After several meetings, the subcommittee has worked through each section of the Design Guidelines and has recommended specific changes to the Guidelines. Attached to this memo is the strikethrough version of the Amended Design Guidelines. The recommended changes include: • Clarifying the main components of commercial site design that should be considered throughout the design development process; • Adding a maximum Light Reflective Value (LRV) of 60% for building color, • Adding language to the current "Building Massing" section in an effort to avoid the appearance of vertical blocks by encouraging appropriately scaled buildings through the use of segmented forms and masses. • Adding design standards for buildings located adjacent to or near pedestrian frontages. For example, building frontages and sides of buildings oriented to the street or other public areas (i.e. parks, open space, trails, or corridors) should incorporate a combination of arcades, pedestrian level displays windows, storefronts, and store entrance; • Requiring a solar study for buildings in excess of three stories located in the Town Core; and • Revising the residential fence guidelines to established review criteria for staff approvals. After two public hearings, the Planning and Zoning Commission unanimously approved Resolution 05-05 (attached) recommending approval of the Amended Residential, Commercial, and Industrial Design Review Guidelines.

Commercial and Industrial Development Guidelines The overall design theme for the Town should be emo tens iviM the dominant ehame w of a~t~ development, to establish an attractive appearance for visitors and residents, and yet be flexible enough to allow a ferdable design innovation and sehaie - The architectural styles , mesi of them ean fferibea should be contemporary, having in common, pitched roofs, stepped facades, recessed windows, balconies, and subtle eelens earthtone colors that have a maximum Light Reflective Value (LRV) not to exceed 60 (LRV). It There are a few existing buildings that have vibrant blue or red roofs, or long blank, windowless walls. These buildings are the exception rather than `the norm'. 1 ,fem. iv y kv,' .r A. Commercial and Industrial Site Development Site design Buildings and other improvements should be individually designed for the site on which they are to be placed. The site and its relationship to other structures, scenic values, views, and climatic orientation should be the dominant factors in the design'and sighting of buildings. Pedestrian access ways should be aligned and focused on architectural or A contemporary commercial building in downtown Avon. Exhibit "A" to Resolution 05-05 aesthetic features. The main components of commercial site design that should be considered throughout the design development process include: • Building, walls, roofs, ridgelines, eaves, and other architectural features • Service, loading, refuse collection areas and storage _areas • Special user amenities (i.e. pedestrian plazas, enhanced pedestrian zones) and other special features (i.e. focal architectural elements landscape features and public art) • Outdoor dining areas when food service is a component of a single or multiple tenant center) • Linkage and coordination elements with surrounding uses Requirements: 1. Site layout and proposed improvements shall consider the use of passive and active solar use, ands --on consideration of neighboring properties views eeffidefs' and solar access. Proposal should follow the local development pattern (i.e eometry of street system, open space and view corridors, common setbacks, streetscapes). The continuation of such patterns should contribute to a unified visual appearance within the area. 2. The location of structures and access shall complement the existing topography of the site. Excessive grading and/or the use of engineer-designed retaining walls are discouraged when an alternate site layout would minimize such disturbances. 3. Buildings and improvements shall be designed and sited to conform to the natural terrain and to take advantage of views. Terraced buildings and parking will minimize site disturbance, and disturbed areas should be revegetated with recommended plant species listed in Appendix 1. The use of listed noxious weeds, as provided in Appendix 2, is prohibited. aveid: al•1-"nage a-adutility -ea,ements, setbaekis, areas eve-r- 40-OA 0 300,~ 5. The use of sun exposure-reducing elements such as overhangs, pergolas, canopies, eaves and awnings should be designed as integral components of the architectural design. Passive solar design is encouraged. However within these spaces, there should be a variety of sun and shade conditions to allow full use during the extreme heat of summer months and take advantage of warm winter days. North facing entries and outdoor space such as courtyards and plazas should be carefully considered because of winter conditions. 6. Building entries should be easily identifiable and visible from the public realm. 2 Exhibit "A" to Resolution 05-05 Views 7rcrroced buildinIf Site Access Access to the building site requires consideration of topography and building orientation. Avoidance of steep slopes, the blending of access with the natural contours of a site, and sensitivity to solar orientation, are important in establishing a successful access. Where access drives connect to public streets, drainage and landscape maintenance are the responsibility of the owner. Additionally, heated driveways must not exceed the property line. Requirements: 1. Adequate distance from intersections and proper relation to other entrances. 2. Satisfactory width, grades, radii etc. as indicated in Table 1.0. 