Rivers, Streams and Canals are key features in many Millennium Greens. A number of Greens either have one on one edge or flowing through the Green.
Safety[]
As with all water features, Greens need to consider risk factors and such things as barriers and railings on bridges.
Stability[]
The flow of water is always liable to wear the banks away and cause collapse. Greens need to survey and plan for maintenance of the banks.
