March 12, 1998 Transportation Systems PlanningBuilding/Public Works 200 Mill Avenue South Renton,Washington 98055 RE: Request for Proposal- Oaksdale Avenue Extension-Phase 2 Wetland Permitting and Mitigation Dear Lin: It was nice speaking with you last week. I appreciate your request for a proposal from Parametrix to assist with the evaluation and selection of a preferred wetland mitigation option for the Phase 2 Oaksdale Avenue SW Extension Project. Based on our meeting, I understand the critical need to develop a mitigation plan that will successfully be permitted by the Corps of Engineers. Parametrix is well-qualified to perform this work as we have coordinated numerous wetland mitigation and permitting projects for street and other public works projects. Our recent or ongoing projects involving wetland mitigation,permitting,and agency coordination include the following: • Natural Resource Permitting and Mitigation Design for Seattle-Tacoma International Airport Master Plan Update,Port of Seattle(Barbara Hinkle,206-439-6606) • South 2000' Street/196`t' Street Improvements, City of Kent Engineering Department (Tim LaPorte,253-859-3593) • Everett-Seattle Commuter Rail Project, Regional Transit Authority (David Beal, 206- 689-3524) • 132nd Street SE Extension, Snohomish County Department of Public Works (Lorna Smith,360-388-6406) • -Sammamish River Habitat Improvements, City of Redmond (Cathy Beam, 206-556- 2429) • Third party review of wetland mitigation plans, City of Renton(Peter Rosen, 425-235- 2719) These projects are successful because of the depth of technical expertise and regulatory experience Parametrix Staff bring to them. I manage four wetland biologists, with Bachelors and Masters degrees in Botany, Aquatic Ecology, and Plant Biology. In addition, our wetlands team is supported by in-house fisheries biologists, hydrologists, geologists, survey teams, or design engineers who can assist in evaluating wetland mitigation feasibility and design. Parametrix' ability to efficiently perform interdisciplinary review of engineering and ecological issues assures our mitigation strategies are complete and meet agency requirements to provide multiple wetland functions. ® Pnnte�!�)n 2ecvcleO p-iner A Key staff available to consult with the City of Renton on these issues include: • Clay Andean (Botanist)-consults on issues related to native plant species selection, and control of invasive plants in mitigation sites. • William Kleindl(Aquatic Ecologist)-is expert in ecological analysis of wetlands and design of mitigation wetlands to mimic natural systems. • Bob Sullivan (Fisheries Biologist)-assists with incorporating fisheries habitat into wetland mitigation designs. He will be consulted on the design of Banking Site 2 to provide fisheries habitat. • Paul Fendt(P.E.)-assists biologists with engineering cost estimates and design for wetland and fisheries mitigation projects. • Ground and surface water hydrologists-assist with monitoring well installation, data collection, and hydrologic analyses. • Parametrix Survey Team-provides elevation and mapping of mitigation sites to create base maps needed to support mitigation designs. • Landscape architects-assist wetland biologists in designing wetland mitigation planting plans and bid specifications. In addition to having expert staff. Parametrix currently has several ongoing wetland mitigation and permitting projects that involve one or more of the same agency staff who will review and approve the wetland mitigation plan for Phase 2. During recent presentations to these individuals, we have established a strong rapport by outlining logical and ecologically valid project impact analyses, mitigation strategies, and mitigation design options. Our general approach to agency coordination (Task 2)will follow this model and take advantage of this favorable rapport. Since our discussion, I have visited the mitigation sites discussed. I also reviewed the JARPA application for the project, aerial photographs, topographic mapping, recent hydrologic data for the project area, and conceptual designs developed as part of the mitigation bank project. In conjunction with our work on the wetland mitigation bank project, we have measured the bankfull water level and recent flood elevations on Springbrook Creek adjacent to Mitigation Site 2. Based on this review, as further explained in our proposal, we believe all options present viable mitigation opportunities to compensate for filling 1 acre of wetland on the Phase 2 project. Because of this preliminary conclusion,our proposed work for Task 1(Evaluation of Mitigation Options)focuses on re-evaluating existinp' data rela�tre to the mitigation needs of this project. Limited additional data may be needed �estimate potential al construction costs and to further demonstrate the feasibility of certain wetland mitigation options to the review agencies. 440 "`'� ',I-- �' � ��'f�� 4-` We WAn/, fb lI/ K><l dqi'� /gVef ^o t tNoNICt kUuW a rl7 ,7s4y In summary, Parametrix offers qualified staff with divers consulting experience to address the variety of regulatory, ecological, and engineering issues that are required to successfully complete the mitigation permitting and planning for the Oaksdale Avenue project. Our approach has proven cAd G O v rl, successful on a number of similar projects. With 12 years experience in wetland consulting in d ear h t� Washington, I bring the City the senior level consulting expertise necessary to assure your project I goals and schedules are met. /1110c !'

Kelley, Ph.D. Wetland Ecologist/Project Manager' J City of Renton-Transportation Systems Oaksdale Avenue Siv Extension Project Submitted by Parametrix, Inc. Phase 2 Wetland Mitigation 2 :March 13, 1998 PROPOSAL CITY OF RENTON OAKSDALE AVENUE SW EXTENSION—PHASE 2 EVALUATE WETLAND NIITIGATION OPTIONS AND NEGOTIATE WITH AGENCIES Parametrix,Inc. Kirkland,Washington 98033 UNDERSTANDING The City of Renton received a Clean Water Act Section 404 Permit to fill wetlands associated with the Oaksdale Avenue SW Extension Phase 1 project. A Permit for Phase 2 of the project was specifically denied, pending development of a suitable wetland mitigation plan. Approval of Phase 2 under Section 404 will require a permit application, public notice, and supporting documents, including wetland mitigation(2 acres). Potential mitigation options for Phase 2 wetland impacts are as follows: • Removal of fill from City of Renton property located south of SW 27`h Street and east of Oaksdale Avenue. This option would allow restoration of about 2 acres of wetland. Establishment of wetlands with in this area would mitigate for impacts in proximity to the project. This restoration project could be designed to avoid removing most trees rooted near the edge of the fill,which would enhance the net habitat benefits of the project. Since there appears to be about a 1 foot drop in surface water elevation across the existing fill, it may be desirable to replace the existing culvert with a weir type structure to avoid hydrologic impacts to wetlands located west of the fill. A weir control structure would reduce the likelihood that clogging of the culvert would affect wetlands or adjacent property. • Use of the wetland mitigation bank Site 2, adjacent to Springbrook Creek offers significant mitigation potential for impacts associated with the Oaksdale Avenue project. It would allow in-kind replacement of shrub, ent, and forested wetland habitat, as well as allow out-of- kind mitigation such as fis f itat enhancement. However, since fisheries enhancement opportunities in Renton may be limited,the use of the mitigation bank for projects not requiring fisheries mitigation may be undesirable. This issue will be considered in evaluating this mitigation option. • Use of wetland mitigation bank Site 1 as a mitigation option appears feasible. This site was originally rejected by the regulatory agencies because initial studies suggested a liner would be needed to establish adequate hydrology. However, hydrologic data, geotechnical analyses, and observations of adjacent wetlands suggest the "fatal flaw" of a lined wetland is unfounded. If this option is pursued, a strategy to present persuasive data showing that a liner is not required aar is ^ will be needed. A 4 v Raw City of Renton—Transportation Systems Oaksdale Avenue SW Extension Project Submitted by Parametrix,Inc. Phase 2 Wetland Mitigation 3 March 13, 1998 } • A final mitigation option, not discussed with the City could include a combination of the above mitigation options coupled with wetland enhancement on City owned wetlands. Enhancement opportunities include conversion of lower quality reed canarygrass wetland habitat to shrub or forest wetland habitat, or enhancing forested wetland habitat with evergreen tree species such as red cedar and/or Sitka spruce. Additional enhancements to be incorporated into mitigation planning include wetland buffer enhancements. Buffer enhancements include planting buffer areas with evergreen trees and food producing shrubs to provide screening, cover, and forage for wildlife. If this option is viewed favorably by resource agencies rents, it may provide a relatively low cost mitigation option because earthwork costs would be minimized.

