Is the duck pond in the middle of the Passaic Park considered like זרעים / garden and is מבטל שם דירה thereby prohibiting to carry inside the entire Passaic eruv as it is פרוץ למקום האסור לו – open to area that one may not carry?

Halacha question –

Do parks or wooded areas larger that a בית סאתים disqualify a city eruv? 

Yesterday we learnt the תוספת ישנים underneath “תוספת דף כג: “איכא and the רא”ש פרק ב’ ס’ ב  “ומתוך פ’ רש”י (approximately 20 lines before end) that according to Rashi gardens only destroy דירה for a קרפף but not for a חצר
