Inspect bi-annually and after each storm event the contributing drainage areas, Biioretention facility, inlets, outlets, underdrains, overflows and cleanouts for debris, sediment, proper (drainage and damages. Clean and dispose of all debris, trash and sediment properly. Should structural daimages be encountered contact design engineer for replacement information and notify the County of Augusta Engineer of the damages and proposed repair procedures. 2. The observation well shall be checked quarterly and after each large storm event. A log book shall be maintained showing the depth of water in the well during each inspection in ordetr to determine the rate at which the facility dewaters after runoff producing storm events. Once the performance characteristics of the structure have been verified, the monitoring schedule can be reduced to an iannual basis, unless the performance data suggests that a more frequent schedule is required. At the end of the first year the Landowner shall provide a copy of the log book and the revised monitoring schedule to the county engineering department to be reviewed by the Erosion and Sediment control inspector. The inspector will approve the revised monitoring schedule or require further inspections that shall be carried out by the Landowner. 3. Inspect plant material bi-annually. Address any problems found due to disease or insect infestations. Diseased plants must be treated by a qualified professional. Replace any dead ptamt material and prune as necessary. Consult a landscape architect or horticulturist for specific pruning rneasures. All replacement plants shall meet original design specifications. New plants shall be watered everyday for the first t4 days after planting. 4. Conduct organic layer and soil tests twice a year to maintain proper pH. An apphication of alkaline, such as limestone, shall be applied as needed per test results. 5. The soil mix shall he tested annually to check for the presence of toxins and heavyy metals. If levels are high and the plant biologic functions are impaired (dwarfed growth and mortality)) the contaminated soil and any dead plants shall be removed and replaced. All removed material shalll be disposed of properly. In some cases, the removal and disposal of the entire soil base as well as the plant material may be required. Replacement soil mix and plants shall meet original design specifications. 6. Inspect mulch layer for voids and to ensure specified thickness. Replacement of mulch layer is required every two to three years. Mulch shall be replaced in spring. The previous layer shall be removed first. 7. When sand or other street abrasives are used on areas draining to bioretention basinn during snow and icing conditions the pavement shall be power/vacuum swept as soon as freezing weather abates to prevent damage to the basins. 8. Inspect bi-annually all inlets structures, manholes, storm pipes, cleanouts and roof' drains for proper drainage and structural integrity. Should damages be encountered contact design e}ngineer for replacement information and notify County Engineering department of damages and repair procedures. 9. Inspect bi-annually all inlets structures, manholes, storm pipes, cleanouts and roof' drains for debris and sediment. Clean and dispose of all debris, trash and sediment properly.
