Box 330310 Seattle, WA 98133-9710 SUBJECT: SR-167 CULVERT IMPROVEMENTS REVISED PROPOSAL FOR THE PANTHER CREEK CULVERTS Dear Ms. Suafoa: Thank you for meeting with me February 12, 1998,to discuss the City's proposal to close the SR- 167 culvert at Sta 1071+00(24" culvert) and install a restrictor on the culvert at Sta 1076+00 as it relates to the pending SR-167 Stage 3 project. While there were no concerns with installing a restrictor on the 30" culvert, Stage 3 staff were concerned that closing the 24" culvert this summer would make it more difficult for the Stage 3 project to get the necessary permits to then relocate the ditch between the 24" and 30" culverts. The ditch on the east side of SR-167 between the 24" and 30" culverts needs to be moved to the east out of the way of the proposed ramp widening planned under Stage 3. Closing the 24" culvert would mean that Panther Creek would be diverted into the section of ditch that must be moved. To try and address the Stage 3 issues, we identified three options to pursue with WDFW regarding the 24" and 30" culverts. I. Continue with the current proposal to close the 24" culvert and install a restrictor on the 30" culvert, but seek to defer the creek habitat enhancements that would be required by WDFW until the channel on the east side of SR-167 could be moved to the east by the Stage 3 project or a separate project action. According to Phil Schneider of WDFW, habitat enhancements to the relocated creek would be required as a condition of the HPA permit if the 24"culvert is closed. 2. install a restrictor on the 30" culvert and partially restrict the 24" culvert as much as WDFW will allow while not requiring creek habitat enhancements and not changing what is considered to be"the creek." 3. Defer closing the 24" culvert and installing a restrictor on the 30" culvert until the channel on the east side of SR-167 could be moved to the east by the Stage 3 project or a separate project action. Since the City's East Side Green River Watershed Project environmental impact statement (EIS) did not include relocating the creek, a new SEPA determination would be needed under the Stage 3 project or a separate project. A separate JARPA application would also have to be submitted to state agencies and the Corps of Engineers to obtain the necessary state and federal permits. Finally, WSDOT does not have any funds available at this time to pursue relocation of the creek. As we agreed, I discussed the above options with Phil Schneider of WDFW. Phil said that he would permit relocating and enhancing the creek, as well as the proposed culvert modifications as 200 Mill Avenue South - Renton, Washington 98055 9 This paper contains 50%recycled material,20%post consumer Rumina Suafoa Revised Proposal for the Panther Creek Culverts Page 2 a combined project, but would not support deferring the habitat enhancements. Phil also didn't want to make any partial changes to the 24" culvert as proposed under Option 2 above. He noted that a separate JARPA and SEPA review would be needed to move the creek. Since deferral is not possible and it does not make any sense to perform enhancements now to only have remove them when the ditch is moved by the Stage 3 project, our only recourse is to defer our plans to close the 24" culvert as proposed in Option 3 above. However, contrary to as stated in Option 3, we want to continue with our plans to install a restrictor on the 30" culvert. Phil Schneider indicated that he would permit installing the restrictor if the"overflow channel" were constructed as proposed in our original JARPA application for the SR-167 culvert modifications. We are very concerned about the delay in the closure of the 24" culvert because of the flooding currently occurring in the downstream system that was not designed to handle the flows from the 24" and 30" culverts across SR-167. With a restrictor on the 30" culvert, we will partially achieve our flood protection goals while not complicating the permitting of the SR-167 Stage 3 project. However, we wish to work with WSDOT to continue to move forward toward closure of the 24"culvert. I am personally of the opinion that the Stage 3 project will need to close the 24" culvert in order to have enough room to site the water quality facilities needed for Stage 3. It seems that it would be in WSDOT's best interest to pursue closure of the 24"culvert and relocation of the creek as soon as possible, so that the relocation does not end up controlling the Stage 3 project schedule. It is also important to the City that WSDOT secure funding for the creek relocation as soon as possible so that the delay in closure of the 24"culvert is kept to a minimum. Since we will be processing a local agency agreement for the 72" culvert at SW 23rd Street, we should also formalize the responsibilities of WSDOT and the City with respect to the 24" culvert and creek relocation within that agreement. Since relocation of the creek is needed to accommodate the Stage 3 project, the City's responsibility should be limited to closure of the 24" culvert and whatever enhancement of the creek would have been required by WDFW as a condition of the culvert closure. We would also allow WSDOT to use adjacent City property for the creek relocation at no cost if additional space outside of the existing SR-167 right-of-way is needed. We should receive our HPA from WDFW within the next two weeks for the work original proposed in our JARPA application, minus closure of the 24" culvert. I will forward a copy to you as soon as I have received the permit. If you have any questions, please contact me at 425-277-5547.

The initial comments from Phil were that the ditch would be considered a creek from the point the creek entered the roadside ditch. This distance measured 50 feet to the south of the cross culvert at Station 1071+00. After a discussion about the merit of plugging the culvert and forcing the creek to continue north in the ditch, Phil commented that the ditch would now be considered part of Panther creek. In order to route most of the existing flows from Panther creek to Station 1076+00, the creek bed would have to be enhanced. Laura explained the need for plugging the culvert at Station 1071+00 to separate the creek from ramp runoff. There was talk of an interim solution between the culvert construction and Stage 3 projects. There was talk about not completely closing the 24"culvert but instead placing a restriction in the 24" diameter cross culvert. There was talk of placing additional pipe onto the 24" culvert and berming off the Panther Creek to force it to runoff into the wetland. The conclusion of this discussion was that there would be permit involvement with the Corps and Fisheries to do anything major with the Panther creek. The existing Corps permit does not allow any excavation or embankment for berming in the area of Station 1071+00. As we moved down to the 30" culvert at Sta 1076+00, Mike made a case that plugging the culvert at 1071+00 would create 500 more feet of creek on the east side of SR 167. This would result in making it more difficult for the Stage 3 project to get a permit from the Corps and Fisheries to move the ditch. It would be preferable if the existing and any additional creek would have to be relocated behind a berm to keep Panther creek from following the edge of the roadway. Again, any additional work beyond what is approved to do by the Corps permit, will have to be revisited with the Corps. R Record of Meeting February 5, 1998 Page 2 Scott Woodbury had one final comments: If the culvert cannot be plugged, due to additional costs for the project or additional time needed for another Corps permit to move the creek, then the culvert construction project at SW 23 d Street will still happen. However, the culvert at 1076+00 may have the flow restriction placed in it. It was agreed to have a discussion in-house about a bio-engineered channel within the Panther Creek wetland to permanently move the creek. Moving the Panther Creek would need to be a joint effort of WSDOT, the City of Renton, DOE, COE and DFW to address the needs of all interested parties. Action Required: A meeting will be scheduled next week on Thursday, February 12, 1998 to discuss further the fate of Panther Creek and wetland impacts, mitigation, etc. Ms m V>",) yjl� 14 p 5 p, s� / Sy /� z Tom"✓ 1ra� arn/ '1 —► >N .� �+?r•� rl* --wow ,W65m P, �"�� Shee11 Z J,z 1qv BID ITEM TOTAL I UNIT PRICE STD.ITE BID ITEMS PROJECT ALTERI6ATPAEI ALTERNATIVE2 AGREEMENTWITH NO, QUPlO1TY NO, UNIT AMOUNT OPEN 6CU PIFERAMMING CITYOFRENTON PREPARATION 1 ILUMPSUMIS 50.000.00 1 0001 EST.

The initial comments from Phil were that the ditch would be considered a creek from the point the creek entered the roadside ditch. This distance measured 50 feet to the south of the cross culvert at Station 1071+00. After a discussion about the merit of plugging the culvert and forcing the creek to continue north in the ditch, Phil commented that the ditch would now be considered part of Panther creek. In order to route most of the existing flows from Panther creek to Station 1076+00, the creek bed would have to be enhanced. Laura explained the need for plugging the culvert c-+ St- to separate the creek from ramp runoff. 10-7 a) Suite-e� !r< c...•�G,�ely CAS"7 ( LY�ctr/wif, �w'r iM5?aw.� i/A4w� AThere was talk of an interimon between the culvert construction and Stage 3 projects. There was talk ab restriction in the 24"diameter cross culvert. There was talk of placing additional pipe onto the 24" culvert and berming off the Panther Creek to force it to runoff into the wetland. The conclusion of this discussion was that there would be permit involvement with the Corps and Fisheries to do anything major with the Panther creek. The existing Corps permit does not allow any excavation or embankment for berming in the area of Station 1071+00. As we moved down to the 30" culvert at Sta 1076+00, Mike made acaase that d u� plugging the culvert at 1071+0 , would create 500 more feet of creek. s would {o result in making it more difficult for the Stage 3 project get a permit from the Corpil; ".0 ftr-ff, , it The existing and any additional creek watT}d-ha tee relocated behind a berm to keep Panther creek from following the edge of the roadway. Again, any additional work u. ASS beyond what is approved to do by the Corps permit, will have to be revisited with the Corps.

Enclosed is the following flow and elevation information you requested for the SR-167 project: • projected flows at the proposed SR-167 culvert at SW 23rd Street with the proposed flood control weir in place (see Attachment 1). See also sheet 11 of 14 of the SR-167 DARPA application for details of the proposed flood control weir. • projected flows at the proposed SR-167 culvert at SW 23rd Street with the proposed flood control weir removed(see Attachment 2). The remainder of the letter is written in a question and answer format to hopefully more clearly address any remaining concerns you may have regarding the proposed SR-167 culvert design. 1. How were the flows and elevations determined? The flows and elevations in Attachments 1 and 2 were produced from the City's watershed models. Section 6.5 of the East Side Green River Watershed Project Final Plan dated September 1997 transmitted to you previously gives an overview of the watershed models and modeling approach. 2. What is the elevation of the existing ditch downstream of East Valley Road? The approximate grade of the bottom of the existing ditch downstream of East Valley Road is shown in the attached 11"x17" Schematic Plan and Profile. The drawing shows the existing culverts at Lind Avenue and East Valley Road and the proposed culverts at SR-167 and the Olympic Pipe Line crossing just west of Lind Avenue. To facilitate your review, I added the flow and elevation data from Attachment 2 to the profile that assumes no deepening of the SW 23rd Street channel. The existing grade of the channel in the 11"xl7" Schematic Plan and Profile is based on a 1989 survey. A drawing of a portion of the 1989 survey in the vicinity of East Valley Road and SR- 167 is included as Attachment 3. 3. What is the elevation of the existing East Valley Road culverts and proposed SR- 167 culvert? According to the 1989 survey, the existing East Valley Road culverts have an outlet elevation of about 5.9 feet and an inlet elevation of about 6.3 feet. The proposed SR-167 culvert will have an outlet elevation of 7.0 feet and an inlet elevation of 7.3 feet. The inlet elevation of 7.3 feet is 0.35-foot lower than that shown in the JARPA application. The slightly lower elevation is needed so the flow velocity does not exceed 3-feet per second for the 2-year event as discussed in Question 5 below. Phil Schneider SR-167 Culvert Modification Project Page 2 4. Will the SR-167 culvert as proposed be fish passable even under low flow conditions? Under existing downstream conditions, the existing E. Valley Road culverts are at least 2 feet below the level of the highest point in the downstream ditch. The proposed SR-167 culvert will be at least 1.2 feet below the highest point of the downstream ditch. If upstream fish passage through the culvert is allowed in the future, this partially submerged condition would facilitate fish passage during low flow periods. The 7.0 feet outlet elevation of the SR-167 culvert provides a depth of submergence during low flow conditions of about 1.5 feet deep or about 25%of the proposed 6-foot diameter culvert. The Panther Creek Wetland is expected to settle and filter most of the sediment loading inputs to the wetland before flows reach the culvert. Any sediments reaching the culvert would be very fine grained and would likely be scoured downstream out of the culvert during flood events. Therefore, essentially no maintenance would be required to keep a pool of standing water in the culvert for fish passage at low flows. In our meeting you expressed concern regarding the function of the culvert for fish passage if the downstream ditch were deepened as proposed in Alternative 23ST3-3 of the East Side Green River Watershed Project (ESGRWP) Plan and EIS. The deepening of the channel would eliminate the partial submergence of the East Valley Road and SR-167 culverts unless measures were taken to maintain some submergence. This could be accomplished by replacing one of the East Valley Road culverts with a deeper culvert and installing a properly designed, fish passable weir or series of weirs near the downstream end of the SR-167 culvert. An alternative would be to use fish passable weirs at both the East Valley Road and SR-167 culverts to retain a partially submerged condition in the culverts for fish passage. Considering the other $15,000,000 of improvements identified in the East Side Green River Watershed Project Final Plan, and the fact that our federal funding sponsor is telling us that we will not have their financial assistance for 5 to 10 years, the potential for implementing the channel deepening is very remote. We may still want to deepen the channel between Springbrook Creek and Lind Avenue, but it is very unlikely that we will pursue deepening of the reach of the channel between Lind Avenue and East Valley Road. It is this reach of the channel that controls the water elevations through the East Valley Road and SR-167 culverts. Given our reservations with the channel deepening, we wish to avoid having to design the SR-167 culvert for a potential condition that will likely never exist. 5. What is the projected velocity through the proposed SR-167 culvert, assuming the flood control weir is removed? Assuming the downstream channel from Lind Avenue to East Valley Road is not deepened, the projected velocity of flow through the culvert may be calculated using the flow and elevation data listed in Attachment 2. The velocities are as follows: • 2-year current event: 3.0 feet per second(Q=74 cfs, d=4.9 feet) • 2-year future event: 3.0 feet per second(Q=75 cfs, d=5.0 feet) • 25-year future event: 3.9 feet per second(Q=109 cfs,d=6.0 feet or full flow) • 100-year future event: 4.6 feet per second(Q=129, cfs, full flow) Note: Q is the flow and d is the depth of flow. Because little sediment accumulations are expected as discussed in Question 4 above, all of the culvert is considered effective for conveying flows. Phil Schneider SR-167 Culvert Modification Project Page 3 If the downstream channel were deepened, the velocity for the 2-year current flow event would be as high as 5.8 feet per second. Thus the downstream channel could not be deepened without installing some outlet control on the culverts to maintain sufficient flow depths to keep the 2- year event velocity at 3 feet per second. The outlet control could be accomplished using fish passable weirs as discussed in Question 4 above. However, it is very unlikely that we will pursue deepening of the SW 23rd Street drainage channel between Lind Avenue and East Valley Road(see last paragraph of Question 4). 6. What effect would removal of the flood control weir have on the Panther Creek Wetland upstream of the culvert and on the downstream channel? The effect of removing the flood control weir is shown in the following summary table: Compare flows and elevations with and without the flood control weir in place Assumes that the SW 23rd Street channel from E.Valley Road to Lind Ave is not deepened w/flood control weir w/o flood control weir Flow(cfs) Elev(ft) Flow(cfs) Elev(ft) 2-yr current 33 14.1 74 12.3 At SR-167 2-yrfuture 35 14.1 75 12.3 culvert inlet 25-yr future 86 15.5 109 13.7 100-yrfuture 107 16.1 129 14.8 2-yr current 41 10.9 90 11.6 At E. Valley Rd. 2-yr future 56 11.1 102 11.6 culvert outlet 25-yr future 113 12 132 12.3 100-yrfuture 159 12.7 172 12.8 Note: The data for the above table were taken from Attachments 1 and 2. Flows would more than double for the 2-year event if the flood control weir were removed. The percentage increase in flows due to removal of the flood control weir is less for the more severe events. It is important to clarify that total removal of the inlet control on the SR-167 culvert would likely not be allowed because of wetland impact concerns associated with lowering normal water levels in the wetland. Therefore, while the flood control portion of the inlet control weir may be removed in the future, continued control of wetland water levels will likely be necessary. 7. What modifications will be needed in the future if upstream fish migration through the SR-167 culvert is to be allowed? Because the invert elevation of the proposed culvert's inlet is about 3 feet below the proposed low flow outlet from the wetland and about 5 feet below the normal winter water level of the wetland, a fish ladder and/or other suitable fishway device would need to be constructed upstream of the culvert's inlet to allow fish into the wetland and still maintain normal wetland water levels. 8. Is the culvert deep enough to allow a channel to be constructed upstream through the wetland? The proposed culvert is about 3 feet below the approximate grade of the wetland so a channel could be constructed upstream of the culvert through the wetland to the Panther Creek ravine near Valley Medical Center, should changes in wetland or fisheries regulations allow such a channel. Phil Schneider SR-167 Culvert Modification Project Page 4 In summary we feel that the design proposed in the JARPA application, with the slightly lower inlet elevation of 7.3 feet, will work for fish passage with the existing downstream SW 23rd Street channel. Again, as discussed above, it is very unlikely that we will pursue deepening of the SW 23rd Street drainage channel between Lind Avenue and East Valley Road. I will forward updated design plans to you once they are available from WSDOT. We hope the information discussed in this letter addresses your concerns and will allow you to issue an HPA for the SR-167 Culvert Modification Project once you have received the updated design plans.

