WHEREAS, the Deerfield Residential Redevelopment Task Force (the. "RRTF ") was
formed, among other things, to examine the recent trend to redevelop the Village's existing single-
family residential housing stock with larger, taller houses and home additions, to address concerns

existing houses in such neighborhoods, and to recommend any changes to the Zoning Ordinance of
the Village of Deerfield that may necessary or appropriate to protect the public health, safety and

Ordinance Village of Deerfield be amended and adopted as provided herein to control the permitted
bulk of new construction in the residential zoning districts of the Village of Deerfield by redefining
the manner in which the maximum height of a house is determined, by establishing a maximum
floor area ratio building size, and by restricting the bulk of houses at the side yard setback line; and,
WHEREAS, the Plan Commission of the Village of Deerfield held a public hearing
pursuant to public notice to consider said proposed amendments, said hearing and notice
conforming in all respects, in both manner and form, with the requirements of the statutes of the
