Goals and outcomes

Investment objectives of the Outline Business Case (OBC)

1) To reduce the threat of coastal flood and erosion risk to people and
property with due consideration of SMP2 policy to ensure the long-term resilience and vitality of the community.

2) To support, and where possible enhance, recreation and amenity value of the local area

3) To maintain, and where possible enhance, natural and historic environments.

4) To ensure marine amenity activities can continue to grow

5) Ensure an affordable and deliverable whole life option through a partnership approach and contributions.

Critical success factors

Strategic fit and business needs – This means adapting to climate change, delivering on the national flood strategy plan’s objectives, delivering on the Wellbeing Act’s goals, consideration of the SMP2 policy, and providing local amenity and recreational benefits.

Value for money – Protecting and enhancing the local economy by avoiding flood damages. The scheme must have a positive cost-benefit ratio meaning the money spent on the scheme must be less than the value of property it is defending. 

Potential achievability – Ensuring the local authority has the resources to manage the project(s), ensuring all local stakeholders are engaged and supportive of the scheme, and ensuring that there are adequate labour resources and manpower to construct the scheme in budget. 

The Wellbeing of Future Generations (Wales) Act -2015 (key objectives)

A resilient Wales: Reducing flood risk whilst enhancing the environment. The project will reduce flooding to 79 properties in a 1 in 100 year flood event up to 2050, and construction of infrastructure will be undertaken in an environmentally-responsible manner. Throughout the project’s lifecycle, opportunities for environmental enhancements will be sought.

A healthier Wales: Safeguarding the health and wellbeing of the public. The public space between the shore and Beach Road is used by the community, and therefore it is important that enhancing this space is given consideration. Enhanced flood protection will also reduce the stress and worry residents may have regarding flooding.

A more equal Wales: Ensuring safe, sustainable construction, and strengthening/regenerating communities. Once an option is confirmed, due consideration can be given to sustainable construction, and the carbon output of the construction will be captured. Redevelopment is being merged with a broader, city-wide scheme.

A Wales of cohesive communities: Maintenance of public footpaths and fields. The scheme will look at opportunities to enhance the green space along the shore, and will make allowances for the coastal cycleway.

Local Strategy

Gwynedd Council published the Local Flood Risk Management Strategy in 2013 which contains the following principles:

  • Embrace a collaborative, local approach to managing the risks and consequences of flooding and coastal erosion, and the provision and funding of innovative schemes to reduce those risks.

  • Increase the understanding of the risks of flooding and ensure everyone in Gwynedd is aware of these risks, and understands their responsibility to protect their own property from flooding.

  • Ensure better, more frequent communication between everyone involved in the management of flood risk.

  • Ensure new development fully embraces sustainable drainage principles and does not increase flood risk.

  • Develop and maintain effective emergency plans and responses to flood incidents.

  • Encourage effective maintenance of all structures and watercourses.

The National Flood Risk Management Strategy

This document sets out the policies on flood and coastal erosion risk management, and establishes the following key objectives:

  • Reducing the consequences for individuals, communities, businesses and the environment from flooding and coastal erosion.

  • Raising awareness of and engaging people on flood and coastal erosion risk.

  • Providing an effective and sustained response to flood and coastal erosion events prioritising investment in the most high-risk communities.

Welsh Government Strategy

As part of the Welsh Government’s Coastal Risk Management Programme (CRMP), money is being allocated to support infrastructure:

  • £150 million investment (75% from Welsh Government and 25% from local authorities).

  • Enabling adaptation to climate change and implementation of the second shoreline management plan’s recommendations.

  • Achieving wider additional and community benefits alongside reduced flood and erosion risk.

  • Contribute to the Wellbeing of Future Generations Act (especially objectives 6, 7, and 8).
