PUBLIC HEARING (cont'd) A. Residential Zone District Regulations Note: Please remember to bring in your Code notebooks so that we can replace Articles 1 through 6. A. COV MEMORANDUM TO: Aspen Planning and Zoning Commission FROM: Alan Richman, Planning and Development Director RE: Revisions to Residential Zone District Requirements DATE: October 23, 1987 Attached is a revised version of Exhibit 1, based on the comments received from you at the meeting on October 20. As of the time of drafting of this memo, I have not yet met with the committee of architects and other interested citizens. I have revised the proposal which was made last week, without deviating from the basic approach of combining setback changes with a site coverage limitation. Further revisions will be made if you decide to accept the "progressive setback" approach of the committee, rather than the site coverage approach of the staff. Following is a section -by -section description of the changes I have made, with analysis as required. Section 1 #4: Language added allowing garage at 5 feet from rear lot line. #5: Side yard total size limitation changed into a continuous scale, slight reduction in requirement for all lots in excess of 3,000 sq. ft. #6: Maximum site coverage limitation changed into a continuous scale, elimination of requirement for 3,000 sq. ft. lots, slight increase in allowable coverage for all other lots. The attached Table 1 demonstrates the relationships between the proposed FAR, setbacks and site coverage. The table demonstrates that setbacks alone will not be able to limit houses from covering the vast majority of the lot. Furthermore, on the larger lots, two and greater story volumes can be created, while still maximizing allowable FAR. I am unable to comment on how the committee's approach will address this problem, but can conclusively state that applying only the setbacks proposed in Section 1 will not resolve the problem. Therefore, I continue to recommend a site coverage requirement. The values I am recommending will allow from about 64 to 72% of maximum allowable FAR to be built on the first story. This means that in a two story house, there should be adequate room to build out to the maximum house size allowed by the Code, plus garage, without permitting too much latitude for the creation of the two story spaces. I continue to believe that the volume calculation methodology proposed in Section 4 of Exhibit 1 will also help to resolve this problem. Section 2 There are no changes from last week's proposal. Section 3 This section retains the current FAR's in the RMF, R-15, R-15A, R-30 and R-40 zone districts. This section is needed because of the way FAR's are now codified in Section 24-3.4 of the Code. Please note that those sections of prior Exhibit 1 is recomm- ended revisions to the setbacks and FAR in these zones have been deleted at your direction. Sections 4,5 and 6 There are two changes in Section 4 and none in Section 5 or 6. One change is in response to your direction to increase the garage exemption from 400 to 500 square feet. Another area which will require your attention is subsection (2), decks, balconies and stairways. I need direction on how to handle at grade decks, stairways and terraces which are covered. There has been considerable debate between architects and staff as to whether or not to count such areas toward the 15% of the floor area which is excluded. I can see both sides of this issue (although for the sake of argument, the draft states that such areas do not count),but look for it to be resolved by you and Council. I cannot stress too strongly the importance of adopting these clarifications and substantive revisions to existing sections of the Code. The new calculation methodology will help to marg- inally reduce the size of buildings which can be built, as well as be a much simpler methodology to use. The nonconforming provisions will be a benefit to owners of existing structures which cannot meet the new Code provisions, by removing the cost limitation on repairs and maintenance and by being clear and consistent. The rules also benefit the community at large by not grandfathering all nonconformities, but instead requiring compliance with the Code, whenever investment of greater than 500 of the fair market value of the structure is made, or whenever a structure is willfully destroyed. RECOMMENDATION: The Planning Office recommends that you direct us to draft a resolution which includes all of the proposals con- tained in Exhibit 1, and that you schedule a special meeting later this week to adopt that resolution. ex.1cover 7.. co Co M O 0) Co � z II o0 O II 0o o Ilzr 11 co II 00 II 00 II 0o N CoN HN H to l0l0 H co loO to v4 t-CO to Q t-N H NM NM Nd' NM NI "It 4� 4-1 co O CO Iry M In Q L II II � H H 0 0 0 11 0 0 II 0 0 II 0 0 II 0 0 it 0 0 O O N O d' 0 l0 O Co O d' O l0 d' H CO co N N l0 N O Q Co to N (V N N M ICZi' M d' mot' LO M LO d+ lfl lfl � � lQ l4 lfl lfl � � II II C)l C) II II II010 010 co 00 ON d' � LO Co O O lfl 0 �-I Nd' Nlo d'0) LON O O O O 0 co N � ci N Ny' ®O� O NO1 MOyi O O ® O O r I O LO O O O p M d' lfl 0) N IDOAVIRO�- W - - Wroyewl That in the R-6 zone district, the minimum front yard, side yard and rear yard setbacks, as established in Section 24-3.4 of the Municipal Code, be repealed and be re-enacted to read as follows: 4.

