NOTES:
1) THE LOT DRAINAGE IS VERY
SIMILAR TO PRE CONSTRUCTION
CONDITIONS. APPROXIMATELY 75% OF
OF THE LOT ALREADY FLOWS TO THE STREET.
2) 75% OF THE WATER FROM THE PROPOSED GARAGE
ROOF WILL FLOW TO THE STREET AND 25% TO THE
ALLEY. PLEASE SEE THE FLOW BREAKDOWN IN
BOX AT BOTTOM OF PAGE.
3) THE PROPOSED CONCRETE DRIVEWAY WILL
FLOW TO THE ALLEY (299 sf)
4) AN EXISTING CONCRETE SIDEWALK THAT
CONNECTED A PERGOLA TO THE ALLEY WILL BE
REMOVED. THIS REMOVES 114 sf OF IMPERVIOUS
SURFACE FROM THE REAR 1/2 OF THE LOT.
