G.6.17. Contractor's Responsibility for the Work: Until written acceptance by the Engineer, as provided for in these specifications, the work shall be under the charge and care of the Contractor and he shall take every precaution to prevent injury or damage to the work or any part thereof by action of the elements or from any other cause whatsoever, whether arising from the execution or non-execution of the work. The Contractor shall rebuild, restore and G-17 make good at his own cost and expense, all injuries or damages to any part of the work occasioned by any of the herein above causes. 6.6.18. Contractor's Insurance: The Contractor at his own expense shall purchase, maintain and keep in force during the life of this contract, adequate insurance that will protect the Contractor and/or any Additional Insured from claims which may arise out of or result from operations under this contact. The insurance required shall provide adequate protections from all claims, whether such operations be by the Contractor or by any Additional Insured or by any Subcontractor or by anyone directly or indirectly employed by any of them, or by anyone whose acts of any of them may be liable and from any special hazards, such as blasting, which may be encountered in the performance of this contract in the amounts as shown below in sub-paragraph (A).

The Contractor shall not commence work on any Contract in the Town of Westlake until the Contractor has obtained all the insurance required under this paragraph and such insurance has been approved by the Town. G.6.19. Workers' Compensation Insurance Coverage: (A) Definitions: Certificate of coverage ("certificate") - A copy of a certificate of insurance, a certificate of authority to self-insure issued by the commission, or a coverage agreement (TWCC-81, TWCC-82, TWCC-83, or TWCC-84) showing statutory workers' compensation insurance coverage for the person's or entity's employees providing services on a project for the duration of the project. Duration of the project - Includes the time from the beginning of the work on the project until the contractor's/person's work on the project has been completed and accepted by the Town. Persons providing services on the project ("subcontractor" in §406.096) - Includes all persons or entities performing all or part of the services the contractor has undertaken to perform on the project, regardless of whether that person contracted directly with the contractor and regardless of whether that person has employees. This includes without limitation, independent contractors, subcontractors, leasing companies, motor carriers, owner-operators, employees of any such entity, or employees of any entity which furnishes persons to provide services on the project. "Services" include, without limitation, providing, hauling, or delivering equipment or materials, or providing labor, transportation, or other service related to a project. "Services" does not include activities unrelated to the project, such as food/beverage vendors, office supply deliveries, and delivery of portable toilets. G-19 (B) The contractor shall provide coverage, based on proper reporting of classification codes and payroll amounts and filing of any coverage agreements, which meets the statutory requirements of Texas Labor Code, Section 401.011(44) for all employees of the contractor providing services on the project, for the duration of the project. (C) The contractor must provide a certificate of coverage to the Town prior to being awarded the contract. (D) If the coverage period shown on the contractor's current certificate of coverage ends during the duration of the project, the contractor must, prior to the end of the coverage period, file a new certificate of coverage with the Town showing that coverage has been extended. (E) The contractor shall obtain from each person providing services on a project, and provide to the Town: (1) A certificate of coverage, prior to that person beginning work on the project, so the Town will have on file certificates of coverage showing coverage for all persons providing services on the project; and (2) No later than seven days after receipt by the contractor, a new certificate of coverage showing extension of coverage, if the coverage period shown on the current certificate of coverage ends during the duration of the project. (F) The contractor shall retain all required certificates of coverage for the duration of the project and for one year thereafter. (G) The contractor shall notify the Town in writing by certified mail or personal delivery, within 10 days after the contractor knew or should have known, of any change that materially affects the provision of coverage of any person providing services on the project. (H) The contractor shall post on each project site a notice, in the text, form and manner prescribed by the Texas Workers' Compensation Commission, informing all persons providing services on the project that they are required to be covered, and stating how a person may verify coverage and report lack of coverage. (1) The contractor shall contractually require each person with whom it contracts to provide services on a project, to: (1) Provide coverage, based on proper reporting of classification codes and payroll amounts and filing of any coverage agreements, which meets the statutory requirements of Texas Labor Code, Section 401.011(44) for all of its employees providing services on the project, for the duration of the project; (2) Provide to the contractor, prior to that person beginning work on the project, a certificate of coverage showing that coverage is being provided for all employees of the person providing services on the project, for the duration of the project; G-20 (3) Provide the contractor, prior to the end of the coverage period, a new certificate of coverage showing extension of coverage, if the coverage period shown on the current certificate of coverage ends during the duration of the project; (4) Obtain from each other person with whom it contracts, and provide to the contractor: (a) A certificate of coverage, prior to the other person beginning work on the project; and (b) A new certificate of coverage showing extension of coverage, prior to the end of the coverage period, if the coverage period shown on the current certificate of coverage ends during the duration of the project; (5) Retain all required certificates of coverage on file for the duration of the project and for one year thereafter; (6) notify the Town in writing by certified mail or personal delivery, within 10 days after the person knew or should have known, of any change that materially affects the provision of coverage of any person providing services on the project; and (7) Contractually require each person with whom it contracts, to perform as required by paragraphs (1) - (7), with the certificates of coverage to be provided to the person for whom they are providing services. (J) By signing this contract or providing or causing to be provided a certificate of coverage, the contractor is representing to the Town that all employees of the contractor who will provide services on the project will be covered by workers' compensation coverage for the duration of the project, that the coverage will be based on proper reporting of classification codes and payroll amounts, and that all coverage agreements will be filed with the appropriate insurance carrier or, in the case of a self-insured, with the commission's Division of Self-Insurance Regulation. Providing false or misleading information may subject the contractor to administrative penalties, criminal penalties, civil penalties, or other civil actions. (K) The contractor's failure to comply with any of these provisions is a breach of contract by the contractor which entitles the Town to declare the contract void if the contractor does not remedy the breach within ten days after receipt of notice of breach from the Town. Section G.7. - Prosecution and Progress G.7.1. Assignment