THE Launceston City Council will urgently assess its stormwater system and retention basins following recent floods in the suburbs.
The review follows the State Emergency Service's judgment over the weekend that stormwater drains around the city were unable to cope with last week's heavy downpour.
Northern State Emergency Service regional manager Mhairi Revie said the service had delivered sandbags to at least 250 homes in Kings Meadows, Summerhill, Riverside, Newstead and Newnham since the rain hit last week.
The council also received about 100 call-outs due to flooding between Wednesday and Sunday.
Council general manager Robert Dobrzynski said the council would map where the water had come from and urgently review the performance of its stormwater infrastructure and retention basins.
``The bottom line is that this cannot continue to happen and the council is committed to ensuring infrastructure is in place on both public and private land to manage storms of this nature,'' he said.
Mr Dobrzynski said the council would investigate drainage on private commercial properties at Kings Meadows as not all flooding could be linked to urban stormwater infrastructure.
``It is clear that the council needs to ensure its stormwater infrastructure can simultaneously prevent stormwater from reaching Kings Meadows from surrounding areas by infrastructure such as the Mount Pleasant Dam, the Connector Park Dam and perhaps augmented and additional retention facilities, while also ensuring that on-road stormwater infrastructure and infrastructure supporting the Kings Meadows rivulet has the capacity to deal with stormwater,'' he said.
``Kings Meadows sits at the bottom of a natural basin so it is prone to inundation, but we will be closely examining infrastructure designs to remedy this.
``In the short-term, we want to understand what is happening, and then we will review our overall strategies for the catchment and the Kings Meadows shopping area.''
