deep. >> it is unsustainable for this to continue and something has to change. safety changes coming to the busy intersection where a crash killed a family of four, but not everyone in the neighborhood feels the plan to restrict cars is the right reaction. >> i think it's going to be rougher for people to get down here or want to come down here. ♪ san francisco open your golden gate ♪ as san francisco marks the anniversary of the earthquake that nearly destroyed the city, it's a chance to take stock before the next big one. an expert weighs in on what you really need to have ready to go. >> the most important thing is look, it all fits in a backpack. throw it in your car trunk. it's there when you need it. this is cbs news bay area with juliette goodrich. >> hello. i'm sara donchey in for juliette. it's an expensive fix for a serious problem. land is sinking so fast in the central valley a crucial canal failed. now the new canal they just

built to replace it is sinking as well. we're talking about the friant kern canal near the san joaquin valley. the system starts at millerton lake north of fresno and runs 152 miles south powered entirely by gravity, but gravity means going downhill and that has gotten complicated, simple as it sound. decades of groundwater pumping have caused valley floors to sink and the canal right along with it. >> to convey this water south through this section, we've lost over 60% of the carrying capacity. >> so we first showed you the solution back in august 2022. it is a new canal built right alongside the old one, only it's higher so the water can still flow downhill. that new canal will go into service in the next couple weeks and as wilson walker shows us, it's already facing the very same challenge as the first one.

>> reporter: you're looking at in the foreground the old canal and over that dirt pile there is the new canal. this is typically an image people look at and think oh, my gosh, what kind of problem do you have to solve out here and that's it. stretching out across ten miles of tulare county is a quiet california mega project that is just about finished. it is the new friant kern canal. the old canal built in the 1940s has been sinking with the valley floor since the time it was built. it was raised in the '70s, but the subsidence has continued and with capacity cut by 60%, the only option was a new canal, but it faces the same old problem. >> i've got some poster boards for you, wilson. this will blow your mind. >> reporter: donnie amroall is

chief operating officer of the friant water authority about to celebrate the grand opening of this 300 $300 million for a quarter million people. >> we've encountered a new area of subsidence creating a capacity problem in our new canal. years of planning, tricky financing and on day one we're facing about a 400 cfs capacity problem on day one of this new canal. >> reporter: that is new sinking threatening the very project that was supposed to keep the water moving. >> it's not rocket science what the cause is. it's overdraft of groundwater. >> we grow crops to feed the cows that makes the milk that makes land o'lakes butter in our local plant in tulare. >> reporter: tom is a third generation dairy farmer who

relies on the canal. >> investment companies are coming in to put in orchards and vineyards and next thing you know, they're just drilling deep, deep wells. where my wells were 300 and 400 feet, they're drilling 1,200 feet to 1,800 feet a drawing the deepest water. >> it's a touchy subject because we're talking about neighbors, friends, people we've known for many, many years. >> reporter: for the water authority their sinking canal is forcing the issue. they're asking the state for an emergency intervention on groundwater usage in this basin. >> i hear that quite a bit, why are you picking a fight with fellow farmers? and my response is what are we supposed to do? what are we supposed to do? this is the most important infrastructure facility on the east side of the san joaquin valley and it's being harmed and damaged every day. >> the challenges are in a sense pitting farmer against

farmer in a way because who's pointing fingers at who? the challenges are deep. >> reporter: deep enough to cut into the capacity of this region's emergency subsidence fix before it even opens. what scares amorall even more is california doesn't have a plan to reach groundwater sustainability until the year 2040. >> our problem is it's got to be addressed really soon because in order to realize the full capacity to move water through the new canal, this capacity problem has to be addressed immediately. >> reporter: the new canal was built with future subsidence in mind. these giant siphons that pull the water beneath the roadways, that would allow them to raise this canal in the future without having to lift all of the bridges like they had to do back in the '70s. thinking about the canal sinking, the landscape sinking, everything out here subsiding really forces you to use your imagination when thinking about

the state's water challenges. so this massive project will open to a number of questions as california's water landscape changes in more ways than one. >> wilson tells us the ribbon cutting and flooding of the new canal will come in the next couple weeks. the state is expected to hold a hearing on the groundwater issues in the tulare water basin in september. changes could be in store at the site of that deadly pedestrian crash that killed a family of four last month. the city of san francisco is looking at redesigning the traffic flow in part of the west portal neighborhood. a mom, a dad, and two young children were waiting at a bus stop when police say a speeding driver hit and killed them on march 16th. anne makovec has more on plans and reaction from people who live in the area who aren't sure this is the best solutions. >> after that deadly agencies from police to public works tried to come up with ideas that could have prevented such a terrible tragedy. here's what muni came up with as a draft

proposal. this is the area outside the west portal transit station and this reconfiguration would prevent cars from driving through the intersection of ulloa street and west portal avenue, eliminating left hand turns from drivers heading toward the station. muni says this would clearly define where pedestrians, vehicles, and buss could go and remove vehicle traffic from the train tracks. director of the mta says it's all about safety for all involved. >> and also to help expand upon the vibrant commercial life of the west portal corridor by creating a grand entry plaza. >> some of the business owners are not sure if muni's solution is the right one. >> that accident that we had was tragic, but, you know, we really don't have any data to

