Update 4:

While waiting for my experiment to complete, I moved onto other areas of the city.

The Bankside Parcel:

A highrise, intermixed Residential and Commercial area, it's the perfect transition from uptown to the new Downtown.

Some spaces have been left open for new parks or buildings.

Just east of it:

Same thing as the last parcel, except the commercial buildings are placed closer to the residential buildings.

Just north:

A more apartment-like community. It's upper class, and I'll work on more detailed decoration at a later time. 

For now, dense trees work just fine for me. As a native Sacramentan, the urban canopy is a must.

The whole thing:

With my next update, I'll start moving into the downtown area.
