Helicopter Flight Zone
The attached diagram represents our intent to provide an 80 foot wide "helicopter flight
zone" along the southwest property line of Airpark Village.
It is intended that the "helicopter flight zone" would be restricted to only allow the
following:
• Local streets;
• Alleys;
• Yards;
• Open space;
• Vehicle Parking Lots;
• Shrubs and ornamental trees.
Specifically the "helicopter flight zone" would not allow:
• Buildings;
• Canopy shade trees.
Please see the attached diagram. Note that the "helicopter flight zone" is represented in
green hatch, and the existing heliports are depicted with a red dot.
Avigation Covenant
Please see the attached draft language of an easement that would ensure the helicopter
operators that future purchasers will be aware of the existence of helicopters in the
vicinity, and that the helicopters will continue to operate in the vicinity without
interference from said future purchasers.

Paul,
Regarding the Airpark Village project, I'm not sure if you ever got a copy of this
avigation agreement regarding the helicopter noise for the plan amendment packet
several months back, but if not, here it is for your information.