3. Turn lanes, if required by the Town Engineer, shall be designed in accordance with requirements indicated in Table 1.0. 4. Residential projects with 6 or fewer units shall be restricted to a single point of vehicle access from the public right-of-way. Additional points of access must be specifically approved by the Planning & Zoning Commission, with the finding that additional access points are required for the project to otherwise conform to these Design Standards and other applicable Town regulations. 5. The grade of the first 20 feet of driveway adjacent and perpendicular to the paved public way shall not exceed 4% grade. 6. Parking lot grades should not exceed 6% and driveway grades should not exceed 8% for multi-family residential, mixed-use, and commercial projects or 10% for small residential projects. 7. The grade of the first 20 feet of driveway adjacent to the garage or outside parking space shall not exceed 4% grade. 8. Project site plans shall include provisions for emergency vehicle access when required. 9. Adequate maneuvering for all vehicles on site must be provided. 3 Soar bxpcsLire Exhibit "A" to Resolution 05-05 10. Where buildings are required to be setback far from the street a strong pedestrian connection should be provided to the street edge to promote connectivity to transit and existing and planned pedestrian Dathways and network stops. Parking and Loading Surface parking is discouraged in the pedestrian oriented commercial areas of the Town, except for short-term use and service functions. The predominant parking functions should occur in structured parking areas for large commercial projects. The more vehicular oriented commercial core area is designated for surface parking. Requirements: 1. Required spaces provided must be in compliance with standards set forth in Section 17.24.020 of the Town of Avon Zoning Code. 2. All spaces must be accessible and meet minimum size requirements as required in Section 17.24.020 of the Town of Avon Zoning Code. 3. All parking must be off-street. Ninety-degree stalls are encouraged. Complete vehicular circulation including back-up and turn-around areas must be provided. 4. Parking areas must be concrete or asphalt with spaces clearly marked. Two handicapped stalls per each 100 stalls is recommended. Snow storage areas equaling 15% of all parking areas are recommended. 5. Driveway or maneuvering areas within a parking lot must be designed to provide for safe and reasonable maneuverability of vehicles. 6. Parking areas should include landscaping and screen surface parking. Oor w;e;, 'Onhag EX,Ih Bcemr, Landscape .

Landscaping placed in easements may be subject to removal and are the responsibility of the property owner to replace and maintain. Trees placed in drainage easements paralleling public streets may be damaged or destroyed by. Town maintenance operations. Dedicated easements shall remain unobstructed unless they are officially vacated. Site Grading Grading a property should be minimized, and only done as necessary for building improvement. Grading required in easements and setbacks is expected to be restored and revegetated to natural conditions before site construction is complete. Where finished grades require retaining wall placement, a series of lower retaining walls with landscaped terraces is preferable to a high wall with an unbroken vertical face. Requirements: Site improvements should be designed to conform with existing site topography to minimize required grading and effect on adjacent properties. All grading shall occur within the property boundaries. Both existing and finished grades are required to be clearly marked on the site plan submittal, to the extent specified on the Minimum Submittal Requirements (Appendix 3) checklist. 2. Maximum slope of disturbed slopes shall not exceed 2 feet horizontal to 1 foot vertical without special documentation and review. 3. Horizontal and vertical variations in grading cut and fill areas should resemble a natural configuration. Long slopes should be varied to avoid the appearance of flat surfaces, unless the original slope was in this configuration prior to grading. 4. Building sighting and foundation excavation shall avoid the disruption of existing natural features such as mature trees whenever possible. 5. All grading, including utility connections, is required to be shown within the proposed `site disturbance boundary' on submitted application plan sets. 6. All grading shall require erosion control methods so that dirt and fill material does not leave the property on to the public right of way and adjacent properties. A surety may be required for the proper installation and maintenance of erosion control. 7. All graded areas shall be revegetated as soon as practicable during the construction process. Dust suppression and the prevention of noxious weed infestation is the responsibility of the owner/developer. 8. Retaining walls shall be constructed of permanent type materials such as concrete, gabions, reinforced earth, etc. railroad ties are not acceptable. Retaining wall design details may be required for design review. 9. Walls over 4 feet high shall be structurally designed or certified by a licensed engineer (P.E.). Exhibit "A" to Resolution 05-05 Drainage Adequate grading plans ensure that drainage is functional on a building site. The builder is responsible for preventing erosion of the site both during construction and after the project is complete. Grading plans must adequately demonstrate positive drainage away from building structures. Requirements: 1. All drainage easements shall remain unobstructed. Drainage into common open space is not allowed except in existing natural drainage channels or drainage easements. Drainage swales should not surface drain across major walkways or trail systems. Parking bays and walkways should not slope toward the building without adequate provisions for draining storm water away from the structure. All paved areas must be sloped to drain. 