THESE FINDINGS OF FACT AND RECORD OF DECISION ARE HEREBY APPROVED: BY:______________________________________ DATE: ___________________ Jim Clancy, PZC Chairperson   January 5, 2016 PZC Work Session                                    Wildridge Duplex Standards  PAGE 1 OF 3        To:  Chairman Jim Clancy and Planning and Zoning Commission  From:    Matt Pielsticker, AICP, Planning Director  Date:  December 23, 2015  Agenda Topic: Wildridge Standards     Introduction  At the November 17, 2015 meeting, the Avon Town Council continued Ordinance 15‐11, an Ordinance  drafted to create a new PUD amendment category for the Wildridge subdivision.   The Ordinance is  intended to address PUD Amendment applications specific to duplex properties proposing to develop  as two separate lots and two single‐family structures.   The Ordinance was continued by Council until  the January 26, 2016 meeting with direction to work with PZC on the eligibility and standards for this  type of application.  Additionally, direction was provided to take another look at incorporating more  stringent design standards to future development the WIldridge Subdivision, including “coast to  coast” duplexes.        The intent of the January 5, 2016 Work Session is to review Ordinance 15‐11, and determine if additional  amendments to Ordinance 15‐11 are in the interest of PZC based on the additional information  attached and included herein.    Background  Recent development within the Wildridge subdivision has prompted a number of discussions with  Town Council and the Planning & Zoning Commission questioning the adequacy of current  development regulations.  Of particular concern are PUD amendment applications that result in lot  splits and change the building type from a duplex (or more attached units) to single‐family‐detached  units.   Council and PZC indicated interest in adopting additional review criteria for review of lot split  PUD Amendments to improve mitigation of potential impacts to affected properties and to codify best  practices incorporated in past lot split PUD amendment approvals.     Among the changes shown in Ordinance 15‐11, a new category of review criteria specific to minor PUD  amendment applications that result in lot splits in Wildridge is prescribed to better address the specific  needs of that environment.  PUD amendment proposals would need to address specific site  characteristics unique to the Wildridge neighborhood to demonstrate that a development proposal is  not more impactful than development proposed under the existing site allowance. The language is  intended to provide the Planning & Zoning Commission with ample discretion to review proposals on a  site‐by‐site basis. New language and sections are shown in red.       Most notable of the proposed code text revision is a change in the review and final decision that is  now proposed to be completed by the Planning & Zoning Commission, rather than Town Council, for  applications to amend the Wildridge PUD.  However, applications that propose significant deviation  from the Wildridge PUD (i.e. zone change from residential to commercial) will continue to be a Town  Council consideration and approval process.        January 5, 2016 PZC Work Session                                    Wildridge Duplex Standards  PAGE 2 OF 3    Duplex Lot Splits  In 2010 during the drafting of Title 7, Development Code, Avon Municipal Code, Town Staff and the  Town Attorney worked toward a set of standards to address the same circumstance of a duplex lot  being split into two single‐family lots and structures.  Below in blue text is the 2010 code language  (never adopted), and is included only to see if the criteria/approach are worth considering in whole or  in part in addition to or supplementing portions of Draft Ordinance 15‐11.    Wildridge Duplex PUD Amendment Criteria. The purpose of this section is to establish criteria for the  review of duplex subdivisions which propose to break‐up the bulk and mass of potential duplexes on  duplex lots in the Wildridge Subdivision and by creating two (2) single‐family homes of a limited size  which result in two (2) smaller structures, rather than one (1) large monolithic structure and which are  sited with adequate separation between the two buildings.  A proposed subdivision of a duplex lot  which does not meet the criteria in this section must follow the “Major PUD Amendment” process.   1. Minimum Lot Size:  one (1) acre.    2. Maximum Unit Size:  The two proposed single‐family homes shall not be of a combined gross  floor area greater than 6,000 sq. ft. and shall be configured in a primary/secondary  arrangement with the primary structure comprising at least sixty‐percent (60%) of the total  floor area and the secondary structure comprising a maximum of forty‐percent (40%) of the  total floor area.  3. Building Envelopes:  Any request to build two (2) single family homes on a lot platted and  zoned for a duplex must be accompanied by a Duplex Subdivision Plat depicting two (2)  separate building envelopes which meet the following standards:  (i) are each no greater than 1,800 sq ft in area,   (ii) are at least twenty (20) feet apart,   (iii) conform to setbacks,   (iv) are sized, configured, and located in a manner consistent with surrounding  development,   (v) respond to natural contours to minimize site disturbance,  (vi) and avoid steep slopes which exceed thirty percent (30%) grade where  practical and in no case include steep slopes which exceed forty percent (40%)  grade.   