RPA-HDR Kalispell W-WW PlanDecember 92024Proposal Water and Sanitary Sewer Facility Plan Update City of Kalispell December 9, 2024 Keith Haskins, PEDeputy Director of Public Works/City Engineer201 First Avenue EastKalispell, Montana 59901 RE: Water and Sanitary Sewer Facility Plan Update Proposal Dear Keith and Selection Committee Members: The City of Kalispell is at an interesting point in time with respect to the future of its water and wastewater utilities. Continued growth places increased demands on aging systems, regulatory and permitting uncertainties make your facility planning process complex, and higher costs make completing infrastructure projects challenging. RPA and HDR have partnered with communities throughout Montana to address similar water and wastewater planning issues. Our proposed approach addresses the relationship between planned growth, anticipated regulations/permit limits, infrastructure needs, and the internal and external demands for the City’s resources. For your water and wastewater facility plan updates, we offer: • A Strategic Approach to Meet an Accelerated Schedule: The City needs these facility plan updates completed and ready for City Council adoption by August 15, 2025. To achieve that goal, our team will build upon the City’s existing information and spend our time working efficiently by focusing only on the pertinent components of your water and wastewater systems. RPA and HDR have teamed to ‘divide and conquer’ this work so the schedule can be met, despite challenges that may be encountered along the way. We have found that one of most effective ways to keep a planning project on schedule is utilizing a workshop approach to project execution. A workshop-based approach enables use of resources efficiently and allows the City to give feedback regularly during the plan development. • Unique Expertise and Forward Thinking: Our team includes some of the most knowledgeable individuals in the public works industry. Accurate and workable models of your systems are fundamental to any successful facility planning efforts, so we’ve included experts on our team that are familiar with all available modeling programs in the marketplace. Exposure to this expertise will benefit the City by tapping into long-term thinking. Where use of new software programs may be beneficial, we will assist the City by providing you with the information required to make the appropriate software selection. Additionally, we have engaged regulatory and permitting experts to develop science-based strategies for permit compliance, which allows the City to grow and meet regulations without implementing costly wastewater treatment plant improvements. • Familiarity and Commitment to the City: RPA’s and HDR’s in-depth knowledge of your water distribution, sewer collection, and wastewater treatment systems enables us to move forward quickly with the facility planning process without spending valuable time and money familiarizing ourselves with your facilities and processes. We know you want system improvements to be cost-effective and adaptable with identifiable trigger points to build just ahead of facility needs. At the conclusion of this project, the City will receive clear and concise plans that will be living tools, backed by technically sound science, that can be expanded and adjusted over time as the City grows and your needs change. Finally, as we have done on past projects, we are committed to providing the services required here on budget and within schedule. Please let us know if you would like to discuss anything contained in the following pages of our Statement of Qualifications. We look forward to partnering with you on this critical project.

RELEVANT COMPANY EXPERIENCE City of East Helena | Water Master Plan RPA prepared a Water Master Plan for the City of East Helena in 2018. The 2018 Water Master Plan was used to secure funding for several water system improvements identified during that planning effort. The preparation of the 2018 Water Master Plan, led to several improvement projects being undertaken. An additional groundwater well (Wylie Well #4) was completed to provide an increase in source capacity, the two existing McClellan Creek Radial Well water sources were retrofitted with new pumping equipment and buildings to provide robust and reliable pumping capabilities at the existing water source, a new 1 million gallon (MG) at-grade prestressed concrete tank was constructed to increase storage, and a new 16-inch diameter transmission main is under construction which will provide better hydraulic connectivity to the new 1 MG tank. This is in addition to several distribution improvements projects being completed throughout the existing distribution system. Since the preparation of the 2018 Water Master Plan, the City of East Helena and its surrounding areas have experienced unprecedented growth. Due to this growth coupled with large quantities of undeveloped land previously owned by the Montana Environmental Trust Group (METG) formerly ASARCO being sold to developers with expeditious plans for development, an update of the 2018 Water Master Plan was required. This 2024 Water Master Plan Update focused on identifying the needs of the City’s water system as they correlate to the newest City Growth Model. The 2024 Water Master Plan Update was prepared as a supplementary document to the 2018 Water Master Plan document and focused on water demands, water rights, water sources, water storage, transmission main improvements, and the addition of a new pressure zone within the water distribution system that currently only has one pressure zone. In addition to the water system planning, RPA has also completed a Masterplan for the wastewater collection system and is in the process of preparing a wastewater treatment facility plan that will address the impacts of the development on the existing treatment plant processes. Fee: $90,000 Proposed Completion Date: March 2024 | Actual Completion Date: February 2024 Key Project Staff Members: Brad Koenig, Project Manager; Austin Wargo, Water System Modeler City of Lewistown | Water Master Plan The City of Lewistown’s distribution system is a network of mains ranging in size from 2-inch to 24-inch. Some of the mains were installed in the early 1900’s and were creating issues within the distribution system due to the aging infrastructure. In addition, water samples testing positive for total coliform bacteria were collected throughout the City of Lewistown’s water distribution system. To address the aging water distribution system and water quality violations, RPA prepared a Master Planning document in 2020 which laid out improvements to their water treatment and distribution systems to address the current issues which included assisting the City with entering into an Administrative Order on Consent (AOC) with the Montana Department of Environmental Quality (DEQ) to address the disinfection mandate that was set forth by DEQ. The planning documents created a disinfection timeline with a deadline for a fully operational full-time disinfection system. A project was designed in 2022 and construction was completed in 2024 which