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. B.

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 . 02/09/2010 SC-52 - - PART D -SPECIAL CONDITIONS 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. 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.

Auger-Drilled Shaft : An excavation support system composed of a steel casing (usually a segmental corrugated metal pipe [CMP]) grouted in place inside an auger-drilled excavation. A large diameter drill rig is used to excavate a hole slightly larger than the required inner diameter of the shaft. During drilling, the excavation is kept full of drilling fluid (usually polymer-based) with high gel strength , high density, and high viscosity to prevent caving, sloughing, or collapse of the excavation. When the drilling is complete, the prefabricated casing of the required diameter is lowered into the fluid-filled excavation. A concrete seal, of sufficient thickness to resist buoyant forces on the dewatered shaft and to prevent groundwater inflows, is then placed at the bottom of the shaft by tremie . Grout is then placed by tremie between the outside wall of the casing and the excavation wall. When the concrete and grout have cured , the drilling fluid can be pumped out of the shaft. A properly constructed auger-drilled shaft will provide an essentially watertight shaft. Backfill Grouting/Primary Grouting : The injection of a fluid , rapid-setting , grout in shafts to fill the void behind liner plates . Contact Grouting/Secondary Grouting : The injection of fluid , non-shrink, rapid-setting grout into any remaining voids between the backfill grout and the primary support or excavated surface . Liner Plate Shaft: A shaft formed by sequential excavation and erection of support rings consisting of segmental steel liner plates . All voids between the excavation and the liner plates are filled with grout to ensure complete contact with the ground. Secant Pile Shaft : A shaft that is formed by overlapping concrete piles . The concrete is placed using the tremie method , in bored holes that are stabilized with drilling fluid and/or temporary casing . Secant pile shafts may be round or rectangular, using integral steel reinforcement or wales as necessary to support the piles. Secant pile shafts can be constructed to provide a watertight shoring system . Sheetpile Shaft: An excavation suppc5rt sys\er,i: c.onsfsting·of fully interlocking steel sheetpiles driven· o,t vib t*ed ·into pl~ce, ,Nith a concfete tremie slab and/or concrete i.vorking slab de'signed·tq prevent or control groundwater inflows; and to pre.veryt sk>fl heave.

Portal Stabilization : Whe re the new trenchless pipelines enter or exit a shaft excavation , the Contractor shall stabilize the portal to prevent soil/rock or groundwater inflows into the shaft that may lead to settlement around the shaft or flooding of the excavation . Portal stabilization may be accomplished using applicable. ground improvement , double sheeting methods comb ined with contact grouting (guillotine method), or may be integral to the shaft construction method (as for auger-drilled shafts and secant pile shafts). b . Guillotine (Double-Wall) Stabilization Method : To provide stable ground and groundwater control at shaft penetrations , a set of steel sheetpiles is installed just outside the primary shoring system in front of the portal locations. Contact grout is then injected between the primary shoring system and guillotine sheets to confirm that the soil between is stable and will prevent groundwater flow . A hole is then cut in the primary shoring, exposing the stabilized ground and allowing for the insertion of the tunneling equipment into the shaft seal and through the primary shoring . Once the tunneling shield and shaft seal are mated, the guillotine sheets can be lifted out of the tunnel path and removed . c . Ground Improvement: A prism of stabilized soil is created just outside the shoring system using grouting methods appropriate for the ground conditions . The improved block stabilizes the soil and lowers the permeability of the soil sufficiently to control groundwater inflows . It is important that the stabilized prism is cast tightly against the existing shoring , extending well beyond the portal to be cut in the shoring , so that groundwater cannot flow along the shoring and enter the portal. Any grout/soil -cement strength must also be carefully controlled to allow the tunneling equipment to efficiently excavate it. 5. DESIGN CRITERIA a. The Contractor shall provide portal stabilization to prevent soil/rock inflows and to control groundwater inflows during launch and retrieval of the tunneling equipment for all shaft locations. b. Portal stabilization methods shall ensure that no soil/rock and no more than 5 gpm of water enters the shaft when creating portals for the launch or retrieval of the tunneling equipment, as required in Paragraph C 3 a. c . The Contractor may accomplish portal stabilization by the use of ground improvement , the guillotine wall (double-wall) method , methods integral to the shoring system (such as for auger-drilled shafts and secant piles) or by other Contractor suggested methods , subject to the requirements of these Specifications and Engineer's written approval.

DEFINITIONS a. Open-Shield Pipejacking: For the purposes of this Specification, open- shield pipejacking is defined as a technique for installing pipe by jacking it into place from a jacking shaft to a receiving shaft, using hydraulic jacks . Soil excavation is carried out within a shield in front of the lead pipe segment using hand-mining , mechanical methods such as a digger-boom, or with mechanized equipment such as a rotary tunnel boring machine (TBM). The open shield allows access to the excavation face from inside the bore . The shield is steerable using hydraulic jacks to orient an articulated section of the shield, and guidance is provided using a laser, gyroscope, or theodolite system supplemented with a water level if necessary. b . Jacking Pipe: The pipe jacked behind the shield . The jacking pipe shall be specifically designed to be installed by pipejacking. c . Intermediate Jacking Station (IJS): A fabricated steel cylinder fitted with hydraulic jacks spaced around the circumference, which is incorporated into the pipeline between two specially fabricated pipe sections. The function of an intermediate jacking station is to distribute the jacking load along the pipe string during pipe installation. The hydraulic jacks are removed at the completion of a drive and the gap between adjacent pipe sections is fully closed by pushing the pipes together with the main shaft jacks or another IJS . The steel cylinder remains as an extended sleeve or coupling. The steel cylinder must be protected from corrosion, consistent with corrosion protection used for the jacking pipe and joints . d . Launch/Retrieval Seal or Entry/Exit Seal: A mechanical seal usually comprised of one or more rubber flanges attached to a steel housing that is mounted to the wall of the jacking/receiving shaft. The shield or jacking pipe distends the flange seal as it passes through, reducing water, lubrication, and soil inflows into the shaft during pipejacking operations . e. Lubrication/Grout Port: A port located within the shield or in a jacking pipe segment, fitted with a one-way valve, for injection of lubrication material or grout into the annular space between the pipe and the ground . Lubrication ports within the pipe are typically threaded to accept lubrication/grout fittings . Pipe plugs are inserted after grouting is completed. f. Settlement Point: A point with elevation and spatial location established by survey prior to construction . The point is re-surveyed periodically to monitor ground movements . The point may be a nail, pin , subsurface Water and Sanitary Sewer Relocation for SH 121 T SECTION 02341 Open-Shield Pipejacking Page 3 of 17 Crossing West of The Union Pacific Railroad Davidson Rail Yard, Part 2 -Hulen Street Bridge Water Main Extension From Hulen Street to Como Pump Station , Part 2 KHA No. 061018062 March 2010 settlement rod, borehole extensometer, or other device that can be readily located and surveyed. g .

