Simple answer:

Because they didn't have enough land for an Executive course on those areas...

The southern area along Morse/Meggison is VERY narrow and with the Southern Oaks course taking up so much space, there simple wasn't enough land for more executives.

The area with more land mass (Marsh Bend, Fenney, De Luna) has what 5 Executive courses?

Now that they're expanding west and south of the Turnpike, there are huge tracts of land that can handle more golf courses. Three (a championship, an Executive and a Pitch & Putt) are scheduled to open later this year, with more already scheduled or under construction...
