In 2002, spurred on by quarrying activities in El Chorro and Acono, Maracas Valley residents came together to address these and other concerns which were negatively affecting life in the Valley including:
- water pollution due to ineffective water treatment facilities.
- increasing demand on an already beleaguered infrastructure due to a rapidly increasing population.
-deforestation (and accompanying issues of soil erosion and flooding).
Sub-Committees were set up to address various concerns in the Valley following the first meeting of Concerned Residents ( held on June 23rd 2002) . Thomas Gudat was the driving force behind this effort and eventually became the first President/Chairman of what was then called the "Interim Committee of the Maracas Valley Action Committee". He served until 2004 and was instrumental in the drive to register MVAC as a non-profit group.
MVAC was formally incorporated as a Not for Profit Company under the Companies Act, 1995 of Trinidad and Tobago on 17th November 2004 . A revised constitution was formally accepted at the general meeting held on July 3rd 2005 and took effect from July 14th 2005.
