All 21 tasks included permitting, and roughly half the tasks included geotechnical engineering, and hydrology and hydraulics.

Section 404/401 permitting included a waters of the U.S. delineation and report. Nationwide permits # 3 (Maintenance) and permit # 14 (Linear Transportation Projects) were submitted and obtained for each bridge from the U.S. Army Corps of Engineers. As part of the permitting process, each location was evaluated for State and Federal Threatened and Endangered Species and Cultural Resources 

Geotechnical work included subsurface investigation, collection and analysis of soil samples, and subsurface design recommendations. In addition, Shannon & Wilson analyzed existing hydrologic and hydraulic conditions, provided our design recommendations, and provided applicable permitting applications for each location.