Task 2-Agency Coordination Purpose: The purpose of this task is to coordinate with City departments and resource agencies to explain mitigation options and design approaches, solicit feedback, and ultimately select a preferred mitigation option. Activities: Conceptual mitigation plans and feasibility analyses of mitigation options will be presented to resource agencies with review authority over the Corps of Engineers permit. Based on agewy review and comments and City of Renton review,a preferred mitigation option will be select Vd, e intent of this coordination is to demonstrate responsiveness to the concerns and recommendatf reviewing agencies,and(if necessary),convince them that alternative approaches are valid. Coordination with agencies is expected to include initial telephone consultation to discuss the project and mitigation approach. An information packet would be prepared and circulated to agencies prior to an office and field presentation. Following the field meeting, additional meetings or telephone coordination would be conducted to inform agencies of new information or relevant decisions. It is especially important to meet with agencies prior to issuance of ublic notice and early during the official comment period so that all agency questions arising Qfo their review are proactively answered. Products: Products of this task include records of telephone communications, minutes from agency meetings, preparation of meeting materials,and attendance at these meetings. ff / a)�uj d J ,4 Sn.• t * Covet l iu tY� `Z hd�d 44 i�/C- �-Ae / �� hh1 SZ►- H:\USERS\KELLEY\RENTON\Renton.scp.doc a�f-� f 64n1ii 4Pk:. , 1 47 5 WL rC CAt7v2 Can 4rl ch 41L— f 4 �6"fS 6�U C e 1&,ViC 'C�C�GGt ki A eel � 1�4 0A rt e-Wr, Ste„,e 0„2 c,�a, r l.�i ✓4 T a l� ,� City of Renton-Transportation Systems �/1�1 r / -- Oaksdale Avenue SW Extension Project Submitted by Parametrix,Inc. „a'✓� Phase 2 Wetland Mitigation 5-0 �lf�d q �5 �C / C� r1�' arch 13, 1998 Cl,-E, t, � � /�h 1i r'1 e 4errn Parametrix, Inc.

Our concerns and comments are outlined below: The Compensatory mitigation plan should include clearly outlined goals and objectives, performance standards (including % cover at years 2, 3, 5, 7, and 10) , monitoring, maintenance, and contingencies. Contingencies need to be developed up front, not "if- a Problem occurs down the line. Presented for our review on the mitigation component of this project is two pages of narrative, one page of a plant list, and two drawings. We strongly reccmutend that you prepare a bound compensatory mitigation plan which includes the function and value asseasment of the wetlands being impacted, which functions you are trying to replace and how that will be achieved at the mitigation site. The plan should also include information about existing site conditions (see below) . It is extremely difficult to relate impacts to compensatory mitigation and the ecological validity of the mitigation plan when the information for assessing these components for our permit decision are either not available or scattered in the DEIS, the EIS, letters, Public Notice, etc . Given the sensitive nature of this FEB-03-19M M 35 FROM US COE-REGLILATORY PRANCM TO 972M P.03 project, compilation of all the pertinent information in one volume (the Final Mitigration Plan) for our review and future wise is imperative. • The following information about existing conditions at the proposed mitigation site is required. How big is the entire parcel? Is the entire parcel owned by the city of Renton? What is the acreage, location, and types of jurisdictional wetlands which exist there now? We observed jurisdictional wetlands on the mitigation site, dominated by reed canarygrass (RCG) during our site visit of June 12, 1997 ; however, we need data pertaining to the existing hydrology, vegetation, and soils, both in the upland and in the wetland areas of the proposed mitigation site. The information provided is not enough to ascertain the probability of sucoeaa for the proposed compensatory mitigation plan. Your estimates for cubic yards (cy) to be excavated for the mitigation site appear too low. For the northern area our estimates of excavation needed would be about 10, 000 cy of material (averaging 4 feet of material to be excavated trom an area approximately 65, 000 square feet) , while you indicate that it as approximately 5,500 cy of excavation. Our estimate (based on the graphics presented) for the Southern area was also about double your estimate for excavation volume. Please clarify. Section C-C ha$ the existing and proposed grades labeled incorrectly. Where will the excavated material be disposed of? What are the hydrological parameters at elevations 10 .5 through 15 feet. What is the existing hydrology at elevation 14 feet for the existing wetland? . The drawings are riot clear how the stormwater is retained and separated from the Wetland at the mitgation site during times of heavy rainfall and/or flood conditions. The cross-sections indicate very little separation between the stornwater facilities and the mitigation wetlands_ what year flood events are the stormwater detention basins designed for? is road runoff being considered as a source of hydrology for the mitigation site? The Corps typically requires a 10-year monitoring plan for corVansatory mitigation projects which have forested wetlands as part of their component. Since that appears to be a goal of the mitigation, we will require monitoring and subsequent xeports in years 1, 2, 3, 5, 7, and 10 . If after year 5 additional monitoring is not warranted then we will not require it . To clarify this we will include a special condition in the Corps permit which will allow monitoring to be terminated. if appropriate, after year five. 2 r- V J FEB-e3-1999 10:36 FROM US COE-REGULATOW BRANCH TO 9720560e F 04 • The mitigation information does not clearly state anywhere that mitigation monitoring reports will be submitted to the Seattle District Corps. It only states that the monitoring reports will be submitted to the city of Renton. • A two-year maintenance program is not enough, especially given the amount of RCG at the mitigation site and the requirement to keep invasive species to no more than 10% aerial cover for the site, What strategies do you plan. on euployi.ng to control RCG at the site? • As you are aware, the wstland mitigation site must be recorded with the Registrar of Deeds or other appropriate official Charged with the responsibility for maintaining records to or interest in real property. Proof of this documentation must be provided to the Seattle District Corps prior to permit issuance. This requirement is to ensure that the wetlands created, restored, or enhanced as compensatory mitigation will not be the subject of future ir_dividual or general Corps permit application for fill or other development . This iz of utmost importance for this particular permit action_ • The mitigation information states that tho -litigation ratio of 2:1 will designate 0-62 acres of the total 2.05 acres of created wetlands as mitigation for Phase 1, and that the remainder of the 2.05 acres would be applied to other projects within the city of Rentow s juriediction. please be aware that if the city of Renton wishes to utilize the "excess" mitigation for a project which. requires a Corps permit there are no guarantees that we could apply the excess mitigation acreage to a particular project. xowever, many projects require local mitigation when the corps does not require any and the use of the site In that vein may serve the City well . We would be required to review the applicability of the extra mitigation for a project in the same watershed on a Case- by-case basis. In addition, we have not determined that 2 :1 mitigation is appropriate in this case (i .e. we usually require a 3:1 ratio for enhancement, not 2:1) . • Please .include a breakdown of th• mitigation acreage components. For example how much wetland (in square footage or acreage) will be enhanced, created, and restored at the proposed mitigation site? • It appears that parts of the mitigation include steep sides contributing to a `bathtub" affect, which is highly discouraged in restoration and creation of wetlands_ This "bathtub' affect is not considered an appropriate mitigation design- Scalloping the edges more (especially in the southern area) and lessening the slopes to create more edge is required- 3 FEH-0?-1998 10:36 FROM US COE-REGULP1UMY btd-"-ti iu • You should also consider phase planting of sun sensitive tree species such as red cedar and red osier dogwood, as they have experienced heavy mprtaliky if planted before some shading is established in other projects . it is our understanding that you are currently working with the Washington State Department of Ecology to resolve their concerns about the CwVensato]ry mitigation plan. Z apologize for not providing these comments sooner, but we are short staffed with an extremely heavy workload right now. if you have any Questions concerning this letter, please call the undersigned at (206) 764-6903 .

