Conflicting Regulations
Section 16.210 Conflicting Regulations
If an apparent conflict exists between this Part and any
other regulations or ordinances applicable to the same area, whether the
conflict be with respect to the height of structures or vegetation, the use of land,
or any other matter, the more stringent regulation or ordinance will govern and
prevail. For example:
a) Differences
between the Division and the Department’s Division of Highways concerning
outdoor advertising sign placement.
b) Differences
between the Division and the Illinois Commerce Commission over a public utility
power line pole location.
