DEPARTMENT OF THE ARMYSAN FRANCISCO DISTRICT. CORPS OF ENGINEERS 211 MAIN STREETSAN FRANCISCO. CALIFORNIA 94105 SPNED-E/SPNCO-R SUPPLEMENTAL INFORMATION REPORT TO THEPORT SONOMA FINAL ENVIRONMENTAL STATEMENT TO WHOM IT CONCERNS: 1. The attached Supplemental Information Report provides additional information concerning the Environmental Statement (ES) for the Port Sonoma Marina Development, (Permit No. 75-212-039), which was distri­buted in February 1977, by the San Francisco District of the Corps of Engineers. 2. This Supplemental Information Report has been prepared to address the issue of potential growth-inducement of a related permit applica­tion by Shellmaker, Incorporated. Shellmaker proposes to install a 2 1/2-inch private water supply pipeline under the Petaluma River (PN 12548-39) and connect it with an existing 1 1/2-inch meter on the Marin County (south) side of the river, which is serviced by the North Marin Municipal Water District (NMMWD). This water pipeline would supply water to the Port Sonoma Marina Development. The issue of potential growth-inducement was not discussed in the Port Sonoma ES, since at the time of ES preparation the applicant, (Shellmaker, Inc.), indicated that no external water or sewage utility connections would be needed for the development. 1 Inclosure As stated C/JOHN M. ADSIT / Colonel, CE( District EngineerSUPPLEMENTAL INFORMATION REPORT FOR THE FINAL ENVIRONMENTAL STATEMENT, PORT SONOMA DEVELOPMENT, SONOMA COUNTY, CALIFORNIA 1. INTRODUCTIONThis Supplemental Information Report reviews the potential for growth­inducing impacts of a San Francisco District, U.S. Army Corps of Engineers permit application (PN #12548-39) by Shellmaker, Incorporated, to install a private domestic water supply pipeline near Elack Point, in Sonoma County, California. The pipeline would cross beneath the Petaluma River ,the boundary between Marin and Sonoma Counties. This Report supplements the Final Environ­mental Statement (FES) (dated January 1977)

DEPARTMENT OF THE ARMY SAN FRANCISCO DISTRICT, CORPS OF ENGINEERS 211 MAIN STREET SAN FRANCISCO, CALIFORNIA 94105 Environmental Branch FEB 21984 Supplemental Information Report Acme Landfill Expansion Contra Costa County, California January 1984 1. Acme Fill Corporation has applied for a Department of the Army permit to place dredged material and landfilled wastes on 173.7 acres of land adjacent to the existing Acme Landfill located approximately two miles east of Martinez, California, adjacent to Walnut and Pacheco Creeks. Acme Fill Corporation’s current application which was announced in Public Notice No. 13881E59 (Revised) issued December 19, 1983, is a modification of a previous application which was announced in Public Notice No. 13881E59 issued August 13, 1982. In June 1983, the Corps of Engineers circulated a Final Environmental Impact Report/Environmental Inpact Statement (FEIR/EIS) regarding the proposed expansion of Acme Landfill. The FEIR/EIS was prepared in cooperation with the Contra Costa County Planning Department. The purpose of this Supplemental Information Report is to provide interested parties with information regarding changes in the environmental impacts of the proposed project due to Acme Fill Corporation’s modification of its application. The attached Environmental Evaluation describes the modifications to the proposed project in detail and discusses differences between the environmental effects of the current proposed project and those described in the FEIR/EIS. Pursuant to the Corps of Engineers’ Policy and Procedures for Implementing NEPA (National Environmental Policy Act) (33 CFR 230), this Supplemental Information Report is being filed with the Environmental Protection Agency and circulated to concerned agencies and the interested public who provided comments on the Draft or Final EIR/EIS. 2. As announced in Public Notice No. 13831E59 (Revised), the Corps of Engineers will conduct a public hearing on Acme Fill Corporation’s application

DRAFT FEASIBILITY STUDY AND ENVIRONMENTAL IMPACT STATEMENT OAKLAND INNER HARBOR CALIFORNIA DEEP-DRAFT NAVIGATION AUG 02 1983 %'SCH\U>£> United States Army Corps of Engineers ...Serving the Army ...Serving the Nation San Francisco District JULY 1983 DEPARTMENT OF THE ARMY SAN FRANCISCO DISTRICT, CORPS OF ENGINEERS 211 MAIN STREET SAN FRANCISCO, CALIFORNIA 94105 OAKLAND INNER HARBOR ALAMEDA COUNTY, CALIFORNIA DEEP DRAFT NAVIGATION IMPROVEMENTS DRAFT FEASIBILITY STUDY ENVIRONMENTAL IMPACT STATEMENT SYLLABUS The purpose of this study is to investigate navigation conditions at Oakland Inner Harbor and to determine whether the provision for improvement of existing deep-draft channels is advisable. Oakland Inner Harbor Channel provides deep-draft access for the Port of Oakland. It was found that the growth of foreign and coastwise shipments and the introduction of larger vessels in the World Pacific Basin Fleet have rendered the existing Federal project channel and turning basin inadequate and inefficient for modern transportation needs. Traveling and maneuvering of the vessels are restricted and the channel is too shallow for larger containerships which must await high tide to navigate the channel. Various solutions to the navigation problems in the Oakland Inner Harbor Channel were analyzed. The most practicable and feasible plan consists of deepening the existing Oakland Inner Harbor Channels, from -35 feet, mean lower low water (MLLWj, to -43 feet, MLLW, and widening the channel at a number of places to permit optimum utility of restricted channel dimensions. The estimated total cost of the selected plan is $27.1 million. Using a 7-7/8 percent discount rate and 50-year period of economic evaluation, the annual charges would be $2.2 million, and the annual project benefits are $34.9 million. Therefore, the benefit/cost ratio would be 15.9 to 1. It Is recommended that the foregoing plan of improvement be adopted as a modification of the existing Federal project for Oakla