and Subletting: The Contractor further agrees that he will retain personal control and will give his personal attention to the fulfillment of this contract and that he will not assign by Power of Attorney, or otherwise, or sublet said contract, without the written consent of the Town, and that no part of the work will be sublet to anyone objectionable to the Town Engineer. G-21 G.7.2. Prosecution of the Work: The Contractor shall begin the work to be performed under this contract within the time limit stated in these specifications, and shall conduct the work in such a manner and with sufficient equipment, materials, and labor as is necessary to insure its completion within the time limit. The sequence of all construction operations shall be at all times as directed by or approved by the Engineer. Such direction or approval by the Engineer shall not relieve the Contractor from the full responsibility of the complete performance of the contract. Should the prosecution of the work be discontinued by the Contractor, he shall notify the Engineer at least twenty-four hours in advance of resuming operation. G.7.3. Limitation of Operations: The work shall be so conducted as to create a minimum amount of inconvenience to the public. At any time when, in the judgment of the Engineer, the Contractor has obstructed or closed or is carrying on operations on a greater portion of the street or public way than is necessary for the proper execution of the work, the Engineer may require the Contractor to finish the sections on which work is in progress before operations are started on any additional section. GJA Time and Order of Completion: It is the meaning and intent of this contract, unless otherwise herein specifically provided, that the Contractor shall be allowed to prosecute his work at such time and seasons, in such order of precedence, and in such a manner as shall be most conducive to economy of construction; provided, however, that the order and the time of prosecution shall be such that the work shall be substantially completed as a whole and in part, in accordance with this contract, the plans and specifications, and within the time of completion designated in the proposal; provided, also, that when the Town is having other work done, either by contract or by its own force, the Engineer may direct the timing of the contract, so that conflict will be avoided and the construction of the various works being done for the Town shall be harmonized. The Contractor shall submit, at such times as may reasonably be requested by the Engineer, a schedule which shall show the order in which the Contractor will start the several parts of the work, and estimated dates of completion of the several parts. G.7.5. Extension of Time: Should the Contractor be delayed in the completion of the work by any act or neglect of the Town or Engineer, or any employee of either, or by other Contractor's employed by the Town, or by changes ordered in the work, or by strikes, lockouts, fires, and unusual delays by common carriers, or unavoidable cause or causes beyond the Contractor's control or by any cause which the Engineer shall decide justifies delay, then an extension of the time shall be allowed for completing the work, sufficient to compensate for the delay, the amount of the extension to be determined by the Engineer, provided, however that the Contractor shall give the Engineer prompt notice in writing of the cause of such delay. G.7.6. Hindrances and Delays: No claims shall be made by the Contractor for damages resulting from hindrances or delays from any cause (except where the work is stopped by order of the Town) during the progress of any portion of the work embraced in this contract. In case said work shall be stopped by an act of the Town, then such expense as in the judgment of the Engineer, caused by such stoppage of said work shall be paid for by the Town to the Contractor. G-22 Once the work order is transmitted to the Contractor, the Contractor shall devote both manpower and equipment to the project on a continuous basis each and every workday in sufficient quantity to bring the project to completion without delay. The Town Engineer shall be the sole judge, with appeal only to the Town Council, of whether the Contractor has devoted both manpower and equipment to the project on a continuous basis to bring the project to completion. If the Engineer or his designee should determine the Contractor has failed to diligently prosecute the project and the Town Council does not reverse the decision of the Engineer or his designee, the Town Engineer may have the remaining work performed by another contractor and deduct whatever is paid to the substitute contractor from the Contractor's contract. Failure to comply with the contractual provisions of a Town of Westlake construction contract or failure to diligently pursue a project to completion shall be a basis for the Town Council rejecting a future bid from said Contractor. G.7.7. Failure to Complete on Time: The time of completion of the contract is of the essence. For each working day that any work shall remain uncompleted after the time specified in the proposal and contract, plus any authorized time extension granted in writing by the Town of Westlake, or as automatically increased by additional work or materials ordered after the contract is signed, the sum per day of 11500 of the amount of the contract (to an amount not to exceed $500.00 per day), unless otherwise specified in the special provisions, will be deducted from the moneys due the Contractor, not as a penalty but as liquidated damages. The sum of money thus deducted for such delay, failure or noncompletion is not to be considered as a penalty, but shall be deemed, taken and treated as reasonable liquidated damages, since it would be impracticable and extremely difficult to fix the actual damages. The Contractor shall also indemnify and hold the Town harmless including paying court costs and defense fees from any property damage claims resulting from restriction of access caused by the Contractor's negligent performance or undue delay. G.7.8. Suspension by Court Order: The Contractor shall suspend such part or parts of the work ordered by the court, and will not be entitled to additional compensation by virtue of such court order. Neither will he be liable to the Town in the event the work is suspended by court order. G.7.9. Temporary Suspensions: The Engineer shall have the authority to suspend the work wholly or in part for such period or periods as he may deem necessary due to unsuitable weather conditions as are considered unfavorable for the suitable prosecution of the work. If it should become necessary to stop the work for an indefinite period, the Contractor shall store all materials in such a manner that they will not obstruct or impede the public unnecessarily nor become damaged in any way and he shall take every precaution to prevent damage or deterioration. G.7.10. Abandonment by Contractor: In case the Contractor should abandon and fail or refuse to resume work within ten (10) days after written notification from the Town or the Engineer, when such orders are consistent with the Contract Document, then, and in that case, where a performance bond exists, the Surety on the bond shall be notified in writing and directed to complete the work, and a copy of said notice shall be delivered to the Contractor. G-23 After receiving said notice of abandonment, the Contractor shall not remove from the work any materials, equipment, tools, or supplies then on the job, but the same, together with any materials and equipment under contract for the work may be held for use on the work by the Town of Westlake, the Surety on the construction bond, or another contractor in completion of the work; and the Contractor shall not receive any rental or credit therefore (except when used in connection with Extra Work where credit shall be allowed as provided for under Article G.4.5., Extra Work), it being