A. General. Fill which is intended for building sites shall be constructed in conformance with the requirements of the latest edition of the UBC, as adopted by the city, and an assignment of allowable soil-bearing pressures will be under the jurisdiction of the Algona building official in accordance with the UBC.

B. Fill Location. Slopes shall be no steeper than is safe for the intended use and shall not be steeper than one and one-half horizontal to one vertical, or as recommended by a soils engineer. Fill sites must be approved by the engineer as suitable locations for the proposed fill.

C. Preparation of Ground. The ground surface for fills over five feet in height shall be prepared by removing vegetation, noncomplying fill, topsoil and other unsuitable materials, scarifying to provide a bond with the new fill, and, where existing slopes are steeper than five horizontal to one vertical, by benching into competent material as determined by the engineer. The bench under the toe of a fill on a slope steeper than five horizontal to one vertical shall be at least 10 feet wide, or as recommended by a soils engineer.

D. Fill Material. Except as permitted by the city, no material other than earth material shall be buried or placed in fills. Placement of other than earth material is regulated by state statutes or federal laws and additional permits may be required.

E. Slope Stability. Fills shall be constructed using earth materials, compaction methods and construction techniques, so that stable fills are created.

F. Setback from Property Lines. The toe or catch point of fill slopes shall be set back from the site boundary line in accordance with the following table, unless a retaining wall is designed by the engineer and construction for the project.

G. Notice of Grading or Filling. The city may cause a notice to be recorded as a public record containing provision which will include the nature and extent of the filling which has occurred on the parcel. (Ord. 810 § 1, 1996).
