PROJECT BACKGROUND FILE NUMBER: E16-000g SEPA Planned Action APPLICANT: Alan Robertson REQUEST: Approval of a SEPA Planned Action application for construction of a storage yard and wetland enhancement and restoration. LOCATION: 4113 Boeing Access Road (parcel #334840-18go) PROJECT DESCRIPTION: Construction of an outdoor truck and contractor's storage yard, including paving access to the site from Boeing Access Road and paving approximately one acre for the storage area. The project involves restoration of the wetland buffer in response to a code enforcement action from 2014 during which the site was cleared of vegetation and filled with construction debris and other materials. In addition to restoration required as part of the code violation, the applicant is requesting to reduce the buffer of a Category III wetland to increase the paved area of the storage yard, and proposes wetland enhancement and wetland buffer restoration within the remaining area of the buffer and its associated wetland to mitigate for previous impacts from the fill as well as proposed impacts of this project. DETERMINATION: The project falls under the planned action guidelines, and is therefore designated as a planned action. The decision is final with no administrative appeal.

The project includes wetland and wetland buffer enhancement and restoration. Proponent: Alan Robertson for Daniel Assefa (AGED LLC) Location: 4113 Boeing Access Road (parcel #334840-1890) Lead Agency: City of Tukwila, Department of Community Development Other Agencies of Jurisdiction: Washington State Department of Ecology, United States Corps of Engineers, Muckleshoot Indian Tribe Zoning and Comprehensive Plan Designation: Manufacturing Industrial Center/Heavy (MIC/H) Recommendation: The current proposal fits within the scope of a SEPA Planned Action according to the criteria set forth in TMC 21.04.152. The proposal is recommended for approval as a SEPA Planned Action. 1. BACKGROUND/PROPOSAL Tukwila's Manufacturing and Industrial Center (MIC) is one of the Puget Sound region's major industrial centers. Industrial development over most of the sub -area was evaluated in multi -site environmental review. In 1992, a programmatic environmental impact statement (EIS) was prepared for the Duwamish Corridor master plan, a proposal to redevelop Boeing properties in the MIC over a 10-year period. In 1998, sub -area plan/EIS updates extended the previous analysis of the corridor's Boeing properties (about 650 acres) to the entire MIC sub -area (about 1,370 acres). As part of this Planned Action review Tukwila City Hall • 6200 Southcenter Boulevard • Tukwila, WA 98188 • 206-433-1800 • Website: TukwilaWA.gov .01 E16-0009, Tukwila Storage Yard SEPA Planned Action October 13, 2017 Page 2 for the current proposal, the impacts of the current proposal are compared to 1998 Integrated GMA Implementation Plan and Final Environmental Impact Statement to ensure that all impacts have been mitigated. The current proposal is to construct an outdoor truck and contractor's storage yard, including paving the access to the site from Boeing Access Road and approximately one acre for i:he storage area. The project involves restoration of the wetland buffer in response to a code enforcement action from 2014 during which the site was cleared of vegetation and filled with construction debris and other materials. In addition to restoration required as part of the code violation, the applicant is requesting to reduce the buffer of a Category III wetland to increase the paved area of the storage yard, and proposes wetland enhancement and wetland buffer restoration within the remaining area of the buffer to mitigate for previous impacts from the illegal fill as well as the proposed impacts of this project. II. DECISION CRITERIA This proposal was identified as a potential Planned Action because of its location within the subarea subject to the Tukwila Manufacturing/Industrial Center Integrated GMA Implementation Plan and Environmental Impact Statement. The determination of whether a project fits the Planned Action criteria is divided into two phases. Each phase is described below, including a response that explains how the current proposal meets the criteria. 1) In the first phase, a determination is made whether the project satisfies all the following characteristics (contained in TMC 21.04.152 Planned Actions Identified): 1. The action is a "permitted use" located within the MIC/L (TMC 18.36.020) and MIC/H (TMC 18.38.020) zones and/or is an accessory use (TMC 18.36.030 and 18.38.030 respectively). 2. The action is: a. not an "essential public facility" as defined in RCW 36.70.200 and TMC 18.06.270, b. not a conditional or unclassified use, in the respective MIC/L or MIC/H zones, c. not a development, any portion of which includes shoreline modifications waterward of the ordinary high water mark, d. not a development associated with 16th Avenue Bridge construction activities. Response: Use of the site as a truck and contractor's storage yard is a permitted use in the MIC/H zone. The action satisfies all the of items listed in number two above; it is not an essential public facility, it is a permitted use, does not include shoreline modifications, and is not associated with the 16th Ave Bridge construction activities. 