Sepulveda Pass Corridor Systems Planning Study Executive Summary
Once the major elements and features were
identified and drawn on conceptual maps,
rough order of magnitude (ROM) cost
estimates were developed for each of the
system concepts. A survey was conducted of
other North American highway and transit
projects that could be used for comparative
costing purposes. The cost estimates reflect
the conceptual nature of the study and were
developed to be used as a high-level metric to
compare the alternatives.
Figure 14 identifies a group of similar projects
that were reviewed with a listing of project
lengths, fully-loaded agency costs and resulting
cost per mile figures. Unit costs from similar
projects—including existing Metro bus and rail
projects and the planned Alaskan Way Viaduct
freeway tunnel project in Seattle—were used as
a basis of the cost estimates. For example, unit
costs were identified for the cost per mile of
pavement, tunnel, elevated or at-grade
concept; or typical number and cost of stations
per mile for a BRT, LRT or HRT alternative.
These unit costs were then applied to each
systems concept to derive an estimated total
capital cost.
