WS – Item _3 WORK SESSION STAFF REPORT Work Session Item No. 3 Date: December 5, 2022 To: City Council From: Michael Grochala, Community Development Director Re: Draft Stormwater and Erosion and Sediment Control Ordinance Amendment Background City Code section 1011 regulates development activities that disturbs land and generates the need for storm water management. The City is required to adopt ordinance consistent with the requirements of the State’s General Permit to operate a municipal separate storm sewer system (MS4). The City was issued a new permit in October of 2021. Additionally, the City is required to be in conformance with the rules and requirements of the local water management organizations (WMO’s) – the Rice Creek Watershed District (RCWD) and Vadnais Lakes Water Management Organization. The proposed ordinance amendment is to bring our code requirements into conformance with the permit and WMO’S standards and simplify administration of the code. The RCWD covers the majority of the city with VLAWMO jurisdiction limited to a few hundred acres in the southeast portion of the City. For purpose of applying requirements uniformly the ordinance adopts the stormwater management requirements of the RCWD. New language is shown as underlined text and deleted text is shown with a strikethrough. ANALYSIS Sections 1011.001 through 1011.005: These sections were modified to remove superfluous language and recognize the adoption of certain code amendments by reference to RCWD or VLAWMO rules Section 1011.006 Definitions: The definition section was amended to update definitions for consistency with WMO’s and the MS4 permit, and delete unnecessary terminology. Section 1011.007 through 1011.009: These sections were modified to remove superfluous language and correct references.
