This law provides that, in order to be awarded a contract as low bidder, nonresident bidders (out-of-state contractors whose corporate offices or principal place of business are outside of the State of Texas) bid projects for construction, improvements, supplies or services in Texas at an amount lower than the lowest Texas resident bidder by the same amount that a Texas resident bidder would be required too underbid a nonresident bidder in order to obtain a comparable contract in the State in which the nonresident's principal place of business is located. The appropriate blanks in Section A must be filled out by all out-of-state or nonresident bidders in order for your bid to meet specifications. The failure of out-of-state or nonresident contractors to do so will automatically disqualify that bidder. Resident bidders must check the box in Section B. A. Nonresident vendors in (give State), our principal place of business, are required to be percent lower than resident bidders by State law. A copy of the Statute is attached. Nonresident vendors in (give State), our principal place of business, are not required to underbid resident bidders. ® Our principal place of business or corporate offices are in the State of Texas.

It is the intent of the City of Fort Worth to comply with the requirements of the Asbestos National Emissions Standards for Hazardous Air Pollutants (NESHAP) found at 40 CFR Part 61, Subpart M. This specification will establish procedures to be used by all Excavators in the removal and disposal of asbestos cement pipe (ACP) in compliance with NESHAP. Nothing in this specification shall be construed to void any provision of a contract or other law, ordinance, regulation or policy whose requirements are more stringent. B. ACP is defined under NESHAP as a Category II, non -friable material in its intact state but which may become friable upon removal, demolition and/or disposal. Consequently, if the removal/ disposal process renders the ACP friable, it is regulated under the disposal requirements of 40 CFR 61.150. A NESHAP notification must be filed with the Texas Department of Health. The notification must be filed at least ten days prior to removal of the material. If it remains in its non - friable state, as defined by the NESHAP, it can be disposed as a conventional construction waste. The Environmental Protection Agency (EPA) defines friable as material, when dry, which may be crumbled, pulverized or reduced to powder by hand pressures. C. The Generator of the hazardous material is responsible for the identification and proper handling, transportation, and disposal of the material. Therefore, it is the policy of the City of Fort Worth that the Excavator is the Generator regardless of whether the pipe is friable or not. D. It is the intent of the City of Fort Worth that all ACP shall be removed in such careful and prudent manner that it remains intact and does not become friable. The Excavator is responsible to employ those means, methods, techniques and sequences to ensure this result. A 02114107 SC-56 .. w PART D - SPECIAL CONDITIONS E. Compliance with all aspects of worker safety and health regulations including but not limited to the OSHA Asbestos Standard is the responsibility of the Excavator. The City of Fort Worth assumes no responsibility for compliance programs, which are the responsibility of the Excavator. (Copy of forms attached) F. The removal and disposal of ACP shall be subsidiary to the cost of installing the new pipe unless otherwise stated or indicated on the project plans or contract documents_ D-68 STORM WATER POLLUTION PREVENTION (FOR DISTURBED AREAS GREATER THAN 1 ACRE) PERMIT: As defined by Texas Commission on Environmental Quality (TCEQ) regulations, a Texas Pollutant Discharge Elimination System (TPDES) General Construction Permit is required for all construction activities that result in the disturbance of one to five acres (Small Construction Activity) or five or more acres of total land (Large Construction Activity).

Perform the boring from the low or downstream end unless specified otherwise. Bore the holes mechanically and use a pilot hole. By this method, an approximate 2" pilot hole shall be bored the entire length of the crossing and shall be checked for line and grade. This pilot hole shall serve as the centerline of the larger diameter hole to be bored. Place excavated material near the top of the working pit and dispose of material as required. The use of water or other fluids in connection with the boring operation will be permitted only to the extent to lubricate cuttings. Jetting shall not be permitted. b. In unconsolidated soil formations, a gel -forming colloidal drilling fluid consisting of at least 10% of high grade carefully processed bentonite may be used to consolidate cuttings of the bit, seal the walls of the hole, and furnish lubrication for subsequent removal of cuttings and installation of the 16 pipe immediately thereafter. C. In locations where the soil formation is other than consolidated rock, insert the casing pipe simultaneously with the boring operation. This requirement applies to all bored holes of 18" or greater in diameter. For smaller diameter bored holes, it is desirable that the casing be installed as the boring progresses, but because of differences in soil formations, the time for inserting the casing shall be the Contractor's responsibility. In the event that caving sand or water bearing materials are encountered, insert the casing pipe simultaneously with the boring operation regardless of the diameter of the bored hole. In all cases, the security and integrity of the roadway is the primary concern.

Set the pipe to be jacked on guides, properly braced together, to support the section of the pipe and to direct it in the proper line and grade. Place the whole jacking assembly so as to line up with the direction and grade of the pipe. In general, excavate embankment material just ahead of the pipe and material removed through the pipe. Force the pipe through the embankment with jacks into the space provided. b. The excavation for the underside of the pipe, for at least 1/3 of the circumference of the pipe, shall conform to the contour and grade of the pipe. Provide a clearance of not more than 2" for the upper half of the pipe. This clearance shall be tapered off to zero at the point where the excavation conforms to the contour of the pipe. Extend the distance of the excavation beyond the end of the pipe depending on the character of the material, but do not exceed 2' in any case. Decrease the distance if the 11102104 ASC - 77 4- va 4W a wr W W 40 O. wr PART DA - ADDITIONAL SPECIAL CONDITIONS qmw .m C. .. character of the material being excavated makes it desirable to keep the advance excavation closer to the end of the pipe. If desired, use a cutting edge of steel plate around the head end of the pipe extending a short distance beyond the end of the pipe with inside angles or lugs to keep the cutting edge from slipping back onto pipe. d. When jacking of pipe has begun, cant' on the operation without interruption to prevent the pipe from becoming firmly set in the embankment. Remove and replace any pipe damaged in the jacking operations. The Contractor shall absorb the entire expense. 5. CROSSINGS INSTALLED WITH TUNNEL LINER PLATE a.

The tunnel shall be isolated from the bore pit at the end of the day. 3) The Contractor shall start grouting the voids space from the middle outward. .. 4) Sound encasement pipe to determine location of void spaces. Perform sounding as a baseline for future testing. Sounding shall be done prior to grout installation. Record results at least at intervals of 25'. 5) Grout fill the annular space until grout comes out the next insertion point. Cap the hole when grout continuously flows out. The cap must be screwed or fastened into the encasement pipe. The cap shall be able to make a watertight seal and handle external loads. Continue capping the holes until grout does not continue to flow to — the next hole. If the flow does not flow through the hole, sound pipe and insert the grout in the next hole or create a new insertion point as necessary. During the process, record the insertion points and keep a log of the volume of grout inserted into the void space. Tests shall be performed at a minimum 10 foot interval around the circumference. '-' b. Between encasement pipe and carrier pipe 1) The contractor shall use 3" PVC pipe to convey grout through the ,- bore pit and proposed tunnel to predetermined discharge points. One deliver point site will be required near each end of the tunnel. 11102104 ASC - 100 PART DA - ADDITIONAL SPECIAL CONDITIONS The Contractor shall connect PVC pipe to selected insert point.

