Other important validation requirements:
Affordable Housing Requirement:
Application of Policy CP4 (Affordable Housing) – Part (a) and (e) (threerivers.gov.uk)
Energy Statement Requirement:
Policy CP1 of the adopted Core Strategy requires all applications for new residential development of one unit and above and all new commercial development to be accompanied by a CPLAN Energy Statement and Sustainability Checklist to demonstrate the extent to which sustainability principles have been incorporated into the location, design, construction and future use of proposals, and the expected carbon emissions.
The CPLAN Energy Statement and Sustainability Checklist will not be available from 21 March 2016. From this date, applicants will not be able to submit a CPLAN Energy and Sustainability Statement but should submit an Energy Statement demonstrating the extent to which relevant proposals meet the requirements of Policy DM4 of the Development Management Policies document which sets out that developments must produce at least 5% less carbon dioxide emissions than Building Regulations Part L (2013) requirements having regard to feasibility and viability. For building conversions, development proposals must still demonstrate that there would be an overall improvement in the energy performance of the building. Guidance on producing an Energy Statement is available at Guidance on producing an Energy Statement (pdf).
Drainage Strategy Requirement:
The Government has introduced a requirement for all major development proposals to include Sustainable Drainage Systems (SuDS) and details of drainage would be required as a Drainage Strategy. Guidance on requirements and providing Drainage Strategies is available from Hertfordshire County Council as the Lead Local Flood Authority at https://www.hertfordshire.gov.uk/services/recycling-waste-and-environment/water/surface-water-drainage/surface-water-drainage.aspx
