INTRODUCTION 1.1 Triangle Description Since 2010, Gallatin County has been one of the fastest growing counties in the State of Montana. According to the U.S. Census Bureau, Gallatin County’s population was 67,831 in 2000, 89,513 in 2010, and was estimated to be 111,876 in 2018, the latest year for which population estimates are available. With an estimated 22% population growth for the time period between April 1, 2010 and July 1, 2018, Gallatin County was listed as the 36th fastest growing county in the U.S. It has taken from the mid-1800s until 2015 for the County’s population to reach approximately 100,000 people, but if growth continues at even a modest 2.75% annual growth rate, Gallatin County will reach a population of 200,000 by 2040. With population growth and fast-paced land development, the Triangle area of Gallatin County, which is loosely described as the area between Bozeman, Four Corners, and Belgrade, is experiencing change. The Planning Coordination Committee (PCC) has developed the Triangle Community Plan to coordinate land use development patterns, deliver community services and infrastructure, and protect important environmental resources, all in a manner that supports community values and vision while responding to rapid growth pressures. 2 1.2 Triangle Community Plan Boundary Map See map at: http://gis.gallatin.mt.gov/webmaps/?map=pcc&lat=45.73150&lon=- 111.13762&scale=577791&l4=a Figure (1) – Triangle Community Plan Boundary Map The plan boundary is: The Gallatin River to the West, Frontage Road to the North, Fowler Avenue to West Garfield Street to South 19th Avenue to the East, and Blackwood Road to Four Corners Water and Sewer District to the South. The Four Corners Water and Sewer District and Utility Solutions are in the process of adjusting the service district on the southwest boundary. The PCC agreed that the south boundary should follow the service district boundary. This will be updated when finalized. 3 1.3 Existing Conditions Currently, the Triangle is a mix of all land uses and represents the transition and tension between the old West and amenity rich new West. The “old West” is typified by an economy dominated by natural resources and agriculture, with disperse, rural development patterns, while the “new West” has a diverse economy focused on the service industry, technology and non-earned income with growing towns adjacent to outdoor recreation opportunities. Currently, open spaces and agricultural operations in the Triangle support a local agricultural economy that is diverse. Agricultural operations support dairy and beef cattle, hay production, grain crops, local market vegetable produce, and other specialty products. The Gallatin Valley values its agricultural heritage and also embraces local food production and new emerging agriculture markets. With rich soils and irrigation infrastructure developed over the past century, the Gallatin Valley is positioned to continue its leadership in production and innovation. The commercial expansion in the Triangle area over the past few decades has supported and diversified the local economy and responded to the changing needs of the population. From industrial warehouses to retail to growing local businesses in technology and recreation, the Four Corners area and nodes along Huffine and Jackrabbit continue to be desired commercial locations and emerging community hubs. In addition, there are commercial gravel mining operations in the north end of the Triangle that are sources of economic activity. Residential developments and larger, multi-phase subdivisions continue to populate the Triangle. The diversity of developments offers different housing options to the market from large country estate lots to multi-family housing. The Triangle is rich in natural resources, most notably the Gallatin River, its’ tributaries and wetlands. The aquatic resources of the Triangle are important fish and wildlife habitat but also contribute to recreation opportunities and the high quality of life connecting to the natural world that residents value. 1.4 Jurisdictional Overlaps and Existing Zoning Districts The Triangle Community Plan is an area that has many different and overlapping districts, land uses, and ownership. There are currently four (4) existing Zoning Districts within the Triangle boundaries, each with established rules and regulations that guide development in those areas. All lands within the Triangle Plan Boundary would be subject to the plan. There are however, properties that, due to conservation easements, deed restrictions, or other land use controls, have defined uses and therefore would not likely see a use change under the adoption of the Triangle Community Plan. 4 Figure (2) identifies the following areas on the Triangle Community Plan map. a) Four Corners Zoning District b) Gallatin County/Bozeman Area Zoning District c) Zoning District #1 d) River Rock Zoning District e) Belgrade and Bozeman City Boundaries f) Belgrade City-County Planning Jurisdiction g) Bozeman Community Plan Boundary h) Conservation Easements i) Public Lands j) MSU Lands Figure (2) – Triangle Community Plan Map Page 5. 