Bruce Kerr, Chairman MEMORANDUM TO: Planning and Zoning Commission FROM: Kim Johnson, Planner RE: Transierra Stream Margin Review DATE: December 7, 1993 SUMMARY: The Planning Office recommends approval of this Stream Margin Review with conditions. APPLICANT: Transierra Corporation, represented by Kim Weil LOCATION: 1410 Red Butte Drive (Lot 7, Block 1, Red Butte Subdivision). The parcel is 37,812 s.f. and is zoned R -30. APPLICANT'S PROPOSAL: The owner plans to expand the existing single family residence. The location of the home and expansion require stream margin review. An accessory dwelling unit was approved for this home in 1993. The revised plan relocates the ADU in the structure but staff has determined that the change does not require additional review by the Planning Commission. Please refer to the application text and drawings, Exhibit "A ". A more detailed site plan will be presented by the project architect at the P &Z meeting. REFERRAL COMMENTS: Referral memos are attached as Exhibit "B ". Engineering states that more specific information is required regarding soils erosion protection into the river. The Parks Department requires tree removal permits for any trees over 6" in diameter. Also, trees should be protected from digging or soil placement within the dripline. A ten foot fisherman's easement along the river's edge is requested. The Housing Office supports the changes to the ADU because a larger unit is created in a better location on the property. STAFF COMMENTS: Any proposed development within 100' of the high water line or within a flood hazard area must receive Stream Margin approval. Stream Margin applications are reviewed by the Planning and Zoning Commission according to the standards set forth in Section 24 -7 -504 of the Aspen Municipal Code. 1. It can be demonstrated that any proposed development which is in the Special Flood Hazard Area will not increase the base flood elevation on the parcel proposed for development. This shall be demonstrated by an engineering study prepared by a professional engineer registered to practice in the State of Colorado which shows that the base flood elevation will not 1 be raised, including, but not limited to, proposing mitigation techniques on or off -site which compensate for any base flood elevation increase caused by the development. response: Per Schmueser, Gordon, Meyer Engineers, the flood plain is below the area of construction, so the base flood elevation will not be affected. 2. Any trail on the parcel designated on the Aspen Area Comprehensive Plan: Parks /Recreation /Open Space /Trails Plan map is dedicated for public use. response: No trail is identified for this side of the river. However, the Parks Department and the Roaring Fork Greenway Plan recommend voluntary dedication of a fisherman's easement along the edge of the high water line of the river. 3. The recommendations of the Roaring Fork GreenwaY Plan are implemented in the proposed plan for development, to the greatest extent practicable. response: The applicant will take all practical measures to minimize disturbance to the land. The mature trees along the crest of the bank will remain undisturbed. Parks and Planning recommend that existing vegetation be protected against excavation and soil fill. A condition requiring barricades around the driplines has been included for approval. The backyard will otherw' - remain basically as it is now. 4. No vegetation is removed or slope grade changes made that produce erosion and sedimentation of the stream bank. response: The slope will remain undisturbed. The applicant tmust provide detailed erosion control methods at building permit ENgineering and Planning will review these methods. 5. To the greatest extent practicable, the proposed development reduces pollution and interference with the natural changes of the river, stream or other tributary. n response: Erosion control methods will be made to l it p l utio during construction per approvals of building p it P changes will be made to the water course. 6. Written notice is given to the Colorado Water Conservation Board prior to any alteration or relocation of a water course, and a copy of said notice is submitted to the Federal Emergency Management Agency. response: Not applicable as the water course will not be changed. 7. A guarantee is provided in the event a water course is altered 2 2 or relocated, that applies to the developer and his heirs, successors and assigns t not dim finished the flood carrying capacity on the parcel response: Same as no.6. 8. Copies are provided of all necessary federal and state permits relating to work within the one hundred (100) year floodplain. response: Not applicable STAFF RECOMMENDATION: The Planning Office recommends approval of the Transierra Stream Margin Review with one condition: Prior to the issuance of any building permits: 1. Specific information is required regarding soils erosion protection into the river. 2. The Parks Department requires tree removal permits for any trees over 6" in diameter. 3. Existing trees in the rear yard shall be protected from excavation or soil placement within the dripline by means of protection barricades. These shall be identified and detailed on the building permit site plan /landscape plan. 4. All material representations made by the applicant in the application and during public meetings with the Planning and Zoning Commission shall be adhered to and considered conditions of approval, unless otherwise amended by other conditions. airti 6 •O Attachments: "A" - Site Plan "B" - Referral Comments 3 3 <:ANN a NG & ZON11...� wri •.iSSZON EXHIBIT 4 , APPROVED 19 _ BY RESOLUTION 2Eq hp. q4'' 605 EAST MAIN STREET ASPEN.