Enclosed is the following information you requested for the SR-167 project: • 1989 survey of the ditch downstream of East Valley Road(EVR); • projected flows at the proposed SR-167 culvert at SW 23rd Street(Table 8-2 of the East Side Green River Watershed Project Plan and EIS) I have also enclosed recently collected ground and surface water mo 'toring data along the SW 23rd Street drainage channel for your review. i The enclosed 1989 survey shows the highest elevation in the itch downstream of EVR to be 8.9 feet (NGVD 1929). The enclosed surface water moni data indicates that the highest �O elevation in the ditch downstream of EVR to be about 8.5 eet as I mentioned to you in our meeting. The difference in elevations could likely be d to the fact that different benchmarks were used to tie the 1989 survey and the recently installed water monitoring gages to the NGVD 1929 datum. It is important to note that the surface water monitoring data for 7/25/97, 8/5/97, and 9/5/97 shows that the water level at the downstream end of the EVR cross culverts had dropped below the level of the downstream ditch. This is supported by the fact that there was no flow from the Panther Creek Wetland into the ditch on 8/5/97 and 9/5/97. The trickle of water observed flowing from the wetland on 7/25/97 is believed to have infiltrated and/or evapo-transpirated in the pool at the outlet of the EVR culverts instead of producing any flow into the downstream ditch. No direct observation of the flow in the ditch immediately downstream of the pool was made. Using the enclosed downstream survey information and flow information from the City's watershed models, I wish to make the following observations regarding the suitability of the proposed design for future fish passage: 1. The SR-167 culvert would be fish passable even under low flow conditions. Under existing downstream conditions, the existing EVR culverts are at least 2 feet below the level of the highest point in the downstream ditch. The proposed SR-167 culvert is at least 0.85 feet below the highest point of the downstream ditch. If in the future the proposed inlet control structure on the SR-167 culvert were removed, this partially submerged condition would facilitate fish passage during low flow periods. Phil Schneider SR-167 Culvert Modification Project Page 2 The Panther Creek Wetland is expected to settle and filter most of the sediment loading inputs to the wetland before flows reach the culvert. Any sediments reaching the culvert would be very fine grained and would likely be scoured downstream out of the culvert during flood events. Therefore,essentially no maintenance would be required to keep a pool of standing water in the culvert for fish passage at low flows. If necessary, the SR-167 culvert slope could be flattened slightly to increase the depth of standing water at the upstream end of the culvert, but we wish to avoid deepening the downstream end any further below the elevation 7.0 feet proposed in the JARPA application. At the 7.0 feet elevation the depth of submergence during low flow conditions would be about 1.5 feet deep or about 25%of the proposed 6-foot diameter culvert. In our meeting you expressed concern regarding the function of the culvert for fish passage if the downstream ditch were deepened as proposed in Alternative 23ST3-3 of the East Side Green River Watershed Project (ESGRWP) Plan and EIS. A conceptual profile of the channel deepening is shown in the attached copy of Figure 8-8 of the ESGRWP Plan. The deepening of the channel would eliminate the partial submergence of the EVR and SR-167 culverts. However,we realize that some submergence would be required to comply with fish passage criteria. This could be accomplished by replacing one of the EVR culverts with a deeper culvert and installing a properly designed, fish passable weir or series of weirs near the downstream end of the SR-167 culvert. An alternative would be to use fish passable weirs at both the EVR and SR-167 culverts to retain a partially submerged condition in the culverts for fish passage. 2. The SR-167 culvert will meet fish passage velocity criteria with the inlet control weir removed. Attached is a copy of Table 8-2 from the ESGRWP Plan. Peak flows through the proposed SR-167 culvert assuming no inlet control weir and the existing downstream SW 23rd Street drainage channel can be conservatively approximated from Table 8-2 by adding the flows into the wetland from Panther and Rolling Hills Creeks and subtracting the outflow from the existing northern outlet from the wetland. The velocity of flow through the culvert can be obtained by dividing the calculated flow by the area of flow within the culvert. The results are summarized for the preferred ESGRWP alternative in the following Table 1. Table 1 -Approximation of flow (cfs)and velocity(fps)through the proposed SR-167 culvert assuming 6-foot diameter culvert and no inlet control weir Panther Creek Rolling Hills Creek SR-167 Flow at Proposed Velocity at u/s of SR-167 u/s 132"culvert North Outlet SR-167 Culvert Proposed SR-167 (a) (b) (c) (d=a+b-c) Culvert 2-yr current event 61 68 39 90 3.91 2-yr future event 62 69 40 91 3.8' 25-yr future event 96 103 66 133 4.7 100-yr future event 167 173 88 252 8.9 'Tailwater and flow conditions are such that the pipe is not flowing full. Phil Schneider SR-167 Culvert Modification Project Page 3 The calculated flows listed in Table I are much higher than the flows listed in Table 8-2 that are projected to pass through the proposed SR-167 culvert if an inlet control weir is used. Table 8-2 of the ESGRWP Plan lists the 2-year future land use event flow through the SR- 167 culvert with an inlet control structure as 35 cfs. Flows through the culvert without the inlet control structure can be twice this amount, or about 70 cfs, before the velocity of flow through the culvert would exceed 3 feet per second. Because the Panther Creek Wetland would still provide some flood storage and flow attenuation even if no inlet control weir is used, flows through the culvert without the weir are expected to be closer to 70 cfs, rather than the 90 or 91 cfs listed in Table 1 above for the 2-year event. In summary we feel that the design proposed in the JARPA application will work for fish passage should the downstream SW 23rd Street channel not be deepened in the future. We also feel that the design would work if the downstream channel were deepened, provided measures are taken in the future to maintain a partial submergence of the culverts as discussed above. We hope this information addresses your concerns and will allow you to issue an HPA for the SR-167 Culvert Modification Project. Please contact me at 425-277-5547 if additional information is needed or if you have any other questions.

Engifleering uept. P.O. Box 1800 Renton, WA 98057 RE: SR 167 Culvert Construction and Drainage Improvements Dear Mr. Burnett: Thank you for your Dec. 19, 1997 letter concerning the stabilization of the soils in the vicinity of your pipe lines. It is highly unlikely that erosion will occur in this vicinity as a result of the proposed wetland improvements for a number of reasons. First,the designed flows through the ditch near your lines will typically be under 2 ft./sec. and no greater than 3 ft./sec.. Second, at approximately 30 ft. from the edge of the ditch,your lines will be a comfortable distance from the wetland flows. Third, as an extra soil stabilization measure vegetation will be established along the sides of the ditch. Enclosed please find a record of our December 17, 1997 meeting with Mr. Mark Kruger of your company. We will send you a Construction Permit for your review and signature in the coming weeks. We plan to advertise this project to bidders in April, 1998,and construction is scheduled to begin in June, 1998. Please call me with your questions or comments at any time at(206)440-4560. Sincerely, a" David Schor Transportation Engineer Project Development Cc: Scott Woodbury,City of Renton Project File Enclosures: Meeting Minutes s A...\o12836VmernosVoplco-t.doc , Meeting Minutes Proj. #OL 2836 WSDOT and Olympic Pipe Line Co. December 17, 1997 Project Site: SR 167 & East Valley Rd. at SW 23rd St. Attendees: Mark K. Kruger, Operations Specialist 206/682-1211 -- Olympic Pipe Line Co. David Schor, Transportation Engineer —Washington State Dept. of Transportation 206/440 4560 Cheri McLeod, Engineering Technician --Washington State Dept. of Transportation 2061440-4559 Subject: SR 167 Culvert Construction, Utility Coordination DISCUSSION: 1. Mr. Schor described the SR 167 culvert construction and ditch realignment work planned in the vicinity of Sta. 1120+75 (SW 23rd St.). The ditch realignment will come within 30 feet of the Olympic Pipe Line (OPL) lines, and the new cross culvert will come within 50 feet. Construction staging activity may require vehicles to be over the OPL lines during the construction period (June - Nov., 1998). Mr. Schor gave a copy of the latest drainage plan drawings to Mr. Kruger. Mr. Schor asked Mr. Kruger to discuss OPL's concerns and pipe line protection requirements. 2. Mr. Kruger expressed the following OPL concerns: That the DOT avoid operating or parking any vehicles over OPL lines. Mr. Kruger offered OPL's paved access road (SW 23rd St.) as a staging and parking area, and to provide the access gate key. If DOT vehicles must operate or park over OPL lines, then OPL must be given sufficient notice to schedule a representative to be on site. In this event, OPL will also require either sufficient extra cover, plates, or platforms to safely distribute vehicle loads and protect their lines. That the DOT not change/add engine oil/fuel on OPL property. And that the DOT clean up and restore OPL property following construction. 3. Mr. Schor asked that OPL grant the DOT a Construction Permit (a signed statement to be prepared) allowing the DOT to perform the construction activity on OPL property. The permit would outline OPL's restrictions, as discussed today, and as further developed. 4. Mr. Kruger offered Bob Burnette (425) 235-7767 as OPL's contact person for Construction Permits and other real estate agreements. Mr. Kruger also clarified the location of OPL's lines east of SR 167. That is, of the two lines crossing SR 167 E-W, the southern crossing is the 20" line and it turns northward east of SR 167. The northern crossing is the 16" line, and it continues eastward east of SR 167. DECISIONS MADE: 1. Mr. Schor will have a Construction Permit drafted and forwarded to OPL for review and signing. 2. OPL (either Mr. Kruger or Mr. Burnette) will provide more specific details on pipe protection requirements as the need in this case becomes clear. 3. Mr. Schor will update the plans with the location of OPL's lines.

Project Manager Surface Water Utility City of Renton 200 Mill Avenue South Renton, WA 98055 RE: SR 167 Culvert Construction JARPA Application Dear Mr. Woodbury: Thank you for providing us with your December 16, 1997 draft JARPA application for review. Attached are revised drawings. We have incorporated your notes and revisions, as well as some revisions of our own. We have the following comments on the text of the application: 1. Item 10 - Reference the proposed culvert and control structure at Sta. L1120+75. 2. Item 11a. - The project scope indicates the culvert at Sta. L1070+52 is to remain open. If it this culvert should be plugged, approximately 2 cubic yards of gravel borrow will be used. 3. Item 12b. - A total of approximately 15 cubic yards of gravel borrow will be used to plug these culverts. We also have the following comments on the drawings: 1. Please submit design calculations for sizing the 10 in. diam. opening in the flow control structure at Sta. 1076. 2. Will mowing alone, and not channel excavation, create an overflow channel to direct water from the 30"culvert at Sta. 1076 to Wetland W-4? SR 167 Culvert Construction 2 JARPA Application 12/30/97 3. Per our conversation on Dec. 22, 1997, some of your proposed revisions to the Sta. 1120+75 Adjustable Control Structure, i.e. positioning of plate cover openings, internal T-column supports, are pending further review, and are not critical to the JARPA. 4. The drainage channel geometry at the Wetland Mitigation Area, Sta. 1120+75 L, has been straightened. 5. We left the sheet references blank on the MicroStation drawings to allow you to arrange the sheets in the JARPA. Your comments on the Biology/Wetland Report have included. The revised report is attached. If you have any questions or comments,please contact me at(206) 440-4569, or David Schor at(206)440-4560.

Will fill material be placed waterward of OHWM or L? Yes. ' a. Freshwaters -volume: Z•D About 5 feet of the existing er Creek culvert at SR-167 Station L1070+52 will be removed and a plug of abo cubic yacd�uf cuaaete will be placed inside the end of the remaining pipe(see Figure 1,VV N b. Tidal waters-volume: None. 12. Will material be placed in wetlands? Yes. About 840 sq. ft. of Wetland W-4 will be temporarily disturbed for the culvert plug work at the SR-167 stations listed in Section 12b below and then restored. For the new culvert at SW 23rd Street, approximately 300 sq, ft. of Wetland W4 and 100 sq. ft. of Wetland W48e will be filled by the culvert and riprap placement. Another 1600 sq. ft. will be temporarily disturbed by the construction activity and then restored. a. Has delineation been completed? Yes. See attached report by WSDOT dated July 1994. The wetland boundaries defined in the report are still valid. See Figure 3 for a map of wetlands in the project vicinity, including the City of Renton wetland inventory number and WSDOT designation where applicable. b. Type and composition' fd atestia A total of approximately, cubic yards of to will be used to plug the following' 1, 7 existing culvert inlets on east side of SR-167 at Wetland W-4, taking care to prevent ��,J concrete from entering adjacent waters outside of the work limits: �,;> Station L 1081+90(see Figure 5) Station L 1083+95 (see Figure 5) Station L1086+15 (see Figure 5) Station L1091+75 (see Figure 6).

Material source: Local suppliers. d. List all soil series located at the project site and indicate if hydric (county): • Puget silty clay loam (Hydric) • Seattle muck (Hydric) • Tukwila muck (Hydric) • Urban land 12/16/97 Draft conditions are suitable) on each side of the mowed path to provide cover and habitat diversity. • Design the proposed SR-167 culvert at SW 23rd Street so as to not preclude fish ? passage into the Panther Creek Wetland in the future. Implementation of these elements is designed to continue to allow downstream migration of fish in the Panther Creek system while improving the potential for restoring upstream fish passage to Panther Creek in the future(SR-167 is the first of several upstream fish migration barriers on Panther Creek). The project reduces downstream flooding problems and the related impacts while providing a reliable outlet from the Panther Creek Wetland that may be easily accessed and maintained. The project is also designed to maintain and even improve the function of the affected wetland system. Impacts and Mitigation Measures: The impacts of the proposed activities and related mitigation measures are analyzed in detail in the ESGRWP Draft EIS (December 1996) and Final EIS (September 1997) under Alternatives PC2 - Element 1 and 23 ST3 Element 1. The attached EIS Mitigation Document (September 1997) presents the preferred alternative and mitigation measures adopted by the City of Renton for the ESGRWP at the conclusion of the EIS process. Refer to Alternatives PC2 -Element 1 and 23ST3 Element 1 in Tables 1 through 10 of the Mitigation Document for a summary of the impacts and mitigation measures identified for the activities proposed under in this application. 9. Proposed Starting Date: June 1998 Estimated duration of activity: 2-3 months Will project be conducted in stages?: Possibly. Individual elements of the project may be constructed sequentially or simulanteously 10. Will any structures be placed: a. waterward of the OHWM? Yes. A control structure will be placed on the existing Panther Creek culvert at SR-167 Station L 1075+95 a few feet downstream of the inlet(see Figure 5). b. waterward of MHWL in tidal waters?

Proposed Activities Under this application the City of Renton proposes to implement the following elements defined in the East Side Green River Watershed Project(ESGRWP)Final Plan and EIS(City of Renton,Sept. 1997). In summary the activities proposed include: • Alternative Element 23ST3-1. Close several poorly functioning culverts across SR-167 and replace them with a new SR-167 culvert crossing at SW 23rd Street. A control structure will be installed on the inlet to the culvert to maintain the hydrology of the Panther Creek Weiland. An approximately 110 foot outlet channel would be constructed ftom the new SR-167 culvert to connect to existing culverts under East Valley Road. • Altermative Element PC2-1. Close one of two SR-167 culverts that Panther Creek currently flows through and install a structure on the other culvert near SW 39th Street that allows low flows to pass into the existing system. Excess flows would be diverted into the Panther Creek Wetland, increasing the frequency of overflow into the wetland that already occurs under existing conditions(Element PC2-I). • Create an overflow"channel'from the Panther Creek SR-167 cross culvert to the nearest standing water in the Panther Creek Wetland by mowing/cutting a path through the existing reed canarygrass and planting willows and cottonwoods(where conditions are suitable)on each side of the mowed path to provide cover and habitat diversity. • Design the proposed SR-167 culvert at SW 23rd Street so as to not preclude fish passage into the Panther Creek Wetland in the future. Implementation of these elements is designed to continue to allow downstream migration of fish in the Panther Creek system while improving the potential for restoring upstream fish passage to Panther Creek in the future(SR- 167 is the first of several upstream fish migration barriers on Panther Creek). The project reduces downstream flooding problems and the related impacts while providing a reliable outlet from the Panther Creek Wetland that may be easily accessed and maintained. The project is also designed to maintain and even improve the overall function of the affected wetland system. B. Impacts of the Proposed Activities The ESGRWP EIS Mitigation Document(September 1997)presents the preferred alternative and mitigation measures adopted by the City of Renton for the ESGRWP at the conclusion of the EIS process. A detailed summary of the impacts and mitigation measures identified for the activities proposed under in this application are included in Tables 1 through 10 of the EIS Mitigation Document under Alternatives PC2-Element 1 and 23ST3 Element 1. A copy of the Mitigation Document may be obtained by contacting Scott Woodbury of the City of Renton at 425-277- 5547. About 2440 sq. ft. of palustrine wetlands will be temporarily disturbed by construction activities and then restored. Approximately 300 sq. ft. of Renton inventory Wetland W4 and 100 sq. ft. of Wetland W418e will be filled by the culvert installation and riprap placement under the proposed SW 23rd Street culvert crossing of SR-167. C. Mitigation Plan Wetland W-4 is a Category I wetland and W-48e is a Category 3 wetland under the City of Renton Wetlands Management Ordinance. A total of approximately 1250 sq. ft. of wetlands will be created adjacent to the outlet of the proposed culvert at SW 23rd Street to mitigate for the wetland impacts in accordance with the City of Renton regulations(see Figures 10 and 1.4). 13 zx-x-XXXU SR-167 Culvert Modifications 12/16/97 Draft IN: Wetlands Adjacent to Panther Ck./Tributary to Springbrook Ck.

Several culverts connect Wetlandanther Creek Wetland. Prominant vegetation consists of soft rush (Juncus effusus), cattail, reed canary grass, yellow iris, red osier (Cornus stolonifera), hardback, Pacific willow (Salix lasiandra), Sitka willow (Salix Sitchensis), and black cottonwood. Wetlands are discussed separately in the following section of this report. Appendix B provides definitions for wetland plant indicator status categories. Appendix C provides an alphabetical list of site plants mentioned in this report. Appendix D contains the data sheets and Appendix E is the wetland and buffer functional assessment. WETLANDS Wetland Description Wetlands are transitional areas between upland and non-vegetated aquatic environments. They are defined as those areas that are inundated or saturated by surface 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 soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas (Environmental Laboratory, 1987), Existing Conditions Observations of existing conditions and interpretations were made within the context of the 1987 Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987) and rated using the City of Renton wetland rating system. 84th Ave S. to S.

Sediment/toxicant retention is the process by which suspended solids and chemical contaminants are retained and deposited within a wetland. Additional functions include flood storage, water purification, food chain support, wildlife habitat, and education/recreation opportunities. Impacts 1U 'N A total of 4600 square feet (0.11 acre) of wetlands will be impacted as a result of the construction of the box culvert1�q d c ku eA Potential impacts can be minimized by use of the following measures: 1. Restricting clearing and grubbing activities to the maximum extent possible. 2. Use of effective erosion control techniques during construction. 3. Replacing wetland acreage and functions lost due to project construction. Mitigation 841h Ave S. to S. Grady Way 12/l511997 5 All potential adverse impacts must be addressed, and mitigation measures should include, but not be limited to, the following: . Storm Water Discharge: Applicable Best Management Practices from the Stormwater Management Manual for the Puget Sound Basin will be applied to erosion control and water treatment provisions. . Receiving Waters: Extreme caution should be exercised to avoid construction related siltation and turbidity to downstream resources, including Panther Creek. . Wetlands: The wetland is protected under Presidential Executive Order 11990, "Protection of Wetlands," Governor's Executive Orders EO 89-10 and EO 90-04, "Protection of Wetlands", and WSDOT Directives 22-27 and 31-12 (HR). These orders and directives require the use of all practicable measures to avoid impact and provide mitigation for any unavoidable impacts. The executive orders stipulate that all state agencies shall use the following definition of mitigation,and in the following order of preference: 1) Avoiding the impact altogether by not taking a certain action or part of an action; 2) Minimizing impacts by limiting the degree or magnitude of the action and its implementation by using appropriate technology or by taking affirmative steps to avoid or reduce impacts. 3) Rectifying the impacts by repairing, rehabilitation or restoring the affected environment; 4) Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action; 5) Compensating for the impact by replacing, enhancing, or providing substitute resources or environments; 6) Monitoring the impact and taking appropriate corrective measures. Mitigation for individual actions may include a combination of the above measures. 841h Ave S. to S.

