Box 1230 Bozeman, MT 59771-1230 Re: Bozeman Gateway Site Plan Review Resubmittal – Boulders COB#: 21288 MMI#: 4192.025 Dear Sarah: This letter is to provide written responses to the comments stated in the DRC review memo dated August 30, 2021. Below are our responses associated with each comment. Section 3 – REQUIRED CODE CORRECTIONS All citations are to the Bozeman Municipal Code (BMC). Planning Division, Danielle Garber, dgarber@bozeman.net, 582-2272 1. Process and Submittal Requirements – A Site Plan Application is required for entitlement. If full buildout is expected to extend beyond 2 years a master site plan may be useful. Any requested departures must be submitted with the applicable review fees for each departure. Per Section 38.230 include the following in your submittal. a. Provide a phasing and construction management plan that will facilitate final occupancy of buildings, open space, parking, and other amenities for each phase. Provide open space, parking, and bicycle parking calculations per phase, as well as aggregate calculations. Buildings will all be built in one phase; a construction management plan has been included in this resubmittal b. Provide a color exterior material palette keyed to the building elevations. Include all siding, trim, roofing, windows, doors, balconies, railings, storefront, glass/glazing, walls, mechanical screening, trash enclosures, awnings and other architectural elements. Reference the A3 and A3.1 exterior elevation sheets for the material palette. c. A lot aggregation or lot line adjustment subdivision exemption application is required due to building 3 covering the existing lot line and cannot meet the form and intensity standards for R-4 zoning. A subdivision exemption has been submitted to Planning 3/28 to be concurrently reviewed with the site plan application d. Update the legal description for the formal submittal to be Phase 1 of Boulder Creek Subdivision, not Phase 2. Legal description has been updated in formal submittal 2. Setback Encroachments – BMC 38.350.050. Detail any proposed setback encroachments on the site plan. Upper level patios may not encroach into required setbacks. Like Phase 1 of Boulder Creek Apartments, the terraces and patios do not extend more than 5 feet into any required front or rear setback or two feet into the side setback. There is no more than 2’ overhang from the upper level patios. 3. Blocks – BMC 38.410.040.D. Pedestrian right of way to mitigate block length must be a city standard 5-foot wide concrete sidewalk. The landscaping plan labels this as a trail. Landscaping plan has been revised to call out 5-foot wide concrete sidewalk. 4. Block Frontage Standards – BMC 38.510. This project includes multiple block frontages: Special Residential internally and Landscaped along Abigail Lane and West Oak Street. See below comments regarding requirements for both frontages. When a building or buildings is located such that it faces and is adjacent to multiple block frontages, the orientation of the front of the building must be sited and placed on the property in the following order of precedence: a. Streets. b. Trail/Park. c. Special residential or internal roadway (parking areas/lots, block separation corridors). d. Departures may be considered provided the location and front orientation of the buildings are compatible with the character of the area and enhance the character of the street. The primary block frontage required for building 1 is the street frontage along Abigail Ln., and for building 2 is the street frontage along West Oak. These buildings must architecturally orient towards the street and provide a building entrance and pedestrian connection from the public sidewalk, see Landscaped Block Frontage below. Building 1 has been revised so that there is a pedestrian connection from the public sidewalk along Abigail. Building 2 during the concept review was located in Lot 4 and had street frontage along West Oak, however Building 2 has been relocated south of the parking lot and is now in Lot 3 5. Landscaped Block Frontage – BMC 38.510.030.C. Demonstrate compliance with this section in your formal submittal narrative and drawings including: a. Building placement. A 10-foot minimum front setback, or greater where necessary to accommodate easements is outlined in this provision and must be provided. Meeting. However, the site plan incorrectly states that there is a 20-foot rear yard setback along the north property line adjacent to Oak. This is in fact a front setback and block frontage. The site plan has been revised to indicate a 10 front yard setback along the north property line adjacent to Oak b. Façade transparency – Residential buildings, at least 15% of the entire façade (all vertical surfaces generally facing the street). Meeting, details provided on elevation sheets. All elevations have 19% façade transparency area or more. Reference calculations on A3 and A3.1 c. Building entrances – Building entrances must be visible and directly accessible from the street for all building ends facing a street. Buildings 1 and 2 need front facing entrances from Abigail and Oak. The site plan has been revised to provide building 1 an accessible entrance from the street. The location of Building 2 has been revised so that it no long fronts onto Oak Street. d. Weather protection – At least 3-feet deep over primary residential entries. Provide weather protection details on site or floor plans meeting this standard for primary residential entries. All entries have minimum 3’-0” deep cover. e. Parking location - Parking must be placed to