NOTES:

1. IT IS EXTREMELY IMPORTANT TO MAINTAIN GOOD DRAINAGE THROUGHOUT CONSTRUCTION OF ANY BUILDING.

2. FALL AWAY FROM THE BUILDING SHALL BE 1 IN 20 TO FIRST METER FROM BUILDING EDGE AND 1 IN 50 THEREAFTER,
AS SHOWN SO THAT WATER DOES NOT POND AGAINST OR NEAR THE BUILDING.

3. ALL WATER RUN-OFF SHALL BE DIRECTED AWAY FROM THE BUILDING AT ALL TIMES PRE AND POST CONSTRUCTION.
4. FOR FLAT SITES, AN ENGINEER SHOULD BE CONSULTED TO ENSURE THAT THE FINISHED HEIGHT OF THE BUILDING
ALLOWS PROPER DRAINAGE AWAY FROM THE BUILDING.

5. DRAINAGE MUST NOT DIRECT WATER TO ADJACENT BLOCKS IN A CONCENTRATED STREAM.
