1. Applicant Questions:
a. See Engineering comments
2. Process – A Site Plan Application is required for entitlement. Any requested departures must
be submitted with the applicable review fees for each departure. Per Section 38.230.100
include the following in your submittal.
a. Show all existing and proposed utility easements on the plans with the formal
submittal.
b. A color exterior material palette keyed to the building elevations (also see building
materials below).
c. Show utility meters, electrical conduits, mechanical equipment and other service
utility apparatus on the building elevations. Show appropriate screening on the
plans.
d. If the development phasing is to extend for a period beyond two years than a
master site plan is required. All phasing plans must include a construction
management plan. If the applicant is planning on acquiring occupancy building by
building, but not extending construction over 2-years, then a construction
management and phasing plan is still required with the site plan.
e. Provide all code calculations on the project cover sheet such as parking and open
space by phase. Each phase must be supported as a standalone project in the event
of non-completion. Open space may not be bisected by phasing lines and must be
fully provided with a particular phase as needed based on the required calculations.
The narrative states that the entire parking lot is to be constructed with phase 1,
this should be reflected on the phasing plan sheet.
3. Grading and drainage – BMC 38.410.080.H – Stormwater retention/detention facilities in
landscaped areas must be designed as landscape amenities. They must be an organic
feature with a natural, curvilinear shape. The facilities must have 75 percent of surface area
covered with live vegetation appropriate for the depth and design of the
retention/detention facility, and be lined with native grasses, indigenous plants, wet root
tolerant plant types and groupings of boulders to create a functional, yet natural site
feature. A cross section and landscape detail of each facility must be submitted with the
final landscape plan for review and approval. Facilities with a slope up to and including ten
percent grade may be grassed and irrigated to blend into the adjacent landscaped area.
4. Setback encroachments – BMC 8.550.050 - Delineate on the site plan the locations of upper
level patios to ensure that they do not encroach into setbacks.
5. Other block frontage – BMC 38.510.030.G – Demonstrate compliance with this section in
the narrative and plans according to the following standards:
a. Building placement
b. Building entrances – Currently not providing. At least one building entry visible and
directly accessible from the street is required. Staff recommends adding this entry
and sidewalk connection to Building 6.
Page 3 of 8
c. Façade transparency
d. Weather protection
e. Parking location
f. Landscaping
6. Trail/park frontages – BMC 38.510.030. Where a property fronts onto a park or a public
trail, such frontages must comply with the mixed block frontage standards set forth in
subsection D of this section. For non-residential developments/uses where the review
authority determines that an orientation to the trail would not be appropriate based on the
context of the site, the development must be subject to the standards for "other block
frontages" set forth in subsection G above, with a minimum building setback of 20 feet from
the applicable park/trail right-of-way, easement, or property line. A public trail is present to
the northeast of this proposed site plan adjacent to building 2. Due to the uses and
context of the site staff would support a frontage along the Other block frontage
standards, but this would require a 20-foot setback from the side property line behind
building 2 along the trail. Staff is happy to discuss options within this section of the code
prior to formal submittal.
7. Non-Motorized circulation and design – BMC 38.520.040:
a. For sites with multiple buildings, pedestrian paths or walkways connecting
businesses and residential entries on the same development site must be provided.
Routes that minimize walking distances must be utilized to the extent practical.
Provide direct pedestrian paths to building 4, as well as along the west drive aisle
and to the open space adjacent to that aisle.
b. Pathway Design. Pathways must be separated from structures by at least three feet
of landscaping except where the adjacent building façade meets the Storefront
block frontage standards per section 38.510.030.B. Departures are permitted for
other landscaping and/or façade design treatments to provide attractive pathways
will be considered. Examples include sculptural, mosaic, bas-relief artwork, or other
decorative treatments that meet the intent. Staff recognizes this is difficult where
walkways are adjacent to garage doors. Departures have been supported for past
projects where strategically placed planters were used in place of a continuous
strip of landscaping. Staff recommends reading the intent of this section prior to
formal submittal of any departure proposals.
8. 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. See B.2 in this section for
details on providing shared open space. The shared spaces at the center and the
Page 4 of 8
east side of the development must meet these standards and be separated from
parking lots, mechanical equipment, and ground level windows via landscaping or
fencing, the accepted width of the landscaping buffer is 2-feet. The intent of the
residential open space requirements is to create useable space that is suitable for
leisure or recreational activities for residents, not just placed in leftover or non-
developable areas.
9. Service areas & mechanical equipment, landscaping - BMC 38.520.070 – Provide details on
location and screening for any ground or roof mounted mechanical equipment. If proposing
to utilize PTAC or Mini-Splits screening is still required.
