The Contractor’s request shall list the specific items of work that remain to be completed in order to reach physical completion. The Engineer will schedule an inspection of the Work with the Contractor to determine the status of completion. The Engineer may also establish the Substantial Completion Date unilaterally.

The Contracting Agency must have full and unrestricted use and benefit of the facilities both from the operational and safety standpoint. 2. Only minor incidental Work, replacement of temporary substitute facilities, or correction of repair Work remains to reach physical completion of the Work. If after this inspection, the Engineer concurs with the Contractor that the Work is substantially complete and ready for its intended use, the Engineer, by written notice to the Contractor, will set the Substantial Completion Date. If, after this inspection the Engineer does not consider the Work substantially complete and ready for its intended use, the Engineer will, by written notice, so notify the Contractor giving the reasons therefore. Upon receipt of written notice concurring in or denying substantial completion, whichever is applicable, the Contractor shall pursue vigorously, diligently and without unauthorized interruption, the Work necessary to reach Substantial and Physical Completion. The Contractor shall provide the Engineer with a revised schedule indicating when the Contractor expects to reach substantial and physical completion of the Work. The above process shall be repeated until the Engineer establishes the Substantial Completion Date and the Contractor considers the Work physically complete and ready for Final Inspection. 1-05.11(2) Final Inspection and Physical Completion Date When the Contractor considers the Work physically complete and ready for Final Inspection, the Contractor, by Written Notice, shall request the Engineer to schedule a final inspection.

If the inspection is by another authority than the Engineer, the Contractor shall give the Engineer a minimum of 3 working days’ notice of the date fixed for such inspection. Required certificates of inspection by other authority than the Engineer shall be secured by the Contractor. It is the intent of the Contracting Agency to have at the Physical Completion Date a complete and operable system. Therefore, when the Work involves the installation of machinery or other mechanical equipment; street lighting, electrical distribution or signal systems; irrigation systems; buildings; or other similar Work, it may be desirable for the Engineer to have the Contractor operate and test the Work for a period of time, after final inspection but prior to the physical completion date. Whenever items of Work are listed in the Contract Provisions for operational testing they shall be fully tested under operating conditions for the time period specified to ensure their acceptability prior to the Physical Completion Date. During and following the test period, the Contractor shall correct any items of workmanship, materials, or equipment which prove faulty, or that are not in first class operating condition. Equipment, electrical controls, meters, or other devices and equipment to be tested during this period shall be tested under the observation of the Engineer, so that the Engineer may determine their suitability for the purpose for which they were installed. The Physical Completion Date cannot be established until testing and corrections have been completed to the satisfaction of the Engineer. The costs for power, gas, labor, material, supplies, and everything else needed to successfully complete operational testing, shall be included in the unit contract prices related to the system being tested, unless specifically set forth otherwise in the proposal.

The WUPP shall be prepared by and bear the seal and signature of a Professional Engineer licensed in the state of Washington. The WUPP shall comply with the Standard Specifications, as modified, or supplemented by the Amendments to the Standard Specifications and Special Provisions. The WUPP shall be reviewed and approved by the Engineer prior to any work in the vicinity of the Water utility pipe(s). The Engineer’s review of the submitted material shall in no way relieve the Contractor of the responsibility for making a satisfactory installation meeting the requirements of these documents and the utility owner. The Contractor is responsible for implementation of the approved WUPP. If deviations from the WUPP are necessary because of field conditions, the contractor must submit a revised submittal WUPP to the City for review. Excavation adjacent to water mains cannot proceed until the submittal is approved. The Contractor shall do the following: • Protect the existing water main, including valves, fittings, thrust blocks, coatings, during the course of construction. • Support the exposed water main to prevent any movement. • Use care to avoid damaging the existing water main with mechanical construction equipment. Chains and/or wire rope will not be allowed to support exposed water mains. Use double straps to support both sides of an exposed joint. Provide a compaction plan for backfill installed under exposed water lines and facilities. If Controlled Density Fill (CDF) has been approved for use as backfill around water mains, installation shall conform with the Project Plans and Standard Specifications, as modified or supplemented by the Amendments to the Standard Specifications and Special Provisions. • If, during construction, the structural integrity of the water line is compromised, stop construction and immediately notify the City Inspector to coordinate efforts to mitigate and rectify the situation. Requirements for Open Excavations Open Excavations Parallel to City of Renton Water Mains If the water main is located above the bottom of the construction excavation within the zone of influence— 1.5H: 1V slope from the bottom of the construction excavation, or the water main is within 5 feet of the excavation—the following shall apply: • Excavation adjacent to transmission mains (all sizes), conduits, and distribution mains ≥12 inches will require plans and associated structural and geotechnical calculations prepared and stamped/sealed by a Professional Engineer licensed in the state of Washington. 1-07 Legal Relations and Responsibilities to the Public City of Renton 1-46 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid • Excavations adjacent to distribution mains <12 inches may require plans and associated structural and geotechnical calculations prepared and stamped/sealed by a Professional Engineer licensed in the state of Washington as determined by City. • No more than 8 feet of parallel trench shall remain unsupported. • Minimize duration of unsupported trench walls. No section shall be left unsupported overnight or if groundwater is observed. • Supported sections of trench shall have positive-pressure shoring or shielded shoring backfilled between the trench wall and the shoring box. Positive-pressure shoring is defined as a system providing support to the trench wall, such that no ground movement adjacent to and within the excavated trench is possible. Positive-pressure shoring can be achieved with hydraulic jacks or by ensuring zero clearance between the shielded shoring and the trench wall. • Positive-pressure shoring is required at all water main bends and tees, to prevent undermining of the thrust-restraint systems. No amount of unsupported trench is permitted at these locations. Open Excavations Askew and Perpendicular to City of Renton Water Mains For open excavations askew and perpendicular to City of Renton water main, if the construction excavation is 5 feet or more below a >12-inch water main, or if the excavated trench is 6 feet or wider, then the following shall apply: • Show plans and associated structural and geotechnical calculations prepared and stamped/sealed by a Professional Engineer licensed in the state of Washington for any support beams, columns, steel plate foundation supports, blocking, and length of beams on each side of trench and columns.

Utility Potholing Potholing may be included as a bid item for use in determining the location of existing utilities in advance of the Contractor's operations. If potholing is not included as a bid item then it shall be considered incidental to other Work. The Contractor shall submit all potholing requests to the Engineer for approval, at least 2 working days before potholing is scheduled. Additionally, the Contractor shall provide potholing at the Engineer's request. In no way shall the Work described under Utility Potholing relieve the Contractor of any of the responsibilities described in Section 1-07.17 of the Standard Specifications and Special Provisions, and elsewhere in the Contract Documents. 1-07.17(3) Site Specific Potholing (******) This is a new section as follows: Site Specific Potholing is intended to be additional potholing as identified in the Plans or as directed by the Engineer, which is separate from and in addition to potholing included as incidental for utility installation. The Contractor shall perform exploratory excavations (potholing) as required to collect as-built information and verify the depth, location, size, and 1-07 Legal Relations and Responsibilities to the Public City of Renton 1-48 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid material of existing underground utilities at the identified locations. The Contractor shall perform all potholing identified on the plans prior to any construction to allow for any potential design modifications. The Contractor is still responsible to verify depth, location, alignment, and size of all existing utilities either specifically called for or not on the plans. The Contractor shall immediately notify the Engineer if field conditions differ from the expected conditions shown in the Contract Drawings. For these utilities, the Contractor shall allow the engineer 10 working days after written results are received to allow for minor design modification as necessary. The Contractor shall use the information obtained by potholing for procurement of suitable materials to revise the work accordingly, where required by the Contract. Upon completion of the excavation, the material can be used for temporary restoration if the material is satisfactory and with prior authorization from the Engineer. Where underground utilities are found to be in the way of construction, such condition shall not be deemed to be a changed or differing site condition, and if necessary, pipe alignment or grade shall be modified. No payment will be made unless potholing has been performed prior to trench excavation and witnessed by the Engineer or City Inspector. Different utilities may be found to occupy a common trench. Any two or more utilities separated by 3 feet or less shall constitute one locate. Where multiple utilities exist in close proximity, the Contractor shall be paid for one locate for every 5 feet of exploration trench. The quantity for this item is included to provide a common proposal for bid purposes. The actual quantity used in construction may vary from that amount. The unit price will not be adjusted if the actual quantity used varies by more than 25 percent. The contractor shall perform for this potholing a minimum of twenty working days prior to crossing to allow for potential revisions. The contractor shall not have cause for claim of down-time or any other additional costs associated with ‘waiting’ if the owner provides design revisions (related to the information supplied per this section) within ten working days after the contractor provides the surveyed elevations. In no way shall the Work described under Site Specific Potholing relieve the Contractor of any of the responsibilities described in Section 1-07.17 of the Standard Specifications and Special Provisions, and elsewhere in the Contract Documents. Measurement and Payment for Site Specific Potholing shall be per section 1-09.14(2)A4. 1-07.17(4) Interruption of Services (******) This is a new section as follows: Whenever in the course of the construction operation it becomes necessary to cause an outage of utilities, it shall be the Contractor's responsibility to notify the affected users and the Engineer not less than 48 hours in advance of such outage. The Contractor shall make reasonable effort to minimize the duration of outages, and shall estimate the length of time service will be interrupted and so notify the users. In the case of any utility outage that has exceeded or will exceed four hours, user contact shall again be made. Temporary service, if needed, will be arranged by the Contractor at no cost to the Owner. Water service interruptions, shut-offs, and connection shall be in accordance with Section 7-09. 1-07 Legal Relations and Responsibilities to the Public City of Renton 1-49 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid Overhead lighting outages shall not exceed 24 hours.

