Chen and Associates is the prime consultant and is responsible for providing surveying, planning, geotechnical investigation, design, permitting, preparation of construction documents, bid and award and construction engineering and inspection services for infrastructure improvements within the public right of way areas of the City Center neighborhood of Miami Beach. The project encompasses approximately 24,000 LF of ROW infrastructure improvements including water main replacements, sanitary sewer upgrades, stormwater drainage improvements, paving & grading, streetscaping enhancements, landscaping improvements, lighting improvements, and roadway reconstruction. Due to the existing mixed residential and commercial environment of this neighborhood, special design efforts were made to incorporate walkable community elements including meeting all ADA requirements, providing street furniture, providing bicycle paths, upgrading sidewalks, incorporating specialty treatments at crosswalks, landscaping improvements with specialized tree wells to provide a walkable surface and bulb outs to increase pedestrian friendliness and safety. This project also required extensive coordination with the Public, adjacent CRAs, historic districts and various regulatory agencies.
As part of the proposed stormwater and drainage services, extensive analysis was conducted utilizing ICPR Modeling and GIS to meet and/or exceed required stormwater Level of Services standards. The proposed stormwater design included the introduction of catch basins and stormwater piping to effectively collect and route the stormwater to sixteen (16) drainage gravity wells with overflow outfall to Dade Canal. Water quality treatment was an important consideration and design factor of the system to ensure that appropriate treatment was provided prior to discharge to the gravity wells and outfalls.