10. Service areas, landscaping - BMC 38.520.070.C.1. - Five feet of landscaping must be
provided to the sides and rear of any service area enclosure and adjacent streets, parking
lots, and pathways.
11. Building materials – BMC 38.530.060 – Demonstrate compliance with the siding
requirements in this section with the color exterior material palette.
12. Blank wall treatments – BMC 38.530.070 - Untreated blank walls visible from a public
street, pedestrian-oriented space, common usable open space, or pedestrian pathway are
prohibited. Methods to treat blank walls are listed in this section. Provide a blank wall
mitigation plan with formal submittal or provide additional windows where blank walls
are present.
13. Parking – BMC 38.540.050.A.1.b(2) – In order to utilize the mixed-use residential parking
reduction long term availability of the parking spaces upon which the use of this section is
based must be ensured to the residents of the project. Please detail how parking will be
managed. Limiting the stacked parking in front of roll up doors to commercial uses does not
ensure availability to residential users.
14. Mandatory landscaping provisions - BMC 38.550 – No landscaping plans were provided,
please see this section of the code and demonstrate compliance with mandatory landscaping
provisions with formal submittal.
15. Lighting – Section 38.570.040.C - demonstrate compliance with this article with any exterior
building mounted or parking area lighting.
16. Wetlands – 38.610 – Provide a wetlands delineation, survey, or report for review by the City
with the formal submittal to delineate or rule out the presence of any wetlands on site.

Will the proposed buildings need gas services along with the electric services?
Plans show 10-ft utility easements meandering through the property. The section of the
utility easement going between Building 3 and Building 5 is not an ideal location due to
future operation & maintenance. In addition, the over-excavation for the two building
foundations will be a problem as well. For buildings 1(a) and 1(b) the utility alignment
shown on the Civil plans does not allow for a good location for a transformer & pad.
Placing a transformer in a narrow corridor between two buildings is not ideal and should
be avoided. Extensions from junction cans to transformers or loop feed transformers to
other equipment needing primary will need to be installed within a minimum 10-foot
easement and the NWE project engineer will help to establish these locations.
Applicant needs to work with the NWE project engineer to determine utility stub locations
at the end of the phases to assure utilities can be extended into the next phase when the
next phase is constructed.
Landscaping. NWE does not allow large, deep rooted trees within the 10-foot utility
easement. All other approved landscaping will be placed so as not to damage, prevent or
hinder operation and maintenance of NWE utilities. Landscaping around and in front of
electric equipment and meters has to meet NWE standards.
Applicant will need to provide building elevation plans showing the proposed meter
location on the building for the NWE project engineer to review.
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.
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
Page 6 of 8
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 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.
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.
Applicant will need 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.
o 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.
o 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
o 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.
o 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.
o Gas meter cannot be located in recessed location where it is not open
atmosphere above the meter without approval from NWE.
o Screening cannot consist of rolling doors or other devices that are required to
be opened to access the meters.
Depending on the size of the buildings and electric loads or increasing the number of units
served on a transformer to reduce the number of transformers may require the use of
three phase transformers. Once the total electric loads are submitted to the NWE project
engineer the number and size of the transformers will be determined. If all the units will
be utilizing gas services this will reduce the electric load.
Page 7 of 8
Transformer location to Building. If the building will be requiring or to reduce the number
of transformers a 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.
If the utility infrastructure for all phases will not be completed as a part of the first phase
then, utility conduit stubs will need to be extended to the next phase for future extension
of gas and electric.
If the applicant has not done so, applicant needs to submit a service application to NWE
as soon as possible to get the NWE engineer working with the engineers and architects to
help correct any issues and provide direction and feedback as the process continues
through design. Go to www.northwesternenergy.com/construction to apply online
Montana Construction Application, and access Montana New Service Guide to provide
information on electric and gas service requirements.

ENGINEERING COMMENTS:
Applicant Questions
1. Does the water and sewer department approve of our proposed water service sizes and the
proposed water service reduction from 1.5" to 1" for the meter in the building? The friction loss
in the 1.5" line allows for proper flow over the proposed lengths while the proposed 1" meter
will match the anticipated water usage. -See Water and Wastewater comment 1.b.
2. Does engineering foresee any capacity issues for the proposed 5,091 gpd sewer flow. Using the
3.7 gpm per lot sewerage flow referenced in the 1999 Design report by TD&H, the anticipated
flow from this lot totals 5,328 gpd. – See Water and Wastewater comment 2.a.
General
1. Proposed site phasing - The phasing proposed by the applicant is inadequate. The applicant
must include full hardscape site plan characteristics with incorporation of full storm drainage
treatment and quantity considerations in the first phase of the project.
