Is the plan you were given complete?
A federal-zone delimitation plan must carry fourteen things, and the list is published in Mexico’s official gazette. Tick off what yours has and we tell you what is missing and what it means. We ask for nothing and you upload nothing.
What actually helps
Upload your plan and we will review it
C.P. Israel Bross reads it and gets back to you. If it is a PDF with a text layer, you also get a preliminary reading right away.
We have your plan.
The accountant will review it and reply to the number you gave us.
Or check it yourself
If you would rather not upload anything, tick what your plan has and we give you the same list.
Have the plan in front of you and tick what you find.
Report
This is a review of the document against the gazette’s list, not of the measurement. If you want to know what it means in your case — and whether a formal survey is worth requesting — write to us and we will go through it with you.
Ask about my caseWhy the date on the plan matters
The standard in force, NOM-146-SEMARNAT-2017, took effect on 12 February 2018 and requires horizontal accuracy better than 50 centimetres. Everything surveyed before that was done under the 2005 methodology.
In Baja California Sur that covers the vast majority of published plans. It does not make them invalid — they remain the official delimitation — but it explains why a formal survey can change the answer.
There is a second, less known reason: the standard defines mean high tide as the highest level recorded over thirty consecutive days, drawn from up to nineteen years of records. The line is measured to the centimetre against a reference that moves over time.
This tool checks your plan against the list of elements in Appendix A of NOM-146-SEMARNAT-2017. It does not review the measurement — that requires field work — and does not replace a formal survey before the Dirección General de Zona Federal Marítimo Terrestre y Ambientes Costeros. A formally complete plan is not necessarily a correct delimitation, nor the other way round.