understood that the use of such equipment and materials will ultimately reduce the cost to complete the work and be reflected in the final settlement. GJA 1. Termination of Contract: The contract will be considered fulfilled, save as provided in any maintenance stipulations, bond, or by law, when all the work has been completed, the final inspection made by the Engineer, and final acceptance and final payment made by the Town. Section G.8. - Measurement and Payment G.8.1. Quantities and Measurement: No extra or customary measurements of any kind will be allowed, but the actual measured and/or computed length, area, solid contents number and weight only shall be considered, unless otherwise specifically provided. G.8.2. Estimated Quantities: This agreement, including the specifications, plans, and estimates, is intended to show clearly all work to be done and material to be furnished hereunder. Where the estimated quantities are shown for the various classes of work to be done and material to be furnished under this contract, they are approximate and are to be used only as a basis for estimating the probable cost of the work and for comparing the proposals offered for the work. It is understood and agreed that the actual amount of work to be done and materials to be furnished under this contract may differ somewhat from these estimates, and that where the basis for payment under this contract is the unit price method, payment shall be for the actual amount of such work done and the material furnished. Where payment is based on the unit price method, the Contractor agrees that he will make no claim for damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually done, the material actually furnished under this contract and the estimated quantities contemplated and contained in the proposal; provided, however, that in the case the actual quantity of any major item should become as much as 25% less than the estimated or contemplated quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a revised consideration upon the portion of the work above or below 25% of the estimated quantity. A "Major Item" shall be construed to be an individual bid item incurred in the proposal that has a total cost equal to or greater then five (5) percent of the total contract cost, computed on the basis of the proposal quantities and the contract unit prices. Any revised consideration is to be determined by agreement, between the parties otherwise by the terms of this Agreement, as provided under"Extra Work"Article G.4.5. G.8.3. Partial Payment: On or before the 1St day of each month the Contractor shall submit a Pay Request showing as completely as practicable the total value to the work done by the Contractor up to and including the 25th day of the preceding month; said Pay Request shall also include the value of all sound materials delivered on the site of the work that are to be fabricated into the work, providing the Contractor can produce a paid receipt for the materials. G-24 The Town shall then pay the Contractor on or before the 30th day of the current month the total amount of the Pay Request, less five percent (5%) of the amount thereof for contracts with a total contract price of four hundred thousand ($400,000.00) dollars or more, less ten percent (10%) for contracts with a total contract price of less than four hundred thousand ($400,000.00) dollars but greater than or equal to ten thousand ($10,000.00) dollars, and in contracts for less than ten thousand ($10,000.00) dollars the retainage shall be fifteen percent (15°1x), which five percent (5%), ten percent (10%) or fifteen percent (15%) shall be retained until final payment, and further less all previous payments and all further sums that may be retained by the Town under the terms of this Agreement. It is understood, however, that in case the whole work be near to completion and some unexpected and unusual delay occurs due to no fault or neglect on the part of the Contractor, the Town may, upon written recommendation of the Engineer, pay a reasonable and equitable portion of the retained percentage to the Contractor; or the Contractor at the Town's option, may be relieved of the obligation for fully completing the work, and thereupon, the Contractor shall receive payment of the balance due him under the work contract subject only to the conditions stated under"Final Payment." G.8.4. Final Completion and Acceptance: Within five (5) days after the Contractor has given the Engineer written notice that the work has been completed, or substantially completed, the Engineer and the Town shall inspect the work and within said time, if the work be found to be completed or substantially completed in accordance with the Contract Documents, the Engineer shall issue to the Town and the Contractor his Certificate of Completion, and thereupon it shall be the duty of the Town within ten (10) days to issue a Certificate of Acceptance of the work to the Contractor. G.8.5. Final Payment: Upon the issuance of the Certification of Completion, the Engineer, shall proceed to make final measurements and prepare final statement of the value of all work performed and materials furnished under the terms of the Agreement and shall certify same to the Town, who shall pay to the Contractor within thirty (30) days after the date of the Certificate of Completion, the balance due the Contractor under the terms of this Agreement, provided he has fully performed contractual obligations under the terms of this contract; and said payment shall become due in any event upon said performance by the Contractor. Neither the Certificate of Acceptance nor the final payment, nor any provisions in the Contract Documents, shall relieve the Contractor of the obligation for the fulfillment of any warranty, which may be required in the Special Conditions of the specifications. G.8.6. Payments Withheld: The Town may, on account of subsequently discovered evidence, withhold or nullify the whole or part of any certificate to such extent as may be necessary to protect himself from loss on account of: (a) Defective work not remedied (b) Claims filed or reasonable evidence indicating probable filing of claims (c) Failure of the Contractor to make payments properly to subcontractors or for material or labor (d) Damage to another contractor G-25 When the above grounds are removed or the Contractor provides a Surety Bond satisfactorily to the Town, which will protect the Town in the amount withheld, payment shall be made for amount withheld because of them. G.8.7. Delayed Payments: Should the Town fail to make payment to the Contractor of the sum named in any partial or final statement when payment is due, or should the Engineer fail to issue any statement on or before the date above provided, then the Town shall pay to the Contractor, in addition to the sum shown as due by such statement, interest thereon at the rate of six percent (6%) per annum, unless otherwise specified, from date due until fully paid, which shall fully liquidate any injury to the Contractor growing out of such delay in payment not promptly made, as provided under "Partial Payment," and any time thereafter treat the contract as abandoned by the Town and recover compensation, unless such payments were withheld in accordance with the provisions of"Payments Withheld." G.8.8. Time Filing Claims: It is further agreed by both parties hereto that all questions of dispute or adjustment presented by the Contractor shall be in writing and filed with the Engineer within thirty (30) days after the Engineer has given any directions, orders or instructions to which the Contractor so desires to take exception. The Engineer shall reply to such written exceptions by the Contractor and render his final decision in writing. It is further agreed that final acceptance of the work by the Town and the acceptance by the Contractor of the final payment shall be a bar of any claims by either party, except, where noted otherwise in the Contract Documents.

