At a Glance


Using road collision heatmaps and other data to inform interventions, the City saw a 19% decrease in all injury collisions.


Monitored progress and changed course when needed to achieve traffic goals using Performance & Analytics strategies.


City’s staff telecommuting policy reduced employee commute time by 47,000 hours and saved the City between $300,000 – $400,000. It has also improved traffic conditions for all city residents and eliminated 424 metric tons of greenhouse gas emissions.


Budget and finance processes require data and alignment with the city’s 5-Year Strategic Plan, to ensure funds are efficiently and effectively allocated to address the most important priorities of the community.

The number of collisions involving bikes and e-bikes was already surging in Carlsbad when, in August 2022, two bikers were killed during a 10-day period. The City had issued an ordinance on e-bike safety a few months before, but the tragedies and an alarming 233% increase in collisions involving bike and e-bikes between 2019 and 2022 promoted greater action. City Manager Scott Chadwick declared a 6-month local emergency, which was ratified by the City Council at its next meeting. The emergency allowed the City flexibility to move quickly and focus resources on encouraging everyone to be safer on the road.

Some residents worried that the emergency declaration would lead to less access for bikes or more traffic. But Chadwick was able to reassure them. “We’re going to let the data guide us,” he said. And that is exactly what they did.

Immediately after declaring the emergency, the City began gathering and analyzing additional data on collisions. They created heatmaps to identify the most dangerous intersections, did a 5-year trend analysis, and set up tracking for the future. Armed with data and streamlined procurement processes as part of the emergency declaration, the City was painting key intersections and bike lanes with high-visibility green paint within two weeks. In fact, they moved so fast that they exhausted the supply of green paint in the region.

Within 30 days of the emergency declaration, the City had a full plan in place for improving street safety. The Safer Streets Together Plan seeks to change public behaviors and attitudes by focusing on education, engineering and enforcement. “It wasn’t just, ‘Here’s an emergency.’ The public saw real things happening in the first weeks and months and that’s how this has changed things so quickly,” Chief Innovation Officer David Graham said.

Six months after declaring an emergency, injury collisions across all transportation modes were down by 19% compared to the same time period in the previous year, and injury collisions related to bikes and e-bikes had decreased 13%. Graham points to qualitative measures of success as well – street safety yard signs and car window clings on display throughout the community, residents saying they are wearing helmets and slowing down, and the city’s partnerships with schools and bike organizations.

Because of the positive trends and evidence of behavior change, in March 2023 the City Council voted to extend the emergency declaration for a few more months. City staff hope that a year’s worth of data and analysis will help build a sustainable approach to traffic safety and that the early positive trends will become permanent.

The traffic safety emergency is not the first emergency that Carlsbad has tackled with data-driven decision making. It took a similar and equally successful approach during COVID. Hopefully the City won’t have cause for testing its emergency response again anytime soon, but having a well-honed system for collecting and analyzing data, and for innovating and tracking outcomes means that no matter what the future holds, Carlsbad will be well prepared to handle it.

“To see transformation in government you have to invest in areas that aren’t readily apparent like data and analytics, process improvement and operational excellence. When we work together with our community to discover shared insights around issues like traffic safety, we can create impactful change.”

David Graham, Chief Innovation Officer

It’s not easy to change the way people behave on the road. Often, you’re trying to change habits people have had for years or decades, for better or worse. By taking a balanced approach to traffic safety and digging into the data, we can see what’s working and what isn’t working, and learn how to be more effective as we move forward.

Proving That Smooth Data Practices Translate to Smooth Traffic

Project Type:
Community Engagement, Infrastructure, Public Safety, Transportation

At a Glance


10 transit intervention plans created for hotspot traffic areas.


Reduced annual traffic fatality rate to 6.2 per 100,000 residents—half the country’s overall rate.


Used strong Data Management practices to develop impactful traffic interventions with real-time data.


In recent decades, the leaders of Montevideo, Uruguay, have become familiar with a simple fact with far-reaching consequences: more people means more vehicles. As Uruguay’s commercial, political and cultural hub, Montevideo is no stranger to traffic. In 2015, its leaders set out to address the City’s massive traffic problem in a data-driven way. The City installed dozens of real-time sensors along major routes, created a new Center for Mobility Management to monitor and manage traffic data collection, and implemented a new mobility plan to cool off hotspots.

After building a data visualization platform that displays real-time traffic levels across Montevideo’s road network, and holding neighborhood meetings to understand residents’ traffic concerns, the City focused transit interventions on 10 particularly congested hot zones. Leaning heavily on sensor data analyses, they simulated the impact of different traffic engineering solutions—such as changing the timing and duration of traffic signals, or making a street one-way—and then settled on the most impactful options for each site. This access to high-quality, real-time data, combined with strong data governance practices, allowed the City to better understand the problem and then to develop and test tailored solutions for the hotspot zones.

“We don’t want to collect information just to verify the reality, we want to collect information to change the reality.”

Carolina Cosse, Mayoress

In addition to real quality-of-life improvements for Montevideo drivers, the City also realized environmental benefits, including reduced CO2 emissions, due to less idling, and better fuel economy. Moreover, the City’s commitment to improving traffic flow is helping to save lives. Montevideo’s annual traffic fatality rate is now 6.2 per 100,000 residents—half the country’s overall rate. City leaders believe that the installation of speed radars across the City, along with efforts to lower congestion in hotspots, has helped change driver behavior and prevent traffic-related deaths.

When you can measure a problem, you can manage it—and that’s exactly what Montevideo officials are doing, street by street.

“For us, What Works Cities Certification is a way to measure our performance. The goal isn’t to be happy with where we are now—although we’re proud of our progress—but rather to evolve and provide better services to residents.”

Charleston, South Carolina, USA

Creating a One-Stop-Shop to Track Progress on City Goals.

At a Glance


Charleston’s TIDEeye app helps the city and its residents monitor the effects of severe weather by providing real-time data on road closures and weather information.