Prior to any new or existing employee of Contractor working at or regularly visiting any Railroad facility, Contractors must register with the Railroad's approved risk assessment company. • Contractors must then present and secure Background Check Consent Forms from each of their employees who are, in the course of their duties, working on Railroad's property or facilities . • Any of Contractor's employees who refuse to provide consent to a background check will not be allowed to conduct work in Davidson Yard or on or near Union Pacific facilities. -• Contractors will then submit SSNs of the individuals they employ who will require a photo identification badge (the "Identification Badge") to the Railroad's approved risk assessment company via the Website . 5 14802924\V-3 • Contract employees ("Contractees") will then submit a photo of themselves and complete the program testing online via the Railroad 's approved risk assessment company's Website. • The program testing requires "Security Awareness" and, in the following cases only when applicable to the type of service being provided by the Contractee, an "Engineering Safety Training Orientation and Test'', a "Mechanical Safety Training Orientation and Test", and an "Automobile Load/Unload Contractor Safety Orientation Course". • After the Contractee satisfactorily completes the examination, a background investig ation is automatically triggered. • The Railroad's approved risk assessment company program will then score the investigation to validate whether an individual meets all the criteria for the Railroad . • When a satisfactory score is rendered, the Railroad's approved risk assessment company will automatically print an Identification Badge authorizing access to Railroad property and mail the Identification Badge to the Contractor's business address for distribution to Contractee. • Contractee is responsible for wearing that badge and carrying another form of government-issu ed ID at all times when on Railroad property. • All communication regarding Contractor's employees should be addressed to: Bill Chandler Union Pacific Railroad Company -Safety Department 137 West 200 North Hyde Park, UT 84318 Phone (435) 563-8253Fax (435) 563-8295 E-mail: WLCHANDL@up .com • Contractor shall be responsible for managing and recovering the Identification Badge from their employees who resign , retire or are terminated . • Railroad shall have the right to reject any candidate to the extent permitted by all applicable law. • To the extent that any portion of these requirements violate a law, ordinance, statute, or regulation that portion shall be ignored and applicant shall comply with all remaining portions of the application process. It is expected that Contractor wilJ be primarily responsible for enforcement of this program; however, both Railroad and the Federal Railroad Administration will be auditing for compliance. Should any Contractor be found out of compliance, any and all fines or penalties incurred will be the sole obligation of Contractor. 1.2 Regulatory Training Requirements Railroad insists on 100% training compliance that is required by all Federal, State and Local Safety Regulations applicable to the NTT A or City in the performance of the work.

They will also receive special instructions relating to the work zone around Railroad machines and minimum distances between Railroad machines while working and traveling. 7.0 Lockout/ Tagout Procedures on Equipment The Contractor must be aware of and Contractor Employees must adhere to applicable State, Federal and Railroad rules and regulations on lockout/tagout. A. Lockout/Tagout Procedures During Work. Where practical, Contractor's equipment shall be serviced, maintained, adjusted or repaired clear of any live track. Follow these steps when servicing, maintaining, adjusting, or repairing equipment during the course of work when On-Track Safety has been established: 14802924\V-3 1. Notify the Railroad Representative and the equipment operators on both sides of your equipment that a lockout/tagout is in progress. Let them know where you are located and in which direction you are working, so they will know whether you are behind them or in front of them . 11 14802924\V-3 2 . Place l orange cone in the center of the track at least 15 feet from each end of your equipment. Note: Other equipment operators are required to stop when approaching an orange cone and may not proceed until it is removed. 3 . Tagout the equipment according to the procedures in Section D. 4 . After completing the maintenance or repair, promptly notify the Railroad Representative and all affected employees that you are discontinuing the lockout/tagout process . 5 . Remove the cones and tags . B. Lockout/Tagout Procedures When Equipment Is Tied Up. When equipment is tied up on a track, follow these steps to service, maintain, adjust, or repair equipment: 1. Ensure that switches leading to the equipment have been lined against the track the equipment is on. • Ensure that switches are spiked, clamped, tagged, and locked to prevent movements onto that track. • If the switches cannot be locked, or ifit is necessary to use part of the track for train or track car movements, you may protect equipment with a derail that is locked in the derailing position 150 feet or as conditions warrant in advance of the equipment. 2 . Apply your scissors lock, personal padlock, and tag to these switches or derails. Note: The scissors lock allows others working on equipment to place their personal padlocks and tags to ensure their own lockout/tagout protection. EXCEPTION: When equipment is tied up under the direct supervision of an employee in charge: • The employee in charge may provide protection as long as he or she can prevent any movements onto that track. • Before beginning work, the operator or mechanic must inform the employee in charge of the operator or mechanic's presence and request permission to work on the equipment. • The employee in charge must not release the limits or allow movements onto the track until he or she communicates with all affected employees to make sure they are in the clear. 3. Place 1 orange cone on each side of your equipment. EXCEPTION: If other equipment is within 15 feet, place the orange cones as far in advance of your equipment as possible. 4. Tagout the equipment according to the procedures in Section D . Note: If other employees are present, conduct a job briefing to discuss the lockout/tagout process being used. 5 . After completing the maintenance or repair, promptly notify the employee in charge and all affected employees that you are discontinuing the lockout/tagout process. 12 14602924\V-3 6. Remove the cones, tags, and locks. 7. When the last lock is removed, remove the scissors lock. C. General Tagout Procedures. Follow these steps to tagout equipment: 1. Apply the equipment's parking brake. 2. Test the brake to make sure it holds the equipment in position. If the brake does not hold, or if you are not sure it will hold, block the equipment to prevent any unexpected movement. 3. Lower all hydraulic components to the ground or secure them with their locking devices. 4 . Mechanically secure all equipment components in a safe condition. Note: Components must be mechanically locked or blocked to prevent any movement of the equipment or component, which could endanger workers in the area. 5. Shut down the equipment at the -operator's controls. 6. Attach a "Do Not Operate" tag at the operator's controls for each worker . 