to their parking or the parking spaces that they lease to Margaritas. VHB landscape
designers will also provide preliminary design jor the “parklet” near the PanAm bridge and
will design the railings and plantings along the path. VHB will work seek input from Lumen
and F&T on likely lighting design along the path and at the park. VHB will rely on the City
for negotiating any swapping of parking spaces or land between the City and BAE.

2.12.14 - PanAm Bridge Ped Walkway Rehabilitation
VHB’s initial assessment of the existing pedestrian walkway on the bridge is that the long
RR timbers that support the walkway may not meet current pedestrian loading guidelines.
VHB will reach out to PanAm to determine what their plans are for the bridge and to
obtain any records on the walkway construction and maintenance. To establish a definitive
determination on the structural adequacy of the supporting members it would be
necessary to perform a bridge inspection using a track mounted cherry picker type vehicle
that will allow VHB engineers to suspend under the walkway and the bridge to measure
the timbers and assess their condition. This would also require approval from PanAm and
obtaining one-time insurance coverage for the activities. An allowance for the track
mounted inspection vehicle and the railroad insurance is included tn this amendment. A
detailed structural design scope is attached as an exhibit.

2.12.15 - South Side Trail Improvements
VHB will develop the 3D design of the trail along the top of the riverbank. The presence of
asbestos will be assumed for the entire area, and VHB will design the improvements so
excavation will be limited. Techniques such as driven fence posts and light poles will be
explored. The design will not include tree plantings due to the steep slopes and asbestos
related restrictions. Our understanding ts that the City's landscape contractor will grind
stumps and loam and seed the slopes in the area in 2020. The need for additional
plantings is not known or included in this scope.

wide paved path on earth fill that is supported by a concrete block or similar retaining wall.
