CENTRALSAN jdf A- hom CENTRAL CONTRA COSTA SANITARY DISTRICT October 14, 2020 TO: HONORABLE BOARD OF DIRECTORS FROM: NATIONAL DEMOGRAPHICS CORPORATION REVIEWED BY: KENTON L. ALM, ESQ., DISTRICT COUNSEL ROGER S. BAILEY, GENERAL MANAGER SUBJECT: HOLD PUBLIC HEARING TO RECEIVE INPUT FROM THE COMMUNITY REGARDING DRAFT BOUNDARY MAPS AND COMPOSITION OF DIVISIONS TO BE ESTABLISHED FOR DIVISION-BASED ELECTIONS PURSUANT TO ELECTIONS CODE SECTION 10010 Attached is the presentation to be given by Central San's demographer at the meeting. Since the last public hearing, the demographer has developed five draft maps, all of which are attached. Each file consists of two pages -the first is the map, the second is the demographic profile of the proposed election divisions. Also, an interactive review map is available on Central San's website at: centralsan.org/pod/proposed-maps. This map allows residents to review the draft maps in detail (including being able to zoom in, zoom out, change to a satellite view base map, and search for a specific address); however, this review map does not enable anyone to draw or change a map.
