STATEMENT OF WORK

Storm repair: fencing, erosion, & trees

Dale Hollow National Fish Hatchery Mar 6, 2025

1. GENERAL/Background: Dale Hollow National Fish Hatchery provides mitigation fish throughout middle Tennessee. The station is looking to manage storm damage trees, creek, erosion, and repair the current fish raceway perimeter fence required to keep out predators and maintain station/visitor safety.

Note: This is a value bid with considerations for selection based on the quality and cost effectiveness task. Please price each SECTION A-D separately as final project decisions may prioritize the tasks based on funds and value return to the USFWS and public.

2. SCOPE:

A. SECTION - FENCE (Replacement captive, live animal security fence damaged by storms) o Fence repair/replacement in sections compromised by wind/rain and no longer able to provide a perimeter pest/predator barrier. Final fence replacement scope may be determined in the bidding phase, please include a cost per linear foot so the station can make repair scope decisions based on funding availability and priorities.

o Station staff demolished the heavily damaged old fence and set up a replacement quick-fix. The repair sections are not finalized with ties/wire and do not completely block animal entry.

o As-needed remove the current chain-link hatchery fence and replace it with new fencing.

• Removal

- Disconnect the hatchery netting from the old fence

- Completely remove all compromised/ineffective poles and fencing around the hatchery fish rearing perimeter

• Re-use (optional)

- If applicable, please include any recommended savings line-item section that includes the component summary of re-usable poles and fence sections (especially on the larger diameter poles that are probably easier to leave in place).

• Replacement

- Trench the hatchery perimeter for replacement fencing

- Install fencing with a minimum of 6” of subgrade buried fence.

Level/grade/compact soil adjacent to the fence to enable easy mowing.

- This low spacing will really help stop critters like otters. Aim to limit gaps to no larger than the chainlink openings.

• Fencing Target Specifications: commercial grade galvanized chainlink fence

(please list material specifications). Above ground fence height: 6’ or more.

Subgrade buried fencing has a target depth of 6-12”. Smarter/better fence recommendation options listed may be considered as part of the bid evaluation process.

Total Fence 2,835 feet

Total gates 5

Double gate sizes One at 10', one at 20', one at 30'

Single gates Two at 6' o Attach & re-attach all net sections to the fence where possible o Fence standards based on ASTM F668, F1712, F2611 and TN best practices

B. SECTION: TREES, STUMPS, & DEBRIS

o FELL TREES

• Trees in the storm route require evaluation with removal as recommended by an arborist

• Fell and remove trees with stump and replacement processing o STUMPS

• Cut & grind stumps to ground level within the storm damage area

• Remove sufficient roots and add topsoil in replanting locations to allow successful replanted tree growth o DEBRIS REMOVAL

• Over 60 trees are felled and migrated to the station perimeter from the sub-tornado. Average tree diameter 18". Trunks of these trees are piled ready for removal.

• The hatchery also has a 14' high by 30' diameter pile of the limbs, broken debris, and small diameter trees ready for chipping, removal, or burning

C. NEW TREES

o The storm removal of trees have downgraded the keystone visitor and public recreational area for the fish hatchery. Replanting as many trees as possible will go a long way to recovery. Full size trees are not viable, but a reasonable compromise between, size/cost should get us to a better starting point than just seedlings.

o This project includes planting trees with a survival expectation, please include a 2 year survival rate with the anticipated planting measures.

o Please include a cost per tree planting so the station and contracting can determine a responsible use of funding to determine the number and species to be planted.

o Replace trees in marked areas with 10ft+ trees. Trees must be species that are native to Tennessee. Please provide a list of size/pricing for the following trees:

• Eastern Red Cedar

• Southern Magnolia

• Sycamore

• Blue Spruce

• American Holly

• Leyland Cypress

• Pecan Tree

• White Ash

• Bald Cypress

D. SECTION: EROSION MITIGATION

o The loss of trees and full root balls from storm damage is compromising the creek banks. While planting trees will help in the long-term, Some additional fill and compaction with soil/rocks will help prevent further damage while the new trees are growing.

• Fill marked tree root pits in storm damaged areas with compacted soil and topsoil

• Patch repair asphalt in storm damage path areas. Full repair is not required as part of this project, just the marked areas impacted by felled trees and cleanup heavy equipment.

• Replace/Add rocks as riprap in marked areas damaged directly or indirectly by storm damage and loss of forest integrity
