Creeks - Arroyo Viejo Creek Restoration Complete!
| Arroyo Viejo Creek Restoration Project |
| COMPLETED, January 2002 |
760 tons of concrete was removed from the creek banks and bed and crushed for reuse by Aman Environmental, a debris-recycling company. The decaying concrete walls were replaced using a variety of bio-engineering techniques. For example, trunks from non-native trees removed from the site were used to secure the creek banks in several areas. Brush layering and willow staking were also used. A dilapidated, unsafe, concrete amphitheatre was replaced with terraced pervious seating and a stage area, made from decomposed granite, sculpted into the grade of the creek bank. Replacement of the old amphitheatre allowed room to broaden the creek channel which in turn helped to increase flood capacity, visibility and enhance safety, while providing a new performance space for community theatre, music and dance performances. The 4,500 cubic yards of soil removed from the banks to broaden the channel were donated to the Hayward Area Regional Park District to be used in a wetlands restoration project. A few finishing touches will be completed during the next few months these include fencing around newly planted areas, installation of garbage and recycling receptacles and BBQs at the picnic areas near the creek. There will be a watershed festival and celebration of the completion of the project on Earth Day, Saturday, April 20, 2002 from 11:00 a.m. to 2:00 p.m. at Arroyo Viejo Park.