support that it's a problem. >> i think it's going to be rougher for people to get down here or want to come down here. i keep saying when they close down market street for through traffic, all things went bad from there and it hasn't recovered and i feel doing something that major to a little area that's been working like this so long will really make a big, huge impact on everyone. >> it's not a done deal. muni scheduled three public meetings about this in the weeks to come. the merchants are planning on having some meetings of their own. >> interesting to see how that shakes out. we'll monitor those meetings. thank you. just yesterday san francisco police set up this sting operation in west portal. the assistant chief there in plain clothes tested drivers to see if they'd slow down for him as he walked in the crosswalk. nearly two dozen drivers were ticketed in just 90 minutes. other stories we're following around the bay, a driver was killed after a car went 200 feet down over a cliff

four different times. >> the suspects are held without bail in the santa clara county jail. we've confirmed that one of the suspects is also alleged to be involved in a string of organized retail thefts. duc nguyen was arrested earlier this month in connection to a retail theft ring responsible for $150,000 worth of stolen goods. authorities say they teamed up with home depot, target, kohl's, lowe's, macy's and sunglass hut to recover the items. still ahead, san francisco reflects on the earthquake that leveled the city and lessons learned 118 years later and a chance to ask how prepared are you for the next big one? an expert shows us how to put together that critical go back. starting to see fog developing along the coast, the marine layer reestablishing itself and that fog will be widespread across the bay area beginning the

we're following breaking news out of alameda county. d.a. pamela price announced her office is filing involuntary manslaughter charges against three alameda police officers involved in the in-custody death of mario gonzalez. it happened in 2021. gonzalez was suspected of stealing alcohol and during his arrest officers pinned him to the ground until he went limp and died. a coroner's report pointed to a combination of drugs along with physical stress of the confrontation of the officers. former d.a. o'malley had previously declined to prosecute the three officers, but when price took office, she said she planned to take another look at the case. the city of alameda reached two settlements with gonzalez's

family, one worth over $11 million. we had another really nice warm day today, but, paul, i guess there are changes looking out ahead. >> or even about 12 hours down the line because the marine layer is getting its act together and will push fog across the bay area heading into early tomorrow morning. temperatures will be cooler, still slightly above average farther inland. here's the view from salesforce tower looking west seeing the fog coming over the hills away from the coast. it will be widespread and dense to begin the day on friday. allow extra time for the morning commute. we'll see the pattern repeat itself tomorrow and saturday, the morning fog giving way to afternoon sunshine and temperatures slightly above average inland. everybody warms up sunday and monday as the marine layer gets suppressed. bigger changes on the way next week. cooler temperatures settling in beginning tuesday, maybe a chance of showers by the end of next week. let's look from a different perspective, the santa clara valley, not seeing fog, just high clouds overhead. it's 72 degrees in san jose,

77 in concord, but there's the influence of the marine layer, upper 50s in both oakland and san francisco. reduced visibilities for most of the bay area to begin the day friday. you can see the fog pushing well into the inland valleys late tonight into early tomorrow morning. it backs up out of the inland valleys by 9:00, 10:00, but for san francisco and along the coast it will take until late morning to around midday for the fog to finally retreat and visibilities to improve. we will see temperatures warming up once the fog dissipates. tonight forecast lows dropping to a mix of upper 40s and low 50s by early tomorrow morning. everybody is within a few degrees of 50. once the fog dissipates inland temperatures warm up, a foggy start for angel in santa rosa, but she can frolic in her favorite field once temperatures climb quickly once the fog is gone from 50 degrees at 9:00 a.m. to above 70 degrees in the afternoon. for friday things

look mild in the santa clara valley, 6 or 7 degrees above average, 77 in san jose, one of the warm spots across the entire aye area along with antioch making it to 78 degrees, not quite that warm for fremont and redwood city, low 70s, upper 50s for half moon bay, 58 today and again tomorrow. san francisco got up to 70 degrees early this afternoon, but temperatures have tumbled since then and tomorrow low 60s. the influence of the fog in the north bay will hang on a little longer than other inland parts of the bay area. temperatures only top out in the low 70s for the inland valleys in the north bay. let's look what happens heading farther down the line, if the map works for me. there we go. pollen count climbs into the high category saturday and sunday and again monday. no rain to wash the stuff out of the atmosphere until likely after the seven-day forecast. we'll be looking at the six to ten-day outlook through the

following weekend, a decent chance of wetter than normal conditions associated with a cooler than average pattern that begins by tuesday. enjoy the warm weather while it's here. let's check out the seven-day forecast. we'll start with inland parts of the bay area. we're closer to normal high temperatures the next couple days, but back up to around or above 80 degrees on a widespread basis by sunday and monday and then temperatures do drop off by tuesday, wednesday, thursday. in fact, below average readings are likely as we head through the majority of the last full week of april despite the warm start monday. temperatures around the bay, similar roller coaster ride, close to normal the next couple days, above normal sunday and monday and down the other side of the roller coaster tuesday, wednesday, thursday. 24 hours ago we had a chance of showers wednesday. backing off on that. i think we'll see plenty of cloud cover wednesday and thursday next week, but any decent chance of rain looks like it's holding off until thursday or friday, a 20 to 30% chance, nothing to get too

excited about. a special reunion on the peninsula between some real life heroes and people's whose lives they saved in a crisis.
