Low Impact Development (LID)#
In February of 2013, City Council adopted the LID policy and criteria in Ordinance 152, 2012. This Ordinance was later updated in January 2016 with Ordinance 007, 2016 to provide additional flexibility in the implementation of the LID Policy.
The LID Implementation Manual has been adopted as part of the Stormwater Criteria Manual and is attached as Appendix C: LID Implementation Manual.
