SURVEYING 2PROJECT OVERVIEW AND APPROACH AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 2.1 WESTWEST MIDDLEMIDDLE EASTEAST 2 PROJECT OVERVIEW AND APPROACH PROJECT OVERVIEW Rapid community growth and an evolving regulations have driven a need to expand the City of Bozeman’s Stormwater Division services. The 2008 Stormwater Facility Plan provided an initial path, but with recent regulatory changes, ongoing development, and stormwater funding challenges, the City needs an updated vision and new tools to continue to meet its two key objectives of: A) maintaining and rehabilitating existing infrastructure, and B) efficiently planning for and adapting to growth.

Objective A: Maintain and Rehabilitate Existing Infrastructure CHALLENGE: A1: Storm sewer installed prior to 1980 in need of rehabilitation or replacement. A2: Poorly maintained private stormwater facilities. A3: Lack of maintenance plans for historic irrigation ditches used for conveyance. 2PROJECT OVERVIEW AND APPROACH AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 2.2 PROJECT APPROACH Proposed Scope Based on our understanding of the City’s objectives and the key challenges to meet those objectives, we have developed a tailored project approach for each of the tasks requested in the RFP so that you have a comprehensive and lasting Facility Plan. Our Project Management Approach is described in detail at the end of this section. AE2S has a proven track-record with the City of delivering successful projects, transparently communicating with you, and diligently collaborating with our teaming partners. We look forward to offering you the same level of service for your Stormwater planning needs. Norton Ranch Stormwater Basin Task 1 Deliverables: • Meeting Minutes • Correspondence • Regular Updates on Progress, Budget, and Schedule • QA/QC Deliverable Task 2 Deliverable: Technical memorandum summarizing recommendations in a format(s) that clearly communicates to the various stakeholder groups (City staff, elected officials, developers, HOAs, and other private BMP owners). Since private post-construction stormwater BMPs connect to your system, maintaining them is critical to meeting your utility’s mission both for MS4 water quality compliance and reducing flooding complaints. The ability to effectively inspect and maintain these private BMPs has become a major headache because the City often lacks access to inspect facilities and lacks a formal enforcement policy. We recognize that to address these issues, you want to better understand success stories and lessons learned from other communities throughout Montana, as well as other communities with similar challenges. We propose the following approach: • Leverage our team’s first-hand knowledge working with the Montana MS4 advisory group in developing the State’s new permit requirements. • Leverage our team’s first-hand knowledge working with a broad range (geographically and demographically) of communities as they implement and manage their stormwater system. Communities with older MS4 programs struggled with many of the same challenges that you are struggling with today. By selecting the AE2S Team, we can hit the ground running with these first-hand success stories and lessons learned. • Leverage our team’s (TD&H) history of working with City staff on development reviews. Task 1 - Project Management Task 2 – Post-Construction Facility Recommendations 2PROJECT OVERVIEW AND APPROACH AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 2.3 Pre-1980s System Approach Applicable Geographic Areas: Primarily East Area (see map on page 2.1) Approach Justification: Based on the RFP, the City is concerned not only with overall pipe capacity but also nuisance flooding, which can be driven by insufficient inlet capacity. To address both potential inlet and pipe capacity issues, we will use a proven approach to quickly model the system and get the City accurate results and able to efficiently determine the best overall approach to improve long-term resiliency. 1 BigGulchDrSpringhillRd Tr oo p e rTrlHar p erPuckettRd Bridger Dr S 3rd RdHitchingPostRdSChurchAveBlackwood Rd S 11th AveManley RdW Babcock St McIlh attan R dDavis LnN19thAveStoryMillRdW College St Goldenstein Ln Highland BlvdW Main St OakSt W Oak St StateHwy86Frontage Rd US Hwy 10 Patterson Rd Stucky Rd Baxter Ln SourdoughRdDurston RdW Durston Rd S 19th RdFowler LnI- 90 Huffine Ln State Hwy 84US Hwy 191 Cottonwood Rd2 1 3 Building on AE2S’ extensive InfoSWMM and regional stormwater treatment planning experience, we recommend the existing storm sewer capacity analysis (Task 3) and the regional stormwater treatment planning (Task 4) be combined into a single model using InfoSWMM’s powerful Scenario Manager harnessed by AE2S InfoSWMM experts. Recognizing that a detailed InfoSWMM model that covers the City’s entire Growth Boundary would likely not provide value for the dollar, we recommend that the level of detail be scaled to the City’s planning horizons: an approach successfully implemented for numerous AE2S municipal clients, including Kalispell and Helena. Tasks 3 & 4 – Existing Storm Sewer Capacity Analysis Level of Detail: • Trunk-line sewer with simplified, grouped inlets Data