Traffic pollution: an invisible health risk for dozens of Denver schools

Interstate 70 is clearly visible from the playground outside Swansea Elementary School in Denver.

Just a few hundred feet from the front doors of Highline Academy Charter School’s southeast Denver campus is Interstate 25, where more than 200,000 vehicles rush by each day.

At Swansea Elementary School in north Denver, kids frolic near the busy Interstate 70 overpass that abuts the playground. Three miles west, at a charter school called STRIVE Prep – Sunnyside, the same highway looms just past a chain link fence next to the school.

The three schools are among 29 in Denver Public Schools — 10 of them charters — that sit near high-traffic roads and the invisible air pollution those routes generate daily. Experts say such pollution can stunt lung development, aggravate asthma and contribute to heart disease, but there’s little public awareness about the problem and mitigation efforts are sparse.

A new online mapping tool, part of a joint investigative project by two nonprofit news organizations, the Center for Public Integrity and Reveal, puts the issue in stark relief. Residents across Colorado and the nation can easily check which schools fall into red zones where traffic volume, and the accompanying air pollution, is worst, and orange zones where traffic volume is lower, but still potentially problematic for kids and staff who may spend long hours at their schools.

The Center for Public Integrity provided Chalkbeat with raw data for schools with Denver addresses. While most were DPS schools, a couple dozen were schools in neighboring districts, including Cherry Creek, Aurora, Westminster, Mapleton, Sheridan and Jefferson County.

Eleven DPS schools — educating more than 8,000 students — fell into the red zone, which means they sit within 500 feet of roads carrying more than 30,000 vehicles a day on average. Those include charters such as Highline and Strive Prep – Sunnyside, and traditional public schools such as Swansea and Steele elementaries and George Washington, Lincoln and East high schools.

Another 18 district schools, plus one in the Cherry Creek district and one in the Adams 12 district, fall into the orange zone, which includes schools that are within 500 feet of roads carrying more than 10,000 vehicles and more than 500 trucks daily. The 18 DPS schools include two additional STRIVE – Prep locations, two schools inside the downtown administration building and the district’s magnet school for students designated as highly gifted: Polaris at Ebert Elementary.

DPS officials say air pollution resulting from schools’ proximity to busy roadways hasn’t been discussed previously and that mitigation measures — such as high-grade air filters — aren’t in place at most affected schools.

“We haven’t had this conversation before,” said district spokeswoman Alex Renteria.

Sometimes schools end up near busy roadways because that’s where districts can buy cheap land. But population growth, development trends and major transportation projects can also dramatically change the fabric of a school neighborhood. Swansea Elementary, for example, was built in 1957, before I-70 sliced through north Denver in the 1960s.

The problem of traffic-related air pollution near schools is not exclusive to big cities like Denver. It can be found in suburban and rural areas around the state and the rest of the country. Many school districts across Colorado — from Montrose to Steamboat Springs to Greeley — have at least one school within 500 feet of high-traffic routes.

Charters harder hit

The investigation by the Center for Public Integrity and Reveal, which looked at trends nationwide, found that charter schools are more likely than traditional public schools to be located close to busy roads.
That’s true in Denver, where 22 percent of the district’s charter schools were located near a busy road during the 2014-15 school year, compared to 13 percent of other district schools. Nationwide, about 9 percent of schools are near busy roads, according to the analysis.

Officials at the most impacted Denver charter schools had little to say about the issue of traffic pollution.

Christine Ferris, executive director of Highline Academy, wrote in an email: “We can’t really do much about our location and although it would be obvious to anyone who visits us, having the information highlighted on Chalkbeat isn’t my favorite idea.”

She canceled a subsequent interview with Chalkbeat.

Chyrise Harris, senior director of communications and marketing for the STRIVE Prep charter group, said via email, “STRIVE Prep operates all of its schools in district facilities and works collaboratively with the district to ensure that all students, regardless of where they live, have access to a safe, high quality school near them.”

Jessica Johnson, general counsel and director of policy for the Colorado League of Charter Schools, said in growing cities like Denver there’s limited inventory when it comes to school sites. Charter schools may end up along high-traffic routes because that’s where the chartering district has vacant space and also because such roads provide needed proximity to bus or train stops.

Of the 10 Denver charter schools near busy roads, seven are in district-owned buildings. The three that aren’t are Highline, Cesar Chavez Academy and Justice High School.

While Johnson said being close to busy roads is a fact of life for urban charter schools, she noted the impact of traffic-related air pollution is an important health and wellness issue — one that hasn’t been on the charter community’s radar.

“This isn’t an issue that we’ve seen a lot of research into locally or a lot of conversation on,” she said.

