In 1997, the RSWMP was established in an effort to protect public health and safety by requiring development to mitigate increases in storm water runoff resulting from their development. The program allows three options in which developers may participate to assist in this mitigation. The options include construction of onsite detention facilities, participation in the construction of a mitigation project, or paying a fee in-lieu-of (FILO). Effective April 1, 2013, a new methodology for calculating the FILO fees based on land use and amount of impervious cover was approved and adopted by City Council per Ordinance 2013-01-31-0074.

The Storm Water Plan Review team reviews storm water development plans to ensure future construction projects do not adversely impact current drainage systems. The links below provide information on the new Regional Storm Water Management Participation Form with the various categories and fees to reflect the new FILO process, a Frequently Asked Questions (FAQ) document in an effort to address and clarify the program, flowcharts to guide the customer on the process and payment of the FILO fees and the Ordinance approving the new FILO fees.
