PROJECT LOCATION AND HISTORY
The Cottonwood Project is located of Huffine and Cottonwood Rd. in Bozeman. The land that
makes up the The Cottonwood Project Subdivision has been used primarily for agriculture and
livestock production for many years. The site is predominately grass land and agricultural land.
Project Scope
The Cottonwood Project Master Park Plan is comprised of three main components: Dedicated
Park areas, Common Open Space areas (with Public Access Easements) and a Linear Park. The
primary purpose of this document is to describe the initial level of development and
maintenance of the parks, trails and common open space. The second objective is to show a
concept for future recreation facilities that could complement those installed by the developer.
Guiding Ideas:
• Provide connections between residential neighborhoods and park / open space areas.
• Provide variety in recreation experiences and opportunities
• Provide areas for passive and active recreation
• Protect, retain and improve native and natural drainage corridors
• Minimize hard or impervious surface
• Address current parkland needs while also minimizing impacts to wetlands and streams
Dedicated Parkland and Common Open Space
Dedicated Parkland and Common Open Space will make up 5.5 acres of The Cottonwood
Project subdivision. The Central Park and Linear Park Provide 4.28 acres of total dedicated
parkland.
The following section outlines the installation and maintenance of all dedicated park areas for
Final Plat filings. The plan puts emphasis on open, maintained areas for passive and active
recreation. There will also be a playground with age appropriate equipment, which will be
installed with Intent for construction. Part of the parkland is adjacent to a watercourse corridor
and the natural character of this area will be maintained to the greatest extent possible
Linear Park and Open Space Trails
In the Linear Park and Open Space areas of the project, the Developer will install and maintain
8' paved multi-use trail (Asphalt) (Class II Trail). It is the intent to create a more park like
experience along the edges of the development. These trails will also serve as important
linkages to existing and planned community amenities. All landscape standards for street trees,
landscape and irrigation will be adhered to.
The Cottonwood Project July 2019

Parkland and Open Space Amenities
The development of Parkland amenities will be installed by the developer as necessary to meet
the Parks Master Plan goals. The current list of planned amenities includes:
1. 6’ wide Class II trail through Central Park – Asphalt
2.8’ wide Class II trail through Linear Park – Asphalt
3.Benches at intermittent intervals along streams and paths where necessary
4.Playground along with shade pavilion with tables, benches, trash receptacle and bike
racks
Financing: All Parks, Open Space, street boulevards adjacent to the parks and detention storm
water basins for any phase of the subdivision will be bonded with the Final Plat for that phase.
A cost estimate has been provided under Section 5.
Construction: Any and all site work (including trails) must be preceded by a preconstruction
meeting with the City of Bozeman. All plans, improvements, structures and plantings must be
approved by the City prior to installation. Building Permits are required for any structural
improvements. Any deviation from the Park Master Plan must be submitted to the City and
approved before construction.
Vegetation
All vegetation shall be quality nursery stock and construction documents will dictate further
specifications and species selection. A variety of species shall be selected to ensure that a pest
or disease event does not decimate the entire project. Trees, shrubs and herbaceous plants will
be chosen for their size, hardiness and aesthetic nature. Plants used will be regionally native
and/or adapted to the extent possible.
Trees
All trees are subject to approval by the City of Bozeman. Tree selection should be based on the
recommended species list provided by the City of Bozeman. Tree size and selection shall be
varied in order to create visual interest and a varied genetic palette.
Recommended Tree List
Colorado Blue Spruce
Northwoods Red Maple
Quaking Aspen
Cottonwood
Common Honeylocust
Spring Snow Crabapple

The Cottonwood Project
Park Master Plan
Shrubs
Shrubs used within the watercourse setback will be used to enhance the existing native
vegetation, increase native habitat and provide a varied visual experience. Plants will be
chosen based on hardiness, aesthetic quality and size. The City Forester will approve final
plant selection for all woody plant material.
Recommended Shrub List
Red Osier Dogwood
Geyer Willow
Yellow Willow
Native Chokecherry
Grasses
Herbaceous seed mixes will be dictated by the construction documents. In general, turf areas
will receive a Kentucky bluegrass mix, detention areas will be seeded with a mix tolerant of
wet conditions. All areas disturbed by construction will be properly prepared and seeded with
a narrow spacing drill seeder. Before seeding, the soil shall be loosened to a minimum depth
of six inches in order to improve initial root development and amended if necessary. The soil
will not be compacted in any manner. Sufficient compaction is readily achieved through the
grading process and normal rainfall. Fertilizer should be applied prior to planting to insure
healthy plant development.

