incidental to, the completion of all contract work in accordance with the contract, plans,

PSE design and construction standards and geotechnical information provided in

Exhibit 2. Any bulletins or addenda issued during the time of bidding are to be covered

in the proposal and will become part of any subsequent contract.

The proposal is shown in the three bid schedules in Exhibit 3 and a bid summary. The

bidder is required to bid on all of the bid schedules for the work and contract amount

awarded will be based on the bid summary amount.

Details of work which are necessary to carry out the intent of the contract, or which are

customarily performed, shall not relieve the contractor from performing the omitted

work, but the work shall be performed as if fully and correctly set forth and described in

the contract. The contract bid prices shall be full pay for all work and materials required

based on changed conditions or differing conditions. The Tribe makes no

representations or guarantees regarding the sub-surface soil conditions at the site.

Bidders shall thoroughly examine and be familiar with the drawings and supporting

documents. The failure or omission of any bidder to receive or examine any form,

instrument, addendum or other document or to visit the site and acquaint themselves

with conditions there, which may have a bearing on construction costs, shall in no way

6. LATE SUBMISSIONS, MODIFICATIONS, AND WITHDRAWAL OF BIDS

6.1 Late Submissions

Any bid received after the exact time specified for submission to Rory McLeod will not

6.2 Erasure and Modifications

The proposal form invites bids on definite construction plans. Only the amounts and

information asked on the proposal form furnished will be considered as the bid, each

bidder shall bid upon the work exactly as provided in the proposal form.

The bids submitted must not contain any erasures, delineations, or other corrections

prior to the exact closing time set for submittal of bids. Submission of withdrawal of bid

shall be submitted by an authorized representative of the bidder and must have their

period exceeding sixty (60) calendar days. Negligence on the part of the bidder in

preparing the bid confers no rights for the withdrawal of the bid after it has been

opened.

Page 6 of 41

7. PERMITS AND TAXES

There are no permits required to be obtained by the Contractor, and no State or County

taxes will be charged to the development since all land for the project is currently in

Trust status and located upon a federally recognized Indian Reservation.

8. PAYMENTS

The Tribe will make monthly payments to the Contractor based on progress (by

percentage of completion) on the contractor’s overall budget that sets forth the schedule

of values as required in Section 4.1.

9. INSPECTIONS

The project will be inspected by the Tribe and its designated representatives. The

Contractor shall provide for and include weekly construction progress/inspection

meetings with the Tribe’s project representatives in their bid.

10. DETERMINATION OF LOW BID

Bids will be considered based upon the provisions of Sections 1.02 and 1.03 of the

WSDOT/APWA current edition Standard Specifications, however, generally:

A.

Lump Sum Contracts: Where the lowest base bid submitted by a responsible

bidder for a proposed lump sum contract does not exceed the funds available to finance

the contract, the award of the contract will be made to such lowest responsible bidder

on the basis of the base bid. If the lowest bid submitted by a responsible bidder

exceeds the funds available to finance the contract, the contract may be awarded to that

responsible bidder whose base bid, when reduced by the smallest number of alternates

taken in the sequence specified in the Schedule of Prices, does not exceed such funds,

and is the lowest in comparison with all other bids which are similarly reduced by the

same alternates.

B.

Unit Price Contract: The quantities for which unit prices are indicated in the

proposal form are approximate only and are to be used for the purpose of comparison

of bids and determining the low bid and the amount of the payment and performance

bond required. If a discrepancy exists between the price per unit and the extended

amount of any bid item, the price per unit will control. The total of the extension,

corrected where necessary, will be used for award purposes and to determine the

amount of the performance and payment bond. The Tribe expressly reserves the right

to increase or decrease these quantities during construction and to make reasonable

changes in the design without being responsible to the Contractor for extra costs, loss

or for anticipated profits. Payment will be made on the basis of the actual quantities of

each item of work completed in accordance with the contract documents.

Page 7 of 41

C.

Alternates and Add-on's: If the lowest bid submitted by a responsible bidder

exceeds the funds available to finance the contract, the contract may be awarded to that

responsible bidder whose base bid, when reduced by the smallest number of add on' s

and/or alternate bid items, sequence specified in the Schedule of Prices, does not

exceed such funds, and is the lowest in comparison with all other bids which are

similarly reduced by the same alternates. The Contractor is requested to bid both

proposals; basic bid, alternate bid, and add-ons; the determination of the lowest

responsive bid will be determined as noted above.

In the case of a tie of low bids, award shall be made in accordance with the Tribe’s

written policy and procedure.

The lowest responsible Bidder will be asked to enter into a contract for the total

development schedule of the project. In the event that the Tribe and the highest ranking

contractor are not successful in reaching a contract format, the next highest ranking

bidder will be approached in the same manner. In the event that none of the bidders

reach a successful contract agreement, the Tribe reserves the right to reject all

proposals and re-advertise the project to the General Public using the same general

development conditions.

11. CONSIDERATION OF BIDS

All bids may be rejected if the lowest responsive bid received exceeds the Engineer's

estimate by an unreasonable amount. In the event that all bids received are rejected for

this reason, this project may be deferred to re-advertising for bids until a more

competitive bidding situation exists.

The Tribe reserves the right to reject any/or all proposals, and to waive any informalities

in connection with said proposals or bids.

If any bidder submits more than one proposal for an item, all proposals of that bidder for

all items may be rejected. If the proposal includes a supplemental schedule or

predetermined unit prices for labor and materials or other items for the purpose of

establishing a cost basis on unforeseen contract changes, the Tribe reserves the right

to reject, without impairing the balance of the proposal, any or all such predetermined

unit prices or such supplemental schedules which the Tribe may consider excessive or

unreasonable.

12. SCHEDULE

Bidders are required to establish an overall construction schedule for the entire project,

and include such schedule in their Bid. Failure to submit this schedule will be

considered non-responsive.

Page 8 of 41

13. REPRESENTATIONS AND CERTIFICATIONS

None required

14. BID GUARANTY

A certified check, cashier's check, cash, or a bid bond made payable to the Port Gamble

S’Klallam Tribe for an amount equal to at least five (5) percent of the total amount bid,

and the completed form provided in Exhibit 5 shall accompany each bid as evidence of

good faith and as a guarantee that if awarded the contract, the bidder will execute the

contract and provide the required bond(s).

The successful bidder's bid guarantee payment will be retained until they have entered

into a contract with the Tribe and have furnished a 100 percent payment and

performance bond. The Tribe reserves the right to hold the cash; certified checks,

cashier's check, or bid bond of the three (3) lowest bidders until the successful bidder

has entered into a contract and furnished a payment and performance bond. Once the

project is awarded, the Tribe will return the Bid Guaranty to the non-selected bidders.

Bid bonds shall be furnished by a surety company authorized to do business in the

State of Washington. It is the bidder's responsibility to advise their surety company that

the bond to be furnished relates to work to be performed on an Indian Reservation.

Should the successful bidder fail to enter into a contract and furnish a satisfactory

payment and performance bond within ten (10) business days after their proposal has

been accepted, the cash, certified check, cashier's check or bid bond shall be forfeited

as liquidated damages.

15. PERFORMANCE AND PAYMENT BOND

The successful bidder shall furnish an assurance of completion prior to the execution of

the contract under this solicitation in the form of a payment and performance bond and

in the full amount of the contract price. Such bond shall be furnished by a surety

company and deemed acceptable to the Tribe. Notwithstanding anything herein to the

contrary, said bond(s) shall in all respects comply with the requirements of Chapter

39.08 of the Revised Code of Washington. The expense of this bond shall be borne by

the Contractor.

16. PRECONSTRUCTION CONFERENCE

After award of a contract under this solicitation and prior to the start of work, the

successful bidder will be required to attend a preconstruction conference with

representatives of the Tribe and its Engineer, and other interested parties convened by

the Tribe. The conference will serve to acquaint the participants with the general plan of

the construction operation and all other requirements of the contract. The Tribe will

Page 9 of 41

provide the successful bidder with the date, time, and place of the conference.

17. EQUAL OPPORTUNITY AND NATIVE AMERICAN PREFERENCE

Contractor shall not discriminate against any employee or applicant for employment on

the basis of race, color, ethnicity, religion, age, national origin, gender or disability, with

regard to employment, promotion, demotion, transfer, recruitment, advertising, lay off,

termination, rates of pay or other forms of compensation or selection for training.

This procurement is subject to the Port Gamble S’Klallam Tribal practice of Indian

Preference regarding the use of Port Gamble S’Klallam and Native American

Planning Department, or his successor. The TRIBE’s Project Manager, also authorized to

implement the terms and conditions of this agreement is Rory McLeod. The TRIBE’s Engineer

7. Contractor's Duty to Examine. Contractor represents that it has examined the site of the

Work and has compared the site with the Contract specifications, plans, drawings and other

materials related to the Project. Contractor understands and is knowledgeable about the

facilities and any difficulties attending to the execution of this Contract. No allowance will be

case of a conflict the WSDOT Standard Specifications, current edition will govern.

9. Materials/Approved Equals: All new materials shall be used for this project. Unless an item

provided that the Contractor has specified the substitute brand and model and provided all

descriptive literature, independent test results, product samples, local servicing and part

availability, at the time of contract execution. The decision of TRIBE as to what items are equal

shall be final and conclusive. If TRIBE selects to use a brand that the Contractor represents as

an equal, TRIBE’s acceptance of the item is conditioned on TRIBE’s inspection and testing

after receipt. If TRIBE, in its sole judgment, determines the item is not an equal, the items shall

be returned at Contractor's expense and Contractor shall install the item originally specified.

