L2 L3 B2 Two Duplex DesignTown of Avon Final Design Staff Report April 7, 1998 Planning & Zoning Commission meeting Report date April 2, 1998 Project type Two Duplexes Legal description Lots 2 and 3, Block 2, Wildridge Subdivision Zoning PUD Residential - 2 units per lot Addresses 3150 and 3170 Wildridge Road Introduction The two duplex buildings are being presented as one project, even though they are on separate lots. The applicant is taking this approach because the lots share a common access: Lot 2 is adjacent to Wildridge Road, and access to Lot 3 is provided by an easement through Lot 2. The slope is approximately 60 percent at the point where the driveway will enter the property. The building pads have slopes of approximately 24 percent. The duplexes are contemporary style, with two stucco colors separated with a trim board and wood siding. The buildings feature large gabled ends. History The Planning and Zoning Commission reviewed the concept plan for the project on March 17th. The Commission and staff made the following comments. 1. The duplexes are designed with a "weak" attachment. While this provides a more articulated massing of the buildings, it results in more site disturbance including wider coverage by the buildings. 2. The design results in moderate site disturbance with cuts up to six feet. The buildings have been sited for optimal views. Siting the buildings more parallel to the slope may help to minimize site disturbance. 3. The driveway connection must be perpendicular to Wildridge Road. 4. Grading on north side of Unit 2 will result in drainage against the wall. 5. The driveway at Unit 1 has a low spot that will be unable to drain. 6. Site disturbance is proposed up to the southern property line. Care will need to be taken during construction to ensure that the neighboring property is not disturbed. 7. Trees should be added for screening on the north and east side of Unit 3. 8. Final drainage to be approved by staff.

They have submitted a letter from a geo-technical engineer affirming that the underlying rock will be able to support the proposedl/2:1 rock slope. 2. They have added two trees on the northeast side of Unit 3. 3. They have reduced the size of the units to minimize site disturbance. 4. They have re -aligned the driveway entrance to a 90 -degree angle intersecting the slope. Modification of the drainage will need to be completed with the building permit submittal. Design Review Considerations According to the Commission's Procedures, Rules & Regulations, Section 6. 10, the Commission shall consider the following items in reviewing the design of this project: 1. Conformance with the Zoning Code and other applicable regulations of the Town. • Allowed use: Conforms with the allowed residential use. • Density: Duplex use conforms to each lot's 2 dwelling unit designation. • Lot Coverage: The proposed 11.15% of building coverage conforms to the 50% maximum. • Setbacks: No proposed encroachments. • Easements: An address monument is shown in the Town's right-of-way. This will need to be relocated onto the property during construction. • Building Height: The tallest height of 32 feet on Building 1 conforms to the 35' maximum limit. • Grading: All proposed slopes conform with the maximum of 2:1 slope guideline and the proposed driveway grades conform to Town standards. • Parking: The two garage and one surface parking spaces conform with the required two spaces for each unit. • Snow Storage: Submitted plans show snow storage area equal to the minimum standard of 20% of the proposed impermeable surface area. • Landscaping: There are a large number of native Serviceberry bushes on the site. These should be transplanted on-site after construction. The landscape plan needs to be revised to indicate where they will be transplanted. Landscape screening of the rock wall should also be provided. 2. The suitability of the improvement, including type and quality of materials of which it is to be constructed and the site upon which it is to be located. 3. The compatibility of the design to minimize site impacts to adjacent properties. The driveway cut will be visible from nearby property and roads. The driveway cut is up to 15 feet and is proposed as a natural rock wall. The cut should be screened with landscaping or other treatment to minimize the appearance of this disturbance. 4. The compatibility of the proposed improvements with site topography. The site design results in a moderate amount of disturbance. The driveway cut is necessary due to the 60 percent slope at the driveway entrance and the pre-existing access easement to Town of Avon Community Development \\ntserver\file server\p&z\staff reports\1998\040798\2and3b3wr.doc (970) 949-4280 Fax (970) 949-5749 Lots 2 and 3, Block 2, Wildridge Subdivision, Final Design Review, page 3 April 7, 1998 Planning & Zoning Commission meeting Lot 3. As discussed above, the proposed cut should be screened or otherwise modified to minimize the appearance of this alteration. 5. The visual appearance of any proposed improvement as viewed from adjacent and neighboring properties and public ways. See comments above. 6. The objective that no improvement be so similar or dissimilar to others in the vicinity that values, monetary or aesthetic will be impaired. N/A 7. The general conformance of the proposed improvements with the adopted Goals, Policies and Programs for the Town of Avon. N/A Staff Recommendation Approve with conditions.
