The wall design stipulates that a geotechnical engineer shall be consulted to confirm the soil design assumption the designer made. We should get a copy for the geotechnical report for the file as part for the as built submission. 2. The erosion control should be adjusted to accommodate the additional work. Roger- Note the 8ft retaining wall requires Geo-synthetic reinforcement. Your inspectors should confirm its presence during construction.

This revised design is based on a wall layout plan provided by you dated March 15, 2018. The attached typical section(s) should be referenced for construction details. Special note should be made of the wall embedment depth and the geosynthetic fabric (geogrid) length as measured from the front face of the wall if applicable. Refer to industry standard practice references for installation information, specifications, and details. - Stones shall be placed to avoid continuous joint planes in vertical directions. - Each stone shall bear on two or more rocks below it with good flat-to-flat contact. - Compact any structural fill place behind the drainage zone to 95% standard proctor. - Install woven landscape fabric behind the stone to limit soil migration through the wall face. - Optional drainage stone shall consist of clean 3/4"to 1.5"crushed stone The design of the wall system is specific to the following parameters: • Location: South side of structure at shoreline with a similar single-wall configuration to the existing wall on the south side of the structure. • Exposed height: 8 feet max. total height • Minimum embedment depth = 12", or as noted • Soil conditions: Silt/Clay, friction angle =28.0 degrees, unit weight of 125.0 Ib/ft3 • Allowable soil bearing capacity=2,000 psf • Surcharge loads behind the wall: None • Slope at top of wall: 10:1 • Slope at bottom of lower wall: 2:1 • Boulder sizes: Granite rectangular boulders (10"H, 18"W, 24"D, typical minimum dimensions) • Geosynthetic Reinforcement Fabric Type: Mirafi 3XT or equivalent • Drainage pipe: Required LICENSED PROFESSIONAL ENGINEERS HOME&BUILDING INSPECTIONS J STRUCTURAL EVALUATIONS J / ASSOCIATION RESERVE/TRANSITION STUDIES RESIDENTIAUCOMMERCIAL RETAINING WALL DESIGN&EVALUATIONS 1,, 1700 Bohns Point Road, Orono, Minnesota February 28, 2018 (Rev.
