1. PER NCDENR STORMWATER BMP MANUAL, 'WHEN A WET DETENTION POND IS TO BE LOCATED IN HIGHLY PERMEABLE SOILS LIKE GRAVELLY SANDS OR FRACTURED BEDROCK,
OR WHEN THE PERMANENT POOL ELEVATION PROPOSED IS GREATER THAN SIX (6) INCHES ABOVE THE SHWT, THEN A LINER MAY BE NECESSARY TO SUSTAIN A PERMANENT
POOL OF WATER. A LINER SHOULD BE CONSTRUCTED OR COMPACTED SUCH THAT THE INFILTRATION RATE IS NO MORE THAN 0.01 IN/HR." BASED ON THE NATURE OF THE
SOILS PRESENT ON SITE AS DESCRIBED IN THE SUMMARY REPORT OF GEOTECHNICAL SUBSURFACE EXPLORATION AND ENGINEERING EVALUATION, PREPARED BY EAGLE
ENGINEERING, INC. AND DATED AUGUST 03, 2016 EEI IS RECOMMENDING A GEOSYNTHIC CLAY LINER (SEE DETAIL HERE ON).
2. ENGINEER OF RECORD MUSTPROVIDE WRITTEN CERTIFICATION THAT HE INSPECTED THE FACILITY DURING CONSTRUCTION, THAT THE BMP WAS BUILTACCORDING TO THE
APPROVED PLANS, AND THAT THE SYSTEM COMPLIES WITH THE REQUIREMENTS OF THE RULES.
