Hi Alicia-
In regards to that comment, please see attached for the subdivision approval for Park View Crossing
Major Subdivision, that was reviewed & approved with this bit of land that we are updating the zoning
on now. I also included the plans so you can see where this is in relation to the ZMA piece, as well
as the infrastructure approval and the corresponding engineering report to show that the
water/sewer/traffic was already reviewed & approved on this.
Let me know if you have any questions on this, or if you need anything else from me.
Thanks,
Brett Megaard, PE

Good Morning Audrey and Tom-
I was just checking in PDox and saw that everything on this is completed besides planning &
engineering review, where do we sit on that? Is there anything I can do to help move this along?
Thanks again for your guys' help, I do appreciate it.

Hi Tom-
See attached for our ZMA map, narrative & noticing pieces. Since I didn't have a task open on my

Brett,
Thanks for your response and comments. In no particular order:
6
You are correct, the property is annexed. No annexation map required. I apologize for the
confusion/concern
I see the editable metes and bounds description, all set
Please prepare a Zone Map with the details listed in the ZMA Checklist
The Commission needs the narrative addressing the State required zoning criteria in sufficient detail
to make appropriate findings.
The notice pieces are also required, State requirements we cannot waive.
If you have any questions please let me know.

Hi Tom-
Thanks for your notes, I do appreciate it. I do have a couple questions/comments based on
those;
- The application does include the editable legal description, I double checked to make sure I
didn't accidentally forget it
- When Chris & I were going back and forth, I was under the impression that the legal
survey that was already recorded for the land swap would suffice for the 'map' side of things
- I was also under the impression that this chunk was already technically annexed into the City
based on the land swap, but I could definitely be off on that.
- As far as the narrative piece goes, I included a cover letter with the application as this seems
pretty straight forward in terms of a ZMA goes. Considering that we requested this be done
years ago and the legal side of the land swap has been recorded for a couple of years now, I
thought this would suffice as the lot has already been updated.

I will get the noticing side of things wrapped up here shortly but would you just like that emailed
over to you since I don't have an open task?
Let me know your thoughts or if you have any questions for me.

Brett,
The Development Review Committee is scheduled to consider the application next Wednesday, February
26. Comments will be provide after the meeting.
However, I noticed a number of required documents that were not provided with the submittal. These are
required before the City can consider the application. I know Chris S. provided this informational and it is
outlined in the Annexation and associated ZMA applications. We require:
· Annexation map
· ZMA map
· Narrative for annexation policy
· Narrative for the ZMA
· Notice requirements
· Notice addresses
· Editable legal description
There may be other requirements that I have not fully considered until I hear from the other DRC members.

EXECUTIVE SUMMARY
Unresolved Issues
Unresolved issues at this Preliminary Plat stage are related to parklands contributions and
stormwater/water quality management issues which must be resolved prior to submittal of

conditions of approval and all relevant Bozeman Municipal Code (BMC) code provisions
noted on pages 10 through 21 of this report.
Project Summary
This report is based on: (1) the September 24, 2021 revised plat maps; (2) the November 19,
2021 revised application documents; (3) the November 19, 2021 Development Review
Committee recommendation for conditions and code provisions; (4) the December 20, 2021
Community Development Board recommendation; (5) the Applicant’s December 23, 2021
withdrawal of a sidewalk variance request; (6) the December 27, 2021 staff report to the City

statutes and relevant Bozeman Municipal Code (BMC) subdivision statutes described in this
report.
Application. The property owner/Applicant made application to develop the vacant
property on the west side of Vaquero Parkway, south of Baxter Lane, north of W. Oak Street,
west of Davis Lane and east of the Gallatin County Regional Park. The application proposes
the subdivision of 7-acres into 47 lots: 44 residential lots consisting of nine fourplex lots, two
triplex lots and one duplex lot; one common area stormwater facility lot; two common open
space (mid-block crossing) lots; and associated streets and rights of way. Off-site
improvements by the Applicant include a shared-use pathway along the west side of Vaquero
Parkway along the subdivision’s frontage as partial fulfillment of his parkland contributions.
The two mid-block crossing open space lots would be publicly-accessible and owned and
maintained by the Homeowners Association (HOA). The stormwater pond lot would be
owned and maintained by the HOA.
The subject property was annexed to the City in 2000 and is zoned R-3, Medium-density
Residential District. The property is currently vacant and includes limited natural features.
Montana subdivision law requires Applicants to provide information about wildlife and
habitat that may be affected by the subdivision. A small section of the Spring Ditch irrigation
facility is located near the northern property boundary and encroaches into the northern
portion of the subdivision’s stormwater easement. The Spring Ditch agricultural water
facility would continue to flow and the existing irrigation easement located completely within
the adjacent Gallatin County Regional Park would not be abandoned or altered with this
subdivision.
A neighbor of the proposed subdivision commented that a flock of partridges are frequently
seen wandering about the Site and the adjacent 97-acre Gallatin County Regional Park. She
asked if the Applicant conducted an environmental impact study to determine the effect of
the development on these avian neighbors. The Applicant provided information regarding
wildlife on the Site (see page 25 of this report). In response to this public inquiry, staff
researched the Montana Natural Heritage Species of Concern and Potential Species of
Concern lists and found that the partridge species of bird is not a Species of Concern and,
therefore, is not subject to mitigation should their habitat be altered or removed.
Due to the State Legislature’s passing of HB 259, MCA Section 76-3-514 prohibits the
requirement for a subdivision to provide affordable housing per BMC Section 38.380 and this
subdivision does not provide such affordable housing. However, the subdivision provides a
mix of residential lot sizes and configurations which offer a mix of townhouse sizes and, one
would expect, prices. All lots are in compliance with the R-3 zoning. Eighteen of the lots are
sized to accommodate the addition of an Accessory Dwelling Unit (ADU).
The subdivision is proposed for on- and off-site private and public infrastructure and utility
construction in a single phase.
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 4 of 44
Prior to issuance of a building permit for an individual lot, completion of required on- and off-
site infrastructure and utilities for the subdivision is required, as is payment of impact fees
and sketch plan review of proposed structures on the lot.
Neighborhood centers are required for subdivisions of 10-acres or more per 38.410.020. This
subdivision is 7-acres and, therefore, exempt from this requirement. However, the County
Regional Park abuts the subdivision along its western frontage.
The subdivision’s 44 homes would require 1.31-acres of parkland per BMC 38.420.020.A. The
Applicant proposes to meet this requirement by providing both cash-in-lieu (CIL) and
parkland-related improvements-in lieu of parkland within the subdivision, due to the
proximity of the Site to the 97-acre Regional Park. One of the improvements would be the
installation of a 10-foot wide, paved, shared use path along the subdivision’s eastern frontage
within the Vaquero Parkway right-of-way (ROW). The Recreation and Parks Department
continues to work with the Applicant to enable him to satisfy this requirement; please see
Condition of Approval No. 2.
The Community Development Board, acting as the Planning Board, held a public hearing on
the application on December 20, 2021. The Planning Board is the advisory body to the City
Commission on this subdivision application. The Board, by a vote of 6 to 1, recommended
approval of the project with the conditions and code provisions outlined in this staff report.
One public comment expressing concern about increased traffic and parking congestion on
Vaquero Parkway was received during the Board public comment period. The Community
Development Board/Planning Board proceedings may be viewed here under the date
December 20, 2021: https://www.bozeman.net/services/city-tv-and-streaming-audio
Pursuant to BMC 38.240.130A.5.a.(4), Preliminary Plat, the final decision for a Major
Subdivision Preliminary Plat with less than 50 lots must be made within 60 working days of
the date it was deemed adequate. The Development Review Committee (DRC) deemed the
application adequate for continued review on November 19, 2021. The City Commission was
required to approve, conditionally approve or deny the subdivision application by January
19, 2022, unless there is a written extension from the developer, not to exceed one year. The
City Commission hearing to consider this preliminary plat was scheduled for January11,
2022. The Applicant provided a written request to postpone the hearing until the January 25,
2022 City Commission hearing. This was granted by the City Commission on January 11, 2022
and the application was re-scheduled for their January 25, 2022 hearing. The January 25,
2022 hearing was held in the City Commission chambers, 121 N Rouse Avenue at 6 pm as well
as on Webex.
No member of the public spoke at the hearing.
After the City Commission reviewed and considered the application materials, staff report,
advisory review board recommendations, previous public comment, and all the information
presented, they made individual findings and voted 3 to 0 to approve the motion to approve

the application. The Commission agreed that the application met the criteria established by
the Bozeman Municipal Code. Therefore, the application was approved with conditions and
applicable code provisions outlined in these findings.

SECTION 2 – REQUESTED VARIANCES
There are no variances requested with this subdivision application.
SECTION 3 - RECOMMENDED CONDITIONS OF APPROVAL
The following conditions of approval and code provisions satisfy City and relevant State
requirements as well as site-specific mitigation for potential adverse impacts associated with
development of the proposed subdivision. The conditions of approval are in addition to the
required code provisions identified in this report. The conditions are specific to the
preliminary plat application. The City Commission considered the impacts as identified in the
staff analysis and application materials and finds that the conditions of approval are deemed
reasonably-related and roughly-proportionate to the development of this subdivision.
1. BMC 38.400.110. Transportation Pathways. Concurrent with the Applicant’s
construction of the west side of Vaquero Parkway along the subdivision’s frontage, the
Applicant shall install a paved ten-foot wide “shared-use path” along the east side of the
subdivision within the Vaquero Parkway right-of-way (ROW). The shared-use path shall meet
City standards. The Applicant is advised that the City of Bozeman will accept responsibility
for the maintenance of this shared-use path within the Vaquero Parkway ROW once the path
has been installed, inspected and accepted by the City. Details of this shared-use path shall be
submitted with the final plat application.
2. BMC 38.420.020 and 080, Parkland Mitigation.
a. Park improvements or parkland improvements-in-lieu required by 38.420.020 and 080
and the Bozeman Parks, Recreation, Open Space and Trails (PROST) Plan must be approved
by the Park and Recreation Department (PARKS) prior to final plat approval or an
improvements agreement for such shall be executed. Applicants may not financially
guarantee the requirements per 38.420.080.A.1 and 2.
b. The shared-use path along the Vaquero Parkway west side ROW may extend further north
and south of the subdivision frontage as part of the Applicant’s parkland cash-in-lieu and
parkland improvements-in-lieu negotiated with PARKS, pursuant to BMC 38.420.020. Final
details of the Applicant’s parkland cash-in-lieu and parkland improvements-in-lieu
commitments must be provided with the final plat application submittal.
c. Documentation of compliance with the parkland dedication requirements of Section 38.420
must be provided with the final plat. A table showing the parkland requirements for the
subdivision and the method of meeting the parkland dedication must be included on the final
plat Conditions of Approval sheet. The table shall explicitly state (1) the parkland
requirements of the subdivision; (2) the methods for satisfying this requirement ( e.g. cash-
in-lieu (CIL) or improvements-in-lieu); (3) how much parkland credit was allocated for each
lot within each phase; (4) all areas within the subdivision qualifying for exemption from
parkland requirements (i.e., detention/retention areas, watercourse setbacks, wetlands,
common open space, parking facilities); and (5) the total area of each above category. The
table and its contents must be approved by PARKS.

Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 11 of 44
d. Where CIL has been accepted in-lieu of parkland, the amount of the cash donation must be
paid prior to final plat approval and must be stated on the final plat sheet.
3. 38.400.080.B. Sidewalks adjacent to public lands. The sidewalk along the west side of
Stokes Lane shall be built to City standards as part of the subdivision public improvements.
The applicable City standard sidewalk on the west side of Stokes Lane must be shown on the
plat sheets at final plat application submittal and must be shown on infrastructure plans prior
to infrastructure approval.
4. BMC 38.240.130.A.5.e (1) (a), Compliance with survey requirements. The proposed
perimeter lines of the subdivision do not match the most recent plat for the subdivision
(Minor Subdivision No. 400, Lot 4). However, a recent Subdivision Exemption Application, No.
20312, proposes a land swap to adjust these lot lines. That lot line adjustment consists of
relocating the common boundary between the two lots allowing the County to have more area
at the northern access point from Baxter Lane, and Lot 4 (this subdivision land area) to have
a more aligned tie-in/approach with the newly constructed intersection of Vaquero Parkway
& Tschache Lane. That revised plat, per Application 20312, must be recorded prior to final
plat approval. A digital copy of the recorded plat must accompany the final plat submittal.
5. Public Infrastructure Payback Obligations. Prior to final plat approval, the Applicant
shall pay the appropriate “pay back” cost for the N. 19th and Baxter Intersection Payback
District traffic signal improvements. The subject property lies within this District and the
owner did not participate in the original cost of construction of improvements and, therefore,
the current owner will be assessed a payback charge which must be paid prior to final plat
approval. The Applicant must contact the City Engineering Department
(kajohnson@bozeman.net) for a determination of the payback amount.
6. City of Bozeman Resolution 5076, Policy 1 - The Applicant must provide and file with
the County Clerk and Recorder's office executed Waivers of Right to Protest Creation of
Special Improvement Districts (SID’s) on City standard form for the following:
a. Street improvements to N Ferguson Avenue between W Oak Street and Kimberwicke Street
including lighting, signalization, paving, curb/gutter, sidewalk, and storm drainage.
b. Street improvements to Davis Lane between Baxter Lane and Kimberwicke Street including
lighting, signalization, paving, curb/gutter, sidewalk, and storm drainage.
c. Intersection improvements at Vaquero Parkway and Baxter Lane including lighting,
signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage.
d. Intersection improvements at Caspian Avenue and Baxter Lane including lighting,
signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage.
e. Intersection improvements at Tschache Lane and Davis Lane including lighting,
signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage.

Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 12 of 44
f. Intersection improvements at Flanders Mill Road and Baxter Lane including lighting,
signalization/channelization, paving, curb/gutter, sidewalk, and storm drainage.
The document filed must specify that in the event an SID is not utilized for the completion of
these improvements, the developer agrees to participate in an alternate financing method for
the completion of said improvements on a fair share, proportionate basis as determined by
square footage of property, taxable valuation of the property, traffic contribution from the
development, or a combination thereof. The Applicant must provide a copy of the recorded
SID waiver prior to final plat approval.

Applicable Subdivision Review Criteria for City Advisory Board and City
Commission Action on a Preliminary Plat per Bozeman Municipal Code
(BMC) Sections 38.240.150.A.2. In considering applications for preliminary plat
subdivision approval under this title, the City Commission shall consider the following review
criteria.
1. BMC 38.240.150.A.2 and Montana Codes Annotated (MCA) Section 76-3-615,
Public comments or documents presented at or prior to the City Commission’s
consideration of a plat constitutes new information.
Staff Evaluation: No new information has been presented to the City Commission prior to
their January 25, 2022 decision. At that hearing, the staff report, staff presentation, and
Applicant representative presentation was entered into the record. In the staff report, public
comment received to date was described as follows:
2. BMC 38.240.150.B. The basis for the City Commission's decision to approve,
conditionally approve or deny the subdivision must be whether the subdivision application,
public hearing if required, planning advisory boards and agencies advice and
recommendation and additional information demonstrates that development of the
subdivision complies with the Bozeman Municipal Code (BMC), the City's growth policy as
described in the Bozeman Community Plan, the Montana Subdivision and Platting Act and
other adopted state and local ordinances, including, but not limited to, applicable zoning
requirements.
Staff Evaluation: The Preliminary Plat meets these criteria as noted below on pages 24 to
36.
3. BMC 38.240.050.B.2. Consider written comments from appropriate public
agencies, utilities or other members of the public.
Staff Evaluation:
a. The Development Review Committee (DRC) reviewed this application and deemed it
adequate for further review and public notice on November 19, 2021.
b. The Community Development Board, acting as the Planning Board, reviewed this
application on December 20, 2021 and, by a vote of 6 to 1, recommended approval of the
preliminary plat with staff-recommended conditions and code provisions. The Board’s
recommendation did not include support of the Applicant’s sidewalk variance request.
Subsequent to the Board’s recommendation, on December 23, 2021, the Applicant withdrew
in writing his sidewalk variance request. It is noted that Condition of Approval No. 3 for this
Preliminary Plat requires a code-complying sidewalk along the west side of the new Stokes
Lane.
c. Public Comment.

Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 23 of 44
(1) During the December 20, 2021 Community Development Board meeting, a neighbor of
the proposed subdivision called in to comment on the application and described his concern
with increased traffic and parking congestion along Vaquero Parkway due to the proposed
development.
(2) A December 21, 2021 Bozeman Daily Chronicle newspaper article about the December
20, 2021 Community Development Board meeting alerted a neighbor of the proposed
subdivision and this neighbor called the Community Development Department to express her
concern with potential loss of habitat for a local flock of Partridge birds who frequent the Site
and neighboring park. The application material for this project noted that there are not
Species of Concern located on or near the Site. Staff reviewed the Montana Natural Heritage
Program website listing of Species of Concern and found that Partridge birds are not a Species
of Concern and, therefore, the loss of 7-acres of habitat does not need to be mitigated.
Furthermore, several site visits by staff after the neighbor’s alerting to the presence of these
birds, did not reveal the birds on the Site. It is noted that these visits took place in winter and
the snow on the ground made it easy to see a brownish bird. Only Macaw birds have been
observed on the Site.
4. BMC 38.240.150.B.3. The City Commission shall consider the following:
(a.) Relevant evidence relating to the public health, safety and welfare;
(b.) Other regulations, code provisions or policies in effect in the area of the proposed
subdivision;
(c.) The recommendation of the advisory bodies;
(d.) Any relevant public comment; and
(e.) Individual phases, existing conditions, and changed circumstances for any phase
reviewed under 76-3-617 MCA.
Staff Evaluation:
(a) Please see code evaluations noted on pages 22 through 36.
(b) Please see code evaluations noted on pages 22 through 36.
(c) Please see the recommendations noted on pages 1 and 2;
(d) Please see the public comments noted above;
(e) The subdivision infrastructure and utilities would be built in a single phase.
4. BMC 38.240.170, Certification that water and waste services are to be provided.
Staff Evaluation: Per the Engineering Report for this subdivision, water and wastewater
improvements would be designed to meet City standards and, with the recommended
conditions of approval and code provisions, this subdivision would not significantly burden
City water or sanitary sewer infrastructure.
5. BMC 38.240.150.B, Features, including well isolation zones, do not encroach
onto private property.
Staff Evaluation: Please see the Surface Water discussion below.

