July 3,2017 <br /> Single-Family Residence <br /> L&A Job No. 17-079 <br /> Page 19 <br /> Surface Drainage <br /> Water should not be allowed to stand in any areas where footings, on-grade slabs, or <br /> pavement is to be consfructed. Finish ground surface should be graded to direct surface <br /> runoff away from adjacent buildings. We recommend the finish ground be sloped at a <br /> gradient of 3 Percent minimum for a distance of at least 10 feet away from adjacent <br /> buildings, except in the areas to be paved. <br /> Cleanouts <br /> Sufficient number of cleanouts at strategic locations should be provided for underground <br /> drain lines. The underground drain lines should be cleaned and maintained periodically <br /> to prevent clogging. <br /> RISK EVALUATION STATEMENT <br /> The subject site is underlain at shallow depth by dense advance outwash deposits. These <br /> deposits are of high shear strength and the site should be quite stable. It is our opinion <br /> that if recommendations in this report are filly implemented and observed during and <br /> following completion of construction, the areas disturbed by construction will be <br /> stabilized and will remain stable, and will not increase the potential for soil movement. <br /> In our opinion, the risk for damages to the proposed development and from the <br /> development to adjacent properties from soil instability should be minimal. <br /> LIMITATIONS <br /> This report has been prepared for the specific application to this project for the exclusive <br /> use by Eagle Country Construction, and its associates, representatives, consultants and <br /> LIU & ASSOCIATES, INC. <br />
