	Appraisal and design work started in January 2013 with construction beginning in 2015. The flood basin and wetland will be fully operational by June 2017 at a cost of approximately £9 million.

	Working with local community, the University of Salford, Salford City Council, the Environment Agency identified an opportunity to work together to use land owned by University and Council to create a new flood basin to help reduce flood risk to people and property just downstream, but also create a new urban wildlife asset in the heart of city, interlinking with neighbouring River Irwell local wildlife site and Kersal Dale Local Nature Reserve on opposite bank.

	Once the overall joint agreement for construction of new flood basin and wetland was agreed with all parties, and initial meetings with local community groups to seek their views, the Agency brought in the expertise of the Wildfowl and Wetlands Trust to help develop detailed designs and maintenance plan for new 5.5Ha urban wetland		Once the overall joint agreement for construction of new flood basin and wetland was agreed with all parties, and initial meetings with local community groups to seek their views, the Agency brought in the expertise of the Wildfowl and Wetlands Trust to help develop detailed designs and maintenance plan for new 5.5Ha urban wetland

			Community involvement - Community consultation, Community Events, River open days; River Walks; Bioblitz event; Education events, School Tours.
	\|Monitoring surveys and results=The overall scheme has an integrated maintenance and management plan, while wetland has separate maintenance and management plan written by Wildfowl & Wetlands Trust and with prime focus of this being simplicity of management. With both plans integrated as part of site’s long term maintenance, this will ensure as the site develops and establishes, appropriate management will be conducted by agreed respective parties, to ensure in the long term the flood basin remains a functioning flood risk asset, but also an important new local wildlife and amenity resource for future.		\|Monitoring surveys and results=The overall scheme has an integrated maintenance and management plan, while wetland has separate maintenance and management plan written by Wildfowl & Wetlands Trust and with prime focus of this being simplicity of management.

	The new wetland is also attracting interest from local monitoring groups, including Greater Manchester birders through Winter Wetland Bird Blitz organized by Greater Manchester Ecology Unit and results will be updated to the Greater Manchester Records Centre.

	The University of Salford are also keen to monitor the wetland as part of their future courses for environmental studies.		The University of Salford are also keen to monitor the wetland as part of their future courses for environmental studies.

	\|Lessons learn=Some of the issues faced as part of project was to show it was feasible to construct a new wetland within an Agency flood basin without undermining it’s integrity and primary function, and ensuring the wetland had sufficient water to support the varied priority wetland habitats sought. This was achieved by undertaking groundwater monitoring and ground investigations, with results fed back into design.		\|Lessons learn=Some of the issues faced as part of project was to show it was feasible to construct a new wetland within an Agency flood basin without undermining it’s integrity and primary function, and ensuring the wetland had sufficient water to support the varied priority wetland habitats sought. This was achieved by undertaking groundwater monitoring and ground investigations, with results fed back into design.
	Another essential element of the wetland design was to ensure that it would be relatively simple to manage, i.e., by ensuring good vehicular access, and ensuring new wetland habitats were easily maintainable by local conservation groups and council, and reduced risk of competition between wetland habitat types.

	The urban wetland is located in the lower Irwell; a catchment that has significant infestations of invasive non-native species. Therefore an invasive control programme was essential, and integrated as part of construction works. Also a long term monitoring and control programme will be adopted as part of overall capital scheme maintenance.
