Planning Commission Minutes - January 16, 2001 Page 2 Baker said it appears the size of the holding pond had been reduced. Wickman said the holding pond was modified to accommodate overland water flow and provide underground drainage storage. rd Leonard Crum, 833 23 Ave. NW, noted concern of the retention ponds on the north side and additional drainage problems. Wickman said the current plan eliminates the infiltration basin adjacent to the homes rd along 23 Ave. rd Baker noted a resident concern of drainage runoff traveling down 23 Ave. Wickman said this problem was addressed by the street reconstruction project which added a storm water drain pipe adjacent to the northerly east property line. Baker believes this problem presently remains. Crum said the majority of the problems rd had been resolved, but during time of heavy rains drainage travels down 23 Ave. Wickman said the main concern is that the project does not aggravate the problem. Bob Gephardt, 725 Silver Lk. Rd., said the view from his backyard will change from a baseball field to a parking lot, and believes the new parking configuration will create additional traffic congestion. Elaine Pelsman, ATS&R, explained that the reconfiguration will improve the circulation and aesthetics of the parking lot, and provide separation of the bus and vehicle traffic. Katie Gephardt, 725 Silver Lk. Rd., believes this arrangement will intensify difficulties accessing their driveway, decrease property values, and increase drainage collection in the ballfields. Pelsman said the proposal does not increase the number of parking stalls, but would improve current drainage problems. th Leonard Linton, Clark Engineering, explained that the current drainage system involves the 7 St. catch basins and open field drains. After consultation with the Rice Creek Watershed District (RCWD), the plans show a series of infiltration basins with storm sewer outlets which retain runoff up to 72 hours and an outlet pipe which directs drainage to an underground storage chamber. The underground storage chamber will have the equivalent of an above ground holding pond. This plan meets the requirements of the RCWD. O’Brien asked if the Gephardt’s sump pump runs year around. Gephardt confirmed that in unique circumstances the sump pump will operate. O’Brien added that the soil boring did not show a significantly high water table. Wickman reiterated that the project would not aggravate a situation, however, clay soils tend to prolong drainage. Gephardt asked if the City or School District have methods to determine ramifications of a project to adjacent residential properties. Zisla said the staff comments in the report state “that the special use will not be injurious to the use and enjoyment of other property in the immediate vicinity for the purposes already permitted, nor substantially diminish and impair property values within the neighborhood”. th Margaret Noyd, 2260 7 St., explained that continual improvements to the school property have created drainage in their backyard and fear additional problems with this current proposal. Wickman explained that one easy resolution to remediating the drainage problem would be to install additional fill in the backyard and replace landscaping. Zisla asked if a condition of approval could be added which refers to an easement relating to the remediation. Noyd acknowledged that an easement would be acceptable. Noyd asked if the proposal allows for entrance of emergency equipment. Community Development Director Kevin Locke noted that the Public Safety Department has reviewed the plans and are satisfied.
