Quebrada Margarita

Design & Construction Contract No. 1

98%
Summer 2026
Fall 2031

Located in the Matadero industrial area of Guaynabo, the work completed during this phase will connect the upper Quebrada Margarita to the completed portion of the project immediately downstream of the de Diego Expressway. Currently, the channel is too shallow and clogged with debris. This means that rainstorms quickly fill the channel and floods into nearby parking lots and buildings.

Project Information

After construction, the channel will be deepened and widened to improve channel capacity and efficiently convey water downstream.
Quebrada Margarita is a very narrow channel between the Matadero industrial area and the de Diego Expressway.
As part of the construction sequencing, electrical transmission and distribution lines will be relocated and updated per the latest engineering standards.

Upper Margarita Channel

Design & Construction Contract No. 1

Construction will deepen and widen the channel. New reinforced concrete walls and channel bottom will be built. The channel bottom will be constructed with smooth concrete to allow for rainwater and stormwater to efficiently pass through the area and out into the Margarita Channel, Río Puerto Nuevo, and San Juan Bay.

Additionally, above ground utilities will be buried underground and LUMA’s large, 115kv transmission lines will be relocated from the south to the north side of the channel. Relocating the utilities will enhance resiliency to floods and wind, and promote continuity of vital services such as water, wastewater, and electricity during flood events.

Construction Information

Construction information will be released after the project is awarded to a contractor in Summer 2026.