Charleston has added almost 800 affordable housing units since 2016, and 500 more currently in the pipeline.


Data has shown that 86% of the affordable housing units in development are within .5 miles of public transit.


Known as a tourist destination with idyllic horse-drawn carriages, the City optimized equine waste management with GPS tracking. The system helped reduce cleanup time from 40 minutes to 20 minutes.


Using outcomes-based performance management practices to understand if programs are achieving their intended impact.

For cities with competing priorities and limited resources, making city-wide strategic goals built on data and evidence is an achievement in itself. But tracking progress, engaging residents and strengthening accountability is a tougher feat.

In 2022, the City of Charleston outlined six mayoral priorities and launched PriorityStat, an online dashboard and public meeting series to increase transparency and help the City and residents track progress on these six goals. While traditional city open data dashboards are organized around departments or services, PriorityStat takes a more innovative approach and is centered on City—and residents’—priorities.

For instance, FloodStat, one of the dashboards, is focused on protecting the City from sea level rise and flooding. In the 1950s, Charleston was impacted two  days per year on average by nuisance flooding. In the past five years, that average is now 61 days per year. Traditional dashboards would have relevant metrics, such as police complaints about flooded roads and properties, and city carbon emissions, in different dashboards since they’re in different departments. But addressing flooding and coastal challenges requires many departments to effectively work together. FloodStat helps break down silos by developing and regularly tracking metrics that require cross-agency collaboration. Additionally, it gives residents one place to see a more complete and clear picture of how the City is combatting its challenges.

Another one of the mayoral priorities is affordable housing. Home prices have jumped 78% since 2011 in Charleston—an unsurprising trend for a City with a 25% population increase since 2010 and more than 7 million visitors each year.

HousingStat allowed Charleston officials to develop a 10-year comprehensive plan to improve housing. To eliminate affordability gaps by 2030, the City learned that it needs more than 16,000 affordable units. HousingStat has also led to new programs, such as a Senior Homeowner Initiative, that has already helped 18 seniors become first-time homeowners. Regularly disaggregated data has helped the City allocate resources where they are needed most and develop more targeted strategies.

“We’ve been able to cut red tape on affordable housing initiatives. This is the largest, most ambitious affordable and workforce housing initiative in our city’s history.”

John Tecklenburg, Mayor

The City is clear that PriorityStat is still a work in progress. Two more dashboards are on the docket for 2024: one for mobility and transportation, and the other for neighborhood livability and resident quality of life. While these are being built, the City is actively seeking feedback and encouraging residents to watch public meetings on Charleston’s YouTube page.

PriorityStat is a performance management grand slam for the City. But more importantly it’s a win for residents. An unwieldy and unorganized performance management dashboard isn’t a platform that performs for residents. Charleston’s PriorityStat is different: by embedding accountability, transparency and collaboration into the fabric of the City’s strategic goals, residents know the City is making strides with them in mind.

Created Participa Mogi – an online platform for citizen participation. In its first year, the City received over 1,300 public contributions.


When employment data showed that 25% of Mogi workers were commuting outside of the City, Mogi added 7,000 new jobs in 2022 and increased revenue by 33% ($700 million BRL).


To combat hunger, Mogi das Cruzes created the Social Market Program, which connects farmers to over 1,200 families in vulnerable situations to receive free food.


Deployed innovative Qualitative Data Practices to better understand residents’ needs.

Mogi das Cruzes has found a winning combination. The City of more than 470,000 in São Paulo State is setting itself up for success by using data and community engagement as the foundation of its strategic plan.

Part of this plan includes giving the mic to Mogi’s youngest residents. Mogi das Cruzes wants to be a child-centered city. City officials are asking children for ideas for improving their neighborhoods so that the next generation engages with their government and community. In December 2022, Mogi announced its first “Our Neighborhood Detectives.” Between the ages of 9 and 12, these 24 children will participate in discussions and make suggestions about how to improve the quality of life and urban landscape for all children and adults living in Mogi.

“These boys and girls will represent the children in their neighborhoods and help us create a better city. Their input is an important complement to our data that will improve our decision-making and inspire civic engagement in young people.”

Caio Cunha, Mayor

The Neighborhood Detectives project is part of the Mogi Cidade da Criança (City of Children) program, which uses an innovative community engagement and design approach to inform the City’s investments in the wellbeing of its children. Another project within Mogi Cidade da Criança is monitoring air quality for its impact on children’s health. The air quality data is used to make decisions and create action plans, such as enhancing green spaces and encouraging active mobility to reduce emissions.

In addition to engaging its children in planning, the City seeks feedback from residents through regional meetings and neighborhood visits. By thoughtfully and rigorously soliciting resident input, the City is able to use this qualitative data to deepen community impact and better serve residents’ needs. For instance, the City asked for resident feedback about public transportation by conducting surveys in-person on the bus. Bus users were interviewed and the resulting data was used to optimize bus routes.

Mogi das Cruzes also created the Participia Mogi platform for residents to provide input on planning and budget priorities online. The City is opening its internal data up to residents as well, by hosting Open Data Days and making geospatial data available on the GeoMogi website.

“Staff perceive the need to use data in their day-to-day and Certification is helping with this culture shift. Once you have this cultural shift, you can’t go back.”

Caio Cunha, Mayor

Additionally, under the guidance of Mayor Cunha, the formula of data and resident input is being used to create a long-term, 40-year plan for the City. The ultimate success of the plan requires institutionalizing recent progress on collecting, managing and analyzing the City’s data. The Mayor’s hope is that residents will expect future administrations to continue the shared vision within a long-term plan: “We wanted this to be a plan for everyone, so we are building a sustainable program that represents the needs of the City as a whole, for today and for the next generation of Mogi residents.”

Fortaleza, Brazil

Data-Driven Approach Cuts Traffic Deaths by 57%.

