Below is a list of each comment received, and our <br />response. <br /> <br />Stormwater Drainage Report <br /> <br />Comment: Under Minimum Requirement 2, element 4, it is not recommended to use the permanent media filter <br />stormwater treatment device for erosion control <br /> <br />Response: Text has been added to the erosion control plan sheet C2.09 stating the stormwater treatment <br />device shall be inspected cleaned, and new media installed upon final site stabilization. <br /> <br />Appendix 5, Sheet 02 <br /> <br />Comment: Minimum Requirement 2 mentions a silt fence along the south portion of the site yet none is shown on <br />Sheet 02. <br /> <br />Response: A silt fence along the south portion of the site has been added to the erosion control plan <br />sheet C2.09. <br /> <br />Comment: This sheet should have a north arrow and scale. <br /> <br />Response: A north arrow and scale have been added to Sheet C1.02 (Formerly Sheet 02). <br /> <br />Comment: Please ensure there is adequate hydraulic drop in the Modular Wetlands system (SDCB 4). It appears <br />there is no drop between the inlet and outlet. <br /> <br />Response: The modular wetland has been oversized in order to provide treatment with the low drop. This <br />design has been confirmed by the manufacturer to meet treatment requirements. See attached <br />correspondence with Forterra from March 10, 2022. <br />
