There are no official boundries that I know of now. There was at one time a city of Preston Hollow, but was annexed by Dallas long ago...maybe 50 years or so. Rough area is 75 to Midway and Forest to NW Hwy. That's for the area, not for the school boundries not PH Elementary.

Contact the city of Dallas request that info. Here is an article I obtain from the Dallas Business Journal for you

Hi Cathy,

The approximate two-square mile area lying north of Northwest Highway, south of Walnut Hill Lane, east of Midway Road and west of Preston Road remain the essential original boundaries of Preston Hollow, which is often now termed "Old Preston Hollow."

The boundaries of Preston Hollow as defined by the schools the children attend is land to the north of Northwest Highway (Loop 12), south of Forest Lane, east of Midway Road and west of North Central Expressway (US 75).

Hope that helps,
Terri
