Overlapping causes that flickering, so avoiding that is good too (making other object like 0.01 smaller is usually enough)
Those shadow spots appear, when you got objects too close to each other with similar center point or smth. Usually it's easy to fix for example by making other object much taller than it needs to be and sinking all that excess under ground or inside other objects. (center point is moved to somewhere else. while hiding anything that doesn't belong to map).
I took bit closer look too though. Tbh gotta say some of those spots are pretty hard to get rid of here, while keeping that fine detail. But most of it could been avoided with minor sacrifices at least. So going with bit simpler design can also help in avoiding those dark spots.
If you really need to make something with fine detail, (lot small objects close to each other) you might not be able to get rid of them at least with this method.
