ADJOURN MEETING s s x MEMORANDUM TO: Aspen Planning and Zoning Commission FROM:, Cindy Houben, Planning Office RE: Lee Stream Margin Review DATE: July 5, 1988 REQUEST: Approval of a Stream Margin Review to enlarge an. existing deck and add a lower deck adjacent to the river. APPLICANT: Harlan Lee. LOCATION: Lot 12 Calderwood Subdivision, 1106 Waters Ave. HISTORY: The Planning Commission has approved two other stream margin reviews for this parcel. The most recent review was in October of 1987 for additions to an existing house. Prior to that review, the applicants were granted stream margin review approval in 1978 for additions to the original house. The following were conditions of approval for the 1987 review: 1) Revised foundation and site coverage plans shall be prepared which continue to leave the steep slope of the river bank undisturbed and eliminate the need to remove more than the four cottonwood trees identified. 2) The applicant shall replant, or replace with new trees the four cottonwood trees prior to occupancy of the addition. A revised site plan showing relocation of three cottonwood trees, specifying the caliper at a minimum of 2 1/2" - 311, and planting one blue spruce a minimum of 8' tall shall be submitted to the satisfaction of the Planning Office priori to issuance of a Building Permit. 3) The lower deck shall either be removed or anchored for the purpose of not breaking loose in case of a flood. Design of the anchoring shall be approved by a professional engineer and it shall be installed prior to occupancy of the addition. 4) Excavation and construction techniques shall be specified in the Building Permit application to ensure to the satisfaction of the Building Department, that no undue disturbance of the stream bank or to the Roaring Fork River will result. s The applicants are now in the process of putting on the additions which were approved in 1987 and are in the process of satisfying the conditions as listed above. During this review process the applicants requested that we review condition number 2 above. The size of the -required trees have a larger root base than can be placed next to the house. In addition, the approved location of the 8spruce tree is situated on a steep slope down to the river. In order to place the tree in the approved location the bank would have to be disturbed and revegetated. The Planning Office has determined that due to site constraints the applicants may substitute 5 smaller cottonwoods for the 3 larger cottonwoods to be placed along the side of the house. The Planning Office has also determined that it is more appropriate to locate 3 smaller spruce trees on the slope rather than the one 8' tree. The smaller trees can be hand carried and planted thereby causing less damage to the bank. DESCRIPTION OF THE PROPOSAL: The applicants are proposing to construct a 610 square foot deck on the back side of their house along the Roaring Fork River. This deck is above. the 100 year flood boundary. The applicants are also proposing to reconstruct a deck which is adjacent to the river along the 100 year flood boundary line. REFERRAL COMMENTS: 1) Engineering Department: Jim Gibbard of the Engineering Department notes the following concerns in his attached memorandums: a. The high water line needs to be drawn and labeled. b. The proposed addition to the deck needs to be shown more clearly on the plat. r C. The four caisson foundations proposed for the support of the deck should be placed so they will not damage the root systems of the trees that currently penetrate the existing deck. d. The design of the anchor of the deck at the river shall be approved by a professional engineer. STAFF COMMENTS: Section 24-6.3(e) of the old Code requires that the application for stream margin review respond to the following criteria: 1) Criteria: No development shall occur within a special flood hazard area unless it can be demonstrated that there will be no increase in base flood elevation as a result of the development, as shown by an elevation certificate prepared 2 r relocated, the applicant and applicant's heirs, successors and assigns shall provide maintenance to assure that the floor carrying capacity is not diminished. Criteria: Copies shall be submitted of all necessary federal and state permits relating to work within the one hundred year floodplain. Response: No federal permits are required for this proposal and no alteration of the stream will occur as a result of this proposal. RECOMMENDATION: The Planning Office recommends approval of the Stream Margin Review for the Lee parcel with the following conditions: 1) All representations of the applicant shall be considered conditions of approval. 2) Prior to the issuance of a building permit for the deck, the applicants shall plant 5 cottonwoods along the east side of the house. In addition, 3 spruces shall be planted on the slope between the house and the river. 