LATEMPIBUILDINGIHANDOUr [CODESIRETWAL B62- DOC Revised 1107 Page Y of 9 INTRODUCTION Retaining Walls, including shoring structures, are structural systems that provide lateral support for vertical or near -vertical slopes of soil. Several common types of Retaining Walls include: gravity, semigravity, cantilever, soldier pile, sheet pile, proprietary modular block, mechanically stabilized earth, and soil nail retaining walls. The City of Edmonds does not consider rockeries to be Retaining Walls. (See Handout #B63 for specifid- rockery design and permitting information.) DEFINITIONS (See attached Engineering Standard Details E8.11 & E8.12) Wall Height. For permitting purposes, Retaining Wall height is defined as the height measured vertically from the finished grade at the exposed toe of the Retaining Wall to the highest point of the finished wall. Setback Area Height. For setback purposes, Retaining Wall Setback Area Height is defined as the height measured vertically from the original grade to the highest point of the Retaining Wall supporting soil. EXEMPTIONS FROM PERMIT REQUIREMENTS A Retaining Wall permit is not required for the following conditions: • Retaining Walls four (4) feet or less in height, provided that none of the conditions below (numbers 1-5 under General permit requirements) apply. (See Wall Height definition above.) • For Retaining Walls proposed for construction in conjuction with an approved subdivision or short plat, a separate retaining wall permit is not required. However, wall details shall be included on the subdivision/short plat civil drawings, the submittal requirements listed on page 1 of this handout shall be submitted with the plans, and plan approval signed by the City Engineer will constitute Retaining Wall approval. Retaining Walls shall be designed, reviewed and approved based on the requirements of this handout. • Retaining Walls four (4) feet or less in height proposed on an individual lot with a Critical Areas determination of Erosion Hazard Area only. Other Critical Areas determinations do not apply to this exemption. GENERAL PERMIT REQUIREMENTS (See Page 6 for submittal requirements) A Retaining Wall permit shall be required when any of the following conditions apply: 1. Rctaining Walls greater than four (4) feet in heiaht to eight (8) feet in height. (see Wall HeiLht def nition above • Plans must be designed and stamped by a WA State licensed Engineer • Design calculations shall be submitted with the plans, stamped by the Engineer of record • Peer review and special inspection are not required for Retaining Walls S feet or less in height unless a special environmental or potentially hazardous condition exists 2.

Terraced Retaining Walls are subject to the noted conditions above for permit requirements and exemptions; the following conditions also apply: • Each tier is considered to be a separate Retaining Wall (if any individual tier exceeds the threshold for a permit then a permit shall be required for the entire terraced structure) • The upper tier shall be setback from the lower tier a distance equal to, or greater than, the height of the lower Retaining Wall tier. (See Engineering Standard Details E8.12 and E8.12.1 attached.) • If the distance between the upper tier and the lower tier is less than the height of the lower tier then the lower tier shall be considered to support a surcharge from the upper tier and a permit shall be required and be subject to the requirements of this handout L:ITEMP\BU1LD1NG%LkNDOUr 1CODESIRETWA€, B52.DOC Revised t107 Page 3 of 9 GENERAL REQUIREMENTS 1. All Retaining Wall designs that require a permit shall have plans and details stamped and signed by a WA State Licensed Professional Engineer, including the design calculations when required. 2. A soils investigation/report is required to determine the classification of soil design parameters and soil design bearing capacity. All report recommendations shall be incorporated into the Retaining Wall design including drainage considerations. 3. Retaining Walls shall not exceed three (3) feet in height, above original grade, when located in setback areas. (See Setback Area Height definition above.) 4. Retaining Walls of any height shall not be constructed over public utility easements, or be constructed to adversely affect drainage, or create a sight distance hazard. 5. The slope behind the top of a Retaining Wall shall be no steeper than 2:1 (horizontal: vertical) unless specifically approved by the applicant's Geotechnical Engineer. (See Engineering Standard Details E8.11 and E8.12 attached.) 6. Retaining Walls of any height shall not be constructed in, on, or over (developed or undeveloped) City right-of-way, unless specifically approved by the City Engineer. Per ECDC Chapter 18.70 approval of an Encroachment Permit may be granted to locate a Retaining Wall within the City right-of-way if it does not interfere with the public's use of the right-of-way and/or if the proposal benefits the public interest, safety or convenience. (See Handout #E26). 7. A two (2) foot minimum shy distance shall be maintained from Retaining Walls to the edge of roads (including private access roads serving 3 or more lots), streets and alleys. 8. Temporary Spoil. Unless substantiated by the applicant's Geotechnical Engineer, temporary spoil or stockpiling shall be placed no closer than two (2) feet from the surface edge of the excavation, measured from the nearest base of the spoil to the cut. Spoil should be placed so that it channels rainwater and other run-off water away from the excavation. Permanent spoils are considered to be fill and are subject to 113C permitting and fill requirements (a separate fill/grading permit may be required.) GENERAL INSPECTION_ REQUIREMENTS 1. If the Retaining Wall is located on private property and is permitted as part of a building..permit or as a separate Retaining Wall permit, the property owner is responsible to call the City Building inspection line (425-771-0220 ext. 1333) for the following inspections, including but not limited to: Location and Setbacks • Verification of Bearing Soil • Placement of Reinforcement Wall Drainage (behind wall and to a point one foot away from wall) • Drainage dispersal inspection (inspected by City Engineering Division for drainage one foot away from wall to approved dispersal area) • Final Inspection and Height 2. If the Retaining Wallis constructed as part of a- subdivision or short plat site improvenzenthe property owner is responsible to call the City Engineering Inspection line (425-771-0220 ext. 1326) for the noted inspections above.
