After months of staging construction equipment on a piece of land just south of Petaluma for the Highway 101 widening project, San Rafael contractor Ghilotti Brothers, Inc. has found itself in hot water with the County of Sonoma for the possible destruction of wetlands.
"Based on a county permit department review, we've found that it's highly probable that wetlands have been filled in," said Sonoma County Planner Misti Harris. "We looked at aerial shots of the property, checked the soil and visited the site. We found clear signs of wetlands, but we don't have an estimate on how much has been destroyed. That's what we need to figure out before we can approve the project and require mitigations."
The 5-acre construction site in question is located at the southeast tip of a 277-acre plot of land owned by the Dry Creek Band of Pomo Indians. According to the county, the undeveloped site has been home to large Ghilotti Brothers trucks and equipment since November 2012 — despite the fact that the construction company didn't apply for construction permits until April 2013. Without explaining why they didn't pull permits, Ghilotti cited an environmental study that found the site contained no wetlands, but the county disagreed.
Caltrans regularly contracts with firms like Ghilotti Brothers, to manage local infrastructure project sites, like the one south of town for the Highway 101 widening. Jeremy Schofield, Ghilotti Brothers' spokesman, said that the company hired Sacramento-based environmental firm Environmental Services Associates (ESA) to conduct a wetlands study, which concluded there were none located on the site. After studying the land, ESA concluded that although the land supported some wetland vegetation, it was not a wetland site.
According to the U.S. Environmental Protection Agency, wetlands — which include swamps, marshes and bogs — vary widely because of differences in soils, topography, climate, vegetation and other environmental factors. Wetlands feed downstream waters, trap floodwaters, recharge groundwater supplies, remove pollution and provide fish and wildlife habitat. They are often found along waterways and in floodplains.
"We're stuck between two different entities: the county and ESA," said Schofield. "The county says one thing, ESA says another. And all the ESA documentation we've seen suggests it's not a wetlands."
But Harris said that the county has seen clear wetland indicators for quite some time at this particular site, and originally asked the tribe to submit a wetlands study prior to any work being done on the land. Compounding the problem, Harris said, is that Ghilotti Brothers didn't go through the proper permitting process before filling in portions of the land.
"We're playing catch-up here," said Harris. "It's a challenge to do this when work has already started. We're trying to figure out what the original project was, how long it's going to take and what sort of environmental mitigations it would require. Normally, we figure out all that before a project has begun, so that we can ask for things like wetlands protections. Ultimately, if wetlands are found on the land, we won't even know how much they filled in and how much they should mitigate. It's tough."
Allyn Amsk, public information officer for Caltrans, said that while the state transportation entity allows contractors to use private properties for construction projects, it had no idea that Ghilotti Brothers was planning to use this particular site for a Highway 101 project staging area until February 2013 — three months after the site opened.
