RFQ # 26-07-01 | CITY OF SUNNY ISLES BEACH 51 CES CONSULTANTS, INC. The purpose of the project was to provide drainage and traffic improvements through roadway widening, median installations, redesign of intersections, and improvements to drainage, parking, lighting, signalization and landscaping in the Coconut Grove neighborhood of the City of Miami. The land use is a combination of residential and commercial. Since the roadway is part of an older, well established neighborhood, many different utilities are installed within the right of way. The project corridor includes a 30-inch water main, smaller water mains, gas, multiple fiber-optic cable duct banks, sanitary sewers and force mains, requiring extensive utility and interagency coordination. Other complicating factors in the design were the elevations, which included low grades and a high groundwater table at the southern end of the project directly adjacent to Biscayne Bay, higher elevations in the mid-section, and “normal” elevations around the northern end. The final cross-section of the roadway included additional vehicular travel lanes, sidewalk, curbing, drainage, on-street parking, a bicycle lane, and a traffic calming circle. The design required a clean transition through planned driveway and property harmonization between the new roadway and the existing private property ingress and egress to match the new roadway elevation, width and contours. Additionally, the project required intensive utility coordination to execute the necessary utility relocations, including coordinating with FPL to remove the existing power poles and install all their assets below ground. The stormwater drainage design was developed in accordance with the guidelines set forth by the County and the Florida Department of Transportation. The design consists of approximately 70 drainage structures to capture and convey all the stormwater, 3,000 LF of piping and 2,000 LF of French drains divided into eight (8) independent, closed systems. By creating independent systems, CES was able to develop a design that satisfied the project requirements while achieving significant cost savings to the client compared to their customary approach of creating interdependent systems.
