PROJECT DESCRIPTION / SCOPE OF WORK:

MDX C-4 BLUE LAGOON XP SWMM Modeling Analysis

Hired to assist on a permitting effort to perform xp swmm modeling. We created a volumetric analysis report utilizing Miami-Dade County Department of Environmental Resource Management (DERM) C-4 existing and future conditions models for the 5, 10, 25, 50 and 100 year storm events.  Widening of the 836 off-ramp close to Miami-Dade International Airport (MIA) required the Miami-Dade County Expressway Authority (MDX) to propose filling in a portion of the adjacent Blue Lagoon.  A total of four scenarios were analyzed including (1) Current conditions. (2) MDX filling in 6 Acres within their right-of-way. (3) MDX filling in all of their right-of-way, or roughly 25 Acres, and finally. (4) a cumulative scenario of all properties who would have fill rights including MDX to fill in the lagoon within their property boundaries requested by Carlos DeRojas, P.E. and Eduardo Lopez, P.E., who work with SFWMD Surface Water Regulation Department in West Palm Beach, FL.  A comparison of hydrographs and tabular results was reported for all 40 xp swmm modeling runs and a final conclusion of a negligible flood stage impact to the C-4 Basin’s critical nodes was provided. Some critical nodes examined include the Cities of Sweetwater and Doral located just west of Miami, Florida. XP SWMM Modeling is the preferred model for all Miami-Dade County projects and is the model of choice by the Water Control section of Miami-Dade County DERM. XP swmm modeling was developed in Australia and is used around the world,
