(totally saturated condition). Figure 2-3 provides a table of foundation embedment <br />depths calculated for cohesive soils. Those figures may be used in calculating <br />foundation depths for standard types of signal pole mast arms as a function of soil <br />type and soil strength, and as indicated in the ODOTTraffic Structures,Design Manual. <br />E. Temporary Traffic Control <br />Appropriate temporary traffic control is essential for the protection of workers and the <br />public utilizing the public rights-of-way during construction. Temporary traffic control <br />devices are required to be in place prior to construction activities on or near the public <br />way. These devices are required to be shown on a Traffic Control Plan consistent with the <br />latest editions of the MUTCD, ODOT's Oregon Temporary Traffic Control Handbook and <br />Standard Specifications subject to City review and approval. <br />2.08 WASTEWATER <br />Public wastewater systems shall be designed and constructed in accordance with the City's <br />Wastewater Master Plan, Standard Specifications, Eugene Code Chapters 6 and 7, applicable <br />appendices of this manual, and the following standards. It is also noted that vertical and <br />horizontal separation between wastewater lines and water lines shall be maintained in <br />accordance with DEQ regulations (available at www.deq.state.or.us). <br />A. Analysis (Wastewater Study) <br />A wastewater study shall be prepared for all wastewater systems that include pipe sizes <br />greater than 8 inches or where additional properties may be served by an. extension of <br />the system. The study shall include, but not be limited to, a study map, wastewater flow <br />calculations, and pipe hydraulic calculations. The wastewater study shall be prepared in <br />accordance with standards of this manual and in a manner such that the information is <br />readable when electronically scanned. <br />The wastewater study map shall include, at a minimum, the following: <br />1. Streets and street names. <br />2. Lot lines. <br />3. Contours or other form of ground surface elevation information. <br />4. Proposed and future pipe system, complete with manholes, pipe slopes, manhole <br />flow line elevations, pipe sizes. <br />Public Improvement Design Standards Manual, 2016 Page 2-44 <br />
