These are the aims for managing local flood risk. The objectives have been grouped in three main ways: by reducing risk, avoiding increasing risk or accepting risk by maintaining current levels of management. Objectives Many organisations, such as Scottish Water and energy companies, actively maintain and manage their own assets including their risk from flooding. Where known, these actions are described here. Scottish Natural Heritage and Historic Environment Scotland work with site owners to manage flooding where appropriate at designated environmental and/or cultural heritage sites. These actions are not detailed further in the Flood Risk Management Strategies. Summary of actions to manage flooding The actions below have been selected to manage flood risk.

Figure 1: Annual Average Damages by flood source Summary of flooding impacts The highest risk of flooding is in Monifieth from the Monifieth Burn. Monifieth is also notably impacted from surface water flooding. The risk of flooding to people, property, as well as to community facilities, utilities, the transport network, designated sites and agricultural land is summarised in Table 1. The damages associated with floods of different likelihood are shown in Figure 2. For this Potentially Vulnerable Area the highest damages are to residential properties followed by damages to non-residential properties. The location of the impacts of flooding is shown in Figure 3. The figures presented for Annual Average Damages include damages to residential properties, non-residential properties, transport and agriculture.

Tay Estuary and Montrose Basin Local Plan District Section 2 122 Objectives to manage flooding in Potentially Vulnerable Area 07/10 Objectives provide a common goal and shared ambition for managing floods. These objectives have been set by SEPA and agreed with flood risk management authorities following consultation. They were identified through an assessment of the underlying evidence of the causes and impacts of flooding. Target areas have been set to focus actions; they do not necessarily correspond to areas at risk in SEPA’s flood map. The objectives below have been set for Monifieth Potentially Vulnerable Area. Reduce economic damages to residential and non-residential properties and risk to people in Monifieth caused by flooding from the Monifieth Burn Indicators: Target area: • 640 people • £520,000 Annual Average Damages from residential properties • £26,000 Annual Average Damages from non-residential properties Image found and displayed.

For 07/10 there are 30 residential properties at risk and Annual Average Damages of £44,000. Tay Estuary and Montrose Basin Local Plan District Section 2 124 Actions to manage flooding in Potentially Vulnerable Area 07/10 Actions describe where and how flood risk will be managed. These actions have been set by SEPA and agreed with flood risk management authorities following consultation. Selection of actions to deliver the agreed objectives was based on a detailed assessment and comparison of economic, social and environmental criteria. The actions shaded and then described below have been selected as the most appropriate for Monifieth Potentially Vulnerable Area. Selected actions Flood Natural flood New flood Community Property level Site protection protection management warning flood action protection plans scheme/works works groups scheme Flood Natural flood Maintain flood Awareness Surface water Emergency protection management warning raising plan/study plans/response study study Maintain flood Strategic Flood Planning Self help Maintenance protection mapping and forecasting policies scheme modelling Action (ID): NEW FLOOD WARNING (70540010) Objective (ID): Reduce overall flood risk (7054) Delivery lead: SEPA Status: Not started Indicative delivery: 2016-2021 Description: The area under consideration includes properties in Monifieth affected by flooding from the Monifieth Burn. Further feasibility assessment will be required to assess delivery potential. A local authority study has been proposed for this area which can inform the scoping exercise once complete. Action (ID): FLOOD PROTECTION STUDY (70230005) Objective (ID): Reduce economic damages to residential and non-residential properties and risk to people in Monifieth caused by flooding from the Monifieth Burn (7023, 7024) Delivery lead: Angus Council National: Within local authority: Priority: 24 of 168 2 of 6 Status: Not started Indicative delivery: 2016-2021 A flood protection study has been recommended for Monifeith to Description: assess whether flood storage, flood defences and sediment management could reduce flood risk. The study should take a catchment approach and consider the potential benefits and disbenefits and interaction between actions upstream and downstream. 125 Section 2 Tay Estuary and Montrose Basin Local Plan District Potential impacts Economic: The study could benefit 243 residential properties and 15 non- residential properties at risk of flooding in this location, with potential damages avoided of up to £17 million. Social: Social impacts will depend on the outcome of the study and recommended actions. A reduction in flood risk would have a positive benefit to the health and wellbeing of the community and socially vulnerable people located within the study area. In addition the study could benefit two utilities and one railway
