BACKGROUND/PROPOSAL The metal corrugated storm drainage pipe to be repaired/replaced ranges from 24" to 36". In the winter of 2012/2013, the system experienced multiple failures during large storm events. Investigation of the system has determined that the pipe is in very poor condition and that additional failures are likely. Riverton Creek enters the storm drain system through a pipe inlet at the upstream extent of the project and contributes year round flow through the system. Additional flow is contributed from a 24" trunkline that drains East Marginal Way south of project limits. The project will replace the Riverton Creek pipe inlet with an adequately sized inlet structure with overflow capabilities and a trash rack to prevent clogging of the system. The existing system routinely experiences blockages, causing upstream flooding, creating unsafe conditions for City crews and disturbance of aquatic habitat to remove the blockages. The total length of pipe replacement is approximately 1,470 linear feet and is divided into two reaches which extend upstream and downstream from a competent section of storm drain across S. 124th Street. Starting at the Riverton Creek inlet (just south of S. 126th Street), the upstream reach of the project will replace approximately 680 linear feet of 30" corrugated metal pipe with new 42" storm drain pipe and concrete storm drain structures, extending to S. 124th Street. The new pipe will be installed offset from the existing alignment where possible to allow the existing pipe to serve as a gravity bypass during installation and to minimize utility conflicts. Downstream of S. 124th St. the project will continue pipe replacement north along East Marginal Way South. The portion of the project north of S. 124th St. will replace approximately 790 linear feet of corrugated metal pipe with sizes ranging from24" to 36" with 42" drain pipe and concrete storm drain structures. This section will follow a new alignment along the centerline of the street in order to avoid conflict with utilities and existing buildings. The project terminates at the location where 42" concrete pipe installed in conjunction with more recent development begins. The newer 42" pipe extends another 9470 linear feet to SR 99 right-of-way before ultimately discharging into the Duwamish River. Approximately 1500 square feet of grasses and Himalayan blackberry will be removed for replacement of the inlet structure at the upstream end of the project. Ground disturbance and clearing will be mitigated by planting native plant species over all disturbed areas. V.

The series of e- mails exchanged between the City and Tribe are attached. The questions from the Tribe are listed below, followed by the City's response: 1. How much flow from Riverton Creek goes into the 1470 linear foot pipeline that will be replaced? Answer: A total of 211 acres out of 394 acres drain to this section of pipe. This represents a total of approximately 54% of the basin. I estimate the summer base flows at about 1-2 cfs. The pipe was designed for a minimum gravity capacity of 72 CFS. This matches the capacity of the downstream piped section not being replaced. The existing system being replaced is a 36" system with approximately a 45 CFS capacity when new. It is important to note that the portion of the basin draining to this reach is almost entirely developed (> 98%). 2. The project description notes that a trash rack will be placed on the pipe inlet and likely maintained. How does the City propose to mitigate for the blockage of wood and sediment that would otherwise be available to downstream areas of Riverton Creek and potentially the Green River? CL Page4of7 H:\E14-006 EMWS Storm Drainage Repair\SEPA Staff Rpt. 05/13/2014 5:32 PM E13-015: SEPA Staff Report East Marginal Way South Storm Drainage Repair Project May 13, 2014 Answer: The trash rack spacing was increased to 6" to allow sediment, gravel, and rocks up to 6" to pass. Given the size of the materials I have observed within the creek, I would not expect to trap any rocks since the larger ones do not tend to move and they have not been observed within this reach. Plant material will get trapped on the trash rack. Leaves usually will pass downstream unless trapped by branches. The maintenance crews typically will rake the debris off the rack two to three times a year. They will use a rake to pull the material to the top of the bank where it usually is just left within the stream environment to decompose. Large branches are placed on the side of the stream and then the small branches and leaves flow downstream. I am not aware of any time that they have had to haul material off of the site when cleaning the current trash rack. 3. Does the City have a policy for daylighting streams or stream segments where streams are currently in pipes and if so, how does this policy apply to this project? Answer: Yes, the newly updated Natural Environment Element of the Comprehensive Plan (approved last year) includes two relevant policies which read as follows: "Policy 4.5.5: Prohibit piping of watercourses except where unavoidable for access purposes. Where feasible and practical to create healthy riparian habitat, encourage removal of piped sections of watercourses as part of new or redevelopment and public projects. "Policy 4.5.6: Prohibit creation of new fish barriers and, where possible, eliminate existing barriers to fish passage through implementation of capital improvement projects and by providing incentives to private sector development." The stream unfortunately is piped under parking lots, in the ROW or too close to buildings to allow any kind of daylighting that would improve habitat for the fish. I think the existing piped system is an unfortunate legacy from the days when streams were not viewed as an important part of the ecosystem but rather something to be moved around out of the way of development. 4. If there is no opportunity to daylight the stream or separate the stream from stormwater infrastructure, what is the City's proposed mitigation for keeping 1470 linear feet of Riverton Creek in the replaced pipeline? Answer: The City has the Riverton Creek Flap gate removal project on the books and would like to see it completed. The City could commit to completing this within a five year window as mitigation for this project. CL Page 5 of 7 H:\E14-006 EMWS Storm Drainage Repair\SEPA Staff Rpt. 05/13/2014 5:32 PM E13-015: SEPA Staff Report East Marginal Way South Storm Drainage Repair Project May13, 2014 After reviewing the City's responses above, the Tribe followed up with two additional questions as follows: 5. Is the Riverton flapgate already scheduled to be removed and if so, when? Answer: The Riverton Creek Flap Gate Removal project is currently scheduled to have the design completed in 2016 and construction in 2017. We will need to secure additional construction money but in past discussions with WRIA 9, it appears the project will score well with granting agencies. 6. If Riverton flapgate removal is proposed as a mitigation measure, how does the City propose to commit to its removal within 5 years? Answer: The project is in the approved 2014 Capital Improvement Plan adopted by the City Council. Dates often slip due to permits or funding issues. I can add a note to the project description that states the City has committed to the Muckleshoot Tribe that the project will be completed by 2019 as mitigation for the East Marginal Way Pipe Replacement Project. This statement will also be added to the Council Approval process that awards the Pipe Replacement Project so they are aware of this commitment. The Tribe provided the following final comments on the project after reviewing all of the City's responses: "At this point, we agree with the City's proposed mitigation for this project. We do want to note a couple of things: • "The City should pursue daylighting the stream and separate from the stormwater conveyance if and when the areas within the replaced pipeline project re -develop or otherwise are modified. • "If the replaced pipeline sections are not fully fish -passable, the City may be required to make them fish passable or otherwise create fish passage conditions sooner than when the pipelines would be due for replacement." The City acknowledges receipt of these two additional comments. VII. CONCLUSION The proposal does not have the potential to impact the environment with the proposed mitigation measure identified below. VIII. STAFF RECOMMENDATION Staff recommends that pursuant to WAC 1997-11-340 (3), a Determination of Nonsignificance with mitigation (MDNS) be issued for this project. The following mitigation measures must be met: CL Page 6 of 7 H:\E14-006 EMWS Storni Drainage Repair\SEPA Staff Rpt. 05/13/2014 5:32 PM E13-015: SEPA Staff Report East Marginal Way South Storm Drainage Repair Project May13, 2014 1. Add a note to the Capital Improvement Plan project description of the Riverton Creek flap gate removal project that a commitment has been made to the Muckleshoot Indian Tribe that the project will be completed by 2019 as mitigation for the East Marginal Way Pipe Replacement Project and provide this information to the City Council as part Council approvals needed for the Pipe replacement process to ensure their awareness of the importance of the flap gate's removal. This MDNS is based on impacts identified within the environmental checklist, attachments, and the above "Final Staff Evaluation for Application No. E14-0006", and is supported by plans, policies, and regulations formally adopted by the City of Tukwila for the exercise of substantive authority under SEPA to approve, condition, or deny proposed actions.

Sorry but this is the first I had a chance to see these responses as I was tied up in a meeting all afternoon. Based on the City's responses, we have a couple of follow- ups: 1. Is the Riverton flapgate already scheduled to be removed and if so, when? 2. If Riverton flapgate removal is proposed as a mitigation measure, how does the City propose to commit to its removal within 5 years?