Project Type:
Community Engagement, Infrastructure, Public Safety, Transportation

At a Glance


Reduced traffic fatalities by 57% over 10 years (2012-22)


1,086 lives saved


Eight consecutive years of fatality reductions


Mayor José Sarto signed a commitment to reduce fatalities by another 50% in the next 10 years


Monitored progress and changed course when needed to achieve traffic goals using Performance & Analytics strategies

At a recent public hearing on traffic accidents in Fortaleza, everyone participating shared that they knew someone who had lost their life or was critically injured in an accident. With 5 million daily trips and 29% of motorists on motorcycles, traffic fatalities have been an unfortunate part of life for Fortaleza’s 2.6 million residents.

In 2012, Fortaleza took action. Starting with historic traffic data, the City set goals and made evidence-based decisions about speed limits and traffic patterns. In 2021, it launched the Vida platform to consolidate traffic data from varying institutions and make it publicly accessible.

With these performance management and data-driven approaches, the City reduced traffic fatalities by 57% over 10 years. Additionally, the City established a road safety committee that meets every 15 days to review crash data and predictive analysis, using it to adjust strategies. The first city in Brazil to have a municipal road safety plan as law, Fortaleza has saved 1,086 lives and saved the City close to $42 million Brazilian Reals ($8.3 million USD).

“All of our actions, everything we do, is based on data and evidence.”

Elcio Batista, Vice Mayor

Still, Mayor Sarto is acutely aware that the City saw 158 traffic deaths in 2022, and he is committed to reducing fatalities by another 50% by 2031.

Fortaleza’s aim to realize Vision Zero—an international program working to eliminate all traffic fatalities and severe injuries—is just one of the data initiatives that has helped the City achieve What Works Cities Gold Certification. With its focus on data, the City has reduced school dropout rates, digitized its construction permitting process and launched an app to track sexual harassment on public transit. Fortaleza has also made progress on building a data culture: They developed a clear governance structure to coordinate data use, launched an Open Data Plan to guide data oversight, and concentrated over 200 datasets from 28 organizations in an Open Data Portal. By making so much City data publicly available, the City is promoting informed decision-making, transparency and robust resident engagement.

Vice Mayor Elcio Batista sees even more progress on the horizon. “Being Certified makes me proud and hopeful. Proud of what we have accomplished and hopeful for what is still to come.”

“By achieving Certification, it shows we are trying to do things the right way. It’s an honor for us, for the team, and it gives us a passport for the future.”

Launched a series of interactive datasets and maps for residents to track the city’s budget and capital improvement projects, promoting accountability and transparency.


Produced video tutorials and how-to guides to help residents understand and use the city’s new open data portals, encouraging public engagement and input.


Created a scoring index to measure the quality of every paved street in Topeka in order to prioritize street improvement projects and develop a cost-effective infrastructure improvement plan.

Topeka’s Not Afraid to Connect

If you had walked through the doors of Topeka City Hall earlier this year, a bright green and yellow banner would have greeted you with an engaging question: “How would you spend $96.5 million of the City of Topeka’s money?” The banner, jointly created by the city’s Administrative & Financial Services Department and Department of Neighborhood Relations, was posted in city administrative buildings downtown and invites people to visit the city’s performance portal to “Hold us accountable!” and “Track how we are measuring up.”

Topeka’s budget banner in the Cyrus K. Holliday Building.

It’s a high-visibility tactic to pull residents into the 2021 budget engagement process in Topeka, which sits along the Kansas River in the state’s northeast corner. The banner also signifies the capital city’s commitment to performance, transparency, and community engagement — all of which city officials see as crucial for building trust, meeting the needs of about 125,000 residents, and spending tax dollars efficiently.

A User-Friendly Foundation

Just a few years ago, Topeka’s government wasn’t nearly as open to its residents. The data revolution that spread across the country during the 2010’s changed that: city leaders committed to increasing access to data inside and outside of City Hall. And they started engaging the community to solve problems.

“The goal was and is to provide the public with greater access to city data and opportunities to work collaboratively on complex challenges facing our community. By increasing the city’s accountability, we were building trust with residents and changing the way the city operates.”

Deputy Director of Information Technology & Chief Software Officer Sherry Schoonover

The launch of Topeka’s open budget portal in 2015 marked a turning point. For the first time, residents could access datasets that showed, down to the line item, how the City aimed to spend their tax dollars. The City released its 2016 budget on the same portal, making the proposed budget accessible to residents for review and feedback. But the commitment to transparency didn’t stop there. In 2016, under the direction of Schoonover, the City launched the Topeka Capital Projects Dashboard. Its interactive map helps residents visualize the City’s capital improvement plan and get current information on capital projects across the city, including whether they’re on schedule and on budget.

Image of Topeka’s Capital Projects Dashboard and interactive map.

The same year, the City also set a strategic goal to increase data-driven decision making. Staff wanted to go way beyond offering snapshots of information through dashboards — so with the assistance of What Works Cities partners the Sunlight Foundation and the Center for Government Excellence at Johns Hopkins University (GovEx), the City launched a formal open data program, passed an open data policy and assembled a data governance team.

Proactive public engagement efforts also ramped up: the city manager launched a weekly report powered by the open data portal that offers updates from departments and divisions, and links to performance dashboards. To help residents navigate various portals, the City created video tutorials and how-to guides.

And for the first time in a decade, the City in 2018 conducted a Citizen Satisfaction Survey to align goals, policies, and spending with the priorities of Topeka residents. They voiced three top priorities: maintenance of city streets (the top concern), managing traffic congestion, and enforcing city codes and ordinances.

Data-Driven Streets

Well before survey results were in, City Hall staff knew that road conditions across Topeka were a weighty issue. A few years earlier, the city adopted a data-driven approach known as the Pavement Management Program (PMP) to prioritize improvements to this key infrastructure. The initiative would turn out to be crucial for winning public support for continued investments.

