Proposed Zoning Text Amendment for Chesapeake Bay Preservation Act Updates

The Town of Haymarket needs to update the Town Zoning Ordinance to reflect the appropriate Chesapeake Bay Preservation Act Requirements for plat notations. The Subdivision Section of the Zoning Ordinance needs to be amended as shown in the highlighted text below. The highlighted text additions are plat requirements provided to the Town from our partner at DEQ who recently completed an audit of the Town documents and found this deficiency to meet the required standards.

Items for the Town’s consideration:
