FILE STATUS AND LOCATION: MEMORANDUM TO: Stan Clauson, City Community Development Director FROM: Kim Johnson, Planner RE: Amendment to the Hirsch Stream Margin Review as an Exemption from Full Stream Margin Review DATE: May 11, 1995 SUMMARY: Tom and Maureen Hirsch wish to amend the approval of stream margin granted in June of 1994 for the parcel located at 635 Sneaky Lane. The revised plan for the single family residence meets the criteria for exemption set forth in Section 24 -7 -504 (B) of the land use regulations. The structure exceeds 85% of allowable floor area and was reviewed and approved by the FAR Overlay Committee on April 25, 1995. FINDINGS: The original Hirsch Stream Margin review was approved by the Planning and Zoning Commission on June 21, 1994 with 6 conditions of approval. A building permit was subsequently issued. This stream margin exemption application indicates that the changes to the structure reduce its footprint on the site by 764 s.f., eliminate the removal of many young aspen trees, and substantially reduces construction impacts to an 8 inch caliper spruce on the west side of the building. Please refer to the attached drawings and application letter for the applicant's response /development data. Review criteria in Section 7 -504 (B) reads: 1) the development does not add more than 10% to the floor area of the existing structure. response: The 1994 approval was for a 4,800 s.f. structure. The building approved at the FAR Overlay review is 4,850 s.f. The additional 50 s.f. represents a one percent increase. 2) the development does not require the removal of any tree for which a permit would be required, or the applicant receives a permit by the Parks Department; and response: The revision better protects many trees on site. Any which have to be removed will receive the necessary permits. 3) the development is located such that no portion of the expansion, remodeling or reconstruction will be any closer to the high water line than the existing development; and r^. than the 1994 approval. 4) the development does not fall outside of an approved building envelope, if one has been established by prior review; and response: The 1994 approval did not establish an envelope. 5) the development will cause no increase in the amount of ground coverage of structures within the flood hazard area. response: The structure is located outside of the flood hazard area. Staff has reviewed the revisions to the building and site and finds that the above criteria have been satisfied. The 1994 approval was granted subject to conditions. These shall also be carried forward to the revisions approved for this exemption. RECOMMENDATION: Staff recommends that the Planning Director approve the Hirsch Stream Margin Exemption finding that the criteria in Section 7 -504 (B) have been met. The following conditions apply to this approval: 1. All drainage from impervious surfaces must be maintained on- site at historic rates and cannot enter either Sneaky Lane or the stream. Construction documents must specify that any subsurface drainage shall not enter the stream. 2. Any new landscape planting or development in the rear yard must be reviewed by the Planning Office and shall consist of native species found in the river area. 3. All trees 6" caliper and greater in the construction area must be protected by sturdy barricades erected at the driplines. This is crucial for the 8" spruce at the southwest part of the house. 4. A silt fence (hay bales or similar method) shall be placed no closer than 5 feet from the river's edge to prevent sediment and debris from entering the river. 5. The riverbank easement and other pedestrian easements along the side and front of the parcel must be shown on the building permit site plan /survey. I hereby approve Stream Margin Exemption for the Hirsch residence located at 635 Sneaky Lane as conditioned above. 2 C trsr Sta City Community Development Director ,y Date Application Drawings and Letter 3 W - — - 14.11 � 44, l - 8888 _z� EGF fF v_t. 1 i� st�'� SGx. , y � _ .` f 7>c'nn� :a n0> rn o n - 'm 7i ? n ='r qu1Rf /d c 5 b a \i A p e R s _ m xaiim s- P t. t ti 12 Jm p mxir ' SNP} I , �� c. a MsWnuuaow -. \9 ,4 --pfd i ll 99' i / S i P P P O 'n l ft.

The project does not increase the amount of building area exempt from floor area calculations by more than 25 %. 25% of the building area (20,880 sf) equals 5,220. The project equals 4,850 sf. 2. The project does not require the removal of any tree for which a permit would be required. 3. The project is located such that no portion of the expansion, remodeling or reconstruction will be any closer to the high water line than is currently existing. The project expands 9' -0" to the east from the existing dwelling and is 9' -0" from the eastern 10' -0" required setback line. 4. The project does not fall outside of an approved building envelope; in fact, the revised plans have reduced the overall footprint of the originally submitted building envelope by 750 sf. 5. The project is located completely outside of the Special Flood Hazard Area and more than one hundred feet (100') measured horizontally, from the high water line of the Roaring Fork River; and will not cause any increase to the amount of ground coverage of structures within the Special Flood Hazard Area. Thank you. \V E • PROJECT: Building Permit # 4 -462, approved October, 1994 Stream Margin Review approved, June, 1994 Hirsch Residence 635 Sneaky Lane Aspen, CO TO: Aspen Planning & Zoning Kim Johnson RE: Revisions to Design (permit # 4 -462) Dear Kim, As discussed during our last meeting, I have been retained by Tom and Maureen Hirsch to improve the environmental conditions which were not addressed in the original architectural plans submitted to the Building Department. We fully recognize that a building permit has been granted for the original design (permit #4- 462), and that the Stream Margin Review has been approved for this original design. However, our new efforts to improve the design will not impact the Stream Margin Review in any way; in fact, we hope, will enhance the site as outlined below. Enclosed are the required site plan, elevations, and plans for your review. I am hopeful that you can expedite the process of building permit review considering the previous approvals. If you have any questions, please call me. Thank you very much. I. Revision Goals: 1. Reduce overall footprint on the property in order to save existing trees, sustain natural environment for aesthetics, solar shading, ground run -off, etc., reduce building costs, improve efficient use of existing building and conservation of materials and demolition /waste removal. The current revised design reduces the overall footprint by 746 sf or 4% from the original submitted plans currently permitted for construction. 2. Add no physical changes to the design which would impact the Stream Margin Review approval. The revised design does not add any square footage on the north side or stream side; and, in fact, reduces overall footprint square footage as noted above, by 746 sf. 3. Reduce removal or destruction of existing trees. The revised design eliminates construction proposed in the earlier design which threatened an existing 8 -inch diameter spruce; in addition, the new design saves another 14 smaller diameter aspens and cottonwoods which would have been removed in the earlier design. 4. Improve daylighting design, energy efficiency, water conservation, and indoor air quality. The revised design omits earlier design features which would have blocked solar access and daylighting into the home, affecting cross ventilation, views, and energy performance. The revised design utilizes more compact design shapes and building envelope efficiencies which will improve energy performance. Specifications and re- locations of bathrooms and fixtures will improve water conservation. Strategic demolition specified in the new design will help mitigate current mold and mildew problems, as well as non -toxic building material selections now specified, such as no -VOC paints, low VOC carpeting and wood finishes, HEPA filtration, cotton insulation, to mention a few. o1 1 �w g g m . a, . i Is d ! o {n VY � V QO i v au t ^ p O" F C G S u; •• i ll ill .l wogs!