5 6 1.5 Organization of the Plan The Triangle Community Plan is organized as follows: Section 1 provides a description of the planning area and existing conditions. Section 2 offers a brief history of the Plan, the approach, and the jurisdictional coordination. Section 3 focuses on the vision and guiding principles, as well as identifying some of the key issues in the Triangle area. Section 4 are the goals and policies of the Plan. Section 5 outlines next steps, including adoption and implementation. Section 6 provides definitions. 7 2. HISTORY, APPROACH, AND COORDINATION 2.1 A Brief History The creation of the PCC was one of the recommendations that came from a document called the Gallatin Triangle Planning Study, conducted by Sanderson Stewart in 2014. The Gallatin Triangle Planning Study was conducted in response to the population growth trends of Gallatin County. The study focused on opportunities for intergovernmental cooperation involving issues around infrastructure, land use, and public services. The study concluded with four recommendations to support regional cooperation. 1. Create a Planning Coordination Committee with representatives from Belgrade, Bozeman, and Gallatin County. 2. The PCC could support efforts to; create a common portal of information, support communication and updates regarding policies and projects, learn from other communities about regional planning, and work with Montana State University on Envision Scenarios to illustrate outcomes of various planning approaches. 3. Review and update Growth Policies and adjust elements that are in conflict or do not support current vision of the area. 4. Increase community participation and citizen engagement in planning and visioning. 5. Continue evaluation of specific topics that warrant more in depth analysis including wastewater, transportation, and community services like fire protection and schools. The PCC was formed in August 2016 to provide a forum for planning related coordination. The PCC was established through a Memorandum of Agreement (MOA) that outlined the need for coordination and communication between the City of Bozeman, the City of Belgrade, and Gallatin County, to support growth and development patterns as they expand in this area of the Gallatin Valley. The MOA identified issues around infrastructure, public safety, parks and trails, neighborhood design, and other land use concerns that would benefit from cooperative planning. The MOA dictates that the PCC shall be advisory in nature only, without any authority over planning-related decisions in any of the participating jurisdictions. The PCC is comprised of 3 representatives from each jurisdiction: a commissioner, planning staff, and planning board member. 8 Jurisdiction Commissioner Planning Staff Planning Board Member Belgrade Kris Menicucci Jason Karp Elizabeth Marum Bozeman Chris Mehl Chris Saunders Lauren Waterton Gallatin County Don Seifert Sean O’Callaghan Randy Visser 2.2 The Planning Process and Approach From 2016-2019, the PCC has held over 24 meetings and explored the following subject areas: water and sewer, fire, sheriff and police, the development of MPOs, agriculture, irrigation infrastructure, parks, trails and recreation, schools, transportation, water resources, and community health. The PCC meetings have also provided opportunity for consistent updates from each community. These updates ensure there is good information exchange and understanding of activities going on in each jurisdiction. The improved communication between the jurisdictions that has resulted from the PCC meetings has produced these products: 1. Interactive mapper hosted by Gallatin County (http://gis.gallatin.mt.gov/webmaps/?map=pcc ) that supports decision making and information sharing. 2. Vision statements that can be incorporated Section 3.1 of this plan. 3. Communication and Coordination plan that is outlined in Section 2.3 of the Triangle Community Plan. 4. Overview of planning approaches to support discussions of the PCC. 5. MOU between Bozeman and Gallatin County (draft 12/2019). 6. The Triangle Community Plan. The PCC sponsored numerous opportunities for public comment on the draft Triangle Community Plan. The plan was available on the Gallatin County website and offered online comment submittal. Press releases were distributed to area newspapers and news stations and the PCC published an Op Ed in the Bozeman Daily Chronicle. The PCC hosted four open houses and had over 80 participants attend. Presentations were also made to Planning Boards and Commissions. The public comment received was diverse and detailed and overall very supportive of the plan. Final edits were made by the PCC in response to the public comment and community engagement efforts. 