October 9,2019 During the term of this Contract,Perteet,Inc.(CONSULTANT)will perform professional services for the City of Renton(CITY),as detailed below: INTRODUCTION The project will construct improvements to extend Park Avenue N from the existing intersection with Logan Avenue N northward to connect to the Southport site now under construction.The purpose of the roadway extension is to provide a connection to the Southport development and relieve congestion on Lake Washington Boulevard. GENERAL SCOPE OF SERVICES This supplement is to support BNSF permitting requirements using services from Abeyta&Associates.Abeyta& Associates will perform an appraisal for the limits of the crossing permit. Additionally,this supplement is to provide geotechnical explorations by HWA GeoSciences Inc.at the BSNF trestle area of the project,which is north of the Lake Washington Boulevard N intersection with N Southport Drive,and incorporate findings at that location into the final geotechnical report. Currently only local agency funds will be used in the planning,design,and/or construction of the project.The CONSULTANT will use procedures outlined in the WSDOT Local Agency Guidelines(LAG Manual)during development of the project. OPTIONAL SERVICES The CONSULTANT may be asked by the CITY to provide optional services.Optional services that may be performed include: • Assistance with preparation of environmental documentation and permits • Assistance with preparation of grant funding packages • Assistance during Bidding for Boeing contract • Services during Construction Providing optional services will require a supplement to this agreement. TIME FOR COMPLETION No change to the current contract. Task 4—Right-of-Way Acquisition Task 4 is supplemented with the following: • 4.4 BNSF Appraisal 1 File location:X:\Renton,City of\Projects\20160266-N Park Ave Extension\Project Management\Contract\Contract Negotiations\Supplement#10- BNSF Permitting and Trestle Geotechnicol\Park Ave N Ext Scope and Fee-Supp#10-2019-09-25.doc PARK AVENUE N EXTENSION—BNSF EASEMENT ACQUISITION AND TRESTLE GEOTECHNICAL Agreement with Perteet Inc. October 9,2019 ABEYTA will prepare an appraisal for the Park Avenue N Extension crossing permit limits within BSNF right-of- way.The CONSULTANT will coordinate with ABEYTA during this process and anticipates up to two(2) meetings will be required specifically for this right-of-way negotiation,each lasting up to four(4)hours.

Task 5—Geotechnical Engineering Services Task 5 is supplemented with the following: 5.5 Trestle-Area Exploration (Geotechnical Boring) • Plan Field Exploration Program:HWA will plan and coordinate a geotechnical exploration program for the project.The program will consist of conducting one(1)geotechnical boring in the trestle-area of the project at the existing driveway shown in Figure 1,on the following page,in support of retaining wall design,luminaire foundation design,and identification of potentially compressible soil deposits that could affect the proposed sidewalk and trail.Planning will include identification of the location of the geotechnical boring and coordination of required equipment and utility clearance.The exploration will not close any portion of Lake Washington Boulevard N at any time.The exploration will be performed within the existing asphalt pavement of the driveway. • Conduct Utility Locates for Geotechnical Explorations:Prior to generating the geotechnical work plan, HWA will mark the proposed exploration locations and arrange for utility locates using the Utility Notification Center for the trestle-area exploration. • Conduct Exploration(Geotechnical Boring):HWA will conduct one(I)geotechnical boring in the trestle area to assess the subsurface soil conditions. The geotechnical boring will be conducted in the existing driveway pavement area.The geotechnical boring will be drilled during the day-time hours of 9am to 3pm with appropriate traffic control measures.The boring will be drilled to an approximate depth of 40' below ground surface.Boreholes will be patched with rapid-setting Portland cement concrete.Traffic control to consist of a coned off work area for both coring and pavement patching by subcontractor. Flaggers will not be required. The geotechnical boring will be logged by an HWA geotechnical engineer or HWA engineering geologist. HWA will patch the boring conducted through the pavement with quick drying concrete upon completion of the boring. • Generate Boring Logs and Assign Laboratory Testing:HWA will prepare a summary boring log and perform laboratory testing to evaluate relevant physical properties of the site soils.Laboratory testing 2 File location: X:\Renton,City of\Projects\20160266-N Park Ave Extension\Project Management\Contract\Contract Negotiations\Supplement#10- ENV Permitting and Trestle Geotechnical\Park Ave N Ext Scope and Fee-Supp#10-2019-09-25.doc PARK AVENUE N EXTENSION—BNSF EASEMENT ACQUISITION AND TRESTLE GEOTECHNICAL Agreement with Perteet Inc.
