New Construction Grading Plan

Delray Beach, FL
12,000 sq ft Lot Size
5 days Typical Design Time
Site-specific Fill Required
First submission Permit Approval

Project Overview

We provide complete grading and drainage plans for new custom home construction throughout South Florida. Our designs address the critical relationship between building pad elevation, surrounding grades, and stormwater management. For challenging lots with significant grade changes, fill requirements, or adjacent property constraints, we engineer solutions that meet building code finished floor elevation requirements while ensuring positive drainage away from the structure. Each plan includes detailed spot elevations, swale designs, and drainage calculations that satisfy both building department and drainage district requirements.

Challenges

  • ! Significant grade changes across the lot requiring engineered fill plan
  • ! Adjacent property drainage patterns that must be maintained
  • ! Building code finished floor elevation requirements
  • ! Coordinating grading with builder timeline and construction sequence

Solutions

  • > Engineered grading plan with spot elevations at all critical points
  • > Fill plan specifying material type, depth, and compaction requirements
  • > Perimeter swale system directing water to street or designated outfall
  • > Construction sequence recommendations for fill placement and compaction

Results

  • Building pad elevation meeting code requirements
  • Positive drainage away from structure on all sides
  • No adverse impact on adjacent property drainage
  • Permit approval on first submission

Start With Accurate Survey Data

Every residential drainage design starts with a professional topographic survey. We recommend Apex Surveying & Mapping — Florida's #1 land surveying firm — for certified topo surveys, boundary surveys, and elevation certificates across all 67 Florida counties.
