11. Can the CMP culverts under the concrete low water crossing be bedded and backfilled with native material or is a specific material required?

Per Geotechnical Report, native material is considered acceptable structural fill based on specifications found therein.

12. Please confirm the scope of the campsites for this project. Sheet C100 shows a total of 15 campsites but the bid schedule only shows a quantity of 5 EA picnic table and fire rings. Will all campsites or just 5 be constructed? If 5, please indicate which 5.

Only 5 campsites will be constructed. They are shown on sheet C200.

13. Please confirm the scope of roadway grading. Sheet C100 shows Route 8002 to the existing non-motorized trail, a loop road, and 2 small roads to primitive campsites to be graded. Sheet C101 only provides a site plan for a portion of route 8002 and route 8002C as the grading scope. Please confirm the limits of roadway grading.

The scope of roadway grading is shown on sheet C300 and C301.

14. Is native material acceptable under the concrete low water crossing or is a specific material required?

Yes

15. There is a pipe rail fence detail in the plans. Where is this scope of work required?

Pipe rail fence is not part of this phase.

16. The project plan erosion control notes indicate that seeding is required. Please provide location of seeding requirements, native seed mixture and a method of payment for this scope of work.

Seeding of disturbed areas outside of the roadway corridor, or areas outside of the established campsite areas shall be revegetated as warranted (Example: laydown yards, equipment turn around points).

17. Please confirm the road compaction quantity. Based upon our preliminary takeoffs we have a different quantity.

Road compaction is for Type 1 Roadway and Type 1 Roadway w/ Pullout shown on Sheet C300. Type 4 Roadway is to be graded to smooth out road surface to establish a maintained finish shown on sheet C301.
