PROJECT PURPOSE: Rock Island District proposes to re-authorize a regional permit for bank stabilization activities for a period of 5 years to begin around October 15, 2025. The purpose of the Regional Permit is to expedite processing of a number of similar activities which will have minimal adverse impacts to Waters of the United States.
PROPOSED WORK:
1. Authorized Work Limits.
A. The following bank stabilization techniques will be authorized under this regional permit (RP): blanket riprap, seawalls, gabions, minor bank shaping with appropriate biotechnical streambank protection techniques, bendway weirs, longitudinal peaked stone riprap, stone hardpoints, channel defining structures, and grade control structures. For design projects not specifically listed, the plans must be approved by the District Engineer (DE).
B. Impacts to Waters of the United States (WOTUS) authorized within this permit shall not exceed 2,500 linear feet below the Ordinary High-Water Mark (OHWM) of shoreline for the entirety of the proposed project. If armoring opposite banks of the same waterway, you are limited to a maximum of armoring 1,250 linear feet per bank and the armoring must end at the toe of the bank to prevent channelization. Permanent loss of wetland is limited to 0.5 acres with compensatory mitigation required at 0.1 acres. Permanent wetland loss exceeding 0.5 acres shall not be authorized under this RP.
