The Knolls at Hillcrest: Linear Park Master Plan
SECTION 1: LOCATION AND HISTORY, AND EXISTING CONDITIONS
LOCATION AND HISTORY
The Knolls at Hillcrest (the Knolls) is a 125-unit age-qualified single-household residential development
consisting of 31.56-Acres. The Knolls is bound by Birchwood Lane to the north, Highland Boulevard to
the east, Highwood Estates to the south, and Burke Park to the west. The Knolls residential subdivision is
the first phase of the Bozeman Deaconess Health Services (BDHS) Development. The legal description
of the property is:
Approximately 31.5 acres, southern portion of COS 2047, Tract 1, located in the northeast quarter of
Section 18, Township 2 south, Range 6 east, P.M.M. City of Bozeman, Gallatin County, Montana.
The area has historically been used for agricultural farming of hay and grain crops. The Knolls have
approximately 2.73-Acres of dedicated linear park and 5.01-Acres of public open space land.
EXISTING CONDITIONS
The Knolls consist of 31.56-Acres that is being subdivided into 76 single-household residential lots,
1 multi-household residential lot (49-unit single-household), and 1 bed and breakfast lot. Existing
conditions adjoining the Knolls site include the Hillcrest Facility to the north, vacant land to the east,
Highwood Estates and the City of Bozeman Water Tower to the south, and Burke park to the west.
The Bozeman Deaconess Health Services Development Subarea Plan was approved by the Bozeman
City Commission on February 27, 2006. The Knolls is the first phase of the BDHS development, and was
conditionally approved for Major Subdivision Preliminary Plat by the Bozeman City Commission on July
24th, 2006. No other phases of the BDHS development have yet to be built.

The Knolls at Hillcrest: Linear Park Master Plan
SECTION 2: PARK AND OPEN SPACE IMPROVEMENTS
PARK AND OPEN SPACE IMPROVEMENTS
GENERAL INFORMATION
The Knolls contains one linear park and open space areas, for a
total of 337,095-square feet (7.74-Acres). The linear park consists
of 119,009-square feet (2.73-Acres) and will serve as an important
passive recreation and pedestrian link from the existing Burke Park
and trail system through to the proposed Highland Glen Park and
trail system. The remainder of the open space system consists
of 218,086-square feet (5.01-Acres) and provides additional
pedestrian connectivity via pathway corridors through this
phase to future phases of the BDHS development.
SITE FURNISHINGS
Site furnishings within the linear park consist of picnic tables,
park benches, trash cans, pet waste stations, and a bike rack
(see Figures 1-5). Picnic tables, trash cans and park benches
(6’ long) will be consistent throughout the BDHS development,
and will consist of jarra hardwood and black powder-coated
steel construction. Bike racks will consist of surface mounted
stainless steel construction and be consistent throughout the
BDHS development. All picnic tables, park benches, trash
cans, and bike racks shall be permanently surface mounted
in place. Pet waste stations will be consistent with those in Burke
Park, and consist of green aluminum construction. Pet waste
stations shall be permanently embedded in place. Refer to
site design drawings for vendor information and schedule
(see Appendix J).
PEDESTRIAN CIRCULATION
Throughout the subdivision pedestrian circulation is facilitated
through a network of sidewalks and trails. Sidewalks in park and open space running alongside streets,
are 6-foot wide concrete as required by the City of Bozeman Standards. These sidewalks connect
pedestrians at trail heads to the meandering trail system. These trails consist of 10-foot wide asphalt
surface running north-south alongside Highland Boulevard, and 8-foot wide gravel trails. The trails
connect from existing Burke Park trails and meander through the Knolls pedestrian corridors, which
will ultimately connect to future trails within the proposed BDHS development. In compliance with the
Design Guidelines for the city of Bozeman Parks, Class II Trails, the gravel trails consist of a two part
tread mix. The first 3” lift consists of 3/4” road mix, compacted, and then 3/8” minus gravel (natural
fines) consisting of 80% sand, 10% silt, and
10% clay. These gravel trails provide a firm
and stable surface. In addition, a disabled
accessible trail connecting dedicated park
parking spaces to Burke Park will be installed.
All trails will be built to the City of Bozeman
Standards (see Figure 6, and Appendix F).

