CASE STUDY
Flooding in the lakefront communities of Seminole County is asignificant hazard for people and property. With its 10−yearstormwater master plan, the City of Casselberry wanted toknow how its stormwater assets were performing, starting withGee Creek.
Gee Creek is the primary discharge point for Lake Kathryn,which covers 74 acres. Several upstream lakes also feed intoLake Kathryn. Previously, the City mitigated floods by manuallyoperating a gate in the weir at Gee Creek and determined riskby manually reading staff gauges.
The City implemented Opti continuous monitoring and predictiveanalytics to optimize surveillance of Lake Kathryn elevation inorder to protect the surrounding neighborhood from flooding.
Weather forecasts and rainfall are used to provide predictedinflow to Lake Kathryn while real-time monitored water leveldetermines discharge based on a range of possible weirconfigurations at the outlet structure. Geosyntec Consultantsprovided the design and operational protocols for this project.
Solar-powered Opti monitoring paneland water level sensor provide real-timedata at the Gee Creek outlet structure.

Casselberry uses Opti’s web-baseddashboard and alerts to create a predictiveflood-stage monitoring program. This helpsthe City determine when to lower or raise theweir at Lake Kathryn to reduce the risk ofneighborhood flooding. Benefits includeshortening emergency response time tooptimizing O&M. Opti key performanceindicators include:
By continuously monitoring stormwaterinfrastructure, Opti creates relationshipsbetween asset performance indicators likedrawdown time, and physical conditionssuch as clogs or leaks.
By comparing current and forecastconditions, Opti enables the city to preparein advance of storms.
By using continuous real-time data, Optihelps verify and report on stormwater assetperformance, such as discharged volume.
City of Casselberry, Florida: $2.2 billion in property sits in flood zonesand 15% of the population is 65 years or older.
Real-time telemetry, coupledwith the City’s previous modelingefforts, has enabled the City tobetter prepare for and respond tomajor storm events.
