For approximately the last year, staff has been examining particular sections of the code that dictate mass and scale of residential structures. Simplification of the code has also been a goal of this code analysis. This memo includes a synopsis of the interim review process, recommended text amendments, alternatives, and a Resolution recommending to Council adoption of the proposed code changes. PROCESS: Since July 1994, residential development has been reviewed by an interim process established by Ordinance 35. Ordinance 35 was to expire in February 1995, but was extended to May 30, 1995. Ordinance 35 provided this interim review process in order for staff to pursue substantial changes to the Land Use Code that will affect the character of residential development. In anticipation of the code changes, staff and the City Attorneys office have developed a policy for "pipeline cases." Section 24-7-1105 A. states that whenever the City Council or the Commission has properly initiated a development application to amend the text of this chapter or the official zone district map, and the Commission has, by resolution, recommended to the City Council approval of such amendment, no building permit shall be issued by the chief building official which would be prohibited by the proposed amendment for a period of six months following the date of the Commission's recommendation. However, Section 24-7-1105 B. states that the Council has six months to either refuse to consider the amendments or adopt the amendment. If council does not adopt or by resolution does not consider the Commission's recommendation, any building permit which conforms with the existing code may be issued. Therefore, if the Commission, by Resolution, recommends code changes to Council, any building permits that are inconsistent with the Resolution will be suspended from issuance beginning May 9, 1995. However, if a completed development application is submitted prior to 5:00 p.m. on May 9, 1995, the applicant will be permitted to proceed with the approval process based on the current code. This includes proposals requiring review by the Interim Overlay Committee. Council will review the Commission's recommendations at first reading May 22 and second reading June 12. BACKGROUND: I. In May of 1994, the Historic Preservation Committee unanimously voted to request Council to adopt the "Neighborhood Character Guidelines" for development review. The HPC often quoted the Aspen Area Community Plan as the basis for their action. The AACP recommends the development of Character Guidelines to help new development fit in with neighborhoods and it recommends review of current floor area ratios for the R-6 zone district. Both the HPC and the Planning and Zoning Commission held several worksessions in June of 1994. The focus of those meetings were to determine the best approach to prevent further erosion of Aspen's community character through residential development which is incompatible with the surrounding neighborhood and which destroys the pedestrian scale of neighborhoods. Several ideas were passed to the Council at the beginning of July. Council supported further analysis of the Land Use Code although some members did not believe it was a priority and/or a problem. The Commission, by Resolution, recommended to Council an interim overlay zone district over the entire City excluding the R-15B zone district and pertaining to only residential development. Council adopted the overlay zone district August 24, 1994. II. The overlay zone district required all residential development which exceeded 85% of the allowable floor area to undergo a special review process. The Special Review was based upon the Neighborhood Character Guidelines and administered by a separate committee comprised of Commission members and HPC members. Since the interim review began in September of 1994, 29 cases have been reviewed by the Committee. Of those 14 were mandatory compliance with the review. Staff believes that approximately, 80% of the non -mandatory compliance cases, those over 9,000 square feet were found to be inconsistent with the Guidelines. There were several common problems why proposal were found in noncompliance: * primary entrance not facing the street * 2 story windows on the street *,not breaking the mass into modules * mansard/shallow pitch roofs * no accessory structures to help break down the mass * lack of pedestrian scaled entrances * no variation in roof height * long, unbroken wall planes * no inflection to smaller adjacent structures * lightwells facing the street * large volumed spaces * oversized garages facing the street III. During this interim overlay review process, staff has been working to amend the land use code in an attempt to reduce and/or discourage the type of residential design features that are believed to be out of character with Aspen's neighborhoods. As part of this work the City conducted a Design Symposium inviting architects from around the nation to address the local architectural and development community to discuss Aspen's design issues. Several consensus statements were one of the results of that meeting: * Develop Neighborhood Streetscape/Landscape Plan for each area. * Redefine the present requirements for Floor Area Ratio -- simplify the calculation and lower the FARs. * Maintain and define a loose building envelope. * Review the effects of the auto on our code. * Develop incentives to support desired outcomes in urban design. * Focus on building fronts in developing specific and objective guidelines. * Develop an education program. The Community Development Department also hired a consultant, Dan Solomon, who is experienced in developing design standards to help address issues of inappropriate urban design. Mr. Solomon has developed submission requirements for an administrative checklist that becomes a tool to implement recommended design standards. Mr. Solomon also recommended several revisions to the existing methods of development review in the City. The checklist is intended to apply to all residential development. It will be used by an applicant when preparing for a building 3 permit application that the standards submitted plans. include the method heights. and later will be reviewed by staff to ensure found on the checklist are consistent with the Recommended revisions to the Land Use Code of calculating floor area ratio, volume and Using the consultant's recommendations, staff enlisted five local architects to perform case studies. The architects were presented with differently sized parcels and zone districts, and asked to develop a residential design using existing code standards at full FAR, existing code standards at an 85% maximum FAR, and according to the recommendations from Mr. Solomon. In the third scenario, the architects were also to use the checklist in anticipation of a submittal for building permit. The architects' work was reviewed and filmed by staff and critiqued by the other architects. The video and recommended changes to the initial Solomon draft were sent to Solomon for revisions. Together with the Design Symposium information, Mr. Solomon's work, and extensive input from the architectural community and other residents, staff has developed these code changes intended to create incentives to encourage the desired design outcomes as identified in the past nine months, and hopefully simplify the code somewhat. Generally, the proposals are an attempt to address the following problems which have been identified during our work with local architects and the consultants: * Inconsistent Street Frontage * Erosion of Pedestrian Scale * Dominant Garages * Conflicting Scale: New Building and Neighbors * Awkward Areaways and Lightwells * Overscaled Buildings * Overscaled Entries PROPOSED CODE AMENDMENTS: I. Residential Design Standards and Checklist/Submission Requirements - According to the consultant, Dan Solomon, the above problems may be addressed without the institution of a design review committee. Residential Design Standards, structured by the existing urban context of the community, may be codified and applied to development in order to discourage inappropriate urban design. As a tool to implement the Design Standards a succinct, simple, and precise "checklist", has been developed for other communities to great success. Mr. Solomon has prepared many such sets of design standards with accompanying checklists, and recommends the use of the design standard/checklist format for residential development in Aspen. rI WA Prior to a property owner submitting plans for a building permit, staff would conduct a pre -application conference to inform the applicant of all pertinent reviews and introduce the checklist and the submission requirements for the checklist. An application for development would then by compared, by staff at an administrative level, to the checklist to find consistency. Please refer to the recommended Residential Design Standards and Checklist, Exhibit A, which will be used for all residential developments whether development is new, total redevelopment, or an addition. II. Appeal - If for any reason the submitted application does not comply with the checklist, the applicant would be required to amend the submittal or the applicant may appeal staff's finding to an appeal board. It is staff's intention that the appeal board function similarly to the current Interim Overlay Review board. The board would be convened on an as needed basis every second Tuesday of the month. The Board will be comprised of HPC and P&Z members. Unlike the current review system where only parcels 9, 000 sq. ft. or less must comply with the Board's review, all items