The Challenge

Miami-Dade County is vulnerable to rising sea levels, which has the potential to lead to more frequent and severe flooding. Flooding can result in short-term and long-term impacts to County residents and infrastructure—residential and commercial property damages; potentially affect property values; reduce water quality; and cause a temporary loss of parking spaces, green parks, and other public spaces. Rising sea levels and flooding may affect many residents, properties, and infrastructure assets across the county. One area that has experienced more flooding historically is the Arch Creek Basin.

Arch Creek Basin is a 2,838-acre drainage basin that is economically diverse, densely populated, and may be benefiting from a new commuter-rail station as part of the Coastal Link Tri-Rail expansion. The Arch Creek Basin area includes land in North Miami, North Miami Beach, Miami Shores, Biscayne Park and unincorporated Miami-Dade County. The stormwater basin is an area of relatively low-elevation, which creates challenges for the existing drainage systems. The Arch Creek Basin also has many sites with impervious surfaces. These sites contribute to localized flooding, which has on occasion become severe during storm events. The area is also vulnerable to flooding from tropical storm surge and high-tide events. Many streets are affected by temporary flooding due to their low-elevation, proximity to the groundwater table, and proximity to the bay during “king tides” (seasonal high tides). There is already a concerted effort—by policymakers, professionals, and citizen groups—to find innovative, scalable approaches to address the effects of climate change and protect residents in a way that is both environmentally and financially sustainable.

Miami-Dade County is calling for ideas to help minimize the risk of flooding from rain events in the Arch Creek Basin—reducing the risk of disaster and making communities more resilient to the impact of climate change.

What Miami-Dade County is Looking For

This RFI is a call for creative proposals of all types on how to reduce flood risks in the Arch Creek Basin without significantly increasing energy demand for water management. The County is looking for small-scale interventions that can be used in neighborhoods, which will complement countywide, large-scale infrastructure projects. Ideally, these solutions would be passively maintained and would require low or no continual energy inputs, and they should be cost-effective so that they can be scaled up across the County.

The County is looking for solutions beyond the typical “off the shelf” engineering solutions of pipes and pumps, as some of the traditional interventions can be expensive, may only provide limited additional protection in the case of severe storms, and may not build incremental protection to sea level rise. Responders can propose tested solutions as well as novel ideas.

The County is strongly interested in innovative, cost-effective solutions that require minimal energy inputs and accommodate the daily needs of residents such as space for recreation.

The County is also highly interested in Low Impact Development practices and solutions that are sustainable and improve water quality as well as data management solutions and monitoring systems in the field of water management. All proposals that involve the collection of rain water must demonstrate due consideration of the need for mosquito control measures.

The Opportunity

An RFI is an alternative to a county procurement, in which the Miami-Dade County first seeks information about available solutions to a problem. The County will invite at least two responders to meet with a variety of County stakeholders to discuss their proposed solutions in greater detail as well as potential implementation options. After meeting with the responders, the County may decide to procure and implement one or both solutions submitted to this RFI.
