APPENDIX 23 Development of the EPR following public consultation

Guide to the “Comparative Assessment of Alternatives”

The following matrices summarise the comparative assessment of the alternative route alignments with respect to the existing route from the Draft Route Selection Report. A ranking system has been used to indicate the degree of preference given to the various alignments being compared as follows:-

Highest Preference

Least Preference

No specific preference for any alignment being compared

Secondary Preference*

* = Where more than two alignments are being compared

See Drawing Alt 10

RSR Chapter		Existing Route	Alternative Route	Comments
4	Landscape and aesthetics			- Alternative could potentially have a greater visual impact due to prominent cutting through rock outcrop on Athsollis Bridge road - However, the overbridge on Athsollis Bridge road may constructed at grade (or close to at grade) and having a lesser visual impact

6	Surface water quality and drainage			- The alternative alignment will have a marginally greater adverse effect due to it being closer to the river
7	Geology			- The alternative results in a marginally worse impact on geology due to the deep cutting through the rock outcrop on Athsollis Bridge road
7	Hydrogeology			- The alternative alignment could have a marginal improvement on hydrogeology because it is located further away from a major spring
8	Ecology			- There is potentially a marginal improvement due to less severance of ecological area 52a

7	Geology				- Large embankment required for northern route
7	Hydrogeology				- Nil or marginal difference

5	Cultural heritage			- Alternative would have a slight increase in impact on Cultural Heritage
6	Surface water quality and drainage			- The alternative route is located slightly further from River Bride and tributary. The crossing of the tributary would be close to existing N22 crossing point, which would result in slightly less impact on an untouched section of the tributary
7	Geology			- Marginal or nil
7	Hydrogeology			- Nil
8	Ecology			- Alternative route would have less impact on area 55d
9	Air quality			- Marginal or nil

See Drawing Alt 14

RSR Chapter		Existing Route	Alternative Route	Comments
4	Landscape and aesthetics			- Greater length of the Alternative route would be visible in green field land/ adjacent to river
5	Cultural heritage			- Minor differences in impact on some built heritage sites - Overall nil or marginal difference
6	Surface water quality and drainage			- Alternative is in very close proximity to river, which increases potential for pollution during construction and long term from road spills - There is also greater impact on flooding risk

7	Hydrogeology			- Marginal or nil
8	Ecology			- Alternative would have greater impact on ecological value of River Bride (important fishery and potential candidate SAC)
9	Air quality			- The alternative route is located further away from dwellings located along existing N22
10	Noise and vibration			- The alternative route is located further away from dwellings located along existing N22
11	Planning			- Nil
12	Socio-economics			- Nil
13	Demolition and loss of amenity			-Nil

15	Mineral Resources			- Nil
17	Construction Impacts			- Alternative would have major increase impact associated with construction adjacent to river
16	Road Alignment			- Nil
18	Cost Estimate			- Reduction in cost expected due to number of farm access underpasses deleted by alternative - This would be offset by an increased cost of higher embankments, enhanced drainage requirements, more difficult construction and flood mitigation requirements for the alternative route

See Drawing Alt 16

RSR Chapter		Existing Route	Alternative Route	Comments
4	Landscape and aesthetics			- The alternative would result in greater visual impact on views from Kilcrea Friary - The alternative would require a raised structure on the Boreen road, which will also increase visual impact - However, alternative will significantly reduce the visual impact on dwellings located in the northern part of the Abbey Road settlement - Overall existing route has lower degree of landscape and visual impact
5	Cultural heritage			- The alternative is significantly closer to Kilcrea Friary and other known monuments in the area (NIS119, NIS120, AH191, AH121 and Kilcrea Castle)
6	Surface water quality and drainage			- Close proximity of alternative to river (as well as the requirement to straighten a section of the river) increases potential for pollution during construction and long term from road spills

7	Hydrogeology			- Alternative route requires deeper cuttings
8	Ecology			- Alternative would have greater impact on ecological value of River Bride (important fishery and potential candidate SAC)

13	Demolition and loss of amenity			- Marginal or nil
14	Agriculture			- Marginal or nil
15	Mineral Resources			- The alternative route would improve the impact on mineral resources - The major benefit resulting from the alternative is that it addresses the concerns regarding access to lands available in the short term for continuation mineral extraction activities
17	Construction Impacts			- Alternative requires a skewed crossing of the Boreen road - Alternative runs close to the River Bride requiring localized realignment of the river
16	Road Alignment			- The alternative appears to provide minor improvements to the road alignment
18	Cost Estimate			- Increased costs associated with additional road crossing and proximity to river are likely

A23.1.18 Alternative 17 – Comparison of Yellow Route, Yellow/Link6/Blue Route and Yellow/New Link/Blue Route (“the alternative”)
– Kilcrea/Garryhesty/Knockanemore/Carrigane
– Station Road to Ovens – Ch43+500 to Ch38+750

See Drawing Alt 17

RSR Chapter		Existing Route (Yellow)	Alternative Route (Yellow/Link6/Blue)	Alternative Route (Yellow/ New Link /Blue)	Comments
4	Landscape and aesthetics				- Yellow/New Link/Blue would have lowest visual impact (fewest receptors) - Yellow and Blue / Link 6 Route Options traverse land of similar or equal landscape character
5	Cultural heritage				- Greatest impact due to proximity of Yellow/New Link/Blue to Kilcrea Friary
6	Surface water quality and drainage				- Yellow/New Link/Blue least preferred due to this alternative being closest (on more occasions) to the River Bride
7	Geology				- All have similar impact
7	Hydrogeology				- All have similar impact
8	Ecology				- Yellow/New Link/Blue is least preferred due to this alternative being closest (on more occasions) to the River Bride - River Bride is considered potential candidate SAC
9	Air quality				- Yellow Route is closest to the maximum number of potential receptors
10	Noise and vibration				- Yellow Route is closest to the maximum number of potential receptors
11	Planning				- All routes impact on significant areas identified in the Development Plan - The Blue/NewLink route has the greatest impact on environmental planning policies - The Blue/Link6 route impacts on both the mineral resource and environmental planning policies - Both the Blue/Link routes have the greatest effect on the “development area” situated north of Killumney - Yellow route has the greatest impact on mineral resource planning policies
12	Socio-economics				- Existing route is least preferred due to this routes potential to have the greatest adverse economic and employment impact (mineral reserves)
13	Demolition and loss of amenity				- All have similar impact
14	Agriculture				- All have similar impact
15	Mineral Resources				- The Yellow Route will sterilize the greatest volume of the better deeper mineral reserves in the Bride Valley
17	Construction Impacts				- The existing route would present the least impact mainly due to this route being the furthest from the River Bride
16	Road Alignment				- All have similar impact
18	Cost Estimate				- The Yellow route will require the acquisition of more land through the area of greatest value mineral deposits
