Summary of objectives to manage flooding

Objectives have been set by SEPA and agreed with flood risk management authorities. 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.

Local Plan District Local authority Main catchment Highland and Argyll The Highland Council Ardnamurchan coastal

Background

This Potentially Vulnerable Area is There are no major rivers in this area. approximately 79km2. It is located on However, there are several smaller the Ardnamurchan peninsula along the rivers such as the Dig Bhan and the Allt north east shore of Loch Sunart (shown Camas a Choirce. below). The A861 and B8007 pass through the area. There are fewer than 10 residential and non-residential properties at risk of flooding.

The Annual Average Damages are approximately £69,000 with the majority caused by coastal and river flooding.

River 42%

Coastal 48%

Surface water 11%

Summary of flooding impacts

Coastal flood risk is limited to short sections of coastline and mainly affects roads. River flood risk is limited to localised areas generally close to the outlets of the rivers, for example around Glenborrowdale.

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.

Roads potentially affected by flooding include the A861, B8044 and B8007. One designated cultural heritage site and areas of environmental importance are at risk. These include Special Areas of Conservation, Special Protection Areas, and Sites of Special Scientific Interest at Claish Moss and Kentra Moss, and Sound of Arisaig.

The damages associated with floods of different likelihood are shown in Figure 2. For this Potentially Vulnerable Area the highest damages are to roads and residential properties. The location of the impacts of flooding is shown in Figure 3.

History of flooding

Five floods have been recorded since 2001. In January 2001 blocked culverts and overflowing burns threatened properties in Glenborrodale.

287 Section 2 Highland and Argyll Local Plan District Objectives to manage flooding in Potentially Vulnerable Area 01/26

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 Sunart and Moidart Potentially Vulnerable Area.

Highland and Argyll Section 2 288 Local Plan District Actions to manage flooding in Potentially Vulnerable Area 01/26

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 Sunart and Moidart Potentially Vulnerable Area.
