I believe that Heatherwood Villas townhomes go to James Madison Primary and Imtermediate schools.
The Edison township Board of Education does not privide a "formal" map of school districts, and the district lines are not straighforward (they zig-zag around a bit). SOmetimes the listing Realtor does not put the schools into the listing either so sometimes it's hard to tell.
However, I know most of the boundaries (meaning streets) and if i am not sure, I always call the Board of Ed to determine if the street is in a specific school district.
Give me a call or drop me an email and let me kmow what you are looking for, and I will be happy to help you. I am a resident of Edison since 1983 and know the area pretty well.
