<br /> Re: Susan Sumey Shoreline Restoration
<br /> File No. 139-1807
<br /> Dear Jeanne,
<br /> We have inspected the recently constructed shoreline repair on the Sumey property at
<br /> 1330 Cherry Place in Section 8 and found it to be unsatisfactory. The repair was
<br /> constructed with clay fill reinforced with geogrid which was anchored to the existing
<br /> slope with duckbill anchors. The information we had reviewed previously (including the
<br /> plans, all written correspondence and several telephone conversations with the applicant
<br /> and Stephan Spartz of Landview Landscaping) indicated that the fill soil would be a
<br /> granular material. We stated in our letter dated April 6, 1993, that: "The fill soil should
<br /> be a granular material. Clay soil is not recommended for this type of application."
<br /> Granular fill has more structural value when wet conditions prevail. The surface of the
<br /> granular fill could be protected from erosion with a clay layer or a permanent turf
<br /> restoration product.
<br /> The slope reinforcement should not be approved by the City without a geotechnical
<br /> engineering design and approval.
<br /> Please contact me at this office if you have any questions regarding this matter.
<br /> Yours very truly,
<br /> BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC.