BOEING/CITY TOPICS: B.2 RIGHT-OF-WAY: 2/19/98: 3/12/98: Maintenance easements for the. traffic signal detection loops may be required by the City at the entrances to the BCAG HQ and Family Care Center. Discussion was held concerning the Boeing/PSE power line easement agreement. The City will support Boeing and PSE as they resolve the execution of this easement. 3/19/98: The City is researching their records for any special easement/recording issues pertaining to the traffic signal loop installation in the driveway (see also Item D.9). 4/2/98: The Boeing/PSE easement issue needs to be finalized before Tom Boyns(City) can finalize his end of the paperwork. Jon Larscheid will provide an original of the easement to Tom Boyns, with a copy of the transmittal to Lin Wilson. 4/16/98: Joe will nudge Tom Boyns for an answer regarding easements for signal loops. 5/7/98: We are awaiting clarification from Tom Boyns on the requirements for easements for the signal loops. 5/14/98: The City completed the research and submitted a modified easement to Boeing for acceptance and execution. 5/21/98: Jon indicated that Boeing's attorneys did not favor the form of document prepared by the City and would prefer the lengthy form previously submitted. Lin asked if Boeing would research the form of agreement used at existing locations, such as Park/N. loth Street, to serve as a model. Alternatively, he suggested, Boeing could offer to maintain the loops on their property, rather than relying upon City personnel. Tom Boyns will have further discussions with Boeing personnel towards adopting an appropriate Citywide approach. 7/9/98: Tom Boyns has received the draft paperwork from Boeing. (Pending) Done B.2g Discuss Citywide procedure with Boeing ACTION ITEM City Oakesdale Avenue S.W. Page 2 1 Construction Coordination Minutes July 9, 1998 B.4 LANDSCAPING: 2/19/98: Issues relating to modifications of the existing irrigation system are listed under "POSSIBLE CONSTRUCTION CONFLICTS" in Jon Larscheid's memo dated February 17, 1998 and will be addressed through the mechanism in the construction contract for the subcontractor to submit plans for approval. These plans must reflect the need to preserve irrigation capability during the construction period. The City's contractor should establish these needs in consultation with Teufel, Boeing's landscape maintenance contractor(contact Larry Harger, telephone number available from Jon Larscheid). However, there should be provisions to allow flexibility in meeting new irrigation needs, including new plantings installed in connection with the Oakesdale project. The existing 4" line crossing at Station 44+30 should be retained, and additional sleeves installed as agreed with Boeing. 3/12/98: Jon provided the location for new sleeves. 5/14/98: The City's consultant is currently working with Osborn Pacific Group (OPG) to bring them on board. Controlled Rain is concerned with the layout requirements for the new landscaping. Controlled Rain will be responsible for the current system. The City's right-of-way landscape consultant will take care of the irrigation design for new features. Steve Goetz will be the contact person for coordination regarding existing facilities. 5/21/98: An initial meeting was held on 5/20 between Linda Osborn(OPG), Boeing, Peter Hummel, Steve Goetz, K&W and the City to discuss the scope of OPG's work. (Pending) B. 5 TRAIL LINKAGES: 2/19/98: Jeff believes that restoration of vehicular access to the stormwater outlet vault south of the new bridge is a roadway issue. It was agreed that there would be a special meeting to discuss this and other trail connection issues, to include Scott Woodbury and Leslie Betlach. 5/14/98: Lin asked for the as-built location of the existing trail at the southeast corner of the CSTC wetland. Larry Harger clarified the location. 5/21/98: After the meeting, Joe, Jon and Lin met in the field and walked the route of a path that would stay above elevation 13 and pass between the existing trees with a minimum of disruption. 6/4/98: Lin noted a change order will be forthcoming for a curb cut and crushed rock trail just north of the fence, between the trees. 1 or 2 trees may need to be removed and the trail must remain above elevation 13. 6/11/98: Boeing has requested the trail be paved, using project funds. Lin advised this particular item will be elevated to the Steering Committee. 6/18/98: If the cost of the irrigation relocation performed by Boeing/Teufel(Item D.7) is comparable with the extra cost of paving,the paving will be included in the change order. 6/25/98: Jon stated that, contrary to what is noted under 6/4/98, above, Boeing does not want a curb cut for the trail. 7/9/98: The west end alignment will carry out to Oakesdale, with no curb cut. The change order will include paving. (Pending) B.5 Process Change Order for trail provision ACTION ITEM City B.6 FIRE TRAINING EXERCISE: 7/9/98: Scarsella will coordinate with PSE and TransTech for the required power electrical drop and relocation of construction trailers required for the fire training exercise which takes place on the 22nd through the 25th. There will be a series of 8 burns,with the final(big)burn taking place on the 25th. Boeing will request that fire equipment not block construction access during the exercise.