38.240.150. D, Finding of Fact. Federal or state governmental entity input. If a federal,
BMC or state governmental entity submits a written or oral comment or an opinion regarding
wildlife, wildlife habitat, or the natural environment relating to a subdivision application for
the purpose of assisting a governing body's review, the comment or opinion may be included
in the governing body's written statement under this section only if the comment or opinion
provides scientific information or a published study that supports the comment or opinion. A
governmental entity that is or has been involved in an effort to acquire or assist others in
acquiring an interest in the real property identified in the subdivision application must
disclose that the entity has been involved in that effort prior to submitting a comment, an
opinion, or information as provided in this subsection.
Staff Evaluation: No such comment was received for this application.
BMC 38.220.060, Documentation of Compliance with State and Local
Adopted Standards.
BMC 38.220.060 A. Staff offers the following summary comments on the information
required with BMC 38.220.060.
38.220.060. A.1. Surface Water. A small section of the Spring Ditch is located near the
northern property boundary and encroaches into the northern portion of the subdivision’s
stormwater easement. The original source of the Spring Ditch was believed to be from a
natural spring located south of what is now the County Regional Park. Currently the water is
collected underground (reportedly via a French drain system under Oak Street) and
discharged to a pipe located in the bottom of the man-made Spring Ditch channel. The channel
then flows north and crosses Baxter Lane. An existing irrigation easement (Doc. #2081799)
is also located within the Regional Park. The existing wetlands located along Spring Ditch are
shown on Sheets 1 and 2 of the Preliminary Plat as a wetlands boundary. The Spring Ditch or
any associated wetlands would not be altered in any way with the construction of this
development.
38.220.060. A.2 Floodplains. The portion of the Spring Ditch 100-year floodplain is located
within the Common Area Lot 1 (Lot CA-1) for the stormwater detention pond within of this
subdivision. Code Provision No. 6 would require the pond to be designed and built to assure
that it would not erode during a 100-year flood event.
38.220.060. A.3. Groundwater. Groundwater is known to be high in this area. The Applicant
provided GWIC monitoring wells to establish seasonal minimum and maximum groundwater
depths. Code Provision No. 3b prohibits lot owners from building basements and crawl spaces
due to high groundwater unless a certified engineer assures the City that no damage to
structures would occur.
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 25 of 44
38.220.060. A.4. Geology, Soils and Slopes. Geology and soils will likely be similar to those
encountered during the construction of Phases 4G & 4H of the Crossing 2 at Baxter Meadows
subdivision to the east of the Site. There are no known geologic hazards associated with this
property other than the regional designation of Seismic Zone 3. Conformance to relevant
building codes can mitigate this degree of potential hazard. No unusual construction
techniques are required due to geology, slopes, or soil types other than appropriate seismic
design standards common throughout the Gallatin Valley. Significant slopes are not
anticipated. The NRCS soils report was included with this preliminary plat submittal.
Wetlands near Spring Ditch have been delineated and its lines are shown on the Preliminary
Plat and would be shown on the final plat.
38.220.060. A.5. Vegetation. The property has been vacant for several years and has not
been used agriculturally in the recent past. The property is adjacent to the Gallatin County
Regional Park to the west, the Bozeman Fire Station No. 3 to the south, and residential
development on all other sides. No known critical plant communities have been located on
the property. After development, the majority of vegetation will be lawn, shrubs, and
boulevard trees typical of residential subdivisions. Per Code Provision No. 4, an approved
weed management plan must be provided with the final plat submittal and recorded prior to
approval of the final plat and the subdivision CC&R document must clarify that the HOA is
responsible for implementing and enforcing the weed management plan.
38.220.060. A.6. Wildlife. No animals listed under the “Animal Species of Special Concern”,
(Montana Natural Heritage Program, Helena, 2003) have been observed or are known to
occupy the property. Habitat most suitable for wildlife includes the area around the Spring
Ditch that will not be developed.
38.220.060. A.7. Agriculture. Due to development in the area, no agricultural practices have
been performed on the property for several years.
38.220.060. A.8 Agricultural Water User Facilities. The Spring Ditch agricultural facility
will continue to flow and the existing irrigation easement located completely within the
County Regional Park would not be abandoned or altered with this project.
38.220.060. A.9. Water and Sewer. Per the Engineering Report for this subdivision, water
and wastewater improvements would be designed to meet City standards and, with the
recommended conditions of approval and code provisions, this subdivision would not
significantly burden City water or sanitary sewer infrastructure.
38.220.060. A.10. Stormwater Management. The subdivision would not significantly
impact stormwater infrastructure. The stormwater systems would be designed to meet City
standards and would be maintained by the Park View Crossing HOA [see Conditions of
Approval No. 8 and 7 (k)].
38.220.060. A.11. Streets, Roads and Alleys. The subdivision would not significantly
impact the City’s street infrastructure. A single “loop” road called Stokes Lane would serve
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 26 of 44
the subdivision accessed from Vaquero Parkway and an extension of Tschache Lane into the
subdivision from the intersection with Vaquero Parkway.
The new Stokes Lane loop road would have the following characteristics:
- 60-foot right-of-way
- 33 feet from back of curb to back of curb
- Standard City of Bozeman curb and applicable curb returns with the exception of a sidewalk
along the western side of Stokes Lane which would be substituted by an existing shared-use
path/trail within the County Regional Park along this same alignment.
A new privately maintained alley ROW bisects the subdivision in a north/south orientation
and would have the following characteristics:
- 30-foot public access easement
- 16-foot paved width
- Inverse crown (without curb and gutter).
This subdivision is not expected to adversely affect existing public land access. Access to the
public lands of the County Regional Park and Dinosaur Park currently exist on Oak Street and
at the Bozeman’s Firehouse No. 3. Furthermore, the Applicant would install a paved 10-foot
wide shared-use pathway on the western side of Vaquero Parkway to provide trail/park
connectivity for the community. This shared-use path would connect to and through the
subdivision via Open Space Lots 1 and 2 and a short stub pathway on the west side of Stokes
Lane to the 97-acre Gallatin County Regional Park property line.
38.220.060. A.12. Non-Municipal Utilities. This subdivision would not significantly impact
non-municipal utilities. Standard 10-ft utility easements would be provided across all lots. All
private utilities are available in the area to serve this subdivision.
38.220.060. A.13. Land Use. This subdivision is consistent with residential land uses
allowed by the underlying R-3, Medium-density Residential zoning; specifically, the
development of duplex, triplex and fourplex dwelling units are principal permitted uses
within the R-3 district. The R-3 district requires a minimum density of 5 dwelling units per
net -acre. The net -acreage of this 7-acre property excludes 2.93-acres of unbuildable lands of
streets, open space lots and the stormwater common area lot. This 4.07 net-acre, 44-
residential lot subdivision would more than double the minimum required density of 20
dwelling units. The townhome lots are allowed at 3,000 square feet (sf) per dwelling unit lot
and the duplex lot is allowed at 2,500 sf per lot. The 4.07-net-acre, 44 dwelling unit
subdivision provides 74 percent of the maximum density allowed in the R-3 zone for
townhome dwelling units. The maximum density for this 4.07-acre subdivision would be 59
townhomes or 71 duplex dwelling units, depending on what type of residential structure is
built.
The proposed residential use would not adversely affect adjacent land uses in the area.
Existing land uses bordering the east and north sides of the Park View Crossing property are
residential, predominantly single-household detached dwelling units with some apartment
buildings. The properties bordering the south and west are part of a Gallatin County Regional
Park and are in public use, including a Fire Department Station and trail heads for the park.
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 27 of 44
The subdivision must provide a sidewalk and two open space lots which link Vaquero
Parkway ROW to a new shared-use path/trail within the County Regional Park to the west.
Two Open Space Lots, OS-1 and OS-2, serve as mid-block crossings for pedestrian and
bicyclist and equate to 0.05-acres or 0.71% of the total area. One 0.29-acre lot serves as a
Common Area Lot 1 stormwater drainage pond representing 4.14% of the land area. The
streets equate to 2.59.64-acres or 37% of the total area. The residential lots total 4.07 net-
acres and represent 58.14% of the 7-acre property.
Access to the abutting County Regional Park would be enhanced by the development via
sidewalks, the east-west mid-block open space lots extending pedestrian and bicycle access
from Vaquero Parkway to the park property line. Both open space lots within the subdivision
would be open to the public and easily accessible and would be landscaped and provided with
trees and a minimum 5-foot wide sidewalk.
No hazards or nuisances are expected to be created by the development. Safety issues related
to construction activity would be effectively controlled by City standards for construction
management practices.
38.220.060. A.14. Parks and Recreation Facilities. The Applicant seeks to satisfy Parkland
requirements with a combination of cash-in-lieu and off-site trail corridor improvements. The
Applicant requests to provide cash-in-lieu of parkland because there is a publicly-accessible
97-acre Gallatin County Regional Park abutting the subdivision to the west. The Applicant
would provide a shared-use path along the subdivision’s eastern frontage, within the Vaquero
Parkway ROW, as part of this parkland in-lieu requirement. The Applicant is continuing
negotiations with the Parks Department to satisfy the parkland requirement of this
subdivision. Per Condition of Approval No. 2, those agreements would be finalized prior to
submittal of a final plat application.
38.220.060. A.15. Neighborhood Center Plan. Neighborhood centers are required for
subdivisions of 10-acres or more per 38.410.020. This subdivision is 7-acres and, therefore,
exempt from this requirement. However, the County Regional Park abuts the subdivision
along its western frontage.
38.220.060. A.16. Lighting Plan. The preliminary street lighting plan is in accordance with
the requirements of the BMC. Four street light fixtures are proposed with this development,
each light spacing and design would meet City of Bozeman Design Standards and
Specifications Policy. Per Code Provision No. 32, the Applicant is required to request the
formation of a special improvement lighting district (SILD) for the district property owners,
typically the HOA, to pay the costs of operation and maintenance of street light fixtures
associated with this subdivision.
38.220.060. A.17. Miscellaneous. Not applicable.
38.220.060. A.18. Affordable Housing. The Applicant does not propose the inclusion of
affordable housing meeting the provisions of BMC Section 38.380 and, due to the passage of
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 28 of 44
State law HB 259 by the 2021 State Legislature resulting in the provisions of MCA Section
76.3.514, the affordable housing provisions of 38.380.030 do not apply to this subdivision.
Montana Code Annotated (MCA) 2021, Title 76. Land Resources and Use.
1. Compliance with the survey requirements of Part 4, Section 76-3-402 of the
Montana Subdivision and Platting Act.
a. The Preliminary Plat has been prepared in accordance with the survey requirements of the
Montana Subdivision and Platting Act by a Professional Engineer registered in the State of
Montana. A Subdivision Exemption lot line adjustment with the County Regional Park lands
has been approved per Project No. 20312 but has not been recorded. This lot line adjustment
is a result of a “land swap” with Gallatin County to adjust access to the northern portions of
the park and the stormwater pond common area lot (CA-1) of this subdivision. Per Condition
of Approval No.4, the approved Subdivision Exemption lot line adjustment plat map must be
recorded with the Gallatin County Clerk and Recorder prior to approval of the final plat for
this subdivision.
Also outlined in Code Provision No. 1, the final plat must comply with State statute,
Administrative Rules of Montana, and the Bozeman Municipal Code (BMC). A Condition of
Approval sheet must be included with the final plat and updated with any additional required
notations as required by these Preliminary Plat conditions or code provisions.
2. Compliance with the local subdivision regulations as provided for in Part 5 of
the Montana Subdivision and Platting Act per BMC 38.240.130.A.5.e (1) Criteria, (b).
The final plat must comply with the standards identified and referenced in the BMC. The
Applicant is advised that unmet code provisions, or code provisions that are not specifically
listed as a condition of approval, does not, in any way, create a waiver or other relaxation of
the lawful requirements of the Bozeman Municipal Code or State law. Sections 3 and 4 of this
report identify conditions and code corrections necessary to meet all regulatory standards.
Staff recommends Conditions of Approval No. 1 through 6 and Code requirements 1 through
35 to address necessary documentation and compliance with adopted standards. Therefore,
upon satisfaction of all recommended conditions and applicable code corrections, the
subdivision would comply with local subdivision regulations.
3. The provision of easements to and within the subdivision for the location and
installation of any necessary utilities per BMC 38.410.060.
Code Provision Numbers 2 and 30 require that all easements, existing and proposed, must be
accurately depicted and addressed on the final plat and in the final plat application. Public
utilities must be located within dedicated street right of ways. Utility easements need to be
provided and granted with the final plat in accordance with public and private design
standards.

Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 29 of 44
4. The provision of legal and physical access to each parcel within the subdivision
per BMC 38.240.130.A.5.e (1) Criteria, (d).
Access to the property is from Vaquero Parkway which is a City-owned and maintained road.
Tschache Lane is being extended into the subdivision from Vaquero Parkway and would be a
City- owned and maintained road. The new loop road, Stokes Lane, would be dedicated to the
City for ownership and maintenance. An alley ROW would bisect the subdivision in a north-
south orientation and would be dedicated to the City although it is required to be privately-
maintained by the subdivision HOA per Code Provisions 3c and 11b.
5. Compliance with the local subdivision review procedures provided for in Part 6
of the Montana Subdivision and Platting Act.
The application was initially received on May 19, 2021 and was deemed inadequate for
further review. Revised application materials were received on June 30, August 25, and
November 19, 2021. The City deemed the application adequate for review on November 19,
2021. A public hearing was held by the Community Development Board on December 20,
2021 and the City Commission hearing was held on January 25, 2022 after the Applicant
requested in writing a postponement from the originally-scheduled hearing for January 11,
2022.
The hearings before the Community Development Board and City Commission have been
properly noticed as required by the BMC. Based on the recommendation of the Development
Review Committee (DRC) and other applicable review agencies, as well as any public
testimony received on the matter, the Community Development Board, acting as the Planning
Board per 38.240.130.A.3.b, must forward a written recommendation to the City Commission
who will make the final decision on the Applicant’s request, per 38.240.130.A.5.c. The staff
report for the January 25, 2022 City Commission hearing presented the Community
Development Board’s written recommendation to the Commission on this application. That
recommendation was for conditional-approval with the staff-recommended conditions and
code provisions.
The final decision for a Major Subdivision Preliminary Plat with less than 50 lots must be
made within 60 working days of the date it was deemed adequate (November 19, 2021).
Pursuant to BMC 38.240.130.A.5.a.4, the City Commission shall approve, conditionally
approve or deny the subdivision application by January 19, 2021 unless there is a written
extension from the developer, not to exceed one year. The Applicant requested a continuance
of the City Commission’s consideration of this application to the January 25, 2021 meeting
due to a previously unforeseen conflict with the Commission’s scheduling of cases on that
date.
Public notice for this application was given as described in Appendix B beginning on
December 3, 2021 and ending on December 16, 2021. As of the date of this report, there were
two public comments received; both after this public notice period. They are:
(1.) During the public comment period of the December 20, 2021 Community Development
Board meeting, a neighbor called in to express concern with (1) potential double-parking by
park visitors along Vaquero Parkway; (2) concern with increased traffic congestion on
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 30 of 44
Vaquero Parkway due to the proposed development; and (3) objection to the sidewalk
variance request due to lack of “undue hardship” to the Applicant who wants to avoid the cost
of installing the concrete sidewalk.
The Community Development Board proceedings may be viewed here under the date
December 20, 2021: https://www.bozeman.net/services/city-tv-and-streaming-audio
(2.) On December 22, 2021, another neighbor of the Site called our office to express concern
that the increased number of residents of the subdivision would negatively affect a flock of
partridge birds whose habitat includes the Site and the neighboring park. She asked if an
environmental impact study had been conducted to identify the impact to these birds and
their habitat. She stated that neighbors of the area delight in seeing the flock of partridges
wander about the area. Staff explained that Montana subdivision law requires Applicants to
provide information about wildlife and habitat that may be affected by the subdivision and
this information was provided and can be found in the Community Development Board staff
report which was sent to her. In response, staff researched the Montana Natural Heritage
Species of Concern and Potential Species of Concern lists and the partridge species of birds is
not listed therein [Please see 38.220.060.A.6, Wildlife subsection on page 26 of this report].
On December 27, 2021, the staff report for this Park View Crossing Major Subdivision
Preliminary Plat application was completed and forwarded with a recommendation for
consideration by the City Commission. Based on the recommendation of the DRC and other
applicable review agencies, as well as any public testimony received on the matter, the
Community Development Board forwarded their written recommendation via that staff
report to the City Commission who made the final decision on the application on January 25,
2022.
8. Compliance with Chapter 38 of the Bozeman Municipal Code (BMC) and other
relevant regulations.
a. The final plat must comply with the standards identified and referenced in the BMC. The
Applicant is advised in Code Provision No. 1 that unmet code provisions, or code provisions
that are not specifically listed as a condition of approval, does not, in any way, create a waiver
or other relaxation of the lawful requirements of the Bozeman Municipal Code or State law.
b. Sections 3 and 4 of this report identify staff-recommended conditions of approval and
applicable code corrections necessary to meet all regulatory standards. It is expected that
upon satisfaction of all 6 conditions of approval and 35 code provisions, the subdivision
would comply with local subdivision regulations, meeting this criterion.

Primary Subdivision Review Criteria, Montana Code Annotated (MCA)
Section 76-3-608. Criteria for local government review.
(1) The basis for the governing body's decision to approve, conditionally approve, or deny
a proposed subdivision is whether the subdivision application, preliminary plat, applicable
environmental assessment, public hearing, planning board recommendations, or additional
information demonstrates that development of the proposed subdivision meets the
requirements of this chapter. A governing body may not deny approval of a proposed
subdivision based solely on the subdivision's impacts on educational services or based solely
on parcels within the subdivision having been designated as wildland-urban interface parcels
under 76-13-145.
Staff Comment: The proposed preliminary plat, when satisfying the 6 conditions of
approval and 35 code provisions, would meet the requirements of MCA 76-3-608. It is
expected that the nearby Meadowlark and Emily Dickinson Elementary Schools, the Chief
Joseph Middle School and the Gallatin High School would serve students residing in the
proposed subdivision with no adverse impacts to capacity. The Site is not designated a
wildland-urban interface parcel.
(2) The governing body shall issue written findings of fact that weigh the criteria in
subsection (3), as applicable.
Staff Comment: Section 7 of this report, found on pages 36 to 38, represent these Findings of
Fact and Order.
(3) A subdivision proposal must undergo review for the following primary criteria:
(a) except when the governing body has established an exemption pursuant to
subsection (6) or except as provided in 76-3-509, 76-3-609(2) or (4), or 76-3-616, the
specific, documentable, and clearly defined impact on agriculture, agricultural water user
facilities, local services, the natural environment, wildlife, wildlife habitat, and public health
and safety, excluding any consideration of whether the proposed subdivision will result in a
loss of agricultural soils;
(b) compliance with:
(i) the survey requirements provided for in part 4 of this chapter;
(ii) the local subdivision regulations provided for in part 5 of this chapter; and
(iii) the local subdivision review procedure provided for in this part;
(c) the provision of easements within and to the proposed subdivision for the location
and installation of any planned utilities; and
(d) the provision of legal and physical access to each parcel within the proposed
subdivision and the required notation of that access on the applicable plat and any instrument
of transfer concerning the parcel.
Staff Comment: Compliance with these elements and criteria are discussed on pages 25
through 28.

Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 32 of 44
(4) The governing body may require the subdivider to design the proposed subdivision
to reasonably minimize potentially significant adverse impacts identified through the review
required under subsection (3) but may not require a set-aside of land or monetary
contribution for the loss of agricultural soils. Pursuant to 76-3-620, the governing body shall
issue written findings to justify the reasonable mitigation required under this subsection (4).
Staff Comment: The subject property has lain fallow for several years and is no longer in
agricultural use and, therefore, there are no adverse impacts to agricultural soils as a result
of residential development of the Site.
(5) (a) In reviewing a proposed subdivision under subsection (3) and when requiring
mitigation under subsection (4), a governing body may not unreasonably restrict a
landowner's ability to develop land, but it is recognized that in some instances the impacts of
a proposed development may be deemed unmitigable and will preclude approval of the
subdivision.
Staff Comment: The six conditions of approval placed on this preliminary plat will not restrict
the owner’s development of the Site.
(b) When requiring mitigation under subsection (4) and consistent with 76-3-620, a
governing body shall consult with the subdivider and shall give due weight and consideration
to the expressed preference of the subdivider.
Staff Comment: Under subsection 4 above, there is no loss of agricultural soils and, therefore,
no mitigation required.
(6) A governing body may conditionally approve or deny a proposed subdivision as a
result of the water and sanitation information provided pursuant to 76-3-622 or public
comment received pursuant to 76-3-604 on the information provided pursuant to 76-3-
622 only if the conditional approval or denial is based on existing subdivision, zoning, or
other regulations that the governing body has the authority to enforce.
Staff Comment: As noted on page 26, water and sanitary sewer service would be provided to
the subdivision by the City of Bozeman and this service would not significantly burden City
water or sanitary sewer infrastructure.
(7) A governing body may not require as a condition of subdivision approval that a
property owner waive a right to protest the creation of a special improvement district or a
rural improvement district for capital improvement projects that does not identify the
specific capital improvements for which protest is being waived. A waiver of a right to protest
may not be valid for a time period longer than 20 years after the date that the final subdivision
plat is filed with the county clerk and recorder.
Staff Comment: The special improvement district (SID) waivers noted in Condition of
Approval No. 6, found on page 11, follow City of Bozeman Resolution 5076, Policy 1 and are
specifically pertinent to the development of this property and this subdivision.
(8) A governing body may not approve a proposed subdivision if any of the features and
improvements of the subdivision encroach onto adjoining private property in a manner that
is not otherwise provided for under chapter 4 or this chapter or if the well isolation zone of
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 33 of 44
any proposed well to be drilled for the proposed subdivision encroaches onto adjoining
private property unless the owner of the private property authorizes the encroachment. For
the purposes of this section, "well isolation zone" has the meaning provided in 76-4-102.
Staff Comment: A small section of the existing Spring Ditch agricultural irrigation facility
is located near the northern boundary of this subdivision and encroaches into the northern
portion of the subdivision’s stormwater easement. The Spring Ditch would not be altered
with the development of this subdivision [see Surface Water discussion on page 25].
(9) If a federal or state governmental entity submits a written or oral comment or an
opinion regarding wildlife, wildlife habitat, or the natural environment relating to a
subdivision application for the purpose of assisting a governing body's review, the comment
or opinion may be included in the governing body's written statement under 76-3-620 only
if the comment or opinion provides scientific information or a published study that supports
the comment or opinion. A governmental entity that is or has been involved in an effort to
acquire or assist others in acquiring an interest in the real property identified in the
subdivision application shall disclose that the entity has been involved in that effort prior to
submitting a comment, an opinion, or information as provided in this subsection.
Staff Comment: No federal or state governmental entity has commented on this
subdivision proposal.
(10) Findings of fact by the governing body concerning whether the development of the
proposed subdivision meets the requirements of this chapter must be based on the record as
a whole. The governing body's findings of fact must be sustained unless they are arbitrary,
capricious, or unlawful.
Staff Comment: These findings are noted in Section 7 of this report on pages 36 to 38.

(3) The effect on local services.
Water/Sewer – Water and sewer systems exist to serve the subdivision. The Applicant
proposes to extend water and sewer mains to the subdivision. Code Provision No. 25 requires
the Applicant to submit plans for water and sewer main extensions, approved by the Montana
Department of Environmental Quality, to be reviewed by the City. Code Provision No. 2
requires a City standard sewer easement where the sewer system is located. Building permits
would not be issued prior to City acceptance of site infrastructure improvements, unless
concurrent construction is requested and conditions allow.
Water rights exist for the subject property. The Applicant proposes to transfer to City
ownership existing water rights as outlined in Code Provision No. 5.

