EUR1.2m deal boost for boundary.
The figures are contained in a proposal to the Boundary Commission drawn up by the County Manager.
Councillors have unanimously accepted the document but are adamant that further extensions are out of the question.
Under the proposal from Limerick County Council, EUR200,000 will be paid annually by the city authority for six years.
The figure was agreed with the council as a means of making up the loss of revenue from rates.
The agreed boundary extension represents a 50 per cent increase in the area of the city.
