The City will collect comments on draft deliverables from City and Northern Water staff and submit a single consolidated set of comments to the Consultant. Task 1.1 – Project Management Plan The Consultant will prepare a Project Management Plan (PMP) with the technical scope, budget, schedule, deliverables, and roles and responsibilities of Fort Collins, Northern Water, and the Consultant team. The PMP will include a project schedule in Primavera P6. P6 allows the development of a time-based budget of costs to be incurred versus time elapsed. The Consultant will track project performance versus cost and schedule on at least a monthly basis. Task 1.2 – Meetings The Consultant will conduct a kick-off meeting and up to 4 monthly progress meetings with the Utilities/Northern Water project management team. Based on their timing related to other project activities (e.g., technical workshops), monthly progress meetings may be conducted in person or via conference call. They are anticipated to last about one hour and will cover recent project activities, upcoming activities, and issues needing resolution. The kick-off meeting will be an approximately 2 hour meeting attended by key Consultant staff; it will include a discussion of the draft PMP and assure there is agreement on lines of communication, project assumptions, and roles and responsibilities. Task 1.3 – Monthly Progress Reports and Invoices The Consultant will submit up to 4 monthly progress reports accompanying monthly invoices. The progress reports will briefly document work performed during the past month, work anticipated in the coming month, and a summary of the budget status. Task 1.4 – Subcontractor Management The Consultant will manage its three subcontractors using accepted project management principles. Subcontractors will be responsible for assigning adequate resources to the project; DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381 managing against their scopes, budgets and schedules; and assuring quality of deliverables and work performed. The Consultant will incorporate subcontractor costs and progress into its monthly progress reports. Task 2 - Background and Literature Review Objective: Collect background information on Fort Collins’ water resources system (facilities, operations, water rights, etc.) and past climate change studies. Agree on the analytical approach for developing future hydrology under climate change assumptions. DELIVERABLES:  Notes from Workshop #1 – Information Transfer: summary of the information collected and the assumptions and tools to be used in the vulnerability analysis  Technical Memorandum (TM) #1 – Climate Change Literature Review: summary of the results of the climate change literature review  Notes from Workshop#2 – Hydrologic Analysis Options: summary of discussion of future hydrology options and input to finalize the future hydrology approach for the study  TM #2 - Final Hydrologic Analysis Approach: summary of the adopted approach for generating climate change-induced hydrologic scenarios and implementation requirements for the vulnerability analysis Task 2.1 – Background Information Transfer The Consultant will conduct a workshop and a review meeting to assimilate background information from Utilities and Northern Water that is relevant to the execution of this project. Workshop #1 – Information Transfer. Utilities and Northern Water staff will present and discuss identified topics that the Consultant feels it needs more information on. The workshop will cover the following topics:  Current population growth and demand projection methods  Current water supply sources and infrastructure  Current demand-side management strategies  Current water supply plans and strategies  Comparable studies prepared for other regional providers  Existing Northern Water tools to evaluate the CBT quota in future scenarios  Current performance of water supply service metrics, level of service policies, and operation decision thresholds This workshop will be a half day meeting, with presentations and discussion of approaches, assumptions and key information to be embedded or revised for the vulnerability study. The project manager and technical leads will attend the workshop and will summarize and share the DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381 results with the rest of the team. Utilities and Northern Water will provide presentations with information, tools, and assumptions for the selected topics at the workshop, and provide relevant documents and reports. Model Review Meeting: The Consultant will conduct a two-hour meeting to review ongoing Fort Collins modeling efforts, current and historical operations, water supply portfolios, water rights, and storage acquisition. The review meeting will be used to gather feedback on the new modeling system and discuss expectations and recent updates on these topics relevant to this project. This review meeting will be attended by Consultant Technical Leads and modeling staff. Task 2.2 – Climate Change Literature Review The Consultant will consider two overarching approaches to represent future hydrologic conditions in the Water Vulnerability Study. The first is a top-down approach that uses a set of representative predictions of temperature and precipitation changes simulated by the Global Circulation Models (GCMs). The second is a bottom-up approach that evaluates performance for estimated hydrologic conditions based on potential combinations of