Final Reconnaissance Report Ocean Beach General Investigations Reconnaissance Storm Drainage Reduction Study City And County Of San Francisco

The report presents information developed in the course of a multi- year investigation of the need for shore protection and storm damage reduction. The study area was 8.6 miles of the Pacific coast, known as Ocean Beach, in the City of San Francisco, CA. The study area extended from Cliff House to Fort Funston. The beach portion of the study area is in the Golden Gate National Recreation Area, under the jurisdiction of the National Park Service. Facilities threatened with damage included the Great Highway, parking lots of the GGNRA, a buried storm and sewer water transport box, a sewer pumping plant and ultimately houses and businesses. The report records the Ocean Engineering, Economic, and Geotechnical studies used to formulate and analyze a variety of alternative measures, including structural seawalls and revetments, as well as beach and dune nourishment. The final analysis indicated that most of the study area, while not absolutely safe, had a low probability of erosion. In the one area with a possible federal interest, the sponsor was unable to agree to cost share at the time of the report. Therefore the study was terminated. The sponsor will pursue other measures not requiring federal cost sharing.

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

A compendium of studies, investigations, and research efforts undertaken since 1970 or ongoing at present and related to disatster preparedness, assistance, mitigation, and hazard reduction of natural disasters in the United States.

"You can't really know the place where you live until you know the shapes and origins of the land around you. To feel truly at home in the Bay Area, read Doris Sloan's intriguing stories of this region's spectacular, quirky landscapes."—Hal Gilliam, author of Weather of the San Francisco Bay Region "This is a fascinating look at some of the world's most complex and engaging geology. I highly recommend this book to anyone interested in an understanding of the beautiful landscape and dynamic geology of the Bay Area."—Mel Erskine, geological consultant "This accessible summary of San Francisco Bay Area geology is particularly timely. We are living in an age where we must deal with our impact on our environment and the impact of the environment on us. Earthquake hazards, and to a lesser extent landslide hazards, are well known, but the public also needs to be aware of other important engineering and environmental impacts and geologic resources. This book will allow Bay Area residents to make more intelligent decisions about the geological issues affecting their lives."—John Wakabayashi, geological consultant

Prepared byØtheØTask Committee of the Urban Water Resources Research Council of ASCE. Copublished by ASCE and the Water Environment Federation. Design and Construction of Urban Stormwater Management Systems presents a comprehensive examination of the issues involved in engineering urban stormwater systems. This Manual?which updates relevant portions of Design and Construction of Sanitary and Storm Sewers, MOP 37?reflects the many changes taking place in the field, such as the use of microcomputers and the need to control the quality of runoff as well as the quantity. Chapters are prepared by authors with experience and expertise in the particular subject area. The Manual aids the practicing engineer by presenting a brief summary of currently accepted procedures relating to the following areas: financial services; regulations;Ø surveys and investigations;Ø design concepts and master planning;Ø hydrology and water quality;Ø storm drainage hydraulics; andØ computer modeling.

The classic work on the evaluation of city form. What does the city's form actually mean to the people who live there? What can the city planner do to make the city's image more vivid and memorable to the city dweller? To answer these questions, Mr. Lynch, supported by studies of Los Angeles, Boston, and Jersey City, formulates a new criterion—imageability—and shows its potential value as a guide for the building and rebuilding of cities. The wide scope of this study leads to an original and vital method for the evaluation of city form. The architect, the planner, and certainly the city dweller will all want to read this book.
