Any retaining wall exceeding eight feet in height or varying from the prescriptive design requires an engineered design. Location of Retaining Wall Retaining walls must only be placed against stable slopes, consisting of firm, undisturbed soil. Drainage must be provided as shown with a 4" perforated drain pipe or 2" weep holes spaced not less than 12 feet on center. No surcharge load, such as a building or driveway, may be placed on the retaining wall or within a distance equal to the vertical height of the retaining wall unless an engineered design is prepared for the additional load. Ground Surface Above Retaining Wall The ground surface above the retaining wall shall be less than or equal to 1:1 (i.e. 1-foot vertical to 1-foot horizontal). Retaining Wall Placement The top of the footing for the retaining wall must be set a minimum of 12 inches below grade. The footing and wall dimensions shall not be less than outlined in the retaining wall chart. The footing shall be placed on firm, undisturbed earth. Drainage A minimum of 12 inches of washed granular drainage material shall be placed between the undisturbed soil and the retaining wall. The drainage materials must be composed of gravel with 1-inch particle sizes. Two-inch weep holes shall be located approximately 6-inches above grade, below the granular drainage material, spaced not less than 12-feet on center. At the base of the wall, a perforated drain pipe, with at least a four-inch diameter, shall be installed within the drainage materials. The drain pipe must drain to a point of discharge, approved by Mason County. Inspections Prior to the placement of concrete, the builder must schedule an inspection of the formwork and reinforcement placement for the retaining wall footing. During the first inspection, the inspector will verify the soil condition, footing dimensions, footing reinforcement, and footing placement as well as the provisions for drainage. At the next inspection, the inspector shall verify the wall dimensions and reinforcement prior to the wall pour. A final inspection must be performed once all work is complete.

Gmund level ' A Min.4"diameter perforated drain �r the to an approved discharge. Permits Required A building permit is require for all uplansrockeries over four feet in height. Rockeries less than four feet in height do not require a permit unless: 1) Located on a site containing an Environmentally Critical Area(See Mason County Critical Area Ordinance. 2)There is a surcharge such as a driveway, building footing,etc, 3)impoundment of Class I, II,or III-A liquids (IBC 105.2) OR #4) Possible failure that could cause damage to adjoining properties or structures. Even when rockeries do not require a permit,rockery installers are advised to follow the rockery design principles outlined in this publication. Permit applications for rockeries must include a site plan showing the location of the rockery and a cross section of the rockery showing the proposed design details. Rockery designs must either be prepared by a Washington State licensed engineer or comply with the Prescriptive Rockery Installation Design. Rockeries over 6-feet in height must be designed by a Washington State licensed engineer or architect to ensure stability against overturning,sliding,excessive foundation pressure and water uplift. Upland rockery retaining walls shall be designed for a safety factor of 1.5 against lateral sliding and overturning IBC 1806. Prescriptive Rockery Installation Design DESIGN STANDARDS Do NOT APPLY To SHORELINE EROSION CONTROL BULKHEADS Height:Maximum Six Feet Rockeries installed in accordance with the prescriptive installation design standards described here and reflected in the diagram need not be designed by an engineer unless the Mason County Building Dept. determines special conditions exist. Any rockery exceeding six feet in height or varying from the prescriptive design requires an engineered design. Location of Rockery Rockeries must only be placed against stable slopes, consisting of firm, undisturbed soil. The face of the slope needs to be able to support the rockery. Drainage must be provided as shown. Rockeries must not be placed against fill. No surcharge load, such as a building or driveway, may be placed on the rockery or within a distance equal to the vertical height of the rockery. Ground Surface Above Rockery The ground surface above the rockery should be relatively level. A maximum three foot rise over eight feet from the rockery surface is allowed for the slope above the rockery. After installation of the rockery, the ground surface above the rockery should be finished with an impervious material, such as asphalt, starting at the top of the rockery and extending at least far enough back to cover the drainage material plus one foot of the stable, supporting slope. Angle of the Rockery Face The face of the rockery shall be at least 15 degrees from the vertical. Maximum slope of the face of the rockery is one horizontal to four vertical. Rock Sizes For a rockery between four and six feet in height, the prescriptive standards requires that the lower half be constructed of four-man or larger rocks (defined below). For the upper half, progressively smaller rocks may be used in the installation. ROCK SIZE DESCRIPTION Rock Size Rock Weight Average Dimension 1-man 50-200 lbs. 12"-18" 2-man 200-700 lbs. 18"-28" 3-man 700-2,000 lbs. 28"-36" 4-man 2,000-4,000 lbs. 36"-48" 5-man 4,000-6,000 lbs. 48"-54" 6-man 6,000-8,000 lbs. 54"-60" Rock Placement The base course of rocks must be embedded into firm undisturbed earth to a minimum depth of 12 inches to provide a secure footing for the rockery. The long dimension of the rocks must extend into the slope behind the rockery to provide maximum stability. Subsequent courses of rocks must be placed to lock into the rocks in the lower course or tier. Drainage A minimum of 12 inches of washed granular drainage material shall be placed between the undisturbed soil and the rockery. The drainage materials must be composed of gravel with particle sizes ranging from 1-1/2 inch to 3/8 inch. At the base of the rockery, a perforated drain tile, with at least a four-inch diameter, shall be installed within the drainage materials. The drain tile must drain to a point of discharge, approved by Mason County. Inspections The rockery installer must schedule an inspection prior to placement of the base course so the Mason County Inspector may verify the rockery height, soil condition, rock size, and provisions for drainage, A final inspection is also required once all work is complete. To schedule an inspection call the Mason County 24-hour recorded inspection request line at (360)427-7262. Inspections can also be requested online at: www.co.mason.wa.us or by fax at (360)427-7798.
