This issue reminded me of the early debate over ROW at Regent Park - TFS was stated as the primary reason why even the narrowest ROWs are as wide as they are.

TFS are definitely an issue, in the past, (I haven't spoken to Planning about this recently) their demand was 11M curb to curb (so sidewalks/boulevards are extra).
The minimum functional requirement for two-way traffic is 6M, though some would argue for 7M (3-3.5m per lane). That minimum presumes no on-street parking.
Looking up to the chart I posted, travel lane + parking appears to be allocated at 9M, so they seem to have reduced the TFS demand, at least a little. (Local Street - Sidewalk plus Planting Zone shows as 11M, out of a 20M ROW)