taken to the Board must comply with the Board's recommendation. III. Code Revisions - In addition to creating Residential Design Standards and an administrative checklist, staff proposes changes to the existing Land Use Code. IIn an attempt to simplify the code, which has been a common complaint, staff also recommends a consolidation of the formulas applicable to residential review into one section in the code. Toward that end, a new section in the Code - Article 7. Division 3. Residential Design Standards, is recommended to house all the design standards and processes that are being created by this amendment. For a review of the proposed language changes please refer to Resolution. Staff will thoroughly review all proposals at the meeting. Proposed amendments are indicated in bold, and deleted language is in strikeeidt. Please refer to the Text Amendment review criteria, Exhibit B. ALTERNATIVES: Staff recommends the creation of Residential Design Standards to be administered by a checklist for all residential development, an appeal board for those projects that are found to be inconsistent with the checklist, and overall amendments to the Code that affect residential design in Aspen. However, staff and the community have explored other alternatives that the Commission may also wish to consider. G I. Do Not Amend - Pro - Many people in the development community and staff are familiar with the existing code. Changes to code language, FAR calculations and the addition of another review board may impose a particular burden on future development. Con - Continuing with the status quo will permit continuation of inappropriate design patterns in Aspen's neighborhoods that have become a concern to many Aspen residents. As described in the language of Ordinance 35 adopting the interim overlay zone district: "recent residential development in Aspen represents a far more grand scale and suburban image than the traditional character of Aspen and is creating a new context for the neighborhoods in the City of Aspen which has little relationship to what they once were." II: Reduce the Allowable Floor Area Ratios by 15% - Pro - An across the board reduction in FAR is technically a simple procedure which assists in reducing the mass that could be developed on a given parcel. Con - A reduction of 15% is not enough to produce a noticeable change while ignoring some of the design mistakes that are made, whether at 100% FAR or 85% FAR. As one resident remarked in a public hearing, small buildings can be just as ugly as large buildings. This type of reduction also places a greater hardship on smaller parcels. III. Reduce the Allowable Floor Area Ratios by 15% and Implement Design Review for All Residential Development - Pro - This alternative represents the greatest change to the current and interim system. A reduction in FAR and Design review goes to the heart of the neighborhood character issue. Design review would ensure that the character of the neighborhood is definitely being considered during design and the reduction in FAR would result in smaller homes. Con - Mandatory design review would require development of accurate neighborhood character guidelines for each neighborhood. In non- traditional neighborhoods these guidelines may be difficult, but not impossible to craft, thus requiring a significant amount of staff time. In addition, mandatory review will require a very active review board and staff time to work with the board. Staff already works with up to nine review boards. IV. Require Design Review for Proposals that Exceed 85% of Allowable Floor Area Ratios as currently Defined - 6 Pro - Residents interested in developing or redeveloping their property would not be pressured into developing 100% of allowable floor area because future additions on or potential buyers would be able to expand or redevelop at the maximum floor area via the review. Several residents expressed that the pressure to build to the maximum exists because one never knows when the "city" will change the rules. Many believe that this has led to oversized homes beyond a resident's needs. The design review would ensure that neighborhood character issues were considered and all property owners would have the ability to achieve maximum floor area via the design review. During the interim review period, the design review process was considered by several participants/applicants, to have been a very positive review. Many applicants affirmed that the end result was much preferred to the original design proposed. Because review would not be required until a project exceeded 85% of FAR, staff anticipates that the amount of reviews and time spent on this process would be less than in the Alternative III scenario. Con - Staffing and implementing the process would still require significant staff time. Review would have to be mandatory for all residential parcels. This alternative creates an additional layer of review for homeowners. V. Reduce the Allowable Floor Area Ratios by 15% and Utilize Proposed Design Standards - Pro - The proposed design standards are intended to reduce and hopefully prevent inappropriate urban design in Aspen. The reduction in allowable FAR would further reduce the sense of the "monster home" on residential parcels, especially on smaller lots and non -conforming lots of record. Several members of the architectural community have stated that the ratios are irrelevant and they can comfortably produce a good design with any ratio. Con - Members of the community have argued that the allowable ratios are not the problem, it is design. CONTINUED WORK: Having extensively analyzed the Land Use Code, held numerous meetings with many residents and architects of the community, and having researched other communities' efforts in design guidelines and other means to encourage appropriate mass and scale, staff recognizes that more work could be undertaken in this area. Specifically, staff will continue to develop an education program and create an informational guide for potential 7 VI developers/architects that discusses neighborhood character guidelines, historical development patterns, etc. Based upon a recommendation from the Design Symposium, staff will work to develop streetscape/landscape plans that guide development into a more cohesive and sensitive manner with existing vegetation and better pedestrian streetscape amenities. RECOMMENDATION: While these Design Standards and FAR revisions may not address all the issues which have been identified through our public process. Staff believes they represent the most appropriate response to these issues at this time. Staff recommends adoption of the code amendment and Design Standards based upon the consultant's "Draft Recommendations for Residential Design." RECOMMENDED MOTION: "I move to adopt Resolution 95- , adopting Residential Design Standards and related text amendments as recommended by the "Draft Recommendations for Residential Design."

Development Review Standards, of Chapter 24 of the Municipal Code of the City of Aspen, Colorado, is hereby amended, which new text shall read as follows: ARTICLE 7. DEVELOPMENT REVIEW STANDARDS DIVISION 1. GENERAL The purpose of Article 7 is to establish the substantive development review standards for development applications. They include: • Permitted Uses (Article 7, Division 2), * Residential Design Standards (Article 7, Division 3) • Conditional Uses (Article 7, Division 4), 11 • Development Subject to Special Review (Article 7, Division 5), • Development in an Environmentally Sensitive Area ( ESA) (Article 7, Division 6 ) , • Development or Demolition in H, Historic Overlay Districts or of a Historic Landmark (H)(Article 7, Division 7), • Designation of a (H) Historic Overlay District or a Historic Landmark (Article 7, Division 8), • Specially Planned Areas (SPA)(Article 7, Division 9), • Planned Unit Developments (PUD) (Article 7, division 10) , • Subdivision review (Article 7, division 11), and • Amendment to the text of this chapter or the Official Zone District Map (Article 7, Division 12). DIVISION 3. RESIDENTIAL DESIGN STANDARDS Section 7-301. General. A. Purpose. The purpose of the following design standards are to preserve established neighborhood scale and character, and to ensure that Aspen's streets and neighborhoods are public places conducive to walking. Front facades and their relationship to the street establish the character of a neighborhood. The area surrounding a home's front door creates a transition between the private life of a dwelling and the public realm. A one story architectural projection emphasizing the entry provides an appropriate domestic scale for a private residence. Street facing porches, loggias, and balconies provide outdoor living space, further animating the streetscape. Windows establish a hierarchy of spaces within --larger, formal windows denoting public areas, smaller ones suggesting private space. Consistent front setbacks define the space of the street. C. Applicability. All residential development in the City of Aspen requiring a building permit from the City of Aspen shall comply with the residential design standards as suggested by the Administrative Checklist unless otherwise granted a variance by the Design Review Board of Appeal as established in Article 4, Division 5 of this Chapter. D. Application. A development application for residential development shall consist of an application for a Development Order pursuant to Section 6-202 and Section 7-302. The Development Order application shall be submitted to the Community Development Department. E. Exemptions. No application for a residential development order shall be exempt from the