Eagan council amends stormwater code to add post-construction infiltration requirements

The Eagan City Council approved an amendment to City Code section 4.34 on July 15 to add infiltration requirements for post-construction stormwater treatment systems.

City Attorney Ms. Miller told the council that Section 4.34 establishes regulations to manage stormwater runoff from land‑disturbing activities and that city staff identified updates needed to address changes requested by pollution control agency staff as part of the MS4 (municipal separate storm sewer system) permit process. Deputy Public Works Director Plath was present for questions, Ms. Miller said.

Council Member Fields moved to approve the amendment described as an update to Chapter 4, Section 4.34 addressing infiltration requirements for post‑construction stormwater treatment systems. The motion was seconded (second not named in the public record) and carried on a voice vote; the council chair called for ayes and, with no nays announced, declared the motion carried and the ordinance amended.

There were no public comments on the ordinance amendment during the meeting. The amendment was presented as a staff‑initiated update to keep city regulations consistent with permit obligations identified by state pollution control staff; council discussion beyond the motion was not recorded in the public transcript.

The council did not specify an effective date for the amendment during the public portion of the meeting and did not provide a roll‑call vote count in the transcript; the action was taken by voice vote.
