MOTION NO.3
MOTION: Councillor L. O’Toole
This committee requests that CE provides a detailed report regarding cleansing protocol of culverts along the Griffeen park and shores along the streets of Lucan village. How often are these cleansed & cleared of debris. With the high volume of rain lately the shores in Lucan village are regularly cleared out by local businesspeople. The committee seeks to have commitment from council that the necessary additional clearing of shores in the village are carried out by the council.
REPORT:
The road gullies in Lucan Village are cleaned on a scheduled basis by the contractor who provides the road sweeping service across the county, Oxigen Environmental Ltd. The service is provided on a yearly basis to the majority of the 45,000 road gullies in the county, with a percentage of these serviced twice or four times yearly as required. The gullies in Lucan Village are on the increased frequency of service with those gullies in the Village Green area and those on the main street between Village Green and the Liffey Bridge serviced four times per year. Gullies in all other locations in Lucan Village are serviced twice per year. The service provided includes the cleaning and testing of all gullies, where a gulley is cleaned but found not to be functioning the pipe connecting the gulley to the main drain is cleaned by the contractor and the gulley is then re-tested. If it is still not functioning the matter is referred to the Roads Dept to examine the condition of the main drain. As well as cleaning of gulley chambers it should be noted that the street cleaning and road sweeping which is carried out by both Public Realm staff and the road sweeping contractor should ensure that there is no build up of debris on the surface of the gulley which would interfere with it’s proper functioning. The leaf sweeping and removal service which is also provided by the road sweeping contractor and which operates during the period September 1st to January 31st also involves the removal of leaves from gullies in the village when requested.

The surface water channels in Griffeen Valley Park are monitored and inspected on a continuous basis with action taken as required to remove potential blockages to those channels. Particular attention is paid to any culverted crossings underneath paths and roads as these are most likely to become blocked. In advance of any forecasted storms or heavy rain these locations are inspected and potential blockages removed. It should be noted that certain locations within our public parks have been identified as attenuation areas and flooding will occur at such locations in certain circumstances, in order to prevent flooding at other more sensitive locations such as residential developments.
