The NPPF sets out that a range of different types of infrastructure should be planned for. Priorities for infrastructure provision in different parts of the borough are likely to change over the lifetime of plan, reflecting changing circumstances. Planning conditions and obligations will be used to mitigate adverse impacts of development and to ensure timely and effective investment in infrastructure, facilities and services. Obligations will comply with the tests set out in the Community Infrastructure Levy Regulations 2010 or successor regulations. Where it is not possible or practical to provide infrastructure on site, or where a development is required to contribute towards strategic infrastructure, a financial or in-kind contribution will be sought towards provision. The council will work with its partners, funding bodies, infrastructure providers and developers to secure external public funding and deliver appropriate infrastructure where required, in line with national legislation and policy. The phasing and delivery of infrastructure will be agreed on a case-by-case basis.

It is recognised that there may be site-specific circumstances which mean that the cumulative impact of the contributions required through policy would compromise development viability. In these instances, planning applications will need to be supported by a viability assessment which must be well-evidenced and robust. It should set out and justify the selected methodology and assumptions. The assessment will need to have regard to relevant national planning policy guidance and other relevant endorsed guidance. There is a public interest in the outcomes of decisions that are informed by viability assessments; as such they should be prepared on the basis that they will be made publicly available. Any sensitive information should be highlighted to the council and an appropriate way to release this information will be agreed. Planning obligations will only be sought where they meet the planning tests in the NPPF of being necessary to make the development acceptable in planning terms, directly related to the development, and fairly and reasonably related in scale and kind to the development.

"The policies of this Local Plan have been subject to a viability appraisal to ensure that they will not have an unduly detrimental impact on the delivery of development. The council will prepare additional guidance on when developers are contributed and community use agreements will be sought, and the mechanisms for securing these, including through the use of section 106 agreements. To ensure sites are developed comprehensively and deliver required infrastructure, any section 106 agreements will seek to include a clause to avoid the use of ransom strips between adjacent parcels or sites."

Applications must be supported by a strategy for foul and surface water drainage management and clean water supply. Proposals must minimise impacts on water resources and wastewater infrastructure. Split sites and custom build / self-build sites within larger sites should be built in line with a site wide foul, surface and
