The reliance on accommodating all of the residential development required to 2021 by allocating land for large developments is unacceptable as it is likely to result in excessive release of green belt land for development, especially with regard to Rayleigh's green belt. At least a percentage of the housing allocation should come from windfall development and intensification, though it is reasonable for the council to seek to limit the over intensification of small sites. Some sensible compromise needs to be arrived at, or there is likely to be an over provision of new housing (just as there was in past years), through the excessive release of green belt land, while the occasional windfall site is inevitably going to become available, and some intensification is bound to occur. It is bad enough having development targets imposed from outside, without the council bending over backwards to create a situation where some over provision of new housing is certain to occur.
