An ICW was developed in 1999 by Dublin City Council with in the Fingalswood Stream in Tolka Valley Park. The ICW located alongside the Tolka River has provided flood attenuation, amenity, increased biodiversity and habitat value.

Dublin City Council commissioned a biodiversity survey of the ICW in June 2008 which concluded that “The establishment of the ICW at Tolka Valley Park is an excellent example of how… biodiversity can be harnessed for the benefit of people in this case transforming a foetid quagmire (neglected stream) into a water purification unit with amenity value”.

The incidents of social misbehaviour has also noticeably decreased in the site since the development of the ICW.
