Assignment
Jones Creek is a primary urban tributary to the Loxahatchee River that receives stormwater runoff from commercial, industrial and residential areas within the town of Jupiter. Over the many years of development within the 1,600 acre Jones Creek Basin, the creek has also received runoff from numerous construction sites, as well as runoff and groundwater flow from residential areas previously on septic tanks. This resulted in considerable deposition of organic and inorganic material. The restoration effort included the removal of approximately 4,500 cubic yards of sediment, a source of pollution to the Loxahatchee River.

Our Role
In June 2007, Golder Construction Services, Inc. served as prime contractor for execution of the dredging project to restore Jones Creek to historic depths, providing for a more stable benthos and reduction of sediment loads into the Loxahatchee River. The project consisted of preparing a dredged material management area for staging and dewatering excavated creek sediment, dredging approximately 4,500 cubic yards of material from Jones Creek, corresponding with local and state regulatory agencies regarding compliance with applicable Florida Department of Environmental Protection and US Army Corps of Engineers permits, performance of pre- and post-bathymetric surveys of the creek to develop a 3-D model of the creek bed from which representative cross-sections could be derived, and removal and disposal of trash and debris that had accumulated along the bottom of the creek.
