TABLE REVIEW:
PLAT PROCESS:
1. ADD THE UTILITIES PROJECT NUMBER DESIGNATED FOR THIS
PROJECT (17-0076) TO ALL PLAN SHEETS.
2. THE WOOLRIDGE ROAD EXTENSION PHASE 3 PLAN (16-0067)
SHOWS A 4" BO AT THE END OF THE 12" WATERLINE IN BOTH
PLAN AND PROFILE HOWEVER SHEET C4.0 OF THIS PLAN SHOWS
REMOVAL OF THE EXISTING 2" BO; PLEASE CORRECT. NOTE THE
PROFILE ON SHEET C5.0 CORRECTLY SHOWS A 4" BO.
3. ADD A 1" ARV AT APPROXIMATELY STA 87+50. PROVIDE
AN APPROPRIATE 12" WATERLINE DEPTH FROM FINISHED GRADE TO
TOP OF PIPE AT STA 102+24 IN ORDER TO INSTALL A 1" TAP FOR
THE ARV. AS THE ARV LOCATION SHOULD BE OFFSET TO A POINT
OUTSIDE THE PAVEMENT (BEHIND THE SIDEWALK), THE COPPER
SERVICE LINE FROM THE 1" TAP SHOULD MAINTAIN A POSITIVE
SLOPE FROM THE CORPORATION STOP TO THE ARV DEVICE. LOCATE
THE ARV BOX 3' BEHIND THE SIDEWALK PER DETAIL WAT-1
WITH THE TOP OF THE BOX INSTALLED FLUSH WITH GRADE.
4. THE SPECIFICATIONS REQUIRE THAT MAINLINE VALVES BE
INSTALLED AT INTERVALS NOT TO EXCEED 1000'; PLEASE PROVIDE
ADDITIONAL 12" GV'S WHERE NECESSARY. UTILITIES PREFERS THAT
MAINLINE GV'S BE INSTALLED ADJACENT TO FH TEES WHERE
POSSIBLE FOR EASE OF LOCATION AND MAINTENANCE.
5. PLEASE INSTALL 8" CLASS 52 RESTRAINED JOINT DI PIPE WITHI
THE INTERSECTION OF INTERSECTION 3 SIMILAR TO THE BAY CREEK
ROAD/ASHTON OAKS TRAIL INTERSECTION.
6. REMOVE DETAIL WAT-16 FROM THE PLAN AND ADD WAT-4.

INTERSECTION OF ASHTON OAKS TRAIL SHOULD BE SUBMITTED AS
SOON AS POSSIBLE AS THIS EASEMENT SHOULD BE DEDICATED
PRIOR TO UTILITIES RELEASING THIS PROJECT TO CONSTRUCTION.
PLEASE CONTACT KIM PULLEY AT 804-748-1376.
THE OWNER IS REQUIRED TO ENTER INTO A COUNTY