3) The following shall be supplied to the Engineering Department and Planning Office prior to issuance of a building permit for the deck: a. The high water line shall be placed on the plat. b. The proposed deck needs to be shown clearly on the plat. c. Written confirmation from a landscape canape that the ---� four caisson foundations proposed for the support of the deck will be placed so they will not damage the root systems of the trees that currently penetrate the existing deck. d. The design of the anchoring of the new deck at the river shall be approved by a professional engineer. CH.LEESMR 4 MEMORANDUM TO: Aspen Planning and Zoning Commission FROM: Cindy Houben, Planning Office RE: CBS Preliminary Subdivision/Public Hearing DATE: July 5, 1988 APPLICANT: Fifty Seven, Inc. REQUEST: Approval of a preliminary subdivision review for the resubdivision of lots 10-16 Block 28. ZONING: Office (0). DESCRIPTION OF THE REQUEST: This application is made pursuant to Section 20-19.of the old Aspen Municipal Code. The request is to except the development from the conceptual subdivision review stage since such review serves no public benefit and no major issues are involved in this request. (The new Code allows an application of this nature to go through a 2 step process submitting only final plans to both the Planning Commission and the City Council). The Planning Office agrees with this approach. Therefore, the application before you is the preliminary review of the CBS subdivision. The City Council will review the final plat. The applicants are proposing to demolish the existing residential units on site (the exact number of existing units is being verified by the Zoning Official at this time. The Planning Office feels confident that there are at least 6 units which may be used as replacement units for this proposal). The application is to resubdivide the existing 2 lots into 3, 6000+ square feet lots. and build 3 duplex townhome structures (see attached maps for existing conditions and proposed site plan). The development data for the.proposal is as follows: 1. Existing Zoning Office (0) 2. Total site area(there are two existing parcels) parcel 1 6000 sq. ft. parcel 2 15000 sq. ft. Total 21000 sq. ft. Y 3. Min. required lot size 6000 sq. ft. 4. Min. required lot area/ 6000 sq. ft. duplex unit 5. Proposed lot area lot 1 6,600 sq. ft. lot 2 7,800 sq. ft. lot 3 6,600 sq. ft. 6. Open Space requirement none 7. Proposed open space lot 1 4,150 sq. ft./ 63% lot 2 4,950 sq. ft./ 63 % lot 3 4,100 sq. ft./ 62% 8. Proposed # of Bedrooms 18 (6 three bedroom units) 9. Proposed Parking spaces 24 (18 required) The townhouse units are proposed to be similar in design and will each contain approximately 2,500 - 3,000 sq. ft. The parking is proposed to access off the existing alley. Two spaces for each unit will be provided in covered garages and two spaces will be provided on the paved aprons of the two car garages. Thus four parking spaces are provided per unit. Sidewalks will be built along the property lines on Spring and Hopkins Street pursuant to the regulations of the Code. Curb and gutter will be replaced along those streets where necessary. A handicap access ramp will be provided at the corner. of Spring and Hopkins. Two dumpsters will be provided in two enclosed trash areas adjacent to the alley at the rear of the site. As noted in the above chart, no open space is required . The applicants are, however, providing approximately 62-63% of open space on each of the lots. The proposal includes landscaping and partial fencing of the parcels. The applicant states that this fence will be a low fence perhaps of a rod iron type. The Parks Department has inspected the property and determined that several of the large cottonwoods on the site are diseased. The applicants propose to remove these prior to construction (see attached site plan). REFERRAL COMMENTS: 1. Fire Marshal: Wayne Vandemark notes that the property is within a three minute response time and can adequately be 2 served in the event of a fire. 2. Engineering: Elyse Elliott of the Engineering Department made the following comments in a memorandum dated May 12, 1988: * Utilities are in place to serve the proposed project. * The applicants must submit drainage plans which retain the historic flow rates on the property and the Engineering Department must approve any drywell design. * The applicants must submit a plat in accordance with the requirements of the Aspen Municipal Code. * The covered garage parking spaces must be of a size in accordance with the Code requirements. * Sidewalks and all right-of-way areas must conform to the streetscape guidelines and all pertinent regulations of the Engineering Department. * During construction, the applicants must coordinate with the Engineering Department with regard to any disruption to pedestrian and vehicle circulation. * Paving of the alley is not required, however, is recommended by the Engineering Department. 3. Aspen Water Department: In a memorandum dated May 18, 1988, Jim Markalunas notes that there is adequate water to serve the development. He also states that the service lines -must be inspected in order to determine whether or not they need to be replaced. 4. Aspen Consolidated Sanitation District: In a memorandum from Heiko Kuhn, he notes that there are several breaks in the line serving this property which must be repaired by the applicant prior to service by the ACSD. PLANNING STAFF COMMENTS: 1. The proposal conforms to the zone district requirements of the O zone with regard to area, bulk and uses. The proposed lot sizes are generally consistent with the surrounding area. 2. Section 7-1004 of the Code states the review standards for a subdivision. These are as follows : CRITERIA: 3 a. The proposed subdivision shall be consistent with the Aspen Area Comprehensive Plan. RESPONSE: The proposal is located in the central area as designated on the 1973 Aspen Area Comprehensive Plan. The following is taken from the plan: Central Area: To allow the primary use of land for tourist commercial activity that is essential to the community's economic vitality in an area that relates well to the proposed public transportation system, the ski areas and existing tourist oriented businesses. Ordered yet diversified land uses, such as resident related commercial, residential and professional office uses, should be located on the fringe of the central area. Urban design consideration is an essential element of future development or redevelopment of the central area and is necessary