Key Points Regarding the Permissibility of an Eruv in Brooklyn According to Rav Moshe Feinstein zt”l

Even Rav Moshe’s chiddush, which was his personal opinion and not a p’sak for others, does not preclude the establishment of an eruv in Brooklyn for the following three reasons:

• The population of the entire Brooklyn with the people who commute into the borough to work is much less than the 3,000,000 inhabitants required by Rav Moshe.
• Even if the total population of Brooklyn would be more than 3,000,000, since the eruvin erected in our neighborhoods encircle a population of much less than shishim ribo, Rav Moshe would have allowed an eruv to be erected in our neighborhoods in Brooklyn.
• Even if Brooklyn would have a population of 3,000,000 and the eruv would encircle more than shishim ribo, since there are mechitzos encompassing Brooklyn, Rav Moshe would definitely have allowed an eruv to be erected in any neighborhood in Brooklyn, without the need for delasos at the pirtzos.

It is important to note that, according to Rav Moshe, even one of the above conditions would be sufficient reason to permit an eruv of tzuras hapesachim.