9 2.3 Inter-Governmental Coordination and Communication Plan One of the primary goals of the PCC is to support and participate in regular communication between elected officials, staff, public, and planning board members on various planning issues, in order to stay informed and identify opportunities for collaboration. Coordination and communication between the various jurisdictions is vital to maintaining administrative efficiency and quality of life for all residents in a rapidly changing landscape. The PCC benefits from information and input from a wide range of outside entities (e.g. water and sewer districts, emergency services, schools, airport, chamber of commerce, nonprofits, realtors, etc.), and may invite them to participate in work sessions or to participate in ad hoc committees to develop recommendations. Invitations to participate in PCC meetings, updates about PCC activities, and press releases to local media outlets will be executed on an as needed basis. The PCC established the goal to produce a single plan through the joint effort of the three jurisdictions. The plan will be adopted under the Growth Policies of Belgrade and Gallatin County. The plan will also be referenced in Bozeman’s Community Plan. Each of these plans includes a section on how the local entity will interact with other regional plans and coordinate with local, neighboring entities. The PCC recommends the Triangle Community Plan be implemented and supported by the following communication efforts:  Annual Planning Board Roundtable with planning board members from Bozeman, Belgrade, Gallatin County, Manhattan, Three Forks to provide inter- jurisdiction communication on activities and coordination opportunities;  Elected Officials from Belgrade, Bozeman and Gallatin County host an Annual Land Use Roundtable to discuss projects, issues, legislation, and related issues;  Capital Improvements Plan and Infrastructure Plan Annual Roundtable, where staff and elected officials from Belgrade, Bozeman and Gallatin County review plans and update maps and / or annexation zones; and  Coordination on future Metropolitan Planning Organization (anticipated after the 2020 census). The Triangle Community Plan was developed with a focus on coordination between jurisdictions and to provide a seamless transition between existing plans necessary to achieve the vision. It does not intend to abrogate the growth policies of Gallatin County, Belgrade, or Bozeman, or adversely affect the existing neighborhood plans and zoning districts. Every 12-24 months the PCC will evaluate opportunities to improve the PCC functions and structure. The PCC will also evaluate and update the PCC By-laws and other agreements to ensure the necessary flexibility to improve the PCC as needed. 10 2.4 Authority Authority of this community plan is authorized by Montana State Statute and the Gallatin County Growth Policy. Section 76-1-106 of the Montana Code Annotated (MCA) requires local planning boards to prepare Growth Policies, and Section 76-1-601 offers general guidance for the contents of a Growth Policy and/or Neighborhood Plan. Sections 76-1-602 through 76-1-604 gives the procedure for adoption of Growth Policy or Growth Policy Amendment. Additionally, Chapter 4.3 of the Gallatin County Growth Policy authorizes the development of Neighborhood or Community Plans throughout Gallatin County. Those community plans must be drafted in compliance with the County Growth Policy, and are designed to give greater specificity within a certain defined area. 11 3. VISION, VALUES, AND KEY ISSUES 3.1 Triangle Plan Vision Regional coordination creates and maintains a coherent land use pattern that supports the needs of existing and future citizens and the desire to protect community character and amenities. Cooperation between jurisdictions supports development patterns that do not compromise the ability of municipalities to grow in the future or expand necessary infrastructure. Belgrade, Bozeman and Gallatin County will coordinate land use in the Triangle to achieve: Compact, contiguous development and infill to achieve an efficient use of land and infrastructure, reducing sprawl and preserving open space, agricultural lands, wildlife habitat, and water resources; Well-planned transportation systems, consistent with the overall growth management vision, support the development of multi-modal and public transportation networks; Community core that have adequate transportation, utility, health, educational and recreational facilities. Residential areas that provide healthy surroundings; and Opportunities for agriculture, industry and business, while minimizing conflict between adjacent land uses. 3.2 Guiding Values The PCC believes that the health, safety, and quality of life of our citizens is the number one value driving the vision of the Plan. In addition to this overarching value, the PCC has identified a list of additional values that support the vision for the area and guide policymaking:  Transparent communication  Intergovernmental coordination  Financial responsibility, including efficiency and cost effectiveness  High quality public services  Accessible amenities and services  Walkability  Connectivity  Agricultural heritage 12  Open space and views  Recreation and opportunities for healthy activities  Safety and public health  Environmental health 3.3 Key Issues of the Triangle Plan The policies for the Triangle