Giacomini Wetland Restoration Project: Draft Environmental Impact Statement / Environmental Impact Report
Since the early 1900s, levees constructed at the southern end of Tomales Bay for roads and dairy farms have served to hydrologically disconnect Lagunitas Creek and its tributaries from their floodplains. As a result, wetland conditions within the Waldo Giacomini Ranch and Olema Marsh (Project Area) have been degraded, and hydrologic and ecological functionality of what was once of the largest integrated tidal marsh complexes in Tomales Bay has been substantially reduced. Natural wetlands provide many important functions for humans and wildlife, including floodwater retention, water quality improvement, wildlife habitat, and recreational opportunities. Because two-thirds of the Bay’s freshwater inflow passes through the Project Area, these wetlands may have once played an integral role in maintaining health of Tomales Bay, which has deteriorated over the last century because of excessive sedimentation, water and sediment quality problems, non-native species invasions, and other issues.
In 2000, the National Park Service acquired the Waldo Giacomini Ranch for the purpose of wetland restoration using a combination of Congressional appropriations and mitigation monies from the California Department of Transportation. Because the Project Area is in the northern district of the Golden Gate National Recreation Area, it is managed by Point Reyes National Seashore.
This Draft Environmental Impact Statement/Environmental Impact Report (DEIS/EIR) evaluates four alternatives for restoring wetlands and wetland functionality and incorporating public access opportunities that do not impact wetland function, as well as the No Action Alternative (e.g. closure of the dairy and discontinuation of intensive agricultural management). The primary purpose and objectives of the proposed project include: restoring hydrologic and ecological processes and functions in a significant portion of the Project Area; emphasizing actions that would benefit the health of the entire Tomales Bay watershed and not just the Project Area; and incorporating opportunities for experiencing and enjoying the restored wetlands that do not conflict with the project’s purpose. Alternative C is the lead agencies’ preferred alternative, because it best meets the purpose of restoring wetlands while also providing opportunities for public access that answer some of the local community’s needs. Alternative D would be the environmentally preferred alternative, because it provides the most restoration, although it also incorporates the least public access opportunities relative to the other action alternatives.
The National Park Service and the California State Lands Commission will accept comments on the DEIS/EIR from the public for 60 days from the day on which the Environmental Protection Agency publishes the Notice of Availability in the Federal Register. Our practice is to make comments available for public review. If you wish to have your name, address, phone number, or email address withheld from the public, please request this prominently at the beginning of your comments. Please include a rationale for your personal information being withheld from public review that demonstrates disclosure would constitute a clearly unwarranted invasion of privacy. Unsupported assertions will not meet this burden. In the absence of exceptional, documentable circumstances, this information will be released. Submissions from organizations or businesses, and from individuals identifying themselves as representatives or officials of organizations or businesses, will always be made available for public review in their entirety.

Marine biologists have identified nearly a third of all known marine mammal species in the waters surrounding Point Reyes. Blue whales and humpback whales feed here during spring and summer months. Gray whales migrate past our shores twice a year on their round trip from Alaska to Baja. More...
