City of Bonita Springs: ICPR Model Update. Evaluation of Hurricane Irma Flood Mitigation Projects

​​Client: 
​City of Bonita Springs
​(sub-consultant to Grady Minor)

​Year:
2018 - 2019​

​About: 
City of Bonita Springs experienced extensive flooding during Hurricane Irma and wanted to evaluate some flood improvement projects.

Applied Skills:

• Data Processing
• H&H Modeling
• Design Storm Simulations
• Flood Mapping
• Scenario Analysis 

Consulting Areas:

• Stormwater Management 

Software Applied:

• ICPR
  
• ArcMap

Specifics:
​Lago updated the City’s ICPR model by using recent DEM and permit information. The model was verified by using Hurricane Irma conditions, and it was recalibrated to better reproduce observed station data, rating curves, and highwater marks. The model was then used to evaluate 3 main scenarios with several alternatives to reduce the depth and duration of flooding in the City during extreme events.

Outcome:
Lago produced flood inundation maps, and other graphs and tables to illustrate the model performance and to support the scenario evaluation. Lago also participated in multiple discussions with City staff and addressed questions and concerns about the modeling results.
