Tyrrell Park Stream Stability & Water Quality Project
The City of Lincoln Public Works and Utilities Watershed Department and the City of Lincoln Parks and Recreation Department have completed improvements to Tyrrell Park. The project will improve stormwater quality, reduce stormwater flow velocities, reduce potential flooding threats to adjacent properties, and provide environmental education opportunities for Mickle Middle School and the general public. The project area includes the west side of Tyrrell Park, directly north of Mickle Middle School.
The design includes several features to improve stormwater quality. Stormwater management practices include a grass channel, infiltration basins that detain and infiltrate stormwater, permeable pavers in the north parking lot, pervious pavement in the south parking lot, and various native plantings. A device called a hydrodynamic separator has been installed, which will remove sediment and trash from street runoff before it flows into the park. The project also includes a new walking trail through the park with educational exhibits that feature native plantings, infiltration basins, examples of different regional stone, and educational signs.
