NOTE: Plans submitted not using the County’s redistricting software may take longer than three business days, but no more than ten business days, depending on submitted content.
  • Proposers may resubmit plans that have been revised as a result of a County analysis. However, resubmittals are subject to the June 2, 2011 deadline. Therefore, any original submissions must be received in sufficient time to allow for review, revision, and resubmission. Any initial plans submitted after May 30, 2011 may not be analyzed nor returned for resubmission because of time constraints.