In the event an outage or service interruption is caused by Contractor negligence or unmarked utility, the Contractor shall notify and coordinate with the owner of the utility and the Engineer immediately. The Contractor shall also be responsible for notifying the affected users as soon as possible and no later than 8 hours after the interruption occurred. The Contractor will be responsible for any negligence and reparations necessary to resolve the interruption. No additional compensation will be made to the Contractor for reason of delay caused by the actions of any utility company, and the Contractor shall consider such costs to be incidental to the other items of the Contract. 1-07.17(5) Resolution of Utility Conflicts (******) This is a new section as follows: In no way shall the work described under “Resolution of Utility Conflicts” relieve Contractor of any of the responsibilities described in Section 1-07.17 of the Standard Specifications and Special Provisions, and elsewhere in the Contract Documents. If or when utility conflicts occur, Contractor shall continue the construction process on other aspects of the project whenever possible. If “Resolution of Utility Conflicts” is included as a bid item in Section 1-09.14, it shall be used to resolve any new identified utility conflicts not otherwise shown on the Contract Drawing or Specifications that are identified during the course of construction. 1-07.18 Public Liability and Property Damage Insurance (******) Delete this section in its entirety, and replace it with the following: 1-07.18 Insurance (December 30, 2022 APWA GSP) 1-07.18(1) General Requirements A.

Should a bid item be listed in a “Payment” clause but not in the Proposal Form, and Work for that item is performed by the Contractor and the Work is not stated as included in or incidental to a pay item in the Contract and is not Work that would be required to complete the intent of the Contract per Section 1-04.1, then payment for that Work will be made as for Extra Work pursuant to a Change Order. 1-09 Measurement and Payment City of Renton 1-70 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid The words “Bid Item,” “Contract Item,” and “Pay Item,” and similar terms used throughout the Contract Documents are synonymous. If the “payment” clause in the Specifications relating to any unit bid item price in the Proposal Form requires that said unit bid item price cover and be considered compensation for certain Work or material essential to the item, then the Work or material will not be measured or paid for under any other unit bid item which may appear elsewhere in the Proposal Form or Specifications. Pluralized unit bid items appearing in these Specifications are changed to singular form. Payment for bid items listed or referenced in the “Payment” clause of any particular section of the Specifications shall be considered as including all of the Work required, specified, or described in that particular section. Payment items will generally be listed generically in the Specifications, and specifically in the bid form. When items are to be “furnished” under one payment item and “installed” under another payment item, such items shall be furnished FOB project site, or, if specified in the Special Provisions, delivered to a designated site. Materials to be “furnished,” or “furnished and installed” under these conditions, shall be the responsibility of the Contractor with regard to storage until such items are incorporated into the Work or, if such items are not to be incorporated into the Work, delivered to the applicable Contracting Agency storage site when provided for in the Specifications. Payment for material “furnished,” but not yet incorporated into the Work, may be made on monthly estimates to the extent allowed. 1-09.6 Force Account (December 30, 2022 APWA GSP) Supplement this section with the following: The Contracting Agency has estimated and included in the Proposal, dollar amounts for all items to be paid per force account, only to provide a common proposal for Bidders. All such dollar amounts are to become a part of Contractor's total bid. However, the Contracting Agency does not warrant expressly or by implication, that the actual amount of work will correspond with those estimates. Payment will be made on the basis of the amount of work actually authorized by the Engineer. 1-09.7 Mobilization (******) Supplement this section as follows: Mobilization shall also include, but not be limited to, the following items: the movement of Contractor's personnel, equipment, supplies, and incidentals to the project site; the establishment of an office, buildings, and other facilities necessary for Work on the project; providing sanitary facilities for the Contractor's personnel; and obtaining permits or licenses required to complete the project not furnished by the Owner. Payment will be made for the following bid item(s): “Mobilization & Demobilization,” Lump Sum. 1-09 Measurement and Payment City of Renton 1-71 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid 1-09.9 Payments (December 30, 2022 APWA GSP) Section 1-09.9 is revised as follows: The basis of payment will be the actual quantities of Work performed according to the Contract and as specified for payment. The Contractor shall submit a breakdown of the cost of lump sum bid items at the Preconstruction Conference, to enable the Project Engineer to determine the Work performed on a monthly basis. A breakdown is not required for lump sum items that include a basis for incremental payments as part of the respective Specification. Absent a lump sum breakdown, the Project Engineer will make a determination based on information available. The Project Engineer’s determination of the cost of work shall be final. Progress payments for completed work and material on hand will be based upon progress estimates prepared by the Engineer. A progress estimate cutoff date will be established at the preconstruction conference. The initial progress estimate will be made not later than 30 days after the Contractor commences the work, and successive progress estimates will be made every month thereafter until the Completion Date. Progress estimates made during progress of the work are tentative, and made only for the purpose of determining progress payments. The progress estimates are subject to change at any time prior to the calculation of the final payment. The value of the progress estimate will be the sum of the following: 1. Unit Price Items in the Bid Form — the approximate quantity of acceptable units of work completed multiplied by the unit price. 2. Lump Sum Items in the Bid Form — based on the approved Contractor’s lump sum breakdown for that item, or absent such a breakdown, based on the Engineer’s determination. 3. Materials on Hand — 100 percent of invoiced cost of material delivered to Job site or other storage area approved by the Engineer. 4. Change Orders — entitlement for approved extra cost or completed extra work as determined by the Engineer. Progress payments will be made in accordance with the progress estimate less: 1. Retainage per Section 1-09.9(1), on non FHWA-funded projects; 2. The amount of progress payments previously made; and 3. Funds withheld by the Contracting Agency for disbursement in accordance with the Contract Documents. Progress payments for work performed shall not be evidence of acceptable performance or an admission by the Contracting Agency that any work has been satisfactorily completed. The determination of payments under the contract will be final in accordance with Section 1--05.1. 1-09 Measurement and Payment City of Renton 1-72 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid Failure to perform obligations under the Contract by the Contractor may be decreed by the Contracting Agency to be adequate reason for withholding any payments until compliance is achieved. Upon completion of all Work and after final inspection (Section 1-05.11), the amount due the Contractor under the Contract will be paid based upon the final estimate made by the Engineer and presentation of a Final Contract Voucher Certification to be signed by the Contractor. The Contractor's signature on such voucher shall be deemed a release of all claims of the Contractor unless a Certified Claim is filed in accordance with the requirements of Section 1-09.11 and is expressly excepted from the Contractor’s certification on the Final Contract Voucher Certification. The date the Contracting Agency signs the Final Contract Voucher Certification constitutes the final acceptance date (Section 1-05.12). If the Contractor fails, refuses, or is unable to sign and return the Final Contract Voucher Certification or any other documentation required for completion and final acceptance of the Contract, the Contracting Agency reserves the right to establish a Completion Date (for the purpose of meeting the requirements of RCW 60.28) and unilaterally accept the Contract. Unilateral final acceptance will occur only after the Contractor has been provided the opportunity, by written request from the Engineer, to voluntarily submit such documents. If voluntary compliance is not achieved, formal notification of the impending establishment of a Completion Date and unilateral final acceptance will be provided by email with delivery confirmation from the Contracting Agency to the Contractor, which will provide 30 calendar days for the Contractor to submit the necessary documents. The 30 calendar day period will begin on the date the email with delivery confirmation is received by the Contractor. The date the Contracting Agency unilaterally signs the Final Contract Voucher Certification shall constitute the Completion Date and the final acceptance date (Section 1-05.12). The reservation by the Contracting Agency to unilaterally accept the Contract will apply to Contracts that are Physically Completed in accordance with Section 1-08.5, or for Contracts that are terminated in accordance with Section 1-08.10. Unilateral final acceptance of the Contract by the Contracting Agency does not in any way relieve the Contractor of their responsibility to comply with all Federal, State, tribal, or local laws, ordinances, and regulations that affect the Work under the Contract. Payment to the Contractor of partial estimates, final estimates, and retained percentages shall be subject to controlling laws. (******) Supplement this section as follows: Applications for payment shall be itemized and supported to the extent required by the Engineer by receipts or other vouchers showing payment for materials and labor, payments to subcontractors, and other such evidence of the Contractor's right to payment as the Engineer may direct, including “red line” as-built drawings showing work installed by the contractor during the progress payment period. The Contractor shall submit a progress report with each monthly request for a progress payment. The progress report shall indicate the estimated percent complete for each activity listed on the progress schedule (see Section 1-08.3) and a revised and updated schedule to reflect the most current project completion date. 1-09 Measurement and Payment City of Renton 1-73 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid 1-09.9(1) Retainage (******) Section 1-09.9(1) is supplemented as follows: The retained amount shall be released as stated in the Standard Specifications if no claims have been filed against such funds as provided by law, and if the Owner has no unsatisfied claims against the Contractor. In the event claims are filed, the Owner shall withhold, until such claims are satisfied, a sum sufficient to satisfy all claims and to pay attorney's fees. In addition, the Owner shall withhold such amount as is required to satisfy any claims by the Owner against the Contractor, until such claims have been finally settled. Neither the final payment nor any part of the retained percentage shall become due until the Contractor, if requested, delivers to the Owner a complete release of all liens arising out of this Contract, or receipts in full in lieu thereof, and, if required in either case, an affidavit that so far as the Contractor has knowledge or information, the release and receipts include all labor and materials for which a lien could be filed: but the Contractor may, if any subcontractor refuses to furnish a release or receipt in full, furnish a bond satisfactorily to the Engineer to indemnify the Owner against the lien. If any lien remains unsatisfied after all payments are made, the Contractor shall reimburse to the Owner all monies that the latter may be compelled to pay in discharging such lien, including all costs and reasonable engineer's and attorney's fees. 1-09.9(2) Contracting Agency’s Right to Withhold and Disburse Certain Amounts (******) This is a new section as follows: In addition to monies retained pursuant to RCW 60.28 and subject to RCW 39.04.250, RCW 39.12, and RCW 39.76; the Contractor authorizes the Engineer to withhold progress payments due, or deduct an amount from any payment or payments due the Contractor which, in the Engineer’s opinion, may be necessary to cover the Contracting Agency’s costs for or to remedy the following situations: Damage to another contractor when there is evidence thereof and a claim has been filed. Where the Contractor has not paid fees or charges to public authorities of municipalities, which the Contractor is obligated to pay. Utilizing material tested and inspected by the Engineer, for purposes not connected with the Work (Section 1-05.6). Landscape damage assessments per Section 1-07.16. For overtime Work performed by City personnel per Section 1-08.0(3). Anticipated or actual failure of the Contractor to complete the Work on time: a. Per Section 1-08.9 Liquidated Damages; or b. Lack of construction progress based upon the Engineer’s review of the Contractor’s approved progress schedule, which indicates the Work will not be complete within the contract time. When calculating an anticipated time overrun, the Engineer will make allowances for weather delays, approved unavoidable delays, and suspensions of the Work. The amount withheld under this subparagraph will be based upon the liquidated damages amount per day set 1-09 Measurement and Payment City of Renton 1-74 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid forth in Contract Documents multiplied by the number of days the Contractor’s approved progress schedule, in the opinion of the Engineer, indicates the Contract may exceed the Contract Time. Failure of the Contractor to perform any of the Contractor’s other obligations under the Contract, including but not limited to: a. Failure of the Contractor to provide the Engineer with a field office when required by the Contract Provisions. b. Failure of the Contractor to protect survey stakes, markers, etc., or to provide adequate survey Work as required by Section 1-05.4. c. Failure of the Contractor to correct defective or unauthorized Work (Section 1- 05.7). d.

