I also found a district map for Parkland School District. If this is the same map you viewed that didn't have enough detail, I recommend calling the school district directly at 610.351.5503. Someone at the main office will be able to give you a more specific account of the school boundaries.
Another option is to call Springhouse Middle School at (610) 351-5700.
These resources should give you all the info you need, but if for some reason they don't, please ask a follow up question here on Noodle. Good luck!
