The Department of Water Resources (DWR) has announced that the initial basin boundary modification request submission period is now open through March 31, 2016. This is the first basin boundary modification request submission period. Future submission periods will correlate with updates to Bulletin 118 in years ending with 0 or 5, with 2019 being the next identified submission period for the 2020 Bulletin 118 update. There may be an additional submission period in 2018 based upon demand from local agencies. Only local agencies are eligible to request basin boundary modifications, but the process is open to the public for review and comment.
DWR has established a series of supporting documents to guide users through the process which can be accessed here.
If seeking a boundary modification, each local agency is required to submit to DWR an Initial Notification to advertise their exploration of the modification prior to submission of the basin boundary modification request. All initial notifications and basin boundary modification requests can be reviewed in the Basin Boundary Modification Request System (BBMRS), which can be accessed here. Once a request is submitted, reviewed, and deemed by DWR to be complete, a 30-day public input period is opened. Public input can be submitted to each specific request using the BBMRS system. Technical reviews will not be made by the department until the 30-day public input period concludes and local agencies have provided any additional information in response to the public input.
