A. Purpose Statement: The purpose of the M-1 Light Manufacturing District is to provide an environment for light industrial uses that produce no appreciable impact on adjacent properties, that desire a clean attractive industrial setting, and that protects nearby sensitive lands and waterways. This zone is appropriate in locations that are supported by the applicable Master Plan policies adopted by the City. This district is intended to provide areas in the City that generate employment opportunities and to promote economic development. The uses include other types of land uses that support and provide service to manufacturing and industrial uses. Safe, convenient and inviting connections that provide access to businesses from public sidewalks, bike paths and streets are necessary and to be provided in an equal way. Certain land uses are prohibited in order to preserve land for manufacturing uses and to promote the importance of nearby environmentally sensitive lands.
