Tetra Tech, Inc

Stormwater Master Plan Update
Key Biscayne, Florida
Project Highlights:
• The first task consisted
of inventorying and
mapping stormwater
infrastructure in the City
• The analysis consisted
of hydrologic and
hydraulic modeling
using XP SWMM
• Tetra Tech
concentrated on
repetitive loss
properties
Project Value:
Tetra Tech is currently contracted to provide professional engineering services for the
Village of Key Biscayne Stormwater Master Plan Update. This project updates the
existing Stormwater Master Plan and the Floodplain Management Plan and is one of the
components required by the Community Rating System (CRS) in order to maintain and
obtain additional credit for the 5-year CRS Cycle Recertification.
The purpose of the Stormwater Master and Floodplain Management Plan Updates are to
meet regulatory requirements, identify problem areas and issues relating to repetitive
loss properties, to identify and evaluate improvement alternatives, and to estimate costs
associated with various improvements to the stormwater management systems.
Updating the Stormwater Master and Floodplain Management plans also assists the
Village of Key Biscayne in maintaining the Class 7 rating compliance with the
requirements of the National Flood Insurance Program (NFIP) CRS program.
Tasks conducted as part of this project include:
• Data collection
• Existing stormwater infrastructure inventory
• Preparation if a geographic information system (GIS) to serve as a platform for the
existing and future stormwater infrastructure
• Preparation of a stomwater atlas based on the GIS platform
• Preparation of a hydraulic/hydrologic model of the Village’s stormwater system
• Identification of existing and future levels of service (LOS) based on water level
rises for varying stormwater conditions
• Preparation of cost estimates for various alternatives
• Prioritization of future improvements
• Identification of phased capital improvements
• Preliminary design of recommended alternatives
• Funding requirements and coordination with the stormwater rate study
