Overview Northwest Crossing (“NWX”) is a unique and vibrant community located in northwest Bozeman. This 160-acre master-planned community provides a diverse mix of residential and commercial uses designed around a system of pedestrian pathways and interconnected parks which highlight the natural amenities created by the two watercourses which traverse the site. The development within NWX is intended to create a cohesive community through the overall design objectives carried out in the architecture, building placement, landscaping, streetscape, and site furnishings. B. Intent It is the intent of these Design Guidelines to set the standards for the planning, design and construction of all development within NWX. All entities will use this document as a set of guidelines for creating a quality development. Any un-met code provisions, or code provisions that are not specifically listed, does not in any way create a waiver or other relaxation of lawful requirements of the Bozeman Municipal Code or Montana State law. C. Applicability The Site and Landscape Design Guidelines apply to all development within NWX in the public realm. These guidelines serve to ensure a cohesive, integrated and functional network of connectivity, infrastructure, streetscapes, parks, and gathering spaces. The NWX-Commercia/Multi-Family Building Design Guidelines establish the overall unifying themes to be followed for commercial, office, mixed-use, and multi-family development within NWX located within Planning Areas A, B, C, D, E, M, and N and any subsections thereof. Design guidelines for single-family attached and detached development will adhere to the applicable requirements set forth in the City of Bozeman Unified Development Code (“UDC”) for the underlying zoning district as well as in the NWX Residential Design Guidelines which will be incorporated into the Covenants, Codes, and Restrictions (CC&Rs). Provided the overall intent is still met, flexibility in the administration of these guidelines is encouraged in order to allow for NWX to respond to market conditions and evolve in a manner that enables development to adapt with future trends in design. D. Relationship to the City of Bozeman Unified Development Code The vision for NWX centers on the two underlying zoning districts; “Community Business -Mixed” (B-2M) located in the southeastern area of the community and the “Residential Emphasis Mixed-Use” (REMU) zoning district designated across the remainder of the property. NWX is designed to meet the standards of these two underlying zoning designations. Commercial, office, mixed-use, and multi-family development within NWX is subject to all applicable design guidelines within the UDC. These supplemental Master Plan Design Guidelines articulate the unifying themes and additional standards that should be followed when considering the design of a new building and its relationship to the surrounding context. | Page5October 13, 2020 E. Phasing NWX will be built in multiple phases over several years. The Master Plan ensures that with each phase, the vehicular, bicycle and pedestrian pathways are constructed to facilitate seamless connections throughout the community and to the important natural and park areas which serve as focal features for recreation and social interactions. The Master Site Plan serves as the guiding document to assure that: • The phased development maintains enhanced multi-modal connectivity; • NWX remains pedestrian oriented; • NWX provides housing opportunities to meet a wide range of needs; and, each new phase will complement and enhance existing phases. An example tracking table for land use calculations of phased development of parcels is included in the appendix of this document. F. Administrative Organization The Master Developer, NWX, LLC, is responsible for creating, administering, and enforcing the design guidelines for NWX. This level of review will ensure that new construction projects, and any site modification exhibit design excellence and adherence to the design guidelines. The ARC may delegate and/or assign any of its powers and obligations as needed for the Architectural Review Committee (ARC). The ARC will review all development applications for adherence to the design guidelines, and then make approval/denial recommendations prior to an applicant submitting to the City. Final ARC approval/denial for all applications is communicated by the ARC and communicated in writing to the applicant. If the application is denied, the ARC will outline the reasons for denial. The applicant may then re-apply. The review process is conducted in addition to Federal, State, County, and City of Bozeman site or development review. Any application for new building or site development as well as modifications to any building or site, shall be reviewed by the ARC to determine compliance with the design guidelines. Review and compliance with applicable Federal, State and County requirements is the responsibility of the Owner. SECTION 2: SITE DESIGN GUIDELINE 2.1 SITE DESIGN OVERVIEW AND INTENT The NWX Master Site Plan serves as the vision for the community and the guide for development of each phase. This Master Site Plan establishes the areas designated for the commercial and residential uses, the primary road network, the location of primary parks, the interconnected trail system, and utilities. The physical design of all elements within NWX promote a vibrant, safe, and comfortable neighborhood with a clear identity and sense of place. | Page6October 13, 2020 The development guidelines expressed in this Master Site Plan are intended to uphold the community vision and promote consistency and quality throughout all aspects of the neighborhood design. The design elements create a baseline for design and are intended to be used as a framework from which designs may evolve to respond to changing market conditions and demand. The design guidelines are not intended to be rigid. Rather, they direct and guide development patterns and connections to provide a development framework to build upon. The architectural standards set forth herein, provide guidelines for creating aesthetically pleasing and unique neighborhoods that blend with the surrounding context. Landscape standards are set to preserve natural features, maintain a harmonious design with the built environment, and to establish a range of amenities for the residents of the community to enjoy. The purpose of these guidelines is to promote the following: A. NWX’s development guidelines are meant to enhance and protect the quality of development within NWX and add to the quality of life and community image already present within the City of Bozeman B. Protect and enhance the City’s long-term economic vitality though the build-out of NWX in accordance with these guidelines. C. Create walkable, well landscaped environments that encourage pedestrian movement between uses and gathering spaces. D. Promote and enhance multi-modal transportation and non-vehicular connections. E. Minimize adverse impacts of vehicular circulation throughout NWX and to existing development. F. Protect and enhance the security and health, safety and welfare of residents. G. Promote energy efficient and environmentally responsible development. 