James, since Jersey City is within the huge metropolis of NYC proper, you may want to extend your search. Their might be other cities with Reformed churches less than 10-15 miles away. I notice a couple of PCA churches in Newark and one in Hoboken when I browsed the PCA directory. There might be others close by as well.