addressed many of the issues presented in the Master Plan that RPA prepared. This project included implementation of system-wide disinfection, construction of two new pump stations, modifications to the existing Lower Pump Station, water distribution improvements, and SCADA system upgrades. The City is now fully in compliance with DEQ disinfection standards. Fee: $100,000 Proposed Completion Date: May 2020 | Actual Completion Date: May 2020 Key Project Staff Members: Brad Koenig, Project Manager; Kaela Murphy, Master Plan Author, Water System Modeler, and Project Design Engineer; Neal Levang, Construction Support City of Kalispell | Water and Sanitary Sewer Facility Plan Update "Bozeman faces complex issues related to wastewater treatment and effluent management because we discharge to a small receiving water with an EPA-approved nutrient TMDL and WLA. Compounding these issues are the uncertainties surrounding nutrient water quality standards and effluent limits coupled with maintaining adequate treatment capacity in the face of rapid city growth. To confront these challenges, HDR utilized a unique scenario driven approach for the Bozeman WRF Facility Plan Update, creating "book ends" of a lenient permit scenario and a stringent one, and then a likely scenario in between given our water quality and permit negotiations. This approach was an effective way to understand the range of treatment improvements and costs that Bozeman could face, providing a valuable aid for capital improvement planning." ~ Brian Heaston, City of Bozeman, City Engineer 4 Town of Townsend | Water Preliminary Engineering Report/Master Plan and Water System ImprovementsRPA prepared a comprehensive planning document for the City’s water system in 2022 to evaluate and assess the current condition of the City’s existing distribution system, water sources, and storage capacity. The City currently receives its water from three groundwater wells located throughout the distribution system. Water is pumped directly into the distribution system satisfying system demands while simultaneously filling the City’s storage tank. Water storage is provided by one 200,000-gallon elevated steel tank constructed in 1958. This report identified that the existing water storage capacity was short of meeting the minimum requirements of DEQ, aging water mains and hydrants installed in the 1960’s needed to be replaced, and the existing well pumps needed to be replaced to maintain the minimum required system working pressure with the largest well pump out of service. In 2024 the Townsend Water System Improvements project was designed and is anticipated for construction beginning in 2025. This project will provide a new 1 MG elevated composite tank and 16- inch transmission main to provide hydraulic connectivity to the existing distribution system. The project also includes replacement of the three existing well pumps and buildings, as well as new backup generators for each of the well facilities. Replacement of nearly 40 water main valves and over 40 fire hydrant assemblies were included in the project to provide up to date infrastructure throughout the community. The project and new storage tank will increase the existing system pressure to accommodate growth that is planned in the peripheral areas of the community. Fee: $95,000 Proposed Completion Date: May 2022 | Actual Completion Date: May 2022 Key Project Staff Members: Brad Koenig, QA/QC Reviewer; Kaela Murphy, Water System Modeler; Neal Levang, Design Support City of Bozeman | WRF Facility Plan Update HDR prepared a wastewater facility plan for the City of Bozeman’s Water Reclamation Facility (WRF) that identified cost-effective means and methods to maintain compliance with Montana’s water quality standards as the City continues to grow. The facility plan covered a 20-year planning horizon, and identified capital improvements, process optimization strategies, pollutant minimization program elements, and long-range permit compliance approaches necessary to attain water quality standards as Bozeman’s population increases. Work elements included: flows and loads, monitoring, sampling, and data analysis; discharge permit renewal assistance and long-range nutrient WQS compliance; effluent management alternatives development and analysis; pollutant minimization plan; existing WRF facility major processes evaluations; WRF treatment capacity upgrades alternative development and analysis; solids disposal alternatives development and analysis; and WRF capital improvement plan.

The plan addressed aging infrastructure, growth demands, and increasingly restrictive future regulatory requirements. Additionally, the team updated the collection system with current and future flows to provide a tool for addressing growing development interest in Helena. Alternative evaluations considered changes to the overall lift station configuration, which along with operation and maintenance adjustments, will improve overall system reliability and cost efficiency. Fee: $378,898 Proposed Completion Date: February 2025 | Actual Completion Date: Pending Key Staff Members/Roles: Coralynn Revis, Wastewater Lead City of Billings | WRF Nutrient Recovery and Biosolids Facilities Plan HDR completed a facility plan for the City’s WRF in 2012. The plan included thorough evaluations of the shifting nutrient regulations on the Yellowstone River and identified pathways through which the Billings WRF would be able to remain in compliance with nutrient standards. The plan included biological nutrient removal and plant-wide improvements. HDR provided an updated review of the City’s solids handling practices, nutrient recovery, and biogas recovery analysis, looking specifically at primary clarifier requirements, primary sludge thickening, Calprex/other recent nutrient recovery developments, and potential associated benefits to the biogas composition. The City’s goals are to: recover phosphorus; reduce hydrogen sulfide in the biogas; increase dewaterability of the biosolids; reduce polymer usage for dewatering; provide volatile fatty acids for the biological nutrient removal (BNR) process; increase biogas production; reuse existing infrastructure to the extent possible; and meet goals in the most cost-effective manner. The plan analyzed multiple nutrient recovery options for phosphorus recovery and the associated impacts on the ancillary processes including processes before and after the sludge dewatering. The alternatives included Airprex, Calprex, modified Calprex, Ostara and composting. Ultimately, the implementation of direct dewatering of the WAS for compost was the recommended alternative. The plan will: summarize and update projected residuals in the process; evaluate best use and operation of primary clarifiers; update phosphorus recovery evaluation with a focus on Calprex; analyze other side stream treatment options for nitrogen and/or ammonia removal; determine need for third gravity thickener; update recommendations for primary clarifiers, residuals, side stream treatment, and nutrient recovery and provide recommendations for hydrogen sulfide reduction in the wastewater system; and summarize in a report.