The tank will be added to the east side of the existing tank and pump station site. The site is located on the east side of 1900 U.S. Highway 377 in Westlake, as shown on the site plan attached herein. The ground surface is relatively flat in the area of the proposed tank with ground elevations for the borings ranging from 668.9 to 669.5. These elevations were provided by Graham Associates, Inc. The finish floor grade for the existing storage tank is Elev. 671.5 and we understand the finish floor grade for the new tank may be Elev. 671.5 or the finish floor elevation for the new tank may be less than 671.5, since the ground surface is lower in this area. The proposed tank will be approximately 125 feet in diameter and about 19 feet(±) high. We understand the tank will be steel. It is anticipated the tank will be supported by a ring footing with the interior of the ring filled with a granular material such as flexible base. 1.2 Purpose and Scope The purpose of this geotechnical engineering study has been to determine the general subsurface conditions, evaluate the engineering characteristics of the subsurface materials encountered, and develop recommendations for the proposed structures and related site features proposed for the project. To accomplish its intended purposes, the study has been conducted in the following phases: (1) drilling sample borings to determine the general subsurface conditions and to obtain samples for testing; (2) performing laboratory tests on appropriate samples to determine pertinent engineering properties of the subsurface materials; and, (3) performing engineering analyses, using the field and laboratory data to develop geotechnical recommendations for the proposed construction. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 1 FIELD EXPLORATION AND LABORATORY TESTING I 2.1 Field Exploration Subsurface materials at the project site were explored by four (4) borings drilled to a depth of approximately 25 feet in the proposed storage tank area. Borings were made with a truck mounted CME 75 drill rig using continuous flight augers on December 17, 2012. Boring locations were staked by Graham Associates, Inc. and are shown on the Plan of Borings in Appendix A. Graham Associates also provided ground elevations and coordinates for each of the borings. The boring logs and a key to terms and descriptions on the logs are provided in Appendix A. Relatively undisturbed samples of cohesive soils encountered in the borings were taken using a thin wall Shelby tube sampler. Depths at which these samples were taken designated "U" are indicated in the"Sample" column of the boring logs. Estimates of the consistency of the cohesive soil samples were obtained in the field using a hand penetrometer. The result of a hand penetrometer reading is recorded at a corresponding depth in the "Penetrometer, TSF" column of the boring logs. When the capacity of the hand penetrometer is exceeded, the value of 4.5+ is recorded. Limestone and shale, encountered below the clay soils, were evaluated in place by the Texas Department of Transportation (TxDOT) "Texas Cone Penetrometer' (TCP) test. Either the number of blows required to produce 12 inches of penetration, or the inches of penetration due to 100 blows of the hammer are noted on the boring log designated "T" in the"Penetration Resistance"column. Soil descriptions on the boring logs are a compilation of field logging and review of samples in the soils laboratory by the geotechnical engineer. The stratification lines represent the approximate boundary between soil types and the transition can be gradual. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 2 Periodic observations were made in the borings to observe for shallow subsurface seepage. Water level readings made after completion of the borings are noted on the respective logs. Water levels measurements refer only to those observed at the times and places indicated, and can vary with time, geologic condition, construction activity, rainfall and other factors. 2.2 Laboratory Testing Representative samples of the soils were tested in the geotechnical soils laboratory. Liquid limit and plastic limit tests (Atterberg limits) and percent passing the #200 mesh sieve were performed on soil samples from the borings in order to classify them according to the Unified Soil Classification (USC) System. Results of the soil classification, minus #200 sieve, moisture content and density tests are presented on each respective boring log. A summary is provided in Appendix B. Strength properties of the soil were evaluated by performing unconfined compression tests. The results of these tests are reported as Qu values (in tons per square foot). Moisture and density determinations were also made on samples to determine the in situ conditions. These tests are included on the boring logs. Swell tests were performed on representative samples of the anticipated suhOrade soils. Test results are provided in Appendix B. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 3 3 SUBSURFACE CONDITIONS 3.1 Subsurface Stratification Specific types and depths of subsurface strata encountered in the borings are shown on the attached boring logs. The general subsurface conditions encountered in the borings consist of the following: The borings encountered approximately one and one-half (1.5) feet of soft to stiff dark brown and tan clay FILL material with some limestone fragments. The fill material is underlain by stiff to very stiff dark brown and brown clay with calcareous nodules to depths of approximately 4 to 6 feet. The clays classify as "CH" soils based on the USC System. The clays are anticipated to be corrosive. Below depths of approximately 4 to 6 feet the soils consist of soft to stiff yellowish tan lean clay with some gray color. These materials also contain calcareous nodules and calcareous material, sand seams and layers. Below depths of approximately 8 to 9 feet the clays have increasing amounts of coarse sand and fine gravel seams and perched water seepage was encountered in these granular seams.The clays continued to depths of approximately 12 to 14 feet below existing grade. In general the yellowish tan lean clay classifies as"CU, however it is borderline on "CH"within some layers. Below depths of approximately 12 to 14 feet tan weathered limestone (ROCK)with some clay seams and layers was encountered and continued to depths of approximately 16 to 17 feet where gray limestone (ROCK) with some shale seams and layers was encountered. Below depths of approximately 23 to 24 feet, gray to dark gray shale was encountered and continued to the completion depths of the borings at approximately 25 feet below existing grade. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 4 The general subsurface conditions and material properties are summarized in the following Table. Tete - General Summary of Subsurface Soil Conditions Stratum Approx.Thickness and General Description of Material General No. (Approx.

