The document, together with the accompanying Response to Comments, will be filed as the final SEIS. Lead Agency The Presidio Trust (Trust), a federal government corporation and executive branch agency created by Congress in 1996, is the lead agency for the action analyzed in the final SEIS under the National Environmental Policy Act (NEPA). The Trust oversees the interior 1,168 acres (Area B) of the Presidio of San Francisco (Presidio), while the National Park Service manages the 323 coastal acres (Area A) of the former military post.

  • Research Advocacy Education
    RESEARCH EDUCATION ADVOCACY 2016 SPUR brings people together to develop solutions to the big problems cities face. We work across the Bay Area, with offices in San Francisco, San Jose and Oakland. We do our work in three ways: 9 Research We identify pressing problems and develop strategies to solve them. 14 Education We engage people in the life of their city. 21 Advocacy We work with decision-makers to get our proposals put in to practice. RESEARCH SPUR Report: Seamless Transit The Bay Area’s public transit system is notoriously fragmented. Riders contend with more than two dozen different operators with divergent maps, schedules and fares — not to mention uncoordinated capital planning and investment. SPUR’s report Seamless Transit proposed a set of recommendations to make the region’s transit function like one rational, easy-to-use system. Our proposals gained support from Bay Area residents, employers and city leaders who want to grow transit usage. It also sparked a national conversation, with coverage in The New York Times and The Washington Post. In response to the study, transit agencies and the Metropolitan Transportation Commission have begun collaborating to coordinate their transit infor- mation, create regional fare passes that work on multiple operators and design new transit hubs for seamless connections. Getting to Key South Bay Destinations Santana Row and Valley Fair are magnets for millions of visitors who come to shop, eat, work and people-watch every year. Due to their economic success, both are plan- ning to expand. A case study in retrofitting suburbia, these retail and entertainment destinations bump up against low-density development and are primarily accessible by car only.

  • 3.8 Soundscape and Noise
    Soundscape and Noise 3.8 SOUNDSCAPE AND NOISE This section describes the existing soundscape and noise environment in the project area and identifies sensitive land uses or land use activities to define the affected environment for later assessment of noise and vibration impacts on humans. Noise effects on marine and terrestrial wildlife as a sensitive receptor vary by species and a number of biological factors, and those environments and effects are addressed in Sections 3.5 and 4.5, Biological Resources, respectively. 3.8.1 Noise Concepts and Terminology Sound is mechanical energy transmitted by pressure waves through a medium such as air. Noise is defined as unwanted sound. Sound is characterized by various parameters that include the rate of oscillation of sound waves (frequency), the speed of propagation, and the pressure level or energy content (amplitude). In particular, the sound pressure level has become the most common descriptor used to characterize the loudness of an ambient sound level. Sound pressure level is measured in decibels (dB), a logarithmic loudness scale with 0 dB corresponding roughly to the threshold of human hearing and 120 to 140 dB corresponding to the threshold of pain. Because sound pressure can vary by over one trillion times within the range of human hearing, the logarithmic loudness scale is used to calculate and manage sound intensity numbers conveniently. The typical human ear is not equally sensitive to all frequencies of the audible sound spectrum. As a consequence, when assessing potential noise impacts, sound is measured using an electronic filter that deemphasizes the frequencies below 1,000 Hertz (Hz) and above 5,000 Hz in a manner corresponding to the human ear’s decreased sensitivity to low and extremely high frequencies instead of the frequency mid-range.
