A MSP acts as a sign code for a project and allows the sign administrator to approve specific signs that are in compliance with the MSP without going before the Planning and Zoning Commission. The proposed MSP includes signage criteria for tenant signs, a freestanding monument sign, address signs, bus stop signs, and a corporate logo on the building. Tenant Signs: Tenant signs consist of sandblasted resin composite panels with raised graphics and a border. The colors and graphics of the tenant signs will not be restricted by the MSP; however, the size, materials, location and lighting of the signs cannot deviate from the MSP. There are two types of tenant signs: Fascia and Arcade. The fascia tenant sign will be oriented for vehicular traffic and is illuminated by an eight - foot downcast "Sign-Glo" light. The proposed sign will have a height of 1' 10" and a length of 8'6" for a total signage area of 15.5 square feet. The arcade tenant sign will be oriented for pedestrian traffic and illuminated by the lights installed over the door in the arcade. The proposed sign will have a height of 12""' and a length of 3'6" for a total signage area of 3.5 square feet. Freestanding Monument Sign: The freestanding monument sign consists of sandblasted resin composite panels with raised graphics and a border. The proposed sign will have a height of 3'4" and a length of 6' for a total signage area of 20 square feet. The sign will have a 2'8" high stone base that will match the stonework of the buildings on site. The total height of the sign will be 6'. Two micro floodlights will illuminate the sign. For colors of the monument sign refer to the colored rendering. The location of the sign as submitted violates the sign code due to encroachment into the road right-of-way. Address Signs: The address signs (3 in total) consist of sandblasted resin composite panels with raised graphics and a border. The proposed signs will have a height of 2'4" and a length of 2' for a total signage area of 4.6 square feet. The address signs will not be illuminated. For colors of the address signs refer to the colored rendering. There will be Town of Avon Community Development (970) 748-4030 Fax (970) 949-5749 Lot C, ACBC, Master Sign Program July 17, 2001 P&Z Meeting Page 2 of 3 two address signs located on both sides of the main entry arch and one on the northeast corner of the employee housing building. Bus Stop Sign: The bus stop signs consist of sandblasted resin composite panels with raised graphics and a border. There will be two signs; one that says "Bus Stop" and the other says "Mountain Vista". There will be a 16" diameter Sheraton logo above each sign. The proposed signs will have a height of P and a length of 6' for a total signage area of 6 square feet. The signs will not be illuminated. For colors of the address signs refer to the colored rendering. These signs will face West Beaver Creek Boulevard. Corporate Logo: The corporate logo sign will consist of interior lit pan channel letters and leaves with red lexon lenses. The raceway that supports the letter and the leaves of the logo will be painted to match the building fascia color. The location of this sign will be on the top floor facing West Beaver Creek Boulevard. The proposed sign will have a height of 5'6" and a length of 5'6" for a total signage area of 30.25 square feet. Design Review Considerations According to the Town of Avon's Sign Code, Section 15.28.070 Design Review Criteria, the Planning & Zoning Commission shall consider the following items in reviewing proposed designs: 1. The suitability of the improvement, including materials with which the sign is to be constructed and the site upon it is to be located. The proposed materials (pan channel for the corporate logo and sandblasted resin composite panels for the tenant, bus stop, address, and the monument signs) are encouraged by the sign code. The locations of the proposed sign are well sited with the exception of the monument sign that will need to be relocated to 10' from the property line. 2. The nature of adjacent and neighboring improvements. The immediate area consists of residential, retail, and office space. 3. The quality of the materials to be utilized in any proposed improvement. The pan channel and sandblasted resin composite panels are consistent with Town standards. 4. The visual impact of any proposed improvement, as viewed from any adjacent or neighboring property. The proposed tenant, monument, address and bus stop signs will not have any significant impact to adjacent properties. The corporate logo sign will be similar to the Lodge at Avon Center sign. 5. The objective that no improvement will be so similar or dissimilar to other signs in the vicinity that values, monetary or aesthetic, will be impaired. The proposed signs will not have any significant impact to other signs. 6. Whether the type, height, size, and/or quality of signs generally complies with the sign code, and are appropriate for the project. The proposed signs comply with the sign code and are appropriate for the locations. 7. Whether the sign is primarily oriented to vehicular or pedestrian traffic, and whether the sign is appropriate for the determined orientation Town of Avon Community Development (970) 748-4030 Fax (970) 949-5749 Lot C, ACBC, Master Sign Program July 17, 2001 P&Z Meeting Page 3 of 3 Staff Recommendation Staff recommends approval of the Lot C, Sheraton's Mountain Vista Master Sign Program with the following condition(s): 1.

