  • SWT-2011-860 Beaver Creek ILF Site

    Expiration date: 7/26/2024

    This notice announces a proposed modification of the Terra Foundation In-Lieu Fee (ILF) Stream and Wetland Mitigation Program Instrument (August 2015) to add the Beaver Creek ILF project site within the Canadian River B Service Area.

    Public Notice

  • SWT-2023-403

    Expiration date: 5/19/2024

    This proposed bank protection project (ODOT Job Piece 34260(04)) is designed to eliminate a large scour hole within Beaver Creek that is threatening the US-70 bridge. The application is for the construction of two Turf Reinforcement Mats (TRM) with appurtenant features and rock riprap to provide a resilient channel with restored stream function to reduce erosion and instability. Soil fill material consisting of unclassified borrow topsoil would also be used for grade sloping and bedding for the TRM. The proposed improvements to Beaver Creek (scour hole) would consist of three primary components for restoration of stream channel and bed: 1) Rock Riprap, 2) TRM, and 3) Installation of Sheet Pile Structures and Cap (SPSC).

  • SWT-2021-00533

    Expiration date: 5/11/2024

    The application is for the discharge of fill material consisting of graded limestone rock into and adjacent to 2,810 linear feet of a tributary of Covington Creek (to stabilize the bank). The proposed project will also include the construction of a temporary access/low water crossing (16 linear feet) for a construction road.

  • SWT-2022-565

    Expiration date: 4/28/2024

    Project Description: The application is for the rehabilitation of the Upper Black Bear Creek No. 62 (Lake Perry) reservoir to address flood safety criteria and performance standards for high hazard potential class (c) dams as defined by the NRCS and state of Oklahoma. The dam was recently elevated from significant hazard class (b) to high hazard class (c) due to increased development and roadways downstream which would be inundated by a catastrophic dam failure event. The proposal includes the rehabilitation of the principal and auxiliary spillway structures, maintenance to the existing riprap covering the earthen dam, as well as other elements which do not require a Section 404 Permit. As a result of this work, the current normal operational elevation (conservation pool) of the lake would be raised by approximately 2.1 feet to accommodate additional water supply storage for the City of Perry.

  • Public Notice: Environmental Assessment Oklahoma River Improvements EMBARK Boat Dock and MAPS4 Pedestrian Bridge City of Oklahoma City

    Public Notice Comment Comment Period for Boat Dock Improvements runs from March 6, 2024 to March 16, 2024 Public Notice Comment Period for MAPS4 Pedestrian Bridge runs from March 6, 2024 to March 16, 2024. Public notice documents with directions to make public comment are linked below. This Environmental Assessment (EA) evaluates the effects of the proposed construction of two (2) Oklahoma River improvement projects which will modify the Oklahoma River levee (federally constructed project). These improvement projects, construction of a boat dock and a pedestrian bridge, address the need for accessibility to the river documented in the 1993 Corridor Plan.

  • Keystone Dam Safety Modification Study Public Open House Workshops & 30-day Comment Period

    30 Day comment period for Keystone Dam Safety Modification Study begins March 6, 2024 and runs through April 5, 2024 Public open house workshops will be held March 13 and 14 from 4 p.m. to 7 p.m., at the Keystone State Park Community Center 1926 S Highway 151 Sand Springs, OK 74063. This project would raise the height of the Keystone Dam to reduce the risk of overtopping during significant flooding events. This would require the raising of the dam embankments and Highway 151, and the reconstruction of the stilling basin below Keystone Dam.
