Project Description
One option for wetland mitigation (when impacts exceed 0.1 acres of jurisdictional wetlands) is permittee responsible mitigation. This option requires the creation of a wetland mitigation site and the development of a mitigation plan and monitoring. Wetland impacts along Cornhusker Road between 180th and 192nd Streets for infrastructure improvements totaled 0.36 acres. Based on delineation data provided by another firm, E&A developed a mitigation plan for Sarpy County Public Works to construct a 1.44-acre floodplain wetland, enabling the County to obtain a Nationwide Permit for the infrastructure improvements.
The mitigation plan developed by E&A included grading, seeding, hydrologic analysis, creation of an upland buffer, site protection, management strategies, and performance standards. After construction, E&A completed the as-built report in 2020. E&A has since completed five years of annual monitoring to assess the performance of the site. Due to drought conditions, continued monitoring and evaluation is ongoing.
