Local authorities are critical partners of the Geological Heritage Programme of Geological Survey Ireland in protecting, through the planning system, those County Geoheritage Sites (CGSs) which fall within their county limits. In many cases, these are sites of high amenity or educational value, already zoned or listed in the plan. Inclusion in the County Development Plan (CDP) provides protection of the sites against potentially damaging developments that normally require planning permission, such as building, quarrying, landfilling or forestry. It is also important that the democratic process of public consultation and approval by councillors of the CDP allows stakeholders in the sites and the local community can buy into the process.
As the CGS is a non-statutory classification, but is covered by planning policies that protect and promote them, there are no specific restrictions on what a landowner can do with a geological heritage site. Any proposed development that requires planning permission simply flags the geological heritage interest of the site and allows it to be considered in any decision along with any other competing interests and values. It provides the opportunity for consultation and dialogue if any changes are proposed. It provides no protection from, for example, a farmer who wishes to clear a field of mushroom rocks, erratic boulders, or exposed geology for the purpose of replanting with grass other than, perhaps, an appreciation of what might be lost.
With the improved awareness by stakeholders of Geological Survey Ireland’s role as a statutory consultee (under its parent government department), the CGS route has been demonstrated to be working quite effectively as a means to protect and promote geological heritage. Most commonly, this is through consultation with quarry operators, resulting in their willingness to leave a representative rock face intact, and sometimes to further promote the geology at the end of a quarry’s life. In some cases, consultation has enabled the re-routing or re-positioning of components of national infrastructure to avoid potential impact on a CGS.
Positive outcomes from such engagement through the planning process have been relatively frequent, and some examples include:
- Tincone CGS, County Wexford.
- Nags Head Quarry CGS, Naul County Dublin.
- Trim Esker CGS, County Meath.
- Bruse Hill Quarry CGS and Blackwater Valley CGS, County Cavan.
The consideration of geological heritage in the planning system has been seen recently in projects that are key parts of government policy including the National Development Plan 2021-2030, Climate Action Plan 2021, the National Planning Framework 2040 and the Greater Dublin Area Transport Strategy 2016-2035 among others.
