Document Description
The Contra Cost County Flood Control and Water Conservation District proposes to expand an existing detention basin (Oakley) and construct a new detention basin (Trembath), both located along East Antioch Creek in East Antioch Creek Watershed (Drainage Area 56), to provide 50 yr flood protection to areas downstream of Highway 4 and to reduce the threat of flooding in Lake Alhambra (located ~0.6 mile downstream). Prior to constructing the detention basins, the Distric tneeds to acquire property rights from non-District-owned properties located within and adjacent to the basin areas, which are subject to temporary inundation during storm events. Specifically, the District will obtain flowage and drainage easements which will legally allow the District to construct and maintain these basins and associated drainage structures to ensure that floodwaters can flow through and to ensure there will be no developments or encroachments that would impede flood flows.