Hardness terms for soil and rock are for relative comparison of the various samples, and are not intended to be used as an indication of the ease or difficulty of excavation or excavation stability. Hardness terms on the logs may be based upon a combination of the test and observation methods listed in the general notes, and upon field observations. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 5 Swell tests performed on representative samples of the clay indicates swell values ranging from 0.1 to 1.7 percent. 3.2 Shallow Subsurface Seepage Observations Brief observations were conducted for subsurface seepage water during and immediately after the drilling operations. Shallow seepage was observed at depths of approximately 8 to 9 feet below existing grade in the borings as they were drilled. Subsequent water level readings in the borings shortly after drilling (approximately 30 to 45 minutes after drilling) indicate water levels approximately 5 to 6 feet below existing grade. Table 3-2 Shallow Subsurface Seepage Observations Boring Approximate Depth.to Approximate Depth of No. Seepage Observed Shallow Perched Water During Drilling 30 to 45 Minutes after Drilling B-1 9 ft. 5.5 ft. B-2 8 ft. 5.6 ft. B-3 9 ft. 5.0 ft. B-4 : 9ft 5.0 ft. Shallow subsurface seepage can occur due to seasonal variations in the amount of rainfall; site topography and runoff, hydraulic conductivity of soil strata; and other factors not evident at the time the borings were performed. Water traveling through the soil (subsurface water) is often unpredictable. This could be due to seasonal changes in shallow subsurface water and due to the unpredictable nature of subsurface seepage paths. Therefore, it is necessary during construction for the contractor to be observant for shallow subsurface seepage in excavations in order to assess the situation and make necessary changes and/or recommendations. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 6 3.3 Area Geology Based on the soil sample borings, site observations made by the author and available geological maps, the site lies within the Grayson Formation. Additionally, the upper soils appear to be alluvial soils possibly related to an old drainage area passing through this site in past geological time. The alluvial deposits typically consist of clays, sands, silty and clayey sands, sand and gravel, and a combination of these. In full section, the Grayson Formation is approximately fifty (50)feet thick and dips to the Southeast at approximately two (2) degrees. Clays, marls, and limestone's compose the Grayson Formation. The clays and marls vary from light brown to gray and contain considerable amounts of gypsum and pyrite. Layers of limestone are thin, normally less than one (1) foot in thickness, and occur in the middle to upper portion of the formation. The residual soils of the Grayson Formation are usually deep and highly active. 3.4 Expansive Soil Movements The clay soils encountered at this site can undergo shrink and swell as the soil moisture content fluctuates during seasonal wet and dry cycles. An estimate of the soil movement for this site has been made using the Texas Department of Transportation (TxDOT) procedure TEX-124-E for determining Potential Vertical Rise (PVR), a swell test and engineering judgment and experience based on previous geotechnical studies on sites with similar soil conditions. Soil movements ranging from approximately 1.5 to 3 inches have been estimated, as the soils undergo moisture changes. The estimated soil movements are based on the subsurface conditions revealed by the borings and for seasonal moisture fluctuations. Soil movements, significantly larger than estimated, could occur due to inadequate site grading, poor surface drainage and/or ponding of rainfall. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 7 3.5 Seismic Site Classification The site has been classified with respect to seismic design criteria contained in the 2006 International Building Code (IBC), Section 1613.5.21. The criteria require characterization of the upper 100 feet of subsurface materials. Based on the IBC criteria, the site is generally classified as Site Class "C" as per Table 1613.5.2. Note the IBC requires a site soil profile determination extending a depth of 100 feet for seismic site classification. However, our scope of services did not include a boring to 100 feet. The deepest boring extended to 25 feet, and it can only be estimated that the Grayson Formation and underlying consolidated geological formations continue to a depth of 100 feet or more.

LANDTEC ENGINEERS 1832 water tank-westiake-dec2012.doc 8 4 ANALYSIS AND RECOMMENDATIONS 4.1 General We understand the proposed one million gallon steel tank will be supported on a ring foundation similar to the existing water tank which is immediately to the west of the proposed tank. Geotechnical design data for a ring footing is provided in this report along with recommendations for subgrade preparation and material type for support of the new tank. 4.2 Foundation and Subgrade Recommendations If the finish floor elevation for the tank will be Elev. 671.5 ft. (same as the existing tank) the following recommendations apply. ® The existing grade within the area of the tank is Elev. 669 to 669.5, based on the ground shots taken at the time the borings were made on December 17, 2012. This will require approximately 2 to 2.5 feet of fill material to raise the grade to Elev. 671.5 not counting the need to over excavate the existing soils. Therefore, prior to raising the grade, several feet of the existing clay soils will need to be over-excavated. ® We recommend over-excavating to Elev. 667.0 which is approximately 2 to 2.5 feet below existing grade. Additionally, the soils should be excavated a minimum of 5 feet beyond the tank perimeter. Following the over-excavation process, the subgrade should be observed by the geotechnical engineer to determine if additional excavation will be required. If the subgrade soils are suitable, the subgrade should be proof-rolled and compacted to a minimum of 95% of Standard Proctor density at a moisture content ranging from optimum to four percentage points above optimum (0 to +4). ® In some locations within the tank footprint the soils could be wet due to the irrigation system leak and/or poor surface drainage. If soft wet soils are encountered they should be undercut and replaced with flexible base material. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 9 ® Once the subgrade is observed, compacted and tested, approximately 4.5 feet of fill will have to be added to achieve Elev. 671.5. ® The fill should consist of crushed limestone flexible base material or crushed concrete flexible base material meeting the same specifications. A minimum of one (1) foot of flexible base material should be placed below the ring footing and also the one (1) foot of flexible base should extend a minimum of 5 feet beyond the outside edge of the ring footing. • The flexible base material should conform to TxDOT Item 247 Type A, Grade 1 Flexible Base. The flexible base should be compacted in maximum of 8-inch thick lifts to a minimum of 98 percent of Standard Proctor, ASTM D698, to a moisture content ranging from one percentage point below optimum moisture to four percentage points above optimum moisture (-1 to +4). If the Finish Floor (FF) elevation of the new tank will be less than Elev. 671.5, for each increment the finish floor grade is lowered, the same amount of over-excavation should be made. However, the over-excavation should not exceed about three and one-half feet below the existing grade. Example and to recap, if the FF is 671.5 ft. then over- excavate to 667 ft. as described in prior paragraphs. If the FF is lowered by one foot, then over-excavate one additional foot, taking care to not go too deep because of the need to stay above the potential perched water seepage zone. Once the Finish Floor elevation is determined, Graham Associates and LandTec should discuss final pad preparation below the tank with respect to the foundation and over-excavation recommendations, and, to verify they are appropriate for the project. For a ring wall footing bearing