TO WHOM IT MAY CONCERN: The Jacksonville District of the U.S. Army Corps of Engineers (Corps) has received an application for a Department of the Army permit pursuant to Section 404 of the Clean Water Act (33 U.S.C. §1344) and Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. §403). The purpose of this public notice is to solicit comments from the public regarding the work described below:
APPLICANT: Allen Lewis, Lt Col, PE
Tyndall AFB
102 Checkertail Way
Bldg. 36234
Tyndall AFB, FL 32403
AGENT: David Bell
Jacobs
10 10th Street NE
Suite 1400
Atlanta, GA 30309
WATERWAY AND LOCATION: The project would affect waters of the United States and navigable waters of the United States associated with the Gulf. The project/review area is located on the near Camp Eagle Road in Section 36, Township 4 South, Range 14 West; at Latitude 30.057461 and Longitude -85.524127; in Tyndall Air Force Base, Bay County, Florida.
EXISTING CONDITIONS: The proposed breakwater construction is in East Bay along the northeastern coastline of Tyndall AFB. The base is approximately 18 miles long by 3 miles wide and encompasses approximately 29,276 acres on a peninsula. The peninsula is surrounded by the waters of the Gulf and a series of barrier islands (Shell Island, Crooked Island East, and Crooked Island West) to the south, St. Andrew Bay to the west, and East Bay to the north. The proposed project area is within the Coastal Marshes ecoregion where there is a dominant presence of submerged aquatic vegetation (SAV) along the shoreline.
This project is funded by the Readiness and Environmental Protection Integration program and the National Fish and Wildlife Foundation's National Coastal Resilience Fund grant, awarded to The Nature Conservancy (TNC).
PROJECT PURPOSE: The purpose of the project is to improve the resilience of Tyndall AFB by protecting shorelines near critical base assets, attenuating wave energy, and reducing the rate of coastal erosion from sea-level rise in the project areas over time.
Basic: The basic project purpose is tidal flood mitigation and shoreline protection in Bay County Florida.
Overall: The overall project purpose is to construct a living shoreline breakwater project at the Tyndall Air Force Base, Bay County, Florida.
PROPOSED WORK: The applicant requests authorization to install six 210-foot-long oyster reef breakwater (ORB) units 158 feet apart at distance ranging between 617 and 815 feet from the Mean High Water line (MHWL). The submerged breakwater structures will be installed at least 25 feet seaward of the existing grass meadow. The ORB units will be submerged in water depths of 4 to 5 ft, with the top of each structure 0.56 ft below the current mean low water level. The majority of the ORB units and finger reef structure will be constructed from quarry limestone boulders with 2:1 side slope. The side of the finger reefs will also include precast concrete units to promote oyster colonization and provide additional structure for marine life. Each breakwater unit will cover 9,583 ft2 (0.22 acre) on the seafloor, with the six breakwater units totaling approximately 58,806 ft2 (1.35 acres). Up to three navigation signs will be installed along the outer limits of the ORB.
AVOIDANCE AND MINIMIZATION: The applicant has provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment:
Potential impacts to surface water habitats have been avoided and minimized to the extent possible while still achieving the project's purpose: minimizing disruptions to Tyndall AFB’s mission due to storm-related flooding of critical infrastructure and operational areas. Avoiding impacts to existing seagrass beds was a primary consideration during development of the proposed nature-based solutions (NBS) breakwaters. All NBS projects were designed to remain at least 25 ft seaward of existing seagrass beds. Additionally, all breakwater designs place units no less than 75 ft apart to ensure adequate flushing for water quality purposes and sufficient spacing for manatee protection.
To further minimize the impacts to the wetlands and other surface waters adjacent to the proposed impact areas, best management practices will be used during project construction. Construction of the NBS projects will be conducted from barges located 200 to 900 ft offshore, depending on the breakwater. No construction activity, including staging areas, will be conducted on land. No operation of heavy machinery will be conducted within wetlands or surface waters outside of these aerial limits. All clearing activities will take place from inside the area to be cleared. No heavy machinery or vegetation will be staged or stockpiled within adjacent areas
COMPENSATORY MITIGATION: The applicant has provided the following explanation why compensatory mitigation should not be required: “No mitigation is proposed because there are no wetland impacts.”
CULTURAL RESOURCES:
The Corps is evaluating the undertaking for effects to historic properties as required under Section 106 of the National Historic Preservation Act. This public notice serves to inform the public of the proposed undertaking and invites comments including those from local, State, and Federal government Agencies with respect to historic resources. Our final determination relative to historic resource impacts may be subject to additional coordination with the State Historic Preservation Officer, federally recognized tribes and other interested parties.
ENDANGERED SPECIES: Pursuant to Section 7 ESA, any required consultation with the Service(s) will be conducted in accordance with 50 CFR part 402. The Tyndall Air Force Base is the lead Federal agency for ESA consultation for the proposed action. Any required consultation will be completed by Tyndall AFB. As the lead federal agency Tyndall AFB is untimely responsible for compliance under section 7 of ESA.
This notice serves as request to the National Marine Fisheries Service and U.S. Fish and Wildlife Service for any additional information on whether any listed or proposed to be listed endangered or threatened species or critical habitat may be present in the area which would be affected by the proposed activity.
ESSENTIAL FISH HABITAT: As Lead Federal Agency, Tyndall AFB initiated consultation with the NMFS on EFH as required by the Magnuson-Stevens Fishery Conservation and Management Act of 1996. The proposal would impact approximately 0.22 acre of shallow water estuarine habitat with soft bottom, sand/shell, water column, and adjacent submerged aquatic vegetation utilized by various life stages of coastal sharks, penaeid shrimp, reef fish, coastal migratory species, and red drum. NMFS determination is that the proposed action is not likely to adversely affect the NMFS ESA-listed species and/or designated critical habitat.
NAVIGATION: The proposed structure or activity is not located in the vicinity of a federal navigation channel.
SECTION 408: The applicant will not require permission under Section 14 of the Rivers and Harbors Act of 1899 (33 USC 408) because the activity, in whole or in part, would not alter, occupy, or use a Corps Civil Works project.
