Chapter 11 I Placemaking and Managing Development
11.218 Development proposals should integrate green and blue infrastructure measures to offset peak flood flows including the following options: 1. Nature-based solutions and “slow-the-flow” initiatives; 2. Incorporation of SUDS to limit runoff from existing and new development; 3. Wetland enhancement on flood plains; 4. Native tree planting and landscaping schemes; 5. Green roofs and green walls; 6. Rainwater harvesting and rainwater boxes; 7. Natural banks, water dykes and water squares; 8. Natural flood management techniques. Development Adjoining Watercourse Corridors 11.219 Development proposals in or adjoining watercourse corridors should: 1. Preserve the biodiversity value of the area subject to Ecological Assessment by a suitably qualified Ecologist; 2. Not involve landfilling, diverting, culverting or realignment of river and stream corridors; 3. Not have a negative effect on the distinctive character and appearance of the waterway corridor and the specific characteristics and landscape elements of the individual site and its context; 4. Protect and enhance wetland areas; 5. In new major development locations, preferably retain and protect existing riparian habitats while providing parks in waterside locations to maximise the potential linkages between landscape, natural heritage and recreational opportunity. 11.220 Development proposals should incorporate an appropriately-sized buffer zone to maintain natural fluvial processes and to protect the water environment. Greenways and blueways within the protection zone should be considered on a case-by- case basis, subject to appropriate safeguards and assessments.
Where appropriate, development proposals should enhance the green and blue infrastructure network by de-culverting, re-meandering or removing redundant structures or barriers to fish passage and enhancing bankside habitats.
11.221 Development proposals should protect
watercourses in accordance with Inland Fisheries Ireland’s “Planning for Watercourses in the Urban Area” including the protection of riparian sections of rivers and streams, where possible, as set out below. Existing development will be taken into account. 1. Protection of the streamside zone, (within 15m of riverbanks); 2. Utilisation of outer riparian buffer zone (>8m) for treatment and reduction of stormflow runoff; 3. Minimal disturbance of the corridor 15-30m from the river; 4. Explore opportunities for river corridors for access and use as local amenity; and 5. Encourage riparian buffer strips on agricultural land.
