Environmental Assessment: PL 84-99 Levee Rehabilitation Program Lower Platte South Natural Resource District, Antelope Creek, Lincoln, Lancaster County, Nebraska
Abstract
In accordance with the National Environmental Policy Act and implementing regulations, an Environmental Assessment (EA) has been prepared to evaluate the effects of the proposed Levee Rehabilitation Project along Antelope Creek, Lincoln, Lancaster County, Nebraska. The EA was prepared to determine if the proposed scope of work and associated impacts would result in any significant impacts to the human environment. The proposed project consists of reshaping the existing levee banks back to a 3:1 slope and replacing lost riprap along portions of the right and left descending banks. Three alternatives were considered: Structural Repairs, Nonstructural Repairs, and the No Action Alternative. Under the Preferred Action (Structural Repairs Alternative 3), the necessary rehabilitation to the Lower Platte South Natural Resource District s Flood Control Works will be preformed and the levees will be returned to pre-disaster conditions in order to provide flood damage reduction. The No Action Alternative was considered and not selected because it would not meet the projects purpose and need, which is to repair the flood control works to pre-disaster condition in order to provide flood damage reduction. Alternative 2 (Nonstructural Repairs) was not selected because under the PL 84-99 Program, this alternative must be requested by the project Sponsor. On October 30, 2014, the project Sponsor sent a letter to the USACE s Natural Disaster Program Manager stating that they do not wish to pursue the option of a Nonstructural Alternative. The environmental consequences of the proposed action on the physical, biological, and cultural resources have been evaluated.
