(PressDemocrat) - Winemaker Paul Hobbs has been ordered to stop work on his controversial orchard-to-vineyard conversion near Sebastopol after inspectors found that hundreds of yards of blackberry bushes and bay laurel had been cleared illegally from a protected zone above a creek.

“It's a very serious violation of their permit,” said Sonoma County Agricultural Commissioner Tony Linegar, whose office issued the stop work order to the Paul Hobbs Winery.

Rules prohibiting the removal of riparian growth from within 50 feet of a waterway are a “cornerstone of our erosion control plan,” he said.

Hobbs has had several high-profile run-ins in recent years with county officials and neighbors over his land-clearing practices. On Friday said he had been in Asia when the clearing took place.

“I've got to say, I'm baffled and I'm very sad to see this situation. I feel bad for putting the county through this,” he said. “I'm taking full responsibility for this and I'm going to make the changes I need to make to fix it.”

 The order, issued on Tuesday, also cited a failure to install proper erosion control measures, which allowed sediment to flow into the creek during recent rains.