If the edge of existing concrete pavement is damaged during the construction of adjacent pavement; the damaged panel(s) must be removed and replaced in its entirety by the Contractor at his own expense. 5. APPLICATION AND FINAL DETERMINATION OF POLICY It is not the intention of this policy that the Contractor is required to remove and replace at his own expense any concrete that cracks due solely to causes other than his own materials and/or workmanship. It is possible that a structural crack or cracks have been caused by a combination of factors. It is the policy that if a deficiency of materials and/or workmanship is found to be a contributing cause, then the contractor shall remove and replace the panels that contain the crack or cracks at no expense to the City. If cracks exist in the project, the City Engineer or his/her designee will make the determination if the crack is minor or structural which determination shall be final. If the crack is structural, the Contractor and the City will attempt to agree on the cause or causes of the crack. If the Contractor and City agree that the cause of a structural crack requiring removal and replacement is at least in part due to Contractor's deficient material or workmanship, the concrete pavement will be removed and replaced at Contractor's entire expense. If the Contractor and City cannot agree as to the cause of a structural crack, the City may hire an independent geotechnical engineer to perform testing and analysis to determine the cause of the crack. The contractor will escrow 50% of the proposed costs of the geotechnical contract with the City. If the City's hired geotechnical engineer determines that the cause of a structural crack is at least in part due to Contractor's deficient material or workmanship, the concrete pavement will be removed and replaced at Contractor's entire expense and the Contractor will also pay the City for the entire cost of the geotechnical investigation. If the City's hired geotechnical engineer fails to determine that the cause of the structural crack is due to Contractor's deficient material or workmanship, the concrete pavement will not be removed and replaced without additional compensation to the Contractor. In turn, the Contractor's escrowed funds, as described above, will be released. Rev 06-10-09 SP-38 76.

This report describes the subsurface conditions encountered in the borings, and provides pavement recommendations to meet the City of Fort Worth design standards. Our scope of services included drilling and sampling eight borings, laboratory testing, and engineering analyses. PROJECT DESCRIPTION The planned roadway consists of a section of Edwards Ranch Road south of Southwest Parkway 121 and a section of Clearfork Main Street to the intersection before the bridge_ at the Trinity River in Fort Worth, Texas. The section of Edwards Ranch Road will be about 1,600 feet long. Cuts and fills for this section are anticipated to be up to 7 and 2 feet, respectively. The Clearfork section will be about 2,300 feet. Cuts and fills for this section are anticipated to be up to 3 feet. No retaining walls: are planned for the roadway. These roadways will be considered Collector streets by the City of Fort Worth, and will be designed by Fort Worth Standards. SITE EXPLORATION PROCEDURES Field Exploration Eight borings were drilled on September 26, 2008 at the locations shown on the Boring Location Diagram, Figure 1, in the Appendix. The test locations were established in the field by a representative of Terracon using measurements from available reference features and estimating right angles. The boring locations should be considered accurate only to the degree implied by the methods employed to determine them. Truck -mounted drilling equipment was used to advance the borings. Samples of the soils encountered in ' the borings were obtained using thin -walled tube and split -barrel sampling procedures. In the thin -walled tube sampling procedure, a thin -walled, seamless steel tube with a sharp cutting edge is pushed hydraulically into the soil to obtain a relatively undisturbed sample. Geotechnical Engineering Report Edwards Ranch Road and Cleartork Main Street Fort Worth, Texas Terracon Report No. 94075310 October 29, 2008 Terracon In the split -barrel sampling procedure, a standard 2-inch O.D. split barrel sampling spoon is driven into the ground with a 140-pound hammer falling a distance of 30 inches. The number of blows required to advance the sampling spoon the last 12 inches of a normal 18-inch penetration is recorded as the standard penetration resistance value. These values are indicated on the boring logs at the depths of occurrence. The samples were extruded in the field, logged, sealed, and packaged to preserve their moisture content and reduce disturbance during transportation to the laboratory. The results of the field exploration program are presented on the Logs of Boring. Figures 2 through 9, in the Appendix. General notes for log terms and symbols are presented on Figure 10. Laboratory Testing The boring logs and samples were reviewed by a geotechnical engineer who selected soil samples for testing. Tests were performed by technicians working under the direction of the engineer. A brief description of the tests performed follows. Liquid limit, plastic limit, percent passing no. 200 sieve tests and moisture content measurements were performed to aid in classifying the soils in accordance with the Unified Soil Classification System (USCS). The USCS is summarized on Figure 11. Hand penetrometer tests were performed on samples of the cohesive soils to evaluate the consistency of these materials. Absorption swell tests were performed on selected samples to evaluate volume change potential at in situ moisture contents. Results of the swell tests are presented in Table 1 below. The results of the other tests are presented on the Logs of Boring. Lime/pH series tests were performed on samples of the soils to determine the appropriate amount of lime treatment required for the subgrade soils. The results of lime/pH series tests are included on Figure 12. Standard Proctor moisture/density relationships were determined on bulk soil samples. These relationships were used to prepare California Bearing Ratio (CBR) Tests to evaluate the subgrade support of the soils. The results of the tests are presented on Figures 13 through 15. Soluble sulfate tests were performed on selected soil samples. The results of the soluble sulfate tests are presented in Table 2. 