Cycleway Required New Sections of Seawall

New watermain laid during excavation Sea Defence Element Added to Seawalls

Results in Greater Efficiency in Planning / Design / Procurement

Less Disruption to the SAC / SPA and Residents Better Value for Money

works to improve existing seawall;

  • Proposed services include improved drainage system, watermain and upgraded

public lighting.

Overall

  • Streetscape improvement – new road surface, footpaths, traffic signals, cycle track and

upgraded public lighting throughout the scheme;

Proposed Sea Wall Finishes

Proposed wall finishes are as follows:

  • At sections of poured concrete wall

– Smooth F4 concrete finish with new coping.

  • At all other sections of wall (both where existing wall is rebuilt or raised,

and where new masonry wall is built)

– Ready mixed smooth render finish with new coping.

  • Options currently being looked at to amend design to improve aesthetics
  • f the newly completed wall.

Wall Heights between Junctions along Route

Wall height adjustments are as follows:

  • Bull Island Junction to Seafield Road East Junction: Level adjustment of up to 276mm (11

inches). First 25m no level change. New average wall height = 540mm (21 inches).

  • Seafield Road East Junction to Dollymount Park Junction: Level adjustment up to 120mm

(5 inches) and new wall construction. New average wall height = 580mm (23 inches).

  • Dollymount Park Junction to Doyle’s Lane Junction: New wall construction to match

existing wall heights. New average wall height = 690mm (27 inches).

  • Doyle’s Lane Junction to Dollymount Avenue Junction: New wall construction for 55

metres to match existing levels, no level adjustment to retained wall. New average wall height = 450mm (18 inches).

  • Dollymount Avenue Junction to The Oaks Junction: Wall level relatively unchanged with

new coping to be installed. New average wall height = 700mm (28 inches) with maximum wall height = 975mm (39 inches) – same as existing.

  • The Oaks Junction to Mount Prospect Avenue Junction: No level change. New average

wall height = 800mm (32 inches).

  • Mount Prospect Avenue Junction – Naniken Stream: Level adjustment of 450mm-

690mm (18-27 inches). New average wall height = 840mm (33 inches) with maximum wall height = 1,138mm (45 inches) including 75mm (3 inch) coping.

  • Note: the section of wall just south of Mount Prospect Avenue which is not being adjusted is currently at a height

up to 975mm (38.4 inches). The max height of our current wall north of this is 1,063mm (42 inches) excluding coping, which would be 1,138mm (45 inches) allowing for a 75mm (3 inch) coping.

Howth Road to Baldoyle Road

  • Old Sea Wall Height for Comparison

Distance from Howth Road to Baldoyle Road is 2.1km (1.3 miles) – almost identical in length to this scheme. Old sea wall is 0.7m (27.6 inches) to 1m (39.4 inches) high along the 2.1km length. Depending on the relative road level the wall does restrict views of the foreshore at times although Howth is clearly visible. This length of road is much straighter and does not have a bend or camber on the road like there near the pond at St. Anne’s Park that would restrict views for car drivers even further.

SAFETY BENEFITS

SAFETY

Reduced Carriageway Width (2 x 3m)

Upgraded Junctions along route

Improved Driver Behaviour Reduced speed limit at north end 60km/h → 50km/h Reduced speeds - 85%ile currently 57.3km/h

Removal of Driver/Cyclist Conflict

slide-41
SLIDE 41

SAFETY BENEFITS

Reasons for Buildouts:

  • Improve

visibility and safety for pedestrians crossing junctions.

  • Improve visibility for drivers entering
  • r exiting side streets.
  • Make it easier for visually and mobility

impaired people to cross the junction, as well as people will child buggies.

  • Prevent drivers from parking too close

to corners thereby blocking visibility for pedestrians and other drivers.

Environmental Measures

  • Appropriate Assessment carried out for the scheme
  • Environmental Clerk of Works appointed by DCC
  • Project Ecologist engaged by Contractor

– Environmental Management Plan – Grassland Management Plan – Method Statements for Works on Lagoon – Ongoing environmental monitoring

  • Liaison with NPWS and BirdWatch Ireland
  • Mitigation Measures Implemented

– Screen erected between Works and Lagoon – No Lagoon Works during winter to facilitate wintering birds
