City staff presented a major reorganization and technical update to the stormwater management manual and asked the council to authorize the city manager to approve the revisions under municipal code. Miss Johnson, the presenting stormwater staffer, said the manual has been reorganized for usability, outreach to engineers and developers was conducted, and technical changes reflect recent climate data and DEQ permit expectations.

Key technical updates Johnson highlighted include updated precipitation depths using recent station data (adjusting design precipitation from older NOAA baselines), relaxation in some on‑site flow criteria to improve implementability, a new requirement that large projects (treating 10,000 sq ft of impervious surface or more) provide a technical downstream analysis demonstrating they will not overwhelm adjacent property or the public storm system, and new source control requirements (for example, covered materials storage) to reduce pollutant loads. Johnson said these changes aim to reduce sediment and phosphorus discharge into Oswego Lake and to respond to more intense storm patterns.

Councilwoman (name not specified) moved to authorize the city manager to approve the recommended revisions as allowed by municipal code LLC 35‑25‑1102; the motion was seconded by Councilor Raff and passed on a roll‑call vote, recorded as 7–0. Staff will notify engineering and developer stakeholders, post implementation materials on the project web page, and provide internal staff training as the manual is implemented.
