Gardaí say the re-opening of Stepaside garda station in Dublin may only be a temporary measure.
A new report claims it could provide cover while a new station is built elsewhere.
Acting Commissioner John O'Driscoll says serious consideration should be given to building in nearby Cherrywood which is growing rapidly.
There was widespread controversy when Stepaside garda station, in the Transport Minister Shane Ross's constituency, was chosen for re-opening despite not being a priority for senior members of the force.
The re-opening has been mired in controversy with suggestions its re-establishment was only assured by the intervention of Minister Ross.
He has denied any stroke politics took place, and the gardaí have written to the Office of Public Works (OPW) to start the process of re-opening Stepaside and five other former garda stations.
But in that report they say it may only be a temporary measure.
It is estimated by 2030 there will be an additional 7,700 homes in the Cherrywood area, and a population of 30,000 left with limited garda cover.
Acting Commissioner O'Driscoll notes timelines would be important, and if it were to take until 2030 to build a new station at Cherrywood, nearby Stepaside could be opened on an interim basis to provide cover.
The gardaí say it would be prudent to establish if a new station is viable in Cherrywood before committing to re-opening Stepaside.