“The City of Topeka has been using data-driven decisions for years when developing our city’s goals and priorities. By using the Pavement Management Program, the City of Topeka has been able to build trust within our community in improving quality of life through infrastructure and transparency.”

Topeka Mayor Michelle De La Isla

PMP has three core components: the Pavement Condition Index (PCI), improvement strategies, and funding. The index scores the quality of every paved street in Topeka on a 0–100 range. A Fall 2016 assessment of all streets within the city’s jurisdiction showed:

  • 57 percent in poor condition
  • 18 percent in fair condition
  • 25 percent in good condition
  • An average system-wide PCI score of 55 (between fair and poor)

With this baseline data in hand, the City created a strategic plan for cost-effective street improvements built around measurable performance goals. In 2017, the Topeka Governing Body set a goal of pushing the average system-wide PCI score to at least 60 by 2029, and to be on course to reach an eventual PCI score of 70.

Image of Topeka’s Pavement Condition Index map.

Pushing the average score higher would cost millions in additional annual funding — a reality the public works team illustrated with detailed forecasts it presented to the City Council.

Table presented by the Public Works Department to the Topeka Governing Body during on Feb. 7, 2017, detailing the different funding levels, and corresponding backlogs, to achieve different PCI goals for street conditions.

If Topekans wanted streets to improve, they’d have to pay for it. In November 2018, they elected to do just that. Sixty-one percent of voters in the city approved a ballot measure that extended a half-cent sales tax for 10 years to fund street maintenance projects. If it had failed, the PMP would have lost more than half its budget — and the City wouldn’t have been able to maintain the 55 PCI score, let alone make progress on its goals.

The stakes were clear, so the City launched an interactive website informing residents how the money from the current half-cent sales tax was used for road repairs and what could be done if voters approved a 10-year extension. Videos showed road improvement strategies and before-and-after photos of repaired roads. Using predictive modeling, residents could peruse the data to see the impact of not renewing the sales tax.

All the upfront data-building work paid off — and the City Council brought into the PMP as well. To accelerate progress on street improvements, it allocated an additional $6 million over three years to ensure the city stays on track to achieve its PCI goal of 60.

Many Topeka residents likely haven’t heard of the Pavement Condition Index. But behind the scenes, it’s powering progress. If residents call the public works department asking why their neighbors’ street was repaved but theirs wasn’t, staff can now explain the decision, backed up by data.

Holistic Neighborhood Improvements

Streets are just one aspect of a neighborhood’s quality of life. Topeka has also taken a data-driven approach to understand the overall health of neighborhoods, and then outline a plan for strategic reinvestment. The City’s Team Up to Clean Up initiative, run by the Division of Community Engagement, provides hands-on help. Through this program, residents, city staff, local businesses, and community partners volunteer their time and services to breathe new life into areas in need.

It all starts with the data underpinning the City’s Neighborhood Health Map. Here’s how it works: every three years, the planning department updates the map to give each neighborhood an overall health rating based on poverty level, public safety, average residential property values, homeowner tenure, and the presence of boarded houses. Neighborhoods receive one of four overall ratings, akin to triage at a hospital. A “Healthy” rating is optimal; “outpatient,” is favorable; “at risk,” means negative conditions are emerging; and “intensive care,” means conditions are seriously distressed.

Image of Topeka’s 2017 Neighborhood Health Map. Courtesy of the City of Topeka.

The City prioritizes disadvantaged and socio-economically challenged neighborhoods rated as intensive care for Team Up to Clean Up, but selection also depends on the willingness of the Neighborhood Improvement Association (NIA) to work with the city. Once neighborhoods are selected, the Division of Community Engagement leads walk-and-talk sessions with community members to listen to their concerns, learn what supports are needed beyond home and street repairs, and link residents with social service organizations via a neighborhood resource fair.

In 2019, Topekans teamed up to clean up two neighborhoods, East End and Ward Meade. Volunteers painted home exteriors, trimmed trees, and replaced porches, and city staff repaired streets and sidewalks, among other activities. In the East End, Habitat for Humanity held workshops on home maintenance topics like siding repair and gutter care. The fire department, one of six city departments helping to improve the neighborhood, installed fire detectors and house numbers. By providing the NIA with tools and resources needed to sustain many of these efforts, the city aims to improve neighborhoods’ overall health ratings.

“This program illustrates that despite economic conditions, with community-wide support networks it is possible for disadvantaged neighborhoods to thrive and promote resources to improve the overall quality of life for their neighbors,” says Monique Glaudé, the city’s Director of Community Engagement.

A New Era Emerges

Years ago, city leaders heard criticism from stakeholders that the government was not transparent, that officials had something to hide. The City of Topeka still has its share of internal and external challenges — no city is perfect — but a lack of transparency is no longer one of them.

City leaders are committed to providing the public with timely and reliable information on decisions and performance, via City Manager Brent Trout’s weekly reports and other resources. Under Trout’s leadership, a Rapid Process Improvement initiative has streamlined city processes to eliminate redundancies and waste. That’s led to cost-savings for taxpayers and time-savings for city staff.

These efforts have not gone unnoticed by Topekans, says Mayor De La Isla.

“There’s an overall feeling that we are more approachable and responsive, and people have an understanding of what we are trying to accomplish for our community. We can go to sleep every night knowing what we are doing for our community and that we can show results.”

Data-Rich Sewage in Tempe, AZ.

Project Type:
Communications, Cross-Sector, Health & Wellness, High-Performing Government, Infrastructure

WWC - Gold Certification Badge for year 2021

At a Glance


Compiled data from the city’s sewage system monthly to track community drug use patterns and understand the depth of opioid use.


Using this data, monitored areas with high opioid use and deployed emergency response resources and abuse prevention interventions to hotspots accordingly.


Utilized similar wastewater testing data and tracking methods to monitor COVID-19 levels and identify outbreaks.

