Locally leading on flood management. Mapping and registering defence assets including those in private ownership. Designating third party assets. A duty to investigate the causes of flooding. The technical approval body for Sustainable Drainage Systems (SuDS). The management and maintenance of adopted SuDS systems. Tameside Council must develop, maintain, and monitor a strategy for local flood risk management in its area for the following forms of flood risk: surface runoff groundwater and ordinary watercourses The strategy sets out how Tameside Council will take on the challenges posed by flood risk by setting local objectives and stating how these will be achieved. It also reflects the needs and priorities identified by local people, business and flood risk partners. The strategy sets out: The risk management authorities in Tameside. The flood risk management functions that may be exercised by those authorities in Tameside. The objectives for managing local flood risk. The measures proposed to achieve those objectives. How and when the measures are expected to be implemented The assessment of local flood risk for the purpose of the strategy. How and when the strategy is to be reviewed. How the strategy contributes to the achievement of wider environmental objectives. It has been determined that the Strategic Environmental Assessment (SEA) Directive applies to the draft strategy.
Developing SEA objectives The following SEA objectives and environmental issues were developed from the relevant programmes and environmental objectives. , SEA number SEA Objective Theme SEA Objectives Environmental Issues Most Relevant Plans and Programmes 1 Flood Risk To minimise annual flood damage to property and businesses. To improve knowledge and understanding of flood risk. To protect critical infrastructure. To protect and maintain existing risk assets. To maintain and improve water run-off. Pluvial flooding is the main source of flooding. There is additional flood risk in some areas from fluvial flooding. 4,553 properties are predicted to be at risk of deep surface water flooding (300mm) in an extreme rainfall event (1 in 200 years) GMSWMP PFRA SFRA 2 Water Quality To maintain and enhance water quality and water resources. To promote sustainable drainage systems. Pollution from development and highways entering the water environment through surface water sewers and drains. Control of pollution from contaminated land. WFD 3 Biodiversity and Natural Environment To protect and improve our natural environment. To grow a green economy, and reconnect people and nature. To protect and enhance biodiversity Communities are deprived of high quality open spaces and linkages, such as urban river ecosystems; those that exist are often fragmented. Encroachment by development and In-fill development is causing loss of open space and habitats. GM Biodiversity Action Plan GM Green Infrastructure Framework WFD
