That also depends on the location. In a residential neighborhood, that might be too much retail, but in Times Square it might be appropriate. There are walkable low-rise neighborhoods in Queens where the main drag is all 1-3 story buildings with retail in the ground (and sometimes second) floor and sometimes apartments above the retail. Meanwhile, around the corner are entire all-residential blocks. This works and is still walkable because getting from all-residential to retail is just a quick walk around the corner.
