collapsible soil distribution and treatment, foundation design, slope stability for cut and fill slopes 10 feet or higher, lateral earth pressure, and location and effects of nuisance water. In some cases these questions would have to be answered, at least in part, during a feasibility stage investigation. Following are general minimum guidelines for this phase of tract development.

Grading Plan

  1. The tract grading plan shall be at a minimum scale of 1" = 40'. Smaller projects shall have a scale suitable to define grading and foundation parameters. All grading plans shall be on a 24" x 36" sheet of 3 mil mylar.
  2. The first sheet of the grading plan shall be wet ink signed and dated by both the tract geotechnical consultants and the civil engineer.
  3. Building setbacks from recognized active faults shall be clearly identified on the grading plan. Special foundation zones shall be shown on the grading plan or identified in the grading notes.
  4. Cut/fill lines shall be shown on the grading plan.
  5. The locations of proposed structures, surface and subsurface drainage facilities, paved surfaces, drywells, etc., shall be clearly shown on the grading plans.

C. GEOTECHNICAL REPORT

  1. The geotechnical report shall consider all applicable and pertinent earth conditions at the site. The relationship of the site to the regional geologic framework shall also be discussed.
  2. The geotechnical report shall, at a minimum, consider and present the following general requirements where applicable:
  3. Geologic map and cross sections shall be prepared in all bedrock areas. The geologic base map should be the final grading plan. The cross sections should be oriented to best demonstrate site geologic structure. If desired an additional larger scale map may be used to illustrate site geology.
