Purpose and Intent Design Philosophy The general design philosophy for the Town of Avon is to preserve and protect property values by creating an aesthetic quality throughout the built environment of our community. The Town should continue to be perceived as a contemporary mountain town, complementary to the natural landscape and unbuilt environs. The Town should appear as a cohesive unit comprised of simple building forms, subdued colors, and predominantly pitched roofs. In residential areas, the relationship between buildings and the natural environment should be harmonized rather than dominating. Landscaping should blend the surrounding natural environment and the home, not hide one from the other. Form, scale, proportion, and materials should support the natural environs and reinforce those characteristics that uniquely identify a neighborhood's built environ as it relates to the Town.

Residential Development Guidelines General Design Compatibility All design shall be compatible with existing built structures, the immediate unbuilt environment, and the design philosophy of the Town. It should not be inferred from these guidelines that all buildings are expected to have similar design. The overall objective of these guidelines is allow flexibility so that individual building sites can directly respond to the topography and unique features of the natural unbuilt environment. Buildings should be treated as an integral part of the site, rather than separate objects at odds with their surroundings. However, compatibility should be achieved through the use and proper consideration of the guideline criteria contained herein. On the Eagle River at Eaglebend, Filing No. 1. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 10 Adopted November 6, 2001 A. Residential Site Development Site design Site design and layout is critical to appropriate architectural development of a structure and its supporting improvements to the property. Buildings should blend in with natural settings, be stepped in appearance where practical, and be limited in the need for extensive site grading and slope retention. Buildings should be compatible with the site, and not appear to intrude or project from a lot with no relation to the surrounding landforms. Requirements: 1. Site layout and proposed improvements shall consider the use of passive and active solar use. 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 is discouraged when an alternate site layout would minimize such disturbances. 3. Removal of vegetation, trees, and other significant landforms on a site will be limited and not extend beyond a demarcated site disturbance area identified on submitted plans. The identification and removal of noxious non - native vegetation and replacement with native vegetation shall be encouraged on properties regardless of where they exist on site (ie. outside site disturbance area). 4. All 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. 5. Where no development has been identified, construction shall at a minimum avoid: all drainage and utility easements, development setbacks, areas over 30% in slope, and unique and sensitive natural site features. 6. Buildings on sloping lots shall be designed to step with the existing (natural) grades. 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 11 Adopted November 6, 2001 6. Parking lot grades should not exceed 6% and driveway grades should not exceed 8% for multi - family residential 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 by Code or local emergency service provider. 9. Adequate maneuvering for vehicles on site must be provided. Parking and Loadinli Parking and loading location and design is significant in avoiding conflict in multi - family projects, and avoiding the potential of regular on- street parking in all neighborhoods. The intent of parking and loading design on site is to provide residents and guests suitable parking locations that are also durable and functional. Requirements: 1. Required spaces provided must be in compliance with standards set forth in the `Access, Parking, and Engineering Standards' Table 1.0. 2. All spaces must be accessible and meet minimum size requirements as outlined in the `Access, Parking, and Engineering Standards' Table 1.0. 3. Residential loading spaces properly located to function with improvements and accessible to delivery vehicles without restricting street traffic or on -site circulation. 4. Pavement design must be compatible with proposed use. All parking surfaces shall be asphalt, concrete, concrete pavers, or another impervious surface. Gravel is not an acceptable material. Easements Disturbance in drainage and utility easements should be avoided. 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. Requirements: 1. Dedicated easements shall remain unobstructed unless they are officially vacated. 2. Landscaping improvements shall avoid placement in easements whenever possible. Any landscaping improvements placed in easements shall be the responsibility of the property owner to maintain and replace should they be damaged or destroyed by the Town while doing drainage, snowplowing, or utility work. 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: 1. 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 Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 12 Adopted November 6, 2001 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 siting and foundation excavation shall avoid the disruption of existing natural features such as mature trees whenever possible. 