What’s behind Discovery Bay’s civic life grade
Discovery Bay isn’t graded on civic life: it’s unincorporated, so its nonprofits can’t be counted reliably (mailing addresses don’t follow its boundary) and it has no public library of its own.
Civic life counts registered nonprofits, library visits and online volunteering groups, so it can miss civic life that runs through congregations, mutual aid or neighbors looking out for each other.