CONTRACT UNDERSTANDING AND APPROACH Understanding of Kalispell’s Need for Professional Services The City is experiencing rapid growth and the Public Works Department needs to complete these updates to accommodate that growth while maintaining the same level of services to its citizens. The planning documents will be used to coordinate with the Development Services Group to meet the requirements of Montana Senate Bill 382. These updates need to “build” on what has been completed in the past while confirming that past recommendations and assumptions are still valid. RPA and HDR have comprehensive and proven experience with the City’s water system, wastewater collection system, and wastewater treatment plant. This knowledge and experience will be valuable when meeting the schedule required to complete the facility plan updates. To streamline the process with the City Council, Development Services, and the public, these documents need to convey information graphically and simply to expedite the transfer and understanding of information. Our team will keep these goals in the forefront of our minds during the 8-month period that these plans are being prepared. The 2002 Water, Sewer, and Storm Drainage Facility Plan, completed by HDR and partner firms, represented a comprehensive planning effort by the City of Kalispell and provided a multi-year framework for utility improvements. The consultant team updated the water distribution, wastewater system, and storm water collection portions of the 2002 plan in 2008 due to a significant increase in population growth. City leadership desired to take a more expansive look at the planning area around Kalispell to determine how far out the City could reasonably serve growth up to the year 2050. The expanded study area and changes in growth projections (to reflect more contemporary growth trends) resulted in a potential service area population approximately three times larger than the area utilized in the 2002 plan. Following the adoption of the 2008 Plan, many improvement projects were completed. However, a recession led to an economic downturn and growth slowed significantly. As a result, the planning and service areas were later revised to match the City’s adopted Annexation Boundary as described in the Kalispell Growth Policy. New demands on infrastructure from development and growth warranted further updates to the City’s facility plans. The City subsequently completed the Water Facility Plan Update in 2018 and the Wastewater Facility Plan Update and Advanced Wastewater Treatment Plant Facility Plan Update in 2019 to provide continued service to the citizens of Kalispell. The City has now completed another round of capital improvement projects previously identified in the current facility planning documents. However, aging infrastructure, continued development, and increased project costs once again necessitate revisiting a plan for future growth. Recent regulations related to lead, copper, per- and polyfluoroalkyl substances (PFAS), and nutrients are factors that must also be considered in the upcoming planning efforts. Of upmost importance for this work, particularly as relates to project schedule, are the requirements presented in Montana Senate Bill 382. The bill requires a new land use plan to be adopted by May 2026. It is therefore imperative that the facility planning work required here for water and wastewater infrastructure be completed by the fall of 2025 to meet the deadline required in Senate Bill 382. 9 City of Kalispell | Water and Sanitary Sewer Facility Plan Update 10 Recommendations for Modeling Software The City currently has an InfoSWMM model and InfoSewer model for their sewer collection system modeling software and InfoWater Pro for their water system modeling software. All software platforms were originally developed by Innovyze. Recent developments in the GIS software and hydraulic modeling software spaces will have impacts on the software that the City uses moving forward. First, ESRI, who developed and supports ArcGIS Desktop (also known as ArcMap) has made a business decision to discontinue the ArcGIS Desktop platform and transition to ArcGIS Pro, which is a 64-bit more collaborative application. This has downstream implications as third-party software that runs within the ArcGIS Desktop environment will eventually become unsupported “legacy” products. Both InfoSWMM and InfoWater run in the ArcGIS Desktop environment. Secondly, as relates to the hydraulic modeling software space, Autodesk recently acquired Innovyze (the original developers of InfoWater and InfoSWMM). Through various Innovyze acquisitions over the years, Innovyze ended up with four separate sewer modeling software platforms; InfoSWMM, InfoSewer, InfoWorks ICM, and XPSWMM. With the discontinuation of ArcGIS Desktop, Autodesk has decided to streamline their sewer modeling software and InfoSWMM and InfoSewer will not be compatible with ArcGIS Pro.

