Why Change Approach?
25 Avoid Shirk Interchange ROW uncertainties01
Address hydraulic inefficiencies02
Optimize use of funds03
Increase design options for scenic setback04
01 Avoid Shirk Interchange
UncertaintiesThe future footprint of the Shirk and SR-198 Interchange is still uncertain. 26 02 Address Hydraulic
Inefficiencies
27 03 Optimize Use of
FundsThe linear expansion of the basin as a passive open space has 2 fund sources:
28 04 Increase Design Options
for Scenic Setback Linear expansion of the basin will severely restrict aesthetic design options
29 Comparison of the Two Alternatives
with the Current Approach
Increase design options for scenic setback
Optimize use of funds
Address hydraulic inefficiencies
Avoid Shirk Interchange ROW Uncertainties
