HomeMy WebLinkAboutDesign Objectives Plan Update for the North 19th Ave/Oak St Entryway Corridor DESIGN OBJECTIVES PLAN UPDATE FOR THE NORTH 19TH AVENUE/ OAK STREET ENTRYW AY CORRIDOR Objectives . The southerly portion of the North 19th Avenue corridor should continue to be residential or residentially compatible in character. . Planned unit developments that mix uses together and assure compatible designs are required. . Signage should not be the dominant visual feature of the corridor and be inte- grated with the developments with which it is associated . Large expanses of visually intrusive and uninterrupted parking should be strongly discouraged. . Provide pedestrian and bicycle circulation within and between projects. Street frontage paths should be integrated with landscaping design, including berming, stone- work, and other diverse features and provide viewing opportunities for the mountains. DOP UPDA TE-l Location: North 19th/Oak Street Subject: Site Development Intent: Create an attractive principal entryway into the city. Guideline: A.l. Commercial development should have considerable emphasis on qual- ity of design and landscaping. Buildings should be grouped and inter- spersed with significant areas oftrees and other vegetation. Watercourses and other natural features should be integrated into the design. Example: DOP UPDA TE-2 Location: North 19th/Oak Street Subject: Site Development Intent: Minimize visual impact of parking lots. Guideline: A.2. Along street frontages, earth berms, hedges, plant groupings, or similar means should be installed to reduce the visual impact of parking lots. Use ofa diversity of plant materials for seasonal color and visual inter- est is encouraged. Illustration: ~ ~~~. Example: DOP UPDATE-3 Location: North 19th/Oak Street Subject: Site Development Intent: Facilitate pedestrian and bicycle circulation Guideline: A.3. Provide pedestrian and bicycle circulation within and between projects. Street frontage paths should be integrated with landscaping design, in- cluding benning, stonework, and other diverse features and provide view- ing opportunities for the mountains. Example: Example: DOP UPDA TE-4 Location: North 19th/Oak Street Subject: Building Design Intent: Reduce the visual impact of boxy buildings that contrast with the surroundings Guideline: 8.1. Pitched roof forms are strongly encouraged, as are awnings, wall off- sets, and similar means to break up the massing of buildings. Example: Example: DOP UPDA TE-S --..-.. .....---.----- _______....___n.__.'.. Location: North 19th/Oak Street Subject: Building Design Intent: Minimize elements that distract from distant views. Guideline: 8.2. Discourage the use of bright colors, except for accent trim. With respect to materials, wood or masonry are preferred over other materials for exterior wall finishes. Example: Example: DOP UPDATE-6 Location: North 19th/Oak Street Subject: Building Design Intent: Create a sense of entering the city. Guideline: 8.3. Buildings should be designed to reflect regional urban character, his- tory, and climate. Standardized "franchise" style architecture should be strongly discouraged. Example: Example: DOPUPDATE-7 Location: North 19th/Oak Street Subject: Signs Intent: Minimize disruption of views and quality of the landscape. Guideline: C.!. If freestanding signs are used, they should be monument style, low in height and low-key in colors and lighting; or consolidate pole style signs into in limited locations with architectural integration with the develop- ment they serve. The applicant must demonstrate that the proposed sign will not disrupt view of mountains nor utilize colors and lighting that will detract from the design character of this corridor. Deviations from basic code provisions are strongly discouraged. Illustration: Example: DOP UPDA TE-8 n__._."., "..u__ Location: North 19th/Oak Street Subject: City Actions Intent: Enhance the sense of arriving at the central area of the city. Guideline: D.l. The City should install regularly spaced trees and groundcover within the wide median between Main Street and Durston Road. The recom- mended trees are Mountain Ash, Japanese Tree Lilac, or Amur Maple. The median treatment could be either formal or informal in nature. III ustrati on: !-u Example: DOP UPDA TE-9 -..