2. All structures shall be located above or be protected from the 100-year floodplain, where identified by FEMA mapping. Where mapping is unavailable, the Town may require a qualified engineer to conduct an analysis of whether or not the proposed structures are proposed in a floodway or floodplain. 3. Minimum setback of thirty feet shall be maintained from mean annual high water mark of all continuously flowing streams. 4. All development shall conform to the Town of Avon Drainage Design Manual, as part of the Master Drainage Study (Sept. 1994). (Appendix 5). 5. All construction projects shall conform to the Town of Avon Pollution Control Plan Manual. (Appendix 4). Snow Removal and Storage The Town of Avon receives varying amounts of precipitation depending on aspect and elevation, typically in the form of snow. However, all sites must be able to adequately accommodate and transport snow on site in conjunction with approved drainage easements. Requirements: 1. An area equal to 20% of the total impermeable surfaced area of the site, upon which aboveground construction does not occur, shall be designated and developed as a snow storage area. 2. Designated snow storage areas shall be located and developed to be compatible with snow removal operations, not less than six (6') feet wide, and shall be adjacent to the impermeable area from which the snow is to be removed. 3. Runoff from snow storage areas shall be directed through a treatment facility as required for treatment of runoff from parking and driveway areas. 4. On-site snow storage requirements may be waived by the Planning and Zoning Commission upon the demonstration that an appropriate alternative 6 Exhibit "A" to Resolution 05-05 snow-storage site is available and that arrangements have been made for the continuation of snow removal and off-site storage. 5. Excavation, retaining walls, or other structures within slope maintenance and snow storage easements adjacent to public rights-of-way shall be confined to those strictly required for effective site access. Water and Sewer, Trash Storaize Each site design shall address the availability and design of water and sewer service, along with trash storage on the lot. Trash storage must be identified on the site plan, including design detail, for all multi-family units greater than a duplex. Requirements: 1. Each structure designed for human occupancy shall be connected with water and sewer facilities made available by existing water and sewer districts. Letters of commitment from the appropriate districts may be required. 2. No private wells or sewer systems shall be used within the Town except as provided in the Subdivision Regulations. 3. Each project shall have receptacles for the temporary storage and collection of refuse. The handling of trash for all projects larger than a single-family unit (i.e. duplex, triplex) shall be noted on the site plan. When necessary, bear resistant trash receptacles may be required. 4. All trash receptacles shall be screened from public view and protected from disturbance. 5. Refuse storage area shall be accessible by collection vehicles and should be incorporated into building design whenever possible. Non-combustible receptacles only for ash. A well-screened and attractive service and trash enclosure at the Brookside Lodge. 7 Exhibit "A" to Resolution 05-05 Sidewalks As necessary in certain commercial subdivisions and planned unit developments, the inclusion of sidewalks on a property ffmy shall be required by the Town to provide a neighborhood amenity. Requirements: 1. Sidewalks or walkways shetild shall be provided as necessary for efficient pedestrian circulation within the project and with neighboring properties. Walkways should be separated from vehicular traffic where possible. 2. Walkways should be constructed of attractive, durable materials such as decorative concrete or brick pavers. 3. Walkway widths should be compatible with anticipated uses, but in no instance, shall be less than 4' wide as a minimum standard. B. Commercial and Industrial Building Design General Commercial Design Character In addition to the stated Design Philosophy, and General Design Compatibility, buildings should be designed to maximize energy efficiency by limiting windows and doors on the north, and taking advantage of sun exposure on the south. Additionally, building design and location should generally minimize impacts on solar and view corridors of neighboring properties Building facades should be stepped to avoid long straight walls, and entrances should be recessed. All sides of buildings should receive equal architectural treatment. Windows should be placed to provide architectural interest. Large, uninterrupted glass areas should be avoided. Emphasis of building design should be prioritized with primary emphasis being placed on the first two floors, or the "base area". At the pedestrian scale, buildings should contain quality design details that are harmonious with the overall building architecture. Secondary emphasis should be placed on the top floor or "roof form" with particular attention placed on roof style, treatment, and screening. Rooftop equipment and vents;-es well as tFas h dispes°' and se should be concealed with a treatment that is complementary to the building architecture. It is preferred that buildings be designed as a composition of architectural elements rather than larger single `blocks' that appear unrelated in form and context. Building Massing: The intent of this section is to avoid the appearance of vertical blocks by encouraging the creation of appropriately scaled buildings through the use of segmented forms and masses. Building massing should serve to define entry points to buildings and help orient users. The scale and proportion of the spaces between building masses should also be given careful consideration, especially in shopping and pedestrian areas. These "public spaces" should be designed with attention given to their height, width, and length to maximize the comfort to users. These "public spaces" should include detailing that adds interest, orientation and spatial definition. 