If you see this message when pressing Continue:

“The total area of intended habitat parcels (newly created area) should be equal to the total area lost of existing habitat parcels on your site…”

And you’re unable to move forward, please email info@joesblooms.com to get support.

Here’s what’s happening and what to do.

🔎 What This Error Means

The system is currently checking that:

Total area of habitats being created = Total area of habitats being lost

Step 1️⃣ – Check the Baseline Covers 100% of the Red Line

Step 2️⃣ – Redraw Post-Development Parcels One by One

  1. Delete one post-development parcel.

  2. Redraw it cleanly.

  3. Press save.

  4. Check if the totals move closer together.

If not:

  • Delete the next one.

  • Redraw.

  • Repeat.
