stereo pair photos, orthophotos, and GIS data. We still would like to find levee coverages - agricultural levees are difficult to determine from maps and air photos. We still are on target to begin the watershed characterization - synthesis from all the parts now being developed - in mid -September.