8 Exhibit "A" to Resolution 05-05 Requirements: 1. The building shall be designed as a composition of architectural elements rather than larger single blocks that appear unrelated in form and context. 2. The street level architecture shall enhance pedestrian activity and encourage a lively center of retail activity in the commercial core area where appropriate 3. Building facades shall be articulated with variations in material and punctuated with intermediate roof forms and building proiections. 4. Varying expressions of decks, windows and surface treatment shall be combined to create a rich texture that will enhance the interest of the facades. 5. The three primary building components comprising the building's base "body" and "top" shall be clearly and deliberately expressed. The building's base shall express mass and support with the use of such materials as stone and architectural concrete. The "body" of the building shall begin to transition from material that express mass to lighter material and more openings and surface variations such as decks and changes in wall plane Building Height The height of structures, unless otherwise specified in a planned unit development, shall conform to the zone district limitations stated in Title 17: Zoning Regulations. The definition of height is set forth in the `Definitions' section of these guidelines. No exceptions to the height requirements shall be made, except as specifically approved for penetrations of certain architectural projections such as flues, chimneys, cupolas, towers or other elements that may have the potential to add architectural character and variety to the skyline. Solar access is of primary importance within the town core, and commercial designs may be required to provide solar access studies showing the effect of shading on adjacent buildings and outdoor spaces (Sun studies should be prepared on a site plan of a scale not less than 1 "=40' showing shadows at 10 am and 3pm Been on March 21, June 21, September 21, and December 21). A solar study shall be required for buildings exceeding 3 stories located in the Town Core. Building Height will be determined by utilizing the site development plan and elevations. All ridge elevations, and numeric existing and proposed grades must be labeled on the site plan to accurately determine height. Additionally, the elevation plans must show existing and proposed grades (also labeled in numeric form). Building Materials and Colors The intent of these guidelines is to provide architectural control to "ensure that the architectural design of structures and their materials and colors are visually harmonious with the town's overall appearance, with surrounding development, with natural and existing landforms, and with officially approved development plans". These guidelines should represent the minimum standard to achieve this goal, without being so cumbersome as to not allow varied high-quality design that meets this intent. 9 Exhibit "A" to Resolution 05-05 Requirements: 1. The use of high quality, durable, low maintenance building materials is highly encouraged. 2. The following materials and wall finishes will not ordinarily be permitted on the exterior of any structure: asphalt siding, imitation brick, asbestos cement shingles or siding, imitation log siding or plastic. Metal siding, concrete or concrete block will be permitted only with specific approval of the Commission. Each elevation must use a minimum of two materials (i.e. stucco, siding, wood). 3. brighter- eele-s used f - aeee . All exposed exterior walls and roofs of buildings, retaining walls, and accessory structures shall be earth tone in color and shall blend in with the natural setting. Colors shall not exceed a light- reflective value (LRV) of 60 percent. 4. All flues, flashing and other reflective materials shall be painted to match and/or appropriately contrast with adjacent materials. In some cases, physical screening may be required. 5. Electric and other utility meters shall be attached to the main structure and screened to minimize contrast with adjacent materials. Roofs Roof forms are strong determinants of architectural style. Due to climatic conditions, roof forms should be kept simple, with pitches limited to 6:12 to 12:12 for sloped roofs. Flat roofs are discouraged except for limited roof areas for the location of concealed mechanical equipment, or for architectural effect. Secondary shed-type roofs should have pitches no less than 4:12. Valleys and complex roof forms are a potential source of ice buildup and water damage, and should be used carefully and sparingly. Requirements: 1. The use of dormers (shed, peaked, eyebrow, etc.) is encouraged to help break up large expanses of roof, to enhance the usability of attic spaces, and to add interest to the roof-scape. 