The institute has called for guidance on expected investment to assess the likely impact of the community infrastructure levy (CIL). Its comments were made in response to DCLG consultation on draft CIL regulations, which closed today.
"The levy is being portrayed as the solution to infrastructure requirements arising from growth," explained RTPI acting director of policy and partnerships Matt Thomson.
"However, it cannot be relied on to do this, especially in current economic circumstances and if, as is suggested, there is a wide range of exemptions or reductions in payments on the basis of viability or charitable status. CIL can only ever be part of the infrastructure solution," he added.
The RTPI maintained that it supports the principles behind CIL but has reservations about some details of the proposals.
"Another concern relates to proposals to scale back section 106 agreements, which effectively make the 'optional' CIL system compulsory," said Thomson.
