The reports include details of the Area Structure Plans (ASP) and Neighbourhood Plans (NP) that have been approved or have been applied for, an estimated number of units in each plan area, an estimated number of units which have been built and the remaining amount of units, and an estimated amount of lots that have been granted subdivision approval. Based on these estimates, Administration is able to calculate land supply estimates, the amount of population growth that could be accommodated by approved ASP and NP plan areas, and how these estimates relate to current water availability estimates.
