Response: (PA) Refer to Page 2 of the PROOF Architectural Narrative and Departure Request Letter attached to the end of this document. • BMC 38.410.040.D. Rights-of-way for pedestrians. Rights-of-way not less than ten feet wide for pedestrian walks are required where deemed necessary to provide circulation or access to parks, open space, schools, playgrounds. . . The pedestrian pathway that is proposed running north south satisfies this provision and as proposed is of adequate width (greater than 30 feet). However it will need to be built to city standards per 38.410.040.D.3 which includes street trees. In addition, per 38.410.040.D.1 the setbacks from the pedestrian easement will be required. A pedestrian access easement will be required per 38.410.060. Response: (ME) - Acknowledged. A 30’ wide easement is proposed and shown on the site plan. (RB) – Due to the sewer line running parallel to the curb. Trees need to have 10’ separation from water/sewer lines. Currently trees are being showed on the East side of sidewalk that could satisfy this requirement. • BMC 38.510.020.F.(1 & 2) When a building or buildings is located such that it faces and is adjacent to multiple street block frontages, the orientation of the front of the building must be sited and placed on the property in the following order of precedence: (1) Gateway. The buildings whose ends are facing Davis Lane (Building E & I) will need to be designed such that the façade facing Davis presents and functions as a front facing façade including the sidewalk connecting north of the 4-Plex (just south of the proposed stormwater pond). Response: (PA) Refer to Page 3 of the PROOF Architectural Narrative and Departure Request Letter. • BMC 38.510.030.C. The internal drives will need to be designed to the landscape block frontage with. i. Ensure you provide façade transparency calculations on the elevations for the buildings in future submittals. ii. 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. Also provide plant materials that screen any blank walls and add visual interest at both the pedestrian scale and motorist scale. For extended wall areas, provide for a 4 | P a g e diversity of plant materials and textures to maintain visual interest from a pedestrian scale. Ensure these provisions are met on future submittals. Response: (PA) Refer to Page 3 of the PROOF Architectural Narrative and Departure Request Letter. • BMC 38.510.030.J. Special residential block frontage standards along sidewalks and internal pathways. Project will need to meet this section for buildings that face a sidewalk or pedestrian path. Response: (ME) The project has been designed per BMC 38.510.030.J. • BMC 38.540.020. Stall, aisles, and driveway design: Dimensions of parking spaces and modules. Show the actual dimensions for your parking stalls. Note the dimension requirements in 38.540.020 (18’ x 9’) except in residential garages which required 20’x9’ (note an additional one foot is required on all exterior sides of the stall). Response: (ME) Parking stalls and aisles dimensions are called out on sheet C1.1 Dimension plan. • BMC 38.540.020.D. Backing requirements.

Drought tolerant species required. A landscape plan must provide 75% or greater of the proposed trees and shrubs as drought tolerant species as defined in the latest edition of the Montana Nursery and Landscape Association’s Drought Tolerant Plants for the Montana Landscape or on a list adopted by the city of drought tolerant species for purposes of this section. Response: (RB) The landscape plan has been prepared per the City of Bozeman 5 | P a g e requirements. • BMC 38.550.050.J. Required use of trees with residential adjacency. All landscape plans must include, for each setback with a residential adjacency, at least one canopy or non-canopy tree for each 50 lineal feet of the adjacent areas. This will need to be met for internal streets as well. Response: (RB) Trees have been added to the boulevard strip on the South side of buildings 6 & 7, however the other internal street on the North side is all driveways, so I am unable to add street trees. We are showing 3-4 trees here where there is plant beds or lawn but will need 7 total to meet the 50 LF requirement. Parks Department • A parkland calculation table is required to determine parkland, or CILP • See Sec. 38.700.130 for calculating Net Residential Density: • Cash-in-lieu of Parkland (CILP) appraisal value is currently $2.07 PSF (effective June 22, 2021). • Provide written justification for CILP request, per Resolution 4784 • All CILP requests are reviewed by the Rec and Park Advisory Board or its Subdivision Review Committee upon formal Site Plan submittal. Final CILP approval is granted by Parks and Rec Director. • See sections 38.700.130 and our general 38.420.010 for more information. Response: (ME) The parkland calculation table is located on sheet C0.0 – Cover. References above have been reviewed Northwestern Energy • Will the new buildings require gas in addition to electric services? Response: (ME) Yes gas is proposed in addition to electrical service • 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. • Transformer location to Building. Plans do not show proposed transformer locations. Location of the transformer will need to be installed where large line trucks can access the transformer location for installation and service or repair. 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 6 | P a g e 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. • 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 air conditioning units. The regulator will need to be 3’ from the closest corner of any portion of the electric meter base. • 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. • 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 7 | P a g e 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. • 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. Response: (ME) The comments above are acknowledged. Screening Wall criteria. • 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. • 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 knock-out • 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. • 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. • Gas meter cannot be located in recessed location where it is not open atmosphere above the meter without approval from NWE. • Screening cannot consist of rolling doors or other devices that are required to be open to access the meters. • 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. • 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. 8 | P a g e All other approved landscaping will be placed so as not to damage, prevent or hinder operation and maintenance of NWE utilities. • Submit an application online to have the project engineer work with the applicant through NWE engineering standards and processes.