Based on the information we have reviewed, we have some questions as noted below: 1. How much flow from Riverton Creek goes into the 1470 linear foot pipeline that will be replaced? Answer: total of 211 acres out of 394 acres drain to this section of pipe. This represents a total of approximately 54% of the basin. I estimate the summer base flows at about 1-2 cfs. The pipe was designed for a minimum gravity capacity of 72 CFS. This matches the capacity of the downstream piped section not being replaced. The existing system being replaced is a 36" system with approximately a 45 CFS capacity when new. It is important to note that the portion of the basin draining to this reach is almost entirely developed (> 98%). 2. The project description notes that a trash rack will be placed on the pipe inlet and likely maintained. How does the City propose to mitigate for the blockage of wood and sediment that would otherwise be available to downstream areas of Riverton Creek and potentially the Green River? 2 Carol Lumb From: Ryan Larson Sent: Tuesday, May 13, 2014 8:25 AM To: 'Karen Walter'; Carol Lumb Subject: RE: East Marginal Way S storm pipe replacement, E14-0006, Notice of Application Karen, is the Riverton flapgate already scheduled to be removed and if so, when? The Riverton Creek Flap Gate Removal project is currently scheduled to have the design completed in 2016 and construction in 2017. We will need to secure additional construction money but in past discussions with WRIA 9, it appears the project will score well with granting agencies. If Riverton flapgate removal is proposed as a mitigation measure, how does the City propose to commit to its removal within 5 years? The project is in the approved 2014 Capital Improvement Plan adopted by the City Council,. Dates often slip due to permits or funding issues. I can add a note to the project description that states the City has committed to the Muckleshoot Tribe that the project will be completed by 2019 as mitigation for the East Marginal Way Pipe Replacement Project. This statement will also be added to the Council Approval process that awards the Pipe Replacement Project so they are aware of this commitment. - Ryan From: Karen Walter[mailto:KWalter@muckleshoot.nsn.us] Sent: Monday, May 12, 2014 5:24 PM To: Carol Lumb Cc: Ryan Larson Subject: RE: East Marginal Way S storm pipe replacement, E14-0006, Noticeof" Application Carol, Thank you for getting responses back to our questions forrt'his project.

The project description notes that a trash rack will be placed on the pipe inlet and likely maintained. How does the City propose to mitigate for the blockage of wod and sediment that would otherwise be available to downstream areas of Riverton Creek and potentially Green River? Answer: The trash rack spacing was increased to 6" to allow se 'ment, gravel, and rocks up to 6" to pass. Given the size of the materials I have observed within the creek, I would not exp ct to trap any rocks since the larger ones do not tend to move and they have not been observed within this reach. Plant material will get trapped on the trash rack. Leaves usually will pa downstream unless trapped by branches. The maintenance crews typically will rake the debris off the rack two to three 'mes a year. They will use a rake to pull the material to the top of the bank where it usually is just left within the stream nvironment to decompose. Large branches are placed on the side of the stream and then the small branches an leaves flow downstream. I am not aware of any time that they have had to haul material off of the site when cleaning th current trash rack. 3. Does the City have a policy for daylighting streams or stream segments wherstreams are currently in pipes and if so, how does this policy apply to this project?

I am not aware of any time that they have had to haul material off of the site when cleaning the current trash rack. 3. Does the City have a policy for daylighting streams or stream segments where streams are currently in pipes and if so, how does this policy apply to this project? Answer: Yes, the newly updated Natural Environment Element of the Comprehensive Plan (approved last year) includes two relevant policies which read as follows: "Policy 4.5.5: Prohibit piping of watercourses except where unavoidable for access purposes. Where feasible and practical to create healthy riparian habitat, encourage removal of piped sections of watercourses as part of new or redevelopment and public projects. "Policy 4.5.6: Prohibit creation of new fish barriers and, where possible, eliminate existing barriers to fish passge through implementation of capital improvement projects and by providing incentives to private sector development." The stream unfortunately is piped under parking lots, in the ROW or too close to buildings to allow any kind of daylighting that would improve habitat for the fish. I think the exisiting piped system is an unfortunate legacy from the days when streams were not viewed as an important part of the ecosystem but rather something to be moved around out of the way of development. In this particular reach of the stream system, Given the location of the stream in this location there is no room to remove the stream from the pipe — the location of buildings in some portions of the pipe preclude daylighting the stream 4. If there is no opportunity to daylight the stream or separate the stream from stormwater infrastructure, what is the City's proposed mitigation for keeping 1470 linear feet of Riverton Creek in the replaced pipeline? Answer: The City has the Riverton Creek Flap gate removal project on the books and would like to see it completed. The City could commit to completing this within a five year window as mitigation for this project. We appreciate the opportunity to review this project and look forward to the City's responses. We may have comments subsequently.

