According to USDG, many streets can undergo a three-phase transformation : Existing, Interim and Reconstruction.  Before fully transforming a streetscape, it might be wise to include an interim phase to test out the pattern without investing the same amount of capital that would be needed to undergo the full project.

If the new pattern is accepted, a full overhaul could be implemented, including repaving, new drainage, traffic patterns, lighting, sidewalks, and greenery.
