Post -construction stormwater management <br />A. Do you have a regulatory mechanism(s) to address post -construction stormwater management activities? <br />® Yes ❑ No <br />1. If yes: <br />a. <br />Check which type of regulatory mechanism(s) your organization has (check all that apply): <br />® Ordinance ❑ Contract language <br />® Policy/Standards ❑ Permits <br />❑ Rules <br />❑ Other, explain: <br />b. Provide either a direct link to the mechanism selected above or attach it as an electronic document to this <br />form, or if your regulatory mechanism is either an Ordinance or a Rule, you may provide a citation: <br />Citation: <br />1) Regulatory mechanism is established in City Code, Section 803.04 and Chapter 1017, Section 1017.26. <br />2) Policies are established in the Comprehensive Surface Water Management Plan (Goals 1 and 2, Policies - <br />all). <br />3) Standards are established in a stand alone document titled "Storm Water Management Standards." <br />Direct link: <br />1) City Code can be found by accessing the following web links: <br />a) http://www.cityofroseville.com/index.aspx?NID=1703 <br />b) http://www.cityofroseville.com/index.aspx?NID=1727 <br />2) Policy is in the Comprehensive Surface Water Management Plan: <br />b) http://www.cityofroseville.com/DocumentCenter/Home/View/12712 <br />3. Storm Water Management Standards (attached pdf) <br />® Check here if attaching an electronic copy of your regulatory mechanism, with the following file naming <br />convention: MS4NameHere_PostCSWreg. <br />B. Answer yes or no belowto indicate whether you have a regulatory mechanism(s) in place that meets the following <br />requirements as described in the Permit (Part III.D.5.a.): <br />1. Site plan review: Requirements that owners and/or operators of construction activity submit ® Yes ❑ No <br />site plans with post -construction stormwater management BMPs to the permittee for review and <br />approval, prior to start of construction activity. <br />2. Conditions for post construction stormwater management: Requires the use of any <br />combination of BMPs, with highest preference given to Green Infrastructure techniques and <br />practices (e.g., infiltration, evapotranspiration, reuse/harvesting, conservation design, urban <br />forestry, green roofs, etc.), necessary to meet the following conditions on the site of a <br />construction activity to the Maximum Extent Practicable (MEP): <br />a. For new development projects — no net increase from pre -project conditions (on an annual <br />average basis) of: <br />1) Stormwater discharge volume, unless precluded by the stormwater management <br />limitations in the Permit (Part III.D.5.a(3)(a)). <br />2) Stormwater discharges of Total Suspended Solids (TSS). <br />3) Stormwater discharges of Total Phosphorus (TP). <br />b. For redevelopment projects — a net reduction from pre -project conditions (on an annual <br />average basis) of: <br />1) Stormwater discharge volume, unless precluded by the stormwater management <br />limitations in the Permit (Part III.D.5.a(3)(a)). <br />2) Stormwater discharges of TSS. <br />3) Stormwater discharges of TP. <br />3. Stormwater management limitations and exceptions: <br />a. Limitations <br />■�affc <br />❑ Yes ® No <br />1) Prohibit the use of infiltration techniques to achieve the conditions for post -construction ❑ Yes ® No <br />stormwater management in the Permit (Part III.D.5.a(2)) when the infiltration structural <br />stormwater BMP will receive discharges from, or be constructed in areas: <br />a) Where industrial facilities are not authorized to infiltrate industrial stormwater under <br />an NPDES/SDS Industrial Stormwater Permit issued by the MPCA. <br />www.pca.state.mn.us 651-296-6300 • 800-657-3864 TTY 651-282-5332 or 800-657-3864 • Available in alternative formats <br />wq-strm4-49a • 5131113 Page 5of 15 <br />
