The Village has a yearly program where its wetlands, native prairie buffers and ponds are inspected and evaluated to determine the appropriate maintenance strategy to be applied. 
 

A three year maintenance program is developed and projects are scheduled.

Wetlands serve a vital purpose by storing and filtering storm water runoff.  They generally include swamps, bogs, marshes, fens and similar areas.  Wetlands are areas that consist of certain soils, plant species and hydrology that make them unique.  Wetlands are areas that have hydric soils which are saturated by ground water at a frequency that allows vegetation that is specifically adapted for life in saturated soils.

Several maintenance strategies are utilized for Wetlands, Native Prairies and ponds including mowing, selective cutting, herbiciding, weeding, prescribed burns, trash removal, reseeding and replanting.
