Lower Mission Creek Flood Control

Lower Mission Creek Flood Control

The EIS/EIR specifically addresses Alternatives 12, 6, and 8. These alternatives would increase the channel capacity to 3,400 cubic feet per second (cfs), providing a 20-year level of protection. Channel improvements would occur on approximately the last mile of the creek between the Canon Perdido Street Cabrillo Boulvevard Bridges. Alternative 12, the National Economic Development (NED) tentatively recommended plan, includes; natural creek bottom; replacement of five bridges, streamlining bedslope, installing a culvert that bypasses the oxbow; stablizing creek banks by using a combination of short vertical walls and vegetated riprap in most places with vertical walls at bridges and at other constrained locations; and construction of habitat zones and a wetland. Alterative 6 consists of: natural creek bottom; stabilized creek banks with vertical walls and vegetated stepped banks; replacement of seven bridges; streamlining bedslope; construction of habitate zones and a wetland; and the oxbow would widened to contain higher flows. Alterantive 8 consists of: natural creek bottom; stabilization of creek banks with vertical concrete walls; replacement of five bridges; streamlining bedslope; installing a culvert that bypasses the oxbow; and construction of habitate zones and a wetland. Future maintenance is an integral part of the project design for all alternatives identified above, and is included in the project description for the life of the project. Project design incorporates planting of vegetation along upper banks, within vacant remnant land parcels, and construction of a wetland. In addition, Alternative 1, the No Action alternative, is considered in the EIS/EIR.