Failure of the Contractor to pay worker’s benefits (Title 50 and Title 51 RCW) as required by Section 1-07.10. g. Failure of the Contractor to submit and obtain approval of a progress schedule per Section 1-08.3. The Contractor authorizes the Engineer to act as agent for the Contractor disbursing such funds as have been withheld pursuant to this Section to a party or parties who are entitled to payment. Disbursement of such funds, if the Engineer elects to do so will be made only after giving the Contractor 15 calendar days prior written notice of the Contracting Agency’s intent to do so, and if prior to the expiration of the 15-calendar day period, No legal action has commenced to resolve the validity of the claims, and The Contractor has not protested such disbursement. A proper accounting of all funds disbursed on behalf of the Contractor in accordance with this Section will be made. A payment made pursuant to this section shall be considered as payment made under the terms and conditions of the Contract. The Contracting Agency shall not be liable to the Contractor for such payment made in good faith. 1-09.9(3) Final Payment (******) This is a new section as follows: Upon Acceptance of the Work by the Contracting Agency, the final amount to be paid the Contactor will be calculated based upon a Final Progress Estimate made by the Engineer. Acceptance by the Contractor of the final payment shall be and shall operate as a release: 1. To the Contracting Agency of all claims and all liabilities of the Contractor, other than claims in stated amounts as may be specifically excepted in writing by the Contractor; 2. For all things done or furnished in connection with the Work; 1-09 Measurement and Payment City of Renton 1-75 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid 3. For every act and neglect by the Contracting Agency; and 4. For all other claims and liability relating to or arising out of the Work. A payment (monthly, final, retainage, or otherwise) shall not release the Contractor or the Contractor’s Surety from any obligation required under the terms of the Contract Documents or the Contract Bond; nor shall such payment constitute a waiver of the Contracting Agency’s ability to investigate and act upon findings of non-compliance with the WMBE requirements of the Contract; nor shall such payment preclude the Contracting Agency from recovering damages, setting penalties, or obtaining such other remedies as may be permitted by law. Before the Work will be accepted by the Contracting Agency, the Contractor shall submit an affidavit, on the form provided by the Engineer, of amounts paid to certified disadvantaged (DB), minority (MBE) or women business enterprises (WBE) participating in the Work. Such affidavit shall certify the amounts paid to the DB, MBE or WBE subcontractors regardless of tier. On federally funded projects the Contractor may also be required to execute and furnish the Contracting Agency an affidavit certifying that the Contractor has not extended any loans, gratuity or gift and money pursuant to Section 1-07.19 of these Specifications. If the Contractor fails, refuses, or is unable to sign and return the Final Progress Estimate or any other documents required for the final acceptance of the Contract, the Contracting Agency reserves the right to establish a completion date and unilaterally accept the Contract. Unilateral acceptance will occur only after the Contractor has been provided the opportunity, by written request from the Engineer, to voluntarily submit such documents. If voluntary compliance is not achieved, formal notification of the impending unilateral acceptance will be provided by certified letter from the Engineer to the Contractor that will provide 30 calendar days for the Contractor to submit the necessary documents. The 30- calendar day deadline shall begin on the date of the postmark of the certified letter from the Engineer requesting the necessary documents. This reservation by the Contracting Agency to unilaterally accept the Contract will apply to contracts that are completed in accordance with Section 1-08.5 for contracts that are terminated in accordance with Section 1-08.10. Unilateral acceptance of the Contract by the Contracting Agency does not in any way relieve the Contractor of the provisions under contract or of the responsibility to comply with all laws, ordinances, and federal, state, and local regulations that affect the Contract.

A lot is defined as the total quantity of material or work produced for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to one day’s production or 800 tons, whichever is less except that the final sublot will be a minimum of 400 tons and may be increased to 1200 tons. All of the test results obtained from the acceptance samples from a given lot shall be evaluated collectively. If the Contractor requests a change to the JMF that is approved, the material produced after the change will be evaluated on the basis of the new JMF for the remaining sublots in the current lot and for acceptance of subsequent lots. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the Engineer is satisfied that material conforming to the Specifications can be produced. Sampling and testing for evaluation shall be performed on the frequency of one sample per sublot. 5-04.3(9)C2 Mixture Nonstatistical Evaluation Sampling Samples for acceptance testing shall be obtained by the Contractor when ordered by the Engineer.

Testing for compliance of asphalt binder content will be by WSDOT FOP for AASHTO T 308. Testing for compliance of gradation will be by FOP for WAQTC T 27/T 11. 5-04.3(9)C4 Mixture Nonstatistical Evaluation – Pay Factors For each lot of material falling outside the tolerance limits in 5-04.3(9), the Contracting Agency will determine a Composite Pay Factor (CPF) using the following price adjustment factors: Table of Price Adjustment Factors Constituent Factor “f” All aggregate passing: 1½”, 1”, ¾”, ½”, ⅜” and No. 4 sieves 2 All aggregate passing No. 8 sieve 15 All aggregate passing No. 200 sieve 20 Asphalt binder 40 Air Voids (Va) (where applicable) 20 Each lot of HMA produced under Nonstatistical Evaluation and having all constituents falling within the tolerance limits of the job mix formula shall be accepted at the unit Contract price with no further evaluation. When one or more constituents fall outside the nonstatistical tolerance limits in the Job Mix Formula shown in Table of Price Adjustment Factors, the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The nonstatistical tolerance limits will be used in the calculation of the CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or samples from the Roadway shall be tested to provide a minimum of three sets of results for evaluation. 5-04.3(9)C5 Vacant 5-04.3(9)C6 Mixture Nonstatistical Evaluation – Price Adjustments For each lot of HMA mix produced under Nonstatistical Evaluation when the calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The total job mix compliance price adjustment will be calculated as the product of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. If a constituent is not measured in accordance with these Specifications, its individual pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 5-04 Hot Mix Asphalt City of Renton 1-145 April 2024 Burnett Ave S and Williams Ave S Storm System Improvements Issued for Bid 5-04.3(9)C7 Mixture Nonstatistical Evaluation – Retests The Contractor may request a sublot be retested. To request a retest, the Contractor shall submit a written request within 7 calendar days after the specific test results have been received. A split of the original acceptance sample will be retested. The split of the sample will not be tested with the same tester that ran the original acceptance test. The sample will be tested for a complete gradation analysis, asphalt binder content, and, at the option of the agency, Va. The results of the retest will be used for the acceptance of the HMA in place of the original sublot sample test results. The cost of testing will be deducted from any monies due or that may come due the Contractor under the Contract at the rate of $500 per sample. 5-04.3(9)D Mixture Acceptance – Commercial Evaluation If sampled and tested, HMA produced under Commercial Evaluation and having all constituents falling within the tolerance limits of the job mix formula shall be accepted at the unit Contract price with no further evaluation. When one or more constituents fall outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The commercial tolerance limits will be used in the calculation of the CPF and the maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or samples from the street shall be tested to provide a minimum of three sets of results for evaluation. For each lot of HMA mix produced and tested under Commercial Evaluation when the calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. If a constituent is not measured in accordance with these Specifications, its individual pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 5-04.3(10) HMA Compaction Acceptance HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a specified compacted course thickness greater than 0.10-foot, shall be compacted to a specified level of relative density. The specified level of relative density shall be a Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density).

HMA mixture accepted by commercial evaluation and HMA constructed under conditions other than those listed above shall be compacted on the basis of a test point evaluation of the compaction train. The test point evaluation shall be performed in accordance with instructions from the Engineer. The number of passes with an approved compaction train, required to attain the maximum test point density, shall be used on all subsequent paving. HMA for preleveling shall be thoroughly compacted. HMA that is used for preleveling wheel rutting shall be compacted with a pneumatic tire roller unless otherwise approved by the Engineer. Test Results For a sublot that has been tested with a nuclear density gauge that did not meet the minimum of 92 percent of the reference maximum density in a compaction lot with a CPF below 1.00 and thus subject to a price reduction or rejection, the Contractor may request that a core be used for determination of the relative density of the sublot. The relative density of the core will replace the relative density determined by the nuclear density gauge for the sublot and will be used for calculation of the CPF and acceptance of HMA compaction lot. When cores are taken by the Contracting Agency at the request of the Contractor, they shall be requested by noon of the next workday after the test results for the sublot have been provided or made available to the Contractor. Core locations shall be outside of wheel paths and as determined by the Engineer. Traffic control shall be provided by the Contractor as requested by the Engineer. Failure by the Contractor to provide the requested traffic control will result in forfeiture of the request for cores. When the CPF for the lot based on the results of the HMA cores is less than 1.00, the cost for the coring will be deducted from any monies due or that may become due the Contractor under the Contract at the rate of $200 per core and the Contractor shall pay for the cost of the traffic control. 5-04.3(10)A HMA Compaction – General Compaction Requirements Compaction shall take place when the mixture is in the proper condition so that no undue displacement, cracking, or shoving occurs.

