A Long Beach-based project engineering firm, ALTA Environmental, has opened an office in Oceanside.

It’s the company’s second office in San Diego County, a region in which it has operated for more than six years.

The new office will serve clients in the North County area, the company said Thursday in a statement.

ALTA Environmental said the new office, at 2110 S. Coast Highway, Suite B, was needed to handle its growing portfolio.
