As specialized <br />consultants, we will incorporate the use of best practices and technology for civil, marine <br />structural and coastal engineering design. The project examples below incorporate <br />innovative design concepts which can be implemented in future projects issued under the <br />City’s contract. <br /> <br />Civil Engineering: <br /> <br />The Miracle Mile & Giralda Avenue Streetscape Improvements project’s drainage design <br />incorporated a stormwater management system that used a combination of exfiltration <br />trenches, with structural soil under the pavement to provide additional stormwater storage. <br />The system also included Storm Capture Modules (open bottom concrete structures) which <br />provide additional storage with the ability to discharge into the water table. The system <br />included several overflow connections that discharge to the City’s overall master stormwater <br />system. This effective drainage system, combined with pervious pavement and proper <br />conveyance of surface water discharge, allowed for Miracle Mile to be designed for the 100 <br />year – 1-day storm event without the use of expensive pump systems. The pervious paver <br />design took advantage of new South Florida Water Management (SFWMD) policies and <br />reduced site run-off. <br /> <br />Bayshore Park in Miami Beach sets precedent in the City by promoting sustainable <br />management practices. The purpose is to create a park of natural beauty for community <br />enjoyment and enrichment, reflecting the City’s culture and ecology while serving as a <br />model of sustainability, stewardship, and resilience. Coastal Systems is designing the <br />resiliency functionality and sustainable elements that can be incorporated into the <br />community park to treat stormwater runoff for the surrounding neighborhood watershed, <br />such as onsite water storage and pretreatment. The drainage system design incorporates <br />green infrastructure and a 3-acre lake for retention capacities that consider higher water <br />tables associated with sea level rise predictions. <br /> <br />In the Capri South Beach project, Coastal Systems provided streetscape design services to <br />improve the right-of-way for 16th Street and Lincoln Terrace street ends. Both street ends <br />were low in elevation, adjacent to the bay and presented challenges for the drainage design. <br />Several options were evaluated and an inverted-crown configuration for the street ends was <br />selected. The drainage improvements included a design combination of a gravity system, <br />stormwater pump stations and outfall structures. The improvements prevent bay water from <br />back flowing into the streets and protect the bay bottom from disturbance. Standards were <br />developed in the City Right-Of-Way for outfalls to the bay that include a structure to conceal <br />these large Tideflex valves. These check valves, along with the pumping system, were <br />designed to facilitate stormwater management for the City. The resulting design – outfall
