South Dublin County Council N7 Newlands Cross Upgrade Environmental Impact Statement 13. COMMUNITY AND MATERIAL ASSETS 13.1 Introduction A new interchange is proposed for the Newlands Cross junction in Clondalkin. The existing signalised junction is the cause of much delay to traffic on the N7 Naas Road and on the Belgard / Fonthill Road (R113). Delays also affect cyclists and pedestrians, although severance is limited by the small amount of residential housing and the absence of many community facilities south of the N7. Arup Consulting Engineers Improvements to the Red Cow Interchange between the N7 and M50 are currently underway. Additional lanes are also in the process of being added to the M50. The proposed Newlands interchange will complement these developments by reducing delay and congestion in the area. Improved journey times will benefit businesses and people living and working in South Dublin. Journey amenity will also improve. This chapter examines journey patterns and identifies amenities in the area, including that of Newlands Golf Club. It considers the extent to which the community will be affected by the proposed interchange. 13.2 Community 13.2.1 Objectives and Methodology The purpose of the Community Assessment is to identify the potential impacts on local people and businesses in the vicinity of the proposed interchange. The assessment of the impacts of the proposed interchange, the With Scheme Scenario, is compared with that of the Do-Minimum (without) Scenario. It is important to understand that Do-Minimum does not exclude other confirmed or proposed developments going ahead and impacts of the scheme itself will be incremental to these. Relevant information consulted in the preparation of this report has included: • Demographic data currently published based on the 2006 Census together with comparison with more detailed data from the 2002 Census; • Drawings and photographs of the proposed interchange provided by ARUP; • Temporary construction diversion lay-out provided by ARUP. • Dublin street map and Ordnance Survey 1:50,000 map No. 50; • A review of secondary sources such as the South Dublin County Council Development Plan; • A count of pedestrians and cyclists at peak traffic and off-peak times. The community assessment of the road has been undertaken broadly in line with guidelines provided by the EPA Advice Notes on Current Practice in the Preparation of Environmental Impact Statements (2003), EPA Guidelines on the Information to be contained in Environmental Impact Statements (2002) and the NRA Environmental Impact Assessment of National Road Schemes - A Practical Guide (2006). In addition, reference is made to the guidelines provided on Community Effects in Part 8, Section 3 of the UK Design Manual for Roads and Bridges Volume 11 (DMRB) 1. December 2007 Page 201
South Dublin County Council N7 Newlands Cross Upgrade Environmental Impact Statement Arup Consulting Engineers 13.2.1.1 Treatment of Impacts Impacts can be Positive, Negative or Neutral. Their significance is assigned as Imperceptible, Slight, Moderate, Significant and Profound. Significance depends, among other considerations, on the nature of the environment affected, the duration of an impact, and the probability of its occurrence. It often follows that impacts of a socio-economic nature are a function of: a) the scale of the impact itself, b) the numbers of people likely to be affected, and c) the impact on vulnerable or sensitive groups. A study of socio-economic impacts generally addresses impacts at the community level rather than for individuals or identifiable properties. Impacts are presented as they would affect the most affected subset of the population, although clarification is provided in both the text and the summary table (see Appendix A13.1) as to the absolute numbers affected. The assessment of impacts at a local level has focused on the communities adjacent to, or in the general environs of, the Scheme. Particular emphasis has been given to the impacts on local vehicle journeys, pedestrians, cyclists and local residents in terms of the following four headings: • Journey characteristics: an assessment of the impact of the proposed route on journey time, journey time reliability and travel patterns. • Community severance: an assessment of the impact of the proposed route with regard to community severance, including impacts on the use of community facilities, particularly those used by older people, children or other vulnerable groups. The category includes both new severance and relief from existing severance. • Amenity: An assessment of the impact on journey amenity arising from traffic conditions and people’s exposure to traffic (i.e. safety, noise, dirt, air quality). The category also includes impacts on sites used for amenity purposes and general impacts on local quality of life. • Economic impacts: an evaluation of the proposed interchange in the context of economic prospects and employment. 13.2.1.2 Journey Characteristics New roads have an inevitable effect on local journey patterns, length and duration for vehicle journeys, journeys by public transport, bicycle and for pedestrians. Each is discussed in turn in the report. Assessment of journey patterns, length and duration is inevitably dependent on precisely where an individual journey originates and ends, when it is undertaken (e.g. within or outside peak hours) and by whom it is undertaken, e.g. vulnerable groups. Impacts have been assessed in accordance with the significance criteria outlined in Table 13.1, with positive impacts resulting from a decrease, and negative impacts resulting from an increase in journey length or duration.
