SAN FRANCISCO MARINA RENOVATION PROJECT Final Environmental Impact Report SAN FRANCISCO MARINA RENOVATION PROJECT Final Environmental Impact Report San Francisco Planning Department Case No. 2002.1129E State Clearing House No. 2003122131 Draft EIR Publication Date: September 6, 2005 Draft EIR Public Hearing Dates: October 6, 2005 and January 12, 2006 Draft EIR Public Comment Period: September 6, 2005 – January 20, 2006 Final EIR Certification Date: January 11, 2007 DEFINITIONS Some of the terms used in this document may be unfamiliar to readers. This list of definitions is provided to orient readers to the terms used to describe common features of marinas and waterfront developments that are integral to the project. Please refer to this list as necessary when reviewing the attached Environmental Impact Report. Bow: The front of a boat. Breakwater: A barrier that protects a harbor or shore from the full impact of waves. Dock: A platform that forms the space for receiving or mooring a boat. Fill: The Bay Conservation and Development Commission defines fill as “earth or any other substance or material, including pilings or structures placed on pilings, and structures floating at some or all times and moored for extended periods, such as houseboats and floating docks.” Float: A pier that floats on top of the water, with guide piles driven as needed to maintain its location. Gangway: A bridge for getting to and from floats and docks from the shore. Jetty: A structure, such as a pier, that projects into a body of water to influence the current or tide or to protect a harbor or shoreline from storms or erosion. Mole: A solid fill barrier that protects a harbor or shore from the full impact of waves, similar to a breakwater. Pier: A pile-supported structure over water that extends out from the seawall. Pile or piling: A long, slender column, usually of timber, steel, or reinforced concrete, that is driven into the ground to carry a vertical load. Piers and floating docks are typically supported or secured by pilings. Pilings were historically made of timber and coated with creosote (a distillation of coal tar), a substance that promoted longevity. As creosote is now known to be a contaminant, the Port of San Francisco and several state and federal regulatory agencies require the use of concrete, steel, or pressure-treated wood pilings. Revetment: A facing of wood, stone, or any other material placed to sustain an embankment when it receives a slope steeper than the natural slope; also, a retaining wall. Riprap: A loose assemblage of broken stones erected in water or on soft ground as a foundation. Seawall: A retaining wall that separates land from a body of water. Stern: The rear of a boat.

    Northern Station Newsletter sa nfranciscopol ice. org Sun Francisco -•• - ];''1 Police Deportment (IIII11111111 1U['Di '•- IL' Captain Joe Engler's Message Residents, Merchants, and Visitors, Active and ongoing communication between law enforcement and community members is a key feature of "community policing" and a critical ingredient in the effectiveness of your officers at Northern Police Station. The Northern District embraces a strategy using foot-beat officers in the several commercial corridors of its neighborhoods. Foot patrols cast our officers in the most traditional of police roles. These officers are in direct contact with the public at almost all times and are in the best position to learn about the neighborhood's problems and the path to real solutions. Captain Joseph Eng!er Currently, the following listed officers are contributing to our safe streets and neighborhoods by walking a foot-beat. Officer Matt Horn is the new Hayes Valley/Haight Street beat. Officers Paul Wilgus and Cliff Burkhart walk the beat in Japantown and the Upper Fillmore. Officer Brian Donohue and Calvinn Wang are adept problem solvers in the Lower Polk Street corridor. Officer Nate Bernard peddles the hills and alley ways in the Upper Polk Street neighborhood. Officer Stephen Horn has endeared himself to the Union Street merchants and residents as he returns to his Cow Hollow beat. Sibling Officers Shyrle and Nico Hawes have signed up for the Divisadero Street and Chestnut Street foot beats and will be working closely with businesses to abate the recent spate in shoplifting and car break-ins. Officers Dennis Cesena and Mike Chantal will continue their foot beat duties around the Civic Center and City Hall footprint.