Describe current use of the property, including structures: The proposed activities are located primarily within SR-167 right-of-way. For descriptions of the affected water bodies, please refer to the following sections of the East Side Green River Watershed Project (ESGRWP) Draft Plan and EIS (Dec. 1996) and Final Plan and EIS (Sept. 1997): • Final Plan Sections 6.4.2., 6.4.3., 6.4.6., 6.7.3., 6.8.2.2., 6.8.3. • Draft EIS Section 2 of Chapters 3-12. Is the property in agricultural land? No. 8. Proposed Activity: Include expected water quality and fish impacts, and proposed actions to reduce the duration and severity of those impacts and provide proper protection for fish life. Under this application the City of Renton proposes to implement the following elements defined in the ESGRWP Final Plan and EIS (Sept. 1997): • SW 23rd Street Drainage Channel Alternative 23ST3 - Element 1: Replace SR-167 Culvert Crossings with New Crossing at SW 23rd Street • Panther Creek Alternative PC2 -Element 1: Modify Existing Flow Split at SR-167 These alternatives are described in detail in Sections 8.3.2 and 8.3.3 of the Final Plan and illustrated in the drawings attached to this application. In summary the activities proposed include: c( a� 16i15t1 V#"1J1sVJL • Element 23ST3-1. Close veral poorly 9ctioning culverts across SR-167 and replace them with a new SR- ulvert crossing at SW 23rd Street. A control structure will be installed on the inlet to lvert to maintain the hydrology of the Panther Creek Wetland. Arikproximately 110 feeEe -A e lam e�n}d be co�new SR-167 culver�to connect'lo exists g culverts under East Valley Road. w.y � duf4, � • Element PC2-1. Close one of two SR-167 culverts that Panther Creek currently flows through and install a structure on the other culvert near SW 39th Street that allows low flows to pass into the existing system. Excess flows would be diverted into the Panther Creek Wetland, increasing the frequency of overflow into the wetland that already occurs under existing conditions (Element PC2-1). As a result of the EIS review process, additional measures were added to these elements at the request of the Washington State Department of Fish and Wildlife. The measures are described in Section 2.3.5 of the Final EIS and include: • Create an overflow"channel' from the Panther Creek SR-167 cross culvert to the nearest standing water in the Panther Creek Wetland by mowing/cutting a path through the existing reed canarygrass and planting willows and cottonwoods (where 12/16/97 Draft conditions are suitable) on each side of the mowed path to provide cover and habitat diversity. • Design the proposed SR-167 culvert at SW 23rd Street so as to not preclude fish passage into the Panther Creek Wetland in the future. Implementation of these elements is designed to continue to allow downstream migration of fish in the Panther Creek system while improving the potential for restoring upstream fish passage to Panther Creek in the future (SR-167 is the first of several upstream fish migration barriers on Panther Creek). The project reduces downstream flooding problems and the related impacts while providing a reliable outlet from the Panther Creek Wetland that may be easily accessed and maintained. The project is also designed to maintain and even improve the function of the affected wetland syste S> ) Impacts and Mitigation Measures: The impacts of the proposed activities and related mitigation measures are analyzed in detail in the ESGRWP Draft EIS (December 1996) and Final EIS (September 1997) under Alternatives PC2 - Element 1 and 23ST3 Element 1. The attached EIS Mitigation Document(September 1997)presents the preferred alternative and mitigation measures adopted by the City of Renton for the ESGRWP at the conclusion of the EIS process. Refer to Alternatives PC2 - Element I and 23 ST3 Element 1 in Tables 1 through 10 of the Mitigation Document for a summary of the impacts and mitigation measures identified for the activities proposed under in this application. 9.

JZJI- Project Narrative A. Proposed Activities Under this application the City of Renton proposes to implement the following elements defined in the East Side Green River Watershed Project(ESGRWP)Final Plan and EIS(City of Renton, Sept. 1997). In summary the activities proposed include: ruk- &J'K /• t#e' 6 dF I'AOA • Alternative Element 23ST3-1. Close several poorly functioning ctllCerts across SR-167 and replace them with a new SR-167 culvert crossing at SW 23rd Street. A control stn14 will be installed on the inlet to the culvert to ma a tdrol o h P,Cher reek W t d %}fin a�proxima�foot outlet channel woul e constructed frout the new SR-167 culvert to onnect to existin culverts under East Valley Road. • A temtative Element PC2- . se one-of SR-167 culverts that Panther Creek currently flows through and install a structure on the other culvert near SW 39th Street that allows low flows to pass into the existing system. Excess flows would be diverted into the Panther Creek Wetland, increasing the frequency of overflow into the wetland that already occurs under existing conditions(Element PC2-1). • Create an overflow"channel'from the Panther Creek SR-167 cross culvert to the nearest standing water in the Panther Creek Wetland by mowing/cutting a path through the existing reed canarygrass and planting willows and cottonwoods(where conditions are suitable)on each side of the mowed path to provide cover and habitat diversity. • Design the proposed SR-167 culvert at SW 23rd Street so as to not preclude fish passage into the Panther Creek Wetland in the future. Implementation of these elements is designed to continue to allow downstream migration of fish in the Panther Creek system while improving the potential for restoring upstream fish passage to Panther Creek in the future(SR- 167 is the fast of several upstream fish migration barriers on Panther Creek). The project reduces downstream flooding problems and the related impacts while providing a reliable outlet from the Panther Creek Wetland that may be easily accessed and maintained. The project is also designed to maintain and even improve the overall function of the affected wetland system. B. Impacts of the Proposed Activities The ESGRWP EIS Mitigation Document(September 1997)presents the preferred alternative and mitigation measures adopted by the City of Renton for the ESGRWP at the conclusion of the EIS process. A detailed summary of the impacts and mitigation measures identified for the activities proposed under in this application are included in Tables 1 through 10 of the EIS Mitigation Document under Alternatives PC2-Element 1 and 23ST3 Element 1. A copy of the Mitigation Document may be obtained by contacting Scott Woodbury of the City of Renton at 425-277- 5547. --"& y2oo About ZHQ'sq. ft. of palustrine wetlands will be temporarily disturbed by construction activities and then restored. Approximately 300 sq. ft. of Renton inventory Wetland W-4 and 100 sq. ft. of Wetland W48e will be filled by the culvert installation and riprap placement under the proposed SW 23rd Street culvert crossing of SR-167. C. Mitigation Plan Wetland W4 is a Category 1 wetland and W48e is a Category 3 wetland under the City of Renton Wetlands Management Ordinance. A total of approximately 1250 sq. ft.of wetlands will be created adjacent to the outlet of the proposed culvert at SW 23rd Street to mitigate for the wetland impacts in accordance with the City of Renton regulations(see Figures 10 and f . xx-x-xxxxx SR-167 Culvert Modifications 12/16/97 Draft IN: Wetlands Adjacent to Panther Ck./fributary to Springbrook Ck.

They are defined as those areas that are inundated or saturated by surface 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 soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas (Environmental LaToratory, 1987).

Although you have been involved in our coordination with WSDOT since the SR-167 lane widening was initiated, we wanted to provide you a detailed overview of the sequence of events and the previous commitments that have been made regarding the planned SR-167 culvert improvements. WSDOT is currently trying to find additional funding, but we wanted to make sure you we got this information to you in the event WSDOT contacts you regarding their funding problem. Overview of Events 1993. As part of its SR-167 lane widening project, WSDOT agreed to jack two 54" culvert across SR-167 at SW 23rd Street, abandon several existing cross culverts,and clean an existing 48"cross culvert near SW 29th Street. This was selected in lieu of providing detention for the lane widening project. 1994. On May 6, 1994, the Corps of Engineers issued a stop work order on the SR-167 lane widening project for any work outside of the median of the roadway. WSDOT indicated they would drop the drainage improvements outside of the median from their construction contract. 1994. The City Council sent Sid Morrison, the Washington State Secretary of Transportation, the attached letter requesting WSDOT reconsider eliminating the drainage improvements from their lane widening construction contract. The Mayor also sent a similar letter. 1994. Ron Anderson of WSDOT responded to the City's letters on behalf of Sid Morrison in the attached letter dated July 22, 1994. Mr. Anderson cited several reasons for why the drainage improvements needed to be deferred from the lane widening contract. He also said WSDOT was committed to working expeditiously to redesign the drainage improvements, obtain the necessary permits, and award a new contract to construct the improvements. As a interim measure prior to construction of the drainage improvements, WSDOT would perform maintenance of the existing SR-167 culverts as the City requested. • Gregg Zimmerman Background and Status of SR-167 Culvert Improvements Page 2 1995. In the process of preparing its application to the Corps of Engineers to address the wetlands violations, WSDOT invited the City to attend a joint meeting with the Corps on March 8, 1995, to discuss the culvert crossing through SR-167 at SW 23rd Street. At the meeting, WSDOT stated that the issue was not if WSDOT was committed to installing the culvert crossing, but when the culvert crossing would be installed. WSDOT requested the concurrence of the City to further delay installing the culvert crossing primarily for the following reasons: • to coordinate the permitting for the culvert crossing with the City's comprehensive drainage planning effort for the valley area as proposed under the East Side Green River Watershed Project. • to streamline the permitting process for the wetlands violation application so that WSDOT could maintain a planned July 1995 bidding deadline for construction the violation wetland mitigation. The Corps representative also suggested that the culvert crossing would be more appropriately handled as a separate application from the WSDOT wetland mitigation. (WSDOT staff report that the wetland mitigation is still pending because of problems in acquiring the'desired mitigation site in the.City of Auburn.) • to allow sufficient funds to be appropriated for the culvert crossing that were not currently available because of current budgetary constraints. To provide the City with assurance of WSDOT's commitment to install the culvert crossing, WSDOT proposed documenting that commitment in a Letter of Understanding. WSDOT issued the attached Letter of Understanding dated May 24, 1995, outlining the City and WSDOT's agreed upon responsibilities for the culvert improvement (City file No. CAG-95-056). In the letter, WSDOT committed to fundidg the SR-167 culvert construction. The City would be responsible for obtaining the necessary permits. 1996. WSDOT allocated $80,000 for design and $401,000 for construction of the proposed SR- 167 culvert crossing at SW 23rd Street in their 1997 budget: The cost estimate used for the budget allocation was reportedly based on the prior proposal to jack two 54"culverts across SR-167. 1996. The City issued a Draft Plan and EIS for the East Side Green River Watershed Project in December 1996. WSDOT also initiated their preliminary design process for the SR-167 drainage improvements. 1997. WSDOT conducted additional soil investigations and was advised by WSDOT geotechnical staff that pipe jacking was not an acceptable construction method. Because of the need to open cut, WSDOT's cost estimate for construction was once as high as $880,000, but has since be revised downward to $660,420, including sales tax, 15% engineering and 5% construction contingencies, and 10% for mobilization, but excluding any channel improvements from SR-167 to East Valley Road. The City will be asked to pay for the channel improvements which fall outside of WSDOT right-of-way. As part of its construction work, WSDOT will also: • install a high flow diversion on the existing 30-inch Panther Creek culvert crossing of SR-167 near Valley Medical Center. • plug existing culvert crossings under SR-167 south of SW 23rd Street to SW 43rd Street, except at the above-referenced 30-inch Panther Creek culvert. Current Status We expect WSDOT to provide by the end of the week the draft drawings and wetland information we need to complete and submit a JARPA (Joint Aquatic Resources Permit Application) for the SR-167 culvert improvements to the Corps of Engineers and other agencies. In terms of the Gregg Zimmerman Background and Status of SR-167 Culvert Improvements Page 3 permitting schedule, we are on the critical path if construction is to be completed this summer. We will continue to diligently work with WSDOT staff on achieving this objective. However, the funding issue will need to be resolved, of course, before WSDOT can bid the project. Assuming no problems are encountered during the permit review process, it is estimated that the project could be advertised for bids in late July with construction occurring in September and October when groundwater levels are lowest. Finally, because we will need to fund the approximately 100 feet of channel construction outside of WSDOT rjght-of-way, we will need to either develop a local agency agreement with WSDOT to pay for the work or conduct the work at part of a separate City contract. However, as it would be more difficult to coordinate the work of two separate contractors in such a limited area, our preferred approach is to pursue a local agency agreement with WSDOT. We trust that this information is helpful. If you have any questions, please contact Ron Straka at X-5548 or Scott Woodbury at X-5547.

Because of the threat that the existing drainage problems pose and the increased. potential for flooding due to increases in impervious surfaces, the City of Renton requests.and expects WSDOT to start construction of the following improvements.as soon as possible and to make significant progress toward their completion prior to the start of the rainy season: 1. clean and regrade the existing SR-167 west roadside ditch to restore positive drainage to the existing SR-167 cross culverts; 2. clean and maintain the existing SR-167 cross culverts to ensure the culverts operate at.full capacity as originally designed; 3. install the new twin 54" SR-167 cross culverts at SW 23rd Street as proposed in the SR-167 project plans and permit documents; 4, install a new SR-,167 cross culvert for Upper Springbrook Creek at South 192nd Street as previously requested by City staff. Sid Morrison, Washington State Department of Transportation Page t WSDOT staff have informed the City that the Corps of Engineers has issued a stop work order for any work outside of the median, that none of the above work may proceed without the Corps lifting the stop work order, and that the current construction contract awarded for the SR-167 project.will be closed out without any of the above work being completed. Because removal of the stop work order for.the area within the City is urgently needed, we are willing to provide assistance to WSDOT in coordinating with the Corps of Engineers. To minimize further delays once the Corps stop work is removed, we request that WSDOT reconsider closing out the current construction contract for the above work. Having to advertise and award a new contract increases the risk that a severe storm event will occur without having completed the above mitigating improvements. We look forward to continued coordination from WSDOT staff concerning the status of the above improvements. Your assistance is appreciated.

Dear Mayor Clymer: Mr. Morrison has asked me to respond to your letter dated July 12, 1994. The letter expressed concern with the progress of remaining work on the SR 167 project within the city of Renton. Mr. Morrison also received the same letter from the Renton City Council; I will respond by sending them a copy of this response. As stewards of the state highway system we obviously share your concern that construction was stopped prior to contract completion. On May 6, 1994, the Corps of Engineers (COE) issued a stop work order for any work outside the shoulders of the highway. Work within the median and.work on the roadway surface itself was not stopped. It is accurate, for reasons discussed below, that we are moving to close the existing construction contract at the end of this construction season. The work outside the shoulders was stopped because several wetland areas were impacted without permit. These non-permitted impacts, while inadvertent on the part of WSDOT, are a serious violation of federal wetland protection law. Most of the non-permitted impacts resulted from the construction of swales and ponds designed specifically to address water quality for fish habitat. Earth fills and retaining walls, designed to widen ramps for additional lanes, account for most of the remaining non-permitted impacts. We are working at full speed to redesign the drainage features and water quality features of the project to minimize impacts to wetland areas. The Department of Ecology (DOE) and the Department of Fish and Wildlife (DFW) are coordinating closely with us in this endeavor. DOE and DWF have been very supportive and are in conceptual agreement that alternative water quality features can be designed outside of any wetland areas. ti Mayor Clymer July 22, 1994 Page 2 Once a new design is complete to the satisfaction of DOE and DFW we will submit an application to the COE for completion of all necessary project work within wetlands. Unfortunately, this redesign of sensitive drainage and water quality features is a large task. Even with the full cooperation of all agencies it will take, optimistically, six months or more to complete design and receive COE approval for work to restart. Given no unforeseen difficulties it will be next spring at the earliest before construction could resume on the deferred work. While we remain committed to successful completion of all project work we are also faced with the difficult problem of identifying funds to cover the significant cost overruns. We are sensitive to the need to complete all remaining work as soon as possible. At the same time it is painfully evident the deferred work cannot begin for several months, and perhaps as long as a year or more. We have also determined that total project costs could be significantly reduced by minimizing extended delay and impact costs to the current contractor. For these and other reasons we feel it is imperative to close the existing construction contract. We appreciate and thank you for your willingness to provide assistance in coordinating with the COE. The permitting process for the deferred work will take less time given your help and the ongoing assistance of DOE and DFW. Additionally, we will be making every effort to secure funding, design, advertise and award the new contract in the most efficient manner possible. Your letter addresses four items by number: 1) The roadside channel along the west side of SR 167 is a regulatory wetland. It would be a violation of federal wetland protection law to clean or regrade this channel without a permit from the COE. Any work within this, or other, wetlands will be part of the future contract to complete all remaining project work. 2) We will do our very best to clean and maintain all existing cross culverts. 3) The entire hydrology of the project is being reviewed and redesigned. The hydrology review must include consideration of potential impacts from the twin 54-inch diameter culverts to adjacent wetlands. It is possible these culverts may be resized, relocated or, given extreme Mayor Clymer July 22, 1994 Page 3 hydrology findings, even eliminated. It would be premature and possibly a violation of law to install the culverts at this time. Most likely, these twin culverts will be built as part of the future project. 4) This proposed new culvert will be designed as part of the overall project hydrology. As with the 54-inch culverts, consideration must be given to potential wetland impacts. This new cross culvert will likely be built as part of the future project. Your letter clearly expressed a desire that the listed improvements be in place or well underway by the rainy season. As discussed above it will not be possible to construct any feature within wetlands prior to obtaining a new permit from the COE. While the deferred work will improve existing drainage conditions we are confident the delay will not measurably increase any potential for flooding. The added runoff from the new impervious surface is extremely small in proportion to the existing runoff of the affected drainage basins. Thank you again for your concerned interest in this very serious matter and for your offer to assist. Please call me at (206) 440-4691 if you wish to discuss any aspect of this project. .

Renton, WA 98055 MEMORANDUM OF UNDERSTANDING: Proposed Culvert Crossing SR 167 in the vicinity of SW 23rd Street Dear Gregg: WSDOT held a meeting on March 8, 1995 to consider the design and scheduling of a proposed culvert crossing SR 167 in the vicinity of SW 23rd St. (P-9 Channel). Attending the meeting were Kristina Tong (Corps of Engineers), Ron Straka and Scott Woodbury (City of Renton) and several representatives of WSDOT (see attached list of attendees). This meeting was prompted by the following circumstances. A recent WSDOT Contract was halted due to a wetland violation. Work now deleted from this contract includes a major culvert crossing SR 167. Wally Hendricks stated this culvert was committed to the City of Renton in lieu of restoration of several existing smaller culverts which are now inoperative. Ron Straka discussed a major drainage study the City of Renton is now conducting in the WSDOT project area. The study may recommend improvements to the P9 Channel to-the west of SR 167 (see attached sketch), the proposed culvert crossing SR 167, and future possible diversion of flood waters through the Panther Creek Wetland to the culvert crossing from the east side of SR 167. More studies and further coordination are required with the Corps of Engineers in the planning phase and later permit processing phase. The City expects the study to result in a project to improve drainage across SR 167 from east to west through an open channel which will eliminate existing flooding problems and benefit water quality and aquatic habitat. Kristina Tong asked that there be only one permit requested at the culvert crossing SR 167 and preferably coordinated with City proposals on both sides of SR 167. She recommended mimimizing impacts to the aquatic environment. I .. ... - r.-..._ .R e I. �•�,. .i U Greg Zimmerman May 24, 1995 Page 2 Conclusion The City of Renton's drainage study and permit applications will take a year or longer to complete. During this time WSDOT will develop, at its sole expense, a separate contract and fund the construction of just the culvert crossing. The City will obtain necessary permits and develop the appropriate schedules at the City's sole expense. In that way the permit processing and contract development for the end to end facility will be orderly and the construction schedule precisely controlled. To make sure this is a proper representation of our,consensus approach a copy of this letter is going to the Corps of Engineers and we would appreciate a signature of concurrence from the City of Renton. A returned copy of this letter with a signature below may be the most effective approach. Thanks again for the participation of the City of Renton and Corps of Engineers Staff in the March 8 meeting.