2__ Geotechnical Engineering Report Edwards Ranch Road and Clearfork Main Street Fort Worth, Texas Terracon Report No. 94075310 October 29, 2008 TABLE 1 — SUMMARY OF SWELL TESTS Initial Final Boring Depth Liquid Plasticity Surcharge No. (feet) Limit (%) Index (psf) Moisture Moisture B-1 2-4 54 33 250 17.4 24.6 B-7 6-8 43 28 750 15.8 18.2 TABLE 2 - SUMMARY OF SOLUBLE SULFATE TESTS Boring Depth Soluble Sulfate No. (feet) (ppm) B-1 0-2 I 537 B-4 0-2 < 100 B-6 0-2 I 518 B-8 3.5 — 5 I < 100 SUBSURFACE CONDITIONS Terrawn Swell N 6.9 1.5 Soil Conditions The conditions encountered at the boring locations are depicted on the Logs of Boring. Descriptions of each layer with its approximate depth and thickness are shown on the boring logs. The layer depths are referenced from the surface present at the time of drilling. Layer boundaries on the boring logs represent the approximate location of changes in soil types; in - situ, the transition between materials may be gradual. A brief discussion of the stratigraphy indicated by the exploration program is presented below. Fill materials consisting of brown, tan, and gray sandy lean clays and clayey sands were encountered at the surface in Borings B-2 through B-6. These fill materials contained limestone fragments and occasional calcareous nodules and sand seams. The fill extended to depths of about 3 to 7'/ feet in' the borings. Samples of these fill materials had Liquid Limits (LL's) 3- Geotechnical Engineering Report Edwards Ranch Road and Clearfork Main Street Fort Worth, Texas Terracon Report No. 94075310 October 29, 2008 llen-acon between 30 and 40 percent, with Plasticity Indices (PI's) between 14 and 21. These fills were generally hard in consistency. Beneath the fill materials in Borings B-2 through B-8 and at the surface in Boring B-1, dark gray, gray, tan, and brown clays, sandy clays, and clayey sands were present. Calcareous nodules and deposits were often found in the samples. They extended to termination depths of 10 to 15 feet in the borings. They had Liquid Limits (LL's) of 25 to 54 percent and Plasticity Indices of 14 to 28, and classified as CL to CH and SC by the Unified Soils Classification System (USCS). The clays were generally hard in consistency, and the sands were generally medium dense to very dense. Groundwater Conditions The borings were advanced in the dry using auger drilling techniques which permits observation of groundwater during drilling. Groundwater seepage was encountered in Boring B-2 during drilling at a depth of 13 feet. No groundwater was present upon the completion of drilling the borings. These observations represent only current groundwater conditions, and may not be indicative of other times or at other locations. Groundwater conditions can change with varying seasonal conditions, landscape irrigation, and other factors. ENGINEERING RECOMMENDATIONS General Site Grading Existing grades along the alignment are relatively level. For the section of Edwards Ranch Road, cuts and fill are anticipated to be up to 7 feet and 2 feet, respectively. Anticipated cut and fill depths in the Clearfork Main Street section are up to 3 feet. The on -site soils free of rock greater than 4 inches in maximum dimension are suitable for use in general site grading. Imported material should be a clean soil with a Liquid Limit preferably less than 60 percent and no rock greater than 4 inches in maximum dimension. . Prior to placing any fill, the areas to receive fill will need to be stripped and grubbed. Any soft or pumping areas should be excavated to firm ground and properly backfilled. The subgrade should be scarified to a minimum depth of 6 inches and uniformly compacted to a minimum of 95 percent of ASTM D698 at a minimum of-+2 percent above the optimum moisture content as determined by that test. The fill materials should then be spread in loose, relatively horizontal lifts, less than 9 inches thick, and uniformly compacted to the same criteria. If filling is Geotechnical Engineering Report Edwards Ranch Road and Clearfork Main Street Fort Worth, Texas Terracon Report No. 94075310 October 29, 2008 Trrracon suspended and the subgrade becomes desiccated or rutted, it should be reworked prior to placement of a subsequent lift. Lime/Sulfate Induced Heave The laboratory tests indicate that soluble sulfate content in the soils was generally on the order of 550 ppm or less. When the sulfate concentrations are less than 3,000 ppm, the subgrade soils are considered to be suitable for lime stabilization in the conventional manner using a single lime application. Imported fill material should be.tested for soluble sulfate to evaluate the suitability of soils for lime stabilization. Pavement Subgrade Preparation Subgrade 'materials encountered consisted of sandy clay soils. Lime stabilization is recommended beneath the planned rigid (concrete) pavements. We recommend that a minimum of 7 percent lime, (TxDOT Item 260), by dry weight,' be used to treat the subgrade soils at this site. The lime should be thoroughly mixed and blended with the top 6 inches of the subgrade (TxDOT, Item 260). The lime stabilized subgrade should be uniformly compacted to a minimum of 95 percent of ASTM D698 at -1 to +3 percent of optimum. moisture content determined by that test. Pavement subgrades should be protected from traffic or ponding water. They should be moist cured until the pavement is placed. Site grading is generally accomplished early in the construction phase. However as construction proceeds, the subgrade may be disturbed due to utility excavations, construction traffic, desiccation, or rainfall. As a result, the pavement subgrade may not be suitable for pavement construction and corrective action will be required. The subgrade should be carefully evaluated at the time of pavement construction for signs of disturbance or excessive rutting. If disturbance has occurred, pavement subgrade areas should be reworked, moisture conditioned, and properly compacted to the recommendations in this report immediately prior to paving. Pavement Sections Pavement design for this project is based on procedures outlined by AASHTO for concrete paved roads, and the city of Fort Worth Pavement Design Standards Manual. The. design parameters used in the analysis are presented in Table 3.

GENERAL COMMENTS Terracon should be retained to review the final design plans and specifications so comments can be made regarding interpretation and implementation of our geotechnical recommendations in the design and specifications. Terracon also should be retained to provide testing and observation during excavation, grading, foundation and construction phases of the project. The analysis and recommendations presented in this report are based upon the data obtained from the borings performed at the indicated locations and from other information discussed in this report. This report does not reflect variations that may occur between borings, across the site, or due to the modifying effects of weather. The nature and extent of such variations may not become evident until during or after construction. If variations appear, we should be immediately notified so that further evaluation and supplemental recommendations can be provided. The scope of services for this project does not include either specifically or by implication any environmental assessment of the site or identification of contaminated or hazardous materials or conditions. If the owner is concerned about the potential for such contamination, other studies should be undertaken. 7 Geotechnical Engineering Report Edwards Ranch Road and Clearfork Main Street Fort Worth, Texas Terracon Report No. 94075310 October 29, 2008 lrerracon This report has been prepared for the exclusive use of our client for specific application to the project discussed and has been prepared in accordance with generally accepted geotechnical engineering practices.

In low permeability soils, the accurate determination of groundwater levels may not be possible with only short-term observations. DESCRIPTIVE SOIL CLASSIFICATION: Soil classification Is based on the Unified Classification System. Coarse Grained Soils have more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine Grained Soils have less than 5W* of their dry weight retained on a #200 sieve; they are principally described as days If they are plastic, and slits If they are slightly plastic or non -plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse -grained soils are defined on the basis of their in -place relative density and fine-grained soils on the basis of their consistency.

