Conservation Overlay District (CO)

Purpose

A Conservation Overlay (CO) district is applied to areas with unique historic, architectural, cultural or environmental features that warrant tailored zoning standards beyond the underlying base district. It preserves and enhances the defining character of these areas by modifying use, form and design requirements to protect valued resources while allowing compatible development.

Height & Scale

Story RangeHeight and scale requirements are customized for each overlay. Typically the overlay imposes lower height limits, massing controls or step‑backs to ensure new construction is in proportion with existing historic buildings or sensitive landscapes.

Building Placement

Build-to (Primary)The overlay may adjust setbacks, build‑to lines and lot coverage to reflect existing patterns. For example, deeper front setbacks might be required to preserve a tree canopy, or build‑to requirements might be used to maintain a consistent street wall.

Design Standards

Transparency (Primary)Design guidelines specify materials, architectural details, roof forms and façade treatments that complement the established character. The overlay may require review by a design review board or planning staff to ensure compliance. Additional standards can address signage, lighting and landscaping.

Permitted Uses

Permitted uses generally mirror those of the underlying base district, but certain uses may be prohibited or limited to preserve neighborhood character or environmental quality. For example, automotive uses might be disallowed in a historic residential overlay.

Typical Application

Overlay districts are applied through a rezoning process initiated by residents, property owners or the city. They are commonly used to protect historic residential neighborhoods, unique commercial corridors or natural areas. Examples include preserving mid‑century modern suburbs, protecting the character of a bungalow district, or safeguarding a wetland habitat.
