In 1987 the Illinois Department of Transportation contracted the Northeastern Illinois Planning Commission (NIPC) to perform a study to determine the effectiveness of the current accepted detention practices and to investigate the detention needs of the six county Chicagoland region. The NIPC study 'Evaluation of Stormwater Detention Effectiveness in Northeastern Illinois,' June 1989, determined that many current detention practices were indeed inadequate for northeastern Illinois, and that there was a need to improve and expand detention policies. This paper provides a summary of the detention effectiveness evaluation and discusses the effort in Illinois to implement more effective stormwater management practices using tools, such as a model stormwater detention ordinance developed from the NIPC study.
