Minutes of N22 Ballyvourney – Macroom – Ballincollig Road Project

 

Introduction: JD provided a brief introduction outlining the purpose and objectives of the workshop, and the Programme Key Milestones.

 

Key Constraints: Five minutes was allocated to each person to describe the key Constraints relevant to their particular input into the Project to date.

 

Ecology (MP): There are six designated sites (Primary Constraints) located within the Study Area which should be avoided if at all possible. These are: The Gearagh (SPA etc), St Gobnet’s Wood (pSAC, pNHA), Prohus Wood (pNHA), Boylegrove (pNHA), Gough Gal (pNHA) and Glashagarriff River (pNHA). There is also a “Bat” Site at Dunisky. There are also a number of “other” sites which are considered valuable in terms of ecology.

 

Further comments:

Habitats towards the western end of the Study Area (SA) are considered more important than those at the eastern end.

All Rivers within the SA are considered to be ecologically sensitive also.

The Bride River, Lee River and the “Bat” Site are potential SAC sites?

The NHA’s are considered to be of lesser importance than SAC sites, however they are all very important (Dúchas).

In terms of Ecology, the Route Options towards the western end of the SA should pass to the north of Ballyvourney.

 

Archaeology (JG): There are five sites (Monuments) in Ownership or Guardianship of the Minister (Primary Constraints): Graveyard of the Franciscan Abbey at Kilcrea, Lissacresig Ring fort and Stone Circle, Carrigaphooca Castle and Carrigaphooca Multiple Stone Circle. There are also an additional 844 archaeological sites which are scattered across the SA.

Possible need for an Archaeological Survey during the SI for the Preferred Route.

 

Agriculture (NM): In terms of Agriculture, the most productive land is located to the east of the SA, east of Macroom.  In general, the farms east of Macroom are larger and more productive. Conversely, the farms to the west of Macroom are smaller and less productive.

It appears that Scenic Importance Areas, Scientific Importance Areas, Scenic Routes and Views fall under the protection of the Local Planning Authority, and are not Nationally protected. In these areas development “must not dominate the landscape” (CCC Development Plan).

 

Land Use / Services (WJ): The land use within the SA is mainly agricultural. There are also a number of quarries, and there is one current Mineral Exploration Licence for an area near a quarry at Ovens.

The main services in the SA comprise: ESB High Voltage Power Lines, the two dams and hydro power facility, Group Water Schemes and Sewerage Schemes with associated reservoirs and treatment works (Ballyvourney / Ballymakerra and Macroom), RTE transmission towers, and Optic Fibre (likely along N22 and proposed at Ovens) .

The two dam structures and the quarries (possibly) would be considered as Primary Constraints.

 

Geology (JB): There are two basic rock formations: Sandstones/Mudstones and Limestones. The overburden soils are likely to comprise sands and gravels, which is consistent with the number of existing sand and gravel quarries located within the SA. The small number of soft soil / alluvial deposits located within the SA are not likely to be very thick.

There are no real geological constraints, however the route options should avoid areas of flooding.

The major constraint will be Topography.

 

Hydrogeology (JS): The limestone formation located within the SA are described as having “Karst. Good Development Potential” and “Fissure Flow”. Two Karst features have been also identified within the SA.  The main constraint in terms of new road construction is to ensure that NO road run-off flows into “Productive” aquifers.

Also, in terms of defining routes, we should keep away from Group Schemes. Also, if the proposed road “misses” a house, then it is likely that the extraction point for a domestic groundwater well will also be missed.

 

Hydrology (JS): Hydrology comprises all surface waterways / watercourses (i.e. reservoirs, rivers and flooding areas). Water quality throughout the SA appears to be very good at the moment. The flooding areas can be engineered over.

The Ballincollig Bypass design incorporated shallow embankments over Karst areas, rather than cuts, in order not to disturb the groundwater equilibrium.

 

Engineering (ML): The main constraints in terms of engineering are: Topography, the River Valleys / Crossings (Rivers Sullane, Bride and Lee), and the mountainous areas throughout the SA, and more importantly, west of Macroom.