2. Roofing materials should be durable, weather resistant and suitable for environmental conditions encountered in this area. Colors should be natural or earth tones. Large expanses of bright, reflective materials will not be acceptable. Asphalt and fiberglass composition shingles must be of high quality and minimum weight of 300 pounds per square. Untreated shakes are not permitted. 3. In the Town Core, unglazed concrete, copper, standing seam metal, or terne- coated steel are acceptable materials (Shake shingles, asphalt, and fiberglass roofs are generally discouraged). Tile should be used in a dull finish in colors. Metal roofs with a dull finish may also be considered, however colors should be muted to fit within the context. 4. All roofs, except the flat portion thereof, shall have a rise of not less than 4- inches in 12-inches of distance. 10 Exhibit "A" to Resolution 05-05 5. Pitched roofs shall be oriented such that excessive snow and ice does not accumulate over, or drop onto pedestrian walkways, parking areas or drives. Special protection may be required for roofs so oriented. Overhangs are required on pitched roofs, and shall extend at least one and one-half feet from the point where the wall meets the roof. The minimum overhang length is 18 inches for structures 3 stories or less. For structures exceeding 3 stories, the minimum overhang length shall be 36 inches. In all buildings, regardless of the height or number of stories, exterior details shall be appropriately scaled. 6. Exposed metal flashing, gutters, downspouts or other building appurtenances must be copper, steel, iron, or aluminum, applied and fastened in a high- quality manner. When painted, these elements must be finished with a baked enamel paint, epoxy paint, or a silicon-modified alloy. 7. Snow shedding is a major concern that must be carefully considered in the designing roofs. Building entries, garage and service doors, shop fronts, and other points of entry must be located out of the path of shedding snow. Gable fronts, covered porches, balconies, and snow retention devices are all acceptable methods of dealing with snow shedding off of sloped roofs. Landscape features such as retaining walls or raised planters may also be used to direct pedestrians out of the way of snow or ice shed areas. Where removal of snow from roofs is anticipated, mechanical and safety devices should be provided, as well as easy access to the roof. 8. Roofs shall be varied to avoid uninterrupted flat roofs. 9. Roofs shall be proportional to the height and scale of the various building elevations. The primary roof(s) and upper portion of the walls shall be articulated so as to minimize their visual impact on surrounding properties which may include such measures as the introduction of decks and the lowering of rooflines. 11 Exhibit "A" to Resolution 05-05 Interesting roof forms add character, such as those found in the Westgate PUD. Exterior Walls The form of exterior walls in the commercial areas of the Town should grow out of a balanced response between the public spaces they front and the interior functions they enclose. Walls can be broken down in scale through the use of windows, doorways, recesses and setbacks. They should be further articulated through the use of different materials, patterns, ornament, texture, and color. Walls should also respond to solar exposure in their placement. Exterior walls should attempt to enclose exterior space and to create a sense of `street'. This encourages the linkage of one building to the rest, and the continuation of urban form as opposed to individual buildings in the landscape. Requirements: 1. Stucco and synthetic stucco are suitable on upper walls of buildings. Joints, variety or color, and changes in plan should create a sense of scale on stucco walls. 2. Stone elements should be used when appropriate on the base of larger buildings, up the walls, or in elements such as chimneys or towers. Roughly squared stone set in a random pattern is preferable to more formal uses of stone. In large walls, stone should be set with larger stones at the bottom gradually diminishing to smaller stones at the top. 3. Projections such as deep eaves, overhangs, canopies, and other features that provide architectural interest are encouraged. Fenestration should be articulated on large exterior walls to break up massing. At a minimum, no single wall plane should exceed 70% of the elevation of any exposure. Breaks in the wall plane should form at least a 2-foot step/setback. 4. Wood siding should be avoided in commercial building where it will be in contact with snow (at the base). The scale of wood siding (4", 6", 811, or 12 Exhibit "A" to Resolution 05-05 larger) should be appropriate and complement the desired design of an exterior wall space. 5. Exterior elements such as porches, roof overhangs, dormers, and gables should utilize heavy timber when appropriate to create interest, give scale, and signify areas of architectural importance. 6. Building facades will be stepped to avoid long straight walls. All sides of the building must receive equal architectural treatment. Design of Pedestrian Frontages Building frontages and sides of buildings oriented to the street or other public areas (i.e. parks, open space, trails, or corridors) should incorporate a combination of arcades, pedestrian level displays windows, storefronts, and store entrances. To activate the building frontage, entrances should be located at intervals at a maximum of 50 feet. Building frontages should exhibit human scale detail, windows and other openings along ground floor pedestrian areas. Windows Windows establish patterns, rhythms, and scale on the exterior walls. They respond to uses and needs on the interior and are recognizable indications of what goes on behind them. Variety in the use of windows is encouraged within certain limits. Commercial spaces must have large areas of glass opening onto public pathways, streets, or sidewalks (suggested goal is 75% glass). Hotels and other private uses should have more limited use of glass. In all cases, large uninterrupted areas of glass are discouraged. Division of windows by mullions and muntins adds character and gives scale to the building. Requirements: Aluminum, steel, painted wood, or clad wood windows are permitted in all commercial areas. Mirrored glass, snap-in muntins, glass curtain walls, and other assemblies which are clearly out of character with the Town Core are prohibited. 