The Fault Line Threatening Dams
The Fault Line Threatening Dams The Fault Line Threatening Dams Deficient structures, earthquake risks raise possibility of potentially catastrophic flooding By Jim Carlton June 24, 2017 FREMONT, Calif.-The coastal mountains that frame this working-class city next to San Francisco Bay harbor a hidden menace: a reservoir 10 miles away that sits next to an active earthquake fault, which experts say could cause a dam break and flood thousands of homes. The potential threat is so severe, the owner of the Calaveras Reservoir decided to build a replacement dam. But seven years after that work began, the dam is unfinished and isn't expected to be complete until 2019 -- four years behind schedule. The issues hampering the Calaveras Reservoir project show how difficult it can be to repair or replace an old dam, which is of growing concern nationally. An estimated 27,380 dams, or 30% of the 90,580 listed in the latest 2016 National Inventory of Dams, are rated as posing a high or significant hazard. Of those, more than 2,170 are considered deficient and in need of upgrading, according to a report by the American Society of Civil Engineers. The inventory by the U.S. Army Corps of Engineers doesn't break out which ones are deficient. But funding and inspection staffing are considered inadequate, the civil engineers' report said. An estimated $64 billion is needed to upgrade those dams, including $22 billion for those posing the highest hazard, according to the Association of State Dam Safety Officials, a nonprofit group in Lexington, Ky. "It's a huge problem with limited resources," said Ivan Wong, a consulting seismologist from Walnut Creek, Calif., who works on dam projects nationally. -

Appendix D Building Descriptions and Climate Zones
Appendix D Building Descriptions and Climate Zones APPENDIX D: Building Descriptions The purpose of the Building Descriptions is to assist the user in selecting an appropriate type of building when using the Air Conditioning estimating tools. The selected building type should be the one that most closely matches the actual project. These summaries provide the user with the inputs for the typical buildings. Minor variations from these inputs will occur based on differences in building vintage and climate zone. The Building Descriptions are referenced from the 2004-2005 Database for Energy Efficiency Resources (DEER) Update Study. It should be noted that the user is required to provide certain inputs for the user’s specific building (e.g. actual conditioned area, city, operating hours, economy cycle, new AC system and new AC system efficiency). The remaining inputs are approximations of the building and are deemed acceptable to the user. If none of the typical building models are determined to be a fair approximation then the user has the option to use the Custom Building approach. The Custom Building option instructs the user how to initiate the Engage Software. The Engage Software is a stand-alone, DOE2 based modeling program.

The festival is scheduled to occur on May 10th. Updates §1135 Process. Laura Kilgour said that the Corps' Detailed Project Report (DPR) is scheduled to be completed in August 2006, suggesting that project construction is not expected until at least 2008. Dale Boyer noted that lobbying of congresspersons by Workgroup members and agency managers may be beneficial if they urge the Corps' to accelerate its activities. Brenda Buxton re- stated her agency's commitment to help fund steelhead passage projects in Alameda Creek, indicating that the Workgroup should continue to evaluate alternatives to funding via the 1135 Process. With sufficient matching funds, as much as $5 million may be available through the Conservancy. FRW Meeting Minutes: 3.5.2003 1 SFPUC Activities. Josh Milstein told the Workgroup that the SFPUC started the Habitat Conservation Plan (HCP) process for various species of concern occurring on the Alameda Creek watershed properties held by the agency. -
Calaveras Dam Fact Sheet Bcj 091511 V2.Indd
Calaveras Dam Replacement Services of San Francisco Fact Sheet Public Utilities Commission www.sfwater.org/sunolvalleywww.sfwater.org/ulistac 866-973-1476 Calaveras Reservoir Project Summary The San Francisco Public Utilities Commission, operator of the Hetch Hetchy Regional Water System, is rebuilding Calaveras Dam, our largest local Bay Area drinking water reservoir. The existing earth fi ll dam is located near the active Calaveras earthquake fault. We lowered water levels in the reservoir in response to seismic concerns in 2001. The project will construct a new dam equal in height next to the existing seismically-vulnerable dam so that the historic capacity of the reservoir can be restored. The new Calaveras Dam will be one of only a few major dams built in the State of California in the last 30 years. The $416 million project breaks ground in September 2011. The Calaveras Dam Replacement Project is the largest project among the 81 projects of our $4.6B Water System Improvement Program. The Hetch Hetchy Regional Water System delivers drinking water to 2.5 million Bay Area customers. Construction Began: August 2011 Projected Completion: August 2015 Total Project Cost: $416 Million Construction Contractor: Joint Venture of Dragados USA, Flatiron Construction, and Sukut Construction Project Details The project consists of building a new zoned earth and rock fi ll dam immediately downstream of the existing dam. This work will restore the Calaveras Reservoir to its historic capacity. The reservoir provides approximately half of the Hetch Hetchy Regional Water System’s local Bay Area water storage. This storage is crucial to providing adequate water to our customers in times of drought and when Sierra Nevada resources are not available. -
Up Your Creek! the Electronic Newsletter of the Alameda Creek Alliance
Up Your Creek! The electronic newsletter of the Alameda Creek Alliance Alameda Creek Cleanup - November 16 Join the Alameda Creek Alliance this Sunday, November 16th at our adopted site along Alameda Creek, from 10 am to noon at the Niles Staging Area in Fremont. We'll remove invasive plants and pick up trash along Alameda Creek, and discuss how these efforts protect and enhance fish and wildlife habitat. Thanks to all who have helped so far- we've made great progress on ivy removal, but there is more to be done! We’ll meet at the Niles Staging Area parking lot along Old Canyon Road at Canyon Oaks Court in the Niles area of Fremont. Wear work clothes, including long pants and sturdy shoes that can get dirty. A long-sleeve shirt and hat are recommended. We’ll provide gloves, waste bags, litter grabbers, water, and a snack. Please bring your own re-usable water bottle to fill. RSVP to Ralph Boniello at [email protected]. Talk On Raptors, Rats, and Riparian Areas November 19 Lisa Owens Viani, co-founder and director of Raptors Are The Solution (RATS), will talk about raptors and the threats they face, particularly from rat poison, and also discuss less toxic ways of controlling rodents. The talk will be on Wednesday November 19 at 7 pm at the Dimond Branch Library, 3565 Fruitvale Avenue in Oakland. Owens Viani will describe a nine-year study of Cooper’s hawks in Berkeley and their connection to riparian habitat, as well as how the study led to the formation of RATS.