Boa 17300 Fort Worth, Texas 76102-0300 Pamphlet No. 1150-2-1 31 October 2003 Local Cooperation CRITERIA FOR CONSTRUCTION WITHIN THE LIMPTS OF EXISTING FEDERAL FLOOD PROTECTION PROJECTS 1. Pamphlet Purpose. This pamphlet provides guidance to individuals, developers, architect -engineering firms, local project sponsors, and local governmental agencies for the construction of new facilities or the modification of existing facilities within the limits of an existing Federal flood protection project constructed by the U.S. Army Corps of Engineers, Fort Worth District (CESWF) and for which local project sponsors and/or local governmental agencies have the responsibilities for operation and maintenance. The CESWF, in accordance with Title 33 CFR, Section 208.10, retains the right of review and approval on all proposed improvements and/or modifications that are passed over, under, or through the walls, levees, improved channels, or floodways of such projects. The guidance contained in this pamphlet applies to the activities described herein in most cases; however CESWF reserves the right to reconsider this guidance at any time due to unknown or unforeseen circumstances, technological advances, additional information, etc. 2. Applicability. This pamphlet applies to all Federal flood protection projects constructed by CESWF, and for which a letter of assurance agreeing to the operation and maintenance of the flood protection project has been furnished CESWF by the project's local sponsor. 3. Project Purpose. A Federal flood control project is designed to safely carry floodwater within the project and through a developed area. As such, any proposed developments within the project must keep the safe passage of floodwater as the first priority. The roles of the CESWF and the project local sponsor are to maintain the integrity of the project while preventing negative impacts to the passage of the project design flood. The CESWF will not allow the safetyof the project to be compromised or the required design carrying capacity of the project reduced. 4. General Criteria for Construction Within a Floodway. a. As early as possible during the planning process, discuss preliminary proposals with the CESWF and the local sponsor to avoid major revisions or project delay. The local sponsor may make any requirements of this Pamphlet more stringent than those contained herein. Concept proposals may be submitted for review. Submit the proposed construction starting date and the detailed project construction schedule, including sequence of construction prior to initiation of work b. Construction may not start until final written contract drawings and plans have been reviewed and approved in writing by both the CESWF and the local sponsor. c. Furnish five (5) sets of plans and specifications for the proposed work to the CESWF, Operations Division, ATTN: CESWF-OD-M, via the local sponsor sufficiently in advance of proposed construction to allow adequate time for review and approval. A vicinity map shall be included in the plans showing the right-of-way boundaries of the flood protection project with specific levee toe and channel slope limits in the portion of the project being crossed, if applicable. This vamvhlet supersedes SWFP 1150-2-1 dated 15 October 1985. OL d. If boring, jacking, or tunneling operations are planned, detailed designs, calculations, and construction procedures must be provided for review. See subsequent paragraphs for additional details and required procedures- e. Practice approved construction methods and best management practices to minimize erosion at the construction site. All work shall be performed in such a manner as to be as environmentally friendly as possible. This includes making every effort to reduce the turbidity of the water at the site, such as by limiting the amount of time construction equipment is in the water. A storm water pollution prevention plan (SWPPP) must be included in the final project submittal. f. When construction work is in progress in a project located downstream of a Federal darn, a request from the contractor for changes in regulated releases will be considered on individual cases only. Normally, regulated releases from upstream lakes for evacuation of floodwaters, water supply, recreation, or other purposes considered to be in the best interest of the public will have fast consideration. A flood event could occur at any time during construction activities and could affect these activities. g. Construction equipment, spoil material, supplies, forms, buildings for inspectors, labs, or equipment and supply storage buildings, etc., shall not be placed or stored in the floodway during construction activities. Any item that may be transported by flood flows shall not be stored within the project. Locations of construction trailers and stockpile areas shall be included on project plans and approved by the CESWF and the local sponsor. h. In addition to other requirements set forth in this Pamphlet, permits may be required under Section 10 and Section 404 for the desired work. These permits require a minimum of 90 days to process. It is recommended that contact with the CESWF Regulatory Branch be initiated in the early planning stages to prevent delays. i. Repair or replace any maintenance and operation roads disturbed during construction to a condition equal to or better than their condition before construction. All roads must be inspected by the local sponsor prior to completion of the project. j. Compact all fill and backfill in 6-inch lifts as specified in job specifications approved by the CESWF. Compaction shall be to at least 95 percent of modified density as specified in ASTM D-1557. All backfill shall consist of impervious materials. Reestablish vegetation to its original condition or better. Remove all excess material from the limits of the floodway. k. Provide scour protection consisting of articulating revetment system protection capable of being re - vegetated at the outfall of stilling basins designed according to the issuing jet velocity. If approved by the local sponsor, riprap, gabions, or concrete paving may be substituted for the revetments. 1. The crown or crest of the levee referred to in this pamphlet is the original or design levee crest elevation. This may or may not be the same as the current levee crest elevation. All modifications shall be based on the higher of the two elevations. m. Upon request, the CESWF Hydrology and Hydraulics Section may provide applicable hydraulic models to be used for design. n. Any permanent disturbance of existing recreation facilities must be mitigated. o. Sump areas adjacent to federal projects are considered an integral part of the federal project and any modifications to them will be reviewed and approved in accordance with this Pamphlet. SWFP 1150-2-1 5. Crossing Over Existing Levees At Grade. a. The local sponsor may decide to not allow any proposed crossing over existing levees at grade. b. No excavation or notching will be performed into or on the levee, or within the levee template. c. Strip topsoil from the levee and place the line up and over the levee template slopes at grade. This will require rather abrupt line grade changes at the levee crest. Cover the new line by placing new fill uniformly on the slopes and top of the levee to slope away from the line and parallel to the longitudinal axis of the levee. Provide a minimum of 2 feet of cover over the new line. The slope of the fill shall be 1 vertical on 20 horizontal or flatter. Replace the topsoil, reestablish grass on all disturbed areas, and restore any roadways. d. All valves located within 15 feet of either side of the projected toe of the levee shall be provided in a concrete box enclosure with a manhole type cover. Valve boxes located within the floodway shall be underground and flush with the surface. If the valve box is placed in the levee crest, the bottom of the excavation shall be not lower than one foot above the design water surface elevation. Fill shall be uniformly placed to slope away from the top of the valve box. If possible all valves shall be placed on the landside of levees a minimum of 15 feet from the projected levee toe. e. Provide water -tight sealed manhole covers for all manholes within the floodway having tops below design water surface elevation. Fasten manhole covers to the manhole structures. 6. Crossing Under Levees with Open Excavation. a. Provide a temporary ring levee (cofferdam) on the riverside of the existing levee at the location of the subject crossing to the same top elevation as the existing levee. This ring levee shall have a minimum crest width of 10 feet and sides slopes of 1 vertical on 3 horizontal or flatter. Construct the levee of impervious materials according to the provisions specified in Paragraph 4j. b. When the temporary ring levee is complete, excavate through the existing levee using one vertical on three horizontal cut slopes. The toe of the levee and ring levee shall be a minimum of 20 feet (measured horizontally) from the top edge of the excavation. c. Generally, sources for borrow materials shall not be located within the limits of the floodway right-of-ways. In addition, depending on the type of soil and whether or not pervious materials or unstable materials exist in the foundation of the existing levee, it may be desirable to limit the depth of excavation or specify a minimum distance from the land -side toe of the levee. All excavated slopes shall be properly designed and the drawings sealed by a registered professional engineer. d. After the line has been placed, the open excavation will be compacted in accordance with Paragraph 4j. When backfill operations are completed, the entire foundation area to be occupied by the replaced levee fill shall be scarified, plowed, and/or harrowed to a depth of 6 inches, and then compacted by at least 16 complete passes of the tamping roller or 95 percent modified density, whichever is more rigorous. e. Accomplish levee replacement by placing fill in 6-inch lifts and compacting by not less than eight complete passes of a tamping roller or at least 95 percent modified density. After compaction, the moisture content shall be within the limits of 3 percentage points above optimum to 2 percentage points below optimum moisture content. SWFP 1150-2-1 3 rn f. Determine the in -place moisture content and density of the levee fill on a frequency of about one sample for each 2500 cubic yards of backfill placed in the levee. g. When the breached levee has been reconstructed to its original grade, remove the temporary ring levee and dress and turf the surface areas of the plugged section. h. Provide water -tight sealed manhole covers for all manholes within the flood protection project having tops below design water surface elevation. Fasten manhole covers to the manhole structures. i. For pipelines, install a positive cut-off structure to prevent water from the riverside flowing through the pipeline to the landside. If located on the riverside of a levee, extend the cut-off structure to the levee crown elevation by bridge. This structure must be accessible no matter what flood condition may exist. The closure device must be operational by manpower, if necessary. j. Provide gravity storm drains discharging into the floodway with automatic flap gate(s) at the discharge end of the line and energy dissipaters, as required. The owner or local sponsor, as per written agreement, shall be responsible for inspection and maintenance to ensure proper operation of the flap gates. k. Use monolithic conduits or conduits with water -tight joints under the levee and levee template. 7. Crossing Under Levees with Boring or Jacking of Sleeves. The sequence of work shall be as follows: a. Excavate the boring and jacking pit (must be on the land side outside the projected toe of the levee template slope). b. Bore and jack the sleeve to a point beyond the projected riverside toe of the levee template slope. c. If the difference in the diameters of the bore and sleeve exceeds 3 inches, the annular space shall be pressure grouted with bentonite slurry. d. Place the product line in the sleeve. e. Pressure grout the product line in sleeve with bentonite slurry. £ Excavate the pit on the riverside and construct a manhole with gate valve placed on inside face of manhole away from channel. Tie line from sleeve under levee into manhole with gate valve. g. Tie line from sleeve under levee into a manhole on landside. h. During work on items a through h, a plug will be required to be placed and braced at the open end of the sleeve and pipe located in the jacking pit at the close of work each day. This plug must remain in place until the gate valve is installed and connections made to ensure protection from flooding from the river. 8. Horizontal Directional Drilling Under Levees and Channels. a. Detailed contractual drawings, plans, procedures, and engineering calculations shall be provided to CESWF for review. These must include all the requirements of Paragraph 4 above and the following additional items: (1) Inside diameter of the final bore hole and outside diameter of the product casing. SWFP 1150-2-1 (2) Detailed description of construction and horizontal boring methods to be utilized- (3) If the difference in the diameters of the final bore and product casing exceeds 3 inches, provide the method of pressure grouting the annular space between the outside of the product casing and the inside of the bore to prevent seepage under the levee template during maximum river stages. (4) A profile of the proposed line showing alignment (including location of the river and levees). (5) Location of entry and exit points, location, elevations and proposed clearances for all utility crossings and structures (6) Right-of-way lines, property, and other utility right-of-way or easement lines (7) Depth under the base of the levee, depth of the line under the river channel, and location of both ends of the string. If the proposed depth of the string directly below the base of the levee is less than 30 feet, then detailed engineering calculations sealed by a registered professional engineer shall be provided for review. These calculations must show a minimum 1.5 factor of safety against hydro -fracturing to be acceptable. b. Develop and provide a quality control plan for the project that includes the maximum allowable drilling pressure, gage calibration method, and responsibility for assuring that the pressure is not exceeded. c. The minimum clearance distance from the top of the pipe encasement to the original design river bottom elevation shall be 7 feet. Should the existing channel bottom elevation be lower than original design grade, the new line shall be the discussed depth below the existing bottom elevation. d. Develop and provide a quality control plan for the project that includes the maximum allowable drilling pressure, gage calibration method, and specific responsibility for assuring that the pressure is not exceeded. During the drilling process, the pressure in the borehole must be monitored to ensure that the operational drilling pressures remain within the safe limits to prevent soil fracturing. The name of the party responsible for monitoring the work must be specified. 9. Bridges Crossing Levees. a. The bottom of low steel of the bridge shall be above the design crest elevation of the levee. No notching into the levee will be allowed. b. All bents should be located to minimize the number of bents located within the template of the levee. Driving of piles within the template of the levee will not be allowed. Bents at these locations should only be designed as drilled piers. c. Bridges will not be located where their construction will block maintenance access roads presently located within the floodway. d. All storm water runoff from bridge decks must be piped to grade to prevent erosion within the floodway. e. Re -vegetated mat type slope protection must be provided from the top of the levee to the floodway bottom under the shadowline of the bridge. SWFP 1150-2-1 5 f_ The bridge must be designed to minimize the number of pier bents. If the new bridge is within 500 feet of an existing bridge the new pier bents must be in alignment with the adjacent bridge. 10. Buried Lines Parallel to Levees and Channels. a. Buried lines parallel with a levee (either on the river side or land side) will not be allowed where the buried lines final location will be within the extended template of the levee. For example, a line buried 5 feet deep must be at least 15 feet away from the toe of a levee with a 1 vertical on 3 horizontal slope. b. Sumps, ditches, swales, or other project features crossed by the buried line shall be restored to their pre construction condition. c. Buried lines parallel with the channel bank must be at least 25 feet from the projected river channel slope template. d. When a buried line crosses a discharge channel, place the line on piers with the piers aligned so as to provide minimal obstruction to flow in the discharge channel and designed so as to catch minimal debris. The preferred alternative would be to place the line under the discharge channel and encase it with concrete. Extend the encasement a minimum of 5 feet beyond the top of the channel side slopes. 