CE
Commercial Employment Zone
The Commercial Employment CE zone is a medium-scale zone intended for sites along corridors with a Neighborhood Collector or higher traffic classification, especially along civic corridors that are also Major Truck Streets or Priority Truck Streets. This zone is generally not appropriate in designated centers, except on a site that is currently developed in an auto-oriented manner and where more urban development is not yet economically feasible. The zone allows a mix of commercial uses, including auto-accommodating development and drive-through facilities, as well as some light manufacturing and distribution uses that have few off-site impacts. The emphasis of this zone is on commercial and employment uses, but residential uses are also allowed.Buildings in this zone will generally be up to four stories tall. This zone is intended to allow for development with auto-accommodating configurations, while also including pedestrianoriented design features that support transit and pedestrian access.
