ORDINANCE NO. MC-202-98
AN ORDINANCE AMENDING THE PROVISIONS OF THE WINNETKA ZONING ORDINANCE PERTAINING TO BUILDING HEIGHT, INTENSITY OF USE, AND PARKING IN THE MULTI-FAMILY RESIDENTIAL ZONING DISTRICT
WHEREAS, in the spring of 1996, the Plan Commission of the Village of Winnetka began working on revising the Winnetka Comprehensive Plan; and
WHEREAS, the Village of Winnetka has entered into a contract with Thompson, Dyke & Associates to work with the Plan Commission and Village staff in developing the revised Twenty Year Comprehensive Plan; and
WHEREAS, the work under the Thompson, Dyke & Associates contract has included conducting a preliminary analysis of the zoning regulations in the B-1 and B-2 Multi-Family Residential Zoning Districts; and
WHEREAS, the work on the revised Comprehensive Plan has also included conducting focus group sessions, conducting a written survey of all Village residents, and consulting with various professionals in the fields of architecture, land use, and economic development; and
WHEREAS, the Council of the Village of Winnetka have received and considered the March 2, 1998, recommendations of the Plan Commission on the multi-family zoning regulations, which were submitted after considering the February 17, 1998 consultant memorandum of Thompson, Dyke & Associates pertaining to multi-family zoning regulations in the B-1 and B-2 Multi-Family Zoning District and the documents referenced in that memorandum; and
WHEREAS, the Plan Commission has recommended that the zoning regulations applicable to the multi-family zoning districts be amended to reduce the maximum allowable building height, to lower the maximum number of dwelling units allowed per acre, to increase parking requirements, to establish a maximum permitted floor area ratio, to reduce the maximum permitted lot coverage; and
WHEREAS, Thompson Dyke & Associates has made specific recommendations as to limits and requirements recommended by the Plan Commission and has further recommended the elimination of the B-2 Multi-Family Zoning District and the creation of a townhouse zoning district; and
WHEREAS, the Village Council have determined that the recommended elimination of the B-2 Multi-Family Zoning District and the recommended creation of a townhouse zoning district require further study and have accordingly directed the Village staff to draft an ordinance that amends the use, bulk and parking regulations of the B-1 and B-2 Multi-Family Zoning Districts, limits the multi-family uses permitted in the C-1 (Limited Retail) Zoning District, and that retains the existing zoning district boundaries and classifications; and
WHEREAS, on March 17, 1998, on due notice thereof, the Winnetka Village Council, sitting as a Committee of the Whole, conducted a Public Hearing to consider the proposed amendments; and
WHEREAS, the Council of the Village of Winnetka have determined that the standards in the B-1 and B-2 Zoning Districts pertaining to maximum building height, set backs, density, intensity of use of lot, maximum building size and parking requirements for permitted multi-family buildings should be reduced from their existing levels in order to encourage the development of property in the B-1 and B-2 Zoning Districts as a buffer between single family residential zoning districts and adjacent commercial districts and major traffic corridors; and