Community Plan were developed with consideration of the following key planning issues: LAND USE General As the population of the Triangle area continues to increase, implementation of land use policies that are consistent with the vision statement of the Plan is a vital step to ensure the Triangle is developed in a manner that provides for both current and future populations that live, work, or recreate in the Triangle. The Four Corners area continues to grow, as it is a location in which land values are still lower than within the City of Bozeman, partly due to a lack of infrastructure and services, but this is changing. Four Corners is also becoming a bedroom community for employees of the Big Sky area economy. Development pressure is also evident around Bozeman, particularly on the west side of the City (east side of the Triangle), where the construction of Gallatin High School will only serve to exacerbate those development pressures. Belgrade’s growth is in part due to being a slightly more affordable place to develop; similar to Four Corners, though that is changing rapidly as housing prices in Belgrade continue to rise. Other factors that contribute to development pressures in the Triangle include access to three major transportation corridors (Huffine, Jackrabbit, and Interstate 90), which make vehicular movement to each major point on the Triangle relatively efficient. There is still a lack of transportation infrastructure in the heart of the Triangle, where agriculture uses make up a large portion of the landscape. It should be noted that the Triangle could potentially maintain significant agricultural character for a very long time, depending on how much density and infill the communities around the Triangle are willing to accept and encourage. As laid out in the “Fiscally Efficient” growth scenario in the 2014 Triangle Plan Study, high-density growth directed into Bozeman, Belgrade, and the Four Corners area would protect large amount of open space and agricultural land in the Triangle, not as a primary goal per se, but as a secondary benefit of developing in a fiscally responsible way that minimizes long-term infrastructure liabilities. 13 The land use policies in this Plan support a vision of a coherent land use pattern that is compact and contiguous, maximizing the efficient delivery of infrastructure and other services by clustering development in established community cores, rather than facilitating development patterns that unnecessarily consume open space and agricultural land. The policies also attempt to strike a balance between encouraging developments to connect to water and sewer, while at the same time not encouraging the unnecessary extension of water and sewer service to projects that are not in line with the vision of compact and contiguous development patterns. Ultimately, the policies in this document aim to a) provide opportunities for sensible development in the parts of the Triangle where development patterns are already taking shape and currently served by infrastructure, and b) protect valuable agricultural land and open space in the heart of the Triangle where development goes against the vision of a contiguous land use pattern and is impractical and costly from an infrastructure service standpoint. Agriculture in the Triangle may not be preserved forever, but the policies in this plan discourage premature development of land before sufficient infrastructure is available to serve it and before sufficient density has been achieved in areas of the Triangle where development patterns are already taking place. Agriculture Consistently, community and neighborhood plans identify how protecting and maintaining the agricultural heritage and current production are important elements that contribute to our high quality of life. Agriculture is important contributor to our local economy, local food production, open spaces, scenic views, fish and wildlife habitat, and community identity. The Four Corners Community Plan, Bozeman Community Plan, Gallatin County Growth Policy, and Belgrade Growth Policy identify the following goals in regards to agricultural lands:  Support development standards that protect agricultural activities  Control of domestic animals  Maintain agricultural fencing  Protect of agricultural water user facilities, ditches, and water rights  Encourage protection of surface water and groundwater resources critical to agriculture  Support development standards that protect agricultural activities from incompatible land uses  Identify agricultural, wildlife and hydrological resources for conservation  Preserve farmland, open space and East and West Gallatin Rivers  Protect and preserve natural resources The Triangle Community Plan recognizes that future agricultural operations may have different scales and crops, and will benefit from the soil and water resources in the Triangle area. As mentioned above, prioritizing and encouraging development practices 14 that lead to infill and denser development near infrastructure services will not only reduce costs associated with building and maintaining this