The City Council, within 20 days after the filing of the application under this article, shall determine whether or not the application complies in all respects with this article and shall determine what additional safeguards, land use, drainage, fill back, etc., and such different use of the streets, highways and alleys of the City as may better protect the City and the public. The City Council shall fix the amount of the bond provided for in § 34-34, and shall state the same and such other requirements as are needed for the health, safety and welfare of the inhabitants of the City and the general public. If the proposed excavation is approved, the City Council shall authorize the City Clerk to issue a permit, if and when the applicant complies with the requirements.
[Code 1979, § 5.254]
If a permit is authorized pursuant to this article, no actual excavation or other operation shall commence or continue until the permittee shall file with the City Clerk a bond in the amount so set by the City Council, conditioned upon full compliance with this article and conditioned upon full performance of the requirements of the City Council for the health, safety and general welfare of the City and the general public. The bond is to be executed by a corporate surety company or be guaranteed by a first mortgage on real estate of the value double the amount of the bond.
[Code 1979, § 5.255]
The City Council may, among other requirements, demand that any portion of any excavation which is no longer being excavated be filled up to a depth of not more than four feet below the surface of the undisturbed ground around it, and the banks to be graded to a pitch of not more than one foot drop to each four feet of surface. The City Council may set standards for drainage from or around the excavation directly into a natural stream so as to eliminate overloading of public drains, watercourses and storm sewers.
[Code 1979, § 5.256]
Upon the abandonment of the operations in the excavation, the excavation shall be filled and the banks graded as provided in § 34-35 and shall be drained so that no stagnant water stands therein. No bond of any permittee shall be released or discharged until the excavation is so filled, graded and drained.
[Code 1979, § 5.257]
If the owner desires to develop the land into residential property with the excavation as a lake thereon, he may make application therefor to the City Council, who may authorize such permit, provided the permittee grades the banks of the excavation to a pitch of not more than one foot drop to each four feet of surface from the top of the bank to the high water mark, with a pitch from the high water mark into the water to a depth of eight feet below the low water stage, with a drop of not more than one foot to each eight feet of surface. The bond shall not be released or discharged until the grading is completed and the land duly platted.
[Code 1979, § 5.258]
During the continuance of the bond as required in this article, any such excavation of four feet depth or more shall be completely surrounded with a fence or a wall constructed of such material and in such manner and of such heights as will reasonably keep children away from the excavation, and there shall be posted on the fence, not more than 100 feet apart, "no trespassing" signs warning of the dangers of the excavation.
