Re: retaining wall
� � D IN IVIL ES G PRo � �i. =��� � MEMORANDUM DATE: September 13, 2012 TO: Tom Henjum- Boyer Building Corporation FROM: Michael R. Johnson, P.E. - Civil Design Professionals RE: Kapsner Residence Retaining Wall Analysis (12-296) Orono, MN Tom: I have been asked to analyze and verify whether the botilder wall construction meets minimitm standard safety requirements at the Following residential location: Kapsner Residence 75 Leaf Street Orono, MN 55356 I have been provided both photographs and a survey of as-built consrruction (attached) for use in the analysis of the existing boulder wall construction. Info: There are two set of tiered walls located on the properry that abut the foundation of the home, both on the North and West fotindation walls. North Foundation Boulder Wal1s: Lower Wall Maximum Wall Height: 25' Upper Wall Maximum Wall Height 2.5' Minimum Distance Between Reraining Walls: 5.5' West Foundation Boulder Wal1s: Lower Wa11 Ma�cimum Wall Height: 3.8' Upper Wall MaYimum Wall Height 3.5' Minimum Distance Between Retaining Wal1s: 7.6' The boulder walls have a minimum boulder depth of 20" and a wall Uatter ranging from 10°-15° It is my undersranding that the site soils are primarily a silty sand material. The slopes above, below and in between the two sets of tiered walls are relatively flat. Civil Design Professiona/s • 8609 Lyndale Ave. 5., Suite 200 Bloomington, MN 55420 • Office 612-284-3696 • www.cdp-us.com Conclusions: Each of the boulder walls have adequate size, as the minimum boulder wall depth(�20") is more than adequate for the given site surcharge conditions (no dead load, no live load, or top slope), minimum wall batter(10°), and the maximum wall height(3.8'). A 12" minimum boulder would actually meet minimum safety requirements of: SF sliding= 1.50 SF overturning= 1.50 SF bearing= 2.0 The walls have adequate spacing between them to avoid surcharging the lower wall, creating a global stability issue. The minimum spacing requirement is 2H1, where H1 is the height of the lower wall. The case for an acceptable margin of safery is further strengthened by the fact there is no slopes above, between or below the walls, the soil on the site is good material, and the boulders are oversized relative to the maximum wall heights. Therefore, it is my professional opinion that the boulder retaining walls meet all minimum industry safety factors, and will function properly and safely. These conclusions retained are based on my professional opinion. These opinions are arrived in accordance with accepted engineering practices in this time and location. No other warranty is implied or intended. Should additional information become available, this report may be modified based on the new data. Respectfully, Michael.
