DOWNERS GROVE – Downers Grove village staff released a comprehensive, 103-page report Monday summarizing the April 18 storm that flooded more than 1,000 properties in town and overwhelmed storm sewer systems throughout the western suburbs.
The summary and analysis gives key findings, preliminary recommendations for future improvements and maintenance advice for the storm water management system. Village staff and consulting engineers analyzed information provided by residents and business owners through personal meetings, photos, emails, surveys, and videos to prepare the report, according to the village.
In July, the village will host public meetings to discuss the findings and collect additional input. A final report with recommendations will be completed in August, in time for the 2014 budget process, which begins in September, according to the village.
Among several other preliminary recommendations, the report advises the village to continue making improvements planned in the Community Investment Program. It also recommends buying houses in flood plains and demolishing them, in addition to acquiring land for flood storage.
The report also urges the village to consider regulatory changes that reduce runoff and demand on the system, such as prohibiting sump pump and downspout connections to the system.
According to the report, the 26 storm water management projects – built at a cost of more than $20 million between 2008 and 2012 – worked as designed and reduced the amount of flooding in the areas they serve.
