S W 34th Terrace Stormwater Improvement (Project) is a proposed dewatering
operation located along SW 35th Ave, on the north side of Griffin Road, in Broward
County, as shown on Exhibits 1 and 2. Dewatering is necessary to facilitate installation
of drainage pipe and associated maintenance access structures along an existing
roadway. The method of dewatering is to be accomplished via wellpoint system.
Dewatering effluent will be discharged off-site to the SFWMD Dania Cut-Off Canal
bounding the Project from the north, west, and east. Pump specifications are shown on
Exhibit 3 and dewatering plans and calculations are shown on Exhibit 4. The maximum
extent of dewatering will be to a groundwater elevation of -5.05 feet North American
Vertical Datum (NAVD), which is approximately 7.24 feet below the average land
surface elevation of 2.19 feet NAVD. The anticipated duration necessary to complete all

dewatering activities is 180 days. The maximum daily pumpage is estimated to be 0.66
million gallons (MG) and the total Project pumpage is not expected to exceed 118.59
MG. Turbidity monitoring will be conducted daily to ensure turbidity levels are less than
29 nephelometric turbidity units (NTUs) above background levels. If monitoring indicates
that state water quality standards are not being maintained, the dewatering operation
shall cease until monitoring demonstrates that water quality standards are met. Turbidity
records will be maintained on-site for District staff review.
If exceptional storm conditions occur that exceed the capacity of the dewatering effluent
disposal systems, the Permittee is required to cease dewatering operations until
adequate storage is available to contain all dewatering discharge.
At least 72 hours prior to initial dewatering, the Permittee shall notify
wucompliance@sfwmd.gov that dewatering is about to commence. A copy of the permit,
its limiting conditions, and dewatering plan is required to be kept on site at all times
during dewatering operations by the lead contractor or site manager. The Permittee is
advised that this permit does not relieve any person from the requirement to obtain all
necessary federal, state, local and special district authorizations.
Pursuant to Special Permit Condition 3, dewatering is authorized by this permit for a
duration of one year from the start date provided to the District by the Permittee in
accordance with the notification requirements as stated in the Special Conditions of this
permit.
Wetland Environments:
The nearest wetland areas are located at least 1,600 feet west and north of the Project
site; however, those wetlands are hydrologically connected to the multiple surrounding
canals, and the estimated radius of influence will not extend to the wetland areas.
Dewatering effluent will be discharged to an adjacent residential canal, which is directly
connected to the Dania Cut-Off Canal. Turbidity curtains will be placed at the outfall into
the canal, and a turbidity monitoring plan will be required during the dewatering
activities. Based upon application of the narrative standard that the hydrologic alteration
of the water use shall not adversely impact the values of wetland functions so as to
cause harm to the abundance, diversity and habitat of fish, wildlife and listed species,
the potential for harm to occur to the off-site wetlands as a result of the dewatering
operations is considered minimal.
Migration of Saline Water:
The Project is located within close proximity to the Dania Cut Off Canal. Groundwater is
likely to be saline and tidally influenced beneath this Project. Considering the
dewatering is localized and temporary, the potential for this dewatering to incur further
saltwater intrusion or upconing is minimal.

STANDARD PERMIT CONDITIONS
All water uses authorized by this permit shall be implemented as conditioned by this
permit, including any documents incorporated by reference in a permit condition. The
District may revoke this permit, in whole or in part, or take enforcement action, pursuant
to Section 373.136 or 373.243, F.S., unless a permit modification has been obtained to
address the noncompliance.
The Permittee shall immediately notify the District in writing of any previously submitted
material information that is later discovered to be inaccurate.
The Permittee is advised that this permit does not relieve any person from the
requirement to obtain all necessary federal, state, local and special district
authorizations.
The Permittee shall notify the District in writing within 30 days of any sale, transfer, or
conveyance of ownership or any other loss of permitted legal control of the Project and/or
related facilities from which the permitted consumptive use is made. Where Permittee's
control of the land subject to the permit was demonstrated through a lease, the Permittee
must either submit a new or modified lease showing that it continues to have legal
control or documentation showing a transfer in control of the permitted system/project to
the new landowner or new lessee. All transfers of ownership are subject to the
requirements of Rule 40E-1.6107, F.A.C. Alternatively, the Permittee may surrender the
consumptive use permit to the District, thereby relinquishing the right to conduct any
activities under the permit.
Nothing in this permit should be construed to limit the authority of the District to declare a
water shortage and issue orders pursuant to Chapter 373, F.S. In the event of a declared
water shortage, the Permittee must adhere to the water shortage restrictions, as
specified by the District. The Permittee is advised that during a water shortage, reports
shall be submitted as required by District rule or order. The Permittee is advised that
during a water shortage, pumpage, water levels, and water quality data shall be collected
and submitted as required by District orders issued pursuant to Chapter 40E-21, F.A.C.
This permit does not convey to the Permittee any property rights or privileges other than
those specified herein, nor relieve the permittee from complying with any applicable local
government, state, or federal law, rule, or ordinance.
With advance notice to the Permittee, District staff with proper identification shall have
permission to enter, inspect, observe, collect samples, and take measurements of