Page 3 Construction Coordination Minutes July 9, 1998 D. SCARSELLA CONTRACT -- GENERAL DISCUSSION: D. 7 LANDSCAPING: 3/12/98: It was stressed that protection of Teufel's existing landscaping items is considered a priority item. 3/19/98: The City will provide a change order to Scarsella for new sleeve locations. One sleeve is an irrigation sleeve.4/16/98: Irrigation submittals should be ready next week. 5/7/98: Baugh inquired as to the timing for landscaping on the east border. Jon advised it will be pretty close to what's listed on the Master Schedule in the other room. 5/14/98: Teufel (Larry Harger) stressed the necessity of maintaining moisture to planting materials in the hot weather. They need to know the status of the added sleeves. The main line across the right-of-way at Wall H needs to be restored as soon as possible. This should be done by the end of next week. Boeing requested Teufel take responsibility for any repairs, and offered to accept the charges for same. This was approved by all concerned. Controlled Rain will repair the lateral lines (mostly on the east side) by individual zones. The 2" power and communication conduits for the monitoring station have been repaired. The 6"sleeves at Station 47+65 (plan sheet 98)will be installed as soon as Wall C is completed. Scarsella was reminded that Change Order #8 needs to be executed in order to procure the sleeves in a timely manner. Jon clarified the lake vault,the control station and the monitoring station are the only items which require conduits. 5/21/98: Jon and Steve requested the provision of an additional 6-inch sleeve parallel with the 2-inch sleeves previously requested. This will be added to the C.O.currently in preparation. 6/11/98: A coordination meeting was set for 7:30 a.m. next Tuesday, 6/16 at the Boeing offices, to discuss the scope of Controlled Rain's and Teufel's responsibilities. On another note, Teufel would like to start work west of Oakesdale on the south side of the parking lot. The area is staked. Karl will coordinate with Teufel. 7/9/98: Frank will schedule a meeting with Controlled Rain for the beginning of next week to go over all outstanding items. (Pending) D.7 Coordinate irrigation needs with Teufel ACTION ITEM Ongoing D. 20 CHANGE ORDERS: Joe reviewed the status of Change Orders issued and in preparation,as follows:(ongoing) No. Description Scope Cost Executed Executed Defined Agreed (Contractor) (City) Provide connecting trail(B.5) Revise irrigation scope to reflect items performed by Boeing/Teufel (D.7) SW 27th electrical changes: add breaker and change wiring size/qty; change pole foundation sizes(D.44) Provide CL fence between trail and Wall G (D.55) D.31 POTENTIAL CLAIM: 4/16/98: Scarsella has not received any formal notification from Malcolm Drilling representing their potential claim for changed conditions. Malcolm has demobilized and is off the project. The City's impression is that Malcolm resumed satisfactory production, without the need for extraordinary equipment or methods,and presumes that the impact of any conditions unforeseen by Malcolm were negligible. If Malcolm believes this is not the case, prompt notification should be made through Scarsella. 4/30/98: Nothing has been received to date. 5/7/98: The City has received paperwork from SBI concerning Malcolm's claim. 5/14/98: The City will be transmitting to Scarsella a letter from Shannon & Wilson commenting on Malcolm's claim of changed conditions. 5/28/98: The City's response has been sent to SBI. 6/11/98: Malcolm would like to meet to discuss their claim. SBI will schedule a meeting for next Wednesday, 6/17. 6/18/98: An initial meeting was held on 6/17 and will be continued next Tuesday,6/23,at 9 a.m. 7/9/98: The next meeting with SBI and MDCI is scheduled for Monday 7/13,at 9 AM. (Pending) D. 33 CONCRETE POUR: 4/30/98: Karl explained that after ARM started their pour it was discovered the approved submittal was not what was wanted on the project,which caused a shutdown. The contractors are tracking their costs associated with this shutdown. Jerrod explained that the submittal referred to the footings. He further i I Oakesdale Avenue S.W. Page 4 q Construction Coordination Minutes July 9, 1998 explained that, per Standard Specs., any concrete above finished ground must have air in that portion of the work, and this requirement never varies. As such, there should never have been a problem with the pour. 5/7/98: Allen (ARM) stands firm in his contention of lost production time and advised a letter will be forthcoming. Arlen (Entranco) noted, for the record, that the concrete was not wasted and it was a very short hour, at best, which may have been lost. 5/14/98: ARM is willing to accept the added cost of the concrete. However,they are requesting payment for the additional hour. 6/4/98: ARM will submit details to substantiate the request for additional compensation by next week's meeting. 6/11/98: ARM has forwarded information to SBI for processing. 6/18/98: The City has received some information from ARM via SBI, but it is not in the format required by the WSDOT Specifications. Lin requested it be re-submitted in the appropriate format, with an explanation of the contract provision establishing that the extra cost is a City responsibility. Upon receipt of the revised request, Entranco will be asked to review it. Scarsella will ask ARM to resubmit their request for additional compensation. 7/2/98: Allen(ARM)objected to being asked to re-submit his paperwork, and asked the City to prepare it for him to sign. Lin Wilson and Ed Berschinski tried to explain that it was necessary to have it in the proper format and that only his firm would be aware of the actual applicable charges and processes which were impacted. The discussion carried over to other issues and this item remains at an impasse: The City can do nothing for ARM unless/until the proper paperwork is received for review. Frank (SBI)will work with Allen on this item. (Pending) D. 33. Resubmit request in appropriate format ACTION ITEM Scarsella/ARM D.37 ALIGNMENT OF MODULAR BLOCK WALLS: 5/7/98: Jerrod advised that it would be wise to establish survey points along Wall C to allow for checking settlement in the future. It was agreed this will be done. 5/21/98: As soon as sections of Wall C are completed to full height, settlement markers will be established and monitored at weekly intervals by Entranco. 5/28/98: Markers have been established. Entranco will monitor and provide weekly updates. 6/4/98: Ed provide a spreadsheet summarizing settlement markers elevations observed during the first ten days after the initial. 6/11/98: The weekly log was submitted by Ed Berschinski. 6/18/98: As of 6/17 there has been no movement. It was agreed the next reading will be taken in about a month(3 to 4 weeks). 7/9/98: New readings are to be taken within the next week whenever the surveyors are in the area. (Ongoing) D. 37. Monitor Wall C settlement markers ACTION ITEM Ongoing D.44 S.W. 27TH STREET INTERSECTION: 6/4/98: The j-box in the intersection is the termination point for the luminaire runs on S.W.27th Street. The j-box was rendered inoperable by City forces and will be relocated by TransTech Electric. Killing power to this box also left one luminaire(Station 10+90 left)without power. This pole might be in conflict with the new radius and may need to be relocated. SBI will have it surveyed. 6/11/98: This luminaire may be a future conflict(during Phase 2), but for this project, it should be okay. TransTech will submit a proposal showing how the layout could be modified. 6/18/98: The City believes it may be best to eliminate this particular luminaire from this contract and salvage the pole for future use. Joe Armstrong will coordinate and ask City forces to remove the pole. 6/25/98: The pole has been removed and salvaged by the City. The Contractor will submit a force account billing for their portion of this work. Two changes to Plan Sheet 73 were discussed: 1)one breaker will be added to the cabinet(Note#2);and, 2)wiring will be changed from two#4's to three#2's(Note#3). A change order will be processed to cover these changes. 7/2/98: The PSE transformer is due on July 22"d. 7/9/98: Proposed changes to pole base dimensions (see Item D.56)will also be covered in the Change Order. (Pending) D.44c Submit force account billing ACTION ITEM Scarsella D.44d Process electrical change order ACTION ITEM City D.48 ILLUMINATION AT BRIDGE STRUCTURE: 6/4/98: The j-box for future trail lighting may be routed from the luminaire base closest to the bridge abutment(Luminaire Note 1). This would remove it from the bridge deck location. 6/11/98: Alan(TransTech)commented that they were unable to coordinate with the installation of the modular block wall. This has resulted in their inability to install these conduits as originally planned. Surface mounting will now be a necessity, which will require a re-design for these conduit runs. Entranco will review Oakesdale Avenue S.W. Page 5 Construction Coordination Minutes July 9, 1998 and advise. 6/18/98: TransTech, earlier in the week, proposed a design to support the luminaire poles at Wall "C"on a spread footing at sidewalk level instead of drilled foundations at the base of the wall. This proposal is not approved; the original design on the plans will apply. Entranco will determine the routing of conduit runs from the bridge deck down to these luminaire poles; the re-design should be completed by Friday, 6/19. 6/25/98: The re-design was presented and needs to be re-worked. Galvanized rigid steel conduit is to be used on all exposed runs. 7/2/98: The re-design by Entranco has been completed and transmitted to all concerned parties. (Pending) D.48a Process change order for bridge conduit revisions ACTION ITEM City D.49 S.W. 20TH SIGNAL LOOP RUN 6/11/98: The j-box needs to be set back behind the silt fence. Scarsella noted this should not pose a problem, as long as TransTech can get in and out before any extended rainy period sets in. Alan(TransTech)thought they might be able to get in and trench using a small ditchwitch type of machine. This would speed up the installation process. The City agreed to expedite the review and approval of RAMS for this signal. 6/18/98: This City has not yet received the RAMS submittals from TransTech. (Pending) D. 52 LANDSCAPING SUBMITTAL: 6/18/98: The City is awaiting the "Irrigation Relocation" lump sum breakdown submittal from Controlled Rain. 7/2/98: The City reminded SBI of the need to obtain this pricing breakdown. Frank will pursue it with Controlled Rain. 7/9/98: A meeting will be set for early next week. (Pending) D.52 Provide lump sum landscaping breakdown ACTION ITEM Scarsella/C.R. D. 54 STOP WORK ORDER: 6/25/98: Frank noted he had been presented with a Stop Work Order by the Seattle Water Dept. last Friday afternoon, 6/19. They experienced approximately 2 hours of lost time on rented equipment,etc.and will submit under Force Account for payment. (Pending) D.55 WALL TOPOGRAPHY: 6/25/98: Two items: A. The irrigation vault lid (Wall C) is at a different height than the sidewalk and is susceptible to falling debris. Scarsella would like to extend the wall approximately 10 feet south, at the same height, or perhaps higher, if the slope is to be decreased from the 3:1 ratio. 7/2/98: The block wall will be extended south and paid at unit pricing. B. Wall G, Plan Sheet 24, Station 14+00, in the vicinity of the pole: The top of slope goes into the trees, extremely close to the parking lot. Also, there's no drop-off protection for peds using the trail. Entranco will do a site inspection after today's meeting and submit suggestions at the next meeting(7/2/98). 7/2/98: The design intent was to achieve a 5%slope,with a 3:1 back slope on cuts and protection of the trees. The back-slope from the trail back to the parking lot can be steepened. If this does not solve the problem, the 5%trail profile could move 40 feet south, and the profile of Wall G be raised. Shrub plantings were intended to be used for pedestrian protection,but a protective railing or fence may be needed. Entranco will have a re-design on this portion of Wall G by the middle of next week. (Pending) D.55 Investigate and provide options ACTION ITEM Entranco D.56 POLE BASES: 7/9/98: Signal pole bases have been revised from a 15 foot depth down to a 12 foot depth. Luminaire pole bases will now be 6 feet deep instead of 7 feet deep. A change order will be processed for this item. (Pending) D.56 Process pole base change order(see D.44d) ACTION ITEM City D. 57 WATER QUALITY VAULT: 7/9/98: The inlet connection to the vault as designed will pass through a joint between precast panels. Scarsella will field adjust to lower the connection. Also, the 8" maintenance drain is shown placed on an angle with the vault wall, which will make it difficult to mount the shear gate. It was agreed a 22-1/2 degree ell will be furnished to allow for a flush/square connection. The vault does not have the access openings flush with the end walls in which ladder rungs are provided. Joe will check with Maintenance whether a portable ladder can be used,or whether a free-standing ladder must be provided.

TransTech will verify the extent of the damage and PSE will reimburse TransTech directly for any required replacement or repairs. (Pending) D. 59 DELAY OF SBI OPERATIONS BY PSE GAS INSTALLATION: 7/9/98: Frank had noted that PSE gas line installation had delayed the start of his planned curb and gutter installation. Lin commented that the contract would allow the granting of additional working days if circumstances beyond the contractor's control caused delay to a critical activity, but that there could be no question of the delay giving rise to a claim for additional compensation. (Pending) D.60 GIRDER DAMAGE: 7/9/98: At 0715 hrs on Friday a boom truck operated by ARM tipped and fell over, with the boom contacting the upper flange of girder M, approximately fifteen feet in from the south end. The apparent damage is to an area 3' long by approximately 14" wide. Concrete Tech,the manufacturer, has been contacted,will visit the site Friday,and will propose the method for repairing the damage. The proposal will be reviewed by Entranco.

