The CEO of Limerick City and County Council is to leave his post in August.
Conn Murray has been boss of the amalgamated local authority for the past five years, and was chief executive of the separate Limerick city and county councils prior to that.
Mr Murray, a native of Co Meath, has served on nine different local authorities over his career and has served as city manager in Waterford and county Manager in Louth, before being appointed as chief executive of Limerick city and Limerick county councils in 2012.
Making the announcement to the Mayor of Limerick, Councillor Michael Sheahan, and to staff this morning Mr Murray said he had had the pleasure of serving the public in many different capacities over the past 40 years as he developed his career in local government.
"The last seven years in Limerick have, on a personal and professional level,been the most rewarding. As of 14 August next my contract of employment with Limerick City and County Council ends and the time is right for me to move on," he said.
Responding to his announcement Cllr Sheahan said Mr Murray will be recognisedas among the key architects of the incredible economic renaissance that Limerick has undergone over the past five years.
He said he had led the amalgamation of the local authorities and with it the biggest single change management programme in local government history.
"Initiatives like Limerick Twenty Thirty, which is going to be transformative for the city, advancing the Regeneration programme, the creation of the largest economic unit in any local authority and implementing Irelands first National City of Culture programme all came under his watch," he said.
Limerick Twenty Thirty had seen over 15,000 new jobs and €2 billion of planned investment for Limerick in the past five years.
