In the first instance, the optimal usage, management and development of Dublin City Council's land bank is a matter for the Council itself. In relation to the specific land referenced, I understand that the Council is working on a Depot Consolidation Project, involving the rationalisation of existing depots, into two main locations, to achieve operational efficiencies and to release lands for more appropriate uses.
My Department is working in partnership with the Council to ensure the optimal delivery of new social and affordable homes from its residential land bank. To this end, and as part of the new approach to active State land management under the Rebuilding Ireland Action Plan for Housing and Homelessness, details of the Council's residential land bank were published on the Rebuilding Ireland Housing Land Map, available at http://rebuildingireland.ie/news/rebuilding-ireland-land-map/ .
Information on the Council's social housing developments, as at end Q3 2017, is available in the Construction Status Report which is available at http://rebuildingireland.ie/news/quarter-3-social-housing-construction-status-report/ . I expect to publish an updated report shortly, reflecting the position at end 2017.
My Department is also working closely with Dublin City Council on sites to help develop large mixed-tenure sites, for example, at O'Devaney Gardens and Oscar Traynor Road. In total, these two sites can accommodate the delivery of over 1,200 newly constructed homes.