A Permit for Phase 2 of the project was specifically denied,pending development of a suitable wetland mitigation plan. Approval of Phase 2 under Section 404 will require a permit application, public notice, and supporting documents, including wetland mitigation(2 acres). Potential mitigation options for Phase 2 wetland impacts are as follows: • Removal of fill from City of Renton property located south of SW 27 h Street and east of Oaksdale Avenue. This option would allow restoration of about 2 acres of wetland. Establishment of wetlands with in this area would mitigate for impacts in proximity to the project. This restoration project could be designed to avoid removing most trees rooted near the edge of the fill,which would enhance the net habitat benefits of the project. Since there appears to be about a 1 foot drop in surface water elevation across the existing fill,it may be desirable to replace the existing culvert with a weir type structure to avoid hydrologic impacts to wetlands located west of the fill. A weir control structure would reduce the likelihood that clogging of the culvert would affect wetlands or adjacent property. • Use of the wetland Mitigation Bank Site 2, adjacent to Springbrook Creek, offers significant mitigation potential for impacts associated with the Oaksdale Avenue project. It would allow in-kind replacement of shrub, emergent, and forested wetland habitat, as well as allow out-of- kind mitigation such as fisheries habitat enhancement. However, since fisheries enhancement opportunities in Renton may be limited, the use of the mitigation bank for projects not requiring fisheries mitigation may be undesirable. This issue will be considered in evaluating this mitigation option. • Use of Wetland Mitigation Bank Site 1 as a mitigation option appears feasible. This site was originally rejected by the regulatory agencies because initial studies suggested a liner would be needed to establish adequate hydrology. However, hydrologic data, geotechnical analyses, and observations of adjacent wetlands suggest the "fatal flaw" of a lined wetland is unfounded. If this option is pursued, a strategy to present persuasive data showing that a liner is not required or is not a fatal will be needed. • A final mitigation option,not discussed with the City could include a combination of the above mitigation options coupled with wetland enhancement on City owned wetlands. Enhancement i- opportunities include conversion of lower quality reed canarygrass wetland habitat to shrub or forest wetland habitat,or enhancing forested wetland habitat with evergreen tree species such as red cedar and/or Sitka spruce. Additional enhancements to be incorporated into mitigation planning include wetland buffer enhancements. Buffer enhancements include planting buffer areas with evergreen trees and food producing shrubs to provide screening, cover, and forage for wildlife. If this option is viewed favorably by resource agencies it may provide a relatively low cost mitigation option because earthwork costs would be minimized.' APPROACH Parametrix identifies two tasks to complete the requested scope of work, as further described below. The overall approach in evaluating mitigation sites will be to review existing data and identify additional data needed (if needed) to augment and strengthen previous mitigation analyses. Upon collection of additional data , feasibility analysis would be completed to finalize a preferred mitigation option. The selection of a preferred plan would be completed with detailed review by r City of Renton staff and negotiations with resource agencies (US Army Corps of Engineers, US Fish and Wildlife Service, US Environmental Protection Agency, Muckleshoot Indian Tribe, National Marine Fisheries Service, Washington Department of Ecology, and Washington Department of Fish and Wildlife). The goal of this approach is successful approval of the Phase 2 Section 404 Permit application. Task 1-Evaluation of Potential Mitigation Options and Data Needs Purpose: This task will identify analysis criteria and data collection needs that will allow the benefits and approximate costs of each mitigation option to be compared. Based on this analysis and the results of agency coordination (Task 2), a recommendation regarding the preferred mitigation option will be made. Activities: Parametrix will review existing data for the potential mitigation options and identify additional data needed to evaluate the feasibility and potential costs of each mitigation project. Since it generally appears feasible to restore wetlands at each potential mitigation site, this effort will focus on developing conceptual plans, identifying general information needed to more accurately estimate project costs, organizing information to compare the three options, and to provide convincing design analysis(particularly relating to wetland hydrology)to reviewing agencies. ' Anticipated revisions to the Renton Wetland Ordinance will permit enhancement as a mitigation option when used in conjunction with wetland creation or restoration. 2 Additional data is assumed to be existing hydrologic monitoring data not previously incorporated into the mitigation analysis. City of Renton—Transportation Systems Oaksdale Avenue SW Extension Project Submitted by Parametrix,Inc. t- Phase 2 Wetland Mitigation 2 June 3, 1998 Data that may be needed to fully evaluate one or more mitigation options are: • Soils analysis to determine suitability for use as construction fill on other projects. • Limited spot elevation data on or near mitigation sites to define design elevations relative to natural wetlands. • Limited water level monitoring to evaluate wetland design criteria or assess construction dewatering issues. Analysis to be completed with existing and new data include: • Developing conceptual grading and habitat designs. • Estimating excavation requirements. • Evaluating hydrologic conditions and seasonal variations. • Estimating revegetation requirements and costs. If new data are needed to complete the analysis of the mitigation potential for each option, a workplan defining data collection methods will be prepared . Upon review and approval by the City, the plan will be implemented (alternatively, the City may choose to collect the additional data). Task 2-Agency Coordination Purpose: The purpose of this task is to coordinate with City departments and resource agencies to explain mitigation options and design approaches, solicit feedback, and ultimately select a preferred mitigation option. 3 Collection of new data is not included in this scope,since this data will be site specific(i.e.wetland delineation along the berm)and dependent upon selection of a preferred alternative. City of Renton—Transportation Systems Oaksdale Avenue SW Extension Project Submitted by Parametrix,Inc. t, Phase 2 Wetland Mitigation 3 June 3, 1998 Activities: Conceptual mitigation plans and feasibility analyses of mitigation options will be presented to resource agencies with review authority over the Corps of Engineers permit. Based on agency review and comments and City of Renton review, a preferred mitigation option will be selected. The intent of this coordination is to demonstrate responsiveness to the concerns and recommendations of reviewing agencies, and (if necessary), convince them that alternative approaches are valid. Coordination with agencies is expected to include initial telephone consultation to discuss the project and mitigation approach. An information packet would be prepared and circulated to agencies prior to an office and field presentation. Following the field meeting, additional meetings or telephone coordination would be conducted to inform agencies of new information or relevant decisions. It is especially important to meet with agencies prior to issuance of the public notice and early during the official comment period so that all agency questions arising from their review are proactively answered. DOCUMENTS TO BE FURNISHED BY THE CONSULTANT Technical Memorandum and Conceptual Mitigation Design The above analysis will be described in technical memoranda that summarizes a conceptual mitigation design and compares the ecological benefits and constraints for each mitigation option. The designs will incorporate mitigation features needed to meet agency requirements. A review of available hydrologic (surface and subsurface), geotechnical, and ecological data necessary to support the mitigation design will be included in the report. This review will identify data gaps and their significance to the probability of ultimately developing a successful mitigation plan. Additional data needed to finalize a mitigation design for each plan will also be listed. A workplan will be prepared to define data collection methods for obtaining information critical to the selection of a preferred option, if needed, and for obtaining information necessary for final mitigation design. Text documents are to be delivered on disk, in Microsoft Word 6.Oa for Windows format. Conceptual designs will be prepared on Auto Cad R14 using base map information from the City's GIS. Miscellaneous Additional information to be provided by the consultant includes records of telephone communications, minutes from agency meetings, and meeting materials (handouts and/or presentation boards).