precipitation and temperature changes, allowing identification of future climates for which water system performance is unsatisfactory. The Consultant will conduct a Literature Review to investigate past examples of both approaches to support adoption of an approach for this project. The Consultant will focus the literature review on: 1) recent studies with methods and techniques to consider climate change in municipal water supply planning, and 2) availability of existing tools and data in the study area that are candidates to be adopted for this study. The goal of the review will be to complement and expand the experience and techniques used in the past and inform the approach selection with available tools and data. As a minimum the Consultant will consider the following sources of information, data, and models to support development of the climate change approach to represent future climate conditions for this study. EPA CREAT CREAT is the US Environmental Protection Agency’s (EPA) Climate Resilience Evaluation and Awareness Tool. It provides a generalized framework for water utilities’ risk assessment and climate resiliency planning. Joint Front Range Climate Change Vulnerability Study (JFRCCVS) The JFRCCVS provides sets of climate-adjusted streamflow sequences representing the impact of selected future climate projections on undepleted streamflow volumes. This study has analysis points in the study area, including the Cache la Poudre River, the Big Thompson River, and the Colorado River. The points evaluated are representative, and will need additional analyses or data processing for detailed application in this vulnerability analysis. Colorado River Water Availability Study (CRWAS) The CRWAS was led by the Colorado Water Conservation Board to estimate Colorado River water availability. The study projected DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381 how much water from the Colorado River Basin System will be available to meet Colorado’s future water needs under alternate hydrologies. West-Wide Climate Risk Assessment, U.S. Bureau of Reclamation WWCRA provides downscaled climate and hydrology projections with flexible spatial resolution over the contiguous US. This can be used to estimate streamflow for individual GCM projections. The above sources will suggest methods and preprocessed data to simplify the large GCM datasets and generate predictions to represent future conditions. The Consultant will evaluate their applicability to this study, summarizing the pros and cons to support the development of the final study approach. The Consultant will consider assumptions, methods, tools, and information available in the evaluation. The Consultant will prepare Technical Memorandum (TM) #1 – Climate Change Literature Review to summarize the results of the literature review for review by the City and Northern Water. Workshop #2 – The Consultant will work with Utilities and Northern Water to evaluate options and develop the approach for modeling future hydrologic scenarios based on the data and model availability review findings. The Consultant will conduct a workshop to review the findings, the pros and cons of alternatives, and the proposed approach. The Consultant will finalize the future hydrology modeling approach that will include a method to select a set of future conditions and to calculate the estimated streamflow at key locations in both the Poudre and Colorado Rivers for the PBN model and the C-BT system. The approach also will include requirements for incorporating modified hydrology in the new data-centered modeling system (Task 5) and the scenario development process (Task 6). The Consultant will prepare TM #2 - Final Hydrologic Analysis Approach to document the adopted climate change and hydrologic analysis methods, approaches and assumptions. Task 3 – Future Water Demand Considerations Objective: Develop a GIS-based method of estimating future water demand based on land use characteristics, and apply that method to estimate future water demands under a range of possible future conditions. DELIVERABLES:  Notes from Workshop #3 – Water Demand Drivers and Methods: summary of workshop on factors affecting water demand and potential methods of estimating future demands from land use characteristics  TM #3 – Future Water Demand Estimating Methods: summary of 1) the information to be considered in the demand analysis; 2) the assumptions and drivers to be used in the demand analysis; and 3) documentation on how to use the demand estimating tool DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381  Water Demand GIS Database and Estimation Tool: a GIS-based tool and custom GUI, integrated with the modeling system DMS, capable of generating demand scenarios under various criteria, including geographic region, land use conditions, climate scenarios, and other potential future conditions The Consultant will adopt a spatially-based approach to estimate future water demands that is flexible at incorporating changes in demand assumptions that are difficult to capture with regression-type approaches. This will be conducted in two phases. Phase 1 will consist of all the activities to develop a GIS-centered demand estimation tool (Tasks 3.1through 3.4). Phase 2 will consist of applying the tool to specified future conditions developed as a result of the risk and uncertainty identification process in Task 4 (Task 3.5). Task 3.1 - Water Demand GIS Database The Consultant will develop