Acreage pricing

Base pricing covers sites up to 10 acres. Monthly adjustments for larger sites:

Site size	Monthly adjustment
Up to 10 acres	Included in base price
10-25 acres	+$430/month
25-50 acres	+$1,080/month
50-100 acres	+$2,165/month
100+ acres	Custom proposal

A 40-acre site on the Professional plan would start at $2,595 + $1,080 = $3,675/month.

Compliance+ weather monitoring add-on

$299 per month per site. Automatic rain event tracking and inspection scheduling for sites where the 24-hour trigger is the primary compliance risk.

Automatic weather monitoring tied to permit rainfall threshold (0.5 inches)
Inspection scheduled automatically after a qualifying rainfall event
Email and text notification when a rain event inspection is triggered
Rainfall history log
Compliance calendar showing inspection dates and rain events
Discounted rain event inspections: $225 per event (vs. $325 standard)

For sites with active grading where rain event violations are the most likely compliance issue, Compliance+ converts the 24-hour inspection requirement into an automated workflow rather than a manual response.

Rain event inspections

Available on-demand for any active NPDES-permitted site, regardless of plan.

Standard (no active plan): starting at $325 per event
Compliance+ customers: starting at $225 per event

Rain event inspections are available same-day for sites in Greenville, Spartanburg, Anderson, Pickens, and Oconee counties. Deliverables within 24 hours of the flight.

Additional inspection triggers

BMP inspections outside the weekly schedule are available at the per-event rate for:

Qualifying rainfall events (0.5 inches or greater in 24 hours)
Before a scheduled SCDHEC inspection
After BMP repair or reinstallation
Major construction phase changes (clearing complete, grading complete, building start)
Complaint investigation or sediment release documentation
Project closeout and final stabilization documentation

Pricing notes

All pricing is per site and billed monthly. Final pricing may be adjusted for travel distance beyond standard service area, restricted airspace requiring additional coordination, or site complexity. Sites over 100 acres or with unusual access requirements are quoted individually.

For SWPPP consultants managing multiple active sites, the Managed Compliance plan includes a dedicated account manager, multi-site dashboard, and custom reporting. For consultant-specific pricing and program structure, see drone inspection support for SWPPP consultants.
