Permanent <br /> erosion hazard mitigation strategies include: <br /> a Selecting construction methods that limit addition of impervious surfaces to the site. <br /> o Maintaining vegetative cover or other soil-stabilization cover in unbuilt areas. <br /> • inspecting, maintaining, replacing, and/or modifying as necessary any permanent <br /> stormwater control devices installed as part of the construction. <br /> The mitigation strategies identified above should not be considered complete or exhaustive. <br /> An erosion control plan should be developed and included in project plans and implemented <br /> during construction. <br /> • <br /> • <br /> • <br /> ASSOCIATED EARTH SCIENCES,INC. <br /> May 10,2018 Page 10 <br /> NS/!d-170649E002-2-ProJects`2027O 491KElWP <br />
