RUNOFF CONTROL <br /> Streambank Erosion Control <br /> Mitigation for Stream bank erosion concerns is required when a project proposes to add a net new <br /> 5,000 square feet or more of impervious surfaces. The areas to be impacted are already 100 percent <br /> impervious and no additional impervious surface will be added. This area is currently mitigated for in <br /> the on-site detention vault. No additional streambank erosion BMPs are required. <br /> Runoff Treatment <br /> BMPs to remove sediments and other pollutants from runoff are required when a project proposes to <br /> add or replace 5,000 square feet or more of pollution generating impervious surfaces. The parking <br /> area and bus wash where the impervious surface will be replaced already has runoff treatment <br /> provided for it from the previous site developments via the oil/water separator and bioswale. The <br /> replaced pavement will drain to the same location as the existing conditions. Additional runoff <br /> treatment will not be required because treatment is already being provided. <br /> Community Transit <br /> Kasch Park Operating Base 4 <br />
