Two areas of study will initially proceed concurrently: 1) The Southeast Texas Work Plan will focus on development of facilities to serve the metropolitan area of Houston; and 2) the South -Central Texas Work Plan will evaluate the potential for providing additional water supplies for areas west of Houston, including the metropolitan areas of Corpus Christi and San Antonio. A brief discussion of the study objectives and a description of each task for Phases I and II of the study are included herein. Completion of Phase I will result in a conceptual plan which allocates of future water supplies to those regions which will have the greatest water needs, and considering the timing of those needs. Consideration will be given to currently available ground and surface water supplies, potential new supply facilities, direct inter -basin transfers and the potential availability of water supplies through systems operating agreements among two or more water supply agencies. Phase II will provide a study which illustrates and compares the feasibility of various supply scenarios which satisfy the conceptual plan. Sufficient engineering and environmental information will be provided in Phase II to support initial applications for Texas Water Commission (TWC) permits and other associated state permits for future phases, if such are required. The study will be divided into two phases. Phase I will identify available options, and provide a general assessment of the economic, engineering and environmental advantages and disadvantages of each, so that decisions can be made as to which options should be pursued in more detail in Phase II. The major 3 deliverable from phase I will be an interim report containing a matrix which identifies available options for supplying water to the planning area, summarizes the pros and cons of each, and provides recommendations as to the most feasible alternatives. Alternatives will be classified as short or long term, with estimated times for completion. The policy management committee will provide direction as to which options will be studied in more detail in Phase II. Phase II will examine the options selected during Phase I in more detail and will result in a recommended plan of action for meeting water demands in the planning area. Both near-term and long-term recommendations will be identified, with estimated times for development for each, clearly showing how water needs of the planning area will be met, beginning immediately and continuing over a 50 year planning period. It is intended that one contractor will be selected for both Phase I and Phase II. However, because the size and complexity of Phase II is heavily dependent upon information to be obtained in Phase I, firm fees for Phase I will be negotiated at study inception. In addition, a budget estimate for Phase II fees wiil be included based on the consultant's best estimate of the work necessary to complete Phase II. The Consultant will clearly state the assumptions used to establish the fees for Phase II. At the conclusion of Phase I, after decisions are made as to the number of options to be included in Phase II, fees for Phase II will be adjusted, if the scope is materially different from the previously stated assumptions. Prior to initiation of any subsequent phases, beyond Phase II, the Texas Water Development Board (TWDB) and program sponsors will determine the future direction of the Trans - Texas Water Program. Detailed task elements for future project phases will therefore be determined following completion of Phase II. 4 T T" Is expected that Phase I will be completed within six months of notice to proceed, and that all work for both phases will be completed within eighteen months. A. STUDY OBJECTIVES The selection of individual work tasks and the sequence for task completion for the initial phase is based on a strategy which is a function of several key elements: • The size and phasing of conveyance systems from the Sabine basin to the Houston metropolitan area can be affected by any alternatives identified in this portion of the study that may require transfer of additional water from the Sabine basin to river basins west of Houston as part of a systems operating scheme. Accordingly, this program must be closely coordinated with the Southeast portion of the overall program. ♦ The study will focus on meeting the water resource needs of the Corpus Christi and San Antonio metropolitan areas, in both short and long-term planning periods. While the demands of the Corpus Christi area have been substantially defined, those for the San Antonio region are in a state of flux, and are dependent on the results of Texas Water Commission decisions as to allowable pumpage levels from the Edwards aquifer and the degree to which springflow augmentation can meet environmental requirements. Negotiations on the pumpage levels and a proposed study of springflow augmentation will likely be proceeding concurrently with this study, and will require close coordination. Since results of these two efforts may not be available prior to the conclusion of the present study, alternative values for several parameters, which will encompass the range of likely results from the two studies, will have to be estimated. In addition, definition of demands and available supplies in intervening and downstream areas, 5 for all usage sectors, will be necessary in order to insure that meeting of demands in the targeted growth centers of San Antonio and Corpus Christi will not deprive these other areas and sectors of adequate water supplies to meet their needs. Demands and supplies for