What is form-based zoning, and how is it being used in the Oak Cliff Gateway plan? Those questions will be answered in a meeting at 7 tonight, Nov. 16, at Turner House.

The Old Oak Cliff Conservation League and the Dallas Homeowners League invited two experts, Virginia McAlester and Peer Chacko, to explain form-based zoning to neighbors.

McAlester is an author, preservationist and form-based zoning advocate. She will explain the history of form-based zoning, its cost effectiveness and usefulness in fostering community.

Peer Chacko is assistant director of the city’s Development Services department. He will explain and answer questions about the more technical aspects of form-based zoning.

The seminar is free and open to the public.
