  • Rock Creek Lake (CEMVR-RD-2023-277)

    Expiration date: 6/7/2023

    The applicant proposes to stabilize the bank of Rock Creek Lake by placing rock armoring along the shoreline at 57 locations for a total distance of18,510 linear feet. Most of the riprap is new and will be placed along the shoreline on a 2:1slope with the toe at a depth below ordinary high-water mark between one to three feet. The riprap will be placed one to three feet below pool elevation. No bank reshaping is required. All disturbed areas will be seeded, mulched, and fertilized. The applicant has stated there are no impacts on existing wetlands, no borrow areas, stockpile and staging will occur in existing gravel parking lots, there will be no tree clearing, and existing trees will be preserved and worked around with small equipment. There is no borrow areas needed for this project and the riprap will come from a limestone rock quarry. The purpose of this project is to stabilize the shoreline of Rock Creek Lake

  • Union Pacific Railroad (CEMVR-RD-2019-1371)

    Expiration date: 5/3/2023

    The proposed project includes the removal and replacement of an existing railroad bridge across the Wapsipinicon River at Milepost 33.31 on the Clinton Subdivision. The proposed replacement bridge will occupy the same general footprint as the existing bridge. Dimensions of the new structure will be approximately 376.5-feet in length by 36-feet in width. Temporary bridges will be constructed to the north and south of the existing bridge for construction equipment access and will be removed upon project completion. An existing roadway off of US Highway 30 will be used, however, it will be permanently widened to accommodate vehicle and construction equipment access. Equipment/material staging will be located in a fallow agricultural field located to the southwest of the bridge. Construction of the new bridge will include temporary cofferdams, grading, and the installation of two new piers as support structures. Impacts from this project include approximately 0.098-acres of permanent stream impact from pier construction and 1.29-acres of temporary stream impact from construction and temporary bridges. Permanent impacts to adjacent wetlands will include 3.0total acres. Of this 3.0-acres, 2.45-acres of forested wetland will be temporarily impacted by construction and converted to emergent wetland after project completion. Though temporary, this conversion will be counted as a permanent impact due to the loss of functions and services. The remaining 0.55-acres of forested wetland will be permanently affected by fill material and will not be converted to another type of wetland following the project. Temporary impacts to additional emergent and scrub-shrub wetlands will include approximately 4.25-acres. These disturbed areas will be returned to pre-construction conditions following completion of the project.

  • Little Walnut Creek Stream and Wetland Mitigation Bank (CEMVR-RD-2023-0482)

    Expiration date: 5/18/2023

    The bank sponsor proposes to complete activities on 90 acres of publicly owned property that would result in the establishment of both stream and wetland mitigation credits. The goal of this project is to restore 2,333 linear feet of Little Walnut Creek and four adjacent tributaries to generate an initial estimate of 98,194.45 stream credits. The bank sponsor proposes to use many different in-stream methods to aid in restoring these portions of stream, including re-meandering it to restore natural sinuosity to the channel and decrease the slopes. The sponsor also proposes to improve floodplain connectivity, install floodplain benches, and improve habitat by creating wood riffles and toe wood within the stream. Improvements to the riparian buffer include vegetation management to remove invasive species and promote native species diversity. Another goal of this project is to enhance an adjacent wetland and wetland buffer to generate an initial estimate of 7.85 emergent wetland credits. A wetland delineation has not been completed on this site but will be completed prior to the submission of the draft mitigation bank instrument.

  • Missouri Stream Mitigation Method (MSMM)

    Expiration date: 5/14/2023

    REQUEST FOR COMMENTS FOR MISSOURI STREAM MITIGATION METHOD (MSMM) - The U.S. Army Corps of Engineers Districts within the State of Missouri (Kansas City, Little Rock, Memphis, Rock Island, St. Louis) (Corps) initially finalized the MSMM on March 1, 2007. The MSMM is the primary tool the Corps uses to determine the amount of stream impacts and the appropriateness of compensatory mitigation proposals for Department of the Army permit actions within the State of Missouri. This updated revision of the MSMM will enhance the Corps ability to protect the Nation’s aquatic resources, while allowing reasonable development through fair, flexible and balanced permit decisions. The MSMM was further developed and modified using best available information and scientific concepts on May 29, 2013, and the Corps is planning to update the MSMM again. Thus, the Corps is requesting public comment on the most recent draft version of the MSMM.

  • Muscatine Island Levee District–Economic Development Administration Funded Levee Superiority–Muscatine, IA Funded Hardened Controlled Overtopping Structure (Public Notice ID #2021-0014)

    Expiration date: 5/17/2023

    In compliance with 33 USC 408 (Section 14 of the Rivers and Harbors Act of 1899; hereinafter Section 408), Economic Development Administration and Klingner & Associates PC request permission on behalf of Muscatine Island Levee District to modify the Muscatine Island Levee, an existing federally authorized FRMP. The existing Muscatine Island Levee District FRMP consists of approximately fourteen miles of earthen embankment, mainstem, and tie-back levees. Muscatine Island Levee District proposes a Levee Improvement Project on a three-mile reach of the mainstem levee (Feature 1, Figure 1), to be funded by the Economic Development Administration, and a Hardened Controlled Overtopping Structure at the downstream end of the levee (Feature 2, Figure 1).

  • City of Waukee (CEMVR-RD-2023-371)

    Expiration date: 5/9/2023

    The Applicant has proposed to construct a new 22-acre impoundment for regional storm water management. The new pond will involve the excavation of 295,000 cubic yards of soil throughout the stream channel and ponded are which will allow the area to reach the depth needed to attain the storage goals. A new 434-foot-long pipe will be installed underneath 6th Street to allow the passage of water and at the end a rock splash basin will be built to dissipate the energy of the water. The side slopes of the pond are proposed to be at a 3:1 slope.

  • Illinois Department of Transportation - District 6 (CEMVR-RD-2022-1617)

    Expiration date: 5/3/2023

    This project consists of removing and replacing the structure (SN 009-0001) that spans over the Illinois River and Curry Lake as well as the reconstruction of the roadway approaches and the 6th Street/US 67 intersection near Beardstown, IL.

Unit 1 will be 64 inches web plate girders, Unit 2 will be 128 inches web plate girders, and Unit 3 & 4 will be 82 inches web plate girders. The substructure will be drilled shafts. The total length of the structure will be 3,563 feet to 9 inches. The existing structure will be demolished after the proposed roadway and structure are constructed and open to traffic. Riprap will be placed for erosion control and scour protection.