We have supported many clients through this selection process and our extensive experience with all of these programs benefited our other clients, based on their individual needs. It should be noted that Innovyze has already converted InfoWater to ArcGIS Pro, so there is an ArcGIS Pro version called InfoWater Pro, which has been available for about five years. There is also a relatively new company in the modeling space, Aquanuity, founded by Paul Boulos (former Innovyze CEO), which was developed in and runs native in ArcGIS Pro. Aquanuity has significant performance benefits. The modeling software experts on our team have extensive experience in all of the commercially available software platforms and will prepare an evaluation specific to the needs of the City. Examples of water and sewer software evaluations are provided in the tables below. After considering the available options, the City may elect to maintain utilization of the existing InfoWater Pro program for the water modeling effort. This program allows GIS information to be updated and has a wide array of self-explanatory graphical outputs. Another benefit is that RPA has already been using the City’s existing model extensively and their team has some thoughts on how to improve the model while not re-creating the wheel. Please note that RPA is willing to model the system in whatever program the City ultimately prefers. Major modeling efforts will be completed after a consensus on the future planning area boundary for the water distribution and wastewater collection system boundaries. Planning uses and densities would need to be established to develop seasonal water demands and duty factors. Our team proposes to establish short-term, mid-term, and long-term models to help establish priorities and better define future capital outlay. These models need to incorporate control strategies and operations within each pressure zone. The most streamlined approach would be to provide these models as a “draft” before May 1st of 2025 and review problems, potential needs, and solutions. A final version would then be completed by June 1st for incorporation into the final document and used to develop graphical representations. All model files would be provided to the City electronically. City of Kalispell | Water and Sanitary Sewer Facility Plan Update 11 ISSUES AND DESCRIPTION MITIGATION APPROACH Schedule: The City has clearly expressed the need to have the facility planning documents completed and ready for City Council adoption by August 15, 2025 in order to meet deadlines required by Senate Bill 382. Combining the water distribution, wastewater collection, and wastewater treatment facility planning into one project results in the need to complete a significant amount of work in a relatively short timeframe, especially considering unknowns associated with modeling data, future regulations and permitting limitations, or even the need for public outreach/input associated with the basis of planning phase of this project. Given the importance of schedule, RPA and HDR have teamed to ‘divide and conquer’ work activities so schedule issues can be addressed, despite challenges, known or unknown, that may be encountered. Details related to our team approach are included in the next section. Modeling Software: Sunsetting Modeling Software Could Negatively Impact Project Execution/Schedule The selection of new modeling can have a significant impact on the project, and especially project schedule. One approach would be to model the facilities with existing software and then at the end of the project choose the new software and make the conversion at that time. This might initially appear to be a preferred option given the time it might take to choose the modeling software, get the new software operational, and deal with the learning curve involved with the new software. However, the significant downside of this approach is the fact that model conversion at the end of the project requires revalidation of the model prior to its use, thereby extending the project schedule through redundant work. Our modeling team has extensive experience with all of the water modeling software mentioned previously and have helped many clients with this process. Our thorough knowledge of the advantages and disadvantages of each program will help Kalispell decide early in the process and we already have access to these models so we can quickly make the conversion as well as completing the model validation and calibration. Land Development: The facility planning process will be occurring at the same time the 2025 Montana Legislature is in session. A possible challenge is that proposed legislation and/or rulemaking could have a significant impact on the facility planning process. Of particular concern will be the issues surrounding the current ‘exempt well’ rulemaking and the impact on land development just outside the City’s boundaries due to water supply and water quality issues. The establishment of proposed ‘red’ and ‘yellow’ zones (based on groundwater and surface water quality) may result in increased pressure to further extend water and sewer service areas beyond current boundaries. Our team, and particularly Dave Clark, is actively working with the Montana League of Cities and Towns as it relates to this issue, including helping with the rulemaking process. Addressing these issues could have a significant positive impact on the City of Kalispell, especially with upstream water quality and future effluent permitting. Given our connection to these issues, the RPA/HDR team will be able to advise the City of Kalispell in real time how draft rulemaking could affect the current planning process. This unique knowledge will allow the team to shift quickly as future rules and laws make their way through the legislative process so the final facility plans are based on the most current regulations. ISSUES AND DESCRIPTION MITIGATION APPROACH Regulations (Drinking Water): There are project and planning impacts of regulations associated with the recent Lead and Copper Rule, PFAS, etc. The City as completed the necessary inventory for lead service lines as required by EPA regulations under the lead and copper rule. A plan for replacement is required to be completed by 2027 and will need to include funding mechanisms for the costs associated with the required replacements. Implementation of the plan currently must be in place by 2037 however changes in ongoing regulations could alter the current action plan that the City has developed. PFAS regulations implemented by EPA in 2024 had a significant impact on the City’s water system with detections in several existing water sources. RPA is assisting the City with a preliminary engineering report to address the PFAS detections and explore alternate water sources. Future regulations, changes to the existing regulations, or additional detections within the system would change the current action plan that has been put in place to address the detections found to date and comply with the latest EPA regulations on PFAS. Information and Data Gaps: Are there data gaps that impact distribution, collection and treatment modeling? How do we address this without affecting schedule? The City’s existing GIS database will be a great asset during preparation of the masterplan updates; however, missing pieces of information may be encountered. RPA has local staff and surveyors that are familiar with the City of Kalispell’s existing infrastructure which can help garner missing information to mitigate schedule or budget impacts. Regulations (Wastewater): Ongoing Regulations can have an impact on WWTP Permitting, Future Effluent Limits, Ashley Creek Use Attainability Analysis, PFAS in Biosolids, etc. It can be challenging to create a Capital Improvements Plan when future regulations, standards, and permitting are unknown. Furthermore, when future permitting might be dependent on the outcome of the Ashley Creek UAA, regulatory agency