2.2 GENERAL SITE DESIGN GUIDELINES Site improvements shall meet the following objectives: A. Provide necessary emergency vehicle access and associated curb painting; B. Efficient and appropriately sized vehicle circulation and parking; C. Installation of safe, concise, and all-weather pedestrian pathways; D. The entire site is to be accessible and have pedestrian connections between all structures and the public way; E. Provide crime prevention through environmental design; F. Only underground utility services to be installed; G. Meters are to be placed on the least public side of each building or screened so they are not easily seen, as per the UDC requirements; H. Incorporate security site lighting with the least number of fixtures possible. 2.3 PERMITTED USES The NWX Framework Plan includes the location of the REMU and B2-M zoning designations established in NWX. It is intended that the permitted uses in the zoning districts be in accordance with the uses set forth under Table 38.310.040.A. | Page7October 13, 2020 2.4 STREETS, ACCESS, AND CIRCULATION The NWX Transportation Plan and Street Sections establishes the vehicular connections and design for each type of road. NWX is a well-connected neighborhood which provides vehicular, bicycle and pedestrian connections throughout and to the surrounding community. New development in NWX shall be designed in accordance with the intent of the Transportation Framework Plan. Flexibility in the location of these connections may be considered provided the intent of the primary north-south and east-west connections through the overall development is maintained. All public and private streets within NWX will comply with the City standards for arterial, collector streets, local streets, and City-standard alleys. To provide safe and efficient vehicular, bicycle, and pedestrian travel and to ensure a distinct and enhanced natural aesthetic along each street in NWX, this plan includes street sections for the various streets within the community which should be constructed with future development. Road construction will be phased with build-out of each proposed new neighborhood and in accordance with the NWX phasing plan. It is intended that the transportation network within NWX meet the following objectives: A. Include a street and sidewalk pattern, orientation, and hierarchy that promotes walkability between and through each neighborhood. B. Design and construct streets that support a multi-modal environment, including vehicular, pedestrian, and bicycle traffic. C. Create a streetscape that provides continuity throughout the development D. Maintain pedestrian safety at all intersections by installing enhanced paving or other alternative methods of increasing the visibility of pedestrians where feasible. E. Minimize the use of curb cuts along pedestrian centric streets to minimize conflicts between pedestrians and vehicles. 2.5 PEDESTRIAN AND BICYCLE CONNECTIVITY A major component of NWX is pedestrian connectivity, both internal to the site, as well as externally to existing adjacent neighborhoods. Special emphasis placed on quality and functionality of the pedestrian environment improves social interaction, connects the existing fabric of the adjacent neighborhood and encourages travel from destination to destination within the larger community without the use of a motor vehicle. Similarly, bicycle connectivity is integrated throughout NWX, including the connection of the regional trail through the site. It is intended that the pedestrian and bicycle connections meet the following objectives: A. Create a vibrant streetscape that enhances the pedestrian and cyclists experience while providing a sense of safety. B. Provide clear paths of travel for bicyclists, pedestrians, and vehicles with designated areas to minimize conflicts, where feasible. C. Provide direct routes to the internal parks and open spaces, Homestead Park, neighborhoods, the commercial areas, and to the surrounding community. D. In the commercial areas, create an inviting environment that has clear circulation paths from parking areas to building entries. | Page8October 13, 2020 2.6 PARKS Key focal points planned for NWX are parks, both smaller pocket parks and neighborhood parks. The natural amenities found along the newly established Homestead Park (as identified on the Master Site Plan as Parks 1, 2, and 3) will create opportunities for community recreation and social interaction. The Residential areas and streets are designed around the natural areas to create active and passive park areas and well-connected pedestrian connections throughout the community. Parks to be located within NWX are planned to form a unifying system including a range of improved parks to natural open spaces. This system is intended to link each park and join the various areas of the proposed new neighborhood together. Each park is planned to have its own identifiable theme creating a unique identity for each surrounding part of the neighborhood. The parks will be designed to provide: A. A range of both active and passive activities to encourage utilization. B. Year-round amenities for a full range of age-group users C. Promote a healthy lifestyle based on immediate access to limitless recreational opportunities. Due to the overall vision of the NWX park system and the location of Homestead Park, not all parks will have the frontage requirements set forth under the UDC. Rather, all parks will be accessible by the residents as well as the surrounding community and are intended to be primarily accessed by walking and biking. Based on the planned gridded and connected local street network, an extensive amount of conveniently located on-street parking is available for park visitors throughout NWX for those that do drive. Bozeman Sports Park and the Gallatin County Regional Park, located just to the east of NWX, are significant community assets providing ample opportunities for programmed and unprogrammed recreational and