Member Stenlund suggested such efforts for each pond in the City, since they were all part of the puzzle, with homes around those ponds being made aware of native vegetation, outfalls, and when failures are observed, they could alert staff, since part of Roseville's quality of life was its water resources. Member Stenlund suggested that the entire community could serve as storm water observers, not just staff Mr. Leaf advised that this Plan update was intended to move toward an"e-Plan," rather than a paper binder sitting on a shelf, making it more available to citizens. Mr. Leaf advised that the intent was to have the watershed map available on line and you could click on a particular pond and pull up other documents. Mr. Leaf suggested that some of the educational and outreach items mentioned by Member Stenlund could be incorporated into that effort, and available to commissions, residents and staff Ms. Bloom advised that S.E.H. was working on updating and enhancing the storm water section of the City's website as part of this process, making it the "go to" place for regulations, surface water plans, etc. to move its design from stagnant to more vibrant, informative and useful. At the request Chair Vanderwall regarding the status and future of the GIS web map, Ms. Bloom advised that she and Chair Vanderwall could discuss that further off line. Member DeBenedet observed, with respect to some problem flooding areas, that some areas of Roseville had developed prior to anyone being made aware of that nuisance. Member DeBenedet noted that this infrastructure design was based on a fairly low frequency of rain events; however, now flood protection for 100 year events were increasing with emergency overflow routes more well-documented. However, Member DeBenedet questioned if the City of Roseville, and/or its neighborhood residents had a good idea of those routes to ensure that they remained open for drainage during major rain events. Member DeBenedet suggested, as part of this Plan update, to identify those locations where high flooding had been experienced in the past, or where a potential existed. Member DeBenedet questioned the status of the U of MN Study commissioned by MnDOT subsequent to the 1987 "super storm," to review storm data and rainfall types and amounts for 100 year events. Ms. Bloom advised that the updated "TP 40" will be released soon, and spoke in support of Member DeBenedet's suggestion for identify overflow areas. Member DeBenedet further suggested a requirement for new developments, based on water quality design philosophies that those areas retain and continue to mimic natural runoff and stream flows. While recognizing that there were few areas in Roseville yet to be developed, Member DeBenedet suggested that this could be pursued when redevelopment occurs, and should be made key along with WSD Page 9 of 19
