Improvements included accesses to businesses and <br />parking lots, grading of the street to provide proper drainage and <br />new striping and signage for the design. The improvements were <br />from N.E. 2nd Avenue to 115 feet beyond N.E. 3rd Avenue <br />(approximately 800 It). The design of N.E. 59th Terrace is part of <br />the Little Haiti Cultural Center project funded by the City of <br />Miami and designed by Zyscovich. Coastal Systems provided <br />water and sewer design for the Little Haiti Cultural Club, Theatre <br />and Parking Lots. The design consist of SOO If of 12" D.I.P. water <br />mains which includes, two fire line services, two domestic water <br />service connections, and three irrigation water services for the <br />parking lots. All services were designed with backflow preventers. <br />Additionally, new sanitary sewer connections were designed to <br />replace older lines. Coastal Systems designed drainage systems to <br />manage on-site stormwater runoff. The site drainage design <br />consists of over 700 If which includes an exfiltration trench system <br />connected by 27 drainage structures. The street drainage design <br />consists of 525 If of exfiltration trench connecting 10 drainage <br />structures. Additionally, the stormwater runoff was managed by <br />the design of a complex RetentionlDetention System using (6) 4S" <br />diameter HDPE (High Density Polyethylene) pipes, 70 feet in <br />length each discharging into the ground. This drain field is being <br />used as an individual component to drain the site/roof area of over <br />1 acre, on land with poor soil percolation. Coastal Systems <br />processed the water/sewer system permits through Miami-Dade <br />W ASD, and the stormwater plans through Miami-Dade DERM. <br /> <br />Corporate Office: 464 South Dixie Highway.
