I used chatgpt to see if it could help. This is what i got.
It estimated the dimensions based on

⚾ Likely dimensions (approx.)
Left field line: ~280–300 ft
Right field line: ~290–310 ft
Center field: ~360–380 ft
Foul territory: very small (minimal seating + tight boundaries)
🧱 Field shape characteristics (important detail)

Instead of a symmetrical modern diamond, it likely had:

A slightly lopsided outfield (one side deeper than the other depending on street layout)
A short fence or rope boundary
Possibly temporary stands along 1st/3rd base lines
Very limited deep outfield space compared to later parks like the Polo Grounds
🧠 What that means in gameplay terms

If you dropped modern hitters into that park:

Many routine fly balls today would have been home runs
Power numbers were heavily influenced by field geometry
Pitchers often worked in compact, hitter-friendly spaces
🧾 Bottom line estimate

If we compress all evidence into a single “best guess”:

Union Street Park was likely a compact urban ballfield roughly 280–300 ft down the lines and ~370 ft to center, with irregular boundaries shaped by city streets rather than standardized design.
