the damn that same study concluded that if a magnitude 7.2 or greater earthquake struck the nearby calaverasould essentially liquefy risking a major water release from the reservoir and putting the people who live below the dam in danger. in order to fix the problem, the district wants to drain the reservoir and retrofit the damn starting in 2015, but california and the bay area are facing a third straight year of drought conditions and there's concern that if the dry weather persists... draining this key water supply could be a bad decision. the district says that anderson reservoir will remain in use for the rest of this year and that if the drought continues, they could delay the work. it is possible that the drought occurring at the time when we had been planning to start this project could pose a big water supply problem. so we are currently assessing what kind of parameters we would use to either go or not go with the project any decision would need approval from both state and federal regulators. in santa clara county, charles clifford kron 4 news. and this coming sunday night at 9pm.

the thought is that a 6.6 earthquake, that would be a large shaker on the calaveras fault could bust this dam and send a wall of water that would flood. experts say there is a slim chance of that happening but still it is a possibility. and the precaution. the project would run around $123 million. it would shore up the dam. here's the part about this that has some scratching their heads. in order for workers to fix the dam t district would have to drain the reservoir even though we're in the middle of a drought. >> we're asked to on serve water, i conserve, but then water's just disappearing. >> the timing is difficult, we're obviously in a drought right now. like we don't have to make that decision today. >> reporter: the draining would likely take place fall of next year, 2015. whatever water is drained would be diverted to treatment plants and into the ground water supply because of the dam's condition, because it's seismically unsafe t district is only allowed to fill to 68% of capacity, if you get much higher you have too much pressure and the fear is it would bust. the distric

there have been cost increases in some of the projects including calavera dam replacement which is a corner system of our system and we are having to repair that dam and because of changes in geologic conditions we found there, we need to in accrues -- increase that project by $120 million. that money had to come from somewhere in our program and so we have delayed construct of the desalination in our project. we still have about $8.5 million. we have to decide if we'll do the project and finish those things that we are committed to and make sure our system runs efficiently. i will be happy to answer any questions. >> thank you, mr. richie. supervisor tang, any questions? okay. thank you. mr. rodriguez from the environment department. >> good afternoon. i want to spend some time to talk about education activities that our department takes in support to get around conservation to city san franciscans and water users and we play a role to sf puc and do many activities. one that i wanted to focus on our if i can is our school education program and working with san francisco unified and

i must say, the biggest challenge of the program going forward is the calaveras damn replacement project. this project you heard about in the past is the largest project in the program one of the most complex. in 2012, we discovered an ancient landslide during construction that increased the amount of volume needs to be excavated by more than 3 million yards and you can see the an excavation being made. there is a large cut that is about 500 feet high that you can see. to date we have another 200 feet to go to the bottom of the valley. in 2012 we also recognized there was another feature called area b which was another suspected landslide but it couldn't be determined until we got to that level. it has been confirmed that there is another ancient landslide that needs to be removed. that is another half or so cubic yard with respect to excavation. we have done geologic exploration to make sure we find the limits of that additional feature. we are currently evaluating the schedule and cost impacts associated with that feature and we expect to have those numbers in the next couple of months

there are other projects that we've put in the program and they increased in size, like cal var ~ calaveras, for example. we want to let you know once you get involved and start seeing more, some of the scope increases. >> i guess i was just really concerned that since this particular tunnel provides, i guess, over 80% of the water to the bay area and san francisco, this kind of concern probably should have been discovered and addressed many years ago. so, i guess i'm just -- now, you know, a significant cost. now it's something of an emergency. now the possibility of it impacting, you know, how we can move forward even with our clean power program and other things just really disturbs me. >> well, let me just point out the water system improvement program we started in 2002, $4.6 billion, we recently invested in that. and i tell you, those projects to me were very important because they're right by seismic faults. and, so, you have to prioritize. the system is over 100 years old. so, we know we need to reinvest in there. we can identify 7, $8 billion we need to invest in there so we need t

again, the thought is that a 6.6 quake on the calaveras fault could burst this dam, send a wall of wattey're would flood gilroy, morgan hill, san jose, experts admit there is a slim chance of that happening, but they still say it is a possibility. the planned $123 million project was shored up to withstand a big quake. here is a part of this that has some scratching their head. to fix the dam the district would have to drain reservoir even though we're in the middle of a drought. >> we're asked to conserve water, i conserve but water is just disappearing. >> the timing is difficult, we're obviously 18 drought right now. we don't have to make that decision today. >> the draining would likely take place in the fall of next year, 2015. whatever water is drained would be diverted to waste water treatment plants and into the ground water supply, because of the dam's condition and the inside t district is only allowed to fill to the 68% capacity. but they have been extra cautious keeping it at 48% capacity. it's possible let's say this drought keepis going on they could appeal to the state an

and a recent study found that a magnitude 7.2 or greater earthquake struck the nearby calaveras faultis dam would essentially liquefy risking a major water release from the reservoir. in order to fix the problem, the district wants to drain the reservoir and retrofit the damn starting in 2015. but the district feels with the state's ongoing drought, draining the dam is not a good idea and trying to make a decision right now. because of the ongoing drought, the santa clara valley water district could delay a long planned seismic retrofit. of the anderson dam near morgan hill. kron 4's charles clifford. in the south bay today. to update the situation. we're coming up on 4-30. here are the big stories we're working on for you this morning. in pittsburg yesterday. rule timethis is video from our helicopter partnership with a-b-c 7 news. 40 acres burned. the search is on for the driver of an s-u-v, that hit and killed a pedestrian. it happened just after 11 - a-m. in san francisco's visitation valley. police say, a woman in her 60's, was crossing the street, when the driver made a left han