sporting activities, playgrounds, aquatic resources, dog parks, trails and picnic areas. Considering the variety of programming needs that are met at the Bozeman Sports and Gallatin Regional Parks, the NWX park system offers amenities that complement the existing neighborhood parks by being more nature-based along Homestead Park and community focused for the other internal parks. This added collection of parks at NWX extends the range of parks and recreation options for City residents in the general area of NWX. Homestead Park will be the heart of the newly planned NWX community with its well-established connected network of park areas and natural amenities. The Homestead Park will be constructed on both sides of Baxter Ditch. The ditch and its associated wetlands will be significantly enhanced with improvements to the overall natural habitat through the planting of native plants. The wetlands and zone 1 wetland setbacks serve as the natural amenities to this integrated park system, while active and passive recreation is intended within the zone 2 wetland setback areas and the upland areas, including an integrated network of trails. Examples of opportunities for the programming of each park area are shown on the “Homestead Park Concept Plan”. Homestead Park is intended to provide the following: A. A series of interconnected parks with various types of active and passive programming B. A well-connected pedestrian path system throughout the park; C. Enhanced wetland and wetland setback areas to improve the natural habitats biological functions of this watercourse; D. Enhanced bridge crossings; and E. Landscaping with native plants in a manner that enhances the natural areas and lends to the overall aesthetic experience of this park system. | Page9October 13, 2020 Development of the parks will be phased over time in association with construction of future subdivisions. Over 14 acres of park land is envisioned for Homestead Park within NWX. With the build out of each new subdivision phase, park land dedication requirements will be met in accordance with the UDC by the following: A. Construction of a new park (or an adequately sized portion of a new park) B. Improvements to a new park or an existing park C. Payment of cash in-lieu contributions to the park “bank” established with the development of Homestead Park. Improvements-in-lieu are encouraged to establish parks within the NWX development. D. Any combination of these mechanisms subsequent to approvals by the NWX ARC (NWX, LLC or assigns) and the City of Bozeman. Lots that front public parks or trails shall comply with setbacks, buffering, landscape and otehr requirements per the UDC. An example tracking table for park dedication and tracking of phased parcels is included in the appendix of this document. 2.7 SITE LANDSCAPE A. General Requirements The proposed landscape concept for NWX responds appropriately to the various aesthetic, functional and environmental factors of the site. Key natural amenities existing on the site will generally be preserved and enhanced, including Baxter Ditch and Baxter Creek and other established, protected wetlands. Implementing a plant palette that is appropriate for the region which creates habitat for local flora and fauna to thrive, is planned to be implemented at NWX. The proposed landscape character will be an integration of some formalized use areas along with native, free-flowing landscape blending existing elements with new improvements. A series of interconnected parks will be located throughout the proposed neighborhood, incorporating key opportunities for natural/naturalized features and sustaining NWX as a beautiful and vibrant new neighborhood in Bozeman. B. Landscape Areas The Landscape Framework Plan categorizes common areas within NWX into several distinct categories based on location and proposed neighborhood improvements. The categories are listed below with the objective of providing an overall neighborhood design understanding to implement and reinforce the landscape design concept within the site. An overall landscape palette will be established for NWX in order to compliment the architecture and promote a certain level of overall consistency and character throughout the community. | Page10October 13, 2020 Perimeter Landscape Areas Perimeter landscape areas are generally defined as the perimeter right-of-way areas for the proposed new neighborhood, and also incorporates any community open spaces located between the right-of-way boundaries and adjacent private property lines. The perimeter landscape treatment will generally consist of free-flowing plant masses to integrate the various neighborhood phases, through its build-out, while creating a uniform, consistent character amongst the various types of architectural styles. Plant masses consisting of evergreens, ornamental grasses, and native plant material will provide screening (where needed), establish key view corridors into the neighborhood and create year-round visual interest with a variety of color and texture. The landscape character will include both bold patterning and free flowing landscape, consistent with the intended function and character of each area within the neighborhood. Common Areas Generally defined as the area between the road right-of-way and the adjacent property line, common areas shall act as a transitional zone incorporating plant materials found in both the adjacent streetscape materials palette and private lots/uses materials palette within the neighborhood. An automatic irrigation system is to be implemented in the common area zone as part of the builder‘s installed landscape development of each respective lot/use. These areas should be planted with sod or other appropriate landscape material, per the approved landscape plant list for Northwest Crossing. Careful consideration should be given to the adjacent landscape context during the design and development of the common areas and adjacent lots/uses. Streetscape Areas This zone is located immediately adjacent to roadways or streets within the right-of-way, consisting of an improved landscape corridor of varying width, and generally transitioning into the adjacent common area zones. Local street tree lawns will incorporate a minimum quantity of trees that can be spaced in regimented clustered patterns with irrigated turf (or other appropriate ground cover). A minimum of one (1) street tree will be required for lots less than 50’ in width, however, adjustment in spacing of street trees may be required to ensure spacing is appropriate for all factors involved in engineering and design of these