7. Remove the key from the ignition switch of engine powered equipment such as welders, light plants, small compressors, etc . If tl1e ignition key does not remove all electrical control sources, or if the equipment does not have an ignition key switch, place the main battery switch in the OPEN position and secure the battery box. Attach a "Do Not Operate" tag . If the equipment does not have a battery disconnect switch, disconnect the battery leads and attach a "Do Not Operate" tag to the battery lead. Place as many tags as necessary to ensure that the equipment will not be started or energized unexpectedly. 8. Remove any sources of stored energy, including : • Electrical • Mechanical • Hydraulic • Pneumatic • Chemical • Thermal • Any other sources that may activate a component 9 . Follow any special manufacturer procedures to ensure that the equipment is safe for performing maintenance or service. IO. Test the security of the tagout. If the equipment cannot be started and the components cannot be energized, you can start maintenance or service safely. 13 8.0 Railroad's Responsibility for Protecting Absolute Work Zones As provided in the Construction Coordination Agreement, the Railroad flagger shall render all tracks within an Absolute Work Zone inaccessible to rail-mounted traffic at or beyond the point of connection with live track, so as to avoid inadvertent access into the Absolute Work Zone by the Railroad's trains, engines, cars or other moveable equipment. As limited by the Construction Coordination Agreement and all applicable agreements, should the Railroad be required to enter an Absolute Work Zone with trains, engines, cars or other moveable equipment, the Railroad shall notify and coordinate with the Contractor in advance. 8.1 Construction Activities near Live Tracks When Contractor's work occurs near live track requiring a coordinated stoppage of the Railroad's trains, engines, cars or other moveable equipment and personnel, the Contractor ano the Railroad Representative shall communicate and coordinate to define all safe distances and space needed by the Contractor to perfonn its duties safely. 14 14802924\V-3 EXHIBITCTO ACCESS AND .MAINTENANCE EASEMENT AGREEMENT Section III.R of the Formal Agreement R.

Each Party hereby designates the following senior executive of such Party (the "Designated Executive") and agrees that such Designated Executives shall have full authority to resolve such Dispute. The Designated Executive for UPRR shall be John Hovanec. The Designated Executive for NTTA shall be Rick Herrington. The Designated Executive for the City shall be Bryan Beck. The Designated Executive for TxDOT shall be Maribel Chavez. In the event any Designated Executive is no longer employed by the applicable Party or has undertaken a new position with such Party that does not include responsibilities related to this Formal Agreement, such Party shall designate a replacement, and deliver written notice of such replacement to the other Parties. Ariy Party may also replace its Designated Executive upon written notice to the other Parties. The Designated Executives shall immediately begin to communicate regarding the Dispute, including attendance at a personal meeting if requested by any other Designated Executive, and shall exercise good faith efforts to resolve the Dispute fairly and completely within 30 days from the date of the last Resolution Response Notice. If the Dispute has not been resolved within 30 days of the submission of such Dispute to the Designated Executives (or at any time after such submission, if any Involved Party believes that time is of the essence with respect to such Dispute and that the resolution process should be expedited), then any Involved Party may by written notice to the other Involved Parties refer the Dispute to the Chief Executive Officers (or persons having equivalent decision-making authority regardless of title) of the Involved Parties for their review and resolution. 2 . Non-Binding Mediation. If the applicable Chief Executive Officers do not resolve the Dispute within 20 days of submission to them, then any Involved Party may give written notice to the other Involved Parties of its intent to mediate the Dispute. If the Involved Parties do not agree upon a mediator within 20 days following the other Involved Parties' receipt of the notice of the intent to mediate, any Involved Party may refer the matter to the Austin office of the American Arbitration Association for non-binding mediation. The Designated Executives for the Involved Parties shall attend the mediation m person . The applicable Chief C 148 17 356\V-3 Executive Officers will not be required to attend the mediation in person, but will remain involved in the mediation process to consult with the Designated Executives. Subject to the availability of the mediator, any mediation shall be initiated within 30 days ( or other mutually agreed time period) of the selection of the mediator, and the mediation process must be concluded within 45 days ( or other mutually agreed time period) from the mediation start date. If such mediation is concluded without a resolution to the Dispute that is satisfactory to all of the Involved Parties, (a) if such Dispute is an Arbitrable Dispute, it shall be resolved pursuant to the procedures set forth in subsection III.R.3., or (b) if such Dispute is a Non-Arbitrable Dispute, it shall not be subject to the procedures set forth in such subsection III.R.3., but shall instead be resolved either by a final, non-appealable order of a court of competent jurisdiction or by the subsequent agreement of all of the Involved Parties. Notwithstanding the foregoing, any Dispute (whether an Arbitrable Dispute or a Non-Arbitrable Dispute) in which TxDOT is an Involved Party shall not be subject to the procedures set forth in such subsection III.R.3., but instead the Party asserting the Dispute may seek to resolve the Dispute through either its exercise of any remedy - or means available in law or equity or by the subsequent agreement of all of the Involved Parties. The costs and expenses of mediation, including compensation and expenses of the mediator, but excluding attorneys' fees incurred by any Party, shall be borne 50% by UPRR and 50% by the other Involved Parties, unless such Dispute is between the Project Partners, in which case each Project Partner shall bear an equal share of such costs, compensation and expenses. 3. Final, Exclusive and Binding Arbitration. Any Arbitrable Dispute that is not resolved consistent with the procedures in subsections III.R. l. and 2. and does not include TxDOT as an Involved Party shall be finally resolved by final, exclusive, and binding arbitration under this subsection III.R.3. Judgment upon the award rendered by the arbitral tribunal may be entered in any court havin·g jurisdiction thereof. ( a) The arbitration process will be commenced by the initiating Party giving written notice to the other Involved Parties of its intention to arbitrate such Arbitrable Dispute (the "Arbitration Demand"). The Arbitration Demand specifically shall identify the questions to be submitted for arbitration. The other Involved Parties, within 10 business days after receipt of the Arbitration Demand, shall submit a written response to the initiating Party and the other Involved Parties that specifically responds to the questions identified in the Arbitration Demand and identifies any additional questions (which may include counterclaims or additional claims against the initiating Party arising under this Formal Agreement) to be submitted for arbitration in connection with such Arbitrable Dispute.