2) Once the project has met the initial test to qualify as a planned action, it must then show the following: Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov E16-0009, Tukwila Storage Yard SEPA Planned Action October 13, 2017 Page 3 A. Will all the impacts of the proposal be mitigated by the time the project is complete? Please document all mitigation measures, using attachments if necessary. Response: Based on the answers provided in the Endangered Species Act (ESA) Screening Checklist, the project does not constitute a "take" under ESA. The following provides clarification for items answered "yes" in the ESA Screening Checklist. Compliance with existing codes will mitigate any impacts related to grading, storm water, and hazardous substances. (1) Grading and clearing —The project includes grading and clearing associated with construction of the parking area and wetland buffer restoration. A Temporary Erosion and Sedimentation Control Plan has been prepared for the project. A mitigation plan has been prepared to enhance the existing wetland and to restore the wetland buffer with new plantings. The mitigation area will be subject to maintenance and monitoring to ensure the success of the newly enhanced and restored areas. (2) Processing or handling, storage, or treatment of hazardous substances— The applicant has stated that the site will be used for storage of dump trucks and construction materials including wood and metal scaffolding, forms, and trench holdbacks. No loose or organic material is proposed to be stored. Applicant shall be responsible for obtaining any applicable permits required from other agencies for the proposed paving and mitigation work, as well as any required permits for activities associated with the business on the site. (3) Construction of new impervious surfaces —Construction of new impervious surfaces includes pavement for the new driveway to the site from Boeing Access Road and the storage yard. An oil/water separator and a bioswale are proposed for management at stormwater at the south end of the storage yard, adjacent to the wetland buffer. The project shall comply with the 2016 King County Surface Water Design Manual and is required to obtain a NPDES Construction Stormwater permit. Compliance with stormwater requirements and implementation of BMPs will mitigate impacts of new impervious surfaces to stormwater. B. Is the proposal consistent with the applicable sections of the Tukwila Comprehensive Plan? The proposed project meets the following goals and policies of the Tukwila Comprehensive Plan: Goal 11.1: Support for existing industrial activities in the Manufacturing/Industrial Center and development of new industrial activity, in order to maximize the employment and economic benefits to the people of Tukwila and the region, while minimizing impacts on residential neighborhoods. Policy 11.1.1: Support the efforts of existing industries to expand and new industrial businesses to develop in the Manufacturing/Industrial Center by providing them with Phone: 206-433-1800 • Email: Mayor@TukwilaWA.gov • Website: TukwilaWA.gov E16-0009, Tukwila Storage Yard SEPA Planned Action October 13, 2017 Page 4 economic data, information on available development sites, help in understanding and getting through the permit processes, and other appropriate assistance. Policy 11.1.5: Allow uses that are commonly associated with manufacturing and industry, including those directly supporting such activity, such as offices and laboratories, while prohibiting unrelated uses. III. PUBLIC COMMENTS A Notice of Application was distributed by mail on March 29, 2017 to owners and tenants of properties within 500 feet of the project site, as well as agencies that may have an interest in the project. The Notice of Application was also posted on the project site. Three comments were received in response to the Notice of Application, from the Washington State Department of Ecology, Sound Transit, and the Muckleshoot Indian Tribe. These comments are attached, along with City of Tukwila and applicant's responses to the comments. Several conditions of approval will be added to the Special Permission permit associated with this SEPA application to address comments from the Department of Ecology and the Muckleshoot Indian Tribe. IV. CONCLUSION The current proposal to construct a storage yard and associated wetland restoration and enhancement of a Category III wetland is consistent with the criteria for approval as a Planned Action. The proposed use of the site as a storage yard is a permitted use in the MIC/H zone, and satisfies all other criteria contained in TMC 21.04.152 regarding the proposed use of the site. Proposed actions associated with the proposal are consistent with Tukwila's Comprehensive Plan, and impacts associated with the current proposal will be mitigated.