spaces, including driveways. It will be the responsibility of the builders to implement required improvements within said streetscape including, sidewalks, landscape, irrigation, and trees located adjacent to their respective lots/uses. Maintenance of said area will be the responsibility of the builder / homeowner. The intent within the streetscape areas is to create a uniform streetscape hierarchy throughout the neighborhood by generally uniformly spacing trees within the tree lawn and utilizing a consistent palette of plant materials. | Page11October 13, 2020 Community Entrances Community entry landscape zones are located at the street intersections along the neighborhood perimeter in the area of the edge of the street rights-of-way or adjacent property lines. Community entries may transition into common areas or may abut private properties/uses. Community entries may incorporate sidewalks, trails, community signage, monumentation and other elements. Neighborhood markers may also be provided to designate neighborhood areas and aid in way- finding and identity. C. Site Furnishings and Hardscape Site furnishings and hardscape can be used to enhance the experience of individual spaces and overall function of the landscape. Hardscape consisting of trails, walks, and plazas provide opportunities for annual recreational use. Site furnishings, including benches, tables, bike racks, trash receptacles, seat walls, and other elements, shall enhance the neighborhood’s theme by utilizing forms and materials consistent with the architecture style and landscape character. All furnishings should be part of a uniform stylistic “family” providing aesthetic accents and promoting use for the public. D. Commercial, Office, Mixed-Use, and Multi-Family Landscaping Landscape and open space throughout the commercial hub should be designed to strengthen the pedestrian experience. The design of the streetscape and common areas should be done in a way that integrates the commercial corner into the fabric of the overall community. Streetscape Design The commercial streetscape design will be critical in providing a cohesive experience for visitors and residents of NWX. This zone is located immediately adjacent to roadways or streets within the right- of-way and should consist of an improved landscape corridor of varying width. The streetscape will include frontage along all major arterial streets, collector roads, and internal streets. The following are general streetscape design requirements: A. Clear pedestrian paths shall be integrated into the streetscape in order to create a continuous and accessible walkway. B. Sod shall be allowed in tree lawns at a minimum of 5’ in width for maintenance purposes. Enhanced tree lawns with a mix of shrub, grass, and perennial plantings can be used in place of traditional sod where applicable and should meet all city standard vision triangle requirements. Drip irrigation shall be required for the longevity of the plant material located within planting beds. Maintenance of said area will be the responsibility of the builder / business owner. | Page12October 13, 2020 C. Areas that require increased pedestrian space to promote the urban character shall utilize tree grates, vaults, and planters in place of traditional tree lawns. Tree grates shall be made of durable materials and shall be consistent with the overall theme of the community. See example tree grate in the commercial MSP drawings. Planters shall be used to soften the façade of buildings, define transition spaces between public to private or vehicular to pedestrian, create diversity and break up the expanse of the streetscape, and create spaces for conversation and gathering. D. Diversity of plant species is highly recommended with trees and shrubs. No more than 3 trees of the same species should be used in a continuous span within the right of way landscape areas. Refer to sheets MSP1.21 for a list of recommended street trees. Common Area Landscaping Common areas can be characterized by public spaces outside of the right-of-way and should be designed with the intent of creating social gathering spaces. Landscaping shall be in harmony with the common theme and character of the nearby streetscape and shall meet or exceed minimum City standards. The following are general requirements for common area landscaping: A. Offer a range of amenities, both active and passive, for the community to gather and relax B. Benches, café tables with umbrellas, or other forms of seating options, should be located in areas of high pedestrian activity in order to activate the space and offer areas of relaxation for the residents C. Bike racks and trash receptacles shall be focused in key pedestrian spaces, such as plazas, building entrances, or other areas of intensive use. D. Movable planters consisting of grasses, shrubs, seasonal annuals, and perennials should be used in key areas, such as plazas to define seating areas, or entrances to buildings where plantings are minimized. When used along sidewalks, a minimum clearance of 5’ shall be maintained free and clear for pedestrian circulation. E. Plant material should utilize smart water consumption practices and should be hardy in nature. F. Diversity of plant species is highly recommended with trees and shrubs. A variety of deciduous and/or evergreen trees should be used to create a bio-diverse community which provides visual interest all year long. Refer to sheet MSP1. 18 and MSP1.19 for a list of recommended plants. Site Furnishings and Hardscape Site furnishings and hardscape can be used to enhance the experience of individual spaces and overall function of the landscape. Site furnishings, including benches, tables, bike racks, trash receptacles, seat walls, and other elements, shall enhance the commercial neighborhood’s theme by utilizing forms and materials consistent with the architecture style and landscape character. This can be done by addressing the following requirements: A. All furnishings should be part of a uniform stylistic “family” providing aesthetic accents to the architecture, which will exhibit a modern interpretation on historic agriculture and light industrial architecture. B. Landscape furniture should be made of weather resistant materials that are durable and easy to maintain, such as powder coated steel or composites. | Page13October 13, 2020 C. Pedestrian and street lighting fixtures shall be incorporated to enhance the pedestrian experience and create a safe and welcoming environment. LED lighting with a fixture and pole that matches the development standard is required to be used through the commercial development. See AC5.1 for details. Also, refer to Lighting Standards set forth herein for additional standards. D. Walks and plazas in key pedestrian areas shall utilize a variety of decorative paving in order to break up large expanses of hardscape. Decorative paving shall be defined as areas of pavement that provide contrast and visible variation. This can be done through a variety of treatments, such as: exposed material, brush/texture, colored concrete, pavers, stone, tile, or enhanced scoring patterns. E. All pedestrian crosswalks are to be of matching color and texture across the commercial development. 