decisions, etc. a clear pathway forward may not be apparent. Dave Clark’s knowledge of permitting and his influence with and relationships within MDEQ and EPA provide a unique insight into what a future regulatory environment might look like and, more importantly, how to counter the future effluent limits with science and water quality information. HDR recently addressed this very issue for both Bozeman and Helena by creating "book ends" approach consisting of a lenient permit scenario and a stringent one. We then developed a likely scenario in between given our water quality expertise and knowledge from permitting negotiations. We then went through a stepwise process where certain triggers are activated resulting in the needed improvements, not stranding any assets, for what would be needed if various permits were triggered. Finally, the use of HDR developed tools, including WaterSPACES, allows for the efficient modeling of various improvements scenarios based on the range of potential effluent limits. Final Document: Facility Plans Contain Complex Information that Needs to be Easily Communicated to Council, Public, Developers, etc. We believe that our industry has reached the end of the days where the final deliverable of a facility planning project is a 4-inch binder that sits on the shelf and collects dust. Further, this type of deliverable is static and cannot be easily amended as things such as growth and regulations change. While delivering a paper copy of the facility plans is still our intent, it will be important to provide an easily digestible infographic for public and even City Council use. This has been included in our work plan as described in the next section. Our team will work closely with you to put all Facility Plan Update information at your fingertips, in a tailored electronic dashboard (if desired). Additional information is included in our scope below. We recognize how busy both City staff and our consulting team are and feel that scheduled meetings between our Team and City staff would be beneficial to making sure that there are not any outstanding project issues and to keep communication flowing. We suggest bi-weekly (Microsoft Teams and/or in-person) meetings to provide an end product that is precisely what the City anticipates. Potential Issues and Mitigation Approach As with most projects, there will likely be issues that arise for our team to address. Although the challenges encountered may be difficult, we have the right group of professionals to identify the issues early and effectively work through them. Our team has a proven approach based on a vast amount of experience and has the qualifications necessary to complete the project. The following table identifies and discusses some of the potential issues that this project might encounter and how our team will mitigate those potential issues. Diminishing aquifer levels and water quality in the Flathead Valley as a result of exempt wells and onsite wastewater treatment systems has a direct impact on Kalispell’s water supply and effluent permitting, and as a result may impact decisions during the Basis of Planning. 12 City of Kalispell | Water and Sanitary Sewer Facility Plan Update V. APPROACH TO CONTRACT MANAGEMENT I. Present a brief description of how the firm intends to organize and conduct the project The RPA and HDR Team will organize the project so that the City of Kalispell will have one primary point of contact. The secondary points of contact will be Neal Levang with RPA and Rickey Schultz with HDR. Brad and Rickey have worked together to deliver some of Kalispell most successful projects. We have found that one of most effective ways to keep a planning project on schedule is utilizing a workshop approach to project execution. A workshop-based approach enables use of resources efficiently and allows the City to give feedback regularly during the plan development. The advantages of this approach include: • Workshops allow City staff to participate, insert opinions early, and gives our team an opportunity to listen. They also provide an opportunity for participation during plan development before significant writing occurs. • Workshops with interim deliverables will help City staff understand the projects identified and associated costs without having to spend a significant amount of time reading. • Workshops help the team stay on task since deliverables are provided at multiple intervals. Discussions held during the workshops and the resulting decisions are further developed into the overall outline and chapters of the Facility Plan, allowing for City involvement throughout the process. There is flexibility in the workshop format, where the number of workshops can be adjusted or workshops planned to be in-person could be conducted as video conference meetings. Although we will adapt with your input, our initial thoughts on the approach are outlined in the figure on the following page. Our proven workshop-based approach has benefited clients with similar needs. II. Describe your company’s approach in initiating and establishing the service that meet the needs and requirements of the City Our proposed approach to initiating and establishing services that exceed the City’s expectations is founded on our Project Manager leading this team and providing clear, concise and frequent communication. We will conduct a project scoping discussion with City staff to clearly understand the City’s expectations and schedule for the project. Following that discussion, we will establish an agreement and prepare individual tasks. The tasks will detail specific parts of the project, the work anticipated, the expected deliverables, the schedule and the fees. These individual tasks are developed jointly with our team and the City to make sure that only work requested is being completed and that all work is authorized by the City. III. Provide a narrative outlining a proposed scope of work that includes description of each task and work product, and a concise explanation of the firm’s approach to accomplishing the tasks As noted above, the scope of work can be broken down into three distinct, parallel tasks, after the Basis of Planning. After the planning criteria are set, we anticipate three different teams overseen by the Project Manager to execute the Water Distribution, Wastewater Collection, and Wastewater Treatment analysis and facility planning simultaneously. Work under each of these major tasks will be subdivided into subtasks with workshops and delivery of a chapter of the facility plan and intervals shown on the schedule. The following is a brief synopsis of our proposed scope of work which includes deliverables and keys to success to benefit the City of Kalispell. TASK 1: BASIS OF PLANNING The Basis of Planning will establish the planning constraints, clarify the issues that will impact planning decisions, and provide a clear foundation for the development of the alternatives for the City’s drinking water and wastewater facilities. Kick Off Meeting It is anticipated that the major sub-tasks of this first step would be a kick-off meeting which would include a review of potential water and sewer modeling software options, including price, advantages, and disadvantages, so that this issue can be resolved as early as possible in the planning process. The kickoff meeting also can be used to establish the foundation for the basis of planning including the proposed planning area boundary, source of information for population projections, and exchange of information such as recent wastewater flow and water demands. Following the kickoff meeting, our team will work to create the basis of planning which will be presented to the City during the first workshop. Alternatives Workshop Our tried and true method to successfully delivering facility plan work is to utilize a workshop-based approach, which utilizes resources efficiently and allows for regular engagement with and feedback from City staff.

