Welcome to 125 Moose Hill Parkway!
 
 
The Math
"A Pints A Pound The World Around!"
 
Developing The Base Figure
Clearly any amount of rain adds thousands of gallons and tons of water,
debris, and road grim which includes oil and rubber to my property.
All water from the intersection of Moose Hill Parkway (MHP) & Upland Road (UR) to 125 MHP -- about mile -- on the 125 MHP side of the road crown is channeled onto my property. The math is simple: Crown to curb is 12 feet X 1320 feet ( mile).
 
Upland Road intersects Moose Hill Parkway after descending from its high point  which is about 3/10 of a mile from the intersection of Moose Hill Parkway & Upland Road. It would be bad enough that the berms of Upland Road fed onto Moose Hill Parkway on the 125MHP side only. It in essence would double that calculation as above, plus add some for the slight difference in total run.
 
BUT, ITS WORSE!
 
THE ROAD IS ROCKED AT THE INTERSECTION OF MOOSE HILL PARKWAY & UPLAND ROAD SO THAT ALL OF UPLAND'S FLOW
RUNS DOWN THE 125 SIDE O MHP
 
 
THIS TRIPLES THE AMOUNT OF RUN-OFF REACHING 125 MHP.
 
And, not even this is all. The Town then created little lips on driveways to keep the water channeled on the road. Now, all of the water from the long driveways of 135 and 145 Moose Hill Parkways is channeled to125 MHP as well.
 
So, let's just figure the square inches (even excluding driveway run-off) to determine the BASE FIGURE to calculate volume / weight for any amount of rain.
 
125 MHP to MHP/UR Intersection:  Crown to curb is 12 ' X 1320' ( mile) or 15,840 sq ft X 144 (sq inches per square foot) = 2,280,960 square inches.
 
MHP Intersection to high point of UR:  24 feet (road rocks dumping full amount onto 125 MHP side) X 1742' (1/3 mile) = 41,808 sq feet X 144 = 6,020,352 sq inches.
 
Total square inches (2,280,960 + 6,020,352) = 8,301,312 square inches of surfaces. Or in a one inch rain storm 8,301,312 CUBIC inches... or, if divided by 1,728 ( which equals the number of cubic inches per cubic foot) 4,804 cubic feet WHICH FAR EXCEEDS THE CAPACITY OF THE BASIN. THAT WOULD STOP THE PHYSICAL RUN-OFF BUT NOT THE WATER / CHEMICAL RUN-OFF.
 
According to my chart, there are 231 cubic inches per gallon OR IN A 1 INCH STORM, 35,936 GALLONS  OF WATER & DEBRIS ACCUMMULATE AT 125 MHP.
 
ONE GALLON OF WATER = 8.337 POUNDS* X 35,936 GALLONS = 299,601 POUNDS of WATER or if divided by 2000 lbs = 149.8 tons!
