I don’t think Horned Grebe has ever been noted breeding anywhere in California. They are expected in the Bay November through April.
Also, for sightings in San Francisco please use SFBIRDS @groups.io
EBB is for Alameda and Contra Costa.

On 4/16 looked for Rock Sandpiper at Heron Head Park . No luck. But saw a Horned Grebe in full breeding plumage, mainly on north side of the break. Do they breed here?
