  • Housing act gives purchase power to San Francisco nonprofits - Shareable
    https://www.shareable.net/housing-act-gives-purchase-power-san-francisco-nonprofits

    The San Francisco Bay Area has been experiencing a housing affordability crisis for quite some time now. Homelessness has reached unprecedented levels, evictions have skyrocketed, and many people are finding it difficult to live in the cities they work in. It’s the magnitude of this crisis which compelled San Francisco’s Board of Supervisors to unanimously pass a piece of legislation this month that could give a big boost to affordable housing in the Bay Area.

    The Community Opportunity to Purchase Act, or “COPA,” is the result of years of organizing by housing rights organizations. The act makes it easier for housing nonprofits (including land trusts) to compete in a market that is currently dominated by giant developers and speculators.

    COPA does this through two policies: the right of first offer and the right of first refusal. The former requires landlords who are selling privately owned properties with three or more units (or any properties that are zoned as such) to first offer their property to local housing nonprofits before they go to the open market. The right of first refusal gives housing nonprofits the right to match the sale price of any of these properties that do make it to market — meaning as long as they are paying market rate, nonprofits will be given priority.

    “We have people that have lived here for generations and who are being priced out of the city because of a massive influx in wealth,” Ian Fregosi told Shareable. “And so we can’t really just sit back and let the market run its course.”

    Fregosi is a legislative aide to San Francisco District 1 Supervisor Sandra Lee Fewer, who authored COPA. The overwhelming support for this act is a consequence of the housing affordability crisis in San Francisco, a city which has seen its stock of affordable housing stagnate in recent years.

    Currently, housing nonprofits are subject to a variety of limitations that make it difficult to compete with cash buyers.

    “In many cases, the nonprofit never gets a chance to really bid on the property because they have to deal with a lot of other factors,” Fregosi explained. “They have to get funding from multiple sources … to be able to make a bid in the first place, for example. These things take time.”

    But COPA shifts this dynamic by requiring sellers to notify a predetermined list of local housing nonprofits before they put their property to market. The act would give the nonprofits five days to respond and then an additional 25 days to make a concrete offer to the property owner, a time window that could make a substantial difference. Proponents of the act hope it will begin to address some of the affordable housing shortages in the city.

    But despite making nonprofits more competitive, COPA leaves a city still gripped by market forces. Sellers are under no obligation to sell their properties to nonprofits, so the latter can still be easily outbid by buyers who have more money.

    A more recent move, also in Washington D.C, is the District Opportunity to Purchase Act (DOPA), which gives the District itself a chance to purchase units if the tenants cannot. DOPA was passed in late 2018, so it’s too soon to know how successful the law will be, but over its forty-year lifespan, TOPA has proven to be a useful tool in combating gentrification in D.C.

    “The D.C. laws are where a lot of the inspiration for COPA came from,” Fregosi said. “It’s a good anti-displacement policy which we actually expanded on by making sure that the properties that are purchased through COPA are permanently removed from the speculative market and preserved as permanently affordable housing.”

    The idea is starting to catch on across the San Francisco Bay. Fregosi has been fielding interest from city representatives and activists in cities including Berkeley and Oakland.

  • The mad, twisted tale of the electric scooter craze
    https://www.cnet.com/news/the-mad-tale-of-the-electric-scooter-craze-with-bird-lime-and-spin-in-san-fran

    Dara Kerr/CNET

    For weeks, I’d been seeing trashed electric scooters on the streets of San Francisco. So I asked a group of friends if any of them had seen people vandalizing the dockless vehicles since they were scattered across the city a couple of months ago.

    The answer was an emphatic “yes.”

    One friend saw a guy walking down the street kicking over every scooter he came across. Another saw a rider pull up to a curb as the handlebars and headset became fully detached. My friend figures someone had messed with the screws or cabling so the scooter would come apart on purpose.

    A scroll through Reddit, Instagram and Twitter showed me photos of scooters — owned by Bird, Lime and Spin — smeared in feces, hanging from trees, hefted into trashcans and tossed into the San Francisco Bay.

    It’s no wonder Lime scooters’ alarm isn’t just a loud beep, but a narc-like battle cry that literally says, “Unlock me to ride, or I’ll call the police.”

    San Francisco’s scooter phenomenon has taken on many names: Scootergeddon, Scooterpocalypse and Scooter Wars. It all started when the three companies spread hundreds of their dockless, rentable e-scooters across city the same week at the end of March — without any warning to local residents or lawmakers.

    Almost instantly, first-time riders began zooming down sidewalks at 15 mph, swerving between pedestrians and ringing the small bells attached to the handlebars. And they left the vehicles wherever they felt like it: scooters cluttered walkways and storefronts, jammed up bike lanes, and blocked bike racks and wheelchair accesses.

    The three companies all say they’re solving a “last-mile” transportation problem, giving commuters an easy and convenient way to zip around the city while helping ease road congestion and smog. They call it the latest in a long line of disruptive businesses that aim to change the way we live.

    The scooters have definitely changed how some people live.

    I learned the Wild West looks friendly compared to scooter land. In San Francisco’s world of these motorized vehicles, there’s backstabbing, tweaker chop shops and intent to harm.

    “The angry people, they were angry,” says Michael Ghadieh, who owns electric bicycle shop, SF Wheels, and has repaired hundreds of the scooters. “People cut cables, flatten tires, they were thrown in the Bay. Someone was out there physically damaging these things.”

    Yikes! Clipped brakes

    SF Wheels is located on a quaint street in a quintessential San Francisco neighborhood. Called Cole Valley, the area is lined with Victorian homes, upscale cafes and views of the city’s famous Mount Sutro. SF Wheels sells and rents electric bicycles for $20 per hour, mostly to tourists who want to see Golden Gate Park on two wheels.

    In March, one of the scooter companies called Ghadieh to tell him they were about to launch in the city and were looking for people to help with repairs. Ghadieh said he was game. He wouldn’t disclose the name of the company because of agreements he signed.

    Now he admits he didn’t quite know what he was getting into.

    Days after the scooter startups dropped their vehicles on an unsuspecting San Francisco, SF Wheels became so crammed with broken scooters that it was hard to walk through the small, tidy shop. Scooters lined the sidewalk outside, filled the doorway and crowded the mechanic’s workspace. The backyard had a heap of scooters nearly six-feet tall, Ghadieh told me.

    His bike techs were so busy that Ghadieh had to hire three more mechanics. SF Wheels was fixing 75 to 100 scooters per day. Ghadieh didn’t say how much the shop was making per scooter fix.

    “The repairs were fast and easy on some and longer on others,” Ghadieh said. “It’d depend on whether it was wear-and-tear or whether it was physically damaged by someone out there, some madman.”

    Some of the scooters, which cost around $500 off the shelf, came in completely vandalized — everything from chopped wires for the controller (aka the brain) to detached handlebars to bent forks. Several even showed up with clipped brake cables.

    I asked Ghadieh if the scooters still work without brakes.

    “It will work, yes,” he said. “It will go forward, but you just cannot stop. Whoever is causing that is making the situation dangerous for some riders.”

    Especially in a city with lots of hills.

    Ghadieh said his crew worked diligently for about six weeks, repairing an estimated 1,000 scooters. But then, about three weeks ago, work dried up. Ghadieh had to lay off the mechanics he’d hired and his shop is back to focusing on electric bicycles.

    “Now, there’s literally nothing,” he said. “There’s a change of face with the company. I’m not exactly sure what happened. … They decided to do it differently.”

    The likely change? The electric scooter company probably decided to outsource repairs to gig workers, rather than rely on agreements with shops.

    That’s gig as in freelancers looking to pick up part-time work, like Uber and Lyft drivers. And like Nick Abouzeid. By day, Abouzeid works in marketing for the startup AngelList. A few weeks ago, he got an email from Bird inviting him to be a scooter mechanic. The message told Abouzeid he could earn $20 for each scooter repair, once he’d completed an online training. He signed up, took the classes and is ready to start.

    “These scooters aren’t complicated. They’re cheap scooters from China,” Abouzeid said. “The repairs are anything from adjusting a brake to fixing a flat tire to adding stickers that have fallen off a Bird.”

    Bird declined to comment specifically on its maintenance program, but its spokesman Kenneth Baer did say, “Bird has a network of trained chargers and mechanics who operate as independent contractors.”

    All of Lime’s mechanics, on the other hand, are part of the company’s operations and maintenance team that repairs the scooters and ensures they’re safe for riders. Spin uses a mix of gig workers and contract mechanics, like what Ghadieh was doing.
    Gaming the system

    Electric scooters are, well, electric. That means they need to be plugged into an outlet for four to five hours before they can transport people, who rent them for $1 plus 15 cents for every minute of riding time.

    Bird, Spin and Lime all partially rely on gig workers to keep their fleets juiced up.

    Each company has a different app that shows scooters with low or dead batteries. Anyone with a driver’s license and car can sign up for the app and become a charger. These drivers roam the streets, picking up scooters and taking them home to be charged.
    img-7477

    “It creates this amazing kind of gig economy,” Bird CEO Travis VanderZanden, who is a former Uber and Lyft executive, told me in April. “It’s kind of like a game of Pokemon Go for them, where they go around and try to find and gobble up as many Birds as they can.”

    Theoretically, all scooters are supposed to be off city streets by nightfall when it’s illegal to ride them. That’s when the chargers are unleashed. To get paid, they have to get the vehicles back out on the street in specified locations before 7 a.m. the next day. Bird supplies the charging cables — only three at a time, but those who’ve been in the business longer can get more cables.

    “I don’t know the fascination with all of these companies using gig workers to charge and repair,” said Harry Campbell, who runs a popular gig worker blog called The Rideshare Guy. “But they’re all in, they’re all doing it.”

    One of the reasons some companies use gig workers is to avoid costs like extra labor, gasoline and electricity. Bird, Spin and Lime have managed to convince investors they’re onto something. Between the three of them they’ve raised $255 million in funding. Bird is rumored to be raising another $150 million from one of Silicon Valley’s top venture capital firms, Sequoia, which could put the company’s value at $1 billion. That’s a lot for an electric scooter disruptor.

    Lime pays $12 to charge each scooter and Spin pays $5; both companies also deploy their own operations teams for charging. Bird has a somewhat different system. It pays anywhere from $5 to $25 to charge its scooters, depending on the city and the location of the dead scooter. The harder the vehicle is to find and the longer it’s been off the radar, the higher the “bounty.”

    Abouzeid, who’s moonlighted as a Bird charger for the past two months, said he’s only found a $25 scooter once.

    “With the $25 ones, they’re like, ’Hey, we think it’s in this location, it’s got 0 percent battery, good luck,’” he said.

    But some chargers have devised a way to game the system. They call it hoarding.

    “They’ll literally go around picking up Birds and putting them in the back of their car,” Campbell said. “And then they wait until the bounties on them go up and up and up.”

    Bird has gotten wise to these tactics. It sent an email to all chargers last week warning them that if it sniffs out this kind of activity, those hoarders will be barred from the app.

    “We feel like this is a big step forward in fixing some of the most painful issues we’ve been hearing,” Bird wrote in the email, which was seen by CNET.

    Tweaker chop shops

    Hoarding and vandalism aren’t the only problems for electric scooter companies. There’s also theft. While the vehicles have GPS tracking, once the battery fully dies they go off the app’s map.

