It is natural for atolls to be placed near coastline? I may be wrong but the middle of oceans is where you can see atolls.
To improve coastal area just give more fishes or add new resources such as crabs.
Secondly, more fun will be if atolls are varied visually and functionally. Some provide more gold (even culture!), others help in production etc.
