The savings targets are really unrealistic and possibly even illegal under current water laws. But the thing we should stress is this is legislation thats proposed. Even a threat of the fine. If you want to rattle cages he got their attention. Meanwhile perfectly good groundwater is being pumped straight to the storm drains in one bay area city. New at 6 00, kpix 5 is in palo alto where the city cant seem to stop the water wasters. Theyre building a basement which requires them to pump water out of the ground all day every day. Tens of thousands of dollars of water literally going down the drain. Reporter this is what the city of palo alto calls dewatering. A common construction practice in which thousands of gallons of water are pumped from the ground to build a basement. In a time of severe drought neighbors call it Something Else entirely. This water could be used for other purposes. Reporter the citys Public Work Department estimates the contractor at one construction site could pump as much as 50,000 gallons of water out of the ground a day. Some of it is collected, stored, and later used to water landscaping. But most of it is simply dumped down the storm drain. A practice that assistant director of public works says is less wasteful than it might appear. This shallow groundwater is moving toward our creeks and toward San Francisco bay. So when they pump it out and put it in the storm drain system, its really just a different pathway to the bay. It still ends up in the same place. Reporter with the governor calling on californians to cut their water use by 25 many neighbors say its tough to see so much watering being sent down the storm drain day after day week after week. Even though it may not be drinkable kind, with the shortage that we have for water this could water the lawns. Reporter the Public Works Department says the city council could require contractors in the future to collect more of the water they pump from the ground. But says in many cases it simply isnt feasible or necessary. The water isnt really being wasted. Either way it goes to San Francisco bay. Either via the groundwater or via the storm drain system. According to the city, the groundwater pumping goes on continuously during construction typically until the basement is complete which in this case will be several more months but in other construction sites has dragged on for years. East bay mud plans to pump in nearly 7 billion knalens from the Sacramento River to keep the reservoirs full through the summer. It would come from three different water districts which still have to approve the transfer. At nearly 15 million, the extra water wont be cheap. Customers would cover the cost through a temporary drought surcharge. Its been a big debate here in california for a while and today the battle over samesex marriage reached the u. S. Supreme court. The nine justices heard two hours of oral arguments for and against legalizing samesex marriage. The high court is looking at cases from four states where a federal court upheld the marriage bans. Right now it appears the four conservative justices are against samesex marriage and the four liberal justices are for it. Justice kennedy could be the swing vote. A big rally is underway in support of legalizing samesex marriage. Weve got a couple hundred people here rallying in support of samesex marriage. Just a couple hours after the argument was made before the u. S. Supreme court in washington, d. C. Theyre gathered here on the steps of San Francisco city hall where it all began. Many of the ralliers have watched every court case very closely ever since approved 11 years ago. Some here say they thought todays questionandanswer session sounded a bit out of touch. For example when Justice Kennedy wondered allowed why the court should change the definition of marriage when its been between a man and women for so many millennia as he put it. Former assembly tom omiano here who once marched the streets with harvey milk. I dont appreciate this being an issue saying hmm its always been this way. That shows how narrow their view of history is. Who wrote that history . Maybe people who are not necessarily willing to acknowledge gay people. It is of course impossible to know which way the justices were leaning just by virtue of their questions. Past Supreme Court cases have taught us that lesson. Well have to wait for the answer until june when the Supreme Court is expected to make its decision. Joe vazquez kpix 5. Cbs news chief Legal Correspondent jan crawford was at the u. S. Supreme court for todays arguments. She explains why it could all come down to one man. Justice anthony kennedy. Today he asked very tough questions from both sides. He started off by kind of stressing the gravity and magnitude of this decision, saying this has been the definition, the traditional definition of marriage has been in place for millennia and that theyre asking for a change in that definition but then later in the argument he seemed troubled by points that samesex couples of course wanted to have children and be apart of a loving and committed family, really pushing back on opponents of samesex marriage so he was tough to read and at the end of the day this could all come down as it has in the past to Justice Kennedy. Who gave the most compelling argument today . I think where the argument really went off the rails for opponents of samesex marriage was when they started trying to justify why those bans of samesex marriage were in the governments interest. Then they have to fall back on the interest that the marriage is in support of procreation. Those really gave the lawyers a lot of trouble. Justice kennedy and those arguments that line of questioning was very skeptical. Hard to justify. I think that was quite a difficult part of the argument today. As joe mentioned just a minute ago the u. S. Supreme court will release its ruling in june. Voters will have the last word on whether to legalize marijuana in california. As that debate plays out Mike Sugerman says San Francisco is already planning for legal pot. Reporter he was the first person in San Francisco to blow smoke legally. He got the first Medicinal Marijuana card after he helped write the state proposition that legalized it. Now he expects everyone to be able to do the same thing. Get out of the way because here it comes. Reporter legalize cannabis is expected to be on the november 2016 ballot but signatures havent been turned in yet. Its lost twice on previous ballots, nonetheless the San Francisco supervisor says its time to prepare. I think it will be a complete mess if we wait for it to pass and then decide oh, yeah lets wake up and decide how to regulate it. Lets think about that now. Reporter scott is calling for a task force to be set up ignoring arguments that surely will come during the campaign that legalization will lead to more use and addiction that kids will get their hands on it. Theyre going to be worried about where and how will the distribution be done. Before the distribution, where and how is the cannabis going to be grown . Reporter justimon set up a task force that set up the card program and zoning laws. Now theres another issue. Money. Taxes could be a windfall for the city maybe. Depends how the structure but i think theres a decent chance that local jurisdictions will have the power to tax. Reporter in colorado the state made 44 million taxing nonMedicinal Marijuana. Theres a 10 sales tax and 15 excise tax. Thats if and when california does finally go to pot. Mike sugerman, kpix 5. Near ly 2 3rds of california supports legalizing regulating and taxing marijuana.

Its about how can we better build trust in our community.

Reporter hes helping introduce ab 1113, the bill would change how officers engage the citizens they serve by improving Community Relations through training at every level. Especially with todays climate, its evermore critical. Reporter cities like baltimore, maryland have been flash points for violence and explosive protests against police tactics. Some say this anger is fueled by how people of color are treated by officers. At the center of the conflict is a lack of trust. There are higher levels of mistrust in certain communities especially those communities that need us the most. Many times communities of color. Reporter chief jones says it would improve the trust by creating intense mandatory Community Relations training for all officers in california. Thats what the training is about, discussing that and the training excludes community input. Reporter chief jones says the goal is to avoid the recent violent protest making headlines across the country. The oakland stockton, and Salinas Police departments have already implemented intense Community Relations, training for their officers and staff.

My dad named me everest because he wanted to climb Mount Everest but my mom wouldnt let him. Reporter she must have been thrilled last year when for his 16th birthday the danville father and son made the trek to visit base camp at the foot of Mount Everest. The exotic feel of nepal and the warmth of its people gave everest what he calls the greatest experience of his life. And then came last saturday. The ancient city of kathmandu was no match for the 7. 8 quake. Buildings are in ruins. Centuriesold temples have collapsed. And the magical place everest remembers is simply not there anymore. I cant even imagine going to the same place back in nepal and looking at nothing. I cant even comprehend it. His first reaction was lets go. Lets help them.
