Construction Begins on Pedestrian-Friendly Redesign of Fisherman’s Wharf

Crews began work yesterday on an overhaul of Jefferson Street in Fisherman’s Wharf that will expand pedestrian space, reduce the number of cars, and create a more welcoming public realm for the throngs of tourists that regularly crowd the street. Improvements on the first two blocks of Jefferson, between Jones and Hyde Streets, were fast-tracked for completion in time for America’s Cup, which is set to begin on July 4. Construction was originally scheduled to begin in October, but it was pushed back to January for unspecified reasons.

The project, designed with the help of Danish architect Jan Gehl, is expected to transform Jefferson into the kind of popular pedestrian-oriented streets that are found many in cities across the world, but are few and far between in San Francisco, as the San Francisco Business Times noted back in June:

The remade Fisherman’s Wharf will recall — but not try to copy — other noted areas where strolling and biking are the main way to get around a shopping/eating district, like Santa Monica’s Third Street Promenade or Miami Beach’s Lincoln Road.

“It’s not being done to make it like Disneyland,” said Troy Campbell, executive director of the Fisherman’s Wharf Community Benefit District. It was important to shopkeepers and other longtime residents of the area that Fisherman’s Wharf maintain its character, Campbell said.

“On a busy day, it should feel like an outdoor plaza, an urban living space,” said Neil Hrushowy, project manager in the city’s Planning Department.

New Ordinance Streamlines Conversion of Gas Stations to Ped-Friendly Uses

The SF Board of Supervisors today approved changes to the city’s planning code to make it easier for developers to convert gas stations to uses like apartments and storefronts on major transit and pedestrian streets.

“Gas stations have a lot of [drivers] coming in and out, and they can slow down transit,” said Judson True, an aide to Supervisor David Chiu, at a hearing of the Land Use and Economic Development Committee last week. “In a transit-first city, while we want to make sure there are some gas stations, on primary transit corridors, this allows them to be converted under certain parameters without a Conditional Use authorization.”

By removing the hurdle of obtaining a Conditional Use permit — an exemption from local planning regulations — the amendment is intended “to balance the desire to retain [gas stations] with city policies which support walking, cycling, and public transportation, and which encourage new jobs and housing to be located in transit corridors,” according to the Board of Supes’ summary of the bill [PDF].

In addition to attracting car traffic that often blocks transit, bike lanes, and sidewalks, gas stations are voids in the urban fabric that degrade the pedestrian environment. On a block of Divisadero Street between Fell and Oak Streets, which is packed with three gas stations, street safety advocates held protests in 2010 calling for the closure of a driveway at an Arco gas station where drivers regularly block the bike lane on Fell. The situation improved somewhat after the SFMTA painted the bike lane green and removed parking spaces to create a longer queuing space. Though major street improvements are planned for Fell and Oak, the Arco entrance would remain mostly as it is, and it’s unclear whether these routes would be considered primary transit or pedestrian streets.

The ordinance, which also includes a provision expanding the enforceable bike parking requirements within buildings, is part of a larger effort underway by Livable City and Supervisor Chiu to reform myriad aspects of the city’s planning code. Stay tuned for more coverage of this ongoing campaign.

From Minneapolis: Ten Street Design Solutions to Transform Your City

Minneapolis has dozens of miles of off-street facilities.

Only 11 cities in the U.S. have earned the title of Gold-Level Bicycle Friendly Community from the League of American Bicyclists. In May, Minneapolis joined the select ranks and, last week, the city got a chance to show off its bike progress to a national audience of active transportation advocates and officials.

When Mayor R.T. Rybak took the stage at the Safe Routes to School National Conference, he made it clear that Minneapolis is gunning for Portland, aiming to be the best biking city in the nation. Not surprisingly, many of the 600 attendees were eager to see the anatomy of a gold-level bicycle friendly city firsthand.