4. Compatibility:  The newly proposed single‐family lots shall be compatible with the average size  of the ten (10) closest lots to the subject property; and, shall be configured and placed on the  lot in a manner which responds to the natural topography without causing excessive grading  and site disturbance.  5. Access & Easements:  A single access easement shall be located and depicted on the proposed  Duplex Subdivision Plat in accordance with §7.28.030, AMC.    Duplex Design Standards   Currently, no codified development standards exist to prevent a “coast‐to‐coast” duplex design. The  PZC will discuss this subject to identify concerns and determine the standards that may be proposed  for codification.  The intended outcome of this discussion is to provide staff with specific direction to  recommend amendments to the Development Code.  Again from 2010, draft code language (never  adopted) is shown below in blue for consideration.        January 5, 2016 PZC Work Session                                    Wildridge Duplex Standards  PAGE 3 OF 3    Duplexes/Tri‐plex/Quad‐plex: A continuous row of identical homes along a block is  prohibited.  Individual structures shall be differentiated through two or more of the following  methods:   Use of distinct color variation and materials between individual structures;   Variation in garage orientation;   Use of distinct variations in roof form; or   Use of distinct variations in architectural features, such as porches, roof form, windows, or  similar feature, between individual structures.    Wildridge Design Guidelines   At the November 17, 2015 Council meeting, some Council members discussed their desire to reconsider  the original guidelines for the subdivision.  Attached to this report are the original Design Guidelines  for the Wildridge Subdivision.  We will discuss these guidelines, and Staff will ask PZC to consider  which of these guidelines may warrant incorporation into Town Code.      Attachments   Ordinance 15‐11   Wildridge Design Guidelines   Wildridge Development Summary   Ordinance No. 2015-11 – Minor PUD Amendment to Wildridge PUD FIRST READING - November 17, 2015 Page 1 of 5 TOWN OF AVON, COLORADO ORDINANCE 2015-11 AN ORDINANCE AMENDING AVON MUNICIPAL CODE TABLE 7.16-1 AND SECTION 7.16.060(h)(1) CONCERNING AMENDMENTS TO WILDRIDGE PUD APPLICATIONS WHEREAS, the Avon Town Council initiated an application (“Application”) to amend the text of the Avon Development Code (“ADC”) in accordance with Section 7.16.040 of the ADC; WHEREAS, the Application would amend Sections 7.16.060(h)(1) PUD Amendment Categories and 7.16.060(h)(2) Reviewing Authority and Table 7.16-1, Development Review Procedures, in accordance with the Code Text Amendment; WHEREAS, the Avon Planning & Zoning Commission held a public hearing on September 29, 2015, after publishing and posting notice as required by law, considered all comments, testimony, evidence and staff reports provided by the Town staff, considered such information prior to formulating a recommendation; WHEREAS, after conducting the noticed Public Hearing, PZC made the required findings to recommend approval of the application to the Town Council; WHEREAS, the Town Council of the Town of Avon held a public hearing on November 17, 2015 after posting notice as required by law, considered all comments, testimony, evidence and staff reports provided by the Town staff prior to taking any action on the Application; WHEREAS, pursuant to AMC §7.16.040(c), Review Criteria, the Town Council has considered the applicable review criteria for a Code Text Amendment and found the Application in compliance with the review criteria, and specifically finds that the text amendment is necessary or desirable to respond to changed conditions, new planning concepts or other social or economic conditions and promotes the health, safety and general welfare of the Avon community; and, WHEREAS, approval of this Ordinance on first reading is intended only to confirm that the Town Council desires to comply with state law, the Avon home rule charter and the Avon Development Code by setting a public hearing in order to provide the public an opportunity to present testimony and evidence regarding the application and that approval of this Ordinance on first reading does not constitute a representation that the Town Council, or any member of the Town Council, supports, approves, rejects, or denies the proposed zoning or other matters in this Ordinances.

It is of prime importance to the continued aesthetic and ecological quality of t+?ildridge that all structures and landscaping are compatible with one another and in harmony with the natural surroundings. AREA CHARACTERISTICS Wldridge is located in the Town of Avon in the Iwrth Central Colorado Rocky Mountains approximately ten miles west of Vail, Colorado. TOPOGRAPHY Elevations within the project range from 7,740 feet to 8,930 feet above sea level. Topographically the site is dominated by sharply defined north -south trending ridges and valleys which result in a predominance of building sites with east, south or westerly orientations, Building sites range from gently sloping meadows and ridge lines to valley walls with slopes from 30 to 40 %. V E G E T A T I O N Sage, native grasses and forbes domimate the Wildridge site with only occasional small stands of oak brush, mountain mahogany or aspen. Areas disturbed by construction of roads and utilities are being re- vegetated with native grasses and forbes by the developer. W I N D Prevailing winds are westerly with gusts above 25 M.P.H. Gentle, warm, dry breezes dominate the summer months, stronger breezes occur in the spring and fall, and winter winds bring some blowing and drifting of snow. P R E C I P I T A T I O N Precipitation averages 18 inches a year, primarily in the form of snow falling from October to April. T E M P E R A T U R E Temperatures in winter vary widely: daytime temperatures can range from 15 degrees F. below zero to 50 degrees above; night temperatures can range from an extreme of 40 degrees below zero to 30 degrees above. S=er temperatures vary widely also, with possibility of frost occuring in every month; daytime temperatures may be in the nineties with night time temperatures in the sixties with occasional lows near freezing. Skies are sunny and clear throughout most of the year, GL' 0L0GY The site is underlain with sedimentary bedrock covered by a mantle of sandy to silty clay soils of moderate alkalinity. These soils range in depth from a few inches to an estimated 15 to 20 feet in some areas. The bedrock is l and thinly bedded such that the upper portions should be rippable with some areas of harder limestones and sandstones requiring light blasting to facilitate excavation. BUILDING SITES The siting of individual structures on the landscape can enhance or detract from the cohesiveness of the total development. These recommendations will address specific physiographic relationships which are to be found in Wi- ldridge: The basic relationships which have been determined to most influence structure siting are related to site slope, vegetative cover and the prominence of a building site as it is viewed from other areas within the developement. There are lots within the development which present unique opportunities for the individual builder because of access, orientation, view, etc. While these lots present the essence of '.4ildridge for the individual homeowner they also present the potential for the compromise of those same goals for o biers , R I D G E S Those lots which have been placed on "visible" ridges present the most sensitive siting considerations, particularly where natural vegetation is -minimal. Buildings placed on "risible" ridges where they break the skyline as viewed from other lots within the development break the natural landforms and therefore compromise dramatic vie<as . Buildings placed with roof lines below the brow of the ridge or below the height of a vegetative screen will preserve the continuity of the total site. 3 B U I L D I N G O N S L O P E S 4 Within concentrated areas of development the visual impact of an individual structure on neighboring homeowners is inevitable. While architectural guidelines have been established to promaote an aesthetic compatibility of all structures throughout the development each project should be reviewed with consideration as to potential attenuation of view. Building sites within Wildridge have varying degrees of slope, 71here are a number of design alternatives which may be anployed by the designer to accommodate site slope. The objective should be to fit the building or access drive to the existing landform, minimizing their visual inipacts. The structure should conform to the natural landform. Excessive cut and fill or stilts should be avoided. The structure should be stepped with the landform avoiding large areas of exposted foundation or the necessity for excessive cut and fill, SLOPES 0 % -20% Sites with slopes less than 207. present no significant building and vehicular access probldns. These sites should maintain 25' front yard setbacks or greater. STAPES 20 °; -30% S ites with slopes greater than 20% and less than 30% may require a 10 foot mini*.nmm front yard setback for the garage. This i•rill allow the garage to be as close to the road as possible thereby reducing the amoun of cut and fill necessary for driveway access. The garage may be attached or seperate from the residence, however the residence shall maintain a 25' front yard setback.

