Tuesday was the presentation day for senior projects at Sonoma Valley High School. After working most of the school year on their projects, the seniors had to explain them to a group of judges. Tabatha Griewe takes the top off a house she made as part of her project on interior design. Two-hundred-ninety community members signed up to be judges. Judging panels judged four projects each from 5 to 7 p.m. Tuesday as the event occupied most of the classrooms on the Sonoma Valley High School campus.
