Grading: The cluFF layer and native topsoil shall be retained in an undisturbed state to the maximum extend practicable, Any duff layer or topsoil removed during grading aholl be stockpiled on -site in a designated, controlled area not adjacent to public resourcea and critical areas, The material shall be reapplied to other portions of the site where Feasible, Areas that have be6r cleared and graded shall have the soil moisture holding capacity restored to that of the orf_�lnal undisturbed soil native to the site of the maximum extent practicable. The soil in any area that has been compacted or that has had some or all of the durf layer or unclarlying topsoil removed shall be amended to mitigate for lost moisture-holdingg, capacity. The amendment shall take place Lstween May I and October I. Replaced topsoil shall be a minimum of 8 Inches thick, unless the applicc:nt demonstrates that a different thickness will provide conditions equivalent to the soil moisture holding capacity native to the site. Replaced topsoil shaill have an organic matter content cf between 8 to 13 percent dry weight and a pH suitable For the proposed landscape plants, CLEAN UP Landscape contractor / developer shall be responsible for the removal of construction material and debris on the site followinj installation of plant materials, All debris must be removed to a legal landfill facility.

Prior to final plan inspection for the Significant Tree Retention Plan permittee shall submit an AS -BUILT Significant Tree Retention Plan to the DDES Inspector showing all plan revisions / changes and verlFying that the DDES approved Significant Tree Retention plan (approved at the DDES Engineering Review stage) has been completed per plan requirements. This AS -BUILT plan shall be reviewed and approved by the Site Development 5peciallat / Forester that it conforms to 50-220 and can be recorded.