5. All grading, including utility connection, 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 developer. A well -sited home requires less extensive grading and creates a more natural `stepped' appearance on a slope, such as this home at Eaglebend, Filing 1. Drainage Adequate grading plans ensure that drainage is functional on a building site. Drainage easements must remain substantially unobstructed to accommodate drainage from a building site. Grading plans must adequately demonstrate positive drainage away from building structures. Requirements: 1. All drainage easements shall remain unobstructed. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 13 Adopted November 6, 2001 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 and 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 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 Storage 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 duplex (ie. 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 14 Adopted November 6, 2001 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. Sidewalks As necessary in certain subdivisions and planned unit developments, the inclusion of sidewalks on a property may be required by the Town to provide a neighborhood amenity. Requirements: 1. Sidewalks or walkways should 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 15 Adopted November 6, 2001 B. Residential Buildina Desian General Design Character In addition to the stated Design Philosophy, and General Design Compatibility, a residential building must conform to setback, building area ratios, and height limitations of the applicable zone district. Buildings should be oriented to take advantage of solar gain and view corridors, where possible. Additionally, building design and location should generally minimize impacts on solar and view corridors of neighboring properties. It is preferred that residential buildings be designed as a composition of mass elements rather than larger single `blocks' that appear unrelated in form and context. 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 for penetrations that add architectural variety such as flues, chimneys, cupolas, etc. A". , MC�4f1$frD FPo� �� . - MORP RVWCTWO Gw.U-_ -' 8Inti 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), such as the illustration above. 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. Requirements: 1. The use of high quality, durable 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 building must use a minimum of two materials. 3. Indigenous natural or earth tones required. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 16 Adopted November 6, 2001 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. Exterior Walls, Roofs and Architectural Interest The Town of Avon is not comprised of a singular and unified `neighborhood' theme, however, it does contain several architecturally distinct neighborhoods. Within these neighborhoods exist a variety of exterior wall types that typify the type of design that is appropriate to our community. Requirements: 1. Exterior wall colors should be compatible with the site and surrounding buildings. The appropriate use of predominantly indigenous building materials such as native stone, wood siding, and timbers is encouraged in our mountain community. 2. 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. 3. All roofs, except the flat portion thereof, shall have a rise of not less than 4- inches in 12- inches of distance. Primary roofs shall have a 4:12 minimum, and a 12:12 maximum. Secondary roofs shall have a 4:12 minimum, and metal roofs shall have a 3:12 minimum. There shall be no unbroken ridgelines allowed, except on pueblo roofs that are otherwise traditionally articulated. 4. 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. 5. 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, however, metal such as copper, cor -ten may 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.

Outdoor Lighting Access to a clear and visible night sky is a strong value to our community. Light pollution is a threat to our clear skies that are part of the heritage of the Rocky Mountain West. Night lighting on a site should generally be regulated to minimize the undesirable effects that `over- lighting' a site or residence can have on a community, neighbors, and guests. At the same time, lighting is desirable for safety and aesthetic purposes. Requirements: 1. Lighting should be considered as a design feature as well as providing illumination for aesthetic and safety purposes only. There shall be no exposed light source on a property, and all fixtures must utilize frosted or seeded glass. In any case, light fixtures shall not cause glare beyond the property. 2. Floodlights are not permitted. Light spillover to adjacent properties must be minimized. No exposed bulbs are permitted. 3. Lights that 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. Duplex Developments Duplex developments must be designed in a manner that creates an integrated structure on the site. Two single- family residences `bridged' by a breezeway or other non - structural and non - habitable connection does not meet the intent of a duplex design. Unified design shall include, but not be limited to, the use of compatible building materials, architectural style, scale, massing, detail, roof forms, and landscaping. While `mirror image' duplexes are not supported, the design intent should be one that creates a unified structure with enough variety and architectural interest to distinguish a duplex from a single family home. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 18 Adopted November 6, 2001 C. Residential Landscapin Design Character Landscaping should harmonize the building site with both the natural topography and existing vegetation. All materials used should be indigenous to an area, represented by adjacent properties, and not contain any noxious weeds or undesirable exotic plants. Requirements: 1. Landscaping design should be compatible with other site improvements and with neighboring properties. 