Hi, here I have a Breakwater/Seawall Set for your coastlines. It appears in the park menu. It contains a set of straights (with and without a signalling lamp), inner corners, outer corners (all to be placed on the water tile next to the shore) and an endpiece (to be placed on land). You have to rotate the pieces to the desired orientation and puzzle together your custom coastlines. It might seem a bit complicated but it gets pretty easy and quick once you get the hang of it ;) Please note that the seawall only looks good, if the coast tile next to it is covered by another piece from the game, a street or a plaza etc. Bare land next to the pieces will leave gaps and look weird. ALternatively, you can also place the pieces back to back in order to create slimmer dams.

The Set is inspired by a Set for Simcity 4 which was made by a player named Jeronij: http://sc4devotion.com/csxlex/lex_filedesc.php?lotGET=112 However, I modeled all the pieces in this set from scratch for Theotown.

The set is, in my eyes, equally well suited for urban and for more rural or industrial settings (See images below).

Have fun!