The landscape section ccnstains specific recommendations as to revegetation. Where structures are to be sited in wooded areas care should be taken to maintain vegetation on thenorthandwestsidesofthebuildingwhereitwillactasawindscreen. [ Were possible evergreens should be used for this purpose as they hold their foliage through the winter, Deciduous trees should be maintained or introduced on the south side of a structure in that theyallowthepenetrationofsuninthewinterandprovideshadeinthesummer. Where possible, building sites or road a1ugmients should not be located in the transition zone I tween a wooded area and an open area. The transition zone is an important feature of wildlifehabitatasT,a--11 as a unique feature -visually. T , - There the siting of a building or road in the transition zone is necessary, vegetation should be introduced to create a new transition zone.

Canprase of same characteristics will be required by some sites, however Wildridge generally has south facing slopes which relate to both solar orientation and distant views. T \ ut-h This diagram visually displays the major site orientations that should be considered when designing buildings in Tr7ildridge The best long views and the best solar orientation are to the south with south -east and south -west orientations also being good. North facing views are shorter and into the mountain. The optL= orientation for a structure will provide sunlight, winter -rind protection and view, On the Wildridge sites, the best overall orientation in most cases is toward the south -east. 10 B U I L D I N G MASSING Buildings located on non -treed lots will be highly visible and require more control of scale, massing, and materials. Structures, to the extent possible, should be tucked into the earth to present a low profile. Roof lines of buildings on open, non -treed sites should run with the slope of the land. Articulate building plans in response to sloping sites to reduce building scale and create spatial variety, 11 Articulate vertical massing rather than creating unbroken vertical masses to help reduce scale and create spatial variety. h- - k -a_,n ln,' - 574Z "__ ialND EFFECTS Winds are most prevelant in the spring and fall when their cooling effects are of little importance and are aggrevating to outdoor activities. Winter winds increase heat loss from structures especially when building openings are oriented toward the north. On open, non -treed sites, the effect of winds will be much more prevelant, Buildings should be designed to allow winds to slide over the structures rather than "stop" the wind, BUILDING MATERIALS & ELEMENTS A strong com=ity image and sense of place can best be created for Wildridge by encouraging the architecture of private residences to be understated; not competing with other residences or public use buildings. Public or com=ity buildings and natal land features should be the focal ooint of Aldridge. Building materials and colors should be those that blend with the indigenous character of the area. The use of artificial materials will be discouraged and the use of color should be consistent with the natural earth tones of the site. The following building design elements are established as guidelines to assure a continuity of building character, 12 I COLOR All color applied to exterior cod surfaces shall be semi - transparent stains that allow the grain of the cod to show through. The color of these stains shall be earth tones indigenous to the site and shall be one of the following colors. (Colors listed are for Olympic semi- transparent stains. Other matching semi- transparent stains are acceptable): Basic structure colors: 900, 901, 902, 904, 906, 908, 909, 911, 914, 916, 917 and 918. rim colors: (limited to 107. of the structure) any of the colors listed for the basic structure but deeper in value. ROOF FACIA All buildings shall have ,md roof facia boards of 12 inches or deeper. K . iii Roof materials shall be red cedar shakes or sod only, Sod roofs shall pitch as re for drainage but shall tie to earth grade on at least one side. 14 ROOF PITCHES 1 15 On open/non -tree covered sites roof pitches shall approximate slope of the natural contour. The ridge of the roof shall run perpendicular to the slope. Roof pitches on tree covered lots are not as visable and therefore do not have to approximate the slope of the ground.. A 3:12 roof slop_ e is the minima„ for shake roofs. The ridge of a roof shall not occur at a vertical