    “Every homeless person has like three scooters now,” Ghadieh said. “They take the brains out, the logos off and they literally hotwire it.”
    img-1134

    I’ve seen scooters stashed at tent cities around San Francisco. Photos of people extracting the batteries have been posted on Twitter and Reddit. Rumor has it the batteries have a resale price of about $50 on the street, but there doesn’t appear to be a huge market for them on eBay or Craigslist, according to my quick survey.

    Bird, Lime and Spin all said trashed and stolen scooters aren’t as big a problem as you’d think. When the companies launch in a new city, they said they tend to see higher theft and vandalism rates but then that calms down.

    “We have received a few reports of theft and vandalism, but that’s the nature of the business,” said Spin co-founder and President Euwyn Poon. “When you have a product that’s available for public consumption, you account for that.”

    Dockless, rentable scooters are now taking over cities across the US — from Denver to Atlanta to Washington, DC. Bird’s scooters are available in at least 10 cities with Scottsdale, Arizona, being the site of its most recent launch.

    Meanwhile, in San Francisco, regulators have been working to get rules in place to make sure riders drive safely and the companies abide by the law.

    New regulations to limit the number of scooters are set to go into effect in the city on June 4. To comply, scooter companies have to clear the streets of all their vehicles while the authorities process their permits. That’s expected to take about a month.

    And just like that, scooters will go out the way they came in — appearing and disappearing from one day to the next — leaving in their wake the chargers, mechanics, vandals and people hotwiring the things to get a free ride around town.

  • À propos des abordages dans la marine états-unienne, le point de vue d’un pilote de la baie de San Francisco (bar pilot)
    gCaptain toujours en pointe sur le sujet…

    The « Navy Way » is the Wrong Course – gCaptain
    http://gcaptain.com/the-navy-way-is-the-wrong-course

    As a retired Lieutenant-Commander in the US Naval Reserve, and a San Francisco bar pilot with over 31 years’ experience, I find the recent collisions of US Navy vessels and the resulting loss of life disheartening and incomprehensible.

    And, much to my dismay, these incidents could have been prevented – that is, if the Navy would stop operating like, well, … the Navy.
    […]
    Today’s Navy seems to have ignored the need to learn the basics of seamanship. One of the first rules of going to sea is relatively simple: if another ship is getting closer and their bearing stays the same, IT WILL HIT YOU. This happened twice in one month! In admiralty law, a ship only has the right-of-way until she reaches extremis, then she must get out of the way or will be found partially to blame. There is no excuse for a modern destroyer not to get out of the way even if it has the right-of-way. Large commercial vessels take miles to stop, but the Navy’s two guided missile destroyers hit midships can maneuver on a dime. I know, because I piloted them.

    Getting hit on your starboard side is a sure sign of not knowing the rules — and what have been the consequences, given the fatalities? In 2007, one of my partners crashed a ship and spilled fuel oil into San Francisco Bay. He went to federal prison for 10 months for killing migratory birds. What is the punishment for officers whose shipmates die due to their lack of knowledge? Did these watch officers get drug tested? Did they go to simulator school? Did they memorize the Rules of the Road? (During one of my reserve tours, the ship’s captain couldn’t believe I knew ALL the rules by heart. Apparently, none of the other Officers of the Deck did.)
    […]
    The Navy culture also relies on the use of many assistants. There are advantages to the system, to be sure, but aboard ship, without one individual “running the show,” the potential for confusion and error increases exponentially. Yet, still, the Navy way continues. During my career, some commanding officers would not give me the “Conn” until their ship got into trouble – and in San Francisco Bay, that potential always existed. When the worse happened, I was quickly requested to take over piloting and straighten out the mess.

    have the Conn, give the Conn, (WP dérive le terme de conduct) en français maritime, l’expression traditionnelle (et impérative !) pour celui qui la reçoit est : je prends la manœuvre. Sujet classique d’éventuelles frictions entre commandant et pilote…

  • India’s Water Politics

    From the San Francisco Bay area to Sao Paulo to Riyadh, water shortages increasingly cloud economic forecasts. But nowhere is the risk greater than in South Asia, where India, the largest economy and most important regional power, faces crippling shortages and a lack of consensus on what to do about them. In turn, water problems threaten to drag down India’s economic growth and slow its rise to regional power. Fortunately, by adopting some common-sense reforms, India’s government can work with the United States and other powers to provide water security for the sub-continent.

