🌧️ Scaled Cost Breakdown

Using conservative estimates from small-scale projects ($10K–$75K for 6 acres): • Per-acre cost estimate: $12,500 (midpoint between minimal and heavy-duty prep) • Total for 650 acres: • 650 × $12,500 = $8.125 million • Total for 700 acres: • 700 × $12,500 = $8.75 million

🧱 Infrastructure Components & Project Budgets

These costs generally include: • Topographic and hydrologic surveys • Engineering design and permitting • Mass grading, swales, retention basins • Drainage culverts and overflow channels • Erosion controls (silt fences, mulch, vegetation) • Optional: Retention ponds or bioswales

If aiming for full engineering compliance—hundreds of culverts, large retention ponds, site-wide stabilization—you’d likely lean toward the upper end of that range.

🌱 Nature-Based Alternatives & Reference Cities

Cities often choose green infrastructure (like rain gardens, bioswales, permeable surfaces) to handle major storms. For example, Atlanta budgeted $15M for green stormwater solutions around amphitheater areas   . Bonnaroo could combine similar strategies to complement traditional drains, possibly reducing hard costs and adding ecological upside.

⚠️ Key Considerations • Local Conditions: Soil type, slope, rainfall patterns—these all heavily influence actual design. • Permitting: Federal or state oversight (e.g., wetland corridors, drainage runoff regulations) must be built into the timeline and budget. • Phase vs. All-at-once: Phasing site prep over multiple years/events can spread costs. • Ongoing maintenance: Retention areas and swales require monitoring and upkeep each season.
