Dear all,
In our project we are planning to follow option 1 path 2. Therefor we provide underground-trench systems and a technical ditch on our project site, which gets inserted creatively into the landscape in the course of the final outdoor facilities planning. Is this an accepted solution for achieving this credit even if the approaches and techniques applied just pursue the aim of detaining the rainwater runoff?
Does an evaporation or an infiltration has to take place?
What do you think?
