Industrial Zones

After April 1, 2022

Current Ordinance

In the Zoning Ordinance effective April 1, 2022, the industrial zones have been consolidated from five zones to two zones, which allow for either light industrial and employment areas or heavy manufacturing and industrial activities in other areas. See descriptions and purposes of the new zones below and reference the Zoning Ordinance for full details. 

IE: Industrial, Employment Zone

The purposes of the Industrial, Employment (IE) Zone are:

  • To provide for a mix of employment, research and development, and light industrial development, with an expectation of high-quality design that is set apart from the high-traffic-generating commercial zones and residential communities
  • To provide lands to serve light industrial uses while prohibiting more intensive forms of industrial development
  • To accommodate limited residential development
  • To ensure compatibility between industrial development and nearby residential uses

IH: Industrial, Heavy Zone

The purposes of the Industrial, Heavy (IH) Zone are:

  • To provide lands for intense industrial development that generally requires large sites, as well as industrial uses that are important for the County’s economic growth but may impact adjoining lands. Such uses generally involve greater potential for adverse off-site impacts on the environment and surrounding development (e.g., from dust, fumes, smoke, odors, noise, or vibration, or due to exterior movement of vehicles, materials, and goods)
  • To accommodate limited residential uses, particularly as adaptive reuse opportunities
  • To mitigate potential impacts to surrounding residential neighborhoods
