The project is located on the currently vacant 8.78-acre lot between West Babcock and Fallon Streets just to the west of North Cottonwood Road. The land is zoned as R-O within the City of Bozeman and is zoned as R-4 to the immediate west and B-2 to the immediate east. The site is adjacent to apartment buildings to the west and Baxter Creek to the east. The site features Baxter Creek and wetland areas as a major site feature for its natural view shed and as a focus. There are exceptional views of the Bridger Mountains to the east of the site. As proposed the project would include (6) 12-plex apartment buildings and (4) 18-plex apartment buildings to introduce a total of 138 new 2-bedroom apartments units to west Bozeman. The proposed project would be built in three separate phases to occur in 1-year intervals. The development is intended create quality and efficient living space that provides security, privacy, quality living space, and usable shared community space. Intent of Design Guidelines: The intent of these design guidelines is to guide future phases of planning, design, and construction within the West Side Flats Development. These design guidelines do not take precedence over the Bozeman Uniform Development Code “UDO” or Governing Building Codes. These guidelines are to guide the major design decisions and intent withing the West Side Flats development. 4 | P a g e Design Intent: It is our intention to create a quality, attractive, and efficient apartment project that lasts the test of time for aesthetics and functionality. The open-air three-story apartment buildings are designed for maximum privacy, safety, views, ease of construction and quality living space. We designed the buildings to include both private outdoor space and communal outdoor spaces. It is our intent to provide a safe friendly feeling environment for the tenants. The site design is intended to minimize the impact of vehicular traffic on the apartments. The site design encourages interaction with nature, walking, biking, and outdoor activities in general. 5 | P a g e Privacy: The West Side Flats building, and site design offers maximum privacy for each apartment. Using landscaping and minimum 10’ setbacks between all parking and public areas, the units will offer a sense of privacy. In addition to the setbacks the units are designed to separate the living areas of the units from the parking lots. The unit design places the kitchens, living areas, and private outdoor areas away from the parking lot, thus creating private feeling usable areas toward the private viewsheds and open outdoor space. Safety: The design of the buildings and site layout are intended to offer a safe feeling environment for the user. To help us achieve the safe user experience the building design have no enclosed common areas. This design configuration discourages blind corners and long dark corridors common to most apartment building designs. The open outdoor common space is meant to feel secure while not feeling enclosed by providing open site lines and being outdoor rather than in a hallway or corridor. The ample night skies compliant building lighting throughout the project will also lend to the safety of the development. Common areas around the buildings are designed to have good lighting levels. Views: The site location allows for viewsheds of the Bridger mountains and open views to both the north and south. The layout of the buildings provide private portions of the apartments facing inward toward the parking lots. The living, kitchen and patios face external to the lot taking advantage of the open views away from the site. This building orientation also presents the most interesting side of the building to the surrounding neighborhood while screening the “internal” parking and driving areas. The vertical orientation of the flat type apartments take advantage of the two and three-story building heights providing excellent views from the apartments. Economy: Due to the high cost of land and construction, the project is designed for efficiency in both the 6 | P a g e use of land and economy of construction. The three-story design allows for a higher unit density and the stacking layout of the floors allows for simplified efficient construction. Nature: West Side Flats is located adjacent to Baxter Creek and is intended to take advantage of this natural feature. The site is laid out with the majority of buildings placed to the edge of Baxter Creek waterway. Six of the nine building designed for the project face the Baxter Creek. This will provide exceptional natural views of the watercourse and Bridger Mountains to 90 residences. In addition to the exceptional views offed on site, the project is designed to interact with Baxter Creek using open space and nature trails along the edges of Baxter Creek. The project offers a road mix “nature” trail running the entire north to south length of the development. This will provide direct access to surrounding neighbors and West Side Flats to a quality walking nature path. The natural walking trail along Baxter Creek also ties two east west trails allowing the apartment buildings to the west direct access to onsite trails, as well as providing access through the site to all trail users. In addition to the pedestrian friendly trail system, the project is proposing a common outdoor exercise area for use by the public and tenants. The equipment includes a built-in fitness rack for pullups and built in dip station bench. Site Design: Permitted Uses: West Side Flats is zoning as R-O per the