The Río de la Plata basin is located about 11 miles west of San Juan and drains approximately 240 square miles. Heavy rainfall combined with the steep headwater slopes causes frequent flooding in the towns of Dorado, Toa Baja, and Toa Alta. The recommended plan provides 100 year protection upstream of PR Highway 2 and SPF protection downstream. Project features consist of 7.0 miles of channel improvements, 7.6 miles of levees, the replacement of 3 bridges, recreation facilities, and mitigation for the loss of environmental habitats. The Water Resources Development Act of 1990 authorized this project.