a GIS-based database and data to provide the foundation for evaluating future water demand. The Consultant will work with Utilities and other related agencies to collect existing base data that will be used to estimate future water demand. Base data will include parcel boundaries, management boundaries (i.e., the city limit, utilities service area, and Growth Management Area [GMA]), zoning, population projections, growth projections, and per capita water use, as well as other necessary data. The Consultant will combine current estimates of outdoor water consumption with remotely sensed methods at the parcel scale to establish the baseline outdoor consumption. This method will include collecting recent (i.e., 2017 if available) 0.5-meter resolution 4-band satellite imagery, using the current city parcels geometry as-is, without ground-truthing, to determine irrigated areas based on the Normalized Difference Vegetation Index (NDVI) without separating grasses from trees. Although this basic spatial representation could be refined to improve estimates of water consumption throughout the City, it provides the foundation and flexibility needed for the vulnerability analysis. By mapping individual parcel irrigation use, actual irrigation information can be linked with other information and assumptions to represent future demand scenarios. The water demand GIS database will help define the relationship between information on water demand drivers and parcel characteristics, apply changes and adjustments for future conditions, and ultimately estimate the total demand by aggregating the parcel information. The database will provide a method for future data to be both updated and included by Utilities staff. Subsequent tasks for framework buildout and the demand tool interface will directly use the database for building demand scenarios and calculating water demand. Task 3.2 – Demand Drivers and Methods Workshop Workshop #3 – The Consultant will conduct a half-day workshop with both Utilities and Northern Water staff to identify specific drivers and methods to represent future water demand. Methods will include rules and assumptions to adjust water demand predictions using various data, including:  Growth projections  Population forecasts  Outdoor irrigation areas, water requirements (hotter climate), and consumption projections  Adoption of xeriscaping DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381  Redevelopment, land use, and zoning  Residential water use efficiencies  Local rainwater use  Reuse/gray-water systems  Conservation effectiveness  Economic conditions and industrial water demand The GIS and database information will provide detailed information regarding the parcels’ current and past water demand, providing local characteristics and trends that can be used to inform assumptions for the methods. With input from the workshop, the Consultant will document the methods, drivers and assumptions to be used in developing an evaluation framework as described in Task 3.3. Task 3.3 – Demand Framework Development The Consultant will integrate the water demand GIS database with future water demand estimation methods, defined in Task 3.2, to create a framework for estimating future water demand scenarios at the parcel scale. The framework will consist of procedures and processes to attach information and apply assumptions to georeferenced parcel polygons based on criteria defined in the method. The framework will result in a master relational database with functionality to generate total water demand for different spatial areas (i.e., the city limits, Utilities service area, and GMA), future conditions, and specific risks or uncertainties. This approach will enable application of complex criteria to create future water demand scenarios. Task 3.4 – Demand Estimation Tool and Custom Interface The Consultant will develop a custom demand scenario development tool that will be used to estimate water demand under future scenarios. The tool will be integrated into the Utilities modeling system data management system (DMS) with a user-friendly graphical interface (GUI). This tool will implement the demand framework developed in Task 3.3 to generate total demand based on the user-defined preferences. The tool will be designed for flexible applications, allowing generation and cataloging of demand scenarios by selecting multiple potential conditions and threats. Demand scenarios will be available in the database and DMS for the vulnerability analysis to be performed in Task 6. Assumptions for each scenario will be logged in the database as part of the demand scenario cataloging to provide transparency and allow revising assumptions in the future. The Consultant will design the tool consistent with the outcomes of Tasks 3.2 and 3.3 with the main purpose of generating demand scenarios for the modeling system. At a minimum the Water Demand Tool GUI will include:  A map interface showing a spatial view of the selected region for analysis  Spatial coverage (i.e., GMA, Utilities boundaries, city extent)  Demand driver options, assumption toggles, and application criteria  Visualization of demand framework output (e.g., spatial, graphical and tabular) DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381 The Consultant will prepare TM #3 – Future Water Demand Estimating Methods to summarize 1) the information to be considered in the demand analysis; 2) the assumptions and drivers to be used in the demand