to take advantage of the unusual opportunities presented by its historic heritage and the relationship of the central area and Aspen Mountain.. This design element includes as primary concerns the preservation of historic sites, structures and mountain views, implementation of tree planting programs, as well as expansion of the pedestrian oriented mall area. The Plan does not preclude this type of residential development, however, it does note that it should be resident related. The Planning staff questions the affordability of the proposed structures for the residents of Aspen, but recognizes that there are no regulations implementing this policy of the 1973 Plan. CRITERIA: b. The proposed subdivision shall be consistent with the character of the existing land uses in the area. RESPONSE: The existing uses in the area are primarily single family, duplex and multi family structures. The proposed duplex use is consistent with these uses. CRITERIA: C. The proposed subdivision shall not adversely affect the future development of surrounding areas. RESPONSE: The proposal will further encourage the re- development of the east end of town as a second home (townhome) market. Historically this area has been a mixed neighborhood containing local residences as well as condominiumized second home and short term accommodations. While this type of development may not be a desirable one for the community, there are no regulations prohibiting it 4 from occurring. Please be aware that we are currently looking at writing displacement regulations which would address this problem. CRITERIA: d. The proposed subdivision shall be in compliance with all applicable requirements of this chapter. RESPONSE: The application is in conformance with the requirements of this chapter with regard to use, bulk and services. The Planning Office would like to remind the Commission that in 1987 we recommended that single-family and duplex residences in the 0 zone be subject to the sliding scale and not be eligible for the 0.75:1 FAR of the district. You did not support this recommendation. Based on the current development fever on the east side of town, we suggest you think about directing us to pursue the 0 and C-1 zones with regard to the sliding scale. 3. Section 20-9 of the old Code and Section 7-1004 of the existing Code refer to the suitability of land for subdivision. a. Land Suitability - The proposal is not located on land which has environmental concerns with regard to mud flow, flooding or other natural hazards. b. Spatial Pattern Efficient - The proposal is not located on land which will cause inefficiency with regard to duplication or premature extensions of utilities and unnecessary public costs. 4. Section 20-16 of the old Code and Section 7-1004(3) of the new Code refer to Improvements which are required by the developer. The Engineering Department has reviewed these in their comments listed above. These improvements are required by ,the Code for new subdivisions and must be provided by the applicants to the approval of the Engineering Department. Most of these details have not yet been provided by the applicant and are required to be adequately addressed at final plat. RECOMMENDATION: The Planning office recommends that the Planning Commission recommend approval of the CBS Subdivision Preliminary Submittal to the City Council with the following conditions: 1. All representations of the applicant shall be considered conditions of approval. 5 2. The applicant shall submit all requirements of final plat in accordance with the Aspen Municipal Code (old Code). 3. The applicants shall be responsible for the replacement of any service lines (water and sewer) to the property which need repair or replacement . � �--AY"-\ 4. The applicant shall submit drainage plans which retain historic flow rates on the property. 5. The applicants__ shall ---pave --the _alley_ . way which accesses -the parcel. CH. CBS R MEMORANDUM TO: Aspen Planning and Zoning Commission FROM: Tom Baker, Principal Planner J6 RE: Aspen Villas PUD Amendment DATE: June 29, 1988 SUMMARY: Staff recommends approval of the requested amendment with conditions. APPLICANT: Aspen Villas Townhouse Condominium Association APPLICANT'S REPRESENTATIVE: C. Welton Anderson LOCATION: Eighth Street between Hallam and Main,(see exhibit 1). ZONING: R-MF PUD, (see exhibit 1): PARCEL SIZE: 100,188 square feet, excluding the steep slope and valley floor. NEIGHBORHOOD CHARACTERISTICS: This development is part of Aspen's west end neighborhood. The neighborhood is essentially a mix of single-family and multi -family residential with nearby lodge and restaurant uses along the SH 82/Main Street corridor. APPLICANT'S REQUEST: PUD Amendment, (see exhibit 2). The applicant proposes to update the design of the Villas, to remedy some existing design flaws and to provide the opportunity for modest expansions at the option of individual owners. This would include enclosing of existing balconies and expanding existing bedrooms and living areas; new decks may also be added and carports similar to the type found in Snowmass Village are proposed. REFERRAL COMMENTS: The Engineering Department states that the plat must conform with the Municipal Code, (see exhibit 3). STAFF COMMENTS: The criteria which the staff will use to evaluate this amendment as provided in the new Code, is whether the amendment is consistent with the basic intent of the original PUD. The record of the original intent of this PUD is incomplete; however, the staff feels that the intent was to cluster the housing and parking to create a multi -family environment which takes best advantage of open space associated with the development. More specifically, staff will review the amendment's