The Town should continue to be perceived as a contemporary mountain town, complementary tothe natural . The Town should appear as a cohesive unit comprised of simple landscape and unbuilt environs 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 accentuate 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 idents a neighborhood's built environ as it relates to the Town. " o - - • - • �,-� . «u, tuge nuaa P-ast Looking South towards Beaver Creek. Planning and Zoning Commission Procedures, Design Review Guidelines Adopted December 31, 2001 Page 2 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, compatibilitshou y be achieved through the use and proper consideration of the guideline criteria contained herein. ld " - --o - �•� l Ljgieuenu, r1IInglvo. 1 Planning and Zoning Commission Procedures, Design Review Guidelines Adopted December 31, 2001 Page 3 Authority The authority to enact `Design Review Guidelines' is granted by Chapter 2.16 of The Avon Municipal Code, which specifically states: C.

Site Development Guidelines 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, and the retention of neighboring properties `view corridors'. Planning and Zoning Commission Procedures, Design Review Guidelines Page 10 Adopted December 31, 2001 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 an identified 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 shall be revegetated with species not identified as noxious non- native species by the Colorado State Weed Extension agent. A list of Eagle County noxious weeds is provided in Appendix 2. 5. 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. 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. 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. 9. Adequate maneuvering for vehicles on site must be provided. Parking and Loading 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 Planning and Zoning Commission Procedures, Design Review Guidelines Adopted December 31, 2001 Page 11 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. 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 marked on the site plan submittal, to the extent specified on the Minimum Submittal Requirements checklist. ?. Maximum slope of disturbed slopes shall not exceed 2 feet horizontal to 1 foot vertical (2:1) 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. 1. Building siting and foundation excavation shall avoid the disruption of existing natural features such as mature trees whenever possible. �. All grading is required to be shown within the proposed `site disturbance boundary' on submitted application plan sets. Planning and Zoning Commission Procedures, Design Review Guidelines Page 12 Adopted December 31, 2001 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. 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.). Retaining walls cannot exceed 6 feet high in residential areas unless specifically approved by the Planning and Zoning Commission, due to a hardship not caused by site design. 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. 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). Planning and Zoning Commission Procedures, Design Review Guidelines Page 13 Adopted December 31, 2001 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 single-family unit (ie. 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. 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. Planning and Zoning Commission Procedures, Design Review Guidelines Page 14 Adopted December 31, 2001 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. B. Building Design Guidelines General Design Character In addition to the stated Design Philosophy, and General Design Compatibility, a building must conform with 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 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 such as flues, chimneys, cupolas, etc. n MM Villalluilli iI�11 It ' A"16 Me -W~ FA!AL MOPPgVA14cT1vO 6R^QE 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. Planning and Zoning Commission Procedures, Design Review Guidelines Page 15 Adopted December 31, 2001 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 which 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 (ie. stucco, siding, wood). 3. Natural or earth tones are encouraged as the dominant color with brighter colors used for accent. 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. No single wall plane may exceed 70 % of the elevation of any exposure. Breaks in the wall plane must 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. 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. Minimum overhang length is 18 inches. 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. Asphalt andfiberglass composition shingles must be of high quality and minimum weight of 300 pounds per square. Untreated shakes are not permitted. Class A, B, and C roofing materials are permitted. Planning and Zoning Commission Procedures, Design Review Guidelines Page 16 Adopted December 31, 2001 A typical example of expressive architectural interest on a Pueblo Revival home in Wildridge. 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 provided for all parking, drive, and walkway areas and may be required as a condition of design approval. 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. Floodlights are not permitted. Light spillover to adjacent properties must be minimized. 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. Duplex Developments Duplex developments must be designed in a manner which 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 which creates a unified structure with enough variety and architectural interest to distinguish a duplex from a single family home. Commercial and Industrial Projects Commercial projects shall reference the 1996 Town of Avon Commercial Design Guidelines for specific recommendations on architectural design. Though these guidelines are intended primarily for residential development, the following guidelines shall also apply to commercial projects in the Town. The use of pedestrian circulation through the inclusion of Malls, Atriums, and covered walkways is encouraged. Planning and Zoning Commission Procedures, Design Review Guidelines Page 17 Adopted December 31, 2001 Building design should provide for the convenient delivery of goods and services. Deliveries shall not interfere with pedestrian or vehicular access to residential areas of mixed use projects, and should be minimized to specific locations on an access plan. All commercial projects shall comply with all applicable recommendations of the Commercial Design Guidelines as attached in Appendix 8. C. Landscaain 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 ditches or back of curb, as applicable. Fire Resistant landscaping in areas with wildfires are 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. Planning and Zoning Commission Procedures, Design Review Guidelines Page 18 Adopted December 31, 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 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 of fencing is not acceptable. Limited use of split rail fencing to accentuate a landscaping transition may be acceptable. Planning and Zoning Commission Procedures, Design Review Guidelines Page 19 Adopted December 31, 2001 Erosion Control Erosion control is essential at all building sites.

