Wetlands Mitigation

Avoid, minimize, and—when required—mitigate. We construct wetland restoration and enhancement that meets Section 404/401 and TDEC ARAP requirements.

Practical compliance, built for our terrain.
Davis & Sons partners with your engineer and biologists to deliver permit-ready plans and construct mitigation that meets federal Section 404/401 requirements and Tennessee’s ARAP program—so you can keep your project moving and satisfy compensatory mitigation obligations.

What we do

  • Field + pre-con: support wetland delineations (1987 Corps Manual + Eastern Mountains & Piedmont regional supplement), survey control, access planning, and constructability. Sacramento Districtnap.usace.army.mil
  • Permit strategy support: coordinate with your consultants on avoid/minimize alternatives and, if needed, compensatory mitigation via permittee-responsible work, mitigation banks, or in-lieu fee options per the federal Mitigation Rule (33 CFR Part 332). eCFR
  • Build the mitigation: grading and micro-topography, hydrologic connections, culvert/weir details, soil amendments, invasive removal, native plantings, temporary/permanent stabilization, and access restoration—constructed to plan and spec.
  • Documentation: photo logs, quantities, and as-built survey packages aligned with the Mitigation Rule’s plan/monitoring expectations. eCFRSacramento District

How the approvals typically work (summary)

  1. Delineation & JD – wetlands delineated using the 1987 Manual with the Eastern Mountains & Piedmont supplement for our region. Sacramento Districtnap.usace.army.mil
  2. Federal & state permits – USACE Section 404 authorization (often a Nationwide Permit for minimal effects) + state Section 401 certification/ARAP from TDEC for work in “waters of the state,” including wetlands. Missouri Valley NavigationNWD U.S. Army Corps of EngineersTennessee State Government
  3. Compensatory mitigation – if unavoidable impacts remain, mitigation follows 33 CFR Part 332 (bank, ILF, or permittee-responsible). Tennessee also publishes compensatory mitigation guidance/tools used by applicants. eCFRTennessee State Government

Note: Nationwide Permits run on set cycles (e.g., 2021 NWPs effective through March 2026) and are periodically reissued/updated; stay current as you plan. NWD U.S. Army Corps of EngineersFederal Register

Why Davis & Sons

  • Mountain-tested execution – tight access, steep grades, and variable soils handled safely and efficiently.
  • One team from dirt to delivery – earthwork, drainage details, and planting logistics under a single schedule.
  • Compliance-first mindset – we build to the engineer’s design and provide clean records for agency acceptance under Section 404/401 and ARAP. US EPATennessee State Government

Typical project types

  • Permittee-responsible wetland restoration, creation, enhancement
  • Roadway and site expansions with unavoidable wetland impacts
  • Utility corridors and plant sites requiring crossings or fills
  • Tie-ins to stream restoration when wetlands and buffers are linked

Deliverables

  • As-built survey + quantities keyed to plan sheets
  • Photo documentation and installation logs
  • Stabilization records and seed mixes used
  • Mitigation plan inputs (as needed) consistent with 33 CFR Part 332 expectations for performance, protection, and monitoring.

Tennessee considerations (at a glance)

  • TDEC requires ARAP/401 for alterations to streams, rivers, lakes, and wetlands; applicants use state mitigation guidance/tools where compensation is required.
  • Compensatory mitigation options include banks, in-lieu fee programs (where available), and permittee-responsible projects under the federal Mitigation Rule. Recent changes include a Stream Mitigation Fund for Tennessee established by NFWF, using funds from the former TSMP. (Wetland mitigation availability may differ; coordinate early.)

FAQs

What guidance governs wetland delineation here?

USACE’s 1987 Manual with the Eastern Mountains & Piedmont regional supplement.

When is compensatory mitigation required?

If, after avoidance/minimization, permitted impacts remain, compensatory mitigation may be required to comply with Section 404(b)(1) and 33 CFR Part 332. eCFR

Can smaller impacts use general permits?

Yes—many minimal-impact projects qualify for Nationwide Permits; terms/conditions and cycles apply. Your consultant coordinates with USACE/TDEC. Missouri Valley Navigation

Planning a project with potential wetland impacts?

  • Request a pre-design review (delineation status, permitting path, mitigation options).
  • Schedule a site walk to discuss access, phasing, and stabilization.
  • Ask dispatch about pairing trucking and erosion control to keep your window tight.
