The letter, addressed to Stephen Byers, secretary of state for the DTLR, says there should be greater community involvement in site masterplanning. But the group warns that pursuit of third-party appeals to planning decisions would clog up the planning process.
It said: "This would represent a sledgehammer to crack a nut and would atrophy the development process even further."
The planning process could be sped up, the paper argues, by rooting out poor quality schemes early on. The alliance believes that, if a scheme's land use is consistent with a local plan, it should receive a smooth passage through the planning process.