PARKING
Dedicated park parking will be installed (including striping and signage). Parking lot design will conform
to the City of Bozeman Standards. Refer to site layout drawings (see Appendix J).
AESTHETIC AND FUNCTIONAL GRADING
Due to the ridge-line topography of the site, most grading will serve functional purpose. All grading
will be completed in a design manner to provide a pleasant aesthetic experience for the pedestrian
user. Retaining walls, berms, and planting areas will be used throughout the linear park and the open
space areas, providing function and interest to the pathway corridors.
WOODY VEGETATION
All vegetation throughout the Knolls will consist of quality nursery stock. As required by the City of
Bozeman, street trees will be planted in all right-of-way nature strip areas. Street trees will consist of a
variety of large deciduous canopy trees. Through avoiding a monoculture of street trees and planting
a variety of species, the likelihood of large scale tree loss due to disease will be reduced. In addition,
the use of several species of street trees adds additional texture and interest to the streetscape.
Ornamental deciduous trees will be used throughout the linear park and open space areas as
specimen trees. Ornamental trees add seasonal interest through flowering and fall foliage color, as
well as adding a variety of forms and textures to the landscape pallet.
Evergreen trees and shrubs will be used throughout the linear park and open space areas as specimens
and mass plantings. Evergreen plants add winter interest to the landscape, and serve as excellent
natural screens and buffers. Wherever evergreen plants border a trail or sidewalk, they will be placed
so that when they reach their mature spread they will not block walkways.
The City Forester and City Parks Department have final
approval over the final plant species selection of shrubs
and trees prior to construction. Furthermore, no trees
shall be planted within 10-feet of any utilities and must
be placed a minimum of 35-feet from intersections and
sight triangles.
HERBACEOUS VEGETATION
Planting beds are proposed throughout the Linear Park
areas. The planting beds will be lined with Typar weed
barrier fabric, and where planting beds abut irrigated lawn
they will be edged with steel edging. Edging is necessary
to separate landscaped spaces and contain the weed
barrier fabric. Garden will be covered with a 3-inch deep
layer of 1 1/2” washed gravel mulch. All trees in lawn areas
will have a 1 1/2’ radius planting bed with a 3” deep layer
of shredded bark mulch, of local origin and from healthy
trees.

-5-
Throughout the Knolls there are two types of lawn; irrigated and non-irrigated lawn areas. Any areas
that are disturbed during the construction phase will require the disturbed lawn area to be reseeded.
This will be done with a prepared seed bed and reseeded with the appropriate grass mixture for
that area of disturbance. The recommended reseeding method is to loosen the soil to a minimum
depth of 6-inches in order to improve initial root development and then to complete the seeding
with a narrow spacing drill seeder. The soil will not be compacted in any manner. Broadcast seeding
is appropriate for areas with a slope of 3:1 or greater, and the seeding must be raked into the soil.
Seeding ratios and mixes shall be approved by the City of Bozeman Parks Division. The irrigated lawn
mix is recommended for areas that receive rotor irrigation (see Table 1). Areas that are not irrigated
should be seeded with the non-irrigated lawn mix (see Table 2).
IRRIGATION SYSTEMS
All irrigation will be professionally designed and built to the City of Bozeman standards and specifications
and shall be compatible with Maxicom systems. All water lines, with the exception of drip lines, will be
2” PVC scheduled pipe. Drip lines shall be class 160 polyethylene pipe. The linear park will be irrigated
with gear-driven rotor heads that connect with unitized swing joints to the main line. For establishment
purposes, trees located in the non-irrigated open space areas will receive supplementary drip irrigation.
The system will utilize a submersible pump providing the necessary pressure to run the system. Refer
to irrigation drawings (see Appendix J).
As required by the Bozeman UDO a well shall be located on the property to serve the irrigation needs
of the Linear Park. The irrigation system (see Appendix J) was designed based on the availability of a
30GPM well providing approximately 70 PSI at the well head. However, existing wells located near the
Linear Park (The Hillcrest Facility), drilled to a depth of 330-feet only provides 15GPM. If it is not possible
to provide a well that produces 30GPM, it may be necessary to either pursue the possibility of tapping
into city services for irrigation water or to seed the lawn areas with a non-irrigated seed mix (see mix
#2) while providing drip line irrigation from the well to trees and shrubs.