10. Performance Bond and Insurance. A 100% performance bond is required for this work.

11. Insurance. Contractor shall not commence work under this Contract until all required

insurance has been obtained and approved by TRIBE. Contractor shall maintain all required

a. Workers’ Compensation Insurance. . Contractor shall, during the life of this Contract,

maintain and fully comply with all terms and conditions of the laws of the State of Washington

pertaining to Workers' Compensation, together with any and all amendments and supplements

thereto and any and all regulations promulgated thereunder. For purposes of this contract the

TRIBE adopts the Washington State worker compensation laws (Title 51 RCW), but only to the

limited extent that entitles a worker to receive benefits from the state for injuries a worker incurs

while performing the subject work. TRIBE is not adopting any provisions of the said laws that

could be interpreted to impose liability on TRIBE, and the TRIBE is not waiving sovereign

immunity in this regard.

b. Public Liability and Property Damage Insurance. Contractor shall procure and maintain

during the life of this Contract, a policy of comprehensive general liability insurance, with an

insurance carrier authorized to do business in the State of Washington. The policy shall protect

Contractor and TRIBE from liability imposed by law for damages suffered by any persons

arising out of or resulting from acts or omissions in the performance of this Contract: (1) for

bodily injury or death resulting from accidents or any act or omission by Contractor in the

performance of this Contract, and (2) for injury to or destruction of any property, including

TRIBE property, and including loss of use. The insurance policy shall include coverage for

claims for damages because of bodily injury or death or property damage arising out of the

ownership, maintenance or use of any motor vehicle, including non-owned vehicles. TRIBE

shall be designated in the insurance policy as a primary additional named insured and shall be

provided thirty (30) calendar days written notice of cancellation, non-renewal, or material

change in the coverage provided. The insurance shall be on an "occurrence basis" and shall

be on a Comprehensive General Liability form with coverage to include Blanket Contractor,

Broad Form Property Damage, Personal Injury, Protective Liability and Employers Liability.

Limits shall be at $1,000,000.00 per occurrence, $2,000,000 aggregate. TRIBE's insurance

shall be excess to any other collectible insurance. Contractor shall furnish evidence of the

amount of any deductible or self-insured retention under the policy. Contractor shall be solely

responsible to pay the amount of any deductible or self-insured retention towards the claim

under the policy. TRIBE may require Contractor to furnish evidence of its ability to pay the

amount of any deductible or self-insurance retention.

c. Contractor has the sole obligation to protect and insure itself from loss of its tools and

equipment while at the work site.

12. Proof of Insurance. Contractor shall furnish to TRIBE a Certificate of Insurance coverage

complying with Paragraph 11 above. An up-to-date certificate of insurance must be on file with

TRIBE’s Representative throughout the life of the Contract. TRIBE may, at any time, require

the Contractor to furnish and file with TRIBE a certified true copy of any insurance policy

together with a letter from the insurance carrier verifying that the premium has been paid for the

period indicated. Contractor's failure to obtain or maintain the required insurance shall be

grounds for immediate termination of this Contract. Nothing contained in this paragraph shall

be construed as limiting the extent of Contractor' liability under this Contract.

13. Payment Terms TRIBE shall pay Contractor on the basis of monthly progress payment

requests to the TRIBE’s Project Manager by the tenth (10th) calendar day of each month. Each

progress payment request shall state the date, identify this Project and include a brief

description of the services performed in the preceding month. TRIBE will pay up to ninety

percent (90%) of the actual work completed as identified in the request and approved by the

TRIBE’s Representative, with payment to be made within seven (7) calendar days of TRIBE

approving the request. As to any part of the request TRIBE’s Representative disapproves,

TRIBE will request clarification or additional supporting documentation from Contactor and the

parties will make a good faith effort to reconcile their differences. Upon resolution of disputed

request amounts, any amounts found due shall be paid within seven (7) calendar days of the

reconciliation. Progress payment requests received after the tenth (10th) calendar day of the

month may be processed by TRIBE with the following month’s invoice. Payments made by

TRIBE do not constitute a waiver of any claims by TRIBE against Contractor concerning or

arising out of this Agreement. Contractor’s acceptance of payment for particular services

performed under the Agreement constitutes a waiver of all claims by Contractor for that portion

of the Agreement. Acceptance by Contractor of the final payment under this Agreement

constitutes a waiver of all claims under the Agreement. The making of any progress or final

payment does not relieve Contractor from fully complying with the Contract.

14. Final Payment. Final payment of the retained ten percent (10%) of the Contract price will

be approved and made immediately after TRIBE issues its letter of final acceptance of the

work. Before the final payment is released to Contractor, Contractor must provide to TRIBE:

a. A General Release of all claims to TRIBE, using an agreed upon form;

b. A General Release of all claims from all material suppliers and from any other person or

entity who purports to make a claim against any monies retained by TRIBE; and

c. A letter from the State of Washington Department of Labor and Industries verifying that

all industrial insurance and medical aid premiums have been paid.

15. Inspection of Work. All work performed pursuant to this contract shall be subject to

inspection by TRIBE’s Project Manager and Engineer. The TRIBE Project Manager and

Engineer shall have access to Contractor's work where ever it is in progress or being performed

and Contractor shall provide reasonable access for inspection at all times. No inspection by

TRIBE shall relieve Contractor of its responsibility to perform the work correctly or utilizing

competent labor and new materials in strict accordance with the Contract specifications. All

materials or work approved and later found to be defective by TRIBE shall be replaced without

cost to TRIBE.

16. Inspector's Authority. TRIBE Representative, Project Manager and Engineer shall have

the power to reject materials or workmanship that does not fulfill the requirements of the

Contract specifications. Where Contractor disputes the rejection, Contractor may appeal to the

TRIBE’s Executive Director, whose decision shall be final.

17. Equitable Deduction. If TRIBE deems it expedient not to correct work that fails to meet

contract specifications, an equitable deduction from the Contract price shall be made.

18. Testing. Testing shall be performed on the water system and sewer system in accordance

with construction codes and standards that are applicable to this type of work if such work is

performed off an Indian Reservation in Washington state.

19. Contractor's License. Contractor represents that it is a licensed contractor with the

Washington State Department of Labor and Industries, license number __________.

20. Independent Contractor. Contractor is an independent contractor, it being understood that

TRIBE is interested solely in the results of this contract and is relying upon Contractor’s own

judgment and experience to select the means for its performance of this contract. Contractor

and contractor's employees are not and shall not, under any circumstances, be deemed to be

an employees of the TRIBE nor entitled to any benefits provided to TRIBE employees.

Contractor understands it has no authority whatsoever to negotiate or enter into contracts for or

on behalf of TRIBE.

21. Contractor's Employees. Contractor shall provide a competent supervisor to supervise

Contractor's employees on the Project. Contractor shall employ only competent, skilled, faithful

and orderly persons to perform work under this Contract.

22. Drug Free Workplace. TRIBE maintains Drug Free workplace requirements, policies and

procedures applicable to all persons who provide services to the TRIBE. Contractor who

contracts with TRIBE must comply with the Port Gamble S’Klallam TRIBE's Drug Free

workplace requirements. A Contractor who maintains its own drug testing policies and who can

assure TRIBE that it maintains a drug free workplace may be exempt from complying with the

Tribal drug testing procedures. Contractor hereby warrants that any and all personnel

performing work pursuant to this Contract will be drug and alcohol free and represents that it

maintains a drug free workplace. Based on these representations, which the parties

acknowledge TRIBE is expressly relying upon, TRIBE hereby waives the requirement that

Contractor comply with TRIBE's drug testing policies and procedures. TRIBE reserves the right

to immediately test at the Port Gamble S’Klallam TRIBE Wellness Clinic, at Contractor's cost,

any of Contractor's employees or agent who, while working on the Port Gamble S’Klallam

Indian Reservation, appears to be affected by or under the influence of drugs and/or alcohol. A

breach of any portion of this paragraph is hereby deemed a material breach and is cause for

immediate termination of this Contract.

23. Safety. Contractor shall, at all times, exercise adequate precautions for the safety of all

persons, including its employees, in the performance of this Contract and shall comply with

applicable safety laws and regulations. Contractor is solely responsible to furnish safety

equipment to its workers. TRIBE's Representative, Project Manager, or Engineer may, but

does not have any duty to, advise Contractor of a safety violation. Contractor is solely

responsible to make necessary corrections of all safety violations. Failure to correct a safety

violation is a breach of this Contract and is grounds for TRIBE to order Contractor to cease

work until the unsafe condition is corrected. Time and wages lost due to such safety

shutdowns shall not relieve Contractor of any provisions of this Contract and shall be at

Contractor's sole cost and expense.

24. Cleaning Up of Work Site. Contactor shall at all times, at its sole expense, keep the work

site from accumulation of waste materials and debris caused by the work. At the completion of

its daily work, Contractor shall remove all of its waste materials from and about the site and all

of its equipment and surplus materials. In the case of a dispute, TRIBE may remove the debris

and charge such costs to Contractor. TRIBE will not pay for any material that is deposited at a

place other than the storage area approved by TRIBE.

25. Changes in Plans or Quantities. TRIBE, without invalidating this Contract, may by written

direction order extra work or make reasonable changes by altering, adding to or deducting from

the materials, work or labor and the Contract sum shall be adjusted accordingly. All added

work and labor shall be executed under the conditions of the original Contract except that any

claim for extension of time caused thereby shall only be adjusted at the time of ordering such

change. When work under the Contract is deducted, reduced or eliminated, no payment shall

be made to Contractor for anticipated profits on such work.