Needed for Analysis: • Follow similar approach AE2S and TD&H used for the wastewater collection system model update Analysis Method: • Efficiently import hydraulic network field survey and GIS data using custom-built tool developed by AE2S • Automate runoff parameter generation using InfoSWMM subcatchment manager • Quickly summarize benefits and drawbacks using InfoSWMM’s Scenario Manager Evaluation Scenarios: • Existing, pipe improvements, and alternative approaches 2PROJECT OVERVIEW AND APPROACH AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 2.4 2 Successful AE2S Project Illustrating Coarser Level of Detail for Future Developed Areas Compared to Areas with Older Infrastructure Runoff Volume Impacts from Land Use Changes aren’t Mitigated by Traditional BMPs and can Impact Existing Downstream Infrastructure Pre-Development Post-Development HYDROGRAPH COMPARISON Increased Volume and Extended Discharge Level of Detail: Level sufficient to: 1. Determine downstream impacts (if any) 2. Size regional detention facilities 3. Develop mitigation strategies Data Needed for Analysis: • Record drawings from Bozeman Infrastructure Viewer, 2018 LiDAR, survey critical features Analysis Method: • InfoSWMM (See Section 4 for discussion on benefits and drawbacks of other modeling platforms) Evaluation Scenarios: • Existing, 10-, and 30-Year Planning Horizons Applicable Geographic Areas: West, Middle, and somewhat East (see map on page 2.1) Approach Justification: The City’s Growth Boundary extends several miles beyond the urbanized limits and the Growth Boundary is primarily classified as Urban Neighborhood, which has a broad definition and encourages high density development. Through our ongoing Wastewater Facility Plan project with you, we know for planning purposes the City is interpreting future land use to average 20 dwelling units per acre. Applying that same average land use density to the Stormwater Facility Plan, future urban land use could average 70% impervious or more. Knowing that groundwater and/ or soils often preclude widespread runoff volume reduction (LID) strategies, runoff volume would significantly increase compared to predeveloped conditions, illustrated in the hydrograph below. This increased runoff volume will drain through existing portions of the City with on-line and off-line detention facilities immediately adjacent to trunk-line drainage routes. Because these facilities are subject to backwater during high flows along the drainage-ways, there is a potential that future development, even if peaks are mitigated, will increase maintenance headaches and further compromise existing capacity on stormwater infrastructure. Therefore, as part of the regional stormwater treatment planning task, we recommend including the existing downstream trunk-line drainage in the InfoSWMM analysis. Therefore, as part of the regional stormwater treatment planning task, we recommend including the existing downstream trunk-line drainage in the InfoSWMM analysis. Existing Development (Post-1980) and Planning Horizon Area: 2PROJECT OVERVIEW AND APPROACH AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 2.5 Fringe Farm and Forested Watershed: Applicable Geographic Areas: West and Middle (see map on page 2.1) Approach Justification: These fringe contributing areas need to be incorporated to account for their ability to take up conveyance capacity in ditches and streams within the City’s drainage system. This proven approach (See City of Helena project example) will ensure we account for potential impacts from the large undeveloped watersheds upstream. 3 We provide our clients with the very best team for each project. WGM is part of our team because of their work with you to evaluate the potential for regional stormwater practices within the Valley Center area. As part of Task 4, we will further evaluate facilities in this area (and others) given the advantages this area offers for regional stormwater treatment. Advantages: Downstream of development areas Soils and geologic conditions conducive to infiltration and water quality treatment Nitrogen removal from runoff offers potential benefit to WRF via Nutrient Trading REGIONAL REGIONAL STORMWATER STORMWATER MANAGEMENT MANAGEMENT STRATEGIC STRATEGIC AREAAREA VALLEY CENTER OFFERS AN ADVANTAGEOUS AREA FOR REGIONAL MANAGEMENT Tasks 3 & 4 Deliverables: InfoSWMM Model Technical Memorandum documenting assumptions, methods, and improvement recommendations. Providing a varied level of detail throughout the City’s planning area while combining the planning area into a single model provides the City with the following benefits: A single model for the City’s drainage system, providing an adaptable system as the City expands. Comprehensive understanding of the why flooding occurs, and the foresight to avoid future flooding complaints. Ability to understand impacts of future development on downstream infrastructure, allowing the City to make sound, cost-effective decisions for both rehabilitating existing infrastructure and planning for future infrastructure needs; and Appropriate engineering investment for this Plan that can be adapted over time, as the need arises. Improvements ultimately rely on funding for completion, so we will prepare written documentation with that mindset. We can also provide the City with the same information in a GIS-based web platform to provide a living document that can be updated as improvements are made. Level of Detail: Stream and irrigation ditch hydrology based on existing land use Evaluation Scenarios: Existing only (used in all planning scenarios described in this section) Data Needed for Analysis: 2018 LiDAR, City planning horizons Analysis Method: Adjust runoff parameters for undeveloped watersheds in InfoSWMM so that runoff matches USGS Stream Stats 2PROJECT OVERVIEW AND APPROACH AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 2.6 In our approach, we’ve combined Task 5 and Task 6 because asset management, capital improvement plans, funding needs, and utility rate structures are all tightly connected. Further, these tasks need to address different types of assets within the City’s stormwater program, namely storm sewer pipes, BMPs, and drainage-ways / culverts. Regardless of the type of asset, asset management and associated funding plans are about making the right infrastructure decisions, at the right times, and for the right reasons. While there are different ways to arrive at a decision, using data-informed decisions to drive your asset management and funding plans is the most defendable approach to reducing risk when budgets are limited or questions arise from superiors, elected officials, and your community. This approach also provides value to communities like yours because risk takes on many different forms, and by using a data- informed approach, various types of risk can be weighted and ranked, all built on a foundation of defendable modeling output and asset data, instead of the ad hoc approach of responding to the loudest complainer or some other non-systematic method. Our method for using a data- informed approach to help our clients manage risk combines metrics for the Likelihood of Failure (LOF) for an asset with metrics for the Consequence of Failure (COF) if that asset fails. The LOF and COF metrics typically come from a variety of sources, such as InfoSWMM model output, your existing utility geodatabase, other GIS data, desktop reviews, and field inspections. Innovyze InfoAssetPlanner can transform your modeling results, GIS data, and inspection data into a powerful asset and risk management tool. While the specifics of the metrics will vary depending on the asset type (drainage-ways/ culverts, BMPs, or storm sewer), all the assets will incorporate at least one metric reflecting that asset’s condition, because current condition is always an indication of an asset’s future likelihood of failure. Part of our approach will be to develop a program and conduct a condition assessment of drainage-ways and culverts following these main steps since we know that the City does not currently have a comprehensive asset management program for these assets. Condition assessments for these types of assets will likely follow these main steps: 1. Establish a cursory asset condition using aerial imagery, LiDAR, and Google Street View. 2. Establish a field inspection form for drainage-ways and culverts that integrates into CityWorks so data feeding into your asset management program can be updated as new data is collected and as the asset continues to age. 3. Review InfoSWMM results to determine which assets are most likely to cause bottlenecks. 4. Further refine metrics for LOF and COF (and how significantly each is weighted) using InfoAssetPlanner to establish ranking criteria and, ultimately, prioritize maintenance. PROVEN EXPERIENCE For a previous Stormwater CIP, AE2S worked with the community to weigh numerous risk factors like traffic impacts, structure flooding, ditch hazards, pipe age and type, and many more that provided a solid foundation for their stormwater CIP. Tasks 5 and 6 – Additional Stormwater Utility Funding Recommendations, Maintenance Asset Classes, and Capital Improvements Plan (CIP) Recommendations 2PROJECT OVERVIEW AND APPROACH AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 2.7 Preliminary Risk Model Based on our experience working with other communities managing their stormwater assets, an effective asset management plan approach assembles these types of LOF metrics along with COF metrics. In fact, as part of this proposal, we have developed a preliminary list of COF and LOF criteria (see table below) for you to consider as you begin the process of building your stormwater utility asset management program – a list that we will refine as we work with you to develop a tailored plan for the City. The next step in this process involves us working with you to develop appropriate weights to each so that you have a defendable, unbiased approach to managing your stormwater assets and developing a funding and capital improvement program. Likelihood of Failure (LOF): These factors will impact how and when an asset might fail and help define the maintenance, repair, rehabilitation, and improvement approach. Consequence of Failure (COF): These factors will impact how critical an asset failure is and help you prioritize the maintenance, repair, rehabilitation, and improvement approach.