Galena Aspen, CO 81611 RE: TRANSIERRA RESIDENCE STREAM MARGIN REVIEW AND AMENDMENT TO ADU APPROVAL Dear Kim, Transierra Corporation, the owner of the house located at 1410 Red Butte Drive, is planning to remodel and expand the existing structure. Due to revisions made to the design of the addition, the location of this ADU has changed from the original scheme to a more advantageous position on the southwest side of the house. Also, the location of the addition to the existing residence will necessitate a stream margin review for the property, which we will show is in full compliance with the review standards for development in the stream margin. During our hearing for the original ADU approval there were some concerns expressed about the availability of natural Tight and about access to the unit being limited due to snow buildup. Our new location provides not only abundant natural light, but also an easier and more direct access into the unit. In addition, the new location provides more privacy from the main residence than the previous scheme and the possibility of a separate yard space to the west. We have also had more flexibility in the arrangement of the interior and have been able to better utilize the available floor area to make a one bedroom apartment rather than a studio as originally proposed. 0 TRANSIERRA RESIDENCE 10/15/93 The majority of the remaining addition will be located along the northwest side of the existing house, in line with existing construction. We will be adding a basement in this area as well as renovating the two existing bedrooms on the main floor and the master bedroom above. We will also be expanding the area of the existing Dining Room toward the property line to the east and infilling the existing gravel court between the Garage and the Dining Area. Some additional area will be added to the southwest side of the Garage as well. In none of these additions will we be building closer to the river, nor will we be affecting either the bank, the existing vegetation, or the natural water course. We feel that for these reasons and because of the improvement to the aesthetics of the existing house that will result from our revised scheme, our stream margin development application should be approved. Please review the enclosed information and feel free to call if you have any questions. We would appreciate your scheduling a planning and zoning review for us as soon as possible. Sincerely, j 5 a Kim Weil Project Manager 93131015.Itr and associates 605 EAST MAIN STREET ASPEN, COLORADO 81611 TELEPHONE 303 925 -4 755 FACSIMILE 303920 -2950 TRANSIERRA RESIDENCE DEVELOPMENT IN THE STREAM MARGIN A. It can be demonstrated that any proposed development in the special flood hazard area will not increase the base flood elevation of the parcel. RESPONSE: Please see enclosed analysis by Dean Gordon of Schmueser, Gordon, Meyer. B. Any trail on the parcel designated on the Aspen Area Comprehensive Plan map is dedicated for public use. RESPONSE: No such trails exist on the property. C. The recommendations of the Roaring Fork Greenway plan are implemented to the greatest extent practicable. RESPONSE: The recommendations of the Roaring Fork Greenway plan are being implemented in that we have made no changes to the natural topography or vegetation along the river bank. D. No vegetation is removed or slope grade changes made that produce erosion and sedimentation of the stream bank. RESPONSE: No vegetation will be removed along the stream bank, and no new grading will occur along the bank. E. To the pollution r and interference with practicable reduces the natural changes of the riiver . RESPONSE: In order to offset any possible effects of excavation and construction, we will try to block runoff from going directly in to the river with haybales or whatever means necessary to avoid soil pollution of the river. and associates TRANSIERRA RESIDENCE DEVELOPMENT IN THE STREAM MARGIN F. Written notice is given to the Colorado water conservation board prior to any alteration or relocation of a water course. RESPONSE: No alteration or relocation of the water course is proposed. G. A guarantee is provided in the event a water course is altered or relocated that the flood carrying capacity on the parcel is not diminished. RESPONSE: No alteration or relocation of the water course is proposed. H. Copies are provided of all federal and state permits relating to work within the one hundred year flood plain.

As a basis for this analysis, I conducted a field investigation, reviewed the site topographic survey prepared by your office and reviewed the existing FEMA mapping for the Roaring Fork River immediately adjacent to the property. The FEMA study is entitled "Flood Insurance Study, Pitkin county, Colorado and Incorporated Areas ". It appears that the only portion of property that may be in the floodplain is the area immediately along the river bank and centered on the existing building footprint. The FEMA study confirms that the 100 year floodplain is basically contained within the bank area, that area immediately adjacent to the bank in this area. My understanding of building modifications would include second story decks with associated support structures to the rear building of the t building itself t the building. None of these proposedmod modifications ons would be inthe100 year f oodpla n t of I have attached copies of those portions of the FEMA study associated with this property for further reference. I remain available to provide further information as required. Respectfully submitted, SCHMUESER GORDON MEYER, INC. /or g" 1 Dea $ . Gordon, '.E. Pr > -ident D Gra' .8 \FOLD FOLD G F 0 ° .
