Chestertown Mayor David Foster is continuing his lobbying for a tax differential or tax rebate. Foster has asserted that town residents are typically required to pay both for their local police and for their county sheriff’s office even though the primary responsibility for the sheriff’s office is for residents living outside of town. Foster has announced two “special public meetings” to discuss the issue: Thursday, Jan. 30 at 6 p.m. at Chestertown Town Hall, 118 N. Cross St., and Tuesday, Feb. 11 at 2 p.m. with the Kent County Commissioners at the R. Clayton Mitchell Jr. Kent County Government Center, 400 High St.
