Brooke,
See below the answer to the quest¡ons you needed for the minor grading permit. lf you are fine with the maps and
answers below can you give me a call and I give you me credit card info. To pay the 5100?
L. What is our grading plan? There is no grading plan, we are not changing the existing grade. We will excavate to
expose our pipeline and will backfill and compact back to original grade.
2. What willthe backfill be like? Backfillwill be in6"-I2" layers with mechanicalcompaction in between layers.
Backfill material will be original native material excavated.
3. What drainage plans do we have? Due to size and scope no drainage plan is designed, excavation activities will
use industry best practices with regard to silt fence/straw swaddles to prevent erosion and dispersion offsite.
4. Add anything you can that's pertinent and easily added We are excavating our 30" pipeline for ma¡ntenance
activities. We intend to expose a 20' section of the line, perform non destructive testing to verify wall integrity,
and will backfillthe excavation upon completion. Duration expected 1-2 weeks.
Thanks,
Craig
