To ask Her Majesty’s Government how many construction-related road vehicles and of what sizes and types are expected to access each of the main Olympic sites in (a) 2009, (b) 2010, (c) 2011, and (d) 2012. [HL5071]

We expect the construction period, when the Olympic Delivery Authority (ODA) is building the Olympic Park, venues and infrastructure, to be largely completed by mid-2011.

The ODA records the number of vehicles entering the Olympic Park but does not record data relating to type or size of road vehicle. To date, there have been 270,000 two-way lorry movements.

Based on the forecast average of 15,700 two-way movements per month—a projection made in 2007 as part of the business case in support of the logistics project—the ODA predicts the following construction-related two-way movements during the periods:

The ODA also records the number of vehicles accessing the off-park venues—for example, Broxbourne, Eton Dorney—but due to the significantly smaller scale of these sites does not predict future vehicle movements accessing these venue sites.

The ODA has committed to ensuring 50 per cent of materials by weight will be delivered by either rail or waterways, significantly reducing the number of construction-related vehicles from the road network.

To ask Her Majesty's Government how many construction-related road vehicles and of what sizes and types accessing the main Olympic sites are expected to travel along which key roads in Greater London in (a) 2009, (b) 2010, (c) 2011, and (d) 2012. [HL5072]

We expect the construction period, when the Olympic Delivery Authority (ODA) is building the Olympic Park, venues and infrastructure, to be largely completed by mid-2011.

All road deliveries have to go to one of the two off-site logistics centres, at Barking and Chigwell, prior to arriving at the Olympic Park. At those centres all deliveries are assigned an arrival time slot at the Olympic Park entrance plazas. The ODA has worked with the Metropolitan Police and the local boroughs to develop suggested route maps for all vehicles travelling from the logistics centres to the Olympic Park. These designated routes ensure all road deliveries remain on the A road network, using the A11, A12 and A13.

While the ODA records the number of vehicles entering the Olympic Park it does not record data relating to type or size of road vehicles, nor the specific travel routes taken by construction-related road deliveries before arriving at the logistics centres.

The ODA has committed to ensuring that 50 per cent of materials by weight will be delivered by either rail or waterways, significantly reducing the number of construction-related vehicles from the road network.

To ask Her Majesty's Government what monitoring arrangements the Olympic Delivery Authority has in place to measure air quality along key public roads used by construction-related road traffic accessing each of the main Olympic sites; and whether that monitoring shows that European Union limit values for particulate matter and nitrogen dioxide are being met along such roads. [HL5073]

As part of the environmental impact assessment submitted in support of the outline planning applications in 2007, the Olympic Delivery Authority (ODA) undertook detailed air dispersion modelling in order to understand the effects of the Olympic Park development on air quality. The results showed that effects on air quality from construction-related traffic would be negligible and that year-on-year long-term concentrations of traffic-derived air pollutants would be reduced as a result of the increasing proportion of more stringent “Euro” emission-class vehicles in the national vehicle fleet.

The ODA does not monitor air quality along the key public roads used by construction-related road traffic. Generally, local authorities have responsibility for monitoring the ambient air quality within their boroughs through a review and assessment process. Any significant construction activity, such as the Olympic Park development, would be taken into account in any such assessment. In addition, the ODA publishes the monitored data for noise and dust each month on the London 2012 website.

The ODA does, however, have an extensive monitoring network around the Olympic Park site, but this is focused on construction activity and not road deliveries to the site. However, as the Olympic Park site is within the London low emission zone, all site delivery vehicles must comply with Euro III emission standards. The ODA also encourages its contractors’ delivery vehicles to comply with Euro IV standards.

Furthermore, the ODA has committed to ensuring that 50 per cent of materials by weight will be delivered by either rail or waterways, significantly reducing the number of construction-related vehicles from the road network.
