The inspection, maintenance, and repair of the system components are the responsibility of the property Owner / Manager. Stormwater System Components • Vegetated Sheet Flow Dispersion - The vegetated dispersion area that. conveys runoff to the infiltration trench is the responsibility of the property Owner / Manager. The vegetated slope should be inspected at least semi-annually and preferably after a large rain event. Sediment accumulation and any debris / t,fash should be removed to ensure adequate conveyance of runoff. Sparse or bare vegetation should be repaired / replanted with a seed mixture as indicated in the approved plans. Eroded or scoured portions of the slope should be filled, regraded and seeded per the approved plans. • Infiltration Trench - Runoff from the private parking areas is conveyed to the infiltration trench from the vegetated dispersion area. Like the vegetated dispersion area, the infiltration trench is the responsibility of the property Owner I Manager. The trench should be inspected at least annually and preferably after a large rain event. if standing water is observed and it appears that the infiltration trench is not draining properly it is recommended that the Owner I Manager seek assistance from someone experienced with this type of investigation (Public Works, contractor, engineer). inspection Tasks and Schedule These components should be inspected at least annually, preferably after a major rain event. Inspections shall use this report as well as the criteria from the Stormwater Management Manual for Eastern Washington (SWMMEW), as necessary. Contact the local public works department or the project engineer for assistance. Each of the above -listed components should be checked and a written record of the inspections sl7a# be kept by the Property Ownef / Manager.

The inspection, maintenance, and repair of the system components are the responsibility of the property Owner / Manager. Stormwater System Components • Biofiltrafion Swale - The grass lined biofiltration swale that conveys runoff to the infiltration trench is the responsibility of the property Owner / Manager. The grass lined swale should be inspected at least semi-annually and preferably after a large rain event. Sediment accumulation and any debris / trash should be removed to ensure adequate conveyance of runoff. Sparse or bare vegetation should be repaired / replanted with a seed mixture as indicated in the approved plans. Eroded or scoured portions of the swale should be filled, regraded and seeded per the approved plans. Vegetation within the swale should be maintained to a height of 34" and any nuisance weeds should be removed, Note: Do NOT flush the swale and wash the sediment downstream. Doing so will wash the sediment into, and potentially contaminate, the infiltration trench. Remove the sediment with a shovel. There is no need to be overly meticulous as the intent is to simply provide volume for additional sediment to collect in subsequent storms. • Infiltration Trench - Runoff from the private parking areas is conveyed to the infiltration trench from the biofiltration swale. Like the swale, the infiltration trench is the responsibility of the property Owner / Manager. The trench should be inspected at least annually and preferably after a large rain event. If standing water is observed and it appears that the infiltration trench is not draining properly it is recommended that the Owner I Manager seek assistance from someone experienced with this type of investigation (Public Works, contractor, engineer).
