Giacomini Wetland Restoration Project: Summary of Construction Under Phase I and II
summary of construction under phase I and II includes:
Construction efforts aimed at restoring the former Waldo Giacomini Ranch to wetland were largely complete as of December 2008. However, this does not mean that restoration or construction is entirely complete. Additional construction may occur in future years in the Giacomini Ranch and Olema Marsh should the National Park Service (NPS or Park Service) and Point Reyes National Seashore Association (PRNSA) be able to secure additional funding. These restoration activities include continued restoration of hydraulic connectivity in Olema Marsh and further lowering of high elevation areas in the Giacomini Ranch, as well as continued treatment and retreatment of non-native invasive plant species. In addition, the Park Service continues to seek funding to implement the public access portion of the project.
Restoration, too, is an ongoing process. While the bulldozers and excavators may be gone, the process of restoring these diked and altered systems to fully functional marshes is just beginning and will continue to unfold into the future. Please see our Restoration web page for updates and information on the status of the restoration process.
Construction of the restoration component of the Giacomini Wetland Restoration Project was implemented in two principal phases-Phase I in fall 2007 and Phase II in summer and fall 2008.
Phase I, which spanned from September 2007 through December 2007, principally involved removal of agricultural infrastructure and conditions and creation of special status species habitat.
Phase I included:
The second and largest phase of the project was Phase II, which ran from July 2008 through December 2008. Phase II focused on marshplain and floodplain restoration.
Phase II included:

Graphics showing revegetation and invasives removal efforts can be found in later pages of this section.
Point Reyes National Seashore Association (PRNSA), which acted as the contracts manager, brought on Winzler & Kelly Engineers (Santa Rosa, Calif.) to oversee construction of Phase I and II in the field. PRNSA helped to raise most of the monies for this project and managed the construction portion in collaboration with the Park Service. Argonaut Construction of Santa Rosa, Calif., was the construction contractor for Phase I, while Hanford ARC of Sonoma, California, was the construction contractor for Phase II.

Climate scientists warn that the safe upper limit for atmospheric carbon dioxide (CO2) concentrations is 350 parts per million (ppm). For most of human history, atmospheric CO2 rarely exceeded 275 ppm--until the industrial revolution. As of 2014, atmospheric CO2 was ~400 ppm–-and rising 2 ppm/year. More...
