Civic groups in South Korea have urged the Saemangeum Development Committee to reject the revised Saemangeum Master Plan, citing critical gaps in water quality management, ballooning fiscal costs, and disputed industrial land allocations. The October 28 petition follows the government’s proposal to downscale reclamation areas while expanding industrial zones.
The Bottom Line
- Fiscal Expansion: Civic organizations estimate the total project cost will reach 35.5 trillion won by 2026 and 46.34 trillion won by 2035, requiring an additional 25 trillion to 40 trillion won in public and private financing.
- Land Reconfiguration: The government’s revised plan reduces the target reclamation area by 29.5% to 169.6 square kilometers while expanding industrial zones from 18.5 square kilometers to 37.5 square kilometers.
- Environmental Friction: Opponents argue that a 12.7% reduction in dredging volume falls short of matching the scaled-back land footprint, leaving high concentrations of total phosphorus and severe oxygen depletion unaddressed.
Contrasting Metrics on Land Reclamation and Dredging Volumes
The Saemangeum Development Committee’s revised blueprint aims to recalibrate the massive coastal development project by trimming the targeted reclamation area down from 240.5 square kilometers to 169.6 square kilometers. Airports within noise-impacted zones and deep-water sectors have been officially removed from immediate reclamation targets under the government proposal.

Yet, according to figures released by the Saemangeum Permanent Seawater Circulation Movement Headquarters and the Saemangeum Residents’ Council, the corresponding reduction in civil engineering work remains disproportionate. While the land footprint shrinks by 29.5%, total dredging volume drops merely 12.7% from 7억1000만㎥ to 6억2000만㎥. The civic coalition calculates that an additional 약 3억8000만㎥ of dredging will still be required inside the Saemangeum reservoir.
Disputed Projections for Public Sector Financing and Construction Costs
Financial estimates for completing the infrastructure overhaul present a wide divergence between state planners and local civic monitors. The government’s updated framework lowers projected land development expenses from 10.45 trillion won down to 7.02 trillion won, reflecting the smaller overall reclamation footprint.
The opposing civic groups project a much heavier balance sheet burden. Factoring in inflation and expanded industrial zoning from 18.5 square kilometers to 37.5 square kilometers, they estimate total outlays will surge to 35.5 trillion won by 2026 and 46.34 trillion won by 2035. Subtracting the 9.9 trillion won already spent leaves an unfunded liability ranging from 25 trillion to 40 trillion won. At an allocation rate of 1 trillion won annually, completion could stretch across 25 to 40 years.
| Metric Category | Government Revised Plan | Civic Coalition Estimates |
|---|---|---|
| Target Reclamation Area | 169.6 sq km (down from 240.5 sq km) | Unchanged footprint; scaled down differently |
| Industrial Land Allocation | 37.5 sq km (expanded from 18.5 sq km) | Cost up to 11 trillion won for zone setup |
| Total Estimated Project Cost | 7.02 trillion won (land development only) | 35.5 trillion won (2026) to 46.34 trillion won (2035) |
| Dredging Volume | 6억2000만㎥ | Additional 약 3억8000만㎥ inside reservoir |
Ecosystem Strains and Infrastructure Debates Over Industrial Allocations
Environmental concerns center on water stagnation and toxic sediment loads. The civic groups noted that total phosphorus levels in deeper zones of the Saemangeum reservoir run five to ten times higher than the inflow rates from the Mangyeong and Dongjin rivers. Furthermore, climate projections indicating an external sea-level rise of 40 to 80 centimeters by the year 2100 led the coalition to demand that the current management water level of minus 1.5 meters be raised to at least 1 meter or adjusted to average sea-level parity.
Controversy also surrounds specific corporate land allotments. The plan designates a 700-megawatt power generation site within the agricultural-life zone for exclusive use by Hyundai Motor. Opponents argue this arrangement constitutes corporate favoritism and disrupts planned ecological buffer zones near the Haechang tidal flat and Hwashin wetland. Criticizing the lack of a concrete transmission grid roadmap for the 10-gigawatt renewable energy initiative ahead of projected 2029 power demand spikes, the coalition called for the immediate suspension of the review process and the establishment of a joint public-private consultative body.