In measuring floor areas for floor area ratio and allowable floor area, the following applies: 1) General. In measuring floor area for the purposes of calculating floor area ratio and allowable floor area, there shall be included that floor area within the sur- rounding exterior walls (measured from their exterior surface) of a building, or portion thereof. (2) Decks, balconies and stairways. The calculation o floor area of a building, or a portion thereof, shal exclude decks! stairways, balconies, porches, terrace and similar features when the total area of suc features is: I (a) Not surrounded by exterior walls or enclosed, provided the area may be covered by a projection from the building which is less than or equal to three (3) feet, and further provided that a porch may be covered by a roof or projection from the building of unlimited size; and (b) Above natural grade; anon (c) Less than or equal to fifteen percent (15%) of the maximum allowable floor area of the building. All area included in a deck, stairway, balcony, porch, terrace or similar feature which does not meet all of the above conditions shall be included as part of the floor area calculation, provided that all area included in a deck, stairway, balcony, porch, terrace or similar feature which is at or below natural grade shall be entirely excluded from floor area calculations. (3) Garages and carports. For the purpose of calculatinif floor area ratio and allowable floor� area for building or portion thereof whose principal use i residential, garages and carports shall be excluded u 41 W, to a maximum area of five hundred (500) square feet per dwelling unit; all garage or carport space in excess of five hundred (500) square feet per dwelling unit shall be included as part of the residential floor area calculation. For any dwelling unit which can be accessed from an alley or from a private road entering at the rear of the dwelling unit, the garage shall only be excluded from floor area calculations if it is located on the alley or at the rear of the unit. (4) Subgrade areas. The area of any story which is one hundred (100%) percent subgrade, as measured from natural grade, shall be excluded from floor area calculations. For any story which is partly above and partly below natural grade, a calculation of the total volume of the story which is above and which is below grade shall be made, for the purposes 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 wall area of the story which is above natural grade 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 calcula- tion. (5) Volume. For the purpose of calculating floor area ratio and allowable floor area for a building or portion thereof whose principal use is residential, a determin- ation shall be made as to those areas within the building which are less than ten (10) feet in height and those which exceed ten (10) feet in height, as measured from floor to ceiling. Those areas which are ten (10) feet or less from floor to ceiling shall count toward allowable floor area at the ratio of one (1) square foot for each one (1) square foot of floor area. For those areas which exceed ten (10) feet from floor to ceiling, the ratio at which they shall count shall increase by five one -hundredths (0.05) of a square foot for each one (1) foot increase in height, to a maximum ratio of two (2) square feet for each one (1) square foot of floor area. (6) Planned Unit Development. For detached residential and duplex Planned Unit Development applications, the allowable floor area shall be calculated by determining the square footage of the entire land ownership, reduced according to the provisions of Section 7- 903(B)(2)(b). The reduced square footage or land shall then be divided by the total number of dwelling units existing and proposed for development to determine the land area for each detached residential unit or duplex in the Planned Unit Development (PUD) , which shall b the area used to determine the amount of floor are each detached residential unit or duplex in the Planne Unit Development (PUD). The total floor area allowe* for the Planned Unit Development (PUD) shall be th, cumulative total of the floor areas for each detachele 0 residential units and duplexes in the Planned Uni Development (PUD). That Article XIII of Chapter 24 of the Municipal code be repealed and re-enacted to read as follows: Sec. 24-13.1. PuLr'pose. Within the Zone Districts established by this chapter, there exist uses of land, buildings and structures that were lawfully established before this chapter was adopted or amended which would be in violation of the terms and requirements of this chapter. The purpose of this article is to regulate and limit the continued existence of these uses, buildings, and structures that do not conform to the provisions of this chapter or any amendments thereto. It is the intent of this article to permit these nonconfor- mities to continue, but not to encourage their survival. it is further the intent of this article that nonconformities should not be enlarged or expanded. The provisions of this article are designed to curtail substantial investment in nonconformes