A. Soils:
1. Fill areas shall be prepared by removing organic material such as vegetation and rubbish, and any other material which is determined by the soils engineer to be detrimental to proper compaction or otherwise not conducive to stability. No rock or similar irreducible material with a maximum dimension greater than eight inches (8") shall be used as fill material in fills that are intended to provide structural strength.
2. Fills shall be compacted to at least ninety five percent (95%) of maximum density, as determined by AASHTO T99 and ASTM D698.
3. Cut slopes shall be no steeper than two (2) horizontal to one vertical. Subsurface drainage shall be provided as necessary for stability.
4. Fill slopes shall be no steeper than two (2) horizontal to one vertical and shall not be located on natural slopes two to one (2:1) or steeper, or where fill slopes toes out within twelve feet (12') horizontally of the top of an existing or planned cut slope.
5. Tops and toes of cut and fill slopes shall be set back from property boundaries a distance of three feet (3') plus one-fifth (1/5) of the height of the cut or fill but need not exceed a horizontal distance of ten feet (10'). Tops and toes of cut and fill slopes shall be set back from structures, including pools and water features, a distance of six feet (6') plus one-fifth (1/5) the height of the cut or fill, but need not exceed ten feet (10').
6. The maximum horizontal distance of disturbed soil surfaces shall not exceed seventy five feet (75').
B. Roadways:
1. Road alignments should follow natural terrain and no unnecessary cuts or fills shall be allowed in order to create additional lots or building sites.
2. One-way streets shall be permitted and encouraged where appropriate for the terrain and where public safety would not be jeopardized. Maximum width shall be seventeen feet (17') between the backs and curbs.
3. The width of the graded section shall extend three feet (3') beyond the curb back or edge of pavement on both the cut and fill sides of the roadway. If sidewalk is to be installed parallel to the roadway, the graded section shall be increased by the width of the sidewalk plus one foot (1') beyond the curb back.
4. Standard six inch (6") vertical curb and gutter shall be installed along both sides of all paved roadways.
C. Driveways And Parkings: Combinations of collective private driveways, cluster parking areas and on street parallel parking bays shall be used to attempt to optimize the objectives of minimum soil disturbance, minimum impervious cover, excellence of design and aesthetic sensitivity.