provisions of this Section unless the Planning Director determines that the proposed 12 development: a. adds floor area but does not alter the exterior of an existing structure; and b. is any addition or remodel of an existing structure that does not change the exterior of the building. Section 7-302. Procedure. Pursuant to Section 6-201. Preapplication Conference, an applicant shall conduct a pre -application conference with staff of the planning division of the Community Development Department. At that conference the planner shall provide an application packet which shall include the Submission Requirements of the Administrative Checklist and any other pertinent land use review material. Pursuant to Sections 6-202, 6-203 and 6-204, an applicant shall prepare an application for review and approval by staff. In order to proceed with additional land use reviews or obtain a Development Order, staff shall find the submitted development application consistent the Residential Design Guidelines. If an application is found to be inconsistent with any item of the Residential Design Guidelines the applicant may either amend the application or appeal staff's finding to the Design Review Board of Appeal pursuant to Article 4. Division 5. Design Review Board of Appeal. Section 7-303. Administrative Checklist Director of Community Development shall promulgate a checklist for use by applicants and community development staff in identifying the approvals and reviews necessary for issuance of a development order for an application that is consistent with the Residential Design Guidelines. Section 7-304. Residential Design Standards 1. Building Orientation a. The orientation of the principal mass of all buildings must be parallel to the streets they face. On corner lots, both street -facing facades of the principal mass must be parallel to the road. b. All single family homes, townhouses and duplexes must have a street -oriented entrance and a street facing principal window, except townhouses and accessory units facing courtyards or gardens, where entries and principal windows should face those 13 2- features. On windows should block length. corner lots, entries and principal face whichever street has a greater 1. A street oriented entrance requires that at least one of the following two conditions are met: a. The front entry door is on the street facade b. A covered entry porch of 50 or more square feet is part of the street facade. 2. A street facing principal window requires that the largest window or group of windows of a living room, dining room or family room face the street. C. For single family homes and duplexes with attached garages or carports, the width of the house must be at least five feet greater than the width of the garage along its street facing frontage. The garage must be set back at least 10 feet further from the street than the house. d. Multiple unit residential buildings must have at least one street -oriented entrance for every four units. Front units must have a street facing principal window. 2 Building Elements a. All residential buildings must have a one-story street facing element the width of which comprises at least 20% of the building's overall width. 3. Build -To Lines a. If 75 % or more of the residential buildings on the blockface where a project is to be located are within 2 feet of a common front setback line, a minimum of 60 % of a proposed project s front facade must also be within 2 feet of that front setback. b. Corner sites are of particular importance in the definition of street frontages. Therefore on corner sites where fewer than 75% of the residential buildings on the blockface are located within 2 feet of a common setback line, a minimum of 60% of at least one of the street frontages of a proposed project s front facade must be located within 2 feet of the minimum setback. 4. Primary Mass 14 a. A primary mass is a building volume for which two of the following three characteristics do not vary: plate height, ridge height, wall plane. The floor area of a primary mass in excess of 70% of total allowable FAR shall be multiplied by 1.25. 5. Inflection a. If the street frontage of an adjacent structure is one story in height for a distance more than twelve feet on the side facing a proposed building, then the adjacent portion of the proposed building must also be one story in height for a distance of twelve feet. 1. If the adjacent structures on both sides of a proposed building are one story in height, the required one story volume of the proposed building may be on one side only. 2. If a proposed building occupies a corner lot, and faces an adjacent one story structure, the required one story element may be reversed to face the corner. 6. When calculating floor area ratio the following formulas and definitions shall be used: a. Accessory dwelling unit or linked pavilion. For the purposes of calculating floor area ratio and allowable floor area for a lot whose principal use is residential, the following shall apply: The allowable floor area of an attached accessory dwelling unit shall be excluded up to a maximum of two hundred fifty square feet of allowable floor area or fifty percent of the size of the accessory dwelling unit whichever is less.; a d-tehAn accessory dwelling unit separated from a principal structure by no less than fifteen (15 ) feet with a maximum footprint of four hundred fifty square feet shall be calculated at fifty percent exeluded up te a maximufft ef three hundred fifty square feet of allowable floor area up to a maximum of 700 square feet. Any element linking the principal structure to the accessory unit may be no more than one story tall, six feet wide, and ten feet long. This floor area exclusion provision only applies to accessory dwelling units which area e hunelre pereent abeve natural grade and are subject to review and approval by the planning and zoning commission pursuant to conditional use review and approval, section 7-304 of Chapter 24 of this Code. b.

The height of a building shall be the maximum pens ib distance measured vertically at right ang from the natural undisturbed greund slepe and natural grade or finished grade, whichever is lower, to the top of a flat, er- mansard or other roof with a slope of less than 3:12. For roofs with a slope form 3:12 to 7:12, height shall be measured vertically from the natural or finished grade, whichever is lower, to or the mean height between the eaves and ridge of a gable, hip, gambrel or similar pitched roof. For roofs with a slope of 8:12 or greater, height shall be measured vertically from the natural or finished grade, whichever is lower, to the point one-third (1/3) the distance between the eaves and the ridge.

Lot area means the total horizontal area within the lot lines of a lot. When calculating floor area ratio, lot area shall include only areas with a slope of less than 20%. In addition, half (.50) of lot areas with a slope of 20-30 % may be counted towards floor area ratio; areas with slopes of greater than 30% shall be excluded. Also excluded for the purpose of floor area calculations is that area beneath the high water line of a body of water and that area within an existing or proposed dedicated right-of-way or surface easement, but shall iIncluded are any lands dedicated to the City of Aspen or Pitkin County for the public trail system, any open irrigation ditch, or any lands subject to an above ground or below ground surface easement such as utilities that do not coincide with road easements.

ATTEST: Sharon Carullio Deputy City Clerk Bruce Kerr, Chairman Aspen Planning and zoning Commission 20 NSULTANT'S DRAFT RECOMMENDATIONS RESIDENTIAL DESIGN ASPEN, COLORADO SOLOM ON ARCHITECTURE & URBAN DESIGN 3 May 1995 CONSULTANT'S DRAFT RECOMMENDATIONS RESIDENTIAL DESIGN ASPEN, COLORADO The following text contains our recommendations for the redrafting of residential design standards for Aspen. It is our hope that these recommendations will be helpful to the Aspen Planning Department and to the architects and other citizens who have donated time and energy to this subject. In submitting this material we must emphasize that the specific provisions contained in this draft are the product of a brief and limited study and have not yet been subjected to the rigorous testing which we believe is an important component of ordinance writing. The conceptual framework, format and intentions of this work should address the issues that have been identified by City of Aspen planning staff and citizens. Various specific provisions and numerical standards will almost certainly require further adjustment as they are tested through use. Daniel Solomon Kevin Powell CONSULTANTS DRAFT RECOMMENDATIONS 1. OVERVIEW In January of 1993, the City of Aspen adopted a Community Plan. This plan proposed a framework for action predicated on eight specific goals. Outlined below are design standards and zoning code provisions intended to implement four of these eight goals: (1) to increase resident housing; (2) to encourage a more balanced permanent community; (3) to enhance pedestrian systems; (4) to encourage environmentally sustainable development patterns. The text below identifies seven specific residential design issues or problems that affect the quality of town life in Aspen. Prescriptive requirements, described so that compliance can be easily measured, respond to each issue. Any appeal for exemption from these measures should simply and succinctly identify why, if granted, the exception would (1) yield greater compliance with the goals of the Aspen Area Community Plan and (2) more effectively address the issue or problem a given standard or provision responds to.

ASPEN RESIDENTIAL DESIGN STANDARDS The Design Standards which follow are presented as revisions to Aspen's Land Use Regulations. We have described them in this manner to make clear their modification of existing code. Sec. 5-200-1. All Districts: Relation of Buildings to Streets. A. Intent. The purpose of the following design standards are to preserve established neighborhood scale and character, and to ensure that Aspen's streets and neighborhoods are public places conducive to walking. Front facades and their relationship to the street establish the character of a neighborhood. The area surrounding a home's front door creates a transition between the private life of a dwelling and the public realm. A one story architectural projection emphasizing the entry provides an appropriate domestic scale for a private residence. Street facing porches, loggias, and balconies provide outdoor living space, further animating the streetscape. Windows establish a hierarchy of spaces within --larger, formal windows denoting public areas, smaller ones suggesting private space. Consistent front setbacks define the space of the street. B. Standards 1. Building Orientation a. The orientation of the princpal mass of all buildings must be parallel to the streets they face. On corner lots, both street -facing facades of the princpal mass must be parallel to the road. b. All single family homes, townhouses and duplexes must have a street - oriented entrance and a street facing principal window, except townhouses and accessory units facing courtyards or gardens, where entries and principal windows should face those features. On corner lots, entries and principal windows should face whichever street has a greater block length. 1. A street oriented entrance requires that at least one of the following two conditions are met: a. The front entry door is on the street facade b. A covered entry porch of 50 or more square feet is part of the street facade. 2. A street facing principal window requires that the largest window or group of windows of a living room, dining room or family room face the street. c. For single family homes and duplexes with attached garages or carports, the width of the house must be at least five feet greater than the width of the garage along its street facing frontage. The garage must be set back at least 10 feet further from the street than the house. d. Multiple unit residential buildings must have at least one street -oriented entrance for every four units. Front units must have a street facing principal window. Page 3 2 . Building Elements a. All residential buildings must have a one-story street facing element the width of which comprises at least 20% of the building's overall width. 3. Build -To Lines a. If 75% or more of the residential buildings on the blockface where a project is to be located are within 2 feet of a common front setback line, a minimum of 60% of a proposed project's front facade must also be within 2 feet of that front setback. b. Corner sites are of pariticular importance in the definition of street frontages. Therefore on corner sites where fewer than 75% of the residential buildings on the blockface are located within 2 feet of a common setback line, a minimum of 60% of at least one of the street frontages of a proposed project's front facade must be located within 2 feet of the minimum setback. 4. Primary Mass a. A primary mass is a building volume for which two of the following three characteristics do not vary: plate height, ridge height, wall plane. The floor area of a primary mass in excess of 70% of total allowable FAR shall be multiplied by 1.25. 5. Inflection a. If the street frontage of an adjacent structure is one story in height for a distance more than twelve feet on the side facing a proposed building, then the adjacent portion of the proposed building must also be one story in height for a distance of twelve feet. 1. If the adjacent structures on both sides of a proposed building are one story in height, the required one story volume of the proposed building may be on one side only. 2. If a proposed building occupies a corner lot, and faces an adjacent one story structure, the required one story element may be reversed to face the corner. Sec 3-101. Suggested Revisions to Text p. 1582, 3-101.13 Decks, balconies porches, loggias and stairways. The calculation of the floor area of a building or a portion thereof shall not include decks, balconies, stairways, terraces and similar features, even though these areas are riot surrounded by exterior walls or enelosed, when thege feature are above natural grade mid when unless the area of such these features is greater than fifteen percent of the maximum allowable floor area of the building. Porches, defined as uninsulated, unheated areas under a roof, bounded on at least one side by the exterior wall of a living space and open on at least two sides to the outdoors shall not be counted towards FAR.

No portion of a driveway to a garage shall be below the natural grade within the required front setback. All portions of a garage, carport or storage area parallel to the street shall be recessed behind the front facade a minimum of ten (10) feet. Garages below natural grade, garages with a vehicular entrance width greater than twenty four feet, and garages with a vehicular entrance width greater than 40% of their front facade shall meet one of the following conditions: (a) All elements of the garage shall be located within fifty feet of the rear lot line or (b) All elements of the garage shall be located farther than one hundred fifty feet from the front lot line, or (c) the vehicular entrance to the garage shall be perpendicular to the front lot line An element linking a detached garage to the principal structure shall not be included in the calculation of floor area provided that the linking structure is no more than one story tall, six feet wide. p.1583, 3-101-D Subgrade areas. The area of any story , naturM grade whose top plate is a maximum of eighteen inches above natural or finished grade, whichever is lower, at any point along the perimeter of the building shall be excluded from floor area calculations. For any story which is partly above and partly below natural or finished grade whichever is lower, a calculation of the total volume of the story which is above and which is below grade shall be made, for the purpose of establishing the percentage of the area of the story which shall be included in floor area calculations. This calculation shall be made by determining the total percentage of the perimeter wall area of the story which is above natural or finished grade, whichever is lower, which shall be multiplied by the total floor area of the subject story, and the resulting total shall be that area which is included in the floor area calculation. All areaways, lightwells and/or stairwells on the street facing side(s) of a building must be entirely recessed behind the vertical plane established by the building's facade.

Page 9 EXHIBIT B EXHIBIT B Pursuant to Section 24-7-1102 the standards of review for an amendment to the Official Zone District Map are as follows: a. Whether the proposed amendment is in conflict with any applicable portions of this chapter. RESPONSE: The proposed amendments will affect many portions of Chapter 24. The proposed amendments are an attempt to strengthen existing residential review and provide a more accurate review of development related to scale and massing. b. Whether the proposed amendment is consistent with all elements of the Aspen Area Community Plan. RESPONSE: The Aspen Area Community Plan is a character based plan. The erosion of the neighborhood context by new development has had an alarming effect upon the City's review boards and many Aspen residents. The development trends were also inconsistent with the goals of the AACP. Specifically, the AACP recommends that the allowable floor area ratios for the R-6 zone district be reviewed to determine the continued appropriateness for the neighborhood. The AACP also recommends that the planning staff assist and encourage neighborhoods not located within historic districts to develop their own set of Character Guidelines to assist new development to fit within the context of each neighborhood's character. After nine months of work, staff believes that creation of Residential Design Standards and required compliance at the administrative level will enable property owners to remain creative in their designs yet help prevent the inappropriate residential design that was being experienced in Aspen's neighborhoods. C. Whether the proposed amendment is compatible with surrounding Zone Districts and land uses, considering existing land use and neighborhood characteristics. RESPONSE: The proposed amendments will affect all residential development in the City of Aspen. d . The effect of the proposed amendment on traffic generation and road safety. RESPONSE: The proposed amendments are directed toward mass and scale of residential structures. The amendments will reduce the required amount of on -site parking with a possible result of residents parking more cars on the street. However, most neighborhoods are within a parking permit area and a limited number of resident permits are issued per household and the amendment does H not prevent a property owner from providing more parking than is required. e. Whether and the extent to which the proposed amendment would result in demands on public facilities, and whether and the extent to which the proposed amendment would exceed the capacity of such public facilities, including but not limited to transportation facilities, sewage facilities, water supply, parks, drainage, schools, and emergency medical facilities. RESPONSE: These proposed amendments will not increase the demand on the public facilities other than the Community Development Department and City Clerk's office. The proposed amendments require review at the administrative level, creating more information that staff will be required to impart to an applicant. However, a pre -application conference is already a standard practice in the office and review of a submitted application is a requirement prior to scheduling other land use review. In is anticipated that the checklist review can be folded into the existing process. Review by the Appeal Board will require additional staff time. However, use of the Board should be minimal after architects become familiar with the Design Standards. f. Whether and the extent to which the proposed amendment would result in significantly adverse impacts on the natural environment. RESPONSE: The proposed amendments are intended to guide residential development toward a higher standard of design which will have positive impacts on the environment of Aspen's neighborhoods. g. Whether the proposed amendment is consistent and compatible with the community character in the City of Aspen. RESPONSE: The traditional identity of the character of Aspen's neighborhoods is being threatened by development that is occurring out of context and scale with the surrounding homes. The proposed amendments are an attempt to prevent further erosion of traditional streetscape and scale of the neighborhoods, whether in the historic neighborhoods such as the West End or newer ones such as Cemetery Lane. h. Whether there have been changed conditions affecting the subject parcel or the surrounding neighborhood which support the proposed amendment. RESPONSE: More and more development is occurring out of scale and character with Aspen's neighborhood. Use of Residential Design Standards and compliance with the checklist will hopefully engender a thought process in design that will result in homes that are more �a in character with the Aspen community and the specific neighborhood where potential development is to occur. i. Whether the proposed amendment would be in conflict with the public interest, and is in harmony with the purpose and intent of this chapter. RESPONSE: The intent of the Design Quality and Historic Preservation section of the AACP is "to ensure the maintenance of character through design quality and compatibility with historic features." The proposed amendments to the Code are consistent with that section of the AACP and are intended to preserve the public interest by maintaining the unique and special character of Aspen's neighborhoods by guiding new development. 