Should the elevation inside the fire dike be higher or lower than the elevation outside the dike? ? ?

But in the fire dike specifications, it is stated that the designed ground level inside the fire dike should be lower than the surface of the fire road outside the dike. How should this be understood? ? ?
The elevation inside the fire dike should be lower than that outside the dike. The previous standard was to be higher than the level outside the dike to facilitate drainage. The current regulations for fire dikes now stipulate that the designed ground level inside the fire dike should be lower than the surface of the fire road outside the dike.
Sir, then how should rainwater be drained from inside to outside of that flood barrier? ? ? How do you actually do it? ? Thank you!
Indeed, how should the elevation of the ground inside and outside the fire dike be determined these days? It seems there are no subsequent regulatory requirements! Is it such that the area inside the fire dike is higher than the area outside it, and the roadbed outside the fire dike is lower than the surface of the fire fighting road? In this case, it can be said that the fire fighting road, the roadbed outside the fire dike, and the ground inside the fire dike form a wavy pattern, with one wave following another!