Regardless of mix temperature, a roller shall not be operated in a mode that results in checking or cracking of the mat. On bridge decks and on roadway approaches within five feet of a bridge/back of pavement seat, rollers shall not be operated in a vibratory mode, defined as a mode in which the drum vibrates vertically. However, unless otherwise noted on the plans, rollers may be operated in an oscillartory mode, defined as a mode in which the drum vibrates in the horizontal direction only. Refer to contract drawings for HMA Paving Train requirements and restrictions (e.g. equipment spacing, weight limits, etc.). 5-04.3(10)B HMA Compaction – Cyclic Density Low cyclic density areas are defined as spots or streaks in the pavement that are less than 90 percent of the theoretical maximum density. At the Engineer’s discretion, the Engineer may evaluate the HMA pavement for low cyclic density, and when doing so will follow WSDOT SOP 733. A $500 Cyclic Density Price Adjustment will be assessed for any 500- foot section with two or more density readings below 90 percent of the theoretical maximum density. 5-04.3(10)C Vacant 5-04.3(10)D HMA Nonstatistical Compaction 5-04.3(10)D1 HMA Nonstatistical Compaction – Lots and Sublots HMA compaction which is accepted by nonstatistical evaluation will be based on acceptance testing performed by the Contracting Agency dividing the project into compaction lots. A lot is represented by randomly selected samples of the same mix design that will be tested for acceptance. A lot is defined as the total quantity of material or work produced for each Job Mix Formula placed. Only one lot per JMF is expected. A sublot shall be equal to one day’s production or 400 tons, whichever is less except that the final sublot will be a minimum of 200 tons and may be increased to 800 tons. Testing for compaction will be at the rate of 5 tests per sublot per WSDOT T 738. The sublot locations within each density lot will be determined by the Engineer. For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s request after the Engineer is satisfied that material conforming to the Specifications can be produced. HMA mixture accepted by commercial evaluation and HMA constructed under conditions other than those listed above shall be compacted on the basis of a test point evaluation of the compaction train. The test point evaluation shall be performed in accordance with instructions from the Engineer.

The proposed retrofit project is in the Williams Sub-Basin, which includes areas along Burnett Avenue South and Williams Avenue South between the Cedar River and South 2nd Street, including South Tillicum Street and South Tobin Street. Figure 1, Site Vicinity Map, and Figure 2, Site Exploration Plan, show the project location and the approximate Williams Sub-Basin boundary. 1.2 PROJECT UNDERSTANDING We based our project understanding on discussions with Becca Ochiltree of BHC Consultants (BHC) and Amanda Pierce of the City of Renton (the City), as well as 30% drawings dated September 15, 2021. We understand that replacement, rehabilitation, and/or upsizing of the stormwater utilities is being considered to improve outflow water quality and increase system capacity. The City plans to upgrade the existing stormwater infrastructure and retrofit water quality treatment facilities within the Burnett and Williams sub-basin. Based on a review of the City of Renton’s Maps and GIS Data, existing storm water system depths are generally between about 2 to 5 feet below the existing ground surface. The 30% drawings indicate that the upsized storm water lines in Burnett Avenue South will have invert depths of about 4 feet below the ground surface, while the line in South Tobin Street will vary from about 7 to 9 feet deep, and the line in Williams Avenue South will gradually increase from about 5 feet at the south end of the alignment to 12 feet at the north end of the alignment where it ties into the outfall. 1.3 SCOPE OF SERVICES The scope of our geotechnical study consisted of a site reconnaissance and subsurface exploration, limited environmental screening, geotechnical engineering analysis, laboratory testing, and this report. Complete studies to assess regional groundwater behavior and 20212729.001A/SEA21R130976 Page 2 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com environmental hazards that may affect the soil and/or groundwater at the site were beyond our scope of services. The following sections present describe our services performed. 1.3.1 Task 1 – Field Investigation On September 2, 2020, Kleinfelder performed a preliminary site walk and surficial reconnaissance to observe the conditions of the project area and evaluate access for exploration equipment. During the site walk we observed that both Burnett and Williams Avenue are both two lane, one- way streets with on-street parking on the east and west sides of each road. Based on this site walk and discussions with BHC, we decided to advance the boring closest to the outfall in the roadway at the northwest corner of South Tillicum and Williams Avenue, rather than in landscape area, concluded that all planned borings could be readily accessed with a track-mounted drill rig. Due to the presence of a 104-inch diameter King County sanitary sewer and numerous other underground and overhead utilities, borings were not conducted in Burnett Ave South. Prior to drilling, we notified the One-Call Utility locate services as required by the state of Washington so that the member utility companies could mark their facilities. We were notified that Puget Sound Energy (PSE) has a high-pressure gas line in the vicinity of our borings and that an on-site meeting would be required prior to drilling in order to allow PSE to approve our proposed locations. A Kleinfelder representative met on site with representatives from both PSE and the City, who verified that the proposed boring locations would be a sufficient distance from the marked utilities. BHC and the City of Renton coordinated review of our boring locations and plan by the Washington State Department of Ecology (WADOE). Prior to beginning drilling the boring locations were scanned by a private utility locator for conductible utilities and non-conductible underground structures using ground penetrating radar. During these sweeps, a small unmarked or possibly abandoned underground structure was found on South Tobin Street, but was not close enough to impact our borings. We completed the drilling program on February 4, 2021. Borings were advanced by our subcontracted driller, Holocene Drilling, using a Diedrich D-50 rubberized track rig. Three hollow-stem auger (HSA) borings were advanced to a depth of 20 feet below the existing ground surface (bgs) and one to a depth of 30 feet bgs (the boring nearest the Cedar River outfall). Soil sampling consisted of standard penetration test (SPT) samples collected at 2½-foot intervals in the first 10 feet and 5-foot intervals thereafter. At boring KB-1, near the outfall, the first 7½ feet 20212729.001A/SEA21R130976 Page 3 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com was cleared using a truck-mounted vacuum and air knife due to the proximity of the high-pressure gas line. During drilling the soil samples were field screened for organic vapors using a field calibrated photoionization detector (PID). Samples collected during drilling were stored in plastic bags and delivered to Kleinfelder’s laboratory for testing. Appendix A presents the summary boring logs, which provide additional information on the soils encountered and the PID readings. Borings were backfilled with bentonite chips to approximately 4 feet below the top of the existing asphalt road surface. The asphalt surface at each location was then repaired by the driller by filling the remaining 4 feet with concrete, which was mixed with black dye near the surface and troweled to be flush with the roadway. Soil cuttings generated by the borings were placed into drums. Since we did not observe visible indication of contamination or elevated PID readings the drummed cuttings were deemed “clean” and hauled off-site. 1.3.2 Task 2 – Laboratory Testing Laboratory testing was conducted on selected representative samples obtained from the borings to help characterize the site soils and relevant engineering and index properties. Laboratory testing included natural moisture content, grain-size distribution, and Atterberg limits. Tests were conducted in general accordance with appropriate American Society for Testing and Materials (ASTM) Standards and results can be found in Appendix B. 1.3.3 Task 3 – Geotechnical Analyses and Report We prepared this report based on the results of our field and laboratory programs, and the planned improvements. 20212729.001A/SEA21R130976 Page 4 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 2 SITE CONDITIONS ___________________________________________________________________________________ 2.1 SURFACE CONDITIONS The proposed improvements are located near the downtown Renton area, approximately bounded by the Cedar River to the north, South Second Street to the south, Burnett Place South to the west, and Williams Avenue South to the east, as shown on the Vicinity Map, Figure 1. The existing infrastructure along these streets primarily consists of single-family residences, a limited number of single-story commercial buildings, and two multistory apartment complexes. Topography in the area is generally flat and elevations in the vicinity of the improvements range from about Elevation 36 to 40 feet above mean sea level (WGS84), except for the banks of the Cedar River, which slope down to the river at about Elevation 25 feet. During our site visits we observed that the banks of the Cedar River appear to have been lined with rip rap rock and geotextile fabric. The existing outfall is located on the south bank of the Cedar River, to the west of the Williams Avenue Bridge. We were unable to be observe the outfall during our site walks due to it being obscured by the rip rap and vegetation. 2.2 GEOLOGIC SETTING The project area is located in the central portion of the Puget Lowlands, an elongated, north-south depression situated between the Olympic Mountains and the Cascade Range. Repeated glacial advances (glacial events) into this region strongly influenced present-day topography, geology, and groundwater conditions in the project area. Puget Lowlands consist of a variety of soils from glacially overridden lacustrine deposits to outwash and glacial drift deposits. Fine grained and course grained alluvium and flood plain deposits, volcanic mudflows, and landslide materials are all present in the general project vicinity. Based on the Washington Department of Natural Resources Interactive Geologic Map (1:250,000 scale), surficial soils at the site are anticipated to consist of fill. Fill may consist of well compacted material free of organics (engineered fills) or poorly compacted materials containing organics, timbers, debris, and other unknown objects (undocumented fills). The anticipated thickness of the fill layer varies but may be on the order of 10 feet where present. Mapping at the 1:500,000 scale indicates that the project area is underlain by a variety of native soils ranging from alluvium to 20212729.001A/SEA21R130976 Page 5 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com till-like glacial drifts. The alluvium materials, interbedded silty sands and sandy silts with organic silts and peat, likely range from 50 to 80 feet thick. Below this, soils are anticipated to transition into glacial drift deposits, which consist of till-like dense sandy gravel and gravelly sand, with cobbles and boulders strewn within. The geology for portions of the site is impacted by the diversion of the Cedar River in 1912. In 1911 there was a major flood along the lower Cedar River that prompted the city of Renton to divert the river directly into Lake Washington, which created the current channel location. Our Site and Exploration Plan, Figure 2, depicts the approximate former channel the Cedar River, which underlies the northeast portion of the project area. The borings were advanced within the old Cedar River channel and boring KB-1, located near the outfall, encountered buried timber starting at approximately 25 feet bgs. Based on a review of available data for the downtown Renton area, groundwater ranges from as shallow as 4 feet bgs to as deep as 20 feet bgs. The depth to groundwater is expected to vary with seasonal changes in rainfall and surface runoff, impacts of local development, and the level of the Cedar River. 