Shall the General Plan of the City of Chino be amended to change the land use designation of 5.6 acres of vacant land- generally located at the southwest corner of Schaefer Avenue and Roswell Avenue- from "Business Park" to "Residential-RD20" so that the City Council can re-zone the parcel from IPD-BP (Industrial Planned Development- Business Park) to RPD-RD20 (Residential Planned Development- RD20) for the purpose of providing senior citizen housing?