Streets – The 2020 Bozeman Community Plan/Growth Policy and subdivision standards
require adequate connectivity of a development to the street grid. Access to the Site would be
taken from Vaquero Parkway, a designated local street. A new Stokes Lane would provide
access from Vaquero Parkway along with a westward extension of Tschache Lane into the
subdivision. An internal north-south alley bisecting the subdivision would be a publicly-
accessible yet privately-maintained alley as outlined in Code Provision No. 3g.
BMC 38.400.080, Sidewalks adjacent to public lands. This requires a sidewalk along the
western side of the new Stokes Lane as it abuts a public park. Condition of Approval No. 3
requires the final plat to show a City-standard sidewalk meeting this code provision. This BMC
standard and Condition of Approval No. 1 would implement the City Community Plan/Growth
Policy N-1.8 which states: “Install, replace and maintain missing or damaged sidewalks, trails
and shared use paths.”
Walkability, Transit and Bikeability. This subdivision provides a sidewalk along the extension
of Tschache Lane, along Stokes Lane, and provides a mid-block crossing pathway within the
open space Lots OS-1 and OS-2. Not shown on Sheet 2 of the Preliminary Plat, but required by
Condition of Approval No. 3, is a City-standard sidewalk along the west side of Stokes Lane,
as required by the following BMC standards.
Sec. 38.400.050. - Street and road right-of-way width and construction standards.
A. All streets and roads providing access to, and within, the proposed development must meet
the following standards:
1. Right-of-way width and construction standards contained in this chapter: the most recently
adopted long range transportation plan; the City of Bozeman Design Standards and
Specifications Policy; and the City of Bozeman Modifications to Montana Public Works
Standard Specifications.
Stokes Lane must meet the local street section and include sidewalk, boulevard, and street
trees on both sides of the street.
Sec. 38.400.080.B – Sidewalks adjacent to public lands. The developer must install sidewalks
adjacent to public lands, including, but not limited to, parks, open space, and the intersection
of alleys and streets or street easements. Applicable sidewalks and development frontages
adjacent to public lands are subject to the provisions of section 38.510.030.I. Therefore, a 6-
foot wide sidewalk is required on the west side of Stokes Lane per Condition of Approval No.
3.
The Community Plan/growth policy encourages development to be walkable, which is
defined in the Plan’s Appendix F Glossary as: Walkable. A walkable area has:
• A center, whether it’s a main street or a public space.
• People: Enough people for businesses to flourish and for public transit to run frequently.
• Parks and public space: Functional and pleasant public places to gather and play.
• Pedestrian design: Buildings are close to the street, parking lots are relegated to the back.
• Schools and workplaces: Close enough that walking to and from home to these destinations is
realistic.
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 35 of 44
• Complete streets: Streets designed for bicyclists, pedestrians, and transit.
With the complexity of features needed to create a walkable environment, no one Site is likely
to provide all the needed elements. The additional density of the proposed subdivision in this
area is expected to help provide for element two above--to support public transit in in the
area.
Looking at the private, proprietary algorithm of WalkScore.com, the Site was given a Walk
Score of 21 out of 100 which denotes that the Site and area are car-dependent. It has a Transit
score of 19, which denotes minimal transit service, and a Bike Score of 41, which denotes that
the area is “somewhat bikeable” according to the WalkScore.com algorithms.
However, this algorithm walk, transit and bike score may not know the local assets in the area
and there is no contact information on the website for staff to inquire as to how recent their
data is for this area, or for the City.
There is a Streamline “Brown line” bus stop at Oak at the County Regional Park.
There are bicycle lanes surrounding the area on Davis Lane, Oak Street, Baxter Lane and
Ferguson Avenue. A north-south bike route is located one block east on Hunters Way.
The 2017 Bozeman Transportation Master Plan shows a recommended $250,000 bike path
improvement (SP-16) which would extend bike travel lanes or a shared use path along
Tschache Lane from Davis Lane west to N. 27th Avenue linking to other north-south facilities.
There would be a shared use path along Vaquero Parkway installed by the Applicant and there
are nearby shared use paths along Oak Street and Ferguson Avenue.
Average walk score for the City as a whole was given a 48 out of 100. Again, these values are
provided by Walk Score, a private organization which presents information on real estate and
transportation through walkscore.com. A score is not an indication of safety or continuity of
services or routes. Scores are influenced by proximity of housing, transit, trails, commerce
and services and expected ability, as determined by the algorithm, to meet basic needs
without using a car. There are no adopted BMC development standards relating to the walk
score.
A traffic impact summary was provided with the application and it found that the
infrastructure that exists and is proposed for the project would adequately service the
development and no upgrades were proposed for any nearby intersections.
Police/Fire – The area of the subdivision is within the service area of both these departments.
No concerns regarding service availability have been identified.
Stormwater - The subdivision must construct storm water management and water quality
facilities conforming to standards of the Bozeman Municipal Code. The maintenance of the
stormwater facilities are the responsibility of the Home Owners’ Association (HOA) as
outlined in Code Provisions Numbers 3a and 6. Inspection of installed facilities prior to final
plat will verify that standards have been met.

Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 36 of 44
Parklands – The Applicant has asked to provide both cash-in-lieu and improvements-in-lieu
contributions in-lieu of providing parkland within the subdivision as required by BMC 38.420.
Per conversations with the City of Bozeman Parks and Recreation Department (PARKS), a 10-
foot wide paved shared-use pathway would be installed by the Applicant within the Vaquero
Parkway right of way (ROW), located immediately east of the platted subdivision area, and
would extend from the property’s northern boundary to the southern boundary. As part of
this Improvements-in-lieu agreement, the shared use path may be further installed by the
Applicant from Baxter Lane to Davis Lane. This has been discussed by PARKS as the ideal
location for a shared-use pathway providing connectivity and access to the County Regional
Park abutting the subdivision to the west through (1) the sidewalks within the subdivision;
(2) through the mid-block crossing Open Space Lots OS-1 and OS-2; (3) to a stub-out concrete
pad at the park’s eastern boundary on the same plane/alignment as the OS lots.
This offer would be part of a combined cash- and improvements-in-lieu to satisfy their
parkland requirement for the 44 new dwelling units. As the coordination of parkland
contributions is ongoing with PARKS, the shared use path surfacing and exact locations and
extents of the path improvements have yet to be finalized and, per Condition of Approval No.
2, details of this path must be finalized and submitted for City review and approval with the
final plat application.
(4) The effect on the natural environment.
No significant negative impacts to the natural environment have been identified. The
stormwater pond of Lot CA-1 at the northern end of the subdivision would be designed to
ensure that stormwater would not adversely affect the Spring Ditch irrigation ditch and
associated flora and fauna thereon.
The Site is in a potential area of high groundwater which may negatively impact future
structures or cause illicit discharges into the sanitary sewer and over burden the surface
drainage system. Code Provision No. 3b prohibits crawl spaces or basement without first
consulting a professional engineer certified in the State of Montana who would certify that
groundwater would not harm these structures. This requirement will protect both future
structure owners from future hazards of flooding and lessen burdens on the public from illicit
discharges.
BMC 38.550.070, Landscaping of public lands. This requires use of wells or surface water
rights to irrigate right-of-way boulevard greens, parks and open spaces rather than municipal
water supply.
(5) The effect on wildlife and wildlife habitat.
No animals listed under the “Animal Species of Special Concern”, (Montana Natural Heritage
Program, Helena, 2003) have been observed or are known to occupy the property. Habitat
most suitable for wildlife includes the area around the Spring Ditch that will not be developed.

(6) The effect on public health and safety.
With the recommended conditions of approval and required plat corrections, the subdivision
is not expected to adversely impact public health and safety. The intent of the regulations in
Chapter 38 of the Bozeman Municipal Code (BMC) is to protect the public health, safety and
general welfare. The subdivision has been reviewed by the DRC which has determined that it
is in general compliance with the BMC standards with recommended conditions and code
provisions. Conditions deemed necessary to ensure compliance have been noted throughout
this staff report. Code Provision No. 1 requires full compliance with all applicable State and
BMC code requirements.
All subdivisions must be reviewed against the criteria listed in 76-3-608.3.b-d, Montana Code
Annotated (MCA) and as a result, the Department of Community Development has reviewed
this application against the listed criteria and further provides the following summary from
Applicant submittal materials and code requirements. It is noted that all infrastructure would
meet City standards.
SECTION 7 – FINDINGS OF FACT, ORDER, AND APPEAL PROVISIONS
A. PURSUANT to Chapter 38, Article 2, BMC, and other applicable sections of Chapter 38,
BMC, public notice was given, opportunity to submit comment was provided to
affected parties, and a review of the preliminary plat described in these findings of fact
was conducted.
B. The purposes of the preliminary plat review were to consider all relevant evidence
relating to public health, safety, welfare, and the other purposes of Chapter 38, BMC;
to evaluate the proposal against the criteria and standards of Chapter 38 BMC, BMC;
and to determine whether the plat should be approved, conditionally approved, or
denied.
C. The matter of the preliminary plat application was considered by the City Commission
at a public hearing on January 25, 2022 at which time the Department of Community
Development Staff reviewed the project, submitted and summarized the conditions of
approval, clarified unresolved issues and summarized the public comment submitted
to the City prior to the public hearing.
D. The owner and Applicant of this preliminary plat, Campeche Shores Development
Company, LLC. Is represented by Hyalite Engineering and Mr. Brett Megaard who, on
behalf of the owner/applicant, acknowledged understanding and agreement with the
recommended conditions of approval and code provisions.
E. The City Commission requested public comment at the public hearing on January 25,
2022 and no members of the public offered testimony on the proposed subdivision.
F. It appeared to the City Commission that all parties and the public wishing to examine
the proposed preliminary plat and offer comment were given the opportunity to do so.
After receiving the recommendation of the relevant advisory bodies established by
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 38 of 44
Section Chapter 38, BMC, and considering all matters of record presented with the
application and during the public comment period defined by Chapter 38, BMC, the
City Commission has found that the proposed preliminary plat would comply with the
requirements of the Bozeman Municipal Code if certain conditions were imposed.
Therefore, being fully advised of all matters having come before her regarding this
application, the City Commission makes the following decision.
G. The preliminary plat has been found to meet the criteria of Chapter 38, BMC, and is
therefore approved, subject to the conditions listed in Section 3 of this report and the
correction of any elements not in conformance with the standards of the Chapter
including those identified in Section 4 of this report. The evidence contained in the
submittal materials, advisory body review, public testimony, and this report, justify
the conditions imposed on this development to ensure that the final site plan and
subsequent construction complies with all applicable regulations, and all applicable
criteria of Chapter 38, BMC.
H. This City Commission order may be appealed by bringing an action in the Eighteenth
District Court of Gallatin County, within 30 days after the adoption of this document
by the City Commission, by following the procedures of Section 76-3-625, MCA. The
preliminary approval of this single phased major subdivision shall be effective for two
(2) years from the date of the signed Findings of Fact and Order approval for this
single-phase subdivision. At the end of this period the City may, at the request of the
subdivider, grant an extension to its approval by the Community Development
Director for a period of mutually agreed upon time.