The Desert City’s Approach to Data

Like so many other cities in the country, Tempe, Arizona has been deeply affected by the opioid abuse crisis. The desert city of nearly 200,000 is part of Maricopa County, Arizona’s most populous area. This county also has the highest number of opioid-related deaths in the state.

As this public health emergency became more devastating in Tempe and around the country, Tempe’s leaders realized they needed to step up in two ways. First, they needed to be transparent about the severity of the problem facing the community. Second, they needed to create innovative solutions to help stem the opioid epidemic.

In 2018, the Strategic Management and Diversity Office, in partnership with ASU’s Biodesign Institute, submitted a proposal to the Tempe City Council Innovation Fund. The proposal focused on using wastewater to track the presence of opioid metabolites at the community level. City leaders supported the idea with innovation funds and began a partnership with ASU to tap this unlikely resource for data and to better inform decisions. Today, Tempe is on the cutting-edge of opioid abuse prevention work in the United States and has expanded this partnership to gather data on the presence of COVID-19 in the community.

“Cities may not want to call attention to opioid overdoses or abuse in their community,” said Wydale Holmes, a strategic management analyst in the city’s Strategic Management & Diversity Office.

“In Tempe, we’re courageously saying, ‘Yes, we have that, but we’re also doing something about it.’

It turns out that sewage offers an abundance of public health-related data — including a community’s drug consumption patterns. Tempe leverages its wastewater to identify areas of the city with elevated levels of opioid compounds — and then deploys emergency response resources and abuse prevention interventions to hotspots accordingly. All of this aligns to one of Tempe’s performance measures: ending opioid-related abuse and misuse by 2025, as measured by the percentage of 911 calls likely related to the drugs.

“Tempe is committed to data-informed community solutions. This first of its kind city model using wastewater-based epidemiology data informs strategic policy and operational decisions to advance community health.”

Director of the Strategic Management and Diversity Office Rosa Inchausti

It’s great to have data, but if you’re not doing anything with it or connecting it to resources and strategies for change, then it’s just information.”

Strategic Management Analyst Wydale Holmes

A New Diagnostic Matrix

Testing wastewater for real-time information about key markers of public health — everything from viruses to food contaminants to drug compounds — has been around for decades. But the approach is relatively uncommon in the United States. And no other city is trying to map the needs of residents around the opioid abuse epidemic in this way, said Dr. Rolf Halden, a professor at ASU’s Biodesign Center for Environmental Health Engineering.

“The United States is behind Europe. Every community that has done this work has not abandoned it, which is a testament to how well it works and how successful it is,” said Dr. Halden, who leads the wastewater data collection project in partnership with the City of Tempe.

Here’s how the wastewater analytics project helps the city identify opioid abuse hotspots and deploy resources strategically. Dr. Halden’s team takes raw sewage samples directly from five collection areas of the city for seven consecutive days each month. The scientists then test for four different types of opioids: fentanyl, heroin, oxycodone, and codeine.

After processing the samples, the ASU team hands off data to Tempe’s Enterprise GIS and Analytics team. The city can see where elevated levels of the four opioids are, and whether the opioids were metabolized or improperly disposed of. But the data contain no personally identifiable information — there is no way to tie data to specific addresses, neighborhoods or businesses.

Created by William Mancini for Fighting Opioid Misuse by Monitoring Community Health and provided courtesy of the City of Tempe.

All data are then published on the public Tempe Opioid Wastewater Collection Dashboard, created and maintained by Dr. Stephanie Deitrick, Tempe’s Enterprise GIS Manager. Through this dashboard and the Opioid Abuse Probable EMS Calls Dashboard, the information is analyzed by a multidisciplinary team, including Tempe’s Fire Medical and Rescue Department, to determine needed interventions. For example, if the data show a rise in opioid use among people under 18 in one area, the city might ramp up in-school outreach efforts. If one area suddenly becomes a major hotspot, the Tempe Fire Medical and Rescue Department can decide which emergency medical services and overdose prevention resources to move or increase to that area.

After implementing interventions, city officials can then track their potential effectiveness by monitoring changes in wastewater data alongside the EMS calls data. It’s a data feedback loop enabling the city to target its efforts — and, hopefully, prevent abuse and deaths.

“Dashboards allow people to quickly see overall trends within the data and to understand who is being impacted and where. Providing context is key when providing data to inform decision-making.”

Enterprise GIS Manager Dr. Stephanie Deitrick

Building a Data-Driven Culture

From its outset, the wastewater analytics project was directly tied to Tempe’s performance measure of ending opioid-related abuse and misuse. The Mayor, City Council, and City Manager set the expectation that reducing calls for opioid misuse or abuse was important to the executive leadership, and that both the goal and the performance measures supporting it needed to be shared internally with the City Council and administrative staff, community partners and externally to residents.

“Whatever we do, we always approach our employees and explain it to them and take the time to have the conversations about what we’re doing and why,” Tempe City Manager Andrew Ching said. “Every job has a purpose, and that job and that purpose exist within the framework of our strategic priorities and performance measures.”

City leaders also worked to communicate their efforts around the opioid abuse epidemic to the general public. The City of Tempe held an Opioid Town Hall in February 2019 to detail the wastewater project partnership and the types of support that Tempe provides to its residents struggling with opioids, their families and caregivers.

Anyone can visit the wastewater data dashboard and the Opioid Abuse Probable EMS Call Dashboard, designed and conceptualized by Dr. Deitrick and her team. The latter dashboard, which launched in 2018, gives Tempe Fire Medical and Rescue Department and the public a window into opioid abuse in the community. It details when calls related to abuse occurred, along with patients’ ages and genders, and the number of times Narcan/Naloxone overdose reversal medication was used during opioid-abuse related emergency calls.

Together, both dashboards inform Tempe officials’ efforts to end opioid misuse and abuse in the city, and help first responders and public health agencies on the ground see the impact of the targeted outreach and other interventions. It’s too early to tell how quickly the city will advance toward its goal — it was officially set in December 2019, when the baseline percentage of opioid-related EMS calls was 3.74 — but the right approach to data is in place to drive progress.

