Middlegrounds Metropark Models Stormwater and Transportation Projects

Middlegrounds Metropark, the newest park in the Metroparks of the Toledo Area system, was opened to the public Saturday, September 17. The park is beneath the High Level Bridge and adjacent to the TMACOG offices and Amtrak/Greyhound station in the Dr. Martin Luther King, Jr. Plaza. It is the park system’s first in a totally urbanized area and demonstrates innovative stormwater management systems. Walking/biking paths in the park were funded through the federal Transportation Alternatives Program which was budgeted through the TMACOG Transportation Improvement Program (the TIP).

Torrential rain on the morning of the grand opening demonstrated how new stormwater maintenance structures in the park work. Rain that falls on High Level Bridge is now collected, drained to filter structures that collect debris, and directed to a created waterway. From there, stormwater moves through three detention ponds that are at decreasing elevations. The ponds allow water to slowly percolate into engineered soil where pollutants are naturally treated. The water that reaches the Maumee River is significantly cleaner than the water that rolls off the bridge above.

Stormwater is moving between ponds after a heavy rainfall.
Systems at the Middlegrounds park treat stormwater and prevent erosion.


A path makes it easy to carry down and launch kayaks and canoes from
the new park. This pond has an outlet to the Maumee River. The supports
for the High Level Bridge are on the top right of the photo.

Stormwater from the bridge is directed to this constructed waterway.
