Page 2 of 7 <br />F. When possible, all slopes must be graded in such a fashion so that tracking <br />marks made from heavy equipment are perpendicular to the slope in accordance <br />with standard detail ERO-10. <br />G. All areas disturbed during construction must be restored as detailed in these <br />requirements. The type of permanent restoration shall be clearly shown on the <br />plans including but not limited to sod, seed, impervious cover and structures. <br />Areas in which the top soil has been placed and finish graded or areas that have <br />been disturbed and other grading or site building construction operations are not <br />actively underway must be temporary or permanently restored as set forth in the <br />following requirements: <br />a. Areas with slopes that area less than 3:1 must be seeded and mulched <br />within 14 days of the area not being actively worked. <br />b. Areas with slopes that area greater or equal to 3:1 must be seeded and <br />erosion control blanket placed in accordance with standard detail ERO-2 <br />within 7 days of the area not being actively worked. <br />c. All seeded area must be either mulched and disc anchored, hydro- <br />mulched, or covered by erosion control blanket to reduced erosion and <br />protect the seed. Temporary or permanent mulch must be disc anchored <br />and applied at a uniform rate of 2 tons per acre and have 90% coverage. <br />d. If the disturbed area will be re-disturbed within a six month period, <br />temporary vegetative cover shall be required consisting of an approved <br />seed mixture and application rate. <br />e. If the disturbed area will not be re-disturbed within a six month period, <br />permanent vegetative cover shall be required consisting of an approved <br />seed mixture and application rate. <br />f. All areas that will not have maintenance done such as mowing as part of <br />the final design shall be permanently restored using an approved seed <br />mixture and application rate. <br />g. Restoration of disturbed wetland areas shall be accomplished using an <br />approved seed mixture and application rate. <br />H. All erosion control measures must be maintained for the duration of the project <br />until final stabilization has been achieved in accordance to Part 7. If <br />construction operations or natural events damage or interfere with any erosion <br />control measures, they shall be restored to serve their intended function. <br />I. Additional erosion control measures shall be added as necessary to effectively <br />protect the natural resources of the City. The temporary and permanent erosion <br />control plans shall be revised as needed based on current site conditions and to <br />comply with all applicable requirements. <br /> <br />2. Sediment Control Practices <br />A. Sediment control practices must be established on all down gradient perimeters <br />before any upgradient land disturbing activities begin. These practices must <br />remain in place until final stabilization has been achieved in accordance with <br />Part 7.
