The work performed under an agreement with the Camino Real Regional Mobility Authority (CRRMA) consisted in the addition of two lanes (one in each direction) to the existing Loop 375 (Americas Avenue) facility for an approximately 6.1-mile-long distance. VILLAVERDE INC. responsibility in this project was to perform a schematic drainage analysis to convey and handle the additional water generated by the improvements proposed. Reinforced concrete pipes, retention basins, and miscellaneous drainage structures such as flumes, inlets, manholes, and junction boxes were designed in the schematic drainage analysis.
