L23 B4 WR House DesignTown of Avon Final Design Staff Report February 2, 1999 Planning & Zoning Commission meeting Report date January 29, 1999 Project type Single-family Residence Legal description Lot 23, Block 4, Wildridge Subdivision Zoning Wildridge Planned Unit Development (PUD) — 2 units Address 5591 Coyote Ridge Introduction The applicant describes the project's architecture as characteristic of the "Colorado Mountain Lodge Style". The 4,336 square foot residence with a detached garage/guest room is sited capture both the primary southern views plus views up the Metcalf drainage. Exterior building materials consist of a wall base of dry laid stone and stucco walls. Heavy timbers and wood trim are used to add accents and break up large wall surfaces. The site is located at the end of the Coyote Ridge cul-de-sac. Though portions of the site are extremely steep, the building envelope is less steep at 24%. A 20 -foot wide public access easement exists along the length of the north property line to preserve access to Forest Service lands and Metcalf Creek. Design Review Considerations According to the Commission's Procedures, Rules & Regulations, Section 4. 10, the Commission shall consider the following items in reviewing the design of this project: 1. The conformance with setbacks, massing, access, land use and other provisions of the Zoning Code. • Allowed use: Complies with the allowed residential use. • Density: Single-family use complies with this lot's two dwelling unit designation. • Lot Coverage: The proposed 4.4% of building coverage complies with the 50% maximum. • Setbacks: No proposed encroachments. • Easements: Proposed grading in the 10' Slope Maintenance and Snow Storage Easement is acceptable. Staff believes that the proposed grading in the 20 foot access easement may hinder access (please see consideration # 4 below). • Building Height: The largest determined height of 34.33 feet on the east elevation complies with the 35 foot maximum limit. However, extreme care will be required during construction to ensure the project does not exceed the height limit.

However, staff believes the grading plan must be revised to properly accommodate the driveway culvert. • Parking: The two garage and the two surface parking spaces exceed the required three spaces. • Snow Storage: Submitted plans show snow storage area equal to the minimum standard of 20% of the proposed impermeable surface area. • Landscaping: The aspens at the driveway should provide a positive entryway to the project. However, staff recommends that additional aspens be placed below the structure's south and east elevations. Careful placement of these additional trees can strengthen the project's tie to the site while not overly obstructing desirable views. 2. The conformance with other applicable rules and regulations of the Town of Avon. 3. The type and quality of materials of which the structure is to be constructed. 4. The design of site grading and drainage to minimize impacts to adjacent sites, rights-of-way and easements. The proposed grading in the 20 foot access easement goes beyond this project's property lines. Additionally, the grading appears to create slopes and terrain that may inhibit functional access through this easement. Staff recommends that the grading plan be revised to reduce the amount of cutting within this easement prior to building permit submittal. 5. The compatibility of proposed improvements with site topography, to minimize site disturbance, orient with slope, step building with slope, and minimize benching or other significant alteration of existing topography. The large retaining wall below the southern patio area exceeds the Planning & Zoning Commission's guideline of six feet. The Commission may want to consider whether the height of this wall should be reduced or its apparent height mitigated. Any revisions should be submitted prior to building permit submittal for staff review and approval. If the retaining wall is approved as submitted, it will require a professional engineered design and possibly a safety railing. 6. The appearance of proposed improvements as viewed from adjacent and neighboring properties and public ways, with respect to architectural style, massing, height, orientation to street, quality of materials, and colors. 7. The objective that no improvement be so similar or dissimilar to others in the vicinity that monetary or aesthetic values will be impaired. 8. The general conformance of the proposed improvements with the adopted Goals, Policies and Programs for the Town of Avon. Staff Recommendation Though a few grading issues require refinement, staff believes that these corrections will not significantly affect the project's design. Therefore, based upon the project's general conformance with the above Design Considerations, staff recommends Final Design approval with conditions.