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: Planning and Zoning Commission Procedures, Design Review Guidelines Page 42 Adopted December 31, 2001 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. 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 Planning and Zoning Commission Procedures, Design Review Guidelines Page 45 Adopted December 31, 2001 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. 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/nR2/3S1/2) 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.

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. 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). 2. Location of proposed streets, driveways, buildings, homes, Parking areas and other structures. 3. Location, size, slope, and capacity of all drainage structures (i.e. culverts, storm sewers, drainage channels, inlets, etc.). Planning and Zoning Commission Procedures, Design Review Guidelines Page 48 Adopted December 31, 2001 4. Expected peak discharge at critical locations (i.e. drainage structures, outfalls, etc.). 5. 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.).

Area Wide Guidelines 1. Siting Conditions 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 siting of buildings. Pedestrian accessways should be aligned and focused on features. Buildings and improvements should be designed and sited to conform to the natural terrain and to take advantage of views. Terraced buildings and parking will minimize site disturbance, provide less costly construc- tion and provide opportunities for privacy and views by grade separation. Passive solar design as a component of the architectural design of individual buildings is encouraged. The use of sun exposure -reducing elements such as overhangs, pergola's, canopies, eaves and awnings should be designed as integral components of the archi- tectural design. Outdoor spaces such as courtyards and plazas should have southern exposure to extend the periods of seasonal use and comfort. 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 spaces should be carefully consid- ered because of winter conditions. 2. Surface Parking Surface Parking is discouraged in the pedestrian oriented Town Center except for short-term and service func- tions. The predominant parking functions will occur in structures in the Town Center area. The more vehicular oriented Commercial Core is designated for surface parking. Views rer�dced huil�itt�t Solar FxposQ re Planning and Zoning Commission Procedures, Design Review Guidelines Page 53 Adopted December 31, 2001 All parking must be off-street, and ninety degree stalls are encouraged. Complete vehicular circulation includ- ing back-up and turn -around areas must be provided. 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. Driveway or maneuvering areas within a parking lot must be designed to provide for safe and reasonable maneuverability of vehicles. Perimeter Curbs: Each parking area should be provided and maintained with a concrete curb, not less than six inches (6") in height, securely installed and maintained. Striping: All parking spaces must be striped in a manner clearly showing the layout of the intended stall. Maintenance: All parking areas must be maintained in a safe and sanitary condition free of dust, mud or trash, and kept in good repair. Any alteration, enlargement or reduction must be approved by the Design Review Board. Provi- sions should be made for the removal and stockpiling of snow from all parking areas. Parking Area Landscape: All efforts should be made to screen parking areas with either earth berms or landscape or both. Earth berms shall be planted with shrubs or grasses. Parking area interior landscape is confined to islands. At the ends of all bays of six or more cars, a minimum 10' wide island is required. Trees are required. Flow- ers, grasses and shrubs are recommended additions. 3. Grading and Drainage The digging or removal of dirt from any parcel is prohibited except as necessary in conjunction with the landscaping of, or construction on, such parcel. No native trees shall be cut without the prior written approv- ooJ r'r11117 ��rfh BcrrnS a 4ffA��.:.I OF- gob fA EZX Larth Berms i Landscapc Parking Lot SCreeniny Land--;,-- a pcc/ island f arkini Arca 1nicrior Landscaping Planning and Zoning Commission Procedures, Design Review Guidelines Page 54 Adopted December 31, 2001 al of the Design Review Board. The builder is responsible for preventing erosion of the site both during construction and after the project is complete. Runoff of silt, debris or sedimentation onto adjacent streets, gutters, sidewalks, rights-of-way, storm drain systems or adjacent properties must be avoided. Drainage into common open space areas is not allowed except in existing natural drainage channels or drainage easements. Drainage swales should not surface drain across major walkways or trail systerm. Drainage shall be piped or rock lined if flows are significant and/or if it flows into natural channels. 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. Concrete gutters must be installed to receive drainage from asphalt and concrete. Paved areas must be designed to carry surface water to the nearest practical street, storm drain or natural water course approved by the Design Review Board. Concen- trated flows of water from parking areas must not flow by gravity over any other property, but should be collected in an appropriate manner within the property confines. A detailed drainage study, if deemed appropriate, must be prepared by a Civil Engineer and submitted to the Design Review Board for approval. See Appendix B (p. B-1) for technical grading and drainage recommendations. 4. Planting All landscape development, including specific landscape elements such as planters, retaining walls, and berms must be approved by the Design Review Board. Planning and Zoning Commission Procedures, Design Review Guidelines Page 55 Adopted December 31, 2001 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. Plants are to be installed and maintained according to sound horticultural practices. Plantings must be consis- tent in quality and character with the materials list. See Appendix B (p. B-1) Shrub planting beds should be mulched to prevent erosion and help retain moisture. All planting beds should be contained on all sides by a hard edge (i.e., sidewalk, wood or steel edging, building or curb). Snow loading should be considered when locating shrub areas so as to avoid winter damage to plants. Hedges, in winter, become snow fences and must be placed accordingly. Trees: • Trees must be planted at least four feet back from sidewalks or curbs to provide for tree growth with- out disruption of paving or pedestrian circulation. • Each tree must be no smaller than two inches in caliper. Replacement, if necessary, and maintenance of each tree is the responsibility of the builder. Dead trees must be replaced promptly with a tree of the same type, quality and size. • Trees should be massed or grouped wherever possi- ble to provide a greater immediate visual impact. • Tree plantings may not interfere with utility ease- ments. • Trees should be chosen and located to provide 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. • Care should be taken when selecting and locating trees so that Evergreen trees don't shade walks and streets in winter creating hazardous icing conditions; nor should they block south facing windows limiting solar access. Planning and Zoning Commission Procedures, Design Review Guidelines Page 56 Adopted December 31, 2001 The builder is responsible for providing all landscape development within the R.O.W. of streets or roadways along the parcel frontage. All portions of a site, disturbed by construction must be planted. .. Mulches: Mulches should be utilized to treat the areas around tree and shrub plantings in all zones. Grasses: Grasses should be used in one of two situations: • In large open areas aS a soil stabilizing agent and for visual effect (primarily viewed from vehicular traffic). • Close to pedestrian areas where visual relief from extensive pavement is desired. In large open areas numerous grass mixes can be considered. Thought should be given to water require- ments 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 wildflowers/bulbs require less water, less mowing and lend themselves well to the perimeter areas of the Town Center blending into the existing vegetation. In more intensively developed areas with pedestrian traffic anticipated, bluegrass mixes should be utilized to provide a lush, green appearance. Bluegrass mixes require more water and mowing than rough or dryland grasses and should be used judiciously. See Appendix B (p. B-1) for technical landscaping recommendations. 5. Irrigation Irrigation is required in all landscaped areas. The intent is to keep the plant material healthy in appearance by meeting plant water requirements for proper growth and development. The type of irrigation will be determined by the intensity of landscape development and the Planning and Zoning Commission Procedures, Design Review Guidelines Page 57 Adopted December 31, 2001 associated water requirements of the plant species. For example, parking lot islands that contain only river rock mulch and trees may receive a drip irrigation system, whereas plazas that have bluegrass, as well as trees and shrubs will require more traditional irrigation systems. Suggested irrigation techniques depending on the intensi- ty of landscape development include the following: • Automatic spray irrigation system • Manual spray irrigation system • Automatic trickle irrigation system • Quick coupler system 6. Exterior Furnishings Within the landscape, three-dimensional objects are the most readily perceived. Careful design and use of these elements in the public and semi-public areas is critical in order to convey permanence and identity, as well as theme. Furnishings should establish character through a unified design vocabulary, and provide strong visual continuity while fulfilling functional requirements. The articulation and design of site furnishings should be unique: a consistency of color, material, form and detail. Kit -of -Parts: A "Kit -of -Parts" concept is utilized for all public areas in Avon to provide a set of furnishings (bench, trash receptacle, light standard, etc.) derived from a common vocabulary of materials, forms and textures that can be put together in response to specific design situations (plaza, seating areas, etc.). The advantage of this approach is a visual continuity of form and materials to create a specific image. The elemenis-in•the Avon Kit -of -Parts are, for the most part, off-the-shelf catalog items. Private developers are encouraged to either use these designated elements or choose, with Design Review Board approval, similar related elements. A cohesive, relatively uniform visual image for both public and private areas will result from this approach. Tr -7'./7 C:CY-4 Ptar Ile eoltard Light Plantar Pelf Ki -f -of -Parte, Planning and Zoning Commission Procedures, Design Review Guidelines Page 58 Adopted December 31, 2001 7 Site furnishings including benches, trash receptacles, flagpoles, bike racks, sculpture and fountains are recom- mended. Key locations such as building entries, plazas, areas of positive views, and along walkways are encour- aged. If the developer chooses not to install a minimum of 2% of the site improvement budget for site furnishings, a cash in lieu settlement equal to 2% of the site improve- ment budget will be designated and surrendered to a public improvement fund for those elements. See Appendix A for streetscape element cut sheets. Signs Well-designed and constructed signs attract attention, create a sense of quality and contribute to the overall urban character. In general, all signs must conform to the Town of Avon sign code_ In addition, all building mounted signs should be located on a fascia or architec- tural detail designed for such purposes. Free standing identification signs should reflect the architectural character of the building. Flush mounted signs are encouraged with projecting signs allowed adjacent to the Pedestrian Mall. Within the Town Center and Commercial Core, the directional signs, street name signs and traffic safety signs should be similar in character as those designed for the public rights-of-way. The design intent is to provide elements with the same visual character throughout. See Appendix B (p. B-2) for technical sign recommenda- tions. 8. Screening and Fencing Service Area Screening: All service areas are to be screened from adjacent land uses by architectural features such as solid four foot (4') or six foot (6') fences and/or heavily massed plant materials. Buffering may be required by architectural features if excessive noise levels are anticipated or encountered. (tench s1&4+ p w�� Y�,�V.Y_• O P TDA Y'" y •!

