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. 47 -3- 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). Figure 3. Trash Can Figure 2. Picnic Bench Figure 2. Park Bench Figure 5. Bike RackFigure 4. Pet Waste Station Figure 6. Gravel Trail Cross Section 48 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.

IRRIGATED LAWN MIX (SEED MIX #1) GRASS SPECIES PERCENTAGE OF MIX Kentucky Bluegrass 60% Perennial Ryegrass 25% Creeping Red Fescue 15% Drill Seed at 5lbs. Per 1000-square feet. Double the rate for broadcast seeding. TABLE 2. NON-IRRIGATED LAWN MIX (SEED MIX #2) GRASS SPECIES PERCENTAGE OF MIX Western Wheatgrass 40% Slender Wheatgrass 20% Thickspike Wheatgrass 10% Bluebunch Wheatgrass 10% Sheep Fescue 10% Sherman Big Bluegrass 10% Drill Seed at 10lbs. Per acre. Double the rate for broadcast seeding. 49 -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. The Knolls at Hillcrest: Linear Park Master Plan SECTION 2: PARK AND OPEN SPACE IMPROVEMENTS 50 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- The Knolls at Hillcrest: Linear Park Master Plan SECTION 3: MAINTENANCE 51 -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. §§§§ §§§ § § The Knolls at Hillcrest: Linear Park Master Plan SECTION 3: MAINTENANCE 52 APPENDIX The Knolls at Hillcrest: Linear Park Master Plan SECTION 4: APPENDIX -8- 53 54 55 56 57 58 59 60 61 62 947E350D 350C 350C 350D 947E 72D407A SOIL CLASSIFICATION MAP 350D 947E BLACKMORE SILT LOAM 8-15% SLOPES REEDWEST-CABBA-BOWERY COMPLEX 15-45% SLOPES Map Symbol 72D 350C Soil Type DOUGHTY LOAM 8-15% SLOPES BLACKMORE SILT LOAM 4-8% SLOPES Note: Soil Survey Data obtained From NRCS Study. FIGURE 11B NOT TO SCALE North 63 October 25, 2006 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.