analysis; and 3) documentation on how to use the demand estimating tool. It is recognized that the ultimate method of estimating future demands for the Vulnerability Study may differ from the process described in Tasks 3.1 through 3.4 based on information obtained during the study, other available tools/methods, or direction from Utilities. The Consultant will base its project budget on the methods described herein. If those methods change, the budget may be changed accordingly. Task 3.5 – Demand Forecasts The Water Demand Tool will be used to estimate future water demand under a broad range of future conditions resulting from variability in the key demand-related risks and uncertainties from Task 4. The result will be a range of future demand projections encompassing the variation in key drivers and uncertainties. These demands will then be applied in the vulnerability assessment in Task 6 to determine the impact of demand on water supply system performance when combined with other factors such as climate change and operational considerations. Task 4 – Identify Water Supply and Demand Vulnerabilities Objective: Identify and prioritize risks, uncertainties and threats to the Fort Collins water supply system, and select key metrics and level of service goals with which to assess system performance. Establish a planning horizon for the Vulnerability Study. DELIVERABLES:  Notes from Workshop 4A – Fort Collins Water Supply Risks, Workshop 4B – Northern Water C-BT Water Supply Risks, and Workshop 4C – Integration of Fort Collins and Northern Water’s Water Supply Risks: documentation of the process and risks identified for each component of Fort Collins water supply  TM #4 – Risks and Uncertainties: summary of identified risks and uncertainties from Fort Collins and Northern Water, a summary of likelihood and impact scores, and quantification of risk impacts where possible without the modeling analysis proposed in Task 6  Notes from Workshop 5 – Defining Metrics and Level of Service Goals: documentation of the discussion of potential system performance metrics and level of service goals  TM #5 – Metrics and Level of Service Goals: summary of identified performance metrics and level of service goals Task 4.1 Risk Identification, Prioritization and Quantification Utilities’ water supply faces many future threats, from climate change and demand hardening to aging infrastructure and wildfires. The Consultant will work with Utilities to identify these risks, quantify how they could impact the water supply system, and prioritize them for modeling. These threats could come from a variety of sources, e.g., legal threats such as Colorado River DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381 Compact curtailment, climate threats such as extended droughts, and infrastructure risks such as emergency maintenance outages. The Consultant will organize the risk identification process around the following categories: climate and hydrology, watershed, operations, legal & administrative, and demand. Workshop #4A &4B – The Consultant will conduct two full-day risk identification workshops. One workshop will be held with Utilities staff and another separate workshop will be held with Northern Water staff. Attendees at these workshops will include broad representation from each organization and include planning and engineering staff, operational staff, financial staff, and leadership. The goal of these workshops is to brainstorm the many potential risks that could occur and classify them based on likelihood and impact using a standardized scoring process. Using a standardized scoring process will allow different risks to be evaluated using a consistent comparative framework (e.g., extreme, moderate, or insignificant threat). During these workshops, the Consultant will leverage subject matter experts within and outside the project team for assessing risks and identifying management strategies. Workshop #4C – Since Utilities water supply system receives C-BT water from Northern Water, coordination between the two agencies during this task will be required. Therefore, the Consultant will conduct a third full-day workshop with water supply staff from Utilities and Northern Water to coordinate and integrate the selection of key risks and uncertainties. Demand-related risks and uncertainties identified in this task will be used to supplement the demand drivers and forecasting uncertainties developed in Task 3.2. Concurrently with the risk prioritization process, the Consultant will estimate the anticipated impacts of the risks on Utilities’ or Northern Water’s water supply system or demands if appropriate. For some risks, it is possible for staff to assign an anticipated impact (e.g., reduction in yield from a watershed, reduction in capacity of a pipeline). Doing this will simplify the vulnerability study while not diminishing the results and allowing modeling efforts to be focused on risks that do not have a reasonably known impact (e.g., climate change, future water use changes). The Consultant will work with Fort Collins and Northern Water to select an appropriate planning horizon for the Vulnerability Study. This is needed to guide the timeframe over which risks and uncertainties will be considered, and will also specify bounds for future demand estimates and climate change effects. The Consultant will prepare TM #4 – Risks and Uncertainties to summarize identified risks and uncertainties from Fort Collins and Northern