The constraint analysis for the 11 factors is presented below. 31 Bells Line of Road Long Term Strategic Corridor Plan Limitations and assumptions The constraint analysis uses the following limitations and assumptions: > The maps show existing conditions within the corridor at a broad scale. > The analysis is based on available data, with limited field investigation. > The analysis covers a large corridor and a vast amount of spatial data. The broad level of the spatial data limits the details available at a local level. Specific limitations within topic areas are discussed in the relevant sections below. It should be noted that any specific programs or projects arising from the plan would be subject to environmental Small lot agricultural land use impact assessment and planning approval processes, where detailed investigations would be carried out, as appropriate. >Open space – recreation >Military 5.2 Land use >Mining The Bells Line of Road corridor contains many important and Moderate constraint varied land uses.

This could create uncertainty for prospective buyers of properties, who could be hesitant to purchase properties due to concern about the potential for future road widening.
