Overview
The U.S. Army Engineer Research and Development Center (ERDC) seeks expert technical support and innovation to develop a new application for natural and hybrid infrastructure (NHI) technology and methodology for NHI placement in a complex landscape in the northeastern-most region of the continental United States. The goal of this effort is to identify solutions capable of reducing shoreline erosion and improving resilience through integrated NHI and conventional designs that meet performance, regulatory, and cost requirements.
Background
The site is located at Naval Support Area (NSA) Cutler in Cutler, Maine and is representative of a DoD military installation that operates in an environment that is frequently subject to extreme weather events and extreme variabilities in temperature and is located within the Gulf of Maine with a high (~4 meters) tidal range (Figure 1). This naval installation is responsible for relaying critical military communications in the Atlantic Ocean, Arctic Ocean, and Mediterranean Sea. However, weather-related events (e.g. coastal storms, storm surge, and high winds resulting in flooding and erosion) threaten the installation’s infrastructure, and the Navy must develop innovative interventions to cost-effectively reduce risks to military readiness.


The use of NHI, alone or in conjunction with conventional engineered structures, where appropriate, offers opportunities for reducing risks from natural hazards – strengthening installation and infrastructure through installation resilience. NHI also promotes sustained resilience by preserving operational capability under changing conditions and changing infrastructure needs while also protecting natural resources that are essential to the protection of the installation’s assets. While use of NHI at installations located in temperate regions of the U.S. (e.g., southeastern region of continental U.S.) has gained considerable acceptance, use of NHI at installations located in extremely harsh environments (e.g., northeastern-most region of continental U.S.) has not been pursued. Expanding applications of NHI technologies and practice, to include the extreme northeastern region of the U.S., would be advantageous for the previously stated reasons while also diversifying and expanding the arsenal of interventions that could be applied to reduce the risks from weather-related events.

Objectives
The primary objectives are to identify organizations capable of:
- Developing an innovative NHI application for the NSA Cutler shoreline that will successfully reduce impacts derived from the extreme weather events that frequent this region of Maine’s coastline. The coastline located within the project area is approximately 3.1 miles in length (Figure 2) and the total project area is approximately 170 acres (Figure 3). It is anticipated that 60% design concepts produced through this study would include, but would not be limited to:
- combinations of NHI and conventional infrastructure for the purpose of fortifying and improving the entire length of the shoreline illustrated in Figure 2;
- where applicable, innovative approaches for design and placement of culverts and/or other water conveyance features within the project area;
- where applicable, create designs for placement of repaired and/or segments of a new security road within the project area. In some instances, it’s possible the preferred alternative design may illustrate the abandonment of an existing security road with implementation of a novel approach for conducting security patrols; and
- designs that include restoration of damaged terminal anchors and/or repositioning of existing terminal anchors would be expected as part of the 60% design product. At present there are approximately 6 terminal test ends and anchors that have been directly impacted because of coastline erosion experienced at the installation. In total, there are 96 terminal end/anchors within the project area that need to be evaluated for repositioning depending on the shoreline stabilization design(s) that are selected.
- Developing innovative method and expedited path for pursuing construction of the proposed NHI through the exploration and identification of a variety of NHI geometries and forms that a) achieve Navy-approved, risk reduction thresholds and b) incorporate input from representatives of Federal and state agencies with purview over regulatory authorities applicable to NSA Cutler and the part of Maine’s coastline and waters where this NHI would be constructed (Figure 1).
- Generating estimated construction and maintenance cost for the proposed NHI and conventional infrastructure project based on 60% designs for preferred alternative.
- Completing draft permit applications for the proposed NHI and conventional infrastructure project with applicable state and Federal agencies in order to facilitate future construction of the project (construction is not included in this IPR).
While a final decision on the preferred alternative plan and design concept(s) will ultimately be determined based on several factors including, but not limited to: a) resource agency input, b) project cost, c) estimation of NHI performance, and d) projected NHI maintenance requirements, it is anticipated that the overall project design will consist of approximately 40 – 60% NHI.
Requirements
ERDC invites pre-proposals that must meet the following eligibility and other requirements:
- The applicant team shall comprise a range of competencies required for development of NHI and conventional infrastructure along with expertise to evaluate anticipated performance of the proposed intervention. Example team representatives include, but are not limited to: field practitioners with experience applying large scale NHI interventions in a diverse number of coastal landscapes and settings; scientists and engineers with experience quantifying engineering performance of NHI and conventional infrastructure; and personnel with expertise developing state and Federal permit applications (and all supporting permit application exhibits) for NHI projects to include conversations, presentations, and negotiations with respective agency representatives.
- Applicants are encouraged to submit evidence of previously successful efforts that include, but are not limited to: 1) development of NHI project concepts and designs, 2) successful acquisition of Federal and state permits in association with NHI, and 3) successful construction of NHI projects.
- Applicant team should be knowledgeable about Federal and state regulatory permitting that governs the placement of NHI and conventional infrastructure in Maine’s coastal landscapes. Knowledge and experience with procuring environmental permits for work conducted at military installations is also required.
- Development of the NHI and conventional infrastructure intervention(s) must consider existing and future conditions of Little Machias Bay and the landscape that comprises and surrounds the NSA Cutler installation.
- Applicants should submit evidence that highlight previous work pursuing innovative NHI strategies in cold regions and/or other extreme weather environments (e.g., Arctic and sub-Arctic environments).
- Applicants are responsible for conducting work under applicable laws and regulations and obtaining all necessary federal, state, and local permits for any proposed sampling or testing needed to better understand the dynamics of the Little Machias Bay and coastline at NSA Cutler. Applicants are also responsible for coordination with ERDC, responsible USACE Districts, NSA Cutler, and State of Maine agencies, and other local and Federal agencies, as required, for an assessment of environmental effects of any proposed action at the installation.
