The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president.
The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. C. D. Mote, Jr., is president.
The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president.
The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

Consensus Study Reports published by the National Academies of Sciences, Engineering, and Medicine document the evidence-based consensus on the study’s statement of task by an authoring committee of experts. Reports typically include findings, conclusions, and recommendations based on information gathered by the committee and the committee’s deliberations. Each report has been subjected to a rigorous and independent peer-review process and it represents the position of the National Academies on the statement of task.
Proceedings published by the National Academies of Sciences, Engineering, and Medicine chronicle the presentations and discussions at a workshop, symposium, or other event convened by the National Academies. The statements and opinions contained in proceedings are those of the participants and are not endorsed by other participants, the planning committee, or the National Academies.

Acknowledgments
This Consensus Study Report was reviewed in draft form by individuals chosen for their diverse perspectives and technical expertise. The purpose of this independent review is to provide candid and critical comments that will assist the National Academies of Sciences, Engineering, and Medicine in making each published report as sound as possible and to ensure that it meets the institutional standards for quality, objectivity, evidence, and responsiveness to the study charge. The review comments and draft manuscript remain confidential to protect the integrity of the deliberative process.
We thank the following individuals for their review of this report: Philip Bedient, Rice University; Timothy Collins, University of Utah; Kimberly Grove, Baltimore City Department of Public Works; Eric Klinenberg, New York University; Ning Lin, Princeton University; Jay Lund, University of California, Davis; David Miller, Electric Infrastructure Security Council; Doug Plasencia, Moffatt & Nichol; and P. Kay Whitlock, Christopher B. Burke Engineering, Ltd.
Although the reviewers listed above provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations of this report nor did they see the final draft before its release. The review of this report was overseen by Michael Kavanaugh, Geosyntec Consultants, and David Dzombak, Carnegie Mellon University. They were responsible for making certain that an independent examination of this report was carried out in accordance with the standards of the National Academies and that all review comments were carefully considered. Responsibility for the final content rests entirely with the authoring committee and the National Academies.
A central part of this study was stakeholder workshops, meetings, interviews, and site visits in four metropolitan areas: Baltimore, Chicago, Houston, and Phoenix. The participants in these activities are listed in Appendixes B through E, and the committee thanks them for their insights on urban flooding in their area. The committee also thanks the following individuals for making maps, compiling data, carrying out literature searches, or making other contributions to the report: Federico Antolini, University of Iowa; Oronde Drakes, University of Iowa; Wesley E. Highfield, Texas A&M, Galveston; Asif Rahman, University of Iowa; Jayton Rainey, Texas A&M, College Station; and Oliver Wing, University of Bristol.