As the COVID-19 pandemic took hold around the world and in Tempe, city leaders have once again partnered with ASU wastewater researchers and are using this data in the same manner as the opioid data. The city is following the data to find areas of greatest need and is directing resources to help.

2023 Gold Certification


Several years ago the City of Syracuse teamed up with the Syracuse Metropolitan Transportation Council (SMTC) to create a data-driven prioritization for road reconstruction. This year, the City and SMTC introduced an equity component to the priority scoring process to ensure that the City does not overlook roads in historically underserved neighborhoods. Inspired by equity score systems in other cities, the City created a metric to measure the amount of historically underserved residents in an area. The new model considers the equity score as well as road conditions when recommending reconstruction projects for the year. In this way, the City avoided completely reinventing the reconstruction priority process while introducing equity as an additional factor.

The Snowiest City

Syracuse, New York is seriously snowy. Averaging more than 120 inches of snowfall each year, it’s officially the country’s snowiest city. Throughout each long winter, staff in the Department of Public Works (DPW) work to keep roads and sidewalks clear and safe so residents can keep moving. Until a few years ago, Syracuse’s snow removal services were challenged, resources were limited, and many residents weren’t happy.

“I used to want to avoid Facebook every time we had a storm,” says Corey Dunham, the City’s chief operating officer. “There were just too many friends and family complaining about the snow on their streets!”

When Mayor Ben Walsh took office in 2018, he was determined to take a new data-driven approach to tackle persistent problems facing Syracuse residents. Whatever the problem in Syracuse today, a first step toward designing a solution is to dig into data. “You can’t fix what you don’t fully understand,” Mayor Walsh said in his 2019 State of the City address. Data helps the City understand the causes of problems and address them, he added.

With clear support from the Mayor’s Office, city staff have worked in recent years to build foundational data practices including general management, performance & analytics, and open data to improve the delivery of city services like snow removal. The aim is to deliver efficient, effective, and equitable services — a goal that has become core to Walsh’s administration.

“We’re not data-driven for the sake of being data-driven. Data empowers us to know if we’re being effective or not, and then pivot when we need to change.”

Syracuse Mayor Ben Walsh

Deputy Mayor Sharon Owens admits she was once a “data nonbeliever.” Now she has the passion of a convert. “Being able to use data to hone in on quality-of-life issues is crucial,” Owens says. “We spend too much time sending out a wide net when we should be honing in. Residents are impacted by our ability to take data and use it to solve the problems they care about.”

Plowing Through Data

The Parks Department and DPW’s effort to overhaul how they prioritize clearing snow from roads and sidewalks shows how data can translate into better and more transparent city services.

During snow events, the DPW snow plows move into action. The department follows a system of prioritizing city streets for snow removal: the first priority is always emergency routes, followed by hills around the city and roads with significantly higher levels of traffic. Flatter city streets generally found in residential neighborhoods come next.

The City compiled data from GPS units in each snowplow to create and publish an interactive map on the City website, enabling residents and property owners to track the path of snowplows during storms to determine if a street was already plowed. The map includes timestamps of a plow’s most recent pass of a street. The data also equipped the DPW staff to more quickly and accurately identify any streets a snowplow may have missed on its run.

To improve sidewalk snow clearance, the City took a similar approach. Working with the Syracuse Metropolitan Transportation Council, a team of DPW staff members and transportation planners first mapped foot traffic, building a dataset detailing which sidewalks are used most frequently and which are adjacent to the most dangerous streets. Again, data analysis showed the obvious snow removal strategy.

“We determined the most dangerous streets for pedestrians and cleared sidewalks in those areas first. Using data, we were able to make and defend decisions about why we chose to clear certain streets and sidewalks over others.”

The Department of Parks, Recreation and Youth Programs also dug into data to improve its approach to snow removal. The first step was mapping all the sidewalks and walkways in Syracuse’s 164 parks it is responsible for — 13 miles total, the department learned. Previously it would take three days after a major snow event to clear all sidewalks and walkways. After creating a color-coded map making priority routes clear — and buying two Bobcat L28 machines enabling a sidewalk to be cleared in just one pass — the department now clears them in just six hours.

Syracuse officials have also used more data-driven budgeting practices to save money on road de-icing materials. Previously, each department across the city was managing its own financials and budgeting from budget-to-budget, instead of actuals-to-budget. By centralizing the budget planning process and providing actuals to departments, Syracuse was able to make better spending decisions. This approach allowed DPW to analyze data for how much salt it purchased each year for de-icing and how much salt it actually used. The ultimate outcome: officials were able to better predict how much salt they needed to buy. Last year, the data-driven effort helped the city save an estimated $800,000 on salt purchases.

More Results to Come

Syracuse’s efforts to strengthen its data culture and practices have yielded benefits beyond snow removal. The City has also used data-driven problem-solving skills to address more complex challenges, such as poverty, inequities highlighted by the COVID-19 pandemic, and neighborhood revitalization efforts.

Looking ahead, exciting things are in the works — all fueled by the data capacity Syracuse has built. Later this month, the City plans on unveiling a brand-new resident information system revamping its city service request system into a more comprehensive and user-friendly portal.

And by the end of the year, Syracuse will build the first 25 of 200 one- and two-family housing units through the new Resurgent Neighborhood Initiative (RNI). The program supports city neighborhood planning and revitalization at the block level. Affordable housing construction locations were chosen by analyzing quantitative data detailing the locations of vacant and unused properties, and gathering qualitative data through 800 resident interviews conducted over eight months. This stakeholder engagement helps ensure equity, so the City can better deliver on the promise of affordable housing.

“Whether the challenge is housing, a pandemic, or snow removal, being a data-driven city means efficiently, effectively, and equitably delivering services that taxpayers pay for,” Mayor Walsh says. “This is the nuts and bolts of local government.”

