A Resilient Vision for low Elevation Streets in Miami Beach

CHALLENGES Miami Beach is a network of coastal berms and man-made barrier islands that abuts the ocean to the east and slopes downward toward Biscayne Bay. Miami Beach has 70 mi of shoreline and numerous canals and waterways. Many areas on the “bay side” are less than 1.5ft above sea level. As a consequence of this low elevation and the high conductivity of the oolite limestone subsurface, the bay side suffers from tide induced “sunny day” floods and is extremely underprepared for hurricane storm surges. The City of Miami Beach is currently pursuing gray solutions such as elevating streets and adding massive pumps. However, the current approach exacerbates runoff onto private properties and creates community harmonization challenges. DESIGN & CONCEPT We’ve designed a resilient vision for West Avenue, the lowest-lying major street, which aims to equitably and affordably safeguard the neighborhood for future generations. The design is centered in stormwater water management, and includes public rail transportation capable of withstanding Category 4 Hurricanes. Instead of investing over $658 million to raise roads and public seawalls , let’s embrace our future of living with water by giving it some Miami Beach flair.

This is a method of recycling the worn top coat in the new base, thus making it more resistant to flooding and reducing waste. Pervious Surfaces Following road recommendations specified by the Next Generation Council motion voted 7-0 in favor by the Commission Require that all new and repaired public and private driveways, sidewalks and surface parking areas be made with previous concrete or asphalt pavement.
