Legislative Newsflash – Are You Ready to Comply with MWRD’s Watershed Management Ordinance (WMO)?


Legislative Newsflash
February 27, 2015

NAIOP Chicago has been tracking the MWRD’s Watershed Management Ordinance (WMO) since early 2013 issuing two letters of concern on the potential development impacts of the Ordinance which establishes uniform, minimum, countywide stormwater management regulations throughout Cook County. Passed in May 2014, the WMO’s one year grace period, for those projects that were “in process” and “grandfathered in”, will expire May 1, 2015.

To educate our members on the Ordinance as well as promote the resources available to assist in fulfilling requirements, filing permits, and understanding enforcement rules, NAIOP Chicago has provided the following links:
