We don't have any maps to show because things are in the planning stages.
Rezoning for the PS 58/32 border seems to be off the table in District 15. The DoE has declined the D15 CEC's push to rezone.
There will be some kind of rezoning or other plan for the new Sunset Park Avenues School on 4th Ave. that will open in fall of 2014 in the St. Michael's School building. The grave overcrowding in several of the Sunset Park schools, particularly 169 and 94 will be addressed with 75 new kindergarten seats in this building (with growth vertically over the next years), but no plans about exactly where and how have been brought forward.
The DoE has been having "dezoning" talks in several districts around the city, including D13 (I think that their CEC may have already voted it down, but that doesn't mean that it won't come back), 14 and 17 and a few others that are out of my region in Brooklyn. It is in the interest of parents of preschool children to understand this issue. There are lots of implications to this move including, taking power from the local District CEC - Community Education Council (parents only real muscle in local school issues), the ability of parents to try for seats at more than one local zoned school, the dismantling of local neigborhood programs including making children travel out of their neighborhoods, and the possibility of the unchecked spread of charter schools (charter schools aren't evil, there just needs to be local imput and not all programs are necessary appropriate).