EXISTING CHARACTER OF SNEAKY LANE, ASPEN, COLORADO The street is located north below the HWY 82 bridge leaving Aspen toward Basalt. Sneaky Lane is at the furtherst west end of the West End neighborhood. It is adjacent to Castle Creek and has only one entry road, off Plant Road. By nature of its lower elevation and being off the beaten path, it is nestled, literally, below Aspen proper, with characteristics of being very quiet from road traffic and enjoying great privacy. Most homes on Sneaky Lane have Castle Creek frontage and consequently most homes orient their major views in this direction, which is away from incoming neighbors or guests. The homes (approximately 9 total) are built close to the aspen and cottonwood stands, and therefore, are not easy to see until one is quite close to them. The architecture is varied, but the majority use light grey wood siding to blend with the trees; the roof lines are angled and pitched; few, if any, have flat roofs. Most properties are heavily wooded and have generous space between boundaries. Windows tend to be smaller in scale towards the street side, while use larger glass sizes on the Creek side, thus giving a residential scale to the public while offering grand views of nature and the Creek on the private exposures. HIRSCH PROPOSED DEVELOPMENT OF EXISTING HOME Our existing home is ugly, in our opinion, and does not contribute to the beautiful architectural character of Aspen or of our street. It has very low- pitched roofs, so much so, that the roof must be surface - treated like a flat roof; over the years this material has failed, and the roof leaks in many locations. Two abandoned solar collectors sit on the roof and are unsightly. The original garage space has since been converted to other uses, and therefore cars must be parked outdoors which is not appealing. The views of Castle Creek are limited and strained by the use of small windows. The interior ceilings are tall cathedral, but dark. Consequently, the home environment is uncomfortable and does not take advantage of the beautiful views surrounding it. Our proposal is to renovate the existing home without major demolition of the existing structure except the roof, in essence keeping the existing footprint in tact. In order to correct the roof leaking problems and create a more attractive roof -line, we are designing a more elegant pitch to the roof and applying roof shingles similar to those seen around Aspen. While we are removing the solar panels, we are improving natural daylight throughout by using clerestory windows wherever possible, instead of skylights. We are converting the existing garage back to a garage for cars and building a second story above it to make the garage structure into a more integrated look while giving us the guest room space formerly in the first floor of the old garage. To accommodate our growing family, we are building a small addition wing to the east, which balances the garage wing to the west. This design focuses the entrance directly in the middle. We plan to landscape the current "front yard ", which serves as car parking, with more aspens and cottonwoods. In fact, we plan to remove no more than three existing trees with trunk diameters of 5 -6- inches. On completion, there will be more trees than presently exist on our parcel. We have retained The Masters Corporation, an environmental architectural and construction firm, which specializes in environmental homes around the country. They will be concentrating on energy - conservation design techniques, water- conservation appliances and fixtures, and low toxic building materials throughout. There will be little use of formaldehyde products, no chemical pesticides, herbicides, and low -VOC products (volatile organic compounds). During demolition, products and interior cabinetry will be salvaged wherever possible, rather than carted to waste disposal. Some of the existing wood vertical siding will remain, in this effort to salvage, while the new siding will switch to horizontal wood siding. All windows and doors will be wood, painted or stained, in wood or natural colors. The upper portion of the windows and doors will have muntins or grills, which give the home a very residential character. The overall intent of our project is create a magical home for our family to live and grow in, to create a home which blends into the neighborhood and the natural surroundings, to create a home which embraces the creek outside our main living areas, and to create a home which promotes environmental design, high standards for indoor air quality, and integration of environmentally sensitive building materials and techniques. We also hope to achieve this dream within our budget. rCi err 1 LAND USE APPLICATION FORM 1) Project Name HIRSCH RESIDENCE 2) piuject Location 635 Sneaky Lane, Lot 2, Section 12 Township 10 South, Range 85 West of the 6th P.M.
