32. Finish floor of the building is 19.35’. Septic drainfield piping is above 20.0. A dosing tank/pumps and electric power would need to be included in this configuration vs pre-bid meeting discussion calling out gravity septic system.

Response: See the revised plan sheets attached to this Addendum for gravity septic system design.

33. Gopher tortoises are prolific throughout the park. Are we required to include costs to cover gopher tortoise surveys, or relocation/monitoring?

Wetlands are not identified on the plans. Are we to exclude all Federal, State, County, or City wetland protection requirements?

Response: No wetlands have been identified within the work area.

36. Is silt fencing/erosion control required anywhere along the proposed piping run? (3-4 areas seem to be wetland areas and typically these need to be protected.)

Response: The two treed areas are proposed to be installed via directional drill.

37. Is silt fencing required around the septic/restroom construction areas?

Response: Yes.

38. Directional boring thru the creek area is shown. Another low area closer to the new restroom is full of trees along the piping run. Can the piping run be re-routed further from the road anywhere that large trees are encountered?

Response: Any deviations from the plans should be approved and coordinated prior to construction.

39. The septic drainfield is located inside the dripline of the largest 2 oak trees in the park. Is the septic drainfield location/excavation/backfill going to damage the root system of these trees?

40. Is tree damage/replacement excluded from the job?

Response: There is no expected tree damage as a part of this project. If damages occur, the contractor will be responsible for fixing them as necessary.

41. Is tree protection required in this bid?

Response: No.

42. The large open & level field to the west of the proposed drainfield location is clear of oaks. Is it acceptable to move the drainfield to this area. (see highlighted picture below) It may require removal of 2 palm trees and possibly relocation of a small power pole.

Response: Not at this time. See the revised plan sheets attached to this Addendum for the proposed location of the drainfield.

43. Are soil density tests or concrete tests required?

Response: Sidewalk is considered non-structural and does not require any concrete testing. If the building manufacturer requires a concrete foundation, testing will be required.

44. What is the estimated cost of this project?

48. What is horsepower for pumps on dosing tank?

Response: No dosing tank is proposed in support of this project. See the revised plan sheets attached to this Addendum.
