A. All grading shall comply with and be governed by the international building code, as adopted by the state and the city, whether on public or private lands.
B. In addition, the following requirements shall apply:
1. Prior to placement of concrete for the footings of a structure, the owner shall provide a survey prepared by a licensed engineer or land surveyor to verify that the structure is at an elevation which will allow for proper drainage away from the structure and to an approved drainage facility. The survey requirement may be waived by the building official or the city engineer where compliance can be shown without conducting a survey.
2. New streets shall be so arranged as to allow for drainage to be contained in and channeled through the streets in the event the storm drain system fails, or its capacity is exceeded.
3. Slope easements shall be provided for new streets as necessary to assure that failure of slopes or retaining structures will not adversely affect structures on the abutting properties.
4. The accumulation of water from more than two (2) lots along interior lot lines shall not be permitted unless provision is made for the appropriate disposal of accumulated water.
5. A preliminary grading plan shall be submitted with preliminary subdivision plats and preliminary site plans. The grading plan shall show existing topography of the area and proposed grading using a maximum contour interval of two feet (2'). (2001 Code § 89-6-411; amd. 2009 Code)
C. Grading and drainage plans and construction shall be in conformance with the city "Public Improvement Standards, Specifications And Plans Manual". (2001 Code § 87-5-114; amd. 2009 Code)
