Existing Projects Factored In Heat Map
These existing projects were retained
to add to the final deliverable. To
identify new project sites, both
sides of the street were analyzed for
constructability starting with the highest
scoring segment. Constructability
factors included: connection to existing
sidewalk, presence of curb and gutter,
existing stormwater infrastructure,
existing grade, and existing right-of-
way. Once a project was identified, these
elements influenced what timeline a
project would follow.
For example, if a project could be
implemented quickly, its timeline might
fall within the first year of the three-year
workplan. A project that would be more
complex and therefore take longer, might
have design starting in year one, and
construction in year two or year three.
This was an iterative process that
involved focused engineering to
determine project feasibility. The result
was a list for both sidewalk and bikeway
projects that outlined when and where
NDOT planned construction over the
next three years.