  • Atomic Suicide : The Tale of the Sailors and the Seals – RadChick Radiation Research & Mitigation
    https://radchickblog.wordpress.com/2014/01/26/atomic-suicide-the-tale-of-sailors-and-seals


    Article très complet avec une richesse de sources officielles sur les conséquences de l’accident nucléaire de Fukusihima.

    Navy sailor Lindsay Cooper knew something was wrong when billows of metallic-tasting snow began drifting over USS Ronald Reagan. She and scores of crewmates watched a sudden storm blow toward them from the tsunami-torn coast of Fukushima, Japan. Lindsay didn’t know it then, but the snow was caused by the freezing Pacific air mixing with a plume of radioactive steam. “As soon as you step foot on the flight deck and went outside you had this taste of like aluminum foil. We thought that we had felt a plume because there was kind of this warm air that went past the ship and you could kind of tell the differences between jet exhaust — we didn’t have any jets going around at the time. It was like 20 degrees outside and you could feel this warm air and you kind of enjoyed it at first and then you’re like, ‘Is that aluminum foil that I taste?’

    Within about 5 days of those initial plumes, the seals would have had their first taste of aluminium foil, too. Some by direct inhalation, more by what landed in the snow and revolitalized later. What landed in the ocean, quickly worked its way through the food chain. Plutonium, Americium, Uranium, and other highly toxic elements were found a few months later in every single organism tested in Alaskan waters, by the US Department of Energy. That’s extremely bad news if you’re a seal, or anything else that eats seafood from the Pacific. Although the fishing industry, various deceitful news outlets, and paid government scientists seem to want you to believe otherwise.

    The Alaskan Dispatch reported in the Fall of 2011: “Indigenous hunters in Alaska’s Arctic noticed ice seals they rely on for food and other uses covered in oozing sores and losing hair. They were sick and some were dying. As of this month, despite the international group of scientists and researchers the declaration pulled together, no cause has been officially identified for the illness plaguing the ice seals. Walruses and polar bears have turned up with similar ailments. Some of the animals were found to also have bleeding and swelling in their lungs, livers, lymph nodes and other internal organs.

    Meanwhile, Navy personnel began experiencing more severe and mysterious symptoms, including hemorrhaging and cancer. Sebourn, who had been assigned to investigate radiation levels in the air and on American military aircraft, now spends his days going from one specialist to another. After seeing at least 10 doctors and undergoing three MRI’s and two ultrasounds, he still doesn’t know what’s wrong. Sebourn says he very suddenly lost 50 to 60 percent of the power in the right side of his body. This shocked him when he walked into the gym one day and could only do his workout on his left side – he says his right side just didn’t work. Administrative Officer Steven Simmons was on the USS Ronald Reagan too. Simmons suddenly lost 20 to 25 pounds, started running fevers, getting night sweats and tremors, and his lymph nodes started to swell. He can no longer use his legs and spends all of his time in a wheelchair. His weakness has traveled up to his core and arms, and the signals between his brain and his bladder have failed. He uses a catheter every four hours. Other sailors have been diagnosed with immune system failure, blindness and ocular cancers, testicular cancer, lung cancer, colon cancer, and brain cancer.

    “As for the people who are saying those levels weren’t very high, normal background radiation, I call bogus to that, because I was the man taking the background levels. If you think 300 times higher than a normal day’s radiation level is fine, than I don’t know what to tell you” says Seybourn. Over 150 sailors are now part of a class-action lawsuit against TEPCO, for lying about the meltdowns, and the risk to military personnel that were participating in the mission.