Sound Transit considered a portion of this site for a multimodal station for Sounder commuter rail and Link light rail. The Sounder commuter rail station did not advance through ST3 planning, and now Sound Transit is considering alternative locations in the vicinity, along E. Marginal Way, for the Link light rail infill station. The proposed development would be in the vicinity of Sound Transit's existing light rail guideway. It would be important that the development of this project not interfere with maintenance access to the light rail guideway during construction or operation of the proposed storage yard.

Attached are the applicant's responses to comments. The City's response to comments is included in blue text below. Please contact me with any questions or additional comments. 1. What are the known dates of the wetland and/or wetland buffer violations on this site? The Dec 2, 2016 letter from Altmann Oliver Associates implies that there were further violations post the City's 10/27/2014 Violation Order? Were there further violations of clearing and grading of this wetland or its buffer? There were no violations of clearing and grading of this wetland or its buffer after the 10/27/2014 Violation Order. See applicant's response for further information. 2. The Violation Order specifically states that the mitigation plan was to be installed by November 30, 2014. Since this work appears to not have been done yet, what is the mitigation for the temporal Toss of wetland functions and wetland buffer functions as a result of the previous clearing and grading actions that have not been mitigated? There is no mention of these mitigation measures in the materials we reviewed. It should be noted that the site may be limited in its ability to fully mitigate for project impacts; therefore, the applicant may need to look at off -site areas, including King County's ILF program. We are planning to issue the Special Permission permit with a condition of approval requiring that the mitigation work shall be started as soon as possible (prior to, and - if needed - independent of, the storage yard construction schedule). 3. Where is the analysis to demonstrate how the requested wetland buffer reduction meets TMC 18.45.080(F)? See applicant's response. The degraded condition of the wetland buffer (including the condition before the 2014 code violation) and the wetland and wetland buffer enhancement proposed are consistent with the criteria in 18.45.080(F) for approval of a wetland buffer reduction. 4. Has the rest of the property been surveyed for wetlands? The 2015 aerial photo from KC IMAP suggests a different vegetation type in the upper NE corner of the property near Sound Transit's rail line. See applicant's response. 5. We didn't see the proposed truck storage plan set sheets with the materials received. Does the applicant have detailed site plan drawings? See attached Preliminary Construction Plans submitted for the Public Works permit (PW16-0132). 6. How does the applicant propose to manage stormwater generated by the new truck storage project? See applicant's response and the attached Preliminary Construction Plans. https://outlook.office365.com/owa/?viewmodel=ReadMessageltem&ItemID=AAMkADcwOTdiODIILTVIMjEtN DQwMi04MjJmLWUSYzBkNjVhZDIOYwBG... 1/4 10/11/2017 Re: Notice of Application - Tukwila Storage Yard PL17-0010 - Jaimie Reavis 7. Has the applicant notified state (WDOE, WDFW) and the Corps of Engineers of their wetland/wetland buffer violation? They may also need state and federal permits to resolve their violations, assuming theses agencies have jurisdiction over the wetland. See applicant's response. Additionally, the following condition of approval will be added to the Special Permission permit, as requested in the comment letter submitted to Tukwila from the Department of Ecology: The applicant shall obtain all necessary state and federal authorizations for wetland and in -water impacts prior to beginning any ground disturbing activities or vegetation removal.

