Fills which are intended for building sites shall be constructed in conformance with the requirements of the latest edition of the International Building Code (IBC), as adopted by the City of Lakewood, and an assignment of allowable soil-bearing pressures will be determined under the jurisdiction of the City Building Official in accordance with the latest edition of the IBC.

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

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.

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

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 constructed for the project:
