Comments Off on Meet the urban planner responsible for San Francisco’s car-free Market Street

Downtown San Francisco is putting pedestrians first by turning the 2-mile Market Street, a major hub for the city, into a completely car-free space. Inhabitat spoke with an urban planner of the esteemed Perkins and Will for more details about the groundbreaking, pedestrian-friendly project. While the complete redesign is expected to extend into the rest of the year, January 29 marked the official ban of cars on the thoroughfare. The structural transformation will include a restriction of public cars, but it will also implement newer two-way streets, intersection safety improvements and extensions for the Muni (the city’s public transit system). Buses, as well as a fleet of vintage streetcars, will also be able to operate along the street. Related: Perkins and Will designs modular, affordable housing for the homeless Inhabitat caught up with urban planner and developer Geeti Silwal from the San Francisco branch of design firm Perkins and Will . Silwal was an integral part of the design and development of the Market Street project. Her initial design created the vision and laid the foundation for the car-free initiative, taking close to a decade to finally come to pass. Inhabitat: The plan to make San Francisco’s Market Street car-free was 10 years in the making. Can you talk a bit about how this project began? Silwal: The project was initiated primarily to take advantage of the fact that Market Street needed to replace its aging utility that would need to be dug up soon. The city agencies took this opportunity to reimagine the role and identity of the city’s premiere boulevard. Working with six key city and county agencies, Perkins and Will led a team of urban designers, transportation planners, infrastructure engineers, public realm strategists, streetscape designers and wayfinding experts to lead this exploration. We started in 2011 meeting three demanding — and sometimes competing — objectives: placemaking, enhancing transit experience and improving infrastructure. In order to meet these objectives, we expanded the scope of the study to include Mission Street to help relieve the demands on Market Street. We analyzed: What if Market Street offered seamless transit transfers and relied on Mission Street to provide safe, pleasant, dedicated and buffered bike lanes? What if we minimized space dedicated to private vehicles to provide more space for pedestrians and bicyclists ? What is the right bike infrastructure to invite the 8- to 80-year-olds to ride on Market Street? Would this achieve our shared vision of Market Street as a destination to socialize and enjoy street life and to interact with public art , nature and each other?  We saw this as a once-in-a-lifetime opportunity to create a beautiful street befitting the world-class city it represented. Prioritizing and structuring the street for people and public life over movement of private vehicles was a fundamental goal that the entire team got behind. Inhabitat: How do you feel now that this vision has come to life? Silwal: It’s gratifying. If you were to walk Market Street today and compare it to walking it the week before it went car-free , you’d notice a dramatic difference. Market Street now feels peaceful, safe and comfortable — it really feels like a completely different place. There has been a positive response from the media and people in general. We’ve heard many people say, “I took transit and it was so fast and so much better!” or “I biked Market Street and it feels as though I am in Amsterdam.” And this is only the beginning. More improvements will happen in the next few years as the future phases of the Better Market Street project unfold. Inhabitat: What do you think banning cars on some of San Francisco’s streets means for the rest of the country? Are there many other environmentally minded cities following suit? Silwal: The Better Market Street project was inspired by several cities in Europe, which have streets prioritized for pedestrians, cyclists and transit. There are many examples outside of Europe as well. I come from India, and in my home city, Shimla, the main streets in the mall and lower mall area are closed to traffic and are for pedestrian use only. We need to embrace the qualities of these streets that put ‘people first’. Market Street’s new image will be instrumental in inspiring other cities to rethink their streets. It will take strong political will, persistent public agency collaboration, community support and individual behavioral change to think beyond cars. Inhabitat: What about the design do you think was most integral to the environmental benefits of the project? Silwal: By not enabling private vehicles, people are encouraged to use low-carbon modes of transportation and subsequently, greenhouse gas emissions are dramatically reduced. By making Market Street safe, inviting, comfortable and efficient for pedestrians, cyclists and public transit users, people are more likely to take these modes of transit. Related: Car-free Sundays are the norm in Colombia’s capital city, Bogotá Inhabitat: We love your motto — Designing urban centers with the fundamental organizing principle of ‘people first’ creates more humane, inclusive and socially connected cities . What is important about putting pedestrians first in the fight against climate change? Silwal: We’re in a climate crisis , and we need to base our urban planning around it. Transportation is the biggest contributor to greenhouse gas emissions. By prioritizing cars, we have structured our streets to promote that. If we design streets for the low-carbon modes, we will have a different outcome. I would say that ‘pedestrians first’ is fundamentally about a ‘people first’ approach. Designing cities that allow the majority of people to navigate their city on foot, bike or transit will result in a huge reduction in carbon emissions. Providing an efficient, enjoyable and a robust network of transit system reduces single-occupancy car trips.  We know that climate change impacts will have a more severe effect on the most vulnerable population of our cities. Planning for physical and social connectedness is an important criterion in dealing with climate change. Social connectedness that is about face-to-face interaction enables people to know, understand and empathize more with their fellow beings. It facilitates social resilience. A resilient city is better prepared to fight climate change. Inhabitat: Can you talk about safety, which was the other big concern before Market Street’s car ban went into effect? Silwal: Market Street has always been a popular street for the cyclist community, but it is also infamous for 20 times more collisions than similar streets in the state. Reducing conflict among pedestrians, cyclists and drivers was a key goal for this project. This change will make it much safer for commuting pedestrians and cyclists. Further enhancements to the bike infrastructure will be rolled out in future phases of the Better Market Street project that will have a dedicated and buffered environment for cyclists — making it even safer. Inhabitat: What’s next for you? Can we look forward to any other exciting sustainability projects in the future? Silwal: Through our urban design practice, Perkins and Will is continually planning, advocating and proposing for pedestrian/bike-prioritized connectivity in existing environments and new developments. Mission Rock is a project along San Francisco’s eastern waterfront on the Giants’ 25-acre surface parking lot. Mission Rock’s Shared Public Way will offer a new street prioritized for pedestrians, with limited vehicle movement. The Shared Public Way at Mission Rock will be a dynamic space with street rooms, stormwater gardens and tree groves that will create a lively and unique environment. These design elements serve as cues to differentiate pedestrian-dedicated areas from the shared pedestrian/vehicular zone. Vehicles on the Shared Public Way will be limited to one-way travel for drop-off, pickup and deliveries only. Besides streets, Perkins and Will is currently engaged in the Living Community Challenge (LCC) pilot project in the city of Sacramento called the Sacramento Valley Station Master Plan. “LCC is a certification program that guides the design and construction of buildings and neighborhoods to be socially just, culturally rich and ecologically restorative. LCC projects aim to have a net-positive impact in seven petals: place, water, energy, health & happiness, materials, equity and beauty.” This project plans to be a regenerative project. It plans to be a net-positive carbon, net-positive water and net-positive energy community around the regional intermodal mobility hub in Sacramento. We are privileged to work in an industry that lays the foundation for smarter, sustainable design that has a positive impact on the places and people that inhabit it. + Perkins and Will Images via Perkins and Will