The city’s rise is thanks, in part, to the Non-Motorized Transportation Pilot Project, a program created by the last federal transportation bill that put $25 million in the coffers of four cities to increase bicycling through infrastructure improvements. To showcase the innovations spurred by those dollars, in Minneapolis, Shaun Murphy, the city’s non-motorized transportation coordinator, and Steve Clark, walking and bicycling program manager for Transit for Livable Communities, took Safe Routes participants on a bike tour of some of the completed and in-progress projects.

Drawing largely from Clark’s cheat sheet, here are the “10 Design Solutions that Can Transform your City.”

Alex Steffen: We Can’t Avert Climate Change Without Dense Cities

Alex Steffen goes by the title “planetary futurist,” which makes me realize I should probably spruce up my title to something that makes me sound like I should be wearing a cape, too. What he does is write about sustainable cities, on WorldChanging.com for seven years and more recently in his book, Carbon Zero.

He just gave a TED talk about how to make cities more sustainable. And while he’s primarily looking at climate impacts, he pretty conclusively dismissed the notion that the problem can be solved with clean fuels.

“We tend to seek simple answers,” he said. And if we assume the problem is fossil fuels, he said, “the answer must be to replace fossil fuels with clean sources of energy. And while we do need clean energy, I would put to you that by looking at climate change as a clean energy generation problem, we’re setting ourselves up not to solve it.”

With a rapidly urbanizing planet and eight billion people projected to live in or near cities by midcentury, Steffen asserts that it may just not be possible to generate enough energy to power all those cities – if those cities continue to look like the ones in the developed world today, anyway. The solution, he said, is density.

Editor’s note: Streetsblog San Francisco is thrilled to launch a three-part series today by renowned Danish architect and livable streets luminary Jan Gehl. The pieces are excerpts are from his book, “Cities for People” published by Island Press. Donate to Streetsblog SF and you’ll qualify to win a copy of the book, courtesy of Island Press. Visit the Island Press website to find many more great titles by the nation’s leading publisher of books on environmental issues.

Feeling safe is crucial if we hope to have people embrace city space. In general, life and people themselves make the city more inviting and safe in terms of both experienced and perceived security.

In this section we deal with the safe city issue with the goal of ensuring good cities by inviting walking, biking and staying. Our discussion will focus on two important sectors where targeted efforts can satisfy the requirement for safety in city space: traffic safety and crime prevention.

Throughout the entire period of car encroachment, cities have tried to remove bicycle traffic from their streets. The risk of accident to pedestrians and bicyclists has been great throughout the rise in car traffic, and the fear of accident even greater.

Many European countries and North America experienced the car invasion early on and have watched city quality deteriorate year by year. There have been numerous counter reactions and an incipient development of new traffic planning principles in response. In other countries whose economies have developed more slowly and modestly, cars have only begun to invade cities more recently. In every case the result is a dramatic worsening of conditions for pedestrians and bicycle traffic.

Searching for Market Street’s True Identity

San Franciscans are dreaming big as Market Street’s transformation approaches in 2015, when the city’s most important street is scheduled to be redesigned and repaved. City planners are engaging with citizens to answer a century-old question: How can we make Market Street the glorious thoroughfare that it needs to be?

Better Market Street, a collaborative project of five city agencies, has held public meetings and webinars the past two weeks to field input from people who walk, bike, ride transit, and even drive along the street. The effort is being informed by a large swath of research brought to the table by city staffers, which is now available on the Better Market Street website.

“Market Street is San Francisco’s civic backbone, connecting water to hills, businesses to neighborhoods, cultural centers to recreational opportunities,” the site’s about page states. “The movement of people and goods, from the very earliest times, has dominated its design and use. But Market Street needs to be more than a transportation route. It needs to be the city’s most vibrant public space and many San Franciscans feel it falls far short of this ideal.”

Block-by-block, hour-by-hour data documenting the urban environment were collected by researchers to help inform input from attendees at recent workshops. Researchers note everything from fluctuations in pedestrian and bicycle traffic along the street, to the conditions plaguing its extremely high volume of transit trips, to the placement of trees and how the usage of plazas is impacted by the sun and wind. Comparisons and best practices from major streets abroad help put it all in perspective.