within the compacted and tested flexible base at a depth recommended herein, an allowable bearing pressure of 2,500 pounds per square foot can be used to size the footing. This bearing value includes a safety factor of three. The bottom of the footing should be at least three feet below the lowest adjacent outside grade. The dimensions of the ring footing are determined by the structural engineer. To limit differential movement between the center and the edge of the tank, we recommend LANDTeC ENGINEERS 1832 water tank-westlake-dec2012.doc 10 selecting the ring wall dimensions such that the footing contact pressure is about equal to the pressure under the tank. Footing excavations should be observed to determine that all excessively loose, soft, or otherwise undesirable materials are removed and that foundations will bear on satisfactory material. Soil exposed in the bases of all satisfactory footing excavations should be protected against detrimental change in condition such as from disturbance, rain, or excessive drying. Surface runoff should be drained away from the excavations and not allowed to pond. The onsite clay soils can be used to backfill outside the ring wall foundation. The surface of the backfill material should slope at 1.5 to 3 percent back to natural grade. Good drainage should be provided such that surface water does not pond after rainfall. The fill should be placed in maximum of 8-inch thick lifts and be compacted to a minimum of 95% of Standard Proctor ASTM D698 to a moisture content ranging from plus two to plus five percentage points of optimum moisture (+2 to +5). Recommendations concerning general site filling are given in the Earthwork Section. Hand operated tampers (sleds or jumping jacks) or other lightweight compactors are preferred in small areas adjacent to walls or footings. Consideration was given to the use of non-expansive, select fill material (clayey sands and sandy lean clays with PI between 6 and 15) below the tank and used in conjunction with the flexible base material as previously used for the existing tank. However, we do not recommend placing the sandy select fill soils into the over-excavation and then topping out with flexible base material. Since both materials generally cost about the same and since flexible base materials are readily available, we recommend the over- excavation be entirely filled with flexible base and continue to add the flex base to the desired FF grade for the tank. 4.3 Thrust Blocks Thrust blocks for pipe should be proportioned to exert a maximum lateral pressure of 250 pounds per square foot per foot of depth. The depth should be taken from final grade to the center of the thrust block. If friction along the bottom of the block is used in design, a coefficient of friction of 0.35 is recommended. These design parameters are LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 1 7 based on the thrust blocks being poured adjacent to undisturbed stiff clay, or compacted, tested, and accepted fill. 4.4 Secondary Considerations To reduce the potential for moisture induced soil movement (uplift) as well as shrinkage, it is very important that measures be taken to control moisture changes around and below the structure. The following recommendations/comments should be incorporated into the overall project design. 1. Site grading should be designed to provide surface drainage so that water does not pond during or after construction. A slope of 1.5 to 3 percent should be provided, such that the ground surface slopes away from the ring foundation 10 to 15 feet. The building pad should be higher that the outside surrounding ground surface. Low areas should be drained and/or sloped to drain so that water (irrigation or storm water) do not pond. Ponding water can cause sidewalks, entries, and any other type of flatwork to undergo differential movement, usually upward. 2. Utility ditches should be backfilled so that they do not become conduits that allow surface water to flow adjacent to or below the foundation. This can be accomplished by the use of clay or concrete plugs placed within the trench backfill. 3. Landscape irrigation systems should be designed and located to prevent excessive moisture adjacent to the foundation. Systems should not be located where water will be sprayed onto building walls and subsequently drain downward and flow into the soils beneath foundations. 4. Utilities which project through floor slabs, particularly where expansive soils or soils subject to settlement are present, should be designed with some degree of flexibility and/or with a sleeve to reduce the potential for damage to the utilities should movement occur. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 12 5 EARTHWORK 5.1 Site Preparation The following recommendations apply to general earthwork at the site. The building site should be stripped of vegetation, roots, debris, and other organic material. It is estimated that the depth of stripping will be on the order of 6 inches. The actual stripping depth should be based on field observations with particular attention given to old drainage areas, uneven topography, and excessively wet soils. The stripped areas should be observed to determine if additional excavation is required to remove weak or otherwise objectionable materials that would adversely affect the fill placement. The subgrade should be firm and able to support the construction equipment without displacement. Soft or yielding subgrade should be corrected and made stable before construction proceeds. The subgrade should be proof rolled to detect soft spots, which if exist, should be reworked. Proof rolling should be performed using a heavy pneumatic tired roller, loaded dump truck, or similar piece of equipment weighting at least 25 tons. The proof rolling operations should be observed by the project geotechnical engineer or his representative. Prior to fill placement, the subgrade should be scarified to a depth of approximately six (6) inches, its moisture content adjusted, and recompacted to the density specified herein for fill. If any soil is brought onto the jobsite from outside sources and used as fill material, the soil should generally classify "CL" soils based on the Unified Soil Classification (USC) System. For "CL" type soils the Liquid Limit should be less than 45 and the Plasticity Index less than 25. 5.2 Placement and Compaction Fill material should be placed in loose lifts not exceeding eight (8) inches in uncompacted thickness. The fill material should be uniform with respect to material type and moisture content. Clods and chunks of material should be broken and the fill material mixed by disking, blading, or plowing, as necessary, so that a material of uniform moisture and density is obtained for each lift. Water required for sprinkling to bring the fill material to the proper moisture content should be applied evenly through each layer. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 13 The fill material should be compacted to a minimum of ninety-five (95) percent of the maximum dry density determined by the Standard Proctor test, ASTM D 698. In conjunction with the compacting operation, the fill material should be brought to the proper moisture content. For on-site soils the moisture content should range from optimum to four percentage points above optimum (0 to +4). The ranges in moisture content given herein are provided as recommended ranges. For some soils and under some conditions, the earthwork contractor may have to maintain a more narrow range of moisture content (within the recommended range) in order to consistently achieve the recommended density. Field density tests should be taken as each lift of fill material is placed. As a guide, one field density test per lift for each 5,000 square feet of compacted area is recommended. A minimum of two tests per lift should be required. The earthwork operations should be observed and tested on a continuing basis by an experienced engineering technician working in conjunction with the project geotechnical engineer. Each lift should be compacted, tested, and approved before another lift is added. The purpose of the field density tests is to