Caltrans prepares to shift Highway 1 at Gleason Beach

GLEASON BEACH — Spurred by the rapidly retreating coastline north of Bodega Bay, Caltrans is laying plans to reconstruct a nearly mile-long stretch of Highway 1, moving the roadway safely inland from the crumbling edge of the continent and raising it beyond the reach of the rising sea.

Environmental review of the estimated $20 million realignment project is just beginning, so work crews aren't expected to break ground until at least 2017, project manager Lilian Acorda said.

Caltrans hasn't even negotiated the purchase of needed property yet, including a large portion of an historic ranch across the road from Gleason Beach. The ranchland will be irrevocably altered by a concrete bridge about 400 feet east of the existing road and spanning as much as 900 feet across the parcel.

The project's effect on the landmark property is one in a series of cultural, environmental and biological impacts still to be assessed and addressed during the coming years, Caltrans personnel said. There are seasonal wetlands, a creek that once hosted migrating salmon, red-legged frogs, an endangered butterfly and other wildlife to worry about.

"It's a huge balancing act," said Chris Caputo, an archaeologist and environmental planner for the transportation agency. "There are a huge number of resources out there."

Caltrans is nonetheless in a race with natural forces that have chipped away at the cliffs near Gleason Beach sufficiently to destroy or undercut 10 bluff-top homes and come within a few feet of the fog line at the edge of the highway.

Studies prepared for the project conclude that an 87-foot section of the roadway abutting the bluffs could be undermined within five years, Caltrans said.

A rusting metal fence at the edge of the road already marks one spot where a narrow lip of concrete is all that remains of what was once a home.

A sheer drop below leads down to the ocean, where the waves crash against a tumble of concrete slabs, huge pillars and twisted steel once used to try to stabilize the hillside and the house that was built on it.

The Caltrans project has been in the works for years, outlined some time after the first of several homes began to buckle and break apart following heavy rains in 1998. The downpour ate away at the cliff side, and wave action and drainage have continued their work, causing additional damage and coastal recession.
