- to allow decision makers to take into account the cumulative effect of development as a material planning consideration;
- to allow planning authorities an extension of time to adopt a new Core Strategy; and
- to require a sequential test to be applied to encourage the effective use of brown field land.
The promoters of the e-petition would presumably like a LPA to have the ability to refuse (in situations where it has neither a Local Plan or a five year supply of housing), say, the third application on the edge of, say, a market town on the basis that applications one and two bring to capacity, say, the road network or social infrastructure such as schools and doctors.
In 'The Planning System: General Principles' document (2005) it is stated that a proposed development could be refused if it would be so substantial, or where the cumulative effect would be so significant, that granting permission could prejudice an emerging DPD by predetermining decisions about the scale, location or phasing of new development.
In the example above then if application three cannot provide for measures to mitigate it's impact, then the LPA could legitimately refuse it, and hope to be supported by an appeal inspector on the basis that the impact, to be addressed through the development plan, outweighed the need for new homes.