3 SV. fl . MEMORANDUM TO: Aspen Planning and Zoning Commission FROM: Leslie Lamont, Deputy Director RE: L'Auberge Conditional Use Review- Continued Public Hearing DATE: May 9, 1995 ----------------------------------------------------------------- ----------------------------------------------------------------- SUMMARY: The applicants propose to expand their existing lodge operation and have proposed a text amendment to enable a lodge as a conditional use in the Office zone district. The Commission approved the text amendment for a lodge in the office zone district, however at staff's request tabled the conditional use review in order for the applicant and staff to continue to work on the conditional use application. Staff recommends approval of the conditional use L'Auberge. The applicants are seeking several variance from the Board of Adjustment for the existing structures and the proposed cabins: Existing Proposed Front 10 ft. 1.5 ft. Rear 15 ft. 1.5 ft. Side 5 ft. 0 Between Bldgs. 10 ft. 3 ft. A hearing date has been established for May 25. The applicants have also received final HPC review on April 26, 1995. APPLICANTS: ALH Holding Company represented by Gibson and Reno Architects and Gideon Kaufman, Attorney LOCATION: 435 West Main Street, Aspen Colorado ZONING: Office (0) APPLICANT'S REQUEST: A conditional use review for the L'Auberge lodge in the office zone district. REFERRAL COMMENTS: Please find the referral comments, exhibit A. STAFF COMMENTS: I. Conditional Use - Staff, for the April 18 meeting, recommended tabling conditional use review primarily due to the insufficient utility/services plan. However, the various utility/service entities have since met with the applicant's representatives and have identified changes to the service plan in order for the utilities to sign -off on the plan. A revised plan shall be approved prior to Council's allocation of the GMQS allotments. In addition, the applicant has revised their site plan. A curb cut was eliminated and one parking place was deleted from the plan in order to provide better parking and auto circulation. For a review of the conditional use standards please see Exhibit B. II. Parking - The office zone district requires 3 spaces/1000 square feet of office space and does not list a requirement for a lodge. Last month when the Commission reviewed the text amendment for a lodge in the office zone district, language regarding parking for a lodge was not included. Therefore staff would recommend that the Commission also recommend to Council, the administrative body that will ultimately approve a text amendment, a parking requirement for lodges in the office zone district. Staff would suggest consistency with other lodge zones which is .7/bedroom of which .2 may be reduced via a payment in lieu. RECOMMENDATION: Staff recommends approval of the conditional use for the L'Auberge Lodge with the following conditions: 1. Prior to the lodge GMQS allocation by the City Council, the applicant shall submit a revised service utility plan that has been reviewed and approved by the ACSD, Rocky Mt. Natural Gas, and the water, electric, and engineering departments. 2. Any costs for new public services that must be installed or upgraded shall be borne by the applicant on a partial or full basis depending upon the specific agency's requirements. 3. Prior to the issuance of any building permits, the applicant shall file restrictions against future installation of fireplaces and woodstoves with the Environmental Health Department. 4. Prior to the issuance of any building permits, the applicant shall submit a fugitive dust control plan, to be reviewed and approved by the Environmental Health Department. 5. Prior to the issuance of any building permits the applicant shall submit a revised site plan that includes: a. all transformer and utility easements; b. a detailed drawing of the area for all service/trash and recycling areas; c. proposed and city specified sidewalks on 3rd and 4th streets between Main Street and the alley; 2 d. a revised parking plan to be reviewed and approved by the engineering and planning staff; e. elimination of the curb cut adjacent to the manager's residence. 6. Prior to the issuance of any building permits the applicant shall submit a detailed landscape plan approved by the Parks Department. 7. Prior to the issuance of any building permits: a. tree removal permits and a mitigation plan for removing or relocating any trees 6" in caliper or greater shall be required from the Parks Department and any trees proposed to be saved shall be protected during construction, including no digging or over digging within the drip line; b. the applicant shall enter into an agreement with the Engineering Department to construct curb and gutter in the future; C. the applicant shall pay all applicable water and sewer tap fees; and d. the applicant shall file the appropriate deed restrictions with the Housing Office for the deed restricted dwelling unit. 8. Any irrigation system that is installed shall be incompliance with the Water Conservation Code. 9. As required in Section 24-7-1004 C.4.f, the applicant shall maintain the historic runoff patterns that are found on the site and shall correct any runoff or erosion problems that currently exist on the site. 10. The applicant shall agree to join any future improvements districts which may be formed for the purpose of constructing improvements in the public right-of-way. 11. All lighting fixtures will face downward and be shielded to eliminate the potential for glare or nuisance to neighboring properties. Lighting along the walkways will be low to the ground (approximately 3' in height) and shielded. 12. All work in the alley and public right-of-way shall require a permit from the Streets Department. 13. During construction, noise cannot exceed maximum permissible sound level standards, and construction cannot be done except 3 between the hours of 7 am. and 10 p.m. 14. Early warning devices and fire extinguishers shall be provided in all cabins and the manager's residence. 15. If the applicants intend to use the ditch for irrigation, a utilization plan must be reviewed by the Parks and Water Departments which may include a raw water agreement. The agreement must be signed prior to the issuance of any building permits. 16. Prior to the issuance of any building permits the applicant shall apply for an encroachment license. 17. This conditional use approval is conditioned upon successful completion of the variance request process, Council approval of the text amendment, and Council allocation of the lodge allotments. 18. The applicant acknowledges Municipal Code sidewalk maintenance requirements for all sidewalks abutting the applicant's property. These property owner obligations include timely snow removal as provided for in Section 19, Article VIII, and sweeping and maintenance against hazardous conditions as provided for in Section 19, Article IV. 19. All material representations made by the applicant in the application and during public meetings with the Planning and Zoning Commission and joint GMQS Commission meeting shall be adhered to and considered conditions of approval, unless otherwise amended by other conditions. RECOMMENDED MOTION: "I move to approve the conditional use for the LIAuberge Lodge with the conditions outlined in staff s memo dated May 9, 1995." "I move to recommend to Council the addition of a parking requirement for lodges in the office zone district as stated in staff's memo dated May 9, 1995." ATTACHMENTS: A. Referral Comments B. Conditional Use Standards C. Landscape Plan El Exhibit "A" MEMORANDUM TO: Leslie Lamont, Deputy Planning Director FROM: Amy Amidon, Historic Preservation Officer RE: 435 W. Main Street- L'Auberge, HPC review DATE: April 13, 1995 Overall, there was a lot of support for the design of the project and the applicant's effort to respect the scale of the existing cabins on the site. Some concerns were expressed about the project' s relationship to the street and the "interioriz ing" of the open space. Some members felt that there should be more of a linkage between the project and the streetscape. The landscape plan and significant amount of parking were also cited as issues to be discussed further. The conditions made at conceptual approval were: 1. That the cabin unit 22 is removed and 21 is set back 10 feet from the property line. 2. That all new construction be differentiated in a very positive and hopefully contemporary way from the existing structures. 3. That the detailing of the existing cabins not be significantly altered. 4. As many parking spaces as possible can be surfaced with grass- crete or a similar porous and non -hard surface. 5. Study the Main Street elevations, especially the story and a half massing and looking at the opportunities for combining buildings. To: Leslie Lamont From: Bill Earley Date: 3/29/95 Subject: L'Auberge 1994 Tourist Accommodations GMQS I have reviewed the submitted information and have the following comments; 1. No load information on the electric demand is provided so I cannot access the impacts on our system but I do not think it will be a problem. 2. We have three phase and single phase power available in the alley. There is an existing 25KVA single phase transformer in the alley that provides electric service to -this block. We may have to up size this unit. This cost would be paid by the developer. 3. Streetlighting in this area is our standard design with doubles on .Main St. and overheads at the intersections of Hopkins and 3rd and 4th. 57spen ConsoPio(aleo(c5anilalion!Z)islricI 565 North Mill Street Aspen, Colorado 81611 Tele.

