The following rehabilitation standards shall apply to the site of any operation permitted under this chapter:
A. Rehabilitation shall be a continuing operation occurring as quickly as possible after the extraction operation has moved sufficiently into another part of the extraction site.
B. All banks and slopes shall be left in accordance with the rehabilitation plan submitted with the permit application.
C. Slopes, graded areas and backfill areas shall be surfaced with adequate topsoil to secure and hold ground cover. Such ground cover shall be tended as necessary until it is self-sustained.
D. All water areas resulting from excavation shall be eliminated upon rehabilitation of the site. In unique instances where the city council has reviewed proposals for water bodies at the time of approval of the overall plan and has determined that such would be appropriate as an open space or recreational amenity in subsequent reuse of the site, water bodies may be permitted.
E. No part of the rehabilitation area which is planned for uses other than open space or agriculture shall be at an elevation lower than the minimum required for connection to a sanitary or storm sewer. (Ord. 375, sec. 1, 5-1-1989)
