The Crestwood Board of Aldermen may vote tonight on a new zoning code for the city, marking the end of an undertaking that has been years in the making. The Board of Aldermen is slated to hold a second reading on the new zoning ordinance when it meets by videoconferencing at 7 p.m. Tuesday, Dec. 22. The revamped zoning code has been an ongoing project between the city and planning firm Peckham Guyton Albers and Viets since 2018. The Planning and Zoning Commission began reviewing the draft ordinance from PGAV in July 2019, beginning with the sign code, which was formally adopted by the Board of Aldermen in January this year.
