I don't know your budget but there are all price ranges in there. I live in Lakewood Forest an older subdivision with bigger homes and bigger lots (but my house is 30 years old). Not all of LF is in Tomball ISD. Lakewood Grove is nice and still has some new construction. Villagio is a small gated community that actually boarders the school and has a gated entry directly to Lakewood but it's pricey. The school itself in the Gettysburg subdivision.
Attendance to Willow Creek is north of Spring-Cypress road. There is a new gated community under way called Treeline. But there are a lot of recently built communities that attend Willow Creek, I just don't know them. They are mostly along Spring Cypress road.
I don't know much about the new elementary called Canyon Pointe. It's just to the north of Willow Creek. It's in the Norhtpointe subdivision and may be worth driving around and looking at. It will open this fall under the hand of Lakewood's principle. She is highly regarded and was asked to start up this school. Lakewood's VP will be taking over for her and she is very capable too.
I just found this link on the TISD web site. It lists the attendance boundaries and subdivisions that attend every elementary. Good Luck!