Although you have been involved in our coordination with WSDOT since the SR-167 lane widening was initiated, we wanted to provide you a detailed overview of the sequence of events and the previous commitments that have been made regarding the planned SR-167 culvert improvements. WSDOT is currently trying to find additional funding, but we wanted to make sure you we got this information to you in the event WSDOT contacts you regarding their funding problem. Overview of Events 1993. As part of its SR 167 lane widening project, WSDOT agreed to jack two 54"culvert across SR-167 at SW 23rd Street,abandon several existing cross culverts,and clean an existing 48" cross culvert near SW 29th Street. This was selected in lieu of providing detention for the lane widening project. 1994. On May 6, 1994, the Corps of Engineers issued a stop work order on the SR-167 lane widening project for any work outside of the median of the roadway. WSDOT indicated they would drop the drainage improvements outside of the median from their construction contract. 1994. The City Council sent Sid Morrison, the Washington State Secretary of Transportation, the attached letter requesting WSDOT reconsider eliminating the drainage improvements from their lane widening construction contract. The Mayor also sent a similar letter. 1994. Ron Anderson of WSDOT responded to the City's letters on behalf of Sid Morrison in the attached letter dated July 22, 1994. Mr. Anderson cited several reasons for why the drainage improvements needed to be deferred from the lane widening contract. He also said WSDOT was committed to working expeditiously to redesign the drainage improvements, obtain the necessary permits, and award a new contract to construct the improvements. As a interim measure prior to construction of the drainage improvements, WSDOT would perform maintenance of the existing SR-167 culverts as the City requested. Gregg Zimmerman Background and Status of SR-167 Culvert Improvements Page 2 1995. In the process of preparing its application to the Corps of Engineers to address the wetlands violations, WSDOT invited the City to attend a joint meeting with the Corps on March 8, 1995, to discuss the culvert crossing through SR-167 at SW 23rd Street. At the meeting, WSDOT stated that the issue was not if WSDOT was committed to installing the culvert crossing, but when the culvert crossing would be installed. WSDOT requested the concurrence of the City to further delay installing the culvert crossing primarily for the following reasons: • to coordinate the permitting for the culvert crossing with the City's comprehensive drainage planning effort for the valley area as proposed under the East Side Green River Watershed Project. • to streamline the permitting process for the wetlands violation application so that WSDOT could maintain a planned July 1995 bidding deadline for construction the violation wetland mitigation. The Corps representative also suggested that the culvert crossing would be more appropriately handled as a separate application from the WSDOT wetland mitigation. (WSDOT staff report that the wetland mitigation is still pending because of problems in acquiring the desired mitigation site in the City of Auburn.) • to allow sufficient funds to be appropriated for the culvert crossing that were not currently available because of current budgetary constraints. To provide the City with assurance of WSDOTs commitment to install the culvert crossing, WSDOT proposed documenting that commitment in a Letter of Understanding. WSDOT issued the attached Letter of Understanding dated May 24, 1995, outlining the City and WSDOT's agreed upon responsibilities for the culvert improvement (City file No. CAG-95-056). In the letter, WSDOT committed to funding the SR-167 culvert construction. The City would be responsible for obtaining the necessary permits. 1996. WSDOT allocated $80,000 for design and $401,000 for construction of the proposed SR- ` 167 culvert crossing at SW 23rd Street in their 1997 budget. The cost estimate used for the budget allocation was reportedly based on the prior proposal to jack two 54"culverts across SR-167. 1996. The City issued a Draft Plan and EIS for the East Side Green River Watershed Project in December 1996. WSDOT also initiated their preliminary design process for the SR-167 drainage improvements. 1997. WSDOT conducted additional soil investigations and was advised by WSDOT geotechnical staff that pipe jacking was not an acceptable construction method.

Your letter clearly expressed a desire that the listed improvements be in place or well underway by the rainy season. As discussed above it will not be possible to construct any feature within wetlands prior to obtaining a new permit from the COE. While the deferred work will improve existing drainage conditions we are confident the delay will not measurably increase any potential for flooding. The added runoff from the new impervious surface is extremely small in proportion to the existing runoff of the affected drainage basins. Thank you again for your concerned interest in this very serious matter and for your offer to assist. Please call me at (206) 440-4691 if you wish to discuss any aspect of this project. .

MAY 3 11995 Administrator City of Renton,Dept. of Planning/Building/Public Works CITY OF RE14TON PUBLIC WORKS ADMIN. 200 Mill Avenue So, Renton, WA 98055 MEMORANDUM OF UNDERSTANDING: Proposed Culvert Crossing SR 167 in the vicinity of SW 23rd Street Dear Gregg: WSDOT held a meeting on March 8, 1995 to consider the design and scheduling of a proposed culvert crossing SR 167 in the vicinity of SW 23rd St. (P-9 Channel). Attending the meeting were Kristin Tong(Corps of Engineers), Ron Straka and Scott Woodbury(City of Renton) and several representatives of WSDOT (see attached list of attendees). This meeting was prompted by the following circumstances. A recent WSDOT Contract was halted due to a wetland violation. Work now deleted from this contract includes a major culvert crossing SR 167. Wally Hendricks stated this culvert was committed to the City of Renton in lieu of restoration of several existing smaller culverts which are now inoperative. Ron Straka discussed a major drainage study the City of Renton is now conducting in the WSDOT project area. The study may recommend improvements to the P9 Channel to'the west of SR 167 (see attached sketch), the proposed culvert crossing SR 167, and future possible diversion of flood waters through the Panther Creek Wetland to the culvert crossing from the east side of SR 167. More studies and further coordination are required with the Corps of Engineers in the planning phase and later permit processing phase. The City expects the study to result in a project to improve drainage across SR 167 from east to west through an open channel which will eliminate existing flooding problems and benefit water quality and aquatic habitat. Kristina Tong asked that there be only one permit requested at the culvert crossing SR 167 and preferably coordinated with City proposals on both sides of SR 167. She recommended mimimizing impacts to the aquatic environment. .CB AA� >f i �N f y .14 F{4 t^ Greg Zimmerman May 24, 1995 Page 2 Conclusion The City ofRenton's drainage study and permit applications will take a year or longer to complete. During this time WSDOT will develop,at its sole expense, a separate contract and fund the constriction of just the culvert crossing. The City will obtain necessary permits and develop the appropriate schedules at the City's sole expense. In that way the permit -: processing and contract development for the end to end facility will be orderly and the construction schedule precisely controlled. To make sure this is a proper representation of our consensus approach, a copy of this.letter is going to the Corps of Engineers and we would appreciate a signature of concurrence from the City;of Renton. A returned copy of this letter with a signature below may be the most effective approach. Thanks again for the participation of the City of Renton and Corps of Engineers Staff in the March.8 meeting.

I have appreciated all of your efforts to help make construction this year a reality and request your continued assistance. However, with the month of May upon us later this week, I am becoming very concerned about the our ability to obtain the permits in the time frame necessary for WSDOT to construct the SR-167 culvert improvements in September and October this year (the time when groundwater and wetland water levels are at their lowest). Please provide as soon as possible (this week would be preferred) the conceptual design drawings and wetland information (paper and digital copies) I had requested in early March so that we can submit the 7ARPA to the Corps of Engineers and other agencies. I know that you are also working on the projected budget shortfall issue on this project. However, it is important that we keep the permitting and design process moving forward in accordance with the original plan for accomplishing construction this year. Also, no one has contacted us about rescheduling the meeting that had been postponed last week. Would you please update me on the status of the meeting arrangements?

Box 330310 Seattle, WA 98133-9710 SUBJECT: COMMENTS TO MARCH 20, 1997,PRELIMINARY DESIGN EVALUATION MEMO FOR SR-167 CULVERT IMPROVEMENTS Dear Ms. Suafoa: Thank you for the opportunity to review your March 20, 1997, memorandum regarding the preliminary design evaluation for the proposed SR-167 culvert improvements in Renton. Following are my preliminary design review comments to your March 20th memorandum. 1) The culvert upstream invert at SW 23rd Street should be elevation 8; otherwise, the slope of the culvert will be greater than 0.5%. The preliminary plans of your memorandum show the elevation to be 9. Placing the upstream culvert invert at 8 will allow a foot of gravel to be placed in the culvert invert and still be deep enough to allow extension of a channel into the wetland as part of a future project. 2) The weir structure should not be right inside the inlet to the culvert as shown in section A-A of Alternative 3. The inlet structure must have the ability for overflows to bypass the weir once the water elevation in the wetland reaches 16 feet. The ability to have unrestricted flow once the water elevation reaches 16 feet was a parameter that Bob Winter wanted to see in the design of the inlet control structure. 3) Please send me a copy of page 1 of 3 of boring log H-1-97. Also, it would be helpful if you could provide a plan of where the borings were done. 4) If you are able to do geotechnical borings at the SR-167 192nd Street culvert crossing at Upper Springbrook Creek, I suggest installing a piezometer for monitoring ground water levels at South 192nd and if possible installing a ground water monitoring well at SW 23rd Street. We could monitor the wells periodically which would provide additional information on how ground water levels may affect construction. 5) In Alternative 1 the 132-inch manhole would be located in the access road, not at the end of the culvert. It would be helpful to show the manhole location on the culvert profile as it may make a difference in the geotechnical conclusions. 6) The culvert at SW 23rd Street should have one foot of gravel on the bottom of the culvert. 200 Mill Avenue South - Renton, Washington 98055 Oak----------- . . -_. Rumina Suafoa, Washington State Department of Transportation SR-167 Culvert Preliminary Design Evaluation Comments Page 2 7) The WSDOT standard specification calls for gravity drain construction to proceed in a downstream to upstream direction. Does the direction of the construction make a difference at the SW 23rd Street culvert? 8) I believe it is important that we provide a weir design similar to Alternative 1 in the other alternatives as well. The Alternative 1 design maintains the flexibility to adjust weir width. Also, it makes weir removal easier in the future if desired for fish passage. 9) The flow area of the 6'x7' box culvert, assuming one foot of gravel in the bottom, is nearly the same as the 7-foot diameter culvert. The box culvert will have a greater wetted perimeter so its flow conveyance will be somewhat less than the 7-foot culvert. However, the conveyance of the 6'x7' box culvert with one foot of gravel is similar to a 6-foot diameter culvert without gravels. 10) As soon as possible, would you please add the Panther Creek overflow "channel" to the plans according to the information I sent you on March 20, 1997. 11) There should be no more than 20 square feet of impact at the Panther Creek diversion structure. Please provide a detail of the work at Panther Creek and typical detail of the culverts that will be plugged. 12) The culvert at Station 1071+10 also needs to be plugged. 13) Please also show the channel work downstream of the SR-167 culvert as soon as possible. Based on the review of the plans, the area shown as being impacted downstream of the SR-167 culvert at SW 23rd Street appears to being angled too sharply to the south. Thank you again for the opportunity to comment on your March 20th memo. We are still hopeful that you will be able to provide a complete conceptual set of drawings by April 14 for our use in developing the Corps permit applications. If you have any questions, please contact me at(206)277-5547.

Witecki MS 47239 Please provide preliminary design review comments for the culvert construction on this project. Attached are the following documents for your use: - Plan sheets showing the proposed culvert, Station L 1121+00 - Culvert profile - Vicinity map - Geotechnical Report - Alternative details The culvert crossings on SR 167 between SW 23rd Street and SW 34th are inadequate for drainage and are a long term concern for the city of Renton. The City of Renton will work to improve the drainage in the area mentioned, thru enhancement of the Panther Creek wetland and the P-9 channel. This project proposes to plug the poorly functioning SR 167 culverts between the southernmost culverts and SW 23rd Street. There will be a new culvert constructed under SR 167 in the vicinity of 23rd Street. We conclude that open cut will be used for this operation. There will be approximately 18 to 20 feet of excavation needed. Additional information is provided on the details for the alternatives. According to the Geotechnical Report dated March 4,1997, the existing soil conditions will make the installation of the culvert and the control structure difficult because: 1. Excessive settlement may take place due to the soil structure. 2. During high flows, there may be uplift pressure on the structure and cause buoyancy. 3. Ground water may be encountered during trench construction. Dewatering is not recommended, due to potential settlement caused by the sudden drawdown of the ground water. OL 2836 SR 167 T. ALLEN MS 47365 M. WITECKI MS 47239 Page 2 We have provided three different alternatives for this project. All of these alternatives have a 220 feet long culvert and an inlet control weir in common. Alternative 1 uses a circular 7 ft diameter pipe connected to a 11 ft diameter manhole with a weir control structure. Alternative 2 uses a 7 ft diameter pipe connected to a rectangular control structure. Alternative 3 proposes to install a 6 ft X 7 ft rectangular culvert connected to a control structure with a 3.5 ft adjustable weir. In alternatives 2 and 3 there will be an approach slab before the 3.5 ft adjustable weir. This letter requests your recommendations on the foundation material that would be suitable for pipe bedding, backfill, and whether pile support is needed to oppose settlement. We also request that all three alternatives be evaluated for buoyancy potential and that a recommendation be provided for anchoring. Please evaluate all of the alternatives and provide your comments by April 3, 1997. If you have any questions or need any additional information please contact Mohammad Saleem at 440-4559.

The new culvert will be located approximately 0.6 miles south of the junction of SR-405 and SR-167 at project Station 1120+80 (vicinity of SR-167 MP 25.69) in Renton. The new culvert is needed to enhance the drainage under SR-167 between the Panther Creek wetland and the P-9 channel. The analyses, conclusions, and recommendations presented in this memorandum are based on the project description and site conditions that existed at the time of the field exploration. We assume the exploratory borings represent the subsurface conditions throughout the project area. If different subsurface conditions are encountered or appear to be present, we should be contacted so that we can reevaluate our recommendations and assist you. FIELD EXPLORATION The field exploration program for the project consisted of field reconnaissance, review of historical records, and drilling 2 test borings. Standard Penetration Tests (SPT) were performed in the test borings. The information obtained during the field exploration was used to characterize the subsurface conditions throughout the project area. Standard Penetration Tests (SPT) were generally performed at 5 ft intervals in the test borings. Undisturbed Shelby and Washington Undisturbed samples were obtained in soft soil units. Disturbed soil samples from the SPT were visually classified in the field then submitted to the FOSSC Materials Laboratory for more detailed classification and testing. Hong West& Associates had previously performed a geotechnical investigation at this site. The report titled "SR-167 84th Ave. South to South Grady Way, Stage 1"was completed May 21, 1993. Two test borings were drilled at the ends of the culverts ( B-10 and B-11). Table 1 lists the test boring numbers, locations, and elevations. The edited logs of the test borings are attached in Appendix A. The edited logs of the test borings should be included in the contract documents. A John Johnson/R.

Laboratory testing was performed on selected sample from the fie13 exploration program. All disturbed soil samples were visually examined and then grouped together based on particle size distribution, consistency, and color. Once groups of samples were established that had similar characteristics, a minimum of one sample per group was tested. The testing consisted of performing particle size analyses, determining the liquid limit if applicable, and determining the plastic limit and plasticity index if applicable. The tests were done in accordance with AASHTO T-88, T-89, and T-90 guide specifications respectively. After the testing was complete, the samples were classified using the Unified Soil Classification System(USCS). The results of all laboratory testing are attached in Appendix B. PROJECT SOIL CONDITIONS The soil materials encountered during the field investigation have been grouped into four general soil units based on engineering properties and material classifications. The units are ' briefly described below: Unit 1 Fill - loose to medium dense, well graded sand to silty sand with gravel. Unit 2 Soft peat and organic silt with wood fragments. Unit 3 Soft sandy silt to elastic silt with an intermediate medium dense, silty sand layer. The intermediate layer consist of volanic debris which varies in thickness between 4 ft and 7 ft under the culvert. Unit 4 Medium dense to dense, interbedded layers of well graded sand and gravel to silty sand. In general, Unit 1 is underlain by Unit 2, which is underlain by Unit 3. Unit 3 is underlain by Unit 4. The flow line (bottom) of the culvert vanes between elevation 9.0 ft and elevation John Johnson/R. Suafoa March 4, 1997 Page 3 TO ft. The flow line is located near the Unit 1 and Unit 2 contact. Unit 2 soil will be encountered under the flow line of the culvert. The thickness of the highly compressible organic soil (Unit 2) varies between 3 ft to 10 ft under the culvert. Soil Unit 3 is approximately 17 ft thick. GROUND WATER Ground water was encountered at varying elevations at the time of field exploration. Ground water was seen at approximate elevation 12 ft west of SR-167 and at approximate elevation 14 ft east of SR-167 on January 10, 1997. Ground water was encountered in test boring B-11-93 at approximate elevation 6.5 ft west of SR-167. Ground water was seen at approximate elevation 8.5 ft in test hole H-10-93 east of SR-167. Both test holes (B-10 and B 11) were drilled on February 25, 1993. The field exploration was conducted during the wet time of the year. We expect that the water will vary seasonally. We recommend that the culvert be excavated during the dryer time of the year between July to October. GEOTECHNICAL RECOMMENDATIONS A 230 ft long, 84 inch round culvert is proposed in the vicinity of project Station L 1120+80. The flow line (bottom) of the culvert varies between elevation 9.0 ft and elevation 7.0 ft. The flow line is located near Unit 1 and Unit 2 soil contact. The amount of cover over the culvert and the roadway will be between 8 ft and 10 ft. The new.culvert site is located south of existing utilities. The utilities are overhead power lines, oil/gas pipe lines and buried waterlines. The buried oiUgas lines are approximately 70 ft from the new culvert. Pipe jacking is not considered feasible for the diameter and length of the proposed culvert. We are concerned with the integrity of the existing roadway if pipe jacking is used. The following are some of reasons that pipe jacking should be removed from consideration: 1. The site of the proposed jacking pit will be located or soft soil with a high ground water table. 2. The pit would.require some "impermeable' enclosed cell or cofferdam with a pile supported reaction frame in order to push the culvert. 3. Dewatering should not be allowed. If dewatering is allowed for construction of the culvert, damage to the roadway and existing utilities is likely. Changes in ground water will induce settlement under the existing roadway embankment. Settlements up to a foot are possible if dewatering is allowed. 4. The mixed-face conditions (e.g. part of the heading will be in relative high quality embankment materials, while the bottom will be in soft peats and organic silts) will likely create construction problems. This will affect the control of grade of the culvert and the probability of a potential cave in. 5. The small amount of cover in relationship of the pipe diameter could create a sink hole which would propagate rapidly to the driving surface. We recommend that cut-and-cover construction methods be used. John Johnson/R. Suafoa March 4, 1997 Page 4 The flow line (bottom) of the pipe will be at an elevation where up to 7 ft of peat and organic silt (Unit 2 soils) currently exist. We recommend over-excavating a minimum of 2 ft below the culvert. The over-excavation section will provide a stable base for the bedding/ construction surface for the culvert. We recommend a layer of high-strength geotextile as a separation barrier between the organic soil and new backfill. The geotextile should meet the requirements for Soil Stabilization in Section 9-33 in the Standard Specifications. The over- excavated cavity should be backfilled with shoulder ballast. The top of the shoulder ballast should be choked with gravel backfill for pipe zone bedding. We expect that ground water will be encountered during the.construction of the trench. As previously discussed, the water table is seasonally variable. We expect up to 6 ft of water could be encountered during construction. During the dry part of the year, the water table should be lower, but 2 ft or more of water may be encountered during construction. The total settlement of the new foundation will be equal to or less than 2.0 inches. The differential settlement along the culvert will be less than one inch. CONSTRUCTION CONSIDERATIONS Construction considerations that will require attention during design and construction of this project are as follows: 1. Temporary shoring may be needed to preserve the existing adjacent roadway. We expect that the culvert will be built in sections while crossing SR-167. Please note that the determination of the actual slope used for temporary excavation is the responsibility of the contractor. The contractor will have control over factors which affect the stability of the excavation slope, such as length of exposed slope, length of time the excavation is left open, and the exposure to inclement weather. 2. Ground water may be encountered during trench construction. Dewatering is rot recommended, due to potential settlement caused by the sudden drawdown of the ground water. Ground water is expected to vary both seasonally and in response to inclement weather changes. Ground water vaned up to 7 ft as seen from the field observations and in the existing test borings. 3. We recommend that a Suttunary of Geotechnical Conditions be included in the contract documents to identify potential construction difficulties. This document will be prepared by our office at the time of the final PS&E review. CLOSURE Logs of Test Borings, laboratory test data are included in Appendices A and B, respectively.

RuminaSuafoa FAX Washington State Department of Transportation P.O.Box 330310 Seattle,WA 98133-9710 SUBJECT: COMMENTS TO MARCH 20, 1997,PRELIMINARY DESIGN EVALUATION MEMO FOR SR-167 CULVERT IMPROVEMENTS Dear Ms. Suafoa: Thank you for the opportunity to review your March 20, 1997, memorandum regarding the preliminary design evaluation for the proposed SR-167 culvert improvements in Renton. Following are my preliminary design review comments to your March 20th memorandum. 1) The culvert upstream invert at SW 23rd Street should be elevation 8; otherwise, the slope of the culvert will be greater than 0.5%. The preliminary plans of your memorandum show the elevation to be 9. Placing the upstream culvert invert at 8 will allow a foot of gravel to be placed in the culvert invert and still be deep enough to allow extension of a channel into the wetland as part of a future project. 2) The weir structure should not be right inside the inlet to the culvert as shown in section A-A of Alternative 3. The inlet structure must have the ability for overflows to bypass the weir once the water elevation in the wetland reaches 16 feet. The ability to have unrestricted flow once the water elevation reaches 16 feet was a parameter that Bob Winter wanted to see in the design of the inlet control structure. 3) Please send me a copy of page 1 of 3 of boring log H-1-97. Also, it would be helpful if you could provide a plan of where the borings were done. 4) If you are able to do geotechnical borings at the SR-167 192nd Street culvert crossing at Upper Springbrook Creek, I suggest installing a piezometer for monitoring ground water levels at South 192nd and if possible installing a ground water monitoring well at SW 23rd Street. We could monitor the wells periodically which would provide additional information on how ground water levels may affect construction. 5) In Alternative 1 the 132-inch manhole would be located in the access road, not at the end of the culvert. It would be helpful to show the manhole location on the culvert profile as it may make a difference in the geotechnical conclusions. 6) The culvert at SW 23rd Street should have one foot of gravel on the bottom of the culvert. 200 Mill Avenue South - Renton, Washington 98055 /Lt�mrNRs �1i£ l� Revs[t� as' S�,J fuSSiR �£ d �Acb AK cv/ru CITY OF RENTON PLANNINGBUILDING/PUBLIC WORKS MEMORANDUM DATE: March 20, 1997 nnp^r� TO: Rumina Suafoa FROM: co oo ury SUBJECT: SR-167 DRAINAGE IMPROVEMENTS Following is my understanding of the items covered in our March 10 meeting. All elevations are NGVD 1929 datum. 1. The inlet control structure for the new 84-inch culvert at SW 23rd Street will be a 132-inch concrete manhole. The manhole will be set in the existing access road on the east side of SR- 167. The manhole will be fitted with an internal stop log weir to provide the City the flexibility to adjust the weir configuration in the future if needed. No seasonal modification of the weir is proposed at this time. The top of the flood control weir will be set at elevation 16 feet. A 3.5- foot wide opening will extend down the center of the weir to a sill at 12.5 feet. A 1-foot diameter or square opening with an invert of elevation 10 feet will function as the low flow outlet. 2. The Washington State Department of Fish and Wildlife (WDFW) does not want baffles inside the culvert at 23rd Street culvert. Fish will not be allowed to migrate upstream of the control structure into the Panther Creek Wetland at this time. Based on the invert elevation of the East Valley Road culverts, the 84-inch culvert could be set with an outlet invert elevation of 6 feet and an inlet invert elevation of 7 feet. The bottom foot or so of the culvert would be filled with gravels. No baffles or weirs would be necessary as the bottom slope from the inlet of the East Valley Road culverts on upstream through to the inlet of the 84-inch culvert would be 0.5% or less. 3. Rootwads and other fish habitat will be incorporated into the channel between East Valley Road and SR-167. 4. I agreed to provide survey information on the elevations of the East Valley Road culverts. 5. Construction methods for installing the 84-inch culvert are still being evaluated. Open cutting is currently considered the least costly option, but is currently estimated at $870,000. This exceeds the current budget for the project. The availability of additional WSDOT funding will be investigated with WSDOT administration as soon as possible. 6. The decision on whether open cutting is the preferred option needs to be made as soon as possible so that the City's Final EIS may address the impacts and mitigation of open cutting. The Draft EIS was based on the use of the jack and bore method. _ SW 16th Street, Stage 1 Project ' i 90%Design Review Page 2 7. If open cutting will be used, it was agreed that it may be advantageous to consider also using the open cut method for the proposed culvert replacement on Upper Springbrook Creek at S. 192nd Street. The S. 192nd Street culvert crossing is currently planned for construction under a separate WSDOT project. The WDFW HPA permit has already been granted for the culvert. WSDOT is considering conducting a geotechnical study of the S. 192nd culvert crossing. 8. With regard to the Panther Creek diversion structure, WDFW commented on the Draft EIS that an overflow "channel" be created from the diversion structure to the standing water in the Panther Creek Wetland by mowing/trimming a path through the reed canary grass and planting willows on each side of the mowed path. No excavation would be needed. The mowing would not be needed once the willows became established to shade out the canary grass. The purpose of the overflow"channel"would be to reduce the potential for fish washed out of the stream by the operation of the diversion from being stranded in the dense canary grass before they can reach the portion of the wetland with standing water. I agreed to provide a sketch of the overflow"channel'. 9. The diversion structure at Panther Creek would simply consist of installing a catch basin near the inlet of the existing 30-inch pipe and replacing the 30-inch pipe upstream of the structure with a 12-inch pipe or whatever size is needed to pass 5 cfs. 10. I asked that WSDOT staff update/supplement their wetland delineation mapping and reports for the SR-167 work, including the channel between East Valley Road and the 84-inch culvert at SW 23rd Street. The updated report could include a wetland impact analysis of the proposed project elements and also identify proposed wetland mitigation measures. Since no permanent wetland loss is anticipated, the wetland mitigation would be focus on restoration and enhancement measures for areas disturbed by construction activities. The City uses the 1987 delineation methodology. 11. I agreed that I would provide a list of drawings needed for the Corps of Engineers permit applications. The drawings would at least include: • grading plans • restoration plan for wetland areas impacted by construction • details on the proposed control structure at SW 23rd Street and the diversion structure at Panther Creek • profile of the channel and culvert at SW 23rd Street. I asked that WSDOT begin working on these drawings as soon as possible. If you have any questions,please contact me at 277-5547.

The Draft Plan and EIS is comprised of two volumes. Volume 1 contains the Draft Plan and EIS while Volume 2 includes more detailed technical evaluations, correspondence, and other data that support the information presented in Volume 1. As noted in the Draft Plan and EIS, comments need to be submitted by January 31, 1997. We will also be holding a public meeting on January 16, 1997, to review the proposal and to accept public comment. You are encourage to attend the meeting. I appreciated the opportunity to attend the design team meeting earlier this month. In terms of timing for the preparation of permit drawings for the SR-167 work, I anticipate submitting for the Corps of Engineers Section 404 permit after the comment period for the Draft Plan and EIS has ended. Thus, submittal would likely be in mid to late February 1997. I will contact you early in January 1997 to confirm the timing for permit submittal and to discuss the status and future schedule of the project. I look forward to continuing to work with you. If you have any questions, please contact me at (206)277-5547.

Barben-Price MS 110 R. Winter MS 138 M. Olin MS 44 i�City of Rerpn A Predesign meeting was held on December 4, 1996 for this project. The following is information contained therein: Project Description Scott Woodbury described the overall project improvements that are proposed by the City of Renton in conjunction with this project. Basically, it involves three different scenarios of improvements, one of whicif involved our portion of the project.(See East Side Green River Watershed Project, Final Plan and Environmental Impact Statement) Our project will consist of a flood control weir designed for a 100 year storage level with a 72 inch diameter(or larger), fish-passable, cross culvert to enhance the City of Renton's 23rd Street channel improvements, a low flow inlet structure at a 30 inch diameter cross culvert adjacent to the NB on ramp at 180th, and plugging seven existing 18-24 inch cross culverts. To date the city of Renton has been monitoring storm crest stage gauge information in the Panther creek wetland since March 1994. The design documentation file is being compiled and will be tumed in for review and approval on December 29, 1997. Environmental Permits The City of Renton is responsible for obtaining all permits related to the construction of this project and all impacts due to its construction. Some of the permits that will be sought by the City of Renton are: EIS, JARPA(Corps of Engineers, HPA, DOE cert, Predesign Meeting Minutes December 17, 1997 Page 2 SEPA checklist,NEPA, Doc. CE), Flood, Wetland mitigation(site,plan and monitoring). Corps of Engineers--Six months minimum to obtain, pending the outcome of the EIS. Hydraulic Project Approval—Dewatering and fish passage conditional agreement with the Department of Fisheries. Environmental Impact Statement—Fish Passage--It is addressed in the Final EIS that was approved on September 1997. Water levels are often just below cross culverts in the wetland. The wetland is choked with vegetation. The city of Renton is considering an option to improve the P-9 channel for fish passage in the future. Flood Control& Shoreline—The city of Renton will waive these permits as this is their project. Wetland Mitigation--It was discused that wetland mitigation for our work in the Panther creek wetland would be part of an overall mitigation plan that is to address total impacts to wetland for the entire City of Renton stormwater improvement project. Impacts on SR 167--15th St. SW to N. Grady Way, Stage 3 and Stage I projects-- consideration will be gtiven to the drainage and environmental concerns as designed in these two projects. Hydraulics See attached letter from Bob Winters. Landscape Design The city of Renton would like for our project to reconstruct the channel between SR 167 and East Valley Highway. Landscape will prepare a plan to reestablish the channel and mitigate for the wetland impacts. The city of Renton will cover the total cost of this channel reconstruction through a Local Agency agreement. Utilities Olympic Pipeline has two crossings in the vicinity of the new culvert construction. The 18 and 24 inch diameter lines contain jet fuel and are four feet below the existing ground level. Seattle Water has a 60 inch diameter line buried adjacent to East Valley highway. Preliminary review of these utilities indicates there will be no conflicts. Construction easements will be obtained from Olympic Pipeline and an adjacent property.owner. We will coordinate with Seattle Water to resolve potential conflicts. Predesign Meeting Minutes December 17, 1997 Page 3 Maintenance Maintenance was concerned about plugging seven existing cross culverts. They felt that we should use gravel to plug the ends in the event that the cross culverts would be needed in the future. A Local Agency agreement will turnover the maintenance of the new culvert and weir control structure to the City of Renton. Funding The construction budget approved for this project is $421,000. Preliminary estimates, which include substantial traffic control for open cut construction, is $780,000. Consideration will be given to alternate, less costly solutions. Schedule The schedule for this project is as follows: PS&E turn in January 26, 1998 Ad date April 6, 1998 This schedule was delayed one year after the predesign meeting was held in December 1996. The optimum time for this project to be constructed in the Panther Creek wetland is August to October. Due to environmental permitting issues with the City of Renton, this project was not prepared in time for the construction season for 1997. Predesign Meeting Minutes approved as written: J. .

Include me in the mailing list for minutes. An hydraulic report for the 72 inch culvert will be required. Include size justification and a gradient of the channel on both sides as well as design allowances for permit provisions. These may involve fish passage as well as wetland management issues, and several alternatives may be required to address anticipated requirements. Please also include a detail of the inlet as related to embankment for the pipeline access road.

Grady Way Culvert Replacement Dear Mr. Woodbury: This letter is to inform you of the current status of this project and to discuss the coordination that is required to meet the project schedule. Currently we are reviewing the hydraulic assessment of this basin and how best to define and construct the conveyance structure. Our first coordination meeting was held November 18, 1996 with Hydraulics and Environmental. The Pre-design meeting will be scheduled in December after preliminary discussions with other support groups within W SDOT. Our proposed schedule for meeting the Ad date is as follows: Pre-design meeting(tentative) 12/04/96 Constructibility Review Meeting 01/13/97 Begin PS&E concurrent review 01/27/97 Roundtable Meeting 03/12/97 Ad date 04/07/97 We are confident that we will meet our target turn in date of January 27, 1997. As this is a sensitive area to the City of Renton, Army Corps of Engineers and the Department of Fisheries, Wildlife and Ecology, we feel that permits required for this project are a critical part of its successful completion. We are aware of the need and fully intend to cooperate with your efforts to obtain all the necessary permits, temporary construction and permanent access easements. As we mentioned in the past, it is imperative that we meet the current schedule to guarantee funding for this project. We are ready to work with the city to achieve this. Subject: OL2836 SR 167 November 25, 1996 Page 2 We will be notifying your office of the exact date of the pre-design meeting and subsequent design decision meetings by mail.

Under this alternative, flooding would continue along SW 43rd Street in the vicinity of Lind Avenue as well as along the East Valley Road south of SW 23rd Street. These problems would occur even if Springbrook Creek water levels are lowered under either SC2 or SC3 and the water levels along the SW 23rd Street drainage channel are lowered under 23ST2 or 23ST3. If no actions are taken, these problems would become more severe and occur at a greater frequency as the watershed continues to develop. Water Quality. Under PS1 there would be no immediate impact to water quality. Water quality problems related to flooding would continue to occur. 5.3.5.2 Pipe System Improvements Alternative 2 (PS2) - Pipe System Improvements Water Quantity. This alternative, in combination with other Springbrook Creek and SW 23rd Street drainage channel improvement alternatives, would correct existing and projected future flooding problems. Water Quality SW 43rd Street System Improvement (PS2-1). The larger storm drainage pipelines would reduce flooding and associated roadway pollutants (suspended solids, petroleum hydrocarbons, and metals). There is potential for erosion of soils exposed during construction,but if construction is completed during the dry season,there should be minimal adverse impacts to water quality. An HPA from WDFW and a Temporary Modification of Water Quality Criteria permit from DOE may be required for the construction of the outfall pipe at the stream. East Valley Road System Improvements (PS2-2). Same as PS2-1. Rolling Hills Culvert (PS2-3). Removing the existing Rolling Hills culvert and restoring a channel could result in a temporary increase in suspended solids and turbidity downstream. Construction activities in Rolling Hills Creek would require an HPA from WDFW and a Temporary Modification of Water Quality Criteria from DOE. These permits would likely require the use of certain best management practices to limit erosion and sedimentation, and allow construction only during a summer construction window when flow and impacts would be minimal. 5.4 MITIGATION MEASURES Design and analysis of conveyance improvements would have to be consistent with the requirements of the King County Surface Water Design Manual (King County Department 11/12/96e JSA 5-13 CHAPTER 5 of Public Works 1990) Chapters 3,4, and 5 as adopted by the City of Renton (Title IV, City of Renton Building Regulations, Chapter 22) and other City, state, and federal regulations for work within streams, floodplains, and shoreline areas. Many'improvements will be within areas designated as shorelines of the state and therefore are subject to the City's Shoreline Master Program requirements (Title IV, City of Renton Building Regulations, Chapter 19); these improvements will require a Shoreline Substantial Development Permit. Mitigation measures for water quality include the following. 5.4.1 REQUIRED MITIGATION ■ Short-term and long-term soil erosion shall be minimized through implementation of best management practices and the provisions set forth in the City of Renton Standard Specifications for Municipal Construction,and in the King County Surface Water Design Manual (King County Department of Public Works 1990) adopted by the City of Renton Storm and Surface Water Drainage Ordinance (Title IV, City of Renton Building Regulations, Chapter 22). This includes submittal of plans detailing temporary and permanent erosion-control measures, revegetation plans, plans for handling surface and subsurface water during construction, and a schedule for all phases of construction. ■ Vegetation clearing and earthwork shall be subject to the regulations of the Land Clearing and Tree Cutting Ordinance and the Mining, Excavation, and Grading Ordinance (Title IV, City of Renton Building Regulations, Chapters 9 and 10). ■ The Washington State Hydraulic Code Rules regarding conduit crossings and other instream work (Chapter 220-110 WAC) require that ". . . alteration and disturbance of the banks and bank vegetation shall be limited to that necessary to construct the project. All disturbed areas shall be protected from erosion within 7 days of completion of the project using vegetation or other means." In addition, a construction window would be established by the WDFW for work in streams, likely June 15 to September 15. ■ Construction activities that may temporarily violate state water quality criteria typically require a Temporary Modification of Water Quality Criteria permit from DOE (RCW 90.48; WAC 173-201 and 173-222). Permit conditions may include periodic monitoring of water quality upstream and downstream of the construction activity for constituents such as dissolved oxygen and turbidity. 5.4.2 OTHER MITIGATION ■ Detailed maintenance plans will be developed during design and permitting of each project element so that regular maintenance activities, if needed, are agreed upon and recognized as part and parcel of the project for it to function as intended throughout its life. ■ The time of disturbance is to be kept to a minimum. 5-14 JSA 11/12/96e lNr"wA- SURFACE WATER QUANTITY/QUALITY DkAFr ■ Plant fast-growing shrubs and trees and revegetate streambanks immediately following construction. ■ If necessary, dewatering plans are to include measures for decreasing the iron loading in the discharge water, such as settling ponds and/or filtration. 0 �r vises ■ Do not use inwater excavation (dredging) unless it cannot be voided or the potential for discharging sediment-laden water into the downstream stem is minimal and the dredging activity is allowed by state and federal permits. Flows will be temporarily bypassed around the instream construction using a pump or gravity system, using fish- screening devices as appropriate. Plans for handling surface water will be required prior to beginning construction (see required mitigation for short-term and long-term erosion above). ■ See the "Mitigation Measures" section of Chapter 7 of the EIS for additional mitigation measures. 5.5 SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS If no action is taken, flooding will continue to become more severe as the area of impervious surfaces in the watershed increases with development. 5.6 CITATIONS DOE.

SFr TERRESTRIAL AND AQUATIC RESOURCES levels would be short-lived and would occur during the dormant period for vegetation, so plant communities are not expected to change significantly. Fish. Provided Rolling Hills Creek supports no fish,this alternative would have a negligible impact on fish populations in the system. Should Rolling Hills Creek support rearing salmonids in the future, then entrainment into Wetland 7N might occur during storm events (greater than a 2-year event) with a subsequent loss of fish. By increasing flood storage and decreasing flooding, the impacts of flood-related bank erosion and fish stranding in flooded areas would be reduced. All culvert replacements would be subject to approval by the WDFW in the form of a Hydraulic Project Approval (HPA) permit. 7.3.5 PIPE SYSTEM IMPROVEMENTS 7.3.5.1 Pipe System Improvements Alternative 1 (PSI) - No Action Vegetation and Wildlife. Plant and animal communities would continue to be influenced by seasonal flooding. This alternative would not directly alter these communities significantly. Fish. PSl would have little or no direct impact on fish or the in-stream environment. 7.3.5.2 Pipe System Improvements Alternative 2 (PS2) - Pipe System Improvements Vegetation and Wildlife. Vegetation would be temporarily disturbed as existing pipe systems are replaced, then reestablished following pipe replacement. Removal of the Rolling Hills culvert would allow the stream channel to be restored to a more natural environment, providing a long-term benefit to native plants and animals. Habitat plantings and occasional maintenance would help to improve the restoration success of the stream channel. Fish. The proposed improvements would have little or no direct impact on fish or in- stream habitat except for removal of the Rolling Hills Creek culvert that would return this portion of the stream to a more natural state, thus increasing its habitat value and facilitating fish passage into Rolling Hills Creek. However, the pipe system improvements would result in a reduction in the incidence of flooding and corresponding water quality problems associated with surface ponding of industrial areas. 7.4 MITIGATION MEASURES The following mitigation measures include those required by code. Other mitigation measures are defined that could be required as part of the City's formal environmental review process. u/ia/%e JSA 7-17 CHAPTER 7 /NfiA"At, 59APA4r 7.4.1 REQUIRED MITIGATION ■ The PC2 high flow diversion structure would have to be approved by the WDFW through an HPA permit. During the design phase, determine the need for a fish exclusion device. ■ Vegetation clearing and earthwork shall be subject to the regulations of the Land Clearing and Tree Cutting Ordinance and the Mining, Excavation, and Grading Ordinance (Title IV, City of Renton Building Regulations, Chapters 9 and 10). ■ All in-stream alternatives will be required to comply with Washington State Hydraulic Code Rules (Chapter 220-110 WAC) and HPA permit conditions. Requirements could include: - bypassing flows around and isolating work areas during construction; - limiting construction to a summer construction window when flow is low and anadromous fish are not present; - utilizing other erosion control best management practices; - not stockpiling any material waterward of the ordinary high water line; - taking care not to leave any depressions where fish could be stranded with changing water levels; and - utilizing proper design for fish passage. 7.4.2 OTHER MITIGATION ■ Develop a revegetation plan during the design phase that includes use of riparian vegetation and construction of habitat improvement features such as nest boxes and perch poles. Coordinate with adjacent property owners regarding compatibility with adjacent, existing landscaping schemes. ■ Where feasible, limit channel modifications to a single bank in any segment and incorporate existing beneficial vegetation into the new channel design; where feasible, minimize disturbance to the low flow channel while enhancing vegetation and in-stream habitat. ■ The new SR-167 culvert at SW 23rd Street and inlet control structure could be designed to include vertical drop on the control weir or other physical means (such as series of weirs) to add oxygen to the water as it leaves the Panther Creek Wetland and flows through the culvert. The culvert will not be designed to provide for future fish passage for the reasons outlined in this chapter, in the ESGRWP Plan, and in the Volume 2 technical memoranda. 7-18 JSA a/is/ TERRESTRIAL AND AQUATIC RESOURCES ■ Under PC2, the Panther Creek diversion structure could be designed to include physical means (such as series of weirs) to add oxygen to the water as it is diverted into the Panther Creek Wetland. ■ See mitigation in Chapter 5 of the EIS for additional measures to minimize or mitigate potential impacts to fish. ■ Implement Washington Department of Ecology guidelines for the control of invasive species. ■ The riparian planting could include the use of a temporary irrigation system to ensure that the planted vegetation becomes adequately established during the first 2 years following construction. ■ Similar to requirements for wetlands, monitoring and maintenance of other plantings not in wetlands will be conducted to ensure that plant establishment and survival rates achieve desired performance goals. Since the improvements will be City owned, stewardship of the plantings would continue for the 5 years and beyond. As noted in the project element descriptions, periodic maintenance removal of vegetation may be necessary, the frequency and scope of which depends upon which alternatives are selected (i.e., SC2 or SC3). ■ Work with WDFW to evaluate the feasibility and applicability of using a seasonal water level control structure (i.e., fish passable weir) in Springbrook Creek downstream of the wetland mitigation site, possibly at the SW 34th Street road crossing. An in-stream control structure could potentially help to address the following: (1) The lack of fish-rearing habitat in lower Springbrook Creek. (2) The frequent and high water level fluctuations in Springbrook Creek. (3) Possibly help achieve a project goal of designing for sedimentation to occur at defined locations where suitable. Such a structure could: (4�Z(i) Create fish-rearing habitat by raising water levels at the control structure 1 to 2 feet to create a seasonal in-stream pool from the control structure to the Oakesdale Avenue crossing and an off-channel pool in the wetland mitigation bank. \'1 (2) Possibly encourage coarse sediment to settle out in the channel reach downstream of Oakesdale Avenue to the railroad bridge at SW 40th Street; sediments could then be easily removed by equipment on Oakesdale Avenue which lies adjacent and parallel to the reach. u/ia/vice JSA 7-19 CHAPTER 7 11viiANA1- OQAf-r (4 (3) Increase the potential for amphibian breeding in the wetland mitigation bank site because water levels would tend to fluctuate less frequently and not as severely. C�l A11- Increase the potential for success of plant species that are sensitive to high water fluctuations. 7.5 SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS Assuming mitigation, no significant unavoidable adverse impacts on terrestrial and aquatic resources would occur under any of the proposed alternatives. 7.6 CITATIONS Beak Consultants, Inc. 1990.

We look forward to working closely with you and other WSDOT staff to accomplish construction of the culvert next summer. It is our belief that the necessary environmental reviews and permitting we are conducting can be completed in time to meet this schedule. In our recent telephone conversation, you indicated that the funds WSDOT has budgeted for the project must be encumbered before the end of your fiscal year in June 1997, or they may be turned back for reallocation to other programs. I would like to discuss the potential of entering into an interlocal agreement to encumber the funds budgeted for this project, so that if we are slightly delayed from meeting the June deadline, the funds have already been encumbered and will not be turned back. I appreciate your assistance. If you have any questions,please contract me at(206)277-5547.

Many of these culverts are filled in and/or only partially functioning. The ones that are functioning are submerged most of the year. Access for maintaining these culverts is difficult because the culverts are 15 to 20 feet below the elevation of SR-167 and are separated from the road by a guard rail. Maintenance of the SR-167 culverts is the responsibility of the Washington State Department of Transportation(WSDOT). This project proposes plugging the poorly functioning SR-167 culverts between the southernmost culverts (carrying Panther Creek near Nendels Hotel) and SW 23rd Street and replacing these culverts with a new SR-167 crossing at SW 23rd Street. This replacement would result in a total of three outlets across SR-167 between I-405 and SW 43rd Street: the new SR-167 culvert crossing at SW 23rd Street, the southerly crossing carrying Panther Creek, and the existing 3-foot by 4-foot box culvert outlet located near I-405 that conveys Rolling Hills Creek. A schematic plan and profile of two options for the new SR-167 culvert at SW 23rd Street and the SW 23rd Street drainage channel downstream of the culvert are attached as Figures 8.7 and 8.8 from the preliminary draft East Side Green River Watershed Project(ESGRWP)Plan by R. W. Beck. As far as WSDOT involvement is concerned, the construction of a new culvert crossing of SR-167 at SW 23rd Street includes the following components: • New SR-167 culvert; • Plugging existing SR-167 culverts; • Inlet control weir; and • Outlet channel. Each of these elements are described in more detail following: 1. New SR-167 culvert The new culvert crossing under SR-167 at SW 23rd Street would provide a new outlet from the Panther Creek Wetland (PCW) to act as a replacement for the series of poorly or non-functioning crossings to be plugged. In terms of capacity, the culvert should be 72 inches in diameter according to an analysis by R. W. Beck. However, if this culvert needs to be designed for fish passage, it would need to be larger to allow partial burial of the culvert bottom. In an agency meeting of May 18, 1995, the agencies stated they would like the project to achieve both fish passage and rearing habitat improvements where possible. In a separate meeting with the Corps of Engineers (COE) on May 25, 1995, the COE suggested that the proposed culvert at SW 23rd Street provide for fish passage, even if fish are not allowed into the wetland until some time in the future. In this way, if the culvert were designed for fish passage, it would be low enough so as not to preclude construction of a fish passage channel through the wetland at some future time. Installing the culvert at a lower elevation will add to the cost because of the increased length required to daylight the culvert beyond the fill slope of SR-167. There are problems associated with providing fish passage through this structure in the future because passage further upstream would not be possible through the Panther Creek Wetland, Culvert Crossing SR-167 in the Vicinity of SW 23rd Street Page 2 unless an excavated channel was constructed and maintained. Under current environmental regulations, an excavated channel through the wetland would likely not be permitted due to potential wetland impacts. Also, the channel would likely fill in with vegetation and become a significant maintenance problem. In addition, numerous other fish passage and habitat problems (e.g., alluvial fan and low base flows) severely limit the potential for Panther Creek to provide passage to upstream migrating salmonids. The issue of whether the culvert should be designed to allow fish passage in the future will be resolved through the EIS process. 2. Plugging existing SR-167 culverts The preferred approach is to close all of the culverts because they are difficult to access and visually inspect. Also, the flow through the culverts is a contributor to the flooding problems in East Valley Road (EVR). However, if closing the culverts would be considered an impact that requires expensive mitigation, an optional approach is for one of the SR-167 cross culverts (located at about SW 29th Street) to remain operational. All other cross culverts would be closed and this culvert fitted with an intake restrictor that limits flow during flood events, but would permit flow to pass freely through the culvert during the dry summer months. This restrictor would prevent high flows from draining across SR-167, through the existing ditch at about SW 29th Street, and into the East Valley Road system. Instead, the high flows would pass through the proposed culvert at SW 23rd Street and into the SW 23rd Street channel system. By using this approach, impacts to the SR-167 west ditch wetlands could be avoided. However, the preferred action is to close all culverts but the culvert carrying Rolling Hills Creek, the southernmost culvert(s)carrying Panther Creek,and the new culvert at SW 23rd Street. 3. Inlet control weir The new culvert installation would include an adjustable weir at its inlet that could allow seasonal or intermittent adjustment of the PCW water levels for purposes such as control of mosquito larvae or invasive vegetation. Use of a constant weir elevation is proposed for this project, but the culvert inlet structure should be constructed so as to not preclude the ability to adjust wetland water levels if the necessary permits and approvals for doing so are obtained through a future, separate project proposal. For hydraulic modeling of flood simulations, the flood control weir elevation was set at 12.5 feet (Datum NGVD 1929) to simulate an initial water level in the wetland consistent with wet season water levels measured at City wetland crest stage gages #2 and #3. This elevation was selected to somewhat conservatively model the wetland with some of its storage already filled and unavailable to attenuate flows. However, the simulated weir elevation is about 2.5 feet above the elevation of the existing outlet ditch for the PCW that is located on the west side of SR-167 at about SW 29th Street. Therefore, a V-notch or small diameter orifice will be used below the flood control weir to replace the function of the existing outlet ditch in passing low flows to the downstream system. The size and configuration of the V-notch or orifice will be determined in final design. Setting the flood control weir or low flow outlet below the existing outlet is not considered an option because of potential environmental impacts associated with significant reductions in wetland hydrology, i.e., loss of wetland area, changes in habitat, and others. Additionally, the width of the weir was sized so that 100-year future condition flood storage is similar to the storage currently being provided in the wetland, thereby maintaining the function of the wetland in attenuating downstream flows. H:DOCS:96-539a:Sw:ps t Culvert Crossing SR-167 in the Vicinity of SW 23rd Street Page 3 4. Outlet channel Channel improvements are needed between the new SR-167 culvert outlet and the two existing culverts to the west under the EVR. There are risers on the inlet side of the EVR culverts that would be removed and a wider, deeper channel constructed between EVR and SR-167 to connect the inverts of the EVR culverts and the new SR-167 culvert. DESIGN CRITERIA Preliminary design data for project elements discussed in the project description are outlined below as needed. All elevations are based on the NGVD 1929 datum. The following is based on information and analysis by R. W. Beck. 1. New SR-167 culvert. Preliminary design data: Upstream I.E. 9.0 feet Downstream I.E. 7.0 feet 100-year flow 107 cfs(simulated) 100-year tailwater elevation 13.3 feet(simulated) 100-year headwater elevation 13.9 feet(simulated) Minimum culvert diameter 72-inches Assumptions and additional information: a. If the culvert is designed to provide future fish passage, then the diameter will likely need to be increased. b. If the culvert is not designed to provide future fish passage, then the invert(s) of the culvert may potentially be raised and the culvert diameter decreased. c. Simulated flows are for future condition land use and are based on frequency analysis of Springbrook Creek inflows at the downstream Black River Pump Station. This is believed to be the "worst case" design scenario as the scaling factors applied to the hydrographs used for hydraulic routing are less for simulations using flows based on frequency analysis of the culvert's tributary subbasins than for simulations using flows based on frequency analysis at the pump station. However, some sensitivity analysis of the culvert should be performed to check its adequacy for a range of flows up to 20% higher than listed in the preliminary design data above. This is needed to test the adequacy of the culvert capacity should the hydrologic analysis be under-predicting flows. 2. Inlet control weir. Preliminary design data: Flood control weir sill I.E. 12.5 feet Flow control weir width 3.5 feet 100-year flow Same as for new culvert 100-year tailwater elevation 13.9 feet(simulated) H:D0CS:96-539a:S W:PS Culvert Crossing SR-167 in the Vicinity of SW 23rd Street Page 4 100-year headwater elevation 16.1 feet(simulated) Low flow orifice I.E. 10.0 feet Low flow orifice size and configuration To be determined during design phase Assumptions and additional information: a. The weir was sized so that 100-year future condition flood storage is similar to the storage currently being provided in the wetland, thereby maintaining the function of the wetland in attenuating downstream flows. The 100-year future conditions flood elevation in the Panther Creek wetland on the east side of SR-167 modeled by R. W. Beck, assuming no drainage improvements, is 17.0 feet. This is 1.0 foot greater than the FEMA 100-year flood elevation in the Panther Creek Wetland, which is based on land use and drainage system conditions at the time of the FEMA analysis(— 1979). b. Low flow orifice LE. is based elevation of the existing low flow outlet at the SW 29th Street ditch(see description). c. The flow control weir width assumes that Panther Creek is diverted into the Panther Creek Wetland to flow out the new SR-167 culvert. Without Panther Creek being diverted, the weir width is slightly reduced to 3.0 feet in order to maintain storage levels in the Panther Creek Wetland similar to current conditions. 3. Outlet channel. Preliminary design data: 100-year flow Same as for new culvert 100-year tailwater elevation 13.3 feet(simulated) 100-year headwater elevation 13.3 feet(simulated) Assumptions and additional information: a. Channel side slopes in the R. W. Beck analysis were assumed to be 3HA V because of the anticipated unstable natural of the surrounding fine grained soils. b. Use of side channel weirs or berms along the channel may be necessary to control water levels in the west SR-167 ditches to the north and south and prevent wetland dewatering. c. The channel may be partially under water under even low flow conditions, depending upon which alternative is implemented for the downstream channel, i.e., whether SW 23rd Street Channel Alternative 2 or 3. Alternative 3 (Figure 8-8 attached) would restore positive drainage along the entire length of the SW 23rd Street channel from SR-167 to Springbrook Creek, eliminating any standing water.

Renton, WA 98055 MEMORANDUM OF UNDERSTANDING: Proposed Culvert Crossing SR 167 in the vicinity of SW 23rd Street Dear Gregg: WSDOT held a meeting on March 8, 1995 to consider the design and scheduling of a proposed culvert crossing SR 167 in the vicinity of SW 23rd St. (P-9 Channel). Attending the meeting were Kristina Tong(Corps of Engineers), Ron Straka and Scott Woodbury (City of Renton) and several representatives of WSDOT (see attached list of attendees). This meeting was prompted by the following circumstances. A recent WSDOT Contract was halted due to a wetland violation. Work now deleted from this contract includes a major culvert crossing SR 167. Wally Hendricks stated this culvert was committed to the City of Renton in lieu of restoration of several existing smaller culverts which are now inoperative. Ron Straka discussed a major drainage study the City of Renton is now conducting in the WSDOT project area. The study may recommend improvements to the P9 Channel to the west of SR 167 (see attached sketch), the proposed culvert crossing SR 167, and future possible diversion of flood waters through the Panther Creek Wetland to the culvert crossing from the east side of SR 167. More studies and further coordination are required with the Corps of Engineers in the planning phase and later permit processing phase. The City expects the study to result in a project to improve drainage across SR 167 from east to west through an open channel which will eliminate existing flooding problems and benefit water quality and aquatic habitat. Kristina Tong asked that there be only one permit requested at the culvert crossing SR 167 and preferably coordinated with City proposals on both sides of SR 167. She recommended minimizing impacts to the aquatic environment. Greg Zimmerman May 24, 1995 Page 2 Conclusion The City of Renton's drainage study and permit applications will take a year or longer to complete. During this time WSDOT will develop, at its sole expense, a separate contract and fund the construction of just the culvert crossing. The City will obtain necessary permits and develop the appropriate schedules at the City's sole expense. In that way the permit processing and contract development for the end to end facility will be orderly and the construction schedule precisely controlled. To make sure this is a proper representation of our consensus approach, a copy of this letter is going to the Corps of Engineers and we would appreciate a signature of concurrence from the City of Renton. A returned copy of this letter with a signature below may be the most effective approach. Thanks again for the participation of the City of Renton and Corps of Engineers Staff in the March 8 meeting.

