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 each of the years 2005 and 2006, JPL engineering process over 60 Technical Drainage Studies through the local entities and several 6-separate CLOMR/LOMR's through FEMA.

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, including 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.
