Dear Mr . Pywell : This letter is a follow up of my June 14, 1997 letter commenting on, this project . After further review of the site and old aerial photographs, I have determined that this is not a natural watercourse but a constructed stormwater ditch, and would not provide habitat due to irregular flows and poor water quality. Therefore a Hydraulic Project Approval will not be required . However, the ditch is providing some water quality benefits and I would recommend that a minimum of 100 feet of the ditch be constructed as a bioswale to filter the water prior to its discharge into Springbrook Creek . Any project developed on this site will still have to meet Department of Ecology Stormwater Manual for 'Puget Sound for the discharge of stormwater to. Springbrook Creek . If you have any questions please call me a ( 425) 391-4365 . I would like to thank you for your cooperation in our effort to protect and perpetuate our state ' s fish ,and wildlife resources .

June 10 Applicant and applicant's representatives first made aware of WDFW letter at Fill and Grade Permit hearing. Hearing Examiner left the record open on this decision until June 24, 1997, pending additional communications with WDFW. June 10 Telephone message left for Phil Schneider, WDFW Fisheries Habitat Biologist,by Vicki Morris,Environmental Consultant, applicant's representative. Requested the opportunity to discuss his letter. June 11 Bill Taylor, Taylor Associates,Fisheries Biologist and Aquatic Scientist, contacted by Vicki Morris to discuss WDFW letter of comment and additional information needed. June 12 Pierre Grady Way Fill and Grade project information provided to Bill Taylor. June 12 Phil Schneider returned call to Vicki Morris. Discussed his observations of potential for fish access to the Pierre Grady Way site ditch: potential winter time side channel rearing habitat. Discussed possible sources for the additional information he is seeking. Identified Comprehensive Fisheries Assessment of the Mill Creep Garrison Creek and Springbrook System prepared by Harza for the City of Kent(1995). June 12 Telephone message left for Bill Walinski, City of Kent Public Works Department, by Vicki Morris, requesting a copy of the Mill Creek Fisheries Assessment. June 12 Bill Taylor retained to conduct additional information gathering requested by Phil Schneider. June 12 Bill Taylor talked with Phil Schneider. Discussed appearance of hydraulic function of the system, types of information to be gathered for confirmation of hydraulic function, and possible alternatives to culverting and filling the ditch that may be required by HPA. 7732 18TH AVENUE NORTHEAST - SEATTLE, WA 98115-4426 - FAX: (206) 523-4648 • PHONE: (206) 522-8057 6-24-1997 7:49AM FROM V MORRIS CONSULTING 206 523 4648 P. 2 • Mark Pywell/Vicki Morris Re: Pierre Grady Way Site, LUA 97-046, SP June 24, 1997 June 13 Vicki Morris contacted Phil Schneider to request a meeting with applicant's representatives. June 14 Site visit by Vicki Morris and Bill Taylor to inspect the system: onsite ditch muddy, no standing water except near outlet culvert; discontinuous connection to Oakesdale Avenue SW culvert (two separate culverts with depression in between, ±1 ft drop between ditch bottom and ditch outlet culvert); and indistinct side channel between Springbrook Creek main channel and Oakesdale Avenue SW culvert. Noted opportunities for fly stranding if system flow was discontinuous during fish presence in these areas. June 16 Meeting in Eastgate: Phil Schneider,Don Moody,Bill Taylor, Vicki Morris to discuss issues, concerns and observations; and data to be collected. Discussed. potential absence of WDFW jurisdiction/interest if the ditch is a totally artificial system that only flows during storm events. June 17 Significant rain storm mid-day. Taylor Associates field crew at site to take flow measurements. Anecdotal observations: Don Moody at the site 3:30 PM when the rain stopped. Water was flowing 18 inches to 2 ft deep in the ditch at that time. Returned to the site at 4:30 PM; flow was approximately the same. Returned to the site the next day, 6/18/97, at approximately 11:00 AM—the ditch was not flowing at all. June 17-23 Taylor Associates field work: collecting water stage(water surface elevation) versus discharge information to provide an estimate of Springbrook Creek flow at the point when it would enter the Oakesdale Avenue SW culvert and create a hydraulic connection with the Pierre Grady Way site system. Looking for Springbrook Creek monthly flow duration curves to estimate the amount of time the creek is high enough to provide easy access to the site culvert and ditch. Data collected todate: 3 flow measurements(including one very high flow following 6/17/97 storm); and cross-sectional profile of Springbrook Creek channel to invert of Oakesdale Avenue SE culvert, and to invert of Pierre Grady Way site ditch culvert. June 18 • Richard Chase, City of Kent Public Works Department, returned call to Vicki Morris. Offered to loan a copy of the Mill Creek Fisheries Assessment. June 19 Vicki Morris picked up the Mill Creek Fisheries Assessment from the City of Kent. Also stopped at Walker& Associates(Tukwila)to review historical aerial photograph record (1936-1995). Historical photos show ditch parallel to railroad embankment for the entire period of record; i.e., it appears to have been excavated at the time of railroad construction. Vicki Morris provided a copy of the Mill Creek Fisheries Assessment and historic aerial photos to Bill Taylor. An appendix to the Mill Creek Fisheries Assessment contains only a limited amount of USGS stream gauge data. 2 6-24-1997 7:50AM FROM V MORRIS CONSULTING 206 523 4648 P. 3 I Mark PywelWicki Morris Re: Pierre Grady Way Site, LUA 97-046, SP June 24, 1997 June 19 Telephone calls to Bill Taylor,Phil Schneider and Don Moody by Vicki Morris to advise of findings in historical aerial photo review: ditch appears to have been artificially created. . June 20 Telephone calls to Bill Taylor and Phil Schneider by Vicki Morris to request status reports for letter to be written to the City of Renton. June 23 Vicki Morris contacted Phil Schneider to discuss status of his second site inspection, and status report for letter to be written to the City of Renton. Phil stopped by the site for a second time this morning. Oakesdale Avenue SW culvert outlet channel appears to parallel the Springbrook Creek channel for about 75 feet. Still believe there could be fisheries access to the Pierre Grady Way site system. Observed small fish darting in ponded water in depression between ditch culvert outlet and Oakesdale Avenue SW culvert inlet. Electroshocked the pool and found a stickleback*. Requested a copy of the historic aerial photos. (Mailed by Vicki Morris 6/23/97.) Phil has a call in to Ted Muller, his supervisor in Olympia, to discuss the appearance that the ditch system is totally artificial. Additional field observations of the ditch and culvert system, and information gathered thus far have not yet provided conclusive data from which WDFW can draw different conclusions than presented in their letter dated June 1, 1997. I estimate that two to three more weeks may be required for Taylor Associates to complete a letter report. If the City of Renton has, or knows of anyone within Metro who has Springbrook Creek stream gauge or monthly flow duration curve data, it would be very helpful to us to receive a copy of this information. * A stickleback is a very common non-salmonid fish that often occurs in poor water quality and poor habitat conditions where no other species are present.

SUMMARY OF ACTION: Development Services Recommendation: Approve with conditions DEVELOPMENT SERVICES REPORT: The Development Services Report was received by the Examiner on June 3, 1997. PUBLIC HEARING: After reviewing the Development Services Report, examining available information on file with the application,field checking the property and surrounding area;the Examiner conducted a public hearing on the subject as follows: MINUTES The following minutes are a summary of the June 10, 1997 hearing. The legal record is recorded on tape. The hearing opened on Tuesday,June 10, 1997, at 9:00 a.m. in the Council Chambers on the second floor of the Renton Municipal Building. Parties wishing to testify were affirmed by the Examiner. The following exhibits were entered into the record: Exhibit No. 1: Yellow file containing the original Exhibit No.2: Vicinity map application,proof of posting,proof of publication and other documentation pertinent to this request. Exhibit No.3: Site plan Exhibit No.4: Erosion&mitigation plan Exhibit No.5: Interim drainage plan The hearing opened with a presentation of the staff report by MARK PYWELL,Project Manager,Development Services,City of Renton,200 Mill Avenue South,Renton,Washington 98055. The applicant requests James P. &Barbara Lynn Pierre Pierre Fill&Grade File No.: LUA-97-046,SP July 3, 1997 Page 2 approval for fill and grade of a site that is currently vacant and will be importing approximately 15,000 cubic yards of fill material and exporting approximately 2,000 cubic yards of fill material. The Environmental Review Committee(ERC)issued a Determination of Non-Significance on May 13, 1997. On June 4, 1997,the State Department of Fish&Wildlife notified that they will be requiring a hydraulic permit from the applicant. The project site is approximately 2.74 acres. Regarding traffic volume, if 20 cubic yard trucks are used for the project it would require about 100 truck trips for the cut material being removed,and approximately 750 for the fill material. That would generate 850 round trips; however,this number could potentially be reduced if trucks carrying fill material to the site could leave with the export material. Most of the fill material will be coming from the Metro site, so the trucks would be coming down Oakesdale Avenue and would access the site from an Oakesdale Avenue entrance. The remainder will be coming from a site to the south. The site has not been selected for the exported material. The fill and grade operation will not require screening or fencing,or the establishment of special setbacks on this particular project. The applicant will need to hydroseed the site or use other suitable means to ensure that the subject property is not subject to wind or water erosion in the time between the completion of the grading and when a project for the site is approved and construction is started on that project. Noise and dust may be generated during the filling of the subject site. The applicant will need to have temporary erosion controls in place during the grading of the site to prevent dust. The only noise anticipated from this site would be in the use of the equipment itself and not expected to exceed existing City limits. There is existing surface drainage into the ditch which the applicant will be anticipating putting in the piping system. This of course will need to have its final approval on the construction permit. The forebay channel in this area accommodates this site's detention needs. Staff would recommend approval of the special permit for the fill and grade with the conditions contained in the staff report. The Examiner asked if the Fisheries Department intervention on this project was a recent event in this area, and Mr.Pywell responded that this was a new requirement that they had not seen on other projects. He speculated that the concern may have been raised by the proximity of this site to Springbrook Creek. Their concern would mainly be with the quantities and quality of the water coming from this site under that permit. The City believes this is strictly a drainage channel,not a stream. Vicky Morris,Vicky Morris Consulting Services,7732 18th Avenue NE, Seattle,Washington 98115, spoke on behalf of the applicant,and stated that her role regarded environmental compliance and permit applications. She stated that the main construction entrance will be from SW Oakesdale since the majority to be imported to the site will be coming from the north,from the Renton Metro Treatment Plan. The applicant would like to retain the option to possibly develop a secondary entrance on SW Grady Way toward the eastern end of the site to facilitate the circulation of the large trucks as they come and go from the property. She stated that the Washington Department of Fish&Wildlife requirement for hydraulic permit approval on this project was unknown to them until this hearing. There had been no opportunity to inquire about their specific concerns or what may be required with regard to their letter of comment on the project. James P. &Barbara Lynn Pierre Pierre Fill&Grade File No.: LUA-97-046,SP July 3, 1997 Page 3 Cheryl Girard,American Engineering,4032 148th Avenue NE,Redmond,Washington 98052, spoke on behalf of the applicant as the project civil engineer. Regarding the HPA request, she stated that she did not believe the proposed drainage channel actually supports aquatic life,and that their wetlands expert testified to that effect in a report that was included with the environmental checklist. As to the proposed grading,Exhibit 3 identifies grading to the north which extends only up to a 20 foot sanitary sewer easement granted to Metro. The applicant has decided to extend the grading to a point at which it can be sloped 2 to 1 to the property line. This eliminates the requirement for rockery,but it does require that adjustment to a Seattle Metro manhole be approved by Metro. The elevation change to the site is between 2 and 4 feet because the site undulates. All other grading as proposed in the original application remains the same. The proposed storm water conveyance facility consists of two 48 inch pipes and has been designed to handle about 30 percent more than the 100 year flood from both onsite and offsite drainage basins. Responding to the Examiner's questions regarding keeping an open drainage system on the site,Ms. Girard stated that it would make no sense to try and fill the site without enclosing the existing drainage course. It would not be economically feasible to divide it into two sections. Donald Moody, Western Pacific Properties, 16443 SE 35th,Bellevue,Washington 98008, spoke on behalf of the applicant. Regarding leaving the ditch open,he stated that not only does it take up a tremendous amount of space on the property, it also destroys the parking and building patterns on the site. This site also has a power line running down the center. The piece of property was actually purchased based on having it filled. James Pierre, 11525 Lake City Way NE, Seattle,Washington 98125,applicant herein, stated that his intended use of the property is auto related. He has a potential user at this point in time basically for renting and sale of used vehicles. Roughly 280 parking places is needed, so any altering of the space would be a real detriment. Neil Watts,Plan Review Supervisor,Development Services,City of Renton,200 Mill Avenue South,Renton, Washington 98055, addressed the drainage plan and the proposed twin 48 inch storm lines. They will provide more than adequate capacity for the upstream area which is largely developed at this time, and if anything they are oversized for the limited basin that comes into this. Regarding the open ditch,applicant is looking at fills in the neighborhood of 20 to 21 foot elevation which roughly brings it up to elevation with Grady. The existing inverts for the drainage system now are about 9 where it comes into the site at Powell and about 6 feet of elevation where it leaves. That would be a fairly deep ditch and would take up a large portion of the site. Mr. Watts suggested that the applicant find out what Fisheries was concerned about, and that hopefully it would be temporary erosion control and water quality treatment which have already been addressed. The Examiner at this point closed the public hearing,but kept the matter open for two weeks. During this time applicant and staff were to communicate with Fisheries to see what their position was. At that time he would issue a decision subject to information received from the parties. The hearing closed at 9:40 a.m. FINDINGS,CONCLUSIONS&DECISION Having reviewed the record in this matter,the Examiner now makes and enters the following: James P. &Barbara Lynn Pierre Pierre Fill&Grade File No.: LUA-97-046,SP July 3, 1997 Page 4 FINDINGS: 1. The applicant,James P. and Barbara Lynn Pierre,filed a request for approval of a Special Permit to fill and grade an approximately 2.74 acre site. 2. The yellow file containing the staff report,the State Environmental Policy Act(SEPA)documentation and other pertinent materials was entered into the record as Exhibit#1. 3. The Environmental Review Committee(ERC),the City's responsible official, issued a Declaration of Non-Significance(DNS)for the subject proposal. 4. The subject proposal was reviewed by all departments with an interest in the matter. 5. The subject site is located along the north side of SW Grady Way between Oakesdale Avenue SW on the west and Powell Avenue SW on the east. 6. The subject site is an odd, inverted T-shaped parcel. The parcel appears like two rectangular parcels stacked on one another with the smaller rectangle centered atop the longer, larger one. It has approximately 720 feet of frontage along Grady Way, its southern boundary. It is approximately 80 feet deep at its east boundary. It widens to approximately 240 feet for its center third and then narrows to approximately 160 feet at its west boundary. 7. The subject site is zoned CO(Commercial Office), a category assigned in June 1993 with the adoption of Ordinance 4404. 8. The subject site was annexed to the City with the adoption of Ordinance 1745 enacted in April 1959,as amended by Ordinances 1764 and 1928 enacted in May 1959 and December 1961,respectively. 9. The map element of the Comprehensive Plan designates the area in which the subject site is located as suitable for the development of employment generating uses,but does not mandate such development without consideration of other policies of the Plan. 10. The area is developed with a variety of uses including automobile sales,office and commercial uses and some industrial uses. 11. The site is currently vacant. It does not contain any significant trees or vegetation. A large drainage ditch runs through the center of the property from east to west. The bottom of the ditch is approximately 4 feet below the current grade of the site. A 20 foot wide Metro sewer easement runs east to west across the northern edge of the parcel. A power line transmission line also runs east to west across the site. 12. Approximately 2 to 4 feet of fill material will be imported to the site to create a level grade. The plans were altered and fill material will be placed over the sewer line and graded to create a gentle slope. The original plans called for an abrupt end supported by a rockery to avoid placing fill over the sewer line. 13. The applicant proposes diverting the storm water from the ditch to two 48 inch culverts and filling the site over these culverts. Staff reports that this conveyance will provide sufficient capacity to handle the storm water from the current ditch's drainage basin. James P. &Barbara Lynn Pierre Pierre Fill&Grade File No.: LUA-97-046,SP July 3, 1997 Page 5 14. The Washington Department of Fish and Wildlife has informed the City that a hydraulics permit will be needed for any alteration to the ditch. They have also noted that this ditch feeds the Springbrook Creek and P-1 Channel and might support fish habitat. They recommended that the ditch should be studied further and that it possibly should not be culverted. This information was revealed after City review and neither the applicant nor the City had a chance to review this information. 15. The wetlands report and other reports prepared for the project do not reveal that this ditch currently supports any valuable fish species. It is a not a natural creek and is already culverted both east and west of the site, including under Oakesdale west of the site. Also the gradient is such that at low water periods the creek is perched above its outfall and would probably strand fish. 16. Subsequent to the close of the public hearing,the applicant reanalyzed the hydrology and found during electro-shocking one stickleback. This species apparently is found in poor quality water. 17. The record reveals that a sizable portion of the site would be unusable if the ditch were not culverted, with land lost to the ditch and the necessary side slopes to create stable banks. Exact numbers were not available at this review. 18. The applicant will export approximately 2,000 cubic yards of unsuitable materials from the site and import approximately 15,000 cubic yards of clean fill. The material will raise the grade between 2 and 4 feet depending on the existing undulations on the site. As noted,the ditch would be culverted and covered. 19. Depending on how the exported materials and imported materials are coordinated,approximately 750 to 850 20-ton dump truck trips will be needed to move the materials. If trucks importing materials can be used to remove materials,the lesser number would result. 20. The haul route for the site will be via SW Grady Way and SR 167. Originally,one driveway was specified for truck ingress and egress. The applicant would like an option to use two driveways for circulation. 21. Specific reuse of the site was not defined. 22. Detention is not required on this site but water treatment will be required to maintain the quality of any water directed into the system. Quality treatment will be required with site development. Erosion control will be required during grading. If development does not occur imminently,hydroseeding will be required after the new soils have been placed on the site. CONCLUSIONS: 1. The proposed grade and fill appears to serve the public use and interest, ignoring for the moment the issue of culverting the drainage ditch. The site is below the grade of the surrounding property and more particularly the grade of Grady Way,the adjacent street. This makes access to the site more difficult. 2. Clearly,the site could be leveled below the surrounding terrain,but filling this site without wetland habitat does not appear to create any harm. Clearly,another reason to fill and grade the site was to "bridge"the area of the drainage ditch. By routing the storm water through a culvert system and creating a consolidated parcel,there will be substantially more property to accommodate development. James P. &Barbara Lynn Pierre Pierre Fill&Grade File No.: LUA-97-046,SP July 3, 1997 Page 6 Bisected as it is by an approximately four foot deep drainage ditch makes it unfeasible to develop the property. 3. This office will not judge the merits of keeping the ditch open rather than culverting it,but the information now available does not appear to support the theory that this reach of the ditch supports or can support spawning salmon or trout. The ditch is culverted on both sides of the subject site and due to a change of gradient appears to create unlinked puddles which could strand fish. The WDFW will have to make the final determination on both the hydraulic permit and whether a culvert system can be utilized on this site. This decision will be conditioned to allow the culvert if it receives State approval. 4. The operation is not particularly large but it will necessitate approximately 750 to 850 truck trips and these will have to be accommodated in these busy corridors of Grady and Oakesdale. The specified haul route will keep vehicles along Grady and SR 167 and the hours and days may be limited by the City as it determines. 5. The applicant will have to prevent erosion according to the normal requirements, and the site will have to be hydroseeded to prevent fugitive dust or erosion if the site is not quickly redeveloped. 6. In conclusion, it appears that filling and grading the site is appropriate and will not adversely impact neighboring properties or the natural environment. DECISION: The Special Permit to excavate,fill and grade the subject site is approved subject to the following conditions: 1. The applicant may install a culvert to divert the drainage ditch subject to the approval of the appropriate state agencies. 2. The applicant shall hydroseed the site and take other appropriate actions to prevent fugitive dust or erosion if the site is not redeveloped within two(2)months of the completion of the fill and grade operation. 3. The City shall have sole discretion as to the selected haul route and the hours and days of operation. ORDERED THIS 3rd day of July, 1997.