these intervening areas will only be established at the county level, using currently available data from the TWDB. Demands will be based on TWDB high case with conservation. ♦ Environmental implications of this project will be significant. There is considerable potential for adverse impacts on both the local and ecosystem scale. Therefore, the overall program strategy involves identifying and investigating issues on those two scales during the initial phases of the work. In -stream flows and inflows to estuaries are important environmental demands on water that must be estimated and incorporated into planning and alternative assessment in phase I. Environmental impacts of structural development must also be incorporated into the initial phases of the work. Minimizing adverse environmental impacts, and where possible, enhancing environmental benefits will be an important focus for phase II of the project. Although this study will not encompass formal environmental reviews as defined by the National Environmental Policy Act (NEPA), general procedures of the federal environmental review processes will be used to ensure that an open, public method is used to document project impacts, and to maximize the usefulness of environmental information in any subsequent NEPA and/or state processes. ♦ Because of its magnitude and complexity, this program will require detailed implementation studies which addresses institutional/legal issues, and environmental and engineering concerns. Debt financing and project scheduling issues will need to be developed fully within the implementation studies. 6 _t Successful completion of a regional project of this type requires that a range of project feasibility issues be resolved to satisfy potential participants of the integrity of the project. The implementation studies should provide information which assist the sponsors in assessing project feasibility. B. AVAILABLE PLANNING DATA There are a number of planning reports for the south-central planning area available. Some are regional studies sponsored by the TWDB. Others were prepared by the cities of San Antonio and Corpus Christi, the Lavaca-Navidad, Guadalupe -Blanco and Nueces River Authorities, the Edwards Underground Water District and others. It will be the responsibility of the selected consultant to research and analyze these existing studies to glean as much relevant material as possible. Results of a survey of the major river authorities regarding available supplies, reservoir yields, existing contracts and inter -basin transfers will be made available to the selected consultant by the Texas Water Development Board. It is anticipated that significant additional research, data acquisition and modeling on these subjects will also be required. It is expected that TWDB planning data on population and water demands, supplemented by local information where appropriate, will be used to project future water needs of the various areas and usage sectors. TWDB demands for high population projections, with conservation will be used. C. ENVIRONMENTAL ISSUES An environmental analysis will initially be developed which will provide information on the planning, environmental, and engineering aspects of the project. Information initially obtained in the environmental analysis will influence each aspect of the project. Initial planning study information will be included in the analysis, and applications for amendment to the TWC water rights permit, if required, will be based on the information developed in 7 the environmental analysis. This information will also be used in to facilitate continuing negotiations between the City Of San Antonio and the Texas Water Commission, regarding water rights and the Edwards Underground River. To acquire federal permits, and potentially state permits, a more detailed environmental study will be prepared, in future study phases. Final project design will be a result of either a formal environmental assessment or environmental impact statement. Therefore, in order to minimize duplication of effort, the National Environmental Policy Act (NEPA) process will be followed to the greatest extent possible in Phases I and II. The type of federal environmental permit(s) pursued should be determined. Determination of the appropriate process will be a function of the viability of the entire Trans -Texas Program, the viability of the Southeast and South -Central Projects, and the type of potential environmental impacts. D. IMPLEMENTATION ISSUES As a part of project development, implementation studies are proposed to provide necessary details regarding a number of important issues. These issues include: ♦ institutional/Legal factors created by the requirements of the proposed project or action and by the need for long term contracts regarding facility usage and debt retirement. ♦ Financial/Cost considerations of the proposed plan including financing alternatives and the resulting pricing requirements for users of the water. A comparative cost of alternatives will be calculated and presented, where appropriate. ♦ Schedule/Phasing considerations for implementing the 8 preconstruction and construction phases, including staging options for construction. Consideration shall be given to the need for scheduling projects to meet both short- and long-term water needs of the planning area. Each issue will require evaluation and input by project participants. The goal of the implementation studies is to establish strategies which address participant concerns and establishes a realistic schedule of critical events necessary to accomplish program goals. Refinement