Detailed Design  9.10 Planting design for SuDS


           The choice of vegetation cover and plant
           species is an important aspect of designing
           SuDS systems and features.  Vegetation is an
           inherent functional part of any soft-landscape
           SuDS feature as well as being about
           aesthetics, usability and wildlife benefits.
           Vegetation type and species selection can
           significantly affect hydraulic and pollution
           control functionality as well as the
           contribution to amenity and biodiversity.

           The SuDS plant palette will often vary from
           conventional landscape design for reasons of
           SuDS functionality, different ground
           conditions and to protect the wider

           environment from chemical contamination.

           9.10.1 Objectives of planting design for SuDS




           SuDS planting design should satisfy general               ■  augmenting biodiversity by structure,
           planting design criteria and relies on an                 species richness and careful management
           awareness of the landscape maintenance                    (refer to the Biodiversity section 9.9)
           requirements. In addition, planting should                ■  creating attractive surroundings and
           fulfill specific SuDS functions, such as:
                                                                     community amenity
              ■  preventing soil erosion
                                                                     ■  protection of the environment by avoiding
              ■  trapping silt and pollution from runoff             the need for herbicides, pesticides or
                                                                     fertilizer treatment.
              ■  encouraging interception (evaporation,
               infiltration and transpiration)

              ■  enabling long term infiltration by opening
               soil profiles through the root growth cycle
