Storm Water Detention Permit


A majority of building improvements result in an increase in storm- water runoff as a result of the increased impervious area from the new roof and parking areas. According to the Illinois State statutes, the storm water leaving the developed site should leave with the same intensity as the pre-developed site.

Prior to issuance of a building permit the Developer must submit a storm water detention study to the City Engineer.

The site drainage is subject to Illinois drainage law.  Storm water leaving the development site should leave with the same intensity as the undeveloped site.  A detention system will need to be constructed to hold storm water for the increased runoff which is a result of new roof and paved areas for a storm event having a 10-year intensity rainfall and a 100-year intensity rainfall.  In most cases, the study to determine the type and size of the storm water detention should be completed by a qualified engineer or architect.

Review of Plans: 
The City Engineer will review the storm water detention plan.  The review can usually be completed within 3 to 5 working days.

Permit Fee Schedule: 
No fee.