provide some indication that uniform and adequate compaction is being obtained. The actual quality of the fill, as compacted, should be the responsibility of the contractor and satisfactory results from the tests should not be considered as a guarantee of the quality of the contractor's filling operations. Trench backfill for utilities should be properly placed and compacted. Dense or dry backfill can swell and create a mound along the ditch line. Loose or wet backfill can settle and form a depression along the ditch line. Distress to overlying structures, pavements, sidewalks, etc. can occur if heaving or settling happens. A granular bedding material is recommended for pipe bedding. Clean coarse sand or well graded crushed rock make good bedding materials. Care should be taken to prevent the backfilled trench from becoming a French Drain and piping surface or subsurface water beneath structures or pavements. The use of concrete cut-off collars or clay plugs may be required to prevent this from occurring. Trench backfill should be placed and compacted in uniform lifts of 8 to 12 inches and be tested for moisture and density. We recommend that each lift be tested with spacing of LANDTEC ENGINEERS 1832 water tank-westiake-dec2012.doc 14 100 feet along the trench. Compaction should be to a minimum of 95 percent of Standard Proctor density (ASTM D698) at a moisture content ranging from one percentage point below optimum to four percentage points above optimum (-1 to +4). Fill or cut slopes constructed in the soils at the site should be maintained on slopes no steeper than 4 horizontal to 1 vertical (4HA V). All slopes, whether temporary construction slopes or permanent fill slopes should be designed to allow drainage at planned areas where erosion protection can be provided, instead of allowing surface water to flow down unprotected slopes. Vegetative ground cover should be provided as soon as practical to completed slopes. 5.3 Non-Expansive, Select Fill If non-expansive, select fill material is needed on the project it should be a clayey sand or lean sandy clay with a liquid limit (LL) less than thirty five (35), and a plasticity index (PI) between six (6) and fifteen (15). The select fill should be placed in loose lifts not exceeding eight (8) inches in un-compacted thickness, and be uniformly compacted to a minimum of ninety-five (95) percent of the maximum dry density determined by Standard Proctor (ASTM D 698). The moisture content of the fill at the time of compaction should be from optimum to plus five (5) percentage points of optimum (0 to +5). The moisture content and density of the in-place select fill should be maintained from the time the pad is completed until placement of the slab. Prior to placement of the select fill, the upper six (6) inches of the subgrade should be scarified and recompacted to the density and moisture requirements previously given. The select fill should be placed as soon as possible after preparation of the subgrade soils. 5.4 Acceptance of Imported Fill The owner must approve any soil hauled onto this project from off-site sources. The contractor must obtain a written, notarized certification from the landowner of each proposed off-site soil borrow source stating that to the best of the landowner's knowledge and belief there has never been contamination of the borrow source site with hazardous or toxic materials. The certification must be furnished to the owner prior to LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 15 proceeding to furnish soils to the site. Soil materials derived from the excavation of underground petroleum storage tanks shall not be used as fill on this project. 5.5 Excavations Excavations should consider the stability of adjacent structures, pavement, underground utilities, utility poles, etc. Unstable soils include, but are not necessarily limited to, (1) jointed, fissured, and slickensided materials (2) soils with pockets or layers of sand or gravel, and (3) soils with groundwater seepage occurring. Slopes in these types of soils may become unstable during periods of wet weather or as loads are applied to the top and/or along the slope. The stability is also affected by weather conditions, excavation depth, adjacent structures, construction equipment, and the length of time the excavation will remain open. Surcharge loads, either static or dynamic, should not be applied to the slope, particularly at the top of slope. Construction equipment should be prevented from traveling along or near the top of the excavation slope. (Monitoring of temporary slopes, trenches, and dewatering during construction should be undertaken by the contractor to detect early warnings of movement within slopes, structures, pavements, etc. In all cases, the requirements of the Occupational Safety and Health Administration (OSHA) must be followed. It is important for the contractor to monitor the slope stability by observation and measurement, and to prevent excessive loads (especially heavy vibratory loads) from being applied to the slope. The contractor should be responsible for maintaining the slopes in a safe condition during construction and the use of slope stability monitoring equipment is recommended. Inclinometers are one means of measuring slope movement. This report has not been prepared for trench safety design and slope angle design. In the Federal Register, Volume 54, No. 209 (October 1989), the United States Department of Labor, Occupational Safety and Health Administration (OSHA) amended its "Construction Standards for Excavations, 29 CFR, part 1926, Subpart P". This document was issued to better insure the safety of workmen entering trenches or excavations. It is mandated by this federal regulation that excavations, whether they be LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 16 utility trenches, basement excavation or footing excavations, be constructed in accordance with the new OSHA guidelines. It is our understanding that these regulations are being strictly enforced and if they are not closely followed, the owner and the contractor could be liable for substantial penalties. The contractor is solely responsible for designing and constructing stable, temporary excavations and should shore, slope, or bench the sides of the excavations as required to maintain stability of both the excavation sides and bottom. The contractor's "responsible person", as defined in 29 CFR Part 1926, should evaluate the soil exposed in the excavations as part of the contractor's safety procedures. In no case should slope height, slope inclination, or excavation depth, including utility trench excavation depth, exceed those specified in local, state, and federal safety regulations. We are providing this information solely as a service to our client. LandTec Engineers does not assume responsibility for construction site safety or the contractor's or other parties' compliance with the local, state, and federal safety or other regulations. LANDTEC ENGINEERS 1832 water tank-westlake-dec2412.doc 17 6 PAVEMENT 6.1 General Information Subgrade materials at this site are anticipated to consist of moderate to high plasticity clays soils. The clays loose strength and support capability with an increase in moisture content which is common below paving. Lime treatment of the clay soil is typically used below asphalt paving in order to increase the strength and support characteristics of the subgrade. Often, the lime treated subgrade is omitted below reinforced concrete paving, with the concrete pavement placed directly on a well compacted and tested subgrade. It is anticipated the new section of concrete drive serving the new water storage tank will be a small section extending from the existing concrete drive. Since the pavement section will be small, the use of lime treatment of the subgrade can be replaced with 6- inches of flexible base material that is compacted and tested. Since the area is low and has been wet with standing water, a minimum 6-inch section of flexible base material should be used to support the concrete paving. Flexible base should conform to TxDOT Item 247, Type A, Grade 1 and be compacted to a minimum of 95% of Standard Proctor, ASTM