Concerns about the impact of the scheme on the scenery at the Wicklow Gap led to ESB, whose chairman and chief executive at the time, Tom Murray, was an enthusiastic supporter of the project, engaging the services of landscape architect Sylvia Crowe. She recommended that the upper reservoir be camouflaged by planting vegetation on its embankments and that the works on the lower reservoir at Lough Nahanagan be designed to fit into the background of rock. The siting of the transmission lines that would connect Turlough Hill to the electrical grid was a matter of some controversy. Objections to the lines, planned to run from Turlough Hill to the village of Hollywood, came from several quarters, including Bord Fáilte, the Irish tourist board. In the end, it was decided that they would run underground from Turlough Hill for c. , to preserve the view at the Wicklow Gap, before emerging overground on pylons along the King's River to Hollywood. This added £600,000 to the cost of the project.