RE: Sewer Service Configuration, L' Auberge : Conditional Use Permit Dear Jay, I am writing this letter in response to your letter dated 4- 14-95 requesting a variance to the Aspen Consolidated Sanitation District Rules and Regulations requiring individual structures to have individual sewer service lines to the District main line. As we have discussed, I cannot grant a variance from this section of our Rules and Regulations; only the Aspen Consolidated Sanitation District Board of Directors can grant a variance from our Rules and Regulations. The neat available Board of Directors meeting is May 2, 1995. Please contact Mr. Bruce Matherly at 925- 3601 as soon as possible so that he can schedule a spot on the agenda for you at this meeting. Since this project is unique in that the applicant is endeavoring to build small structures resembling the existing cabins on this site as requested by the Historic Preservation Committee and since there may not be an adequate utility corridor to provide a main line extension, our Board of Directors may entertain discussions allowing a well engineered internal acllpc+-cn system designed by a registered professional engineer providing: - 1. The applicant would commit to working with the District through -your office to design a professional internal collection system that would be acceptable to the District and the District's consulting engineer that would be owned and maintained by the applicant and execute shared service agreements for this private system. 2. That the applicant will address the concerns as stated in the enclosed letter dated 4-6-95 to Leslie Lamont, Planner -City of Aspen, since the referral is a "Conditional Use Review" and since this referral is the last time that the District may be able to comment on this application 3.

Leslie Lamont, Planning Office THRU: George Robinson, Parks Director FROW Rebecca Baker, Parks Department DATE: April 10, 1995 RE: L'Auberge 1994 Tourist Accommodations GMQS, Code Amendment & Conditional Use Review We have reviewed the application submitted by ALH Holding Company and offer the following comments and concerns. In regards to the GMQS criteria, providing transportation alternatives (section 2 (i)), the applicant discusses the newly constructed sidewalk and ditch that parallel the property along Main St. The applicant should be requested to contribute to the cost of the sidewalk considering their development application is being submitted less than a year after the new sidewalk construction and the new sidewalk enhances their property development considerably due to the growth in services. The development should also construct sidewalk along 3rd and 4th Streets as identified in the Pedestrian Plan. The description of the ditch or watercourse described in section 2(i) states the "Lodge maintains and irrigates this watercourse and greenway along the new public sidewalk". The ditch is a City ditch and if irrigating is proposed to be done from the ditch the Parks Department would need to see a plan prior to utilization of the water from this ditch. Additionally, if the ditch is proposed to be culverted to accommodate the new driveways, a 12 inch PVC pipe (nQ corrugated metal pipe) is required to be installed. The proposed relocation of two scotch pines need to be evaluated by an expert tree mover. The proposed re -locations may not work in the space provided. It is also inadvisable to propose to locate spas underneath coniferous trees. The fallen needles create problems for the spa mechanical systems and can be hazardous to bare feet. The number of Aspen trees proposed to be removed may require an extensive mitigation plan. The majority of the mitigation should take place on site. We would request the applicant submit a detailed landscape plan stating tree removals and a replacement plan. If the development cannot accommodate the total mitigation, then we would like to know what the applicant proposes, ie. if they would like to donate trees to the City of Aspen, etc. The final comment on the project is in regards to the trees in the Main St. right-of-way. These trees are not shown on the existing site plan and may be an over site, but should be noted that they are not to be removed or damaged by construction. .s MEMORANDUM To: Leslie Lamont, Planning Office From: Chris Chiola, Environmental Health Department- Au Through: Lee Cassin, Senior Environmental Health Officer ASPEN • PITKIN ENVIRONMENTAL HEALTH DEPARTMENT Date: April 4, 1995 Re: L'Auberge 1994 Tourist Accommodations GMQS, Code Amendment & Conditional Use Review Parcel ID # 2735-124-50-051 & -053 The Aspen/Pitkin Environmental Health Department has , reviewed the L'Auberge land use submittal under authority of the Municipal Code of the City of Aspen, and has -the following comments. SEWAGE TREATMENT AND COLLECTION: Section 11-1.7 'It shall be unlawful for the owner or occupant of -any building used for residence or business purposes within the city to construct or reconstruct an on -site sewage disposal device.' The plans to provide wastewater disposal for this project through the central collection lines of the Aspen Consolidated Sanitation District (ACSD) meet the requirements of this department. The ability of the Aspen Consolidated Sanitation District to handle the increased flow for the project should be determined by the ACSD. - The applicant must provide documentation that the applicant and the service agency are mutually bound to the proposal and that the service agency is capable of serving the development. ADEQUATE PROVISIONS FOR WATER NEEDS: Section 23-55 'All buildings, structures, facilities, parks, or the like within the city limits which use water shall be connected to the municipal water utility system., The provision of potable water from the City of Aspen system is consistent with Environmental Health policies ensuring the supply of safe -water. The City of. Aspen Water Department shall determine if adequate water is available for the project. The City of Aspen water supply meets all standards of the Colorado Department of Health for drinking water quality. A letter of service must be provided from the City of Aspen. Water Department documenting that the applicant and the service agency are mutually bound to the proposal and that the service agency is capable of serving the development. 1 130 SOUTH GALENA STREET asPEN, COLORADo 81611 • PHONE 303.920.5070 • FAx 303.920.5197 Printed on remled paper WATER QUALITY IMPACTS: Section 11-1.3 'For the purpose of maintaining and protecting its municipal water supply from Injury and pollution, the city shall exercise regulatory and supervisory jurisdiction within the Incorporated limits of the City of Aspen and over all streams and sources contributing to municipal water supplies for a distance of five (5) miles above the points from which municipal water supplies are diverted.' i This application is not expected to impact down stream water quality. AIR QUALITY: Sections 11-2.1 'ttis the purpose of [the air quality section of the Municipal Code] to achieve the maximum practical degree of air purity possible by requiring the use of all available practical methods and techniques to control, prevent and reduce air pollution throughout the city...' The land Use Regulations seek to 'lessen congestion• and 'avoid transportation demands that cannot be met' as well as to 'provide clean air by protecting the natural air sheds and reducing pollutants'. The. major concern of this department is the impact, of increasing traffic in a non - attainment . area designated by the EPA. To ensui e that traffic and PM,o levels do not increase more than specified in the State Implementation Plan for the Aspen area, and to be consistent with City policy any traffic generated by this development must be fully mitigated. In order to do this, the applicant will need to determine the traffic increases generated by the project, and the traffic decreased by each of the control measures. A condition of. approval should be that the applicant provide a mitigation plan that the Aspen/Pitkin 'Environmental Health Department determines is sufficient to offset any - increases in PM,, caused by the project_ FIREPLACE/WOODSTOVE PERMITS: The applicant must file a fireplace/woodstove permit with the Environmental Health Department before the building permit will be issued. Metropolitan areas of Pitkin County which includes this site may have two department certified devices and unlimited numbers of decorative gas fireplace appliances per building. New homes may NOT have wood burning fireplaces, nor may any heating device use coal as fuel. Barns and agricultural buildings may not install any type of fireplace device. CONFORMANCE WITH OTHER ENVIRONMENTAL HEALTH LAWS: NOISEABATEMENT: Section 16-1 'The it, council finds and declares that noise is a significant source of environmental pollution that represents a present and increasing threat to the public peace and to the health, safety and welfare of the residents of the City of Aspen and it its visitors ...... Accordingly, it is the policy of council to provide standards for permissible noise levels in various areas and manners and at various times and to prohibit noise in excess of those levels.' k During construction, noise can not exceed maximum permissible sound level standards, and construction cannot be done except between the hours of' 7 a.m. and 10 p.m-. on weekdays. It is very likely that noise generated during the construction phase of this project will have some negative impact on the neighborhood. The applicant should be aware of this and take measures to minimize the predicted high noise levels. ... V:WP:LAND USE:2735124500511AU 61 To: Leslie Lamont, Planning Office From: Chuck Roth, Engineering Department Date: April 10, 1995 Re: L'Auberge 1994 Tourist Accommodations GMQS, Code Amendment & Conditional Use Review (43 5 West Main Street, Lots 1 and 2, Perkins Subdivision - to be nullified and revert to Lots A -I, Block 38, Original Aspen Townsite) Having reviewed the above referenced application, the Engineering Department has the following comments: 1. Site Drainage - The application is not thorough concerning site drainage. If the project is approved, a storm runoff plan must be prepared by a registered engineer prior to issuance of a building permit. The plan must provide for no more than historic flows to leave the site. Percolation into landscaped areas of flows from 'newly constructed impermeable surfaces may suffice, but the percolation rates and flow quantities must be verified. 