LOCATION AND DESCRIPTION:
The Dredge Material Management Framework (DMMF) includes the LA River Estuary (Long Beach - LB), Port of LB, Port of LA, and Marina del Rey, located within the coastal waters of LA Co. All four areas need removal and disposal of contaminated dredged sediments. The Ports of LA; LB; City of LB and LA Co (Marina del Rey) could generate a total of 2.5M cubic yards of contaminated dredged sediment over the next five years. The project creates regional strategy with regulatory coordination for removing the majority of sediments, managing the disposal of contaminated sediments from multiple projects and identifying a multi-user disposal site for receipt of these sediments. Failure to dredge contaminated material may result in economic hardship for the ports, the marina and the City of LB. This study ends upon the completion of the Dredge Material Management Framework document.
AUTHORIZATION: WRDA 92, Sec 204 (as amend by WRDA 96, Sec 207)
ACTIVITES IN FY 2023: Final Report completed and close-out study underway.
FY 2024 PLANNED ACCOMPLISHMENTS: None
ISSUES AND OTHER INFORMATION: Contaminated sediments in Marina del Rey, the Los Angeles River Estuary, and the Ports of Los Angeles and Long Beach must be removed to ensure navigational safety and to provide for port expansion. Permanent disposal sites are not available, and the continued buildup of contaminated sediments raises concerns of potential impact on public health as well as the health of the marine environment. Safe navigation within small craft harbors can be jeopardized by shoaling that cannot be removed and disposed of safely or economically, making the nation's largest and most productive port complex unable to meet increasing demands. The cost increase is due to the regional nature of the study, the intense coordination with the sponsors, and contaminated sediments task force. Additional studies were performed that were not originally foreseen. Although the study name will not be changed, this study is now considered a "Framework" or DMMF rather than a "Plan" or DMMP.