effect on character, visual impact, landscaping, FAR, density, open space and transportation impacts. Character- The staff finds that the proposed changes to the PUD do not compromise the general character of the development, that is the development will still be a multi- family, clustered, residential development similar in scale to what currently exists. Visual Impact- Staff feels that the view from Hallam Street provides the greatest exposure to people travelling through the area and, therefore, the Hallam units have the greatest potential for visual impact. The staff feels that the architectural changes to the residences will not be negative and that since carports are not proposed for the Hallam Street parking lot there will be no negative visual impact created by this development. Landscaping- This proposal will not effect existing vegetation, although it is possible that plant material may be damaged during construction. The applicant also proposes to construct a carport on the east property line which will require variance in the side yard setback. Staff suggests that the applicant provide the Engineering Department with drawings of this proposal, including topography, to determine if the right-of-way is negatively effected. FAR- Even with full buildout of this proposal the development would be under allowable FAR. Under Plan C the floor area (including basements) would increase from 63,360 to 71,280, a 12.5% increase. This seems like a significant increase, however, it is still considerably below the FAR of 1:1 allowed in the R-MF zone. Density- The applicant is proposing no expansion in unit count, so there is no effect on the development's density. Open Space- In staff's opinion the applicant's proposal does not significantly reduce the development's open space. Transportation- This proposal will not create additional automobile trips. RECOMMENDATION: Staff recommends approval of the PUD Amendment for the Aspen Villas with the following conditions: o any landscape material destroyed during construction will be replaced with comparable or better material. o the applicant provide t e Engin ering epartmept with cons ction d wing of/ e carp rt, r t ining fall and berm so th Engi ee 'ng ep rt ent can determine that no impacts t r-o-w ill be creat o Prior to the issuance of a building permit the 2 applicant shall, to the satisfaction of the Engineering Department, submit a Final Plat which conforms to the requirements of the Municipal Code. 3 Page Two To avoid the case by case, piecemeal approach that you are familiar with on the additions to the Aspen Club condos P.U.D. , we are re- questing to have the full buildout ( Plan C) for all units approved. In this fashion, the City can look at the impact of the maximum potential at buildout at once, and individual owners (most of whom are local employees) won't have to make individual applications to the City at a cost of $1570 each to add 140 square feet to their living room. Carports: In the parking lot off the 8th street loop there is an ideal location for providing covered parking for approximately 18 cars. On either side of the entrance off of 8th street is a berm approximately 4' high that now shields the parking lot from the street. The berm is entirely in the public Right -of -Way but has been landscaped, sprinklered, and maintained by the Villas for 16 years. We propose to construct a 4 to 5 foot retaining wall along the east property line between the existing pavement and the berm. Approximately 2 to 3 feet above the retaining wall and supported on columns, a shed roof will extend 20 feet to the west and cover 6 cars on the south and 12 cars on the north of the entry. The berm will be slightly recontoured to rest against the retaining wall and additional landscaping provided to screen the carport roof. This approach will require a variance in the side yard setback to allow construction of the east wall of the carports on the property line which can be granted as part of the P.U.D. amendment. In reality, the perceived side yard along 8th street (which is 35 feet deep at its minimum) will be essentially unchanged. VISUAL IMPACTS: The area of main concern is the view of the Villas from State Highway 82. Currently the complex looks like a group of very uniform and rather boring structures that look vaguely threatening with their pill -box gun slot balconies perched on the edge of the Castle Creek bluff. The homeowners wish to update the look of the complex with the plan A up grade and add visual interest and variety by providing standards for Plans B and C. The visual impact on the Castel Creek Bluff is already there. We feel these alterations and small additions will provide a more positive image of the Villas as one enters Aspen. Carports: The area where these would be visible is the one block segment of 8th street that connects the west ends of Main and Bleeker Streets. All one would see is the fascia of the shed roof 2 to 3 feet above the berm and screened by mature landscaping. F. A.R.: Not counting the land owned by the Association of the steep slope and in the valley floor of Castle Creek, the flat area above totals 2.3 acres or 100,188 square feet. Counting basements at 1000, the total existing floor area is 63,360 square feet. The full Plan C addition adds 80 square feet upstairs (fully enclosing both balconies) and 140 square feet downstairs for a total of 220 square feet. If all 36 townhouses opted for Plan C, it would add 7920 square feet for a total of 71,280 square feet, well below the 1 : 1 allowed on a 100,188 square foot RMF lot. Carports: Total square footage of covered parking is 3360 square feet. Even if parking is counted in F.A.R. , it will not exceed what is allowable.
