The FBI Jacksonville Field Office is located on an 11-acre parcel in south Jacksonville, Florida. RS&H was retained as the civil engineer of record to design the master stormwater, grading and drainage plans, and permit with the City of Jacksonville, the Jacksonville Electric Authority and St. Johns River Water Management District. This was a LEED project, which attained a Gold rating. RS&H utilized Civil 3-D for the mass grading design to balance the site in conjunction with using geogrid for stabilization. Multiple revisions to the site grading could be performed while maintaining the stormwater conveyance system operation during the design, which resulted in a very economical site development.
