GENERAL NOTES
1. ELEVATIONS REFER TO NGVD 1929. ELEVATION BENCHMARK IS THE TOP OF THE EXISTING CAST IRON TANK
COVER IN THE DRIVEWAY. FOR NAVD88 CONVERSION SUBTRACT 1.1 FROM ANY GIVEN ELEVATION. CONTACT
CAPE COD ENGINEERING, INC. FOR ADDITIONAL ELEVATION INFORMATION.
2. PLAN REFERENCE: TOPOGRAPHIC SURVEY PREPARED BY DOWN CAPE ENGINEERING, INC.

SETTING COMPONENTS AND MAKING THE NEW CONNECTIONS. CONTACT CAPE COD ENGINEERING, INC. PRIOR TO
MAKING ANY CHANGES. FROM THE PLAN.
6. A 5 FT. PERIMETER EXCAVATION AROUND AND BELOW THE SAS TO AN APPRXIMATE DEPTH OF 8 FT. IS OPTIONAL
BUT RECOMMENDED SUBJECT TO INSPECTION PRIOR TO RE -FILLING WITH CLEAN SAND. C1 LAYER PERC TESTED;
C2 IS SLIGHTLY CLEANER; C3 IS CLEAN
.7. ALL EXCAVATED SOIL SHALL BE TRUCKED OFF SITE AND SELECT MATERIALS TRUCKED IN TO RE -FILL THE
EXCAVATION AND TO PROVIDE SUITABLE SUBSOILS AND TOP SOIL ABOVE THE SAS.
