Policy 5.20 Aggregates
A The Mayor will work with all relevant partners to ensure an adequate supply of aggregates to support construction in London. This will be achieved by:
1 encouraging re-use and recycling of construction, demolition and excavation waste within London
2 extraction of land-won aggregates within London
3 importing aggregates to London by sustainable transport modes.
B The Mayor will work with strategic partners to achieve targets of:
a 95 per cent recycling/re-use of construction, demolition and excavation waste by 2020
b 80 per cent recycling of that waste as aggregates by 2020.
C London should make provision for the maintenance of a landbank (i.e. seven years’ supply) of at least 5 million tonnes of land won aggregates throughout the plan period until 2031.
D LDFs should make provision for the maintenance of a landbank (i.e. seven years’ supply) of at least 5 million tonnes of land won aggregates throughout the plan period to 2031 by a landbank apportionment of:
a at least 1.75 million tonnes to LB Havering
b at least 0.7 million tonnes to LB Redbridge
c at least 1.75 million tonnes to LB Hillingdon
d at least 0.7 million tonnes to LB Hounslow
E Mineral planning authorities in London should:
a identify and safeguard aggregate resources in LDFs
b support the development of aggregate recycling facilities, subject to local amenity conditions.
F To reduce the environmental impact of aggregates, LDFs should;
a ensure that appropriate use is made of planning conditions dealing with aftercare, restoration and re-use of minerals sites following extraction
b safeguard wharves and/or railheads with existing or potential capacity for aggregate distribution
c minimise the movement of aggregates by road and maximise the movement of aggregates via the Blue Ribbon Network
d develop policies that support the protection and enhancement of aggregates recycling facilities.
5.90 London needs a reliable supply of construction materials to support continued growth. These include land-won sand and gravel, crushed rock, marine sand and gravel, and recycled and alternative materials. Most aggregates used in the capital come from outside London, including marine sand and gravel and land-won aggregates, principally crushed rock from other regions. There are relatively small resources of workable land-won sand and gravel in London.
5.91 The Mayor supports the Government’s objective of achieving an essential level of supply in the most sustainable fashion, in order to ensure a good supply of locally sourced land-won aggregates. For the 2008 London Plan, the London Aggregates Working Party advised the Mayor that an annual output of 1.0 million tons per annum (mtpa) of land-won sand and gravel, sub-regionally apportioned 50:50 between boroughs in east and west London, was more realistic than the 1.1 mtpa proposed in the 2003 guidelines. This was accepted by the Mayor to inform London policy and was agreed by the Secretary of State.
5.92 The previous Government’s land-won sand and gravel guidelines for London for the period 2005-2020 proposed 1.1 mtpa. Recent monitoring suggests that this target remains very challenging for London, and the Mayor is not persuaded that setting the target suggested in the 2009 guidelines would actually increase production. Accordingly, and following discussions with boroughs and the industry on reserve levels, plan allocations and deliverability, the Mayor supports a realistic landbank figure (i.e. seven years supply) of at least 5 million tonnes of land-won aggregates for London throughout the plan period, apportioned to boroughs as set out in Policy 5.20D.
5.93 There remains some potential for extraction beyond the boroughs identified in the London Aggregates Monitoring report, including within the Lee Valley. Other boroughs with aggregates resources should consider opportunities in line with the policies in the plan. Adverse impacts on European biodiversity sites as a result of aggregates activities should be avoided.
5.94 Aggregates are bulky materials and LDF policies should maximise their use and re-use and minimise their movement, especially by road. Policy 5.3 on sustainable design and construction will be important in helping to reduce the demand for natural materials. The objective of proximity dictates the best and most local use of materials that can be extracted in London. Boroughs should safeguard both existing, planned and potential sites for all the uses and activities identified for safeguarding in paragraph 143 of the NPPF. Sites for depots may be particularly appropriate in preferred industrial locations and other employment areas. Existing and future wharf capacity is essential, especially for transporting marine-dredged aggregates, and should be protected in accordance with Policy 7.26.
5.94A The NPPF in paragraph 145 calls on mineral planning authorities to maintain a steady and adequate supply of aggregates by preparing an annual Local Aggregates Assessment (LAA). The four boroughs identified in Policy 5.20 will prepare either their own or joint LAAs. The Mayor does not consider that it would be proportionate or reasonable for the other 29 boroughs to produce their own LAAs, but that production of a joint LAA would be appropriate.