Craft beer waste saves Montana town $1M for wastewater treatment

Comments Off on Craft beer waste saves Montana town $1M for wastewater treatment

A Montana town has found a money-saving solution to its sewage and wastewater treatment expenses, thanks to a nearby craft brewery. The innovation caught the eye of the Environmental Protection Agency (EPA), which provided the town and its water reclamation facility an Honorable Mention accolade in one of the federal agency’s annual awards. Havre, Montana has a population of 10,000. Its 40-year-old water reclamation facility, as the EPA has described, “needed upgrades to help meet their final ammonia and residual chlorine limits,” while processing more than 6 million gallons of water . Related: EWG warns ‘forever chemicals’ are contaminating US drinking water at levels far worse than expected Unfortunately, with more than 10 breweries nearby, the wastewater generated further increased because beer waste is “rich in yeast, hops and sugar.” These contents are known to skew the microbial activity process that removes both nitrogen and phosphorus from the water as it is being treated. In short, if nitrogen and phosphorus are not removed before the treated water enters the drain-off into estuaries, then bacterial and algal blooms will arise. These unwanted blooms would disturb an estuary’s water chemistry enough to adversely affect the ecosystem. Engineering consultant Coralyn Revis offered a paradigm shift to solve the issue. “If we can use [brewery waste] correctly and put it in the right spot, it’s very beneficial to the process,” Revis said. “This is super-simplified, but like, if they’re eating their french fries, they need a little ketchup with it. So to get the nitrate out, you dose a little carbon, and the bugs are happier.” Havre’s wastewater plant manager, Drue Newfield, sought Michael Garrity, Triple Dog Brewing Company’s owner, to source leftover barley for feeding the water treatment microbes. The spent barley was used as a substitute for the chemical alum, an aluminum-sulfate solution. The joint endeavor saved the community from investing an additional $1 million in upgrades to the water treatment plant. “To further enhance the biological phosphorus removal process, 10 gallons of waste barley mash from a local brewery gets added daily as an external source of carbon and volatile fatty acid supplement,” the EPA explained. “These improvements have allowed the facility to continuously meet all permit effluent limits and has significantly improved the operability, reliability and treatment capability of the facility. These upgrades have greatly improved the quality of wastewater effluent discharged to the Milk River, particularly with respect to nutrient levels and ammonia toxicity.” The endeavor has been federally acknowledged as a creative and successful example for integrating community involvement at solving water quality infrastructure challenges in four key areas: public health, economy, sustainability and innovation.