Water, likelihood and impact scores, and quantification of risk impacts where possible. Task 4.2 Identify Performance Metrics and Level of Service Goals The Consultant will work with Utilities to identify metrics that could be used to assess water supply performance. The Consultant will also work with Utilities to associate level of service goals (i.e., targets or thresholds) with key performance metrics that will enable Utilities to use results from the Vulnerability Study to determine future conditions that force performance of the water supply system into unsatisfactory conditions. These performance metrics and level of service goals will be developed during Workshop #5, a half-day workshop, but could be refined and expanded as new insights are gained during the study. DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381 The result will be a unique set of metrics and level of service goals for Utilities that will allow existing and future water supply system performance to be tested against objective criteria that are useful to decision-makers and can be explained to the public. The Consultant will prepare TM #5 – Metrics and Level of Service Goals including a summary of identified performance metrics and level of service goals. Task 5 – Develop Potential Yield Changes Objective: Develop a set of future hydrologic time series for local system and C-BT inflows based on a range of climate change assumptions using the process developed in Task 2. DELIVERABLES:  Notes from Workshop #6 – Preliminary Hydrology Results: presentation of preliminary application of the hydrologic analysis methods developed in Task 2  TM #6 – Future Hydrologic Analysis: summary of methods and results for computing hydrologic ensembles representing future climate conditions  Updated Modeling Database: updated modeling system DMS incorporating hydrology- derived datasets for the future conditions to be considered in the vulnerability analysis Task 5.1 – Development of Future Hydrology Scenarios for the Modeling System The outcome of Task 2 will be an approved approach for the Vulnerability Study hydrologic analysis. In this task the Consultant will apply the approved approach to estimate hydrologic inputs to the Fort Collins System Model and PBN for a range of future climate conditions or GCMs. Northern Water has a model for estimating C-BT quotas based on Upper Colorado River hydrology. The Consultant will provide the hydrologic changes resulting from application of the methods selected select in Task 2 to Northern Water and will coordinate with them to generate climate change-altered C-BT quotas tied to future hydrologic conditions. Northern Water will actually perform the C-BT quota analysis. Past studies of the correlation between Poudre Basin and Upper Colorado River Basin hydrology will be used to generate compatible combinations of local system hydrology and C-BT yields for use in the Fort Collins System Model. The result of this subtask will be ensembles of hydrologic time series that represent the range of future climate conditions selected for the study as a result of the climate research in Task 2 and the risk identification process in Task 3. Preliminary results will be presented in Workshop #6, a half-day meeting for review and discussion of application of method and initial findings with Utilities and Northern Water. For purposes of the Work Order budget, the Consultant will assume future hydrology will be determined using the following bottom-up approach.  The JFRCCVS calibrated hydrologic models will be used to predict the flow at selected points in the Poudre River basin and in the Colorado River basin. DocuSign Envelope ID: 71DF6A46-74C5-4125-B8FC-89629CE69381  The existing hydrologic model will be used to simulate the effect of precipitation and temperature changes on streamflow.  Results in the Colorado River Basin will be compared to results of the CRWAS and adjusted if necessary to be consistent with the modeling in that study.  The change in flows at the JFRCCVS analysis point will be used to prorate the PBN input based on an average area precipitation weighting to preserve the basin characteristics captured in the historical flows. Based on the refined approach developed in Task 2 to represent future hydrology scenarios and develop the data for the hydrology scenarios, the Consultant may adjust the above approach and associated budget if needed. The Consultant will prepare TM #6 – Future Hydrologic Analysis to document methods and results for computing hydrologic ensembles representing future climate conditions. Task 5.2 – Incorporation of Hydrologic Time Series Into DMS The Consultant will incorporate the climate change-altered streamflow time series predictions for the PBN model into the Fort Collins Modeling System database. The Consultant will develop DMS procedures (e.g., SQL statements and .NET functions) to automate the time series processing for the PBN model’ input nodes, including executing the model and extracting and processing the results to make them available in the modeling system. The PBN model will provide the information to simulate water rights yields for the Fort Collins system, while the C-BT model will estimate the quota for the C-BT users. The Consultant will use the existing PBN import tool in the DMS to process and import the PBN model results and catalog them into the database hydrology sets, including the associated estimated C-BT quotas from Northern Water’s model.