wall. The roof surface shall counter pitch from the ridge a minimum distance of four feet, as illustrated. I& 0 -- SOLAR CONSIDERATIONS The use of passive solar design principles should be encouraged for all structures in Wildridge. Solar orientation in most cases is excellent and the climate allows a high return on cost invested when compared to many areas of the country. The winter sum is at an angle of 28 degrees on December 21st at noon. Proper window location and size will allow deep sum penetration into the house. The stunner sun is at an angle of 74 degrees on June 21st at noon and proper overhangs over south facing windows will restrict or eliminate sun penetration into the house. 16 I,hean designing the plan of a residence the following considerations for roan arrangement should be follou-ed. loci ; -br rao - 0 W corm c^r 1 Cl' a INIr 9 dI vi 9 4 rrcwf c -fie c",G r" } as "all cz. EC lcw-Lt¢A t cjcwt- - GI UQir dU11 ^ rr wir vr -{zc Building entrances should be designed to minimize heat loss. Entrance doors should be sealed tightly to prevent heat loss and heat gain. Air locks or vestibules can be used for unheated storage or as mid rooms. Air locks can prevent large air exchanges and reduce heat loss due to infiltration. Air locks are most effective when placed on the south or east sides of buildings. Wingwalls should be incorporated with air- locks on north and est sides of the building. The use of mass within a building is important for the storage of heat. By virtue of their mass, all materials have the ability to store heat. Certain materials such as stone can store large amounts of heat. 18 Massive materials can be used most effectively to moderate interior temperature if placed within the structure rather dim outside of the structure. V-781aM - - In winter the mass or heat sink absorbs heat SUY1 during the day when air temperature is greater than the mass temperature. U the room air temperature drops below the mass tarperature heat is radiated back into the roan. This principle may be applied to floor surfaces as well as walls. Wall and roof construction should be designed to m; = ze heat loss. 19 A plastic vapor barrier positioned on the "warm" side of the wall and ceiling will significantly decrease air penetration and heat loss. r a (ecr'za coc - ra^ i^q Some design considerations that will result in energy conservation: OA thermal resistance value of R30 should be a minim, an standard for insulation in roofs. A thermal resistance value of R19 should be a minimLm standard for the insulation in the floor above basements, garages, and crawl spaces. A thermal resistance value of R16 should be a minurnmi standard for insulation uz outside walls. Upper portions of walls are particularly important. GInsulating glass consisting of two or more panels with dead air space between each panel should be used, 20 QWindow area should be kept to a minimn on all sides except the south, Q Insulated window coverings, * ,bich can be closed at night and en the building is not in use, can greatly reduce energy loss. Q Window sashes with thermal breaks should be used to reduce heat loss. LANDSCAPE GUIDELINES L A N D S C A P E G U I D E L I N E S Plant material should be used to reduce the visual dominance of structures and man induced elements such as buildings, retaining walls, fences, road cuts, and automobiles, Landscape improvements which are reflective of the area's mountain characteristics should daninate the architecture of Wildridge, Trees introduced in hanesite landscaping are to be material predominately consistent T,7ith the character of the native mountain landscape. ( See plant list.) Plants used for accent or to achieve spatial design considerations may be adapted non- native material. (See plant list for approved accent plant material.) Vegetation may be introduced for the purpose of erosion control, visual screening, or scale reduction in the large landscape. OIrrigated lawn areas utilizing native and adapted non- native plants may be maintained on slopeslessthan25% (4:1), Where lawn areas are established they shall have an automatic irrigation System. 