of the implementation plan will be required as each program phase progresses. V Two distinct phases of activity are included in the Work Plan for this program. A brief overview of each of these phases is provided below: ♦ Phase I - Conceptual Plan Preparation ♦ Phase II - Feasibility Studies Phase I - Conceptual Plan Preparation Several different studies have been conducted to identify and evaluate alternatives for supplying water to the targeted study area. Therefore, this initial phase of work will compile the results of the previous studies, coordinate with the on-going southeast study and update the costs and other appropriate factors identified in these studies. In addition, new concepts for water supply will be developed and included with the previous proposals to establish a summary "conceptual" plan identifying the range of possible inter -basin transfers and local projects necessary to meet the short- and long-range needs of the areas. A plan synopsis will be prepared for distribution to all interested parties illustrating 9 potential conveyance and storage facility sites and features, environmental issues to be addressed, and order -of -magnitude costs for the various alternatives. One of the alternatives to be included in the conceptual plan will consist of a water rights/supply transfer plan. This alternative will consists of allocating water rights to optimize efficiency of delivery through a system operations approach using appropriate contractual arrangements between various suppliers and users. Particular emphasis will be placed on analysis of water rights within the basins and on available supplies near the demand centers. Major water user categories (municipal, industrial, etc.) will be defined as a part of this process. Phase II - Feasibility Studies This phase will investigate in greater detail the engineering, environmental and institutional components of the various scenarios capable of supplying the water needed within the study area. Coordination meetings with state and local agencies will be held to allow review of the proposed program and to discuss issues and concerns of each group. A primary component of this phase is completion of an environmental assessment which can be used as a basis to request TWC permit amendments, if required. The environmental assessment will evaluate the engineering and environmental impacts of the various alternatives. Preferred options which are the most viable alternatives will be identified. This phase culminates in the development of a "Preliminary Implementation Plan." The goal of that plan is to provide an initial schedule and comprehensive list of activities for the remainder of the program and to establish costs and legal/institutional issues with enough detail to allow potential participants to make decisions as to whether or not to proceed with permit requests and /or construction. Some of the important issues 10 to be resolved during this phase include: ♦ Goals, objectives, and concerns of all major potential participants. ♦ Service area/water customers for the new water supplies required. ♦ Availability of groundwater and availability of water rights associated with surface waters planned to meet the projected demands. • Treatability and water quality concerns of the available supplies. ♦ Feasible routes, component sizing, phasing options, etc. to achieve the proposed objectives. ♦ Environmental conveyance and project. • Advantages and facilities. issues and impacts associated with any storage alternatives and with the overall disadvantages of using existing available ♦ Initial construction and operational cost estimates. • Legal/institutional issues. ♦ Debt financing and pricing alternatives available to the participants. ♦ Schedule/phasing considerations, both before and after construction. 11 ♦ Ownership and operational issues to be considered by the participants. ♦ Cost estimates of preferred alternatives. Future Phases The following phases are dependent on the results of the first two phases, and are described here only to better define the preceding phases. They will not be a part of this study. Phase III - Preliminary Design/State and Federal Permitting During this phase, the preferred alternatives will be further analyzed and a final alternative selection process will be accomplished. Issues which were initially identified in Phase II will be thoroughly analyzed during Phase III. A detailed environmental information document will be completed and submitted to the Texas Water Commission and appropriate Federal agencies. Remaining regulatory permits and institutional/agency contracts can also be developed. Finally, a detailed implementation plan will be developed. Phase IV - Property Acguisition/Final Design This phase incudes two major elements: property acquisition and final design. Property Acquisition will include survey and property owner description services and, if necessary, professional and technical assistance during property negotiations and acquisition. Final Design includes survey and geotechnical services, final engineering design, preparation of detailed plans and specifications, and contract documents for construction purposes. 