2.8 SITE LIGHTING Lighting is important to the character and use of the individual sites within NWX. Lighting will be used to encourage activity after dark, providing a sense of security and safety, articulating project identification at entries, and creating overall visual interest and appeal. Specific lighting standards are not intended to be replicated across the entire community but are in place to provide a sense of continuity in lighting style. Variations in identity between different land users and uses will be allowed but the overriding style must be maintained. Lighting throughout NWX shall be functional and serve the purpose of enhancing safety for pedestrians, bicyclists, and vehicular traffic. All lighting must be dark sky compliant and meet the requirements of the City of Bozeman for dark sky compliant lighting. Street lighting in residential areas shall follow the minimum standards set by the current City of Bozeman Lighting Code. Light fixtures installed in City right-of-way will be part of a City of Bozeman Street Lighting District and must meet current City standards. Lighting forms and materials within public places such as parks, parking areas, mixed use areas and gathering places shall be generally compatible with the architectural styles of adjacent buildings or structures. Exterior building lighting, either attached to, or part of, the building will be the minimum needed to provide for general illumination, security, and safety at entries, patios, outdoor spaces, and associated landscape structures. Site lighting should follow the following additional principles: A. Building lighting shall be compatible with the overall building style and form and shall also reflect the lighting themes present on surrounding existing structures in order to ensure an overall coordinated lighting theme. B. Lighting shall use corrected color temperature (CCT) of no more than three thousand (3,000) degrees Kelvin. C. High pressure sodium fixtures are not permitted. D. Light poles and fixtures should be architecturally compatible with building design and adjacent properties. E. Parking and pedestrian lights should be of similar character. F. All parking lot lights shall be of consistent design/type. | Page14October 13, 2020 G. Formed concrete bases shall have architectural design and interest. No sonotube formed concrete bases with “coil” pattern shall be permitted. H. All parking lot light poles shall be located within parking islands, medians or perimeter landscape beds of lots. I. Additional methods of lighting shall include bollards with integrated lights and recessed lighting in walls or stair treads and handrail lights. J. Special lighting that accents building features and creates visual interest is permitted in commercial developments, provided that the design continuity is maintained among buildings. K. Landscape lighting should enhance and complement, not overpower, the landscape. 2.9 NEIGHBORHOOD CENTERS The NWX “Neighborhood Center” is strategically created through the creation of NWX Neighborhood Commercial Center located within Parcels A and B. The NWX neighborhood commercial center is intended to serve the needs of the surrounding existing and future neighborhoods and Gallatin High School but will also draw from more than the immediate vicinity and serve the broader geographical area, especially due to its location adjacent to from Cottonwood Road and West Oak Street. The commercial center will support and give identity to the neighborhood by providing a visible and distinctive focal point and is intended to have commercial uses such as daycares, smaller scale groceries, bakeries, coffee shops, retail stores, small restaurants, offices, and other services to meet the needs of the community. Civic uses may also be located here. Plazas and courtyards integral to the building placement, promote the vitality of this center by fostering social interactions through the myriad of programming opportunities envisioned for this area. The overall design of this area will create a high-quality, vibrant center through strategic site layout of buildings which are placed to take full advantage of the expansive mountain views, along with integrated and cohesive pedestrian connections and enhanced landscape treatments, both internal to the site and at the perimeter. Architecture will have unifying themes and elements, as set forth in the Building Design Guidelines, to create a cohesive character throughout this center. Certain elements, such as architectural materials, pavers, lighting, benches, waste receptacles, and other pedestrian amenities will be used consistently throughout this area in order to create the overall context of this center. These amenities should be consistent in design character or compatible throughout the center. The Commercial Center will be maintained by a property owner’s association and is subject to the community design framework master plan provisions of sections 38.210.130 and 38.510.030. | Page15October 13, 2020 2.10 SITE DRAINAGE The NWX Preliminary Storm Drainage Plan displays potential areas that can be used for storm water runoff storage. The areas shown are just a general illustration of the anticipated area needed for storm water runoff storage. The actual locations are likely to change during either site plan or subdivision review. Storm drainage within the commercial areas located in the B2-M Zoning District will be contained within the boundaries of each parcel or through a shared subgrade detention system. 2.11 WATER AND SEWER UTILITIES The Water and Sewer Preliminary Plans display the preliminary water main and sewer main layout in the local roads and surrounding arterial streets. 2.12 SURFACE WATER AND WETLANDS The NWX Surface Water and Wetlands exhibit displays Baxter Creek and Baxter Ditch as they run through the property. It also shows the extents of the delineated wetlands and corresponding 50’ wetland setback. Groundwater monitoring well locations are also displayed on this exhibit. 