The minor amendment for the ESC plan for NGIC has been reviewed. The following comments are
provided.
1. Please provide the date and source of the topography. The contours in this set are noticeably
different than on the approved set. Please provide a signed seal of the surveyor of the latest
contours verifying that the topography as shown is accurate. The new survey should tie in to the
survey from the approved set.
2. The new proposed limits of disturbance should tie into the limits of disturbance of the approved
plans. The amendment should also show approved measures and grading from the previous ESC
plan.
3. Please provide on the plan surveyed zoning boundaries of the parcel (PRD, CO, and RA). No
further disturbance within the area zoned PRD will be allowed. After looking at the County's GIS
data, it appears most of the proposed disturbance is within the PRD boundary.
4. Engineering review maintains a policy that "cleanwater" diversions are not to be used to reduce
the required size of a sediment trap or basin. Please size the settling facility for the watershed
draining to it without the use of diversions. Without the diversions, the expanded limits should be
reduced to just the area around the stockpile and sediment basin/trap.
5. Additional bonding will be required. A bond will be calculated when the plan is approved.