2.3 EXISTING GEOTECHNICAL DATA Between September of 2017 and March of 2020 Kleinfelder performed a variety of tasks as the environmental and geotechnical engineering consultant for the City of Renton’s Downtown Utility Improvement Plan (DUIP). These tasks included a review four prior geotechnical reports authored by others for developments within the downtown Renton area; a desktop study the of existing geologic information; three phases of field explorations to evaluate soil and groundwater conditions within the project area; a Phase I environmental desktop study; and a Phase II environmental field exploration to further evaluate potentially impacted soils within the project area. Two prior Kleinfelder borings for the DUIP study, KB-04 and MW-5, are located at the southeast and southwest corners of the Williams sub-basin and are referenced for this report. Our report for the DUIP, and the other prior development reports, describe similar soil units and conditions to those encountered in our borings for this project. These reports generally describe about 10 feet of fill comprised of soft silts and loose sands, but the fill depths ranged from as shallow as 3 feet and to as deep as 20 feet below the existing ground surface. Below the fill, borings encountered alluvium, which included loose to medium dense silty sands, gravels, and possible cobbles and boulders. The alluvium deposits generally became dense at around 20 to 20212729.001A/SEA21R130976 Page 6 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 30 feet bgs and extended to the boring termination depths of up to 50 feet bgs. Some borings within the vicinity of Rainier Avenue South and South Second Street also encountered sandstone or siltstone bedrock at approximately 20 to 30 feet bgs. Groundwater monitoring wells installed along South 2nd Street and South 3rd Street monitored from April 2019 through January 2020 indicated groundwater levels between about 10 and 13 feet below the existing ground surface. Groundwater levels were generally slightly shallower, about 7 feet bgs, near Rainier Avenue South and deepened to about 15 feet closer to the Cedar River. In MW-5, located at the southwest corner of the Burnett and Williams project boundary, observed groundwater levels ranged from about 14 to 17 feet bgs. Reported pavement sections varied from asphalt with an aggregate base course to asphalt over concrete with an aggregate base course, and in a few borings brick pavement was encountered beneath the asphalt or aggregate base course. Asphalt thicknesses were generally about 4 to 6 inches, but ranged from 2½ to 12 inches. Concrete thicknesses were generally about 4 to 8 inches. Pavement sections with brick were only encountered along South 3rd Street. The prior reports noted the presence of potentially caving soils and shallow groundwater seepage, as well as the presence of potentially liquefiable soils below the water table. One report noted that an existing building located southeast of the Burnett and Williams project boundary experienced severe post-construction settlement and cautions to avoid strong ground vibrations during construction and demolition. This report also recommended settlement monitoring be performed on the nearby existing building during construction and that an existing-condition and post-construction survey be performed. These recommendations are important to consider for the Burnett and Williams Water Quality Upgrades project, and emphasize the importance of considering an existing-condition survey prior to construction and performing settlement monitoring, depending on the nature and location of planned construction activities relative to existing infrastructure. 2.4 SUBSURFACE CONDITIONS 2.4.1 Soils Based on our review of existing geotechnical data and the conditions encountered in our borings, soils along the alignment are somewhat variable. Historical events such as the diversion of the Cedar River, lowering the level of Lake Washington, and land modification associated with 20212729.001A/SEA21R130976 Page 7 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com development have had a significant impact on this site’s topography and surface geology. We have characterized soils encountered in the borings in generalized units for the purpose of discussion, which are described below in the order encountered. The summary boring logs in Appendix A and Appendix C present more detail relative to the subsurface conditions observed at specific locations. • Fill: Fill was encountered just below the pavement sections and generally ranged from about 7½ to 15 feet thick. Borings KB-1 through KB-3, located in Williams Avenue South and South Tobin Street, encountered a mix of silts and sands with varying amounts gravel, likely placed to fill the historical Cedar River channel. Borings KB-4, in the alley south of Williams Avenue South, encountered gravel with varying amounts of silt and sand, likely placed more recently as backfill for the below grade portion of the nearby apartments. Moisture contents ranged from about 4 to 7 percent within the gravel fill soils and from about 8 to 33 percent in the silty fill soils. SPT N-Values within the silty fill soils generally ranged from 2 to 4 blows per foot, which correlates to a consistency of loose to medium stiff. SPT N-Values within the granular fill soils found in KB-4 ranged from 7 blows per foot near the surface to 38 blows per foot above the alluvium, which correlates to a loose to dense consistency. • Alluvium: These soils were encountered below the fill in each of our borings and extended to their termination depths. They were comprised of a mix of fine to coarse sands and gravels with varying silt contents. Moisture contents ranged from about 5 to 28 percent but were generally about 6 to 10 percent. SPT N-Values within the alluvium were between 11 to 36 blows per foot, which correlates to medium dense to dense sands and gravels. The granular soils in this unit are considered water bearing. The higher moisture contents observed in some samples from KB-1 are likely reflective of some of the organic deposits mixed in with the alluvium as described below. • Buried Timber/Logs: Boring KB-1 encountered pieces of buried wood (interpreted as timber or logs) at depths of approximately 25 and 30 feet bgs. KB-1 is located within the former Cedar River channel and this material is likely associated with deposits from before the river was diverted. Our review of prior reports noted similar materials at depths between 20 to 30 feet bgs in other borings, and the area is known for potential buried logs. If the planned project changes such that deeper utilities or an outfall are included, or temporary shoring is planned to penetrate below 20 feet, construction means and methods should account for potential obstructions due to timber and logs. In addition, if utilities or 20212729.001A/SEA21R130976 Page 8 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com structures need to be founded below about 15 feet bgs, Kleinfelder should be contacted to discuss options to mitigate potential settlement associated with the organic material. 2.4.2 Pavements Borings in the roadways encountered asphaltic concrete pavement sections approximately 3 to 4 inches thick with approximately 4 to 6 inches of base course. At boring KB-4, located in the alleyway between Burnett Ave and Williams Ave, the asphalt pavement was approximately 2 inches thick with approximately 6 inches of base course comprised of what appeared to be recycled concrete. 2.4.3 Groundwater Groundwater levels observed during drilling were generally about 15 feet bgs. Groundwater monitoring was performed at MW-5, installed previously as part of the DUIP project, approximately once a month from April 2019 through January 2020. Groundwater levels within this monitoring well ranged from about 14.3 feet bgs in January of 2020 to 17.8 feet bgs in August of 2019. Perched groundwater conditions may develop seasonally, particularly overlying fine-grained soils or in sand seams and may be encountered at shallower depths than those encountered in our borings. The groundwater conditions reported above are for the specific dates and locations indicated and, therefore, may not necessarily be indicative of other times and/or locations. It is anticipated that ground water conditions will vary depending on the season, rate and duration of recent precipitation, local subsurface conditions, the level of the Cedar River, and other factors. A detailed investigation of regional groundwater conditions was outside the scope of our study. 20212729.001A/SEA21R130976 Page 9 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 3 GEOLOGIC HAZARDS ___________________________________________________________________________________ The site is located in moderate to high liquefaction susceptibility hazard area per King County Flood Control District Map 11-5 Liquefaction Susceptibility. Soil liquefaction is a condition where saturated, granular soils undergo a substantial loss of strength due to pore pressure increase from cyclic stress induced by earthquakes. In the process, the soil may undergo horizontal displacements (lateral spreading) and vertical settlement. Utility damage caused by liquefaction and lateral spreading include, but is not limited to, pulled / broken connections, pipe breakage, loss of gravity flow due to vertical displacement, and uplift or floatation, particularly in manhole structures that extend below the groundwater table. Areas along the project alignment are relatively flat and are generally not considered susceptible to landslide or seismically induced slope failures. 20212729.001A/SEA21R130976 Page 10 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 4 GEOTECHNICAL CONCLUSIONS AND RECOMMENDATIONS ___________________________________________________________________________________ 4.1 GENERAL General conclusions and recommendations developed based on the results of our exploration and analysis are summarized below and detailed in the following sections. • The contractor will be responsible for selecting appropriate means and methods to accomplish the utility installation. It is important that means and methods consider many factors, including but not limited to, the factors discussed in this report, and summarized below: o Variable soil conditions including soft fine-grained soils, loose granular soils, dense granular soils, and buried timber; and, o The need to dewater or control groundwater for deeper utilities while also limiting groundwater drawdown and preventing settlement of existing utilities and structures. • Excavations for utility installation will be made adjacent to existing utilities, structures or pavements that are to remain and require protection. Site soils, particularly the weaker (soft/loose) soils, and soils below the groundwater table, are highly susceptible to sloughing, raveling, and flowing. Positive support of soils in the trench walls will be required in many areas in order to limit disturbance beyond the trench. • Excavations located away from existing utilities, structures or pavements that will remain in place can be sloped when made above the ground water table, but this will require a larger excavation volume and increased pavement restoration areas, and may not accommodate traffic lanes that must remain open. • Excessive vibrations may cause ground settlement, and corresponding settlement and damage to nearby utilities and buildings if proper precautions are not taken. Use of vibratory methods to install shoring should be evaluated carefully and appropriate pre-condition surveys, vibration monitoring, and settlement monitoring should be performed. 20212729.001A/SEA21R130976 Page 11 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com • The contractor will need to carefully evaluate shoring means and methods for accomplishing the work. We anticipate that a combination of structural and non-structural shoring methods may be required. Structural shoring, as defined in Section 2-09.3(3) D of the WSDOT Standard Specifications, is a shoring system that is installed prior to excavation and provides lateral support of soils to limit lateral movement. Non-structural shoring, which is installed after excavation, may provide worker protection, but typically allows some soil movement and does not provide the same level of protection for existing infrastructure. • We recommend settlement monitoring points and a pre-construction survey of buildings be discussed with the project team as it may be appropriate to establish them along the existing utilities and structures. A suggested rule of thumb would be to monitor and survey buildings where the distance from the edge of the excavation to the building is less than the depth of the excavation. • We understand current WSDOT/APWA Standard Specifications will be used for this project along with City of Renton Standard Details. 