City
of Edgewater Stormwater Master Plan
The
City of Edgewater experienced structural and localized flooding following
above average rainfall in 1994 from Tropical Storm Gordon, during late
1997 and early 1998 due to effects of El Niño, and during late 1999 after
Hurricanes Floyd and Irene and Tropical Storm Harvey passed close to the
coast. Water levels in the primary drainage canals rose to maximum
historical levels causing street flooding, yard flooding, and in some
cases, structural flooding of buildings and other structures.
In
an effort to better address flood protection for its residents, the City
of Edgewater contracted with PEC/Professional Engineering Consultants to
prepare a comprehensive stormwater management plan. In addition to
funding by the City of Edgewater, financial contributions were also made
by the City of New Smyrna Beach, Volusia County and the St. Johns River Water
Management District.
Among
many other tasks, PEC was responsible for performing comprehensive
stormwater modeling of the Gabordy Canal Watershed (6,117 acres), the 18th
Street Canal Watershed (2,233 acres) and the Silver Palm Canal Watershed
(507 acres) using ICPR. The modeling effort was, in many respects,
quite challenging due to the flat topography
with multiple overtopping and cross connection possibilities and many long canals with numerous roadway
culverts. There were also 3 separate outfalls (i.e., boundary
conditions) for the Gabordy Canal Watershed, namely: (1) the
Intracoastal Waterway (North Indian River); (2) Turnbull
Creek; and, (3) Turnbull Hammock.
With
regard to the ICPR modeling effort, the Stormwater Master Plan included
the following assignments:
-
Existing
conditions analysis (view
partial
nodal network)
-
Delineation
of the 100-year flood elevations and associated special flood hazard
areas in support of a future FEMA LOMR application (example
water surface profile)
-
Analysis
of retrofit improvements associated with recommended capital
improvement projects
