The Wall You Can See But Can't Have

Norfolk's $2.6 billion federal floodwall protects downtown and Ghent while Berkley's majority-Black Southside โ€” the city's most flood-exposed ground โ€” receives a study budget and a view of the barrier that won't protect them.

Layer 1 โ€” Human Becoming

The Line on the Map

Kim Sudderth has lived in Berkley her whole life. She knows which streets drain first and which ones don't drain at all. She knows which neighbors have started stacking sandbags before the rain even begins โ€” not because they're catastrophizing, but because they've been through this enough times to know the window is narrow. She knows, when a storm report comes in overnight, that her street will probably flood. Not might. Probably.

So when the Army Corps of Engineers released the boundary maps for the Resilient Norfolk Coastal Storm Risk Management Project โ€” a plan nearly a decade in the making, worth $2.6 billion, designed to protect Norfolk from the sea it is slowly sinking into โ€” Sudderth was paying attention. She found the map. She traced the red line. And the red line stopped at the Elizabeth River's Eastern Branch. North of it: a physical floodwall, eight miles of engineered concrete, designed to protect downtown, Ghent, the Freemason district, Lambert's Point. South of it: Berkley. Campostella. Campostella Heights. Elizabeth Park. The neighborhoods where she and her neighbors had been paying off their mortgages for decades, raising families, attending civic league meetings, planting gardens behind houses they owned outright.

No wall. Just a designation called "Phase 5 โ€” Non-Structural Measures." Home elevations. Basement fills. Buyouts.

"My first thought was, 'Oh God, it's happening again. And it's happening to me,'" Sudderth said later. She became a planning commissioner. She showed up at City Hall. She organized. And three years after that map went public, the result is $500,000 โ€” not to build anything, but to fund a study of whether the wall might, one day, be extended to the Southside. The study will take three years. Then there will be design phases. Then funding. Then construction.

In the meantime, her street floods during just about any storm.

She can see the wall from her shoreline. She just can't have it.

Layer 2 โ€” Structural Read

The Cost-Benefit Formula That Redlining Wrote

The mechanism here is not new. But its application in Norfolk has a precision that deserves specific analysis, because it is not the result of individual bias or political neglect โ€” it is the product of a technical methodology operating exactly as designed, on inputs that were corrupted decades before anyone drew the floodwall boundary.

The Army Corps of Engineers uses a cost-benefit framework to determine where structural flood protection is economically justified. The logic is straightforward: the cost of building a wall must not exceed the value of the property the wall protects. When the Corps applied this calculation to the Southside in its 2018 evaluation, the math did not close. The homes in Berkley, Campostella, and Campostella Heights โ€” majority-Black neighborhoods on Norfolk's south bank โ€” were worth less than the infrastructure required to protect them. Therefore: no wall. Non-structural measures only.

Structural Note

The Army Corps cost-benefit methodology uses property dollar values as the primary measure of what a wall is "worth." Johnny Finn, Associate Professor of Geography at Christopher Newport University, has documented that for every one percentage point increase in Black residents in a Norfolk neighborhood, home values drop $700 โ€” even after controlling for household income. A neighborhood that is 100% white versus 100% Black, same income levels, represents a $70,000 difference in home value. The Army Corps formula did not create this disparity. It inherited it from decades of federal redlining โ€” and then used it to determine who deserves structural protection from federal climate infrastructure. The methodology was neutral. The inputs were not.

The Resilient Norfolk project is organized into five phases. Phases 1 through 4 cover the city's northern and central neighborhoods: downtown, Ghent, Freemason, Chesterfield Heights, Lambert's Point. These receive the physical wall. Phase 5 โ€” the Southside, covering Berkley, Campostella, Campostella Heights, Elizabeth Park, Ingleside, and Willoughby โ€” receives "non-structural measures." The Resilient Norfolk project documentation uses language like "reducing damages" for Phase 5, as opposed to the more direct "preventing flooding" language used for the walled phases. The distinction is not semantic.

