Caño Martín Peña – Comprehensive Infrastructure Master Plan

The one square mile District of Caño Martín Peña is located between Luis Muñoz Marín International Airport and the resorts of the Condado District and Downtown San Juan.  The district sits along the Martín Peña channel, a narrow body of water that connects the Bay of San Juan with the San José Lagoon.  This unique area is both the only protected tropical estuary in the United States and home to 12,000 residents in eight neighborhoods. These residents live with severe exposures to flood risk and a lack of sanitation infrastructure, safe housing, and roads. The comprehensive infrastructure master plan is a holistic approach to community health, economic well-being, and environmental restoration through infrastructure redevelopment, water quality improvements, new housing, and climate adaptation interventions. Over a two-year inclusive planning process, OLIN led a comprehensive planning and infrastructure effort with ECo Design Studio, Arcadis, and eDesign Dynamics among a larger consulting team of resilience planners, architects, engineers, and transportation planners.

ECo spearheaded the housing and green infrastructure initiatives, and the local community engagement.
