Schedule City Approval of Professional Services Agreement: Notice to Proceed Review of Existing Information and Inspection: Within 14 days after NTP Draft Report to City for Review: Within 60 days after NTP Final Report to City: 10 days after receipt of comments Task 2 — Jim Bertram Lake System, Dam 6 Breach Analysis f COMPLETED) Background HDR Engineering, Inc. (HDR) previously performed dam breach analyses of Dams 2 and 3 of the Jim Bertram Lake System on behalf of the City of Lubbock (City). The City has requested that HDR perform a breach analysis of Dam 6 with the purpose of evaluation of inundation at the City's Southeast Water Reclamation Plant (SWRP) but also with the goal of including the results in a revised Emergency Action Plan. Project Scope of Work To accomplish the Project purpose and goal, the following subtasks will be completed. The definition of Project in this scope of work is performance of a breach analysis of Dam 6. Subtask 1. Project Management, QA/QC, and Communication 1. Provide management of HDR resources to meet the technical, financial, and schedule requirements of the Project. This will include the overall management of the Project and the specialized discipline team(s) responsible for the development of the Project. 2. Project administration and quality assurance/quality control (QA/QC) activities will be performed under this task. Meetings between the City and HDR staff over the course of the work are not anticipated. The results of the analysis could be included in the presentation to the LWAC under Task 1. Subtask 2. Dam Breach Analysis 1. Data collection. HDR will review as -built plans of the dam, reservoir stage -storage - discharge curves and topographic data (LiDAR data) of the area downstream of the dam (USGS, 2018). 2. Perform dam breach analysis using an empirical equation in accordance with the "Simplified Method" of the TCEQ Hydrologic and Hydraulic Guidelines for Dams in Texas (January 2007). A 1-dimensional steady-state hydraulic model will be developed using the computer program HEC-RAS using the LiDAR data from the toe of the dam to a distance dictated by TCEQ guidelines. Roughness coefficients will be assigned to the model geometry based on readily available aerial imagery. A peak dam breach discharge will be applied at the upstream end of the model (at the dam) and attenuation will be modeled downstream. 3. Preparation of a dam breach inundation map. The breach inundation boundary from the HEC-RAS analysis will be exported into a GIS shapefile. Post -processing of the shapefile will be performed to remove inconsistencies. Dam breach inundation maps, including depths Amendment No. 1 — HDR Dam Inspection & Evaluation Services of inundation at key locations determined by HDR as well as at the SWRP, will be developed. These maps could be included in an Emergency Action Plan to be prepared by the City. 4. A technical memorandum will be prepared presenting the results of the analysis, the inundation maps, as well as a description of the methodologies used in the analysis. The memorandum will be presented to the City in draft format (Word doc) for review and comment. Following discussion and resolution of comments, via teleconference or email exchange, the memorandum will be finalized and submitted to the City in portable document format (pdf). Deliverable As described above, the results of Subtask 2 will be documented in a technical report, submitted as a draft (Word doc) for review by the City. The HDR Team will respond to comments and prepare a final technical report within ten business days of receiving the City's comments. The final technical report will be delivered in pdf. Schedule City Approval of Professional Services Agreement: Notice to Proceed Review of Existing Information and Inspection: Within 14 days after NTP Draft Report to City for Review: Within 60 days after NTP Final Report to City: 10 days after receipt of comments. Task 3 - John T. Montford Dam Surveillance and Monitoring Plan Background The City of Lubbock (City) has requested HDR Engineering, Inc. (HDR) to prepare a Surveillance and Monitoring Plan (SMP) that documents current procedures and, where applicable, provides refinements for periodic inspections of John T. Montford Dam (dam) by City personnel, monitoring of existing instrumentation, reduction and evaluation of instrumentation data, and storage of inspection and monitoring records in the City's filing system. The SMP will be developed such that it could be incorporated into an overall operating plan for the dam. Project Scope of Work The project scope of work consists of developing an SMP for the dam that documents procedures for (1) observations to be made of the dam with respect to dam safety, (2) reading of existing instrumentation and evaluation of data, and (3) reporting and long-term storage of observations and monitoring data. To accomplish the project purpose, the following subtasks will be performed. Subtask 1. Interview Staff — Process Flow HDR will interview City staff via phone or remote conferencing to gather relevant information. Anticipated interviews include the dam tender and those in the Water Engineering department that receive data from the field. The purpose of these interviews will be to determine existing procedures in place for data collection, reduction, review, and archival/storage and to identify Amendment No. 1 — HDR Dam Inspection & Evaluation Services 6 existing instrumentation data available in the City files (spreadsheets and/or other electronic data pertaining to the slope inclinometers and tilt meters). Required from the City: The City will identify key staff and assist HDR in scheduling the interviews. Deliverable: HDR will prepare a summary of notes taken during the interviews. Assumptions: HDR anticipates multiple interviews not exceeding 3 hours in total length. Subtask 2. Assemble Instrumentation Information HDR will prepare a data request identifying the types of information required. After receipt of the information from the City, HDR will organize information regarding existing instrumentation (plans, equipment related to instrumentation, and software related to instrumentation). This information will be used to establish an inventory of the instrumentation currently available, and document those instruments that no longer function. Required from the City: The City will provide copies of the information required or will otherwise provide the necessary access of the information to HDR. Deliverable: HDR will include the assembled information as one or more appendices in the plan. Subtask 3. Establish Threshold and Action Levels HDR will review historical data and provide revisions to existing spreadsheet formats to include plots of readings vs. time and threshold and action levels. Threshold and action levels will be based on historical readings, including statistical analyses as appropriate, and design values used in the design of the dam. HDR may recommend other modifications of the data presentation to accommodate the surveillance and monitoring plan. Required from the City: The City will provide digital copies of available spreadsheets or other electronic files containing historical monitoring data from the dam. The City will also provide HDR with a copy of the Design Report for the dam. Deliverable: HDR will provide revised spreadsheets to facilitate ongoing surveillance and monitoring, and archival of the data. Subtask 4. Develop the Surveillance and Monitoring Plan HDR will utilize the information from Subtasks 1, 2 and 3 to develop an SMP for the John T. Montford Dam (see outline attached to this Scope of Work). HDR will submit the SMP in draft form for review and comment, followed by comment resolution and finalization of the SMP. The SMP will consist of three sections, detailed below, and appendices containing inspection forms and details of instrumentation. The SMP will be completed in accordance with current dam safety guidelines including those promulgated by the Texas Commission on Environmental Quality Dam Safety Program. Required from the City: The City will provide timely review and comments on the draft SMP, including compiling and reconciling comments from City staff into a single document. Deliverable: HDR will provide a draft SMP in Word format for review by the City (using track changes) and a final copy of the SMP in PDF format. No hard copies will be provided. Assumptions: The City will provide electronic copies of inspection checklists currently used by City personnel. Review by City of draft will take no longer than 3 weeks.
