NOTES

PROPOSED GRADING AND

STORMWATER PROFILES

1. SHEETS CJ101 TO CJ107 SHOW NEW PROPOSED

STORMWATER PIPES AND STRUCTURES, ALONG WITH

ADJACENT EXISTING UTILITIES. ADDITIONAL INFORMATION ON

EXISTING STORMWATER CONNECTIONS TO STRUCTURES AND

OTHER EXISTING PIPES CAN BE SEEN ON SHEETS C-002 TO

C-004.

2. AT LOCATIONS WHERE PROPOSED NEW PIPE CONNECTS TO

EXISTING STRUCTURES, THE FORMER OPENING FROM

EXISTING PIPE TO BE REMOVED SHALL BE BRICK AND

MORTAR SEALED AND NEW PIPE INSTALLED/CORED.

3. EXISTING UNDERGROUND UTILITIES' INVERT AND SIZE

INFORMATION FOR SEWER, COMMUNICATIONS, ELECTRICAL,

WATER, GAS AND STEAM ARE BASED ON ENGINEERING

ASSUMPTIONS AND LIMITED SURVEY INFORMATION. THESE

UTILITIES ARE ASSUMED TO HAVE A NOMINAL 2 FT OF COVER

AT A MINIMUM FOR SEWER, COMMUNICATIONS, ELECTRICAL,

GAS AND STEAM. EXISTING WATER SERVICES ARE ASSUMED

TO HAVE A MINIMUM OF 3 FT OF COVER. CONTRACTOR SHALL

FIELD VERIFY THE LOCATION OF EXISTING UTILITIES AND

INFORM THE VA AND ENGINEERS OF ANY FIELD DEVIATIONS

THAT WOULD COMPROMISE OVERALL DESIGN.

NOTES

1. SHEETS CJ101 TO CJ107 SHOW NEW PROPOSED STORMWATER

PIPES AND STRUCTURES, ALONG WITH ADJACENT EXISTING

UTILITIES. ADDITIONAL INFORMATION ON EXISTING STORMWATER

CONNECTIONS TO STRUCTURES AND OTHER EXISTING PIPES CAN

BE SEEN ON SHEETS C-002 TO C-004.

2. AT LOCATIONS WHERE PROPOSED NEW PIPE CONNECTS TO

EXISTING STRUCTURES, THE FORMER OPENING FROM EXISTING

PIPE TO BE REMOVED SHALL BE BRICK AND MORTAR SEALED AND

NEW PIPE INSTALLED/CORED.

3. EXISTING UNDERGROUND UTILITIES' INVERT AND SIZE INFORMATION

FOR SEWER, COMMUNICATIONS, ELECTRICAL, WATER, GAS AND

STEAM ARE BASED ON ENGINEERING ASSUMPTIONS AND LIMITED

SURVEY INFORMATION. THESE UTILITIES ARE ASSUMED TO HAVE A

NOMINAL 2 FT OF COVER AT A MINIMUM FOR SEWER,

COMMUNICATIONS, ELECTRICAL, GAS AND STEAM. EXISTING WATER

SERVICES ARE ASSUMED TO HAVE A MINIMUM OF 3 FT OF COVER.

CONTRACTOR SHALL FIELD VERIFY THE LOCATION OF EXISTING

UTILITIES AND INFORM THE VA AND ENGINEERS OF ANY FIELD

DEVIATIONS THAT WOULD COMPROMISE OVERALL DESIGN.
