<br /> Included Future surface elevations shall be anticipated as nearly as possible and structure elevations shall be established for future adjustment accordingly
<br /> �tE The County hereby reserves the right to specify In the Special Provisions the gage and surface treatment of any gahtanlzed corrugated metal pipe that
<br /> o be Installed
<br /> F All longitudinal utility facilities are to be established(and dimensioned on sketches)from surveyed centerline of road right-of-way,not from right-o-w
<br /> ordel linesay

<br /> by the Engineer
<br /> C Unless otherwise permitted under the Special Provisions,backfill shall be placed and mechanically compacted In such a manner that the relative
<br /> compaction throughout the entire fill within the County road nght-of-way shall conform to the percentages of compaction as shown on the Trench Detatl
<br /> D Backfill matena]shall be placed In horizontal uniform layers not to exceed in thickness,before compaction,0 67 foot in the bedding region,one foot
<br /> where 90%compaction Is required,and two feet where 80%compaction Is required

<br /> { ) p y ponding or jehing unless a maintenance bond is provided
<br /> F Gravel backfill material shall be utilized only where specr8c2tfy so stated on the face of the permit, it shall be compacted by means of a high frequency
<br /> internal vibrator,the compactor to be of a size and type approved by the Engineer Points of compaction shall be not greater than 18"centers and to the full
<br /> depth of the hR
<br /> G All pavements,curbs,gutters sidewalks,jborrow ditches,pipes,head walls road signs,trees,shrubbery,and/or other permanent road facilities
<br /> impaired by or as a result of construction operations at the construction site(s),or at other ground(s)occupied by materials and/or equipment,shalt be
<br /> restored immediately upon backfilling of the excavation to the original grades and cross sections, and to a condition as good as,or better than existing prior
<br /> to construction
<br /> H All surfacing materials of roadways and driveway approaches cut or damaged by or as a result of construction operations,shall be replaced within
<br /> ONE WEEK following the backfilling of excavation,weather permitting,with compacted layers of surfacing materials at least as thick as the existing,and no
