4.0 DESIGN AND CONSTRUCTION PROVISIONS <br />4.1 LANDFILL PLANS <br />This section details the elements comprising the proposed landfill <br />site development plans. The plans are based on hydrogeologic, engi- <br />neering, and environmental assessment data used to design the .features <br />needed to comply with the development requirements for a sanitary. <br />landfill. <br />The final grading plan, excavation and preparation plan, fill sequence <br />sections, and details are presented on Drawings 1 through 4. The <br />drawings show the configuration of the completed landfill and con- <br />struction details for the project. <br />4.1.1 Grading Elan <br />The proposed landfill configuration, shown on Drawing 1, is influenced <br />primarily by surrounding topography and maximum landfill heights set <br />by the County. The landfill's maximum fill height will rise approxi- <br />mately 65 feet above the existing ground. <br />A permanent berm will be constructed around the landfill perimeter. <br />This berm defines the limits of the landfill and protects the landfill <br />from contributory surface water (run-on) that might enter the site <br />boundary. The berm is set back 100 feet from the property line to <br />provide a buffer zone. This minimum setback will allow perimeter <br />drainage and monitoring facilities to be constructed. <br />Minimum final landfill slopes of 3 percent will be maintained to pro- <br />vide adequate drainage and prevent ponding after anticipated settle- <br />ment of wastes underlying the upper landfill slopes. Drainage swales <br />will be necessary at three locations to limit final landfill height <br />and maintain minimum landfill slopes. Drainage swales will be <br />PJ9 . .r 0•A rpt 10 <br />