infrastructure, but will help reduce the premature conversion of agricultural land to development, thereby protecting valuable agricultural land and open space as a secondary benefit. Open Space Providing for parks and open space is accomplished through local government planning and coordination, as well as through partnerships with local nonprofits and other community partners. Consistently, community and neighborhood plans identify open space and parks as highly valued amenities and resources, from recreational uses, to viewshed protection, to the ecological services provided by these natural environments. The Four Corners Community Plan, Bozeman Community Plan, Gallatin County Growth Policy and Belgrade Growth Policy identify the following goals in regards to open space:  Establish and support plans and policy for parks, trails, and open space systems that integrate with other area planning documents.  Establish open space, parks and trails along the Gallatin River and other waterways.  Establish of setbacks along the Gallatin River and other waterways.  Provide viable parks and trails, with plans for long-term maintenance.  Protect wildlife corridors and habitat.  Preserve farmland, open space, and protect the East and West Gallatin Rivers.  Identify and conserve agricultural, wildlife, and hydrological resources.  Identify, protect, and preserve natural resources for future generations.  Provide a diversity of recreational facilities, activities, and parks. Housing Housing affordability has become an increasingly important issue, not just in Bozeman, Belgrade, and Gallatin County, but across the country. As Gallatin County continues to grow, affordability is a pressing challenge. Offering a variety and adequate rentals and ownership options can be supported through thoughtful development patterns that include a variety of housing types. The policies of this plan will need to balance the needs of constructing additional dwelling units at affordable prices, while doing so in a way that avoids and/or mitigates impacts from this additional residential development and encourages land use patterns that do not contribute to sprawl, increased infrastructure service costs, emergency service liabilities, and premature conversion of agricultural land and open space. Schools Our growing community will require additional schools to serve the students of Gallatin County. The Triangle is likely to see several new schools built in the next 10-20 years. 15 Serving students requires infrastructure, complete streets, and safe routes to school. School planning also requires coordination between the school district, private school organization, and local government to avoid and/or mitigate issues around traffic, connectivity, and safety, and to ensure that neighboring land uses are aligned properly. Public Health The PCC discussed how to best support public health in the Triangle Community Plan and agreed that rather than identifying a separate section on public health the entirety of the plan aims to promote and encourage land use and development patterns that support public health. For example, walkable neighborhoods and trails to local parks or community core areas support the physical, social, and mental health of people in the communities where they live, learn, work and play. The plan also promotes equity and equal access to community assets supporting everyone’s opportunity to attain their full health potential regardless of social position or circumstances. This holistic approach to healthful living supports the physical, social and mental well-being of our population. INFRASTRUCTURE AND EMERGENCY SERVICES Infrastructure is a critical component of the Triangle. The careful and sensible development of its network is a central focus of the Triangle Community Plan. As the area grows, it is important to provide high quality infrastructure and emergency services. The goals and policies of the Plan work together to ensure that the extension of public services and infrastructure results in a connected grid that supports the efficient use of taxpayer dollars and promotes areas of density, resulting in the conservation of important natural resources and open space. Transportation There is a dynamic relationship between transportation infrastructure and land use, each affecting the other as development and infrastructure projects are implemented. The PCC recognized that in some areas, maintaining a connected 1 mile and ½ mile grid system with extensions to existing collectors was an important goal for delivering essential services, expanding infrastructure when the time comes, and managing increased traffic. The Triangle area is also anticipated to be included in the future Metropolitan Planning Organization (MPO) after the 2020 census. Transportation network plans are detailed in Bozeman, Gallatin County, and Belgrade plans, and are important to consider in the Triangle Community Plan as well. The goals and policies in this plan encourage future transportation planning and infrastructure that will support the existing transportation plans of