TIMING IS EVERYTHING
New Floating Fire Station Makes the Move with Clockwork Precision
The San Francisco Fire Department’s new floating fireboat station started to come to life in early 2019 some 6,100 miles away in Nantong, China, an industrial port city north of Shanghai located on the bank of the Yangtze River.
There, the steel barge that serves as the foundation of the fire station was manufactured. It then traveled across the Pacific last winter to Pier 1 on Treasure Island in the middle of San Francisco Bay.
After its arrival in January, construction began on the two-story fire station. Mooring lines kept the float in place on the Bay waters just off the Treasure Island shore.
Fast forward 11 months: With work complete on the 14,900-square-foot building, it was time to make the final move.
Just after midnight on that early Thursday morning, crews untethered the mooring lines from the holds on Treasure Island and attached the float to two tugboats, which guided the float to Pier 22 ½.
The timing seemed perfect: The Bay was in a period of slack tide when the water is void of powerful waves and current. But just as they were getting underway, the tugboat captain picked up a GPS reading that showed a massive container ship passing under the Bay Bridge and heading in their direction. The move was paused briefly until the ship had passed.
Their route, a distance of 2.88 nautical miles, took a little more than an hour. They encountered no obstacles along the way – no hidden sandbars nor humpback whales. “It was very smooth,” said William Knudson, a civil engineer who oversaw the highly choreographed operation as a project manager with Power Engineering Construction Co.
Arriving at Pier 22 ½, they were met by two push boats, on hand for what would be the most exacting part of the operation. There was very little room for error. The float, 173 feet long and 95 feet wide and weighing 3.3 million pounds, had to fit between four mooring piles that will hold the structure in place, with just four inches to spare on either side.
A tugboat pilot stood atop the float up front, and with everyone involved tuned to the same channel on the marine radio, he gave orders – move a little this way, a little that way, and this way again. Only he used maritime-speak as he made the directional commands needed to squeeze the float into place. The pre-work measuring and re-measuring the footprint between the four piles and the float itself didn’t disappoint – a perfect fit.
With sunrise still nearly five hours away, crews hustled to secure the float. They used a crane to position four massive steel collars weighing 10,000 pounds apiece that connect the float to the piles. Forty 1 ¼-inch bolts attached each collar.
The steel piles, at 125 feet long and 60 inches in diameter, were set in place in early fall. A crane hoisted them vertically into the water, where they sank about 50 feet into the Bay mud, just by their sheer weight. Then, a mechanized vibratory hammer weighing 70,000 pounds drove them down deeper, a third of an inch at a time with each cycle. Two of the piles are anchored in 90 feet of dense Bay mud; the other two in 90 feet of thick mud and bedrock. A specially trained crew of pile drivers hammered each pile into place. Boring samples taken two years ago determined their exact location and depth.
Six months before specialized crews transported San Francisco’s new floating fireboat station across the Bay from Treasure Island to Pier 22½, just north of the Bay Bridge, the project team plotted the optimal day and time. The decision? Just past midnight on Dec. 3.
“We knew we wanted to do it at night when the wind and waves are at minimum and there’s less boat traffic on the Bay,” said Knudson, who rode in a small skiff alongside the floating fireboat station as it traveled to its permanent home.
As a bonus, the waning moon – just one day past full – provided plenty of ambient light for the overnight move.
San Francisco’s new floating fire station is thought to be the only structure of its kind in the world.
Once the utilities are hooked up and the finishing work and inspections are complete, the building will replace the Fire Department’s existing Fireboat Station 35 – located on dockside and serving the City’s waterfront since 1915. A designated City landmark, the historic building has been deemed too small and outdated to adequately serve modern-day San Francisco. It also doesn’t meet today’s seismic-safety codes and could be at risk of flooding due to sea level rise.
One of the biggest advantages of the floating fire station is that it was designed to rise and fall with the natural tide of the Bay, king tides and future sea level rise that is projected due to global warming.
The Station 35 crew is scheduled to move into their new digs this coming spring. The planning phase of the project began in 2016.
As for the old fireboat station, it will house a fire engine and also be used to store equipment. The San Francisco Fire Department's three fireboats and rescue watercraft will be berthed at the new floating facility. Community members will have access to a new waterfront observation deck being built on the south side of the station.
The $39.9 million project is funded by the second phase of the Earthquake Safety and Emergency Response (ESER) Bond, which passed with 79 percent approval of San Francisco voters in June 2014. The first phase of the bond program passed in 2010 and a third phase in 2020, both with overwhelming support.
