24, 49 THRU 60, ETC.). PLEASE SEE THE ENCLOSED DETAILS. A
FURTHER DISCUSSION IS RECOMMENDED.
.
F) IT APPEARS THE OVERALL TOPOGRAPHY ON MOUNT BLANCO SECTION

.
IF THERE IS NOT A DITCH WITHIN THE EXISTING 16' DRAINAGE
EASEMENT LOCATED ON THE REAR OF LOTS 1 THRU 12, THEN A
PROPOSED DITCH SHOULD BE PROVIDED TO ADDRESS SURFACE
DRAINAGE GOING INTO THE EXISTING LOTS OF MOUNT BLANCO
SECTION 3.
.
G) PLEASE PROVIDE LOT FILLING AND GRADING ON LOTS 47/48 TO
ELIMINATE THE LOW AREA NEAR THE 81 CONTOUR-ELEVATION. IN

FLOODPLAIN, ROAD SAG OR 100-YEAR BACKWATER, ETC. WHICHEVER
IS MOST RESTRICTIVE AT LOTS 53, 55, ETC. REFLECT THE CHANGES

.
31. BASED ON THE ROTUNDA LANE ROAD PROFILE (SHEET C-30), IT
APPEARS THE ROAD WOULD BE SLIGHTLY ELEVATED. PLEASE PROVIDE
A GRASS SWALE ALONG THE PROPERTY LINE BETWEEN LOTS 50/51

SECTION 2 AS FUTURE.
.
B) A PARTIAL INSTALLATION OF THE STORM SEWER PIPE STR. 92