The start point of the project links onto the Ballincollig Bypass, and will be Dual Carriageway. The end point will join onto the existing N22 west of Ballyvourney, and will be Single Carriageway.  The change from Dual Carriageway to Single Carriageway will most likely occur at the Macroom interchange.

 

Traffic (SC): The link roads from the proposed new route to Macroom should be kept as short and as safe as possible, to attract as much traffic as possible. This helps the Cost – Benefit Analysis.

Currently is approximately 10,000-15,000 AADT at Ballincollig, and 5,000 AADT at Ballyvourney, so traffic surveys will be carried out in the near future to determine the traffic movements throughout the SA. Approximately 10,000 AADT are lost in the Macroom area somewhere.

Consideration of the proposed locations of interchanges also needs to looked into.  Possibly depends on results of Traffic Analysis / Model.

 

PC 1 (JD/ML): JD provided a brief explanation of the ranking system used in the PC1 Database Summary. The results indicated that 92% of respondents believed that the existing N22 had to be improved.  The main issues that the respondents believed that the Proposed new N22 road should improve road safety, improve traffic conditions and should not impact too much on people living near the new route.

 

Route Options Discussions: MC / SC presented a large map of the SA showing Four Route Options (Blue, Yellow, Red & Green).  A Purple Route was also shown to the west of Macroom, linking with either the Yellow or Red Route. The following table summarises the different aspects of each route.

Pros of Route

Low number of houses affected.

Large part of route on-line. Passes close to Macroom.

Shortest route. Passes close to Macroom.

Second shortest route. Passes close to Macroom

Cons of Route

Passes close to The Gearagh, and the Bat Site.

Need a long link road into Macroom (possibly have to upgrade existing N22 into Macroom).

Large amount of properties affected.

Passes close to Burial Sites west of Macroom

Ovens Caves affected?

LUNCH

 

Route Options Discussion: The Key Decisions made were as follows:

 

The Southern Bypass of Macroom shown on the Yellow Route was discarded due to its proximity to the SAC, topography problems, the large industrial site on the N22, and difficulties in creating an interchange near Macroom.

The Purple Route west of Macroom was discarded due to the fact that the other routes (Blue, Yellow, Red and Green) are performing the same operation, but are shorter in length.  This route required two crossing of the Sullane River and crossed hilly terrain.

The Ballincollig Bypass start point of this scheme needs to be reviewed in detail in engineering terms.

All Routes plotted today (approximately 10-12) would be assessed in a “Broad Brush” format to attempt to remove a few prior to carrying out the detailed Route Assessments.

SC to talk to CCC (TC) about obtaining DTM Files from the OS to produce VA/HA for the route options.

 

Programme:

 

MC/SC require the Orthophotos of the Area ASAP. WJ to obtain cost and time estimates ASAP.

SC to draw up long sections of all routes, including text identifying route colour, node numbers etc. ASAP in order for other personnel to carry out “Broad Brush” assessments.

Parameters for the “Broad Brush” assessment include:

Total Route Length and Route Length from Ovens to Macroom;

Topography assessment (i.e. cuts and fills);

Access to Macroom (i.e. link road lengths and interchanges);

Approximate Cost (related to length of dual carriageway and single carriageway, earthworks, and major river / reservoir crossings)

Environment (Ecology, Archaeology, Hydrogeology/Hydrology)

Route Selection Workshop

1.       Introductions.  All present from McCarthy Hyder Consultants Ltd.

2.       JD ran though the route selection process and the tables to be used.  Assessment of route to be undertaken by comparing route between nodes 1 to 3, 3 to 6 and 6 to 16.

3.       JD outlined that there had been minor amendments to the routes since Public Consultation No.2. these revisions had been made to avoid properties and the gravel deposits to the south of the existing N22.

4.       The implications of the routes for the various disciplines were then discussed- see following sections.

5.       The various sections were discussed with regard to making amendments to avoid/mitigate constraints.  No other options were identified but minor amendments to be made on current alignments.

6.       In order to progress the scheme while awaiting results of the traffic study (see notes below) the following assumptions were made:

·        Dual carriageway assumed from R584 to Ballincollig tie-in. 

