Videre Woods Outfall Stabilization
Pennoni was contracted to provide stabilization of two degraded unnamed tributaries of Ball Run and Mill Creek located in Wilmington, DE. The goal of the stabilization was to stabilize the gullies, reduce pollutant, provide a functional floodplain, and enhance water quality and aquatic habitat. Pennoni provided an assessment of the gullies based primarily on physical conditions within the assessment area. A hydrologic and hydraulic analysis was also performed for the gullies to characterize the floe regime. The stabilization design considered the physical and morphological function of the gullies and incorporated natural and manmade features. The redesigned floodplain provides for non-erosive conveyance of overbank storm events (10 year and 100 year).
