Basin Plan San Francisco Bay Water Quality Control Plan, By law, the Water Board is required to develop, adopt (after public hearing), and implement a Water Quality Control Plan (Basin Plan) for the San Francisco Bay region. The Basin Plan is the master policy document that contains descriptions of the legal, technical, and programmatic bases of water quality regulation in the San Francisco Bay region. Baseline Program Before MCSTOPPP obtained coverage under the Phase II General Permit, it operated a Baseline Program as a result of Basin Plan requirements. The Baseline program was designed to ensure no net increase in stormwater pollutants from the area. BASMAA Bay Area Stormwater Management Agencies Association, which is compiled of nine stormwater programs throughout the Bay Area to share information and resources and to find opportunities for joint projects. BMPs 1. Practices implemented by private industry and public agencies that prevent or reduce water pollution. 2. Schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce the pollution of “water of the United States.” BMPs also include treatment requirements, operating procedures and practice s to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.

Jerry Davis, Ph.D. Professor and Department Chair of Geography & Environment Leonhard Blesius, Ph.D. Associate Professor of Geography & Environment CARTOGRAPHIC COMMUNICATION FOR A SEARCH AND RESCUE MAP Mitchell Wilks San Francisco, California 2018 Cartography is a critical element of search and rescue (SAR), with which map makers and map viewers visualize and communicate. This study, in four steps, evaluated the existing 2011 Marin Municipal Water District (MMWD) SAR Map, produced the 2018 MMWD SAR Draft Map, assessed the usability of the Draft Map, and produced the 2018 MMWD SAR Updated Map. In the evaluate-produce-assess-produce steps, the needs and biases of respondents were articulated in the evaluate-assess steps and informed each production step. The result was a map optimized for use in SAR operations on MMWD by the respondents. I certify that the Abstract is a correct representation of the content of this thesis.