Mitigation measures

Vehicle exhaust contains a variety of harmful components, including small particles, carbon monoxide and carcinogenic compounds. While outdoor areas like school playgrounds and sports fields pose an obvious risk, the air inside buildings can suffer, too, because particles, vapors and gases often seep inside.
High-grade air filters — those rated MERV 16 — can make a big difference. According to the Center for Public Integrity and Reveal investigation, MERV 16 filters installed in California schools caught about 90 percent of fine and ultrafine particles, which are key contributors to traffic-related health problems.

Denver schools use lower-grade filters, those rated either MERV 8 or MERV 10, according to district officials.

Air-conditioning can also help somewhat, allowing schools to keep some pollution at bay by shutting doors and windows in hot weather. Of the 29 DPS schools most impacted by roadway pollution, only four don’t have at least partial air-conditioning. Those are Valverde and Steele elementaries, Polaris at Ebert Elementary and STRIVE Prep – Sunnyside. While a handful of the 29 schools will get additional air-conditioning with funds from Denver’s recent voter-approved bond, those four are not on the list.

Swansea Elementary, the second most impacted Denver school after the southeast Highline Academy location, will be getting short-term and likely longer-term relief from traffic pollution.

Renteria said as part of a project underway now, the school is getting a new heating, ventilation and air-conditioning system that will include MERV 16 filters. It will also get new doors and windows.

Additionally, a planned highway widening project will convert the current overpass next to Swansea to a covered below-grade route. Research from the Environmental Protection Agency suggests vehicle emissions are lower near below-grade roads with steep walls. The same is true for routes with certain kinds of sound barriers or roadside vegetation.

The city will monitor air quality on Swansea’s grounds during and after construction.

Here is the list of schools classified as “red” or “orange:”

Children’s Health Insurance Program is on the brink. Here’s why that matters for education

The fate of the Children’s Health Insurance Program is in Congress’s hands — and children’s education, not just their health, may be at stake.

Congress passed a temporary extension of funding for of CHIP in December, through some states will run out of money shortly. The end of the program would come with obvious potential consequences, as CHIP, which covers approximately 9 million children, gives participants more access to health and dental care.

There may also be a less obvious result: Research has found that access to health insurance helps kids perform better on tests and stay in school longer.

A 2016 study, published in the peer-reviewed Journal of Human Resources, found that expanding Medicaid in the 1980s and 1990s increased students’ likelihood of completing high school and college.

“Our results indicate that the long-run benefits of public health insurance are substantial,” the researchers wrote.

Similarly, an earlier paper shows that broadening access to Medicaid or CHIP led to increases in student achievement.

“We find evidence that test scores in reading, but not math, increased for those children affected at birth by the increase in health insurance eligibility,” researchers Phillip Levine and Diane Whitmore Schanzenbach wrote.

In short, research suggests that when kids are healthier, they do better in school. That’s in line with common sense, as well as studies showing that children benefit academically when their families have access to direct anti-poverty programs like the earned income tax credit or cash benefits.

(Even if CHIP ends, affected children might still have access to subsidized insurance through the Affordable Care Act or other means. The Congressional Budget Office estimates that will be more costly in the long run.)

Congress appears likely to vote on a bill this week that includes a six-year CHIP extension, as as well as a temporary spending measure to avoid a federal government shutdown.

Business of education

Memphis leaders say diversifying school business contracts will help in the classroom, too

Winston Gipson confers with his wife and daughter, who help run Gipson Mechanical Contractors, a family-owned business in Memphis for 35 years.

Winston Gipson used to do up to $10 million of work annually for Memphis City Schools. The construction and mechanical contracts were so steady, he recalls, that his minority-owned family business employed up to 200 people at its peak in the early 2000s.

Looking back, Gipson says being able to build schools was key to breaking through in the private sector.

“When we got contracts in the private sector, it’s because we did the projects in the public sector,” said Gipson, who started Gipson Mechanical Contractors with his wife in 1983. “That allowed us to go to the private sector and say ‘Look what we’ve done.’”

But that work has become increasingly scarce over the years for him and many other minorities and women. The program designed to address contract disparities in Memphis City Schools was cut during its 2013 merger with Shelby County Schools.

A recent study found that a third of qualified local companies are owned by white women and people of color, but such businesses were awarded just 15 percent of the contracts for Shelby County Schools in the last five years.

It was even worse for black-owned construction companies, like Gipson’s, which make up more than a third of the local industry but were awarded less than 1 percent of contracts.

The disparity is being spotlighted as the city prepares to mark the 50th anniversary of the death of civil rights leader Martin Luther King Jr., who was assassinated in Memphis while trying to fight for the rights of minority workers in 1968.