  • Tennessee Erosion & Sediment Control Handbook
    TENNESSEE EROSION & SEDIMENT CONTROL HANDBOOK A Stormwater Planning and Design Manual for Construction Activities Fourth Edition AUGUST 2012 Acknowledgements This handbook has been prepared by the Division of Water Resources, (formerly the Division of Water Pollution Control), of the Tennessee Department of Environment and Conservation (TDEC). Many resources were consulted during the development of this handbook, and when possible, permission has been granted to reproduce the information. Any omission is unintentional, and should be brought to the attention of the Division. We are very grateful to the following agencies and organizations for their direct and indirect contributions to the development of this handbook: TDEC Environmental Field Office staff Tennessee Division of Natural Heritage University of Tennessee, Tennessee Water Resources Research Center University of Tennessee, Department of Biosystems Engineering and Soil Science Civil and Environmental Consultants, Inc. North Carolina Department of Environment and Natural Resources Virginia Department of Conservation and Recreation Georgia Department of Natural Resources California Stormwater Quality Association ~ ii ~ Preface Disturbed soil, if not managed properly, can be washed off-site during storms. Unless proper erosion prevention and sediment control Best Management Practices (BMP’s) are used for construction activities, silt transport to a local waterbody is likely. Excessive silt causes adverse impacts due to biological alterations, reduced passage in rivers and streams, higher drinking water treatment costs for removing the sediment, and the alteration of water’s physical/chemical properties, resulting in degradation of its quality. This degradation process is known as “siltation”. Silt is one of the most frequently cited pollutants in Tennessee waterways. The division has experimented with multiple ways to determine if a stream, river, or reservoir is impaired due to silt.

  • What Lies Beneath the Marina?
    What Lies Beneath the Marina? Robert Bardell 1922 Filbert St. San Francisco, CA 94123 (415) 931-7249 [email protected] A version of this article appeared in the Argonaut Vol. 14 No. 2, Winter 2003, and Vol. 15 No. 1, Summer 2004. What Lies Beneath the Marina? If you answered rubble from 1906, you’re certainly in the majority, but this article will prove you’re absolutely wrong. One of San Francisco’s most enduring myths is that rubble from the 1906 earthquake provided landfill for the Marina District. Extreme versions of this tale claim all the rubble was dumped there; others don’t go quite that far, but all agree the Marina was a convenient dumping ground for the “damndest finest ruins.” A large part of the Panama Pacific International Exposition would later stand on this man-made land—a triumphal symbol for a city celebrating its return from the ashes. It’s a nice story, but completely false. Indeed, the truth turns this story on its head: No significant amount of 1906 debris was dumped in the Marina, and no new land was reclaimed from the tidelands of the bay there until 1912, long after the ruins of the old city had been cleared away and a new San Francisco born. I intend to debunk the myth of earthquake rubble in the Marina with a history of Marina landfill, beginning in the years following California’s admission to the Union and ending with the Panama Pacific International Exposition of 1915. This history will show that the Marina on April 18, 1906 had changed radically from its virgin state, due almost entirely to the effort and capital of one man, James G.

  • Extension of F-Line Streetcar Service to Fort Mason
    UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION IX 75 Hawthorne Street San Francisco, CA 94105 May 17, 2011 National Park Service Denver Service Center – Transportation Division Attention: F-Line Draft EIS Planning Team Post Office Box 25287 Denver, Colorado 80225-0287 Subject: Draft Environmental Impact Statement for the Extension of F-Line Streetcar Service to Fort Mason Center, Golden Gate National Recreation Area, San Francisco Maritime National Historical Park, California (CEQ# 20110079) Dear Planning Team: The U.S. Environmental Protection Agency has reviewed the Draft Environmental Impact Statement for the F-Line Streetcar Service Extension, published by the National Park Service, the San Francisco Municipal Transportation Agency, and the Federal Transit Administration. Our review is pursuant to the National Environmental Policy Act, Council on Environmental Quality regulations (40 CFR Parts 1500- 1508) and Section 309 of the Clean Air Act. The SFMTA proposes to extend the San Francisco Municipal Railway F-Market and Wharves Line (F- Line) approximately 0.85 miles west from the intersection of Jefferson and Jones Streets to the west side of Fort Mason Center. The Draft EIS analyzes the environmental impacts of the No Action Alternative 1 and two options for Action Alternative 2: Alternative 2A – North Loop Turnaround, which would locate the streetcar turnaround in the Fort Mason parking lot, and Alternative 2B – South Loop Turnaround, which would locate the turnaround in the Great Meadow. The Draft EIS also analyzes the environmental impacts of 8 to 9 station platforms and upgrades to the historic Fort Mason Tunnel. The EPA supports improving local and regional transit service connections to National Park Service attractions.