As a demonstration of what that would look like, we’ve shown conceptual results for the pre-1980s infrastructure. This demonstration illustrates two key findings: 1. A map (or web map) based approach to visualizing the combined likelihood of failure and consequence of failure allows you to clearly see where improvements should be prioritized. In other words, while the process and logic to develop a prioritization plan may be complex, a map like this distills that complexity down into actionable terms that your department, elected officials, and the community can easily understand. 2. Because we know there are likely significant data gaps in the final list of metrics to feed into InfoAssetPlanner and there may not be time or budget to fill in all these data gaps as part of this project, asset prioritization can still occur with incomplete data. Further, based on our experience working with other communities, this is completely normal and does not detract from the value of beginning to establish a framework to build on for years to come. To address data gaps in the initial asset management program, we recommend including fields within the databases noting where "condition/data verification" is needed prior to embarking on a specific capital project. Once a risk score is assigned, the next step is to develop an action plan for each asset you own. As one example, the decision flow chart that follows is an example action plan for each storm sewer pipe segment. The value of a process like this is two-fold: 1. Allows you to focus limited field investigation resources, such as CCTV equipment (if needed) in areas that have high risk so that data collection can be transformed into a focused effort versus a shotgun approach. 2. Develops an efficient and defendable approach for no action, minor repairs, pipe lining, or full replacement.

Over the past several years, AE2S has been providing added value to our clients by combining hydraulic model output with risk and financial models to develop dynamic utility operation, maintenance, and CIP tools. Once you have a defendable asset management plan and the associated capital or maintenance projects identified and costed, tracking the planned costs over time and identifying funding sources is critical to sustaining the financial health of your utility, as well as the ability to set appropriate utility rates to fund the necessary projects. We also know that City budgets are dynamic, so we have worked with many utilities to develop a dynamic, user-friendly, and web- based capital improvements tools versus only a hard copy report that will likely need to be modified soon after creation because of changing budgets or priorities. This dynamic and adaptable tool can be integrated with your existing Water Facility Plan and the ongoing Wastewater Facility Plan either soon or down the road. As a demonstration of the usefulness of having all your CIP data in one, dynamic location, we’ve input several of your current stormwater, water, and wastewater CIP projects into a web-based tool, which we’ve shown on the following page.

