OPA-LOCKA MITIGATION STRATEGY PROJECT

Project Description

The City received Flood Mitigation Assistance Grants from the Federal Emergency Management Agency, (FEMA) and also from the Florida Department of Environmental Protection (FDEP) for restoration and rehabilitation of flood-damaged drainage systems within the city. The City of Opa-Locka suffered severe flooding during Hurricane Irene in 1999 and again during the “No Name Storm” of 2000. The City contracted Post, Buckley, Schuh & Jernigan (PBS&J) to provide, professional services needed to fulfill the project requirements.
EBS Engineering, Inc., as subconsultant to PBS&J was responsible of providing the following services:

Stormwater System Inventory:
EBS provided the field project teams that collected data on the existing condition of the canals and conducted an inventory of all the stormwater structures, canals, channels, culverts, catch basins, street inlets, pipes and retention areas in the city. The field data and conditions of the stormwater structures were analyzed and input into a GIS database using an aerial map of the city for planning and future construction work.
The aerial map also contains clean-up and/or repairs recommendations for the dysfunctional stormwater structures. The structures were prioritized based on the existing conditions, location and size for ranking as to which structures would be cleaned or repaired first.

Design Services:
EBS also assisted PBS&J with the dredging design of the canal restoration, designing for the banks stabilization, dredging quantities and other improvement structures including selection of rip-rap materials, geoweb, etc., and assisting in the preparation of detailed construction plans, and supplemental CADD services for all other construction documents.

Construction Phase Services:
EBS provided experienced construction inspectors for the duration of the project to periodically observe construction progress including photo documentation and daily reports to the PBS&J’s construction manager. Construction inspections were conducted concurrently on several canal segments and other ongoing activities.