June 10 Applicant and applicant's representatives first made aware of WDFW letter at Fill and Grade Permit hearing. Hearing Examiner left the record open on this decision until June 24, 1997, pending additional communications with WDFW. June 10 Telephone message left for Phil Schneider, WDFW Fisheries Habitat Biologist, by Vicki Morris, Environmental Consultant, applicant's representative. Requested the opportunity to discuss his letter. June 11 Bill Taylor, Taylor Associates, Fisheries Biologist and Aquatic Scientist, contacted by Vicki Morris to discuss WDFW letter of comment and additional information needed. June 12 Pierre Grady Way Fill and Grade project information provided to Bill Taylor. June 12 Phil Schneider returned call to Vicki Morris. Discussed his observations of potential for fish access to the Pierre Grady Way site ditch: potential winter time side channel rearing habitat. Discussed possible sources for the additional information he is seeking. Identified Comprehensive Fisheries Assessment of the Mill Creek, Garrison Creek and Springbrook System prepared by Harza for the City of Kent(1995). June 12 Telephone message left for Bill Walinski, City of Kent Public Works Department, by Vicki Morris, requesting a copy of the Mill Creek Fisheries Assessment. June 12 Bill Taylor retained to conduct additional information gathering requested by Phil Schneider. June 12 Bill Taylor talked with Phil Schneider. Discussed appearance of hydraulic function of the system, types of information to be gathered for confirmation of hydraulic function, and possible alternatives to culverting and filling the ditch that may be required by HPA. 7732 18TH AVENUE NORTHEAST • SEATTLE,WA 98115-4426 • FAX: (206) 523-4648 • PHONE: (206) 522-8057 11 Mark Pywell/Vicki Morris Re: Pierre Grady Way Site, LUA 97-046, SP June 24, 1997 • June 13 Vicki Morris contacted Phil Schneider to request a meeting with applicant's representatives. June 14 Site visit by Vicki Morris and Bill Taylor to inspect the system: onsite ditch muddy, no standing water except near outlet culvert; discontinuous connection to Oakesdale Avenue SW culvert(two separate culverts with depression in between, ±1 ft drop between ditch bottom and ditch outlet culvert); and indistinct side channel between Springbrook Creek main channel and Oakesdale Avenue SW culvert. Noted opportunities for fry stranding if system flow was discontinuous during fish presence in these areas. June 16 Meeting in Eastgate: Phil Schneider,Don Moody, Bill Taylor, Vicki Morris to discuss issues, concerns and observations; and data to be collected. Discussed potential absence of WDFW jurisdiction/interest if the ditch is a totally artificial system that only flows during storm events. June 17 Significant rain storm mid-day. Taylor Associates field crew at site to take flow measurements. Anecdotal observations: Don Moody at the site 3:30 PM when the rain stopped. Water was flowing 18 inches to 2 ft deep in the ditch at that time. Returned to the site at 4:30 PM; flow was approximately the same. Returned to the site the next day, 6/18/97, at approximately 11:00 AM—the ditch was not flowing at all. June 17-23 Taylor Associates field work: collecting water stage(water surface elevation) versus discharge information to provide an estimate of Springbrook Creek flow at the point when it would enter the Oakesdale Avenue SW culvert and create a hydraulic connection with the Pierre Grady Way site system. Looking for Springbrook Creek monthly flow duration curves to estimate the amount of time the creek is high enough to provide easy access to the site culvert and ditch. Data collected todate: 3 flow measurements (including one very high flow following 6/17/97 storm); and cross-sectional profile of Springbrook Creek channel to invert of Oakesdale Avenue SE culvert, and to invert of Pierre Grady Way site ditch culvert. June 18 Richard Chase, City of Kent Public Works Department, returned call to Vicki Morris. Offered to loan a copy of the Mill Creek Fisheries Assessment. June 19 Vicki Morris picked up the Mill Creek Fisheries Assessment from the City of Kent. Also stopped at Walker& Associates (Tukwila)to review historical aerial photograph record (1936-1995). Historical photos show ditch parallel to railroad embankment for the entire period of record; i.e., it appears to have been excavated at the time of railroad construction. Vicki Morris provided a copy of the Mill Creek Fisheries Assessment and historic aerial photos to Bill Taylor. An appendix to the Mill Creek Fisheries Assessment contains only a limited amount of USGS stream gauge data. 2 Mark Pywell/Vicki Morris Re: Pierre Grady Way Site, LUA 97-046, SP June 24, 1997 • June 19 Telephone calls to Bill Taylor,Phil Schneider and Don Moody by Vicki Morris to advise of findings in historical aerial photo review: ditch appears to have been artificially created. June 20 Telephone calls to Bill Taylor and Phil Schneider by Vicki Morris to request status reports for letter to be written to the City of Renton. June 23 Vicki Morris contacted Phil Schneider to discuss status of his second site inspection, and status report for letter to be written to the City of Renton. Phil stopped by the site for a second time this morning. Oakesdale Avenue SW culvert outlet channel appears to parallel the Springbrook Creek channel for about 75 feet. Still believe there could be fisheries access to the Pierre Grady Way site system. Observed small fish darting in ponded water in depression between ditch culvert outlet and Oakesdale Avenue SW culvert inlet. Electroshocked the pool and found a stickleback*. Requested a copy of the historic aerial photos. (Mailed by Vicki Morris 6/23/97.) Phil has a call in to Ted Muller, his supervisor in Olympia, to discuss the appearance that the ditch system is totally artificial. Additional field observations of the ditch and culvert system, and information gathered thus far have not yet provided conclusive data from which WDFW can draw different conclusions than presented in their letter dated June 1, 1997. I estimate that two to three more weeks may be required for Taylor Associates to complete a letter report. If the City of Renton has, or knows of anyone within Metro who has Springbrook Creek stream gauge or monthly flow duration curve data, it would be very helpful to us to receive a copy of this information. * A stickleback is a very common non-salmonid fish that often occurs in poor water quality and poor habitat conditions where no other species are present.

Dear Mr . Pywell : I apologize for my late response . My comments and concerns regarding this checklist for this fill proposal and the further development of the site are as follows : 1 . Page 4 No . 10- We will require a Hydraulic Project Approval for the installation of the 670 feet of 48" diameter pipe in this Tributary to Springbrook Creek and for the discharge of stormwater . In addition,due to its proximity and lack of fish blockages from Springbrook Creek,the channel that is proposed to be tightlined, may provide off channel rearing opportunities for juvenile salmon. More information in needed regarding fish use in this channel especially during the winter months . 2 . Page. 4 No . 11- The Department of Wildlife will require that the storm water discharge meet the Department of Ecology Stormwater Manual for Puget Sound for both quantity and quality. The storm water from this site directly discharges into Springbrook Creek which support both salmon and trout . Thank you for the opportunity to comment on this proposal . If you have any questions please call me at ( 425) 391-4365 . We appreciate your cooperation in our efforts to protect and perpetuate our fish and wildlife resources .

APPLICABLE SECTIONS OF THE COMPREHENSIVE PLAN: 1. Land Use Element, Employment Area Valley G. DEPARTMENT ANALYSIS: 1. PROJECT DESCRIPTION/BACKGROUND The project site is currently vacant. The subject property slightly lower than the surrounding streets and the adjacent developed lots. On-site drainage flows overland to an existing drainage channel that leads into the area storm water system. It is anticipated that the proposed grading will not increase the quantity of rate of existing storm water flows. The applicant intends to import 15,000 cubic yards of fill and to export 2,000 yards of material. The export material will consist mostly of organic material scraped from the surface of the site. No significant trees or shrubs are located on this site. 2. ENVIRONMENTAL REVIEW Pursuant to the City of Renton's Environmental Ordinance and SEPA (RCW 43.21C, 1971 as amended), on May 13, 1997 the Environmental Review Committee issued a Determination of Non-Significance. 3 COMPLIANCE WITH ERC MITIGATION MEASURES No mitigation measures required. 4. STAFF REVIEW COMMENTS Representatives from various city departments have reviewed the application materials to identify and address site plan issues from the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of the report. PRELMRPT.DOC City of Renton P/B/PW Department Preliminary Report to the Hearing Examiner PIERRE FILL 8 GRADE LUA-97-046, SP PUBLIC HEARING DATE: June 10, 1997 Page 4 of 5 5. CONSISTENCY WITH SPECIAL PERMIT FOR FILL & GRADE APPROVAL CRITERIA Section 4-10-3 (B.) "As provided in the Zoning Ordinance, the Hearing Examiner may grant a special permit to allow drilling, quarrying, mining, or depositing of minerals or materials, including but not limited to petroleum, coal, sand, gravel, rock, clay, peat and topsoil. A special permit shall be granted prior to the Public Works Department issuing any annual license as concurred with by the Building Department and authorized by this Ordinance." "Compatibility of Proposed Uses: To grant a special permit, the Hearing Examiner shall make a determination that the activity would not be unreasonably detrimental to the surrounding area. The Hearing Examiner shall consider, but is not limited to, the following:" (1) SIZE AND LOCATION OF THE ACTIVITY The project site is located along the North side of SW Grady Way, extending from Oakesdale Ave. SW on the West to Powell Ave. SW on the East. The project site includes 119,521 sf (2.74 acres). The applicant intends to import 15,000 cubic yards of fill material after removing approximately 2,000 cubic yards of material that is unsuitable for supporting structures. (2) TRAFFIC VOLUMES AND PATTERNS If 20 cubic yard trucks are used on this project, it is anticipated that the removal of the 2,000 cubic yards of material will generate 100 round-trip truck trips and the importing of the fill material will generate 750 round-trip truck trips for a total of 850 round-trips. It is possible that the trucks importing the fill material could also be used to remove the material designated for export. Trucks will access the site from SW Grady Way. To access the project site, trucks will follow SR 167 to SW Grady Way. Trucks leaving the project site will follow the same route in reverse. (3) SCREENING, LANDSCAPING, FENCING, AND SETBACKS The fill and grading operation will not require screening, fencing, or the establishment of special setbacks. As the applicant has not submitted a site plan or other land use permit with the Special Permit for Fill & Grade, the applicant will need to hydro-seed or use other suitable means to ensure that the site is not subject to wind or water erosion in the time between the completion of the grading and the construction of a particular use. The applicant has proposed several future uses of the site that are compatible with the Zoning and Comprehensive Plan designation for the subject property. However, the timing of the submittal of the necessary permits and the subsequent review is unknown at this time. It is anticipated that they will be submitted this year. (4) UNSIGHTLINESS, NOISE AND DUST • Noise and dust may be generated during the filling of the subject site. Noise will be generated from the trucks used to haul the fill material and from the grading equipment. It is not anticipated that the noise levels will exceed the standards established by the City of Renton Municipal Code. Dust will be controlled as required by sprinkling the subject property. Once the grading is completed the applicant will need to hydro-seed the site or take other steps, approved by the City, to control the dust. PRELMRPT.DOC City of Renton P/B/PW Department • Preliminary Report to the Hearing Examiner PIERRE FILL 8 GRADE LUA-97-046, SP PUBLIC HEARING DATE: June 10, 1997 Page 5 of 5 (5) SURFACE DRAINAGE At this time the drainage sheet flows across the site and flows into an existing drainage ditch that joins into the existing City storm system for this area. The applicant will need to maintain the existing drainage ditch unless plans for piping the flow of storm water is approved as part of the constructions plans for this site. Past agreements with previous land owners that are still in effect have addressed the need for storm water detention in this area. (6) THE LENGTH OF TIME THE APPLICATION OF AN EXISTING OPERATION HAS TO COMPLY WITH NONSAFETY PROVISIONS OF THIS ORDINANCE. (ORDINANCE 2820, 1-19- 74; AMENDED BY ORDINANCE 3098, 12-17-76, EFFECTIVE 1-26-77) Not applicable to this project. H. RECOMMENDATION: Staff recommends approval of the Pierre Special Permit for Fill & Grade, Project File No. LUA-97- 046 subject to the following conditions: (1) The applicant will need to maintain the drainage ditch across the subject property unless plans for the piping of the storm water flows is approved by the Development Services Department as part of the construction drawings for this'site. (2) The applicant will need to hydro-seed or otherwise stabilize the site to prevent dust and erosion immediately following the completion of the grading operation. EXPIRATION PERIODS: Special Permit and Special Fill & Grade Permits (SP): Two (2) years from the final approval (signature) date.

ENVIRONMENTAL IMPACTS In compliance with RCW 43.21 C. 240, the following project environmental review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. Whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development? 1. Earth Impacts: The applicant intends to fill and grade the subject property in order to create a suitable building site for a future project. The applicant is currently considering several opportunities for this site but no decision has been made at this time. When the applicant is sure which project proposal will be constructed, a separate application and environmental review will need to be submitted. In any event the site needs to be filled in order to allow for future construction to occur at the same elevation as the surrounding area. The applicant will need to first clear the existing vegetation, mostly grasses and small bushes, and then bring in fill that is appropriate for construction activities. This will require the removal of approximately 2,000 cubic yards of material and the importation of 15,000 cubic yards of soil. It is estimated that this will require approximately 850, round-trip,truck trips during the grading operation for this site. Mitigation Measures: No further mitigation required beyond the Code requirements. Nexus: N/A 2. Air Impacts: Air quality impacts will be limited to fugitive dust during the grading operation and potential from the disturbed area between the completion of the grading operation and the actual construction of the building or other structures on the site. Fugitive dust can easily be controlled through the sprinkling of the site during the grading operation. Once grading is completed, if no construction will commence within 30 days existing Code language requires the applicant will need to hydro-seed the site or use other methods to prevent fugitive dust until such time as the site is fully developed. Impacts to the air quality may also be associated with the exhaust from vehicles and equipment used during the grading phase of the project. These impacts are already regulated by regional, state, and federal regulations. No further mitigation is necessary for the equipment or vehicles anticipated to be used for this project. Mitigation Measures: No further mitigation is required. Nexus: N/A 3. Water Impacts: There is a open drainage ditch that crosses this site. This is part of an existing storm water system that is contained within culverts on both sides of the property. The applicant will either need to install a pipe system for this drainage system as part of the grading operation or alternatively the applicant could maintain the ditch until they are ready to construct the culvert system. This issue will be further addressed in the Hearing Examiner report. Mitigation Measures: No mitigation measures are required.

Wetlands Impacts: There are low portions of the site that City staff felt needed to be investigated. Also there are known wetlands further to the north and west. An investigation of the site was conducted by John Comis Associates in September, 1996. The conclusion of this on-site wetland review was that there are no areas on this site that demonstrate the characteristics of wetlands. Mitigation Measures: No mitigation measures are required. Nexus: N/A E. COMMENTS OF REVIEWING DEPARTMENTS The proposal has been circulated to City Departmental/Divisional Reviewers for their review. Where applicable, these comments have been incorporated into the text of this report as Mitigation Measures and/or Notes to Applicant.

An Environmental Impact Statement (EIS) must be prepared for all proposals with probable significant adverse impacts on the quality of the environment. The purpose of this checklist is to provide information to help you and the agency identify impacts from your proposal (and to reduce or avoid impacts from the proposal, if it can be done) and to help the agency decide whether an EIS is required. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Governmental agencies use this checklist to determine whether the environmental impacts of your proposal are significant, requiring preparation of an EIS. Answer the questions briefly, with the most precise information known, or give the best descriptions you can. You must answer each question accurately and carefully, to the best of your knowledge. In most cases, you should be able to answer the questions from your own observations or project plans without the need to hire experts. If you really do not know the answer, or if a question does not apply to your proposal, write "do not know" or "does not apply". Complete answers to the questions now may avoid unnecessary delays later. Some questions ask about governmental regulations, such as zoning, shoreline, and landmark designations. Answer these questions if you can. If you have problems,the governmental agencies can assist you. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact.

Do you have any plans for future additions, expansion, or further activity related to or connected with this proposal? If yes,explain. Pierre Grady Way site development is proposed in two phases. The owner initially proposes to apply for a City of Renton Grade and Fill Permit (April 1997). A nearby source of suitable, inexpensive fill will be available from construction scheduled to occur at the Metro Renton sewage treatment plant approximately one-half mile northwest of the Pierre Grady Way site. This fill will be available in Summer 1997, before the Rezone and Site Plan Approval processes could be completed to permit site development for automobile sales, service and/or rental uses, as proposed. Regardless of the outcome of the land use decision, filling this site to a grade compatible with the adjacent street system is important to it's future development and productive use. Within weeks after submitting the Grade and Fill Permit application, the owner plans to submit a consolidated application for Rezone and Site Plan Approval, to pursue actual development plans for the site. A separate Environmental Checklist will be prepared to address characteristics of the specific development proposal in more detail. 8.

Do you know whether applications are pending for governmental approvals of other proposals directly affecting the'property covered by your proposal? If yes,explain. There are no applications pending for governmental approvals of other proposals directly affecting the property involved in the Pierre Grady Way site proposal. 10. List any government approvals or permits that will be needed for your proposal,if known. Permits/Approvals Required for Permits/Approvals Required for Site Grading and Filling Site Development Rezone from Commercial Office(CO) City of Renton Grade and Fill Permit to Medium Industrial(1M) City of Renton Construction Permit Site Plan Approval Environmental Review Environmental Review Engineering Plan Approval Construction Permits: Utilities and Site Work Building Permit 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. At the time of this application, the proposed action is to clear, grade and fill the Pierre Grady Way site, and construct the subsurface drainage conveyance system. Approximately 15,000 cu yd of fill is required to bring the site up to a compatible elevation with adjacent streets. (It is presently 3 to 5 feet below surrounding street elevations.) An abandoned railroad grade fill on the northern parcel (10 to 14 feet above the elevation of the remainder of the site)will be graded to blend with the finished elevation. Offsite stormwater conveyance through the property will be provided in two 670-ft lengths of 48- inch diameter corrugated metal pipes (CMPs) to be installed in the bottom of the drainage channel. The permanent subsurface drainage system will be designed to convey the calculated surface water flow of both on- and offsite developed conditions during a 100-year, 24-hour storm event. Drainage collection structures and biofiltration swales will be installed at various locations in the completed development. The collection structures will be designed to split the 2-year, 24-hour flows to biofiltration swales. All other site runoff entering the proposed drainage collection system will be directed to the 48-inch diameter culvert to be installed in the south side of the existing drainage channel. The 48-inch diameter culvert to be installed on the north side of the channel will convey the entire offsite flow and provide additional flood storage, if required. The existing open drainage channel will be filled after installation of the twin 48-inch CMPs. A City of Renton/Puget Western, Inc. Agreement and Easement (May 16, 1985) related to this drainage channel allows filling and construction of improvements over the easement area(Section 3). No surface water detention is proposed due to the proximity of the site to the low end of the drainage sub-basin. The developed condition 100-year, 24-hour storm event flow from the site is calculated to be 2.35 cubic feet per second (cfs), compared to the total pre-developed 100-year, 24- hour event surface water flow of 1.74 cfs. The net increase in 100-year, 24-hour storm event surface Pierre Grady Way Site SEPA Checklist 4/04/97 4 water flow is thus projected to be approximately 0.61 cfs. The downstream conveyance system has ample capacity to convey this runoff without flooding. The property owner is released from drainage retention, compensating storage and floodplain requirements by the Agreement and Easement for Drainage(May 16, 1985; Section 13). Application is being made for a City of Renton Grade and Fill Permit in advance of Site Plan Approval for development due to the availability of suitable, inexpensive fill from a source within one- half mile of the site. This fill will be available before site development approvals and construction permits could be obtained. The development process has been initiated (see City of Renton Pre- Application File #97-12), and will be pursued by the owner soon after the Grade and Fill Permit application. The likely development scenario at this time is a three-story, 15,000 sq ft office building (5,000 sq ft footprint)to be constructed in the southwest corner of the site, with parking for 280 to 290 cars(see Figure 1). Foundation piles and a structural slab may be used to support this structure (American Engineering Corporation, April 1997a). Alternatively, a 20,000 sq ft single-story building may be constructed on the northern parcel, with 200 to 225 parking spaces. It may be possible to construct a building of this configuration on wide spread footings in the fill, if bearing loads are low. The specific development scenario will be addressed in more detail in an Environmental Checklist to be submitted with a consolidated Rezone and Site Plan Approval application. Three new points of driveway access to the site are proposed: two from SW Grady Way, and one from Oakesdale Avenue SW(see Figure 1). Public right-of-way landscaping and onsite landscaping will be provided in accordance with City of Renton requirements. The owner/applicant proposes to develop an automobile sales, service and/or rental use on the property. A prospective tenant is Enterprise Rent-a-Car, who may develop a regional facility on the Grady Way site. Alternatively, Mr. Pierre may use the property for an automobile dealership. Enterprise would utilize office space on the site, and may engage in car rentals, maintenance and/or used car sales at this location. An automobile dealership would engage in new and/or used car sales and service. The development proposal will be addressed in more detail in a subsequent application and Environmental Checklist. 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The Pierre Grady Way site is located on SW Grady Way between Oakesdale Avenue SW and Powell Avenue SW in the City of Renton (see Figure 2). A lengthy legal description of the site is provided with the Master Application. Parcels A, B, C, D, E and F are located in the Northeast 1/4 of Section 24, Township 23 North,Range 4 East,W.M.,King County, Washington.

