Marinas or Mangroves?

Ambitious marina plan scaled back, and to those with environmental conserns, that's a good thing

My colleague, Jimm Budd, a Mexico City-based travel journalist who sends out daily reports about Mexican tourism, today reported that "Escalera Nautica today has 8 marinas open with seven more in planning stage according to Raul Lopez, manager at San Blas. Not exactly what had been dreamed of a decade ago, but still something. A decade ago, when the project was announced, goal was to open more than 30 marinas along both coasts of the Baja California peninsula as well as along the west coast of the mainland. The government would provide the basic infrastructure, and it was hoped that private investors would come in with the amenities. Lack of enthusiasm on the part of private investors had apparently almost killed the scheme, although Lopez said laws protecting mangroves on the coast were more to blame. Eventual idea is to attract boaters starved for marinas in their home states to come to Mexico."

A website called BajaQuest had other numbers but quoted an earlier report on the same concept:
"The plan calls for 22 full-service marinas, 10 of them new. Of the 12
existing, seven will be improved and five are judged as already adequate. The 10
new marinas will be located on sites with natural shelter, or bays, a feature
the peninsula has in abundance. Five of these are to be in Baja California,
three in Baja California Sur, and one each in Sonora and Sinaloa."

"Additionally, the plan calls for an 84-mile highway route for towing boats
from one side of the peninsula to the other. This feature will allow boat
travelers quick access to either body of water for those without time or
interest in sailing around the southernmost tip of Baja California Sur. Further,
the plan calls for improving the road between Mexicali and San Felipe to allow
bigger-boat towing rigs crossborder access to the Sea of Cortes."

The map (above right) was released in 2001, showing the ambitious scale of the project then. Some people probably still support it. Along the Sea of Cortes, tourism officials have been calling it "the mega-tourism project of the XXI century." That in itself is scary -- especially if you're a mangrove tree or a critter that lives in the mangroves. Environmental authorities call mangroves "the nursery of the seas." These miraculous trees survive and thrive in brackish coastal waters. Their complex root systems provide safe havens for hatchlings of all sorts, and birds nest in the dense foliage. Insects and everything above them in the food chain thrive in mangroves.

Miraculous Mangroves

Researchers Speak

The early stages of the Escalara Nautica were not encouraging vis-a-vis environmental stewardship. Back in April 2003 (more than six years ago), the California-based Algalita Marine Research Foundation published its "Preliminary Coastal Analysis of Escalera Nautica at Bahia Santa Rosaliita." This first marina did not involve mangroves, but if the Mexican government and/or developers didn't begin pay more attention to what it was doing, it must be bad news for mangroves and everything else along the Escalera Nautica. According to the report,

"The new marina is located in the northwest somewhat sheltered corner of
Bahia Santa Rosaliita (also spelled Rosalillita, Rosalilita, Rosalia)....The new
marina is located in the northwest somewhat sheltered corner of Bahia Santa
Rosaliita (also spelled Rosalillita, Rosalilita, Rosalia)....

"A new concrete wall (less than one year old) was observed to be heavily
damaged, with extensive cracking, spalling, and exposed rebar. Likely reasons
for this rapid deterioration are poor materials and construction
methods.

"Due to the short jetty length and ample availability of sediment in the
area, it is expected to be difficult to maintain the entrance depth required for
a navigable entrance.... aves will likely break across the marina entrance
during high wave events. Continuous dredging will be required to maintain the
requisite entrance depth and sufficient basin depth.

"Currently, the east jetty extends landward to approximately 10 meters
landward of the vegetation line. It is reasonable to expect the beach east of
the marina to continue to recede landward, likely resulting in erosion behind
the landward end of the east jetty.

"Extensive downcoast erosion has been measured during the first year after
jetty construction. It is expected that some structures will be lost to the sea
within another year. The historic sandy beach that did exist on the east of the
marina has been replaced by a steep cobble and stone berm with some exposed
bedrock and vertical sandstone beach scarping. The downcoast erosion will likely
reach a dynamic equilibrium within a few years."

"The first marina of the Escalera Nautica system is deeply troubled.
The lack of planning and poor selection of location has resulted in a marina
that will be very expensive to maintain. If it is determined that the marina is
essential, we recommend some improvements that will make the marina useful some of the time....

Future Escalera Nautica projects should consult qualified consultants and
perform adequate studies prior to construction."

I sure hope the government and developers have been doing precisely that, but I'm not taking bets.