Swinerton-Power (the joint venture of Swinerton and Power Engineering Construction Co.), constructed the design-build project. Shah Kawasaki Architects provided the building design, and Liftech Consultants Inc. provided the marine design/barge. The San Francisco Public Works Building Design and Construction Division is managing the project on behalf of the San Francisco Fire Department.

Going Deep with Deep Cleaning
Armed with a sharp hand tool to dig out weeds from sidewalk cracks and between the gutter and curb,
Jamir Nathan moved along a North Beach block inch by inch scraping away unwanted plants the size of a fingernail. “You’ve got to really go after them and get the dirt they’re growing in between the cracks,” he said. “You can’t just leave a little because they’ll grow back.”
Around the corner from Nathan, Tommy Lam used a power washer to scour away a thin film of soot covering the bright yellow curb ramp. Down the block from them, Yizheng Yu painted over graffiti tags marring a lamppost and Mark Simmons swept up leaves and litter.
Nathan, Lam, Yu and Simmons worked along Grant Avenue in North Beach on Dec. 10 as part of the CleanCorridorsSF team. The special operation deploys a large contingent of San Francisco Public Works street cleaners to a different neighborhood commercial district every Thursday morning to power wash and sweep the sidewalks, flush down the roadway and wipe out graffiti – a coordinated deep-cleaning blitz resulting in noticeable improvements to the cleanliness of the targeted area.

Coming Soon: Treecycle 2021!
Disposing of your Christmas tree might not be the most enjoyable holiday tradition, but thanks to Public Works and our partners at SF Environment and Recology, it doesn’t have to be a major inconvenience either.
For the last 34 years, we’ve been holding an annual “Chipping of the Trees” – a post-holiday operation that turns unadorned Christmas trees into earth-friendly mulch.
From Jan. 4 through Jan. 15, Recology will be collecting trees for recycling throughout San Francisco. All you need to do is place your tree on the curb next to your bins the night before your regularly scheduled collection day and Recology will take care of the rest.
Before you take your tree out, please make sure you've taken off all lights and ornaments, and do not cover or wrap your tree in plastic. If your tree is over 6 feet tall, please cut it in half or we will not be able to take it away.
What happens after we pick up the trees? They’re sent through a woodchipper and repurposed as mulch, which then is used to provide nutrients to soil and prevent weed growth in parks around the City. The 500 tons of trees collected each year through this program create more than enough mulch to go around.
Tree recycling is part of our “Love Our City” campaign that encourages everyone in San Francisco to pitch in to help keep San Francisco clean and looking beautiful. Even little things, like setting out your Christmas tree on your regularly scheduled collection day, will help us keep our streets and sidewalks safe and clean!
Focus on Chinatown Shows Benefits of Teamwork
Early morning on Stockton Street, the main commercial corridor in Chinatown, bursts with life:
Pallets of deliveries await being brought inside the stores; merchants set up merchandise displays on the sidewalk with the hope of a profitable day; early-bird shoppers pick out fresh produce from newly opened boxes.
Unfortunately, there are times when the bustle of business creates problems: blocked paths of travel, making it hard for people on foot to navigate safely along the sidewalk; and unsightly garbage that wasn’t disposed of properly, blemishing the cleanliness of the historic neighborhood.
Some local merchants brought their concerns to us and asked for assistance. Our response: Of course!
On Dec. 9, a Public Works team with representatives from our street cleaning, inspections and community engagement bureaus conducted a merchant walk in Chinatown to speak with business owners about their responsibilities of keeping this vibrant neighborhood clean, safe and pleasant for everyone.
Team Public Works started the merchant walk at 8 o’clock in the morning and focused on illegal dumping, unlawful sidewalk sales, graffiti and overflowing blue, black and green refuse bins. The goal of the visit was to help merchants better understand the laws they must comply with to keep public areas safe and clean, which in turn will help businesses thrive by creating a more welcoming shopping district.
As our employees went door to door, patrons stopped to thank them for being there. Business owners cooperated with our staff and made immediate corrections to comply with the health and safety codes. We have more merchant walks coming up and we’re preparing to conduct stakeouts to catch people who leave behind illegal dumping, including cardboard. Meanwhile, our dedicated street cleaning crews will continue their daily runs through Chinatown.
All of us need to work together to care for our neighborhoods. The benefits are worth it!
Despite San Francisco’s moderate climate, its winter storms can wreak major havoc on the public right of way.
