Pool - 24 X 24
School - 64 X 45
Hospital - 30 X 44
Police - 30 X 30
Theater - 25 X 30
Bistro - 20 X 25
Gallery - 20 X 25
Bookstore - 20 X 25
City Hall - 30 X 64
Spa - 20 X 25
Library - 20 X 25
Market - 20 X 25
Juice Bar - 20 X 25
Gym - 30 X 45
Military Base - 44 X 44
Stadium - 48 X 55
Office Tower - 24 X 24
Research Facility - 24 X 40

This is not a complete list, but I hope someone finds it useful.
Comments
Hopefully when I update River Island or Create a new world I'll remember this list, makes a lot of difference to the speed of completion
NOTE: I have noticed a difference in community lot sizes between Riverview and Sunset Valley.