2. Not less than 50% of the useable open space area required, shall consist of pervious landscaped areas. The remaining useable open space requirements may be satisfied by impervious patio or mall type areas containing seating, decorative fountains, planters, recreational amenities and similar type facilities. 3. Consideration should be given to use of landscape material for snow fencing, visual screening and wind breaks when applicable. 4. Plant materials should be adaptable to the area and selection and placement should include Consideration of function and color coordination. A list of recommended plant species that are compatible with various climate zones found in the Town is attached in Appendix 1. No noxious weeds, as listed in Appendix 2, shall be permitted for use in the Town. 5. All lots to be covered by grass lawns shall utilize healthy sod material for complete coverage. All grass sod shall extend to the property line or, where adjacent to a roadway, to the bottom of adjacent drainage ditch or back of curb, as applicable. Fire Resistant landscaping in areas with wildfires is required. 6. An automatic irrigation system is required to reduce losses and for ease of maintenance. The landscaping site plan must include, at a minimum, a note regarding the proper installation of an automatic irrigation system, its maintenance, and intended use. Good landscaping that utilizes native vegetation should accentuate, not hide the structure. Wildridge. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 19 Adopted November 6, 2001 Fencing and Screening Fencing is discouraged, and will only be permitted where it complements the character of the property, existing grades and landforms, and compliments the landscaping rather than contain the property. Fences that delineate property boundaries are not permitted. Requirements: 1. Fences, walls, or similar type barriers shall have a separate approval of the Commission, except that functional or decorative fences or walls may be approved as an integral part of a building and landscaping design. Wood fences are generally more acceptable than metal. Limited use of fences, such as to screen trash areas and utility equipment, is encouraged. 2. Fence materials shall be compatible with the site and the materials of the structures on the site. No chain link fences shall be permitted in residential areas, except for use as a temporary construction fences or for use in public recreational facilities. The use of chicken wire, or metal screening, with split rail fencing is discouraged. However, should the fencing comply with the requirements of this section, the fenced area must be less than 1/4 of the perimeter of the property and no more than 4 feet in height. 3. Where noted by the Colorado Division of Wildlife (CDOW), accepted wildlife corridors shall be accommodated to a reasonable degree on all properties when considering the layout of site disturbances. Fencing should not delineate property lines. This type offencing is no longer acceptable. 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. Required erosion control techniques and Best Management Practices (BMP's) for small residential projects are listed in the Pollution Control Plan (Appendix 4). All other projects will need to reference the Avon Master Drainage Study, available in the Community Development Department. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 20 Adopted November 6, 2001 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 (6x6 treated timbers) 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.). 3. A series of lower retaining walls with landscaped terraces is preferable to a high wall with an unbroken vertical face.

Residential 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. Non - attached accessory structures are discouraged from placement on the front and sides of the building. Signs 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 residential areas, however, with restrictions on screening these dishes from neighboring properties. 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. 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 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.

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 to the overall design character, and equipped with spark arrestors. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 23 Adopted November 6, 2001 5. Commercial and Industrial Development Guidelines The overall design theme for the Town should be consistent with the dominant character of existing development, to establish and attractive appearance for visitors and residents, and yet be flexible enough to allow affordable design solutions. The architectural styles of the existing buildings vary greatly. However, most of them can be described as contemporary, having in common, pitched roofs, stepped facades, recessed windows, balconies, and subtle colors (gray, cream, tan and brown). In contrast, there are a few buildings that have vibrant blue or red roofs, or long blank, windowless walls. These buildings are the exception rather than `the norm'. A contemporary commercial building in downtown Avon. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 24 Adopted November 6, 2001 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 aesthetic features. Requirements: 1. Site layout and proposed improvements shall consider the use of passive and active solar use, and the retention of neighboring properties `view corridors'. 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 is 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. 4. Where no development has been identified, construction shall at a minimum avoid: all drainage and utility easements, development setbacks, areas over 40% in slope, and unique and sensitive natural site features. 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.

Commercial and Industrial Building Desiqn 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. At the pedestrian scale, buildings should contain quality design details that are harmonious with the overall building architecture. Rooftop equipment and vents, as well as trash disposal and service areas, 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 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 noon on March 21, June 21, September 21, and December 21). 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), such as the illustration above. 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. 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. Natural or earth tones are encouraged as the dominant color with brighter colors used for accent. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 31 Adopted November 6, 2001 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. 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. Minimum overhang length is 18 inches. 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 32 Adopted November 6, 2001 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 ", 8 ", or 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 33 Adopted November 6, 2001 6. Poured -in -place or pre -cast concrete may be used where appropriate as column and spandrel covers. At grade or poured -in -place walls with large stone aggregate are examples that may be acceptable use of concrete in some commercial structures. 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: 1. 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. 1 W(/ 7r i f- .. own" !n Wes/ Wi'ndow5 Doors and Entryways J � AaX m 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 34 Adopted November 6, 2001 L800,wa yS 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. 7"hls Outdoor Lighting & A/S 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 should generally 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 35 Adopted November 6, 2001 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. Floodlights are not permitted. 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 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 36 Adopted November 6, 2001 C. Commercial and Industrial Landscapin Design Character 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. Requirements: 1. Landscaping design should be compatible with other site improvements and with neighboring properties. 2. Trees should be massed or grouped together whenever possible to provide a greater visual impact. Tree plantings may not interfere with utility or drainage easements, and their location should be based on a function such as screening, shade, view enframement or accent. Accent plantings should occur at locations such as building entries, parcel entries, or pedestrian areas. Evergreen locations should consider shading sidewalks in winter to avoid creating hazardous icing conditions, as well as avoiding south facing windows that may be impaired to solar access. 3. Not less than 50% of the useable open space area required, shall consist of pervious landscaped areas. The remaining useable open space requirements may be satisfied by impervious patio or mall type areas containing seating, decorative fountains, planters, recreational amenities and similar type facilities. 4. 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. 5. Plant materials should be adaptable to the area and selection and placement should include Consideration of function and color coordination. A list of recommended plant species that are compatible with various climate zones found in the Town is attached in Appendix 1. No noxious weeds, as listed in Appendix 2, shall be permitted for use in the Town. 6. Grasses should be used close to pedestrian areas where visual relief from extensive pavement is desired, or, in large open areas as a soils stabilizing agent for visual effect (primarily viewed from vehicular traffic). All grass sod shall extend to the property line or, where adjacent to a roadway, to the bottom of adjacent drainage ditches or back of curb, as applicable. Fire Resistant landscaping in areas with wildfires are required. 7. In large open areas numerous grass mixes should be considered depending on water requirements and availability, maintenance requirements, potential fire hazard of dry grass, and visual effect desired. In these areas, rough grass mixes should be utilized. Native grasses and wildflower mixes require less water, less mowing and lend themselves well to the perimeter areas of the Town Center blending into the existing vegetation. An automatic irrigation system is required to reduce losses and for ease of maintenance. The landscaping site plan must include, at a minimum, a note regarding the proper installation of an automatic irrigation system, its maintenance, and intended use. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 37 Adopted November 6, 2001 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. 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.

IV TWO FairOren Erosion Control 11114fllllllllllll {IfAlllilllll� � �Iillllll IIIlllllll� �'IIIIIIIIIIIiIIIIIIIUUINIII 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 39 Adopted November 6, 2001 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. Signs 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. 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 40 Adopted November 6, 2001 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. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 41 Adopted November 6, 2001 6. Application and Processing Submittal and Review Process The Design Review process is broken down into three distinct tiers: Pre - application Meeting, Sketch Plan Review, and Final Design Review. Community Development shall review all material submitted for either of the three design review tiers to determine whether an applicant has met the minimum submittal requirements prior to the scheduling of a meeting or public hearing. Minimum submittal requirements are attached as a `checklist' for each required application, and should be reviewed carefully.

Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 44 Adopted November 6, 2001 Basis for approval or denial of project design If the design of any project is found to comply with the purposes prescribed in these Guidelines, Regulations, and any applicable Ordinances of the Town of Avon, and the design guidelines review criteria prescribed in Section 7 of these Regulations, the Planning and Zoning Commission shall approve the project. If the Commission determines that a conflict exists with the purposes, the design guidelines, or any other provision of those Regulations or any Ordinance of the Town of Avon, which would prevent approval of such project, the Commission shall disapprove the project. If the Commission determines that conflicts exist which are subject to correction, the Commission may conditionally approve or request changes to conform with the design guidelines or other provisions of those regulations. Any disapproval, conditional approval or request for changes shall be in writing and shall specifically describe the purpose, statement, or design guidelines with which the design of the project does not comply and the manner of noncompliance. Notification of an application decision shall be made by the recording secretary and transmitted in writing to the applicant within 7 days of said meeting. Compliance Deposit At such time as the Final Design Plan is approved by the Planning and Zoning Commission, and before a building permit is issued for the same project, a compliance deposit shall be required to be deposited with the Town of Avon to provide security for the Owner's full and binding performance to the approved Final Design Plan. The amount of the compliance deposit shall be equal to either: 1) Two percent (2 %) of the valuation cost of construction as submitted in the building permit application, or, 2) A minimum of $5,000 dollars. Additionally, the compliance deposit shall be submitted as cash, certified check, or letter of credit. Time limitations The time limitations contained in these Regulations shall be interpreted as requiring the Commission to conduct a review or make the determinations or decisions required by these Regulations. Failure of the Commission to act within the prescribed time limitations shall be considered as conditional approval for design of the project subject to conformance with all applicable rules and regulations of the Town of Avon. Scheduling The length of the development review process from the acceptance of a complete application by Staff to the actual hearing, shall provide the Town with a minimum review time of 21 working days. Scheduling requirements, timelines, and commitment goals are available in the office of Community Development, and may be updated periodically. A `fast track' review process is available to those plans that are determined by the Community Development Staff to be in compliance with the Town's development standards at the pre - application meeting.

Drainage systems shall be designed to protect public and private property, minimize maintenance costs and preserve the appearance of roadways and property. This manual outlines the basic engineering procedures to be used to design and construct stormwater structures and systems. Designers should use this section as a guideline when preparing drainage plans and reports for the Town of Avon. If designers feel that the methods outlined in this section are not applicable, another method may be used if approved by the Town. Design Standards — Runoff Drainage structures and facilities in the Town of Avon shall be designed to handle the 25 -year rainfall storm event. Facilities shall also be designed so there will be no major structural damage or loss of life from the 100 -year storm event. Drainage structures beneath or adjacent to arterial (i.e. I -70 and U.S. Highway 6) and collector streets (i.e. Beaver Creek Blvd., Nottingham, Avon and Metcalf Roads) shall be designed for the 100 -year rainfall event. Developers of lots adjacent to the Metcalf Gulch, Buck Creek and Swift Gulch (see plan sheets) drainage pathways are required to maintain the drainage pathway to pass the 100 -year storm. The Town of Avon may require additional drainage requirements for any site which it believes has special conditions. Snow Melt The addition of snow melt runoff is required for stormwater control only. The 25 -year snow melt runoff event shall be used. All other drainage designs can disregard the addition of runoff from snow melt. Stormwater Control A stormwater control plan and facility is required for sites with: 1. 