Dear Mr. Johnson: In follow up to your December 14, 1993 letter, we met with Brian Holling and Bill McKees on January 13, 1994 to discuss the existing and proposed culvert crossings from the Panther Creek Wetland. WSDOT construction plans include abandoning several existing culvert crossings draining from the Panther Creek Wetland and constructing two twin 54" replacement culverts at the location of the future P-9 channel crossing. In the meeting we commented that the culvert sizing appears adequate in combination with the existing culverts that are to remain open. We also suggested design inlet and outlet elevations for the 54" culverts of approximately 1 1.0 and 10.0, respectively (1929 NGVD datum). These elevations are two feet higher than the WSDOT proposed elevations, and may be more appropriate considering surrounding existing grades. According to a 1962 aerial survey, a copy of which we transmitted to Brian following the meeting, the existing ground elevation in the Panther Creek Wetland at the P-9 crossing is approximately 11 feet (1929 NGVD datum). You should be aware that while these comments reflect our observations concerning the location, size, and elevation of the new P-9 channel culverts, we do not certify the adequacy of the design. WSDOT and its contractors are solely responsible for the final culvert design configuration and the environmental impacts associated their construction. We also expressed our concern in the January 13, 1994 meeting that the WSDOT plans do not include upsizing the Springbrook Creek culvert crossing at South 192nd Street in Kent, WA. We had requested in the attached July 30, 1991 letter that this culvert crossing be upsized according to criteria recommended in the letter in order to provide greater flood conveyance capacity, reduced sediment accumulation, and improved fish passage. We wish to reemphasize the need for the culvert improvement and request that WSDOT reconsider its importance and include its construction as part of the HOV project. At your request we will be available to provide any additional information, review the culvert design, and assist in its permitting. 200 Mill Avenue South - Renton, Washington 98055 TIi IS PAPER CONIANS 509<.RECYCLED MATERIAL,I0 POST CONSUMER Washington State Department of Transportation Crossings at Panther Creek Wetland and Springbrook Creek Page 2 We would appreciate WSDOT informing us early of any new proposal or changes in work that affects the City of Renton so that we can work together to reach a solution.

Paul Prochaska, P.E., Vice President CTS Engineers, Inc. 2115 - 1 12th Avenue NE - Suite 100 Bellevue, WA 98004 SUBJECT: CITY OF RENTON DRAINAGE REVIEW OF SR-167 HOV PROJECT Dear Mr. Prochaska: The City of Renton appreciates having the opportunity to review the Washington State Department of Transportation (WSDOT) SR-167 HOV projects preliminary hydraulic report, along with meeting with you to discuss our drainage concerns related to the project. At this time, we want to formalize our review comments and the topics of our discussions during the June 20, 1991 meeting, and to provide you with flow information for the Springbrook Creek crossing of SR-167 and the proposed P-9 Channel/Panther Creek Wetland SR-167 crossing control structure as we discussed. The City has recenty obtained preliminary finds from a hydrologic model prepared for us f by Northwest Hydraulic Consultants for the East Side Green River Watershed Plan using the HSPF (Hydrologic Simulation Program-FORTRAN) model. The existing drainage systems under SR-167 include a series of 12-inch to 30-inch crossing culverts under SR-167 which carry the flows from the Panther Creek Wetlands and Panther Creek to a unmaintained ditch on the west side of SR- 167. This condition has resulted in significant flooding problems, especially in the vicinity just north of SW 43rd Street. This runoff from the Panther Creek Wetlands and Panther Creek then enters City storm systems which directly outlet into Springbrook ` Creek. Improvements to the existing ditch along the westerly side of SR-167 could [ provide improved water quality benefits and possibly improve the local drainage problems in the vicinity described earlier. The City of Renton requests that the proposed P-9 Channel/Panther Creek Wetlands culvert under crossing of SR-167 be constructed as an important component of the SR- { 167 HOV project. This facility has been identified as part of the United States Department of Agriculture Soil Conservation Service and City of Renton East Side Green River Watershed Plan since the early seventies. This would provide a defined Paul Prochaska a CTS Engineers, Inc. Page 2 drainage path that would allow hydrologic and wildlife corridor connection of Panther Creek and the Panther Creek Wetlands with Springbrook Creek which would allow fish passage small mammal immigration from Springbrook Creek to Panther Creek. ' Based on the HSPF model, the design flows for the 2, 10, 25, 50, and 100-year flood frequency from the Panther Creek Wetlands through the proposed P-9 Channel control culvert crossing of SR-167 is estimated to be 161 , 227, 264, 294, and 326 cfs respectively by Northwest Hydraulic Consultants with the HSPF model. The P-9 culvert should be designed to meet the King County Surface Water Design Manual (KCSWDM) requirements for capacity and fish passage using those flows and accounting for the effects of a maximum upstream and downstream water surface elevations (for 10 year flows and greater) of 16.0 and 14.5 NGVD respectively. Additional information regarding the P-9 Channel/Panther Creek Wetlands project can be reviewed in the projects Draft Interim Preliminary Engineering Report prepared by R. W. Beck and Associates for the City of Renton, which has been previously supplied to Alpha Engineers. The City also requests that the Springbrook Creek culvert crossing of SR-167 at South ' 192nd Street be improved for flood peak conveyance and sediment management, and has plugged several times during recent major storm events. This culvert crossing is a maintenance problem for both WSDOT and City of Renton maintenance crews, and has resulted in the stream diverting and flowing to the north along the easterly side of SR- 167 to the next crossing culvert which flows into a ditch on the west side of SR-167 in the City of Kent corporate limits. This ditch then flows to the north and enters a ' limited capacity storm system in SW 43rd Street that flows westerly to Springbrook Creek. This occurred on April 4, 1991 flooding of SW 43rd Street to depths of two to three feet. This condition jeopardizes public safety and we request that the Springbrook Creek culvert crossing of SR-167 at South 192nd Street be analyzed and a solution developed which eliminates this condition from recurring and keeps the stream in its natural drainage course and could even improve fish passage. Based on the HSPF model, the design flows for the 2, 10, 25, 50, and 100-year flood frequency flows of the Springbrook Creek crossing of SR-167 at South 192nd Street I are estimated to be 43, 65, 78, 88, and 98 cfs respectively. The culvert crossing should be sized to accommodate these flows with the appropriate factor of safety and consideration given to sediment deposition into the system, fish passage, and entrance I geometry as prescribed by the KCSWDM. This crossing culvert should be reviewed for placement on a more frequent maintenance schedule. I We recommend that the existing and proposed storm and surface water systems analyzed and designed as part of the SR-167 HOV project be performed to meet the requirement contained with the KCSWDM.

Offsite flow volumes included in the calculations were taken from a Hydrologic Simulation Program- FORTRAN (HSPF) model prepared by Northwest Hydraulic Consultants for the City of Renton!s Eastside Green River Watershed Plan. Because we were unable to coordinate our construction with the future improvements to the P-9 Channel, an interim solution was adopted. This solution is to install the twin cross culverts in the vicinity of the future P-9 channel and to abandon several existing cross culverts. Referred to in the attached text, these culverts; SD 305, 306, 307, 308, 310 and 311 are currently not functional. An existing 48 inch diameter cross culvert, referred to as SD309 will continue to be used after cleaning. Please review this data and advise our Construction Project Office of any adjustments in the selected elevations of these twin culverts. If you have any questions, please call Brian Holling at 440-4566. Sincere , Jo E. Johnson, PE Project Engineer BKH:bh cc: Bill McKees file t flood areas. Since this happens only intermittently, it will be best to see the drainage plans for specific locations. The widening of the following ramp will also encroach into the existing flood areas: S . 212th Street Interchange EW-S Ramp P-1 Channel Flood Plain Channel Changes There are no channels located in Section 3 of this project. Culverts The City of Renton also proposes a single outlet out of Panther Creek Wetland. R. W. Beck and Assoc. has completed Panther Creek Wetland/P-9 Channel Design Draft Interim Preliminary Engineering Report which is part of the Eastside Green River Watershed Plan. Further work on this report has been discontinued. As can be seen from the correspondence with the City of Renton enclosed in the Appendix, the original idea of the City was to provide details of the SR167 culvert to be tied into the proposed P-9 channel to WSDOT in time so this culvert could be installed as a part of the SR167 HOV Improvements while the City of Renton would make concessions to some of its requirements related to the detention of storm water. In other words WSDOT would build the culvert and the City of Renton would forego requirements for the detention. The letter from the City of Renton to CTS dated July 30, 1991 indicates that the City also meant for WSDOT to design this culvert. To-date there has been no agreement reached between the City of Renton and WSDOT on the subject of the Panther Creek Wetland culvert. The problem at Panther Creek Wetland can be summarized as follows: SR167 was built in the late 60's and early 70' s and the Panther Creek Wetland was drained across the freeway by a series of culverts of different diameter. Each culvert drained into an open channel (ditch) running west from SR167 to Springbrook Creek. As the land use rapidly changed from agricultural to industrial, the land owners adjacent to SR167 started to fill in their lots obliterating most of the ditches and in turn causing a sediment to build up in the culverts which had nowhere to drain. Alpha Engineering Group survey crew inspected these culverts in December 1992 in order to provide up-to-date information about their condition. This information is presented here and also elsewhere in this report. 34 ' f , Culvert I .E. In I.E. Out Condition Dia. SD 305 11 . 49 10 .87 Plugged 12" SD 306 9 .33 9 .03 Plugged 36" SD 307 8. 17 ?

Clean 24" f Looking at this information we can see that the Panther Creek Wetland is now practically being drained only by SD 308, SD 309, and SD 311 . SD 308 is clean probably because it sits higher than others and SD 311 is in comparison with others rather small. Out of these seven culverts only SD 309 has somewhat positive drainage due west via open channel OC46 as shown on Sheet 45 . Open Channel OC46 runs west toward East Valley Road where it enters grate inlet at el. 13 . 04. Grate inlet is connected to 18" dia. conc. pipe which in turn is connected to 41x21 box culvert crossing East Valley Road tied into closed pipe system built circa 1981 and running north to P-9 ditch (P-9 Channel is not built yet) . Inv. elevations of 18" dia. pipe and box culvert are not known. In absence of an agreement between the City of Renton and WSDOT, the City decided to add detention requirements to the part of the project within their jurisdiction. Several 1 solutions for the Panther Creek Wetland drainage were considered and discarded. 1 . To construct a bridge or a large culvert at the proposed P-9 Channel location would be costly and it would disrupt the traffic. 2. To construct a channel along the west side of the SR 167 and intercept all of the existing culverts and simultaneously provide biofiltration and detention would result in a need for additional right-of-way due to large cross-section required. 35 3. To construct a closed pipe system intercepting all of the culverts and providing the detention would result in installation of a 8-foot diameter pipe for 4460 feet. The biofiltration swale could be then installed parallel to the SR 167. The cost of the pipe system would be very high. These three solutions have one disadvantage and that is that the total flow is brought to a single point at the proposed P-9 Channel location and the only items in place from the proposed system are two 48-inch diameter pipes under East Valley Road. The remaining major part of the P-9 Channel must as yet be built. The three solutions would cause flooding between SR 167 and East Valley Road at the proposed P-9 Channel location. The one solution proposed as an interim solution and also 4 presented in this Hydraulic Report involves capping off SD 1 305, SD 306, SD 307, SD 308, SD 310 and SD 311 . These culverts with exception of SD 308 and SD 311 are plugged with sediments and debris and do not presently work anyway. SD 309 will be cleaned and the open channel OC46 with the inlet at the East Valley Road will be improved. Ditch elevations of 12. 0 shown on Sheet 45 are based on assumption that OC46, grate inlet and 18" dia. pipe will be revised below el. 12.0 and thus improve drainage west of SR 167. To compensate for the plugged culverts, we propose installation of two 48" diameter culverts crossing SR 167 at the future P-9 Channel location. These two culverts may be retained or replaced with the final P-9 .Channel structure crossing under I SR 167 in the future. The summary of remaining culverts in Section 3 is as follows. The culverts carrying flow of Garrison Creek and 1 Springbrook Creek across SR 167 will remain unchanged. t There are no proposed interchange or private road culverts. The following culverts will remain as outfalls: SD 265, SD ' 267, SD 269, SD 329, SD 275, SD 278, SD 279, SD 282, SD 381 , SD 294, SD 297, SD 302, SD 303, SD 309, SD 511 and SD 513 . The following culverts will be intercepted by the proposed i biofiltration ditches : SD271 , SD280, SD281 , SD283, SD284, SD285, SD287, SD289, SD291 , SD292, SD293 and SD347. ` I The following culverts serving as outlets from Panther Creek Wetland will be abandoned: SD305, SD306, SD307, SD308, SD310, SD311 , and SD410 . Culvert End Sections 36 t i i There are no storm or sanitary sewers belonging to other jurisdictions which will be affected by this project. Gutter Design Concrete curb and gutter will not be used in Section 3 of this project.

Detention Detention in Section 3 inside the City of Kent limits will be provided by detaining water in biofiltration swales or detention pipes using 25-year post-development storm flow with 10-year storm pre-development release. Within the City of Renton the detention means will be biofiltration swales, detention vaults or detention pipes using 10-year storm postdevelopment flow with 2-year storm predevelopment flow release. The flow control structures (FCS) are proposed at the following locations: t Sta. 909+10 LT Sta. 916+00 LT Sta. 935+15 LT Sta. 960+00 RT Sta. 968+90 LT Sta. 969+10 LT Sta. 974+50 LT Sta. 974+70 LT Sta. 993+90 LT Sta. 997+15 LT Sta. 1000+40 LT Sta. 1017+85 LT Sta. 1018+15 LT Sta. 1029+85 LT Sta. 1041+55 LT Sta. 1041 +85 LT Sta. 1049+75 LT AL2 56+75 LT Sta. 1064+50 RT �o Sta. 1071 +00 LT Sta. 1101 +50 LT Sta. 1102+50 LT Sta. 1120+60 LT Sta. 1121 +40 LT j No retention ponds are proposed for Section 3 . I Due to the lack of space to construct detention facilities along the east side of SR 167 and due to the large tributary areas off the project site draining to this side we have not detained any runoff generated east of the SR 167 centerline. To compensate for the undetained runoff from increased impervious surface of northbound lanes, we propose to limit the flow from the southbound lanes so that the total runoff I equals the pre-development stage. To do so will require large detention volumes to be provided in the ditches along the southbound lanes. Normally this would be accomplished by calculating pre- development 10-year storm runoff at outfall locations and 1 then providing such detention volume for southbound lanes generated runoff for post-development 25-year storm as to result in the same flow at the outfall as for pre-developed I conditions . 1 To expedite our calculations we looked at the possibility of calculating the detention necessary to limit the runoff from the west part of the SR 167 to the flow from pre-development conditions for 2-year storm. In order to prove that this approach is valid we have chosen a specific area for which we have calculated required detention volume based on the normal approach to detain flow from post-development impervious surface for both northbound and southbound lanes. This specific area is on Sheet 40 and the outfall is SD291 . Then we calculated detention volume needed to limit flow from the southbound lanes only to 2- year storm pre-development runoff as a shortcut method. The shortcut method has given us larger detention volumes and therefore we used it to size the ditches along the southbound lanes of SR 167 in the City of Kent limits of ISection 3 . The above mentioned calculation follow this page.

Paul Prochaska, P.E., Vice President CTS Engineers, Inc. 2115 - 112th Avenue NE - Suite 100 Bellevue, WA 98004 SUBJECT: CITY OF RENTON DRAINAGE REVIEW OF SR-167 HOV PROJECT ` I Dear Mr. Prochaska: The City of Renton appreciates having the opportunity to review the Washington State Department of Transportation (WSDOT) SR-167 HOV projects preliminary hydraulic report, along with meeting with you to discuss our drainage concerns related to the project. At this time, we want to formalize our review comments and the topics of our discussions during the June 20, 1991 meeting, and to provide you with flow information for the Springbrook Creek crossing of SR-167 and the proposed P-9 Channel/Panther Creek Wetland SR-167 crossing control structure as we discussed. The City has recenty obtained preliminary finds from a hydrologic model prepared for us by Northwest Hydraulic Consultants for the East Side Green River Watershed Plan using the HSPF (Hydrologic Simulation Program-FORTRAN) model. The existing drainage systems under SR-167 include a series of 12-inch to 30-inch crossing culverts under SR-167 which carry the flows from the P-3rther Creek Wetlands and Panther Creek to a unmaintained ditch on the west side of SR- 167. This condition has resulted in significant flooding problems, especially in the vicinity just north of SW 43rd Street. This runoff from the Panther Creek Wetlands and Panther Creek then enters City storm systems which directly outlet into Springbrook Creek. Improvements to the existing ditch along the westerly side of SR-167 could provide improved water quality benefits and possibly improve the local drainage problems in the vicinity described earlier. The City of Renton requests that the proposed P-9 Channel/Panther Creek Wetlands culvert under crossing of SR-167 be constructed as an important component of the SR- 167 HOV project. This facility has been identified as part of the United States Department of Agriculture Soil Conservation Service and City of Renton East Side Green River Watershed Plan since the early seventies. This would provide a defined Paul Prochaska CTS Engineers, Inc. Page 2 drainage path that would allow hydrologic and wildlife corridor connection of Panther Creek and the Panther Creek Wetlands with'Springbrook Creek which would allow fish passage small mammal immigration from Springbrook Creek to Panther Creek. IBased on the HSPF model, the design flows for the 2, 10, 25, 50, and 100-year flood frequency from the Panther Creek Wetlands through the proposed.P-9 Channel control culvert crossing of SR-167 is estimated to be 161, 227, 264, 294, and 326 cfs respectively by Northwest Hydraulic Consultants with the HSOF model. The P-9 culvert should be designed to meet the King County Surface Water Design Manual (KCSWDM) requirements for capacity and fish passage using those flows and accounting for the effects of a maximum upstream and downstream water surface elevations (for 10 year flows and greater) of 16.0 and 14.5 NGVD respectively. Additional information ' regarding the P-9 Channel/Panther Creek Wetlands project can be reviewed in the projects Draft Interim Preliminary Engineering Report prepared by R. W. Beck and Associates for the City of Renton, which has been previously supplied to Alpha Engineers. The City also requests that the Springbrook Creek culvert crossing of SR-167 at South ' 192nd Street be improved for flood peak conveyance and sediment management, and has plugged several times during recent major storm events., This culvert crossing is a maintenance problem for both WSDOT and City of Renton maintenance crews, and has ' resulted in the stream diverting and flowing to the north along the easterly side of SR- 167 to the next crossing culvert which flows into a ditch on the west side of SR-167 in the City of Kent corporate limits. This ditch then flows to the north and enters a limited capacity storm system in SW 43rd Street that flows westerly to Springbrook Creek. This occurred on April 4, 1991 flooding of SW 43rd Street to depths of two to three feet. This condition jeopardizes public safety and we request that the Springbrook Creek culvert crossing of SR-167 at South 192nd Street be analyzed and a solution developed which eliminates this condition from recurring and keeps the stream in its natural drainage course and could even improve fish passage. Based on the HSPF model, the design flows for the 2, 10, 25, 50, and 100-year flood frequency flows of the Springbrook Creek crossing of SR-167 at South 192nd Street ' are estimated to be 43, 65, 78, 88, and 98 cfs respectively. The culvert crossing should be sized to accommodate these flows with the appropriate factor of safety and consideration given to sediment deposition into the system, fish passage, and entrance geometry as prescribed by the KCSWDM. This crossing culvert should be reviewed for placement on a more frequent maintenance schedule. We recommend that the existing and proposed storm and surface water systems analyzed and designed as part of the SR-167 HOV project be performed to meet the requirement contained with the KCSWDM. The project's hydrologic and hydraulic analysis report should address all of the KCSWDM Core Requirements and applicable Special Requirements. This includes providing water quality controls by biofiltration and/or wet ponds along with providing storm water runoff detention when required as specified in the KCSWDM. According to the KCSWDM on-site peak rate runoff control (detention/retention) will not be required for a proposed project provided that the Paul Prochaska CTS Engineers, Inc. Page 3 conditions for "Exemption From On-Site Peak Rate Runoff Control" are satisfied. We expect this will be the case for some portion of the proposed improvements The computational method to be used for sizing of runoff control (detention) facility sizing for basin of less than 25 acres should use the Santa Barbara Urban Hydrograph Method (SBUH) with the Level Pool Routing Method. The conveyance systems for basins of less than 25 acres can be analyzed and sized with the use of the Rational Method. Conveyance and detention facilities for basins of 25 acres and larger must be analyzed with the computational methods as specified on page 3.2-1 of the KCSWDM.

