Site constraints and grade conditions at the Prado Re-development Project created many problems for the design team. Nearly 100 feet of grade separation required 3 level multi-tiered retaining walls. The multi-tier aspect made it possible to contain the enormous change in elevations where a single wall could not accomplish the task. HGA provided the design for over 4,000 linear feet of cast in place retaining walls ranging between 8′ and 26′ tall. Portions of the retaining walls provided support to the parking structure servicing the development.