C 14 8 17356\V-3 (b) Venue for the arbitration shall be as set out below, unless otherwise mutually agreed by the Involved Parties. Within 20 business days after the Arbitration Demand is made, UPRR shall choose one arbitrator and the Involved Party or Parties that are Project Partners will jointly designate one arbitrator ( collectively, the "party arbitrators") and shall notify the other Involved Parties of such choice. Within 10 days after notice is served of their appointment by such Involved Parties, the two arbitrators so chosen will appoint a third arbitrator (the "Chairperson"). The three arbitrators are hereinafter referred to as the "Arbitration Panel". Disputes which primarily involve interpretations of the scope or nature of the Parties' legal rights and obligations under this Formal Agreement shall be determined by arbitrators who are practicing attorneys or retired judges having at least 10 years experience of involvement in the litigation or arbitration of public or commercial contract disputes. Disputes which primarily involve claims or defenses based on the nature of the construction to be performed pursuant to this Formal Agreement or the facts and circumstances surrounding the execution of such construction shall be determined by arbitrators who have at least IO years experience of involvement in both large-scale rail transportation and large-scale highway transportation projects as either an officer or construction manager at a nationally recognized construction, construction management, or civil engineering firm that has not been employed by any of the Project Partners or UPRR during the past 5 years. If the selecting Involved Parties disagree about the type of arbitrators to be appointed for any Dispute, each such selecting Involved Party shall designate the type of arbitrator it deems appropriate and the party arbitrators shall select a Chairperson of the type they deem appropriate. The Chairperson shall preside over the Arbitration Panel. Any issue presented to the Arbitration Panel shall be decided by two or more of the arbitrators ; provided, however, that in the event two or more panel members cannot reach agreement on any particular issue, the issue shall be decided by the Chairperson. If the two arbitrators so chosen are unable to select a Chairperson as provided above, the Chairperson shall be selected by a Judge of the United States Federal District Court sitting in Austin, upon a petition that forthwith shall he filed by the two arbitrators selected by the Involved Parties. Once the arbitration process has commenced and until it has concluded, the arbitrators shall not communicate ex parte with any of the Involved Parties or their representatives concerning the arbitration. The Arbitration Panel , when complete, shall meet forthwith with the Involved Parties in an initial hearing to discuss procedures and preliminary issues. ( c) At the request of any Involved Party, or at the discretion of the Arbitration Panel, and consistent with the expedited nature of the arbitration procedure set forth in this Formal Agreement, the Arbitration Panel may direct the following discovery: (i) the production of documents and other information; C 148 17356\V-3 (ii) the depositions of select witnesses identified by the Involved Parties; and (iii) answers to written interrogatories or requests for admissions. (d) The Arbitration Panel may, in its discretion, apply the standards of Federal Rule of Civil Procedure 26 in order to resolve any disputes that may arise in connection with these discovery _procedures. In addition, at the request of any Involved Party, the Arbitration Panel may enter such protective orders as are appropriate to protect trade secret, proprietary and confidential information. (e) The discovery and disclosure addressed in this Section IILR. shall be completed within 90 days after the initial hearing. If necessary to compel attendance of witnesses to provide testimony at depositions or at trial or to provide documents, any Involved Party or the Arbitration Panel may petition any court of competent jurisdiction to issue subpoenas compelling discovery. (f) The Arbitration Panel shall, with reasonable diligence (not to exceed 120 days after the initial hearing) conduct an evidentiary hearing, and such other proceedings as they deem appropriate, and complete those proceedings. The evidentiary hearing, and all other hearings, will be held after reasonable notice is given of the time and place to the Involved Parties. At the evidentiary hearing, each Involved Party will be pennitted to present its case, witnesses and evidence, if any, in the presence of the other Involved Parties, and to conduct direct and cross-examination as the Arbitration Panel may decide is appropriate.

V 2 INTRODUCTION 2.1 Project Description HVJ Associates, Inc. was retained by Kimley -Horn and Associates, Inc. to provide geotechnical services for the proposed Water and Sanitary Sewer Relocations within UPRR Yard for SH 121 Tin Fort Worth, Texas . The project involves installation of new water and sanitary sewer lines at UPRR Yard located south of West Vickery Boulevard and west of Hulen Road in Fort Forth, Texas. The purpose of this geotechnical investigation is to provide geotechnical information at the proposed water and sanitary sewer locations . 2.2 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 seventeen 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. 3 FIELD INVESTIGATION 3.1 GeotecbaicaJ Borings The field exploration program undertaken at the project site was performed between May 26 and June 5, 2009 for all the borings excluding borings BH-SA, BH-8A, BH-9A and BH-12A. Borings BH-SA, BH-8A, BH-9A and BH-12A were drilled between September 3 and September 9, 2009 immediately next to the borings BH-5, BH-8, BH-9 and BH-12. These borings were drilled to obtain additional rock samples and to install piezometers . The subsurface conditions were investigated by drilling a total of seventeen borings: four 25-foot borings (BH-1 through BH-3 and BH-6), six 30-foot borings (BH-4, BH-5, BH-SA, BH-7, BH-12A and BH-13), one 35-foot boring (BH-12), two 45-foot borings (BH-11 and BH-14), one SO-foot borings (BH-8A), one 55-foot borings (BH-9A), and two 60-foot borings (BH-8 and BH-9) below the existing grade . It should be noted that due to accessibility issues one of the borings (BH-10) was not drilled. All boreholes were backfilled with soil cuttings except for borings BH-SA and BH-12A. These two borings were converted to piezometers to obtain ground water level readings. A site plan showing the approximate boring locations is presented on the Plan of Borings, Plate 2. 