| | | | | | | | | TITLE: | DISCUSSION ON CITY OF MIAMI BEACH STORMWATER, SANITARY, SEWER AND WATER INFRASTRUCTURE BEST MANAGEMENT PRACTICES. |
| |
| | | | | | | | HISTORY:
| | The City of Miami Beach implements a proactive approach to managing its water, wastewater, and stormwater infrastructure. As part of this approach, there are various Best Management Practices (BMPs) that assist the City in optimizing its operations while achieving strategic goals, such as improving regional water quality and providing the highest level of service to the City’s stakeholders. |
|
| | | | | | | | ANALYSIS:
| Infrastructure Best Management Practices are an effective and practical means to improve resilience and efficiency, while providing environmental benefits. Many of these practices are shared across systems. For example, updating public works standards will benefit all City infrastructure, while a valve exercising program is integral to a well-maintained water and sewer system.
Beyond the systems they improve, BMPs can be broadly categorized within three separate groups: operational, planning & design, and stakeholder BMPs. The below table provides a summary of the most critical BMPs that are implemented to maintain our water, wastewater, and stormwater systems. The table also enumerates the main benefits derived from each BMP.

|
FISCAL IMPACT
There is no fiscal impact, beyond the existing capital and operating budgets, to keep the current level of service describe above. Any additional BMP’s would have to be evaluated on a case by case basis.
|
|
| | | | | | | | CONCLUSION:
| Improving communications, operations, planning, and engineering design by implementation of BMPs allows the water, wastewater, and stormwater systems to become increasingly resilient and efficient. Staff is always working towards improving their management of these systems and therefore, always working to implement the latest best management practices. Staff will continue to stay at the forefront of the industry and implement the best available technologies to manage our water, wastewater, and stormwater systems.
