Local Project Evaluation

Picture
​Client: Hillsborough County​

​Year: 2019 - 2020
​​
About: 
LAGO was the prime contractor for this effort to propose and evaluate a stormwater management local improvement project at W 124th Ave in Hillsborough County.​
​Applied Skills:
  • Geo-spatial data management
  •  H&H Modeling: Data collection, processing,
  • conceptualization, & setup
  • Design storm Simulations
  • Flood mapping
  • Scenario evaluations
  • Level of service
  • Cost estimation​​
​
Consulting Areas:
  • Stormwater management​

Software Applied: 
  • ArcMap
  • ArcHydro
  • Fill Sinks Plus
  • HC-SWMM5
Specifics:
LAGO was responsible for updating and refining the watershed SWMM5 model for Curiosity Creek that contain the project area. The refined model was verified to reproduce the stage and flow hydrographs recorded during Hurricane Irma (on September 2017) at the USGS monitoring station located downstream of the project area. The refined model was applied to evaluate the performance of over a dozen flood mitigation scenarios for this project. ​The proposed improvement projects included the excavation of vacant areas to create more storage that would reduce the peak flows and the upsizing of road crossing culverts to decrease the head drop at the crossings.
​
Outcome:
A scenario was found that significantly reduced peak stages at the project area and along the creek, i.e., without causing adverse impact on downstream flood levels. LAGO developed probable cost estimates for several of the scenarios tested. The scenario that produces the biggest flood improvements has also the highest estimated cost.
