The Water Park is required to provide essential water attenuation and flood alleviation as well as providing ecological, recreation, amenity and circulation functions. Three large attenuation ponds dominate the park with fluctuating water tables and permanent water expected to be present throughout the year. Graded pond edges are shaped to create opportunities for access and recreation as well as providing a rich ecological environment of wetland, riparian and aquatic vegetation.