Transit: The Greenest Technology

The most important community-scale system dependent on urbanism is transit. It has long been known that density and transit ridership are linked, but it goes much deeper than that. The key to viable transit systems is not just density but walkability and mixed use—true urban places. If people cannot walk the quarter mile to or from a station, chances are they will not use the transit. Conversely, if they can easily run errands and coordinate trips on the way to or from a station, they are more likely to use transit. European data show that the percentage of walk or bike trips always exceeds that of transit trips—often by more than two to one.27 In fact, walking by itself constitutes 30 percent of all trips in Great Britain (versus 9 percent transit), and in Sweden walk/bike trips are 34 percent of the total (versus 11 percent transit). 28 Transit supports and extends the pedestrian environment; transit is pedestrian dependent, not the other way around. The primary alternative to the car and all of its environmental costs is the pedestrian environment and the walkable urbanism that supports transit.

A good transit system has many layers, from local buses to bus rapid transit and streetcars, from light rail to subways and commuter trains. They all feed into and reinforce one another, and they all depend on walkable urbanism at the origin and destination. The quality of the interface from walking to transit, and from one form of transit to the other, is central to displacing car trips and is the greenest technology that urbanism provides.

The relationship among transit, urbanism, travel behavior, and carbon emissions is complex but can be summarized with one key quantifiable metric, vehicle miles traveled (VMT)—effectively, the amount we drive. VMT is determined by the number and distance of trips we take, and our “mode split”—the percentage of trips taken by various transportation modes such as walk, bike, car, carpool, or transit. Each household, depending on its location, income, and size, has an average VMT per year, which when combined with various auto technologies will generate its travel carbon footprint.

Urbanism in the Age of Climate Change: Green Technology

Editor’s note: This week, we continue our 5-part series of excerpts from Peter Calthorpe’s book, “Urbanism in the Age of Climate Change.” This is installment number four. Thanks to Island Press, a few lucky Streetsblog readers will be selected to receive a free copy of the book. To enter the contest, fill out this form.

I was part of the passive solar architectural movement in the 1970s. Its core idea was to provide energy for buildings in the most direct, elegant way. We had disdain for complicated “active solar” systems, with their complex engineering, maintenance, and costs. The passive way was first to reduce the demands by building tight, well insulated structures, flooded with natural light, and then to let the sun’s radiation or the cool night air work with the buildings’ form to provide thermal comfort. The same approach needs to be taken in relation to the climate change challenge: we need to find the simple, elegant solutions that are based on conservation before we introduce complex technology, even if it is green.

We need to focus, ironically, on ends, not means. For example, in passive solar buildings, focusing on the end goal (thermal comfort) rather than the means (heating air) changed the design approach dramatically. It turns out that human comfort has more to do with surrounding surface temperatures than with air temperature in a building, so massive walls that absorb and store the sun’s gentle heat also provide a more comfortable environment without all the hot air. Or, if lighting is the goal, electricity and bulbs are just one potential means; a building that welcomes daylight is the simple, elegant solution—even better than a complex system of wind farms generating green electrons for efficient fixtures. Likewise, the goal of transportation is access, not movement or mobility per se; movement is a means, not the end. So, bringing destinations closer together is a simpler, more elegant solution than assembling a new fleet of electric cars and the acres of solar collectors needed to power them. Call it “passive urbanism.”

Once demands are reduced by passive urbanism, the next step is to add technology. Green urbanism is what you get when you combine the best of traditional urbanism with renewable energy sources, advanced conservation techniques, new green technologies, and integrated services and utilities. All the inherent benefits of urbanism can be amplified by a new generation of ecological design, smart grids, climate-responsive buildings, low-carbon or electric cars, and next generation transit systems.

Urbanism in the Age of Climate Change: Urbanism Expanded

Image © Peter Calthorpe & Marianna Leuschel

Editor’s note: This week, we continue our 5-part series of excerpts from Peter Calthorpe’s book, “Urbanism in the Age of Climate Change.” This is installment number three. Thanks to Island Press, a few lucky Streetsblog readers will be selected to receive a free copy of the book. To enter the contest, fill out this form.