Project Description
The City of Dania Beach’s Stormwater Improvements along SW 34th Terrace involves the installation of
approximately 1,500 linear feet of drainage pipe and associated maintenance access structures (MASs).
Please refer to “SW 34th Terrace Stormwater Improvements” map. The Stormwater Improvement Project
is bounded by Griffin Road to the south, and dead-ends at the cul-de-sac of SW 34th Terrace to the north.
The static water table in the area varies seasonally approximately 3.5 feet below the surface (see Boring
Logs by PanGeo Consultants). A conservative water table elevation vale of 1.50 NAVD was used for
computational purposes. Most of the new stormwater pipe invert elevations are below 0.0 NAVD.
Consequently, short term dewatering, using well-points, will be necessary to ensure that the Maintenance
Access Structures (MASs) and the deeper piping runs are assembled in-the-dry under safe and stable
conditions. Chen Moore & Associates prepared a SFWMD General Mining/Dewatering Permit Application
in accordance with the District’s Basis of Review Manual.
Trench Dewatering Description
Trench Dewatering will be required for the majority of the new Stormwater drainage piping runs. Please
refer to the Stormwater Improvement Design Plans, for the rim elevations and stormwater drainage pipe
invert elevations at Maintenance Access Structures (MASs). For Computational purposes it was assumed
that any piping run with an invert elevation below +1.00 NAVD will require well-point dewatering. Trench
dewatering will be accomplished in 200- or 300-foot increments depending on the trench depth. Well-
points will be spaced at approximately 12-foot intervals. The swing connection from the well-point riser
to the header pipe will include a flexible suction hose, a disconnect union and an adjusting cock (control
valve) for tuning. A flow meter will be installed on the pump’s discharge line. The expected duration of
the dewatering is six months.
Turbidity Monitoring Plan
The dewatering water will be discharged to the SFWMD Dania Beach Cut Off Canal. A floating turbidity
curtain will be placed during dewatering procedures at dewatering discharge point. Turbidity
Measurements of the effluent shall be made daily at the point of discharge and a background condition
(upstream) in the receiving water body. Please see draft dewatering plan map with location of dewatering
discharge point and planned monitoring locations. If turbidity levels in the effluent exceed 10 NTU above
background conditions of the received water body the is required to correct Permittee is required to
correct the situation and cease dewatering operations until monitoring demonstrated turbidity meet the
requirements of Chapter 27-195 and 27-196 BCC. All dewatering activities will cease during a storm or
major rain event.
Permittee shall comply with turbidity and general water quality standards for surface discharge into
receiving streams, as established by Chapter 62-302, Florida Administration Code.

Radius of Influence Calculations
The Sichart empirical equation (Powers, J.P., “Construction De-watering”, 2nd Edition, John Wiley & Sons,
Inc., 1992, page 104) was used to calculate the radii of influence (𝑅𝑜) from dewatering at the most 5
pertinent (critical) locations. Note that due to the relatively deep invert elevation most of the project
piping will required well-point pumping. Table 1 below presents a summary of the input data to the Sichart
equation:

The data in Table 1 was converted to metric and input to the following Sichart empirical equation:
in order to calculate an approximate radius of influence (R o ) from dewatering at each of the pertinent
MASs. To consider the rectangular area for the dewatering activities of the project, the radius of influence
is added to the equivalent radius of influence, (re ) calculated from the equation:

As shown in Table 2, the total radius of influence calculated are significantly less than the distance to the
closest contaminated site. Therefore, the District may be reasonably assured that the proposed
dewatering at SW 52nd St Stormwater Improvement Project will not cause any contamination plumes
existing at the site to mitigate.
The requisite flow rates were subsequently calculated. The “direct calculation” detailed in Exhibit III of the
Broward County Environmental Assessment and Remediation Section Standard Operating Procedure for
Dewatering was used to estimate the pumping rate required to maintain the desired de-watering depth:
