FINALENVIRONMENTAL STATEMENT MAINTENANCE DREDGING,PETALUMA RIVERSONOMA AND MARIN COUNTIES, CALIFORNIA August 1975 Prepared byU.S. Army Engineer District, San Francisco, Corps of EngineersSTATEMENT OF FINDINGS MAINTENANCE DREDGING, PETALUMA RIVER SONOMA AND MARIN COUNTIES, CALIFORNIA 1. I have reviewed and evaluated, in light of the overall public interest, the documents concerning the proposed action, as well as the stated views of other interested agencies and concerned public, relative to the various practicable alternatives in accomplishing the program for maintenance dredging in Petaluma River. 2. The possible consequences of the Petaluma River maintenance dredg­ing have been studied according to environmental, social well-being, and economic effects, including regional and national development, and engineering feasibility. 3. In evaluation, the following points were considered pertinent: a. Environment.il Cans iderations (1) Dredging Effects: (a) Dredging the Petaluma River will increase the average depth, hence the capacity of the river channel. This will alter the present flow and sediment transport regimens making the project area susceptible to higher average Salinity and increased shoaling rates upstream. The project may alstj cause the existing salt water wedge to intrude further upstream of the project .area than it now does. On the other hand, the project will improve the flushing efficiency of the river and provide greater capacity for flood control purposes. Because the upper reach of the project area is already under tidal influence, the biological response to these physical changes 'would be minimal. (b) As with nearly any dredging project the subject dredging will remove the existing interface between the water and bottom substrate which is an area of nigh biological activity. Benthic organ­isms inhabiting the sediment column to the two-foot overdepth dredged level would not only be destroyed in themselves, but also lest relative to their function

All of these are temporary in nature and are minor when one considers the long-range overall enhancement of social and economic productivity of the harbor area by the assurance of continued harbor access. The maintenance will preserve the harbor for use as a commercial and recreational fishing port as well as a harbor of refuge. c. Engineering Considerations. The dredging operation will be accomplished by using a hydraulic dredge. This method employs a floating platform with a cutter head and suction pipe which extends into the wTater through which material is loosened and vacuumed up to a system wThich pumps the slurry (water and sediment) through a transfer pipeline to the disposal site. The pipeline is placed on the river's bank or floated on the surface of the water to the disposal site. The material dredged could be deposited on a five acre land disposal area approximately one mile upstream of the project. Should the contractor choose, he has the option of supplying his own disposal site, different from ttie site provided by the local project sponsor. He must, however, have all necessary clearances and coordination prior to bidding on the job. 4. I find, after a thorough analysis and evaluation of the maintenance dredging of Novo River and Harbor channels versus the option of "no-action", that wherever adverse effects are found to be involved they cannot be avoided by following reasonable alternative courses of action which would achieve the congressionally specified purposes; that where the proposed action has an adverse effect this effect is either ameliorated or substantially outweighed by other considerations of national policy, statutes, and administrative directives; and that, on balance, the total public interest shoul

NAME OF ACTION: (X) ADMINISTRATIVE ( ) LEGISLATIVE 2. DESCRIPTION OF ACTION; The Humboldt Bay Harbor, Recreation and Conservation District proposes to develop the southern shore of Woodley Island and the Eureka Inner Reach Channel. The project that was assessed in the Draft Environmental Statement has been revised5to the project described in this Final Environmental Statement. The revised project would be a 237-berth marina with an access road from Highway 255, parking facilities, support facilities and a potential for limited commercial development. Berthing facilities would extend 120 feet into the Federally maintained channel, leaving 260 feet of it navigable. 3. (a) ENVIRONMENTAL IMPACTS: The proposed project would alter theconfiguration of the Eureka Inner Reach Channel. Subtidal and inter­tidal flats along the southern edge of the Island would be removed, and the existing associated benthic habitat would be altered. Marina con­struction and dredged material disposal would impact existing wildlife habitat values on the southern one fourth of the Island and commit the area to relatively intensive human uses. . There would be an increased, need for maintenance dredging in the area. Building materials and petroleum resources would be irreversibly committed. There would be socio-economic benefits for the Eureka boating community. (b) ADVERSE ENVIRONMENTAL EFFECTS: The proposed project would re­duce the width of the open channel by 120 feet.

A California Environmental Quality Act (CEQA) review will likely be carried out by the Water District as part of the decision making process concerning the lifting of the moratorium.The Water District Board of Directors is now develop­ing a Safe Water Supply Program which would be used as the primary guideline for determining water availa­bility for projects such as the Marin Mall. 25 2.72 This paragraph discusses the Air Quality MaintenancePlan for the San Francisco Bay Area air basin. It should be noted that the U. S. Environmental Protection Agency is now requiring State Implementation Plans (SIP's) by 1 January 1979 which show how National Standards can be attained by December of 1982. For Oxidant and Carbon Monoxide extensions may be granted to 1987 if all reasonable technology has been applied.The 3 March 1978 issue of the Federal Register announced that the Bay Area does now not meet the Primary Standards for Oxidant and Carbon Monoxide and does not meet the Secondary Standard for Total Suspended Particulate.Also, it should be noted that the Federal New Source Review program does not apply because a shopping center is•considered an "indirect source." 47 4.48 Reference is made to "Five different situations. ."which have been considered in Appendix B.

