Tramore Local Area Plan - Waterford County Council

Chapter 11: Development Control StandardsSurface water runoffWhere deemed necessary, the Planning Authority may require the provision ofappropriate measures for the interception of pollutants from surface run-offassociated with hard standing areas such as fuel storage areas, car parking areasand roads to prevent the entry of same into surface waters. The construction andsubsequent operation of developments within the Local Area Plan area shouldnot result in discharge of polluting materials to surface and/or groundwaterresources.Flood Risk and DevelopmentAppropriately designed developments, which are not sensitive to the effects offlooding, may be permissible in flood plains provided it does not reduce theflood plain area or otherwise restrict flow across floodplains.Development must so far as is reasonably practicable incorporate the maximumprovision to reduce the rate and quantity of runoff. eg:- Hard surface areas (car parks etc), should be constructed in permeable orsemi-permeable materials;- On site storm-water ponds to store and/ or attenuate additional runoff fromthe development should be provided;- Soakaways or French drains should be provided to increase infiltration andminimise additional runoff.For developments adjacent to watercourses of a significant conveyance capacity,any structures (including hard landscaping) must be set back 5m – 10m from theedge of the watercourse to allow access for channel clearing/ maintenance.All new development must be designed and constructed to meet the followingminimum flood design standards:- for urban areas or where developments (existing, proposed or anticipated)are involved – the 100 year flood;- along the Coast and Estuaries – the 200 year tide level;- where streams, open drains or other watercourses are being culverted – theminimum permissible culvert diameter is 900mm (access for maintenanceshould be provided as appropriate).A flood impact assessment and proposals for the storage or attenuation of runoffdischarges (including foul drains) to ensure the development does notincrease the flood risk in the relevant catchment, must accompany applicationsfor planning permission for the development of areas exceeding 1Ha.11.9.3 Waste ManagementThe Council will encourage the reuse of waste and excavated materialsgenerated during the construction phases of development within the site. Anysurplus excavated/constructional/demolition material to be removed from thesite shall be brought to an authorised facility, following the authorisation of the86
