Ultimately, developments in Wales are guided by the Local Development Plan system.
Local Development Plans (LDPs) are how planning authorities determine – based on available evidence – what should be built and where. LDPs aren’t as strict as zoning the United States, so in Wales we do at least end up with some mixed-use, mixed-density developments.
For example, if a part of town or city has an LDP, masterplan and supplementary planning guidance encouraging high density mixed residential and retail, then planning applications for those types of developments are more likely to be approved.
Why? It’s at least partially down to planning’s quasi-judicial role.
That sounds like the quasi-judicial role binds the hands of planning committee members, but that’s not entirely the case – especially when it comes to the details.