4.2 EXCAVATIONS 4.2.1 General Given the anticipated depth of the utilities and treatment facilities (about 5 to 12 feet bgs) we anticipate that shoring requirements for this project will likely be non-structural as defined in Section 2-09.3(3) D of the WSDOT Standard Specifications and that sumps and pumps will be sufficient to deal with nuisance groundwater seepage into excavations. If excavations extend beyond about 15 feet below the existing ground surface the contractor will need to carefully evaluate the combination of shoring (structural vs non-structural) and dewatering methods for accomplishing the work. Considerations should focus on, but not be limited to, worker safety and protection of the existing buildings and utilities. Structural shoring provides support prior to excavation to limit lateral movement and can include a variety of methods, some of which are discussed in in Section 4.2.5.1. Non-structural shoring could include trench boxes or other systems, which are installed after the excavation is completed. These systems may provide worker protection, but typically allow soil movement, do not provide the same level of protection for existing infrastructure, and will be difficult to install in soils that do not stand unsupported. Some of these methods are discussed in Section 4.2.5.2. 20212729.001A/SEA21R130976 Page 12 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 4.2.2 Excavation Conditions and Obstructions We anticipate that excavation of the on-site fill and alluvial deposits can be performed with conventional earthmoving equipment. Buried logs or timber, construction debris, concrete slabs or utilidors may be encountered during excavation activities. While not anticipated, if old piles or abandoned concrete utility ducts are encountered, they should be cut off at least 3 feet below trench subgrade level. The contractor should anticipate the excavation, removal, and replacement of these materials with compacted structural fill as recommended in Sections 4.5.3 and 4.5.4. Due to the numerous utilities existing on site, potholing should be performed to identify existing utility locations prior to beginning excavations. Hand excavation and/or use of a vacuum truck may be advantageous when excavating around some utilities. 4.2.3 Settlement Monitoring While not currently anticipated, if excavations for utilities will be performed close to existing buildings or groundwater draw down due to construction dewatering will exceed about 5 feet, consideration should be given to settlement monitoring. As a general rule of thumb, if utility excavations will be within a horizontal distance from a structure equal to or less than the depth of the excavation, consideration should be given to monitoring the structure. Kleinfelder should be contacted to review conditions on a case-by-base basis as the project plans are developed. 4.2.4 Temporary Slopes All excavations and slopes must comply with applicable local, state, and federal safety regulations including the current OSHA Excavation and Trench Safety Standards and WISHA Safety Standards for Construction Work. Construction site safety is the sole responsibility of the Contractor, who shall also be solely responsible for the means, methods, and sequencing of construction operations. Most of the on-site soils should be considered as Type C soils, which should be inclined no steeper than 1½H:1V. However, some of the site soils are soft / loose and may require even flatter sloping to be stable and safe. The above recommendations are for excavations made above the groundwater table. Excavations made below the groundwater table should be shored. Due to proximity to utilities and the need to maintain some traffic lanes in roadways, sloping of excavations may be impractical. 20212729.001A/SEA21R130976 Page 13 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com Temporary slopes should be protected from the elements by covering with plastic sheeting or similar means. Sheeting sections should overlap by at least 12 inches and be tightly secured with sandbags, tires, staking, or other means to prevent wind from exposing the soils under the sheeting. Heavy equipment, building materials, excavated soil, and vehicular traffic should not be allowed near the top of any sloped temporary excavation. 4.2.5 Temporary Shoring Where the stability of adjoining buildings, walls, utilities, or other structures is endangered by excavation operations, support systems such as shoring, bracing, or underpinning may be required to provide structural stability and to protect personnel working within the excavation. If earth retention, structural-shoring, bracing, or underpinning are used for the project they should be designed by a professional engineer registered in the State of Washington. Temporary shoring should be utilized where sloping excavations is not practical. Excavations that are adjacent to existing utilities, structures or pavements that are to remain should be shored to prevent ground loss or movement and potential damage to the existing utilities or structures. 4.2.5.1 Structural Shoring Structural shoring includes systems that are installed and provide soil support prior to excavation per Section 2-09.3(3) D of the WSDOT Standard Specifications. Some examples of structural shoring systems include driven cantilever sheet piles; sheet piles with tiebacks, wale rings or struts; cantilever soldier piles with lagging and soldier piles with lagging and tiebacks. Structural shoring may be required due to the proximity of existing utilities or structures, due to weak soils that cave or slough rapidly, to limit areas of disturbance, or other factors. Based on the currently proposed improvements and relatively limited depths, structural shoring may only be required at the deeper structures, if at all; selection of the shoring system is ultimately a contractor means and methods decision. The following sections present a short discussion of two potential structural shoring options and are not intended to limit the contractor’s available means and methods for structural shoring. 20212729.001A/SEA21R130976 Page 14 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com Sheet Piles Due to potential for vibration induced settlement, construction of a sheet pile shoring system using impact and conventional vibratory hammers are not recommended. However, sheet piles installed using a variable eccentric moment hammer could be considered. A vibratory hammer with a variable eccentric moment can be started and stopped with much lower vibration levels than with conventional hammers, which can allow sheet piles to be installed near settlement sensitive structures such as buildings and nearby utilities. The sheet pile shoring system could be either cantilever or braced depending on the required excavation height and groundwater levels. One potential issue with a sheet pile shoring system would be the relatively deep embedment required to cut off groundwater flow to meet base heave stability requirements. Dense gravels encountered at depth may also prevent sheets from being driven to the design tip elevation or cause them to be driven out of interlock thereby allowing seepage and soil movement into the excavation. Sheet pile embedment requirements for groundwater cutoff could be reduced by installing a jet grout cut-off barrier below the minimum required tip for structural considerations or by using a dewatering / depressurization system. Soldier Piles and Lagging Soldier piles can be installed in conventional drilled holes, but temporary casing and use of a slurry and/or water surcharge to control bottom heave should be anticipated for installation especially below the groundwater table. For solider piles that are vibrated into place without a drilled hole, vibrations should be controlled in a similar manner as discussed above by use of a variable eccentric moment hammer. Timber or steel sheets can be used for lagging, but the system should not be considered watertight and there will be significant risk of running / flowing sands entering the excavation unless dewatering is performed prior to excavation. Grouting or other ground improvement methods could be utilized prior to excavation to control groundwater flows and improve soil stability. Base heave stability requirements discussed above may also be a controlling factor in design of soldier pile shoring. 20212729.001A/SEA21R130976 Page 15 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 4.2.5.2 Non-Structural Shoring Non-structural shoring includes systems that don’t meet the definition of structural shoring and can be divided into two general categories: shielding and shoring/bracing. Examples of shielding include trench boxes and sliding trench shields. Shields are intended primarily to protect workers from cave-ins and do not provide “positive” support of trench sidewalls. As a result, a significant amount of sloughing can occur outside of the trench box, resulting in increased surface disturbance. Examples of shoring/bracing include jacked or braced shores, and soldier pile, sheet pile, or similar shoring walls installed in front of a pre-excavated slope. Jacked or braced shores can utilize wood or aluminum sheeting and be supported with hydraulic, pneumatic, or screw jacks inserted against the sheeting and expanded to provide “positive” support of trench sidewalls. 4.3 DEMOLITION Demolition will include removal of existing asphalt pavement, potentially concrete sidewalks, curbs, and aboveground or underground utilities. During demolition activities, all excavations for demolished utility vaults, utility lines, or other purposes should be backfilled with compacted structural fill, as recommended herein. Existing pavement sections will need to be removed at the start of the planned utility excavations. While these sections were not encountered in borings for this study, the contractor should be prepared to remove a variety of pavement materials including layers / combinations of Hot Mix Asphalt pavement, Portland Cement Concrete pavement, and brick. Pavement sections we encountered generally consisted of 2 to 4 inches of asphalt concrete over aggregate base. Other borings for prior studies in the downtown Renton area encountered asphalt overlying concrete sections up to 8 inches thick and asphalt overlying brick pavement. Neat saw cuts should be required for the margins of all areas of pavement removal, and the extent of pavement removal should account for the planned construction activity, as well as the location of saw cut joints with respect to traffic lanes and wheel paths as outlined in City Standards. The allowed locations for pavement joints may be revised if a mill and overlay will be used to reduce cold joints and avoid locating surface joints in wheel paths. 20212729.001A/SEA21R130976 Page 16 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com Excavations should be supported such that sloughing or undermining of soils supporting pavements or other infrastructure to remain does not occur. If undermining, settlement, or other loss of support occurs it will be necessary to remove additional pavement. This should be done at no cost to the City and with revised saw cut joints in locations determined by a representative of the City. During the course of our field exploration we encountered a number of utilities in the vicinity of our borings, some of which were not marked by our public located request but were instead identified by our private locating subcontractor and may be abandoned. Prior reports also identified unmarked utilities encountered in potholes at 3 to 4 feet bgs, which included a white 3-inch diameter PVC pipe and a rectangular concrete corridor (potential utility duct) on South 2nd Street. Utilities that are to be replaced and are within the excavation area should be removed from the excavation area prior to the installation of new utilities. If required, utility duct demolition and cut off should be accomplished in a manner that prevents damage to the remaining structures and the ends should be sealed with concrete to prevent soil and water from entering the duct. If the duct must be breached to accommodate installation of other utilities, the breach should be sealed with a concrete mass poured into the duct or reinforced concrete slabs/walls. Concrete seals should be designed for a vertical earth pressure equivalent to that generated by a fluid with a unit weight of 125 pounds per cubic foot (pcf) and a lateral earth pressure of 65 pcf. Alternatively, ducts could be backfilled with Controlled Density Fill (CDF) also known as Controlled Low Strength Material (CLSM) provided the contractor is able to deliver the material in a manner that completely fills voids in the duct. CDF should conform to the requirements of Section 2-09.3(1)E Backfilling of the WSDOT Standard Specifications. 