Rainfall Impacts in Lake County
Lake County has been experiencing more frequent and stronger rainfall events. Recently, the Illinois State Water Survey released updated statistical rainfall data for Bulletin 70--Frequency Distributions of Heavy Precipitation in Illinois. This new data impacts not only the residents and business owners of Lake County, but also public and private development projects. SMC will be making revisions to the Watershed Development Ordinance (WDO), a countywide ordinance that sets forth minimum requirements for the stormwater management aspects of development within Lake County
30-Day Public Comment Period Open
The Stormwater Management Commission (SMC) opened a 30-day public comment period on Thursday, June 6, to collect feedback regarding increased rainfall in Lake County. With Lake County receiving significantly higher rainfall amounts, precipitation is a critical factor on flood damage reduction, economic impact, infrastructure design and regulations, and on stormwater storage requirements for development sites.
As SMC provides guidance and recommendations on how to review development and stormwater infrastructure projects using the updated rainfall as best available data, stakeholders and interested individuals are encouraged to submit their perspectives, ideas, and concerns. The information gathered will be considered to set new standards for the WDO.
Comments may be submitted to Kurt Woolford at email@example.com until July 6, 2019.
