The Village of Tinley Park is in the early stages of developing Legacy Pond, a naturalized detention basin to be located on eight acres of the Panduit property at the northeast corner of 175th Street and Ridgeland Avenue. Work will be performed by Dyer Construction and will begin early spring 2017.
The purpose of the Legacy Pond is to provide for the storm water needs of the downtown Legacy District redevelopment. Redevelopment creates new impervious surfaces which can increase the volume of storm water water run-off. The run-off is controlled through a system of storm sewers and detention areas to prevent downstream flooding impacts. This pond will serve redevelopment projects in Downtown Tinley, including the former Central Middle School property and sites on North and South Streets.
Naturalized detention basins have more functional value for the community because they help with water quality. They also provide a reduced initial cost, less land requirements, cheaper long-term maintenance, and are more aesthetic, with wildflowers and the birds that it will attract.
The benefits of a centralized pond to handle the main street district include:
- Elimination of small, postage-size detention ponds that are land-intensive, costly and inefficient.
- More developable land in the higher-density section of Oak Park Avenue, thus improved land value.
- Volume control requirements are provided through the Legacy Pond. Costly impacts to the Main Street district are avoided and there is no reduction in usable land.
- Development through the aggregation of land is not penalized.
Project Schedule (Weather Dependent)
Week of 5/1/2017
– Began removals (trees, light poles, water main work) on pond property and begin earth excavation for the pond
Week of 5/8/2017
– Continue earth excavation for the pond
Earth excavation of pond is estimated to take 2-3 months due to the amount of dirt needing to be hauled off
Storm sewer work is tentatively scheduled to begin after school gets out for the summer as to minimize impacts to traffic
Project completion for all work associated with the excavation and grading of the pond, removal and installation of storm sewer, pavement and landscaping restoration and all natural area landscaping for the first growing season is set for November 30, 2017. All other natural area landscaping areas are set for June 30, 2018 as some of the grasses and plantings are Spring installation only