2. Pedestrian level windows in commercial spaces require a minimum allowable glass area of 75% of walls opening on to the ground/pedestrian level. The maximum size of individual panes of glass is not to exceed 16 square feet without special review. In general, areas of glass unbroken by wall or structure should not exceed 150 square feet. 3. Pedestrian level windows in hotel or office spaces should be as open as possible and not less than 50% glass, unless it is a north exposure, in which case glass may be reduced to 40%. The same restrictions apply to sizes of individual panes and areas of glass unbroken by wall or structure. 4. All upper levels of commercial, hotel, and/or office area have no requirements for percentage of window to wall, but are restricted to individual panes of a maximum of 10 square feet and a maximum overall glass area of 48 square feet per window opening. 13 Exhibit "A" to Resolution 05-05 Windows Y71-M-11 16 69 JN4)i to Doors and Entryways Public doors and entryways within the Town should be a combination of glass and metal or wood, or solid wood. All-glass or all-metal doors are discouraged. Doors should be used to establish interest, character, and variety along the public right-of-way. Where possible, gates, courtyards, staircases, and bridges should be used to connect building sand create outdoor rooms and linkages. Service doors may be hollow metal or solid wood in hollow metal frames. Main entries should not be placed on the north side of buildings unless no other alternative exists. When a main entry occurs on a north fagade it should be covered with a porch or porte cochere. 14 a r&I ;.T , ! W7 in wall Exhibit "A" to Resolution 05-05 Lborw?~ S E:I= "Z: ! !i L7 ! 'X ' n► - `44 Decks and Balconies and Exterior Walkways Decks and Balconies become part of the design palette used to enrich the character and create variety on the building exteriors. Where possible, balconies and decks should be located to take advantage of solar exposure, and should be used in combination with bay windows and other exterior projections. Long, linear balconies such as might appear on a common motel are discouraged in the Town. Care should also be taken in locating walkways to avoid placing them in areas which are in shadow all winter long. On the north side of buildings, sidewalks should either be covered or far enough away from the building to be out of its shadow for several hours each day. 15 Exhibit "A" to Resolution 05-05 This Outdoor Lighting Lighting systems will serve functional and aesthetic roles in commercial areas. These roles are: to provide security and visual safety, to serve as directional indicators for both vehicular and pedestrian traffic; to provide extended outdoor use time, particularly in pedestrian gathering areas; and to reinforce the identity and character of a project through form, color and materials of fixtures, visual light quality, and placement. Access to a clear and visible night sky is .a strong value to our community. Night lighting on a site sheald gene must be regulated to minimize the undesirable effects that `over-lighting' a site can have on a community, neighbors, and guests. At the same time, lighting is desirable for safety and aesthetic purposes. In all instances, outdoor lighting must comply with Chapter 15.30 of the Municipal Code. Requirements: 1. Lighting should be provided for all parking, drive, and walkway areas and may be required as a condition of design approval. In all commercial, retail and office parcels, lighting must be designed and arranged so as not to reflect excessive light upon abutting or adjacent properties. . 2. Lighting should be considered as a design feature as well as providing illumination. Area lighting shall generally be a metal halide, cut-off type fixtures with a maximum mounting height of 15 feet for walkways and 25 feet for parking areas. There shall be no exposed light source on a property, and all fixtures must utilize frosted or seeded glass. 3. Pedestrian areas should utilize low-level light sources to accent or illuminate the ground plane. These design elements should provide light for safety and aesthetic 16 Exhibit "A" to Resolution 05-05 effect. By day, the physical shapes and sizes lend animation and scale to pedestrian spaces. 