How to perfectly align shapes to a street network on a basemap?

I'm working on creating my city in CityEngine using GIS data to be as accurate as possible. I have all the lots in the city that represent individual properties and land that looks like this:

As you can see, my shapes are missing the streets. What I have done is create a basemap and use OSM to create a street network shown here:

Which works just fine on it's own. However when I try to drag the lot shapes onto the basemap, I am always slightly off center, meaning I can't orient it perfectly.

For reference, this misalignment is what i'm referring to. Of course I can attempt to correct it but it will always mess up one other side of the city. This is as close to perfect as I can seem to get.


What is a better way to properly align the street network and the shapes? The trial-and-error method cannot get me close enough. Does anyone have any better ideas?


Thank you in advance.


Bonus question:

What is the easiest way to fix these crisscrosses in the roads you see in the last picture and here:

I have them in quite a lot of places and the "Cleanup Graph" tool doesn't help much.
