What a hillside construction project looks like here
The Upper West Side/Central Park West Historic District (designated 1990) covers CPW from 61st to 96th Street plus 68 cross-town blocks — one of the largest LPC districts by building count (~2,200 buildings).
UWS pre-war buildings like the Dakota, Beresford, and San Remo have maintenance schedules that require LPC filings for any facade-visible window replacement — co-op boards typically front the LPC application themselves.
Because Riverside Drive sits in both the UWS/CPW and the Riverside-West End districts (overlapping boundaries), any Riverside Drive facade work triggers dual LPC review — the Commission treats each district's criteria independently.

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.
He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.
That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That’s our vibe too.
