Manville on How Toll Roads Change Driver Behavior

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville spoke to Community Impact Newspaper about ways to reduce traffic congestion on roads and freeways. The Central Texas Regional Mobility Authority has broken ground on its $612 million expansion of US 183 North in Austin, Texas. The project will add four express toll lanes and two general-purpose lanes, making it 18 lanes wide in some areas. While Manville said he sees advantages in express lanes, he is skeptical the project will actually reduce congestion because adding non-toll lanes will induce demand and cause more people to use them. Manville explained that he prefers toll roads because they force drivers to consider the time involved and how they make trips. “If you just changed the behavior of a small number of people who might get on that road, the road works a lot better, carries more people, there’s less congestion, and you actually have a high-quality service,” Manville said.

Manville Sees Pandemic Shift in Parking Paradigm

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville spoke to Commercial Observer about how the pandemic opened up new possibilities to utilize streets and parking spaces. Many restaurants were able to save their businesses by expanding outdoor seating into parking lots and street parking spaces; other parking spaces have been converted to electric vehicle charging stations and even ghost kitchens. “The pandemic gave everyone this very vivid illustration of how much space, even in very vibrant parts of their area, is devoted to surface parking,” Manville said. “It helped them understand, more than any other sort of medium could, just how much of this scarce resource of urban land is devoted to holding empty cars.” These pandemic-triggered changes have accelerated a shift toward reevaluating the parking paradigm, including a Los Angeles city ordinance that does not require builders to add new parking and efforts to transform some downtown parking structures into affordable housing units.

Urban Planning Alumna Leads National Endowment for the Arts

/0 Comments/in /by

Urban Planning alumna Maria Rosario Jackson PhD ’96 has been confirmed as chair of the National Endowment for the Arts, becoming the first African American and Mexican American woman to lead the federal agency. “The arts are critical to our well-being, to robust economies and to healthy communities where all people can thrive,” said Jackson, a professor at Arizona State University who has served on the National Council on the Arts since 2013. For more than 25 years, Jackson’s work has focused on understanding and elevating arts, culture and design as critical elements of strong communities. She has served as an advisor on philanthropic programs and investments at national, regional and local foundations, including the Los Angeles County Cultural Equity and Inclusion Initiative and the Smithsonian Center for Folklife and Cultural Heritage. She serves on the board of directors of the Performing Arts Center of Los Angeles County, among other organizations, and her work appears in a wide range of professional and academic publications. She also taught a UCLA course on arts, culture and community revitalization. Jackson grew up in South Los Angeles and credits her parents with instilling a love of the arts in her family. “Our art, culture and creativity are some of our country’s most valuable resources,” she said. “They are evidence of our humanity, our ability to learn from our examined experience, and our ability to imagine and innovate.” President Joe Biden nominated Jackson to the NEA post in October, during National Arts and Humanities Month; her appointment was confirmed by the U.S. Senate on Dec. 18.

Manville on Showdown Over California Housing Laws

/0 Comments/in /by

An NBC News report on a looming showdown over new California laws aimed at building more housing included insights from Associate Professor of Urban Planning Michael Manville. The laws going into effect on Jan. 1 include Senate Bill 9, which will allow property owners to construct more than one unit on lots previously reserved for single-family homes. Opponents say the laws will strip cities and counties of control over zoning and will not ensure that new units will be affordable. A proposed constitutional amendment that would undo several of the laws may appear on the November 2022 ballot. The debate illustrates how difficult it is to address the state’s affordable housing crisis. “It took a long time for us to get into this hole, and it’s going to take a long time to get out,” Manville said. “It’s going to take some time to see so much construction that rents are going to fall.”

Wasserman Cautions Against Overinvesting in Rail

/0 Comments/in /by

Jacob Wasserman, research project manager at the UCLA Institute of Transportation Studies, spoke to the Los Angeles Business Journal about the explosion of rail construction projects in Los Angeles. Four major rail projects are currently under construction in L.A. County, with several more projects in the pipeline. “For the modern era, this is a huge investment in rail transportation on the scale rarely seen in recent memory,” Wasserman said. However, rail transit ridership has been steadily declining in L.A. County, a trend that was exacerbated by the COVID-19 pandemic. As a result, Wasserman cautioned against overly investing in rail. “Remember, the vast majority of people taking transit in L.A. County take the bus, so the rail system has drawn a disproportionate amount of funding and resources,” he said. “Rail should be reserved for those instances where the congestion and density are high enough that there’s a demonstrable time savings over other modes of travel.”