3.2 Sampling Methods Soil samples were obtained continuously to 10 feet and at 5-foot intervals thereafter in all borings except for BH-SA, BH-8A, BH-9A and BH-12A. BH-SA was augered to depth 15 feet, then sampled continuously to depth 30 feet. BH-8A was augered to a depth of 35 feet, then sampled continuously to depth 50 feet. BH-9A was augered to a depth of 40 feet, then sampled continuously 1 to depth 55 feet. BH-12A was auge red to a depth of 15 feet , then sampled continuously to depth 30 feet. Cohesive soil samples were obtained with a three-inch thin-walled (Shelby) tube sampler in general accordance with ASTM D-1587 standard. Granular cohesionless soils were sampled with the Standard Penetration Test (S PT) sampler in accordance with ASTM D1586 standard. 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 p ackaged for transportation to our laboratory. Except for borings BH-8A and BH-9A, 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 m aterials, the cone is 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 3 through 15. In borings BH-8A and BH-9A, continuous coring was performed when rock was encountered. Detailed descriptions of the soils encountered in the borings are given on the boring logs presented on Plates 3 through 19 . A key to the soils classification and sy mbols used in the boring logs is also presented on Plates 20 and 21. 3.3 Water Level Measurements Groundwater levels in the borings were observed during and after completion of drilling. The water levels measured during and after drilling are reported on the boring logs presented on Plates 3 through 19. Two borings were converted into piezometers BH-5A and BH-12A. The 24 hour water re adings were 22.5 feet and 28 feet for borings BH-5A and BH-12A, respectively. The readings taken on November 3<d, 2009 were 14 feet and 17 .5 feet for borings BH-5A and BH-12A, re spectively. 4 LABORATORYTESTING Selected soil samples were te sted in the laboratory to determine applicable physical and engineering properties . All tests were performed ac cording to the relevant ASTM Standards . These tests consisted of moisture content measurements, pocket penetrometer, percent passing No. 200 sieve, sieve analysis, Atterberg Limits, 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. Slake, cerchar, and unconfined compression tests were also conducted on rock samples . The type and number of tests performed for this investigation are summarized below: 2 Type of Test Number of Tests Moisture Content (A STM D2216) 90 Atterberg Limits (ASTM D4318) 21 Percent Passing No. 200 Sieve (ASTM D1140) 24 Hand Penetrometer 55 Unconfined Compression (Soil) (ASTM D 2166) 16 Unconfined Compression (Rock) (ASTM D 2166) 4 Cerchar Abrassiveness 2 Slake Durability (ASTM D 4644) 2 Unit Dry Weight (ASTM D 2166) 16 Sieve analysis test results are presented in Appendix B. The summary of laboratory test results is presented in Appendix B . Slake durability and cerchar abrasiveness test results are presented in Appendix C. 5 SITE CHARACTERIZATION 5.1 General Geology 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 Kiamichi Formation (map symbol Kki) and Duck Creek Formation (map symbol Kdc). The Alluvium and Fluviatile deposits mainly consist of flood-plain deposits including gravel, sand, silt, silty clay, clay and organic matter. The Kiamichi Formation is mainly represented by clay and limestone in alternating units 0 .1 - 5 feet thick and some sandstone. Clay, calcareous, olive brown, weathers yellowish brown, constitutes about two- third of formation. Limestone, mostly aphanitic and bioclastic, locally burrowed, medium gray to yellowish gray. Sandstone, fine grained, moderately well sorted, calcareous, burrowed, beds 0.1 -2 foot thick, medium gray. The Duck Creek Formation consists of limestone, aphanitic and partially bioclastic, locally burrowed, medium gray to yellowish gray and weathers, dark gray with yellowish- brown patches, locally forms topographic benches.

The proposed combined 48 " pipelines have an approximate length of 1,870 linear feet. The proposed combined 42" pipeline has an approximate length of 1,432 linear feet. The proposed combined 36" pipelines have an approximate length of 1,399 linear feet. The selected pipe material is dielectrically coated carbon steel. Upon completion of the corros1v1ty 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 for the combined water pipeline systems . This report presents the results of the corrosivity evaluation and corrosion protection design. 2.0 EXECUTIVE SUMMARY 2.1 Soil characteristics were found to be heterogeneous in the vicinity of the proposed water line alignments . Variations in soil resistivity can promote the formation of concentration cells that lead to corrosion. 2.2 The dielectric bonded coating on the steel pipe is the primary corrosion control mechanism. However, corrosion will occur at those areas where there are coating defects (holidays). The installation of a cathodic protection system is therefore recommended for the dielectrically coated steel pipe to mitigate corrosion at coating defects . 2.3 Joint bonding at all mechanical connections is required for cathodic protection. 2.4 The evaluation indi cates that stray direct currents may be a concern for the pipeline integrity . 2.5 Test stations should be installed at all cathodically protected foreign pipeline crossings , cased 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 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 integrity of the proposed water pipeline. The evaluation performed is the basis for determining the corrosion protection requirements for the City of Fort Worth 48 ", 42", and 36" Diameter Water Line Extensions for the Hulen to Como waterline project pipeline sections W-lA, W- 1B, W-lC and W-lE located in Fort Worth, Texas. 3.2 RESULTS AND ANALYSIS Soil resistivity measurements were recorded at a total of twelve (12) locations, from grade to depths of five feet , five to ten feet and ten to fifteen feet along the proposed right-of-way for the combined 48 ", 42 ", and 36" diameter Hulen to Como Water Lines. 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: Minimum Maximum Average Percent < 1,000 Percent < 2,000 Percent< 3,000 City of Fort Worth, Texas 48", 42" & 36" Diameter Hulen to Como Water Line Proiect Sections A, C, D, and E Soil Resistivity 5-10 Feet 1,992 ohm-cm 13,271 ohm-cm 5,666 ohm-cm 0.0% 16 .7% 33.3% 10-15 Feet 3 ,047 ohm-cm 32,103 ohm-cm 9,353 ohm-cm 0.0% 0.0% 0.0% Percent~ 3 ,000 Percent > 5 ,000 67.3 % 33 .3% City of Fort Worth 100.0% 33 .3% 48" & 36" Diameter Stonegate (Clearfork Main Street) Waterline Project Soil Resistivity 5-10 Feet 10-15 Feet Minimum 2 ,000 ohm-cm 3 ,447 ohm-cm Maximum 10 ,067 ohm-cm 15,464 ohm-cm Average 5 ,515 ohm-cm 10 ,729 ohm-cm Percent < 1,000 0.0 % 0.0% Percent < 2 ,000 0 .0 % 0 .0% Percent < 3 ,000 16 .7% 0 .0% Percent~ 3 ,000 3 3 .3% 50.0% Percent > 5 ,000 16 .7 % 33.3% A total of six (6) soil sampl es were coll ecte d by a geo-technical firm along the pipeline right-of-w ay and w ere t e sted in the laboratory for moisture content, pH, chloride ion concentration, sulfid e ion concentration, conductivity and resistivity. Laboratory test results ar e 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 Considering each of the chemical and electrical soil properties that are tested in the field and the laboratory , gene ral g uidelines 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 3.3 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 corro sion . 