MAINTENANCE
RESPONSIBLE PARTY
The developer will maintain responsibility for park maintenance until a Home Owners Association (HOA)
is established, who will assume control until such time that a City-wide Park Maintenance District is
created to do the same.
MOWING AND WATERING
Turf grasses (irrigated lawn) should be mowed no shorter than 3-inches and allowed to grow to a
height between 4 and 41/2-inches, prior to consecutive mows. Turf grasses should be watered with
12-inches of water between June 1st and September 1st. Peak demand may require as much as 1-
inch of water per week. As lawns mature, watering should be spread evenly through the week and be
applied in less frequent deeper soaks.
Native grasses (non-irrigated lawn) should be mowed at a minimum height of 4-inches, preferably
6-inches. In addition to mowing, native grasses should be burned in late winter or early spring every
three-years. Burning is necessary to control invasive plants, eliminate crop residue and to recycle
nutrients. Native grasses should be watered 3-4 times per year, depending on seasonal moisture. The
first watering should occur at the end of May, the second in mid-July, and the final watering in mid-
October.
Trees and shrubs should be deep watered immediately prior to the ground freezing for the winter.
NOXIOUS WEED CONTROL
A noxious weed control program will be established with a local contractor. In accordance with the
Montana Noxious weed control act, an annual property check with spot spray application will occur
annually each June. This property check shall be coordinated with the county Weed Supervisor and the
NRCS agent. Weeds growing in gravel trails and walkways shall also be controlled with spot application
as needed.
FERTILIZATION
Fertilization of grass and lawn areas should be done as necessary and kept to a minimum. Irrigated
lawn areas should have two annual applications of fertilizer. In May a blend of 17-17-17 should be
applied, and then in mid-summer an application of 27-8-8 blend. During the establishment period,
fertilization should be kept to 40lbs per 10,000 square feet. Established lawn should be fertilized at
60lbs per 10,000 square feet. Soil tests should be taken biannually to assess soil nutrients and adjust
fertilizers as appropriate. Shade trees in irrigated areas should be fertilized in April with 16-10-9 plus
iron and zinc, until established. Once established, shade trees and shrubs should be fertilized with tree
food spikes and should not be fertilized after mid-July.
Non-irrigated grass areas should not be fertilized. As such, no plan for fertilization has been made.
Trees and shrubs located in these areas should be assessed on occasion to determine if they require
capsule fertilization, and then treated as needed. Avoiding unnecessary broad fertilization of these
areas will help to reduce nutrient run-off and pollution within the water ecosystem.
PRUNING
Evergreen species should be pruned annually in June. Deciduous shade trees should be pruned
-6-

-7-
in April, with the exception of Acer species (Maple) and Betula species. (Birch). Maple and Birch
trees should be pruned annually in mid to late July. Throughout the year, trees and shrubs should be
monitored for pests and disease, with the appropriate treatment implemented as necessary.
SNOW REMOVAL
Per the City of Bozeman Ordinance 1529, all sidewalks in the public right-of-way will have snow removed
within 24-hours of the end of a snowfall event. The Knolls HOA will be responsible for assuring the
removal of the snow. Gravel trails will not have a regular snow removal schedule. The City of Bozeman
shall be responsible for assuring removal of snow on the Highland Boulevard asphalt trail.
IRRIGATION SYSTEMS
The irrigation system should be charged in April, after the last frost and when plant material begins to
grow. The recommended charging method is as follows:
All of the manual drain valves should be turned to the “closed” position.
The power for the well pump should be switched to the “on” position.
Program or adjust the controller for the current month’s watering needs.
Check all heads to ensure that there is no breakage and that proper coverage is attained.
During the last week of October, the irrigation system should be winterized. The recommended
winterization method is as follows:
The power to the well pump should be turned off.
All manual drain valves should be opened.
A high powered air pump should be used to connect to many of the quick coupler valves
around the system.
Air should be run through the system, opening and closing each valve zone, until all of the
water is completely out of the system.
The control should then be turned off and the water should be left off until spring.
If winter watering is necessary, this should be done manually from the tank.
Each month the sprinkler heads and controller should be checked and adjusted for the weather.
The irrigation system shall be monitored to watch for breaks, vandalism and overall needs of the site.