Community organizing did force movement. Lawrence Brown, president of the Campostella Heights Civic League, made the comparison explicit: "Most people that live over here, they are retired, they got their home and they paid it off. And now somebody comes in and tells them that they may have to come in and fill the basement." Brown drew parallels to the post-Katrina buyout pattern in New Orleans โ€” federally-funded acquisitions that ended communities rather than protecting them. Sharon Hendrick, president of the Campostella Civic League, organized a sustained presence at City Hall. Skip Stiles of Wetlands Watch mapped the project's structural gaps in public testimony.

Structural Note

The Climate and Economic Justice Screening Tool (CEJST), used under Biden's Justice40 initiative, places all Norfolk neighborhoods south of the Eastern Branch of the Elizabeth River in "disadvantaged community" status. The Berkley census tract specifically ranks in the 91st percentile for projected flood risk from combined tidal, rainfall, riverine, and storm surge exposure over the next 30 years. This means the Army Corps cost-benefit calculation excluded structural protection from the city's single most flood-vulnerable community โ€” not despite its risk profile, but because decades of suppressed property values made the math unfavorable under a framework built on property values.

The $500,000 earmark secured in February 2026 by Representative Bobby Scott represents the result of three years of sustained community pressure. Scott's stated rationale was direct: "People have a lot of investment in their homes and should not be disadvantaged just because they live in a low-income area." The earmark funds a Post-Authorization Change Report โ€” a formal Army Corps process to reassess whether the Southside wall extension is now justifiable. That report will take three years. After that: Army Corps Headquarters review, potential Congressional reauthorization, design, and construction funding. The earliest plausible date for structural protection in Berkley is the mid-2030s. Norfolk is sinking faster than that timeline moves.

Layer 3 โ€” Pattern Confirmation

The Geography of Sacrifice Zones Is Not Random

What is happening in Norfolk is not exceptional. It is the most precisely documented instance of a pattern that environmental justice researchers have been tracking for decades โ€” the convergence of historical racial geography with federal climate infrastructure investment, producing outcomes where the communities that carry the highest physical risk receive the least structural protection.

The data from Norfolk itself confirms the disparity at the operational level. A peer-reviewed study published in November 2025 โ€” funded by the National Science Foundation, led by researchers including Lerma et al. at the University of Virginia โ€” analyzed five years of 311 flood service requests in Norfolk (October 2019 through December 2024). The finding: census tracts that are predominantly Black report 56.25 flood incidents per square mile. Predominantly white census tracts report 45.51 per square mile. This 24% gap in flood burden exists in a city where the Army Corps methodology determined that Black-majority neighborhoods were not worth structural protection.[1]

The physical context compounds the inequity. Norfolk sits on subsiding glacial sediment. A February 2026 Virginia Tech study, tracking Hampton Roads across five years of GPS measurements, confirmed the region is sinking at an average of two millimeters per year โ€” with some Norfolk locations exceeding five millimeters annually. Combined with accelerating sea-level rise, Norfolk experiences one of the fastest rates of relative sea-level rise on the entire East Coast. NOAA data documents a 325% increase in nuisance flood events since 1960, with projections showing further acceleration to 2050.[2]

The broader research context is equally clear. Across American coastal cities, federal flood infrastructure investment has historically concentrated in higher-income, whiter neighborhoods โ€” not exclusively through explicit discrimination, but through the compounding logic of cost-benefit frameworks that use property values as their core metric. A neighborhood that was redlined in 1940 has lower property values in 2025, produces a lower cost-benefit ratio in 2018, and therefore receives non-structural measures in 2026. The mechanism does not require individual racism to operate. It requires only that no one intervenes to correct the inputs.

The Army Corps' own language acknowledges this. In 2023, Resilient Norfolk's official documentation stated: "Based on inputs from the southside community members, the city and the USACE recognize the criteria from the initial study was not comprehensive in all the factors impacting this community." That acknowledgment has not produced a wall. It produced a study budget and a three-year timeline.