Customize to allow for multi-phase/multi-year projects. Customize to include any funding sources/mechanisms that are available. Easily adjust project schedule, funding sources, and cost – all while updating projected revenue requirements on the fly. Export data to most formats (including pdf). Easily use so it won’t collect dust on your shelf! Further, the tool can also help you visualize capital expenses and funding sources over time. While we recognize that the Stormwater Facility Plan will, of course, focus on the stormwater funding component, the tool can be scaled up in the future to encompass all City capital projects. We deliver understandable and concise products to our clients. As you know, we prepare graphical Executive Summaries that distill the details of a Facility Master Plan into a succinct visual summary. Our graphical Executive Summaries provide added value to a report by making it approachable to a wide audience, including technical City staff, City officials, and the public – which is crucial to providing successful utility planning. Our core value is “Extreme Client Service”, which we carry out by understanding our clients’ goals and needs and then exceeding those goals. As one of our client’s wrote, “It’s refreshing to work with a firm that is so proactive and on top of things. It seems that whatever we’re thinking, you guys have already thought the thought and have taken it another step or two beyond.” This is the level of service we pride ourselves on delivering. With our project management approach, you will never feel like your expectations are what’s actually being managed. Your Project Manager Zach brings extensive experience with Innovzye and other advanced hydraulic modeling programs. He is supported by Scott Buecker, Client Services Manager. Scott has over 20 years of municipal engineering experience and has institutional knowledge of the City of Bozeman. Zach will be responsible for day-to-day management of project tasks, and Scott will provide oversight and quality control. Scope, Scheduling, and Budget Monitoring Project progress does not always match budget progress. We will track these weekly – and when they aren’t aligned, we will make swift corrective actions. We use a progress tracking model which helps visualize completeness versus budget spent so we can make sure we are staying on track.

AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 4.1 LARGE MUNICIPALITYINFOSWMM MODELINGPROJECTS COMPLETED REGIONAL STORMWATER FACILITY PLANNING PROJECTS RESORT COMMUNITYCLIENTS In addition to the experience summary above, AE2S are experts in other modeling platforms as well. The original RFP noted that InfoSWMM would be the required modeling framework, but the answers to questions indicated a potential for some flexibility if the City sees value in a different approach. While we still believe that InfoSWMM is likely the tool that best fits the City's overall needs, we have provided you with the benefits and drawbacks to each of the modeling platforms building on our first-hand experience working with all the platforms listed below. In fact, for a large 3.7 square-mile urban stormwater facility plan, AE2S completed the analysis in both InfoSWMM 1D and XP-SWMM 1D-2D because the client’s needs and objectives changed during the project. During project scoping, we can listen to you to more fully understand your near- and long-term goals, draw on our broad experience in these platforms, and finalize our recommendation for the modeling platform to use for this Facility Plan. Modeling Framework Benefits Drawbacks InfoSWMM • Our team has unmatched experience with InfoSWMM, including with Helena and Kalispell highlighted in this section• City already has InfoSWMM License• Fully GIS-integrated• Robust ability to compare alternatives• Robust database management capability• Top-notch technical support from one of the world’s top experts in SWMM (Bob Dickinson) • 2D (if needed) is less robust compared to XP• If additional licenses are needed at the City, higher cost compared to PC-SWMM. XP-SWMM/ XP-STORM • Our staff have decades of experience using XP for municipal stormwater projects, including Burnsville project highlighted in this section.• Robust 2D modeling capability for inundation mapping • Crashes and corrupts model often• License for scale needed is about $50,000 up front plus ongoing maintenance• Difficult to compare alternatives• Clunky GIS functionality• Limited database management capabilities• Runs on old version of SWMM PC-SWMM • Cheaper than XP to purchase and maintain• Stays up to date with EPA SWMM releases (like InfoSWMM)• Good technical support for questions or issues that arise • Requires separate license that City does not already have• 2D capability (if wanted in the future or as part of this project) is less robust• Completely different interface than what City staff is likely familiar with (requiring training).

