Mission & Focus Areas
The foundation’s mission is “to inspire and strengthen charitable giving that enriches the quality of life in our vibrant CBF communities.” Its 2025 filing describes grants to qualified tax-exempt nonprofits for work directly benefiting Columbia Basin residents, prioritizing projects that build community, strengthen community connections, and benefit a broad segment of the local population. The filing also reports that 143 scholarships were awarded in 2025, with recipients selected based on merit, school participation, grade point average, and/or need.
The foundation’s grant materials list youth programs, women and children in crisis, environmental projects, community projects, and animal shelters as areas of interest. Its website also describes unrestricted, designated, donor-advised, field-of-interest, scholarship, and agency endowment funds.