the side, rear, below or above uses. For single and multi-building developments, surface and structured parking areas (ground floor) are limited to no more than 50% of the street frontage. Provide a metric on the site plan per this standard. This metric is included in the cover sheet as a part of the Parking Information. f. Landscaping - The area between the street and building must be landscaped, private porch or patio space, and/or pedestrian-oriented space. For setbacks adjacent to buildings with windows, provide low level landscaping that maintains views between the building and the street. Low level landscaping plants will be provided between streets and buildings 6. Special Residential Block Frontage – BMC 38.510.030.J. For residences with ground floor living spaces facing a sidewalk or pedestrian path in a residential or mixed use development, the building must feature at least one of the public/private space transition elements described below. The objective of this standard is to ensure privacy and security for residents, and an attractive and safe pathway that complements the qualities of adjoining residences within a residential complex. Detail in the narrative and drawings which transition elements are being employed in the site and building design. a. Raised deck or porch option. Provide at least a 60 square foot porch or deck raised at least one foot above grade. The porch or deck must be at least six feet deep, measured perpendicular to the building face. (The deck may be recessed into the unit floor plan so that deck does not extend from the building face a full six feet.) A low fence, rail or hedge, two feet to four feet high, may be integrated between the sidewalk or internal pathway and deck or porch. Front setback option is selected b. Front setback options. Provide a minimum ten-foot setback between the sidewalk or internal pathway and the face of the residence. Design options for the front setback: i. Landscaped area, meeting the provisions of division 38.550. ii. Semi-private patio space screened by a low fence or hedge (see section 38.350.060). The Front Setback option is selected. There will be a 10’ setback between sidewalk and residence face. The area will be landscaped with a screened semi-private patio space. c. Raised ground floor. If the residence's ground floor is a minimum of three feet above the grade adjacent to the building, then the landscaped area in option 2 above may be reduced to four feet wide (except where greater setbacks are specified for the applicable zoning district in division 38.320). Front setback option is selected. 7. Non-Motorized circulation and design – BMC 38.520.040.C.2. Sites with residential units. Provide direct pedestrian access between all ground related unit entries and a public street or to a clearly marked pathway network or open space that has direct access to a public street. Residential developments must provide a pedestrian circulation network that connects all main entrances on the site to other areas of the site, such as: a. Parking areas; b. Recreational areas; c. Common outdoor areas; and d. Any pedestrian amenities. Direct pedestrian connections to centrally located open spaces are required. See below for crosswalk requirements. Reference civil site plan for sidewalk connections between parking, recreational areas, common outdoor area, and pedestrian amenities. 8. Non-Motorized circulation and design – BMC 38.520.040.C.3. Crosswalks are required when a pedestrian path crosses the drive aisle and must contain contrasting material (such as concrete) and/or patterns (such as stamped asphalt), excluding painted surfaces. Detail materials proposed in the formal submittal. Provide a crosswalk wherever pedestrian paths cross drive aisles. Reference civil site plan for locations of cross walks at drive aisles. 9. On-Site Residential Open Space – BMC 38.520.060. All multi-household development, including multi-household portions of mixed-use development, must provide minimum usable open space equal to 100 square feet per dwelling unit for studio and one bedroom dwellings and 150 square feet per dwelling unit for dwellings with two or more bedrooms. The required open space may be provided in a combination of ways: a. Shared open space. One hundred percent of the required open space may be in the form of shared open space available to all residents and meeting the requirements of subsection B.2 below. Shared open space may be in the form of courtyards, front porches, patios, play areas, gardens or similar spaces. Provide amenities (benches, community garden, other types of seating, lighting, dog play areas, etc.) in the formal submittal. Also provide the landscaping, fencing, or architectural screening from the parking lot, and any ground level windows, mechanical equipment, and utility meters. Clarify if the open area to the south of the parking lot is proposed as open space or parkland. It does not meet the design requirements for dedicated parkland. Reach out to the Parks Dept. with any questions. If providing that space as usable open space see above requirements. Shared open space combined with balcony space is provided. Reference calculations on civil site plan. The open space includes seating area and separate fenced dog area, see landscape and civil site plans. b. Ground level private outdoor space. One hundred percent of the required open space may be provided by ground level outdoor space that is adjacent and directly accessible to the subject unit. Such open spaces must be enclosed by a fence and/or hedge at least 32 inches in height to qualify. Departures to this standards are permitted. Ground level patios used to meet open space requirement must meet this standard. All patios are enclosed by 32” height walls, see architecture plans. Ground level patios are included in open space calculations c. Balconies. Up to 50 percent of the required open space may be provided by private balconies provided they meet these requirements: such spaces must be at least 36 square feet, with no dimension less than six feet, to provide a space usable for human activity. See this section for units with balconies if counting towards the required total area. Delineate dimensions and area of each balcony on the floor plans. The balconies are over 36SF and 6’-0” in depth. Reference A2 and A2.1 for balcony dimensions. Reference civil site plan for open space and balcony calculations. 