Conditions or Reasons for Planning Application - CB/23/02104/DOC
Conditions or Reasons:
3) No development shall commence until an assessment of the risks posed by any contamination shall have been submitted to and approved in writing by the local planning authority. This assessment must be undertaken by a suitably qualified contaminated land practitioner, in accordance with British Standard BS 10175: Investigation of potentially contaminated sites - Code of Practice and the Environment Agency's Model Procedures for the Management of Land Contamination (CLR 11)
(or equivalent British Standard and Model Procedures if replaced), and shall assess any contamination on the site, whether or not it originates on the site.

Reason: To ensure that any contamination which exists on the site is identified and properly dealt with in the interests of the residential amenity of the future occupiers of the site and of the surrounding area.
(Section 15, NPPF)
5) No development shall commence until a detailed surface water drainage design has been submitted to and approved in writing by the Local Planning Authority. The agreed design shall be fully implemented and subsequently maintained, in accordance with the agreed management and maintenance arrangements. The scheme to be submitted shall include, at a minimum:

Details of the proposed area of hard standing.
Plans and calculations showing sufficient disposal, storage and conveyance of surface water runoff from the proposed development (up to and including for the 1in100 year event + a 40% allowance for climate change).
Results of site-specific infiltration testing to support the use and design of infiltration devices (in accordance with BRE 365), where infiltration is found not to be feasible then a proposal to discharge surface water off site shall not exceed the greenfield rate/volume and shall demonstrate the receiving system is of sufficient capacity and condition to receive flows without increasing flood risk elsewhere.
Details of the layout of the drainage scheme in its entirety and use of sustainable drainage principles.
Details how the proposed dwellings will be made safe from the risk off flooding from existing sources through the use of flood resistant/resilient measures and methods of construction, as they are set out in the document 'Improving the Flood Performance of New Buildings: flood resilient construction (GLG, 2007)'.
Overview of proposed construction of the system and any phasing of works.
Confirmation of the management and maintenance arrangements for the surface water drainage system in its entirety, including any split in public and private responsibilities
6) No development shall commence until details of both hard and soft landscape works have been submitted to and approved in writing by the local planning authority. These details shall include:
i) boundary treatments;
ii) vehicle parking layouts;
iii) other vehicle and pedestrian access and circulation areas;
iv) hard surfacing materials;

These works shall be carried out in accordance with the approved details before any part of the development is first occupied in accordance with the agreed implementation programme.
