What's included

Your payment includes:

Compliance Validation
Your design is validated against the MWELO requirements, hydrozone by hydrozone, so you know it is ready before it reaches plan check.
Built-in WUCOLS Plant Selector, including Fuel Modification Check (when applicable)
3,500+ species, with only the plants rated for your region on offer and the correct water-use category and plant factor applied automatically — so a plant choice is never in doubt. If your project is subject to fuel modification, the same search also flags plants on the standard fire-agency undesirable list.
Address-Specific ETo Data
Evapotranspiration figures pulled for your exact city — not regional averages.
Unlimited Revisions
Edit and re-validate as many times as needed, until your design is validated for MWELO compliance for your project address, at no extra charge. Only the project location — address and city — stays locked.
Compliance Documents
Open, print or download the Water Efficient Landscape Worksheet, Hydrozones Information Table, Plant Material Table, and a Certificate of Completion PDF pre-filled with your project address — ready to include with your permit application. Documents unlock once your design is validated.
Your project includes four documents:
01Water Efficient Landscape Worksheet
02Hydrozones Information Table
03Plant Material Table (by hydrozone)
04Certificate of Completion (PDF, pre-filled with your address)
