C. HEARING DATE: September 10, 1996 REQUEST: Amend Exhibit "B" of Ordinance No. 91500-A-104 to add specific provisions regarding the construction of storage buildings, carports and garages. DISCUSSION: '~special committee studied the area, met and discussed possible recommendations. A preliminary report of the committee _, _ \..~ \~ consensus is attached. Subsequent e Planning and Zoning Commission met in a workshop session to discuss the proposed ordinance amendment in greater detail. Staff greatly appreciates the time and energy both groups devoted to the evaluation of the issues involved. RECOMMENDATION: Staff supports the proposed amendments. ALTERNATIVES: 1) Approve the proposed amendments 2) Disapprove the proposed amendments 3) Modify the proposed amendments 4) Continue the public hearing ATTACHMENTS: 1) Original Committee Report 2) Proposed text amendments Item # 4 Report of the Woodridge Advisory Committee July 9, 1996 Carports and Garages for PD-145-R The Committee consisted of two owners of property within the area to be affected, one resident and one non-resident; plus two resident owners of property within the larger Woodridge neighborhood, both officers of the Woodridge Homeowners Association; and two members of the Coppell Planning and Zoning Commission, as follows: Susan Blackwood Rick McCaffrey, Chairman George Redford Gary Daniels Kevin Matheny Hal Sauls Prior to meeting, each committee member inspected and evaluated the six garages and five carports already in place within the planned development district. These are the results of that survey. All six garages were acceptable in terms of appearance, but a garage placed close to the alley was ranked only marginally acceptable in terms of location. The five carports ranked Iow in terms of appearance, with three unacceptable and two only marginally acceptable. As to location, however, the carports were acceptable even when placed close to the alley. Flat roofs were unacceptable. While the group thought that carport and garage roofs should be pitched, they did not think however that the roofs had to be pitched as steeply as the house roof. Roofing material and brick on an added carport or garage should match the roofing and brick on the house. Wood and other materials should be painted to match the paint on the house. Garage doors (with or without garage door openers) need to be farther away from the alley than carports, by at least ten feet. There should be no more than one accessory storage building in addition to a garage or carport. During the committee meeting, the majority agreed that fully enclosed, attached garages were f'~rst preference. However, the group realized that this would not be possible in many cases and that covered parking in other forms may be preferable to uncovered parking in its present state. Following the committee discussion, staff prepared a draft ordinance amendment for each committee member to review and critique.