Such payment shall be full compensation for all work performed or services rendered and for all labor, materials, equipment, and incidentals necessary to complete the work specified in Section II, "Scope of Work." The CONSULTANT shall conform with the applicable portion of 48 CFR 31. A. Actual Costs Payment for all consulting services for this project shall be on the basis of the CONSULTANT's actual cost plus a fixed fee. The actual cost shall include direct salary cost, overhead, and direct nonsalary cost. 1. Direct Salary Costs The direct salary cost is the direct salary paid to principals,professional,technical,and clerical personnel for the time they are productively engaged in work necessary to fulfill the terms of this AGREEMENT. 2. Overhead Costs Overhead costs are those costs other than direct costs which are included as such on the books of the CONSULTANT in the normal everyday keeping of its books. Progress payments shall be made at the rate shown in the heading of this AGREEMENT,under"Overhead Progress Payment Rate." Total overhead payment shall be based on the method shown in the heading of the AGREEMENT. The three options are explained as follows: a. Actual Cost Not To Exceed Maximum Percent: If this method is indicated in the heading of this AGREEMENT,the AGENCY agrees to reimburse the CONSULTANT at the actual overhead rate verified by audit up to the maximum percentage shown in the space provided. Final overhead payment when accumulated with all other actual costs shall not exceed the total maximum amount payable shown in the heading of this AGREEMENT. b. Fixed Rate: If this method is indicated in the heading of the AGREEMENT,the AGENCY agrees to reimburse the CONSULTANT for overhead at the percentage rate shown. This rate shall not change during the life of the AGREEMENT. A summary of the CONSULTANT's cost estimate and the overhead computation are attached hereto as Exhibit D-1 and by this reference made part of this AGREEMENT. When an Actual Cost method,or the Actual Cost Not To Exceed method is used, the CONSULTANT(prime and all subconsultants)will submit to the AGENCY within three months after the end of each firm's fiscal year, an overhead schedule in the format required by the AGENCY(cost category, dollar expenditures, etc.) for the purpose of adjusting the overhead rate for billing purposes. It shall be used for the computation of progress payments during the following year and for retroactively adjusting the previous year's overhead cost to reflect the actual rate. Failure to supply this information by either the prime consultant or any of the subconsultants shall cause the agency to withhold payment of the billed overhead costs until such time as the required information is received and an overhead rate for billing purposes is approved. t- The STATE and/or the Federal Government may perform an audit of the CONSULTANT's books and records at any time during regular business hours to determine the actual overhead rate, if they so desire. 3. Direct Nonsalary Costs Direct nonsalary costs will be reimbursed at the actual cost to the CONSULTANT. These charges may include,but are not limited to the following items: travel,printing, long distance telephone, supplies, computer charges, and fees of subconsultants. Air or train travel will only be reimbursed to economy class levels unless otherwise approved by the AGENCY. Automobile mileage for travel will be reimbursed at the current rate approved for AGENCY employees and shall be supported by the date and time of each trip with origin and destination of such trips. Subsistence and lodging expenses will be reimbursed at the same rate as for AGENCY employees. The billing for nonsalary cost, directly identifiable with the Project, shall be an itemized listing of the charges supported by copies of original bills, invoices, expense accounts, and miscellaneous supporting data retained by the CONSULTANT. Copies of the original supporting documents shall be provided to the AGENCY upon request. All of the above charges must be necessary for the services to be provided under this AGREEMENT. 4. Fixed Fee The fixed fee,which represents the CONSULTANT's profit, is shown in the heading of this AGREEMENT under Fixed Fee. This amount does not include any additional fixed fee which could be authorized from the Management Reserve Fund. This fee is based on the scope of work defined in this AGREEMENT and the estimated man-months required to perform the stated scope of work. In the event a supplemental agreement is entered into for additional work by the CONSULTANT, the supplemental agreement may include provisions for the added costs and an appropriate additional fee. The fixed fee will be prorated and paid monthly in proportion to the percentage of work completed by the CONSULTANT and reported in the monthly progress reports accompanying the invoices. Any portion of the fixed fee earned but not previously paid in the progress payments will be covered in the final payment, subject to the provisions of Section IX,Termination of Agreement. 5. Management Reserve Fund The AGENCY may desire to establish a Management Reserve Fund to provide the Agreement Administrator the flexibility of authorizing additional funds to the AGREEMENT for allowable unforeseen costs, or reimbursing the CONSULTANT for additional work beyond that already defined in this AGREEMENT. Such authorization(s) shall be in writing and shall not exceed the lesser of$50,000 or 10% of the Total Amount Authorized as shown in the heading of this AGREEMENT. The amount included for the Management Reserve Fund is shown in the heading of this agreement. This fund may be replenished in a subsequent supplemental agreement. Any changes requiring additional costs in excess of the"Management Reserve Fund" shall be made in accordance with Section XIV, "Extra Work." 6. Maximum Total Amount Payable The maximum total amount payable,by the AGENCY to the CONSULTANT under this AGREEMENT, shall not exceed the amount shown in the heading of this AGREEMENT. The Maximum Total Amount Payable is comprised of the Total Amount Authorized, which includes the Fixed Fee and the Management Reserve Fund. The Maximum Total Amount Payable does not include payment for extra work as stipulated in Section XIV, "Extra Work." ,, B. Monthly Progress Payments The CONSULTANT may submit invoices to the AGENCY for reimbursement of actual costs plus the calculated overhead and fee not more often than once per month during the progress of the work. Such invoices shall be in a format approved by the AGENCY and accompanied by the monthly progress reports required under Section III, General Requirements, of this AGREEMENT. The invoices will be supported by an itemized listing for each item including direct salary, direct nonsalary, and allowable overhead costs to which will be added the prorated Fixed Fee. To provide a means of verifying the invoiced salary costs for CONSULTANT employees, the AGENCY may conduct employee interviews. These interviews may consist of recording the names,titles, and present duties of those employees performing work on the PROJECT at the time of the interview. C. Final Payment Final payment of any balance due the CONSULTANT of the gross amount earned will be made promptly upon its verification by the AGENCY after the completion of the work under this AGREEMENT, contingent upon receipt of all PS&E,plans,maps,notes,reports, and other related documents which are required to be furnished under this AGREEMENT. Acceptance of such final payment by the CONSULTANT shall constitute a release of all claims for payment which the CONSULTANT may have against the AGENCY unless such claims are specifically reserved in writing and transmitted to the AGENCY by the CONSULTANT prior to its acceptance. Said final payment shall not,however,be a bar to any claims that the AGENCY may have against the CONSULTANT or to any remedies the AGENCY may pursue with respect to such claims. The payment of any billing will not constitute agreement as to the appropriateness of any item and that at the time of final audit, all required adjustments will be made and reflected in a final payment. In the event that such final audit reveals an overpayment to the CONSULTANT, the CONSULTANT will refund such overpayment to the AGENCY within ninety(90) days of notice of the overpayment. Such refund shall not constitute a waiver by the CONSULTANT for any claims relating to the validity of a finding by the AGENCY of overpayment. D. Inspection of Cost Records The CONSULTANT and the subconsultants shall keep available for inspection by representatives of the AGENCY and the United States, for a period of three years after final payment, the cost records and accounts pertaining to this AGREEMENT and all items related to or bearing upon these records with the following exception: if any litigation, claim, or audit arising out of, in connection with, or related to this contract is initiated before the expiration of the three-year period, the cost records and accounts shall be retained until such litigation, claim, or audit involving the records is completed.

