Land Development Consulting

At Dune Engineering, we see early project due diligence as one of the most valuable steps in the development process. It clarifies what's possible and lays out a clear path from concept to reality.

Feasibility starts with the fundamentals: identifying variances and permitting requirements early, and understanding constructability, local planning, zoning, and environmental regulations. Get these right upfront, and the rest of the project moves faster.

Here are some key due diligence considerations a successful developer needs to identify early:

  • Zoning Regulations

  • Availability of Utilities

  • Flood Hazard Area / Streams & Riparian Zones

  • Regulated Wetlands Areas & State Open Waters

  • Contaminated Soil or Groundwater

  • State Planning Areas

  • Easements / Deed Restrictions

  • and more…

Site / Civil Design

Our work sits at the intersection of developer vision, economic viability, local compliance, constructability, and environmental responsibility. Dune integrates these factors seamlessly to design site plan sets that not only get approved, but also respect the environment they'll sit in once built.

Dune provides site and civil engineering design services to bridge the gap from concept to completion. Our experienced civil engineers ensure your project is ready for construction.

Preparation of a full or partial set of site civil engineering plans could include:

  • Demolition Plans

  • Site Layout Plans

  • Grading, Drainage & Utility Site Plans

  • Soil Erosion & Sediment Control Site Plans

  • Landscaping & Lighting Site Plans

  • Traffic Control Plans

Other Civil Design services include:

  • Retaining Wall Design

  • Culvert Design

  • Transportation Engineering & Design

Planning & Approvals

Securing approvals from local, county, and state agencies takes careful planning and precise design — there's little room for guesswork. Dune prepares complete application submissions and provides expert engineering testimony at public hearings on your behalf.

Our attention to detail shows: plans that clearly demonstrate regulatory compliance, and give contractors the precise information they need to estimate costs accurately and build efficiently — with minimal change orders or RFIs.

Environmental Permitting

Environmental permitting is often the most complex and time-sensitive piece of the approval process — miss a requirement here, and the rest of the project stalls behind it. Dune navigates these regulations early, identifying environmentally sensitive areas and applicable permits before they become roadblocks to design or construction.

Our team prepares and manages permit applications across local, state, and federal environmental programs, keeping your project moving on a realistic timeline.

Environmental permitting services could include:

  • Wetlands Delineation, LOI & Permits

  • Flood Hazard Area Verification and Permits

  • Treatment Works Approval (TWA) Permits

  • Streams / Riparian Zone Permits

  • Highlands / Pinelands / CAFRA Permitting

Construction Phase Services

Plan approval isn't the finish line — it's the starting point for construction. Dune stays engaged through the build, making sure what gets constructed matches what was designed and approved.

Our team provides construction administration and observation, keeps cost estimates accurate as the project evolves, and responds quickly to RFIs to keep crews moving. We also handle stormwater inspections to keep the project compliant from groundbreaking to completion.