When sprinkler heads need repair, repairs should be made with the same brand and nozzles, ensuring
that the coverage is efficient for the working pressure and equal precipitation dispersal rate. The
heads should be checked to ensure that they are seated at a level that will not cause them damage
from mowing or maintenance equipment. Periodically the drip emitters around the trees should be
checked to ensure that they are functioning properly.
ANIMAL CONTROL
In accordance to the Bozeman Municipal Code pets must be kept on a leash, and all pet waste must
immediately be collected by the pet’s respective owner. Pet waste stations will be provided at trail
heads for disposal of pet waste (see figure 4 and Appendix J). If rodent populations rise to a level that
threatens the survival of plantings or public health, they may be controlled. Poisons to control rodent
populations is not acceptable on City of Bozeman owned or dedicated land.

Design Guidelines for City of Bozeman Parks:
* New Park construction must be approved by the Parks Division and the Recreation and Parks
Advisory Board, and must comply with the master plan, if applicable. Any changes must be
approved and / or amended in the master plan.
* Soil Preparation - 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 10 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 ten inches. The sub base, after grading, will be
scarified to a depth of twelve inches to insure drainage throughout the profile.
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.
* Seeding ratios and mixes will be approved by the City of Bozeman Parks Division. Seeding
will be applied with a slit-type or drill-type seeder to insure good soil to seed contact. Before
seeding, the soil shall be loosened to a minimum depth of six inches in order to improve initial
root development. 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. Generally, a seed mix combination of
Bluegrasses and Rye are used in formally maintained Parks. Some low maintenance Kentucky
bluegrasses that perform well are: Kenblue, Park, Plush, Vantage, Victa, Vanessa, Barblue,
Parade and S-21. Perennial ryegrass will be used opposed to annual ryegrass. Athletic fields will
be planted with new-improved Kentucky bluegrass types and new cultivars of perennial rye.
Examples of some of the new, aggressive types of KBG’s are as follows: Award, Total Eclipse,
Midnight, Nustar, Ram I, Limousine and Touchdown. Lower maintenance parkland may require
different seed mixes, and will be specified by the Parks Division.
* Irrigation systems will be compatible with Maxicom systems. All water lines shall be
schedule 40 PVC. Black Poly pipe is unacceptable. 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
64
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.
* Wells installed on City of Bozeman property must be registered in the City’s name. All wells
must have a stainless steel screen at the intake.
* Playgrounds must be installed on Park land managed by the City of Bozeman. All
playgrounds must be approved by a Certified Playground Safety Inspector (CPSI) and meet
ASTM F1487-01, CPSC and ADA guidelines and specifications. Playgrounds shall be age
appropriate, for area served, and be signed accordingly. There must 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 must be supplied to
the City of Bozeman’s Parks Division, upon completion of playground installation. All work will
be overseen and approved by a CPSI. No wooden structures will be approved.
* Fencing shall be constructed with 9 gauge, commercial grade, chain link fabric. All posts and
top rails shall be schedule 80 galvanized pipe. Corner post will be 2 and 3/8 “, line post will be 1
7/8", top and bottom rails will be 1 1/4". All post are to be set in concrete, spaced at 10 foot
intervals, and a concrete pad, 12" in width and 4" in depth shall be installed beneath the fence
line, along the entire length. A bottom rail will be installed between all sections of fence for the
purpose of tying the fabric down as well as maintaining the strength and integrity of the fabric.
Appropriate heights of fences shall be determined by the City of Bozeman Parks Division.
If the subdivision includes a public dedicated Lake, the water shall be tested twice a year, once in
the spring and once in the fall, by the developer until the Homeowner’s Association forms at
which time the HOA assumes the responsibility for testing. Testing shall include test for Fecal
Coliform, Fecal Enterococci, Staphylococcus, and Pseudomonas and copies of reports shall be
submitted to the City of Bozeman Parks Division for their records.
* Trail Classifications
Class IA – These trails are heavily used with full access and are designed for recreational and
commuter use along major transportation corridors. These trails are designed to permit two-way
traffic using an impervious surface material such as asphalt or concrete. These trails are 12 feet
wide. There is full *ADA accessibility.
Class IB – These trails are the same as Class IA trails with the exception of being 10 feet wide.
These trails are typically used in interior sub-division settings where Class I trails are appropriate
but do not require a full 12 foot width.
