A colleague points me to the website of CLASH [That's the Campaign by Locals Against Sewell Housing, not "the Clash"]
I don't know anything about the local politics of housing in St Albans. But (high) price signals indicated that this is the kind of place where new housing would benefit wider society. Will the New Home Bonus deflect this local opposition? While it might address some of the concerns about congestion, ease the council's funding problems etc, it is hard to see it addressing the fundamental problem - that local people, quite rationally, don't like new development near their homes.
