The City of Lake Forest has recently been reviewing the types of
drainage available on its streets to consider new projects for the
upcoming fiscal year. As an old community, many areas of the city do not
have curbs or gutters, and solely rely on ditches or small 6’ pipes to
help move retention waters away from the road.
Cooperation between the engineering department and GIS resulted in a
map that showed streets that did not have any curbs or gutters that
could be compared with upcoming capital improvement plans. Roads were
classified as collectors, main feeders, and state arterials. Special
notes were made of streets that had combinations of ditch drainage and
non-storm sewer drainage types, and field checks on the west side of the
City insured that current GIS data was as accurate as possible
Combining road work with the installation of better drainage gives
the City an opportunity to combine projects and keep costs down. The
maps will be used as a visual aid in the upcoming board meetings to
discuss 2011 projects.
