Costa Azzurra
I love this map and so will probably you. It features beautiful beaches, mountains, rivers, hills, forests, farmlands, interchanges, bridges, viaducts, winding coastal roads, roundabouts, rail lines, castles, ports, etc. It’s designed to be super playable and to not require more than 9 tiles to build a realistic city on it (pictures show my suggestions for unlocking). Hills and headlands together with the large amount of water keep the immersion of a realistic endless coastline and create good looking horizons from nearly any spot on the map.
This map is based on terrain heightmaps of Savona, Italy, along the Ligurian coast. I used a heightmap from https://heightmap.skydark.pl. The name Costa Azzurra is supposed to mean "Blue Coast" in Italian and Is a reference to the Côte d’Azur, just across the border in France. The making of this map has been documented in the first four parts of this video playlist.
Only requirement to play is the Mass Transit DLC. This is due to the 2-lane highway networks and monorail tracks used for the custom bridges. I have also setup Intersection Marking Tool and TM:PE for junctions and interchanges map wide so if you use these mods that should be in your game already. The mods are not required but I would recommend them. Same goes for Fine Road Anarchy mod which will make it easier for you to edit some of the original highways.

For the screenshots I have mostly used the Laviante LUT and the Vanilla Temperate map theme. A selection of other themes are showcased above. I have been made aware that the Oceania Map Theme also works really well with this map. A screenshot of my Relight settings is also provided, although, keep in mind that I use other mods that also affect visuals such as Daylight Classic, Cubemap Replacer, and Clouds & Fog Toggler, so the map may look different in your game even if Relight, theme and LUT is setup the same way.
I have used alot of trees on this map. About 246 761, give or take, which is rather close the the vanilla tree limit. This could affect performance if your computer isn’t up for it. The rivers on the map may act a little wonky because of how small and shallow I made them. I have put in multiple water sources along the path of the rivers to mitigate this but in turn, that may cause issues if you try to dam the rivers in some locations. I have tested dams upstream in the mountains and it does work fine, however, power production will be relatively low so its not gonna be a very efficient source of electricity. There is no underwater/seafloor detailing on this map. I did not deem it neccecary or worth the effort this time around.
Thanks to everyone who supported me or helped inspire me to make this map. In no particular order, I’d like to thank mayorwont who got me looking at the Ligurian coastline a lot more, AvoirRev and erKrieger who helped me with artwork designs and ideas, ACanadianMoose_ who helped hype up people about the map and finding good themes for it, E6GSY for finding the last rough details so that I could attend to them. A final specialest thank you is resreved for WolfGirlGaming64. Watching and listening to your first impressions of the map made all the effort worth it.
