P-3138

Expiration date: 6/3/2020

The applicant seeks authorization to conduct grading and filling operations within waters of the United States in order to facilitate access, provide water detention and additional building lots associated with the proposed residential development. The proposed project is known as Brookside Addition. The proposed residential development will include approximately 85 building lots, 3 detention basins and 2 stream crossings. Primary site access will be obtained by a road connection into Mossy Brook Drive on the southeast portion of the tract. This road connection and adjacent building lots will impact approximately 1.29 acres of existing forested wetland. The proposed development will avoid approximately 2.04 acres of wetlands located between Peruque Creek and the eastern extent of the building lots. Peruque Creek will have an approximate 700 foot riparian buffer area of no disturbance. The proposed project site is on an approximate 51.2-acre tract of land that contains both upland and bottomland land features. The upland areas have been previously disturbed. An unnamed tributary bisects the site and flows from west to east into Peruque Creek. The tract is bordered is by a large residential development to the south and large acreage lots to the north. The site is located just north of Lake St. Louis in Section 23, Township 47 North, Range 2 East, St. Charles County, Missouri. The approximate geographic coordinates of the site area Latitude 38.8201, Longitude -90.7701.

Indian Creek ILF

Expiration date: 6/4/2020

The Land Learning Foundation has requested approval for an In-Lieu Fee (ILF) mitigation project in Franklin County, Missouri. The subject site consists of approximately 41.6+/- acres and contains both sides of Indian Creek. The Land Learning Foundation refers to this project as the Indian Creek site, and the U.S. Army Corps of Engineers (the Corps) has designated this project as MVS-2019-586. The mitigation project includes the preservation and restoration of forested riparian corridor, as well as the stabilization of highly eroded and incised channel bank. A full technical description and illustrations can be found in the attached document. If approved by the Corps, the Indian Creek site will create a total potential mitigation credit release of 28,258.25 stream credits. The Sponsor would make the stream credits available to Department of the Army permittees seeking to fulfill requirements to purchase compensatory mitigation credit, in order to offset losses of aquatic functions and services. The Corps solicits your comments on the proposed mitigation project, responses are due to this office no later than June 4, 2020.

P-3137

Expiration date: 5/27/2020

The applicant seeks authorization to conduct grading and filling operations within waters of the United States, for the purpose of the creation of a recreational park with an ADA compliant asphalt trail system. The proposed project is known as Kiwanis Park – Phase 2 and is planned for the installation of a trail system with associated tributary crossings at four locations, and disc golf course. This will result in a total of approximately 40 linear feet of Buchanan Creek impacts and 0.88 acres of wetland impacts. The proposed project site is on an approximate 21.5-acre tract comprised of a previously disturbed area, which contains drainage features that bisects the site. The site is located on Trojan Circle, Troy, Missouri, in Section 35, Township 49 North, Range 1 West, Lincoln County, Missouri. The approximate geographic coordinates of the site are Latitude 38.9694, Longitude -90.9834.

P-3068r

Expiration date: 5/12/2020

This project originally went out for Public Notice on October 31, 2017, however due to length of the duration for the anticipated project and a modification of the finalized plans; You are invited to review and comment on Public Notice P-3068 The applicant seeks authorization to construct an approximate 600-foot long, earthen dam across the western end of a small valley containing an unnamed tributary to Belews Creek. Construction of the dam will create an approximately 9.03-acre lake. A 190-foot drain pipe will be placed under the dam and discharge into the unnamed tributary at the edge of the southern berm of the dam. An emergency spillway is proposed at the southwest corner of the lake and will drain northwest into the unnamed tributary, approximately 200 feet downstream of the lake outflow pipe. Construction material necessary for the dam will be excavated on-site. The revised lake plan is depicted on an aerial photograph and enclosed as Figure 2. Based on the proposed dam height and revised site plan, approximately 1,980 linear feet (LF) of the unnamed intermittent tributary will be impacted by dam construction, inundation and piping. The proposed lake will be constructed approximately 1.8 miles northwest of Hillsboro, Missouri (38.25518,-90.57924). More specifically, the proposed project is located in Section 28, Township 41 North, Range 04 East, Jefferson County, Missouri.

P-3083r

Expiration date: 4/22/2020

The applicant seeks authorization to conduct grading and excavation operations within waters of the United States to modify an unnamed intermittent tributary, for the purpose of increasing capacity, and to better manage the amount of runoff flowing through residential properties. The proposal plans for the improvements of approximately 600 feet of channel, with a modification that includes the widening and creation of a shallow trapezoidal channel, to contain 15-year and 100-year design storms. The modified channel would have a bottom width of six feet, a minimum depth of two feet, and side slopes re-shaped 2:1 (h:v). Also, approximately 184 feet of 2-3 foot tall modular block wall would be installed along the left descending bank to minimize impacts to private property. The vacant lot located at 6906 Roland Blvd. will be used as storage in the form of a floodplain bench. Additionally, the project involves 1800-feet of new gravity sanitary sewer ranging in size from 8-inch to 15-inch and the abandonment and filling of existing sanitary sewer ranging in size from 8-inch to 12-inch. The proposed sanitary sewer will run approximately along the same alignment; however, along Winchester Drive the new sewer will be placed across an unnamed tributary.
