Table 1 <br /> Routine Maintenance Activities for Biotreatment Areas <br /> 3 Inspect inlets for channels, soil exposure or other Monthly, or as needed after storm <br /> evidence of erosion. Clear obstructions and remove events <br /> sediment. <br /> 4 Remove and replace all dead and diseased vegetation. Twice a year <br /> 5 Maintain vegetation and the irrigation system. Prune and Before wet season begins, or as <br /> weed to keep bioretention area neat and orderly in needed <br /> appearance. <br /> 6 Check that mulch is at appropriate depth (3 inches per soil Monthly <br /> specifications) and replenish as necessary before wet <br /> season begins. <br /> 7 Inspect bioretention area and planter box using the Monthly, or after large storm events, <br /> attached inspection checklist. and after removal of accumulated <br /> debris or material <br /> 8 Repair or correct any initial drainage, erosion and Post-construction <br /> inlet/outlet problems. <br /> Regularly water during the first three months as <br /> vegetation establishes roots. <br /> 9 Remove and dispose of any pollutants that accumulate Monthly or as needed <br /> (identify and control pollutant source). <br /> 10 Remove debris and sediment from inlets and outlets Semi-annually <br /> to avoid clogging. (beginning and end of rainy season) <br /> 11 Re-grade or replace soil surface if erosion, scourging or Annually <br /> significant setting has occurred. <br /> Prune vegetation that inhibits line of sight at intersections. <br /> Test and ensure proper irrigation system function and <br /> sprinkler head adjustment (at end of rainy season). <br /> Repair any rodent borrowing damage and eradicate <br /> rodents. <br /> 12 At cleanouts, check for standing water in underdrain Semi-annually <br /> system. (beginning and end of rainy season) <br /> If standing water is observed, have underdrain system <br /> cleared of roots and debris. Capture material cleared from <br /> line. Flush observed sediment from line. Capture flushed <br /> sediment. (Do not flush sediment to Bay.) <br /> 13 Till soil and/or aerate soil if the system does not drain As-needed <br /> within the designed drain time. (Shallow tilling/aeration) (expected to be 3 to 5 years) <br /> Snake u-drain to clear blockages and/or improve drain <br /> time. <br /> 14 Read and record irrigation water meter. Weekly <br /> Note if excess water usage is occurring and correct if <br /> necessary. <br /> Check soil moisture and adjust watering frequency to <br /> maintain proper soil moisture range for expected weather <br /> conditions. <br /> Inspect for faulty sprinklers and drippers and replace <br /> components as needed. <br /> ATTY/AGR.2016.221/Liberty Hall Lane Partners, LP - STMMA - Lot 5 <br />