--- SPECIFIC DEVELOPMENT STANDARDS SECTION A. PUD REVIEW PROCEDURES. Approval of a development proposal located in the North 19th Avenue or West Oak Street entryway corridor shall be subject to the planned unit development review procedures and shall consist of the three procedural steps as required by Section 18.36.040, BMC, pre-application review, preliminary plan review and final plan review. SECTION B. DEVELOPMENTAL GUIDELINES SUBMITTAL REQUIREMENTS. Applications for PUD review in accord with this section shall submit developmental guidelines to the Planning Office as part of the preliminary plan application as required by Section 18.36.070.0.2 of Title 18, BMC, and shall in addition include the following: 1. Architectural Guidelines: building orientation, off-street parking lot orientation, sign guide~ lines, lighting, dimensional guidelines, mechanical equipment screening; 2. Landscape Guidelines: entryway corridor landscape guidelines, streets cape, off-street park- ing lot screening, outdoor storage/display areas, perimeter buffering from other land uses, arterial noise buffering, development entrance, protective covenants; 3. Pedestrian Circulation: between off-street parking lots, between adjacent lots, coordinated sidewalk system, bicycle circulation, trails / pathways. SECTION C. OPEN SPACE PROVISIONS. Sufficient open space along the entryway corridors is necessary to provide the urban streetscape and park- like setting envisioned by the community that is essential to the basic quality of life in Bozeman, and to create attractive entryways into the city: 1. General Standard. Development in the North 19th Avenue and West Oak Street entryway corridors shall generally provide at least the minimum area of the project required by 18.34.090. E as developed open space, exclusive of required off-street parking lot interior landscape. Public streets located in dedicated public rights-of-way shall be excluded from the gross area of land in calculating open space requirements. However, private streets, driveways, off-street parking lots and other private areas shall apply in determining the total gross area. Open space in the front yard setbacks for each zone may contribute to the required open space provision. Property located outside, but adjacent to the entryway corridor overlay, which provide linked common open space arcas, and contributes to the intent and purpose of this section may be applied towards thc open space provisions based on the merits of the proposal and its ability to accomplish the goals and objectives of the Nortll 19th Avenue/West Oak Street Corridor Master Plan. 2. Reduction in Open Space. Reduction in the required open space provision to not less than 75 percent required amount may be granted by the City Commission after considering the recommendation f01warded by the DRC and DRB. The planning staff shall solicit com- ments and recommendations from the design review board, Bozeman tree advisory board, Bozeman recreation advisory board and other appropriate sources of professional exper~ tise, which will also be forwarded to the city commission. The criteria for granting a reduc- tion in open space shall be based on the proposal's ability to achieve the goals and objec- DOP UPDATE-10 tives of the North 19th Avenue/West Oak Street Corridor Master Plan based on superior design and phnning techniques exceeding the reguhtory standards set forth in this section. The criteria for granting reduction in the open space provision may include, but are not limited to: a. Exceptional architectural and hndscape developmental guidelines; b. Designation (i.e. public dedication or easement) for use by the general public of pedestrian pathways and/or trailways within the development which are located along entryway corridors, stream corridors or within the interior of the develop- ment, exclusive of sidewalks located in the public right-of-way; c. Public plazas, courtyards, promenades or other usable public areas; d. Front yard setbacks along entryway arterial streets that exceed the minimum fifty (50) foot setback; e. Additional hndscaping installed within the entryway corridors beyond what is re- quired by this section; f. Larger landscaping installed within the fifty (50) foot wide setback along entryway corridors; g. Landscaped areas exceeding minimum yard setbacks situated at main entrances into the development; h. Installation and maintenance of streetscape furniture along greenway corridors; 1. Additional setback and buffering between building sites and areas designated as environmentally sensitive hnds; j. Changes in texture and use of materials at intersections of pedestrian and vehicu- lar circulation; k. Exchange of land within the development for additional land transferred to Rose Park; and I. Preservation of viewsheds (i.e. one-story buildings along entryway corridor or lim- ited building height). 