To protect historic structures and sites, the Zoning Ordinance establishes additional design regulations for land use and development within designated historic districts, identified by the Design Review – Historic (-DH) Combining Zone. Properties within the (-DH) Combining Zone include the historic townsites of Clarksville, El Dorado and Diamond Springs. Property owners within other historic townsites may request to be included within the (-DH) Combining Zone consistent with the requirements of Section 130.63.020 (Ordinance Amendments and Zone Change Applications) of the County's Zoning Ordinance.