For many people, urban is a bad word that implies crime, congestion, poverty, and crowding. For them, it represents an environment that moves people away from a healthy connection with nature and the land. Its stereotype is the American ghetto, a crime-ridden concrete jungle that simultaneously destroys land, community, and human potential. The reaction to this stereotype has been a middle-class retreat into the closeted world of single-family lots and gated subdivisions in the suburbs. As a result, much of the last half century’s planning has been directed toward depopulating cities, whether through the satellite towns of Europe or the suburbs of America.

But, for many others, the word urban represents economic opportunity, culture, vitality, innovation, and community. This positive reading is now manifest in the revitalized centers of many of our historic cities. In these core areas, the public domain—with its parks, walkable streets, commercial centers, arts, and institutions—is once again becoming rich and vibrant, valued and desirable. There is new life in many city centers and their public places, from cafés and plazas to urban parks and museums—ultimately drawing people back to the city.

In fact, since 2000, many of our major cities have increased their share of new home construction while their region’s suburbs have declined. For example, in 2008, Portland issued 38 percent of all the building permits within its region, compared to an average of 9 percent in the early 1990s; Denver accounted for 32 percent, up from 5 percent; and Sacramento accounted for 27 percent, up from 9 percent. There is an even stronger trend toward urban redevelopment in the largest metropolitan regions. New York City accounted for 63 percent of the building permits issued within its region. By comparison, the city averaged about 15 percent of regional building permits during the early 1990s. Similarly, Chicago now accounts for 45 percent of the building permits within its region, up from just 7 percent in the early 1990s.13 This represents a dramatic turnaround as cities regain their roles as centers of innovation, social mobility, artistic creativity, and economic opportunity.

Urbanism in the Age of Climate Change: Vision California

Editor’s note: This week and next, we’re presenting a 5-part series of excerpts from Peter Calthorpe’s book, “Urbanism in the Age of Climate Change.” This is installment number two. Thanks to Island Press, a few lucky Streetsblog readers will be selected to receive a free copy of the book. To enter the contest, fill out this form.

California’s effort to implement its new greenhouse gas reduction laws has provided a comprehensive look at urbanism and its potential in relation to a range of conservation and clean energy policies. The Vision California study, developed for the California High Speed Rail Authority and the California Strategic Growth Council, measured the results of several statewide land use futures coupled with conservation policies through the year 2050.5 The results make concrete the choices before us, the feedback loops, and the scale of both benefits and costs.

California is projected to grow by 7 million new households and 20 million people, to a population of nearly 60 million, by 2050.6 It is currently the eighth-largest economy in the world and therefore provides an important model of what is possible. The study compared a “Trend” future dominated by the state’s now typical low-density suburban growth and conservative conservation policies to a “Green Urban” alternative. This Green Urban alternative assumed that 35 percent of growth would be urban infill; 55 percent would be formed from a more compact, mixed-use, and walkable form of suburban expansion; and only 10 percent would be standard low-density development. In addition, the Green Urban alternative would push the auto fleet to an average 55 miles per gallon (MPG), its fuel would contain one third less carbon, and all new buildings would be 80 percent more efficient than today’s norm. It does not represent a green utopia, but it is heading in that direction. The results of this comparison highlight just how much is at stake and what the costs will be.

Remarkably, the quantity of land needed to accommodate the next two generations was reduced 67 percent by the Green Urban scenario, from more than 5,600 square miles in the Trend future to only 1,850 square miles. By comparison, the state’s current developed area is 5,300 square miles.7 This difference would save vast areas (up to 900 square miles) of farmland in the Central Valley along with key open space and habitat in the coastal regions of the state. The more compact future means smaller yards to irrigate and fewer parking lots to landscape, saving an average of 3.4 million acre-feet of water per year—enough to fill the San Francisco Bay annually or to irrigate 5 million acres of farmland.8 Less developed land also translates to fewer miles of infrastructure to build and maintain. The annual savings would be around $194 billion for the state, or $24,300 for each new household—not including the costs of ongoing maintenance. In addition, the Trend future would cost more in police and fire services as coverage areas increase.