25,000 square feet of impervious surface, or 2. Having fifty or more surface parking spaces. Sites shall be designed so the 25 -year developed flow rates do not exceed the historic. Detention facilities should be designed for the major and minor storm event. The major event will be the 100 - year storm and the minor event is the 25 -year storm. The facility shall be sized to store volume created from the difference in historic and developed 25 -year storm event. The release rate from the facility shall not exceed the 25 -year historic flow rate. The facility shall have an emergency spillway or additional outlet for the 100 -year storm. Estimating Runoff Several methods are available for estimating runoff. Designers should select a method based on the size of the drainage area and the output information desired. The Town of Avon will accept the following methods: 1. Rational Method (sites less than 5 acres) 2. Technical Release 55 (TR -55) Another method may be used provided it is approved in advance by the Town of Avon. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 60 Adopted November 6, 2001 Rational Method The rational method may be used to size storm sewers, channels, and other drainage structures which handle runoff from drainage areas less than 5 acres. This method should not be used for routing stormwater through a basin or for developing a runoff hydrograph. Drainage basin characteristics should be fairly homogeneous. Figure 3 -1 illustrates the rainfall intensity- duration curve to be used in the Town of Avon. Technical Release 55 (TR -55) TR -55 (210- VI -55, Second Edition, June 1986) is a method developed by the USDA -Soil Conservation Service to estimate runoff. The Soil Conservation Service has supplemented the TR -55 manual for Colorado to handle its unique drainage conditions. "Procedures for Determining Peak Flows in Colorado" is in the SCS manual to be used when estimating runoff with TR -55 in Colorado. There are two methods discussed in TR -55, Peak Discharge and Tabular. Designers need to decide which method is the most appropriate. The Peak Discharge Method is usually used for small homogenous watersheds and the Tabular Method is used when a watershed is divided into subareas and a hydrograph is needed. Twenty -four (24) hour rainfall amounts to be used in Worksheet 2 of TR -55 are listed in Table 3 -1.

This coefficient is needed only for stormwater control facilities. Stormwater Control Stormwater control is required for sites with 25,000 square feet of impervious surface or fifty or more surface parking spaces. Stormwater controls are implemented to keep post- development flow rates from exceeding historic. This effectively protects downstream properties from increased runoff which generally occurs when the amount of the impervious surface increases. Existing drainage systems are to be designed to handle a 25 -year storm event; therefore stormwater control facilities shall be designed so the historic 25 -hear flow is not exceeded. The facility does not need to detain any runoff until the historic 25 -year runoff rate is exceeded. Stormwater control facilities shall be designed for the major and minor storm event. The major event will be the 100 -year storm and the minor event is the 25 -year storm. The facility shall have an emergency spillway or additional outlet for the 100 -year storm. The facility shall be sized to store volume created from the difference in historic and developed 25 -year storm event. The release rate from the facility shall not exceed the 25 -year historic flow rate. Design Methods One of the most widely used procedures for determining storage volume is the Storage- Indication Method. This flow routing method consists of a trial and error process based upon the Continuity Equation. The SCS National Engineering Handbook, Section 4, Chapter 17, provides an in -depth explanation of the subject of flood routing. A simple but less accurate method for estimating detention storage is the Graphical Storage Method. This method was developed by SCS and is explained in the SCS TR -55 Manual. This method is particularly suited for small detention basin designs, preliminary estimates of storage requirements, and for estimating the required size of temporary facilities. If using the Graphical Storage Method, failure of the structure must not endanger or result in a loss of life and a calculated storage volume error of +/ -25% must be tolerable. Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 63 Adopted November 6, 2001 Open Channel Flow Developers shall design and construct new or modify existing channels to adequately handle the required design storm. Manning's Equation (V= 1.49/nR2/3 S 1/2) and the Continuity Equation (Q =VA) should be used to calculate the velocity and flow capacity of an open channel. After the velocity and capacity of a channel has been calculated, it should be compared to the permissible velocity and maximum capacity of a channel. If the anticipated velocity and capacity is less than the permissible velocity and maximum capacity, then the channel is considered to be adequate. The maximum permissible velocity of a grass lined channel shall be 5 feet per second. Channel linings are required if either the capacity or velocity of a grass -lined channel is not