    Sea Level Rise Hits Home at NASA
    http://earthobservatory.nasa.gov/Features/NASASeaLevel

    Watching Waters Rise Right Outside the Front Door


    The Sun rises at Kennedy Space Center. The sea is steadily doing the same.
    (Photo by NASA/Andres Adorno)

    In a review of the agency’s vulnerability to sea level rise, NASA’s Climate Adaptation Science Investigators (CASI) Working Group recently wrote:
    Sea level rise of between 13 and 69 centimeters by the 2050s is projected for NASA’s five coastal centers and facilities…Even under lower sea level rise scenarios, the coastal flood event that currently occurs on average once every 10 years is projected to occur approximately 50 percent more often by the 2050s in the Galveston/Johnson Space Center area; 2 to 3 times as often near Langley Research Center and Kennedy Space Center; and 10 times more frequently in the San Francisco Bay/Ames Research Center area. NASA coastal centers that are already at risk of flooding are virtually certain to become more vulnerable in the future.

    These maps show (in red) areas around NASA centers that would be inundated by 12 inches (30 centimeters) of sea level rise. Explore this data using NOAA’s interactive sea level rise and vulnerability tool. (NASA Earth Observatory maps by Joshua Stevens based on data from NASA’s Climate Adaptation Science Investigators Working Group)
    If you think about the height of the sea surface like the height of the water in a calm bathtub, then a rise of a few tens of centimeters over a few decades doesn’t sound like much. But sea level doesn’t rise evenly; it piles up more in some places because of natural wind and current patterns. And turbulence matters: Think about that bathtub with a child sloshing around in it. Waves can roll up one side and then the other, sometimes splashing over the brim. The higher the flat-water line, the greater the chance that the water will slosh out of the basin when it is stirred up by storms and winds.
    Sea level also matters in a horizontal direction. An old rule of thumb is that 1 inch of vertical change in sea level translates into 100 inches of horizontal beach loss on a flat beach or marsh. In this way, a little bit of sea level rise can translate into a lot of water moving inland with storms or abnormally high tides.
    Sea level is important because it gradually moves the high-tide line farther up the beach and closer to buildable land,” said John Jaeger, a coastal geologist from the University of Florida. “It also allows storm surges to penetrate farther inland.

    Launching from a Sandbar
    The high-tide line has been moving landward for some time at Kennedy Space Center on Florida’s east coast. Located within the Merritt Island National Wildlife Refuge and adjacent to Cape Canaveral Air Force Station, NASA’s most famous center covers more than 66 square miles (170 square kilometers) and holds about 20 percent of the agency’s constructed assets. Most of it is built on coastal marshland about 5 to 10 feet above sea level.


    Launch Pad 39B at Kennedy Space Center has been the site of dozens of Apollo era and space shuttle launches. Future SLS and Orion spacecraft will lift off from this site. (NASA)

    Conservative climate models project that the seas off Kennedy will rise 5 to 8 inches by the 2050s, and 9 to 15 inches by the 2080s. If ice sheets in Greenland and Antarctica continue to melt as quickly as current measurements indicate, those numbers could become 21 to 24 inches by the 2050s and 43 to 49 inches by the 2080s.

    We consider sea-level rise and climate change to be urgent,” said Nancy Bray, spaceport integration and services director for Kennedy.

  • Native American Activists Occupy Alcatraz Island, 45 Years Ago — History in the Headlines
    http://www.history.com/news/native-american-activists-occupy-alcatraz-island-45-years-ago

    Shortly before dawn on November 20, 1969, 89 American Indians boarded boats in Sausalito, California, and made a five-mile trip across foggy San Francisco Bay to #Alcatraz Island. Upon landing, they declared the former prison Indian land “by right of discovery” and demanded the U.S. government provide funding to turn it into a Native American cultural center and university. When their terms were ignored, the activists spent more than 19 months occupying the island in defiance of the authorities. Federal officials finally removed the last of the protestors from “the Rock” in June 1971, but not before the occupation had started a national dialogue about the plight of American Indians.