4. Lights which flash, move, revolve, rotate, flicker, blink, or vary in both intensity and color to emit intermittent pulsation shall be expressly prohibited as fixed light sources. This does not include holiday/seasonal lighting, which is temporary in nature for the holiday/season, from November 15`h to March 1St C. Commercial and Industrial Landscaping Design Character Landscaping in Commercial and Industrial areas of the Town must recognize the drought conditions that prevail in our western region, and be tolerant of these drought episodes. Plant material selection and placement must ensure safe sight lines to traffic and signs. Care should be taken that no hazards are created for pedestrians and vehicles by plant litter. Trees and shrubs with thorns should not be used in or near pedestrian areas. All landscape development for commercial projects, including specific landscaping elements such as planters, retaining walls and berms must be specifically approved. Landscaping should accentuate a project design, not hide it from public view. Landscaping must meet minimum zoning requirements; however, only 20% of the total landscaped area may be irrigated. Irrigated areas must be delineated on all plans. Requirements: 1. Landscaping must be designed to incorporate water conserving materials and. techniques through the application of seven fundamental xeriscape landscaping principles including: a. Planning and designing a landscaped area that groups plants with similar water and sunlight requirements together. b. Creating practical and appropriate turf areas (when necessary), utilizing a lower water-use turf such as buffalograss, blue grama, or turf type tall fescues and fine fescues. c. Use of low water demanding plants and dryland seed grass mixes. d. Use of automatic irrigation systems, designed and operated to conserve water by applying the right amount of water at the right time. e. Incorporation of soil amendments, where appropriate for the site and type of plants proposed. f. Use of Mulches, such as woodchips, to reduce evaporation potential and keep the soil cool. g. Planting appropriate materials suited to the soil and climate, and appropriately maintaining the vegetation once established. 2. Preserve and protect as much existing vegetation as possible. Incorporate existing trees when locating structures. 3. Consideration should be given to use of landscape material for snow fencing, visual screening and wind breaks when applicable. Hedges, in winter, become snow fences and must be placed accordingly. 17 Exhibit "A" to Resolution 05-05 4. Plant materials should be adaptable to the area and selection and placement should include consideration of function and color coordination. Proposed materials must be called out on plans. A list of recommended plant species that are compatible with various climate zones found in the Town is attached in Appendix I No noxious weeds, as listed in Appendix 2, shall be permitted for use in the Town. Irrigation/Watering Requirements: 1. The landscaping site plan must identify the area of approximate installation of an automatic irrigation system, its maintenance, and intended uses. All landscape plans must note and delineate all irrigated and sod areas. 2. A rain sensor must be installed with each new irrigation system, in order to interrupt irrigation in the event of a significant rainfall. Inspection for the rain sensor will be conducted prior to issuance of a Certificate of Occupancy. 3. The followina table must be provided on all landscape plans: Landscape Area Provided % of Lot / Square Footage Total Irrigated Area % of Landscaped Area / Square Footage Spray Area % of Irrigated Area / Square Footage Drip Area % of Irrigated Area / Square Footage Sod Area % of Irrigated Area / Square Footage 4. All irrigation shall be subject to the watering schedule as imposed by the Eagle River Water and Sanitation District (ERWSD). 5. Temporary (overhead) sprinkler irrigation is allowed to re-establish native vegetation and seed mixes on otherwise non-irrigated portions of the landscaped areas, however, must be removed 1 year after installation. All disturbed areas will be adequately reseeded and restored on all projects. Turf Requirements: 1. The following types of ornamental grasses are recommended: Buffalo grass, Blue Grama, Little Bluestem, Smooth Brome, Crested Wheatgrass or Western Wheatgrass. 2. In all disturbed areas, soil must be prepared with the addition of organic matter, and tilling the soil as deep as possible. The addition of decomposed organic matter (compost, composed horse manure, or composted chopped straw or hay) is required for turf installation. 18 Exhibit "A" to Resolution 05-05 Well placed landscaping on a commercial projects accentuates the project features. Fencing and Screening All commercial service areas are to be screened from adjacent land uses by architectural features such as solid four-foot or six-foot fences, and/or heavily massed plant materials. All fences, whether decorative or for screening must be constructed of wood; masonry walls will only be considered if they are designed as an integral component of the building's architecture. Buffering may be required by architectural features if excessive noise levels are anticipated or encountered. Requirements: 1. Loading and unloading facilities must be separated from employee, customer and visitor circulation and parking areas wherever feasible. All service areas, loading and unloading docks must be screened from public view. 2. Ground-mounted equipment such as power transformers and air handling equipment must be screened from public view by either materials integral with the building, a fence or landscaping, all of which must be specifically approved for the site. Trash dumpsters shall be screened by a six-foot fence or wall similar in character to the adjacent structure, with access gates as necessary. 3. Fence materials shall be compatible with the site and the materials of the structures on the site. Fencing may be used in combination with plant materials. In all cases, however, plant materials must be used to screen utility boxes. Meters, phone pedestals, and transformers will occur to the side and rear of the building whenever possible and be appropriately screened. 19 Exhibit "A" to Resolution 05-05 4. No wall, fence, or planter in excess of two-feet in height should be constructed or maintained nearer to the front lot line than the front building setback line. No front, side or rear fence, wall or hedge may be more than six- feet in height. 