The comment period must unfortunately be extended to allow for the 14 day comment period, which takes the comment deadline to COB on Monday, May 12th I have a call in to Karen Walter at the Tribe to see if she will have any comments/concerns about the project and will let you know as soon as I have spoken with her. It is hard to anticipate what mitigation, if any, the Tribe might request. One mitigation measure the Tribe might request would be to daylight the stream where there are opportunities. Since much of the pipe will be moved to City right-of-way this would not provide an opportunity to daylight the stream — in other areas the pipe runs where no habitat benefits could be expected if the stream were day lighted given the close proximity of buildings and lack of room for a reasonably sized buffer,. Native plantings are another mitigation measure the Tribe frequently requests — I think the only spot where that is a possibility is at the inlet for Riverton Creek as the rest of the pipe is underground. And discharge to the Duwamish is covered by the City's NPDES permit I am assuming. At this point, those are the possible mitigation measures I can think of that the Tribe might request, but I will provide feedback after talking with Karen. You have my profuse apologies. Let me know if you have any questions. carol Carol Lumb, Senior Planner Department of Community Development City of Tukwila 6300 Southcenter Blvd, Suite 100 Tukwila, WA 98188 206-431-3661 CaralLumb2Tuk wily kVa.h ov Tukwila, the City of opportunity, the community of choice. 1 eit g of J uliwiea Department Of Community Development AFFIDAVIT OF DISTRIBUTION I, Teri Svedahl , HEREBY DECLARE THAT: Mailing requested by: Teri Svedahl x Notice of Application Notice of Decision Notice of Public Hearing Notice of Public Meeting Determination of Non- Significance Mitigated Determination of Non - Significance Determination of Significance & Scoping Notice Short Subdivision Agenda Notice of Application for Shoreline Mgmt Permit Shoreline Mgmt Permit Board of Appeals Agenda Packet Board of Adjustment Agenda Packet Official Notice Notice of Action Other: Was mailed to each of the addresses listed/attached on this _14th day of _April , _2014_ Project Name: EMWS Emergency Storm Drain Repair Project Number: PL14-0014 Associated File Number (s): E14-0006 Mailing requested by: Teri Svedahl Mailer's signature: 7) /k2/74( -f' �� — G W:\ADMIN\ADMIN FORMS\AFFIDAVIT OF DISTRIBUTION.DOC M00M11 City of Tukwila Notice of Application SEPA Application E14-0006 Location: East Marginal Way South btw S. 120th Pl. and S. 126th St. Applicant: City of Tukwila, Public Works File# E14-0006 4 Proiect Planner: Carol Lumb, 206-431.3661 or Car- ol.Lumb @tukwilawa.gov Project Description: Replace approximately 1,470 linear feet of failing storm drainage pipe along East Marginal Way S.

Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. The East Marginal Way S Storm Pipe Replacement project provides necessary replacement of the failing storm drainage system along East Marginal Way. In the winter of 2012/2013, the system experienced multiple failures during large storm events. Subsequent investigations of pipe condition indicate that the majority of the system, which is comprised of 24" to 36"corrugated metal pipe, is in very poor condition and additional failures will become increasingly likely without replacement. Riverton Creek enters the storm drain system through a pipe inlet at the upstream extent of the project and contributes year around flow through the system. Additional flow is contributed from a 24" trunkline that drains East Marginal Way south of the projcet limits. This project will replace the Riverton Creek pipe inlet with an adequately sized inlet structure with overflow capabilities and a trash rack to prevent clogging of the system. The existing system routinely experiences blockages, causing upstream flooding, creating unsafe maintenance conditions for City crews and an unneccessary disturbance of aquatic habitat to remove blockages. The total length of pipe replacement is approximately 1,470 linear feet and is divided into two reaches which extend upstream and downstream from a competent section of storm drain across S 124th Street. Starting from the Riverton Creek inlet, the upstream reach of this project will replace approximately 680 linear feet of 30" corrugated metal pipe extending to S 124th St with new 42" storm drain pipe and concrete storm drain structures. The new pipe will be installed offset from the existing alignment where possible to allow the existing pipe to serve as a gravity bypass during installation and to minimize utility conflicts. Where it crosses S 124th St, the existing storm drain system is constructed with 42" concrete pipe in good condition. As a result, this portion of the system will not be replaced. Downstream of S 124th St, the project will continue pipe replacement north along East Marginal Way. The portion of the project north of S 124th St will replace approximately 790 linear feet of corrugated metal pipe with sizes ranging from 24" to 36"with 42" storm drain pipe and concrete storm drain structures. This section will ollow a new ali!nment alon! the centerline o the street in order to avoid con ict with utilities and buildings. The project terminates at the location where 42" concrete pipe installed in conjucntion with more recent development begins. The newer 42" pipe extends another 940 linear feet to the State Route 99 Right of Way before ultimately discharging into the Duwamish River.

Use separate sheets as necessary. Applicant Responses: Agency Comments d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. No e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. This project requires excavation and backfill to replace the failing storm drainage pipe and install new storm drain pipe and catch basins; however, there will be no change in final grades compared to the existing conditions. Excavated material that is not suitable for backfill will be replaced with clean fill from a WSDOT approved pit source. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. g. Erosion could result during construction of the upstream inlet near the stream. All other construction has limited opportunity for erosion due to extremely flat gradient. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)?
