The proposal is also characterized by a sustainability criteria in building design and urban design strategies with bioclimatic design criteria, efficient management of energy and water, the use of low environmental impact construction materials, sustainable management of urban space : biodiversity conservation, thermal habitability, sustainable drainage systems, improving soil permeability and recycling.

All over town there are no rivers due to high soil permeability, thi is a characteristic of the Yucatan area, water seeps into the ground where it forms underground rivers that form cenotes, which are outcrops to the surface of these subterranean river, in Telchac Pueblo there are 11 cenotes, 10 of which are open and a 1 semi-open.

The heavy duty disc with large diameter disc blades of 26 ", 28 ", 30 ", 32 ", 36 ", and 40 ", and with increased disc spacings of 10 ", 14 ", and 18 " are the primary tillage tools that are used to break virgin ground, to incorporate residue into the soil in preparation for a ripper / subsoiler, and to break up a compacted soil in order to increase soil aeration and to promote soil permeability in lower levels of the soil profile.

Formed initially as a company-size element from the Observer Group, under the command of Major Underwater Demolition Teams [ i . e ., the Navy SEALs ] ) to embark from submarines; most of their missions complemented those of the NCDU and the UDT . The'amphibious reconnaissance'doctrine clearly outlined that the recon Marines'duties consisted of scouting the littoral areas, or beachhead, and inland; to test the soil permeability for a possible beach landing; to clear any obstacles that may hinder an amphibious assault; and to observe any sign of enemy activity.
