Up to 7,500 people are expected at the 5th Annual Sustainable Ballard Festival this weekend at Ballard Commons Park on 22nd Ave. The free event is focused on teaching the community about living and enjoying sustainable lifestyles. This year’s festival will be modeled after an old-time county fair with games, contests and music. Some of the activities include the “Eat Local Challenge” and how to raise chickens in the city. If ready, Sustainable Ballard will also be showing off the prototype of the hygiene station for the proposed car camps, which has sparked quite the discussion on MyBallard. The free event runs from 11 a.m. to 5 p.m. on Saturday and Sunday.
