SRT is a slope reinforcement technology that uses rigid steel Plate Pile™ elements to stabilize shallow failing slopes or reinforce marginally stable slopes. The use of small, mobile equipment allowed for the work to be performed directly on the slope with no interruption of traffic. This project demonstrated that the SRT system can successfully be installed along roadways with difficult access, while decreasing construction time and earthwork operations. ©2014 Geopier Foundation Company, Inc.

San Bernardino & Riverside Counties Branch Los
SAN BERNARDINO & RIVERSIDE COUNTIES BRANCH LOS ANGELES SECTION , REGION 9-SINCE 1953 PRESIDENTS MESSAGE September 2012 The 2011-2012 fiscal year of the branch is coming to an end, and I would like to take this opportunity with my last president message to thank each board member for their dedication, hard work and commitment to the San Bernardino and Riverside Counties Branch. We had an excellent year and it would not have been possible without their help. Although there have been many challenges, there have been even more wonderful memories made during my journey as president that will always hold a special place in my heart. We’ve had many successful events this past year such as lunches with great speakers, our tour to the American Asphalt Company, Engineering Week, and the golf event to name a few. I sincerely hope that all of you enjoyed these events that we prepared for you. I also want to encourage all NEWSLETTER of you to voice your opinion. Let the new Board members know which events worked the best and even share some topics or ideas that you may have for a lunch meeting. This is the time to do it, as they will be happy to incorporate any feedback that you have. With your input, I am confident that next year will be just as successful as this past year has been. Finally, I would like to say that it has been an honor and a pleasure to serve you as the 2011- 2012 branch President and I want to thank all the members for their continued support and com- mitment to the San Bernardino and Riverside counties Branch. -

Memorial Tributes: Volume 5 HARRY BOLTON SEED 247 Harry Bolton Seed 1922–1989 By James K. Mitchell Harry Bolton Seed was born in Bolton, England, on August 19, 1922. He studied at King's College, London University, receiving the B.Sc. in civil engineering in 1944 and the Ph.D. in structural engineering in 1947. Following two years as assistant lecturer at King's, he came to the United States to study soil mechanics at Harvard University under the tutelage of Karl Terzaghi and Arthur Casagrande. He received the S.M. from Harvard in 1948 and spent the next year as an instructor. This was followed by a year as a foundation engineer for Thomas Worcester, Incorporated, in Boston. In 1950 Professor Seed joined the civil engineering faculty at the University of California, where he spent the remainder of his career as an engineering educator, researcher in geotechnical. engineering, and consultant to numerous companies and government agencies. He built the program in geotechnical engineering at Berkeley into one of the largest and best in the world. A major factor in this development was his bringing colleagues together from different areas of geotechnical engineering, including geological engineering and rock mechanics, as well as soil mechanics and foundation engineering. He served as chairman of the Civil Engineering Department from 1965 to 1971, a period during which it rose to number one ranking in the United States for the quality of its graduate programs. Professor Seed had an enormous impact on every area of Copyright National Academy of Sciences. -