and to bring about their eventual elimination in order to preserve the integrity of the Zone Districts and the other provisions of this chapter. Sec. 24-13.2. Nonconforming uses. A. Authority to continue. Nonconforming uses of land or structures may continue in accordance with the provi- sions of this article and this section. Normal repair and maintenance. Normal maintenance and repair to permit continuation of nonconforming uses may be performed in any period of twelve (12) consecu- tive months, to an extent not exceeding ten (10%) percent of the current replacement cost of the struc- ture. C. Extensions. Nonconforming uses shall not be extende This prohibon shall be construed so as to prevent:1 Enlargement of nonconforming uses by addons t# VA the area of the structure in which such noncon- forming uses are located; or 2. Occupancy of additional lands. D. Relocation. A structure housing a nonconforming use may not be moved either to another location on or off the parcel of land on which it is located, unless the use thereafter shall conform to the limitations of the Zone District into which it is moved. E. Change in use. A nonconforming use shall not be changed to any other use unless the new use conforms to the provisions of the Zone District in which it is located. F. Termination. 1. Abandonment or discontinuance. The intent of the owner notwithstanding, where a nonconforming use of land or structure is discontinued or abandoned for twelve (12) consecutive months, then such use may not be re-established or resumed, and any subsequent use must conform to the provisions of this chapter. 2. Damage or destruction. Any structure housing a nonconforming use which is damaged or destroyed to the extent of less than fifty (50%) percent of the fair market value of said structure or which is damaged or destroyed to any extent by an act of God or through any manner not willfully accomp- lished by the.owner may be restored as of right if a building permit for reconstruction shall be issued within twelve (12) months of the date of damage. Any structure housing a non -conforming use which is willfully damaged or destroyed to the extent of more than fifty (50%) percent of the fair market value of said structure shall only be restored in conformance with the provisions of this chapter. Sec. 24-13.3. Nonconforming structures. A. Authority to continue. A nonconforming structure devoted to a use permitted in the Zone District in which it is located may be continued in accordance with the provisions of this article. 8 F&O Normal repair and maintenance. Normal maintenance and repair of nonconforming structures may • - performed any period ofconsecutive months limit on cost of - maintenance . • repair. C. Extensions. 1. General.

Structure in stream margin. Any part of a nonconforming structure which is in the stream margin as established pursuant to Sec. 7-504, which is damaged or destroyed to the extent of less than fifty (50%) percent of the fair market value of the structure, may be restored as of right if the structure can be rebuilt in the original footprint, consistent with the provisions of Art. 7, Div. 5. C. Unsafe structure. Any portion of a noncon- forming structure which becomes physically unsafe or unlawful due to lack of repairs and maintenance, and which is declared unsafe or unlawful by a duly authorized City official, shall only be restored,, repaired or rebuilt in conformity with the provisions of this chapter. Sec. 24-13.4. Nonconforming accessory uses and accessory structures. No nonconforming accessory use or accessory structure shall continue after the principal structure or use shall have ter- minated unless such structure or use thereafter shall conform to the provisions of the Zone District in which it is located. Sec. 24-13.5. Lodge and hotel preservation. All lodge and hotel uses and structures that are lawfully established at the time of adoption of this chapter or an amendment which would be considered to make the lodge or hotel a nonconforming use or structure under this chapter are hereby declared to be conforming and not subject to the provisions of this article as long as the following standards and requirements are met. A. Reconstruction or renovation. All reconstruction of a structure shall meet the dimensional requirements of the underlying Zone District. Renovation shall not increase the nonconformity of the structure. Renova- tion is the investment of up to fifty (50%) percent of the appraised value of the structure, net of land value. Reconstruction is the investment of fifty (50%) percent or more of the value of the structure, net of land. 10 Felt. Increase in units or sThere shall be no increase in the number of units in the lodge or hotel, or the total square footage in the lodge or hotel, unless the enlargement is for the purpose of constructing deed restricted employee housing units accessory to the principal use. C. Construction of employee housing. The enlargement of the lodge or hotel for the purpose of constructing employee housing shall be reviewed and considered as a Development Application for a conditional use pursuant to Art. 7. Div. 3. In determining whether to approve, approve with conditions, or disapprove the application, the Commission shall ensure the following standards and requirements are met. 1. There is no increase in lodge or hotel units; 2. The proposed employee housing units are in compliance with the adopted housing plan, and specifically the need for seasonal employee rooms; 3. There is a maximization of construction quality and unit size in the proposed employee housing units; 4. There are adequate public facilities to serve the proposed development, and off-street parking is provided pursuant to Art. 5, Div. 3. 