Mechanical Screening: Ground -mounted equipment such as power transformers and air handling equipment must be screened from public view by either materials integral with the build- ing, a fence or landscaping, all of which must be approved by the Design Review Board prior to construc- tion. Utility boxes should be located away from buildings, toward parcel property lines. In all cases, plant material must be used to screen these boxes. Fencing may be used in combination with plant materials. Phone pedes- tals, meters and transformers will, whenever possible, occur to the side and rear of buildings. Vacuum breakers (irrigation equipment) will be located below grade in inspection pit housings or adequately screened by landscaping. Antennae must be installed within the principal structure. Trash Dumpsrers: Trash dumpsters shall be screened by a six-foot fence or wall similar in character to the adjacent structure, with access gates. Sight Lines: In reference to sight lines on corner lots, no object may be placed or planted on corner parcels which obstructs sight lines at elevations between two feet (2') and six feet (G') above the top of the street curb within a trian- gular area formed by the junction of the street and curb lines and a line connecting them at a point fifty-five feet (55') fromthd junction of the extended street curb lines or extensions thereof. No wall, fence or planter in excess of two feet (2') in height should be constructed or maintained nearer to the front lot line than the front building setback line. <iGA)i 7riarnyle Planning and Zoning Commission Procedures, Design Review Guidelines Page 60 Adopted December 31, 2001 Fencing: All fences, whether decorative or for screening, must be constructed of wood. Fences should be one of three types: Two rail open fence: Used when a barrier is desired without blocking views. Four foot (4') solid fence: Used when a barrier is desired with some blocking of views, such as utility boxes or cars. Six foot (6') solid fence: Used when maximum screening is desired. Security fences should be of the six foot (6') solid type. Chain link fences are discouraged except in unique situations. Masonry walls will be considered if they are designed as an integral component of the building's architecture_ No front, side or rear fence, wall or hedge may be more than six feet (6') high. 9. Lighting The lighting systems will serve functional and aesthetic roles. These include: • 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. • To reinforce the identity and character through form, color and materials of fixtures, visual light quality and placement. In all commercial/retail and office parcels, lighting must be designed and arranged so as not to reflect excessive direct or indirect light upon abutting or adjacent proper- ties. Pedestrian Scale Lighting: The use of low level light sources at the pedestrian scale to accent or illuminate the ground plane provides a _.T{NO R;ari Open Oill�IIIII!!!lfllll�fillflll(t1l< <��I�iI�I� IIIIIIIIIl�; lllllllllllll IJ IRIIINNIIIII renc in g Planning and Zoning Commission Procedures, Design Review Guidelines Page 61 Adopted December 31, 2001 special opportunity to reinforce the unique identity and "sense of place" found in the area. This is achieved by a variety of lighting fixture types and lower mounting heights. At night, these design elements provide light for safety and aesthetic effect. By day, the physical shapes and sizes lend animation and scale to pedestrian spaces. Fixtures at a maximum height of 16' will be utilized to illuminate pedestrian traffic areas. Additional pedestrian scale lights may be utilized, including smaller bollard lights (42" height) and canister type lights on overhead structures. Lighting for pedestrian areas should be incorporated into the building wherever possible. If this cannot be achieved, free standing pole lights may be utilized. See Appendix B (p. B-4) for technical lighting recom- mendations. 10. Handicapped Considerations Consideration for the handicapped should be a part of the design process for any project. Every structure should be accessible by the handicapped through the use of ramps and any necessary banisters or rails. Ramps must be at a maximum of eight percent (8%) grade. A minimum of two (2) handicapped parking spaces per 100 total stalls should be provided. These spaces should be clearly marked and as close to the building entrance as possible. Space width shall be a minimum of 12' with clear access to pedestrian walkways. All outdoor pedestrian areas should be accessible by the handicapped. Pedestrian 5taleLie fini. Planning and Zoning Commission Procedures, Design Review Guidelines Page 62 Adopted December 31, 2001 ARCHITECTURE A. Introduction The purpose of these Architectural Guidelines is to assist property owners and developers in the planning, design and construction of projects in the Town of Avon. These guide- lines attempt to set standards which will promote a harmoni- ous and successful, integrated development of the town. They are not meant to be limiting or restrictive, but seek to guide new development in a direction which will improve the town as it grows over the next 25 years. Unlike many architectural design guidelines, these do not promote any specific architectural style, nor do they attempt to reduce architecture to a set of rules and regulations, materials and colors. Basic principles of regional and contextual sensitivity are considered far more important in their contribution to quality of design than stylistic con- sistency. These guidelines encourage development which is designed with Avon's climate and urban context in mind, with sensitivity to site, adjacent development, sensible use of materials, thoughtful detailing, and a sense of appropriate- ness for its location in the mountains of Colorado. "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. 