All landscaped areas shall receive topsoil. After subgrade under landscape area has been <br />scarified and brought to 85% maximum dry density, top soil shall be placed evenly to depth <br />of 6" at 85% of maximum dry density. <br />B. Project Inspector must verify that materials are uniformly spread to minimum depth specified. <br />3.12 SLOPE CONSTRUCTION <br />A. Cut slopes shall be constructed to no steeper than 2:1 (horizontal:vertical). Fill slopes shall <br />be constructed to no steeper than 3:1 (horizontal:vertical). Prior to placement of fill on an <br />existing slope the existing slope shall be benched. The benches shall be in a ratio of 1 <br />horizontal to 1 vertical.

Tolerances for finish <br />grades in drainage swales shall be +-0.05'. Tie in new and existing finish grades. Leave all <br />landscaped areas in finish condition for lawn seeding. Landscaped planters shall be graded <br />uniformly from edge of planter to inlets. If sod is used for turf areas the finish grade on <br />which it is placed shall be lowered to allow for sod thickness. <br />B.