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 con sidered 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 transmis sion 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 . CORROSION PROTECTION REQUIREMENTS An analysis of the field data obtained during the survey and of the type of proposed pipe material ( dielectrically coated steel) was considered in determining the requirements for and types of corrosion protection that could be considered for the combined 48 ", 42 " and 36 " Hulen to Como Water Line Projects. Fluctuations in soil resistivity in the area indicate that ferrous materials will be subject to electrochemical corrosion. The dielectric coating on the steel pipe is the pnmary corros10n control mechanism. Corrosion will occur, however, at those areas where there are coating defects. Therefore , the coating must be supplemented with cathodic protection. Electrical continuity along the pipe is required to apply cathodic protection. Therefore , joint bonding is required to maintain electrical continuity at all non- welded pipeline joints. It is necessary to electrically isolate the pipeline at all tie-ins to existing 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 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 these water lines. 4.2 PROTECTIVE COATINGS A polyurethane coating system is recommended to prevent corrosion of the external surfaces of the carbon steel pipeline. The polyurethane coating shall be in accordance with the ANSI/ A WWA 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 & BACKFILL 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 and 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 recommend ed galvanic mag ne si um anode cathodic protection system for the combined City of Fort Worth water line projects are as follows: 48", 42 " and 36 " diameter Hulen to Como Water Line Project cathodic protection system shall consist of a total of eight (8) galvanic magnesium anode ground beds . Each ground bed consisting of 20-pound elongated prepackaged magnesium anodes. Anode ground bed s shall be connected to the pipelines through test stations at pipeline stations as follows: Line W-lA: Pipeline Station 3+30. _ Line W-lB: Pipeline Stations 5+50 , 8+10 , and 12 +9 5. Line W-IC : Pipeline Stations 2+13 and 8+00 . Line W-1 E: Pipeline Stations 1 +9 7 and 15 +60 . Refer to Appendix E for Specifications on Galvanic Anode Cathodic Protection System components and the number of anodes per ground bed. 4.5 JOINT BONDING AND ELECTRICAL ISOLATION The 48 ", 42 " and 36" diameter Hulen to Como water pipelines should be electrically isolated from existing metallic water mains and laterals. However, the three projects shall be electrically continuous with each other. All of the pipelines also require two bonding wires across each non-welded mechanical joint. Refer to Appendix C , Joint Bonding and E lectrical Isolation. 4.6 TEST STA TIO NS Test stations will allow p eriodic 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. Test Station types are as follows: 1. 2. TS -Standard pipe-to-soil potential measurement test station at grounded locations (see TS ty pe test station on the cathodic protection drawings). CC -Test station installed at the ends of metallic pipeline casings with 2 lead wires to the pipeline and 2 lead wires to the cas in g (see CC type tes t stati on on th e cathodic protection d rawings). CC tes t stati ons sha ll be in sta ll ed at both ends of all meta ll ic cas ings. 3. FL -Test statio n in sta ll ed at crossin g of underground , cathodi ca ll y protecte d p iping syste ms own ed by others (foreign pip elin es), (see FL type tes t stat io n on th e cathodic protection draw ings). 4. IF -Test stati on insta ll ed acros s und er ground ele ctrical isolation JO mt s. (see IF ty pe tes t stati on on th e cathodic protection drawi ngs). Note: Lead wires and bond wires are to be install ed on the foreign pipelines by the foreign pip eline owners . The City of Fort Worth will make arrangements with the foreign pipeline owners (if any) for installation of lead wire s and bond wires on the foreign pipelines. Contractor SHALL NOT inst all 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 alignments will provide the means for external corrosion control for the 48", 42 " and 36 " Diameter Hulen to Como Water Line Project. 4 .7 .2 The proposed water pipelines should be electrically isolated from existing metallic transmission mains , laterals and plant facilities, but shall be electrically continuous among the combined three projects. 4 .7.3 Joint bonding at non-welded mechanical connections 1s 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 .

PART 3 -EXECUTION 3.01 INSTALLATION OF ELECTRICAL CONTINUITY BONDS A. Inspection: Use continuous bond wires with no cuts or tears in the insulation covering the conductor. B. General: Attach bond wires or bond straps at required locations by thermite welding process. C. Thermite Welding Methods : Perform thermite welding of bond wires and bond straps to piping in the following manner: 1. Clean and dry pipe to which wires or straps are to be attached. 2. Use grinding wheel to remove all coating, mill scale, oxide, grease, and dirt from an area approximately 3 inches square. Grind surface to bright metal. 3. Remove approximately 1 inch of insulation from each end of wire to be thermite welded to pipe , exposing clean, oxide-free copper for welding. 4. Select proper size thermite weld mold as recommended by manufacturer. Place wire or strap between graphite mold and the prepared metal surface. 5. Place metal disk in bottom of mold . 6. Pour thermite weld charge into the mold . Squeeze bottom of cartridge to spread ignition powder over charge. 7. Close mold cover and ignite starting powder with flint gun. 8. After exothermic reaction, remove thermite weld mold and gently strike weld with a hammer to remove weld slag . Pull on wire or strap to assure a secure connection . If weld is not secure or the bond breaks, repeat procedure with new wire or strap. 