The city's Adopt-A-Stream program is looking for 100 volunteers for a cleanup effort at Kapalama Stream and an Adopt-A-Block cleanup, which will include Pua Lane, Kanoa and Banyan streets, and Akepo Lane. Both will be held from 8:30 a.m. to 11 a.m. Saturday.

Adopt-A-Stream volunteers will meet at the Honolulu Community College parking lot next to Kapalama Stream. Adopt-A-Block volunteers will meet at the corner of Kanoa and Banyan streets. For information about volunteer opportunities, go to www.cleanwaterhonolulu.com and click on calendar.