APPENDIX A –PROJECT SITE ZONING AND GROWTH POLICY
Project Site Zoning. The subject property is zoned R-3, Medium-density Residential District.
The property was annexed into the City in 2001 by Resolution No. 3487. Records indicating
when the property was given the R-3 zoning are unclear but by 2010, the Site was zoned R-3.
Figure 5: R-3 zoning for the subject property and PLI zoning for the County Park
The intent of the R-3 residential medium density district is to provide for the development of
one- to five-household residential structures near service facilities within the city. This
purpose is accomplished by:
1. Providing for minimum lot sizes in developed areas consistent with the established
development patterns while providing greater flexibility for clustering lots and mixing
housing types in newly developed areas.
2. Providing for a variety of housing types, including single household dwellings, two to four
household dwellings, and townhouses to serve the varied needs of households of different
size, age and character, while reducing the adverse effect of non-residential uses.
Use of this zone is appropriate for areas with good access to parks, community services
and/or transit.

Staff Findings: This subdivision is located next to a regional park. The Streamline Brown Line
bus route has a stop at the regional park along W. Oak Street. The Subdivision would provide
lots for duplex, triplex and fourplex townhome dwelling units offering a mix of lot sizes.
Adopted Growth Policy Designation: The Future Land Use Map of the Bozeman Community
Plan designates the subject property to develop as “Parks and Open Space Lands” (green color
on map). This is deemed a “Scribner’s error” or a mistake on our 2020 Community Plan land
use map, as the property is zoned R-3, Medium-density Residential and is surrounded by
lands designated the “Urban Neighborhood” land use category. The zoning designation of R-
3 District for this property confers to the owner the right to develop the land according to the
uses and standards allowed by that R-3 District. The zoning surpasses the land use
designation. When the Community Plan Future Land Use Map (FLUM) is next updated, this
error will be corrected to reflect the correct designation of “Urban Neighborhood” for this
Site.
Figure 6: 2020 Community Plan Future Land Use Map of Site
The Urban Neighborhood category (tan color on map) primarily includes “urban density
homes in a variety of types, shapes, sizes, and intensities. Large areas of any single type of
housing are discouraged. In limited instances, an area may develop at a lower gross density
due to site constraints and/or natural features such as floodplains or steep slopes.
Complementary uses such as parks, home-based occupations, fire stations, churches, schools,
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 42 of 44
and some neighborhood-serving commerce provide activity centers for community gathering
and services.” “Higher density residential areas are encouraged to be, but are not required or
restricted to, proximity to commercial mixed use areas to facilitate the provision of services
and employment opportunities without requiring the use of a car.”
Staff Findings: The proposed subdivision would provide a mix of lot sizes and a mix of housing
types which are consistent with the Urban Neighborhood land use category and the
Community Plan/growth policy goals and objectives. In particular, the mix of lot sizes and
housing types would provide the mix of housing in this generally single-household
neighborhood that addresses the objective that “Large areas of any single type of housing are
discouraged.”
Applicant’s Narrative. The following is a description by the Applicant as to the subdivision’s
compliance with applicable Community Plan policies and objectives.
“The Park View Crossing Subdivision has been carefully designed in conformance with the
Bozeman Community Plan 2020. As a planned residential community, it is consistent with the Plan
Themes and community-derived desired outcomes; specifically:
“Theme 2: A City of Unique Neighborhoods”
Goal N-1: Support well-planned, walkable neighborhoods.
Park View Crossing will provide residents easy access to the neighboring park, while also being
centrally located within the city and having multi-modal access to public transportation. A shared
use pathway will be constructed along the west side of Vaquero Parkway that will provide park
connection from the northern property boundary to the southern edge of the property. Sidewalks
will also be provided throughout the development.
Goal N-2: Pursue Simultaneous emergence of commercial nodes and residential development
through diverse mechanisms in appropriate locations.
The proposed subdivision will be the last of its kind in the vicinity, as it is surrounded by existing
residential development on three sides and the County Regional Park on its fourth.
Goal N-3: Promote a diverse supply of quality housing units.
The townhomes constructed with the development will range from 4-plex to duplex units with
individual lot sizes ranging from 7,600 sq. ft. to 2,800 sq. ft. This will provide residents with a
variety of home choices while retaining the affordability of the individual units.
Goal N-4: Continue to encourage Bozeman’s sense of place.
The neighborhood will be sought after as it will provide more multifamily housing near the widely
known and frequented County Park while maintaining close access to schools, off-leash facilities
for dog walking, and public transportation into the city. The property is well within the City of
Bozeman Limits, and planned for extension of water and wastewater infrastructure for
conveyance to the City. All interior subdivision roads will be paved and include concrete curb,
DocuSign Envelope ID: 7A2B7E6E-A4EF-43D2-B254-3B88BABD16E5
Park View Crossing Major Subdivision Preliminary Plat; 21158 Page 43 of 44
gutter and sidewalks (per City of Bozeman Standard Specifications). The interior alley will be paved
with an inverted crown.”
Staff Findings: The proposed subdivision would provide a mix of housing types and lot sizes
that would facilitate a mix of housing sizes and prices which could accommodate middle-
income households and could provide smaller dwellings for “starter families” and/or “empty
nest” households who could vacate older, larger homes elsewhere in the city which, in turn,
could accommodate larger families. This supports the following Community Plan policies:
N-1.1: “Promote housing diversity, including missing middle housing.”
N-1.11: “Enable a gradual and predictable increase in density in developed areas over time.”
N-3.7: “Support compact neighborhoods, small lot sizes, and small floor plans, especially
through mechanisms such as density bonuses.”
N-3.8: “Promote the development of “Missing Middle” housing (side by side or stacked duplex,
triplex, live-work, cottage housing, group living, rowhouses/townhouses, etc) as one of the
most critical components of affordable housing.”
APPENDIX B – NOTICING AND PUBLIC COMMENT
Notice was provided at least 15 and not more than 45 days prior to the Community
Development Board and City Commission public hearings. Pursuant to BMC 38.220.420,
notice was provided by posting the site, mailing by certified mail to the Applicant and adjacent
property owners and by first class mail to all other owners within 200 feet on December 2,
2021. The site was posted with a notice on December 2, 2021 and a legal advertisement was
published in the Bozeman Daily Chronicle on December 3rd and 17th, 2021. Content of the
notice contained all elements required by Article 38.220., BMC.
No written public comment has been received as of the writing of this staff report. A
commenter spoke at the December 20, 2021 Community Development Board public hearing.

Engineering Report – Park View Crossing Major Subdivision
Introduction April 2021 Page 1
Version 09/24/2021
1 Introduction
1.1 Purpose of Report
This report is intended to serve as the design document for the infrastructure improvements
associated with the construction of a 44-lot major subdivision. The proposed infrastructure has
been designed without accounting for future connections, as the property is bordered to the west
by the Gallatin County Regional Park.
1.2 Scope
Expansion of existing infrastructure (water and sewer mains) and storm water design elements
are within the scope of this report. All improvements analyzed in this report are within the property
with proposed connections to existing infrastructure. No off-site improvements are expected.
2 Location and Site Information
The property occupies 7.0 acres and is located on the northwestern side of Bozeman and is
bordered to the east by Vaquero Parkway, in the NE ¼ of Section 3, Township 2 South, Range 5
East, P.M.M., City of Bozeman, Gallatin County, MT. The existing zoning and the nearby
surrounding zoning is R-3. The property is within the service area for municipal water and sewer
from the City of Bozeman.

