I tried to outline the site in red on this Google Maps screenshot:
Observations:
1) Further to the comments above, I don't think this design adds any new parking on Montgomery, which is good.
2) Further to the comments above, I actually don't mind the medium density of the casitas, because they provide a gentle transition from high density on Montgomery to low density on Owasso, one block away to the west.
3) The big garage on Byers will surely be open for paid public parking during Dickies events. Every little parking lot on Montgomery is being used for that purpose during the rodeo this month, so the demand is there. I do wish they could push the garage north toward the alley in the middle of the development, but this means vacating the alley and relocating the utility poles in it.
4) I am happy to see that the small apartments' surface parking lot in the southwest corner is being removed. Presumably those apartments will gain access to parking in the new structure or on the new north-south road.
5) I am surprised to see the new north-south road on the west edge of the design. This must be for fire code? Seems excessive; I bet it adds back more asphalt than was removed with the old surface parking lot.
