The Master Plan divides the 16 acres of the Carleen Bright Arboretum into four major zones of related function & visitor experience. Sub-areas with distinct purpose & character lie within each zone.
- The Western Gardens & Whitehall Center occupy the approximate south western corner of the property & have access from Bosque Boulevard.
- The Eastern Gardens include plantings & displays within the southeastern quarter of the property between Whitehall Center & Pavilion Way (Wood Valley Drive).
- The Pavilion, along with Wedding Lawn and the Gazebo, compose roughly the middle part of the acreage & have access from Pavilion Way (Woodway Valley Drive).
- The Todd Willis Nature Trail & maintenance complex lie within the northern extent of the Arboretum & run the full width of the property.