Demands associated with increasing development need to be developed with an element of flexibility. These are growth dependent and can vary considerably over the years depending upon population expansion or the lack of it. Additionally, planning for a non-reasonable future could have significant impact on facility sizing and CIP requirements. Our team’s comprehensive approach to demand and flow projections, successfully applied to various other clients, helps ground-truth long range planning by providing the City with water demand bookends to account for population fluctuations and uncertainty in growth. By proceeding in this manner, these demand and flow projections will provide a sound basis for informed decision making. Consideration of the legislative action to encourage affordable housing and allow “additional dwelling units” or ADU’s on properties inside the facility boundary will need to be taken into account when determining the anticipated flows over the area. An evaluation with the planning department will provide some guidance on the industry trends for the occurrence of ADU’s and estimation of land use planning will allow for the impacts to be taken into account for these facility plans. Basis of Planning Workshop and Chapter DevelopmentThe final sub-task of the Basis of Planning will be the team workshop with RPA/HDR and City staff. As noted above, the workshop will be an opportunity to receive feedback on the work completed to date which will be incorporated into the Water Facility Plan and Wastewater Facility Plan Basis of Design draft chapter. DeliverablesThe deliverables for this Task will be meeting notes from the kickoff meeting, workshop, and the draft and final Basis of Planning Chapter for the water facility plan and for the wastewater facility plan. This task will be led by Brad Koenig and supported by Rickey Schultz and Neal Levang. Benefits to the City of Kalispell• Accurate planning data serves as the foundation for timely, cost-effective solutions. • A design basis for water and wastewater planning depends on a strong understanding of how and where a community will grow, expand its service area, and project future populations. • The basis of planning needs to consider changes that could occur during the upcoming legislative session, including rulemaking around exempt wells and the potential limitations on county development adjacent to larger municipalities like Kalispell where growth outside the City is impacting groundwater availability, groundwater quality, and surface water quality… issues that all have a direct impact on the City of Kalispell. Our relationship with the League of Cities and Towns and involvement in rulemaking gives our team a unique perspective related to this issue. TASKS 2 – 4: WATER AND WASTEWATER FACILITY PLAN UPDATETasks 2, 3 and 4 will include work associated with the update to the Water and Wastewater Facility Plans. We anticipate completing this work in three parallel efforts with the wastewater facility broken into collection and treatment. The following is a discussion about our proposed scope for these tasks and the benefits that RPA and HDR bring to the City of Kalispell and this project. Water and Wastewater CharacterizationThe first sub-task will begin with the characterization of the water quality of the current water supplies and wastewater influent, with an emphasis on per- and polyfluoroalkyl substances (PFAS). Though members of our team have found a sustainable solution for this in the near-term, it will be important to keep an eye on the drinking water quality and the impacts of future regulations. Wastewater characterization will also focus on those constituents that may have the greatest impact plant capacity and effluent limits, including but not limited to BOD, Ammonia, and PFAS. An industry trend around the nation is that while flows are not increasing as steadily as previously, we’ve seen an increase in the concentration of many wastewaters. What this means is that we need to consider the overall loading and impacts to the unit processes, and not just the hydraulic impacts of the flows, when determining if upgrades are warranted. System Evaluation and Risk Assessment The evaluation and risk assessment will build on the risk methodology the City utilized for the previous master planning efforts and we will apply it to the treatment facilities. Our team will work collectively with City staff to assign weighted risk criteria that can be pulled from the City’s asset management program. This will provide a likelihood of failure and quantify the impact to users, businesses, schools and the public health will help the City identify high priority improvements. Water quality and permitting will also be a key element of the system evaluation. Kalispell is in the process of pursuing a Use Attainability Analysis (UAA) to alter the required permit endpoints that are currently listed in the TMDL. The lack of defined permits at this juncture can be mitigated by determining alternative permitting scenarios and then laying out a strategy that can be modified to whatever the permitting outcome is. In the case of Kalispell, we might pick 3 mg/L TN and 0.03 mg/L TP as a “worst case” scenario and then maintaining the 15 City of Kalispell | Water and Sanitary Sewer Facility Plan Update existing performance over the growth period, as our least stringent option – this might be 8 mg/L TN and 0.10 mg/L TP. The challenge will be maintaining this discharge permit over time, because the permits are typically in loads. As flows increase, it can be more difficult to meet those requirements. An interim permit scenario could be something around 6 mg/L TN and 0.3 mg/L TP. In order to meet this value, it’s possible that configuration of the treatment train to create a step feed, or post-anoxic zone, could meet the requirements with minimal improvements. HDR’s knowledge of your system will allow these alternatives to be evaluated cost-effectively. Linking facility planning with permitting negotiations results in a discharge strategy that allows continued growth. Our work on the Ashley Creek Use Attainability Analysis (UAA) gives our team unique insights as to the effect of future potential regulations on the treatment plant unit processes. The City has invested in developing an understanding of the nuances of Ashley Creek and as a result our team has a better understanding of the science of the creek and can more accurately speak to the actual health of the creek than MDEQ. An effective permitting strategy provides for continued growth without being limited by discharge requirements. Employing cost- effective, basin-wide strategies for permit compliance allows the City to grow and meet permit requirements without costly treatment improvements. As an official Cityworks implementation and integration partner, we have a vast amount of experience implementing this software for clients throughout the country and we have developed value-added, proprietary tools that allows HDR to push and pull data in and out of Cityworks. As such, we are well versed in how