12 Phase V - Erolect Construction. Start -Un and Overation This phase consists of assistance during the bid phase and construction management services during the construction phase of the project. Also included are initial start-up and operational services during the first year of service. A. PHAGE I - CONCEPTUAL PLAN PREPARATION Phase I of the Work Plan includes the following major elements: ♦ Data collection ♦ Identification of alternatives 1. PLANNING AREA The planning area for this study will encompass the lower portions of the Brazos, Colorado, Lavaca, Navidad, Guadalupe, San Antonio and Nueces River basins, generally south and east of a line extending from Houston to San Antonio to Corpus Christi, but including the San Antonio and Corpus Christi metropolitan areas. Attachment "A" shows the planning area. The primary focus of the study will be meeting the needs of the primary demand centers of San Antonio and Corpus Christi, but the needs and available supplies for the remainder of the planning area will need to be quantified. One of the major elements to be addressed will be the inter -basin availability of water through systems operating agreements among the river authorities. Accordingly, it will be necessary to establish demands and supply availabilities for the entire river basins, to the extent that such data may impact lower basin supplies. 13 2. DATA COLLECTION a. Water Demands. Rights and Supplies Collect information from the TWDB regarding the location and nature quantity, quality requirements, etc.) of existing and projected water demand. Assess demand on a county level within each river basin (municipal, industrial, agricultural, and irrigation). Identify the demand centers within each basin. Collect and summarize information from the TWDB and TWC on firm supplies and on adjudicated rights for water in the Brazos, Colorado, Lavaca, Navidad, Guadalupe, San Antonio and Nueces basins. Include general assessments of the quality of the potential supplies and the locations within each basin where such supplies are likely to be available. b. Conveyance Studies Collect information from relevant existing planning and engineering studies regarding any feasible routes, costs, and impacts for various conveyance facilities. c. Existing Facilities Collect information for existing conveyance facilities which could be used to meet water transfer needs in the South -Central planning area. Information to be collected includes ownership, condition, capacity, and availability for alternative uses. d. Proposed Facilities Using the TWDB 1990 Water Plan and other relevant planning studies, collect information on costs, capacities and impacts for various conservation and re -use scenarios, reservoirs, and recharge dams which have been proposed to serve the water needs within the basins included in the study area. New options which have potential for 14 meeting water demands, including inter -basin transfers and systems operating agreements, should also be identified and included in the analysis. 3. IDENTIFICATION OF ALTERNATIVES Feasible alternatives for supplying the identified water demands with available ground and surface water will be illustrated and then compiled for inclusion in the conceptual plan. Capacity and cost data (capital and operations and maintenance) will be updated to reflect present day conditions and the probable extent of potential environmental impacts for each alternative will be identified, along with estimated mitigation costs. 4. DRAFT REPORT PREPARATION At the end of Phase I, a draft report will be prepared summarizing the data collected and alternatives identified. An overall conceptual summary of options will be prepared as a starting point for consideration in Phase II of the program. Review meetings to discuss the alternatives and make modifications as appropriate to reflect the project sponsor input will be conducted as required. B. PEASE II_- FEASIBILITY STUDIES Phase II of the Work Plan includes the following major elements: ♦ Agency/Public Coordination • Planning Studies • Environmental Analysis • Preliminary Implementation Studies 15 r ♦ Draft and final report preparation and coordination A brief description of each work plan element is discussed below. 1. AGENCY/PUBLIC COORDINATION a. Sponsor Meetinas Meet regularly with the City of Corpus Christi, City of San Antonio, Lavaca-Navidad River Authority, Texas Water Development Board, the Texas Water Commission, the Texas Parks and Wildlife Department and other sponsors, if any, to discuss the approach, major issues, design considerations, fiscal issues and permit requirements. b. Agency Meetings Meet with the San Antonio, Guadalupe -Blanco, Brazos, Lower Colorado and Nueces River Authorities and other appropriate federal, state, and local agencies to discuss the study and elicit questions, comments, and concerns. c. Meeting Records Record the content of the agency meetings to chronicle agency coordination efforts. d. Policy Management Committee Assist the program sponsors and the TWDB to establish and coordinate a Policy Management Committee (PMC) representing the TWDB, Texas Water Commission, Texas Parks and Wildlife Department and program sponsors. The PMC will meet monthly to coordinate administrative, technical, and informational matters associated 16 with the study, approve study parameters and approve draft and final reports. The PMC will also meet periodically with sponsors of the eastern study to coordinate between the east and south-central portions of the trans Texas water program. Subcommittees, which will include representation from technical and environmental organizations, will be established by the PMC to provide technical advice and assist the PMC in analyzing study issues. Technical and other advisory committees will be organized on a subject matter and/or geographic basis, and will be the primary avenues for public input into the planning process. Technical and other advisory committees will hold regular public meetings to receive public input, discuss issues and formulate recommendations to the PMC on environmental, financial and engineering issues. Periodic joint meetings with the PMC will also be scheduled. It is intended that the South -Central Texas Water Resources Planning Council, recently established by the TWC, will serve as an advisory committee to the Policy Management Committee, so that recommendations resulting from the Council's activities may be included in the program resulting from this study. 