The agency’s own analysis
What the notice says, and what it leaves out
The window has closed; the record of what was missing stays.
The agency says
“It is recognized that the CISA defined regulatory floodplain is 11 ft NAVD88, while the seawall (replacement and extension) will be at +8.5 ft NAVD88.”
The document openly states the CISA regulatory flood elevation is +11 ft NAVD88 but then acknowledges the new seawall will only reach +8.5 ft NAVD88, a 2.5-foot shortfall below the agency's own computed standard.
The agency says
“the CISA regulatory flood elevation (BFE + SLR (rounded to the nearest foot)) would be +9 ft BFE plus 2 ft SLR resulting in +11 ft NAVD88”
The document rounds the NOAA intermediate SLR projection of 1.44 ft up to 2 ft when computing the CISA regulatory elevation, inflating the stated standard from roughly +10.44 ft to +11 ft NAVD88.
The agency says
“Site-specific sediment modeling performed during the schematic design confirmed the proposed design is not expected to alter the existing flood dynamics or result in any measurable impact to the shoreline downstream of the wall extension.”
Section 3.2 states that site-specific sediment modeling confirmed no measurable downstream shoreline impact, yet no details of that model are provided anywhere in the document: no model name, no input parameters, no output data, no uncertainty range, and no citation.
The agency says
“During a 100-year coastal storm, the water around Kingsley Plantation is expected to rise approximately +6.6 ft NAVD88 (difference between 0 ft NAVD and SWEL) alone, not including any wind-generated waves or increases due to SLR.”
The document states the existing wall was overtopped as recently as 2022 when storm surge reached approximately +6.6 ft NAVD88 SWEL against a wall top of +7 ft NAVD88.
The agency says
“Tidal flats provide unique habitat for benthic organisms, oysters, and juvenile marine life including fish as well as critical foraging area for shorebirds.”
The document says the aquatic resource delineation was conducted in December 2025 and identifies permanent loss of 0.018 acre of intertidal waters and conversion of 0.049 acre of unconsolidated shore.
The agency says
“NOAA's Sea Level Rise Viewer predicts 1.44 ft of SLR for the year 2060 (the intermediate scenario) (NOAA, 2026a).”
The document adopts a 35-year design life correlating to 2060 and uses the NOAA intermediate SLR scenario of 1.44 ft for that period.

Who holds the vote
PLAN’s record doesn’t tie a member of Congress to this fight yet. The scorecard grades the votes and bills that decide public lands; nothing joins a vote or a bill to this decision, so there’s no member to name here without guessing.