Belgrade, Bozeman and Gallatin County, and will help set the stage for the future MPO. The PCC also recognized the important role the Triangle Community Plan can play in ensuring a safe, connected, non-motorized transportation system. The PCC utilized the expertise and insights of local government departments and community partners to 16 create policies that support both motorized and non-motorized transportation systems in the Triangle. Non-motorized transportation systems will be a priority and developed at three levels: neighborhood trails that connect locally to parks and open space; connector trails that connect together meaningful destinations, such as neighborhoods, schools, and hubs of commercial activity; and commuter pathways that connect larger community nodes, such as Belgrade to Four Corners along Jackrabbit, and Four Corners to Bozeman along Huffine, and Belgrade to Bozeman along Frontage Road. Trail systems strive to provide maximum connectivity and serve different purposes and users. For example, transportation trails are often connecting community hubs with separated paved surfaces, while neighborhood recreation trails may access natural areas on gravel for walking and bird watching. Lastly, it should be noted that trails also add to the value of private lands, as more property owners seek out these amenities and like to be connected to their neighborhood/communities in a non-vehicular way. Water and Sewer The existence and development of public and private water and sewer infrastructure will be a driving force in future development patterns. Not only will water and sewer services direct where public and commercial developments are located, but will likely drive housing density. The cost of extending water and sewer services is an important factor in deciding where and how far these services are extended. Those cost factors should also drive hook-ups at higher densities, in order to maximize the efficient use of taxpayer dollars. In addition, overstretching these services through rapid expansion without the consideration of long term maintenance liabilities is something this plan seeks to address and discourage. There are numerous concerns in the Triangle that drive the goal of increasing the number of households, businesses, and public institutions serviced by public water and sewer systems. The goals and policies of the plan encourage providing infrastructure that supports compact and contiguous development patterns, and minimizes the installation of new septic systems and wells for environmental health reasons. Water quality is another important consideration, and wastewater treatment is linked to the protection of water quality. Septic systems threaten water quality if they fail or are placed in location that has high ground water or substrates that are extremely porous. Belgrade’s water source is groundwater that is pumped without treatment directly into the distribution system, thus maintaining water quality is critical. These conditions may contribute to the need to explore establishing a groundwater protection area in the future and Montana law provides opportunities for inter-governmental agreements to establish source water protection. The development of source water protection would be a critical step in planning for potential public wastewater treatment in the future. The Triangle will protect water resources and public health and safety by 17 maximizing future hook ups to public wastewater systems as the best approach to maintain water quality and manage nitrate levels, provided that expansion of these services are happening in a way that is consistent with the vision of compact and contiguous land use patterns. Emergency Services Community safety, health, and quality of life depend in part on the delivery of essential services. The PCC identified the goal of maintaining a minimum existing level of service to the Triangle area, and The Triangle Community Plan strives to provide residents a consistent level of service from emergency providers. This level of service is measured in a variety of ways, including emergency response times, ratio of public safety officers for the population, safe and maintained roads, snow removal, and other metrics. By engaging community partners in discussions about community development, the PCC integrated realistic and important goals and policies that reflect the recommendations of fire districts, police and sheriff, public health officials, and citizens. ENVIRONMENT The Triangle area has many unique resources and conditions that support the quality of life that residents value. The PCC recognizes that these resources deserve special consideration as growth and change affect the Triangle. Protection of natural resources, including but not limited to, water quality and quantity, wetlands, and wildlife and wildlife habitat, was recognized in conversation with community partners, PCC members, and the public. It is also important to recognize of the role of private lands in active agricultural production as land uses that provide open space, wildlife habitat, and viewshed protection. While not publicly accessible, they add to the quality of life we all enjoy. Policies that support the protection of these resources, as well as policies that address potential hazards, such as flooding, wildfire, and other environmental issues, are not only central to the vision of the Triangle Community but support the Gallatin Valley economy and quality of life. Lastly the PCC encourages the use of green infrastructure, which provides cost-effective public safety and supports valued resources including water, fish and wildlife habitat and scenic beauty. Water Resources and Wetlands The Triangle area is rich in water resources supporting residents, agriculture, fish, wildlife, recreation and our local economy and community health. Protecting these resources, most notably the Gallatin River, its tributaries and wetlands, is a top priority for Gallatin County as the benefits ripple beyond the properties in the Triangle. The aquatic resources of the Triangle are of critical importance to agriculture, agricultural irrigation, fish and wildlife habitat, and maintenance of groundwater health. Those resources underpin the recreational opportunities and the high quality of life that resident’s value. 18 Increasing demands on our finite water resources and trends of decreasing water quality call for careful management and protection measures. Because of this, the PCC encourages and supports on-going groundwater monitoring by the Bureau of Mines, the Gallatin Local Water Quality District and others. In addition, the PCC encourages and supports ongoing efforts to monitor water through Montana Bureau of Mines and Geology sponsored programs, such as the Groundwater Information Program and Surface Water Management Program. Wildlife and Wildlife Habitat Montana is rich in wildlife, and it is one of the natural resources that arguably sets our state apart from others. The Triangle area is no exception. As humans continue to influence the landscape, it is important to identify and understand the impacts of our activities on wildlife and their habitat. Utilizing informational resources available, such as wildlife migration/habitat maps from land agencies like Montana Fish, Wildlife, & Parks, will help guide best practices in how to grow and develop in a way that is sensitive to these important resources and avoids and/or mitigates potential impacts. Hazards The Triangle area is place where growth will likely occur, but there are known risks to developing in this area. The mix of residential, commercial, and agricultural activities in the Triangle offer complexity and opportunity when reducing risk and ensuring safety. It should be noted that hazards extend beyond the Triangle boundaries, and therefore it is important to identify the areas of overlapping management and response. With the goal of keeping residents safe and maintaining the quality standards of our natural resources the Gallatin County Hazard Mitigation Plan (2018) analyzes different risks and outlines response and mitigation efforts. In addition to the standards enacted by Gallatin County, Bozeman and Belgrade have plans that identify hazards and address their potential impacts to floodplains, irrigation conveyance systems, water quality, erosion, dam inundation, and groundwater. 19 4. GOALS AND POLICIES As with Section 3.3 “Key Issues,” this section is broken down into three major topic areas: Land Use, Infrastructure, and the Environment. Within each major topic area are subsections with goals and policies. Some subsections have more than one goal.

ADOPTION AND IMPLEMENTION OF THE PLAN 5.1 Adoption The plan will be adopted under the Gallatin County Growth Policy, as well as the Belgrade Growth Policy, which covers both the City of Belgrade and the shared Belgrade City/County planning jurisdiction. The Plan will also be referenced in Bozeman’s Community Plan. Each of these plans include a section on how the local entity will interact with other regional plans and coordinate with local, neighboring entities. 5.2 Implementation As a neighborhood plan, this establishes policies that are consistent with the Growth Policies of all jurisdictions and will be implemented through a variety of means. These policies carry substantial weight, and should inform development regulations and standards that will serve as review criteria on subdivision applications, rezoning applications, infrastructure development, transportation projects, school locations and other planning projects. 5.3 Updates and Status Reports The Triangle Community Plan was developed with a 20 year planning horizon. The PCC should treat the plan as a living document, and review the Triangle Plan at least every 5 years, including considerable public outreach and participation. It should be updated and revised to respond to community changes and other neighboring and associated plans (transportation, capital improvements etc.). In order to track the effectiveness of the Plan and to identify the possible need to update goals or policies, members of the PCC will be encouraged to submit annual status reports on policy implementation. 30 6.
