Policy
Water should be incorporated into green infrastructure design, for example rain gardens, swales and ponds with pond deck seating.
Policy
Some surface water should be captured for reuse to help with the sustainable management and long-term maintenance of green infrastructure features within the scheme.
Policy
Where included, volumes of water should be split across the site and have wider positive impacts on water management.
Policy
A flood-risk assessment and drainage strategy must be prepared early in the design process and proposals must demonstrate how this has been considered within designs.
Policy
New developments must be able to demonstrate that their resilience under existing and future extreme rainfall events predicted under 2050 climate models.
Policy
Measures to reduce flood risk such as planting more woodland should be explored.
Policy
Street and tree planting should be used as one of the primary means of storm and surface water management and supplemented with more traditional drainage infrastructure where necessary.
Policy
Permeable paving should be used in site designs to slow water runoff.
Policy
Sustainable Drainage Systems (SuDS) must be designed in accordance with the nationally described hierarchy of drainage and the most recent edition of CIRIA SuDS manual and DEFRA’s technical standards on SuDS.
Policy
SuDS must reflect the form and appearance of planted natural watercourses rather than artificial basins.
