. '. PROJECT NAME : \' Invasive Spartina Project: Spartina Control Program Addendum" (Addendum), attached as . Exhibit 5, describes the incorporation ofimazapyr as a treatment tool and its anticipated impacts. The Addendum and the fmdings proposed for its approval under CEQA are also discussed in detail below, under the heading "Compliance with CEQA". The strategy for eradication of invasive Spartina described in detail in the March 10, 2005 Staff Recommendation guides the Site-SpeCific Plans and is designed to achieve the following objectives for the 200572006 treatment. p:oj~ts: (1) f?llo~ up on control work th.at.,,:,as previously completed; (2) treat the remammg infested SItes 10 the Estuary; and (3) mmUnIze . potential adverse aff~ctS on the end~ger~ Calif~rnia cl~pper rail and other li.st~ species. Among the infonnatlon about each SIte 10 the SIte-SpeCIfic Plans are a. descnptIon of the htlestation, method for removal, an evaluation. of impacts, and the mitigation measures the grantees are required to implement. Below is a brief summary of the sixteen projects proposed . for Conservancy funding, followed by a summary of the six ~dditional projects to be funded by other sources. 'Grants for 2005/2006 Treatment Proiects: 1. Alameda Flood Control Channel. Alameda County (Grantees: Alameda Flood Control District and the California Wi~dlife FOtpldation) . . The Alameda Flood Control Channel site includes the entire tidal reach of the Alameda Creek Flood Control Channel (a.k.a., '1he Federal Project" or "Coyote Hills Slough'), as well as the Pond 3 restoration site (the initial introduction place for S. alterniflora in the Bay). and a strip of diked marsh to the north of the channel. The total site includes 471 acres of tidal marsh, with 149 acres of non-native Spartina, all of which Will be treated during the 2005 and 2006 control seasons. Treatment methods at the site will include .application of aquatic' herbicide via spray truck, amphibious tracked' vehicles, and helicopter. Potentially significant, unavoidable short-term impacts to visual resources and the endangered salt marsh harvest mouse were identified at some sub-sites. 2. . Alameda/San Leandro Bav Complex. Alameda County (Grantees: East Bay Regional Parks District, City of Alameda, Alameda . County Flood Control District, . California . Wildlife Foundation) The Alameda/San Leandro Bay Complex includes the entire shoreline of Alameda Island, and all of the marshes and tidal channels surrounding San Leandro Bay. The total site includes 314 acres of tidal marsh and channel, with 89 acres of non-native Spartina. To . minimize impacts to highly sensitive California clapper rail habitat and to allow time for public education, control work in this complex will be phased over a number of years, with 37 acres slated for treatment in .2005 and up to 100 estimated acres in 2006. Treatment methods at the site will include application of aquatic herbicide via spray 'truck, backpack sprayer, amphibious tracked vehicles, boat, and helicopter. Potentially significant, unavoidable short-term impacts to the endangered California clapper rail were identified at some sub-sites. . 3. Bair and Greco Islands Complex, San Mateo County (Grantee: USFWS Don Edwards National Wildlife Refuge) The Bair and Greco Islands Complex is comprised of 10 sub sites that encompass the entirety ofBair and Greco island tidal marshes and the sloughs and creeks connecting and - .... - ....