4.4 PAVEMENTS 4.4.1 Pavement Repairs / Restoration We understand the City has determined that pavements impacted by utility work will be repaired in accordance with the City of Renton 2018 Trench Restoration and Street Overlay Requirements. In our opinion these are appropriate requirements for the project. Saw cuts and/or grinding should extend a minimum of 1 foot beyond the trench edges and overlays in grinding areas should be a minimum of 2 inches thick. Other factors such as patch orientation, minimum patch widths, and proximity to travel lanes must also be accounted for in determining final repair extents in accordance with City requirements. 20212729.001A/SEA21R130976 Page 17 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com In addition to accounting for the edges of trenches, final patching requirements should encompass and extend 1 foot beyond any additional areas affected by soil movement, settlement, or pavement damage. Additional pavement repairs that are required due to soil movement should be performed at no cost to the City. At the discretion of the engineer, a full lane-width or full street-width overlay may be required. We do not recommend performing a grind and overlay in areas where the existing asphalt is less than 4 inches thick as it becomes difficult to avoid damaging the remaining pavement with construction traffic and variations in grade and pavement thickness can inadvertently result in the milling process damaging or completely removing the pavement section. 4.4.2 New Pavement Sections We understand City of Renton standard sections will be used. Based on our review of the provided standard pavement details, the planned replacement section is a minimum of 6 inches of ½” PG 64-22 Hot Mix Asphalt overlying a minimum of 6 inches of crushed surfacing. This seems reasonable relative to the thicknesses of the existing pavement sections, which generally appear to be performing adequately. Given the variability of the existing pavement section thicknesses and materials, using a standard section for replacement in areas to be removed is recommended over requiring the contractor to match the existing sections encountered as construction progresses. 4.4.3 Pavement and Aggregate Materials and Workmanship Hot Mix Asphalt should conform to requirements of Section 5-04 of the WSDOT Standard Specifications. Aggregate base should conform to Section 9-03.9(3) Crushed Surfacing of the WSDOT Standard Specifications and be compacted to at least 95 percent of the Modified Proctor maximum dry density as determined by ASTM D1557 / AASHTO T180. 4.5 EARTHWORK 4.5.1 Trench and Manhole Subgrades Excavation for trenches and manholes should be done in a manner to minimize disturbance of subgrade soils that will remain in place. Where subgrade soils for manholes consist of 20212729.001A/SEA21R130976 Page 18 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com predominantly granular material, it may be appropriate to compact soils with a plate compactor, jumping jack, or tamping of the excavator bucket to firm up subgrades. Disturbance of soils with high fines contents may require over-excavation and replacement with material conforming to Section 9-03.9(3) Crushed Surfacing of the WSDOT Standards, or other approved material. Utility trenches, particularly in areas below the static water table, may encounter soft subgrades. In many areas pipe bedding will be adequate to stabilize subgrade. Where excessively soft trench subgrade soils are encountered, a geotextile fabric conforming to the requirements of Section 9-33.2(1) Construction Geotextile for Soil Stabilization of the WSDOT Standard should be placed over the subgrade and a 1-foot thick layer 2-4 inch quarry spalls or material conforming to Section 9-03.9(3) Crushed Surfacing of the WSDOT Standards should be placed over the geotextile. In areas with very soft and weak subgrades it may be appropriate to mix the contents of a bulk sack of dry cement into the subgrade and allow it to begin to cure before placing geotextile fabric and rock. Edges of the fabric should overlap a minimum of 18 inches and the fabric should be placed flat over the subgrade with no excessive wrinkles or folds. The contractor should be prepared to utilize geotextile fabric at the direction of the geotechnical engineer. We recommend the contract documents include unit prices for furnishing and installation of geotextile stabilization fabric. 4.5.2 Weather Considerations During wet weather and in areas where the exposed subgrade may consist of moisture-sensitive soils (soils containing approximately more than 10 percent fines based on the fraction passing the ¾-inch sieve), the contractor should take measures to protect subgrade excavations once the geotechnical engineer has approved them. These measures could include, but are not limited to, placing a layer of crushed surfacing over the subgrade and/or keeping construction traffic off the subgrade. If additional over-excavation and material replacement is required because the subgrade was not protected, the cost of such additional work should be borne by the contractor. After a rainfall, construction equipment travel on the exposed site subgrade should be minimized until the soils have been allowed to dry sufficiently. Otherwise, traffic activity on the wetted subgrade will degrade the exposed materials and result in additional excavation of the disturbed materials. 20212729.001A/SEA21R130976 Page 19 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 4.5.3 Structural Fill Materials All fill placed below pavements, sidewalks, or structures such as catch basins should be considered structural fill. The on-site fill and native soils that will be excavated from utility trenches will generally be unsuitable for re-use as structural fill because they contain a high fines content and will be over their optimum water content and not readily compactable. In addition, the project site may not have room for temporary stockpiling of trench materials near the work areas. Therefore, we recommend the contract documents include a provision for import of structural fill and export of unsuitable soils with unit pricing. The suitability of on-site soils for re-use can be evaluated on a case-by-case basis during utility installation by a representative of Kleinfelder, if desired. Structural fill materials and bedding should conform to WSDOT/APWA standards, as well as City of Renton details. Pipe zone backfill placed within 6 inches of pipes should conform to the requirements of Section 9-03.12(3) Gravel Backfill for Pipe Zone Bedding of the WSDOT Standards, or manufacturer requirements. Imported structural fill should consist of material conforming to the requirements of Section 9-03.14(1) Gravel Borrow of the WSDOT Standards. Material placed within the pavement section should conform to the corresponding pavement section requirements. Materials should be imported to the site and protected or maintained so that they are not more than 3 percent over their optimum moisture content at the time of placement and compaction. The contractor should provide submittals as required by the contract documents. Once approved for use, the contractor should submit samples of import materials to the geotechnical engineer for evaluation and testing prior to use. The samples should be submitted at least 4 days prior to their use and sufficiently in advance of the work to allow the contractor to identify alternative sources if the material proves unsatisfactory. In some instances where multiple utilities cross in a small area and backfill cannot be readily worked and compacted around the utilities, it may be advantageous to backfill with CDF. CDF should conform to the requirements of Section 2-09.3(1)E Backfilling of the WSDOT Standard Specifications and we recommend the contract documents include a unit price for CDF backfill. Use of CDF should only be approved on a case-by-case basis by the engineer. 20212729.001A/SEA21R130976 Page 20 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 4.5.4 Structural Fill Placement and Compaction We understand that the WSDOT/APWA Standard Specifications will be used for this project. We recommend that laboratory compaction testing be performed based on the modified Proctor test method (ASTM D1557 / AASHTO T180) as opposed to the standard Proctor test method (ASTM D698 / AASHTO T99). The higher compaction standard of the modified Proctor is appropriate considering that extensive trenching will be performed through existing road sections and pavements that will not be totally reconstructed. Using the higher density standard will reduce the potential for differential settlement. Prior to placement and compaction, structural fill should be moisture conditioned to within 3 percent of the optimum moisture content. Fill should be placed in loose lifts with a maximum thickness of 8 inches and should be compacted to the following minimum relative compaction based on the modified Proctor test method (ASTM D1557): • Catch Basin/Structure/Manhole Foundations: 95 Percent • Pavement/Sidewalk Subgrades: 95 Percent • Trench Backfill: 95 Percent • Pipe Zone Bedding: 90 Percent (within 6 inches of pipe) In addition to meeting the above density requirements, all fill should be firm and unyielding when loaded. We recommend all structural fill compaction be observed and tested by a representative of the geotechnical engineer. 4.5.5 Construction Dewatering Based on the anticipated pipeline and treatment facility depths, dewatering is not anticipated with the exception of the potential outfall replacement, if included in the project. However, due to the potential for isolated areas of perched water and minor seepage, the contractor should be prepared to address nuisance water by use of sumps and pumps. Where encountered, the groundwater level should be maintained two feet below the excavation bottom until at least two feet of backfill has been placed, and the groundwater should not be allowed to rise any higher than two feet below the level of excavation backfill during the backfill operation. Excessive lowering of the groundwater table during construction, or on a long-term basis, can induce settlement of the observed soils within the project area and could result in damage to 20212729.001A/SEA21R130976 Page 21 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com structures and utilities in the area if not properly managed. In general, we do not recommend lowering groundwater by more than 10 feet of drawdown. However, it is the contractor’s responsibility to evaluate appropriate dewatering methods and drawdown levels along the alignment to prevent damaging settlements and/or migration of groundwater contaminants. 4.6 ENVIRONMENTAL FIELD SCREENING All soil samples were field screened for organic vapors using a field calibrated photoionization detector (PID) and monitored for evidence of petroleum staining and/or odors. No indications of contamination or elevated PID readings were noted in any of the borings, therefore no soil samples were submitted for laboratory analysis of petroleum hydrocarbons or volatile organic compounds. The drummed soil cuttings were deemed “clean” and disposed of off-site as clean material. 20212729.001A/SEA21R130976 Page 22 of 24 September 27, 2021 © 2021 Kleinfelder www.kleinfelder.com 5 LIMITATIONS ___________________________________________________________________________________ This geotechnical study has been prepared for the exclusive use of BHC Consultants and the City of Renton for specific application to the proposed Burnett Ave South and Williams Ave South Water Quality Improvement Project. The findings, conclusions and recommendations presented in this report were prepared in accordance with generally accepted geotechnical engineering practice. No other warranty, express or implied, is made. The scope of services was limited to a background data review and the field exploration described in Section 1.

