Project summary

Edit project overview to modify the project summary.

The Isar Plan Project is a river restoration project on a stretch of 8Km in the inner city of Munich. The Project was initiated in 2000 and the last site was completed by 2011. The three main goals of the project were: 1) Flood protection 2) Enhancing Species diversity and ecological restoration 3) Improving leisure and recreation

The project is being currently monitored.
