Like the 6m by 3m billboard outside the Joondalup Library, it is part of the Inside-Out Billboard project.
The billboards are used to display commissioned work from artists taking part in the annual Community Art Exhibition and Community Invitation Art Awards.
Councillors were presented with 13 potential sites in the City centre including a mixture of freestanding, wall-based and rooftop billboards.
Previous sites considered included the Joondalup Civic Centre commercial office development site at Central Walk and Boas Avenue, opposite Medicare on Reid Promenade and the roof of Paddy Malone�s or the City’s administration building.
In assessing the suitability of the sites, City officers took in to account visibility, the potential to affect sight lines or distract drivers, the potential to obstruct pedestrians, proximity to the first billboard, site works needed and land ownership.
The providers of the first billboard estimated it would cost $16,500 for a new freestanding illuminated billboard, $22,500 for a rooftop one and $27,500 for one that was wall-based.
The first billboard cost $30,361 including printing the canvas, signage and traffic management during installation. Annually, it costs $15,200 including commission fees, banner printing and changeover costs.
The annual costs for the second billboard is estimated at $8600 because it would not include the commission fees.
The Joondalup police station and courts site is owned by the Department of Lands so council approval is subject to negotiations with the department.
A billboard could be installed on the lawn or wall facing Grand Boulevard or on part of the roof.
Councillors at a recent meeting also noted $30,000 has been listed in the 2015-16 budget for the second billboard.