Irrigation
All irrigation systems will be designed to meet City of Bozeman requirements.
Irrigation systems will be compatible with Maxicom systems or approved alternate. All water
lines shall be schedule 40 PVC or Black Poly pipe. Pipe shall be installed at a minimum depth of
twelve (12) inches, main lines at eighteen inch minimum depth. If this depth is unachievable,
the Parks Division must be consulted. No stacking of irrigation lines shall be permitted. Four (4)
inches of sand shall be placed beneath pipe, and four (4) inches of sand above the pipe, to
prevent compaction and settling. Sprinkler heads will be installed on manufactured swing joints
(schedule 80 w/ o-rings). Heads to be installed must be approved by the Parks Division and shall
be gear driven, with interchangeable nozzle sizes, unless noted otherwise, and shall be capable
of producing the specified gpm and coverage area and shall be set to manufacturers’
specifications. Electrical locate tape shall be installed along all lines. Upon completion of
installation, all warranty and maintenance information, as well as well logs and pump
warranties and information, if applicable, and an “as- built” map shall be supplied to the City of
Bozeman Parks Division and HOA.
Soils
All soils to be used on public park land shall be inspected by and meet the approval of City of
Bozeman Parks Division Staff prior to installation and shall meet the minimum depth
requirement of 6 inches. All rock in excess of 1 inch in diameter shall be removed. Soil tests (a
sieve analysis and soil analysis) shall be performed prior to planting to determine the
classification and texture of the soils, along with any nutrient deficiencies. The classification and
texture will determine what amendments, if any, are needed, while the soil analysis will help
correct any nutrient problems with a pre-plant fertilization.
* Guidelines for soils - The soil will be deemed acceptable if: it is less than 35% clay and less
than 70% sand and 70% silt. Ph must not exceed 8.4. The soil will be screened at 1” minus for
rocks and debris; topsoil depth will be at least 6 inches.
Amendments may vary depending on existing soils but will generally consist of 60% coarse sand
(generally concrete sand), 20% organics (C: N ratio below 30) and 20% approved native soil.
Soils will be mixed, prior to installation, with a screener / mixer machine, or applied in layers on
site and mixed thoroughly with a deep rototiller. Depth of amended soil will be a minimum of
ten (10) inches. There will be no compaction following the grading process. Fertilizer, and the
rate at which it will be applied, should be dictated by the soil test report.
Playgrounds
Playgrounds shall be installed on Parkland managed by the HOA (or by the City of Bozeman at
such time as a Park Maintenance District is created). All playgrounds must be approved by a
Certified Playground Safety Inspector (CPSI) and meet current ASTM, CPSC and ADA guidelines
The Cottonwood Project July 2019
Park Master Plan

and specifications. Playgrounds shall be age appropriate, for area served, and be signed
accordingly. There shall be an adequate use zone area around equipment, approved material in
use zone, which meets impact attenuation criteria as specified in ASTM 1292, and adequate
drainage. All installation plans, materials list, construction guidelines, maintenance information
and manufacturer’s name shall be supplied to the HOA/City of Bozeman’s Parks Division, upon
completion of playground installation. All work will be overseen and approved by a CPSI.
Kompan is the recommended structure and final selection will be subject to City of Bozeman
approval. Cut sheets for preferred equipment are provided in this submittal under Section 4.
Maintenance
Responsible Party
The Association shall be responsible for liability insurance, local taxes and maintenance of
recreation and other facilities in the common space areas. The assessments levied by the Board
for the maintenance, upkeep, repair and operation of common areas like all other assessments,
become a lien on each lot within The Cottonwood Project Subdivision. The Board may, in its
discretion, adjust the assessments to meet the changing needs of the community and the areas
serving the community.
The Association shall enter into an annual contract with a certified landscape nursery person for
upkeep and maintenance. The Association will be responsible for park maintenance until such
time a City-Wide Park Maintenance District is created. The Association shall also be responsible
for the maintenance of all common properties, paths and trails, facilities, centers, and adjacent
sidewalks and/or landscaping in street boulevards.
The Declarant will be responsible for maintaining pathways, open space and parkland until 50
percent of the lots are sold. At such time, the Association will take over maintenance.
Maintenance will include the following as well as care and replacement of playground
equipment (CPSI approved) and/or site furnishings, replacement of doggie pick-up bags and
emptying of refuse containers. Any and all work and/or park fixtures must meet standards set
by the City Parks Division.
Trees and Shrubs
A contractor will be hired to perform park maintenance. Maintenance duties to be performed
will consist of spring and fall clean up, routine mowing, lawn patching, care and replacement of
dead trees and/or shrubs. All tree trimming and pruning must be performed by a certified
arborist as outlined in City Ordinance 12.30.040 in coordination with Forestry Division. All trees
on public property are subject to City of Bozeman permits and ordinances.
The Cottonwood Project July 2019
Park Master Plan

