Public Notices

A public notice is the primary method for advising all interested parties of a proposed activity for which a permit is sought. Soliciting comments and information necessary to evaluate the probable impacts on the public interest. Public notices are also published to inform the public about new or proposed regulations, policies, guidance or permit procedures.  

Public Notices published by the Los Angeles District are posted on these three pages. There are two types of Public Notices; Regulatory and Project Public Notices. Comments are due by the expiration date of the public notice. 

Only comments submitted by email or in hard copy format through a delivery service, such as the U.S. Postal Service, can be accepted.   Comments must be submitted to the address listed in the public notice.

SPL-2012-00817 OCPW Countywide Long-Term Maintenance Program

USACE Regulatory
Published June 25, 2025
Expiration date: 7/25/2025

OCPW has applied for a Regional General Permit (RGP) to conduct routine maintenance activities throughout the facilities identified in Exhibits 1 and 2 on an as-needed basis. Types of maintenance activities that would be covered under the permit are listed in Exhibit 3. The permit would primarily authorize temporary impacts to waters of the U.S. but would also authorize permanent impacts for some activity types (e.g., riprap installation). The proposed maintenance activities would be expected to result in no more than minimal impacts to the aquatic environment, based on the existing conditions of the facilities and/or the lack of environmental resources. The purpose of the proposed Maintenance Program would be to maintain the functional capacity of facilities, minimize the risk of damage, reduce flooding and erosion of adjacent roadways and properties during storm events, perform bridge maintenance, maintain the County’s long-term mitigation sites, and implement channel improvements deviating from as-built conditions when environmental benefits result from the new design.
