The purposes of the C-1 district are to: create a thriving commercial district; encourage low-impact commercial development; promote diversity in services and accommodations; encourage year-round commercial uses that serve the needs of the community; and reuse of valuable historic buildings to expand commercial use.

The C-1 regulations recognize the predominance of residential uses by continuing to permit single- and two-family residential, while encouraging commercial by providing zoning incentives for such uses.

The purpose of allowing residential and professional offices above ground floor retail is to increase the viability of the property by creating continuous activity. Residential units above commercial also provide a realistic opportunity for affordable housing.