General description of the site (underscore one): Flat, rolling, steep slopes, mountainous, other b. What is the steepest slope on the site(approximate percent slope)? The site is generally flat, with 0.5 percent to 1 percent slope overall. The side slopes of the open drainage channel through the site are 1:1 (horizontal to vertical). The incised drainage channel is 4 to 6 feet deep. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The site is located in a lowland that has been filled over time. Historic (1973) U.S. Soil Conservation Service(SCS)maps identify site soils as Renton silt loam (Re)with nearly level to gently undulating topography, and Puyallup fine sandy loam (Py)'— a moderately well-drained soil in valley bottoms with slopes less than 2 percent. SCS lists the Renton and Puyallup series as non-hydric (upland) soils. Other soil types included within this map unit are: as much as 15 percent Biscott and Pilchuck soils, and some poorly drained Seattle muck in depressions (John Comis Associates, September 1996). A site-specific Geotechnical Engineering Investigation was conducted by American Engineering Corporation (April 1997a) to evaluate foundation soils and provide recommendations concerning the geotechnical engineering aspects of site conditions. Site soils are classified in this report using the Unified Soils Classification System (USCS). A dense mat of organic debris (cut and trampled blackberry vines and Scot's broom) covers the majority of the surface of the site, as thick as 12 inches in places. Surficial soils are marginally plastic, silty clay to a depth of about 12 feet. This soil mantles practically the entire site. Surficial soils are classified as Hydrologic Group C soil, with a moderate to high runoff potential. The silty clay is underlain by a thick layer of loose to dense, saturated silty sand that extends to a depth of 25.5 to 27.5 feet in the area proposed for the three-story building(southwest corner of the site). Soils above 27 feet were deposited by streams and flood waters of the abandoned Black River channel west of the site that used to drain Lake Washington. Soils encountered below 27 feet are believed to be glacial outwash deposits. Very dense, gravelly sand was encountered between 27 feet and the greatest depth penetrated: 51.5 feet. No bedrock was encountered in the eight test holes drilled on the site. It is expected that the bedrock layer is more than 100 feet below ground surface(American Engineering Corporation, April 1997a). An Environmental Site Assessment was conducted in the area of the former railroad embankment on the site (northern parcel). Test pits were advanced to a depth of approximately 15 feet below Pierre Grady Way Site SEPA Checklist 4/04/97 8 ground surface (bgs) through the railroad right-of-way. Soils in this area of the site have generally been described as follows(Environmental Hazards Control, September 1996): 0 to 3 feet 1-inch to 3-inch rock/railroad ballast 3 to 11-14 feet Coal slag, ash and ballast 11 to 15 feet Clay sands d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. Seattle is situated in a moderately active earthquake region where the Juan de Fuca plate is thrust beneath the North American plate along the toe of the continental slope (Galster and Laprade, August 1991). The Unified Building Code(1994 Edition) places the Puget Sound area within Seismic Zone III, which indicates significant seismic risk. The design level earthquake for this zone is magnitude 7.0 to 7.5 with peak ground acceleration of about 0.3g. Liquefaction occurs when loose, saturated and relatively cohesionless soil deposits temporarily lose strength as a result of earthquake shaking. Primary factors controlling the occurrence of liquefaction include intensity and duration of strong ground motion, characteristics of subsurface soil, in-situ stress conditions, and depth to groundwater. Due to the flatness of the Pierre Grady Way site, there is no evidence of landslide or erosion hazards. The thick layer of loose to dense, saturated silty sand that occurs 12 to 27.5 feet below ground surface is potentially liquefiable under seismic load;however, pore pressure dissipation rates are favorable to the extent that liquefaction potential is slight (American Engineering Corporation, April 1997a). e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. The Phase 1 proposal is to place approximately 15,000 cu yd of fill on the site to raise the elevation for compatibility with adjacent City streets and surrounding parcels. The majority of the site is approximately 3 feet below this grade at the present time. The preferred source of fill is excess material to be removed from the Metro Renton sewage treatment plant site in the Summer of 1997. This fill source site is approximately one-half mile northwest of the Pierre Grady Way site on Oakesdale Avenue SW. The site-specific Geotechnical Engineering Investigation report prepared for this project (American Engineering Corporation, April 1997a) extensively describes compaction requirements and fill control measures to create a structural fill with the material to be placed on the site. Depending on the type of structure to be built, bearing loads and foundation type selected, surcharge material and additional select fill may be imported for specific purposes. Pierre Grady Way Site SEPA Checklist 4/04/97 9 Approximately 1,200 cu yd of select gravel bedding material will be imported for use around 48- inch diameter corrugated metal pipes to be installed in the drainage channel to underground this stormwater conveyance system. f. Could erosion occur as a result of clearing,construction, or use? If so,generally describe. Clearing, grubbing, grading and filling the site will expose soils to increased erosion potential by wind and rain during the temporary earthwork phase. g. About what percent of the site will be covered with impervious surfaces after project construction (for example,asphalt or buildings)? No impervious surfaces will be introduced on the site as a result of the clearing, grading and fill action. h. Proposed measures to reduce or control erosion,or other impacts to the earth,if any: Earthwork and installation of corrugated metal pipes in the existing drainage channel will be scheduled to occur during the driest weather possible to minimize the potential for siltation in the existing drainage system. Best Management Practices to be implemented during the temporary earthwork phase include placement of filter fabric fences, temporary sediment traps, temporary ditches, and controlled grading; revegetating the site within 15 days after the placement of fill;and placing crushed rock or quarry spalls at construction entrances and exits to minimize tracking mud and dust offsite. Regrading new slopes to catchment facilities will reduce soil saturation. 2. AIR a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. There will be dust and construction vehicle exhaust emissions to the air during the temporary earthwork and construction phases. Vehicular emissions will not be dissimilar to air quality in the general vicinity, due to the location of the site adjacent to arterial streets and near the I-405 and SR- 167 freeways(see Figure 2). b. Are there any offsite sources of emissions or odor that may affect your proposal? If so, generally describe. The Pierre Grady Way site is located within one-half mile of the Metro Renton sewage treatment plant on Oakesdale Avenue SW. When the wind direction is out of the northwest, it is possible that Pierre Grady Way Site SEPA Checklist 4/04/97 10 treatment plant odors would be noticeable on the site. These odors would have no affect on the proposed grade and fill action. c. Proposed measures to reduce or control emissions or other impacts to air,if any: The magnitude of potential air quality impacts attributable to the project does not warrant a significant mitigation effort. Contractors will be required by contract terms to implement standard construction practices for dust suppression and cleaning dust from public roads, if necessary. 3. WATER a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year- round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate,state what stream or river it flows into. A City of Renton drainage channel traverses the site in an east-west direction (see Figure 1). The channel ranges from 4 to 6 feet deep, is 2 feet wide at the bottom, with side slopes of 1H:1V, and a bed slope of approximately 0.007 feet per foot. The grass-lined channel conveys seasonal offsite flow at an average depth of approximately 6 inches during winter (wet) months. Offsite contribution to the drainage channel consists of mostly undetained surface flow from a 44-acre upstream basin which enters the site via twin 48-inch diameter corrugated metal pipe (CMP) culverts, and exits the.site (beneath Oakesdale Avenue SW) via approximately 189 lineal feel (lf) of 66-inch diameter CMP culvert (American Engineering Corporation, April 1997b). At this point, additional surface flow from approximately 9,400 sq ft (0.22 acre) of paved area is collected and added to the total conveyance volume. The 66-inch CMP outfalls to a 20-ft wide by 40-ft long rip rap pad. The rip rap pad reduces flow velocity and erosion potential where surface flow from the 47-acre total basin(the upstream basin plus the Pierre Grady Way site)joins the P-1 Drainage Channel. At this location in the channel, it appears the P-1 may convey surface water runoff from several thousand acres(a portion of the historic Black River drainage basin)to it's outfall near the Metro Renton sewage treatment plant. The City of Renton P-1 channel conveys the surface water flows of the lower reach of Springbrook Creek. The site was examined for jurisdictional wetlands and none were found (John Comis Associates, September 1996). 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes,please describe and attach available plans. The grade and fill proposal includes installing two 670-ft lengths of 48-inch diameter corrugated metal pipe to convey offsite drainage through what is now an open drainage channel, and filling this channel to create useable site area. In the Agreement and Easement for Drainage (May 16, 1985) executed between the City of Renton and Puget Western, Inc. (former property owner), Puget Pierre Grady Way Site SEPA Checklist 4/04/97 11 Western reserved the right for itself and successors to construct improvements, such as buildings, parking and landscaping, over portions of the easement area. No work is proposed within 200 feet of the P-1 channel. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. Enclosing the existing drainage channel in two 48-inch diameter corrugated metal pipes (CMP) and filling the channel will involve installation of approximately 1,360 lineal feel of CMP (two 670-ft lengths), and placement of approximately 1,200 cu yd of imported pipe bedding and cover material. A local quarry to be selected by the contractor is the likely source of pipe bedding material. Cover material is available both onsite and from the Metro Renton treatment plant source. No dredge material will be placed in or removed from surface water or wetlands. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. If site filling and grading occurs during summer months as proposed, it is unlikely that surface water diversion will be required. If there is surface flow in the drainage channel during construction, some minor diversion would need to occur to prevent sediment from entering surface water flows downstream of the project site. The withdrawal location would be on the east side of Powell Avenue SW. The discharge location would be at the existing 66-inch CMP outfall to the P-1 channel. Portable pumps would be sized to convey no less than 20 gallons per minute. 5) Does the proposal lie within a 100-year floodplain? If so, note location on the site plan. Historic Federal Emergency Management Act (FEMA) maps indicate that a portion of the west side of the Pierre Grady Way site may once have been at the 100-year floodplain elevation. The P-1 channel 100-year flood elevation at the project site outfall appears, from available information, to be approximately +15 feet. Surface evidence of high water marks and historic reports associated with recent flooding events do not indicate that the site is within a 100-year floodplain. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. There will be no intentional discharge of waste materials to surface waters during the proposed grade and fill activity. Pierre Grady Way Site SEPA Checklist 4/04/97 12 b. Groundwater: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description,purpose, and approximate quantities if known. The water table on the site is in contact with the bottom of the drainage channel through the site(4 to 6 feet below existing ground surface; American Engineering Corporation, April 1997a). Implementation of the proposal neither requires nor will result in withdrawal from or discharge to groundwater. The groundwater level will be approximately 10 feet below final grade following the proposed action. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any(for example: Domestic sewage; industrial, containing the following chemicals . . .; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s)are expected to serve. There will be no waste material discharged to the ground from septic tanks or other sources. c. Water Runoff(including stormwater): 1) Describe the source of runoff(including stormwater) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. Onsite drainage patterns indicate most existing stormwater runoff flows overland at various slopes less than 2 percent to the existing open drainage channel (American Engineering Corporation, April 1997b). There is no evidence of high flow or erosion within the channel, or at the point where drainage enters or exits the site in the channel. The remainder of the storm drainage system tributary to the site and downstream of the site, is described in Checklist Section B.3.a.1), above. No adverse downstream effects are projected to occur as a result of the proposed grading, filling, and drainage enclosure activities (American Engineering Corporation, April 1997b). This phase of the project will not increase surface water flows in the downstream system. No paved surfaces subject to vehicular traffic will be constructed on the site in conjunction with the proposed grading and filling activities. 2) Could waste materials enter ground or surface waters? If so,generally describe. There will be no intentional occurrence of waste materials reaching ground or surface waters. Pierre Grady Way Site SEPA Checklist 4/04/97 13 d. Proposed measures to reduce or control surface,ground,and runoff water impacts, if any: Best Management Practices(BMPs)for erosion/sedimentation control will be implemented during grading and filling activities. See Checklist.Section B.1.h, above. After grading and filling, the fill surface will be gently sloped and the site will be revegetated with grasses. All filter fabric fences will remain in place until site work features (rockeries, paving and landscaping) are installed under subsequent permit applications and approvals. Biofiltration will occur as a result of overland flow of stormwater runoff through grasses planted on the site following grade and fill activities. Interim drainage control measures during construction will include installing a filter fabric fence around the perimeter of work areas where fill is to be placed; protecting existing piped systems with filter fabric and/or placement of strawbales; placing rock or quarry spalls at construction entrances and exits; diverting water from the drainage channel (if necessary) during installation of CMPs and constructing adequate conveyance facilities for the interim condition; and grading the site to avoid ponding in areas where foundations, slabs or pavements are to be constructed. To the extent practicable, earthwork and enclosure of the existing drainage channel will be done during dry weather. All finished site elevations will be above+15 feet. Enclosing the drainage channel within corrugated metal pipes will reduce natural surface water infiltration, and thus minimize additions to the water table. The site-specific Stormwater Drainage Technical Information Report (American Engineering Corporation, April 1997b) contains an extensive appendix describing Operation and Maintenance BMPs for access roads and easements, closed detention systems, control structures and/or flow restrictors, catch basins, and conveyance systems (pipes and ditches). With the exception of underground conveyance facilities to be owned and maintained by the City of Renton, all onsite drainage facilities will be privately owned and maintained by the owner or site tenant. 4. PLANTS a. Check or underscore types of vegetation found on the site: deciduous tree: alder, maple, aspen,other: cottonwood,willow,ash _ evergreen tree: fir, cedar, pine, other shrubs: Scot's broom,Indian plum,elderberry _ grass _ pasture crop or grain _ wet soil plants: cattail,buttercup,bullrush,skunk cabbage,other _ water plants: water lily,eelgrass,milfoil,other other types of vegetation: invasive species—Himalayan blackberry,tansy Onsite vegetation, and the vegetative cover of offsite areas to the northwest, is generally characterized as an overgrown upland dominated by introduced species of woody vines mixed with Pierre Grady Way Site SEPA Checklist 4/04/97 14 some clumps of native trees and shrubs (John Comis Associates, September 1996). Himalayan blackberry dominates most of the site, mixed with a few other dominant plants in the area: big leaf maple, black cottonwood, red alder and some Oregon ash. Scot's broom, Indian plum and elderberry are found in some parts of the site's understory plant community. A few clumps of willow, hardhack (Spiraea) and buttercup occur along the drainage channel mixed with the dominant upland species in the non-wetland areas. No obligate wetland indicators were found on any part of the site (John Comis Associates, September 1996). b. What kind and amount of vegetation will be removed or altered? Three existing trees (8-inch minimum diameter) in the southwest corner of the site, vines and invasive plants will be removed during the proposed clearing, grading and fill operation. Exposed soils will be revegetated by hydroseeding or some other measure to minimize erosion by wind and rainfall. Landscaping will be introduced with the site development proposal. c. List threatened or endangered species known to be on or near the site. No threatened or endangered plant species are known to occur on or near the site. The site was specifically investigated for endangered,threatened or sensitive wetland plants(John Comis Associates, September 1996), and none were found. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: Landscaping to be installed with the site development proposal will be described in the Environmental Checklist on that action. 5. ANIMALS a. Underscore any birds and animals which have been observed on or near the site or are known to be on or near the site: Birds: hawk,heron,eagle,songbirds, other: Mammals: deer, bear,elk, beaver, other: Fish: bass, salmon,trout, herring,shellfish, other: Birds common in urban environments, such as starling, crow, robin and sparrow, likely inhabit and/or forage on the site at the present time. The site was not specifically examined for the presence of birds or animals. b. List any threatened or endangered species known to be on or near the site. No threatened or endangered animals species are known to utilize the site or urban project vicinity. Pierre Grady Way Site SEPA Checklist 4/04/97 15 c. Is the site part of a migration route? If so,explain. The Puget Sound area is part of the Pacific Flyway. Birds that inhabit the area vary seasonally due to migrations. There is no apparent unique or attractive attribute of the 2.74-acre site that would constitute a particular attraction to migratory birds. d. Proposed measures to preserve or enhance wildlife, if any: The applicant will comply with the U.S. Soil Conservation Service/City of Renton agreement to landscape at least 2 percent of the total site area for wildlife habitat. Landscaping for wildlife habitat will be aggregated on the site, and if possible, contiguous to wildlife habitat landscaping or open space on adjacent parcels to the north. Landscaping to be installed with the site development proposal will be described in the Environmental Checklist on that action. 6. ENERGY AND NATURAL RESOURCES a. What kinds of energy (electric, natural gas, oil, wood stove, solar) will be used to meet the completed project's energy needs? Describe whether it will be used for heating, manufacturing, etc. The energy requirements of the completed project will be discussed in the Environmental Checklist on the development proposal. Fossil fuels will be consumed by construction equipment involved in the clearing, grading and fill action. b. Would your project affect the potential use of solar energy by adjacent properties? If so, generally describe. Neither implementation of site grading and filling, nor the site development proposal would affect potential use of solar energy by adjacent properties. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: Obtaining a Grade and Fill Permit by early Summer 1997 will allow the applicant to take advantage of a nearby source of suitable fill material,thereby minimizing the consumption of fossil fuels to haul fill from a more distant source. Energy conservation features to be included in site development will be described in a separate Environmental Checklist on that action. Pierre Grady Way Site SEPA Checklist 4/04/97 16 7. ENVIRONMENTAL HEALTH a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. Phase I/Phase II Environmental Site Assessment has been performed on the Pierre Grady Way site to satisfy the level of review referred to as"due diligence by an innocent purchaser," according to the Superfund Amendment and Reauthorization Act of 1986 (SARA), and the Model Toxics Control Act (MTCA) of Washington State (Chapter 70.105D, Section 040 RCW). The consulting firm of Environmental Hazards Control was asked to assess the potential for contamination; the condition of visible hazardous materials or toxic substances; and to provide an understanding of any conditions that potentially constituted a health, safety or environmental hazard, or would diminish the value of the property. The following materials and conditions were evaluated during the site inspection: asbestos- containing materials, lead in paint,petroleum products, polychlorinated biphenyls, radon, storage tanks, hazardous materials, toxic substances, other unspecified hazards, and past or present contamination. A total of 23 samples were drawn from the 270-ft long abandoned railroad embankment and analyzed for heavy oil, diesel, PCBs, heavy metals and pH. None of the samples were found to contain hazardous substances above the MTCA Method A cleanup levels. Several samples contained coal slag and ash that were found to have low pH levels (acidic). No hazardous materials or toxic substance conditions defined by the U.S. Environmental Protection Agency (EPA) or Occupational Safety and Health Administration (OSHA) were found that required action (Environmental Hazards Control, September 1996). Several copies of this report have been submitted with this Environmental Checklist. A Puget Power representative was interviewed during preparation of the Environmental Site Assessment concerning the pad-mounted transformer along Oakesdale Avenue SW. Installed in 1988, this transformer is certified PCB-free by the manufacturer(Environmental Hazards Control, September 1996). There is a small risk of accidental spill and exposure to petroleum-derived fuels and lubricants associated with the temporary operation of earth moving equipment and other vehicles on the site during construction. 1) Describe special emergency services that might be required. There is no anticipated need for special emergency services associated with the proposed clearing, grading and fill operation on the site. 2) Proposed measures to reduce or control environmental health hazards, if any: Contract language could specify that earth moving equipment, when not in use, be parked in a prescribed area of the site as far away from drainage facilities as possible, and that fuel stored onsite (if any)be kept in a leakproof area(e.g., behind a designated berm or other suitable containment area) to intercept spills. Pierre Grady Way Site SEPA Checklist 4/04/97 17 Although acidic deposits of coal slag and ash found in the abandoned railroad embankment do not pose environmental health hazards, the consultant responsible for conducting the Phase I/Phase II Environmental Site Assessment suggests that it may be prudent to amend these deposits with lime if as a result of site grading, this material is to be used onsite (Environmental Hazards Control, September 1996). b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? The noise environment in the Pierre Grady Way site vicinity is dominated by vehicular traffic. The site is surrounded on two sides by arterial streets, and is less than one-quarter mile north of I-405 (see Figure 2). The site is also less than 2 miles from the Renton Airport, with the result that aircraft flyovers are a frequent source of noise. None of these noise sources will adversely affect the proposed grade and fill action. Neither are they projected to adversely affect the proposed automobile sales, service and/or rental use of the site. 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indicate what hours noise would come from the site. There will be a temporary increase in noise levels on the site associated with clearing, grubbing, and deposition of fill materials. These actions are projected to occur over a 2- to 3-week period. There will likely be an interim between earthwork and actual construction on the site, as a separate review and permitting process will be initiated for the land use decision, site work and building permits. Earthwork activities will be confined to the hours between 7:00 AM and 8:00 PM, in accordance with the City of Renton Mining, Excavation, and Grading Ordinance. Construction following grading and earthwork activities will be limited to the hours between 7:00 AM and 10:00 PM, in accordance with City of Renton and Washington State Noise Rules(WAC 173-60). 3) Proposed measures to reduce or control noise impacts, if any: Noise impacts associated with clearing, grading and filling the site are not projected to be significantly adverse in the setting in which the site is located. Therefore, no noise mitigation other than limiting the hours of earthwork and construction activity is proposed. Pierre Grady Way Site SEPA Checklist 4/04/97 18 8. LAND AND SHORELINE USE a. What is the current use of the site and adjacent properties? The site is presently vacant except for the presence of electrical transmission lines. High voltage power lines pass through the property in an east-west direction, approximately bisecting Parcels B and D(see Figure 3). Jumper lines that convey power for local usage extend north and south from the high voltage lines across the west end of Parcel B. The metal towers, plinths, wood utility poles, guy wires and guy wire anchors are fixed features. Existing easements for electrical transmission lines affect Parcels A through F. There are two additional physical features of significance on the site: a large open drainage channel, and a former railroad embankment. The drainage channel is approximately 4 to 6 feet deep, and parallels the north boundary of Parcel B. Puget Western, Inc. (former property owner) and the City of Renton entered into an easement agreement in May 1985 for this drainage channel across the site. The channel and the corrugated metal pipe (CMP) culverts of the outlet (48-inch and 72-inch diameter), substantially consume Parcel C at the west end of the site. The easement agreement includes a provision that allows Puget Western and successors to develop and use the land encumbered by the easement. The remnant segment of a former railroad embankment on the site rises 10 to 14 feet above the elevation of the remainder of Parcel A, substantially occupying this parcel (see Figures 1 and 3). Adjacent property land uses include City of Renton arterial streets(SW Grady Way and Oakesdale Avenue SW) south and west of the site; and three-story office buildings to the north and northeast. Property immediately north of and adjacent to the site is vacant. Property west of the site (west of Oakesdale Avenue SW) is a small tract of public open space south of the Metro Renton sewage treatment plant. b. Has the site been used for agriculture? If so, describe. Historical aerial photographs (1935 to 1995) were reviewed in conjunction with the Phase I and Phase II Environmental Assessment of the site (Environmental Hazards Control, September 1996). Throughout this 59-year photographic record, the site appears similar to present conditions: undeveloped and covered with thick vegetation. The drainage ditch and high voltage transmission lines were present during this period. A single railroad track crossed the northern parcel, originally developed prior to the 1930s and removed during the late 1970s and early 1980s. Therefore, during the known history of this site, it has not been used for agriculture c. Describe any structures on the site. There are no "structures" on the site, per se. There are high voltage electrical transmission lines, as described in Checklist Section B.8.a, above. Historical aerial photographs for the period 1935 to 1995 reveal that there has never been a major structure on this site (Environmental Hazards Control, September 1996).

