Honestly, for the smaller land locked cities like Colleyville (or Addison, Farmers Branch, etc) they really do need to make a choice on whether to go high density with lots of apartments and try to attract large office development along main corridors or stay low density (while still developing commercial/retail on main corridors), make sure to develop the school system and have the lot values increase. They're centrally located enough where commutes wouldn't be awful even to DTD. If they decided to try and mix and match throughout the city, they will eventually have clashing of citizens where either the low density people force low density amendments or they move. If that happens, then low density areas lose value, city loses tax revenue and without some quick decisive actions by the city then the infrastructure and the schools will start to suffer until you start to see a sort of re-birth (like what's going on in parts or Richardson, East Dallas, etc)
COLLEYVILLE CITY COUNCIL PASSES AMENDMENT TO CONTROL DENSITY
The limit of 1.8 dwellings per acre remains in place, but will now be assessed using net density, rather than gross density — thus removing features such as roads and parks from calculations. The effect will be to slightly decrease the permissible density for each parcel, with the aim of controlling the scale of tear-down redevelopment. Council member Mike Taylor, who expressed doubt the amendments would make a meaningful difference, said, “There are no apartments in Colleyville, and there will never be any.”
