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.

Summary of flooding impacts There is a risk of coastal flooding in the south west of the area where the Balloch Burn and the Moneypool Burn converge to form the Ferry Burn in Creetown. The Ferry Burn subsequently discharges to the River Cree, which is tidal at this location. Coastal flooding is predicted to affect a number of residential and non-residential in the vicinity of Mill Street, Harbour Street, Norris Street and Silver Street. River flooding is mostly attributed to the Moneypool Burn and the Balloch Burn. In rural reaches of these watercourses flooding is restricted to a relatively narrow corridor of mainly agricultural land or woodland and a 1km stretch of Chain Road. Within the lower reaches in the urban area of Creetown, a number of residential and non-residential properties are at risk of river flooding. Within this Potentially Vulnerable Area it is estimated that climate change will increase the number of residential properties at risk of flooding from approximately 90 to 130 and the number of non-residential properties from approximately 20 to 30. The risk of flooding to people and property, as well as to community facilities, utilities, the transport network, designated sites and agricultural land is summarised in Table 1. The figure shows almost all impacts are predicted in Creetown. People, non- residential properties and roads are shown to be at risk. Solway Local Plan District Section 2 198 The damages associated with floods of different likelihood are shown in Figure 2. Residential properties affected by coastal and river flooding experience the highest economic impact at approximately 80% of the damages. Non-residential properties also provide a notable portion of the damages. The location of the impacts of flooding is shown in Figure 3. 1 in 10 1 in 200 1 in 1000 High likelihood Medium likelihood Low likelihood Residential properties (total 50 90 120 300) Non- residential properties (total <10 20 20 30) People 120 200 250 Community 0 0 0 facilities Utilities assets 0 0 0 Transport links - 0.9 1.2 1.3 roads (km) Environmental designated areas <0.1 <0.1 <0.1 (km2) Designated cultural heritage 1 1 1 sites Agricultural land 2 0.3 0.4 0.4 (km ) Table 1: Summary of flood impacts1 Figure 2: Damages by flood likelihood 1 Some receptors are counted more than once if flooded from multiple sources 199 Section 2 Solway Local Plan District Figure 3: Impacts of flooding History of flooding There has been little flooding reported within this area. However, coastal flooding did occur on 3 January 2014 and affected five properties. Flash flooding in Creetown occurred on July 2015 impacting properties. Solway Local Plan District Section 2 200 Objectives to manage flooding in Potentially Vulnerable Area 14/17 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 Creetown Potentially Vulnerable Area. Reduce the risk of river and coastal flooding to residential properties in Creetown Indicators: Target area: • 90 residential properties • £270,000 Annual Average Damages Image found and displayed.

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 Creetown Potentially Vulnerable Area.

This study should build on from the previous shoreline management plan to investigate flooding and coastal erosion, wave overtopping and the current coastal protection offered. The study may focus in detail on Potentially Vulnerable Areas however it could also look at the risk to other areas. The study will help to develop an understanding of coastal issues and identify where further work may be required to mitigate against flooding. Potential impacts Economic: There are 259 residential properties and 64 non-residential properties at risk of flooding over the extent of this study. The potential damages avoided over this area are estimated to be up to £26.1 million. Social: A reduction in flood risk would have a positive benefit to the health and wellbeing of the community. Natural flood management actions can restore and enhance natural environments and create opportunities for recreation and tourism. Solway Local Plan District Section 2 202 Environmental: Flood protection studies should consider the positive and negative impacts of proposed actions on the ecological quality of the environment. To be in accord with the flood risk management strategy, the responsible authority should seek to ensure as part of the study that the Solway coastal study will not have an adverse effect on the integrity of the Loch of Inch and Torrs Warren Special Protection Area, Upper Solway Flats and Marshes Special Protection Area, Luce Bay and Sands Special Area of Conservation, and Solway Firth Special Area of Conservation. There is the potential for impacts on several coastal Sites