5. The proposed employee housing is compatible with surrounding land uses and the dimensional require- ments of the underlying Zone District. 6. The proposed employee housing is deed restricted to the employee rental guidelines, and against commercial rental or sale. In the event the lodge is condominiumized, the deed restricted units must be retained as a portion of the common elements of the lodge or hotel. 7. The proposed employee housing receives health, safety and fire inspection and commitments are made to comply with the results of said inspec- tion. 8. The deed restricted employee housing units are limited in their rental solely to employees of the lodge or hotel, and shall not be rented to other employees of the City nor rented on the open M market. 9. The expansion may be in rental rooms, provided an equal amount of existing square footage of space is converted from rental rooms to deed restricted employee housing units. D. Abandonment. The intent of the owner notwithstanding, when a lodge or hotel subject to this section is discontinued or abandoned for twelve (12) consecutive months, then the use may not be re-established or the structure occupied, without conforming to the standards and requirements of the underlying Zone District. E. Damage or destruction. If a lodge or hotel subject to this section is damaged or destroyed by any means and is not repaired or replaced within two (2) years from the date of damage or destruction, it shall be recon- structed pursuant to the standards and requirements of this chapter. Sec. 24-13.6. Nonconforming lots of record. A. General. A detached single family dwelling and customary accessory buildings may be developed on a lot of record if: 1. The lot of record is in separate ownership and not contiguous to lots in the same ownership; and 2. The proposed single family dwelling can be located on the lot so that the yard, height, open space and floor area dimensional requirements of the Zone District can be met, or a variance is obtained to vary from said dimensional require- ments pursuant to Article 10. B. Undivided lot. If two (2) or more lots or combinations of lots with continuous frontage in single ownership (including husband and wife as in all cases a single owner) are of record at the effective date of the adoption or amendment of this chapter, regardless of time of acquisition, and if all or parts of the lots do not meet the requirements established for lot width and area, the lots shall be considered an undivided parcel, and no portion shall be used or occupied which does meet the width and area requirements of this chapter. Sec. 24-13.7. Lot reduction. A. No lot or interest therein shall be transferred, conveyed, sold or subdivided so as to create a new W-1 nonconforming lot, to avoid, circumvent or subvert any provision of this chapter, or to leave remaining any lot in violation of the dimensional requirements of this chapter. B. No lot or portion of a lot required as a building site under this chapter shall be used as a portion of a lot required as a site for another structure. C. No building permit shall be issued for any lot or parcel of land which has been conveyed, sold, or subdivided in violation of this section. Any trans- feree who acquires a lot in violation of this paragraph without knowledge of such violation, and any subsequent transferee, shall have the right to rescind and/or receive damages from any transferor who violates the provisions of this paragraph. That the following definitions be added to Section 24-3.1 of the Municipal Code: NONCONFORMING STRUCTURE means any structure which was estab- lished pursuant to the zoning and building laws in effect at the time of its development, but which no longer conforms to the dimensional requirements imposed by this Code for the Zone District in which it is located. NONCONFORMING USE means any use of land, building or structure, which was established pursuant to the zoning and building laws in effect at the time of its development, but which use is no longer a permitted or conditional use under the regulations imposed by this Code for the Zone District in which it is located. NORMAL MAINTENANCE AND REPAIR OF A NON -CONFORMITY means any work done in a period of twelve (12) consecutive months on ordinary repairs, or on repair or replacement of non -bearing walls, fixtures, wiring or plumbing. SITE COVERAGE means the percentage of a site covered by build- ings, excluding roof or balcony overhangs, measured at the exterior walls or supporting members of a building at ground level. "K