2. PLANNING STUDIES a. Water Demands Existing and future municipal, industrial, agricultural and irrigation water demands will be determined for the year 2040, using TWDB projections for high population growth, with conservation. Environmental demands for in -stream flows and bay and estuary needs will be estimated using simplified assumptions to be coordinated with the TPWD, TWC and TWDB. The resulting demands for environmental purposes shall be considered , along with the TWDB demand projections, in determining availability of water from streams and reservoirs. Assess the impact of conservation measures and re -use on the projected water demands, instream flows, water rights and return flows for bays and estuaries. Determine measures 17 7 necessary to achieve conservation reductions. b. Available Supplies Acquire data on existing and planned ground and surface water supplies available to meet water demands in the individual river basins and the demand centers. Analyze existing water rights in the Lavaca-Navidad, San Antonio, Guadalupe -Blanco, lower Brazos, Lower Colorado and Nueces River Basins. Develop potential systems operations schemes for supplying water to the demand centers in the study area, considering current, as well as future availability. Based on this information, determine the quantities of water required to meet projected unserved water needs in these basins. c. Water Duality Acquire existing water quality data for groundwater and water from rivers which might be mixed with the water from other rivers. Suitability of potential water supplies for displacement of, or exchange between usage categories, such as irrigation and municipal, will be assessed. Review existing surface water treatment processes in the intended service areas and develop preliminary conceptual designs and costs for modifications needed to treat groundwater, surface water or mixed waters. 3. ENVIRONNANTAL ANALYSIS a. Meetings Assist the Lavaca-Navidad River Authority plan and conduct coordination meetings on environmental issues. Meetings will be held with local, state, and federal governmental agencies and public interest groups in the environmental community. r 18 b. Environmental Baseline Review previous studies of water delivery to demand centers in the study area, and note alternate routes. Collect and review all pertinent existing environmental data. Use available information to identify potential environmental concerns along potential routes. c. Environmental Impacts Prepare an environmental analysis report which contains information on known or potential environmental impacts resulting from the identified alternatives. Alternate water supply options, including conveyance routes, will be studied and the preferred options will be identified. This report may be used to support a TWC water rights amendment application. This analysis will contain: ♦ Project purpose and needs ♦ Conceptual conveyance route engineering design ♦ Environmental impacts analysis of aquatic and terrestrial impacts, to include negative and positive impacts on wetlands, in -stream flow maintenance, bay and estuary salinity gradients, fish, wildlife and water quality. ♦ Conveyance alternatives screening analysis ♦ Cost estimates for environmental enhancements and mitigation, including both capital and operation and maintenance costs. 19 4. PRELIMINARY IMPLEMENTATION STUDIES a. Institutional and Legal Issues Evaluate institutional and legal issues likely to arise, including the following: ♦ Water rights issues ♦ Construction -related legal requirements Environmental and regulatory permits Utility and construction easements Land and right-of-way acquisition ♦ Long-term contractual requirements Water purchase agreements Existing facility usage agreements Operation and maintenance agreements b. Financina and Cost Issues Based on the preliminary estimate of capital costs previously developed, make a more detailed evaluation of costs for the preferred alternative. This evaluation will include the following: ♦ Preliminary financing plan ♦ Estimate of operation and maintenance costs ♦ Pricing policies for water supplies resulting from alternatives. c. Scheduling and Phasina Issues Develop an overall schedule for the project, including the 20 following: ♦ TWC permit application ♦ Options for project phasing ♦ Preconstruction schedule ♦ Construction schedule 5. REPORT PREPARATION AND COORDINATION At the completion of Phase II, the draft report prepared in Phase I will be revised as needed, and expanded to reflect the additional analysis performed during Phase II. Summaries of alternatives evaluated, relative costs and benefits of each, and a recommended alternative or group of alternatives will be presented. A final draft will be prepared and coordinated with sponsors and advisors, prior to final publication of the final report. 25 copies of the final report will be provided. 6. SCHEDULE FOR COMPLETION Work under phase I should be completed approximately 180 days after notice to proceed. Phase II should be completed approximately 240 days after notice to proceed. Attachment "B" is a tentative schedule for the study. 21
