WR - Should other sites in this location be considered?

What about areas by old brickworks? More space and less congestion along hart road

Only sites with existing industrial usage should be considered for residential development.

To the question "should other sites in this location be considered" - no.
The question that isnt articulated here is "should this location be considered" and the answer is no. Better smaller locations exist which whilst they do not individually equal the desired 550 do contribute to the requirement without the issues incurred with this area.

How about the area south of Rectory Road by the railway station as this would then ease the congestion through Rochford and still provide access to the shops and bus routes. The same area north of Rectory Road could also be used or instead of.
South of Hall Road adjacent to current development through to Cherry Orchard way could be used, this would provide defensible green belt area as well as easing the traffic flow onto Hall Road as alternatives exits from the development could be used.
The area of land south of Tinkers lane and north of Sutton Road. With the new railway station this would provide access to Rochford and also Rail links as well. A new road could be developed to ease congestion from the Anne Boleyn to Sutton Road.
The area south of Sutton road and adjacent to Brook close. With the new railway station this would provide access to Rochford and also Rail links as well.

Could site ref 147 be included on your option WR2?
