Federal Emergency Management Agency (FEMA), Building Seismic Safety Council (BSSC) and U.S. Geological Survey (USGS) act cooperatively to develop the seismic design value maps. The current maps have undergone an evolutionary process over the past 30 years, with major innovations introduced approximately once every 10 years through efforts known as Project 97, Project 07, and Project 17. This Project 17 report documents the activities and recommendations to develop a consensus basis for next-generation seismic design value maps and/or tools for adoption by the 2020 NEHRP Recommended Provisions for New Buildings and Other Structures (NEHRP Provisions). These recommendations were prepared by a joint committee of volunteer engineers empaneled by the BSSC and USGS engineers and scientists and funded by FEMA.
