Elmhurst Creek Sediment Removal and Maintenance Project

Elmhurst Creek Sediment Removal and Maintenance Project

The Proposed Project includes the initial clearance and ongoing maintenance of Elmhurst Creek for the next five years (until 2011) with the intention of restoring the detention and conveyance capacity of the creek and establishing a mature riparian corridor. Initial Project activities include dredging/excavation, vegetation clearing, including the removal of six trees, bank shaping, minor channel realignment, revegetation of the creek, and replacement of the existing box culvert and overlying bridge at the east end of the Project Site. Ongoing maintenance activities would include removal of refuse, debris, and detritus obstructing the creek channel, clearing of non-native, invasive, or nuisance vegetation, and minor bank shaping. The Proposed Project is primarily a clearance effort, but would involve minor realignment along the current axis of the creek. Initial dredging/excavation would remove an estimated 2,000 cubic yards of accumulated sediment vegetation. Ongoing maintenance thereafter is estimated to remove about 50 to 100 cubic yards of accumulated sediment and vegetation annually. The banks of the creek would be reshaped, as needed. The final bank configuration would be further stabilized with bank stabilizing vegetation and other bioengineering controls.
