Mapping Rule
One Primary Plus Two Alternates
This atlas formalizes the site-review rule: each new major shipyard and each IMM/ISO yard line should carry one primary site and two alternates. The point is resilience in title, cleanup, labor, access, and political feasibility review. Existing sovereign and contractor-owned legacy yards remain fixed current facilities and do not require alternates here.
How to Use This Atlas
- Use the primary site for the main concept of operations and cost model.
- Use Alternate A when title, cleanup, labor, or port-access issues block the primary.
- Use Alternate B as the resilience lane when politics, environmental findings, or schedule risk weaken the first two options.
- Each card supports a direct satellite-view link for quick visual review of waterfront, rail, highway, and surrounding industrial context.
