(A) No land shall be developed or altered and no use shall be permitted that results in surface water runoff causing unreasonable flooding, erosion or deposit of minerals on adjacent properties or waterbodies. Runoff shall be properly channeled into a storm drain, a natural water course or drainageway, a ponding area or other public facility.
(B) The Building Inspector, upon inspection of any site which has created drainage problems or could create problems with proposed new development, may require the owner of the site or contractor to complete a grading plan.
(C) (1) Upon completion of the final grading of a lot for occupancy, the Building Inspector shall require the home builder to perform a survey of the site documenting critical grading elevations including:
(a) Elevation of all lot corners;
(b) Elevations of proposed drainage ways in the lot identified on the as-built grading plan;
(c) Final garage floor elevations;
(d) Final driveway grades;
(e) Emergency overflow elevations as they pertain to lot grading;
(f) Date of final as-built survey;
(2) The as-built survey shall completed a minimum of ten days before the final building inspection to verify final grading prior to issuance of any certificate of occupancy for the building and lot in question.
(3) In the event the final inspection is requested during seasons of the year that do not permit grading operations, the builder shall submit a deposit of $1,000 for the city to hold in trust until such time the final grading and survey of the lot can be completed. In the event that additional work is necessary to grade the lot to the design elevations, the city may use a portion or all of that deposit to correct the final grading after the issuance of the certificate of occupancy.
(D) The owner or contractor of any natural drainage improvement or alteration may be required by the Building Inspector or Planning Commission to obtain recommendations from the Minnesota Department of Natural Resources, the Soil Conservation District, affected Watershed District and/or City Engineer.
(E) On any slope in excess of 12% where in the opinion of the Building Inspector, the natural drainage pattern may be disturbed or altered, the Building Inspector may require the applicant to submit both a grading plan and a soils conservation plan prior to applying for a building permit.