2. Sidewalk, Curb and Gutter - "Standard.- Facilitating and encouraging year hound pedestrian transportation. " - During the past summer, the City constructed sidewalk along the Main Street frontage of the property. It is of course unfortunate that City funds were used instead of the applicant providing the sidewalk as other private property owners must do. In spite of complaints from City staff and from the public, proper snow removal was not performed on the sidewalk. Snow was not removed from the sidewalk consistently throughout this past winter, and snow from the driveways was piled up on the sidewalk at both corners creating a hazardous pedestrian situation and discouraging pedestrian use. Sidewalk also needs to be constructed on the property frontages on 3rd and 4th Streets. This is required by City Code for new construction and 'is also identified by the "Pedestrian Walkway and Bikeway System" Plan. This should be a condition of approval for any development. The condition of the curb and gutter cannot be determined at this time due to snow. Any sections 1 needing replacement must be replaced prior to issuance of a certificate of occupancy. Curb and gutter must be constructed on the Third Street frontage. 3. Mass Transit - The existing bus stop is rudimentary. Perhaps an easement should be provided for a bus shelter and a bus shelter provided as a site improvement. 4. Community Character - The lodge currently has posted a sign in the public right-of-way at the corner of Fourth and Main which has not been removed despite staff requests. 5. Access & Driveways - City Code prohibits driveways onto Highway 82. The property contains existing, non -conforming driveways. The application represents a proposed increase in use of the existing driveways with more vehicles per day entering and exiting Highway 82 at the location. It is preferable to provide driveway access to the project from the alley. At a minimum, the applicant should be required to delete the Main Street curb cut to the manager's house. The new driveway off the alley will permit access to parking spaces 23 and 24. Access Widths - The accesses off Main Street are only drawn at 11.5' and 9.5' off the alley. The Fire Marshal should be specifically requested to approve those access widths, both at the curb and within the property. 6. Utilities - Any new surface utility needs for pedestals or other equipment must be installed on an easement provided by the applicant and not in the public right-of-way. The applicant must consult with the City Electric Superintendent prior to issuance of a building permit and provide electric load information in order to determine if a transformer easement is needed on the site. 7. Trash & Utility Area - The final development plans must indicate the trash storage area, which may not be in the public right-of-way. All trash storage areas should be indicated as trash and recycle areas. The applications states that the recycling is currently practiced, which is commendable. Any trash and recycle areas that include utility meters or other utility equipment must provide that the utility equipment not be blocked by trash and recycle containers. The current trash area is not indicated on the site improvement survey and appears to be within the alley public right-of-way. It should be a condition of approval that a concrete pad be provided for the dumpsters in order to facilitate their storage on private property. 8. Parking - The application requests a variance for parking space dimensions, but no specific dimensions are requested. The plans scale off to 8.7'xl4.8' for space #8, 8.2'x13.5' for space #9, 7.2' x 17' for space # 11, and 7.3' x 18' for space # 17. The proposed, scaled widths appear functional, however the length of space #9 is below the range of any but the shortest vehicles. It may be preferable to permit reductions in the number of parking spaces than to permit the undersizing of space #9. Prior to now, reductions- in parking space sizes have been addressed by special review and not by the variance process!. If the use of "grass-crete" is permitted, snow removal should be specifically required for maintaining the parking spaces in a usable condition. The "grass-crete" area, must include access 2 into spaces 911 and # 17. No access is currently shown to those spaces, and a parallel parking space is 22' long in order to permit the parallel parking turning movements. It is recommended that if "grass-crete" is permitted, board, stone, paver or concrete tire tread "rails" some 16" in width be required to clearly define the intended parking space and the access. This would permit considerable "greening" versus a completely paved or surface parking space and access. This is a detail that the Engineering Department would support verbally at the Planning & Zoning Commission meeting. 9. Site Design - The new cabins will be a major change to the Main Street corridor by filling in an existing open space. It might be preferable to retain the open space and provide development of increased height and below grade at the existing footprints. 10. Street Lights - The Neighborhood Advisory Committee is increasingly concerned about the lack of street lighting in town, especially in lodging areas. At a minimum, the applicant should be required to install an antique light on Third Street at the alley. A street light is needed at the other end of the same alley, which the applicant also abuts, but the property owners across the alley would potentially be responsible for that light. 11. Bicycles - The applications discusses bicycle storage but is not specific as to the number of bicycles for which storage is provided. Sufficient storage for all bicycles of guests, visitors and employees should be provided. 12. Other Improvements, - The applicant is not offering to pave the alley. Paving alleys is a current trend because of dust and mud reduction for adjacent properties. There is also a PM-10 benefit. 13. Other Conditions of Approval - a. No tracking of mud onto City streets shall be permitted during construction. b. The applicant shall agree to join any improvement districts formed for the purpose of constructing improvements in adjacent public rights -of -way. c. It is suggested that the applicant provide 2 sets of mylars, one for recording together with fees, of the approved development plan together with the existing conditions survey. For the applicant's protection, as well as any possible grantees, the survey should state that all easements of record as indicated on Title Policy No. , dated , have been shown on the survey. 14. Work in the,Public Right-of-way - Given the continuous problems of unapproved work and development )in public rights -of -way adjacent to private property, we advise the applicant as follows: The applicant shall consult city engineering (920-5088) for design considerations of 3 development within public rights -of -way, parks department (920-5120) for vegetation species, and shall obtain permits for any work or development, including landscaping, within public rights -of -way from city streets department (920-5130). 15. Code Amendment - There do not appear to be any adverse impacts of engineering concern for amending the Code to include "lodges" as a conditional use in the Main Street Office Zone District. There are sufficient utilities available to serve the proposed project. The impacts on services of a lodge are the same as "bed and breakfast" businesses. 