10. Location and design of service areas and mechanical equipment - BMC 38.520.070.C. The sides and rear of service enclosures must be screened with landscaping at least 5-feet wide in locations visible from the street, parking lots, and pathways. A full 5-feet is required the entire length of the sides and rear of the trash enclosures. Trash enclosures have been adjusted to provide 5’ wide areas for landscape screening. 11. Building massing and articulation – BMC 38.530.040.C. Residential buildings must include articulation features at appropriate intervals relative to the scale of the façade in order to reduce the perceived massing of the building and add visual interest. At least three of the features listed in this section must be employed at intervals relative to the individual dwelling units or at a maximum of every 30 feet. The scale of the façade articulation should be compatible with the surrounding context. Detail in the narrative and drawings which articulation features are being utilized. Windows, entries, weather protection features, roofline change and building material change are used to break up the massing of the building. A combination of horizontal lap siding and vertical corrugated siding is used. The roof shifts in height with gable roofs of different size and orientation, with shed roofs and canopies. 12. Building massing and articulation – BMC 38.530.040.E. Building façades wider than 150 feet must include at least one of the listed features in this section to break up the massing of the building and add visual interest. Detail in the narrative and drawings which articulation feature is being utilized for building 3. At the stairs, there is a 12’ wide extrusion in the building to break up the mass. At the patio side, there is a 12’ wide by 6’ deep extrusion. Roofline modulation is also used. 13. Number of parking spaces required – BMC 38.540.050.A.5.b. See this section for bicycle parking location and dimensional requirements. Bicycle parking must be within 50-feet of an entrance. Provide some bicycle parking on the south side of the south lot within 50-feet of an entrance. Bicycle parking is located next to each Phase 2 building within 50-feet of an entrance. 14. Landscaping – Section 38.550.050.C.2.a(2-4). (2) All parking lots located between a principal structure and a public street, must be screened from the public street, (3) The screening required under this subsection must be continuous and not less than four feet in width unless a different width is specified in 38.510.030; and (4) Screening must be maintained at a height of four to six feet except as otherwise restricted by fence and hedge height limits within required front setbacks and street vision triangles. Ensure landscaping used to screen parking areas meets this requirement. The west end of the parking lot will be screened from Abigail lane with a continuous 4-6’ hedge. 15. Lighting – BMC 38.570. Provide photometric site and elevation plans. Photometric site and elevation plans have been included in this resubmittal. Advisory Comments from Water Conservation. See attached memorandum. Engineering Division, Karl Johnson, kajohnson@bozeman.net, 406-582-2281 1. See attached memorandum. North Western Energy; Thomas Stewart, thomas.stewart@northwestern.com 406-582-4602 1. Will the new buildings require gas in addition to electric services? The new building will require electrical 2. There are both gas and electric utilities on the west side of Abigail Lane that can be extended across Abigail Lane. Any extension of utilities from the west side of Abigail Lane may require boring the utilities from the west side to the east side. Applicant will need to work with NWE engineer to determine the best path for bringing utilities into the project for best use of transformer locations to minimize utility equipment. Understood – the utility plan illustrates the proposed electrical layout, please advise. 