Before Z After

Will they actually start this project before fixing the sewer plant that drains into the lagoon?

Yes, the dredging begins in a couple of weeks and is scheduled to last 6 months. The treatment plant isn't scheduled to be finished and fully operational until March 2015.

They are NOT going to block the water in lagoon from escaping into the bay during the dredging, so I'm fully expecting not only our summer tourist vacation season to be ruined but also next winter's. I do NOT have confidence in the government making sure to plan carefully. All the local bigwigs are too busy building their new homes (as well as for their family members) and stuffing their pockets and getting ready for the next elections. They just don't seem to care enough to take the time to plan carefully, and much less to listen to the public or seek expert opinions. Remember, they have had their priorities in the wrong order since entering office, and that speaks volumes.

This is going to get real interesting as more locals catch on to what's going on and start asking questions. How long will it be until they demand answers?

Lots of folks, including us, will be closely monitoring the Message Board over the next 6 months for information far more critical to our vacation plans than the latest Zihua restaurant openings/closings.
When I first read of the proposed dredging of Las Salinas, I naively assumed it had something to do with an attempt to control or eliminate the stench that increasingly fouls the air in and around Centro.
Instead, not only does it sound like the odour problems could be magnified exponentially - possibly for many months - but the beaches, already only borderline-safe for swimming, may also be adversely-affected.... for months.
Our last digs in Centro gave us a direct line of sight (and smell) to Las Salinas. From what I've read here, that location might not be where one would want to spend next tourist season.
I think I'll postpone any thoughts of advance booking until the water seems less murky, so to speak.
