The article elides past some distinctions that are worth noting. First, school funding in California is based on attendance (the so-called "ADA," or average daily attendance), not enrollment (ADA is usually about 90% of enrollment, although there is a lot of variation). Paying attention to the attendance figure will be the more reliable indicator of the state of school finance going forward in Sonoma County.
Second, and related to the first point, is that as of November 2022, 16 of the 40 school districts in Sonoma County were "basic aid" districts, whose revenues do not change with either attendance or enrollment. In 2021‑22, the state had 118 basic aid school districts (about 13 percent of all districts). As attendance continues to drop, more and more Sonoma County districts will become basic aid. Basic aid will increasingly be the default rule in Sonoma County. These districts (like Sonoma Valley) will ironically end up with more money per student given declining attendance, which is why many of these districts may very well not be interested in district consolidation intended to cut costs, as such consolidation would in fact reduce per-student funding. There are a number of these districts in San Mateo, Santa Clara, and Marin counties, those counties having had many of the same housing issues as Sonoma County for a longer period of time, and the trend in those counties has generally been against consolidation of districts.
A final point, which comes up here from time to time. "Affordable Housing" is a term of art in many respects, and while there is a shortage of housing that can be afforded in Sonoma County by most people, that is different from "Affordable Housing." Sonoma County just lacks housing, period. Narrowing the issue using the term of art is probably not the most helpful, because it obscures the fact that the response to the crisis needs to be comprehensive.