D698 at a moisture content ranging from minus one to plus three(-1 to+3) percentage points of optimum moisture. The subgrade below the flexible base should be compacted to a minimum of 95 percent of Standard Proctor(ASTM D 698) at a moisture content ranging from minus one to plus three(-1 to+3) percentage points of optimum moisture. The moisture content and density of the completed base section must be maintained until the paving is complete. The base should be graded to prevent ponding and infiltration of excessive moisture on or adjacent to the pavement. Since the soils at this site consist of expansive clays, some movements within the pavement section should be expected. Proper drainage should be provided both during and after construction, and a minimum slope of one (1) percent is recommended for the paved areas. Particular emphasis should be given to areas where the pavement is placed directly adjacent to entries. If the subgrade heaves, the pavement could end up LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 18 sloping in the wrong direction, causing problems with drainage. The pavement should be maintained properly, including the use of a flexible joint material to seal cracks which can occur during the life of the pavement. A proper testing and inspection program during construction is also vital to the overall long-term performance of the pavement. 6.2 Pavement Section The following pavement section is given for preliminary information at this time. When the site grading plan is completed, this information should be reviewed. Table 6-1 Pavement Section for Service Drive Pavement Section Jointed Reinforced Subgrade Type Concrete Pavement Thickness 6 inches of flexible Access Drives 7 inches(minimum) base on compacted and tested subgrade Notes: (1) The minimum pavement thickness recommended is 7-inch due to industrial type use of paving including occasional loaded trucks and service vehicles. The concrete should have a minimum compressive strength of 3,500 psi at 28-days. Proper finishing of concrete pavement requires the use of sawed and sealed joints. Sawing of joints should begin as soon as the concrete has hardened sufficiently to permit sawing without excessive raveling. All joints should be completed before uncontrolled shrinkage cracking occurs. Joints should be cleaned and sealed before opening to the traffic. Recommended joint spacing should incorporate the information provided in "Joint Design for Concrete Highway and Street Pavements" published by the Portland Cement Association. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 19 7 GENERALC T In any geotechnical study, the design recommendations are based on a limited amount of information about the subsurface conditions. In the analysis, the geotechnical engineer must assume the subsurface conditions are similar to the conditions encountered in the boring. However, during construction, anomalies in the subsurface conditions are quite often revealed. Therefore, it is recommended that the project geotechnical engineer be retained to observe-earthwork and foundation installation and perform materials evaluation during the construction phase of the project. This enables the project geotechnical engineer to stay abreast with the project and to be readily available to evaluate unanticipated conditions, to conduct additional tests if required and, when necessary, to recommend alternative solutions to unanticipated conditions. It is proposed that construction observation commence at the outset of the project. Experience has shown that the most suitable method for procuring these services is for the owner to contract directly with the geotechnical / materials engineer. This results in a clear, direct line of communication between the owner or his representative and the geotechnical/materials engineer. The services described in this report were performed consistent with generally accepted geotechnical engineering principles and practices. No other warranty, expressed or implied, is made. These services were performed in agreement with our client. This report is solely for the use and information of our client unless otherwise noted. Any reliance on this report by a third party is at such party's sole risk. Opinions and recommendations contained in this report apply to conditions existing when services were performed and are intended only for the client, purposes, locations, time frames, and project parameters indicated. We do not warrant the accuracy of information supplied by others, or the use of segregated portions of this report. LANDTEC ENGINEERS 1832 water tank-westlake-dec2012.doc 20 The conclusions and recommendations in this report are invalid if: ® the design loads change; • the structure is relocated; ® the report is used for adjacent or other property or buildings; ® grades, ground-water levels, or both, change between the issuance of this report and construction; ® any other change is implemented that materially alters the project from that proposed when this report was prepared The boring log does not provide a warranty of the conditions that may exist at the entire site. The extent and nature of subsurface soil and ground-water variations may not become evident until construction begins. Variations in soil conditions between borings could possibly exist between or beyond the points of exploration or groundwater elevations may change, both of which may require additional studies, consultation, and possible design revisions. Any person associated with this project who observes conditions or features of the site or surrounding areas that are different from those described in this report should report the differences immediately for consideration and evaluation. This report was prepared solely for the use of our client and should be reviewed in its entirety. As referenced previously, it is recommended that Graham Associates and LandTec Engineers meet together and review those portions of the plans and specifications for this project that pertain to geotechnical recommendations contained in this report as a means to determine whether the recommendations have been interpreted as intended. This is typically done when the plans are at the 50 to 75 percent design level.

Fissured : Containing shrinkage cracks, frequently filled with fine sand or silt; usually more or less vertical. Laminated Composed of thin layers of varying color and texture. Interbedded : Composed of alternate layers of different soil types. Calcareous Containing appreciable quantities of calcium carbonate. Well graded Having wide range in grain sizes and substantial amounts of all intermediate particle sizes. Poorly graded Predominantly of one grain size, or having a range of sizes with some intermediate size missing. NOTE: Slickensided and fissured clays may have lower unconfined compressive strengths because of planes of weakness or cracks in the soil. The consistency rating of such soils are based on penetrometer readings. DEGREE OF WEATHERING: Unweathered Rock in its natural state before being exposed to atmospheric agents. Slightly Weathered Noted predominantly by color change with no disintegrated zones. Weathered Complete color change with zones of slightly decomposed rock. Severely Weathered : Complete color change with consistency,texture,and general appearance approaching soil. SUBSURFACE CONDITIONS: Soil and rock descriptions on the boring logs are a compilation of field data as well as from laboratory testing of samples. The stratification lines represent the approximate boundary between materials and the transition can be gradual. Water level observations have been made in the borings at the times indicated. It must be noted that fluctuations in the groundwater level may occur due to variations in rainfall, hydraulic conductivity of soil strata, construction activity,and other factors. Hardness terms for soil and rock are for relative comparison of the various samples, and are not intended to be used as an indication of the ease or difficulty of excavation or of excavation stability. Hardness terms on the logs may be based upon a combination of the test and observation methods listed above, and upon field observations.