·        Termination of dual carriageway section to be roundabout junction

·        Junctions to be located at regional roads for dual carriageway section

Traffic and Economics

Steve Crudge outlined the current status of the traffic and economics work:

JD stated that the greatest priority was to obtain reliable model forecasts of traffic particularly for the Macroom - Ballincollig section for which the issue of the extent of dual carriageway needs to be resolved promptly.  A decision on carriageway standard is required to enable a full comparison of alternative routes to be carried out.

·        Assuming that the scheme comprises dual carriageway between Macroom and Ballincollig and single carriageway between Ballyvourney and Macroom, the  change in standards should take place at a logical location i.e. at one of the junctions accessing Macroom.

·        Junction location and type: this will be confirmed by the traffic model but a preliminary assessment can be made.

·        Traffic figures are required for the Ballincollig Bypass from Cork CC.  Action JD.

 

Ecology:

Annex Habitat. It is understood that Dúchas do not intend to designate any new Special Areas of Conservation (SACs).  However, any areas/sites that contain habitat listed in Annex 1 of the Habitats Directive and which therefore could be designated as an SAC are to be treated by Dúchas as though they were designated, and should therefore be avoided. Following initial surveys, the areas listed below, along the various route corridors,  have been identified as areas that may contain Annex 1 type habitat.

More detailed surveys are currently underway which should confirm whether or not these areas contain Annex habitat

Bats. A survey of the Macroom to Ballincollig section has been undertaken by the Cork Bat Group, who are a local voluntary conservation group. This survey identified 32 bat roosts and 8 bat species within the vicinity of the various routes. Of these, 6 are noted to be Internationally Important, one of which (the Lesser Horseshoe Bat) is an Annex 2 species under the EC Habitats Directive 1992. Three roosts are of particular note:

Two Lesser Horseshoe Bat roosts – one of these is at Dunisky on the Yellow route (previously identified by Matt Pickard) – the other location is not given

Soprano Pipistrelle bat roost – containing a colony of 1,500 individuals, an exceptionally large number. The exact location is not provided but it is understood to be on both the Purple and Red routes, so is likely to be close to Kame Cross Roads.

We requested that the Bat Group send us details of the locations of the roosts, and also an updated copy of their report. The Bat Group have subsequently stated that in order for us to receive this information, we would be invoiced £1,500.  Since we will be undertaking bat surveys (amongst other protected species) as part of the EIS surveys we declined their offer

Cultural heritage.  The Archaeological sub-consultants  have stated that in general, in terms of archaeology and built heritage their preferred route is the yellow, for the whole of the length of the route, provided that the 3 sites which are directly impacted in Ballymakeery can be avoided.

It should be noted that although Kilcrea Abbey is not directly impacted by any of the routes, the Blue route passes very close to the monument, which is owned by the Minister for Arts, Heritage, Gaeltacht and the Islands, and is considered of national importance. Passing so close to this monument is likely to have a severe detrimental impact on it’s setting. Due to the importance of this site, and the fact that it is an important tourist attraction, this is likely to be considered as a severe impact.

Of the other Environmental topics:

Agriculture: - Yellow is the preferred route for the Ballyvourney to Macroom and the Red route (Macroom to Ballincollig) as it takes less high quality land (although Yellow route is only marginally better for this section)

Planning – Routes which cross the Lee Valley contravene the policy of Cork County Council to maintain the shoreline of the Reservoirs free from development which may affect the scenic views

Noise - Not yet completed, as property information not available at that time for the new alignments

Air Quality – Not yet completed, as property information not available at that time for the new alignments

(Noise and Air Quality were not seen as governing constraints for initial route selection.)

Geotechnical

Preliminary site investigation for the purposes of Route Selection not required. Exact extent and depth of soft/peat areas remain uncertain but soft areas are fairly limited. Some probing of peat may be required. Given problems experienced by other jobs with respect to land access for site investigations it is expected that the N22 will have similar difficulties.

Foundations for structures: no problems envisaged for bearing/settlement criteria. Piles may be required depending on river crossing chosen.

Hydrogeology: issue of drying of wells due to alteration of groundwater regime around cuttings. Current vertical alignments limit lengths and depths of deep cuttings thus minimising this impact.
