Urban parks can cut the cost of managing stormwater by acting as mini reservoirs, according to a review of Cardiff’s parkland.
A task-and-finish group this week urged the council’s executive to put an economic value on parks’ wide-ranging benefits, which include reducing carbon footprint and air pollution, and improving public health. The group said funding opportunities had not always been fully exploited for Cardiff’s parks.
‘Parkland reduces stormwater management costs through capturing precipitation and/or slowing its runoff,’ says the group’s report.
Runoff from roads and other hard surfaces can carry pollutants into watercourses and some is treated at pollution control facilities, says the report. Cardiff’s parks and green spaces represent 28.5% of Cardiff’s fluvial floodplain and 7.8% of its tidal floodplain.