On Jan. 25, Chalkbeat will co-host a panel discussion on how Shelby County Schools, as one of the city’s largest employers, can be an economic driver for women- and black-owned businesses. Called “Show Me The Money: The Education Edition,” the evening event will be held at Freedom Preparatory Academy’s new Whitehaven campus in conjunction with MLK50 Justice Through Journalism and High Ground News.

Community leaders say school-related business contracts are a matter of equity, but also an education strategy. Since poverty is a crucial factor in why many Memphis students fall behind in school, the lack of job opportunities for their parents must be part of the discussion, they say.

The district already is taking steps to improve its record on minority contracting, starting with setting new goals and resurrecting the city district’s hiring program.

Big district, big opportunity

Shelby County Schools is Tennessee’s largest district. With an annual budget of more than $1 billion, it awards $314 million in business contracts.   

An otherwise dismal 1994 study of local government contract spending highlighted Memphis City Schools’ program to increase participation of historically marginalized businesses as one of the county’s most diverse, though some areas were cited as needing improvement. The same study criticized the former county school system, which lacked such a program, for its dearth of contracts with Minority and Women Business Enterprises (MWBEs).

But when the two districts merged in 2013, the program in Memphis City Schools disappeared.

“We had to cut, cut, cut,” said school board member Teresa Jones. “We were trying to stay alive as a district. We did not focus as we should have.”

Jones, a former school board chairwoman, said it’s time to revisit the things that were working before the merger. “We have to get back,” she said, “to make sure there’s equity, opportunity, access, and an atmosphere that promotes business with Shelby County Schools.”

District and community leaders say the consolidated district has lost its ability to develop relationships with qualified minority-owned businesses.

“There was an infrastructure where African-Americans felt comfortable enough approaching the school system” for work, said Melvin Jones, CEO of Memphis Business Contracting Consortium, a black business advocacy group formed in 2015. “There was trust. During the merger, they dropped the infrastructure.”

Brenda Allen

Without the outreach, “we’re seeing the same vendors,” said Brenda Allen, hired last summer as procurement director for Shelby County Schools after working in Maryland’s Prince George County Public Schools, where she oversaw a diversity contracting program.

“We’re not marketing the district like we should,” she told school board members in November.  

Shelby County Schools is not alone in disproportionately hiring white and male-owned companies for public business. Just 3 percent of all revenue generated in Memphis goes to firms owned by non-white people, even though people of color make up 72 percent of the city’s population, according to a 2016 report by the Mid-South Minority Business Council Continuum.

Not coincidentally, district and community leaders say, Memphis has the highest rate of young adults who aren’t working or in college, and the highest poverty rate among the nation’s major metropolitan areas. About 60 percent of students in Shelby County Schools live in poverty and all but three of the district’s schools qualify for federal funding for schools serving high-poverty neighborhoods.

Jozelle Luster Booker, the CEO of the MMBC Continuum, developed an equity contracting program for the city utility company following the 1994 study that was so critical of the city. The program funneled half a billion dollars to minority-owned businesses — an example of how government policies can promote equitable contracting, and grow businesses too.

“When that happens, you could basically change the socioeconomic conditions of that community, which impacts learning,” Booker said. “They’re ready to learn when they come to school.”

Shelby County Schools plans to hire a consulting firm to help develop a procurement outreach program and set diversity goals for its contractors and subcontractors. The program will launch in July, and Allen plans to hire three people to oversee it.

The district also is part of a city-led group that provides a common certification process for businesses seeking contracts with city and county governments, the airport, the transit authority, and Memphis Light Gas & Water. The city’s office of business diversity and compliance also has a list of qualified minority businesses, offers free business development courses, and accepts referrals from other government entities to reduce redundancy.

“As you spend public dollars, you always want those dollars to be spent in your neighborhoods because that money comes back into your economy,” Allen said. “When people have jobs, you should see crime go down. You should see more people wanting to do business in the community if you have a good program.”

Leveling the playing field

In order for it to work, there has to be consistent reports, measures and, most of all,  accountability, according to Janice Banks, CEO of Small Planet Works, who helped the district with its disparity study.

Gipson agrees.

A wall of his second-floor Memphis office is lined with photos of some of his most significant projects during his 35 years of business, including a multimillion-dollar mechanical contract with AutoZone when the Memphis-based car part company moved its headquarters downtown in the early 2000s.

The work was made possible, he said, because of public sector jobs like constructing nine schools under Memphis City Schools. But that work evaporated after the merger. “It’s mostly been Caucasian companies that do the work (now),” he said. “It’d be one thing if you didn’t have anyone qualified to do it.”

Shelby County Schools will have to show commitment, he said, if it wants to level the playing field.

“You have the mechanism in place to make a difference,” he said. “Now do you make a difference with that mechanism or do you just walk around, beat your chest, and say we have a disparity study and let things run the way they’ve been running?”

“If you don’t make it happen, it will not happen,” he said.
