Key information
Executive summary
This decision form sets out the programme of spend for the remaining Drain London Programme Budget over the rest of the Mayoral term (July 2018 – April 2020) and specifically seeks approval to focus this on the delivery of actions set out within the London Sustainable Drainage Action Plan (LSDAP), published by the Mayor in December 2016. This aligns with Objectives 5.1, 5.3 and 8.2 of the London Environment Strategy.
Note that the Drain London project has had one Mayoral Decision (MD455) and 4 Director Decisions (DD899, DD1250, DD1322 and DD2064) associated with it since 2010.
Decision
This will take total expenditure on the Drain London programme to £3.2m, exhausting the Drain London Programme Budget.
Part 1: Non-confidential facts and advice
The Drain London programme was originally set up in 2010 in response to the need to better understand and manage surface water flood risk in London. The project was awarded a £3,200,000 grant from Department for Environment, Food and Rural Affairs (DEFRA). The first stages of the programme delivered surface water flood risk mapping and management plans for all 32 London boroughs and the City of London. The programme also delivered detailed studies into 28 areas of high surface water flood risk and went on to deliver a range of pilot demonstration projects showing how sustainable drainage measures can be retrofitted into the urban environment.
The Drain London programme recognised that further and coordinated activity to retrofit Sustainable Drainage Systems (SuDS) was needed to make a significant change to the way that rainwater is managed in London. SuDS help to capture, use, delay the dispersal of, discharge or absorb surface water. Many types of SuDS can be green (green roofs, raingardens, SuDS tree pits, swales, etc.), therefore increasing SuDS across London will allow better management of rainwater and contribute towards the Mayor’s green cover targets. Although there is a preference to promote green SuDS measures there are other non-green SuDS (rainwater harvesting, permeable pavements and attenuation storage tanks) that can provide various benefits which will also be promoted where appropriate.
The London Sustainable Drainage Action Plan (LSDAP) was produced, consulted upon and officially launched in December 2016. The LSDAP looks to promote the retrofitting of SuDS to existing buildings, land and infrastructure and includes 40 actions identified at encouraging this across a wide variety of sectors.
The actions identified within the LSDAP directly contribute towards the delivery of the following London Environment Strategy Objectives:
5.1 – Make more than half of London’s area green by 2050
5.3 - Value London’s Natural Capital as an economic asset and support greater investment in green infrastructure
8.2 - Reduce risks and impacts of flooding in London on people and property and improve water quality in London’s rivers and waterways.
Since 2010 the Drain London programme has been overseen by the Drain London Board consisting of the GLA, Transport for London, the Environment Agency, Thames Water and London Councils. The focus of late has then been on publishing the LSDAP and the recruitment of a project manager to coordinate its delivery. The board has agreed the proposed spend profile included within this MD.
Previous decisions MD455, DD899, DD1250, DD1322 and DD2064 are relevant as these relate to the previous stages of the Drain London programme.
The current balance held in the Environment Drainage reserve for Drain London programme is £381,400 and this decision sets out the proposal for the expenditure of this amount in 2018/19 and 2019/20.
-
- All boroughs have surface water management plans (funded through Drain London) that identify the main flood risk areas and the GLA has data on sewer capacity and water quality. This evidence underpins all the LSDAP work and the measures boroughs install. The Drain London programme will continue to deliver actions to improve the understanding and delivery of surface water flood risk management and sustainable drainage, with the allocation of spending to be agreed by the Drain London Board (see para 1.5). Money will be spent on priority areas for surface water flood risk, poor water quality and constrained sewer capacity.
- Proposed project activities include:
-
- Cost details are set out in Part 2 to this decision, as to release these details at this stage would prejudice the commercial interests of the GLA.
- The SuDS research and pilot projects referenced above will be agreed by the Drain London Board prior to assigning funds. Note that these will always maintain a strong link to the London Environment Strategy’s aims.
Under Section 149 of the Equality Act 2010, as a public authority, the Mayor of London must have ‘due regard’ of the need to eliminate unlawful discrimination, harassment and victimisation as well as to advance equality of opportunity and foster good relations between people who have a protected characteristic and those who do not.
The Drain London programme and LSDAP outlined in this MD are heavily linked into the policies and proposals in the London Environment Strategy which has been informed by a full Integrated Impact Assessment, including a consideration of equalities.
This programme will primarily contribute towards meeting Proposal 8.2.3b (which includes the ambition for 200 hectares of impermeable surface in London to drain to SuDS by 2030), The projects listed in this MD look to maximise their positive impact on all Londoners including for example: reducing the risk of flooding, increasing access to green space, contributing to urban cooling, and reducing the health impact of air quality.
Projects delivered through this programme will continue to engage as many Londoners as possible to help to meet the needs of people sharing protected characteristics under Section 149 of the Equality Act 2010. Grant assessment criteria (de-paving) will aim to deliver projects in deprived wards; engaging people with disabilities; engaging those over 60 and under the ages of 16; engaging with different population groups including those with protected characteristics.
Grant application processes will require a statement about the organisations’ approach to equality and/or the submission of organisations’ equality policies.
Recipients of funding will be required to outline how projects will provide environmental and community benefit. This includes information on the intended beneficiaries. They will be required to advertise their volunteering opportunities via Team London where appropriate.
Key risks and issues
4.1 The Drain London programme is low risk and is fundamentally aimed at encouraging greater uptake of SuDS with a focus on reducing surface water flood risk whilst providing water quality, biodiversity and amenity benefits. The key risks and issues are set out in table below.
Links to Mayoral strategies and priorities
4.2 The Drain London programme and the LSDAP are referred to in the new draft London Plan, the London Environment Strategy and the Mayor’s Transport Strategy.
Impact assessments and consultations
4.3 The actions within the LSDAP form part of the proposals in the London Environment Strategy which has been informed by a full Integrated Impact Assessment. There are no specific impact assessments undertaken for the LSDAP. The LSDAP was subject to a 3-month public consultation exercise over autumn/winter 2015-6, with the majority of responses coming from London boroughs and other organisations with an established interest in drainage issues.
Mayoral approval is sought for expenditure of the remaining £381,400 Drain London Programme Reserve in 2018/19 and 2019/20 to implement the projects described in this MD, which will deliver actions detailed in the London Sustainable Drainage Action Plan (LSDAP). This will take total expenditure on the Drain London programme to £3.2m, exhausting the Drain London Programme Budget.
Detailed breakdown of the expenditure is set out in Part 2 to this decision.
The expected spend for 2018-19 is £156,400 and 2019-20 is £225,000. These amounts will be drawn down from reserves in the respective years.
