The City will concurrently with the adoption of the 2008-2030 CMP adopt an update of the SWMP. The 2009 Orono Local Surface Water Mana�ement Plan will be a separate document reviewed by Metropolitan Council and Minnehaha Creek Watershed District under the authority of Minnesota Statutes 103B.235. The maior policv chan�es from the 2002 Surface Water Mana�ement Plan relate to infiltration and water ualitv treatment for new development and redevelopment and to Orono's Phosphorus Reduction Plan (PRP). Thou�h Orono will not see si�nificant redevelopment the Cit�'s development/redevelopment goal is to seize every opportunitv to retrofit rate control, infiltration, and water qualitv treatment. While this �oal emphasizes takin� advanta�e of opportunities that present themselves. the City will also take s�ecific steps throu�h its own Capital Improvement Projects to obtain the phosphorus load reduction described within its PRP This phosphorus load reduction strate�y is mandated in Minnehaha Creek Watershed District. Orono must develop a plan to reduce phosphorus in its surface water dischar��30 pounds per vear over the 10- e�ar span covered bv the 2009 Local Surface Water Mana�ement Plan update. Consequentiv, the update focuses on potential proiects and development controls and guantifving actual load reductions from these activities. Projects that occurred since vear 2000 will be reviewed and any phosphorus reduction that �oes bevond what is otherwise required will be credited toward the 230 pound per year reduction. Orono's Local Surface Water Management Plan requires the use of functions and values assessments as a companion to the wetland delineations that ty ip cally accompany development applications. City-wide wetland inventories conducted by Orono and then the Minnehaha Creek Watershed District have determined function and values for wetlands throu�hout the City. Accordin� to its recent wetland ordinance and in conjunction with the watershed Orono stipulates buffer and treatment standards for wetlands based on these function and values. The Minnesota Pollution Control A ency has designated the Citv of Orono as an National Pollutant Discharge Elimination Svstem (NPDES) Phase II Municipal Separate Storm Sewer System (MS4) community. Orono's Stormwater Pollution Prevention Plan (SWPPP) is a permit requirement and addresses six minimum control measures: 1) Public education 2) Public involvement 3) Illicit discharge detection and elimination 4) Construction site runoff control City of Orono Community Management Plan 2008-2030 Page 3A-28
