Discussion
The City seeks to update the first floor deck area of the Airport Administrative Building
with new landscap e and hardscape . This green roof top project would renovate the
existing pedestrian walk way . H ardscape and drought toler ant landscape would be
installed in the planter areas over the recently installed water proofing membrane .
Renovations would improve the overall experience for visitors by enhancing the seating
amenities and by making the area compliant with the Americans with Disabilities Act

sustainability goals and is in alignment with City Council’s direction to enhance the
airport’s connection to the community.