Single-Family Zoning Causes Harm, Manville Says

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville joined Detroit Today to discuss the effect of single-family zoning laws on wealth, access and opportunity. In most cities, the majority of residential land is zoned for single-family housing. By preventing non-single-family homes from being constructed in certain areas, Manville noted that single-family zoning hinders access to wealth for new, younger homebuyers, reinforces segregation and exacerbates issues of housing affordability. “My objection has nothing to do with single-family homes themselves,” Manville explained. “It’s the idea that you can have a law saying that nothing else can be built.” In metropolitan areas undergoing growth, single-family zoning drives up the minimum purchase price to be a part of the community, and this barrier has adverse consequences that fall disproportionately on low-income people and people of color. “Regardless of motivation, keeping these barriers in place causes harm, and we would do some good to remove them,” Manville concluded.

Pierce on Municipal Approaches to Heat

/0 Comments/in /by

Gregory Pierce, co-director of the UCLA Luskin Center for Innovation, co-authored an article in Planetizen discussing different cities’ approaches to addressing extreme heat. “People of color and those with lower incomes are disproportionately exposed to heat, and the largest health risks fall on seniors, young children and those with chronic conditions,” Pierce wrote. Climate change has led to an increase in heat-related deaths and hospitalizations. In a recent paper published in the Journal of Planning Education and Research, Pierce and his co-authors analyzed surveys by California’s Office of Planning and Research to determine what factors influence whether municipalities actively plan for extreme heat and what kinds of heat-related planning and policy innovations they have adopted. The authors recommended making social equity a top priority in heat adaptation planning. They called for engaging with local communities and directing investments where they are needed most to eliminate thermal inequity.

Goh Rethinks Emergency Preparedness

In an interview with Curbed, Assistant Professor of Urban Planning Kian Goh offered her input on developing climate adaptation plans to address increasingly frequent flooding in New York City. Nine years ago, Superstorm Sandy wreaked havoc in the city, killing 44 people, destroying 70,000 homes and causing $19 billion in damage. New York City has had three major cloudburst-flooding events over the past two months, reigniting conversations about how to best prepare for inevitable future storms and flooding events. “It’s not a matter of resources, it’s a matter of planning,” Goh said. She highlighted the need to identify and address infrastructural inadequacies and rethink emergency preparedness. For example, the Dutch city Rotterdam has built “water squares” that serve as recreational spaces between buildings but can also be a place for stormwater during flooding events. “It’s about convincing engineers and maintenance crews and city budget officials that there’s a different way to do things,” Goh said.

Koslov on Social Causes of Climate Vulnerability

/0 Comments/in /by

Assistant Professor of Urban Planning Liz Koslov was featured in The City discussing a proposed voluntary buyout program for flood-prone houses in New York City. After Hurricane Sandy, many homeowners sold their properties back to the state through the Oakwood Beach buyout program. That successful effort was community-led and the housing stock was mostly single-family homes, Koslov said. Going forward, “a lot of the homes in the places that we now see are most at risk are also the most affordable,” she noted. Koslov pointed to social causes of climate vulnerability, including redlining and disinvestment, that cause people to live in those risky places in the first place. “If you’re just trying to un-build places that seem to be the most at risk, but you’re not addressing the underlying causes of that risk, which go far beyond climate change, it’s never going to satisfactorily or equitably reduce the risk that exists,” she said.

Manville Explains Equity of Congestion Pricing

/0 Comments/in /by

Associate Professor of Urban Planning Michael Manville spoke to the Washington Post to help debunk myths about highways and traffic. While some cities have widened their highways in an attempt to decrease traffic, “the iron law of congestion” explains the phenomenon in which widening highways results in a proportional increase in cars on the road. Some economists and urban planning experts, including Manville, have proposed congestion pricing as a solution to traffic congestion by making drivers pay for the space they take up on the highway. Some opponents of congestion pricing have argued that the policy would hurt the poor, but Manville responded, “Free roads are not a good way to help poor people.” Manville explained that affluent people drive more regardless of whether or not congestion pricing exists, so the best way to help low-income residents is actually by improving infrastructure and public transit, which can be funded through congestion pricing revenue.