A large two-square mile area on the west side of Kalispell is planned for mixed use development. Complicating matters is that the area drains to an existing, recently- developed neighborhood that experiences frequent flooding and drainage problems. Additionally, this area contributes to West Spring Creek which has a regulatory FEMA floodplain. 2. Approximately 50 square miles of rural and mountainous watershed contribute to this developing area with a wide range of hydrologic conditions. 3. City of Kalispell standards require peak flow control for the 10- and 100-year 24-hour design storms. While Kalispell is subject to the State’s MS4 requirements that encouage runoff volume reduction, soil conditions in Kalispell preclude widespread infiltration practices. AE2S Solutions: An InfoSWMM model was developed with varying level of detail for urbanized and rural drainage areas. The model accounted for the diverse hydrology across the watersheds by adjusting rural runoff parameters so results reflected observed historic flood conditions. Our team developed several policy and infrastructure improvement alternatives to mitigate the flooding impacts from the new development. We collaborated with the City to implement a combination of regional facilities and watershed-specific peak discharge policies because pre-post discharge control was insufficient to mitigate downstream impacts. The additional detention storage needed would be a shared responsibility between the City and Developers. The recommended alternative required approximately 10% of the planned development area to be designated to regional stormwater facilities. AE2S collaborated with the City in ongoing communication with the developers and impacted land owners to help them understand the need and benefit for the recommended regional facilities. Value to the City: By using InfoSWMM to evaluate the land use change impacts and creating watershed-specific peak discharge criteria, unintentional downstream flooding impacts in a contentious community were avoided, and the City was able to back the policy change with a strong technical justification to convince land owners and developers of the need for large regional facilities. The infrastructure improvements are planned to go to bid in early 2021. As the lead modeler on the planning effort, Zach was able to smoothly transition a concept to a permitted design. 4RELATED EXPERIENCE ON SIMILAR PROJECTS AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 4.3 STORMWATER FACILITY PLANHelena, Montana DATE 2017 PROJECT COSTS $249,000 CLIENT City of Helena CLIENT CONTACTRyan Leland, PECity Engineer406-447-8433 Why This Project? • WGM - AE2S Team • Montana Stormwater Planning Project • Downstream Capacity Evaluation • Improvement Feasibility and Costing • Stormwater Planning Around Irrigation Ditches • Upstream Rural Watersheds Key Challenges: 1. The mountains south of Helena have a much larger watershed footprint to the urbanized watershed, so accurately estimating runoff from this portion of the study area was critical to providing solid recommendations for improvement. 2. While the City had a comprehensive GIS storm sewer database that had substantial information, much of the storm sewer lacked invert data. 3. The City hadn’t had a significant storm in recent memory, so there was little understanding of how the system functioned. WGM - AE2S Solutions: To accurately estimate runoff from the mountains upstream, our team adjusted watershed runoff volume and timing parameters in the InfoSWMM model so that the peaks matched the predicted flood peaks based on USGS StreamStats as well as taking into account qualitative observations from City staff. Using InfoSWMM’s tools, our team coordinated with the City staff to strategically collect invert data and leverage InfoSWMM’s data gap filling tool to efficiently fill in the remaining data gaps. Finally, our team used a simplified approach for inlet modeling that allowed us to quickly evaluate which storms and which locations street flooding was driven by inlet capacity limitations, storm sewer capacity limitations, or both. During the study, a moderately severe storm occurred, and the model showed storm sewer surcharging in locations where manholes were blown off. Value to the City: By solving these key challenges, the WGM-AE2S team provided the City with the following benefits: 1. The model correctly estimated the runoff draining from the mountains so the resulting facility plan had “right-sized” storm sewer improvements instead of a plan with oversized facilities, which would have costed the City more money. 2. Since funding for the project was constrained, the City was able to get the most value for the dollar by obtaining a useful stormwater facility plan for the entire City. 3. The City was able to obtain a comprehensive understanding of the system that matched recent observations so that the City could focus their future capital expenses on necessary improvements. 