5. Fences should be either one of three types in commercial areas: two (split) rail open fences, four-foot solid fence, or a six-foot solid fence. No chain-link permitted. -.Twol~~+1 DPI" Erosion Control Erosion control is essential at all building sites. Design plans must indicate the type, method, and placement of erosion control structures on the property. A surety may be required to ensure proper installation and maintenance of these items. All commercial projects will need to reference the Avon Master Drainage Study, available in the Community Development Department for minimum requirements. Retaining Walls The limited use of retaining walls is encouraged. Whenever possible, retaining walls should be utilized only in those areas of a site where finished grades cannot meet recommended standards. Small retaining walls using natural stone boulders are encouraged for use and design with site landscaping. Requirements: 1. Retaining walls shall be constructed of permanent type materials such as concrete, gabions, reinforced earth, etc. railroad ties are not acceptable. Retaining wall design details may be required for design review. 2. Walls over 4 feet high shall be structurally designed or certified by a licensed engineer (P.E.). A series of lower retaining walls with landscaped terraces is preferable to a high wall with an unbroken vertical face. 20 Exhibit "A" to Resolution 05-05 D. Commercial and Industrial Miscellaneous Items Accessory Structures Requirements: 1. Temporary structures including construction storage and office trailers, and tents shall not be allowed except as may be determined to be necessary during construction. 2. Permits for allowed temporary structures may be issued by the Community Development Department as a minor modification/minor project without review by the Commission. Permits shall run concurrent with building permit. 3. Any accessory structures on the building site shall be compatible with the design and materials utilized for the main building structure. Permits for accessory structures may be issued by the Community Development Department as a minor modification/minor project without review by the Commission. 4. Accessory structures must be shown on the final design site plan, and should generally be attached to the main building. The method of attachment should be generally compatible with the overall architectural design. Sins Well-designed and constructed signs attract attention, create a sense of quality and contribute to the overall urban character of the Town. In general, all signs must conform to the Town of Avon sign code unless otherwise conforming to another approved Master Sign Program. All building mounted signs should be located on a fascia or architectural detail designed for such purposes. Freestanding identification signs should reflect the architectural character of the building. Flush mounted signs are encouraged with projecting signs allowed to any adjacent walkway or pedestrian mall. Requirements: 1. No signs, billboards, or other advertising of any kind shall be erected constructed, or maintained on any lot or structure unless approved in accordance with the provisions contained in the Sign Code of the Town of Avon (Section 15.28.00). Communications & Satellite Dish Antennae Satellite dishes are permitted in commercial areas, however, with restrictions on screening these dishes from neighboring properties and prominent views. Screening may be accomplished through the placement on a building, however, a separately built fence/screen may not be used. Requirements: 1. All antennas shall be located so as to be screened from view from any public right-of-way or neighboring property. Screening may be accomplished by, or through the use of landscaping materials, existing structures, sub-grade placements or other means that both screen the antennas and appear natural to the site. 2. All wiring and cable related to antennas installation shall be installed underground or be incorporated entirely within the structure. 21 Exhibit "A" to Resolution 05-05 3. Color selection for dish antennas should blend with the site and structure. Unpainted surfaces and dish antennas with reflective surfaces shall not be allowed, and surfaces are required to be painted to match adjacent trim surfaces. No advertising, logos or identification shall be allowed on any dish antenna. Above Ground Tanks and Miscellaneous Structures Requirements: 1. Oil, gasoline or liquid petroleum gas tanks will not normally be permitted on or above ground. Temporary installations for a period not exceeding 2 years may be approved provided the installation complies with all applicable regulations and is fully screened from view from all public rights-of-way and neighboring properties. 2. No outdoor clotheslines, trash receptacles, or storage areas will be permitted unless screened. 3. Screening details shall be reviewed and approved by the Commission prior to installation. 4. Flues, vents, chimneys, and other mechanical penetrations of a roof on any structure shall be fully enclosed and screened in such a manner as to conform with the overall design character, and equipped with spark arrestors. 22 Exhibit "A° to Resolution 05-05 Fencing and Screening All fences require approval through a `Minor Project and/or Modification' application. In all instances fences should compliment the property and landscape Feg is rather than contain the property. Fences that delineate property boundaries are not permitted. Fences will be considered for approval by staff only when demonstrated by the applicant that the design is consistent with the following criteria: Requir-ementsi e ~aco -arv+v+v~ua uav 1.
