were recently completed in 2012 to restore the Villa Park Wetlanby removing accumulated sediment and the project is scheduled to be completed in 2013. 5.1.8Gottfrieds Pit Pump The City of Roseville cooperated on a study of downstream flooding and water quality issues with CRWD, Falcon Heights, the City of St. Paul, and Ramsey County in 200 northwestern watershed area to Como Lake. Roseville drains 315 acres to this system. Just east of Gottfried's Pitis a low point in local topography near the intersection of Larpenteu Avenue and Fernwood Avenue which is prone to frequent flooding. Solutions to mitigate the flooding issue on Larpenteur involved increasing the volume storGottfried's Pit countered by a pump upgrade for a faster draw-down time and closing the valve located in the pipe connecting the Ramsey County storm sewer trunk to the lift station. 5.2Ongoing Issues While the previous section provided just a few of the many proje accomplishments the City has made in the 20 plus years since com water management plan, there is also more work ahead. Many of the flooding issues of the past have been addressed, but some remain. New water quality issues and concerns are emerging each year, requiring varying levels of effort by the ci ongoing maintenance and operation of the storm water system has complex over the years due to new regulations and a better understanding of what is necessary to keep the treatment ponds and filtration systems fun An example of one of these complex issues is the management of contaminated st sediment dredged from stormwater ponds. This section of the plan provides an overview of some of the more significant of these ongoing issues that will r resource commitments. Location specific issues such as localized flooding issues and ongoing impairments are identified in Figure 19. 5.2.1Localized Flooding Issues While many of the known flooding areas have been addressed by in improvements over the past 20 years, some remain and are identified in the impleme section of the plan. Unfortunately, the very nature of storm wa some point new issues will likely present themselves due to the from debris, for example, or simply a larger or more intense rai previously experienced. The flooding in Duluth, Minnesota in June 2012 is a notable example of how a storm larger than anticipated can create problems wherewere anticipated in the past and will require extensive repair and restoration work Specific known local flooding issues are presented below in Table 14.