9. If weld is secure, coat all bare metal and weld metal with Kop-Coat. Cover coated weld with a plastic weld cap . February, 2010 15640 Page 4 of7 CITY OF FORT WORTH HULEN TO COMO WATERLINE PROJECT JOINT BONDING AND ELECTRICAL ISOLATION D. Post-Installation Inspection: Post-installation inspection of all electrical continuity bonds shall be made through a visual examination of each thermite weld connection for strength and suitable coating prior to backfilling . In addition, perform one or more of the following tests : 1. Circulate current through pipe using DC power supply. Calculate resistance through known le ngth of pipe. Re sistance must not exceed 150% of theoretical resistance for pipe and bonds. 2. Measure resistance throu gh se lect bonded joints with a digital low resistance ohmmeter (DLRO). Resistance of 0.00 I ohms or less is acceptable. 3. Position a copper sulfate reference electrode (CSE) at a stationary location adjacent to bonded pipeline. Impress a temporary current on pipe. Record the static , current-applied and instant off pipe-to-soil potential readings along the pipe relative to a stationary CSE. a. Static potential measurements referenced to a stationary CSE must be nearly identical along the pipe to indicate electrical continuity. b. Instant off potentials referenced to stationary CSE must be nearly identical along pipe to indicate electrical continuity. c. The difference between the instant off and the static potential referenced to a stationary CSE must be equal at each point of contact to pipe to indicate electrical continuity. 4. If any of the above procedures indicates a poor quality bond connection, reinstall the bond. 5. Record results and submit to the owner or its designated representative for approval prior to backfilling. E. Backfilling of Bonded Joints : 1. Perform backfilling of bonded p1pmg in manner that prevents damage to the bonds and all connections to the metallic structures . a. Use appropriate backfill materia l to completely cover the electrical bond. b. Provide protection so that future construction activities in the area will not destroy the bonded connections. 2. If construction activity damages a bonded connection , install new bond wire . February , 2010 15640 Page 5 of7 CITY OF FORT WORTH HULEN TO COMO WATERLINE PROJECT JOINT BONDING AND ELECTRICAL ISOLATION 3.02 INSTALLATION OF FLANGE ISOLATION DEVICES A. Placement: Install isolation joints at all locations where pipe option is tied into other existing metallic piping of different piping material. B. Assembly: Place gasket , sleeves, and washers as recommended by the manufacturer. Follow manufacturer's recommendations for even tightening to proper torque. C. Testing: Immediately after an insulating fitting has been installed , test electrical isolation with a Gas Electronics model 601 meter , or approved equal. Fully document test results. D. Painting: Do not use metal base paints on insulating fittings. E. Encapsulation: Encapsulate below-grade isolation joints with the Carboline Densyl tape system, or approved equal , after the isolation joint has been tested for effectiveness . 3.03 TESTING OF ELECTRICALLY ISOLA TED PIPELINE JOINTS A. General: After the completion of the installation of the flange electrical isolation kits at designated joints, but before the pipe is backfilled, each isolation joint shall be tested for electrical continuity. B. A DC current shall be impressed on the pipe on one side of the joint under test using ~ portable 12-volt battery and a driven ground rod. The battery shall be connected such that the positive terminal is connected to the ground rod and the negative terminal is connected to the pipe section under test. The magnitude of test current is not important as long as it causes a change in pipe-to-soil potential on the section of pipe that is in the test current circuit. C. The pipe-to soil potential shall be measured on each side of the isolation joint using a high impedance voltmeter and portable copper/copper sulfate reference electrode with the test current "on" and "off'. D. A joint is considered electrically continuous if the "on" and "off' potentials are the same on either side of the joint under test. E. This same procedure shall be used to test individual isolation joints except that the joint is considered isolated if the pipe-to-soil potential is not the same when measured on each side of the joint when the test current is "on". 3.04 INSTALLATION OF CASING SPACERS A. Assemble and securely fasten casing spacers to the pipeline to be installed in casings or: tunnels . B. Avoid inadvertent metallic contact between casing and carrier pipe. Place spacers close enough to ensure that the pipe is adequately supported throughout its length, particularly at the ends, to offset settling and possible electrical shorting. The end spacer must be within 6 inches of the end of the casing pipe , regardless of size of casing and pipe or type of spacer used. February, 2010 15640 Page 6 of7 CITY OF FORT WORTH HULEN TO COMO WATERLINE PROJECT JOINT BONDING AND ELECTRICAL ISOLATION C. Grade the bottom o f the tre nch adjacent to each end o f the casing to provide a firm, uniform and continuous supp ort for th e pip e . If th e tr ench requires some backfill to establish the final trench bottom grade , place th e backfill material in 6-inch lifts and compact each layer. D. After the casing or tunn el liner has been pl aced , pump dry and maintain dry until the casing spacers and end seal s are inst all ed . E . Install casing spacers in accordance w ith the manufa cturer's instructions. Correctly assemble, evenly tighten , and prevent damage during tighte ning of the insulators and pipe insertion. F. Insulator Spacing: 1. Maximum distance between spacers to be 10 fe et for pipe sizes 6 inches and smaller, and 6 feet for pipe si ze s greater th a n 6 inches. 2. For ductile-iron pipe , flanged pipe , o r be ll and spi g ot pipe , install spacers within one foot on each side of the bell or fl ange , and on e in the center of the joint where 18 foot or 20 foot long joints are used. 3. If the casing or pipe is angled or bent, reduce the sp acing . . 3.05 INSTALLATION OF END SEALS A. Assemble hard rubber Link-Seals around the pipe and slide into the annular space between the pipe and cas ing. Evenly ti ghte n the bolts to provide a positive seal. B. Place pull-on synthetic rubber end seals on th e pipe and pull o ver the end of the casing. Securely fasten stainless steel bands . 3.06 CASED CROSSING ISOLATION TESTS A. Immediately after the pipe has been insta ll ed in the casing, but prior to connecting the line, perform an electrical continuity te st to d etermine that the casing is electrically isolated from the pipeline. The continuity check shall be fully documented and approved by the owner or its designated repres entati ve prior to backfilling . B.