Engineering Report – Park View Crossing Major Subdivision
Land Use April 2021 Page 2
Version 09/24/2021
3 Land Use
3.1 Existing
The site is currently a vacant lot with two existing intersection tie-ins – one off of Vaquero Parkway
and the other a continuation of Tschache Lane. The majority of the site has been left undisturbed,
with parking for the Gallatin County Regional Park just to the south. Of the 7.0-acre property, 0.3
acres is an existing stormwater pond site that was used for the Crossings 2 at Baxter Meadows
Phases 4G & 4H.
3.2 Proposed
The proposed major subdivision will consist of 44 townhome lots: nine 4-plex units, two 3-plex
units and one duplex. A road will be constructed that connects to the intersection of Tschache
Lane and Vaquero Parkway and loops to the north to connect back into Vaquero Parkway. The
road will surround a majority of the property and will be bordered by the park to the west. All
centralized lots will be alley-loaded with water and sewer mains installed within the 30’ alley right-
of-way. The exterior lots will be serviced by the loop road. As mentioned previously, both water
and sewer mains will connect to existing stub-outs from the improvements associated with Phases
4G & 4H of the Crossings 2 at Baxter Meadows. The existing stormwater pond to the north will
be extended to account for the proposed development, with the proposed storm sewer network
also connecting to existing stub-outs from previous improvements (Phase 4G & 4H).
4 Water System
The proposed water system will tie into existing mains installed during the development of the
Crossing 2 at Baxter Meadows Phases 4G & 4H. The water system will be looped into the City of
Bozeman water system at two places along Vaquero Parkway. At each end of the exterior loop
road (north and south) the water main will continue past the proposed alley and each will end at
a fire hydrant near the N-S leg of the loop road. The water main will also be installed within the
provided alley right of way.
All new water mains will be 8” diameter, class 51 ductile iron pipe. Fire hydrant leads will be 6”
diameter ductile iron pipe as well. Type K copper water services will extend 8’ past the property
line and be ¾” in diameter.
4.1 Water Use Data
Average Daily Flow
44 residential lots at 2.5 persons/dwelling = 110 people
110 people at 170 gpd = 18,700 gpd (425 gpd/lot)
Peak Demand
Peaking factor = 2.3 (peaking factor per City of Bozeman Design Standards)
18,700 gpd (2.3) = 43,010 gpd
Total max day flow = 43,010 gpd / 1440 = 29.9 gpm instantaneously
Main Sizing
29.9 GPM (Max Day) + 2000 GPM (Fire Flow) = 2029.9 GPM
2029.9 GPM in 8” Water Main ≈ 14 ft/sec (adequate for fire flow)
Engineering Report – Park View Crossing Major Subdivision
Sewer System April 2021 Page 3
Version 09/24/2021
29.9 GPM = Negligible velocity within an 8” main
Note: The Integrated Water Resources Plan (2013) showed that the typical domestic water
usage in a City of Bozeman home was around 45 gpcd. The Bozeman Water Facility Plan
(updated 2017) noted that “The domestic use parameter is consistently lower than 70 gpcd
for the non-irrigation season”. With irrigation being accounted for in the next section, the
above calculations are conservative.
Irrigation Demand
Assume 1”/week for irrigation of turf areas
Assume 4-month irrigation season
Building Areas:
Nine 4-plex units = 9 (7820 sq. ft.) = 70,380 sq. ft.
Two 3-plex units = 2 (6800 sq. ft.) = 13,600 sq. ft.
One duplex unit = 4340 sq. ft.
Total = 88,320 sq. ft. = 2.03 acres
Above calculations include driveway and sidewalk for each unit.
Total developable lot area = 4.07 acres
Irrigated turf = 2.04 acres
1”/week (16 weeks) = 1.33 ft of irrigation over 2.04 acres
Total irrigation = 118,187 cu. ft. (7.48 gal/cu. ft.) = 884,040 gal./year
Over 120-day irrigation season, 15 hours of irrigation per day
884,040 gal./year (1 year/120 days) (1 day/15 hrs) (1 hr/60 min) = 8.2 gpm
At 8.2 gpm during the summer months
8.2 gpm (60 min/hr) (24 hr/day) = 11,808 gpd
Peak hour flow during the summer/irrigation season would be 38.1 gpm.
4.2 Fire Flow
Within the design report for The Crossing 2 at Baxter Meadows, the fire hydrants tested for the
fire protection plan were each at or above 2,000 GPM for available fire flow. As of April 12, 2021,
the City Water Department fire tested the nearby hydrants with the following information; FH#2389
had a static pressure of 90psi and a residual of 82psi and FH#3033 having a pitot pressure of
68psi while flowing approximately 1385 GPM. This results in an available fire flow of
approximately 4,460 GPM at 20 psi. See attached for the City’s fire flow documentation.
5 Sewer System
During construction of Phases 4G & 4H of the Crossing 2, an 8-inch sewer main stub was
extended from a manhole on Vaquero Parkway. This sewer main stub is located at the northern
loop road tie in for the proposed development. As this is the low point of the property, the entire
sanitary sewer network within Parkview Crossing will drain to this point, and connect to the
existing 8” sewer mains in Vaquero Parkway.

Version 09/24/2021
5.1 Design Flow Rates
The average daily flow calculated above is 18,700 gpd (13 gpm).
The peak hour flow calculated above is 38.1 gpm.
Including infiltration:
150 gallons/acre/day (7 acres) = 1050 gpd = 0.73 gpm
Peak hour flow (including infiltration) = 38.83 gpm
The proposed 8” gravity mains are capable of flowing 38.83 gpm at minimum slope (0.4%) with a
depth of only 1.9” (24% full). This capacity calculation was performed using a Manning’s friction
factor of 0.013. As mentioned previously, the gravity network will then discharge into the existing
8” network located in Vaquero Parkway.
All sewer main piping will have uniform slope between manholes. Sewer mains have been
designed at nearly the same slope as the road centerline grades. Individual sewer services will
be provided for each lot within the development. The 4” Schedule 40 PVC sewer services will be
extended 8 feet past the property line of each lot. A 4” gravity sewer service on a ¼”/foot grade is
capable of supporting flows from each single-family townhome.
6 Stormwater Network
This section provides a design basis and hydraulic calculations for sizing storm water facilities for
the Parkview Crossings Major Subdivision. The City of Bozeman Design Standards and
Specifications Policy and the Montana Post-Construction Storm Water BMP Design Guidance
Manual (Peterson, Savage, and Heisler 2017) were used as the primary guidelines for this
stormwater drainage design.
6.1 General Design
The proposed development will be a combination of roadway and residential lots. The loop road
that extends from the intersection of Tschache Lane and Vaquero Parkway will be paved with
curb and gutter. The alley that splits the interior lots will be paved with an inverse crown.
Stormwater runoff generated from the roadway and residential lots is designed to be collected by
the curb and gutter and then directed toward the storm drain inlets. The stormwater that is
collected by the paved alley will travel down the centerline and to the curb and gutter to the north.
The runoff will then move through the storm sewer system pipes to the detention pond. The
detention pond has been designed with an outlet structure to limit stormwater runoff from the
developed site to the pre-developed runoff rates.
6.2 Hydrologic Methodology
The rational method was used to determine peak runoff rates. The rational formula provides a
peak runoff rate which occurs at the time of concentration.
Q = CiA
Where C = Weighted C Factor
i= Storm Intensity (in/hr)
A = Area (acres)
Q = Runoff (cfs)
Engineering Report – Park View Crossing Major Subdivision
Stormwater Network April 2021 Page 5
Version 09/24/2021
The storm intensities were developed from the IDF curve found in Figure I-2 of the City of
Bozeman Design Standards and Specifications. Runoff coefficients for each basin were
calculated using a weighted percentile of impervious and pervious area. The coefficient used are
shown in the table below.
Table 1 - Runoff coefficients used.
RUNOFF COEFFICIENTS
Undisturbed 0.2
Impervious 0.9
Time of concentration was determined using the following equation:
Tc = 1.87(1.1-C)D1/2
S1/3
Where Tc = Time of Concentration, minutes
S= Slope of Basin, %
C= Runoff Coefficient
D= Length of Basin, ft
The modified rational method approach was used to compute runoff volume. This method can
be used for storm durations equal or greater than the time of concentration. This method assumes
the maximum runoff rate occurs at the time of concentration and continues to the end of the storm.
Maximum runoff rates for durations greater than the time of concentration are less than the peak
runoff rate because average storm intensities decrease as duration increases. The total runoff
volume is computed by multiplying the duration of the storm by the runoff rate. The SCS method,
as discussed below, was also used for further analysis of the initial rainfall volume (i.e. the runoff
treatment volume).
The method outlined in Appendix C of the City of Bozeman Design Standards and Specifications
was used to size the detention pond for the 10-yr flood control volume. Hydraflow Hydrographs
Extension for AutoCAD was also used to calculate this volume and develop a stage-storage graph
for the pond. The program gave a more conservative volume for the 10-year design storm so the
weir was sized using this program. The hydrology calculations and pond sizing spreadsheets can
be found in Appendix B.
6.3 Detention Basin
The City of Bozeman requires infiltration, evapotranspiration or capture for reuse of the runoff
generated from the first 0.5 inches of rainfall from a 24-hour storm. A common methodology for
estimating the volume of direct runoff from a drainage basin is the SCS method. This method
requires basic data similar to the Rational Method: drainage area, a runoff factor, time of
concentration, and rainfall. However, the SCS approach is more sophisticated in that it also
considers the time distribution of the rainfall and an infiltration rate that decreases during the
course of a storm. The SCS method takes into account the Initial Abstraction (Ia) which is all
losses before runoff begins. This includes surface depressions, water intercepted by vegetation,
Engineering Report – Park View Crossing Major Subdivision
Stormwater Network April 2021 Page 6
Version 09/24/2021
evapotranspiration and infiltration. Initial abstraction generally correlates with soil and cover
parameters. Through studies of many small watersheds, Ia was found to be approximated by the
following empirical equation:
Ia = 0.2 x S [eq. 2-2 TR-55]
Where S = (1000/CN) – 10 [eq. 2-4 TR-55]
According to USDA’s Urban Hydrology for Small Watersheds, the Curve Number associated with
soil type B and 1/8 acre residential lots is 85 (Table 2-2a). Using the standard SCS method,
S = (1000/85) – 10 = 1.8 inches
Ia = 0.2 * 1.8 inches = 0.4 inches
Using a 10-year 24-hour rain event in the City of Bozeman the total precipitation (P) is 1.88 inches
of which 0.4 inches is lost due to initial abstraction according to USDA’s SCS method. Therefore,
this drainage plan includes provision for the first 0.4 inches of rainfall from the 24-hour storm to
be retained in surface depressions, intercepted by vegetation, or evapotranspired or infiltrated.
The remaining 0.1 inches required to be captured is accounted for by setting the weir elevation in
the detention pond 4 inches above the bottom of the pond. This allows the remainder of the first
0.5 inches of rainfall after initial abstraction to be retained (approximately 1944 cubic feet of
storage).
Pond 5B was designed to be oversized with the improvements for Phases 4G & 4H to account
for future development along Vaquero Parkway. However, the exact use of the future
development was not known at that time. The density of the proposed property is higher than
previously accounted for; thus, the pond will be extended and larger volume provided. As the
existing calculations still remain true for Pond 5B (outlet structure, weir, outlet pipe) the
calculations will be expanded on and updated to reflect the larger volume. The pond is designed
with an outlet structure to limit stormwater runoff from the developed site to the pre-developed
runoff rates for the 10-year storm and to not overtop during the 100-year storm. The outlet
structure for the pond will be re-located, but the outfall location will remain the same.
The original stormwater design (Phases 4G & 4H) accounted for a basin area of 9.48 acres to
determine the pre-development flow rate that would be controlled by the outlet structure. This
differs from the current 10.71 acre basin area that is proposed. Considering the increase in basin
area from the original to the current design and the fact that the outlet structure will not be altered,
the detention release rate will be less than the pre-development rate for the larger basin.
The method outlined in Appendix C of the City of Bozeman Design Standards and Specifications
was used to size the detention pond for the 10-year flood control volume. This method assumes
the outlet structure release rate is always equivalent to the pre-development runoff rate, and thus
provides a good starting point for overall pond volume. Hydraflow Hydrographs Extension for
AutoCAD was also used to calculate the pond volume and develop a stage-discharge graph for
the outlet structure. The stage-discharge graph better represents the changing weir flowrate that
will occur with the varying water surface elevations in the pond. Per the report generated from the
Hydraflow Extension, the weir flow rate will equal the pre-development flow rate at a pond depth
of approximately 18 inches (the top of the rectangular weir).
Engineering Report – Park View Crossing Major Subdivision
Stormwater Network April 2021 Page 7
Version 09/24/2021
In the event of a 100-year storm there is an emergency spillway that will prevent the pond from
over topping. This spillway will be lined with riprap to prevent erosion and will outlet directly into
the respective outlet ditch.
6.4 Inlets & Storm Sewer
Using the Modified Rational Method, a contributing flow to each inlet in the system was
determined. The inlet grates were designed to accommodate the 25-year storm event without
overtopping a depth 0.15’ below the top of curb or spreading greater than 9 feet. Inlets at sag
points were modeled using 50% clogging. Inlets and manholes will have a 9” sump for sediment
collection.
Storm pipes were sized to accommodate the 100-year storm event and were modeled in Storm
and Sanitary Analysis. Pipes are sloped to maintain a minimum velocity of 3 ft/s when flowing full
to prevent sediment deposit. The Hydraulic Grade line was plotted throughout the system and
pipes were sized to keep the HGL within the pipe during the 25 yr storm and 100 yr storm. A
manning’s N of 0.009 was used for the A-2000 Storm pipe within the model per the manufacturer’s
specifications.
6.5 Groundwater
Groundwater is known to be high in this area. A geotechnical report was done in 2001 that
included borings near the pond location. ST-29 near Pond 5B showed depth to groundwater at 3
feet below existing ground. Due to the high groundwater the maximum pond excavation depth for
Pond 5B is 2 feet. The depth of the existing Pond 5B will not change, only the overall area of the
pond will increase. This is reinforced as GWIC well #226772 is located near the southern parkling
lot in the Regional Park, and has its groundwater monitored over the last 15 years. Below is a
snippet of the groundwater elevation, showing that the highest value was 5.1 ft deep in 2009, but
in the last 5 years, the highest seen is approximately 5.6 ft deep.
6.6 System Maintenance
Regular maintenance of stormwater facilities is necessary for proper function of the drainage
system. In general, regular mowing of detention pond areas and removal of debris from the outlet
structure will be required to maintain functionality of the system. Sediment removal from the pond
may be required over time to restore the detention pond volume. Additional maintenance items
include removing debris from inlet grates and culverts, cleaning and flushing pipes, cleaning
manhole sumps, and establishing ground cover after construction. The detention pond will be
maintained by the HOA.
Engineering Report – Park View Crossing Major Subdivision
Stormwater Network April 2021 Page 8
Version 09/24/2021
6.7 Erosion Sediment Control
During construction, stormwater pollutant controls will include silt fencing, straw wattles, rock
check dams, and straw bales. Silt fence, straw waddles, or other perimeter protection will be
installed on the down gradient edge of disturbed soil. Straw wattles, straw bales, or other erosion
protection will be placed near existing and newly installed culverts. Temporary erosion control
measures will be installed and continuously maintained for the duration of construction.
This project will require acceptance of a Stormwater Pollution Prevention Plan (SWPPP) permit
for stormwater discharge associated with construction activity prior to starting any construction.
Protection during and immediately after construction, will be controlled in accordance with this
permit and the Montana Sediment and Erosion Control Manual.
Permanent erosion control will consist of implementation of seeding disturbed areas and placing
riprap at pond inlet/outlets. Any visible sediment must be removed from the stormwater system
prior to completing construction.
6.8 Flooding
Excessive runoff from a large storm event (significantly exceeding the design storm, i.e 100-year)
will be routed such that it does not inundate buildings, drainfields or over top the roadway. The
stormwater infrastructure including ditches, culverts, and detention pond outlet structures have
been analyzed for the 100-year storm. Stormwater that overtops the ponds during a large rain
event will flow through the emergency overflow and outlet to the respective ditches.
As noted in the original 2007 Spring Ditch Flood Study, no additional analysis is necessary for the
Spring Ditch as there is no longer a tie to the Section Line ditch and only continues to collect
groundwater though a series of drain pipes installed along Oak Street. With the Spring Ditch now
being surrounded by roads, and with no connection to a watershed, confirms that no new flood
hazard evaluation is necessary and the previous delineation is still accurate. Even more so now,
there is less hazard with the Spring Ditch than was previously noted in the report.