3. Common Open Space. At least one-half of the required open space, shall be in common ownership of the property owner's association or in the form of common open space easements granted to the property owner's association. Landscaping shall be required for all areas of the development which are to be in common ownership or designated as "com- mon open space easements" located on individual lots or parcels of land, and in particular shall incorporate the required landscape for implementation of the greenway corridors. SECTION D.GREENWAY CORRIDOR LANDSCAPE STANDARDS. Development of greenways along the entryway corridors have been established in order to demonstrate the importance of urban open space and to visually enhance aesthetically pleasing, high-quality develop- ment along the arterial corridors of North 19th Avenue and West Oak Street. 1. General Standards. The following landscape guidelines have been designed to develop a formal streets cape in concert with a park-like setting along the greenway corridors as an integral element in developing attractive entryways into the city. All three options may not be applicable in all circumstances. a. Formal Streets cape. Street frontage landscape located in the street right-of-way DOP UPDATE-l 1 boulevard will be characterized by a formal arrangement of large canopy boule- vard trees as follows: (1) One large canopy boulevard tree, a minimum of eight (8) feet in height or 11/2" caliper and planted at regular intenrals of fifty (50) feet on center. (2) Acceptable large canopy boulevard trees include the following species: Ash, Patmore Green (Fraxinus penn.rylvanica); Honeylocust, Seedless (GleditJia triacanthos); Ash, Black (Pra;",'inus nigra); and Maple, Norway (Acer Platanoides). b. Greenway Park. Greenway corridors located in the 50-foot setback will be charac- terized by informal vegetative planting of trees, shrubs, berms and ground cover for everyone hundred (100) feet of frontage along the entryway corridors as listed below. Acceptable tree species for greenway corridors shall consist of the land- scape types listed in the Tree Selection Guide prepared by the Bozeman tree advi- sory board, and made available in the Bozeman planning office. (1) A total of four (4) evergreen and deciduous trees at random or in cluster arrangements, with no more than fifty (50%) percent being deciduous, a minimum of 8-10 feet in height, or 1 Yz" caliper; (2) A total of two (2) small ornamental trees at random locations, a minimum of 8 feet in height, or 1 Yz" caliper; (3) A total of six (6) deciduous and/or coniferous large shrubs, of which three (3) shall be flowering shrubs, at random locations and a minimum of W/2 feet in height at maturity, 2-3 feet installation size; (4) As an alternative to subsection (D)(1)(b)(3) of this section, earth berms, an average of 3.5 feet in height, planted with shrubs or living ground cover so that the ground will be covered within 3 years; and (5) All other areas not landscaped with trees, shrubs or ground cover shall be planted with a drought resistant "native grass" mix consisting of: 17Yz(Yo sheep Fescue; 17Y2% Revenue Slender Wheatgrass; 35% Secar Bluebunch Wheatgrass and 30% Critana Thickspike Wheatgrass. Alternatives to this mix may be considered where it can be demonstrated that the same objec- tives are achieved with an alternative drought resistant grass seed mix. (6) Areas designated for detention and/ or retention ponds for stormwater run- off from development on building sites shall not be permitted in the 50- foot greenway corridor(s), unless all of the following standards have been satisfied: (a) Not more than one-third (1/3) of the greenway corridor setback along the frontage of each individual lot is used for the purposes of retention/ detention ponds; (b) Location of retention/detention ponds do not conflict with, or are justification to alter, design guidelines and location of greenway corridor landscape, pathways, streetscape furniture or lighting fix- tures; (c) Retention/detention ponds demonstrate superior design and treat- ment of storm water runoff, as well as excellence in integration with greenway corridor landscape, and do not exceed a maximum slope of 1 :3; and (d) Groundcover for retention/ detention ponds shall consist of "na~ tive grass" seed mix as specified above in item 5, similar turf grass, DOP UPDA TE-12 ---.--..-..,. or a groundcover certified by a licensed nurseryperson. Not more than thirty (30%) percent of the area shall consist of non-organic groundcover if used as a decorative landscape feature. c. Clusterine landscape. Major entryway locations into development along North 19d1 Avenue and West Oak Street shall contain the following clustered landscaping treat- ment: (1) For every 100 feet of corridor frontage (or portion thereof), a minimum of ten (10) large and small trees, two (2) small ornamental trees, six (6) large shrubs, six (6) large flowering shrubs, twenty (20) small shrubs and twenty (20) small flowering shrubs. 