Street Forage

Street Forage would demonstrate the multifunctional nature of green infrastructure. The landscape would handle surface run-off while providing perennial food.

Timber seating modules would made from laminating reclaimed timber sheets and coating each one in a tough lignin resin. These could be made by new carpentry apprentices funded by the Street Forage scheme. 

Some of surface run-off would be used by the plants and duly transpired, while some of it would gradually percolate into the subsoil beneath. This would be achieved by holding the run-off in drains filled with reclaimed aggregate before it is absorbed by the soil.

Street Forage

Multifunctional landscapes deliver multiple benefits

Inspired in part by the High Line and by the Forest Garden of Martin Crawford in Devon, Street Forage would use sites in Deptford to provide perennial food alongside a biodiverse rain garden that holds surface run-off in the hummus of the soil.

The design would consist of a series of modules. Each unit would feature a landscape mound secured with sustainably-sourced coir matting and hazel spars. The plants would then be planted through this into a mixture of manufactured soil and active compost. In the middle of each mound is an entire log. As the log breaks down it would gradually release nitrogen and nutrients while helping to aerate and retain a core temperature.

The planting would be inspired by that found in a forest garden. A mixture of groundcover herbs and dynamic accumulators would help to prevent erosion, harness minerals from the subsoil and create hummus as the large tap roots break down. Other plants such as Autumn Olive would provide a plentiful harvest of tasty berries while also fixing nitrogen into the soil. 

The floor modules could either be constructed from durable hardwood timber or from recycled steel. In a similar way to the High Line's paving units, planting is intended to colonise the larger gaps between the modules  in such a way that it seems to bleed outwards.