The Crossing 2 at Baxter Meadows Subdivision – Phase 4G & 4H
Stormwater Report
Bozeman, MT
Introduction
This report provides a design basis and hydraulic calculations for sizing stormwater
infrastructure for The Crossing 2 at Baxter Meadows Subdivision – Phase 4G & 4H. The
project in total is 5.8 acres of residential development and is located between the
intersection of Vaquero Parkway and Baxter Lane to Vaquero Parkway and Davis Lane.
Phases 4A through 4F of The Crossing have already been constructed. Stormwater
calculations for the entire project (including phase 4G and 4H) were submitted in The
Engineering Design Report for The Crossing at Baxter Meadows (March 2013).
Generally the stormwater system and calculations have stayed consistent with what was
originally submitted, but this report provides updated and additional information including
inlet calculations, culvert capacity calculations and pond sizing. Much of this report will
reference the Engineering Design Report for The Crossing at Baxter Meadows (March
2013).
The City of Bozeman Design Standards and Specifications (March 2004) was used as
the primary guideline for this stormwater drainage design along with The 2002 Edition of
the Circular 8 of Montana Department of Environmental Quality (MDEQ).
General Design
Phase 4G and 4H will be a combination of roadway and residential lots. Vaquero
Parkway has been designed with curb and gutter as originally designed in 2013.
Stormwater runoff generated from the roadway and residential lots is designed to be
collected by the curb and gutter and then directed toward the storm drain inlets. The
runoff will then move through the storm sewer system pipes to the detention ponds. The
detention ponds have been designed with outlet structures to limit stormwater runoff
from the developed site to the pre-developed runoff rates.
Inlets & Storm Sewer
Using the Modified Rational Method, a contributing flow to each inlet in the system was
determined. The inlet grates were designed to accommodate the 25-year storm event
without overtopping a depth 0.15’ below the top of curb or spreading greater than 9 feet.
Inlets at sag points were modeled using 50% clogging. Inlets and manholes will have a
9” sump for sediment collection.
To avoid crossing Spring Ditch with the storm sewer, the two northern more inlets (SDI-
100 and SDI-101) were moved south from their original 2013 design location. This
change created a larger drainage area that flows north to Existing Pond 7. The additional
flowrate and volume was modeled to verify that Pond 7 could handle the added area
without exceeding the pre-development flow rate.
Storm pipes were sized to accommodate the 100-year storm event and were modeled in
Storm and Sanitary Analysis. Pipes are sloped to maintain a minimum velocity of 3 ft/s
when flowing full to prevent sediment deposit. The Hydraulic Grade line was plotted
throughout the system and pipes were sized to keep the HGL within the pipe during the
July, 2018

25 yr storm and 100 yr storm. A manning’s N of 0.009 was used for the A-2000 Storm
pipe within the model per the manufactures specifications.
Stormwater Treatment
The City of Bozeman requires infiltration, evapotranspiration or capture for reuse of the
runoff generated from the first 0.5 inches of rainfall from a 24 hour storm. A common
methodology for estimating the volume of direct runoff from a drainage basin is the SCS
method. This method requires basic data similar to the Rational Method: drainage area,
a runoff factor, time of concentration, and rainfall. However, the SCS approach is more
sophisticated in that it also considers the time distribution of the rainfall and an infiltration
rate that decreases during the course of a storm. The SCS method takes into account
the Initial Abstraction (Ia) which is all losses before runoff begins. This includes surface
depressions, water intercepted by vegetation, evapotranspiration and infiltration. Initial
abstraction generally correlates with soil and cover parameters. Through studies of
many small watersheds, Ia was found to be approximated by the following empirical
equation:
Ia = 0.2 x S [eq. 2-2 TR-55]
Where S = (1000/CN) – 10 [eq. 2-4 TR-55]
According to USDA’s Urban Hydrology for Small Watersheds, the Curve Number
associated with soil type B and ¼ acre residential lots is 80 (Table 2-2a). Using the
standard SCS method,
S = (1000/80) – 10 = 2.5 inches
Ia = 0.2 * 2.5 inches = 0.5 inches
Using a 10-year 24-hour rain event in the City of Bozeman the total precipitation (P) is
1.88 inches of which 0.5 inches is lost due to initial abstraction according to USDA’s
SCS method. Therefore this drainage plan includes provision for the first 0.5 inches of
rainfall from the 24-hour storm to be retained in surface depressions, intercepted by
vegetation, or evapotranspired or infiltrated
Stormwater Detention Ponds
Pond 5 and Pond 1A were designed in the original 2013 design report. Pond 1A will
remain the same as originally designed but updated calculations are provided for clarity
and it has been renamed Pond 1B. Pond 5 is similar to the original design but it has
been oversized to account for future development along Vaquero Parkway. This Pond
has been renamed Pond 5B and new calculations have been provided. The ponds are
designed with outlet structures to limit stormwater runoff from the developed site to the
pre-developed runoff rates for the 10-year storm and to not overtop during the 100-year
storm.
With this phase, additional drainage area will be added to the Existing Pond 7 basin.
Pond 7 was originally slightly oversized allowing for this extra volume to be attenuated
without exceeding the predeveloped rate. Revised pond calculations modeling the
existing pond volume and existing outlet structure can be found in the appendices
July, 2018
L:\172708\Engineering Reports\Storm Report\Stormwater Report.doc Page 3
Groundwater
Groundwater is known to be high in this area. A geotechnical report was done in 2001
that included borings near both pond location. ST-29 near Pond 5B showed depth to
groundwater at 3 feet below existing ground and ST-32 near Pond 1B showed depth to
groundwater at 9 feet below existing ground. Due to the high groundwater the maximum
pond excavation depth for Pond 5B is 2 feet.
Culverts
Both culverts under Vaquero Parkway were designed in the 2013 Design Report and
modeled in the flood plain study conducted in 2007. Inverts and length changed slightly
from the original design so new calculations are provided. Both culverts were modeled in
HY-8 for the 25-year storm, 100-year storm, and emergency overflow events.
According to the City of Bozeman standards the emergency overflow capacity shall be
100-percent of the whole culvert for the major storm. Both culverts meet this requirement
by providing the entire emergency overflow capacity within the culvert and without
overtopping the roadway. The headwater depth for the 25-year storm is provided in the
culverts calculations and does not exceed 1.5 times the culvert depth.
Maintenance
Regular maintenance of stormwater facilities is necessary for proper function of the
drainage system. In general, regular mowing of detention pond areas and removal of
debris from the outlet structure will be required to maintain functionality of the system.
Sediment removal from the ponds may be required over time to restore the detention
pond volume. Additional maintenance items include removing debris from inlet grates
and culverts, cleaning and flushing pipes, cleaning manhole sumps, and establishing
ground cover after construction. All of the detention ponds will be maintained by the
HOA (as is with the other existing ponds) after the phases have been incorporated into
the HOA.