2. Landscape Maintenance and Irrieation. a. Installation. Installation of on-site landscape improvements, to include greenway corridor(s), shall be the responsibility of the land owner of each individual lot at the time of development of said property. Development of areas designated as common open space for the development shall be the responsibility of the PUD developer at the time of subdivision and planned unit development review and approval; b. Maintenance. Maintenance of boulevard streetscape, greenway corridors and com- mon open space areas shall be the responsibility of the property owner's associa- tion and shall comply with the provisions set forth in Sections 18.48.100 and 18.72.040.B of this tide, whereby all required landscape must be maintained in a heald1Y growing condition at all times, and that any plant that dies must be replaced with another living plant that complies with the approved landscape plan. Mainte- nance shall consist of mowing, removal of litter and dead plant materials, neces- sary pruning and irrigation. Where pedestrian or bicycle pathways are located wid1.in the greenway corridor, these trails shall be maintained to provide for their safe use, including pruning of plants to remove obstructions, and removal of dead plant materials, litter, or od1er hazards; c. J .andscape I rrigation. Landscape irrigation shall be supplied by the owner of each building site by a shallow well pump, municipal water system or other acceptable irrigation system. Irrigation shall be piped to each individual planting area by an automatic sprinkler system or other acceptable irrigation system designed to irri- gate all landscape features and areas, and shall include a "bubble" irrigation system for all trees and large shrubs. Alternatives to an automatic sprinkler system shall be designed and certified by a licensed landscape irrigation professional. SECTION E. PEDESTRIAN AND BICYCLE TRAILWAYS. Pedestrun and bicycle trails designated in the North 19th Avenue/West Oak Street Corridor Master Plan shall be implemented during planned unit development and subdivision review of development proposals located in the sub-area phn of this section. Prior to receiving final subdivision and planned unit develop- ment approval, the developer must either install the full trail improvements or provide payment into a North 19th Avenue/West Oak Street Corridor Trails Trust Fund. Should the community choose to con- struct trailways for use by the general public prior to development of said property, the land owner may execute the necessary pedestrian and bicycle trailway easement for installation and maintenance of said trail(s). Pedestrian and bicycle trailways shall be designed and installed in conformance with the following: DOPUPDATE-13 1. Greenway Corridor. A curvilinear asphaltic surface, a minimum width of eight (8) feet wide, installed on a compacted, six (6) inch deep, %-inch gravel road mix, on sterilized ground with weed preventive fabric; 2. StIeam Corridors. A gravel surface, a minimum width of six (6) feet wide, consisting of compacted, six (6) inch deep, %-inch gravel road mix, over a treated area with a weed preventive fabric, or an alternative trail standard subject to review and approval by the Recreation and Parks Advisory Board. SECTION F. ORIENTATION OF STRUCTURES. Commercial lots located in the Nordl 19th Avenue and West Oak Street entryway corridors shall be de- signed in a manner to eliminate negative visual impacts resulting from the orientation of accessory activi~ ties and functions common to the rear of structures (loading and unloading areas, ground mounted me- chanical equipment, storage refuse areas or outside storage areas). The rear of structures, or the activities and functions common to the rear of the structure, shall not be orientated towards the arterial streets, pedestrian or bicycle trails or common open space without proper architectural design, screening or land- scape buffeting. SECTION G. ORIENTATION OF OFF-STREET PARKING AREAS. Commercial lots located in the North 19th A,,'enue and West Oak Street entryway corridors shall be de- signed in a manner that diminishes the visual impact of expansive off-street parking areas separating build- ings from the street, by including parking areas that are beside and behind, not just in front of buildings. This would encourage the placement of buildings closer to streets and expanses of parking to be broken up. DOP UPDATE-14