I appreciate your request for a proposal from Parametrix to assist with the evaluation and selection of a preferred wetland mitigation option for the Phase 2 Oaksdale Avenue SW Extension Project. Based on our meeting, I understand the critical need to develop a mitigation plan that will successfully be permitted by the Corps of Engineers. Parametrix is well-qualified to perform this work as we have coordinated numerous wetland mitigation and permitting projects for street and other public works projects. Our recent or ongoing projects involving wetland mitigation,permitting,and agency coordination include the following: 0 Natural Resource Permitting and Mitigation Design for Seattle-Tacoma International Airport Master Plan Update,Port of Seattle(Barbara Hinkle,206-439-6606) • South 200d' Street/196h Street Improvements, City of Kent Engineering Department (Tim LaPorte,253-859-3593) • Everett-Seattle Commuter Rail Project, Regional Transit Authority (David Beal, 206- 689-3524) • 132d Street SE Extension, Snohomish County Department of Public Works (Lorna Smith,360-388-6406) • Sammamish River Habitat Improvements, City of Redmond (Cathy Beam, 206-556- 2429) • Third party review of wetland mitigation plans, City of Renton (Peter Rosen, 425-235- 2719) These projects are successful because of the depth of technical expertise and regulatory experience Parametrix Staff bring to them. I manage four wetland biologists, with Bachelors and Masters degrees in Botany, Aquatic Ecology, and Plant Biology. In addition, our wetlands team is supported by in-house fisheries biologists, hydrologists, geologists, survey teams, or design engineers who can assist in evaluating wetland mitigation feasibility and design. Parametrix' ability to efficiently perform interdisciplinary review of engineering and ecological issues assures our mitigation strategies are complete and meet agency requirements to provide multiple wetland functions. AInL Printed on Recvcled Paoer Key staff available to consult with the City of Renton on these issues include: • Clay Antieau(Botanist)-consults on issues related to native plant species selection, and control of invasive plants in mitigation sites. • William Kleindl(Aquatic Ecologist)-is expert in ecological analysis of wetlands and design of mitigation wetlands to mimic natural systems. • Bob Sullivan (Fisheries Biologist)-assists with incorporating fisheries habitat into wetland mitigation designs. He will be consulted on the design of Banking Site 2 to provide fisheries habitat. • Paul Fendt(P.E.)-assists biologists with engineering cost estimates and design for wetland and fisheries mitigation projects. • Ground and surface water hydrologists-assist with monitoring well installation, data collection, and hydrologic analyses. • Parametrix Survey Team-provides elevation and mapping of mitigation sites to create base maps needed to support mitigation designs. • Landscape architects-assist wetland biologists in designing wetland mitigation planting plans and bid specifications. In addition to having expert staff. Parametrix currently has several ongoing wetland mitigation and permitting projects that involve one or more of the same agency staff who will review and approve the wetland mitigation plan for Phase 2. During recent presentations to these individuals, we have established a strong rapport by outlining logical and ecologically valid project impact analyses, mitigation strategies, and mitigation design options. Our general approach to agency coordination (Task 2)will follow this model and take advantage of this favorable rapport. Since our discussion, I have visited the mitigation sites discussed. I also reviewed the JARPA application for the project, aerial photographs, topographic mapping, recent hydrologic data for the project area, and conceptual designs developed as part of the mitigation bank project. In conjunction with our work on the wetland mitigation bank project, we have measured the bankfull water level and recent flood elevations on Springbrook Creek adjacent to Mitigation Site 2. Based on this review, as further explained in our proposal, we believe all options present viable mitigation opportunities to compensate for filling 1 acre of wetland on the Phase 2 project. Because of this preliminary conclusion,our proposed work for Task I(Evaluation of Mitigation Options)focuses on re-evaluating existingdata relare to the mitigation needs of this project. Limited additional data O/' kC.CMrA ti may be needed �Aestimate potenral construction costs and to further demonstrate the feasibility of certain wetland mitigation options to the review agencies. �� ""�"'F f I I 6 ► P`f` 4-c c_l['�J t4& d4" cv Ja we wa"'f d�if n/ f� ��t� I t 4.,,+ W qld "Mu" A 1,714��, In summary, Parametrix offers qualified staff with diverse consulting experience to address the variety of regulatory, ecological, and engineering issues that are required to successfully complete Co e�r� the mitigation permitting and planning for the Oaksdale Avenue project.

Phase Z Wetland Mitigation 2 March 13, 1998 PROPOSAL CITY OF RENTON OAKSDALE AVENUE SW EXTENSION—PHASE 2 EVALUATE WETLAND NIITIGATION OPTIONS AND NEGOTIATE WITH AGENCIES Parametrix,Inc. Kirkland,Washington 98033 UNDERSTANDING The City of Renton received a Clean Water Act Section 404 Permit to fill wetlands associated with the Oaksdale Avenue SW Extension Phase I project. A Permit for Phase 2 of the project was specifically denied, pending development of a suitable wetland mitigation plan. Approval of Phase 2 under Section 404 will require a permit application, public notice, and supporting documents, including wetland mitigation(2 acres). Potential mitigation options for Phase 2 wetland impacts are as follows: • Removal of fill from City of Renton property located south of SW 27"' Street and east of Oaksdale Avenue. This option would allow restoration of about 2 acres of wetland. Establishment of wetlands with in this area would mitigate for impacts in proximity to the project. This restoration project could be designed to avoid removing most trees rooted near the edge of the fill,which would enhance the net habitat benefits of the project. Since there appears to be about a I foot drop in surface water elevation across the existing fill, it may be desirable to replace the existing culvert with a weir type structure to avoid hydrologic impacts to wetlands located west of the fill. A weir control structure would reduce the likelihood that clogging of the culvert would affect wetlands or adjacent property. • Use of the wetland mitigation bank Site 2, adjacent to Springbrook Creek offers significant mitigation potential for impacts associated with the Oaksdale Avenue project. It would allow in-kind replacement of shrub, ent, and forested wetland habitat, as well as allow out-of- kind mitigation such as fis f itat enhancement. However, since fisheries enhancement opportunities in Renton may be limited,the use of the mitigation bank for projects not requiring fisheries mitigation may be undesirable. This issue will be considered in evaluating this mitigation option. • Use of wetland mitigation bank Site 1 as a mitigation option appears feasible. This site was originally rejected by the regulatory agencies because initial studies suggested a liner would be needed to establish adequate hydrology. However, hydrologic data, geotechnical analyses, and observations of adjacent wetlands suggest the "fatal flaw" of a lined wetland is unfounded. If this option is pursued, a strategy to present persuasive data showing that a liner is not required will be needed. A % v �/Aw City of Renton—Transportation Systems Oaksdale Avenue SW Extension Project Submitted by Parametrix,Inc. Phase 2 Wetland Mitigation 3 March 13, 1998 r • A final mitigation option, not discussed with the City could include a combination of the above mitigation options coupled with wetland enhancement on City owned wetlands. Enhancement opportunities include conversion of lower quality reed canarygrass wetland habitat to shrub or forest wetland habitat,or enhancing forested wetland habitat with evergreen tree species such as red cedar and/or Sitka spruce. Additional enhancements to be incorporated into mitigation planning include wetland buffer enhancements. Buffer enhancements include planting buffer areas with evergreen trees and food producing shrubs to provide screening, cover, and forage for wildlife. If this option is viewed favorably by resource agencies rcquirefftents, it may provide a relatively low cost mitigation option because earthwork costs would be minimized. APPROACH Ord) ,�tnce .