Trails
Natural fines trails will not be plowed. These trails will be inspected regularly and receive
routine patching and surface maintenance to prevent erosion or unsafe conditions. Weeds on
the trails well be controlled following City of Bozeman standards, set by the City Parks Division,
and using industry standards or as part of the weed control plan described in this document.
Turf Care
Native grass areas should be mowed 3-4 times per year dependent on rainfall levels. The first
mowing should occur at the end of May, and the second time should take place around mid-
July, with the final mowing in Mid-October.
Kentucky bluegrass areas should be maintained between 2"-4 1/2" and should receive
approximately 12" water between June 1st and late September. This translates to about 1"
water per week for lawn areas. Mowing will not be done during extremely wet periods or when
sub-grade is saturated or with standing water. Established lawns can receive a deep, but less
frequent watering in order to conserve and not over water.
Noxious Weed Control
A weed control program will be developed that conforms to the requirements of the City of
Bozeman, Gallatin County Wed Control Board Supervisor and NRCS. This program will consist
of an annual visit in June to spot spray where necessary, including trails and sidewalks. Weeds
will be sprayed by a licensed contractor, according to industry and local standards, on a regular
basis, using appropriate applications and products. The utmost care will be taken to protect
water sources, park users and adjacent property owners. The City of Bozeman shall be notified
of any and all applications of pesticides and/or herbicide on public lands. Signs shall be posted
prior to application in appropriate and noticeable locations identifying the product applied and
the date applied. Signs will remain in place for a minimum of two days after treatment.
Records shall be maintained in accordance with State of Montana Pesticide Act, Administrative
Rule 4.10.207 and copies submitted to the City of Bozeman Parks Division.
Fertilization
Fertilization should be minimized to prevent unnecessarily high amounts of nutrients running
off into streams and wetlands on and off the site. No fertilizer should be applied within 50ft of
streams or wetlands to further minimize the potential for contamination through run-off. Trees
and shrubs inside the 50ft buffer should be monitored and if fertilization is necessary, capsule
fertilizer should be used.
Lawns should be fertilized once in spring with a 24-4-24 blend after the last frost and with a 21-
3-21 in mid to late summer. It is recommended that slow release fertilizer be used to prevent
excessive shoot growth and to provide turf nutrition over an extended period. Lawns should be
The Cottonwood Project July 2019
Park Master Plan
8
fertilized according to manufacturer standards. Annual soil test should be performed to check
nutrient levels and determine whether changes are necessary.
Outside the 50ft buffer, shade trees should be fertilized in April with a 16-10-9 blend plus iron
and zinc. Other trees should be fertilized with food spikes, but no fertilization of woody
vegetation should occur past mid-July. Trees under one year old should not be fertilized.
Evergreens should be pruned as necessary in June and shade tree pruning should be done in
April, except for birches and maples. Birches and maples should be pruned in mid-July to
prevent bleeding. All trees should be continually monitored for pests and diseases throughout
the growing season. Woody vegetation should be deep watered right before the ground
freezes.
Snow and Leaf Removal
Snow removal will be provided within the park by a snow removal service retained by the
Neighborhood Association. Sidewalks must be cleared within 24 hours after the end of a
snowfall event per Bozeman Ordinance 1529. The Home Owner’s Association will be
responsible for clearing snow on sidewalks, walks adjacent to Parks and Open Spaces. Leaf
removal will be provided most likely by a landscape contractor or handyman service, as
retained by the Neighborhood Association.
Playground Inspection
Playground inspection should be performed on an annual basis by an independent contractor
certified as a National Certified Playground Safety Inspector. The inspector shall submit a
report to the City of Bozeman Parks and Recreation Department. The Neighborhood
Association is responsible for hiring the independent contractor.
Irrigation System
The irrigation system should be charged in May, after the ground thaws and plants start
growing. The manual drain valves should be turned to the closed position and well pump
power switch turned on. The controller should be programmed for the anticipated water
requirements for the current month. All heads should be checked for breakage and proper
coverage and check on a monthly basis for necessary adjustments. Drip emitters should be
periodically checked, and the entire system should be regularly monitored for line breaks,
head breakage and vandalism.
The Cottonwood Project July 2019
Park Master Plan
9
Head replacement should be done with the same brand to ensure efficient coverage for the
system working pressure and dispersal at an equal precipitation rate. The height of heads
should be checked to avoid damage from mowers or maintenance equipment.
Winterization should take place during the last week of October. Power to the well pump
should be shut off and all manual drain valves opened. To flush out the lines, a high-power air
pump shall be connected to the quick coupler valves and air should be run through the system.
Each valve zone should be opened and closed until all water is completely flushed out, then the
controller should be turned off and water left off until spring. Any necessary watering during
the winter months should be done with a tank to prevent damage to the irrigation system.
Animal Control
Pets should always be leashed while in the parks and open space in addition residents must
clean up after their pets. If rodents become a problem with regards to damaging plant material
or posing a health risk to residents or pots, rodent control should be utilized. However, no
poison is permitted on within parkland or open space areas.
Refuse
Refuse within the parks and open space will be collected weekly by a service retained by the
Neighborhood Association or the party responsible for maintenance.