2.13 PARKING Parking standards shall meet the requirements set forth in the UDC, unless it is demonstrated that alternatives result in better design, efficiency and overall functionality for the site. In designing parking areas, the following should be considered: A. Parking lots should be located such that it will be subordinate to other site amenities. B. On-site parking should be located inside or behind a building, where visual impacts will be minimized. Pavers, “grasscrete”, and bioswales are encouraged to minimize the expansive use of asphalt. C. Parking lots shall be landscaped in accordance with the UDC requirements and NWX Landscape Design Guidelines. 2.14 SIGNAGE Signage within the commercial area should be innovative in order to establish the unique brand and image of the business but should also reflect those architectural characteristics which make NWX unique. Unless otherwise approved, all site signs and sign lighting must comply with City of Bozeman Unified Development Code requirements and with the NWX Comprehensive Sign Plan. A sign permit must be obtained by the City of Bozeman. The following general principals should be considered in sign design: A. Signage should have simple, modern, and efficient style that connects to the Project’s agrarian theme and the material palette, with some flexibility allowed to accommodate users, whether more creative or more programmed. B. Signage should be designed to minimize clutter, with an emphasis on managing locations to minimize conflicts, blockages and obstructions of both circulation patterns and view corridors. 2.15 SNOW STORAGE This NWX Master Plan acknowledges that a comprehensive snow removal plan is necessary in Bozeman | Page16October 13, 2020 due to the presence of significant seasonal snow fall. All Site Plans and Preliminary Plats are required to provide a Snow Storage and Removal Plan for the removal of snow from drives, walkways, roofs, and parking areas. The plans will identify measures to minimize snow and ice build-up on driveways, parking areas, and pedestrian walkways and also provide adequate space for snow storage in designated areas. Snow storage easements will be designated on the final plat. The property owner shall be responsible for all on-site snow removal and storage on privately owned residential properties, including public walks fronting those properties within street rights-of-way. Within the commercial center and the multi-family neighborhood, the property management company shall be responsible for snow removal on all common spaces including but not limited to parking lots, sidewalks, courtyards and any other public spaces. Snow removal plans for these areas shall also identify adequate location for snow storage. Within the residential areas, the Homeowner’s Association (HOA) will be responsible for snow removal and storage in open spaces, parks, alleys, and public walks fronting those properties within street rights- of-way. The City of Bozeman will be responsible for snow removal and storage on public streets. 2.16 WIRELESS AND FIBER Wireless & Fiber services are being considered to be incorporated throughout the development. With each phase, infrastructure will be considered to be implemented. SECTION 3: BUILDING DESIGN 3.1 OVERALL DESIGN CHARACTER The design character is a key element in establishing the desired identity for NWX. The following images depict the general character intended for the proposed new neighborhood in Bozeman. The full combination of the character exhibited in the collection of images should be considered holistically, rather than selecting any single image or detail within an image. The graphics included are for reference only. The resulting character defining elements, including architecture for commercial, office, mixed- use, and multi-family development within NWX, landscape improvements, streetscape elements, way- finding/signage elements, and other site improvements will be designed and constructed in phases with future land use applications and in accordance with the NWX Master Site Plan. | Page17October 13, 2020 3.2 ARCHITECTURAL THEME Commercial, office, mixed-use, and multi-family development within NWX will exhibit a modern interpretation of historic agriculture and light industrial architecture both as outlined below. The architecture will express its design through materials selected, transparency proportion, and building articulation. The architecture should be grounded in its site, both from a local and regional perspective. The architecture should be a modern expression of Montana and Rocky Mountain Architectural Styles manifested thought the use of quality materials and façade articulation. Architectural queues to be considered to achieve this image should be derived from modern interpretations of these authentic styles: rustic, ranch, agrarian, folk, prairie, and mountain western and historic light industrial. These primary architectural features should exhibit the following characteristics: • Significant transparency, especially on the first floor. Multi-family development is exempt from this requirement unless retail or office uses are intended for the first floor; • Significant overhangs on portions of the buildings and especially at corners or primary entrances where feasible; • A mix of materials including but not limited to wood or synthetic wood products, stone, brick, architectural grade metal; Design considerations shall include creating visual interest using a variety of building types within each development area while maintaining a sense of compatibility with the surrounding buildings. New development should be consistent and complimentary to existing NWX architecture and reflected on all sides of the buildings. Buildings shall be designed to have a strong connection to the surrounding natural and built environment. The use of energy-efficient design and materials are encouraged. | Page18October 13, 2020 3.3 RELATION TO STREET In the Commercial Center, it is important that buildings are placed along the street frontage in order to activate public spaces and connect multi-modal users to the buildings. Buildings will meet the block frontage of the underlying zoning district and for the respective use. However, alternative design considerations may be considered and supported, such as placing buildings to front a public plaza or park, provided the overall intent of the design guidelines is met and such alternatives are approved through the applicable City process. Streets should be active by gathering areas and other pedestrian amenities that are usable by the public. These spaces