derek_gardner grass is just a graphic and shouldn't interfere with placing buildings...
Sorry, but the grass are "blockers", and nothing can be built there
If i'm not mistaken, in the middle of the 1st or 2nd street is a place to build the Meadow Station (contract #2), and for later contracts there will be room for buildings at the right of the 4th street, hidden behind the already available buildings
If i'm wrong about the 4th street, put the Meadows Station in storage and build there instead