26. Extra Work. Any claim or order for extra materials, work and labor made necessary by

TRIBE's written request for alterations or additions to the Contract or by reason that no price is

provided in the Contract, shall not be valid unless the parties have agreed on a price and such

price is documented in a written change order executed prior to Contractor commencing such

extra work. If the total amount of change orders will exceed ten percent of the total contract

price, then Tribal Council approval must be obtained before such additional amount exceeding

ten percent becomes an obligation of the TRIBE.

27. Extension of Time to Perform. With the written approval of the TRIBE Representative,

Contractor may be granted additional time to complete the work required under this Contract if,

in the TRIBE Representative's opinion, the additional time requested arises from an

unavoidable delay. Unavoidable delay in the performance of work shall mean and include only

causes beyond the control of Contractor and which Contractor could not have avoided by the

exercise of due care, prudence, foresight and diligence. Delays caused by a person other than

Contractor will be considered an unavoidable delay insofar as the delay necessarily interferes

with the Contractor's completion of the work and such delays are not part of this Contract.

28. Unavoidable Delays. Contractor shall be provided an extension of time for any work that is

delayed through no cause of Contractor but due to poor weather conditions to properly perform

the work. Contractor shall notify TRIBE’s Representative in writing within 10 calendar days of

any such delay and shall spell out the weather conditions that precluded performing the work.

29. Failure to Timely Complete Work. Should the completion of work required under the

Contract be delayed beyond the expiration of the period set in the Contract for completion or

beyond any time extension which had been allowed during the course of the Contract, in

addition to its other remedies, there shall be deducted from the total Contract price of work, for

each calendar day by which such completion was delayed, the sum of $250 per day. Such

sum shall not be considered a penalty but the parties understand and acknowledge that such

sum is deemed to be liquidated damages which TRIBE will suffer by reason of the Contractor's

failure to timely perform the Contract. TRIBE may retain any money due or which becomes due

to Contractor to cover its liquidated damages.

30. Assumption of Risk. Contractor has inspected the site of the Work and on its behalf and on

behalf of its employees assumes all risks associated with working under these conditions and

shall hold TRIBE harmless from all risk of loss, damage, liability, claim and lawsuits resulting

from working under these site conditions.

31. Compliance with Laws. Contractor shall comply with all applicable laws and, before

commencing work, shall obtain all required licenses and permits necessary to perform this

agreement. Contractor is responsible to file all required tax returns and notices. When working

on the Port Gamble S’Klallam Indian Reservation, Contractor and it’s Sub-Contractors shall be

subject to and comply with all Tribal laws and the jurisdiction of the Tribal Court. Contractor

shall indemnify and hold TRIBE harmless from any and all costs, liabilities, or obligations by

reason of the failure of Contractor to comply with any applicable law.

32. Equal Employment/Indian Preference. Contractor shall not discriminate against any

employee or applicant for employment on the basis of race, color, ethnicity, religion, age,

national origin, gender or disability, with regard to employment, promotion, demotion, transfer,

recruitment, advertising, lay off, termination, rates of pay or other forms of compensation or

selection for training. Non-discrimination requirements notwithstanding, in accordance with

Federal Indian preference laws, Contractor shall, in good faith, provide preference and

opportunities for training and employment to Native Americans, including Port Gamble

S’Klallam Tribal members.

33. Assignment/Subcontract of Contract. Contractor shall not assign or subcontract any work

under this contract.

34. Indemnity. Contractor acknowledges that it is solely responsible for the safety of all

persons and property in the performance of this Contract. Contractor assumes the risk of all

damages, loss, costs, penalties and expenses and agrees to defend, indemnify and hold

harmless TRIBE and its officials, employees, retained engineers and architects, against any

and all loss, damage, liability or costs which may be sustained by TRIBE and/or any of the

aforementioned parties, on a account of any claim, legal action or alternative dispute resolution

for the injury or death of any person or damage to property arising out of and in connection with

or incident to Contractor's performance of the Contract

35. Place of Contract/Consensual Contract. Contractor acknowledges and understands that

the TRIBE is a federally recognized, sovereign Indian TRIBE. Contractor represents and states

here that it voluntarily and knowingly enters into this consensual relationship with TRIBE. The

negotiation and execution of this agreement is deemed by the parties to have occurred within

the Port Gamble S’Klallam Indian Reservation. All work identified in this Agreement will be

performed on the Port Gamble S’Klallam Indian Reservation.

36. Dispute Resolution/Choice of Law.

a. Purpose of Dispute Resolution Provisions. The parties intend to resolve their disputes

through direct discussion and, if such is not possible, then through the dispute resolution

framework established below. All stated time frames for resolving disputes may be

lengthened by mutual consent.

b. Direct Discussions. To initiate dispute resolution under this Section, the complaining

party will first submit a written complaint letter to the representative of the party (as identified

in sections 4 and 4 of this Agreement) against whom a dispute is lodged, stating therein the

nature of the dispute, the requested resolution, and the factual basis supporting the

requested resolution. The responding party will, within ten (10) working days of receiving the

complaint letter, provide a written response, stating its agreement or disagreement with the

nature of the dispute and the requested resolution. If the responding party disagrees with

the complaint or the proposed resolution, the written response must provide at least one

alternate resolution and the factual basis supporting such resolution(s). Thereafter, the lead

representatives of each party will, for fifteen (15) working days, make a good faith attempt to

resolve the dispute through one or more direct discussions. If no mutually acceptable

resolution is reached, the lead representatives will prepare a joint statement within 5

business days, which includes a chronology, a synopsis of the discussions which took place

and the last stated positions of each party.

c. Mediation. If direct discussions between the parties fail to resolve the dispute, any

participating party may, within five business days of completing the direct discussion

process, make a written request for mediation to be conducted in Seattle, Washington or at

another place as the parties may agree in writing. If all participating parties agree to engage

in mediation, the parties shall seek a mutually acceptable mediator. If the parties cannot

reach agreement on the selection of the mediator within fifteen (15) working days of the

date the written mediation request letter was received by the other party or parties, the

mediation will be administered by J.A.M.S., Seattle, Washington Office using a J.A.M.S.

mediator and protocol. Enforcement of a mediation agreement reached shall be the same

as enforcement of an arbitration decision as set forth herein. If a party objects to

proceeding with mediation, then mediation may be bypassed, and the dispute resolved

pursuant to arbitration as set forth herein.

d. Binding Arbitration in the Event of Unsuccessful Direct Discussions/Mediation. Should

direct discussions prove unsuccessful in resolving the dispute, and either mediation is not

requested, is bypassed, or is also unsuccessful, either the complaining or responding party

may make a written demand for arbitration before a single arbitrator in Seattle, Washington

or at another place as the parties may agree in writing. If the parties cannot reach

agreement on the selection of the single arbitrator within fifteen (15) working days of the

date the written demand letter was received, the arbitration will be administered by J.A.M.S.,

Seattle, Washington Office using a J.A.M.S. arbitrator. Any arbitrator selected must have a

fundamental knowledge of and at least five (5) years’ legal experience contract law and a

working knowledge of Indian law. The arbitrator shall have the power to establish a

schedule for the hearing which hearing shall be limited to no more than 2 consecutive

business days to be equally divided between the parties, including preliminary discovery to

the extent he or she deems necessary and proper under the circumstances and there shall

not be more than 2 depositions allowed per party, to make reasonable rules and issue

orders necessary for a fair and efficient conduct of the hearing, and to conduct the hearing

and administer oaths and affirmations. The arbitrator’s decision shall be accompanied by an

explanation as to the basis for the award. Each party will pay for its own attorneys’ fees. The

substantially prevailing party shall be entitled to reimbursement from the other party of all

moneys it paid to the arbitrator or J.A.M.S. related to the arbitration proceeding. All

arbitration awards shall be binding upon the parties and non-appealable.

e. Enforcement of Arbitration Award. Upon the issuance of an arbitration award or

mediation agreement, the prevailing party may seek the entry of judgment upon the award

in any court of competent jurisdiction which for purposes of a party’s enforcement against

TRIBE means the Tribal Court, and for TRIBE’s enforcement against Contractor means

federal court based upon diversity jurisdiction or other jurisdiction. If federal court

jurisdiction is not available, Contractor agrees to submit to Kitsap County Superior Court in

Washington for enforcement of the award against Contractor. The court of competent

jurisdiction shall enforce the decision of the arbitrator and shall not modify, correct, alter or

vacate said decision in any way unless the court finds after notice and hearing upon

application of a party to the arbitration, one or more of the following: (1) the arbitration

decision was procured by corruption, fraud or undue means, (2) there was evident

corruption in the arbitrator, or (3) the arbitrator was guilty of the specific misconduct of

refusing to hear evidence pertinent and material to the controversy which prejudiced the

rights of a party. No court shall have jurisdiction to interfere in any way with any pending

arbitration. No party may seek from such court any provisional remedy pending appointment

of the arbitrator or the arbitrator’s rendition of the award. If the court vacates the arbitration

decision, then the court shall direct a rehearing either before the same arbitrator or before a

new arbitrator to be chosen in the manner provided in this section.

f. Limited Waiver of Sovereign Immunity by the Port Gamble S’Klallam TRIBE. Except for

the limited waiver of sovereign immunity provided in this Dispute Resolution Addendum,

nothing in this Agreement shall be construed as a general or specific waiver of the TRIBE’s

sovereign immunity, which immunities are expressly asserted. The Port Gamble S’Klallam

TRIBE hereby grants to Contractor a limited waiver of sovereign immunity solely for the

purpose of dispute resolution as provided in this Addendum and such waiver shall not be

extended to any other person, agency or entity ("Limited Waiver"). This Limited Waiver

applies only to contractual claims arising out of or under this agreement and does not apply

to any non-contractual claims or to claims under any other agreement between the TRIBE

and Contractor. Furthermore, nothing contained in this Limited Waiver shall be construed to

create a contractual relationship with or a cause of action in favor of any third party against

the TRIBE. This Limited Waiver applies only to the enforcement of a mediation agreement

or an arbitration award against the TRIBE, provided such mediation agreement or arbitration

award has been secured in accordance with the provisions of this Agreement. Any

monetary award by any arbitrator or any mediation agreement shall be limited to not exceed

the total monetary amount under this Agreement. This limited waiver of sovereign immunity

is not, and shall not be deemed to be, a consent by the TRIBE to the levy of any judgment,

lien or attachment on any appropriations received from any of the TRIBE’s governmental

agencies and/or enterprises.

g. No Requirement of Exhaustion of Tribal Court Remedies. The parties acknowledge that

under the limited waiver of sovereign immunity provided for herein, the assumption of

jurisdiction by any arbitrator or court of competent jurisdiction shall not be delayed or

curtailed by any doctrine requiring exhaustion of Tribal court remedies.

h. No Consent to State Court For Any Purpose. The TRIBE expressly states and the

Contractor understands and acknowledges that the TRIBE does not consent to the

jurisdiction of the Washington or any other state court for any purpose except if necessary to

enforce an award against Contractor as set forth above.