21 OIkidisturbed native stands of sage brush, grasses, and forbes may be maintained if they are in large areas. Small areas tend to look unkept or neglected, Q S tands of native gambles oak, aspen or spruce may be incorporated into an irrigated lawn to recall or support the visual image of the surroounding plant con z Small building sites where the majority of the existing native plants are disturbed should be totally re- vegetated as specified by the plant anaterial list. OBuildirg sites sloping in excess of 25, (4:1) shall be limited to a maximum of 3,000 square feet of irrigated area which shall be contiguous to structures on site, OPlanting outside of defined irrigated areas shall be limited to native species comparable to the immediately surrounding plant community (ample: aspen and spruce should not be introduced on sage brush and grass hill sides outside of the defined, irrigated area ) QIrrigated landscape areas should be defined from native vegetation areas by timber, stone wall, or edging elements, OPlant materials in irrigated areas can help subordinate structures to the landscape and lessen their visual impact. 22 GThe building pad, foundation excavation and cut and fill for driveways shall be designed to minimi disruption of existing trees and ground cover. C)On tree covered lots minima th of existing trees may be allowed to improve distant views and solar gain. S I T E I M P R O V E M E N T G ii I D E L I N E S QThe maxivarn grade for a cut or fill slope in severe circumstances shall be 1 1/2' horizontal to 1' vertical. Rze prefered max:LTm slope for areas of cut and fill where re- vegetation is necessary is 2' horizontal to 1' vertical. QThe maxinasn slope Length for severe cut or fill slopes shall be: 1 1/2:1 through 2:1 maxin n slope length = 20 feet 2:1 through 3:1 maxi -Tan slope length = 30 feet QBedrock which is exposed in a cut slope may exceed the maxi 1 1/2 : 1 cut slope. The cut surface of the bedrock should be "sculptured" to create an irregular profile which approximtes natural rock outcropings on the site. Planting pockets ma be created in the "sculptured" rock for grasses and forties. 23 cUr .lcrG' Slope rounding creates a more natural appearing slope configuration and promotes rapid re- vegetation at the fringe of disturbed areas. i r VM DA11 topsoil should be salvaged from disturbed areas and respread prior to re- vegetation, inhere possible E-- .fisting sagebrush and grasses should be incorporated with stripped and respread top soil. eVegetative remains of sagebrush, gambles, oak roots, and native grasses will serve as nursery stock for new plants. LI 24 RE T A IN IN G S T R U C T U R E S Retaining structures should be used where cut and fill slopes will exceed the maxi= limits and to reduce total site disturbance. Qihe visible height of retaining structures should be limited to 6 feet, QRetaining structures are to be constructed of squared timber, concrete, stone or a canbi- nation of both, In the heavily trod areas round log retaini.rg structures :nay be used Q when retaining walls are required in heights exceeding the maxi= of 6 feet, multiple structures should be stepped back to create planting terraces. Q Planting material should be used to reduce the visual impact of large retaining structures, 25 GRADING QHorizontal and vertical variation in the graded cut and fill slopes will create a more natural ridge and valley configuration, Such undulations should correspond to the adjacent natural slope variations. Cut and fill slopes should be contoured and moulded rather than sliced. Q Cut and fill slopes with grades in excess of 3:1 shall be protected by an approved erosion blanket over mulch. Flatter areas susceptible to concentrated runoff water should receive similar treatment. r -+i C C.U'f'.' I Q Cut and fill slopes from 3:1 to 5:1 shall be treated by hydro - mulching or with other approved mulch. For best results seed and fertilizer should be applied prior to application of hydro -mulch (hydro - seeding or seed drilling followed by hydro- mmrilc'ning) , 26 1 r zz O Q Slopes to be re- vegetated with dryland species should be scarified (tilled) leaving an irregular surface to promote maximum, moisture retention and to create micro enviornments more conducive to seed germination and plant growth: Scarification equipment marks should rur: parallel with the slope contours: Okffni- benches create improved plant growth conditions as well as provide topographic relief to the slope. Tree and shrub plantings in these areas help to retain soil moisture and slow runoff: Plant material appropriate to the surrounding plant community should be introduced into these areas. a--I 27 D R A I N A G E Q Concentrations of snocmelt and patios and roof should be avoided, 1 storm water runoff from impervious surfaces such as driveways, r Q!