Water Conservation Comments Autumn Grove Condominiums – Landscape and Irrigation Conceptual Plan Advisory Comments The Water Conservation Division strives to promote outdoor water-use efficiency and best practice of landscape and irrigation installations. The following best practice recommendations to the Autumn Grove Condominiums conceptual plan are provided to guide the project towards maximizing landscape health and resiliency while minimizing outdoor water consumption. Adhering to these recommendations is not required to receive plan approval. 1. The landscape design plan should indicate the total landscaped area (ft2) and landscaped area of all turf grass areas. 2. Each hydrozone should be on a separate irrigation zone based on the vegetation’s water 13 | P a g e demand. Grouping plants with similar watering needs will reduce over or under watering the vegetation. 3. Drought tolerant and water-wise landscaping can use approximately 75% less irrigation water than turf grass. The plant schedule should maximize the installation of drought tolerant landscaping and minimize the use of Kentucky bluegrass, especially within areas surrounded by pavement and/or parking spaces. It is recommended to install native seed mix and/or drought tolerant plants/shrubs in these areas. 4. Landscape plans should include topsoil depth specification of 4”- 6” (after grading) to allow for proper root depth growth and assist with plant and turf grass resiliency. 5. Specify that perennials, shrubs, and trees will be irrigated using low flow drip irrigation technology that will directly target the roots. Drip irrigation uses approximately 75% less water when compared to overhead spray irrigation. 6. Multi-spray, multi-trajectory (rotary) nozzles can reduce water loss from evaporation and wind drift by up to 50%. Specify the installation of water efficient sprinkler nozzles (multi- spray, multi-trajectory nozzles or rotary nozzles’) if overhead irrigation is to be used within turf grass lawn areas. To save money and water - check out the City’s sprinkler nozzle rebates for new construction! 7. When programmed properly, weather based irrigation controllers can reduce outdoor water use by 25%. Specify the installation of a weather based irrigation controller that can automatically adjust the watering schedule according to local weather events. To save money and water - check out the City’s WaterSense® weather based irrigation controller rebates for new construction! 8. Rain sensors can reduce outdoor water use by approximately 10%! Specify the installation of a rain/freeze sensor, which overrides and turns off the irrigation system when a certain amount of rain has fallen. When the sensor dries, it opens the connection to allow the system to resume normal operations. To save money and water - check out the City’s rain sensor rebates for new construction! 9. Overhead sprinkler heads should be installed upright in the ground and ~2”-4” from any paved surface, especially curbs, to minimize sprinkler head damage from snowplows and lawn care equipment. This will also help to minimize future pavement obstruction of the sprinkler head which can occur as the ground settles over time. 10. After installation, sprinkler heads should be adjusted to throw the proper distance and direction in order to minimize water waste via run-off and achieve head-to-head coverage. Response: The landscape, plan has been prepared per the City of Bozeman requirements. END OF NARRATIVE
