Destination Retail: Retail businesses that generate a special purpose trip and that do not
necessarily benefit from a high-volume pedestrian location.

Detention Basin: A facility that holds storm water temporarily and allows it to drain slowly
over time to ensure that downstream storm drain capacities are not exceeded.

Developable Acres, Net: The portion of a site that can be used for density calculations. Some
communities calculate density based on gross acreage. Public or private road rights-of-way
are not included in the net developable acreage of a site.

Developable Land: Land that is suitable as a location for structures and that can be
developed free of hazards to, and without disruption of, or significant impact on, natural

exchange for certain concessions by the owner.
