RAIN GARDENS ARE A VALUABLE RESOURCE, AS DISCHARGE PERFORMANCE CAN BE ACCURATELY PREDICTED TO ACHIEVE LLFA COMPLIANCE
Similar calculations are available for alternative features.
Most Lead Local Flood Authorities
(LLFA) have helpful guidance for reference. For example, one LLFA recommends that 12-15% of the total land area be allocated for open storage. This level of land allocation means that it can be challenging to provide suitable
private garden space as well as roads, footways, and other public spaces. An alternative way which minimises land take is to use ‘multipurpose’ SuDS features such as tree pit systems. While these systems may hold relatively less water by volume than an open basin, they can be integrated into a street scene without losing land. Often new
developments have minimum set canopy cover targets, so by using trees as part of a SuDs train, we can achieve two of the targets within the same footprint. Rain gardens are a valuable resource, as discharge performance can be accurately predicted to achieve LLFA compliance. We have invested heavily in soil science and are able to recommend the correct soil mix for the catchment area and rainfall event being designed for. With the latest products available on the market, it is possible to design healthy urban spaces in harmony with nature, and make developments not only sustainable but fi nancially viable.

Loft Lid Downlight Cover from Loft Leg
The Loft Lid downlight cover eliminates heat loss and air leakage into the loft space.
It creates an air tight seal around downlights and allows a continuous layer of insulation to be safely laid over the top to comply with current building regulations.
The Loft Lid is designed and manufactured in the UK and has been tested to EN60695 and
EN60598 by the UK Lighting Industry Association. Please visit the Loft Leg website for more information.
