Overwater Drive<br />
1.0 Architectural Description<br />
1.1 The Overwater Drive is the first <strong>of</strong> two central Pier<br />
structures that make up the new Pier. The Overwater<br />
Drive allows pedestrian, service vehicle and emergency<br />
vehicle access to the Marina and Promontory, extending<br />
from the northern end <strong>of</strong> the Welcome Mat east over the<br />
water to the Promontory. Along its length, two pathway<br />
balconies are provided for shade and relaxation. A<br />
tram stop that also serves as a turnout for emergency<br />
vehicles is provided adjacent to the Marina. The shading<br />
amenities on the Overwater Drive respond to the Pier<br />
Advisory Task Force’s recommendation <strong>of</strong> creating<br />
“comfortable and attractive pedestrian walkways and<br />
pathways” to ensure that “the Pier will remain a fully<br />
integrated experience into the existing fabric <strong>of</strong> the<br />
downtown urban core, park and waterfront” (Appendix<br />
H: Pier Advisory Task Force Report, p. 12).<br />
