MEMO TO: President and Board of Trustees
FROM: Stephen Berley, Village Manager
Dale L. Durfey, Jr., P.E.
SUBJECT: 1989 Paving Project
Stone Shoulder Policy
RECOMMENDATION: That the Village Board give direction to staff regarding if a
stone shoulder should be designed into the construction plans for
Birchwood Road, Canterberry Lane, and Robin Hood Ranch, and, if
so, what width is to be utilized.
The Engineering Department is presently designing plans for the 1989 Paving Project
which consists of reconstruction Birchwood Road and resurfacing Canterberry Lane and
Robin Hood Ranch. In the design, the question of stone shoulders is raised. In the
past, the Village has vacillated on the stone shoulder policy on different streets
at different times. In this regard, the following lists the information which we
have been able to gather concerning past constructions:

Plans. The typical rural cross section calls for a twenty -two (22') foot wide pavement
with four (4') foot shoulders.
We would like your direction on how you wish the stone shoulders to be designed for
the three (3) streets in question; should there be no shoulders, should the shoulders
be four (4') feet wide, or some dimension in between.
There are several purposes for providing stone shoulders. These include having an area
more stable than grass and dirt for vehicles which wander off or pull off of the edge
of pavement. When ruts do occur from these vehicle tires, it is much easier to repair
a stone shoulder than a grass area. Another reason for providing stone shoulders is
to provide a semi - stable area to hold the edge of pavement in place. In this case,
the stone shoulder is more stable than having a grass or dirt area immediately adjacent
to the pavement. A third reason is to effectively widen the pavement area than that
which exists with only the hard surface pavement. This give ones the impression of a
wider and safer street than if grass and dirt were immediately adjacent to the edge of
pavement.
We are placing this on the Board Agenda for April 11, 1989 for your consideration.
Respectfully submitted,
