There are a number of structure wind zone maps that come up if you search for
“wind zone tower”. It appears on all of the ones I saw, most of NY is in the
115mph zone. That said, the specific map and how it’s applied depends on which
version of the applicable code (EIA/TIA-222-[version]) how to calculate the
stress on the structure is calculated. I believe 3-second gust is the most
recent requirement, but the building code applicable to where your tower will
be located is what has to be followed.
Here’s a decent reference

Subject: [TowerTalk] New York state wind survival requirements for
antennas
Message-ID: <d0d4a12805c658027cbabcb0577aad4558992fb4@webmail>

I have a few questions regarding antenna wind survival requirements in
NY state and possibly the whole US. A local building inspector is
telling me that just like with towers, NY requires any antenna mounted
on a tower to be able to withstand a 3-second wind gust at 115 mph,
but I know that can't be right. If you have any knowledge or
experience in this area, please contact me directly at my email
address. I have not had any luck getting answers from the ARRL.
I'd also be interested to know if there is still an email reflector
for topics like this. I heard about one called "Ham-Law" but it
appears to have shut down a long time ago.
Thank you,
Gerry KA2MGE