The site is currently zoned Commercial Office(CO). f. What is the current comprehensive plan designation of the site? The current City of Renton Comprehensive Plan designation of the site is Employment Area— Valley(EAV). g. If applicable,what is the current shoreline master program designation of the site? The site is not within a 200-ft shoreline environment. h. Has any part of the site been classified as an "environmentally sensitive" area? If so, specify. The site is not within a City of Renton environmentally sensitive area. i. Approximately how many people would reside or work in the completed project? There will be no resident population on the site, nor permanent employment associated with the proposed grade and fill action. Employment associated with the proposed automobile sales, service and/or rental use will be estimated at the time a separate Environmental Checklist is prepared for that proposed action. j. Approximately how many people would the completed project displace? The project will displace no residents or workers. k. Proposed measures to avoid or reduce displacement impacts, if any: No mitigation measures are proposed for displacement impacts, since there will be none. 1. Proposed measures to ensure the proposal is compatible with existing and projected land uses and plans, if any: The proposed grade and fill action constitutes the first phase of plans to develop the Pierre Grady Way site for automobile sales, service and/or rental uses. A City of Renton Long Range Planning Division memorandum (February 11, 1997)issued in response to the project preapplication (File #97- 12) indicates that the proposed use falls within the range of uses intended for the City of Renton Comprehensive Plan Employment Area—Valley (EAV) designation. The EAV designation provides Pierre Grady Way Site SEPA Checklist 4/04/97 21 for a mixture of commercial, office and industrial uses. The location and design of site development to achieve compatibility with adjacent uses will be discussed in a separate Environmental Checklist to be prepared for the consolidated Rezone and Site Plan Approval application. 9. HOUSING a. Approximately how many units would be provided, if any? Indicate whether high, middle, or low-income housing. No housing units will be provided on the site. b. Approximately how many units, if any, would be eliminated? Indicate whether high, middle, or low-income housing. No housing units will be eliminated. c. Proposed measures to reduce or control housing impacts, if any: No mitigation measures are proposed for housing impacts, since there will be none. 10. AESTHETICS a. What is the tallest height of any proposed structure(s), not including antennas; what is the principal exterior building material(s) proposed? The proposed grade and fill operation does not involve building any structures on the site. A separate, consolidated Rezone and Site Plan Approval application will be filed to describe the development proposal for the site. An Environmental Checklist specific to the development proposal will be prepared to accompany the Rezone/Site Plan Approval application. b. What views in the immediate vicinity would be altered or obstructed? No views in the immediate vicinity will be altered by the proposed grade and fill operation. All finished site elevations will be above +15 feet, designed to match or lie slightly below the elevation of adjoining arterial streets. c. Proposed measures to reduce or control aesthetic impacts, if any: No mitigation measures are proposed for aesthetic impacts, since none are projected to occur. Pierre Grady Way Site SEPA Checklist 4/04/97 22 11. LIGHT AND GLARE a. What type of light or glare will the proposal produce? What time of day would it mainly occur? The short-term(2-to 3-week)grade and fill operation is not expected to have any associated light or glare impacts. b. Could light or glare from the finished project be a safety hazard or interfere with views? Since no light or glare impacts are projected to occur with the proposed grade and fill operation, there will be no safety hazards nor view interference as a result. c. What existing offsite sources of light or glare may affect your proposal? Existing offsite sources of light and glare include street lights, passing vehicles during non-daylight hours, and general light levels associated with the close proximity of the site to downtown Renton. None of these sources is projected to adversely affect the proposed grade and fill action. d. Proposed measures to reduce or control light and glare impacts, if any: No measures are proposed to reduce or control light and glare impacts associated with the proposed grade and fill operation, since none are projected to occur. 12. RECREATION a. What designated and informal recreational opportunities are in the immediate vicinity? There is a small passive open space area south of the Metro Renton treatment plant, west of Oakesdale Avenue SW—opposite the site. The City of Renton Comprehensive Plan (August 12, 1996) indicates a system of existing and proposed bicycle and pedestrian facilities surrounding the site, on SW 7th Street; Powell Avenue SW/SW 16th Street;Monster Road; Oakesdale Avenue SW; and the proposed Springbrook Wetlands Trail. b. Would the proposed project displace any existing recreational uses? If so, describe. Implementation of the proposed grade and fill operation will not displace any existing or planned recreational uses. Pierre Grady Way Site SEPA Checklist 4/04/97 23 . c. Proposed measures to reduce or control impacts on recreation, including recreation opportunities to be provided by the project or applicant,if any: No measures are proposed to reduce or control impacts to recreation, as no impacts to designated or informal recreational opportunities are anticipated as a result of the proposed grade and fill action. 13. HISTORIC AND CULTURAL PRESERVATION a. Are there any places or objects listed on, or proposed for, national, state, or local preservation registers known to be on or next to the site? If so,generally describe. There are no known places or objects on the site or in the site vicinity that are listed on, or proposed for, national, state, or local preservation registers. b. Generally describe any landmarks or evidence of historic, archaeological, scientific, or cultural importance known to be on or next to the site. There are no known landmarks or evidence of historic, archaeological, scientific or cultural importance on or near the site. c. Proposed measures to reduce or control impacts,if any: No measures are proposed to reduce or control impacts to historic or cultural resources, as no impacts to resources of this nature are anticipated. 14. TRANSPORTATION a. Identify public streets and highways serving the site, and describe proposed access to the existing street system. Show on site plans, if any. The Pierre Grady Way site is bordered on three sides by public streets: Powell Avenue SW on the east, SW Grady Way on the south, and Oakesdale Avenue SW on the west(see Figure 1). SW Grady Way is a City of Renton major arterial, and a designated truck route. SW Grady Way and Oakesdale Avenue SW are each four lanes wide with left-turn pockets in the site vicinity. The intersection of Oakesdale Avenue SW with SW Grady Way is signalized. The site has excellent access via SW Grady Way to I-405 and SR-167. Access to the existing street system is proposed from three driveways: two to be constructed along the south boundary of the site for access to/from SW Grady Way, and one to be constructed along the west boundary for access to/from Oakesdale Avenue SW(see Figure 1). Pierre Grady Way Site SEPA Checklist 4/04/97 24 b. Is site currently served by public transit? If not, what is the approximate distance to the nearest transit stop? Several Metro Transit routes operate in the project vicinity via SW Grady Way. The route nearest the site is Route 153, operating between Kent and Renton via E. Valley Road, Lind Avenue SW, SW 16th Street and Oakesdale Avenue SW to S. Grady Way. Route 153 provides service from Enumclaw through Auburn,Kent,Renton, Southcenter and Tukwila to downtown Seattle. The South Renton Transit Center is located at the intersection of S. Grady Way and Shattuck Avenue S, approximately one mile east of the Pierre Grady Way site. Connections to numerous other routes serving residential areas, employment centers, and city centers are available at this facility, and at the Downtown Renton Transit Center on Burnett Avenue S. between S. 2nd and S. 3rd Streets (approximately 2.5 miles northeast of the site). c. How many parking spaces would the completed project have? How many would the project eliminate? Phase 1 clearing, grading and filling will neither eliminate nor add parking spaces to the site. The number of parking spaces to be provided in the .completed project will be discussed in the Environmental Checklist on the development proposal. d. Will the proposal require any new roads or streets, or improvements to existing roads or streets, not including driveways? If so, generally describe(indicate whether public or private). Neither the proposed grade and fill action, nor ultimate development of the Pierre Grady Way site will require new roads or streets, or improvements to existing roads and streets. Three new points of driveway access are proposed with the automobile sales, service and/or rental use of the site: two from SW Grady Way, and one from Oakesdale Avenue SW(see Figure 1). e. Will the project use (or occur in the immediate vicinity of) water, rail, or air transportation? If so,generally describe. The project will not use or occur in the vicinity of water, rail or air transportation in a manner that will result in significant interaction between project traffic and these modes of travel. The northern parcel of the site was originally developed by Puget Sound Electric Railway prior to the 1930s, crossed by a single track used until the late 1970s or early 1980s. Use of this track was discontinued to accommodate commercial development by others along SW Grady Way (Environmental Hazards Control, September 1996). Due to the former railroad use of this parcel, a Phase I/Phase II Environmental Site Assessment was conducted to determine whether there had been possible soil contamination associated with past railroad activity. No contamination was found. (See discussion in the Environmental Health section, Checklist Section B.7, above.) Pierre Grady Way Site SEPA Checklist 4/04/97 25 f. How many vehicular trips per day would be generated by the completed project? If known,indicate when peak volumes would occur. It is estimated that approximately 670 to 820 truck trips will occur during the proposed site clearing, grading and filling operation (Phase 1), depending on the type of truck and trailer combinations used. It is projected that these trips will occur over a 2- to 3-week period. Therefore, the estimated number of truck trips per day(assuming 5 days per week of operation) is about 45 to 82 trips. There is no particular period of the day when peak truck trip volumes would occur during the clearing, grading and filling phase. The preferred source of fill will be available between June and August 1997 from construction at the Metro Renton sewage treatment plant site, approximately one- half mile northwest of the Pierre Grady Way site on Oakesdale Avenue SW. Driveway access to the site will be provided directly from Oakesdale Avenue SW. Trucks operating only on Oakesdale Avenue SW between the site and the Metro Renton treatment plant will not be restricted to offpeak operational hours, due to comparatively low traffic volumes on Oakesdale Avenue SW. Haul routes for approximately 2,000 cu yd of debris to be removed from the site, and for special purpose fill materials (e.g., pipe bedding gravel) will be selected by the contractor. These truck trips are likely to use SW Grady Way east of the site, and SR 167 south of Renton. g. Proposed measures to reduce or control transportation impacts, if any: Heavy truck trips operating on routes east, west and/or south of the Pierre Grady Way site will be restricted to offpeak non-project traffic hours,between the hours of 8:30 AM and 3:30 PM. 15. PUBLIC SERVICES a. Would the project result in an increased need for public services (for example: fire protection,police protection, health care,schools, other)? If so,generally describe. The proposed clearing, grading and filling action will result in no .increased need for public services. b. Proposed measures to reduce or control direct impacts on public services, if any. Since no impacts to public services are projected, no mitigation is proposed. Pierre Grady Way Site SEPA Checklist 4/04/97 26 16. UTILITIES a. Underscore utilities currently available at the site: electricity, natural gas, water, refuse service, telephone,sanitary sewer,septic system,other: storm drainage. The underscored utilities are available to the Pierre Grady Way site from the following providers: Puget Sound Energy Systems Electricity City of Renton Water City of Renton Sanitary sewer City of Renton Storm drainage U.S. West Communications Telephone Rainier Waste Management Commercial solid waste collection service b. Describe the utilities that are proposed for the project, the utility providing the service, and the general construction activities on the site or in the immediate vicinity which might be needed. It is a component of the proposed grade and fill action to install a subsurface storm drainage conveyance system in the existing open conveyance channel through the site. The existing drainage channel is significantly oversized for the amount of runoff it conveys; however, the subsurface system to be installed will be sized to match its conveyance capability. The City of Renton has maintenance responsibility for this facility by means of an easement agreement. Construction activities required to create the subsurface stormwater conveyance system are described in Checklist Sections A.11 and B.3, and illustrated in the set of drawings submitted with this application. Application is not being made at this time for construction of water, sewer, electrical or communications systems. These utilities will be elements of the site development proposal, to be addressed in a separate application and Environmental Checklist. C.

We initiated the development review process in January 1997, with submittal of a request for Preliminary Project Review (City of Renton File #97-12). The Preliminary Project Review meeting was held February 13, 1997. A source of fill is available to Mr. Pierre during Summer 1997, possibly before a consolidated Rezone and Site Plan Approval process could be completed. Therefore, we are applying separately in advance for a Grade and Fill Permit to be in a position to receive the preferred source of fill. The consolidated Rezone and Site Plan Approval application will follow in a matter of weeks. All Grade and Fill Permit submittal requirements are enclosed in the quantities specified in City of Renton Development Services Division procedures. The following explanation is offered with regard to some of these submittal requirements. • Certification of Current Property Ownership is on the back side of the List of Surrounding Property Owners sheet. • Mr. Pierre has enclosed a check for $3,000, which is our understanding of the amount due to process the Grade and Fill Permit application ($2,000) and conduct environmental review ($1,000). • The Project Narrative has been included on the plan sheets. • A Tree Cutting/Land Clearing Plan was waived for this site by Mr. Jim Chandler, Building Official, during the Preapplication meeting Feburary 13, 1997 (copy of waiver attached). 7732 18TH AVENUE NORTHEAST • SEATTLE,WA 98115-4426 - FAX: (206) 523-4648 - PHONE: (206) 522-8057 City of Renton Development Services Re: Pierre Grady Way Site (File #97-12) April 7, 1997 • Instructions for the Construction Mitigation Plan contain the same elements as the Project Narrative. Therefore, this information is provided on the plan sheets under the heading: Project Narrative. Additional mitigation measures for the proposed grade and fill action are described in the Environmental Checklist. Please call if you require any additional items or information for Grade and Fill Permit application review.

Also, the property was crossed (overhead)by Puget Sound Power and Light Company high tension electrical lines. See: MAPS AND DRAWINGS and SCHEDULE OF PHOTOGRAPHS. According to available data, institutional knowledge and historical aerial photographs dating back to 1936, the subject property had not had a major structure constructed on site. A portion of the site was originally developed by Puget Sound Electric Railway prior to the 1930's and used for railroad purposes up to the 1970's. The railroad track and ties were removed in the late 1970's and early 1980's to accommodate future commercial development along SW Grady Way. No other use of the site was discovered during the survey. See: PROPERTY DESCRIPTION, PROPERTY REPORTS and HISTORICAL AERIAL PHOTOGRAPHS. The Phase I conducted by Environmental Hazards Control, Federal Way, Washington in September 1996 revealed a moderate to high potential for hazardous materials or toxic substances. Based on the historical use of the site(railroad and undeveloped), EHC drew a series of surface and subsurface soil samples for possible contamination related to railroad activity as part of the Phase II. A total of 23 samples were drawn from the approximately 270 foot long abandoned railroad bed and analyzed for heavy oil, diesel, PCBs, heavy metals and pH. None of the samples were found to contain hazardous substances above the MTCA Method A cleanup levels. Several of the samples (coal slag and ashes)were found to have low pH levels (acidic). The material may require some amendment (lime)to balance the pH level if used on-site. See: RECOMMENDATIONS and LABORATORY ANALYSIS. No surface staining, dead or dying vegetation or related conditions were viewed on or near the properties during this review. Although, some waste concrete and asphalt had been dumped on the Northeast corner of the property. The properties adjacent to the sites consisted of undeveloped land or commercial office buildings surrounded by asphalt parking. EHC discovered some waste concrete and asphalt on the adjacent property to the Northwest of the subject property. And, a solid and liquid waste rendering plant (METRO)was located Northwest of the subject property. No industrial or manufacturing facilities were located adjacent to the properties. See: RECOMMENDATIONS. A total of 16 sites were found in the data bases reviewed for generators, storers or transporters of 1 y Project #: PIERRE996 hazardous wastes, underground storage tanks or leaking underground storage tanks within a 1 mile radius of the subject properties. See: DATA BASES REVIEW. None of the personnel interviewed as part of this survey reported any past or current conditions that would indicate a concern or warrant further investigation. See: INSTITUTIONAL KNOWLEDGE. And, no hazardous materials or toxic substances conditions defined by the U.S. Environmental Protection Agency or Occupational Safety and Health Administration were found that required action. 2 Project #: PIERRE996 2.0 CERTIFICATION AND LIMITATIONS • Environmental Hazards Control (EHC)is providing data, information and recommendations for the express purpose of the Client.

Property Reports . 5 I Project #: PIERRE996 3.0 PURPOSE The purpose of this survey was to satisfy the level of review referred as "due diligence" by an "innocent purchaser" in the Superfund Amendment and Reauthorization Act of 1986 (SARA), and the Model Toxics Control Act (MTCA) of Washington State, Chapter 70.105 D (Section 040)RCW as it applies to the standards of liability and environmental reviews of property. Also, Environmental Hazards Control (EHC) was asked to assess the potential for contamination,the condition of visible hazardous materials or toxic substances and to provide an understanding of any conditions that were a health, safety or environmental hazard or would diminish the value of the property. The following are those materials or conditions that were evaluated during the inspection(s); ► Asbestos-Containing Materials ► Lead in Paint ► Petroleum Products ► Polychlorinated Biphenyls • ► Radon ► Storage Tanks ► Hazardous Materials Toxic Substances ► Other Hazards;Unspecified ► Contamination;Past or Present EHC was contacted to perform a Phase I on the subject properties by Donald A. Moody of Western Pacific Properties, Inc. for Pierre Enterprises, Inc. (Client). Mr. Moody discussed with Steven J. Salter of EHC the current and past uses of the site and general conditions on the premises prior to starting the physical inspection and general investigation. Also, he provided real estate listings that provided a description of the properties. The investigations was to determine any risks and offer recommendations on further investigation; if warranted. Approximately 2 weeks into the investigation, it became apparent that a subsurface investigation was warranted due to the site conditions and historical use of the site. So, EHC was directed by Western Pacific Properties, Inc. to conduct a Phase II -Environmental Assessment (Phase II) in conjunction with the Phase I. The results of the initial investigation and follow-up surface and subsurface investigation are presented in this report. 4.0 PROPERTY DESCRIPTION The subject properties inspected for this Phase I and Phase II were located in the Southeast corner of the city of Renton, Washington. The properties were being sold as one contiguous piece of land and therefor were investigated and described in this report as a single piece of 6 Project #: PIERRE996 property. A general description of the site has been provided below and the legal description for the individual pieces of land may be found in PROPERTY REPORTS: Parcels A, B, C, D, E and F(Apx: 119,500 square feet) The irregular shaped property was located between Oaksdale Avenue SW and Powell Avenue SW along the North side of SW Grady Way, Renton, Washington. The site was originally semi-level, appeared to slope to the Northwest and was covered with thick blackberry. But, the site had a deep (7 to 10 feet) drainage ditch that ran parallel to the elevated (10 to 15 feet)abandoned railroad track (South side). EHC viewed running water in the ditch during the site investigations. See: MAPS AND DRAWINGS and SCHEDULE OF PHOTOGRAPHS. 5.0 INVESTIGATION AND FINDINGS The site surveys were conducted by Mr. Salter on September 10, 12, 19 and 20, 1996 based upon proposals to the Client. The site surveys consisted of a physical inspection of the subject properties and surface and subsurface soils testing. 5.1 TOPOGRAPHICAL AND GEOLOGICAL CONDITIONS No borings or test pits were dug in native soils to characterize soil stratigraphy during this survey. Alth , uf inti the "Black Riverough" deltasr ace of partiallysoilsand saturated as peat nto andsite clay.soils were Accorcodingsis to ent thew"Wth aterthe soil Resources of of King County, Washington", Geological Survey Water-Supply Paper 1852, the properties were located in what is commonly referred as the "Puget Sound Lowlands". The area has undergone glaciation numerous times resulting in sedimentation of unconsolidated rock that is a thousand feet thick in parts of King County. See: MAPS AND DRAWINGS. As part of the Phase II,test pits were advanced to a depth of approximately 15 feet bgs through the railroad right-of-way bed. A general description of the soils has been provided below: • 0 to 3' 1" -3" rock/railroad ballast • 3'to 11' -14' Coal slag, ash and ballast • 11'to 15' Clay sands See: TEST PIT LOGS Groundwater data for the specific area was unavailable at the time of this survey. Although, perched water is known to flow towards the Northwest throughout the general area and is usually found between 4 to 15 feet bgs. See: REFERENCES and MAPS AND DRAWINGS. 7 Project #: PIERRE996 5.2 ASBESTOS-CONTAINING MATERIALS Asbestos has been used in numerous building materials since the late 1900's and up until the early to mid-1980's. The quote, "Asbestos is where you find it...", neatly describes the use of asbestos in almost every type of building product. A material is considered to be an asbestos-containing material (ACM) if the concentration of asbestos in a core bulk sample, or single distinct layer of a sample, is found at a concentration greater than one percent (1%)based on a weight/weight basis. No suspect ACMs were found at the subject properties. 5.3 LEAD IN PAINT The use of lead-based paints (LBP)was common throughout the United States. To reduce the risk of inhaling or ingesting of cracking, scaling, chipping, chaulking or peeling LBP the United States, Environmental Protection Agency(USEPA)has developed procedures for the detection, removal and disposal of the material. Painted surfaces that contain 1 mg/cm2 (microgram per centimeter squared) are considered to contain lead when analyzed using an X-ray fluorescence analyzer. A bulk paint sample that contains lead in concentrations of 5000 ppm(part per million) is considered lead-containing when analyzed by an analytical method called atomic absorption (AA). No suspect LBP were found at the subject properties. 5.4 PETROLEUM PRODUCTS No stored or containerized petroleum products were viewed at either site during this initial survey. Note: Surface and subsurface sampling for petroleum contamination was conducted by EHC during this survey along the railroad right-of-way only. See: PHASE II -ENVIRONMENTAL ASSESSMENT. 5.5 POLYCHLORINATED BIPHENYLS A variety of transformer oils or mineral oils containing polychlorinated biphenyls (PCB)have been used in the past in electrical transformers, switches and light ballasts. A variety of sizes are often found in basements, utility tunnels, electrical utility rooms, on telephone poles in "stepdown" electrical transformers or in fluorescent light ballasts in occupied spaces. The current USEPA standard for PCB-contaminated fluid in electrical equipment is 50 ppm of PCB in oil. Equipment found to contain greater than 500 ppm of PCB are considered PCB-containing. Fluorescent light 8 J 1 ' Project #: PIERRE996 ballasts manufactured prior to 1979 are known to often contain PCB. Dana Crawford of Puget Sound Power and Light Company reported over the telephone on September 23, 1996 the pad mounted transformer along Oaksdale Avenue Southwest was installed in 1988 and certified PCB free from the manufacturer. See: RFI LETTERS AND RECORDS REVIEW. Note: Surface and near surface sampling for PCB contamination was conducted by EHC during this survey along the railroad right-of-way only. 5.6 RADON Radon (Rn 222)is a radioactive gas that is emitted from the decay of naturally occurring radioactive Uranium (U-238)which is abundant in the soil throughout the US. Since it is gaseous, it will follow voids, fissures, or holes in the floor of basements and accumulate if ventilation is poor. Based on studies conducted by the Bonniville Power Administration (BPA), radon levels in the greater Seattle area inside buildings are most often a fraction of the recommended allowable exposure level. Also, given the soil type listed for the area, high concentrations of radon would not be typical. No structures were on the sites and given the types of soils present throughout the valley,EHC believed the potential for elevated concentrations of radon was low. 5.7 STORAGE TANKS No aboveground storage tanks (AST) or underground storage tanks (UST)were located on the subject properties. No fill pipes or vent piping were viewed during this initial survey. 5.8 HAZARDOUS MATERIALS AND TOXIC SUBSTANCES Typically, hazardous materials and toxic substances are found in industrial chemicals such as solvents, auto chemicals, cleaning agents, paints and related chemical used at various facilities for production, maintenance and repair activities. An examination of the sites for containerized hazardous materials was made and none were found. Note: Surface and subsurface sampling for hazardous materials and toxic substances contamination was conducted by EHC during this survey along the railroad right-of-way only. See: PHASE II -ENVIRONMENTAL ASSESSMENT. 9 . l r Project #: PIERRE996 5.9 OTHER HAZARDS; UNSPECIFIED During the site inspection, observations were made for conditions, chemicals, materials or a combinations that would present a hazard or risk to the persons at the site. No additional conditions of significance were found at either site. 5.10 CONTAMINATION; PAST OR PRESENT Based on the historical use of the properties (railroad and undeveloped land), there was a low to moderate potential for petroleum and heavy metals contamination in the railroad right-of-way. No hazardous substances were found that exceeded the MTCA Method A cleanup level. See: PHASE II -ENVIRONMENTAL ASSESSMENT. 6.0 INSTITUTIONAL KNOWLEDGE As part of the Phase I, EHC interviewed personnel related with the project The following is a listing of those persons interviewed for this survey: Donald A. Moody of Western Pacific Properties, Inc. provided the following information: Pierre Enterprises, Inc. (James P. Pierre) needs to understand if there are any environmental concerns with the property prior to purchase. The properties are being sold off by Puget Western, Inc. The work must be completed by the end of September due to pending sales. The properties have never been developed and therefor we do not think you will find any problems with the sites. Although, a railroad once crossed the site. James P. Pierre of Pierre Enterprises, Inc. provided the following information: We intend to improve the site and possibly build a car lot on it. I need to know if their are any environmental concerns". Dana Crawford of Puget Sound Power and Light Company provided the following information: "The pad mounted transformer along Oaksdale Avenue Southwest was installed in 1988.and certified PCB free by the manufacturer". 7.0 ADJACENT PROPERTIES AND OUTSIDE CONDITIONS During the site inspection, observations were made for conditions on adjacent properties or in the area that would present a hazard or risk to the subject property. The property was located in an area that had historically been dominated by undeveloped land and agriculture. There was no 10 e a t 1 Project #: PIERRE996 industrial/manufacturing activity adjacent to the site. See: MAPS AND DRAWINGS and DATA BASES REVIEW. The properties listed below were located adjacent to the subject property at the time of this initial survey: N: Undeveloped property and multi-story office buildings surrounded by asphalt parking NE: Multi-story office buildings surrounded by asphalt parking E: Powell Avenue Southwest and undeveloped land SE: SW Grady Way, I405 and multi-story office buildings S: SW Grady Way, I405 and multi-story office buildings SW: SW Grady Way, I40S and multi-story office buildings W: Oaksdale Avenue Southwest and a graded lot NW: METRO; solid and liquid rendering plant After a complete review of available data bases, physical inspections around the subject properties and driving the road system around the area, EHC believed the potential for off-site contamination was low. EHC based its decision on the DATA BASES REVIEW, adjacent property activity(undeveloped land and residential) and the topography in the subject area. 8.0 DATA BASES AND AGENCY RECORDS In order to satisfy the level of review referred as "due diligence" by an "innocent purchaser" in the SARA as it applies to standards of liability, a review of pertinent data bases was conducted. In accordance with the Phase I, EHC contracted VISTA Information Solutions, Inc. (VISTA)to conduct a data bases review within 1 mile of the subject property. EHC contacted local regulatory agencies with jurisdiction for records on the site. There were a total of 16 mapped and unmapped site listed as an independent cleanup sites, UST or LUST sites or incident sites within l mile of the subject property. There were a total of 7 sites mapped and unmapped and listed as an independent cleanup sites, UST or LUST sites or incident sites within 1/4 mile of the subject property. See: DATA BASES REVIEW and RFI LETTERS AND RECORDS REVIEW.

Based on the initial data collected in the Phase I, an abandoned railroad line bed had been located on the North side of the property: Potential sources of contamination around the abandoned railroad bed were petroleum hydrocarbons(diesel and oil), heavy metals and high ph levels. The site, easements and abandoned improvements are shown on the enclosed engineering drawings from American Engineering Corporation: ► Establish baseline soil conditions; ► Ascertain the nature and extent of petroleum hydrocarbon and heavy metals related contamination, if present, in site soils on and in the railroad right-of-way. 9.2 SERVICES The following services were provided by EHC: ► Reviewed Phase I data and developed a surface sampling plan; ► Drew 14 surface and near surface soil samples along the 270 foot length of abandoned railroad bed petroleum hydrocarbons; ► Reviewed TLC analysis of surface and near surface soil samples; ► Developed subsurface sampling plan; ► Provided field supervision during the subsurface investigation; ► Advanced 4 test pits and logged soil stratigraphy; ► Submitted a total of 9 soil samples for chemical analysis using the following methods: 1. Washington State Method WTPH-D,Extended for diesel and oil in soil 2. EPA Method 6010 for total metals in soil 3. EPA Method 7471 for mercury in soil 4. EPA Method 9045 for pH in soil 13 i Project #: PIERRE996 Summarized the data in a report with attachments. 9.3 FIELD INVESTIGATION A total of 14 surface and near surface soil samples were drawn from the approximately 270 foot long by 16 foot wide by 14 foot high abandoned railroad right-of-way (bed). The samples were drawn at locations that would best profile the area (under and around tracks and ties)for surface contamination and assist in determining the best locations for subsurface testing (test pits). The samples were collected by EHC on the morning of September 19, 1996 and analyzed at Nowicki & Associates, Federal Way, Washington the morning of September 20, 1996. The samples were analyzed by the field screening methodology thin layer chromatography (TLC)for the presence of oil and PCBs. It was reported that no oil or PCBs were detected in any of the samples analyzed. (TLC-1 to TLC-14). See: LABORATORY ANALYSIS.. Given the TLC analysis of surface soils, EHC excavated 4 test pits(TPW20, TPW100, TPW 180 and TPW260) on the morning of September 20, 1996. Test pits TPW20 and TPW260 were excavated to a depth of about 15 feet bgs and 13 feet bgs;respectively. Test pits TPW100 and TPW 180 were excavated to a depth of about 6.5 feet each. Soils generally consisted of about 3 feet of ballast (1 inch to 3 inch rock) and 8 to 11 feet of coal slag and ash mixed with ballast. See: TEST PIT LOGS. Soils were examined for type and then samples were collected using a clean stainless steel trowel. Samples were contained within 4 ounce and 8 ounce laboratory cleaned jars with teflon lined lids. All samples were stored in a cooler, with freezer packs, during field operations and while in transit or storage. Sampling tools and equipment were cleaned using trisodium phosphate, water and a distilled water wash before and between drawing samples. All test pits were backfilled and compacted with the Hitachi EX-60 trackhoe. 9.4 ANALYTICAL RESULTS The subsurface soil samples were delivered to SPECTRA Laboratories, Inc. (SPECTRA)in Tacoma, Washington for analysis on the afternoon of September 20, 1996. The samples were analyzed following the methods outlined above on a "rush" basis. See: 9.2 SERVICES. EHC received analytical results by facsimile late on the morning of September 25, 1996. None of the samples analyzed were found to contain hazardous substances above the MTCA Method A, cleanup levels. Although, the pH level in the:coal slag and ash samples(TPW20-2, TPW20-3, TPW100-2, TPW 180-2 and TPW260-2 were on the low side(acidic). The typical pH range found in western Washington is between 4.5 to 6 on the pH scale. The analytical results are summarized in Table 15-1 and copies of the.apalytical reports have been attached. See: LABORATORY ANALYSES. 14 s Project #: PIERRE996 Table 15-1 • Summary of Chemical Analyses in Soil Abandoned Railroad Right-of-Way Sample Sample Depth Oil Diesel Total pH Number Date bgs mg/Kg mg/Kg Metals TPW20-1 09/20/96 1' <100 <25 NA NA • TPW20-2 09/20/96 5' <100 <25 BA 4.01 TPW20-3 09/20/96 5' <100 <25 BA 3.76 TPW100-1 09/20/96 1' <100 <25 NA NA TPW100-2 09/20/96 5' <100 <25 BA 4.61 TPW180-1 09/20/96 5" <100 <25 NA NA TPW 180-2 09/20/96 5.5' <100 35 BA 4.70 TPW260-1 09/20/960 1.5' <100 <25 BA NA TPW260-2 09/20/96 5' <100 <25 BA 4.85 All values reported in milligrams per kilogram (mg/Kg).

See: PROPERTY REPORTS. The report chronicled the ownership of the individual properties dating back to 1930. Generally, the properties were held for a railroad right-of-way, electrical utilities and individual and corporate investment purposes. See: PROPERTY REPORTS. • • 15 • Project #: PIERRE996 11.0 SUMMARY AND CONCLUSIONS 1. The majority of the parcels had not been developed but, a railroad right-of-way and high tension electrical lines crossed the site (East to West) 2. A surface and subsurface investigation of the railroad right-of-way was conducted and no hazardous substances were found above the MTCA Method A cleanup levels. 3. Waste concrete and asphalt had been dumped on the Northeast corner of the site. See: MAPS AND DRAWINGS. 4. No physical conditions were found on site that warranted additional investigation. But, as with any property, it is always possible that areas with undetected contamination may exist in portions of the site where no subsurface exploration was performed. 12.0 RECOMMENDATIONS Based on available information, site conditions viewed and adjacent site activities, the following recommendation are made: 1. It may be prudent to add a soil amendment (lime)to the coal slag and ash if the railroad right-of-way is graded level and the material is used on-site. 2. Dispose of the waste concrete and asphalt at an approved recycling center for the materials. 2. No other conditions were found on-site that warranted a concern. Note: Surface and/or subsurface sampling for contaminants was conducted by EHC during this initial survey in the railroad right-of-way only. • 16 i i r Project #: PIERRE996 13.0 REFERENCES • 1.

Operation and Maintenance BMPS 2 1.0 Project Overview Mr. Jamie Pierre owns the subject site which is located at the NE corner of the intersection of SW Grady Way and Oakesdale Avenue SW in the City of Renton, Washington. (See Figure 1: "Vicinity Map".) Mr. Pierre is in the process of applying for permission to develop the 2.74 acre subject site for use as a rental car regional facility or an automobile sales dealership. See City of Renton Pre-Application File #97-12. A Pre-Application meeting was conducted at the City of Renton on February 13, 1997. The existing zoning is Commercial Office (CO). Mr. Pierre intends to apply for a rezone to Medium Industrial (IM) to permit the proposed use. The proposed rezone and Site Plan Approval process will likely occur over the next 4 to 6 months. As a separate matter, whether rezone is allowed or not, Mr. Pierre seeks permission to fill and grade the site. Filling of the site is allowed under either the existing CO or requested IM zoning, and as defined in the existing drainage easement in favor of the City of Renton. (See Appendix A, Item #3 of drainage easement.) The site is currently 3 to 5 feet below the surrounding street elevations. The north parcel contains a former railroad grade at an elevation slightly higher than the adjacent parcels. An existing 740 foot long grass lined drainage channel located along the north lines of Parcels B and C conveys stormwater runoff from east to west. (See Appendix A, Record of Survey.) In order to provide feasible use of the site under CO or IM land use parameters, the site must be filled and a piped stormwater drainage system constructed to replace the existing open drainage channel. It is Mr. Pierre's intent to obtain permission from the City of Renton to fill the site and commence with fill placement during June 1997. This report contains information defining the stormwater system components required to be constructed i for both enclosure of the existing channel and proposed developed site conditions. This report is in conformance with the drainage requirements of the City of Renton Department of Public Works, Utility Systems, Surface Water Section. The City of Renton requirements for stormwater system design are a modified version of the 1990 King County Department of Public Works Surface Water Design Manual. ' , 2.0 Preliminary Conditions Summary The subject site consists of six separate tax parcels which have been owned or encumbered by easements for railroad, high voltage electrical transmission lines and storm drainage. The railroad grade has been vacated, the high voltage power lines are present and will not be modified by Mr. Pierre and the City of Renton has an easement for the existing drainage channel through the subject site. (See Exhibit A "City of Renton Drainage Easement".) The site is presently vacant; contains no impervious surface improvements; and is covered with blackberry vines, low growing shrubs and native grasses. There are several existing (8-inch minimum diameter) deciduous trees located near the SW corner of the site. There is an existing onsite drainage ditch flowing from east to west at a grade of 0.007 ft/ft. (See Figure 2: "Existing Site Conditions".) Except for the elevated vacated railroad grade, the entire site and adjacent parcels are categorized as flat. (See Figure 3, USGS Quad Map.) Onsite soils are identified by the U.S. Soil Conservation Service (SCS) as Ur-Urban Fill (See Figure 4, Soils Map.) .) The Wetland Verification Report by John Comis Associates dated September 1996 identifies some of the onsite soils as SCS Puyallup (Py) and Renton (Re) which are Hydrologic Groups B and D respectively. The Hydrologic classification for stormwater runoff calculations has been defined though site exploration as Hydrologic Group C.

There is also approximately 0.23 acre of grassy area within the City of Renton right- of-way which drain into the existing onsite channel. No other offsite drainage flow appears to enter the ' subject site except for that conveyed from the east in the existing channel. (See Offsite Analysis, following.) 3.0 Offsite Analysis Offsite contribution to the channel consists of mostly undetained surface flow from a 44-acre upstream basin which enters the site via twin 48-inch diameter corrugated metal pipe(CMP) culverts and exits the site via a 66-inch diameter CMP culvert. Offsite areas contributing flow to the existing onsite channel are shown on"Figure 5 : Offsite Conditions". The offsite areas of contribution were delineated by American Engineering Corporation and verified on March 20, 1997 by City of Renton staff(Paul Lumbert and Mike Dotson)through the use of"As-Built" record drawings. American Engineering Corporation then performed field verification after meeting with the city for systems not clearly documented in available ' city records. Upon exiting the subject site, drainage flows west through 189 lineal feet(LF) of 66-inch CMP culvert (S =0.47%)beneath Oakesdale Avenue SW. At this point, additional surface flow from approximately 9,400 SF (0.22 acre) of paved area is collected and added to the total conveyance volume. The 66-inch CMP outfalls to a 20-foot wide by 40-foot long rip rap pad. The rip rap pad reduces flow velocity and erosion potential when surface flow from the 47-acre total basin joins the P-1 (Springbrook Creek) Drainage Channel. At this location in the channel, it appers the P-1 may convey surface water runoff from several thousand acres to it's outfall near the Metro Renton Sewage Treatment Plant. There have been no reports of recent flooding or overtopping of the P-I Channel at this location. The following assumptions were used for offsite basin flow volume and modeling: No upstream detention 25% landscaped surface cover at Cn 86 75% paved/impervious surface cover at Cn 98 Time of Concentration(Tc) calculated to point of inflow to subject site(west margin of Powell Avenue SW) 4.0 Detention Analysis and Design Stormwater flows for existing and potential Pierre-Grady Way site conditions were established using the Santa Barbara Urban Hydrograph(SBUH)Method and King County Rainfall Distribution Curves identified as USER 6 in the WaterWorks software program. - The City of Renton requires that post-development stormwater flows exiting the site for the 2-year, 10- year and 100-year, 24-hour storms be limited to the pre-development 2-year, 10-year and 100-year 24-hour flows. The WaterWorks computer program was utilized to calculate the pre- and post-developed flows for the site. The King County rainfall distribution curve is contained in Selection 6 USER1 in the WaterWorks rainfall distribution selection parameter. The following information was used in the analysis: 2 ' • l• ,_ \ , ‘ ''''_ ____' 1......, 230..1 .. r•-• - , ' • /. 1 [ 1 , 1 : 1 ' -I - N '..." ,.."D l . .se•••••••••• ..)..... .' ..000.......1" ! \ 0... .... \J. ,,,,,..............0•W W....:.

The owner initially proposes to apply for a City of Renton Grade and Fill Permit(April 1997). A nearby source of suitable, inexpensive fill will be available from construction scheduled to occur at the Metro Renton sewage treatment plant approximately one-quarter mile northwest of the Pierre Grady Way site. This fill will be available in early summer(late June/early July), before the rezone and Site Plan Approval processes could be completed to permit site development as proposed. Regardless of the outcome of the land use decision, filling this site to bring it up to grade, compatible with the adjacent street system, is important to its future development and productive use. To calculate developed surface water flows, it was assumed that approximately 68 per cent or 1.86 acres of the subject parcel will be covered by impervious surface after development occurs. Within a matter of weeks after submitting the Grade and Fill Permit application,the owner plans to submit a request for rezone and Site Plan Approval,to pursue actual development plans for the site. A preliminary site plan is included in this report as Figure 6,"Developed Site Conditions." The estimated quantity of new impervious surface area in the developed condition is approximately 82,330 sq ft(1.87 acres), which is equal to approximately 68 percent of the site. This Storm Drainage Report will be revised, if necessary,to address the specific site development proposal, and a separate Environmental Checklist will be prepared at that time to address in more detail the impacts of, and mitigation for, site development. 4.4 Developed Conditions Flow Results (See Appendix B for WaterWorks output) Onsite Flows following Site Development Design Storm Developed Release Rate 2-yr, 24-hr 1.04 cfs 10-yr, 24-hr 1.65 cfs 100-yr, 24-hr 2.35 cfs 4.5 Detention System Information Based on current City of Renton detention design standards, the detention volume required to maintain the pre-developed 2, 10 and 100-year flows for the potential site conditions would be approximately 2,733 ' cubic feet. (See Appendix B, WaterWorks Calculation Sheets.) The purpose of stormwater detention storage is to alleviate downstream flooding and erosion which may result from increased surface water flow attributable to the introduction of impervious surface areas. The 2.74-acre project site location at the end of the drainage sub-basin suggests that detention storage may be ineffective. If site runoff were undetained following introduction of 68%impervious area,the 100-year, 24-hour rainfall event would equate to a sub-basin stormwater flow increase of 0.61 cfs. It seems unlikely that this amount of flow increase would result in adverse downstream effects. Existing conveyance systems have the capacity to receive this runoff. Therefore, we request that detention requirements be waived for this site. Please note that the existing drainage easement granted over and across the subject site to the City of Renton waives detention requirements for this site. (See ' Appendix A,Drainage Easement,Item#13) This report provides technical substantiation for this waiver.