Class IIA – These trails receive heavy to moderate use with a very high degree of ADA
accessibility. They are intended for multiple non-motorized, recreational and commuter use.
Class II trails are constructed of Natural Fines and are 6 feet in width.
65
Class IIB – These trails receive moderate use and provide moderate ADA accessibility
depending on grades and/or obstacles. Construction standard is the same as Class IIA.
Class III – These trails receive moderate to low use and are typically 3 feet in width. They are
either natural trails, developed by use, or constructed with Natural Fines. ADA accessibility is
extremely limited.
Class IVA – These trails are generally mowed corridors used for ski trails in winter, or
occasional special activities, and are 16 feet in width.
Class IVB – These trails are the same as Class IVA trails with the exception that they are 10 feet
in width.
Class V – These trails are used for equestrian traffic and when constructed parallel to pedestrian
trails, are built with a sufficient buffer and physical barrier between them to prevent
horse/pedestrian conflicts.
* Class I Trails must support a minimum of 12,500 pounds. Asphalt - Width of trail shall be a
minimum of 10 feet with a min. cross slope of 2% or max. 5% and a 1 foot wide gravel border
along each edge. Trail bed shall be excavated to a minimum depth of 11.5 inches. A soil
sterilant, approved by the City of Bozeman Parks Division, shall be applied to trail bed prior to
construction. Trail bed shall consist of a minimum of 9 inches of crushed gravel compacted to
95% of max. density as determined by AASHTO T99, unless otherwise dictated by sub-soil type
materials being compacted to road standard. The overlay shall consist of 2.5 inches of asphalt
compacted to 93% of max. density, as determined by ASTMD 2041. Construction seal shall be
applied at .08 gallon / square yard after installation. Concrete – Width of trail trails shall be a
minimum of 10 feet with a min. cross slope of 2% or max. 5%. Trail base shall consist of a
minimum of 3 inches of crushed gravel compacted to 95% of max. density as determined by
AASHTO T99. Concrete shall be a minimum of 6 inches of M4000 reinforced with 1.5 lbs. per
cu. yd. of Fiber mesh. Where terrain allows, slope of trail should not exceed 12:1.
* Class II Trails shall be a minimum of 72 inches in width. Trail bed must be excavated 6
inches deep, prior to installation of tread mix. Tread mix shall be installed in two parts. The first
3 inch lift shall be of ¾” Road mix, compacted, and then 3/8th inch minus gravel (natural fines).
Natural fines used for these trails shall consist of 80% sand, 10% silt and 10% clay. If the
material falls outside of these parameters, the City Of Bozeman Parks Divisions must be
consulted for approval or modification. If the natural fines tread mix does not contain enough
clay or silt binder, additional binder must be mixed in. Alternative soil stabilizer products are
acceptable, but must be approved by the City of Bozeman Parks Division. Trail bed must be
filled up to original surface along both edges with a cross slope of no less than 2% and no more
than 5% to provide for water drainage. Tread mix must be rolled flat and compacted after
installation, maintaining a 2% to 5% cross slope. (If moisture content is not adequate for
compaction, water should be added prior to rolling and compacting). Where terrain allows, slope
of trail should not exceed 12:1 with a cross slope no greater than 20:1 (5%) to provide for ADA
accessibility. All damage to surrounding features and/or vegetation shall be reclaimed
immediately. Encroaching weeds, due to trail construction, shall be treated and controlled for a
minimum of 2 years after trail section is completed. Minimum overhead clearance shall be 96"
for pedestrian and bike traffic, and 120" for equestrian traffic.
* Street/Trail Connections - Mid block trail crossing shall have a painted pedestrian
crossing with crossing and advanced crossing signs at either end. Curb cuts shall be provided at
all street / trail connections.
66
* Full ADA trail accessibility is defined as a slope not exceeding a 12:1 angle and
a cross slope of no more than 2%. There can be no abrupt change in surface level greater than ½
inch.
* Bridges shall have a minimum width of 96 inches, to allow wheelchair turn around and
passing. Height of bridge is measured from bridge deck to bottom of stream or river. If deck is
more than 30 inches high, a protective rail is required. Rails are to be 42 inches high, with at
least one midrail at 34 inches, to be used as a handrail. A protective barrier must be installed
along the length of the rail system with either solid paneling or vertical bars. Spacing between
