2. GROUNDWATER WAS ENCOUNTERED IN TEST EXCAVATIONS ON THIS SITE. IF GROUNDWATER IS ENCOUNTERED HIGHER THAN INDICATED ON THE PLANS,
THE CONTRACTOR SHALL NOTIFY THE ENGINEER IMMEDIATELY FOR REDESIGN TO PROVIDE 3' MINIMUM CLEARANCE BETWEEN GROUNDWATER AND THE
BOTTOM OF THE DRAINAGE FACILITY. UNTIMELY NOTIFICATION OF THE ENGINEER MAY RESULT IN ADDITIONAL COSTS TO THE CONTRACTOR. REFER TO
GEOTECHNICAL ENGINEERING REPORT BY SITE CONSULTING, LLC, DATED 06/04/2014 AND UPDATED GROUNDWATER MONITORING REPORT DATED
10/28/2019.
3. ALL MONITOR WELLS SHALL HAVE A CONCRETE APRON POURED AROUND THE CAP.
4. CONTRACTOR TO HAVE PERCOLATION TEST PERFORMED BY SOILS ENGINEER AFTER POND IS FULLY EXCAVATED. CONTRACTOR WILL NEED TO BLAST
(OR BORE) TO CREATE CONDUIT FOR DRAINAGE TO OCCUR. THIS BLASTING (OR BORING) WILL BE REQUIRED TO ACHIEVE DESIGN INFILTRATION OF 5
IN/HR. IF THE PERCOLATION IS LESS THAN SPECIFIED BY THE SOILS REPORT AND ENGINEER (5"/HOUR) REDESIGN OF THE SYSTEM WILL BE
REQUIRED.