Seattle: Transforming a City in Fast-Moving Transition.

At a Glance


Initiated a data-driven approach to homelessness intervention that reoriented providers’ thinking — and their service delivery models — around the goal of ensuring any experience of homelessness in Seattle is rare, brief, and one-time.


Used a results-based contracting approach to monitor contract progress and encouraged contract managers and providers to meet regularly to review performance data.


Developed a dashboard focused on homelessness-related data from twelve departments to have better situational awareness of the homelessness crisis, in addition to how human services programs are performing.

Seattle is More than a Cup of Coffee

Fast-paced economic development is bringing plenty of high-tech jobs to Seattle and leading to spikes in household incomes, but progress isn’t being felt by everyone. It’s also contributing to a severe shortage of affordable housing and a homelessness crisis that led the City to declare a state of emergency in November 2015. This wasn’t for a lack of funding directed toward the city’s most vulnerable residents; Seattle’s budget for homeless services grew from $29 million in 2005 to $50 million in 2016 while homelessness continued to rise. Struggling to keep up, the City had to take a hard look at how it was tackling the crisis.

In response, the City launched its Pathways Home plan to shift its focus away from emergency, short-term interventions toward longer-term solutions, using data-driven decision-making to guide the way. As the City says, “Every dollar spent on emergency beds is a dollar not spent on strategies that allow people to exit homelessness.” A critical aspect of the plan was to rethink relationships with outside providers that contract with the City’s Human Services Department (HSD) to provide homelessness services, beginning with a pilot of $8.5 million worth of contracts. The pilot was carried out as part of Seattle’s engagement with What Works Cities partner the Government Performance Lab at the Harvard Kennedy School.

George, Maria, and their young son are among families that nonprofits contracted with the City have helped to move into permanent housing.

Through the pilot, providers were no longer tracking indicators like how many beds were filled or meals were distributed, but rather metrics such as how many people moved into permanent housing or became homeless again after being served, and how long they experienced homelessness. The approach reoriented providers’ thinking — and their service delivery models — around the goal of ensuring any experience of homelessness in Seattle is rare, brief, and one time. By using a results-based contracting approach, that’s what the City began holding providers accountable for too; contract managers and providers began meeting regularly to review performance data, enabling the City to troubleshoot problems in real time and spread the most effective practices.

“It’s not just about more money, although more resources is important. It’s also about thinking and how we do our work differently. How do we use data in a way that is not just compliance-driven, but helps us figure out what is working for people we’re trying to support out of crisis?”

Human Services Department Director Catherine Lester

Seattle has just expanded the pilot to $34 million in contracts awarded to bidders following the issuance of the City’s first competitive RFP for homelessness services in ten years. By keeping providers on target with performance benchmarks, the City aimed to double the number of people being moved into permanent housing by the end of 2018. Seattle is also expanding the performance-based model even further — across the entirety of HSD, which invests $105 million in contracts annually. Simultaneously, the City is developing a dashboard that will bring together homelessness-related data from twelve departments to have better situational awareness of the homelessness crisis, in addition to how human services programs are performing. Soon, real-time data will be available to staff, enabling a more coordinated, citywide approach to tackling the problem, tracking vendor performance, and more.

These efforts are part of a larger culture of data use throughout City Hall. Seattle was one of the first cities in the country to pursue open data and has a robust approach to engaging residents that goes beyond simply publishing data sets on its open data portal. The City is also advancing skills it developed with What Works Cities partner the Center for Government Excellence at Johns Hopkins University by rolling out performance management citywide. To help facilitate that process, the City’s Office of Performance is conducting twelve-week engagements with departments on a rolling basis to train staff. “Getting people the right resources — that’s what’s critical to getting the job done,” says former Organizational Performance Director Tyler Running Deer, who also worked extensively to help departments link their performance and budgeting goals. Seattle is also sharing progress toward citywide goals via its performance portal, one of several public-facing ways residents are kept informed.

After data showed that use of a former bikeshare program wasn’t offsetting its cost or meeting users’ needs, the City piloted a dockless model.

By tracking data and seeing what works, Seattle is learning important lessons about when and how to allocate funding, manage programs, or sometimes, when to shut them down. In one recent example, the City rolled out a bike share program, but data showed use wasn’t offsetting the cost and the service wasn’t meeting users’ needs. Bike docks were taking up valuable parking space, much to the dismay of local business owners. A highly-used station was located on a hilltop, so users weren’t returning the bikes, leaving the task to a truck that drove large numbers of bikes back to the dock at the end of each day. Now the City is piloting a dockless model with three different companies that are funding the program through their own revenue, and had to provide a data-collection plan before receiving permitting. Users can take the new bikes on the routes they truly travel and park them in more convenient locations. Without the temptation to concentrate docks in the highest-income areas, the hope is that bike access will also become more equitable. So far, the results seem promising, but for this city, there’s more than time that will tell — there’s also data.

2023 Gold Certification Highlight:


For several years the City of Scottsdale has been tracking and monitoring short-term rental properties and complaints about them. In 2022, the Arizona Legislature passed a law allowing cities to license short-term rentals and regulate nuisance properties. The City quickly sprang into action, adopting rules requiring short-term rentals to be licensed and creating Good Neighbor Guides to educate short-term rental property owners and their neighbors about the requirements. The CIty also created a Short-Term Rental Map Tool that allows residents to view the license status and understand the impact of short-term rentals in their neighborhoods. The Map Tool draws on the City’s Data Service Standard – one of the first cities in the United States to publish one – that guides the City in developing reliable and informative data services and products for its residents and businesses.

