Physical planning in Ireland was originally envisaged as a rational decisio
n-making process involving the definition of objectives for the development
of the locally governed area in question, the evaluation of alternative me
thods of furthering growth, choice and monitoring of results. This paper ex
amines the extent to which the process as it has evolved now displays these
characteristics. While the process of making local authority development p
lans is seen to conform to this model of decision-making, the subsequent de
velopment control process, where an individual proposal at a given location
is evaluated, gives cause for concern. The authors note the absence of a r
ational process where a comparative evaluation of a number of sites is unde
rtaken in order to show that the location under consideration is the best a
vailable one for the proposal. The inability of the planning authority or a
ppeals board to assess the project on a full set of environmental criteria
is also highlighted, together with the lack of connectivity between the sta
ges in the development control process and the uneven access of relevant ac
tors to these stages. The Masonite Corporation's application to Leitrim Cou
nty Council for permission to construct a timber manufacturing plant at Dru
msna is used as a case study to highlight the lack of rationality in decisi
on-making within the physical planning process.
