Elevating Assets

What is it?

Relocation of MDOT MTA assets may be evaluated in cases of high and very high risk of inundation. Simply put, this measure involves relocating the asset above the threat of rising waters. Implementation of this measure should first be analyzed for the affordability, constructability, impact, and most of all reduction to risk from flooding. Understanding the structural constraints and feasible design strategies will help ensure the viability of a specific asset identified as very high risk. Factors such as foundation type, soil type and bearing capacity, weight of the building, lateral forces on the structure, structural condition, and height of the desired elevation above grade, determine the feasibility of elevating the structure.