37. Termination of Contract for Cause. If the Contractor files for bankruptcy, a general

assignment for the benefit of creditors or a receiver appointed on account of Contractor's

insolvency, or if the work is not being properly and diligently performed, TRIBE may serve

written notice upon the Contractor and the Surety which executed the performance bond, of

TRIBE's intent to terminate the Contract. Such notice will contain the general reasons for

termination of the Contract and a demand that the Contractor cure of any alleged breach of

contract to the satisfaction of TRIBE within ten (10) calendar days of receiving the Notice of

Termination for Cause. In the event the Contractor is terminated for cause, any moneys then

due but unpaid to the Contractor shall be set aside until the Project is complete. If the cost to

TRIBE to complete the contract is greater than the sums left to be paid the Contractor, TRIBE

shall set off such sums against the costs to complete the Contact and Contractor shall pay

TRIBE for the additional costs TRIBE incurred to complete the Contact. If the cost to complete

the contract is less than the sum then owing to the Contractor, TRIBE shall release the unpaid

sum to the Contractor upon closing of the Contract.

38. Termination for Convenience. Upon providing seven (7) calendar days' written notice,

TRIBE may terminate this contract for its convenience. If the contract is terminated by TRIBE,

Contractor will be entitled to receive payment, at a pro rata percent of the amount stated in

paragraph 2 above, for all work completed or partially completed to the satisfaction of TRIBE

prior to the termination date. Contractor shall not be entitled to any other compensation

including anticipated profit.

39. Records. For three years after final payment, Contractor shall maintain for inspection by

TRIBE all books, records, documents, and other evidence of Contractor's costs and expenses

under this agreement, to the extent and in such detail as will properly reflect all costs which

Contactor claimed as due under this agreement.

40. Notices. All notices required to be given in writing in this Contract shall be deemed to have

been given on the date of delivery if: (1) sent by electronic mail that is confirmed by a written

hard copy of the notice which is sent by first class, registered or certified mail, or (2) if

personally delivered to the person, and on the third day after mailing if mailed to the person by

first class mail, registered or certified, postage prepaid and addressed to TRIBE or to the

address for each party stated above or another address designated in a notice given in the

same manner.

The timber harvest area is approximately 6.6 acres in total and consists of conifers and

hardwoods. The Contractor shall inspect the site and make their own determination of the timber

quality.

SHARING SPECIFICATIONS

All timber shall be removed from the Raccoon Town project clearing limits as shown on the

project plans, unless otherwise approved by the Project Manager. The Contractor shall provide

the Port Gamble S’Klallam Tribe with 25% of the volume of timber harvested by the Contractor

for firewood processing purposes by others except for cedar, and will be delivered by the

Contractor to a designated site on the Port Gamble S’Klallam Indian Reservation.

LOGGING CONSTRUCTION

The contractor shall be required to attend a pre-logging conference to review cutting line

boundaries, buffers/leave trees, and firewood destination.

The exterior boundaries of the timber harvest/clearing limit area will be flagged with fluorescent

Environmental services, such as chemical analysis of soil and groundwater for possible environmental

contaminants, are not included in our scope of services for this project

PROPOSED DEVELOPMENT

Based on our communications with the project civil engineer (MAP Ltd.) and our review of the available

plan sheets, we understand that the site development will include design and construction of approximately

50 single-family residential lots. We understand that development will also consist of design and

construction of associated roads, utilities, and landscape areas. We also understand that onsite stormwater

management is being considered to manage the runoff from the proposed impervious areas.

SITE DESCRIPTION AND SURFACE CONDITIONS

The project site is located on the northern-most end of the Port Gamble S’Klallam Reservation (APN:

052702-1-001-2005) and covers an area of approximately 40 acres. The site can be accessed from Hood

Canal Drive NE. The site is bounded by Little Boston Road to the east and by Hood Canal Drive Northeast

to the west, which also crosses the south-central portion of the site as shown on Figures 1 & 2 attached to

this report. The site can be access via gravel service road on the north side of Hood Canal Drive Northeast.

The planned development is on upland areas overlooking a west descending slope down to the entrance to

Hood Canal, and the southeast descending slope of a ravine draining southwest to Hood Canal. The highest

elevation of the site is in the north-central portion at 184 feet. The lowest elevation of the site is in the

southeast portion at 90 feet. The western-portion of the site generally slopes to the west at an inclination

of approximately 7.5 degrees (13 percent), from an elevation of approximately 170 to 95 feet. The easternportion of the site generally slopes to the southeast at an inclination of approximately 5 degrees (9 percent),

from an elevation of approximately 170 to 90 feet. Moderate to steep south-southwest descending slopes

located in the west-central portion of the site as well as a southeast descending slope in the east-central

portion of the site have inclinations of up to about 24 degrees (45 percent). These slopes are addressed in

the Geologic Hazards section of this report. Generally, the site is moderately to heavily vegetated with

mature trees and underbrush

GEOLOGIC SETTING

The site lies within the central Puget Lowland. The lowland is part of a regional north-south trending trough

that extends from southwestern British Columbia to near Eugene, Oregon. North of Olympia, Washington,

this lowland is glacially carved, with a depositional and erosional history including at least four separate

glacial advances/retreats. The Puget Lowland is bounded to the west by the Olympic Mountains and to the

east by the Cascade Range. The lowland is filled with glacial and nonglacial sediments.

The Geologic Map Units of Kitsap County Washington, (DNR, April 2017), indicates that the site vicinity

is underlain between Pleistocene continental glacial till and undifferentiated outwash. Glacial till is a

compact deposit of clay, silt, sand, gravel, cobbles, and boulders deposited at the base of the continental

glacier. Undifferentiated outwash consists of proglacial stratified sand, gravel, and cobbles with minor silt

and clays deposited in meltwater and stream environments.

FIELD INVESTIGATION

Soil Borings: Two (2) exploratory soil borings were completed to evaluate the subsurface soil and

groundwater conditions at the site. The soil borings were completed on August 7th and August 8th, 2023

with a subcontracted drill rig. Both of the soil borings were advanced to a depth of 91.5 feet bgs.

Test Pits: Fourteen (14) exploratory test pits were completed in order to evaluate the subsurface soil and

groundwater conditions at the site. The test pits were completed on August 7th and August 8th, 2023 with a

subcontracted excavator and operator. The test pits were excavated to depths ranging from approximately

4.5 feet to 10.0 feet bgs.

A geologist from Krazan and Associates was present during the exploration, examined the soil and geologic

conditions encountered, obtained samples of the different soil types, and maintained logs of the

explorations. Representative samples of the subsurface soils encountered in the geotechnical explorations

were collected and sealed in plastic bags. The soils encountered in the exploration were visually classified

in general accordance with the Unified Soil Classification System (USCS). These samples were transported

to our laboratory for further examination and testing. The approximate locations of the explorations are

shown on the Site Plan in Figure 2.

SOIL PROFILE AND SUBSURFACE CONDITIONS

This section of the report is intended to provide a general description of the subsurface conditions. Detailed

descriptions of the soils exposed in each of the explorations are presented in the exploration logs in

Appendix A.

Organic Topsoil: Our borings and test pits exposed a surficial layer of about 0.2 to 0.5 feet of organic

topsoil.

Native Glacial Soils: Underlaying the organic topsoil, our explorations of the site generally

encountered/exposed unstratified, moist, medium dense to very dense, light brown to gray silty sand with

gravel and cobbles, extending to the explored depths ranging from 4.5 to 91.5 feet bgs. Test pits TP-7 and

TP-9 exposed stratified layers of moist, medium dense and very stiff to hard, gray silt, sand, and gravel.

We interpreted these soils to be native glacial deposits.

Groundwater Observations: The soil borings and test pits were checked for the presence of groundwater

during drilling operations. Groundwater seepage was not observed. However, it is our opinion that perched

groundwater could occur at shallow depths on this property, especially during and after prolonged periods

of wet weather.

Perched water occurs when surface water infiltrates through less dense, more permeable soils and

accumulates on top of a relatively low permeability soil layer. Perched water does not represent a regional

groundwater "table" within the upper soil horizons. Perched water tends to vary spatially and is dependent

upon the amount of rainfall. We would expect the amount of perched water to decrease during drier times

of the year and increase during wetter periods.