Easements
1. BMC 38.230.100 Plan Review Criteria - The applicant must review section 38.230.100.
Specifically, but not exclusively, show how future utilities (i.e. water, sewer, and electrical will
service the properties units) as well as any existing easements.
a. The applicant must call out the existing 30’ sewer easement shown on the plat along the
western property boundaries.
2. BMC 38.410.060 (B) (2) Easements - The applicant must provide a ten foot utility easement

Storm water
1. DSSP Section II (A) (4) Water Quality - The applicant must include a drainage plan with post-
construction storm water management controls that are designed to infiltrate, evapotranspire,
and/or capture for reuse the post-construction runoff generated from the first 0.5 inches of
rainfall from a 24-hour storm preceded by 48 hours of no measurable precipitation. For projects
that cannot meet 100% of the runoff reduction requirement, the remainder of the runoff from
the first 0.5 inches of rainfall must be either: a. Treated onsite using post-construction storm
water management control(s) expected to remove 80 percent total suspended solids (TSS); b.
Managed offsite within the same sub-watershed using post-construction storm water
management control(s) that are designed to infiltrate, evapotranspire, and/or capture for reuse;
or c. Treated offsite within the same subwatershed using post-construction storm water
management control(s) expected to remove 80 percent TSS.
2. DSSP Section II (C) Water Quantity - The applicant must provide on-site detention with release
rates limited to predevelopment runoff rates and with respect to the subdivision storm water
planning. Retention ponds must be sized based on a 10-year, 2-hour storm intensity.
3. Montana Post-Construction Storm Water BMP Design Guidance Manual (Seasonal High
Groundwater) - The proposed project is located in an area that is known to have seasonally high
groundwater. Engineering recommends that the applicant confirm that groundwater will not
impact the function or maintenance of the proposed facilities. Industry guidance recommends a
three-foot minimum separation from the bottom of the proposed facility to the underlying
groundwater table.
a. It should be noted that the subdivision storm water report was completed with no
consideration of ground water fluctuations and corrections for seasonal groundwater
levels should be applied to the subdivision storm water volumes.
4. BMC 38.540.020 (M) - The applicant must identify snow storage areas on the Site Plan for the
parking area. Snow removal storage areas must be sufficient to store snow accumulation on
site. Such areas shall not cause unsafe ingress/egress to the parking areas, shall not cause snow
to be deposited on public rights-of-way, shall not include areas provided for required parking
access and spaces, and shall not be placed in such a manner as to damage landscaping.
Water and Wastewater
1. DSSP Section (V) (A) Main Size - A water design report must be prepared by a professional
engineer for the proposed project. The water distribution system must be designed to meet the
maximum day demand plus fire flow and the peak hour demand.
a. BMC 38.410.070 (B) (2) – The length of service lines from the main to the structure may
not exceed 150 feet in length, unless approved in writing by the city. A dead end water
main extension DSSP Section V A.5 should be extended into the property to serve the
site buildings.
b. Service line reductions to 1” at the meter are acceptable.
2. DSSP Section (V) (B) Sanitary Sewer System Design Criteria - The applicant must provide an
estimate of the peak-hour sanitary sewer demand for the different phases certified by a
professional engineer for the proposed project prior to Phase 1 site plan approval. This
information is used to verify downstream sewer capacity as well as keep the City’s wastewater
hydraulic model updated.
a. The applicant has shown sewer services connecting to the 20” trunk main along the
western property boundary. These services may not connect to the trunk main. All
services to the development must connect to the 10” sewer main bordering the North
East perimeter of the property. The 20” trunk line is scheduled to be replaced as part of
CIP planning in fiscal year 2023.
b. The applicant provided an estimate of 5,091 gpd sewer flow from a professional
engineer. Although the quantity reported is less than the 5,328 gpd reported for the lot
in the subdivision report, the subdivision report was designed under non-residential
assumptions. The applicant must report the peak-hour sanitary sewer demand for the
development under the employment of the metrics outlined in the DSSP and the City
Wastewater Facilities Plan. Engineering does not forsee any capacity issues for the
subject development.
Transportation
1. BMC 38.220.080 (A) Traffic Generation - An estimate for the development’s peak-hour trips as
well as the assumed peak-hour trips for this development from the subdivision’s traffic impact
study must be provided. If the development will significantly exceed the original assumed trip
estimate, the assumptions and conclusions presented in the traffic impact study may need to be
reviewed to determine if any additional mitigation is required. The review must be performed
by a professional engineer registered in the state of Montana.

Cherry Creek Mixed Use – 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 Cherry Creek Mixed Use 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 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.