4RELATED EXPERIENCE ON SIMILAR PROJECTS AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 4.4 CITY-WIDE 2D STORM SEWER SYSTEM MODEL, RESILIENCY STUDY, AND LAKE LEVEL ANALYSIS Burnsville, Minnesota CLIENTCity of Burnsville CLIENT CONTACTJen Desrude, PECity Engineer951-895-4544 DESIGN YEAR2019 - Present KEY PROJECT ELEMENTS• Large-Scale XP 2D Modeling• Flood Risk Assessment• Prioritized Improvements Why This Project? • City-wide stormwater model • Identify existing system deficiencies • Use Risk Assessment to prioritize improvements • XP-SWMM (if City decides this platform is the prefered software) Key Challenge: The City of Burnsville operates a 27-square-mile footprint of storm sewer, ditches, natural channels, and ponds. A network of connected stormwater and natural ponds serve as water quality treatment and flood control, but the City lacked a comprehensive understanding of which facilities were critical and what portions of the City were most vulnerable to flooding. AE2S Solution: We developed a 2D-XPSWMM model at the catchbasin level. The City-wide 2D model provided rapid inundation mapping and flood-depth rasters. These results along with other hydraulic metrics and geospatial data were used as inputs for a custom-built risk assessment tool that assigned weights to various likelihood of failure (LOF) and consequences of failure (COF) metrics. Value to the City: Creating a comprehensive City- wide stormwater model only provides value if the outcome bears insight on laying a path forward. Our custom risk tool digested complex model results and geospatial datasets into a simple list of zones to allow the City to prioritize improvements and have a defendable basis for the ranked priority of each flood-risk area throughout the City. Our Team is proceeding with preliminary and final design for major pond improvements in a zone categorized as high vulnerability. The design elements of these pond improvements aren’t complex or costly but the City may not have realized this opportunity for low- hanging fruit without our in-depth analysis. 4RELATED EXPERIENCE ON SIMILAR PROJECTS AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 4.5 Key Challenges: Facility plans often stall prior to making the plans a reality because communities lack the necessary funding. Other communities have been able to commit the funds to construct large capital projects but then find themselves with depleted financial reserves that hamper their ability to provide operation and maintenance costs so that the new assets reach or exceed their design life. These challenges create “funding gaps”, and they can be caused by a number of factors: Deferred maintenance, poorly planned rate structures, quickly changing market demands, and fast-paced growth, just to name a few. AE2S Solution: Dedicated Financial Services Many years ago, AE2S recognized these challenges that many of our clients face. Therefore, to help our clients plan for all life stages of their current and future assets, we invested in growing a team of financial experts, AE2S Nexus. Those experts were put to the test in Western North Dakota during the Bakken Oil Boom during the last decade. We helped these communities understand the impacts created from the lack of funding: funding shortages that sometimes exceeded $100M. More recently, we helped both the City of Belgrade and the Big Sky Water and Sewer District understand what funding they have in place for their wastewater plant expansions and how they can address the gap created by the unpredictable construction market in the Gallatin Valley. AE2S Solution: Building the Rate Structure that Works Best for Bozeman Stormwater rate structures can be simple or they can be complex , but there’s no single best rate structure for a community. Moreso, it’s driven by what you want to accomplish. We have helped a number of communities build the right rate structure for them - from establishing a brand new utility, to overhauling the structure, or to set the right rate using their existing structure. For example, Jamestown, ND needed help to establish a new rate structure and through the process, we worked to incorporate feedback from staff and council on appropriate ways to charge both residential and commercial properties with their varied impacts on stormwater infrastructure. In Fargo, as the demands of the utility grew, the complexity of the rate structure needed to grow to make sure that the appropriate revenues were being generated to continue meeting the ongoing O&M needs of the utility. Finally, in Sioux Falls, we are asked on an ongoing basis to review their storm drainage rates and help verify they are on track to fully fund their utility’s ongoing operations. In addition to all the help we provide our clients with stormwater utilities, each year, AE2S assembles a comprehensive rate survey for communities across numerous states. The 2020 AE2S Rate Survey included over 250 communities, including communities throughout Montana. You can rest assured that by selecting AE2S, you will have the best financial experts at your disposal. AE2S Solution: Setting Impact Fees to Equitably Spread Costs Across New and Exisitng Development Rates alone are often insufficient to address large funding gaps, particularly when a community is facing fast-paced growth, as Bozeman is currently experiencing. In those instances, we have helped to review and update what the local equivalent of an impact fee is. In Billings, MT, we have updated the impact fees for their water and wastewater utilities since 2014, specifically calculating fair and equitable amounts for both new developments and large, unique users looking to connect. Similarly, we have assisted the City of Sioux Falls, SD in reviewing their storm drainage