The signal: when federal climate adaptation infrastructure is allocated using property-value cost-benefit frameworks in cities with documented redlining histories, the communities that bear the highest physical risk will systematically receive the least structural protection โ€” and the process for correcting that outcome will unfold across timelines that exceed the rate of physical deterioration.

Alternative Explanations

Alternative 1 โ€” Technical Constraints, Not Structural Discrimination

One credible reading of the Phase 5 designation is that the Army Corps methodology, while producing a racially disparate outcome, was applied uniformly and technically. The Southside's geography โ€” lower-lying, fragmented by waterways, with more distributed flood pathways than the consolidated downtown basin โ€” may present genuine engineering challenges that make a continuous structural wall less feasible regardless of property values. Under this reading, the equity failure lies in the framework's design, not in any intent to exclude, and the appropriate fix is methodology reform rather than a finding of discrimination. This alternative deserves weight: the Army Corps has, in fact, acknowledged that the framework was "not comprehensive." However, the evidence does not support engineering infeasibility as the primary obstacle โ€” the study being funded in 2026 is evaluating feasibility that the original analysis foreclosed based solely on the cost-benefit threshold. If the barrier were engineering rather than economics, a study of economic viability would not be the prescribed response.

Alternative 2 โ€” Non-Structural Measures as Equivalent Protection

A second counterargument holds that home elevations, basement fills, and targeted drainage improvements โ€” the Phase 5 measures โ€” can provide meaningful flood risk reduction comparable to a structural wall, at lower cost and with less community disruption. This is the implicit framing of "reducing damages" in the Army Corps documentation. There is genuine evidence that elevation programs work at the individual-property level. However, the evidence from five years of 311 flood data (Lerma et al., 2025) shows that flood burden in the Southside's Black-majority tracts continues to exceed that of protected neighborhoods despite ongoing individual measures. The wall does not merely reduce flood damages โ€” it prevents flooding at the neighborhood level. Non-structural measures shift risk management to individual homeowners rather than to public infrastructure. The distributional logic โ€” community-scale infrastructure for downtown, individual-scale responsibility for the Southside โ€” maps directly onto the redlining boundary and is not adequately explained by engineering equivalence.

Uncertainty

What is not known: A direct, sourced comparison of Department of Defense infrastructure hardening investment at Naval Station Norfolk (adjacent to Phase 1's Lambert's Point endpoint) versus civilian flood protection investment in Southside neighborhoods has not been documented in available sources. The geographic alignment of Phase 1 with Naval Station Norfolk approaches suggests a possible secondary logic to the wall alignment beyond cost-benefit, but this remains inferential. Additionally, the specific concentration of FEMA NFIP claims by census tract โ€” data that exists at data.norfolk.gov โ€” has not been analyzed in this research pass. Direct download of that dataset would produce a powerful Tier A data point on repetitive loss concentration in Southside versus downtown tracts.

What monitoring would confirm or deny: If the 2026โ€“2029 Post-Authorization Change Report produces a revised cost-benefit ratio that now clears the Army Corps threshold without requiring methodology reform โ€” i.e., if Southside property values have risen sufficiently since 2018 โ€” this would suggest that market-rate appreciation (possibly driven by climate gentrification dynamics) is becoming the mechanism by which Southside protection eventually qualifies. That outcome would represent a new signal layer: the communities that are flooded out achieve wall protection only after the flooding-driven displacement changes the demographic and economic profile of the neighborhood enough to clear the formula. If the study instead finds that methodology reform is required, the signal of systematic structural exclusion is further confirmed.

Research gaps: No specific named storm event with a documented, comparative response disparity between Southside and downtown was surfaced in this research pass. The flood burden is chronic and distributed rather than anchored to a single disaster event โ€” which is analytically important but limits narrative anchoring to policy and data rather than incident.
