​Historic Design Zoning Overlay

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.     

Maps of the (-DH) Combining Zone boundaries for the historic townsites of Clarksburg, El Dorado and Diamond Springs can be found in the El Dorado County GIS Map Library.  See GIS map numbers G10073614A (Diamond Springs), G10073614B (El Dorado) and G10073614C (Clarksville).  

For regulations and procedures for development within a (-DH) Combining Zone, please refer to Title 130, Section 130.27.060 (Design Review-Historic [-DH] Combining Zone) in Article 2 (Zones, Allowed Uses and Zoning Standards) and Section 130.52.030 (Design Review Permit) in Article 5 (Planning Permit Processing) of the County's Zoning Ordinance.

On December 15, 2015, the Board adopted a Targeted General Plan Amendment (Resolution No. 196-2015) which included revisions to Policy 2.4.1.3 requiring all properties located within the historic townsites of Clarksville, El Dorado and Diamond Springs be designated on the zoning maps as a Design Historic (-DH)  Combining Zone District (Legistar File No. 11-0356, Attachment No. 28, pg. 11).  The Board also adopted Ordinance No. 5030, a comprehensive update to Title 130 (Zoning Ordinance),  which included amendments to Section 130.27.060 (Design Review - Historic (-DH) Combining Zone) to update and clarify procedures and regulations for future development within the (-DH) Combining Zone District (Legistar File No. 11-0356, Attachment No. 35).
