Inspect, clean and maintain inlet <br />protection though the course of construction. <br />4.Soil disturbance and grading practices shall be minimized and staged as much as possible. Restoration <br />and stabilization shall be installed in accordance with the SWPPP time requirements or sooner. <br />5.All erosion control practices shown are to be considered the minimum. Additional erosion control <br />practices, measures and materials may be necessary to stabilize sediment within the construction site <br />during during construction. <br />6.Infiltration areas shall be protected during the course of construction to prevent migration of sediment into <br />the infiltration areas. Sediment must removed from the basin bottom and the surface shall the roughed <br />and scarified to achieve the original infiltration rates. <br />7.Surface stabilization and turf shall meet the following standards: <br />Item MnDOT Ref.

Contact Haugo during the <br />course of construction to perform material and compaction testing. <br />9.Clear and grub construction area. Stockpile topsoil for reuse. <br />10.Once the curb and gutter has been installed, place silt fence or and approved equivalent at the back of <br />the curb <br />Infiltration Basin & Testing <br />12.Install erosion control fencing as shown prior to the start of construction. <br />13.Avoid soil compaction of infiltration basin area. Equipment within infiltration basin shall be light weight and <br />tracked. <br />14.The bottom of the infiltration basin shall be scarified to a depth of 12" prior to topsoil and seeding. <br />15.The contractor shall engage a third party material testing consultant to confirm the following: <br />15.1.The infiltration rates meet or exceed the rates for each basin as outlined in the project storm water <br />narrative using a double-ring infiltrometer. <br />15.2.Contact the engineer and owner if any rates do not meet or exceed design parameters. <br />15.3.The frequency of the infiltration tests shall be established by the governing agency. <br />Legend <br />Silt FenceSF <br />Inlet Protection <br />Construction Entrance <br />Erosion Control Blanket <br />Spot Elevation - Proposed <br />Proposed Contour <br />11.94 <br />900 <br />Spot Elevation - Existing(11.94) <br />EOF Emergency Overflow <br />>>Storm Sewer