Boeing Access Road Parcel 334840-1890, Tukwila, WA City Files: PL17-0010 Response to SEPA Comments Dear Jaimie: The purpose of this letter is to address the comments received from the WA Department of Ecology and the Muckleshoot Tribe on the subject project during the SEPA Notice of Application period. WA Department of Ecology The comments presented by Paul Anderson with the Department of Ecology related to the impression by DOE that there is a current violation associated with recent wetland filling on the property. I spoke with Paul and explained that the more recent clearing/grading that was the subject of the City violation only occurred within the buffer on top of the historic pre-1990 wetland fill and that no new wetland filling has occurred or is proposed. For reference I have attached the 1988 letter from the Corps of Engineers authorizing the original wetland fill (Attachment A). It was my understanding that Paul seemed satisfied with this clarification. Muckleshoot Tribe Karen Walter with the Muckleshoot Tribe presented the following comments in an April 12, 2017 e-mail to you. My responses to these comments are below Jaimie Reavis May 30, 2017 Page 2 1. What are the known dates of the wetland and/or wetland buffer violations on this site? The Dec 2, 2016 letter from Altmann Oliver Associates implies that there were further violations post the City's 10/27/2014 Violation Order? Were there further violations of clearing and grading of this wetland or its buffer? There have been no violations on this property post 2014. As discussed above, the wetland in the northern portion of the site was historically filled and the filling was subsequently approved by the Corps of Engineers in 1988 (Attachment A). The 2014 violation consisted of clearing and grading on top of a portion of the previously filled area and included a relatively small area of degraded wetland buffer in the southern portion of the proposed development area. 2. The Violation Order specifically states that the mitigation plan was to be installed by November 30, 2014. Since this work appears to not have been done yet, what is the mitigation for the temporal loss of wetland functions and wetland buffer functions as a result of the previous clearing and grading actions that have not been mitigated? There is no mention of these mitigation measures in the materials we reviewed. It should be noted that the site may be limited in its ability to fully mitigate for project impacts; therefore, the applicant may need to look at off -site areas, including King County's ILF program. There has been no temporal loss of wetland functions since no wetlands have been recently filled. Furthermore, the total area of wetland buffer actually impacted on the site by the recent clearing is relatively small and was not functioning at a high level prior to impact. The City of Tukwila's municipal code specifically allows buffer reduction with the implementation of a buffer enhancement plan. We have prepared a buffer enhancement plan (Figures 1 through 8) that will significantly increase the plant species and structural diversity of the degraded buffer on the site Early on in the project an agreement was reached with the City that the buffer restoration would be conducted in conjunction with the proposed project to avoid restoring areas that would then be subsequently impacted as part of a development proposal. The proposed enhancement of the degraded on -site buffer should fully mitigate for the proposed code - allowed buffer reduction and no off -site mitigation is necessary. 3. Where is the analysis to demonstrate how the requested wetland buffer reduction meets TMC 18.45.080(F)? Jaimie Reavis May 30, 2017 Page 3 TMC 18.45.080.F allows for the reduction of a standard by up to 50% only on degraded buffers that do not contain slopes in excess of 15%. The buffer proposed for reduction with enhancement is relatively flat and has been significantly degraded through historic filling and the establishment of invasive plant communities. As part of the enhancement plan, fill material and invasive non-native species would be removed and the area re -planted with a wide variety of native species to increase the plant species and structural diversity of the wetland and buffer over existing conditions. These plantings would increase the wildlife habitat of the area while also providing increased screening to the wetland from the storage yard and would therefore meet the requirements of TMC 18.45.080.F. In addition, a water quality treatment area has been designed for the area adjacent the enhanced buffer. This stormwater facility would treat runoff from the storage yard prior to discharge into the buffer and wetland. 4. Has the rest of the property been surveyed for wetlands? The 2015 aerial photo from KC IMAP suggests a different vegetation type in the upper NE corner of the property near Sound Transit's rail line. Yes the rest of the property was reviewed. The different vegetation type in the NE corner of the property as observed on the 2015 iMAP aerial is a result of the area being used as a Sound Transit staging site and is clearly evident on the 2007 aerial photo (Attachment B). 5. We didn't see the proposed truck storage plan set sheets with the materials received. Does the applicant have detailed site plan drawings? Please request the most recent plan set from the applicant. 6. How does the applicant propose to manage stormwater generated by the new truck storage project? Please see most recent stormwater plans prepared by Barghausen Consulting Engineers. 7. Has the applicant notified state (WDOE, WDFVI/) and the Corps of Engineers of their wetland/wetland buffer violation? They may also need state and federal permits to resolve their violations, assuming theses agencies have jurisdiction over the wetland. As discussed above, I have been in contact with Paul Anderson from the WA Department of Ecology and since there has been no unpermitted wetland fill no further contact with the Corps of Engineers, WDOE, or WDFW is required to resolve the clearing violation.