Legislative authorities applicable to this regulatory permit action are Section 10 of the River and Harbor Act of 1899 (33 U.S.C. 403) and Section 404 of the Clean Water Act of 1977, as amended (33 U.S.C. 1344). The structural flood control alternatives evaluated in-depth in this final EIS would involve construction of earthen bypass and overflow channels, and earthen levees along a 6.5 mile stretch of the Creek to provide protection frail major flooding. Implementation of the applicant’s recommended alternative, the "Proposed Project" alternative, would result in displacement of aquatic and wetland habitat, removal of approximately 14 acres of the riparian trees in the project area, adverse effects on fish and wildlife, and impacts to habitat of an endangered species. A mitigation program developed to canpensate for the adverse environmental effects Includes establishment of wetland and upland habitat, planting of 42 acres with riparian species, and protection and long-tem management of endangered species habitat.

This combined Feasibility Report and Environmental Impact Statement complies with the requirements of the U.S. Army Corps of Engineers and the Council on Environmental Quality, and is intended to reduce duplication. ABSTRACT Covote Creek. The lower Coyote Creek study area is located in the Cities of San Jose and Milpitas, Santa Clara County, south of San Francisco Bay. The U.S. Army Corps of Engineers, San Francisco District, has investigated public concerns regarding flood prevention for Coyote Creek, and associated environmental Impacts. Twelve preliminary structural and non-structural plans were considered to address the flooding from Coyote Creek; four alternatives, including No Action, were selected for detailed study. The Alternate Sides Overflow Channel and Offset Levees Plan meets the planning objectives of prevention of human suffering and possible loss of life, and reduction of damages due to flooding from Coyote Creek. It would include hiking and bicycling trails, and other recreational amenities, to provide aesthetic quality and other recreational values on the east levee along Coyote Creek, and it would reduce floodproofing costs for the Rincon de Los Esteros Redevelopment project. The Alternate Sides Plan was tentatively selected as the recommended plan because it meets all of the planning objectives, and It is the plan which maximizes the net economic development benefits. It would mitigate for adverse environmental impacts includin

VIRGINIA 2104&—9S7« REFL* TO ATTENTION OF: 29 June 1986 SUBJECT: Guadalupe River and Adjacent Streams, California Chief of Engineers Department of the Army Washington, DC 20314-1000 SUMMARY OF BOARD ACTION The Board concurs in the recommendations of the reporting officers regarding improvements for flood control along the Guadalupe River in San Jose, California. The proposed plan consists of 2.5 miles of channel improvements providing 100-year-frequency flood protection to a portion of downtown San Jose. Total first cost of the channel improvements is estimated at $33,015,000, of which $15,386,000 would be non-Federal under traditional cost-sharing polices. The benefit-cost ratio is 1.4. The Board recommends the proposed plan subject to cost­sharing and financing arrangements satisfactory to the President and the Congress. SUMMARY OF REPORT UNDER REVIEW 1. AUTHORITY. The study of Guadalupe River and Adjacent Streams was conducted as part of an ongoing study authorized by section 4 of the Flood Control Act of 1941 quoted in the District Engineer's report. 2. DESCRIPTION OF STUDY AREA. The study area encompasses the 160-square-mile drainage area of the Guadalupe River in central California. The stream rises in southwestern Santa Clara County, flows generally in a northerly direction, and empties into the south end of San Francisco Bay in the vicinity of San Jose. The upstream portion of the drainage basin is characterized by steep mountains that reach elevations of almost 4,000 feet above sea level. In the downstream area, the basin is a large alluvial valley that has been urbanizing rapidly. 3. ECONOMIC DEVELOPMENT. Santa Clara County is a mix of rural steep mountainous terra

Dr. David A. Fredrickson acted as principal investigator~ and Stephen E. Stoddard directed field operations. The report presents the results of archeo1ogica1 in­vestigations into the mechanical impacts, differential preservation, and site preparation for re-flooding, of several prehistoric and historic sites that have been subjected to freshwater immersion be­tween 1957 and 1976. These sites became available for research as a resu1t of the recent prolonged drought in the west. Following the winter rains of 1977 - 1978~ these sites were re-inundated by Lake Mendocino. A total of six archeological sitei were located and prepared accord­ing to the Guidelines Chapter of the Preliminary Report of the Na­tional Reservoir Inundation Study. Information gathered on mechan­ical impacts through field observation was compared to predicted impacts out1ined in the Preliminary Report. The Relat·ive Impact Chart~ which outlines a matrix of soil types and erosional factors, was used

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