Honoring Scottsdale’s Memory

The skies were clear blue at noon as a crowd cheered the world’s oldest official Pony Express to the end of its 200-mile journey, outside the Museum of the West, in Old Town Scottsdale. This annual delivery of 20,000 pieces of first-class mail is among the special events and other attractions that bring about 9 million visitors and around $41 million in tax revenue to this Southwestern city each year. Old Town, the City’s downtown, still grows olive trees from its first days of settlement in the late 1800s, at the same time that it has become the spring home of the San Francisco Giants and begun to emerge as a center for high-tech businesses. It’s just one manifestation of how Scottsdale, the “West’s Most Western Town,” is a city that remembers its past while steadfastly preparing for the future.

Adopting a Business Mindset in City Hall

Scottsdale stands out for adopting a business mindset to run a well-managed government, embracing transparency so that residents receive the information they deserve, and embedding data in decision-making to ensure the best outcomes. And the efforts are paying off — in conserving water, serving vulnerable residents, minimizing traffic jams, and beyond.

Scottsdale joined What Works Cities in June 2016 and, soon after, codified an open data policy and launched an open data portal. Scottsdale has also deepened its citywide performance management. City Manager Jim Thompson says, “When we look at data and analytics, even though we assumed something was best, when we overlay old data with new or more specific data, we may find a new way to do things.” To continuously evaluate progress is to continuously improve.

The City is publicly reporting on that progress through a public-facing performance management portal, and provides performance data to collective benchmarking databases, an effort that allows cities to help each other set more informed targets and put their own progress into perspective by comparing themselves to other similar municipalities regionally and nationally. Scottsdale has gone on to earn a 2018 Certificate of Excellence in performance management, the highest distinction, from the International City/County Management Association.

If it’s a flaw in a process that’s causing shortcomings in performance, Scottsdale has a solution for that, too: a cross-departmental team that helps colleagues from across City Hall implement process improvements. A recent project involved modernizing the website for reserving facilities like picnic areas or volleyball courts from the Parks & Recreation Department. What was once a landing page with instructions to call a landline transformed into a full-service resource for determining availability and making a booking. Use of the website increased 200 percent in the first month following the redesign. Most importantly, residents are happier, and the ability to provide better customer service is boosting morale among department employees.

Making Every Drop Count

The Scottsdale Water Department Director Brian Biesemeyer was acting City Manager when Scottsdale’s open data work got underway, so it’s no surprise that he’s pointing his team to the numbers to make sure “every drop counts,” as he aptly puts it. As a desert city, Scottsdale understands the value of water to residents and the economy.

Scottsdale’s Central Arizona Project water treatment plant on its Water Campus.

Each year, by October 1, the department must submit its water order for the following year — meaning calculations for projected water needs are already underway 14 months out. In 2018, by using predictive analytics, there was a difference of fewer than 100 million gallons (or 0.4%) between planned and actual water use. An inaccurate prediction could have required tapping into underground aquifers — a crucial reserve in this arid city — or paying for water it didn’t use. An accurate water order not only saved money; it allowed the department to continue to recharge local aquifers. In doing so, the City continued a 20-plus-year streak of pumping less groundwater out of its aquifers than it puts back in. Scottsdale was the first city in Arizona to achieve this feat — known as safe yield — and has received the Sustainable Water Utility Management Award, from the Association of Metropolitan Water Agencies, the highest industry recognition for municipal water providers. Accurate data analysis and transparency help drive better planning practices that benefit Scottsdale residents now and over the long term.

Data analysis has also saved the department nearly half a million dollars each year by tracing the need for costly meter replacements in one part of the City to a pH imbalance, now corrected, originating from the water plant serving the affected area.

Gathering BITS of Insight

Scottsdale regularly communicates with residents on everything from issuing water bills to recruiting new employees. When Scottsdale joined What Works Cities, it expressed an interest in identifying which messages resonate best with local residents. Scottsdale city staff teamed up with the Behavioral Insights Team (BIT) to determine the answer by using randomized control trials to test the effectiveness of messaging and keep tweaking them accordingly. Pretty soon, they identified messages on utility bills that led to more customers donating $1 per month to local nonprofits, or signing up for paperless billing, a more eco-friendly, cost-effective option.

After ending technical assistance with BIT, the City created a team of internal consultants — the Behavioral Insights Team Scottsdale, or BITS — to carry the work forward by helping staff in departments across City Hall apply behavioral science to their projects. The department that’s engaged most with BITS has been Human Services; they’ve identified effective messaging to recruit more volunteers for programs focused on assisting vulnerable seniors, including Beat the Heat and Adopt-a-Senior.

Most recently, they’ve focused on Adopt-a-Family, a program that recruits volunteers to provide food and gifts for income-eligible families during the holiday season. Human Services Specialist Sue Oh recalls a 2018 volunteer who received a family’s wish list, which included a request for a boy’s polo, and wanted to find out what style the child wanted.

When Oh reached out on behalf of the volunteer, she learned that the child’s mother had passed away; his grandmother was now caring for him and his siblings. Oh related this to the volunteer, who began to cry and shared that her husband had recently passed away. She said, “I know this is what I’m supposed to do,” Oh recalls, and voiced her plans to volunteer again this holiday season.

By integrating testing into communications, Scottsdale is more effectively and efficiently engaging with its residents.

The Road Ahead

Scottsdale’s Traffic Management Center.

Sometimes the effects of using data are quietly unfolding behind the scenes of what most residents see on a daily basis. Take the City’s Traffic Management Center, where analyzing the effects of altering traffic signals after prior accidents has informed the development of data-based, location-specific plans for minimizing traffic jams after future accidents. Now staff are turning those human-gathered insights into algorithms that will eventually allow machine learning to respond with greater precision.

There’s a lesson here: Getting from point A to point B in the best way possible is a great goal for the road — and a useful metaphor for driving progress effectively — but it always involves planning ahead. As Assistant City Manager Brent Stockwell drives back to City Hall after our visit to the Traffic Management Center, he paraphrases how a former council member once put it: “See those trees planted there? They’re there because someone in the past was thinking about the future.”
