JPL offers specialty services in flood control planning and design, integrating engineering, hydrology, and flood plain management to analyze, mitigate, and provide viable solutions to flood control and drainage issues.

In the years since 2003, JPL engineering processed hundreds of Technical Drainage Studies through the local entities and several 6-separate CLOMR/LOMR's through FEMA. Onward through present day, Technical Drainage Studies have continued to be a large portion of the team's focus.

For flood planning, JPL uses a combination of hydrologic and hydraulic computer models, such as HEC-HMS and HEC-RAS, as well as more advanced, two-dimensional modeling techniques for more complex watersheds.

Modeling programs include :

As well as more traditional programs such as

Flood control system design requires detailed analysis and construction plan preparation, covering a broad range of civil engineering disciplines. These include land planning, water resources engineering, geotechnical engineering, structural engineering, and environmental permitting. Typical flood control system designs include levees, floodwalls, channel improvements, detention or retention storage ponds, storm pipe improvements, and culvert or bridge widening projects.