Note: Undocumented fill, loose/soft and organic soils were not encountered/exposed in our explorations ,

but may be present in the unexplored areas of the site.

GEOLOGIC HAZARDS

Erosion Concern/Hazard

The Natural Resources Conservation Services (NRCS) map for the Kitsap County Area, Washington

(WA635), classifies the site area as following:

▪

Poulsbo gravelly sandy loam (0 to 6 percent slopes), Hydrologic soil group B/D;

▪

Poulsbo-Ragnar complex (0 to 6% slopes), Hydrologic soil group B/D;

▪

Poulsbo-Ragnar complex (6 to 15% slopes), Hydrologic soil group B/D;

Hydrologic group B/D soils have variable erosion dependent on local groundwater conditions; however,

disturbed soil on steep slopes may erode rapidly if water is allowed to concentrate on slopes.

We have reviewed the Kitsap County Critical Areas map, in which the western slopes as well as slopes

south adjacent to Hood Canal Drive Northeast in the west-central portion of the site are mapped as moderate

erosion hazards. These slopes are mapped as moderate erosion hazard by Kitsap County because they are

steeper than 15 percent with “erodible soils” as classified by the NRCS. During our site visit, we did not

see any evidence of significant erosion or accumulation of surface water. Our exploration generally

exposed/encountered medium dense to very dense and very stiff to hard native glacial soils. Based on our

exploration, it is our opinion that the proposed development should not increase the erosion hazard,

provided that our recommendations are followed for the design and construction.

It has been our experience that soil erosion due to wind can be minimized by limiting the amount of stripped

soil areas exposed during construction activities, frequently wetting the surface soils during construction,

and with proper landscaping of the site following completion of construction. Typically, erosion of exposed

soils will be most noticeable during periods of rainfall. The potential for erosion may be mitigated by the

use of temporary erosion control measures, such as silt fences, hay bales, straw wattles, mulching, control

ditches or diversion trenching, and contour furrowing. The walls of excavations should be covered with

plastic sheeting, or other erosion control surfacing during periods of rainfall. Erosion control measures

should be in place before the onset of wet weather. To minimize erosion concerns, the Erosion and

Sediment Control section of this report should be followed. Stormwater runoff should not be allowed to

flow over or concentrate on the moderate to steep slopes.

Landslide Hazard

We have reviewed the Kitsap County Critical Areas map, in which the south-southwest descending slopes

in the west-central portion of the site as well as a southeast descending slope in the east-central portion of

the site have been mapped as moderate landslide hazard areas.

A visual surficial reconnaissance was performed during our site visits on August 7 and 8, 2023. The westcentral steep slope overlooks Hood Canal Drive Northeast. The south-southwest descending slope ranges

from about 118 to 170 feet in elevation, and has an inclination of about 24 degrees (45 percent). The slope

was heavily vegetated with thick brambles, brush, and mature trees.

The east-central steep slope is a road cut on the north side of Hood Canal Drive Northeast. The southeast

descending slope ranges from about 104 to 122 feet in elevation, and has an inclination of about 32 degrees

(63 percent). The slope was lightly vegetated with grasses, brush, and immature trees.

During our site visit we did not observe signs of recent slide scarps, tension cracks, or slumps within the

site that would indicate current deep-seated instability on the steep slopes within the property. Signs of

shallow soil movement and soil creep, such as curved tree trunks, were not observed on the slopes of the

property. However, it should be noted that soil creep is the gradual, imperceptible downslope movement

of surficial soils under the effect of gravity, and is typical on steep slopes. Additionally, our exploration

generally exposed/encountered medium dense to very dense native glacial soils, which form the core of the

site slopes and are considered to have good shear strength.

The grading plan was not available at the time this report was prepared, however, based on the feasibility

plan provided to us, we understand that the existing steep slopes and associated vegetation will not be

disturbed during or after construction. Based on our exploration, and our review of the available data, and

provided that the recommendations of this report is followed for design and construction, it is our opinion

that the proposed development will not adversely impact the site slopes or vice versa.

The slope stability and setbacks are further discussed in the Slope Stability Section of this report.

Seismic Hazard

The 2018 International Building Code (IBC), Section 1613.2.2, refers to Chapter 20 of ASCE 7-16 for

seismic Site Class Definitions. It is our opinion that the overall soil profile corresponds to Site Class C as

defined by Table 20.3-1 “Site Class Definitions,” according to the ASCE 7-16 Standard. Site Class C

applies to a “very dense soil and soft rock” profile. The seismic site class is based on a soil profile extending

to a depth of 100 feet. The soil explorations on this site extended to a maximum depth of 91.5 feet and this

seismic site class designation is based on the assumption that medium dense to very dense, and stiff to hard

conditions continue below the depth explored.

We referred to the Applied Technology Council (ATC) website and 2018 IBC to obtain values for SS, SMS,

SDS, S1, SM1, SD1, Fa, and Fv. The ATC website utilizes the most updated published data on seismic

Additional seismic considerations include liquefaction potential and amplification of ground motions by

soft soil deposits. The liquefaction potential is highest for loose sand with a high groundwater table. The

native soils primarily consisting of medium dense to very dense granular soils interpreted to underlie the

site are considered to have a low potential for liquefaction and amplification of ground motion.

The Liquefaction Susceptibility Map of Kitsap County, Washington, by Stephen Palmer, et al. (WADNR,

September 2004) indicates that the subject site is mapped as an area of very low to low liquefaction

susceptibility. Based on our explorations and review of the above-mentioned map, it is our opinion that the

site has low liquefaction hazard, and the proposed development should not increase the liquefaction hazard

provided that our recommendations are followed for both design and construction.

CONCLUSIONS AND RECOMMENDATIONS

General

It is our opinion from a geotechnical standpoint that the site is compatible with the planned development,

provided that the geotechnical engineering recommendations presented in this report are included in the

project design and implemented during construction. We recommended that Krazan review the

development plans.

Soil Conditions: Our soil explorations generally encountered competent native glacial soils underlying

organic topsoil, extending to the maximum depths explored, which ranged from 4.5 to 91.5 feet bgs.

Organic debris was encountered at a depth of about 2.0 feet in test pit TP-6. Loose/soft soils, organic debris,

or undocumented fill were not encountered below the topsoil in the other explorations. However, there

may be layers of loose/soft soils, organic materials, or undocumented fill in unexplored areas of the site.

Cobbles were encountered during our exploration. Glacial till deposits often include cobbles and boulders,

which may present some difficulties for excavation and grading on this site.

Generally, the soils exposed/encountered at this site are considered moisture-sensitive and will be easily

disturbed and difficult to compact when wet. We recommend that construction take place during extended

periods of dry weather in the summer months, if possible. If construction is to take place during wet

weather, additional expenses and delays should be expected due to the wet conditions. Additional expenses

could include the need for placing a blanket of rock spalls to protect exposed subgrades and construction

traffic areas. The on-site granular soils may be suitable for use as structural fill material, provided the

moisture content is near optimum and the soil could be suitably compacted to specifications. This will

depend on the moisture content of the soils at the time of construction. Krazan and Associates should be

retained to determine if the on-site soils can be used as structural fill material at the time of construction.

Foundations: Based on our explorations, conventional spread footings supported on medium dense/stiff

or firmer native soil, or on structural fill extending to medium dense/stiff or firmer native soil, should

provide adequate support for the proposed structures. Detailed geotechnical engineering recommendations

for foundation design are presented in this report.

Stormwater Drainage: Proper site grading and drainage should help maintain current stability conditions.

A comprehensive drainage plan will be an important part of a successful development project at this site.

Surface water runoff should not be allowed to develop concentrated flow over the steep slopes on this

property during or after construction. Proper grading and functional drainage systems are important for

maintaining the current stable condition of the site slopes.

We understand that onsite stormwater management systems/ponds are also being considered in the

northwest and southeast portions of the site. We conducted test pits TP-14 and TP-12 in the proposed

stormwater management areas. However, shallow exposure of very low permeability very dense silty sand

in TP-14 and very stiff to hard cohesive soils in TP-12, indicate that onsite stormwater infiltration is not

feasible.

Site Preparation

In general site clearing should include removal of any vegetation and associated root systems; wood;

abandoned utilities; structures including foundations, rubble; and rubbish. After stripping of organic topsoil

is completed, the building pad and pavement areas should be proof-rolled with a loaded tandem-axle dump

truck and be visually inspected to identify any loose/soft areas.

Subgrade Preparation: In the planned structural areas, organic soil and loose/soft soils should be

excavated to expose the underlying firm native soils. The resulting excavations should be filled to the

planned bottom of the structure’s subgrade elevations with suitable soils as per the Structural Fill section

of this report. Based on our soil explorations, we interpret the medium dense/stiff or firmer native load

bearing soils at this site to be about 1 to 2 feet bgs. There may be thicker layers of loose/soft soils, organic

materials, or undocumented fill in unexplored areas of the site.

During wet weather conditions, which typically occur from October through May, subgrade stability

problems and grading difficulties may develop due to excess moisture, disturbance of moisture sensitive

soils and/or the presence of perched groundwater. Earthwork construction during extended periods of wet

weather could create the need to remove wet disturbed soils if they cannot be suitably compacted due to

elevated moisture contents. The soils exposed/encountered at the site are considered moisture-sensitive. If

over-excavation is necessary, it should be confirmed through continuous monitoring and testing by a

qualified geotechnical engineer or geologist. Soils that have become unstable may require drying to near

their optimal moisture content before compaction is feasible. Selective drying may be accomplished by

scarifying or windrowing surficial material during extended periods of dry, warm weather (typically during

the summer months). If the soils cannot be dried back to a workable moisture condition, remedial measures

may be required. Preparation of the site for wet weather conditions may consist of the placement of a layer

of aggregate base for the protection of exposed soils during construction.

