Alameda County Supervisor Keith Carson, who represents Berkeley, is calling for community input into how to re-draw county district lines.

County officials adjust the boundaries of the supervisorial districts every 10 years after census results are released. Carson represents the Fifth District, which includes Berkeley, Albany, Emeryville, Piedmont, and parts of Oakland.

The population in the district has changed during the past 10 years. Berkeley’s population, for example, went up 9.6% between 2000 and 2010, from 102,734 to 112,580, according to census figures. Carson’s district now has 6,040 people more than the median for the other supervisorial districts.

The deadline for submitting ideas for new district lines to the Alameda County Community Development Agency is June 10. Carson will be holding a meeting Monday June 6, from 6 pm to 8 pm, at the Northbrae Community Church at 1941 The Alameda. He is seeing input into some proposed changes to the county district lines.

Dan Marks, Berkeley’s planning director, will also talk about proposed development changes in the region.