DEMO ODDt PUB 0001Y LOCATOR - U POOR WINED TO IN 10 FONAL APPLICATOR Pierre-Grady Way Site Technical Information Report JOB NO. 9703 - Developed Site Conditions - Figure 6 SST ' 1 OF 1 proposal consists of enclosing the existing open drainage swale within a piped system capable of conveying both offsite and onsite stormwater flows resulting from the 100-year,24-hour rainfall event for developed conditions. It is' the intent of the owner to provide surface water quality treatment for onsite flows generated by areas subject to vehicular traffic in the developed conditions. This will be provided once construction is approved through the use of low flow splitting devices in catch basins which will direct flows resulting from the 2-year, 24-hour rainfall event to grass-lined biofiltration swales located near the outer edges of the property. In general, the biofiltration swales will direct surface flow to the 66-inch - ' CMP outfall at the west end of the site. Actual design for water quality treatment facilities will occur after the rezone and site plan approval decisions are issued. At this time, the owner proposes to fill and grade the site, construct adequate conveyance facilities for the interim condition, and to revegetate site'with grass and border landscaping along city rights-of-way. Proper Erosion and Sedimentation Control practices to be implemented during filling and grading will prevent sediment from entering the existing drainage system (See Section 9.0, below). We also respectfully request that until proposed site plan and construction documents are approved and since no impervious surface will be constructed as part of grading and filling, no water quality treatment facilities over and above the proposed grass re-vegetation and filter fabric fences which will remain until site is developed be required at this time. Appropriate water quality facilities will be designed as part of a separate permit. It is Mr. Pierre's intent to construct site improvements including water quality facilities late 1997. --I 5.01 n Co veyance System Analysis and Design To fill over the existing conveyance swale and develop the subject site, the conveyance facilities must be sized per City of Renton standards to convey both the offsite and onsite surface water flows through the subject property. Normal design parameters indicate that culverts should be sized as a minimum to convey the 25-year, 24-hour event. The pipe and surrounding system should then be analyzed for flooding during the 100-year, 24-hour event. No flooding of public streets is allowed. Some onsite surface ponding • occurring as the result of the 100-year, 24-hour rainfall event is allowed by the City, but is reviewed and approved or denied on a case-by-case basis. 1 A conveyance system sized for surface water flow from both on- and offsite developed conditions during a 100I year, 24-hour storm event will be designed and constructed on the Pierce Grady Way site. The total flow which must be conveyed is as follows : Offsite Area 1 100-yr, 24-hr 3.50 cfs Offsite Area 2 100-yr, 24-hr 7.70 cfs Offsite Area 3 100-yr, 24-hr 13.05 cfs Offsite Area 4 100-yr, 24-hr 0.26 cfs Onsite Developed 100-yr, 24-hr 2.35 cfs Total 100-year,24-hour flow to convey 27 CFS A single 48-inch diameter CMP culvert sloped at 0.007 ft/ft (slope available on project site in existing drainage channel) has a flowing full capacity of 65 cubic feet per second (CFS), which is more than adequate for the calculated 100-year, 24-hour flow conveyance requirement with no overtopping. Existing stormwater conveyance facilities which flow onto the site are twin (2) 48-inch diameter CMP culverts (total flowing full capacity of 130 CFS). The existing system appears to be greatly oversized. .It is assumed that the additional storage available in the system exists for flood storage. For system consistency, as part of the filling and grading activities, the owner proposes to continue the existing twin (2) 48" diameter CMP culverts through the site. 5 • r 6.0 Special Reports and Studies Three reports have been prepared relating to Pierre Grady Way project site in addition to this Stormwater Drainage Technical Information Report: Geotechnical Engineering Investigation American Engineering Corporation April 1997 Environmental Assessment Environmental Hazards Control September 1996 Wetland Verification Report John Comis Associates September 1996 The;Geotechnical Engineering Investigation report makes recommendations with respect to existing soil properties, placement of fill material on the site, and foundation and slab design parameters. The Environmental Site Assessment was prepared to address subsurface investigations at and in the near vicinity of the old railroad grade. No Environmental Hazards were identified on the subject site. The Wetlands Report was prepared by a wetlands specialist to verify the presence or absence of wetlands on or within 100 feet of the subject site. No regulated jurisdictional wetlands occur within the specified study area. These reports have been submitted to the City of Renton with the Grade and Fill Permit. 7.0 Basin and Community Planning Areas The project site is located in City of Renton Grid Section 4324 NE 1/4. The City of Renton has an extensive set of as-built records pertaining to water, sanitary sewer and storm drainage systems that utilize this grid system. This site is entirely contained within the Black River Drainage Basin. The Pierre Grady Way site is located within the City of Renton Comprehensive Plan Employment Area- Valley (EAV) designation. The EAV designation is intended to provide for a mixture of commercial, office and industrial uses. The proposed auto retain/service/rental uses fall within the range of uses indicated for the EAV designation. 8.0, Other Permits To the best of our knowledge, the following list of permits/actions are required for development.of this site Permits/Approval Required for Permits/Approvals Required for Site Grading and Filling: Site Development: SEPA Determination for Grade and Fill Permit Rezone Grade and Fill Permit SEPA Determination for Rezone and Site Plan Approval Construction Permit for Grading and Drainage Site Plan Approval Engineering Plan Approval Construction Permits -Utilities and Sitework Building Permit 6 I ! . 9.0 Erosion and Sedimentation Control Erosion and sediment control during site filling, grading and construction will be accomplished through the use of Best Management Practices BMP's as outlined in the "Stormwater Management Manual for the Puget Sound Basin," (SWM). It is likely the BMP's will include the installation of silt fencing at the site perimeter, stabilizing exposed soils and revegetating the site as soon as practicable upon completion of grading. It is proposed that the filter fabric fencing remain in place and be maintained until site development activities including landscaping have been completed. Erosion and sedimentation control measures also include provision for the cleaning of city streets if they become dirty as a result of construction activities. The contractor will be required to wash and sweep City streets on a regular basis ( ! throughout sitework and building construction. This will minimize siltation in downstream facilities. 1 Please refer to civil drawing sheets 3 and 4 of 6 for proposed Temporary Erosion and Sedimentation Control. 10.0 Operation and Maintenance - Theimanner in which project related drainage facilities will be maintained is described in table form in Appendix C, "Operation and Maintenance BMPs." -- I 7 Appendix A Existing City of Renton Drainage Easement is .` , r: .. . y .a...n.i•..•. • �• i :. ;::t..:yam• • N . �bCD AGREEMENT AND EASEMENT FOR DRAINAGE ' • • THIS AGREEMENT made. this (off dayof fil , 5. • • '—... .4!. :...- . between PUGETINC �- o ' ' " t98 • • • WESTERN, IN_.; a wash�nGton corporation ("Puget � � � . • _ _ • Western" herein), and CITY OF RENTON, ("Grantee" herc ,n); • 4 : . . . , • WHEREAS, Puget Western is the owner of a parcel of land in i '. ;:.. : the N.E. 1/4 of Section 24, Township 23 North, Range 4 East, • W.M., Ring County, Washington; and WHEREAS, Grantee desires an easement for a drainage channel • • ill • across Puget Western's land at a location more specifically - • . •!: . described herein below; !

Introduction A. General This report presents the results of our geotechnical investigation for the Jamie Pierre SW Grady Way site located on SW Grady Way between Oakesdale Avenue SW and Powell Avenue SW in Renton,Washington(See Figure 1,Vicinity Map). The purpose of our investigation was to evaluate the foundation soils and provide recommendations concerning the geotechnical engineering aspects of site conditions. American Engineering and its staff have performed several geotechnical studies in this area. We are 1 , familiar with site conditions and alternative development concepts being considered for this property. Conditions generally require pile foundations since the foundation soils are generally loose and subject to potential liquefaction and settlement. B. Project Description The likely development scenario at the time of this writing is a three—story,5000—square foot footprint structure with a large parking area(See Figure 2). The structure is to be located on the northeast corner of Oakesdale Avenue SW and SW Grady Way. The parking area will be located on filled ground over the existing drainage channel and under the electric transmission lines crossing the property. Access to the site will be from new driveways to be constructed on SW Grady Way(two)and Oakesdale Avenue SW(one). Building loads are anticipated to be about 600 psf dead load with combined active and dead loads of 1000 psf. The structure is proposed to be constructed with a steel frame and pile foundation. Alternatively, a 20,000 square foot building may be constructed on the north side of the property. This i single-story structure would be placed on fill,and may potentially be placed on wide,spread-footings if bearing loads are low. The site has not been graded since abandonment of an old railroad grade on the nortern parcel. A dense growth of vines and shrubs covers the site. Recent activities have flattened many of the vines;however,a thick mat of organic debris covers the entire site. 1 11 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April 4, 1997 � I C. Scope of Services The scope of work for this geotechnical investigation included a site visit;drilling,sampling,and testing a total of eight(8)holes (Figure 2);engineering analysis for settlement and pile embedment; and preparation of this report. Data obtained and the analysis performed were for the purpose of providing design and construction criteria for site earthwork,building foundations,slab-on-grade floor,and pavements. This report has been prepared in accordance with generally accepted geotechnical engineering practices, and in accordance in agreement with Jamie Pierre for the exclusive use of Mr. Pierre and his consultants for specific application to the commercial structure and parking area. In the event there are any changes in ownership,the nature,design or location of the proposed commercial structure and parking area,or if any future additions are planned,the conclusions and recommendations contained in this report shall not be considered valid unless 1)project changes are reviewed by American Engineering Corporation,and 2)the conclusions and recommendations presented in this report are modified or verified in writing. Reliance on this report by others must be at their risk unless we are consulted in the use or limitations of this information. We cannot be responsible for the impacts of any changes in environmental standards without further consultation. We can neither vouch for the accuracy of information supplied by others nor accept consequences for unconsulted use of ! ,r segregated portions of this report. II. Site Description and Investigations The Pierre Grady Way site has been subject to extensive,long-term development since the construction of an old abandoned railroad grade through the property probably as early as the turn of the century. Subsequent development has included construction of the electrical transmission line towers,development of SW Grady Way, excavation of the drainage channel and grading of industrial property north of the site. The property is covered by a dense mat of blackberry vines and shrubs. A few trees are present in the area planned for the three-story structure. The organics form a dense mat,locally up to 12 inches,thick. Imported fill was used to construct the railroad grade and also placed to the north. These deposits will be regraded duringthe proposed fill andgrade operations. The fills have raised thepresent_ gr p P P ground surface north of the drainage channel more than 10 feet above the bottom of the channel floor. While there is no visible evidence I � 2 Q I , Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April4, 1997 of runoff within the site boundaries into this drainage channel,water flows through it at 0.5 to 1.0 cfs(See the Technical Information Report, Stormwater Drainage,American Engineering Corporation,April 1997). A. Surface The subject site is located on the northeast corner of Oakesdale Avenue SW and SW Grady Way. The south side of the property is about 6 feet below the level of SW Grady Way. The drainage channel is 4 to 5 feet lower than the existing elevation of the site,and runs east-west across the length of the property. The site is about 2.74 acres in size,crudely rectangular,750 x 200,with a 120 x 300 rectangle jutting northward from the longer dimension. Surrounding land development,drainage and old fills have made site access and development difficult. A low—level powerline crosses under the main high voltage lines very close to the ground on the western one-third of the site. Care must be taken during site grading to avoid this potential hazard. { B. Subsurface Borings drilled onsite revealed approximately 12 feet of marginally plastic,silty clay soil(Cl). This layer extends the length of the site,east to west,and was found in all borings (see Figure 3). Underlying the silty clay is a thick layer of loose to dense silty sand that extends to a depth of 25.5 to 27.5 feet within the area proposed for the three-story building. This material is potentially liquefiable under seismic load. However,pore pressure dissipation rates are favorable to the extent that the potential is slight. Below 25.5 to 27.5 feet,a very dense, gravelly sand was encountered that extends to the greatest depth penetrated: 51.5 feet. The soils above 27 feet were deposited by streams and flood waters of the abandoned Black River channel, located west of the site,that used to drain Lake Washington. Surface runoff now drains to the Green River at Tukwila,and ultimately to Puget Sound. These underlying shallow soils are saturated and potentially subject to disturbance from settlement and seismic activity. Soils encountered below 27 feet are believed to be deposits of glacial outwash. No bedrock was encountered;the depth to bedrock is expected to be greater than 100 feet below the site. C. Groundwater The water table in this area is in contact with the bottom of the drainage channel through the site. This level will be about 10 feet below final grade following the proposed grade and fill action. Groundwater will maintain saturation of the loose,silty sand underlying the property,but is not expected to rise appreciably above the drainage channel bottom elevation of approximately 10 feet ASL. None of the fill planned for the site is expected 3 r { Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April 4, 1997 r to be placed within the groundwater table zone. The groundwater table was encountered in the borings but the holes were not left open a sufficient length of time for the water levels to stabilize. D. Seismicity Earthquake intensities vary depending upon the magnitude of the earthquake and the distance of the project site from the epicenter or causative fault. The site could be subject to substantial seismic events if past history represents the regional pattern. Four earthquakes between 5.5 and 7.0 magnitude have been centered within 20 to 50 miles of the site. Some of these earthquakes caused significant damage in the Olympia and Seattle area in 1949 and 1965,respectively. Development at that time in the vicinity of the project site at that time was limited i - with few engineered structures;therefore,there were no reports of local damage. Site conditions are conducive for shaking and potential liquefaction. These forces must be considered in design. The Uniform Building Code(UBC) Seismic Zonation Map(1994)places the site in Seismic Zone 3. The UBC recommends that the seismic zone factor(Z)be 0.30. Site coefficients are: soil type, S3,with an"S"factor - of 1.5. Bedrock is located approximately 100 feet below ground surface,and very dense soils were identified at a depth of 26.5 to 27.5 feet. Soils below 27.5 feet have a seismic shear wave velocity in excess of 500 feet per second. 1 'y Generally,soils that are susceptible to liquefaction are loose,saturated,uniform grades,fine-grained sand that lie within 60 feet of the ground surface. The soils identified onsite below 27.5 feet generally consist of dense to very dense coarse sand and gravel to an estimated depth of about 100 feet. These soils will not liquefy under earthquake loading. I � III. Conclusions and Recommendations A. General It is our opinion that the site is suitable for construction of the proposed three-story commercial structure , from a geotechnical engineering standpoint. The presence of dense to very dense sand below a depth of 27.5 feet is the primary consideration for site suitability. The loads incurred from fill,traffic, and pavement will result in settlement of less than two inches overall,and less than one inch of differential settlement from the soils within ' the upper 27 feet. Structural loads are expected to bear on the very dense sands at depths greater than 27.5 feet. 4 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April4, 1997 1 -' The commercial structure proposed at the northeast corner of Oakesdale Avenue SW and SW Grady Way may be supported on a pile foundation. We recommend a floating slab floor if some differential settlement is tolerable. Otherwise,a structural floor is recommended. This foundation may be constructed after the present surface is filled to fmal grade and when a dry working surface is established. As long as the fill is not to be used for structural bearing,the fill may be placed on top of the existing vegetation surface following mowing and 11 removal of trees and debris. The area can then be backfilled with fill compacted to a minimum of 90 percent of maximum dry density in the upper 50 percent of the fill. The engineered fill should consist of dry,compacted, imported structural fill with the source previously approved by a geotechnical engineer. Slab support can be provided by existing soils provided some settlement can be tolerated. If the proposed structure is moved to the north side of the property and constructed as a one-story facility,the low bearing capacity of the native soils must be taken into consideration. A base course of imported soil will be required to raise the slab elevation to fmal grade inside of the footing area. All base course soil must be compacted to 90 percent of maximum dry density. The parking lot area will be constructed on fill up to 10 feet thick. The present surface may be stripped of wet,soft sediments. Fill can be placed over organic debris following the mowing of surface vegetation. Compaction of the engineered fill should start after two feet of fill has been placed over the present surface. Fill control should conform to the requirements of Section B.5 and B.6 of this report. We recommend that our firm review the final design and specifications to confirm that earthwork and foundation recommendations presented in this report have been properly interpreted and implemented in the design and specifications. We also recommend that a representative from American Engineering Corporation be present onsite during foundation excavation to verify that subsurface conditions are as anticipated,and that competent bearing soil is exposed as anticipated. We can assume no responsibility for the misrepresentation of our recommendations if we do not review the plans and specifications,and monitor the earthwork. The conclusions and recommendations presented in this report should be incorporated in the design and construction of the project to minimize any soils and/or foundation-related problems. Detailed earthwork and foundation recommendations for use in design and construction of the project are presented in the following I ; sections. 5 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site fl April 4, 1997 f � { B. Earthwork 1. Clearing and Site Preparation The building and parking areas should be cleared of all obstructions and debris. Holes resulting from the removal of large underground obstructions should be cleared and backfilled with suitable imported material. We recommend that fill be placed after existing vegetation is mowed or compacted into the surface. The initial two feet of fill will not require compaction. This work should be carried out under the observation of a geotechnical engineer. After the initial two feet of fill is placed,the remaining fill should be placed in accordance with Section B.6, Compaction(below). No stripping is required. All loose wood debris,trash,tree limbs and stumps should be removed. 2. Temporary Excavations Foundation excavation depths including utility trenches should comply with local,state,and federal safety regulations. Specifically,the current OSHA Health and Safety Standards for excavations,29 CFR Part 1926, should be followed. We understand that these regulations are to be strictly enforced,and if they are not closely followed,the owner and contractor could be liable for substantial penalties. The contractor's"responsible person as defined in 29 CFR Part 1926" should evaluate soil exposed in excavations as part of the contractor's safety procedures. II 3. Subgrade Preparation After the completion of clearing and filling with the initial two feet of engineered fill in areas to receive structural fill,slabs-on-grade or pavement,the surface should be scarified to a depth of 6 inches,moisture- conditioned to(or slightly above)optimum water content,and compacted to structural fill requirements. 4. Engineered Fill Layer Any footings and slabs will be founded in engineered fill. We recommend that any engineered fill layer be a minimum of two feet thick under footings and paving. Any existing grades onsite that are presently at grade should be over-excavated to two feet below grade,scarified,and backfilled using imported structural fill. The excavated onsite material which meets the requirements of Fill Material(Section III.B.5 of this report)should be stockpiled and later used as fill. The exposed surfaces should then be prepared in accordance with Section III.B.3 6 jl Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April4, 1997 ( ! of this report: Subgrade Preparation. Onsite soil or imported fill should be compacted in accordance with Section III.B.6 of this report: Compaction. S. Fill Material Based on our surface reconnaissance,it is our opinion that the excavated railroad grade soils can be recompacted if they are at optimum moisture content and if construction takes place during dry weather. Any excavated soils that do not meet the requirements of structural fill should not be used or mixed with any fill material,and should be disposed of offsite or used only for landscaping. All fill placed at the site including onsite soil should not contain rocks or lumps larger than 6 inches in greatest dimension with not more than 15 percent larger than 2.5 inches. Onsite soil that contains rocks greater than 2.5 inches nominal diameter should be mechanically raked,screened,or replaced by imported fill with the r--, correct size distribution. In addition,imported fill should be predominantly granular with a plasticity index(PI) l__ of 12 or less. All fill material should be placed at,or slightly below the optimum moisture content. If the materials are too wet to be compacted to 90 percent of maximum dry density,it will be necessary to dry the fill material,mix with lime,or replace the soil to achieve required compaction. Imported structural fill will be observed and tested using modified Proctor Compaction tests to determine the required compaction efficiency to attain the required 90 percent of maximum dry density. The quality of the structural fill will determine the density of compaction tests required during fill construction. 6. Compaction All structural fill should be compacted to at least 90 percent relative compaction as determined by ASTM Designation D1557-78. Fill material should be spread and compacted in lifts not exceeding 8 inches in uncompacted thickness. 7. Surcharge The native soils underlying the site consist of non-plastic clay and fine sand that has the potential for settlement. Our analysis shows that settlement could be up to 2 inches with differential settlement of up to 1 inch. If this level of movement is not acceptable,we recommend that the area outside of the drainage way and abandoned railroad grade be surcharged by 2 feet of imported soil. The surcharge soils may later be used to bring the rest of the site to final grade. 7 • • I Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April 4, 1997 In the event that a single-story structure is located on the northern portion of the property,we strongly recommend that the area outside of the railroad grade be surcharged for at least 90 days to reduce the potential for differential settlement. Settlement gages should be installed to determine when the settlement reaches a suitable level. If 3 feet of surcharge is used,suitable settlement may be obtained in a shorter interval. 8. Trench Backfill Utility trenches can be backflled with native soils or imported fill placed in lifts of approximately 6 inches { in uncompacted thickness. Thicker lifts can be used provided the method of compaction is approved by a representative from American Engineering Corporation and the required minimum degree of compaction is achieved. L_.1 The backfill material should be compacted by mechanical means to a minimum degree of compaction of 90 percent. Imported sand can be used for backfilling trenches provided it is compacted to at least 95 percent and sufficient water is added during the trench backfilling operations to prevent the soil from bulking during compaction. The upper 3 feet of trench backfills in slab and pavement areas should be compacted to at least 95 percent relative compaction for onsite soils and where imported sand backfill is used. l ` 9. Drainage Interim drainage control measures during construction,and permanent facilities in the completed development, are proposed by the applicant. (See the Technical Information Report:Stormwater Drainage; American Engineering Corporation,April 1997). Onsite soils have been classified using the Unified Soils Classification System(USCS). Surficial soils are non-plastic to slightly plastic clay to a depth of about 12 feet. This soil mantles practically all of the site. The clay is underlain by medium to fine,loose to dense sand. The surficial soil would be classified as Type C soil with a moderate to high runoff potential. The soil group mapped by SCS is"Urban"(Ur). Because of the shallow water table located at the base of the clay topsoil at an approximate depth of 12 feet,that the site is poorly configured for rapid drainage,and that the soil exhibits a slow water conductivity,the natural drainage conditions are very poor. Regrading new slopes to catchment facilities will reduce soil saturation. Containing existing stream flow will reduce natural surface water infiltration and minimize additions to the water table. 8 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site Apri14, 1997 I � 9.1 Drainage Water should not be allowed to pond in any areas where foundations,slabs,or pavements are to be constructed. Water that is encountered during foundation excavation should be pumped out of the excavations. Alternatively,excavations can be sloped toward one or more shallow sump pits. The collected water should then be diverted to a positive and permanent point of discharge. 9.2 Drainage Measures i Long-term drainage measures should include(1)grading,(2).perimeter footing drains,and(3)slab moisture I' barriers. Design of a stormwater detention system is not part of this study. Each of these is discussed below. 9.2.1 Grading Positive surface gradients should be provided adjacent to the building to direct surface water away from foundations and slabs toward suitable discharge facilities. We recommend that the ground be sloped at a minimum 3 percent gradient for a distance at least 10 feet away from the structure. Similarly,roof downspouts should be connected to suitable discharge facilities. Ponding of surface water should not be allowed adjacent to the structure or on pavements. 9.2.2 Perimeter Footing Drains We recommend the installation of footing drains around the perimeter of the structure. These drains should consist of a 4-inch minimum diameter,perforated or slotted,rigid drain pipe laid with the perforations or slots 1 j facing down at,or just below,the invert of the footing with a gradient sufficient to initiate flow. The drain line should be bedded on,surrounded by,and covered with a free-draining material that meets the requirements of Washington State Department of Transportation(WSDOT)Standard Specifications, Section 9-03.12(2). See Table 1. Table 1. WDOT Standard Specifications,Section 9-03.12(2) U.S.Sieve Size Percent Passing* 4" square 100 1/4"square 25—70 No. 200 5.0 max. *All percentages are by weight. A typical drain detail is provided on Figure 4. Once drains are installed,with the exception of the upper 6 inches,the excavation can be backfilled with a granular fill material(native soil or imported fill). The surface 6 inches of fill should consist of compacted and 9 t �' Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April 4,1997 relatively impermeable soil. It can be separated from the underlying more granular drainage material by a layer of geofabric or visqueen. The surface should be sloped to drain away from the building wall. Alternatively,the surface can be sealed with asphalt or concrete paving. All footing drain lines should be connected to a positive discharge,i.e. storm drain or infiltration system. 10. Slab Moisture Barrier To mitigate the passage of moisture through the foundation slab,we recommend that a capillary break consisting of 4 inches of free-draining gravel covered with an impermeable membrane moisture barrier(10 mil visqueen)be placed between the subgrade soil and the slab(Figure 5). The membrane should be covered with 2 inches of moist sand for protection during construction. t 11. Construction During Wet-Weather Conditions If construction proceeds during or shortly after wet-weather conditions,the moisture content of onsite soils will be above optimum. Consequently,subgrade preparation,placement and/or reworking of onsite and structural fill will not be possible. Alternative wet-weather construction recommendations can be provided by American Engineering Corporation in the field just prior to construction,if appropriate. 12. Guide Specifications All earthwork should be performed in accordance with the Guide Specifications for Site Earthwork presented in Appendix C. Appendix D presents the Guide Specifications for Asphalt Paving. These specifications are general in nature. Final specifications should incorporate all recommendations in this report. 13. Monitoring Settlement monuments should be used to monitor settlement as fill is placed onsite. Six gages should be placed at locations of deepest fill and surveyed bi-weekly during filling and after completion until deformation ceases or the deformation level is less than 10 percent of the previous measurement period. The fill will require field testing to ensure adequate compaction effort. We recommend test services in each layer using a nuclear density gage operated by a certified soils technician. 10 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April 4, 1997 C. Foundation Support 1. Spread Footing Foundation areas should be prepared as described in Sections III.B-3 and III.B-4 of this report. Any conventional footings can be designed on the basis of the following criteria: • Allowable bearing pressure on compacted structural fill or concrete lean mix,including all dead and live loads 1,000 psf • A one-third increase in the bearing capacity can be used when considering short term transient loads. • Minimum depth of perimeter footing below adjacent final exterior grade to account for frost penetration 18 inches Continuous footing should be designed with adequate top and bottom reinforcing to provide structural continuity and permit spanning of local irregularities. Footings located adjacent to other footings or utility trenches should bear below an imaginary 1.5:1 (horizontal to vertical)plane projected upward from the bottom edge of the adjacent footings or utility trench. 2. Piles Because of the potentially liquefiable fine to medium sand layer located about 11.5 to 28.0 feet below ground surface,we are providinginformation for optionalpile support of the proposed structure. The site soil P PP P P profile consists of approximately 12 feet of sandy clay and 16 feet of saturated medium to fine,loose sand(N= 8)underlain by very dense,coarse sand to the maximum depth of exploration: 51.5 feet. The following table(Table 2)provides pile embedment depths into the bearing soils and pile lengths below existing ground surface based on present soil conditions. These lengths take into consideration the effects of the structural load and downdrag of the soil layer overlying the loose sand. Table 2. Pile Embedment and Pile Lengths Pile Bearing Capacity,kips 20 30 40 50 Embedment Length Embedment Length Embedment Length Embedment Length Pile Diameter ft ft ft ft ft ft ft ft 12 inches 13 41 20 48 26 54 33 61 16 inches 10 38 16 44 20 48 25 53 20 inches 8 36 12.5 40.5 17 45 20 48 11 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site r—„ April 4, 1997 These pile lengths are based on the following soil parameters: Modulus of subgrade reaction 10 pci Coefficient of Friction: 0— 12 feet 15E 12—27.5 feet 35E 27.5 feet—Below 45E Wet Density: 0— 12 feet, 110 pcf 12—27.5 feet 100 pcf 27.5 feet—Below 120 pcf Dry Density: 0— 12 feet 120 pcf 12—27.5 feet 125 pcf 27.5 feet—Below 135 pcf Cohesion: 0— 12 feet Concrete pile 250—500 psf Steel pile 250—500 psf Piles will extend into the native soils that exhibit Standard Penetration Test(SPT),N—values of 30 or greater. As the structure design is not yet defined,we have not yet determined whether to recommend augercast, concrete or steel piles. We recommend that the depth to zero lateral deflection be within the lower bearing layer and the pile caps be tied together so the piles maintain a high level of stiffness. The reinforcing cage,if augercast piles are used, should extend a minimum of two feet below the point of zero deflection,with the center bar extending to the bottom of the hole. Steel or concrete reinforced piles may be driven to the recommended embedment lengths provided the driving blow count indicates adequate bearing is attained. Appendix B of this report contains testing results for the cone penetrometer tests(CPT). These tests indicate sand lenses in the interval between 13 and 27 feet that may contribute additional bearing capacity to the piles. However,greater emphasis has been placed on the N—values from the Standard Penetration Tests(SPT) that show values below 8 to about 22 feet in boring B-1,and to about 12 feet in B-2. The CPT tests in three locations show bearing sands at depths of 26.5 and 27.5 feet from west to east across the site. A conservative -- depth of 28 feet has been used for pile design recommendations. 12 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site April 4, 1997 If the structural engineer requires additional information for design,please contact us. 3. Slab—on—Grade Slab-on-grade floors can be used with conventional shallow foundations provided that interior slab foundation zone is placed on structural fill or crushed rock(Figure 5). Slab-on-grade subgrade surfaces should be proof-rolled to provide a smooth unyielding surface for slab support. Slab reinforcing should be provided in accordance with the anticipated use and loading conditions. If the slab is supported on the engineered fill,slab damage,in the form of warping,cracking,and separation caused by differential settlement,may occur. The slab will then require periodic maintenance. If the situation is acceptable from an economic standpoint,then this option for slab support can be used. We recommend that the slab be reinforced with#4 rebars, 18 inches on center. However,the slab should be designed by a structural engineer for the anticipated use and loading. We recommend that a structural slab be constructed in the proposed structures. This method would minimize damage resulting from differential settlement. If settlement can be tolerated, the slab could be floated on the engineered fill subgrade. A joint should be established between pile columns and the slab to control fractures. 4. Settlement The clayey topsoil and potentially liquefiable fine sands of foundation soils indicate that settlement could be as much as two inches with differential settlements of about one inch. All base courses under paving must be compacted to 95 percent or maximum dry density. We expect that a minimum of two feet of engineered fill compacted to at least 90 percent of maximum dry density will underlay the entire parking area. Some areas will have up to 10 feet of fill. Differential settlement of the parking area will be contingent on the efficiency obtained in utility trench backfilling. 5. Resistance of Lateral Loads Proposed building lateral load resistance can be accomplished by installing grade beams between pile caps, the stiffness of the piles,and soil resistance. An upper soil layer friction coefficient of 0.25 is considered applicable. 13 Geotechnical Engineering Investigation AEC#9703 SW Grady Way Site Apri14, 1997 D. Pavements • Pavement subgrade areas should be prepared as described in Sections III.B-3 and III.B-6 of this report, Subgrade Preparation and Compaction. We recommend that the pavement section for light automobile traffic consist of two inches of asphalt concrete over four inches of compacted crushed rock base that meets the requirements of WDOT Standard Specifications,Section 9-03.9(3). In areas of the site to be used by heavy truck traffic,we recommend four inches of asphalt over six inches of crushed rock. The latter section may be appropriate in the parking area where heavy delivery trucks will travel. The above pavement section recommendations assume that subgrade soils will remain relatively dry and stable prior to placing any fill,base course,or paving,and that all utility trenches will be backfilled with soil using the recommended degree of compaction. IV. Construction Observation The analysis,designs,opinions,and recommendations submitted in this report are based upon our site observations,knowledge of the site and experience with projects within the area. Variations of subsurface conditions from those analyzed or characterized in the report are possible and may become evident during construction. In that event,it may be advisable to reevaluate certain analyses or assumptions. We recommend that our firm be retained to provide geotechnical services during site grading,foundation excavation,subgrade preparation and backfilling to observe compliance with the design concepts,specifications, and recommendations presented in this report. Our presence will also allow us to modify the design if unanticipated subsurface conditions are encountered. • V. Report Preparation This report was prepared by R.J.