3. Location of the transformers. If the building should require 3 phase power a transformer pad site should be planned. Typical 3-phase pad is going to be a 7’x7’ pad. For oil filled transformers a 2- foot clearance is required to non-combustible walls and surfaces that do not have any openings such as doors, windows, air intake, and fire escapes routes, and meets current NEC or NFPA requirements for non-combustible material. For transformers 750kVA & larger a 3-foot 6-inch clearance is required. For both locations, 10-feet of clearance is required on the front side of the pad where the transformer doors are located. Note, all distances are referenced to the edge of the pad. For any combustible surface, not meeting current NEC or NFPA requirements for non- combustible material, a minimum of a 10-foot clearance is required. For planting of bushes or shrubs a Minimum Working Space for a Pad-Mounted Transformer, is 4-feet on the sides and back portion of the concrete pad and 10-feet of clearance on the front side of the pad where the transformer doors are located. Note, all distances are referenced to the edge of the pad. The NWE project engineer will help to determine the appropriate location for the transformer. Due to COVID 19 there has been an impact on receiving larger three phase and single phase transformers and a longer timeline may be needed to receive the needed equipment for these services. Understood please advise if transformer location is acceptable 4. Applicant needs to show proposed meter locations & elevation plans showing the meter locations for the NWE project engineer to review. Reference exterior elevation on A3 for meter locations. 5. Service & Meter Location. NWE will need to review proposed location of gas and electric meters. The electric meter & or CT cabinet will need to be installed in the same general location within 10-feet of the gas meter. NorthWestern Energy reserves the right to specify the location of our meters. All meters are to be located outdoors on the corner or in a location on the building closest to the transformer or secondary junction can serving the building unit. On new construction, electric meter locations must be within 10 feet of the gas meter if NorthWestern Energy will be providing both electric and gas service. Meter locations will need to be approved by NWE. NWE policy is to maintain a minimum 30-inches wide by 3-feet clear zone between the front of the meter and landscape screening or wall screening for self-contained meter bases and 48-inches for installations requiring cabinets. Location of the meter(s) shall allow easy access to the meters for operation and maintenance. Gas meters. The following applies to all buildings in regards to the gas regulator. The gas regulator cannot be placed under a window or within 3’ of the operable portion of the window. It can be placed under a window/deck on the second story, provided the “open/operable” portion has at least 6’ of clearance from the regulator. Ensure that there is 10’ of separation from any mechanical air intake, including Page 7 of 8 air conditioning units. The regulator will need to be 3’ from the closest corner of any portion of the electric meter base. Understood 6. Where multiple units are proposed there will be a need to install multiple meters within the same location. With multiple meters, adequate wall space will be needed to install the number of electric and gas meters, and electric gear. For gas meters, NWE will only stack gas meters 2 high and therefore the needed wall space for gas meters will require a longer wall space. The two areas for gas and electric meters will need to occupy the same wall space, unless otherwise approved by a NWE project engineer, with the needed separation between gas and electric meters. Understood 7. When there are multiple units with multiple meters NWE requires that the meters have a permanent placard for each meter. For multiple metering each location or premise must have its address and unit numbers permanently attached by means of a placard to the meter bases and the individual apartment /unit breaker boxes before the meter is set. These identifying placards must match the unit information as displayed on the unit’s entry door. Understood 8. Applicant needs to show proposed meter screening methods for the NWE engineer to review. If using a screening wall a drawing of the screening wall need to be reviewed and approved by NWE for underground utility installation under the wall and access for operation and maintenance lines and equipment. Screening Wall criteria: a. Gas service cannot penetrate foundation walls that are attached to the building foundation per the International Fuel Code. Gas riser need to penetrate the building above ground. However, if the foundation is not attached to the building i.e. the foundation wall is isolated from the building for just supporting the wall, this is acceptable. b. If this is a free standing foundation wall, a knock-out must be provided that is a min of 2’x2’ but may be required that the knockout be larger on the electric service depending on the meter base amperage. Consult NWE for proper sizing of knockout c. Contact NWE for placement of knock-out to insure that it lines up properly with the termination location to prevent bends in the gas or electric services. d. Screening must meet the clear zone requirement of NWE Electric Service Requirements which typically for commercial application is 48” from the face of the electric meter. See meter location comment. e. Gas meter cannot be located in recessed location where it is not open atmosphere above the meter without approval from NWE. f. Screening cannot consist of rolling doors or other devices that are required to be open to access the meters. 9. Utility easement. Any extension of gas main or electric primary will need to be installed within an easement. To establish the needed utility easement locations the NWE project engineer and Northwester Energy’s real estate representative will help to establish these locations. Page 8 of 8 10. Landscaping. No large, deep rooted trees or bushes will be allowed within the 10-foot utility easement. No large trees reaching heights of 15-feet or taller will be allowed under any overhead distribution lines. All other approved landscaping will be placed so as not to damage, prevent or hinder operation and maintenance of NWE utilities. Noted. 11.
