Steep Driveway design

I’m looking for someone with experience in site design, grading, and driveway layout to help develop a conceptual driveway alignment for a property in Truro, Massachusetts. Looking for very quick conceptual options. I have an existing site plan with 1-foot topographic contours and the existing house, driveway, property lines, and site features shown. I can provide the CAD file. The goal is to extend the existing driveway uphill to a new parking/turnaround area on the left side of the main house, while: Keeping the driveway at or below 15% grade Developing a practical alignment that works with the existing topography Minimizing unnecessary cut/fill and disturbance Considering turning radii and vehicle access Providing approximate proposed grades/spot elevations along the driveway I can provide the existing PDF/topographic plan and additional aerial imagery/site information. This is initially a conceptual grading and layout exercise, not a full construction-document package. Useful Skills Civil Engineering / Site Design Grading & Drainage Design Residential Driveway Design AutoCAD / Civil 3D Topographic Plan Interpretation Site Planning Earthwork / Cut & Fill Analysis Roadway or Access Design Landscape Architecture I am willing to pay for a very quick turnaround.