USA: Warren, NJ, Denver, CO, Pacheco, CA, Signal Hill, CA ASIA: Hong Kong Electric Cone Testing The cone penetration tests(CPT)were carried out by ConeTec using an integrated electronic cone. A 10 ton compression type cone was used for all of the soundings. This cone has a tip area of 10 sq. cm. and a friction sleeve area of 150 sq. cm. The compression cone is designed with an equal end area friction sleeve and a tip end area ratio of 0.85. A porewater pressure filter was located directly behind the cone tip. The filter was made of porous plastic and was 5.0 mm thick. Each of the porewater pressure filters was saturated in glycerin under vacuum pressure prior to penetration. Porewater pressure dissipation was recorded at 5 second intervals during pauses in penetration. The cone was also instrumented to record shear waves. The equipment and procedures for conducting the wave velocity measurements have been described by Robertson et al. (1986). The cone was capable of recordingthe following parameters at varying depth intervals: Tip Resistance (Qc) Sleeve Friction (Fs) Dynamic Penetration Pore Pressure(Ut) Temperature (T) Cone Inclination (I) Shear and compression wave velocities (Vs) and (Vp) Resistivity (S2-m) The above parameters can be printed simultaneously on a printer and stored on a floppy disk for future analysis and reference. All cone penetration testing was carried out in accordance with ASTM D-3441. A complete set of baseline readings were taken prior to and at the completion of each sounding to determine temperature shifts and any zero load offsets. Corrections for temperature shifts and zero load offsets can be extremely important, especially when the recorded loads are relatively small. In sandy soils, however,these corrections are generally negligible. Graphical plots of all CPT data are presented with this report. The inferred stratigraphic profile at each CPT test location may be included with this report. The stratigraphic interpretations are based on relationships between cone bearing, Qt, sleeve friction, Fs, and dynamic pore pressure, Ut. The friction ratio, (Fs/Qt) is a calculated parameter which is used to identify the type of soil and hence gives an indication of its behavior. Generally, soft cohesive soils have high friction ratios, low cone bearing pressures and generate large porewater pressures during penetration. Cohesionless soils have lower friction ratios, high cone bearing pressures and generate little in the way of porewater pressure during penetration. The I I classification of soils is based on correlations developed by Robertson et al. (1986). It is not always possible to clearly identify a soil type based on Qt and Fs alone. Experience,judgment and analyses of porewater pressure generation during penetration and subsequent dissipation were used in arriving at soil type in these ambiguous situations.

Upon completion of the construction work,the Contractor shall certify that all compacted fills and foundations are in place at the correct locations,have the correct dimensions,are plumb,and have been constructed in accordance with sound construction practice. In addition,he shall certify that the materials used are of the types,quantity and quality required by the plans and specifications. C. Site and Foundation Conditions The Contractor is presumed to have visited the site and to have familiarized himself with existing site conditions and the soil report titled"Geotechnical Engineering Investigation for Proposed Les Schwab Facility",dated January 1997. The Contractor shall not be relieved of liability under the contract for any loss sustained as a result of any variance between conditions indicated by or deduced from the soil report and the actual conditions encountered during the course of the work. The Contractor shall,upon becoming aware of surface and/or subsurface conditions differing from those disclosed by the original soil investigation,promptly notify the Owner as to the nature and extent of the differing conditions,first verbally to permit verification of the conditions,and then in writing. No claim by the Contractor for any conditions differing from those anticipated in the plans and specifications and disclosed by the soil investigation will be allowed unless the Contractor has so notified the Owner,verbally and in writing,as required above,of such changed conditions. D. Dust Control The Contractor shall assume responsibility for the alleviation or prevention of any dust nuisance on or about the site or off-site borrow areas. The Contractor shall assume all liability,including court costs of co-defendant,for all claims related to dust or windblown materials attributable to his work. II. DEFINITION OF TERMS Structural Fill—All soil or soil-rock material placed at the site in order to raise grades or to backfill excavations,and upon which the Geotechnical Engineer has been sufficient tests and/or observations to enable him to issue a written statement that,in his opinion,the fill has been placed and compacted in accordance with the specification requirements. On-Site Material=Material obtained from the required site excavations. Import Material—Material obtained from off-site borrow areas. ASTM Specifications—The 1994 edition of the American Society for Testing and Materials Standards. Degree of Compaction—The ratio,expressed as a percentage,of the in-place dry density of the compacted fill material to the maximum dry density of the same material as determined by ASTM Test Designation D1557-78. APPENDIX C 1 III. SITE PREPARATION A. Clearing and Grubbing The contractor shall accept the site in its present condition and shall remove the area of the designated project earthwork all obstructions including and any other matter determined by the Geotechnical Engineer to be deleterious. Such material shall become the property of the Contractor and shall be removed from the site. Holes resulting from the removal of underground obstructions that extend below fmish grades shall be cleared and backfilled with structural fill. B. Stripping Where vegetation exists,the site shall be stripped to a minimum depth of six to eight inches or to such greater depth as the Geotechnical Engineer in the field may consider as being advisable to remove all surface vegetation and organic laden topsoil. Stripped topsoil with an organic content in excess of 3 percent by volume shall be stockpiled for possible use in landscaped areas. IV. EXCAVATION All excavations shall be performed to the lines and grades and within the tolerances specified on the project grading plans. All overexcavation below the grades specified shall be backfilled at the Contractor's expense and shall be compacted in accordance with the specifications. The Contractor shall assume full responsibility for the stability of all temporary construction slopes at the site. V. SUBGRADE PREPARATION Surfaces to receive compacted fill,and those on which concrete slabs and pavements will be constructed,shall be scarified to a minimum depth of 6 inches and compacted. All ruts,hummocks,or other uneven surface features shall be removed by surface grading prior to placement of any fill materials. All areas which are to receive fill material shall be approved by the Geotechnical Engineer prior to placement of any fill material. VI. GENERAL REQUIREMENTS FOR FILL MATERIAL All fill material must be approved bythe Geotechnical Engineer. The to material shall be a soil or soil- rock mixture which is free from organic matter or other deleterious substances. The fill material shall not contain rocks or rock fragments over 6 inches in greatest dimension and not more than 15 percent shall be over 2.5 inches in greatest dimension. On-site material having an organic content of less than 3 percent by volume is suitable for use as fill in all areas except where non-expansive import material is specified. All imported fill material shall be non-expansive with a plasticity index of 12 or less. VII. PLACING AND COMPACTING FILL MATERIAL All structural fill shall be compacted by mechanical means to produce a minimum degree of compaction of 95 percent as determined by ASTM Test Designation D1557-78. Field density tests shall be performed in accordance with either ASTM Test Designation D1556-64(Sand-Cone Method)or ASTM Test Designation D2922-81 and D3017-78 (Nuclear Probe Method). The locations and number of field density tests shall be determined by the Geotechnical Engineer. The results of these tests and compliance with these specifications shall be the basis upon which satisfactory completion of work shall be judged by the APPENDIX C Geotechnical Engineer. VIII. TRENCH BACKFILL Pipeline trenches shall be backfilled with compacted structural fill placed in lifts not exceeding 8 inches of uncompacted thickness. If on-site soils is used,the material shall be compacted by mechanical means to a minimum degree of compaction of 90 percent. Imported sand may also be used for backfilling trenches provided it is compacted to at least 95 percent. If imported sand backfilling is used,sufficient water shall be added during the trench backfilling operations to prevent the soil from bulking during compaction. In all building pad and pavement areas,the upper 3 feet of trench backfill shall be compacted to a minimum degree of compaction of 95 percent for on-site soils and imported sand backfill. IX. TREATMENT AFTER COMPLETION OF EARTHWORK After the earthwork operations have been completed and the Geotechnical Engineer has finished his observation of the work,no further earthwork operations shall be performed except with the approval of and under the observation of the Geotechnical Engineer It shall be the responsibility of the Contractor to prevent erosion of freshly graded areas during construction and until such time as permanent drainage and erosion control measures have been installed.

This was done to determine if any wetlands may exist in or around the Puget Power line right of way along the north side of SW Grady Way, between Oaksdale Avenue SW and Powell Avenue SW, along a large maintained drainage ditch which exists through this area. The site location is shown and ` described on the vicinity map (see Figure 1). I examined the site on September 10, 1996, to verify onsite and offsite conditions for possible wetland areas. Maps were also examined at the City Planning Department which show the subject area and possible wetlands within the City limits. No wetlands are shown on the inventory map in this area. This report documents my onsite analysis and a finding that there are NO regulated jurisdictional wetlands situated within the property boundary, or offsite within 100 feet of the property. This non-wetland determination is based on test plots taken along the topographic low areas of the site which are described in detail in this report. This report may be used to obtain environmental approval for the subject site. I believe these findings are correct and complete. If you have any questions concerning this report, please call me at your earliest convenience. Sincerely, ohn G.