ECY 070-560 (rev. 06/21) 1 IDP Form Site Name(s): : Location County:Project Lead/Organization: •An accumulation of shell, burned rocks, or other food related materials. •Bones, intact or in small pieces. •An area of charcoal or very dark stained soil with artifacts. •Stone tools or waste flakes (for example, an arrowhead or stone chips). •Modified or stripped trees, often cedar or aspen, or other modified natural features, such as rock drawings. •Agricultural or logging materials that appear older than 50 years. These could include equipment, fencing, canals, spillways, chutes, derelict sawmills, tools, and many other items. •Clusters of tin cans or bottles, or other debris that appear older than 50 years. •Old munitions casings. Always assume these are live and never touch or move. •Buried railroad tracks, decking, foundations, or other industrial materials. •Remnants of homesteading. These could include bricks, nails, household items, toys, food containers, and other items associated with homes or farming sites. If this Inadvertent Discovery Plan (IDP) is for multiple (batched) projects, ensure the location information covers all project areas. 1.INTRODUCTION The IDP outlines procedures to perform in the event of a discovery of archaeological materials or human remains, in accordance with applicable state and federal laws. An IDP is required, as part of Agency Terms and Conditions for all grants and loans, for any project that creates disturbance above or below the ground. An IDP is not a substitute for a formal cultural resource review (Executive 21-02 or Section 106). Once completed, the IDP should always be kept at the project site during all project activities. All staff, contractors, and volunteers should be familiar with its contents and know where to find it. 2.CULTURAL RESOURCE DISCOVERIES A cultural resource discovery could be prehistoric or historic. Examples include (see images for further examples): The above list does not cover every possible cultural resource. When in doubt, assume the material is a cultural resource. 3. ON-SITE RESPONSIBILITIES If any employee, contractor, or subcontractor believes that they have uncovered cultural resources or human remains at any point in the project, take the following steps to Stop-Protect-Notify. If you suspect that the discovery includes human remains, also follow Sections 5 and 6. STEP A: Stop Work. All work must stop immediately in the vicinity of the discovery. STEP B: Protect the Discovery. Leave the discovery and the surrounding area untouched and create a clear, identifiable, and wide boundary (30 feet or larger) with temporary fencing, flagging, stakes, or other clear markings. Provide protection and ensure integrity of the discovery until cleared by the Department of Archaeological and Historical Preservation (DAHP) or a licensed, professional archaeologist. Do not permit vehicles, equipment, or unauthorized personnel to traverse the discovery site. Do not allow work to resume within the boundary until the requirements of this IDP are met. STEP C: Notify Project Archaeologist (if applicable). If the project has an archaeologist, notify that person. If there is a monitoring plan in place, the archaeologist will follow the outlined procedure. STEP D: Notify Project and Washington Department of Ecology (Ecology) contacts. Project Lead Contacts Primary Contact Alternate Contact Name: Name: Organization: Organization: Phone: Phone: Email: Email: Ecology Contacts (completed by Ecology Project Manager) Ecology Project Manager Alternate or Cultural Resource Contact Name: Name: Program: Program: Phone: Phone: Email: Email: ECY 070-560 (rev. 06/21) 2 IDP Form STEP E: Ecology will notify DAHP. Once notified, the Ecology Cultural Resource Contact or the Ecology Project Manager will contact DAHP to report and confirm the discovery. To avoid delay, the Project Lead/Organization will contact DAHP if they are not able to reach Ecology. DAHP will provide the steps to assist with identification. DAHP, Ecology, and Tribal representatives may coordinate a site visit following any necessary safety protocols. DAHP may also inform the Project Lead/Organization and Ecology of additional steps to further protect the site. Do not continue work until DAHP has issued an approval for work to proceed in the area of, or near, the discovery.

SPECIAL PROCEDURES FOR THE DISCOVERY OF HUMAN SKELETAL MATERIAL Any human skeletal remains, regardless of antiquity or ethnic origin, will at all times be treated with dignity and respect. Follow the steps under Stop-Protect-Notify. For specific instructions on how to handle a human remains discovery, see: RCW 68.50.645: Skeletal human remains—Duty to notify—Ground disturbing activities—Coroner determination— Definitions. Suggestion: If you are unsure whether the discovery is human bone or not, contact Guy Tasa with DAHP, for identification and next steps. Do not pick up the discovery. Guy Tasa, PhD State Physical Anthropologist Guy.Tasa@dahp.wa.gov (360) 790-1633 (Cell/Office) For discoveries that are confirmed or suspected human remains, follow these steps: 1. Notify law enforcement and the Medical Examiner/Coroner using the contacts below. Do not call 911 unless it is the only number available to you. Enter contact information below (required): • Local Medical Examiner or Coroner name and phone: • Local Law Enforcement main name and phone: • Local Non-Emergency phone number (911 if without a non-emergency number): 2. The Medical Examiner/Coroner (with assistance of law enforcement personnel) will determine if the remains are human or if the discovery site constitutes a crime scene and will notify DAHP. 3. DO NOT speak with the media, allow photography or disturbance of the remains, or release any information about the discovery on social media. 4. If the remains are determined to be non-forensic, Cover the remains with a tarp or other materials (not soil or rocks) for temporary protection and to shield them from being photographed by others or disturbed. ECY 070-560 (rev. 06/21) 4 IDP Form ECY 070-560 (rev. 06/21) 5 IDP Form Further activities: •Per RCW 27.44.055, RCW 68.50, and RCW 68.60, DAHP will have jurisdiction over non-forensic human remains. Ecology staff will participate in consultation. Organizations may also participate in consultation. •Documentation of human skeletal remains and funerary objects will be agreed upon through the consultation process described in RCW 27.44.055, RCW 68.50, and RCW 68.60. •When consultation and documentation activities are complete, work in the discovery area may resume as described in Section 8. If the project occurs on federal lands (such as a national forest or park or a military reservation) the provisions of the Native American Graves Protection and Repatriation Act of 1990 (NAGPRA) apply and the responsible federal agency will follow its provisions. Note that state highways that cross federal lands are on an easement and are not owned by the state. If the project occurs on non-federal lands, the Project Lead/Organization will comply with applicable state and federal laws, and the above protocol. 7.DOCUMENTATION OF ARCHAEOLOGICAL MATERIALS Archaeological resources discovered during construction are protected by state law RCW 27.53 and assumed eligible for inclusion in the National Register of Historic Places under Criterion D until a formal Determination of Eligibility is made. The Project Lead/Organization must ensure that proper documentation and field assessment are made of all discovered cultural resources in cooperation with all parties: the federal agencies (if any), DAHP, Ecology, affected tribes, and the archaeologist. The archaeologist will record all prehistoric and historic cultural material discovered during project construction on a standard DAHP archaeological site or isolate inventory form. They will photograph site overviews, features, and artifacts and prepare stratigraphic profiles and soil/sediment descriptions for minimal subsurface exposures. They will document discovery locations on scaled site plans and site location maps. Cultural features, horizons, and artifacts detected in buried sediments may require the archaeologist to conduct further evaluation using hand-dug test units. They will excavate units in a controlled fashion to expose features, collect samples from undisturbed contexts, or to interpret complex stratigraphy. They may also use a test unit or trench excavation to determine if an intact occupation surface is present. They will only use test units when necessary to gather information on the nature, extent, and integrity of subsurface cultural deposits to evaluate the site’s significance. They will conduct excavations using standard archaeological techniques to precisely document the location of cultural deposits, artifacts, and features. The archaeologist will record spatial information, depth of excavation levels, natural and cultural stratigraphy, presence or absence of cultural material, and depth to sterile soil, regolith, or bedrock for each unit on a standard form. They will complete test excavation unit level forms, which will include plan maps for each excavation level and artifact counts and material types, number, and vertical provenience (depth below ECY 070-560 (rev. 06/21) 6 IDP Form surface and stratum association where applicable) for all recovered artifacts. They will draw a stratigraphic profile for at least one wall of each test excavation unit. The archaeologist will screen sediments excavated for purposes of cultural resources investigation through 1/8-inch mesh, unless soil conditions warrant 1/4-inch mesh. The archaeologist will analyze, catalogue, and temporarily curate all prehistoric and historic artifacts collected from the surface and from probes and excavation units. The ultimate disposition of cultural materials will be determined in consultation with the federal agencies (if any), DAHP, Ecology, and the affected tribe(s). Within 90 days of concluding fieldwork, the archaeologist will provide a technical report describing any and all monitoring and resultant archaeological excavations to the Project Lead/Organization, who will forward the report to Ecology, the federal agencies (if any), DAHP, and the affected tribe(s) for review and comment. If assessment activities expose human remains (burials, isolated teeth, or bones), the archaeologist and Project Lead/Organization will follow the process described in Section 6. 8.PROCEEDING WITH WORK The Project Lead/Organization shall work with the archaeologist, DAHP, and affected tribe(s) to determine the appropriate discovery boundary and where work can continue. Work may continue at the discovery location only after the process outlined in this plan is followed and the Project Lead/Organization, DAHP, any affected tribe(s), Ecology, and the federal agencies (if any) determine that compliance with state and federal laws is complete. 9.ORGANIZATION RESPONSIBILITY The Project Lead/Organization is responsible for ensuring: •This IDP has complete and accurate information. •This IDP is immediately available to all field staff at the sites and available by request to any party. •This IDP is implemented to address any discovery at the site. •That all field staff, contractors, and volunteers are instructed on how to implement this IDP. 10.ADDITIONAL RESOURCES Informative Video Ecology recommends that all project staff, contractors, and volunteers view this informative video explaining the value of IDP protocol and what to do in the event of a discovery. The target audience is anyone working on the project who could unexpectedly find cultural resources or human remains while excavating or digging. The video is also posted on DAHP’s inadvertent discovery language website.
