Who We Are

Who We Are

Harbor Community Benefit Foundation (HCBF) is a unique non-profit organization that was established in 2011 to respond to community concern about the cumulative environmental exposures in the harbor area – including increased air emissions, water pollution, traffic safety issues, noise impacts, land-use challenges, and general quality-of-life concerns. As an independent 501(c)(3) nonprofit organization, HCBF manages and exclusively administers the Port Community Mitigation Trust Fund (PCMTF) in the original amount of $9.8 million.

HCBF also exclusively administers the Air Quality Mitigation Fund, which originally had $5 million for the demonstration and implementation of emission reduction technologies to reduce air emissions in the San Pedro Bay area. 

Harbor Community Benefit Foundation(HCBF) supports the communities adjacent to the Ports of Los Angeles and Long Beach through research, education, and grant funding. HCBF Staff and its seven-member volunteer Board work with local partners and expert consultants to address critical needs of the community, as well as assess land use and noise impacts from goods movement in the area to inform our work in grantmaking and ensuring community benefits.

The most important aspects of HCBF’s work include:

  • Administering funds to community organizations to address port-related impacts.
  • Making a positive difference in quality of life through research, grant making, and service to community organizations and other partners.
  • Being a trusted steward of community funds to address the cumulative impacts faced by
    port-adjacent communities.
  • Reflecting community knowledge of disparities and supporting their initiatives and
    solutions to the problem.

Harbor Community Benefit Foundation invests in the quality of life for communities impacted by port-serving industries.