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. " B. Ares Wide Guidelines 1. Building Height Building heights within the Town of Avon are described in the Zoning Ordinance. Maximum height in the Town Planning and Zoning Commission Procedures, Design Review Guidelines Page 63 Adopted December 31, 2001 Center is 80' and in the Commercial Core 48'. Refer to the town of Avon Zoning Ordinance for detailed infor- mation on building heights. Special consideration should be given to chimneys, tow- ers, or other elements which may violate the height restriction, as they have the potential to add architectural character and variety to the skyline. Solar access is of primary importance within the town core, and all designs will 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 V = 40'- 0" showing shadows at noon on March 21, June 21, September 21, and December 21.) 2. 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 me- chanical equipment, or for architectural effect. Sloped roofs should have overhangs. Secondary shed -type roofs should have pitches no less than 4:12. Valleys and com- plex roof forms are a potential source of ice buildup and water damage, and should be used carefully and spar- ingly. The use of dormers (shed, peaked, eyebrow, etc.) is en- couraged to help break up large expanses of roof, to en- hance the useability of attic spaces, and to add archi- tectural interest to the roofscape. Roof materials must be carefully specified to withstand mountain climatic conditions. Necessary attributes for long-lasting roofs are: high strength, low absorption or permeability, and resistance to freeze -thaw damage. Roof materials within the Town Core may be the follow- ing: unglazed concrete tile, wood shingles, copper, standing seam metal, or terne-coated steel. Shake shin- gles, asphalt, and fiberglass roofs are prohibited. �'XCC7GY 1 chrMnsy o �we- 8vildinj geiJA4 n �t— ,e�f Prf�i�s Planning and Zoning Commission Procedures, Design Review Guidelines Page 64 Adopted December 31, 2001 Tile: Concrete tile is an effective roof in mountain climates. Tile should be used in a dull finish in colors compatible with the town (green, reddish brown, gray, for exam- ple.). Due to difficulties in detailing and constructing valleys and ridges, especially in cold roof construction, roof forms should be kept simple. Metal Roofs: Terne coated stainless steel or other high quality metal roofs with dull finish can be considered. Colors should be muted to fit within the context. Green, gray, reddish brown, or slate are appropriate colors. Wood Shingles: Cut shingles are preferred to shake shingles in mountain environments. Patterns of alternating exposure widths of shingles can add interest and texture to roofs. New materials will be subject to approval by the Design Review Board. Exposed metal flashing, gutters, downspouts or other building appurtenances must be copper, steel, iron, or aluminum, applied and fastened in a high-quality man- ner. When painted, these elements must be finished with a baked enamel paint, epoxy paint, or a silicon -modified alloy. Snow shedding is a major concern which must be carefully considered in the design of roofs in the Avon Town Core. 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. 3. Exterior Walls The form of exterior walls in the Town Core should Dor rn¢rs '-hed 04prmcr ��GLGgYDW �� Planning and Zoning Commission Procedures, Design Review Guidelines Page 65 Adopted December 31, 2001 grow out of a balanced response between the public spaces they enfront and the interior functions they en- close. Walls can be broken down in scale through the use of windows, doorways, recesses and setbacks. They can be further articulated through the use of different materials, patterns, ornament, texture and color. In addition to addressing the more formal design issues, wails must also respond to solar exposure: more open and glazed on the south exposure, more protected and solid on the north. 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. Building Massing is the primary way of achieving a sense of enclosure and works most effectively when zoning allows structures to be built to the setback line. Walls of commercial and retail spaces should be pre- dominately glazed, giving an open and welcoming quali- ty. Residential spaces should be glazed in a manner consistent with the level of privacy required with consid- eration to distance from the street and adjacent buildings. Office space should have a "legible" character as well, somewhere between retail and residential. The following materials are encouraged in the Town Core: Stucco and synthetic stucco: These materials are resistant to water and snow and can be used effectively at the "base" of a building where it meets the ground. They are also suitable on upper walls of buildings. Joints, variety of color, and changes in plan all help to create a sense of scale on stucco walls. .. ... Stone: Although costly, stone is an enduring material well- suited to the extremes of Colorado weather. It can be used at the base of buildings, up the wails, or in ele- ments 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 Build inoj enc-loscs pasi+roc ouidoow space Planning and Zoning Commission Procedures, Design Review Guidelines Page 66 Adopted December 31, 2001 with larger stones at the bottom gradually diminishing to smaller stones at the top. Woad Siding: This is an economical