As a frontrunner in progressive metropolis options, the City of Cary was already dedicated to utilizing sensible expertise, information, and analytics to optimize metropolis features, drive financial development, and enhance the standard of life. Chief Data Officer, Nicole Raimundo, Good Metropolis Strategist, Terry Yates, and Stormwater Operations Supervisor, Billy Lee, noticed one other alternative: use expertise to foretell and handle flood occasions.

Envisioning a flood prediction answer

In October 2019, Cary’s leaders met with companions Microsoft and SAS, IoT division, to examine a brand new answer. The crew began by assessing the present scenario.

Throughout storm occasions, Cary had no visibility into the river ranges or how rapidly the water was rising. Historically, the city relied on residents to alert them of floods via cellphone calls, textual content messages, and different means. The city employees processed these requests manually dispatching public work personnel to erect boundaries and shut roads and first responders to emergencies.

The crew got here away with a imaginative and prescient for constructing a flood prediction system leveraging Azure IoT and SAS Analytics for IoT. Raimundo defined the necessity for the change.

“We felt strongly that the prevailing system wasn’t serving residents in flood-prone areas properly. We knew we wanted a scalable answer to get us from reactive to proactive and in the end predictive. The scalability of Azure IoT platform grew to become a vital part of our IoT structure. As well as, we required a sturdy set of analytical instruments that would ship perception from each real-time and historic information and SAS Analytics for IoT supplied that.” —Nicole Raimundo, Chief Data Officer, City of Cary

“There are millions of cities which are much like the City of Cary that need to deploy options to resolve city points reminiscent of flooding. Leveraging the Azure IoT platform and SAS Analytics for IoT these cities can transfer from being reactive to proactive and, in the end, predictive in a cheap, scalable method.” —Daniel Sumner, Worldwide Business Director, Authorities—Good Infrastructure at Microsoft

Defining challenge targets

Cary, Microsoft, and SAS agreed to a number of challenge targets outlined beneath.

  • Enhance the situational consciousness of city employees.
  • Automate stormwater personnel notifications and work order era.
  • Alert residents of flooding occasions.
  • Present information to downstream regional and state entities.
  • Analyze captured information and predict future flood occasions.

A key requirement for the City of Cary was that their new flood prediction system wanted to combine with current enterprise programs. These included utilizing the SAS Visual Analytics dashboard built-in with ArcGIS for real-time visualization, Salesforce for alerts, automated notifications and work orders, and information sharing for regional accomplice response programs.

“The Azure IoT platform has been a vital piece of our expertise ecosystem and accelerates our potential to scale.” —Terry Yates, Good Metropolis Strategist, City of Cary

Via a sequence of labor periods with the companions in February 2020, the crew created a challenge plan and system structure. Then the implementation work started.

Beneath are highlights of how the answer was constructed.

  • Microsoft Azure IoT Hub enabled a extremely safe and dependable communication to ingest stormwater ranges over an Firstnet LTE wi-fi connection. The crew used Azure IoT Hub to provision, authenticate, and handle the two-way communication to the sensors.
  • SAS Analytics for IoT mixed streaming sensors or gauges and climate information for real-time scoring, dashboarding, and historic reporting.
  • SAS Visual Analytics offered interactive dashboard, reviews, enterprise intelligence, and analytics. The dashboard is built-in with ESRI ArcGIS for added geographic evaluation and information visualization.
  • Microsoft Azure Logic Apps seamlessly built-in with Salesforce and different third-party purposes.
  • Microsoft Azure Synapse Analytics supplies information warehousing for Large Knowledge analytics.

Evaluating outcomes

The answer’s preliminary part has been working for a number of months with constructive outcomes.

  • City employees can now visualize flooding occasions in real-time.
  • Stormwater personnel obtain notifications and may generate work orders routinely.
  • A mechanism has been established to share information with regional companions.

“We’re nonetheless connecting among the dots, however we’re already seeing actual advantages within the automation of previously guide processes. Beforehand, we’d get a name from a citizen, which might trigger us to dispatch public works or emergency providers relying on the kind of flooding. Now the info triggers alerts that routinely notify stormwater personnel, who can react and tackle the flooded areas. It’s far more environment friendly and will in the end save lives.” —Nicole Raimundo, Chief Data Officer, City of Cary

Lee defined how thrilling it’s to have the ability to visualize water stream and utilizing the SAS Visual Analytics dashboard which is totally built-in with the ESRI ArcGIS.

“Now we are able to see a storm occasion in actual time. We will pull up the dashboard and see how a lot rain we’re getting. We will see the stream ranges rising and share this information with our regional companions. It’s wonderful to see the info in real-time.” —Billy Lee, Stormwater Operations Supervisor, City of Cary
