Based in Walnut Creek, California, RMC Water and Environment brings extensive expertise to water-related projects across the state. As champions of environmental stewardship, employees of RMC Water and Environment proudly work with many local and regional sustainability projects, including restoration efforts at Sibley Volcanic Regional Preserve.
A team from the Walnut Creek office spent an afternoon helping to remove invasive species and restore grassland at Sibley, an Oakland park set atop a peak made up of volcanic debris and lava. Ten million years ago, a volcano erupted, creating the materials that would later become Sibley Preserve. Today, the area is open to visitors for hiking and nature exploration.
Brochures at the unstaffed visitor center offer self-guided tours and information about unique geological features of the area. A number of trails let hikers and walkers of all levels explore the beautiful and rich natural environment. The park is open year-round.