material for wall surfaces, but should be avoided when likely to be in continuous, contact with snow such as at the base of buildings. The scale of the wood siding (4", 6", 8" or larger) should be chosen to complement the desired design effect. Wood Shingles: This material can be used in lieu of wood siding and has the capacity to conform to a variety of shapes such as curves, bows, battered walls, etc. Heavy Trmber. Exterior elements such as porches, roof overhangs, dor- mers, and gables can offer the opportunity to use heavy timber elements to create interest, give scale, and signify areas of architectural importance. Concrete: Poured -in-place or pre -cast concrete can be used effec- tively if their use is judicious. Pre -cast column and spandrel covers, at grade or poured -in-place walls with large stone aggregate are examples of acceptable use of concrete. Details: Terra Cotta or ceramic the inserts are encouraged to add highlights or detail to walls. Care must be taken in the detailing and construction of inserts to ensure that they do not work loose from freeze/thaw cycles. The effect of clever detail touches can be significant. 4. Chimneys and Flues If properly designed, chimneys and flues can be impor- tant elements in the overall design of buildings which affect the roofscape and skyline. All flues should be en- closed in a finished material such as stone, wood, or stucco. The form of chimneys and flues should be consistent with the design of the building. Use of dis- tinctive chimney caps is encouraged. Where possible, 4bM' nays any building vents, flues, or other roof penetrations 4.:101 eale.' Planning and Zoning Commission Procedures, Design Review Guidelines Page 67 Adopted December 31, 2001 should be clustered and screened within chimney -like enclosures. Chimneys must be carefully located to avoid fumigation of adjacent buildings and ground areas. Generally they should be as high as possible and on the upwind side of the roof for best results. Particular attention must be paid to the location of ex- haust vents from commercial kitchens which can emit unpleasant odors and noise. These vents must meet or exceed local codes and are subject to modification and/or relocation at the request of the Town of Avon if the system does not perform adequately. 5. Windows Windows must serve many purposes in the design of buildings. They establish patterns, rhythms, and scale on the exterior walls, they respond to uses and needs on the interior, and they can be recognizable indications of what goes on behind them. They provide passive solar heating for interior spaces and also contribute to heat loss from within. Variety in the use of windows is en- couraged within certain limits. Commercial spaces must have large areas of glass opening onto public pathways, streets, or sidewalks (suggested goal is 75% glass). Residences, hotels, and other private uses should have more limited use of glass. In both cases, large uninter- rupted areas of glass are discouraged. Division of win- dows by mullions and muntins adds character and gives scale to the building. Aluminum, steel, painted wood, or clad wood windows are allowable. Prohibitions include: mirrored glass, snap -in muntins, glass curtain walls, and other assem- blies which are clearly out of character with the Town Core. b. Doors and Entryways Public Doors and entry ways 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 Planning and Zoning Commission Procedures, Design Review Guidelines Page 68 Adopted December 31, 2001 variety along the public right-of-way. Where possible, gates, courtyards, staircases, and bridges should be used to connect buildings and create outdoor rooms and linkages. Service doors out of view of the public 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 facade it should be covered with a porch or porte cochere. 7. Decks and Balconies 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 motel are discouraged. 8. Exterior Walkways Care must be taken in the design and location of exterior sidewalks 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. C. Town Center Guidelines "The Town Center is the urban core of the Town. It is envisioned to be an intensely developed area that is centered around an internal pedestrian circulation system. Emphasis should be placed on creating inviting storefronts and plaza areas for public interaction. Buildings should be closely spaced and range between four an eight stories. " 1. Building Form and Massing In general, building forms should be used to create definable public spaces between buildings. Buildings en - fronting the mall should create an edge to help define the mall space. Buildings on the south side of the mall Thts N& -7%16 L.1e cks e jcon� �s Planning and Zoning Commission Procedures, Design Review Guidelines Page 69 Adopted December 31, 2001 should step back above the second story to allow greater sun exposure for the mall. Buildings on the north side of the mall should step back above the second or third floor. The intention of these guidelines is to encourage the cre- ation of an intensely developed village without sacri- ficing views and access to sun in all public spaces. Buildings must be designed as elements of a townscape rather than as stand-alone buildings. They should be closely spaced and vary in mass, height, and bulk, while at the same time reinforcing a sense of positive outdoor space. Buildings off the mall should respond to site concerns of view, solar access, entry, service, public/private, and existing context, and will be given more latitude in form and massing than buildings on the mall. 2. Windows In the Town Center Area, windows