The City is more concerned with water quality than retention/detention, but problem areas are S. 192nd Street and S . W. 43rd. G It was agreed that all calculations should be in accordance with King County Surface Water Design Manual. If the subbasins are less than 25 acres, use the rational method for determining I runoff calculations . It was noted that if runoff was increased by less than 0 . 5 cfs for a 100-year Design Storm it is considered that the improvements have no effect upon the subbasin. ' It was agreed that the runoff parameters consider the existing freeway as it exists today, and the improvements are the addition of the HOV lanes. The City would like to see the state construct the P9 culvert under the freeway SR 167 within DOT right-of-way. The culvert E should be designed in accordance with Chapter 4 of the King County Manual in regard to fish passages, e.g. , a minimum flow of 6" depth during low flow and 800 of culvert area during 100 year Design Storm, without overtopping the roadway section. Design should include the closure of the numerous smaller culverts through the freeway from the wetland area. j It should be noted that if the state would construct the P9 f culvert and make improvements within their R.O.W. , the City of Renton will take care of the completion of the offsite ( improvements required in the Comprehensive Storm Drainage Plan, 1 within the Renton city limits The City would seal/plug the 1 2115-112[h Ave a N.E.

Candid discussion noted that the HOV improvements would have little or no effect on the existing Storm Drainage Facilities. Some of the local problems would be resolved if the existing drainage ditch, along the westerly side of the freeway, would be cleaned, regraded, revegetated and the installation of a new fence. The City of Renton will provide CTS with flow data for the P9 channel and also for Springbrook Creek. Crossing of Springbrook Creek will definitely need improvement (See WDOT intra-department communication from Jim Olsen to Tom Lentz MS779) .

Your comments were received a couple of weeks after the comment period deadline. Therefore, we are replying directly to you instead of including our response within the final EIS. Our responses to your comments are numbered as referenced on the attached copy of your comment memo. A copy of the Final Plan and EIS and EIS Mitigation Mitigation Document are also enclosed for your review. 1) Downstream migration of fish in Panther Creek is identified in the draft plan and EIS because the Washington Department of Fish and Wildlife currently plants coho salmon in the upper reaches of Panther Creek. Panther Creek; after it crosses SR-167, must pass through about 3,OOO feet of storm drainage pipe to outfall into the open channel of Springbrook Creek. The pipe system varies in size from 24" at the upper end to 60" diameter pipe at the outfall to Springbrook Creek. The existing development along the streets through which>the pipe passes would preclude the ability to construct an open channel to replace the pipe system and improve upstream fish passage. Panther Creek Alternative #3 considered replacing the existing storm drain system that Panther Creek flows through with larger diameter pipe for its entire length. However, this alternative was not selected by the City Council for inclusion in the preferred alternative. This is primarily because Panther Creek could change its course in the aluvial fan area upstream of SR-167 so that it no longer flowed through the pipe system, but instead directly flow into Panther Creek wetland. 2) Modeling results show that surface water levels in the Panther Creek Wetland for 2-year events and greater are slightly less than modeled for existing conditions because of the proposed new culvert outlet. Because the modeling predicts that the more severe events do not flood the wetland to as high a level as occurs under existing conditions, then the potential for surface water levels on the east side of SR-167 to impact the roadway embankment should be reduced. Also, it is believed that the locally elevated ground water levels referred to in Panther Creek Alternative#2 have been occurring under existing inlet/outlet conditions for many years due to high surface water levels in the Panther Creek Wetland. Implementation of Panther Creek Alternative #2 with the proposed culvert crossing of SR-167 at SW 23rd Street is not anticipated to elevate the ground water to higher levels than already occur 200 Mill Avenue South - Renton, Washington 98055 Vicki Erickson,WSDOT Response to Comments on the ESGRWP Page 2 under existing conditions. Instead it is the frequency and duration of the locally elevated groundwater levels that are expected to increase because of the increased frequency and duration of inflows. However, there should not be any impact to SR-167 embankment stability since the elevated groundwater levels have already been occurring for many years. Finally, Hong Consulting Engineers concluded in a 1989 geotechnical report that seepage through the SR-167 embankment would be small even if water levels were raised on the east side of SR-167 by approximately 3 feet to elevation 13 feet (NGVD datum). 3) Sections 6.4.1 and 6.4.2 of the plan have been revised to include a brief account of the changes to drainage systems tributary to Springbrook Creek. 4) The requested text change has been made. 5) The ESGRWP as proposed does not include management of wetland vegetation via water level changes. Approval for such an action would have to be obtained through a future separate proposal. The configuration of the control structure is the subject of on- going coordination between WSDOT design staff and the City. If you have any questions in regard to the above,please contact me at(425)277-5547.

Winter PHONa: 440-4642/4540 SLTB=: SR 405 MP 1-2 City of Renton East Side Green River Watershed Project EIS To: Vicki Erickson MS 122 The following comments are offered for your consideration: Page Comment 1-6 JSA Why is downstream migration of fish specified? Why not PC2 - Element 1 migration of fish, allowing passage both ways? 4-3 JSA The added water level proposed against the SR167 embankment 4.3.2.2 under this alternative requires geotechnical evaluation. The SR167 embankment was preloaded over a layer of sand. 2 Excessive velocity through that sand layer may compromise embankment stability. 6.7.1 The historical description should include a description of the truck farming period of land use in the valley, the resulting drainage systems related to that farming, the coordination of SR 3 167 culverts with the established drainage system and the subsequent abandonment of the system in favor of urban development. 8-16 The rational for use of the westerly SR 167 ditch for fish passage 5 should include an observation of the impossibility of maintaining an open waterway with available access. 8-16 A discussion is needed describing the management of wetland vegetation via water levels. The prescriptions will probably change with the accumulation of empirical information, but S WSDOT still needs immediate direction on the range of water levels that may be required for future management systems.

Sub Terra Inc. 8003 118th Avenue NE Kirkland, Washington 98033 Dear Chris Breeds: This is a follow up to our phone conversation of Monday June 23, 1997. Our office is designing a project for the City of Renton on SR 167. This project proposes to install an 84 inch diameter culvert crossing SR 167 at SW 23rd Street. Due to the large volume of traffic in this section of highway we are looking for better methods of installation that are less disruptive to surface traffic.We would like to see what advantages Microtunneling has to offer and whether it is cost effective or not.This project poses many challenges due to the environmental sensitivity of this location and to the proximity of underground utilities. We understand that your company has done a similar project for WSDOT and I would like any comments or suggestions you may have to offer. Attached are a set of preliminary drawings and copies of two Geotechnical Reports. Please feel free to call if you need any additional information. I can be reach at 440-4558 fax 440-4805.

All disturbed soil samples were visually examined and then grouped together based on particle size distribution, consistency, and color. Once groups of samples were established that had similar characteristics, a minimum of one sample per group was tested. The testing consisted of performing particle size analyses, determining the liquid limit if applicable, and determining the plastic limit and plasticity index if applicable. The tests were done in accordance with AASHTO T-88, T-89, and T-90 guide specifications respectively. After the testing was complete, the samples were classified using the Unified Soil Classification System (USCS). The results of all laboratory testing are attached in Appendix B. PROJECT SOIL CONDITIONS The soil materials encountered during the field investigation have been grouped into four general soil units based on engineering properties and material classifications. The units are briefly described below: Unit 1 Fill - loose to medium dense, well graded sand to silty sand with gravel. Unit 2 Soft peat and organic silt with wood fragments. Unit 3 Soft sandy silt to elastic silt with an intermediate medium dense, silty sand layer. The intermediate layer consist of volanic debris which vanes in thickness between 4 ft and 7 ft under the culvert. Unit 4 Medium dense to dense, interbedded layers of well graded sand and gravel to silty sand. In general, Unit 1 is underlain by Unit 2, which is underlain by Unit 3. Unit 3 is underlain by Unit 4. The flow line (bottom) of the culvert vanes between elevation 9.0 ft and elevation To 23N . 9 R . 5Ee9 W . M . � 1 AREA IMPACTED 5600 S0.

The design work was initiated in Decembepk1996. Geotechnical exploration was done and A-,,[e report completed. The geotechnical report for the proposed crossing at SW 23rd Street recommended against jacking and the boring as a construction method. Instead,*k open cut trenching was recommended aWSDOT and the City are extremely concerned about the traffic impacts of open cutting. Open cutting also is more expensive t�h�iR the current WSDOT budget for the project. The current budget for construction �, $401,000. Current construction estimates withiM64o4Uf open cutting kar-round ound $660,000,,with about $200,000 just for traffic contr Th¢cost of the traffic control is also considered potentially low. The 1997 ja 1998 bien fiu i/budget/ s fro my 1 to lone 30th, currently has no money to cover the cost overrun. WSDOT program staff `12� 9� finds�a it RK difficult to justify the transportation benefits of the proposed SR 167 culvertAi potential cost saving / me T% construction nmthod of micro-tunneling was discussed for _X.Q� its EMI a .peteRtm- Copfion. The City feels that WSDOT has a legal obligation to come through with installation of a culvert even if it means appropriating additional funding. The City believes that the State should honor its agreement with the City that was signed in 199)committing WSDOT to rt. :n or i n ign a er t L..lat- eG Sf'fB'f • The planned Upper Springbrook�rossinFptt092nds is now a part of the'OW� ase IA t1V-e,4- �, but WSDOT is thinking about aking it out and combining it with the SW 23rd Street culvert.

The City is responsible under the 1995 agreement four ta'ning all of the necessary permits including Corps of Engineers,Department of Fish and Wildlife,tem orary water odification and others. Action items: / o The City will provide WSDOT with more information on the background of the State and City coordination regarding the proposed culvert on SW 23rd Street�as well as the plugging of the other poorly function culverts.'The City will also coordinate with C lu cio an other contractors regarding the feasibilityAotc o-tunneling tFu tierrrxod��a a�t} st.

Box 330310 Seattle, WA 98133-9710 SUBJECT: SR-167 CULVERT IMPROVEMENTS COMMENTS TO INFORMATION RECEIVED 5/9/97 AND 5/14/97 Dear Ms. Suafoa: I recently received the following information for the planned SR-167 culvert improvements: Information received May 9 • Culvert Profile drawing • Drainage Details drawing • Drawing showing plan and section of channel work downstream of SR-167 Information received May 14 • Wetland/biology report I have reviewed the information and am returning comments for your consideration. I have made the comments directly on the enclosed copies of the drawing and wetland report documents and have also attached a separate comment sheet to the wetland report. Your assistance in addressing the comments as soon as possible is very important and greatly appreciated. The project Corps of Engineers permit application cannot be submitted until I have received the revised drawings and report. When you return the revised report and half-size drawings, please also include the following drawings plotted on 8-1/2"xlI" paper using the Corps of Engineer permit drawing format your agency typically uses: • Vicinity map (Please see the edits on the vicinity map in the draft wetland report. Please indicate on the form that the datum is NGVD 1929. In the space normally used for listing adjoining property owners, please include note "see table". I will provide a list of adjoining property owner as a table to attach to the JARPA application.) • Plan views as needed showing the location of the proposed actions. Please include the overflow"channel'at the Panther Creek diversion in the plans, being careful to note that the overflow channel is a proposed mitigation measure. • Profile of proposed SW 23rd Street culvert and outlet channel. 200 Mill Avenue South - Renton, Washington 98055 AA---------------.. .-.... ------, ----- Biology/Wetland Report , Supplemental Comments Page 2 • Detail(s)of Panther Creek diversion structure (pipe replacement). This may not be needed if all of the necessary information can be included on the plan view. • Details of the control structure on the SW 23rd Street culvert and cross section of channel grading downstream of the new SR-167 culvert. Your assistance in providing the drawings in the Corps permit application format is appreciated as much time would be lost converting the files from Intergraph to AutoCad release 12 files and then trying to plot the AutoCad drawings with the appropriate line weights. Thank you for your help. If you have any questions, please contact me at(206)277-5547. Sincerely, Scott Woodbury, P.E., Project Manager Surface Water Utility U:65230:SRI 67:97-005:SW CC: Ron Straka 2 Biology/Wetland Report Supplemental Comments 1. I had thought that this would be a supplemental report to the original report done for the HOV lane widening project. Because of the history and relationship of the proposed culvert improvements to the HOV project, I feel that the wetland designations should be consistent with the original report and should also be correlated with the designations in the City of Renton's wetlands inventory, a copy of which is included in Volume 2, Appendix A-2 of the East Side Green River Watershed Project EIS. What this report calls "Wetland B" is really Wetland P4 in the original WSDOT report. 2. The primary purpose of the report should be to confirm that the original delineations completed under the previous (1994) wetlands report are still valid. The report lists that the wetland impact areas at SW 23rd Street were reflagged. I don't feel it is necessary to reflag the wetland boundaries at the other impact locations because the steep SR-167 fill slopes define the edge of the wetland. Again, the report does need to state that the original delineations are still valid and why some were not reflagged. 3. Based on our crest stage gage data (see appendix A-2 of the City's EIS), I would estimate that the wetland boundary should extend no higher than elevation 13 along the floodplain portion of the Panther Creek Wetland (north of Sta 1080+00). Above that elevation the hydrology is very limited. Based on this observation, it appears that the wetland boundary on the east side is shown to extend too far up the SR-167 fill slope, maybe as high as elevation 20 near the top of the slope. I suggest that the report describe the limits of the wetland along the fill slope in terms of elevation to clarify that it does not extend too far up the fill slope. 4. The wetland report should discuss wetland impact, not mitigation. Detailed descriptions and mitigations for the proposed project actions are disclosed in the City's EIS and will be included the JARPA. There will be no permanent loss in wetland area or any significant negative change in character of the affected wetlands. Any temporary impacts will be restored. 5. The wetland report maps should include the locations of the wetland impacts related to plugging of the existing culverts and the diversion structure at Panther Creek. The report must describe the impacts from these actions in addition to the proposed culvert and channel at SW 23rd Street. 6. The report lists in several locations that the wetland area directly impacted is 4600 square feet. This number will change after the culvert plugging and diversion structure actions are included in the report. We need to make sure that the several separate impact areas listed on the plans add up to the total area impacted as listed in the report. Please include in the report a table showing for each impact location the wetland area impacted and the type of vegetation impacted. Biology/Wetland Report Supplemental Comments Page 2 7. In addition to the direct impacts due to the proposed actions, there are also indirect hydrology impacts. Some seasonal hydrology input from the Panther Creek Wetland into Wetland P4 will be eliminated and the flow of Panther Creek through Wetland P5 will be completely eliminated by the proposed work. These impacts are thoroughly discussed in the City's EIS and will be addressed in the JARPA and thus do not need to be addressed in the report. The report should focus on the direct impacts and simply reference the JARPA for information on the indirect effect of the hydrology changes. Because of the indirect effect on Wetland P5, the report needs to reconfirm the delineations for Wetlands P5 in addition to P4 and Panther Creek Wetland. 8. I did not find any reference to Appendix E in the report. Do we really need Appendix E? If we do, I would like to go through each function with your wetland biologist to reach agreement on the rating number that would be assigned. z '+133HS As NOISIA3H 31YO 3LVa 31I .�0ad lii3A"Ill) •94NWNW olonrAo •r •nar lrNo1938 0 NosNHor 'r •89N3 •road 133x f 5 .$ � uoi;oyodsuo"l�o ;uaw;.lodap /�� a;o;5 uo;6uiyso/y; �/� � 9m tlI31NInO'w AB 03tl31N3 '7 la3Alf1�- HStlN 01 8131Nino•W AS 03NOIS30 SAY•as M31N3J 371AM35 'EINIM39NIDN3 ONV 1V1N3WNOMIAN3 •ON•rOad Olb•O3j lrl d yy 0191 J 2/� p/ / a��S --- - ------- ------ - - -- ----- .. .. ... .. ----- - .. .... . .. ... ... . . ..... .. ._ . ..... _ - - ------ Q o .... - - - -- -- - ,aG/. - .. .. - ' 0 ... . ..... .. ... .... .... .... .... ..... .. / I .... .. ... _. _. . . ...I...... ... _........ .. . 3M_.. ......... _._. . . .. . ..... ...... .._.... ... ........ ................................................................................................ . .......... .. .... % . .. ..... .... ............................................... la3A1no ..... .............. .. .... .... .. ... _ .................. ..... . .......... ......... .......... ............183A.7..M.A09.....,.9...X .L...... . . ......... ......_ .... ......... .......... .......... __ ....... ..... ..... ... . .... �..r ---- --- -- — a — — ----- b -- t.fdeV .ro.�d #.. ----- L— — — — — — — — — — -- — -- --39tlN`.1 —HSINia � .. .. . ... .. .. ... .. .. .. .. .. .. .. .. .. .. .. ... ..... .. .. .. .. .. ... .. .. .. . . . . . . . .. ... .. .. . . . .. ... .. ................. ... .. ................... ............................. .. ... ............. . ..
