Policing the maintenance of private access easements which are also
typically designated as fire lanes has become a concern with the
City’s Fire Inspectors. The Department of Public Safety would prefer
that a public street be constructed in these situations, in particular,

concerns staff is proposing the following:
1) Allow a reduced right-of-way and street cross-section
requirements for subdivisions containing no more than ten
(10) lots;
2) Allow subdivisions containing no more than (4) four lots to
front on a common access easement;
3) Eliminate flag lot designs which attempt to go around the
street frontage requirements.
