The Village of Glenview currently has an ordinance that states the
max allowable impervious coverage for each lot in the Village, which is
based off a lot(s) square footage. For example, lots that are less than
10,000 sq. ft. are allowed 4,500 sq. ft. or .40 of impervious coverage
and the larger the lot, the smaller the percentage of impervious
surface(s.) Recently, the Village’s Development Department was tasked
with determining what percentage of lots fell outside of their allowable
amount and if this amount turned out to be relatively high, then there
are thoughts of tighten up (changing the ordinance) the allowable space.
By using GIS (Geographic Information System) the Development
Department was able to determine percentages for each lot category and
for the Village as a whole, which now gives them the capability for
future impervious lot coverage decision making.