should be part of a walkable and well-landscaped environment that encourages multi-modal movement. The design and details of streets, frontages, and buildings should support this objective. Principles: A. Buildings shall be sited to provide for a pedestrian scale relation to the street which they front. B. Buildings shall be designed to provide visual interest on all facades which will be seen from streets, alleys, and pedestrian ways. C. Buildings should express a human scale through materials and forms that are reflective of the style theme as articulated herein. D. Large store-front display windows are encouraged. Buildings should be oriented to promote views through and into each commercial use. E. Streets, sidewalks and pathways should encourage pedestrian activity and use. F. Multi-unit residential buildings should include entrances that are welcoming, organized and safe for residents and visitors from the street. These frontages may include courtyards or gateways and should encourage social interaction. G. Utilize design principles of crime prevention through environmental design. 3.4 EXTERIOR TREATMENT All building facades visible from a public street or public space should provide a level of finished architectural quality and be designed to the human scale. Buildings should incorporate variations in height, reveals, materials, colors, and other architectural treatments to create interest in the individual building and all of the buildings collectively. Buildings identified as high visibility street corners as defined in the UDC shall incorporate building details that comply with UDC requirements and recommendations. In the design of the exterior treatment of buildings, the following should be considered: A. Buildings designs are encouraged to utilize simple forms with clean lines and layered materials. B. Neutral color schemes are encouraged with “pops” of color added for visual interest. Bright colors should only be used as a subordinate color unless otherwise approved by the applicable review process. | Page19October 13, 2020 C. Large areas of undifferentiated or blank building facades should be avoided. D. Where buildings have base, middle, and top, floor lines in buildings should be articulated to differentiate each layer. E. Scaling elements and details should be integral with the building form and construction, not a thinly applied facade. F. Variation in building scaling and detail should relate to the scale and function of pedestrian-active uses along the facade, creating human-scale design to support entrances, plazas, patios and amenity areas. G. Both horizontal and vertical architectural scaling patterns should be used. H. For facades longer than 200 feet, at least one major identifying feature shall be incorporated into the building design. This feature shall be one of the following or a similar feature that creates visual interest: cupola, rotunda, spire, dome or clock. I. Base elements shall not exceed two stories in height unless overall height of the building form and massing dictate a taller base. J. Base elements shall be detailed to enhance the architectural character of the streetscape and provide pedestrian friendly scale. K. Provide appropriate building accent lighting above street level to highlight architectural elements. L. Architectural details shall occur on all four sides of the building to reduce the back of house 3.5 ROOF FORMS AND BUILDING HEIGHT Unless otherwise approved by the City of Bozeman, the maximum height of buildings will not exceed the height established in the UDC for the underlying zoning district. The following principals related to building height should be incorporated into the design of the buildings: A. A range of buildings heights are encouraged. B. A mix of flat and sloped rooflines are encouraged and may be used on the same building or may be incorporated into various buildings in the same area. C. The height of buildings should add variety and visual interest as well as break down the building massing. D. Roof forms longer than 100’ shall be broken with a vertical change of not less than 2’ in height. E. Building parapet heights shall be varied and provide vertical relief to the parapet line. Parapet changes should be proportionate to the building element that it reflects; at a minimum there must be at least of (1) foot in height in difference from the adjacent parapet. F. Roof forms and parapet heights should be varied, and where appropriate, should emphasize the facade articulation and variation of building materials. Roof forms over 50 linear feet shall incorporate at least two of the following: | Page20October 13, 2020 a. Changes in roof or parapet height b. Decorative cornice or eave treatment c. Differentiation in material and/or color d. Changes in roof type, such as hipped or gabled rooflines and modulated flat roof lines. 3.6 BUILDING FORM AND SCALE Building form and scale are important contributors to how an individual interprets his or her experience of a place. Buildings should exhibit the desired neighborhood character with the appropriate mass and scale of buildings. Variations in building massing are encouraged to create architectural and aesthetic interest. The following principals related to building form and scale should be followed when considering the design of a building: A. The size, scale, and form of buildings and their placement on a parcel should be compatible with adjacent and nearby properties and with the dominate neighborhood development pattern. B. For commercial buildings, it is encouraged that 360-degree design be articulated to the maximum extent practicable. C. The roof height, façade plane, setbacks, and floor-to-floor height should be varied and appropriate to the surrounding buildings. D. Buildings should include characteristic features so each building contributes to a cohesive planned area, without a monotonous design. E. Where appropriate to the architectural style, overhanging eaves should include visual support of the eaves. F. Facades should transition in scale and level of articulation, so they respond to pedestrian interaction. 