If there still is intent on pursuing the Holbrook as a site for HFC, I would do the following :

Plan 1 - offer some kind of community facility for residents such as a kids playground, skateboard park. duck pond - this would get people's heads twisted. Play the green card and make sure the ground development is crammed full of environmental initiatives

Plan 2 - get together with a developer and come up with a scheme that featured a hi-density, social housing scheme

So therefore give the planning process a choice 1 vs 2 - an option that would enhance and enrich the community or an option that merely makes it bigger
