Attachment A - FY20 NAS Pax River Shoreline Bathmetry and Redesign (Funding Opportunity Number N400802020004) is a Department of Defense opportunity administered by NAVFAC Washington, DC that focuses on fixing a shoreline stabilization design at Naval Air Station Patuxent River (NAS Pax River), specifically along Cedar Point. The shoreline has been experiencing serious erosion for decades, with an estimated loss of about 275 feet since 1985. While previous stabilization work south of Cedar Point succeeded in stopping erosion in that direction, it also shifted the problem and contributed to faster deterioration along the adjacent shoreline and the point to the north, creating a need to revisit and update the overall approach.

The shoreline stabilization plan was originally developed in 2015 and intentionally split into three phases to manage scope and construction sequencing. Phase 1 was planned to stabilize Cedar Point itself using about 1,335 linear feet of breakwaters, along with roughly 2,358 linear feet of revetment and sills extending southwestward along the eastern shoreline up to the mouth of Goose Creek. Phase 2 then extended stabilization beyond Goose Creek with approximately 5,173 linear feet of revetment. Phase 3 was intended to continue that revetment for an additional 2,809 linear feet, ultimately tying the work into the Chesapeake Basin. At the time of this opportunity, Phase 2 had already been built, leaving Phases 1 and 3 as the remaining unconstructed portions of the original plan.

The core purpose of the cooperative agreement is to support implementation of the original multi-phase design by bringing it up to date based on real-world changes at the site over the intervening years. Since Phase 2 construction, and due to ongoing natural processes, the area has experienced changes in shoreline and structure elevations as well as changes in underwater topography (bathymetry) and overall stability. Those changes mean the remaining phases cannot simply be built from the 2015 plans without first confirming current conditions and adjusting designs to reduce the risk of poor performance, constructability issues, or unintended environmental impacts.

In practical terms, the funded work centers on collecting updated field data and converting that data into revised engineering plans for the remaining shoreline stabilization. This includes conducting surveys and bathymetric studies, re-evaluating existing site conditions for Phases 1 and 3, and redesigning the existing plans to account for environmental and physical changes over roughly the last five years. The intent is to produce updated, reliable design documents that reflect present-day conditions so the Navy can successfully implement the remaining stabilization measures and better protect the shoreline going forward.

This is a discretionary grant opportunity using a cooperative agreement instrument, categorized under Natural Resources (CFDA 12.300). Eligibility is listed as unrestricted, meaning it is open to a wide range of entity types unless further limited by additional eligibility language in the full solicitation. The opportunity was posted July 14, 2020 with an original closing date of August 24, 2020. It anticipated a single award with a funding ceiling of $109,048, indicating a targeted, project-specific scope focused on surveying, analysis, and redesign rather than full construction.