Cityworks is constructed, what its capabilities are and how to access data. From a distribution and collection system performance, we are well equipped to review their risk analysis. We have experience building risk models using system condition data, system performance data as well as environmental information that could be factors in the failure and/or failure impacts to the surrounding community. It is important to note, however, that one downside of a risk analysis built in Cityworks, is that it only has the capability of building risk factors from data housed within the Cityworks database. Using Cityworks, our team has also assessed risk at wastewater treatment plants using multiple methods and at different levels in the hierarchy. We recommend the approach of working down from the top to assign the importance of unit process/location scoring for consequence of failure. Then, a layer of importance can be added for systems or even down to assets (for critical assets). Our experience has been that getting down to the unit process level should be adequate for facility planning purposes. Projects are usually bundled by process area/unit process. Model UpdatesThe second step will be the modeling efforts associated with each system; distribution, collection and treatment. Should the City of Kalispell choose to change the water or collection modeling software, it is recommended that the change occur at this part of the planning process for the reasons noted above. RPA and HDR will utilize the City’s water and collection system models and incorporate updates to the existing system including infrastructure changes, operational changes, and water demand/wastewater flow changes provided by the City which have taken place since the development of the City’s model. The models will be calibrated/validated based on City-supplied data. The system will be analyzed under various existing and future demand conditions to identify hydraulic deficiencies and improvements required to meet demands. The water system analysis will evaluate the need for storage requirements and potential locations for future storage infrastructure. The collection system analysis will include an evaluation of existing lift stations, and potential elimination of lift stations in areas where regionalization makes sense. A future near-term scenario will be developed including near term known or likely to occur developments, and a 20-year growth scenario will be developed that includes future demands spatially allocated based on development projections. These future scenarios will include adjustments to the existing conditions scenarios as necessary such as densification, land use changes, accessory dwelling units, water conservation, and changes to per capita demand. Average day, maximum day, and peak hour scenarios will be developed within the model based on per capita demand and projected future development. Water modeling updates and subsequent capital improvement planning should better incorporate the City’s control strategies when evaluating risks to better mimic “real-world” results and predict operating issues. Storage, new water sources, and piping improvements should be carefully evaluated to alleviate the pressure dips currently experienced in the hospital area, but not create unnecessarily complicated control strategies. Storage locations should be strategically located to operate in concert with the existing infrastructure to improve operations and maximize the return on capital improvements. RPA is currently working with the City to locate water sources in strategic locations based on modeling results to improve water delivery and try to minimize the pressure dips experience in the hospital area. RPA has been utilizing the City’s existing model extensively through design of the new 1 MG elevated storage tank and to assess locations for the Grandview and Armory Wells where PFAS has been detected. We feel future modeling efforts should better delineate the operating conditions between the upper and 16 City of Kalispell | Water and Sanitary Sewer Facility Plan Update lower pressure zones. This would include the demands and control strategies utilized. Utilizing the City’s actual approach to control will be advantageous in identifying needs and mimic actual conditions to provide predictable results. The City’s Biowin model will also be updated to include the current influent characteristics, growth projections, and bookend scenarios for future effluent limits. As an element of the project, a modeling manual and a facilitated model training program can also be provided to City staff. Alternative Analysis and CIP Development The analysis of potential improvements alternatives provides the City with the basis for future implementation and adaptation. The process will begin with a workshop where, as a group, an initial list of alternatives will be created along with the scoring criteria. Once created, the alternatives will be developed in detail along with project cost estimates and ultimately scored based on the established criteria. Then, based on the results of the risk assessment, the alternatives will be prioritized and rolled into a draft capital improvements plan. The more complicated aspects of this task are the unknowns associated with future effluent permitting and the impact at the wastewater treatment plant. HDR’s investment in the development of plant site planning technology provides strong benefits to your planning process. Our proprietary WaterSPACES tools provide real-time treatment plant site planning, component sizing, layout, and parametric cost estimating for projects in the predesign, design, or in progress. Treatment specialists across HDR have assembled a unit process library that can be fully customized by each design team. For example, WaterSPACES can be used to test layout arrangements; find optimal tankage number, size and configurations; calculate chemical and power consumption, and energy demand; and generally manipulate appropriate variables in plant planning to optimize cost and performance. The cost model can also calculate the capital, construction, and operations and maintenance costs of treatment unit processes. This unique tool enables iterative planning and best-value decision making while improving client confidence in the cost estimation of their decisions, while there’s still time and money to change course. These tools can assist with analyzing the alternatives, but the playbook for decisions will be a complex process. Permitting outcomes and effluent management will set the boundary condition for the needed effluent end points. The plant process and technologies will be scored and ranked against each other to form solutions sets. The solution sets are narrowed during the alternatives analysis and then scored against the growth and flow projections to determine the preferred alternatives and timing. All of this is then used in the Capital Improvements Plan. Once the implementation plan for the preferred alternative(s) has been validated through the cash flow and funding analysis, a specific Capital Improvements Plan will be prepared to identify triggers, recommended projects, anticipated timing, and associated costs. The format can be a living document that has set triggers and growth rates that indicate when the improvements are required and adjust accordingly. While a rate study includes the financial impacts of the planned capital projects as a snapshot in time, the EconH2O tool allows for live planning and adjustments, while varying pairwise options to give a complete overview. This will help the City make good decisions, particularly in a changing permit climate. Workshop and Chapter Development At every major milestone, our team will host a workshop HDR’s WaterSPACES tool allows for real-time treatment plant planning as improvement alternatives are considered for various growth and/or permitting scenarios. The WaterSPACES tool was used during the Bozeman Wastewater Facility Planning process to quicky assess the impact of a broad range of permitting scenarios. 