In addition to information obtained from the American Planning Association.and Innovations Group, zoning ordinances.and related materials were collected from several communities including the following: Aurora,Barrington,Bolingbrook- Downers Grove,.Dublin (Ohio),Elgin,Highland Park, Hinsdale, Hoffman Estates, Lake Forest,Lombard, Orland Park, Schaumburg,Warrenville, and Wheaton. The "Comparative Zoning Summary" below provides a.summary of our findings. [Return to ton ofnage]_ COMPARATIVE ZONING SUMMARY This section provides a brief analysis of how Naperville's residential bulk regulations for the R2 and RIB Zoning Districts (primarily those areas impacted by.the teardown.phenomenon)compare against standards utilized by other communities. This section focuses on traditional bulk regulations related to lot size, lot.. . width, floor area, and setbacks. A summary matrix of this information has been.prepared and is included in this report. . , Lot Size. Napery'Ile's minimum lot size requirements are generally consistent with the lot size requirements contained in other municipalities' zoning ordinances, although few comparative examples could be found for the R2 Single-Family and Low Density Multiple-Family.District. Lot Width The minimum lot width requirement of 50 feet for the R2 district is generally consistent with other communities surveyed, although two of the five communities surveyed required lot widths of 80 feet. The lot width requirement of 50 feet in the RIB district is lower than the standards utilized by most of the communities surveyed, which generally range between 60 and 75 feet. Maximum Building�Height/BuiIding Stories The maximum building heights.(40 feet or 3 stories in the R2 district and 35 feet or 2.5 stories in the RIB district) contained in Naperville's Zoning Ordinance are generally consistent with the standards contained in other municipalities' ordinances. However, seven of the communities surveyed were more restrictive in controlling building height and allowed buildings to a maximum height between 25 and 30 feet.