11. River and Channel Crossing Criteria. a. Crossings Under Rivers and Channels by Open Excavation_ (1) Bury the line a minimum of 7 feet below the original design river bottom elevation. Should the existing channel bottom elevation be lower than original design grade, the new line shall be the discussed depth below the existing bottom elevation. (2) Sufficiently anchor or encase the line to prevent floatation. (3) Backfill the excavation with material similar to that excavated. If soil is excavated, backfill with compacted impervious fill material and if rock is excavated, backfill with concrete. (4) No cofferdam fill type crossings shall be allowed in water greater than six (6) feet in depth, and will then only be allowed if geotechnical and structural designs prove that sheet piling would not be a viable method. b. Crossings Over Rivers and Channels. (1) Provide a minimum freeboard between the low point of the crossing and the design water surface elevation of three feet or to the top of any levee, whichever is higher. (2) The obstruction caused by the supporting bridge and its piers shall not significantly reduce the carrying capacity of the floodway. No longitudinal cross bracing will be used. (3) Submit final plans and hydraulic computations to indicate that the proposed project would not reduce the floodway capacity. (4) Projects crossing navigable waterways (Trinity River downstream from Riverside Drive in Fort Worth, Texas) shall require a United States Coast Guard permit. Clearances and requirements shall be as directed by the Coast Guard. SwFP 1150-2-1 6 12. Roadway or Railroad Crossings. a. The low steel of a bridge shall have an elevation not lower than the crown of the levee or top of bank or 3 feet above the design water surface, whichever is higher. Contact CESWF for the current design water surface at the location of the proposed roadway crossing. Additional clearances shall be required for fixed spans over navigable waterways. b. Submit final plans and hydraulic computations to indicate the proposed roadway or bridge would not reduce flows or project capacity. Projects will not be approved that reduce the carrying capacity of the project c. Any roadway over a navigable waterway will require a permit from the United States Coast Guard. d. See Paragraph 9 for special requirements for crossing levees. e. Hold temporary roadway fill to a minimum to prevent increasing the water surface elevation should a flood occur during the construction period. Construct all temporary ramps from levees going in a downstream direction. This will prevent flows from being directed into the face of the levees. 13. Headwall, Chutes, Gate Valves, Flap (Automatic) Gates, etc. a. Install headwall, gate valve structures, flap (automatic) gates, and other types of outfall structures in such a manner to prevent obstruction of flow or creation of scouring conditions within the project All headwalls must transition with the slope and flow discharge points must be at an elevation equal to the bottom of the slope or at the normal water surface. Chutes will not be allowed unless they are the only viable alternative. b. All structures shall be installed in such a manner so as to not create maintenance problems. 14. Pump Discharge Pipelines Over Levees. a. The invert of the discharge shall be at the toe of the protective works (levee) and shall be free -vented at the highest point For very large lines deviation from this criteria may be considered, but under no condition shall excavation be permitted into the levee. See Paragraph 5 for requirements for crossing over a levee on grade. b. Flap (automatic) gates are not required at the outfall of the discharge lines. 15. Electrical and Telephone Criteria for Overhead Wire Crossings. a. The local sponsor may require directional boring under the levee as opposed to an overhead crossing. b. No structure (poles or otherwise) shall be located closer than 15 feet from the toe of any levee. c. No structure (poles or otherwise) shall be located closer than 15 feet from the top of any channel slope. d. Provide a minimum vertical clearance of 28 feet between the crown of the levee and the low wire at the low point of the wire at the levee crossing computed under the most adverse conditions (temperature, wind, load, etc.). SWFP 115O-2-1 e. Provide a minimum vertical clearance of 28 feet between the natural ground and the low wire at the low point of the sag in the area of the project channel, or three feet above the project design water surface level, whichever is higher. (Check Electrical Code for minimum clearance of high voltage lines.) f. Locate guy wires and anchors in such a manner that they do not interfere with the operation and/or maintenance of the channel, levees, or related structures. No anchors may be placed on the levee. 16. Low Dams or Diversion of Flows. a. Submit plans, hydraulic and structural computations, and specifications for low dams or other obstructions for review and comments prior to the construction of any type dam structure in a project area. These plans will be reviewed to determine if adverse hydraulic or structural effects would occur within the project as a result of the proposed construction. Prior to an extensive engineering study for any type of water barrier in a project, the CESWF and the local sponsor will review the concept plan, proposed location, and purpose. b.

The proposed 48" & 36" pipeline has a total approximate length of 1,160 linear feet. The proposed 48" & 36" diameter water pipeline will be offered for bid with the dielectrically coated carbon steel pipe material alternative: ,e Upon completion of the corrosivity evaluation, a corrosion protection design was prepared including the requirements for joint bonding, electrical isolation, stray current control, corrosion monitoring test stations and cathodic protection. This report presents the results of the corrosivity evaluation and corrosion protection design. 2.0 EXECUTIVE SUMMARY 2.1 Based on analyses of the electrolyte characteristics, the soil is classified as corrosive with respect to the dielectrically coated steel pipe with 33.3% of the measurements less than 3,000 ohm -cm in the 5 to 10 foot layer. Furthermore, wide variations in soil resistivity can promote the formation of concentration cells that lead to corrosion. 2.2 Soils along the proposed pipeline route are considered corrosive to the dielectrically coated steel pipe material. Therefore, corrosion protection measures are recommended for this pipe material to preserve the physical integrity of the pipeline. 2.3 The dielectric bonded coating on the steel pipe is the primary corrosion control mechanism. However, corrosion will occur at those areas where there are breaks (holidays) in the coating. Therefore, the coating must be supplemented with cathodic protection. The installation of a cathodic protection system is therefore recommended for the dielectrically coated steel pipe to mitigate corrosion at coating holidays. 2.4 Joint bonding at all mechanical connections is also required. 2.5 The evaluation indicates that stray direct currents and stray alternating aw currents may be a concern for the pipeline integrity. The installation of test stations to monitor possible DC and AC interference are recommended. 2.6 Test stations should be installed at all cathodically protected foreign pipeline crossings, cased crossings, major road crossings, cathodic protection magnesium anode ground bed locations, and at the location of all in -line underground electrical isolators to monitor the effectiveness of the proposed corrosion protection system and to allow for AC and DC interference testing. 3.0 CORROSIVITY EVALUATION 3.1 SUMMARY The soil corrosivity analysis and corrosion control recommendations presented in this report are based on the field soil resistivity survey and laboratory soil analysis conducted by Corrpro Companies, Inc. During the VW field evaluation Corrpro also investigated the possibility of interference due to stray DC currents and overhead high -voltage AC power lines, which might affect the physical integrity of the proposed water pipelines. The evaluation performed is the basis for determining the corrosion protection requirements for the 48" and 36" W-1 & W-lA Clearfork Water Line project. 3.2 RESULTS AND ANALYSIS Field and laboratory testing was performed to collect chemical and electrical data pertaining to the corrosivity of the proposed pipeline alignment with respect to the dielectrically coated carbon steel pipe. c, MW Soil resistivity measurements were recorded from grade to depths of five feet, five to ten feet and ten to fifteen feet at three (3) locations along the proposed right-of-way. This data is recorded in Appendix A. Using the Barnes Layer procedure, soil resistivity was calculated for the 5 to 10 feet and 10 to 15 feet layers for the proposed route. Statistical distribution of the soil resistivity for the layers of interest, where the pipeline is to be installed, is summarized as follows: Citv of Fort Worth 48" & 36" Diameter Clearfork Main Street Waterline Proiect Soil Resistivitv 5-10 Feet 10-15 Feet •.

