Joint Public Notice US Army Corps of Engineers Department of Natural Resources

1. Applicant: Dubuque County Conservation Board, c/o Brian Preston of the, 13606 Swiss Valley Road. Peosta, Iowa 52068.

2. Project Location: Little , Section 31, Township 89 North, Range 1 East, Dubuque County, Iowa: UTM NAD-83 Zone15, Lat: 42.482539, Long: -90.895516.

3. Project Description and Purpose: The applicant proposes to stabilize an existing 1,700 feetof vertical cut bank along the north streambank of Little Maquoketa River at the Miller/McGrath Wildlife Area. The streambanks will be excavated to a 4: 1 slope and the materials excavated will either be transported to an upland site or spread along agricultural fields adjacent to the project area. Rock riprap will be placed two feetabove and below the toe of the bank slope. Earth fill will be placed eight inches deep over the rock to extend to the water surfaceelevation. The excavated area will be seeded with native prairie and a double netted straw blanket will be installed according to the manufacturerrecommendation. Natural Resource Conservation Service (NRCS), drawings are being used but no NRCS funding or technical service is involved in the project. The purpose of this project is to minimize future erosional damage, prevent the loss of land or land uses adjacent to Little Maquoketa River due to anticipated future high water events, and minimize finesediments that are currently being washed downstream of the project area. Wetland impacts are not anticipated. Stream mitigation will not be required due to the nature of the project.

4. Avoidance and Minimization: The only avoidance measures considered by the applicant are "No Action" and "Proceed as originally planned." The applicant's project description and purpose is meant to reduce erosion and if allowed to proceed as planned should decrease sediment deposits while simultaneously increasing water quality of Little Maquoketa River. The Applicant's project plans also minimize impacts to Waters of the by applying riprap only on the north shore of the stream and not both shorelines of Little Maquoketa River within the project area.

5. Agency Review.

a. Department of the Army, Corps of Engineers. The Department of the Army application is being processed underthe provisions of Section 404 of the Clean Water Act (33 U.S.C. 1344). CEMVR-OD-P-2019-1403 - Dubuque County Conservation Board

b.oState oflowa. The project plans have been submitted to the Iowa Department of Naturalo Resources (IDNR) forstate certificationof the proposed work in accordancewith Section 401 of the Clean Water Act. The certification, if issued, will express the Department's opinionthat the proposed activity will comply with Iowa's water quality standards (Chapter 61 IAC). The applicant has also applied forauthorization of work in the floodplainpursuant to Chapter 455B of the Iowa Code and other applicable state pen:i:lits.

A copy of the comments should be provided to the Corps of Engineers office (see paragraph 11. of this public notice foraddress).

6.oHistorical/Archaeological. The District Archaeologistconsulted with the Iowa I-Sites onlineo geographic information systems archeological site and survey databases' and determined the permito area has not been surveyed. In addition, the soils survey, topo and LiDAR maps were consulted.o An overlay of the topo map and the current aerial photo the project area appears to be located insideo the active meander belt of Little Maquaketa River. The vast majority of the soil typesmaking upo the permit areato be Camp Creek deposits or even yOlmgerudifluvent soils. Based on thiso informationit is the opinion of the District Archaeologistthere will be no historic propertieso affected because "the nature, scope, and magnitude of the work, and/or structures to be pennittedo are such that there is littlelikelihood that a historic property exists or may be affected" (33 CFRo Part 325, Appendix C.3.b).o

7.oEndangered Species.o

a.oDistrict staffhas performedapreliminaty review of this application forthe potential impact ono threatened or pursuant to Section 7 of the Endangered Species Act as amended. The following all have potential habitat in Dubuque County, Iowa.

b.oNo critical habitats are listed within the project area. The project site is not on the Mississippio River, nor does it involve wet prairies or sedge meadows. So neither listed mussel species nor listed plant species should be affected. Our preliminary detenninationis that this project is "no effect"to federally endangered species or critical habitat. Weare coordinating this application with the Fish and Wildlife Servicesthrough this public notice. Accordingly, our preliminary determination is subjectto change should furtherinformation become available.
