Box 186 426 W, CEDAR Shelton, WA 98584 Attn: Ms. Debbera Coker, Building Inspector IV Reference: Your letter dated 13 June, 2013; same subject Dear Ms. Coker; Your reference to the IRC is interesting,but that is for a building foundation wall and not a free standing in contact with the soil material that is being retained. I have attached the revelant sections of the International Building Code (IBC) 2012 edition, which refer to Retaining walls and their loads. The 24 inches of unbalanced fill applies to a footing walls and not retaining walls as their purpose to retain earth materials and are not laterally restrained in any way what so ever! This only applies in tall basement walls where the SFR floor structure restrains the top of the footing wall. The builder of the walls should be able to provide as-built plans as I was not retained to provide plans, field survey, or as-built plans for this project. Mr.Marty Reynolds was the builder of the walls and should be able to provide the necessary plans for your files. I do not think that the ground snow load has any bearing of the wall loading,nor does the wind loading have any effect the wall, unless there is a tall extension to the top of the wall. Seismic loading is not a major factor unless there is a major earth quake,that is over 6.0! Otherwise earth retaining walls move with the earth during an earth quake and are not subject to the same stress that a building may experience, and then only a Heavy building i.e. A concrete building(icf). I believe that Mr. Galando was arranging for the Geotechnical report to be prepared. I review the calculations and have made a revision to the 6 foot wall, but it does not change any of the Factors of Safety for overturning, sliding, or bearing! Please note the sections of the IBC which are attached for your information. 1 .

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 West Richland does not consider rockeries(walls constructed of rock from the earth)to be Retaining Walls. DEFINITIONS 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: however retaining walls must also meet the General Requirements listed within this handout: • 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 conjunction 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 A Retaining Wall permit shall be required when any of the following conditions apply: 1. Retaining Walls greater than four (4) feet in height to eight (8) feet in height, (see Wall Height definition 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 8 feet or less in height unless a special environmental or potentially hazardous conditions exists 2. Retaining Walls greater than eight (8) feet in height, (see Wall Height definition 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 required 3. Retaining Walls of any height located in a designated Critical Area other than Erosion Hazard area. • Plans must be designed and stamped by a WA State licensed Engineer and comply with WRMC Chapter???? • Design calculations shall be submitted with the plans, stamped by the Engineer of record • Peer review and special inspection are required for all Retaining Walls located in designated Geologically Hazardous Critical Areas 4. Retaining Walls of any height supporting a surcharge from a street, road, alley, driveway, parking, building, structure or other surcharge or Retaining Walls that impound flammable liquids or hazardous materials. • Plans must be designed and stamped by a WA State licensed Engineer • Design calculations shall be submitted with the plans stamped by the Engineer or record • Peer review and special inspections are required for Retaining Walls grater than 6 feet in height 5. 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. • 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 i RETAINING WALL CONSTRUCTION For gravity block and modular block retaining walls, the contractor shall follow the manufacturer's recommended installation procedure. For all other types of retaining walls, the contractor shall follow the plans and specifications prepared by the Engineer of Record. Keyway The Engineer of Record shall determine the minimum embedment for all walls in accordance with the manufacturer's recommendations or as required by the International Building Code. Wall Backfill For gravity and modular block retaining walls, the backfill material shall be placed in lifts to an elevation approximately six (6) inches below the top of each course of blocks, until the uppermost course is placed. Any backfill material on the bearing surface of one block course shall be removed before setting the next course. For all other types of retaining walls, the contractor shall follow the approved plans and specifications prepared by the Engineer of Record. Backfilling When fill is placed behind a Retaining Wall, the soil parameters for design are based on the knowledge of the proposed fill soils and the anticipated control of the compaction. Special inspection by a licensed geotechnical engineer is required to verify that the soils and compaction procedures are proper and the compacted soils properties achieve the design parameters. Underdrain A minimum six (6) inch diameter rigid perforated or slotted drainpipe shall be placed in a shallow excavated trench located along the backside of the Retaining Wall. The pipe shall be placed on the surrounded by "Gravel Backfill for Drains" to a minimum height of 1'-6" above