Sound Transit considered a portion of this site for a multimodal station for Sounder commuter rail and Link light rail. The Sounder commuter rail station did not advance through ST3 planning, and now Sound Transit is considering alternative locations in the vicinity, along E.

Ecology recently received a Notice of Application (NOA) that indicates up to an acre of this site will be paved for a truck storage yard. The subject property is located at 4113 S Boeing Access Road just south of the Boeing Access Road and west of Interstate 5 (Tax Parcel No. 334840-1890). Included with the NOA were an environmental checklist and endangered species checklist. The environment checklist indicates there is a Category A wetland onsite and historic fill will be removed from the wetland as partial mitigation for a reduction in the standard buffer. I understand this parcel is also the subject of a code violation (File CE 14-0439) for unauthorized grading within the wetland and buffer. The wetland on this property is a water of the state subject to the applicable requirements of state law (see RCW 90.48 and WAC 173.201A) and Section 401 of the Clean Water Act (33 USC §1341) and 40 CFR Section 121.2. We will be contacting the applicant about submitting an application to Ecology and the U.S. Army Corps of Engineers (Corps). Ecology does not support the requested reduction in buffer width until after the current code violation has been resolved and the mitigation has been determined to be successful. Any work within the wetland itself will require state, and possibly federal, approval. To ensure resource functions are protected and impacts minimized, we ask that approval of any site work be conditioned with the following: The applicant shall obtain all necessary state and federal authorizations for wetland and in -water impacts prior to beginning any ground disturbing activities or vegetation removal. If you have any questions or would like to discuss Ecology's comments, please call me at (425) 649-7148 or send an email to Paul.S.Anderson@ecy.wa.gov.

Woodway, WA 98020 Re: Secondary Consultant Review for Wetland Delineation - Tukwila Property: (Parcel # 3348401890) City of Tukwila File # CE14-0439). Dear Mr. Assefa: I conducted a site -specific review on your Property to assist with delineating a portion of wetland boundary related to an area that has been graded and filled in recent months. The Property is located at 4113 S. Boeing Access Rd. in the City of Tukwila (Parcel # 3348401890). The area that was reviewed is on the northern half of the Property. Mr. John Altmann of Altmann Oliver Associates (AOA) is the project ecologist and I was asked to provide a secondary consultant review. The City of Tukwila has issued a Violation Notice & Order (# CE14-0439) that includes non -permitted grading and potential wetland impacts. Purpose The purpose of the Secondary Consultant Review is to provide a second professional opinion and assist with determining the wetland boundary specifically within an area that was filled years ago. I conducted a wetland inventory of approximate area on the subject Property for the City after the significant filling events had occurred. Methodology The wetland method used the Corps of Engineers Wetland Delineation Manual (1987), as required, for wetland identification. Currently the Regional Supplement to the Corps of Engineers Wetland Delineation Manual (Regional Supplement -May 2010) is also used specifically for Western Mountains, Valleys, and Coast Region. The wetland determination criteria (vegetation, soils, and hydrology) observed on -site was used to support the investigation findings. Typically "Group A" primary wetland hydrology indicators (surface water, high water table, saturation) listed in the Regional Supplement (2010) are absent during the summer. However, other primary indicators "Group B" - Evidence of Recent Saturation were observed. In addition the soil conditions are significantly disturbed on this site from past filling so obvious changes in topography were used. A map of the Property with approximate locations of wetland flagging is attached ("Tukwila Property" Approximate Wetland Boundary). Due to the amount of old till material the delineation did not install formal wetland data plots and soil pits. Mr. Daniel Assefa, Tukwila Property (Parcel # 3348401890) July 30, 2015 Page 2 Wetland Delineation The northern area of the Property was investigated on July 14, 2015 to review the presence of wetland area and the delineated wetland boundary. The wetland boundary was delineated with 10 plastic flags tied to vegetation. The flagged wetland boundary is shown as approximate on the attached map. This wetland boundary may be surveyed after City verification and approval. The site's topography is nearly flat but there is a gradient that slopes north to south due to past filling events. The recent filling and grading activity did not appear to add a significant amount of fill to the area. Clearing of vegetation is evident but it is a relatively narrow portion of the north Property area. The Vegetation has dominant tree cover black cottonwood (Populus balsamifera) throughout the north area. Shrub cover does change from dense Himalayan blackberry (Rubus discolor) to scattered patches of Douglas' spirea (Spiraea douglasii) in the wetland. Creeping buttercup (Ranunculus repens) and soft rush (Juncus effusus) are groundcover also growing in the identified wetland area. Changes in shrub and groundcover species composition are not abrupt between the wetland and upland but do reflect the presence or absence of seasonal ponded water. The Soil type is not mapped in this area but due to development activities is primarily old fill material. One location near the wetland boundary has visible fill material of about 3 feet in depth. It appears that there may be wetland area formed on top of the fill due to poor drainage and the amount of stormwater runoff that drains to this property. Primary wetland Hydrology indicators were observed on the site to determine the wetland boundary. Due to the time of year the Group A primary indicators (surface water or saturated soils) would not need to be present. However, Group B primary hydrology indicators (evidence of recent inundation) are present. These primary indicators include B 1 — water marks, B2 — sediment deposits, B6 — surface water cracks, B8 — sparsely vegetated concave surface, B9 — water stained leaves, and B 10 — drainage patterns. In summary, this Review assisted with delineating the wetland boundary for City permitting. The visible topographic relief (old fill) and hydrology indicators were relied on for the wetland determination. Please contact me if you require more information or have questions. Sincerely, C.

Our inspection disclosed that the existing fill covers less than 1 acre of wetlands since January, 1997. We also determined that the wetland is hydrolonicelly isolated. Department of the Army regulations dated Nove,nber 13, 1986, authorized certain activities under nationwide permits. Paragraph 330.5(a)(26) of these regulations authorizes discharges of dredged or fill material into nontidal rivers, streams, end their lakes and impoundments, including adjacent wetlands, that are located above the headwaters where the average annual flow is less than 5 c.f.s. Similar' discharges are also allowed into other nontidal waters of the United States that are not pert of a surface tributary syste,4 to interstate waters or navigable waters of the United States. The discharge must not cause the loss or substantial adverse modification of 1 or more acres of wetlands.

Kent, WA 98032 Subject: SEPA application #E16-0009, Boeing Access Road Storage Yard 4113 Boeing Access Road (parcel #334840-1890) Comment Letter #1 Dear Mr. Balmelli, The City of Tukwila has completed review of the SEPA application for the proposed storage yard at 4113 Boeing Access Road (permit number E16-0009). Corrections below are grouped by department or division: Planning Division 1) The SEPA checklist discusses a "Category A" wetland, which is not a type of category the City uses in its wetland regulations. The wetland report submitted under PW16-0132 properly describes the wetland on the project site as a "Category III" wetland. 2) A Special Permission permit is required for review and approval of a wetland buffer reduction. Please prepare and submit application materials to demonstrate conformance with TMC Chapter 18.45, including mitigation sequencing, avoidance and minimization, and a 10-year maintenance and monitoring plan which specifies performance standards for the mitigation area. 3) Restoration of the wetland after illegal fill and grading was done on this site previously is already required as the remedy for the code enforcement violations under CE14-0439. Additional wetland and buffer mitigation/enhancement is required as part of the request to reduce the buffer width. This should be clearly described in the discussion of mitigation activities covered by the SEPA and Special Permission applications. Public Works Department 1) Submit brief narrative that includes what will be stored at the site and what kind of activities will be performed on site. 2) Clarify SEPA application Transportation item 14.f: 20-30 daily vehicle trips. Are these passenger cars or trucks? 3) Submit Traffic Concurrency Test Application to PW. Application fee will be determined by PW staff. 4) Access road slope cannot exceed 15%, however slope of the road was not shown on the drawings, nor the width of the road. Show access road stationing, profile and X-sections. Is a storm drainage system required for the access road?