It should be understood that even if Best Management Practices (BMPs) for soil protection are implemented

for the wet season, there is a significant chance that additional soil mitigation work will be needed.

Any buried structures encountered during construction should be completely removed and backfilled with

structural fill. Excavations, depressions, or soft and pliant areas extending below the planned subgrade

elevations should be excavated to expose medium dense or firmer soil, and be backfilled with structural

fill. In general, any septic tanks, underground storage tanks, debris pits, cesspools, or similar structures and

deleterious materials should be completely removed. Any concrete footings encountered in the planned

foundation area should be removed to depth of at least 3 feet below proposed footing elevations or as

recommended by the geotechnical engineer. The resulting excavations should be backfilled with structural

fill.

All fill on the sloping areas should be placed as structural fill. Where fills greater than 8 feet are to be

constructed on original ground that slopes at inclinations steeper than 6:1 (horizontal to vertical), benches

should be cut into the existing slope as the filling operations proceed. Each bench should consist of a level

terrace, a minimum of 4 to 8 feet wide (based on the width of the equipment utilized), with the rise to the

next bench held to 4 feet or less. Where fills of comparable height will be constructed on ground that slopes

at an inclination steeper than 4:1 (horizontal to vertical), a keyway should be provided along the toe of the

fill slope in addition to the benches. Each keyway should consist of a level trench at least 8 feet wide and

at least 2 feet deep, with side slopes not exceeding 1:1 (horizontal to vertical), cut into the existing slope.

Permanent fill slopes should be no steeper than 2 to 1 (horizontal to vertical). Fill materials should not be

placed in any section of the slope until the subgrade for that section has been suitably prepared and evaluated

by a representative of the geotechnical engineer. Brush, roots, sod or any other organic, perishable or

unsuitable material should not be placed in the fill slope.

Site grading near the crowns of the reconstructed slopes should be accomplished, such that, excessive sheet

run-off is prevented. The completed slopes should be seeded or otherwise vegetated to protect from future

erosion. Well vegetated slopes at the recommended configuration should be reasonably protected from

typical erosional effects. However, vegetation on the slopes may not provide protection from unusual flow

conditions, such as flood events or concentrations of stormwater runoff occurring on the slopes.

A representative of our firm should be available on request during all grading operations to observe, test

and evaluate earthwork construction. These testing and observation processes are an integral part of our

service, as acceptance of earthwork construction is dependent upon compaction and stability of the material.

The geotechnical engineer may reject any material that does not meet compaction and stability

requirements. Further recommendations, contained in this report, are predicated upon the assumption that

earthwork construction will conform to the recommendations set forth in this section and in the Structural

Fill section of this report.

Structural Fill

Fill placed beneath foundations or other settlement-sensitive structures should be placed as structural fill.

Structural fill, by definition, is placed in accordance with prescribed methods and standards, and is

monitored by an experienced geotechnical professional. Field monitoring procedures would include the

performance of a representative number of in-place density tests to document the attainment of the desired

degree of relative compaction. A representative of the geotechnical engineer should evaluate the subgrade

prior to structural fill placement.

BMP’s should be followed when considering the suitability of the existing materials for use as structural

fill. The native granular soils may be suitable for reuse as structural fill, provided the soil is free of organic

material and debris, and it is within ± 2 percent of the optimum moisture content. Laboratory testing of

some of the on-site soils indicated percentage of silt and clay (passing no. 200 sieve) to be greater than 5.

It should be noted that the on-site soils with silt and clay content greater than 5 percent will be difficult to

compact during the wet weather. Cobbles and boulders were noted at the time of our exploration. Cobbles

and boulders should be screened from the soil prior to use as structural fill. If the on-site soils are

stockpiled for later use as structural fill, the stockpiles should be covered to protect the soil from wet

weather conditions. We recommend that a representative of Krazan & Associates be on site during the

excavation work to determine which soils are suitable for placement as structural fill.

Imported, all weather granular structural fill material should consist of well-graded gravel or a sand and

gravel mixture with a maximum grain size of 3 inches and less than 5 percent fines (material passing the

U.S. Standard No. 200 Sieve). Structural fill can also consist crushed rock, rock spalls and controlled

density fill (CDF). All structural fill material should be submitted for approval to the geotechnical engineer

at least 48 hours prior to delivery to the site.

Structural fill soils should be placed in horizontal lifts not exceeding 8 inches in thickness prior to

compaction, moisture-conditioned as necessary, (moisture content of soil shall not vary by more than ±2

percent of optimum moisture) and the material should be compacted to at least 95 percent of the maximum

dry density based on ASTM D1557 Test Method. In-place density tests should be performed on all

structural fill to document proper moisture content and adequate compaction. Additional lifts should not

be placed if the previous lift did not meet the compaction requirements or if soil conditions are not

considered stable.

Temporary Excavations

The on-site soils have variable cohesion strengths, therefore the safe angles to which these materials may

be cut for temporary excavations is limited, as the soils may be prone to caving and slope failures in

temporary excavations deeper than 4 feet. Temporary excavations in the existing materials should be sloped

no steeper than 1H:1V where room permits. Flatter inclinations may be necessary where caving conditions,

and groundwater seepage are encountered. Steeper cuts up to ½H:1V may be feasible in the very dense

glacial soil.

All temporary cuts should be in accordance with Washington Administrative Code (WAC) Part N,

Excavation, Trenching, and Shoring. The temporary slope cuts should be visually inspected daily by a

qualified person during construction work activities and the results of the inspections should be included in

daily reports. The contractor is responsible for maintaining the stability of the temporary cut slopes and

minimizing slope erosion during construction. The temporary cut slopes should be covered with plastic

sheeting to help minimize erosion during wet weather and the slopes should be closely monitored until the

permanent retaining systems are complete. Materials should not be stored and equipment operated within

10 feet of the top of any temporary cut slope.

A Krazan & Associates geologist or geotechnical engineer should observe the temporary cut slopes, at least

periodically, during the excavation work. The reason for this is that all soil conditions may not be fully

delineated by the limited sampling of the site from the geotechnical explorations. In the case of temporary

slope cuts, the existing soil conditions may not be fully revealed until the excavation work exposes the soil.

Typically, as excavation work progresses the maximum inclination of the temporary slope will need to be

evaluated by the geotechnical engineer so that supplemental recommendations can be made. Soil and

groundwater conditions can be highly variable. Scheduling for soil work will need to be adjustable, to deal

with unanticipated conditions, so that the project can proceed smoothly and required deadlines can be met.

If any variations or undesirable conditions are encountered during construction, Krazan & Associates

should be notified so that supplemental recommendations can be made.

Slope Stability Analysis

Slope stability analyses were performed using the commercially available GeoStudio Slope/W computer

program. Soil strength parameters for each layer used in our analyses were estimated based on the results

of our exploratory borings, WADNR published geologic maps, and published soil parameter correlations,

and are presented in the table below.

The pseudo-static method was used for the slope stability analyses to estimate the Factor of Safety (FS)

under seismic conditions. The seismic coefficient used in a pseudo-static analysis is typically taken to be

1/2 of the peak ground acceleration (PGA), which was 0.26g in this case.

The results of slope stability analyses are expressed as a Factor of Safety, FS, against displacement failure.

The FS is the ratio of resisting forces to driving forces acting on the slope. A FS of 1.0 represents an

equilibrium state, i.e. resisting forces are equal to driving forces in the modelled slope. A FS of less than

1.0 indicates failure of the modelled slope. Typically, a minimum FS of 1.5 for static conditions and 1.1

for seismic (pseudo-static) conditions are considered adequate in local standard engineering practice. A FS

between 1.0 and 1.5 under static conditions or less than 1.1 under seismic conditions are not adequate due

to the uncertainties in the modeling process.

The results of the slope stability analyses for the static and seismic conditions are presented in the following

table. A graphical presentation of the results of the static and seismic slope stability analyses are presented

in the attached Figures 3 through 6

Uncertainties related to building along the top of steep slopes are typically addressed by the use of building

setbacks. The purpose of the setback is to establish a “buffer zone” between the structure and the top of

the slope so that ample room is allowed for normal slope recession during a reasonable life span of the

structure. In a general sense, the greater the setback, the lower the risk of slope failures to impact the

structure. From a geological standpoint, the setback dimension is based on the slope’s physical

characteristics, such as slope height, surface angle, material composition, and hydrology. Other factors

such as historical slope activity, rate of regression, and the type and desired life span of the development

are important considerations as well.

Based on our exploration, slope stability analysis, and our review of the available data and the proposed

development, it is our opinion that the proposed development will not adversely impact the site slopes or

vice-versa. A 10-foot setback from a minimum of 25-foot buffer from 40 percent or greater steep slopes

will be adequate.

This buffer should not to be disturbed or modified through placement of any fill or removal of the existing

vegetation. No material of any kind should be placed on the buffer or slope or be allowed to reach the

slope, such as excavation spoils, lawn clippings and other yard waste, trash, and soil stockpiles.

Replacement of vegetation in the undisturbed buffer area should be performed in accordance with the Kitsap

County code. Any proposed development within the setback area should be the subject of a specific

geotechnical evaluation. Under no circumstances should water be allowed to concentrate on the steep

slopes. Any sloping areas disturbed during construction should be planted with vegetation as soon as

practical to reduce the potential for erosion.