the bottom of the pipe. A filter fabric shall surround the gravel backfill and shall have a minimum 1'-0" overlap along the top surface of the gravel. This requirement for fabric may be waived by the Engineer of Record if soils and water conditions make it unnecessary. The perforated drainpipe shall be connected to the storm drainage system (other than detention) or an approved outfall. Terraced Retaining Walls Each tier of the terraced Retaining Wall shall be installed in accordance with the prescriptive installation design standards described herein and reflected in the diagrams on the project specific plans and specifications prepared by the Engineer of Record. For gravity block and modular block retaining wall installed in accordance with the prescriptive design standards described herein, the upper Retaining Wall tier shall not be located within a horizontal distance from the lower Retaining Wall tier equal to the height of the lower Retaining Wall. 4 DESIGN CRITERIA FOR RETAINING WALLS General There are two types of Retaining Walls; one type is protecting, typically used for soils that are capable of standing by themselves without support and the other type is retaining or supporting, for soils that are not capable of standing or remaining at the existing slope. Retaining Walls shall be designed based on standard engineering methods provided by the International Building Code (current adopted edition) and WSDOT/APWA Standard specifications for Road, Bridge, and Municipal Construction(current edition). Width and height of footings and walls shall be provided,including a reinforcing steel schedule and design calculations. The submitted plans, specifications, engineering calculations, diagrams soils report, and other data shall conform to the requirements of the current adopted edition of the International Building Code but not be limited to,the requirements of IBC Chapter 1806. Gravity block and modular block walls shall meet the requirements of the City Engineering installation design standards described herein and reflected in the attached diagrams. All other types of Retaining Walls not described within this document shall conform to the requirements of the International Building Code. Wall Backfill For gravity and modular block retaining walls,the Sieve Size Percent Passing 4100 material located directly behind the wall shall conform to Square 2"S 5- 100 US No.4 the manufacturer's recommendations or plans and .4 22 specifications prepared by the Engineer of Record. If there -66 is no manufacturer's recommendation or plans and US No.200 5.0 max specifications prepared by the engineer of record, the wall Dust Ratio: backfill shall consist of well draining granular material in %Passing US No.200 conformance with WSDOT/APWA 9-03.12(2) %Passing US No.40 Sand Equivalent 52 min. Gravel Backfill for Drains A system shall be designed to intercept ground water Sieve Size Percent Passing behind the retaining wall in order to prevent hydrostatic 1" Square 100 pressure on the wall. The intercepted groundwater shall be 3/a" Square 80 100 channeled to an approved drainage system. Specify all 3/8" Square 10 40 drainage materials (piping, type of backfill, etc.) on the drainage plan. Note, the backfill that surrounds the drainage US No-4 0 4 pipe shall conform to WSDOT/APWA 9-03.12(4) outlined in US No. 200 0 2 the adjacent chart. This material shall be placed to a twelve (12")inch minimum width between the entire block facing and the cut slope. J _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 there (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. 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 WRMC Chapter ??? 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. 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 excavating, 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 IBC permitting and fill requirements (a separate fill/grading permit may be required. 9. General Requirements apply even if a retaining wall is exempt from Permitting requirements. 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 (509-967-3518) 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 Engineer for drainage on foot away from wall to approved dispersal area) • Final Inspection and Height 2. If the Retaining Wall is constructed as part of a subdivision or short plat site improvement, the property owner is responsible to call the City Engineer at 509- 967-5434 for the noted inspections above. SPECIAL INSPECTION REQUIREMENTS • For poured concrete Retaining Walls, if the design Engineer specifies a concrete design strength greater than 2500psi, a special inspection is required by either the Engineer of Record or a Special Inspector approved by the Building Official who is certified by the Washington Association of Building Officials (WABO) for reinforced concrete. • The Geotechnical Engineer of record shall verify conformance with the project specific Retaining Wall design including but not limited to: soil bearing conditions and capacity, groundwater conditions, verification of backfill material, compaction methods, drainage, and retaining wall placement procedures, etc. • Field reports by the Geotechnical Engineer of record shall be submitted in a timely manner to the Building Division for review and approval for private individual lot development and to the Engineering Division for subdivision/short plat and right-of- way development.
