Pleasant Hill Park Stormwater Retrofit

The City of Lindstrom has identified the subwatershed that includes Pleasant Hill Park as a high priority for a stormwater management project due to the high volume of untreated stormwater discharging directly into South Lindstrom Lake. This is a cooperative project between the City of Lindstrom and the Chisago Lakes Lake Improvement District.
This 66 acre catchment receives runoff water from residential, commercial downtown and light industrial areas. The park is used as a playground in summer and an ice skating rink in winter. The storm sewer is not sized to handle runoff from wider streets and more impervious surfaces and the outlet in South Lindstrom Lake is under water. During high rain events sediment is carried into the lake and creates a large delta three to four feet below the surface of the water, which also creates a hazard at the private beach area where the outlet is located. Due to the lack of upstream treatment, debris (cigarette butts, papers, cups) is carried directly into the lake and deposited on the shoreline. Filtration and holding areas upstream of the lake will resolve these issues. Adding locations to infiltrate water in the watershed will increase the effectiveness of the current stormwater infrastructure.