16. Encroachment Application - Encroachment applications relate to public property and public rights -of -way and are granted by the City Engineer. Encroachment licenses must be applied for through that office. An application has been mailed to the applicant's representative. Encroachments are generally required to be removed at the time of redevelopment. This will be examined in depth at the time that an encroachment application is received. The application does not make reference to the fences that encroach into the Forth Street and alley rights -of -way. These fences may be included in the encroachment application, however it is likely that the fences will be required to be relocated onto private property at the time of any development or any future building permits for any work. 17. Vacation of Final Subdivision Plat - Since the word "vacation" applies to vacating public rights -of -way, the word "nullification" might avoid confusion. The Engineering Department has no objections to nullifying or voiding the subdivision plat of the Perkins Subdivision. cc: Cris Caruso, City Engineer Dave Gibson Gideon Kauftnan M95.61 4 MEMORANDUM TO: Leslie Lamont, Planning Office FROM: Cindy Christensen, Housing Office DATE: April 10, 1995 RE: L'Auberge 1994 Tourist Accommodations GMQS, Code Amendment & Conditional Use Review Parcel ID No. 2735-124-50-051 & -053 ISSUE: The applicant is proposing to - add 12 guest cabins, a laundry/employee locker area, and a bathroom addition to the -� manager's residence, for a total of 4,534 gross square feet of new construction. The applicant presently has a two -bedroom manager's unit located within the residence. They are proposing that this remain in free-market ownership with a binding Housing Authority deed restriction which requires that mitigation be paid, if and at such time as the dwelling may be sold. The applicant is proposing a cash -in -lieu fee of $108,330 (1.57 X $69,000) for the additional employees. The cash -in -lieu fee is presently in the process of being increased with the adoption of the 1995 Aspen/Pitkin County Housing Guidelines. This could go into effect as early as mid May, which would require the cash -in -lieu payment of $124,030. POINTS: Appendix 3 does seem in line with the FTE's required, which represents that the proposed development would increase FTE's by .68 (1.83 - 1.15). The applicant is proposing a cash -in -lieu payment for 1.57 low income employees, which represents ya 1000 housing mitigation. This results in a score in this category!\of 11 points. = The Housing Board has established priorities in the Affordable Housing Guidelines regarding mitigating affordable housing impacts. The priorities are as follows: 1. On -site housing; 2. Off -site housing, including buydown concept; 3. Cash-in-lieu/land-in-lieu. The Housing Office recommends that the housing mitigation be met on -site. MANAGER'S UNIT: The applicant is requesting that the manager's unit remain in free-market ownership with a binding Housing Authority deed restriction which requests that mitigation be paid, if and at such time as the dwelling may be sold. The Housing Office recommends deed restricting this manager's unit to Resident Occupied, which limits the unit to occupancy by qualified employees, but not as to price or income limitations. This would also restrict the use and occupancy of the unit to residents and their families who are either employed by the owner or who are residents of Pitkin County and fall within the Housing Authority qualification guidelines established and indexed by the Authority on an annual basis. If approved as requested and prior to building permit approval, the Housing Office will require the net liveable square footage calculation for the unit, a copy of the floor plans of this unit, and a recorded deed restriction. The Deed Restriction should be obtained from the Housing Office. \word\referral\lauberg.gmq 2 EXHIBIT B EXHIBIT B Conditional Use Review - Pursuant to Section 24-7-304 the criteria for a conditional use review are as follows: A. The conditional use is consistent with the purposes, goals, objectives and standards of the Aspen Area Community Plan, and with the intent of the Zone District in which it is proposed to be located; RESPONSE: There are several small lodges on Main Street. Nine of those are zoned Lodge Preservation, but L'Auberge is not. For several reasons, the applicants sought a text amendment to allow lodges as a conditional use in the Office zone rather than rezone their property to LP. In the Commerical/Retail Action Plan section of the Aspen Area Community Plan states that: small lodges immediately set the stage for the guest experience in Aspen. The community must find ways to maintain these small lodges and the experience they offer to our guests. L'Auberge is currently a non -conforming use in the office zone. The approved text amendment enabling small lodges as a conditional use and a supportive conditional use approval will enable L'Auberge to expand but remain an important element on Main Street. B. The conditional use is consistent and compatible with the character of the immediate vicinity of the parcel proposed for development and surrounding land uses, or enhances the mixture of complimentary uses and activities in the immediate vicinity of the parcel proposed for development; RESPONSE: Main Street is identified as a Historical District. The variety of uses along Main Street, which include the small lodges, is believed by the Historic Preservation Committee to enhance the streetscape of Main Street and helps to preserve the historical fabric of the street. The office zone district includes many incentives for the reuse and adaptation of historic structures in the zone. Although L'Auberge is not eligible for Landmark status, the HPC regards the small cottages as an important historical element for Main Street and have been very supportive of their expansion. The continued existence and the expansion of L'Auberge is compatible with the surrounding uses on the street. C. The location, size, design and operating characteristics of the proposed conditional use minimizes adverse effects, - = including visual impacts, impacts on pedestrian and vehicular 1 circulation, parking, trash, service delivery, noise, vibrations and odor on surrounding properties; RESPONSE: The applicants have submitted a landscape plan that indicates an of one the three curb cuts on the street. A revised site -plan was also submitted. It appears from the revised plans that some of the parking spaces have been reconfigured. However, placement of the parking space directly in front of the office, perpendicular to Main Street is inappropriate. One of staff's original criticism of this site plan is the auto domination on the site. Completely blocking the front of the office with a parking space, even though it is grass-crete exacerbates the auto intensity of the site. The parking requirement for lodges is .7 spaces per bedroom. Currently there appear to be twenty-one parking spaces for 20 cabins, an office, and a manager's residence. If the parking were reduced to .7 per lodge unit only 14 spaces would be required. It is staff's opinion that on -site parking may be reduced. Staff recommends that the applicant continue to revise the parking plan. D. There are adequate public facilities and services to serve the conditional use including but not limited to roads, potable water, sewer, solid waste, parks, police, fire protection, emergency medical services, hospital and medical services, drainage systems, and schools; RESPONSE: The applicant continues to work with the service/utility agencies. A revised utility plan shall be submitted for review and approval prior to the allocation of GMQS allotments by City Council. E. The applicant commits to supply affordable housing to meet the incremental need for increased employees generated by the conditional use; and RESPONSE: In the GMQS application the applicant proposed to mitigate employee generation via cash -in -lieu. Staff recommended the provision of housing on -site. The applicant was successfully scored for a lodge allocation by the Joint GMQS Commission without on -site affordable housing. City Council will ultimately accept the form of housing mitigation. F. The proposed conditional use complies with all additional standards imposed on it by the Aspen Area Comprehensive Plan and by all other applicable requirements of this chapter. RESPONSE: Conditional use approval with the conditions outlined in the memo, and adhering to the representations made at the joint GMQS Commission meeting, will enable the applicant to comply with all the standards of the Land Use Code. 0 TO: MEMORANDUM Planning and Zoning Commission Kim Johnson, Planner DATE: May 9, 1995 Re: Water Place Affordable Housing Subdivision - Final SPA Development Plan and Amendment of the Aspen Water Plant SPA, Growth Management Exemption for Affordable Housing and Essential Public Facilities, Subdivision, 8040 Greenline Review, Conditional Use, and Special Review for Parking, Open Space, and Dimensional Requirements in the Public Zone District: Public Hearing Continued from May 2, 1995 This item was introduced at a public hearing on May 2. At that meeting, the Commission voted to require this project to be processed as a four step SPA review rather than the requested two step consolidated review. The result of this action means that the application will be reviewed as a . Conceptual SPA Plan. Presentations were made by staff, the applicant and several citizens. Issues discussed regarded roadway design and safety, open space and park site, visual impacts of new homes, density of the project, chlorine storage, and deed restrictions of the units. Staff has no new information to present to the Commission. The Commission shall forward their recommendation to the City Council. Currently, the Council review date is set for May 22, 1995. Threshold issues and concerns will be stated as conditions of Conceptual review. The applicant will then submit a Final SPA application which responds to the Conceptual conditions. The Commission and Council will hold additional public hearings for Final SPA review. ** Please be sure to bring your staff memo and application materials distributed prior to the last meeting.