17 City of Kalispell | Water and Sanitary Sewer Facility Plan Update with City staff to review the data, assumptions, alternatives and recommendations developed through the planning process. As noted previously have found that early workshops are an extremely efficient approach to exchange system knowledge and promote discussion on key areas such as: forecasting spatial water demands, development of design criteria and system/zone seasonal/daily diurnals, alignment of GIS and model synchronization tools/approaches, and model calibration for system simulations. In total we anticipate the following workshops and scheduled dates. Note that the City can choose to have the water distribution, wastewater collection, and wastewater treatment workshops all in one day or spread out over three different days. It is anticipated that this will be determined at the Kickoff Meeting. • Basis of Planning • Water Distribution, Wastewater Collection, and Wastewater Treatment Analysis • Water Distribution, Wastewater Collection, and Wastewater Treatment Alternatives and CIP Two facility plans will be developed, one for water and one for wastewater. It is anticipated that the various key report chapters delivered as milestones will be as follows: Water System Basis of Planning Water System Analysis Water Capital Improvements Plan Wastewater System Basis of Planning Wastewater System Analysis Wastewater Capital Improvements Plan DeliverablesThe deliverables for this Task will be meeting notes from the various workshops, and the draft and final chapters developed during this phase of the project. This water system facility plan related tasks will be led by Brad Koenig, RPA and HDR will collaborate on the wastewater collection portion of the wastewater facility plan, and the treatment portions of the wastewater facility plan will be led by Cora Revis and Rickey Schultz, respectively. Support for our team leaders will come from our experienced staff as shown in the organizational chart. Benefits to the City of Kalispell • As a result of RPA and HDR’s involvement in the current management of the City’s water and Biowin models, many of the required changes and updates have already occurred resulting in a streamlined modeling process. • RPA’s background with water system PFAS management provides clear insight related to future water quality management. • HDR’s Biowin Model includes our unique proprietary add-ins that were designed by HDR staff to enhance dynamic state analysis resulting in more accurate process model results. • HDR’s knowledge of your facility will allow a quick analysis of each unit process for the newly-created flow and growth projections. Having designed much of the facility back to 2005, we can streamline the process capacity evaluation. • HDR’s WaterSPACES tool can be used in a live workshop for immediate cost estimating and site planning, leading to an efficient and cost-effective process. • HDR’s EconH2O tool allows for effective CIP planning of planned improvements and can be easily modified over time, leading to more effective long-term planning and timing of projects for the City’s budgets. WATER AND WASTEWATER FACILITY PLAN DELIVERY Based on our team’s experience working around the United States, the days of delivering only a traditional paper copy of the final facility plan are nearing an end. Development of a Living Facility Plan We propose a living Master Plan that will be more beneficial and accessible than a Master Plan that is finalized and then placed on a shelf. The living Master Plan is developed in a collaborative effort with work products and contents of the plan residing in a shared workspace as electronic documents (such as Storymapping, Unifier, Sharepoint, ProjectWise, etc). As projects are implemented and new information is developed, it can be incorporated into the Facility Plan so that it remains a relevant and current guide for the overall program. While delivering a paper copy of the facility plans is still our intent, it will be important to provide an easily digestible infographic for public and even City Council use. If requested our team will work closely with you to put all Facility Plan Update information at your fingertips, in a tailored electronic dashboard (if desired). BI Dashboard has been widely lauded by our clients as the most helpful tool in pivoting from an integrated plan to implementable action. Fully customizable, we would discuss pulling together individual dashboard pages that let you view and interact with: water demand, wastewater flows, and water supply trends in real time; and the full list of projects, cost tracking, funding status, and rate projections to support capital investments. Portions of the dashboard could be surfaced for public viewing via a website or other community outreach tool. Examples of these tools are shown below. 18 City of Kalispell | Water and Sanitary Sewer Facility Plan Update IV. Describe a proposed time schedule of work with key milestones and product deliveries Presented in the figure below is our proposed schedule illustrating how we will strategically utilize three qualified teams working concurrently to achieve milestones and submit deliverables on time. The RPA/HDR team will work collectively to conduct a project kickoff meeting during which we will discuss options, pros, and cons for various modeling software packages. Our team will then establish the basis of planning information with the City and divide into the Water Planning Team (led by Neal Levang), the Wastewater Collection Planning Team (led by Coralynn Revis), and the Wastewater Treatment Plant Planning Team (led by Rickey Schultz). All teams will have direct and regular access to our Project Manager, Brad Koenig. Brad provides a common linkage for each team and he will make sure all team members have the resources they need to achieve the milestones set out in our schedule. HDR’s EconH2O tool helps create a ‘living’ facility plan by allowing for easy modifications to the capital improvements and implementation plans to address growth milestones and permitting requirements.
