Castro Valley Creek Uncovered

175x130 image
Creeks banks have been engineered to return to a natural state.

What was previously a vacant lot covered in asphalt is now a flowing creek with native habitat. When the new Castro Valley Library opens, visitors will enjoy views of Castro Valley Creek brought back to its original, natural state.

The District uncovered almost 300 feet of the creek as it runs along the library east of Norbridge Avenue and planted hundreds of trees and shrubs—27 different native plant species. There are large boulders for sitting and enjoying the view, and a stone amphitheater.

When the new native plantings take
hold, they will create natural habitat
and amentities for visitors.
The restored creek features natural flood protection, called bioengineering, that uses plants and other natural materials, rather than concrete and steel, to reinforce and stabilize creek banks. Native plants and natural materials, such as tree stumps and rock, can lower construction costs. However, maintenance costs are usually higher because living materials require trimming and other care.

The restored creek will actually help reduce the urban heat island by providing tree shade and the natural air conditioning of creeks, as well as reducing carbon dioxide in the air.

Plans call for an additional 900 feet to be enhanced up to Castro Valley Boulevard, with more native plants, pedestrian bridge, lighting, more seating, interpretive panels, sculptural fencing and a 5,000 sq.ft. play area for children. A featured item will be two rain gardens, specialized gardens that capture the urban rainwater that runs off from our streets and is often polluted. The water is filtered through vegetation and the soil, and returned as clean water to the creek.
