The impacts of noise, air and light pollution should be mitigated through the design of the scheme where possible, in accordance with planning conditions. Under the Land Compensation Act 1973 compensation can be claimed if the value of their property is depreciated by noise and other specified physical factors arising from the use of a new or altered highway. The Noise Insulation Regulations 1975 require the council to offer noise insulation or grants to occupiers of dwellings subjected to noise at or above the specified level due to the use of a new or altered highway. The agreement contains a clause requiring the developer to indemnify the council against the full costs of any payments made under these regulations. The council will notify the developer about any claim received and any offers of noise insulation made.
