The State of Delaware Department of Natural Resources and Environmental Control (DNREC) selected ATM to provide professional engineering, contract and construction management services for the complete reconstruction of an existing 306 slip public marina facility (Delaware Seashore State Park). The re-development project was designed to correct the severe infrastructure deterioration at the facility. ATM services included existing conditions analysis, development and analysis of design alternatives, environmental investigations, economic and feasibility analysis and Pro Forma development. In 2002, DNREC again turned to ATM to lead a multi-discipline team through project completion. Permitting and design of a 274 wet slip and 174 dry storage marina was completed in the Summer of 2003.

In addition to the marina and floating dock design, the effort included an evaluation at different methods for stabilizing the basin shoreline, and the design of two steel sheet pile bulkheads.

Phase I construction was completed in the Fall-Winter of 2003-2004. Phase II construction was completed in for Fall-Winter of 2004-2005. The dry storage building was constructed in Fall-Winter 2005-2006.
