The DNR technical standard 1002, Site Evaluation for Infiltration, has been updated by a Standards Oversight Council Full Process team. This team of 9 experts drafted new criteria over the course of a year, including input from outside experts and a public review period. The technical standard revises the procedures, updates the submittal requirements, and clarifies methods that can be used to design infiltration systems in compliance with NR 151, WIs. Adm. Code.

The revised technical standard is available at the DNR’s storm water post-construction technical standards webpage
