Four Labour-run South Wales councils are concerned at plans by their own party to massively expand Cardiff, warning it could worsen traffic and stifle growth.
Caerphilly, Rhondda Cynon Taf, Newport and the Vale of Glamorgan councils have responded to Cardiff council’s consultation on its Local Development Plan Preferred Strategy.
All but RCT backed the need for 45,000 new homes by 2026, including 18,000 houses on greenfields in the city’s north and west, but each had concerns about its impact on their residents.
In its response, Caerphilly said while the borough would benefit from Cardiff’s growth, the release of too much land could affect its own development opportunities.
It said allocating 18,000 new houses for greenfields could undermine the delivery of Caerphilly’s housing targets, particularly in the Caerphilly Basin.
The council suggests Cardiff’s release of undeveloped land for housing be phased to ensure the rate of any new development is spread across the plan period.
“This phasing should identify a limit on the number of units that can be released before certain dates in the plan for each of the strategic sites in order to ensure that not all development takes place at the same time, as this will impact on the capacity of developers to deliver sites elsewhere in south east Wales,” it states.
Caerphilly also dismisses the need for a designated greenbelt north of Cardiff, a proposal championed by Cardiff North AM Julie Morgan.
It says a greenbelt between Cardiff and Caerphilly “would serve little purpose” provided Cardiff includes sufficient environmental protection policies within its LDP.
RCT has worries about the impact 10,250 new homes in north west Cardiff – west of Pentrebane, south of Creigiau and north of Junction 33 of the M4 – would have.
RCT said it was of “significant importance” that any growth in Cardiff “does not prejudice the ability of our residents to access the jobs and services that the city offers”.
It said because of the lack of detailed information on the impact of the new homes it “cannot yet support the Preferred Strategy” and was issuing a “holding objection”.
The Vale of Glamorgan, meanwhile, supports the need for 45,000 houses, but has told Cardiff it is against building 2,000 of these homes at Junction 33.
It believes this would result in more car journeys on the M4 and exacerbate existing congestion at junctions 32, 33, 34 and at Culverhouse Cross.
The council also suggests a need to consider coordinating public transport and direct links into Cardiff from the east of the Vale.
Newport said a greenbelt east of the proposed 2,000 home development between Pontprennau and Old St Mellons was needed to maintain the identity of the two cities.
It also said the ability of the M4 to accommodate more car trips was a major concern and highlighted the need for a new M4 relief road before employment sites in east Cardiff can be supported.
The LDP Preferred Strategy proposes 45,000 new homes are be built in Cardiff up to 2026:
West of Pentrebane – 7,500 homes, with employment and community uses
North of Junction 33, M4 – 2,000 homes, employment and other community uses, plus park and ride
South of Creigiau – 750 homes with associated community uses
West of Pontprennau – 6,000 homes, with employment and other community uses
East of Pontprennau – 2,000 homes with associated community uses
Former Arjo Wiggins Works, Ely – Mixed use scheme, known as The Mill, of about 700 homes, with employment and community uses
Former Grangetown Gas Works, Ferry Road – 500 homes plus community uses