The heavy rain and high winds can cause flooding, downed trees, potholes and sewer backups, all of which pose health and safety threats to the community. This is why Public Works has developed a comprehensive approach to storm preparation and response that draws from the expertise of staff from across the department.
Many of these efforts take place well before storms even enter the forecast, as the City’s trees and roads need regular maintenance throughout the year to withstand the winter elements. Our Engineering Division constantly studies and collects data on the City’s flood-prone areas in an effort to limit flooding and related damage.
Similarly, the Bureau of Urban Forestry maintains San Francisco’s street trees, preparing them for harsh weather by keeping them trimmed to minimize branch failure during high winds. Our Bureau of Street and Sewer Repair even distributes sandbags free of charge each winter to San Franciscans whose homes and businesses are susceptible to flooding.
When a downpour begins to hit, our Bureau of Street Environmental Services crews jump into action, acting as first responders to 311 calls reporting fallen trees, localized flooding or manhole covers displaced by overflowing storm drains and flooding. Once these crews assess the situation, they either handle it themselves or call on our Bureau of Urban Forestry arborists if the job involves fully downed trees or massive limbs. Storm-related damage to City streets can emerge weeks after the fact. This is where the Bureau of Street and Sewer Repair comes in.
Their crews diligently fill potholes and pavement cracks that occur when the soil beneath roadways becomes saturated with rainwater. Crews also respond to sinkholes.
Want to learn more about these efforts? Watch the newest installment of SnapshotsLive!, Public Works’ new webinar series, to get the inside scoop. This month, we got the rundown on storm response from Urban Forestry’s Superintendent Carla Short, hydraulics engineer Bimayendra Shrestha, Street and Environmental Services Superintendent Peter Lau and Matt Naclerio, who heads the Bureau of Street and Sewer Repair.
Virtual Ceremony Marks Construction Milestone for New SOUTHEAST Community Center
There’s a ritual in the world of building construction known as the topping out ceremony.
In normal times, the milestone event draws construction workers, dignitaries, community leaders and the project team to cheer as the final steel beam is placed atop the structure – officially marking completion of the building’s steel framing. The beam, hoisted by crane, usually sports an American flag at one end and a small evergreen tree on the other.
But this year is no ordinary time, with the COVID-19 pandemic upending most everything. So instead of hosting a topping out celebration in person, the project team behind the City’s new Southeast Community Facility, now under construction in the Bayview, noted the occasion with a virtual event. Hundreds of people viewed the speeches and beam-raising online.
The new Southeast Community Facility, owned and operated by the San Francisco Public Utilities Commission (SFPUC), will sport a large, state-of-the-art special events space and multi-purpose space for meetings, events, dance classes, community gatherings and daycare services. There also will be coworking space for community organizations, a meditation garden and a playground.
The three-story, 45,000-square-foot structure at 1550 Evans Ave. in the Bayview is set to open next year. It will replace the current community center at 1800 Oakdale Ave., which was built in the 1980s to mitigate the environmental and social impacts of the SFPUC’s sewage treatment plant’s expansion in the neighborhood.
Public Works is a key partner in the replacement project, providing architecture, landscape architecture, construction management, mechanical engineering, electrical engineering, structural engineering and hydraulic engineering services. Our site assessment and remediation and permitting teams also have been involved. It’s an exciting undertaking that will serve the neighborhood for generations.
Let’s hope that by the time the ribbon-cutting rolls around, the COVID-19 pandemic will be under better control and we can celebrate its grand opening in person.
A Look Back at 2020
The COVID-19 pandemic seared a devastating brand onto 2020 that will not be removed: Nearly 1.7 million deaths worldwide, including more than 300,000 in the United States, and more to come. Tens of millions more people testing positive for the virus. A broken economy with job loss, shuttered businesses and loss of income and revenue. Family gatherings, community celebrations, travel and in-school learning curtailed. The ravages are real and still unfolding.
But the year also showed us human compassion, ingenuity, resourcefulness, resiliency and hope.
At the onset of the pandemic in the spring, San Francisco Public Works embraced the mantra for our staff and the communities we serve: We will get through this, together. And we have been doing just that.
Our employees, all deemed essential workers, have been on the job throughout the health crisis, whether working on COVID-response initiatives, such as developing safe sleeping sites for San Francisco’s unhoused residents and readying COVID testing sites, or advancing our core work, such as cleaning streets, paving roads, pruning trees, issuing street-use permits and designing and managing the City’s capital projects.
The annual Year in Review feature in our In the Works digital journal captures a representative look at our work in 2020. Please take a look.
