The Missouri Flat Design Guidelines for commercial development were adopted by the Board of Supervisors on June 3, 2008, by Resolution 134-2008 (Legistar File 08-0754).  On April 24, 2018, the Board of Supervisors adopted an updated version dated May 2017 by Resolution 074-2018 (Legistar File 18-0542).  

The following revisions were made as a result of recommendations by the Diamond Springs/El Dorado Community Advisory Committee:

  • Section 2.3 "Mountain Architecture" (original pages 2.4 and 2.5) was removed as this style is not consistent with other architectural styles in the Design Guidelines.
  • A photograph that was on page 3.34 of the previous version (renumbered to page 47) with the caption "Building entries should be emphasized with architectural details" was replaced with an image of a more typical retail building entry, as the previous image was deemed not representative of architectural styles in the Design Guidelines.

The purpose of these guidelines is to improve the quality and character of the built environment and create a more pedestrian-friendly atmosphere with enhanced public spaces along the corridor. The Guidelines will be applied to all non-residential development within the corridor, from El Dorado Road to Pleasant Valley Road.
