- THE PROJECT DOES NOT CONTAIN ANY HIGH POLLUTANT LOADING AREAS (HPLA) AND SECREGATION OR PRE-TREATMENT OF RUNOFF IS NOT REQUIRED.
- THE STORMWATER BASIN AND RECHARGE SYSTEM HAS BEEN DESIGNED TO MAINTAIN A MINIMUM SEPARATION OF AT LEAST TWO (2) FEET FROM THE BASIN BOTTOM TO THE SEASONAL HIGH WATER TABLE.
- THE SOIL PERMEABILITY BELOW THE BASIN DOES NOT PERMEATED IN EXCESS OF 20 INCHES PER HOUR AND NO BIORETENTION SYSTEM IS REQUIRED. UNSUITABLE SOILS MUST BE REMOVED AND REPLACED.
- A GROUNDWATER MOUNDING ANALYSIS INDICATES NO ADVERSE IMPACT TO ADJACENT WATERBODIES, WETLANDS, STRUCTURES OR SEPTICS.
- CARE MUST BE TAKEN DURING CONSTRUCTION TO MINIMIZE COMPACTION OF THE BASIN BOTTOM. THE BASIN AREA MUST BE RENOVATED AND TILLED AFTER CONSTRUCTION IS COMPLETED AND THE DRAINAGE AREA IS STABILIZED. NO EARTHWORK MAY BE PERFORMED WHEN SOIL MOISTURE CONTENT IS ABOVE THE LOWER PLASTIC LIMIT.