The process of development with its alteration of natural topography, vegetation and creation of impervious cover can have a negative effect on the ecological balance on an area by causing increases in air temperature and accelerating the processes of runoff, erosion and sedimentation. Recognizing that the general objectives of this section are to promote and protect the health, safety and welfare of the public, it is declared that this section is adopted with the following objectives: 1. Eliminate the process of clear cutting; 2. Promote the preservation/ conservation of trees throughout the city; 3 3. Recognize the benefits of trees in the urban environment; 4. Encourage planting and preservation of quality trees that are suitable to an area; 5. Promote a safe environment that includes trees; 6. Aid in stabilizing the environment's ecological balance by contributing to the processes of air purification, oxygen regeneration, ground-water recharge and storm water runoff retardation, while at the same time aiding in noise, glare, wind and heat abatement ; 7. To provide visual buffering within and between land uses of differing character to alleviate the harshness of urban life; 8. Enhance the beautification of the city; 9. To safeguard and enhance property values and to protect public and private investment ; 10. To conserve energy; 11. To provide habitat for wildlife; and 12. To encourage the preservation oflarge trees which, once removed , can be replaced only after generations. 2. Tree coverage a. The municipal urban forestry strategy is to achieve citywide tree canopy coverage of 30%. To achieve the citywide 30% tree canopy coverage goal, these tree regulations are directed toward preservation, planting and maintenance. b. The citywide 30% canopy coverage goal will be achieved through residential land uses ( one and two family dwelling units) having 40% canopy coverage, commercial land uses having 30% canopy coverage and industrial land uses having 20% canopy coverage. The 40% canopy coverage for one and two family developments will be reduced by 15% canopy coverage if one tree per residential lot is placed on all lots up to 5000 square feet in area and one additional tree for each additional 5000 square feet or faction thereof up to a maximum of nine (9) trees per residential lot. The remaining 25% canopy coverage to be provided in public right of ways , parks, Homeowner Association lots or boundary street parkways. For other residential uses and mixed used areas , 50% of the required open space will have canopy coverage through planting or preservation. c. To achieve the 30% citywide canopy coverage goal, all parking areas for all developments other than one or two family developments shall have a 40% canopy coverage achieved through preservation of existing or tree planting within the parking field and drives. Planting within the parkway will be credited to the coverage requirements. d. Public projects such as city water, sewer or street projects shall have a 30% canopy coverage if the project can not be classified as residential or industrial. City 4 projects that are residential or industrial in nature will be required to meet the canopy coverage for those land uses. 3. Tree preservation / retention of existing canopy a. Preservation of existing canopy coverage regardless of tree type 1. On all properties of land greater than one acre, a minimum retention of existing canopy shall be 25%. The existing canopy can be determined via recent air photo, on the ground survey or other approved method by the City Forester. 2 . Property located in floodplains or located in areas that will be dedicated to public spaces will be counted toward the required 25% minimum retention. 3 . Calculation of all canopy coverage and retention areas will not include utility right of ways or easements covered under the rules and regulation of the Public Utility Commission 4. To remove more than the minimum retention will require a waiver from the Urban Forestry Board. b . Preservation of existing canopy coverage for protected trees only 1. Retention of quality trees (protected trees) only will be allowed if an additional 5% is preserved (a total preservation of 30% of the existing canopy of protected trees) and planting/preservation will ensure an additional 5% coverage (residential coverage would be a minimum of 45%, commercial coverage would be a minimum of 3 5% and industrial would be a minimum of 25%) 2 . To determine the existing tree canopy coverage for protected trees only will require an onsite tree survey noting the location, size( diameter of trees 6 inches or greater) and canopy coverage of each tree. 3. Protected trees include the following species: Redbud Mexi can plum C herry laur e l Eve's neckl ace C rab appl e Brad fo rd pear Golden Ra intree Caddo Maple Red Maple Bigtooth maple Bur oak Chinqu apin oak Ce rcis Canadensis Prunus m exicana Prunus caroliniana Sophora affin is Ma tus ang ustifolia Py rus calleryana var.

Tree preservation / significant or large trees a . Significant or large trees 30 inches in diameter (94.25 inches in ci'rcumference) for the entire city or 20 inch diameter (6 2 .83 inches in circumference) for Post Oaks and Blackjack Oaks east of Interstate Highway 35 West can only be removed by permit of the City Forester . The reduced diameter for Post Oaks and Blackjack Oaks east ofl 35 Wis in recognition of the naturally occurring Post Oak Savannahs w ithin the Cross Timbers Zone . Preservation of a significant or large tree will be credited to the required canopy cover 1.5 times the actual canopy size. b . Criteria for granting the permit will be one of the following conditions ; 1. Removal will be granted if an area 1 Yi times the area of the specific tree 's canopy is retained on the same site . The 1 Yi retention of ex isting trees shall be in excess of the required tree coverage on the site/tract, or 2. Removal will be granted if planting of new trees at five (5) times greater in canopy area than the removed specific tree canopy . The additional planting of 5 to 1 w ill be in ex cess of the required tree coverage on the site , or 3. Payment into the tree fund based upon the total diameter of the specific tree times $200 per diameter inch, or 4. Urban Forestry Board approved plan that mitigates the removal of the large tree c. Replacement any tree preserved and that dies within five years due to construction or development activities will be the responsibility of the original applicant. Replacement will be new trees with a minimum of 3 inches each in diameter and equal to five times the lost canopy. Tree replacement wiLl _ be guarantee for a period of two years. 5. Tree Planting to achieve the goal of canopy coverage 6 a . Trees planting to provide canopy coverage shall be a minimum of 3 inches each in diameter and will be credited its canopy coverage at normal maturity. These credits are as follows: 1. Large canopy tree with typical crown width of 50 feet in diameter - 2000 square feet (minimum spacing of 40 feet on center) 2. Medium canopy tree with typical crown width of30 feet in diameter- 700 square feet (minimum spacing of 24 feet on center) 3. Small canopy tree with typical crown width of 10 feet in diameter-100 square feet (minimum spacing of 8 feet on center) 6. Tree Protections and Maintenance a. All trees being preserved for canopy coverage or a significant tree covered under section 4 due to size will be protected during any development activities. Development activities will include vegetation removal, grading, installation of utilities and/or construction of structures and site amenities. b. Protective measures must occur on all trees located within 50 feet of development activities c. Protective measures are required at the critical root zone (the critical root zone radius is defined as one (1) foot per inch diameter measured at breast height (four and Yi feet) of the tree. d. The following activities within the critical root zone are prohibited: 1. No material intended for use in construction or waste material accumulated due to excavation or demolition shall be place within the limits of the critical root zone of any preserved tree; 2. No equipment shall be cleaned or other liquids deposited or allowed to flow overland with the limits of the critical root zone of a preserved tree .

Procedures required prior to development activities 1. Protective fencing: Prior to development activities, the contractor or subcontractor shall construct and maintain , for each preserved tree or tree cluster on a tract, a protective fence which encircles the outer limits of the critical root zone of the tree to protect it from de velopment activities. All protective fencing shall be in place prior to commencement of any site work and remain in place until all exterior work has been completed. (add minimum requirements on size and material of protective fencing) 2. Bark Protection: In situation where a preserved tree remains in immediate area of intended construction and the City Forester determines the tree bark to be in danger of damage by development activities , the contractor or subcontractor shall protect the tree by enclosing the entire circumference of the tree with 2" x 4" lumber encircled with wire or other means that does not damage the tree. The intent is to protect the bark of the tree against incidental contract by large construction equipment. f. Construction methods 1. Boring: Boring of utilities under preserved trees shall be required in those circumstances where it is not possible to trench around the critical root zone of the preserved tree. When required, the length of the bore shall be the width of the critical root zone at a minimum and shall be a minimum depth of 48 inches. 2.