Bozeman UDC. R-O is defined in the UDC as follows: The intent of the R-O residential-office district is to provide for and encourage the development of multi-household and apartment development and compatible professional offices and businesses that would blend well with adjacent land uses. As planned, West Side Flats will be exclusively apartment use. Related commercial and noncommercial amenities that serve and compliment the residential community will be encouraged. All uses defined in the Bozeman UDO under R-O zoning will be allowed. West Side Flats Setbacks: Building SetbacksFront setback 15’ Rear setback 20’ Side setback 5’Watercourse setback zone 1 30’Watercourse setback zone 2 50’ 7 | P a g e All setbacks as defined in the Bozeman UDO under R-O zoning will be allowed. Landscape Design: Landscaping plays an important role in the overall success of West Side Flats. Thoughtful landscape design is intended to enhance the buildings by easing the transition of building to site. All buildings will have transitional plantings between the building edge and site. The perimeter building landscaping will also provide privacy for the first story living units, specifically the bedroom units. The landscape design also will provide screening from vehicular traffic for the first story living units. The landscape design is also configured so parking areas are well screened from areas surrounding West Side Flats. Landscaping has been added to the open space areas and Baxter Creek to further enhance the sites natural common open space and trail system. All sodded areas will contain underground irrigation sprinklers. All landscaped beds will receive drip irrigation. All landscape edging will be metal edging. Seventy five percent of all trees and plantings will be drought tolerant species to conserve water consumption. All future development within West Side Flats will be required to utilize a Landscape Professional or Landscape Architect. All proposed and future landscape design must meet Bozeman UDO minimums. Snow Storage & Snow Removal: Snow Storage will be critical during the winter season in West Side Flats. All future development and site plans must indicate adequate and functional snow storage areas. During the 8 | P a g e initial two phases of the development snow storage can be placed at the edge of the non- developed parking and driveways. All areas requiring snow removal in the West Side Flats will be the responsibility of the management company responsible for property management and maintenance. Pedestrian Trails and Site Connectivity: The West Side Flats Project provides numerous pedestrian trails and sidewalks to enhance the day to day living experience within the development. The trails and sidewalks are intended to promote a healthy lifestyle through walking running and biking over driving. The sidewalks and trail system provide connectivity to both the numerous pedestrian sidewalks and the Baxter Creek “nature trail” as it extends to both the north and south of the property. Future development within West Side Flats is to maintain or exceed the connectivity and trails as planned within the West Side Flats Master Site Plan. Parking: Parking is important to the success of the West Side Flats Development. Due to our region’s inclement weather and the location of the project within the Bozeman community, driving will be a requirement for most users of West Side Flats. We have strived to provide adequate parking for the development and feel that the minimum requirements required by the Bozeman UDO is adequate. We have designed the development to encourage walking and biking that will lessen the need for parking stalls. In addition, we provide approximately 100% more bike parking than required to promote the use of biking over driving. The building design of West Side Flats also provides ample internal storage making bike ownership feasible to further encourage alternative transportation modes. No junk vehicle or non-running vehicles will be allowed in the West Side Flats Development. Due to the high demand of the parking stalls, no RV parking will be allowed in the development. Accessible parking spaces have been laid out so that each building entrance has a convenient and close assessable parking spot. All accessible parking stalls meet the “Van Accessible” parking standards for easy use by larger vehicles. Open Space: West Side flats provides for and exceeds the Bozeman open space requirements. Open space is provided adjacent to buildings for the enjoyment of the building users. When designing West Side Flats, we strived to create quality open space enhanced by landscape features and/or walking trails. Portions of open space is designed to be clear of landscaping to be utilized for play. In addition to ample common open space areas, West Side Flats provides for private outdoor open space in each of its planned 138 units. Site Lighting: Site lighting will be provided by LED zero cutoff night skies compliant wall sconces. Site lighting has been designed to minimize light pollution onto adjacent properties while providing 9 | P a g e minimum light levels for safety. Future phasing of development within West Side Flats may require parking lot lighting. If parking lot lighting is installed, it should be LED type and connect to the wall sconce lighting in photocell system. All exterior site lighting should match in color of fixtures (black or dark bronze) and LED color temperature. Led color temperature should strive to be in the mid or warm color range, 2500-3500K. Building Design: Building Materials: The building materials specified within the West Side Flats Development are intended to enhance and contribute to the overall character and success of the building design. Material selections should complement and contrast with one another and appear as high-quality materials. Where feasible materials should be low to no maintenance for a long-lasting quality appearance. Allowed materials include, cementitious siding, exposed concrete up to 34” above grade, 24 gauge corrugated metal siding, architectural asphalt shingles, 24 gauge standing seam metal roofing, stone, manufactured stone, stucco, metal accents such as awnings or bracing, exposed wood min dim of 6x6” nominal, and limited amounts of natural wood siding. Natural wood siding to be used as an accent only and should be limited to 20% of each façade accent area. Building Heights: Building heights are to follow the limitations as outlined in the Bozeman UDO for each zoning district. The Building Heights withing the R-O zoned West Side Flats Development is limited to 42’-0”at main roof ridges. Chimneys or roof screening mechanical chases can go 4’-0” beyond the roof ridge limitations. Roof Design: The rood design plays an important part in the overall appearance of the West Side Flats Design. West Side Flats is intended to resemble traditional roof forms seen throughout the western states countryside. 10 | P a g e Main roof forms should be provided with a min. of 6:12 roof slope. Secondary roofs will be allowed to be a low slope or flat roof form. No roof element is to exceed 40 feet without a break, interruption, or secondary roof element. Chimney elements play an important role in breaking the roof lines of West Side Flats. The Chimneys also provide a place to terminate and screen roof top penetrations such as plumbing vents. Where feasible all required roof penetrations should be routed to the open-air chimney element. Roof design elements that accentuate the roof design our encouraged, examples of these elements would be changes in roof materials, dormers, roof bracing, and chimneys. Roof eaves and soffits to be constructed with metal for a long-term quality appearance. Gutters and snow breaks are encouraged where water and snow fall off would interfere with the pedestrian areas around the building. All metal roofing must include snow breaks to hold the snow on the roof to discourage damage to the structure or private property. All roofs to be of 24-gauge prefinished metal materials. Building Massing: The West Side Flats building design is meant to create visual interest through varied massing of the building forms. Using a simple gable form and a smaller connecting roof gable form between the units, we created an interesting building design that is meant to mimic the simple forms of agricultural buildings within our region. The West Side Flats Design is meant to be a modern and clean lined interpretation of a simple agricultural gable formed building. Pedestrian scale entry roof elements help add a human scale to the common entries throughout the project. The single slope covered entries also help define entry points to the building while protecting the building users from the elements. Future Development within West Side Flats must meet the minimum design standards set fourth in Phase 1 of the development. Gable end walls are limited to 44 feet in width without a horizontal two-foot wall change. The remaining walls of the project must have a minimum two- 11 | P a g e foot undulation every 32 feet. Decks/Porches: Decks and porches throughout West Side Flats are intended to be used as private outside to indoor transition space for each apartment and should offer both functional outdoor living space as well as offer outside private space. Privacy at ground level patios will be provided by 32 high masonry walls. The low masonry wall while will allowing views from the internal portions of the apartments will act as a barrier between private and public space. Privacy at deck areas will be provided by 42” high nontransparent guardrails. The non-transparency at the decks will allow for neat appearing building façade without the clutter of outdoor furniture and miscellaneous storage use that occurs at private decks. No outdoor storage of bicycles, outdoor recreation equipment, or laundry will be allowed on patios and decks within West Side Flats. 12 | P a g e Exterior Lighting: Lighting will play an important factor in providing safety and visual interest for the project. Lighting in West Side Flats as planned is limited to Bronze LED sconce lighting & recessed lighting. All proposed and future exterior lighting must meet Bozeman UDC dark sky compliance and must not exceed light pollution maximums onto adjacent properties per Bozeman UDC standards. Parking lot lighting if provided shall meet City of Bozeman Standards. Parking lot light poles will be limited to 20’ heights as measured from grade. If provided all parking lot lighting shall be LED zero cutoff, connected to photocell sensors. Light poles will be installed on 18” min. diameter concrete bases 30” minimum above grade to protect light poles from vehicles. Landscape lighting accents and bollard lighting is allowed if the fixtures are LED type and meet UDC dark sky standards. Governing Codes and Bozeman UDO: These design guidelines do not take precedence over the Bozeman Uniform Development Code “UDO” or Governing Building Codes. These guidelines are to guide major design decisions and design intent within current and future West Side Flats development.