platting fee (impact fee equivalent) to ensure that the approach to incorporating in-basin and out of basin credits is fairly applied. AE2S Solution: Bringing the Whole Financial Picture into Focus While rates and impact fees are the core ways and methods to evaluate your overall capital needs and fairly recoup them, we can also assist in identifying other alternatives, whether through special districts or permit fees, grants, or any number of means that may offset costs to your citizens and businesses. Value of Dedicated Financial Services and Engineering Services Under One Roof In all situations where clients turn to AE2S for engineering and planning and to AE2S Nexus for financial expertise, we provide value to our clients by making sure big plans aren’t just pie in the sky dreams - they are big dreams with a financial plan to transform them from a dream to a reality. COMBINED EXPERIENCE OF AE2S NEXUS The Financial Link 4RELATED EXPERIENCE ON SIMILAR PROJECTS AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 4.6 ASSET MANAGEMENT TOOLSVarious Cities Key Challenges: Historically, extensive infrastructure investment decisions had to be made from institutional knowledge and often times by gut feel. However, with the financial cost for improvements requiring that projects be stretched out over years or decades, making smart choices on which projects can increase the benefit to the citizens and businesses by reducing risk quicker. Further, we recognize that plans change, needs change, and priorities change, so asset management and capital improvement plans that are static can quickly become outdated. AE2S Solutions: AE2S is at the forefront of leveraging rapidly evolving technology and data availability to help utilities take a much different approach to capital planning than in the past. Many utilities can now fortify this decision-making process by relying on detailed records of what’s been done in the past, and failure probability models to estimate what is most likely to need immediate rehabilitation. KEY PROJECT ELEMENTS• Risk Assessment • Asset Prioritization• Actions Based Recommendations • Budgeting• Dynamic Risk Model In the past five years alone, we have helped Fargo ND, Bozeman, Helena and Kalispell MT, Eagle River Water and Sanitation District (Vail CO), and Eagan, Burnsville, and Plymouth MN develop “smart” capital improvement plans that incorporate historical failure records and current condition assessments to develop prioritized asset rehabilitation programs. Many of these asset rehabilitation programs include risk models that help prioritize assets based on their work order history from CMMS platforms, NASSCO-coded CCTV inspection data, visual condition inspections, and many other quantitative metrics that contribute to the likelihood or consequence of asset failure. Value from AE2S Solutions: By developing a matrix that combines the likelihood and consequences of an asset failure, we are able to help our clients reduce overall risk quicker by prioritizing extreme risk assets, followed by high- and medium-risk assets in a methodical manner. This logical approach to asset management provides the stormwater program a defendable approach to other city departments, elected officials, and the community for the sequence and timing for planned improvements. The dynamic aspect of these smart capital improvement plans has helped our clients shift into a mindset of continually updating their risk models and subsequently, always have a current capital improvements plan.

The City as an MS4 is obligated to inspect and maintain these BMPs. However, despite newer BMP technologies like filtration and underground BMPs being constructed in the City, the City lacked an understanding of how to maintain these newer types of BMPs. Further, while the City has a comprehensive GIS storm sewer database that had substantial information on when maintenance occurred, the City does not track BMP condition or specific maintenance activities, which created challenges since BMP maintenance is spread out amongst multiple City departments. Finally, several BMP maintenance projects were not received well by residents and lack of documentation about the why behind maintenance put City staff and the Council in a difficult position. AE2S Solution: Our team reviewed other cities’ and states’ BMP maintenance plans to create a maintenance plan template. Our team led a series of review meetings with City staff to customize the maintenance plan template to meet the City’s goals and capacities. This became the Woodbury Stormwater BMP Maintenance Plan. In coordination with City staff, our team identified the cost needed to perform minor and major maintenance of each type of BMP. Using that unit cost data, our team prepared an overall cost estimate to implement the Plan. Value to the City: The City is able to use the maintenance guide when reviewing proposed new BMPs during their development review process. With the cost data, the City is able to identify if changes to their stormwater utility fund are needed to support new staff, equipment, and projects. Finally, the City has a guiding document to use when they engage with residents. 5PROPOSED SCHEDULE AE2S BOZEMAN 2021 STORMWATER FACILITIES PLAN UPDATE PROPOSAL 5.1 We have laid out a conservative schedule starting in March 2021 with completion in October 2021.
