Sonoma County community service coordinators are seeking volunteers for the Jan. 25 street count of local homeless people.

The annual point-in-time survey is a critical measure of shifting homeless populations and demographics and is a requirement of eligibility for certain federal Housing and Urban Development shelter and housing funds.

It requires people to count homeless people in shelters, jail or other institutions on the eve of the principal survey, when teams fan out across the county to log each person sleeping along creek trails, in cars and encampments, or wherever people may be found, roughly between 5 a.m. and 10 a.m.

Volunteers also participate in a 1-hour training on Jan. 16 or 17.

Go to www.surveymonkey.com/r/2019SonomaPIT to sign up.