Laboratory test results are tabulated in Appendix B. With respect to the chemical properties of the soil, the test results of the samples indicate the following: Moisture content: 4.7% - 13.0% pH: 8.0 — 8.4 Chloride ion concentration (ppm): 8.0 —18.0 ,. Sulfide ion concentration (ppm): 0.0 Conductivity (microhmos): 310 — 1,000 Resistivity (ohm -cm.): 1,000 — 3,200 VO Considering each of the chemical and electrical soil properties that are tested in the field and the laboratory, general guidelines for interpreting the results are as follows: ., Soil Moisture - The higher the soil moisture content, the greater the anticipated rate of corrosion. Moisture contents typically range from .. 1 % (very dry sands) to 40% (clays holding a great deal of moisture). Typical values are 10 to 15% with over 20% moisture considered high. pH - Acidic soils and groundwater are more conducive to galvanic corrosion of ferrous materials than alkaline soils and groundwater. Chloride Concentrations - Chloride ions are cathode depolarizers, which enhance the rate of corrosion. The higher the concentration, the greater the rate of corrosion. Many soils have chloride concentrations less than 10 ppm. Concentrations over 50 ppm are significant from a corrosion standpoint. Sulfide Concentration - Any detectable concentrations of sulfide ions are indicative of anaerobic conditions that may support high rates of metal dissolution due to microbiologically influenced corrosion. Conductivity - For a given corrosion cell with a fixed potential difference between the anode and cathode, the higher the conductivity, the greater the metal loss. Conductivities over 350 microhmos/cm (equivalent to a resistivity of 2850 ohm -cm) are considered high. Soil Resistivity - Resistivity is a common parameter for evaluating the corrosiveness of the soil. Resistivity is the inverse of conductivity and is measured in units of ohm -centimeters. Corrosivity is often an inverse function of resistivity with low resistivity soils usually more corrosive than high resistivity soils. Resistivity is also related to the concentration of salts with low resistivity indicating high levels of salt. The field survey revealed that overhead high voltage power transmission lines do not parallel the proposed pipeline alignment. Therefore, induced AC voltages from high voltage power transmission lines installed near the proposed pipeline alignment are not a concern. However, foreign cathodic protection systems are present in the area and could affect the pipeline integrity. 3.3 CORROSION PROTECTION REOUIREMENTS An analysis of the field data obtained during the survey and of the types of proposed pipe materials was made to determine the requirements for and .. types of corrosion protection that could be considered for the City of Fort Worth 48" & 36" diameter W-1 & W-lA Clearfork Main Street waterline. Low soil resistivity, high moisture content and areas with concentrations of chloride ions along the proposed pipeline alignments indicate that ferrous materials will be subject to electrochemical corrosion. Joint bonding will be required to maintain electrical continuity at all non - welded pipeline joint locations. The dielectric coating on the steel pipe is the primary corrosion control mechanism. Corrosion will occur, however, at those areas where there are breaks in the coating. Therefore, the coating must be supplemented with cathodic protection through out the length of the proposed pipeline. In summary, it is recommended that cathodic protection should be ago installed on the 48" & 36" diameter Clearfork Main Street Water Line project W-1 and W-lA pipeline. It is necessary to electrically isolate the pipeline at all tie-ins to other buried metallic pipelines regardless of the type of metallic pipe material. In addition, where the pipe passes through casings, the carrier pipe in the casings must be electrically isolated from the casing. Monitoring test stations should be installed for the pipeline at cathodically protected foreign pipeline crossings, cased crossings, and major road crossings, galvanic anode ground beds and at the location of in -line underground pipeline isolators. 4.0 CORROSION PROTECTION DESIGN REPORT 4.1 SUMMARY The proposed 48" & 36" diameter W-1 & W-lA dielectrically coated carbon steel pipeline will be offered based on the following configurations: A corrosion control system consisting of galvanic magnesium anode cathodic protection, joint continuity bonds for all non - welded joints, monitoring test stations, joint isolation at connections to existing pipelines and electrical isolation at cased crossings is recommended for this pipeline configuration. 4.2 PROTECTIVE COATINGS A polyurethane coating system shall be used to prevent corrosion of the external surfaces of the carbon steel pipeline. The polyurethane coating shall be in accordance with the ANSI/AWWA C222 Standard. All welded and/or mechanical joints should be coated with heat shrink sleeves. Proper installation of the heat shrink sleeve must be assured to prevent any delamination between the coated pipe and the sleeve. 4.3 PIPE BEDDING & BACEFILL There may be places along the pipeline right-of-way where the pipe may be installed in rocky areas. It is essential that the pipe be provided with proper bedding to prevent physical damage to the pipe, mortar and/or dielectric coating. It is recommended that bedding materials such as clean river sand be used for this purpose. Backfill material should also be finely graded to prevent damage to either the dielectric or mortar coating. 4.4 CATHODIC PROTECTION The recommended galvanic magnesium anode cathodic protection system .. for the 48" & 36" diameter Stonegate (Clearfork Main Street) W-1 & W- lA Pipeline shall include two (2) anode ground beds each consisting of twelve (12), 20-pound elongated prepackaged magnesium anodes. Refer to Appendix E for Specifications on Galvanic Anode Cathodic Protection System components. 4.5 JOINT BONDING AND ELECTRICAL ISOLATION The 48" & 36" diameter Stonegate (Clearfork Main Street) W-1 & W-lA water transmission pipeline should be electrically isolated from existing metallic pipeline mains and laterals. The pipeline also requires two bonding wires across each non -welded mechanical joint. Refer to Appendix C, Joint Bonding and Electrical Isolation. 4.6 TEST STATIONS Test stations will allow periodic monitoring of the effectiveness of the cathodic protection system. Refer to Appendix D for Specifications on Corrosion Control Test Stations Test stations are required for the pipeline at cathodically protected foreign pipeline crossings, cased crossings, major highway crossings, and electrically isolated tie-ins from laterals and spur lines. MW .. Test Station types are as follows: 1. TS - Standard pipe -to -soil potential measurement test station at grounded locations (see TS type test station on the cathodic protection drawings). 2. CC - Test station installed at the ends of metallic pipeline casings with 2 lead wires to the pipeline and 2 lead wires to the casing (see CC type test station on the cathodic protection drawings). CC test stations shall be installed at both ends of all metallic casings. 3. FL - Test station installed at crossing of underground, cathodically protected piping systems owned by others (foreign pipelines), (see FL type test station on the cathodic protection drawings). 4. IF - Test station installed across underground electrical isolation joints. (see IF type test station on the cathodic protection drawings). Note: Lead wires and bond wires are to be installed on the foreign pipelines by the foreign pipeline owners. The City of Fort Worth will make arrangements with the foreign pipeline owners (if any) for installation of lead wires and bond wires on the foreign pipelines. Contractor SHALL NOT install test lead wires or bond wires on foreign pipelines. 4.7 CONCLUSIONS AND RECOMMENDATIONS 4.7.1. The installation of galvanic anodes along the pipeline alignment will provide the means for external corrosion control for the 48" & 36" Diameter Clearfork Main Street Water Pipeline project. 4.7.2 The proposed water pipeline options should be electrically isolated from existing metallic transmission mains, laterals and plant facilities. 4.7.3 Joint bonding at non -welded mechanical connections is also required. .. .. 4.7.4 Proper monitoring of the cathodic protection system will be achieved through test stations installed at cathodically protected foreign pipeline crossings, cased crossings, galvanic anode ground beds and buried isolation fittings. In addition, permanent reference cells will allow monitoring at ground bed locations and at buried isolation fittings.

