lip A Architectural, Landscape Architectural, Engineering and Land Surveying Firms Only (CCNA) Government Cut Force Main Phase 1, Miami -Dade Water and Sewer Department, Miami, FL This project consisted of a route study and evaluation for a force main to convey wastewater from the City of Miami Beach (an island) to the Virginia Key WWTP (on an island). This required an underwater route. Kimley -Horn developed a list of 12 alternative routes, and narrowed the list down to 3 viable alternatives. One route required use of the Port of Miami as a landing point, another route required using Fischer Island as a landing point, and the last route was a completely underwater route. Each route presented challenges, including disruption of Port activities, disruption of extremely wealthy neighborhoods and the acquisition of necessary easements, and the use of numerous caissons in the Biscayne Bay. A matrix of alternatives was developed using 18 weighted factors under consideration. Ultimately, a route was selected which required approximately 2 miles of 32 -inch diameter directionally - drilled force main. Geotechnical considerations were extremely important, and extensive soil borings 200 -feet deep were required.

This force main will serve as redundant line to the existing 30 -inch and 20 -inch force mains running along West Dixie Highway. Kimley- Horn's design provides for a redundant connection between Pump Station 423 (Discharge Point) continuing south to a point of connection with an existing 72 -inch PCCP force main (located approximately at the intersection between NE 19th Place and NE 159thStreet). We are also designing a subaqueous canal crossing across Snake Creek Canal as part of this project. The line work under Snake Creek Canal will consist of a horizontal directional drill under the canal to avoid impacts to Waters of the State. Since this proposed approach will result in no impacts to wetland resources or Waters of the State, no mitigation will be required for project approval and implementation. Collins Avenue Water and Sanitary Sewer Improvements, Miami Beach, FL The City of Miami Beach selected our firm to provide fast -track design, permitting, and construction administration for water main and sanitary sewer improvements associated with new high -rise developments along Collins Avenue. We met a tight project schedule and coordinated closely with a hotel developer to ensure that utility service connections to the Lowe's Convention Center Hotel were placed in time for the hotel opening. We also worked with Florida Power and Light (FP &L) throughout the project to resolve the conflict of proposed water lines with existing FP &L duct banks. Our coordination with area stakeholders minimized impacts to the public. In fact, most of the construction along Collins Avenue occurred at night to avoid closing the road during the day. Before we completed the project, we provided additional restoration to sidewalks and curb and gutters adjacent to the project site. This additional restoration assured the City of a consistent appearance along Collins Avenue. 48 -inch Force Main along Sunny Isles Boulevard. Miami -Dade Water and Sewer Department, Miami, FL Kimley -Horn is responsible for the design of a 48 -inch Force Main along Sunny Isles Boulevard. The project consists of installing approximately 7,700 linear feet of a 48 -inch D.I. (I.D.) and 5,200 linear feet of twin 48 -inch H.D.P.E. (O.D.) force mains. The new force main will connect to an existing 48 -inch force main just west of the Intracostal Waterway, and convey raw sewage from Pump Stations 301 and 426 west along Sunny Isles Blvd (SR 826) to approximately 1,000 linear feet west of the Oleta River. At that point, it will manifold with an existing 48 -inch force main and continue south approximately 3,000 linear feet across the Oleta River State Recreation Area to the MDWASD North District Wastewater Treatment Plant, where it will connect to the chloride side of the plant. The project will require an aerial crossing of the Oleta River, and coordination with FDEP for proposed impacts to State Wetlands. a O14o7o oYF., !14 -0 S =.Y 1s 6eac, Ca4n PNessional seMms.iro] Kimley)>>Horn