adequate. Channel linings which stabilize a channel by preventing erosion and increasing capacity must be properly designed for the anticipated capacity and velocity. See Figure 3 -2. Channel linings are usually classified as either rigid (concrete, asphalt) or flexible (Rock rip rap). Rigid channels can handle greater capacities and permissible velocities. Flexible channel linings are less expensive, safer for roadside, self - healing, filter contaminants and permit infiltration, but have a lower flow capacity and may experience erosion damage. Culverts and Storm Sewers All culverts and storm sewers in the Town of Avon shall be sized to handle the 25 -year storm unless it is beneath or adjacent to an arterial or collector street. Culverts and storm sewers beneath or adjacent to an arterial or collector street must be designed for the 100 -year storm. Facilities shall be designed so there will be no major structural damage or loss of life from the 100 -year runoff event. Designers shall assume developed conditions for any adjacent undeveloped lots. For maintenance reasons, no culvert within the Town of Avon should be smaller than 18 inches in diameter (21" x 15" arch culverts are acceptable). To increase the hydraulic efficiency of a culvert (preventing scour at the inlet and undermining at the outlet) finished ends may be required. Finished ends (in the order of greatest hydraulic efficiency) include headwalls, flared end sections, mitered ends, and rip rap. Headwalls can be concrete or a combination of textured concrete and masonry so they not only increase hydraulic efficiency but are aesthetically pleasing. Designers should check the inlet and outlet control conditions. The maximum allowable headwater depth from the 100 -year storm shall be 1.5 times the culvert diameter, or 1.5 times the culvert rise dimension for shapes other than round. If approved by the Town of Avon, it may be satisfactory to allow excess water from the 100 -year storm to sheet flow across a roadway provided minimal erosion and property damage will result.

Town of Avon Residential, Commercial, and Industrial Design Review Guidelines Page 65 Adopted November 6, 2001 Minimum and maximum velocity must be considered when designing culverts. A minimum velocity of 3 fps is recommended for a pipe to be self - cleaning. The maximum velocity is dictated by the outlet channel conditions. An outlet velocity less than 5 fps is recommended for grassed lined channels with minimal erosion protection. Outlet velocity shall never exceed 12 fps. Culverts shall be designed to permit free unobstructed passage of debris and silt, or provide for their deflection and/or collection at a point upstream. If a battery of pipes is required, a clear space of one -half the pipe diameter (one foot minimum, four foot maximum) must be provided between pipes. Cleanout access shall be provided at least every 200 feet for pipes up to 24 inches in diameter and every 400 feet for pipes larger than 24 inches. Cleanouts are also required at all bends in all pipe sizes. Submittal Requirements A stormwater control plan is required for projects which have more than 25,000 square feet of impervious surface or fifty surface parking spaces. The stormwater control plan must be prepared by a professional engineer licensed in the State of Colorado. The Town of Avon may require a stormwater control plan for any site which it feels has special conditions that warrant investigation. The stormwater control plan shall consist of a plan sheet and report which evaluate the existing and proposed conditions. The required pollution control plan for the site may be combined with the stormwater control plan in a single report. The stormwater control plan shall contain the following: Plan Sheet The plan sheet shall include the following: 1. Topographic map (not less than 1 " =40') of the site which shows existing and proposed drainage patterns (i.e. grading plan). Basin vicinity map (i.e. USGS quad) which shows the limits of the tributary area(s). Location of proposed streets, driveways, buildings, homes, Parking areas and other structures. 2. Location, size, slope, and capacity of all drainage structures (i.e. culverts, storm sewers, drainage channels, inlets, etc.). 3. Expected peak discharge at critical locations (i.e. drainage structures, outfalls, etc.). 4. Sufficient details for construction. Narrative The narrative shall include the following: 1. A general description of the project. 2. A description of the existing and proposed land uses. 3. Calculation method with a listing and justification of all coefficients and assumptions used in the calculations. (All calculations shall be attached to the narrative as an Appendix). 4. A description of existing, proposed and tributary drainage patterns. 5. A summary of the historic and developed runoff rates and volumes. 6. Description of existing and proposed drainage structures (detention pond, culverts, etc.).
