| # Riprap — pitch cold-open (locked 2026-05-03) |
|
|
| ## Locked phrasing |
|
|
| > October 29, 2012. Hurricane Sandy floods seven subway tunnels and |
| > dozens of station entrances across Lower Manhattan and Brooklyn. |
| > The MTA's Sandy recovery program is documented in their published |
| > reports. Today, if you ask any flood-mapping tool which subway |
| > entrances near you would flood again, it cannot answer. |
| > |
| > **Riprap can.** |
|
|
| ## Why this and not the alternative |
|
|
| The earlier draft invoked a "$4.5 billion" Sandy-recovery figure. That |
| is approximately right for the MTA's *total* Sandy-recovery program |
| across a decade (per their published reports), but it's not the figure |
| for the South Ferry-Whitehall complex specifically and not for any |
| single repair. Engineering judges who know the Sandy recovery history |
| (Ramakanta Samal, the AMD solution architects, ASCE-NY engineers in |
| the room next week) will silently downgrade an inflated or imprecise |
| number. |
|
|
| The seven-tunnels framing: |
| - Is verifiable. MTA's "Storm Sandy: Two Years Later" report and the |
| 2014 NTSB-style post-mortems both reference the seven flooded |
| tunnels. |
| - Doesn't depend on a contested dollar figure. |
| - Sets up the "MTA documented this — but no flood tool can tell you |
| which entrances near *you* are at risk" gap that Riprap fills. |
| - Lands in a single sentence, not a paragraph. |
|
|
| ## Sources for fact-check |
|
|
| - MTA, "Hurricane Sandy: Three Years Later" (Nov 2015) — counts the |
| flooded tunnels and lists the affected stations. |
| - USGS Open File Report 2014-1175 — Sandy-period stage-gauge data. |
| - NYC OEM, Sandy Inundation Zone (NYC OD 5xsi-dfpx, dataset published |
| 2013) — the empirical extent that drives Riprap's `[sandy]` doc. |
|
|
| ## Discipline |
|
|
| Do not drift back to the dollar figure during the week's iteration. If |
| a different statistic gets cited in the demo or in social posts, it |
| must come from one of the three sources above (or another verifiable |
| public-record source) and must be cross-checked before publication. |
