MINUTES OF THE <br /> ORONO PLAIVNING COMMISSION MEETING <br /> Monday,October 18,2010 <br /> 6:30 o'clock p.m. <br /> Section 4 provides a current assessment of surface water management in Orono,including storm water <br /> modeling,NPDES pernutting process,comparison of regulatory standards, and identification of issues <br /> and corrective actions. <br /> Section 5 describes in detail Orono's surface drainage system. <br /> Section 6 presents Orono's wetland management program and identifies wetland restoration and <br /> enhancement opportunities. <br /> Section 7 provides technical background for designing surface water management systems in Orono. <br /> Section 8lists the goals and policies identified to address surface water management systems in the City. <br /> Section 9 summarizes capital projects currently planned with lrnown funding sources to implement the <br /> goals and policies listed in Section 8,as well as potential activities and funding mechanisms,including <br /> the MCWD'S modeling program, Orono's MS4 permits, and an identification of potential issues and <br /> corrective actions. The capital improvement program plan items institute a series of proj ects over the <br /> next 10 years to reduce Orono's phosphorus discharge. <br /> Section 10 outlines the continued administration of this plan with respect to plan updates and <br /> amendments,as well as annual reporting requirements to Minnehaha Creek Watershed District. <br /> Gaffron state the most difficult issue to address is meeting the numerical phosphorus reduction goals <br /> established for Orono by MCWD. While the draft Phosphorus Reduction Plan meets or exceeds the goals <br /> for the Long Lake Creek and painters Creek subwatersheds,meeting the goals for the Lake Minnetonka <br /> Direct subwatershed is more difficult. This is due to most of that area being developed with relatively <br /> small lots and having short direct runoff patterns limiting the opportunities for projects that are cost- <br /> effective in terms of pounds of phosphorus reduced per dollar expended. Because both the Long Lake <br /> Creek and painters Creek subwatersheds ultimately drain to Lake Minnetonka,the Plan proposes that <br /> MCWD allow credit toward Lake Minnetonka Direct for any excess reductions proposed for these two <br /> subwatersheds. <br /> Winer asked if Norenberg Park had a phosphorus reducing program a few years ago. <br /> Gaffron indicated he does not recall a specific program for Norenberg. Gaffron noted there has been a <br /> number of phosphorus reducing projects undertaken by the MCWD over the past 20 years but that they <br /> have not achieved the level of reduction that they had originally hoped for. <br /> Additionally,while the MCWD currently administers the Wetland Conservation Act for Orono,proposed <br /> Water Resources Management Policy 8.Sa on Page 90 of the SWMP indicates Orono will,within the next <br /> 12 months, consider the option of assuming administration of WCA responsibilities to ensure no net loss <br /> of wetland functions and values. <br /> Curtis noted Staff had attended some training on buffer width requirements and things of that nature,it <br /> was clear that the City would need to completely change their code to match what the Watershed District <br /> is doing or meet or exceed the MCWD requirements to allow the City to take over that responsibility or <br /> oversight. <br /> Page 2 <br />