3.7 MATERIALS To reflect the architectural characteristics envisioned for NWX and as established in Sections 2.1 and 2.2 of these Design Guidelines buildings should be designed using highly durable, weather resistant, low maintenance materials and meet the following principals to the greatest extent practicable: A. Use materials that convey a sense of quality, permanence and attention to detail, creating a rich variety of materials, colors and textures. B. Use a mix of materials that are harmonious and compliment each other and those found on surrounding buildings to create a layered, textured, and integrated aesthetic. C. Materials such as naturally appearing wood-alternatives, reclaimed wood, timber, steel, brick and concrete are encouraged and should be layered to provide for aesthetic interest and cohesiveness throughout the neighborhood. D. The use of metal, including weathering steel, corrugated panels, standing seam metal panels, and copper, may be used as a subordinate material. Galvanized metal is prohibited. E. Use materials that support a more sustainable environment. Using locally sourced materials offers additional layers of benefit in the form of stimulating the local economy, reducing the energy involved in transportation, and being a product of the area. F. Exterior cladding and detailing should be chosen for its ability to work with the local climate and resist degradation. G. Choose environmentally and historically appropriate materials that are durable, resilient, easily | Page21October 13, 2020 sourced and repaired, resist aging poorly, and are natural and sustainable. H. Use materials that create continuity between buildings and Districts. I. Installation methods should be carefully detailed to provide clean transitions at corners, between panels, material changes, openings and the general exposed fastener pattern. J. When seen from a distance, materials should emphasize the form of the structure. When viewed at a closer range, materials should have a rich textural quality. K. Building color schemes should tie building elements together, relate separate buildings to each other, and should be used to enhance the architectural form and character of the buildings. L. The use of similar materials on the same building or nearby buildings do not need to match the same color but should complement the existing color palette. 3.8 TRANSPARENCY Building transparency contributes significantly to the pedestrian experience in commercial areas. Glazing on the ground floor increases the visibility of goods for sale and active uses such as restaurants and cafés. When in concert with the overall aesthetics of a building and surrounding buildings, transparency creates a pedestrian-friendly environment and encourages visitors to walk between multiple destinations within the area. The following principals related to building transparency should be followed when considering the design of a building: A. Expansive windows on both commercial and residential buildings are encouraged to maximize solar exposure and provide connectivity from interior to exterior. B. A variety of glass types may be used at or above the ground floor, such as translucent glass, etched glass, glass block, acrylic channel glass, as long as the minimum transparency standards are met. C. Retail or restaurant uses: Where a retail or restaurant use occupies the ground floor, the facade facing the primary street should be at least 60% transparent in addition to meeting Block Frontage Standards required per the UDC. All other facades facing a street or public space should be at least 30% transparent. D. All other residential uses (excluding retail/restaurant): The facade facing the primary street should be at least 40% transparent in addition to meeting Block Frontage Standards required per the UDC. All other facades facing a street or public space should be at least 25% transparent. E. Residential uses: Where a residential use occupies the ground floor, windows should be provided where appropriate to create visual interest, while also balancing the need for residents’ privacy in addition to meeting Block Frontage Standards required per the UDC. | Page22October 13, 2020 3.9 ENTRANCES Building entrances should be unique to each building, but the design should draw from the architectural themes established in these Design Guidelines and the surrounding context. Visually interesting building entrances will draw people from one business to another which contributes to a lively pedestrian experience. The following principals related to building entrances should be followed when considering the design of a building: A. Visually emphasize the major entry or entries to a building or ground floor use. B. Provide convenient access to buildings from streets, drives, and pedestrian corridors. C. Buildings should provide at least one primary building entry oriented to or visible from a public right-of-way. D. Street oriented building entries should be directly connected to the public sidewalk. E. Where parking is located internal to the site, multiple building entries are encouraged to allow direct access to the buildings. F. Weather protection shall be provided at all primary building entrances via Flat canopies or awnings which are complimentary to the building should be located at the approach to and over entries. Recessed entrances are also encouraged as another means to protecting pedestrians from weather. 3.10 MECHANICAL EQUIPMENT AND UTILITIES To maintain visual aesthetics throughout the site, it is important to screen mechanical equipment and utilities. The following guidelines apply to the screening of mechanical equipment and utilities: A. All mechanical equipment and utilities visible from public ways must be screened. B. If feasible, building service areas and mechanical equipment should be integrated into the overall building design such that it is not visible from a public way. C. Screening should use elements, materials, and forms compatible with the building design and shall be compliant with all guidelines pertaining to building design described herein. D. Consider views from neighboring buildings in the design and enclosure of rooftop equipment. E. Screening shall be as required by the City of Bozeman’s Unified Development Code. 3.11 TRASH AND STORAGE In the Neighborhood Center, the visual impacts of trash and storage areas shall be minimized. Principles: A. Trash enclosures shall be constructed with similar materials as those of the primary structure. B. Trash enclosures should provide adequate room for trash, recycling and composting. C. Trash enclosures, including large waste containers (dumpsters) should be screened from view of major pedestrian routes as outlined in the UDC. D. Combine trash and storage areas where feasible. | Page23October 13, 2020 APPENDIX: EXAMPLE TRACKING TABLES A.1 MASTER LEVEL RESIDENTIAL, COMMERCIAL & PARK LAND DEDICATION TABLE | Page24October 13, 2020 A.2 PARCEL TRACKING TABLE | Page25October 13, 2020 A.3 PARKLAND REQUIREMENTS AND DEDICATION See NWX Master Site Plan sheet MSP 1.04 for information on required park dedication.
