  • Auen Waterfowl Production Area/Blackhawk Marsh (CEMVR-RD-2022-1522)

    Expiration date: 12/10/2022

    The applicant IDNR leases this area from the United States Fish & Wildlife Service (USFWS). The proposal is to place 2,430 linear feet of bank stabilization in twenty-one locations along Carnarvon Creek. Each location varies in length from 80 linear feet to 180 linear feet, see the attachment for the site specifics. The applicants stated purpose and need is to stabilize the bank to prevent further erosion. Currently, Carnarvon Creek has steep banks on the outside bends resulting in moderate to sever erosion. The bank stabilization efforts will be along the outside bends of the creek channel. The bank will be pulled back to a 4:1 slope and armored with native field stone to a height no greater that 1-foot above base flow. The remainder of the bank will be hydro seeded with native prairie cord grass seed.

  • Osceola County Rural Water System, Inc. (CEMVR-RD-2021-0918)

    Expiration date: 12/9/2022

    This is a Supplemental Public Notice to correct an error in the initial Public Notice’s location. The initial Public Notice expired 9/31/21. The applicant proposes to construct a rock-riffle low head dam structure within the channel of the Ocheyedan River. An estimated 0.05 acres of riverbed will be filled as a result and the applicant plans to allow water to flow over the top of the dam structure during times of normal flow. The purpose of this project is to increase drought resiliency for the alluvial aquifer that supplies drinking water to the local populace. Wetland impacts are not anticipated, and stream mitigation has not been proposed due to the overall low impact total.

  • Three Mile Lake Restoration Project (CEMVR-RD-2021-1512)

    Expiration date: 11/29/2022

    The applicant proposes the Three Mile Lake Restoration Project to include in-lake sediment retention forebays, Best Management Practices (BMP’s) 1, 2, and 12, and bank stabilization along Three Mile Lake at 12 locations, including jetties, riprap, and wind breaks. Cumulatively these projects will impact 6.540 acres of open water, 7.328 acres of wetland (1.740 acres of emergent and 5.588 acres of forested), inundate 2,254 linear feet (LF) of steam (858 LF of perennial, 1,232 LF of intermittent, and 164 LF of ephemeral), and 13,025 linear feet of bank stabilization. The applicants stated purpose and need for BMP’s 1, 2, and 12 are to reduce sediment within Three Mile Lake to improve the quality of the Lake for recreational areas and to provide drinking water to 30,000 residents. Three Mile Lake has experienced decreased water quality, increased algae blooms, and impairments to fish populations in recent years. The existing silt dike has silted in, settled, and is experiencing more frequent overtopping’s. The applicants stated purpose and need for the bank stabilization is for shoreline stabilization and improved angler access due to the existing eroding shorelines. The bank stabilization efforts will provide for protection measures and angler access to existing shoreline erosion and areas in need of wind protection, angler access, and along shorelines near known sensitive cultural resources threatened from impending shoreline degradation.

  • Mar-Ops South LLC (CEMVR-RD-2022-0863)

    Expiration date: 11/24/2022

    The proposed project is located on the Illinois River approximately 1.2 miles north of Hennepin, Illinois, near the intersection of IL Highway 1 and 1150 N Road. On the Illinois River, left descending bank, mile marker 208.8 in Section 4, Township 32 North, Range 2 West, Putnam County. Datum NAD-83. UTM Zone 16. The applicant is proposing to install a replacement dock and one dolphin along the east bank of the Illinois River. The dock will be approximately 700’ long (wall facing river) with a wing on the south end and a wing going back into the bank on the north end. Approximately 6,500 cubic yards of clean aggregate fill will be placed behind river facing wall. The dolphin will be installed approximately 155’ south of the replacement dock. Mechanical dredging, excavating with a crane and clam shell bucket, will remove approximately 30,000 cubic yards of material which will be trucked to upland area. Roads to the existing dock will remain the same but new gravel or pavement will be placed prior to operation. The project will impact approximately 0.13 acres of forested wetland, trees will be removed on the southern end of the bank where the replacement dock will be located. The purpose of the project is to provide an area to facilitate loading and unloading of dry and liquid commodities on the Illinois River near Hennepin, Illinois.

  • Raccoon Valley Mitigation Bank (CEMVR-RD-2022-1343)

    Expiration date: 11/16/2022

    Project Location: The proposed site is located within Section 36, Township 86 North, Range 36 West, Sac County, Iowa.  Bank Objectives: The fundamental objective of compensatory mitigation is to offset environmental losses resulting from unavoidable impacts to waters of the United States (WOTUS) authorized by Department of Army Permits. Other Objectives include: providing economically efficient and flexible mitigation opportunities, enhance or create additional wildlife and aquatic habitat, provide additional flood retention and reduce the impacts of downstream flooding by capturing and storing high flow events, and improve water quality by reducing sediment loading and nutrients. Project Description/Bank Establishment: The bank sponsor proposes to complete activities on 79.48 acres of privately owned property that would result in the establishment of wetland and stream mitigation credits. The goal of this project is to create approximately 31.13 acres of emergent wetlands and create/enhance approximately 8.68 acres of forested wetlands by constructing earthen berms and shallow excavation that would allow water to pool in the wetlands, creating scalloped edges and an undulating bottom to ensure diverse wetland habitat. The shallow excavations will receive hydrology from disabled tile intakes, overland flow, direct precipitation, and overbank flooding from the North Raccoon River. Approximately 24.64 acres of wetlands buffer would be established around the wetland areas. The sponsor anticipates that approximately 42 wetland credits will be generated. The bank sponsor also is proposing to complete restoration work along the Raccoon River that includes creating floodplain benches and stabilizing highly eroded areas. The sponsor anticipates that approximately 21,314 stream credits will be generated. A wetland delineation was completed in the summer of 2022 and will be provided the Corps during the review process.