Shallow Foundations

General: The proposed structures may be supported on a conventional spread foundation system bearing

on the medium dense/stiff or firmer native soils or on structural fill including granular soils, rock spalls or

CDF extending to the medium dense/stiff or firmer native soils. Based on our soil explorations, we

interpreted the medium dense/stiff or firmer native load bearing soils at this site to be approximately one to

two feet bgs. For the bearing capacity and settlement analyses, we have assumed following structural loads:

•

Floor Loads: 100 to 200 pounds per square foot (psf)

•

Column Loads: 50,000 to 75,000 pounds

•

Wall Loads: 2,500 pounds per lineal foot

Soil Bearing: Footings supported as mentioned-above, may be designed using an allowable soil bearing

pressure of 2,500 pounds per square foot (psf) for dead plus live loads. This value may be increased by

1/3 for short duration loads such as wind or seismic loading. A representative of Krazan and Associates

should evaluate the foundation bearing soil and observe structural fill placement, where utilized.

For frost protection and bearing capacity considerations, exterior footings should have a minimum

embedment depth of 18 inches below pad subgrade (soil grade) or adjacent exterior grade, whichever is

lower. Footing widths should be based on the anticipated loads and allowable soil bearing pressure.

Footings should have a minimum width of at least 12 inches regardless of load. Water should not be allowed

Krazan & Associates, Inc.

Page No. 14

to accumulate in footing trenches. All loose or disturbed soils should be removed from the foundation

excavations prior to placing concrete.

Structural Fill in Footing Areas: Structural fill placed for foundation support should follow these

recommendations. If structural fill consisting of granular soils or rock spalls are used, then the foundation

excavations would need to be widened on both sides of the footing a distance equal to one-half of the depth

of the over-excavation below the bottom of the footing. Structural fill consisting of granular soils should

be compacted to at least 95 percent of the maximum dry density based on ASTM Test Method D1557. To

reduce the volume of extra excavation needed for the footing trenches and to simplify structural fill

placement, it may be practical to place CDF to fill the deeper footing trenches to the planned footing

subgrade elevations. If CDF is used, the trench may be excavated only slightly wider (6 inches wider on

each side) than the footing.

Potential Foundation Settlement: For foundations constructed as recommended, the total settlement is

not expected to exceed 1-inch. Differential settlement should be less than ½-inch. Most settlement is

expected to occur during construction, as the loads are applied. However, additional post-construction

settlement may occur if the foundation soils are flooded or saturated. It should be noted that the risk of

liquefaction is considered low, given the composition and density of the native glacial soils.

Design Parameters – Lateral Resistance: Resistance to lateral displacement can be computed using an

allowable friction factor of 0.40 acting between the bases of foundations and the supporting subgrade soil.

Lateral resistance for footings can alternatively be developed using an allowable equivalent fluid passive

pressure of 300 pounds per cubic foot (pcf) acting against the appropriate vertical footing faces (neglecting

the upper 12 inches). The allowable friction factor and allowable equivalent fluid passive pressure values

include a factor of safety of 1.5. The frictional and passive resistance of the soil may be combined without

reduction in determining the total lateral resistance.

Foundation Drainage: Seasonal rainfall, water run-off, and the normal practice of watering trees and

landscaping areas around the proposed structures, should not be permitted to flood and/or saturate

foundation subgrade soils. To reduce the buildup of water within the footing areas, continuous footing

drains (with cleanouts) should be provided at the bases of the footings. The footing drains should consist

of a minimum 4-inch diameter rigid perforated PVC pipe, sloped to drain, with perforations placed near the

bottom and enveloped in all directions by washed rock and wrapped with filter fabric to limit the migration

of silt and clay into the drain.

Floor Slabs and Exterior Flatwork

The floor slab and exterior flatwork subgrade should be prepared in accordance with the recommendations

presented in the Site Preparation section of this report, and may be designed using a modulus of subgrade

reaction value of k = 200 pounds per cubic inch (pci).

Krazan & Associates, Inc.

Page No. 15

In areas where it is desired to reduce floor dampness, such as areas covered with moisture sensitive floor

coverings, we recommend that concrete slab-on-grade floors be underlain by a water vapor retardant

system. The system should consist of a vapor retardant sheeting underlain by a capillary break consisting

of a minimum of 4-inches of compacted clean (less than 5 percent passing the U.S. Standard No. 200 Sieve),

open-graded coarse rock of ¾-inch maximum size. The vapor retardant sheeting should be protected from

puncture damage. In addition, ventilation of the structure may be prudent to reduce the accumulation of

interior moisture.

The exterior flatwork should be placed separately in order to act independently of the walls and foundation

system.

Lateral Earth Pressures and Retaining Walls

We have developed criteria for the design of retaining or below grade walls. Our design parameters are

based on retention of the native soils or structural fill. The parameters are also based on level, well-drained

wall backfill conditions. Walls may be designed as “restrained” retaining walls based on “at-rest” earth

pressures, plus any surcharge on top of the walls as described below, if the walls are braced to restrain

movement and/or movement is not acceptable. Unrestrained walls may be designed based on “active” earth

pressure, if the walls are not part of the buildings and some movement of the retaining walls is acceptable.

Acceptable lateral movement equal to at least 0.2 percent of the wall height would warrant the use of

“active” earth pressure values for design. The following table, titled Wall Design Criteria, presents the

recommended soil related design parameters for retaining walls with well-drained level backfill.

If vehicular loads are expected to act behind the wall within a horizontal distance of less than or equal to

one-half of the wall height, then a live load surcharge should be applied for the design. In this case, we

recommend the addition of vehicle surcharges of 70 psf and 100 psf to the active and at-rest earth pressures,

respectively.

Page No. 16

The stated lateral earth pressures do not include the effects of hydrostatic pressure generated by water

accumulation behind the retaining walls or loads imposed by construction equipment, foundations or

roadways adjacent to the wall (surcharge loads). To minimize the lateral earth pressure and reduce the

buildup of water pressure against the walls, continuous footing drains (with cleanouts) should be provided

at the bases of the walls. The footing drains should consist of a minimum 4-inch diameter rigid PVC

perforated pipe, sloped to drain, with perforations placed near the bottom. The drainpipe should be

enveloped by 6 inches of washed gravel in all directions wrapped in filter fabric to prevent the migration

of silt and clay into the drain.

The wall fills adjacent to and extending a lateral distance of at least 2 feet behind the walls should consist

of free-draining granular material. All free-draining backfill should contain less than 3 percent fines

(passing the U.S. Standard No. 200 Sieve) based upon the fraction passing the U.S. Standard No. 4 Sieve

with at least 30 percent of the material being retained on the U.S. Standard No. 4 Sieve. Alternatively, a

drainage composite may be used. It should be realized that the primary purpose of the free-draining material

is the reduction of hydrostatic pressure. Some potential for the moisture to contact the back face of the wall

may exist, even with treatment, which may require that more extensive waterproofing be specified for walls,

which require interior moisture sensitive finishes.

We recommend that the wall fill be compacted to at least 95 percent of the maximum dry density based on

ASTM D1557 Test Method. In-place density tests should be performed to verify adequate compaction.

Soil compactors place transient surcharges on the backfill. Consequently, only light hand operated

equipment is recommended for fill compaction within 3 feet of walls so that excessive stress is not imposed

on the walls.

Erosion and Sediment Control

Erosion and sediment control (ESC) is used to minimize the transportation of sediment to wetlands, streams,

lakes, drainage systems, and adjacent properties. Erosion and sediment control measures should be taken

and these measures should be in general accordance with local regulations. At a minimum, the following

basic recommendations should be incorporated into the design of the erosion and sediment control features

of the site:

1)

Phase the soil, foundation, utility, and other work, requiring excavation or the disturbance of the

site soils, to take place during the dry season (generally May through September). However,

provided precautions are taken using Best Management Practices (BMPs), grading activities can

be undertaken during the wet season (generally October through April). It should be noted that this

typically increases the overall project cost.

2)

All site work should be completed and stabilized as quickly as possible.

3)

Additional perimeter erosion and sediment control features may be required to reduce the

possibility of sediment entering the surface water. This may include additional silt fences, silt

Krazan & Associates, Inc.

fences with a lower Apparent Opening Size (AOS), construction of a berm, or other filtration

systems.

4)

Any runoff generated by dewatering discharge should be treated through construction of a sediment

trap if there is sufficient space. If space is limited other filtration methods will need to be

incorporated.

5)

Surface water runoff should not be allowed to develop concentrated flow over the steep slopes on

this property during or after construction.

Groundwater Influence on Structures and Earthwork Construction

Groundwater seepage was not encountered in our test pits or soil borings at the time of our exploration. It

should be recognized that groundwater elevations may fluctuate with time. The groundwater level will be

dependent upon seasonal precipitation, irrigation, land use, and climatic conditions, as well as other factors.

Therefore, groundwater levels at the time of the field investigation may be different from those encountered

during the construction phase of the project. The evaluation of such factors is beyond the scope of this

report.

If groundwater seepage is encountered during construction, we should observe the conditions to determine

if dewatering will be needed. Design of temporary dewatering systems to remove groundwater should be

the responsibility of the contractor. If earthwork is performed during or soon after periods of precipitation,

the subgrade soils may become saturated. These soils may “pump,” and the materials may not respond to

densification techniques. Typical remedial measures include: disking and aerating the soil during dry

weather; mixing the soil with drier materials; removing and replacing the soil with an approved fill material.

A qualified geotechnical engineering firm should be consulted prior to implementing remedial measures to

observe the unstable subgrade conditions and provide appropriate recommendations.