The project involves installation of new water and sanitary sewer lines in Fort Worth, Texas. A site vicinity map is presented on Plate 1. The purpose of this geotechnical investigation is to provide geotechnical information at the proposed water and sanitary sewer locations. 1.2 Geotechnical Investigation Program The primary objectives of this study were to gather information on subsurface conditions at the site and to provide recommendations for the proposed utilities. The objectives were accomplished by: 1. Drilling eighteen borings to determine soil stratigraphy and to obtain samples for laboratory testing; 2. Performing laboratory tests to determine physical and engineering characteristics of the soils. Subsequent sections of this report contain descriptions of the field exploration, laboratory -testing program and general subsurface conditions. ,m 2 FIELD INVESTIGATION 2.1 Geotechnical Borings The field exploration program undertaken at the project site was performed on July 10 and 14, 2006 and November 20, 2008. Subsurface conditions were investigated by drilling a total of eighteen (18) borings as follows: five 20-foot, seven 25-foot, five 30-foot and one 40-foot soil borings below the ground surface. A site plan showing the approximate boring locations is presented on the Plan of Borings, Plate 3. 2.2 Sampling Methods Soil samples were obtained continuously to 10 feet and at 5-foot intervals thereafter. Cohesive soil samples were obtained with a three-inch thin -walled (Shelby) tube sampler in general accordance .. with ASTM D-1587 standard. Split spoon samplers were used in cohesionless soils and where sample recovery in cohesive soils using the thin -walled tube was not possible. Each sample was removed from the sampler in the field, carefully examined and then classified. The shear strength of the cohesive soils was estimated by a hand penetrometer in the field. Suitable portions of each .. sample were sealed and packaged for transportation to our laboratory. Augering was performed when rock was encountered and TxDOT cone penetrometer test was performed at approximately 5-foot intervals in the rock. The TxDOT cone test is used to determine the relative density or consistency of a soil material. The test consists of driving a 3-inch diameter cone with a 170-pound hammer, which is dropped for a distance of two feet. The cone is seated and driven to 12 blows or 6 inches whichever comes first. Then it is driven for two consecutive 6- inch increments, and the blow counts for each increment are noted. In hard materials, the cone is no ., driven with the resulting penetration in inches recorded for the 50 blows. The number of blows for each 6-inch increment and/or the amount of penetration for each 50 blows is presented on the boring logs presented on Plates 4 through 21. Detailed descriptions of the soils encountered in the borings are given on the boring logs presented on Plates 4 through 21. A key to the soils classification and symbols used in the boring logs is also presented on Plates 22 and 23. 2.3 Water Level Measurements Groundwater levels in the borings were observed during and after completion of drilling. The water aw levels measured during and after drilling are reported on the boring logs presented on Plates 4 through 21. 3 LABORATORY TESTING Selected soil samples were tested in the laboratory to determine applicable physical and engineering properties. All tests were performed according to the relevant ASTM Standards. These tests consisted of moisture content measurements, pocket penetrometer, percent passing No. 200 sieve, Atterberg Lin -tits, unconfined compression and unit dry weight. The Atterberg limits and percent passing No. 200 sieve tests were utilized to verify field classification by the Unified Soils Classification System, and the unconfined compression tests were performed to obtain the undrained shear strength of the soil. The type and number of tests performed for this investigation are summarized below. Type of Test Number of Tests �+ Moisture Content (ASTM D2216) 126 Atterberg Limits (ASTM D4318) 29 Percent Passing No. 200 Sieve (ASTM D1140) 22 Hand Penetrometer 78 Unconfined Compression (UC) (ASTM D 2166) 17 Unit Dry Weizht (ASTM D 2166) 17 The laboratory test results are presented on the boring logs on Plates 4 through 21. 4 SITE CHARACTERIZATION 4.1 According to the University of Texas at Austin, Bureau of Economic Geology "Geologic Atlas of .. Texas Dallas Sheet," the project area lies within the surface expression of Alluvium (map symbol Qal) and Fluviatile (map symbol Qt) deposits underlain by Fort Worth Limestone (map symbol Kfd) and Duck Creek Formation (map symbol Kdc) undivided. The Alluvium and Fluviatile deposits .. mainly consist of flood -plain deposits including gravel, sand, silt, silty clay, clay and organic matter. The Fort Worth Limestone is mainly represented by aphanitic to biosparite, burrowed limestone weathers and calcareous clay. The Duck Creek Formation consists of aphanitic and partially bioclastic, locally burrowed limestone and weathers. Geology map is presented on Plate 2. 2 .r 4.2 Soil Stratigra�nhy Our interpretation of soil and groundwater conditions at the project site is based on information obtained at the boring locations only. This information has been used as the basis for our conclusions and recommendations. Significant variations at areas not explored by the project boring may require reevaluation of our findings and conclusions. Boring B-1.

It should be noted that groundwater levels determined during and after drilling may not accurately reflect the true groundwater conditions, and therefore should only be considered as approximate. Also these readings will fluctuate seasonally and in response to rainfall. Other factors that might impact groundwater levels include leakage from existing sewers and/or sanitary sewers. low 5 LIMITATIONS This investigation was performed for the exclusive use of Kimley-Horn and Associates, Inc. for the proposed Stonegate Utilities Relocations in Fort Worth, Texas.

(b) This Agreement does not give the City the right to install any utilities other than the City's Facilities or the right to grant to others the right to install utilities in any part of the Easement Area. (c) The term of the Sewer Main Easement granted shall begin on the date hereof and shall continue until the City abandons its use of the Sewer Main Easement. If the City abandons it use under this Agreement, the City at the request of Union Pacific shall promptly execute and file in the deed records of Tarrant County, Texas a release of this Agreement. If the City fails to execute and file the release promptly, Union Pacific may seek to enforce its rights to a release in any court of competent jurisdiction. (d) Except in cases of emergency, the City and its contractors shall notify Union Pacific at least 48 hours before entering either Union Pacific's Property or the Easement Area so Union Pacific may have a representative or representatives present. If the City enters upon Union Pacific's Property or the Easement Area in case of emergency, the City agrees to notify Union Pacific of such entry as soon as practicable and agrees to inform Union Pacific of the circumstances of the entry and the nature of any work performed within the Easement Area. City acknowledges that the Easement Area is in an active rail yard; City and its contractors shall comply with Union Pacific's safety rules and any contractor performing work on behalf of City shall execute Union Pacific's-standard Right of Entry Agreement. (e) Union Pacific retains all of its rights to use and occupy the surface of the Easement Area not inconsistent with the use by City, its successors or assigns. Notwithstanding the foregoing, Union Pacific agrees that the erection or construction of any permanent building or other structure on or over any part of the Easement Area by Union Pacific, its successors, assigns, or lessees, shall be deemed to be a use of the Easement Area inconsistent with this Agreement. If the Union Pacific erects or constructs any permanent building or structure on or over any part of the Easement Area and fails to remove it promptly after the City's request, then the City shall have the right to enforce its rights under this Agreement by any remedy available at law or in equity, including without limitation, an action of specific performance or temporary restraining order or injunction at Union Pacific's expense.