On September 10, 1996, we conducted field investigations to locate possible wetlands in or near to the subject site. The field investigations were conducted by John G. Comis, Wetland Specialist, or under his direct supervision. The field investigations were conducted during normal dry weather conditions at the end of the growing season (Aug-Sept). Weather conditions on the date of the investigation were recorded in the field notes as: * partly cloudy to sunny, some rain past week, no rain past 24 hours; * generally 'dry'site conditions, no standing or surface water in ditches along the roadway, or in bottom of new offsite storm water retention pond to north side of site. Antecedent moisture condition at the site was recorded as"dry" (AMC=1.0). 2. SITE DESCRIPTION including Location, Size, Topography and Current Use. The subject site is the Puget Power line right of way along the north side of SW Grady Way, between Oaksdale Avenue SW and Powell Avenue SW, along a large maintained drainage ditch which exists through this area. This site is generally located north and east of the intersection of SW Grady Way and Oaksdale Avenue, in the incorporated area of the City of Renton. It is situated in the NE1/4 of Section 24, T23N, R4E,WM, King County, Washington. The site location is shown on the vicinity map(Figure 1). There are no unusual or difficult access problems to site. The current land use of the onsite area is for a power line right of way consisting of large metal tower structures and smaller wooden utility poles. A large drainage ditch is maintained through the length of the site; and an old abandoned railroad grade extends across the northerly portion of the site. Most of the site is overgrown by a dominant stand of Himalayan blackberries, mixed with various species of Oregon ash, Scott's broom, and Red alder. More about the this in the vegetation section of the report. There are no existing structures on the site except for the power line towers and utility poles. The surrounding land use consists of major City street arterials to the south and west of the site, and a large commercial development to the northeast. Powell Avenue SW appears to be a local access street into the development. Some undeveloped property is situated to the northwest of the site which has a second large drainage ditch separated from the site by forested uplands. The offsite area to the northwest was examined for possible wetlands and none were found in this area. 3. METHODS USED for Identifying and Delineating Wetlands. Methods used for identifying and delineating areas which are"jurisdictional"wetlands (i.e. scientifically defined areas based on the 3-parameters of vegetation, soils, and hydrology)follow the 1987 Corps of Engineers Wetlands Delineation Manual (Technical Report Y-87-1, January, 1987). The selection of a specific method or procedure follows: 1)the"routine onsite determination method"for undisturbed and non-problem area wetlands; 2)the"offsite determination method"for areas within 100'of the property boundary; and/or 3)the"disturbed area and problem area wetland determination procedures"for areas with disturbed vegetation, soils or hydrology. Representative test plots are used onsite to determine if a jurisdictional wetland exists within the P property boundary, or to verify non-wetland conditions. If an area is generally uniform and does not appear to change across an onsite area, then fewer test plots are evaluated. If an area is determined to clearly be a non jurisdictional wetland area based on topography, vegetation or soil conditions (see definitions in Appendix 2 for details), then notes are shown on the field note sketch map, field data sheet or site plan map to indicate these conditions exist. If and area is 3 disturbed, then more test plots are used to document the presence or absence of the wetland conditions. Disturbances include cultivation, mowing or clearing and grubbing in marginal areas. Research of best available map information was done to obtain data on the presence or absence of possible wetlands in the site area. Map data was examined which included previous studies such as the City's Wetland Inventory map, FEMA flood study map, SCS soils survey map, and Drainage map. This information is not provided with this report at this time but may be provided upon request to document the offsite conditions. No offsite wetlands are shown on these maps. Test plots are examined at locations concentrating at the lower side of the site. The test plots include holes dug by hand 18 inches deep to examine soil horizons, and verify surface and groundwater hydrology. The specific soil cores and vegetation data for test plots are recorded on Field Data Sheets included with this report in Appendix 1. Offsite areas are investigated within 100 feet from the property boundary lines. This distance represents the largest buffer width required by the City of Renton's Wetlands Management Regulations, beyond which no further analysis or mitigation is required. A detailed description of methods used, key definitions, and standards for wetland analysis are included with this report in Appendix 2. Please note that the interpretation of the site may vary depending on seasonal differences and long-term climatic conditions(i.e. drought or flood). The non-wetland determination is based on existing conditions found in the site area, including man- made changes such as drainage and maintenance of the ditches and culverts established in the onsite and adjacent offsite areas. 4. FLAGGING Identified for Test Plots Areas. The test plots are flagged with blue and green ribbon, tied to vegetation. Test Plot#1 is located along the south side of the large drainage ditch and test plot#2 is identical, located at the north side. Test Plot#3 is located on the back side of the old abandoned railroad grade along the north side of the site in the forested upland near the second large drainage ditch through this area. The numbered triangles shown on Figure 2, the Field Note Sketch Map, indicate the location of each test plot. These test plots are located by approximate measurements made by John Comis Associates from known points such as property lines and corners. 5. FIELD OBSERVATIONS AND DATA EVALUATION (including Vegetation, Soils, and Hydrology). For the purpose of this investigation, three (3)test plots were sampled and recorded on field data sheets included in Appendix 1. Test plots are numbered as shown in Table 1. Findings for each test plot are summarized in Table 1. TABLE 1: RESULTS OF TRIPLE PARAMETER DETERMINATION FOR EACH TEST PLOT Test Hydrophytic Hydric Hydrology Wetland/Non Remarks Plot Vegetation Soils Present Determination #1 No No No Non-WL clearly based on veg,soil&hydrol. 2 No No No Non-WL clearly based on veg,soil&hydrol. 3 No No No Non-WL clearly based on veg,soil&hydrol. 5.a. VEGETATION: Vegetation conditions onsite, and in adjacent offsite areas to the northwest, are generally characterized as overgrown uplands dominated by introduced species of woody vines mixed with some clumps of native trees and shrubs. The non-wetland indicator specie which dominates most 4 • • of the site is Himalayan blackberry (Rubus discolor FACU). This is mixed with other dominant plants in the area which include a few big leaf maple(Acer macrophvllum FACU) along the old railroad grade, black cottonwood (Populus trichocarpa FAC), red alder(Alnus rubra FAC) and some Oregon ash (Fraxinus latifolia FACW) are scattered around the site in the overstory stratum. Scot's broom (Cvtisus scoparius NI(UPL)), Indian plumb(Oemleria cerasiformis FACU) and elderberry (Sambucus racemosa ssp. pubens FACU)are found in some parts of the site's understory plant community. A few clumps of willow(Salix sp. FACW+/_) and hardhack(Spiraea douglasii FACW, and some buttercup (Ranunculus repens FACW), are found in along the drainage ditch mixed with the dominant upland species in the non-wetland areas. There are no obligate wetland indicators found in any part of the site area. [see footnote below for abbreviations] 1* There are no endangered, threatened or sensitive plant species identified in the wetland plant ° community. There are no unusual plants identified in the wetland. This is based on observations at the site and comparison with the current publication by the Washington Department of Natural Resources titled"Endangered, Threatened and Sensitive Vascular Plants of Washington" (Jan. 1994). This publication is compiled by the Washington Natural Heritage program and updated regularly. It frequently has information which is significant to wetland categorization. The results of the onsite vegetation analysis for each test plot are summarized in Table 1. The detailed vegetation data including indicator status for each species are documented on field data sheets included with this report in Appendix 1. A description of the meaning of indicator status is included in Appendix 2. 5.b. SOILS: Soils in the study area are generally shown on the SCS Soils Survey Map as a Renton silt loam (Re)with nearly level to gently undulating topography. The slopes are 0 to 1 percent. The area also appears to have a Puyallup fine sandy loam(Py)which is a moderately well drained soil in valley bottoms with slopes of less than 2 percent. The Renton and Puyallup series are listed by the SCS as a non-hydric(upland)soil. Other soil types included within this map unit are as much as 15% Briscot and Pilchuck soils, and some poorly drained Seattle muck in depressions. Soil characteristics in the offsite area to the north where there is a constructed commercial development with a large storm water drainage system, indicates a non-hydric soil condition typical of a filled site. 5.c. HYDROLOGY: The bottom of the drainage ditches through the middle of the onsite area and along the north property line had some water saturation at this time but the soils along the banks clearly indicated a well drained, non-hydric condition exists in the site area. No seepage or groundwater infiltration was observed at this time to indicate there was any hydrology in the area sufficient to support a 1• OBL =Obligate Wetland species("almost always occurs",>99%probability) FACW=Facultative Wetland species("usually occurs" 67-99%probability) FAC =Facultative species("equally likely to occur",34-66%probabil)ty) FACU=Facultative Upland species("usually occurs in non-wetlands" 67-99%probability) UPL =Upland species("almost always occurs in non-wetlands",>99d/o probability) NI =No Indicator Assigned(If a species does not occur in wetlands in any region,it is not listed.

Furthermore, the area appears to infiltrate surface waters and the waters are drained away from the site at a sufficient rate by the drainage ditches and large culverts. [See the field note sketch map, Figure 2, for details of ditch and culvert sizes found at the site.] Drainage patterns in the surrounding offsite area are shown on the City's drainage map. There are no concentrated flows in the onsite area which would cause ponding for sufficient periods to sustain a wetland ecology outside of the maintained drainage ditches. Surface runoff from the site appears to infiltrate into the ground around the site or flows directly into the large ditch through the site and on to the west into the culverts and main drainage system west of Oaksdale Avenue SW. 6. CONCLUSIONS for Jurisdictional Determination and Rationale. The entire site is determined to be a non-wetland. The rationale for a non-wetland determination is at least 1 of the 3 parameters(hydrophytic vegetation, hydric soil, or hydrology) is not present in the test plot. The vegetation and hydric soil assessment procedures are used for the onsite non- wetland determination. Furthermore, the offsite vegetation and hydrology indictors appear to indicate that wetland conditions do not exist in the adjacent offsite area. The lack of sufficient hydrophytic vegetation appears to result from sufficiently drained subsoil's and lack of ponded surface water or groundwater saturation due to natural and man-made drainage systems in the offsite area. Soils are not saturated for sufficient periods to cause a hydromorphic soil condition to persist. This is indicated by the spread of facultative upland woody vines such as blackberries which dominate the ground cover across most of the area. Invasive and native plant species such as creeping buttercup and redtwig dogwood appear to mostly consist of intermittent core plants which would normally be expected to expand into a mat if the soils were functioning as hydric soils. The soils do not have dominant hydric soil characteristics. The large ditches through the site and offsite to the north reveals a mineral soil in the upper horizon with a dense silty sand texture, a deep root zone, and a soil color with matrix chroma of 3 or greater. All field indicators are for a non-hydric mineral soil. Hydrologic conditions do not persist within the site for sufficient periods (at least 7 consecutive days in the growing season, March thru October) and at depths(15 inches or less)to sustain a wetland ecology and a jurisdictional wetland determination. The conclusion of this analysis is that the field indicators are not present and do not produce a positive wetland determination in the study area. Furthermore, no offsite wetlands appears to be situated within 100 feet of the site boundary as indicated by an offsite inspection and review of City Wetland Inventory Maps. 6 .

M[TIIODOLOGY FOR WETLAND DETERMINATION AND DELINEATION I METHODOLOGY A. APPROACH USED FOR WETLAND DETERMINATION (MANUAL METHOD) Wetlands are identified using the 1987 Corps of Engineers Wetlands Delineation Manual (Technical Report Y-87-1, January, 1987). The preferred method used is the"ROUTINE Onsite Determination Method"for typical, generally undisturbed areas with normal environmental conditions. The selection of a specific method or procedure for identifying and delineating "jurisdictional" wetlands (i.e. scientifically defined areas based on the 3-parameters of vegetation, soils, and hydrology) may follow one of 3 methods: 1)the"routine onsite determination method"for undisturbed and non-problem area wetlands; 2)the"offsite determination method"for areas within 150'of the project boundary; and/or 3)the"disturbed area and problem area wetland determination procedures"for areas with disturbed or atypical vegetation, soils or hydrology. If an area is disturbed, then a higher level of analysis such as an "intermediate"or"comprehensive" method may be required. The onsite assessment procedure is used to determine if a jurisdictional wetland is present in the area. This method is described in the manual. The manual specifies an area must meet all three criteria to be"determined" a jurisdictional wetland: there is characteristic wetlands vegetation; the soil shows it has been water saturated in the past; and groundwater must come within 12 to r 15 inches of the surface for at least 7 consecutive days in the growing season (March thru October). If an area has no well established vegetation due to clearing or grading activities, it is called "disturbed and/or atypical". Then soils and hydrology criterion are the only field indicators used to determine if an area is to be a"jurisdictional wetland". Either the plant community assessment procedure or the hydric soil assessment procedure is used to determine if a specific test plot is a wetland or non-wetland along the boundary area. The procedure used for each test plot is indicated on the individual data sheets. The results of each sample test plot is recorded on a field data form included in APPENDIX 1. B. KEY DEFINITIONS USED For this study, wetlands are identified using a 3-parameter criteria presented in the Corps of Engineers manual (1987). If an area has sufficient vegetation, soils, and hydrology present which are indicators of a wetland, then the area is determined to be a"jurisdictional wetland". For this wetland study, "regulated"jurisdictional wetlands are defined using the adopted City of Renton Wetlands Management Regulations, City Code Chapter 32. "Wetlands are those lands transitional between terrestrial and aquatic systems that are inundated or saturated by surface water or ground water at a frequency and duration sufficient to support; and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soils conditions. For the purpose of regulation, the exact location of the wetland edge shall be determined by the wetlands specialist..." Wetlands generally include small lakes, ponds, streams, swamps, marshes, bogs, and similar areas. Regulated Wetlands do not include those artificial[jurisdictional]wetlands intentionally created from non-wetland sites, including but not limited to irrigation and drainage ditches, grass-lined swales, canals, detention facilities,wastewater treatment facilities, farm ponds, and landscape amenities if routinely maintained for those purposes. 7 However, regulated wetlands do include those artificial wetlands intentionally created to mitigate conversion of[other regulated]wetlands. C. WETLAND RATING AND REGULATION Wetlands are"rated"for regulatory purposes using the 3-tiered system specified by City of Renton's Wetland Management Regulations, Chapter 32. Each wetland is rated using the "Wetland Rating Data Forms"specified in the Washington State Department of Ecology's (WDOE) Wetlands Rating System for Western Washington, Second Edition (August 1993). The standards adopted by the City are applied to areas that are"regulated jurisdictional wetlands". Basically no regulated activities shall be permitted within a Category I wetland or it's buffer. Category II and III wetlands which are regulated may be allowed to have some alterations if the applicant can demonstrate either a) no practicable alternative; b)extraordinary hardship; or c) public interest as defined by the ordinance(13.11.240, .250, .260). For all wetlands types, the applicant must demonstrate all of the following conditions are met: a)the existence of any plant or wildlife species appearing on the federal or state endangered or threatened species list will not be jeopardized; b)the proposal will not lead to significant degradation of groundwater or surface water quality; and c)the proposal complies with the remaining standards of this chapter, including those pertaining to wetland compensation and the provision of bonds. The minimum threshold size for all wetlands is 2,200 square feet. If a wetland is hydrologically isolated, classified and identified as a Category I, II or III wetland, and has a total cumulative area of less than 2,200 square feet, regardless of property lines, then it is exempt from the provisions of this chapter(ref.: 4-32-3-C). High quality wetlands which are determined to not have exceptional value, and are a Category II wetland less than 2,200sf, the Land Use Administrator may exclude the wetland from the provisions of this chapter. Lower quality wetlands which are determined to be less than 5,000 square feet, are severely disturbed, or are newly emerging wetlands, may also be excluded from the provisions of this chapter. D. WETLAND DELINEATION For a wetland plant community delineation, we use vegetation criterion in wetland margins where hydrophytic and upland plants are transitional. Plant communities are analyzed in detail and vegetation data are documented on Field Data Sheets for individual test plot locations shown on report figures and on field note sketch maps. The specie identifications are based on available plant keys such as Hitchcock and Cronquist's Flora of the Pacific Northwest(1973). To determine whether plant species exhibit hydrophytic adaptations, if they are native or non-native (introduced), and which strata(tree, shrub, herb)they normally occupy, we use the National List of Plant Species That Occur in Wetlands: Northwest (Region 9), published by the US Fish and Wildlife Service, May 1988. The indicator status for the various species found in the area are determined based on the National List together with the December 1993 supplement for the Northwest Region. The indicator status defines the frequency of occurrence in wetlands. Indicators used are: OBL = Obligate Wetland species ("almost always occurs", >99% probability) FACW= Facultative Wetland species("usually occurs", 67-99% probability) FAC = Facultative species ("equally likely to occur', 34-66% probability) FACU = Facultative Upland species ("usually occurs in non-wetlands", 67-99% probability) UPL = Upland species ("almost always occurs in non-wetlands", >99% probability) NI = No Indicator assigned (If a species does not occur in wetlands in any region, it is not listed. Parenthesis ( )around an indicator signifies the status is assigned based on the judgment of this investigator.) +=slightly more frequently found in wetlands. 8 -= slightly less frequently found in wetlands. *= a tentative assignment of indicator status based on either limited information or conflicting reviews in the 1993 Northwest Supplement. For a wetland soil delineation, we use the hydric soil criterion prescribed in Part II of the federal manual. Hydric soils are defined as"a soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part[horizons]that favor the growth and regeneration of hydrophytic vegetation." (1985, as amended by the National Tech. Committee for Hydric Soils in December 1986) In general, this must occur in the upper 18"of the soil profile and usually for one week or more during the period when soil temperatures are above biologic zero (41°F) (Soil Taxonomy, 1975). In general, "organic hydric soils"develop as a result of prolonged anaerobic conditions with long periods of saturation impeding decomposition (peat or muck)and have greater than 16"of organic matter in the surface layer(Histosols). "Mineral hydric soils" have less than 16"of organic matter (if some, the'histic epipedon' is present), are saturated for more than 7 consecutive days during the growing season (the period when soil temperatures are above biologic zero, 41°F, as defined by"Soil Taxonomy", 1975; usually March-October), and contain dominant gleying and/or mottling. The soil color and/or presence of mottling and gleying in a sample are primary field indicators of whether a mineral soil is either hydric or non-hydric. Non-hydric soils are generally a rusty red or yellow color, while hydric soils are black, gray, or washed out in color. A hydric mineral soil must have a low chroma color feature(at least 2 or less) in the soil matrix. Gleying and mottling are color indicators of prolonged saturation and indicate that anaerobic conditions probably exist for sufficient periods of time to develop a wetland soil ecology if allowed to persist. Gleyed soils are generally gray in color. The gleying results from the leaching of the dissolved (reduced) iron and manganese minerals out of the soil column. Soils gleyed to the surface or to the surface layer of organic material are generally considered hydric. Soils that are saturated throughout the year are usually uniformly gleyed to the surface(Tiner and Veneman 1987). Mottles are generally yellow to reddish brown blotches accumulating in mineral soil due to a fluctuating water table during the growing season. The size, number and color of mottles reflects the duration of soil saturation and thus whether the soil is hydric. Mottling in hydric soils should be "distinct"or"prominent" in the upper horizon. Mineral soils that have a grayish matrix(chroma 2 or less)with mottles are hydric if the mottles are not relict mottles. Mineral soils with a predominantly brown or yellow matrix and light gray mottles are not usually hydric. 1. The National Technical Committee for Hydric Soils has developed criteria for hydric soils and a list of the Nation's hydric soils(USDA Soil Conservation Service 1987). However, because of the limitations described in the federal manual (page 12-13)for the National and State lists, the SCS also maintains lists of hydric soil map units for each county in the US. For a wetland hydrology determination,we use the presence of inundation and/or saturation for a sufficient"hydroperiod"to determine whether hydrology criterion is met. The depth to free standing water in a pit or soil probe hole must be less than 18" in wetland margins where hydric and upland soils and vegetation are transitional. Topographic elevations, encrusted detritus or debris, silt lines, hydraulic gradients or computed runoff analysis are indicators of surface inundation or soil saturation. Hydric Soils Guidebook, Washington State Department of Ecology, Pub. #90-20, July 1990. 9 After a wetland determination is made, the wetland area is analyzed to determine if it is a high quality wetland or if it has any of several irreplaceable ecological functions. The wetland is then analyzed for any significant habitat values such as area, class(es), plant species diversity, structural diversity, special habitat features, buffers, and connection to streams or other habitat areas. • E. WETLAND CLASSIFICATION Wetlands are classified by a scientific hierarchical approach using complex multi-level divisions. The classification system used for this study was developed by the US Fish and Wildlife Service titled Classification of Wetlands and Deep Water Habitats of the United States, FWS/OBS-79/31, by Cowardin, et al. (December 1979). • Palustrine wetlands (these are the only wetlands identified by this study)are classified as forested, scrub-shrub, emergent, aquatic bed, and/or open water. If more than 90%of the total wetland area is dominated by one vegetated class, then it is a"mono-class". If 10% or more of the total wetland is dominated by another class, then it is a higher value wetland. The system of divisions are based on habitats that share the influence of similar hydrology, geomorphology, chemical, or biological factors. The wetland systems involved in the project site are generally limited to"palustrine"systems, with classes and subclasses determined by dominant vegetation such as"emergenP' (EM), "scrub-shrub" (SS)and/or"forested' (FO). The class of a particular wetland describes the general appearance of the ecosystem in terms of either the dominant vegetation or the substrate type. When over 30% cover by vegetation is present, a vegetation class is used (e.g., "emergent", "scrub-shrub"and/or"forested'). When less than 30%of the substrate is covered by vegetation, then a substrate class is used (e.g., "unconsolidated bottom", "aquatic bed', or"moss-lichen"). Typical demarcations of these classes of palustrine systems are shown in the Cowardin report.