Drainage and Landscape

Special attention to the drainage and irrigation adjacent to the buildings is recommended. Grading should

establish drainage away from the structures and this drainage pattern should be maintained. Water should

not be allowed to collect adjacent to the structures. Excessive irrigation within landscaped areas adjacent

to the structure should not be allowed to occur.

Surface water runoff should not be allowed to develop concentrated flow over the steep slopes on this

property during or after construction. Proper grading and functional drainage systems are important for

maintaining the currently stable condition of the site slopes.

The ground surface should slope away from building pads and pavement areas, toward appropriate drop

inlets or other surface drainage devices. It is recommended that adjacent exterior grades be sloped a

minimum of 2 percent for a minimum distance of 5 feet away from structures. Roof drains should be

tightlined away from foundations. Roof drains should not be connected to the footing drains.

Krazan & Associates, Inc.

Offices Serving the Western United States

KA Project No. 102-23017

Proposed North Kloomachin Subdivision

October 2, 2023

Page No. 18

Pavement areas should be inclined at a minimum of 1 percent and drainage gradients should be maintained

to carry all surface water to collection facilities, and suitable outlets. These grades should be maintained

for the life of the project.

Utility Trench Backfill

We recommend that utility trench backfill be placed in general accordance with typical recommendations

for structural fill placement. A firm and unyielding subgrade should allow for the proper placement of

subsurface utilities. This could include the placement of geotextile and quarry rock in the bottom of utility

trenches prior to placement of pipe bedding, utilities and trench backfill.

Utility trenches should be excavated according to accepted engineering practices following OSHA

(Occupational Safety and Health Administration) standards, by a contractor experienced in such work. The

responsibility for the safety of open trenches should be borne by the contractor. Traffic and vibration

adjacent to trench walls should be minimized; cyclic wetting and drying of excavation side slopes should

be avoided. Depending upon the location and depth of some utility trenches, groundwater flow into open

excavations could be experienced, especially during or shortly following periods of precipitation.

All utility trench backfill for this project should follow the recommendation as per the Structural Fill section

of this report. Utility trench backfill placed in or adjacent to buildings and exterior slabs should be

compacted to at least 95 percent of the maximum dry density based on ASTM Test Method D1557. The

upper 5 feet of utility trench backfill placed in pavement areas should be compacted to at least 95 percent

of the maximum dry density based on ASTM Test Method D1557. Below 5 feet, utility trench backfill in

pavement areas should be compacted to at least 90 percent of the maximum dry density based on ASTM

Test Method D1557.

Pipe bedding should be in accordance with the pipe manufacturer's recommendations. The contractor is

responsible for removing all water-sensitive soils from the trenches regardless of the backfill location and

compaction requirements. The contractor should use appropriate equipment and methods to avoid damage

to the utilities and/or structures during fill placement and compaction.

Pavement Design

The pavement subgrade should be prepared in accordance with the recommendations presented in the Site

Preparation section of this report. It should be noted that subgrade soils that have relatively high silt

contents may be highly sensitive to moisture conditions. The subgrade strength and performance

characteristics of a silty subgrade material may be dramatically reduced if it becomes wet. Therefore, we

recommend that the pavement subgrade not be exposed for long periods, especially during wet weather.

Traffic loads were not provided, however, based on our knowledge of the proposed project, we expect the

traffic to range from light duty (passenger automobiles) to heavy duty (firetrucks). The following tables

show the minimum recommended pavement sections for both light duty and heavy-duty traffic loads.

The pavement specification in Appendix C provides additional recommendations. The asphaltic concrete

depth in the flexible pavement tables should be a surface course type asphalt, such as Washington

Department of Transportation (WSDOT) ½ inch HMA. The rigid pavement design is based on a Portland

Cement Concrete (PCC) mix that has a 28-day compressive strength of 4,000 pounds per square inch (psi)

with a fiber mesh. The design is also based on a concrete flexural strength or modulus of rupture of 575

psi.

Testing and Inspection

A representative of Krazan & Associates, Inc. should be present at the site during the earthwork activities

to confirm that actual subsurface conditions, including foundation bearing soils, are consistent with those

exposed during our exploratory field work. This activity is an integral part of our services as acceptance of

earthwork construction is dependent upon compaction testing and stability of the material. This

representative can also verify that the intent of our recommendations has been incorporated into the project

design and construction. Krazan & Associates, Inc. will not be responsible for grades or staking, since this

LIMITATIONS

This report has been prepared for the exclusive use of MAP Ltd. and their assigns, for the specific

application to the subject site. Geotechnical engineering is one of the newest divisions of Civil Engineering.

This branch of Civil Engineering is constantly improving as new technologies and understanding of earth

sciences improves. Although your site was analyzed using the most appropriate current techniques and

methods, undoubtedly there will be substantial future improvements in this branch of engineering. In

addition to improvements in the field of geotechnical engineering, physical changes in the site either due

to excavation or fill placement, new agency regulations, or possible changes in the proposed structure after

the time of completion of the soils report may require the soils report to be professionally reviewed. In

light of this, the owner should be aware that there is a practical limit to the usefulness of this report without

critical review. Although the time limit for this review is strictly arbitrary, it is suggested that three years

be considered a reasonable time for the usefulness of this report.

Foundation and earthwork construction are characterized by the presence of a calculated risk that soil and

groundwater conditions have been fully revealed by the original geotechnical investigation. This risk is

derived from the practical necessity of basing interpretations and design conclusions on limited sampling

of the earth. Our report, design conclusions, and interpretations should not be construed as a warranty of

the subsurface conditions. Actual subsurface conditions may differ, sometimes significantly, from those

indicated in this report.

The recommendations made in this report are based on the assumption that soil conditions do not vary

significantly from those encountered during our field investigation. The findings and conclusions of this

report can be affected by the passage of time, seasonal weather conditions, manmade influences such as

construction on or adjacent to the site, and natural events such as earthquakes, slope instability, flooding,

or groundwater fluctuations. If any variations or undesirable conditions are encountered during

construction, the geotechnical engineer should be notified so that supplemental recommendations can be

made.

The conclusions of this report are based on the information provided regarding the proposed construction.

If the proposed construction is relocated or redesigned, the conclusions in this report may not be valid. The

geotechnical engineer should be notified of any changes so that the recommendations can be reviewed and

re-evaluated.

Misinterpretations of this report by other design team members can result in project delays and cost overruns. These risks can be reduced by having Krazan & Associates, Inc. involved in the design team’s

meetings and discussions prior to and following submission of the geotechnical report. Krazan &

Associates, Inc. should also be retained to review pertinent elements of the design team’s plans and

specifications. To reduce the risk of contractors misinterpreting the recommendations of this report, Krazan

& Associates should participate in pre-bid and preconstruction meetings, and provide construction

observations and testing during the site work.

This report is a geotechnical engineering investigation with the purpose of evaluating the soil conditions in

terms of foundation design. The scope of our geotechnical engineering services did not include any

environmental site assessment for the presence or absence of hazardous and/or toxic materials in the soil,

groundwater or atmosphere, or the presence of wetlands. Any statements, or absence of statements, in this

report or on any boring log regarding odors, unusual or suspicious items, or conditions observed are strictly

for descriptive purposes and are not intended to convey engineering judgment regarding potential hazardous

and/or toxic assessments.

The geotechnical information presented herein is based upon professional interpretation utilizing standard

engineering practices and a degree of conservatism deemed proper for this project. It is not warranted that

such information and interpretation cannot be superseded by future geotechnical developments. We

emphasize that this report is valid for this project as outlined above, and should not be used for any other

site. Our report is prepared for the exclusive use of our client. No other party may rely on the product of

our services unless we agree in advance to such reliance in writing.

APPENDIX A

FIELD INVESTIGATION AND LABORATORY TESTING

Field Investigation

The field investigation consisted of a surface reconnaissance and a subsurface exploration program. Two

(2) geotechnical soil borings and fourteen (14) test pits were conducted and sampled on August 7th and 8th,

2023 to evaluate the subsurface soil and groundwater conditions at the project site. The soil borings,

designated B-1 and B-2, were advanced to a depth of 91.5 feet bgs using a subcontracted drill rig and

operator under the direction of a Krazan field geologist.. The test pits were excavated on August 7th and

8th, to depths ranging from 4.5 to 10.0 feet bgs. The approximate boring and test pit locations are shown

on the Site Plan (Figure 2). The depths shown on the attached boring and test pit logs are from the existing

ground surface at the time of our exploration.

Soil boring samples were obtained by using the Standard Penetration Test (SPT) as described in ASTM

Test Method D1586. The Standard Penetration Test and sampling method consists of driving a standard

2-inch outside-diameter, split barrel sampler into the subsoil with a 140-pound hammer free falling a

vertical distance of 30 inches. The summation of hammer-blows required to drive the sampler the final

12-inches of an 18-inch sample interval is defined as the Standard Penetration Resistance, or N-value. The

blow count is presented graphically on the boring log in this appendix. The resistance, or “N” value,

provides a measure of the relative density of granular soils or of the relative consistency of cohesive soils.

A field geologist from Krazan and Associates was present during the explorations, continuously examined

and visually classified the soils in general accordance with the Unified Soil Classification System (USCS),

and maintained logs of the explorations, which are presented in this appendix. Representative samples of

the soils encountered in the geotechnical explorations were collected and transported to our laboratory for

further examination and testing.

Laboratory Testing

The laboratory testing program was developed primarily to determine the index properties of the soils.

Test results were used for soil classification and as criteria for determining the engineering suitability of

the surface and subsurface materials encountered. Sieve analysis and natural moisture content tests were

performed on selected samples. The laboratory test results are included in this appendix.
