The Planning and Zoning / Development Services Department is managed by Jim Hickey, AICP, establishes and enforces development criteria such as setbacks, building heights, landscaping, and signs, to assure that Weston's unique appearance is preserved. All building plans, whether new construction or the modification of an existing building, require the review and approval of Planning and Zoning prior to the application for a building permit. 

The department also includes a variety of other disciplines, including engineering, traffic engineering, landscape architecture, tree preservation, land surveying, etc.  The Engineering division establishes and enforces infrastructure criteria such as water, sewer, paving, and drainage, and catalogs this infrastructure within the City's Geographic Information System (GIS).
