This report concerns the recent inspection we performed of the soil conditions and site topography at the above referenced project Our work was performed at the verbal request of Mr Keith Anderson of Anderson Builders Inc. We understand the site is presently occupied by a two-story residence with a walkout basement and attached garage. We further understand that an addition is proposed for the existing structure. The approximate dimensions of the addition would be on the order of 20' x 30'. In this regard, problems were encountered in obtaining a buildinq permit as the new roof area upsets the ratio of grassed (absorptive area) covered area in the control of surficial runoff As the site is located on Lake Minnetonka, concern has been expressed regarding the increase in the amount of sediments carried into the lake by surficial runoff. Therefore, the purpose of our investigation was to determine the soil conditions existing on the property and to construct a topographic map of the lot area. Then, utilizing the results of our investigation, alternate procedures were to be con- sidered for the control of lot drainage FIELD INVESTIGATION PROCEDURES On March 4, 1975, we performed our investigation of the site. Our investigation con- sisted of construction of a topographic map as well as placing a 29' deep soil boring to aid in determining the subsurface soil conditions Soil Sampling One boring was put down at the location indicated on the attached topographic map, wit,I a 6" power auger and only disturbed samples were recovered Because of this method, our determination of the depth and extent of the various layers of soil and the consistency of cohesive soils are only approximate As the samples were obtained in the field, they were visually and manually classified by the crew chief in accordance with AS1M�D2488-69. Representative portions of all samples were then returned tc the laboratory for further examination and for verification of the field classification. A log of the boring indicating the depth and identification of the various strata, water level inforriat ion and oertinent information regardinq the method of maintaining and advancing the drill holes are attached. Charts -.11ustratinq the soil classification procedure, descriptive terminology and symbols used on the borinq log is also attached AS AMUTUAL PROTECTION TO CLIENTS, THE PUBLIC AND OURSELVES ALL REPORTS ARI SUBMITTSO A, THE CONFIUEN/YAL PROPERTY OF CLIENT..