must conform to the following criteria: Pedestrian Level: In Commercial spaces the mini- mum allowable glass areas is 75% of walls opening on to the Pedestrian or ground level. The maximum size of individual panes of glass is not to exceed 16 square feet. In general, areas of glass unbroken by wall or structure should not exceed 150 square feet. Pedestrian Level: Hotel or Office spaces at pedes- trian level should be as open as possible and not less than 50 percent glass, unless it is a north exposure, in which case glass may be reduced to 40 percent. The same restrictions apply to sizes of individual panes and areas of glass unbroken by wall or struc- ture. Upper Levels: Hotel, residential or offices have no requiremerlts'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. sun 15xpasure y /6 SF MaX rn S111 f a el OfW'nwj 1h P a// WrnclowS Planning and Zoning Commission Procedures, Design Review Guidelines Adopted December 31, 2001 Page 70 3. Doorways Doorways in the Town Center will serve a variety of needs from entrances to shops, and restaurants to hotels, offices, and residences. Opportunities for individual expression, craftsmanship, and statement of architectural , character are encouraged in the doors and entryways of the Town. Combined with shop windows, awnings, street furniture, and lighting, these entries will become important character -defining elements at pedestrian level. 4. Commercial Frontages The primary objective of Commercial Frontages is to Lbarways provide visual identity for the activity within the com- mercial space to promote the uses within. These front- ages also contribute to a visually dynamic and cohesive street level. Individual tenant frontages must assert their individual identities, while at the same time fitting within there specific architectural context. The following guidelines should be consistent in the design of these storefronts: • Variety of individual elements such as window openings, trim, storefront configuration, etc. must be achieved within. The proportions and scale of the associated building materials may vary in detailing and color while remaining compatible with the overall building design. • Window displays should be illuminated with incan- descent or color -corrected metal halide fixtures. (Fluorescents are prohibited in display windows.) This illumination, to be left on at night, will con- tribute to lighting the adjacent pedestrian path or walkway. • Doors and windows, when opened, must not project into the public right-of-way. • Canvas awnings are encouraged to add color and form to storefronts. Awnings should be intermittent rather than uninterrupted and linear. D. Commercial Core District Guidelines "This district is characterized by existing one to three story commercial development that is oriented primarily to shop - Planning and Zoning Commission Procedures, Design Review Guidelines Page 71 Adopted December 31, 2001 pers who arrive by automobile. The district serves as a regional service center for daily and long-term needs of permanent and seasonal residents of the surrounding residen- tial neighborhoods. " "Strengthen the rale of the Town Center Mall as a unifying element for the core area." In general, guidelines for the Commercial Core District are similar to those in the Town Center. This section expands on the Area Wide Guidelines and tailors them to fit the needs of the Commercial Core area. 1. Building Form and Massing Building heights within the Commercial Core District are described in the Zoning Ordinance. Building heights are limited to a maximum average of 48 feet. In an effort to encourage long-term rental and other forms of resident housing, the Commercial Core District zoning allows an accessory use of housing in the ratio of two square feet of housing for every one square foot of retaillcommercial use. This type of accessory use has the potential to transform a one-story retail center into a 3 -story mixed-use complex. The massing of these mixed-use structures should in general reflect the public retail use at ground level and the private residential use above. Residential entries should be separate and distinct from retail entries, and access to nearby desig- nated parking is an important factor in determining the location of residential entries. 2. Windows In the Commercial Core area, windows must conform to the following criteria: Pedestrian'L'evel: In Commercial spaces the mini- mum allowable glass areas is 75 % of walls opening on to the Pedestrian or ground level. The maximum size of individual panes of glass is not to exceed 16 square feet. In general, areas of glass unbroken by wall or structure should not exceed 150 square feet.

Doorways Doorways in the Commercial Core will serve a variety of needs from entrances to shops, and restaurants to hotels, offices, and residences. Opportunities for indi- vidual expression, craftsmanship, and statement of archi- tectural character are encouraged in the doors and entryways of the Town. In general, entries should be under an arcade or a covered porch. 4. Commercial/Retail Frontages The primary objective of Commercial Frontages is to provide visual identity for the activity within the com- mercial space to promote the uses within. These front- ages also contribute to a visually dynamic and cohesive street level. Individual tenant frontages must assert their individual identities, while at the same time fitting within there specific architectural context. The following guidelines should be consistent in the design of these storefronts: Variety of individual elements such as window openings, trim, storefront configuration, etc. is encouraged.