Sound Transit permit for work under and in near proximity the existing Sound Transit guideway, b. DOE construction permit since more than 1 acre of land will be disturbed during construction. 7) Since Boeing Access Rd has very high traffic volumes, a traffic impact analysis is required addressing among others trip generation and distribution, vehicle turning movements, safety, need for acceleration and deceleration lanes. Your proposal almost creates a 4-legged intersection. Please contact Mr. Robin Tischmak, P.E.,City Engineer, phone 206 431-2455 to discuss scope of the report. 8) Show bioswale rock check dam locations on the plan. 9) Show TESC drainage features, if bioswale is to be used as TESC require cleaning and conversion to final condition. 10) Move pervious asphalt to low end of the yard to infiltrate more runoff before the Swale (unless a good reason can be had, right now they are just infiltrating what falls directly to it). 11) Show downstream pipe resources on BNSF yard (sump pump and freeway crossing); drawing attached 12) July 27, 2016 TIR, Chapter 3.0 Off -Site Analysis states "should runoff ever overtop the wetland it would course over the R/R tracks or through a pipe that the City has no records". A letter from BNSF is required that the R/R Company doesn't object runoff course over the R/R tracks. The Engineer shall obtain record of the subject pipe from BNSF, locate the pipe in the field and show it on the plan.

Police Dept. Parks/Rec Project: Tukwila (Boeing Access Road) Storage Yard Address: 4113 Boeing Access Road (parcel #334840-1890) Date transmitted: September 28, 2016 Response requested by: October 12, 2016 Staff coordinator: Jaimie reavis Date response received: REVIEWERS: Please specify how the attached plans conflict with your ADOPTED development regulations, including citations. Be specific in describing the types of changes you want made to the plans. When referencing codes, please identify the actual requirement and plan change needed. The Planning Division review does not supplant each department's ability to administer its own regulations and permits. However, project consistency at the Planning review stage is important to minimize significant later design changes. More than minimal design changes require further Planning Commission review, even if alteration is required to satisfy a City requirement. This further review is typically a minimum 60-day process. Requirements based on SEPA (e.g., not required by an adopted development regulation) MUST identify the impact being mitigated, the policy basis for requiring mitigation, and the method used to calculate the mitigation required. Calculations of project impacts and the mitigation required (e.g., water capacity, road level of service analyses, or turning analyses) may be required of the applicant. COMMENTS (Attach additional comment sheets and/or support materials as needed.) See PW16-0132 for plan sheets. Other related files include PRE15-0019 and PL16-0039. The application is technically correct; however, a correction Netter will need to be sent once the first round of review is finished to require submittal of a Special Permission permit for working within the wetland/wetland buffer. A wetland enhancement plan was submitted with SEPA plans; let me know if you would like to review a copy. 5' 7ra7&.1I Plan check date: /0//8//6 Comments �� prepared by: Update date: 3.0 OFF -SITE ANALYSIS This project site drains to a wetland area immediately south of the development area proposed for this project site. This wetland area is full of water and at the time of the site survey the whole southern half of the project site was underwater. Therefore, this wetland area is considered a closed depression and should runoff ever overtop the wetland it would course over the railroad tracks or through a pipe that the City has no record of and into the downstream drainage course. Upstream Drainage Analysis Based on the topographic survey prepared for this project, there is a small upstream basin contributing from the north end of the project site adjacent to South Boeing Access Road right-of- way, which tends to course onto the project site, consisting of brushy ground. There is also a Tight rail track overhead on the north end of the project site. ova 6C2—C FAO bi `� Ok, rZ!/Yto# /3n15F re r A 17715.002.doc City of Tukwila Allan Ekberg, Mayor Department of Community Development - Jack Pace, Director NOTICE OF COMPLETE APPLICATION September27, 2016 Mr. Dan Balmelli Barghausen Consulting Engineers 18215 72nd Ave S Kent, WA 98032 Subject: 4113 Boeing Access Road (parcel #334840-1890) - SEPA Planned Action Application E16-0009 Dear Mr. Balmelli: Your application for a SEPA Planned Action for construction of an asphalt pavement area for use as a storage yard on the south side of the Boeing Access Road (parcel #334840-1890) was considered complete on September 14, 2016 for the purposes of meeting state -mandated time requirements.
