City Manager ENCLOSURES: (For Commission Meeting of
June 13. 1 985 )
i
The Department of Public Works recommends
the adoption of a resolution approving A
PROFESSIONAL SERVICES AGREEMENT TO
DEVELOP A COMPREHENSIVE STORM DRAINAGE
MASTER PLAN for the City; and authorizing
the City Manager to execute a negotiated
professional services agreement with
Priede-Sedgwick, Inc. on behalf of the
City.
Resolution No. 85-266 adopted on March 21, 1985 approved the rank
order of qualified firms by the Competitive Selection Committee and
authorized the City_Manager to negotiate a professional services
agreement with Priede-Sedgwick, Inc. A professional services
agreement has been successfully negotiated to the satisfaction of
both parties. It is now in order to present this agreement to the
City Commission for final approval and execution by the City Manager.
The negotiated fee for this service agreement is $158,000 with a
$25,000 Contingency for a total of $183,000. Funds for the project
are available in the Storm Sewer General Obligation Bond Fund
Account.
The appropriation for this project has been set at $350,000. The
additional funding above the $183,000 fee was included in order to
expand the pollution control study section of the master plan for
which the City had made a grant application through the State of
Florida Office of Coastal Management. This department was encouraged
to appropriate these funds when the City was informed that the grant
application was receiving strong support at several state committee
levels. However, it was recently learned that grant funds will not
be available this year for the project. It is strongly recommended
that these additional funds remain in the appropriations ordinance
since the City will reapply for grant funding next year.

PART 1 - HYDROLOGIC STUDY
Task �.1
AVAI CIMM-1 -11= -A2
An initial delineation of watershed districts has
already been developed by the CITY. The watershed
districts tributary to receiving waters as well as
those districts not tributary to receiving waters will
be further examined in terms of the soil
characteristics and their capacity to accept
stormwater, i.e., their exfiltration capacity. Based
on this analysis the watersheds will be further
subdivided as required into areas with homogeneous soil
characteristics. For each of these watersheds, the
following characteristics will be determined:
o Surface infiltration capacity,
Recharge capacity from exfiltration
drainage systems,
o Area presently drained by exfiltration
systems,
o Areas resentl drained b
p y y positive
drainage systems,
o Percent of the area that is impervious,
o The percent of impervious area that is
drained by positive systems,
o Ground slope of the watershed,
That portion of the watershed which is
a county or state road and whether the
drainage system is an exfiltration
system or a positive system.
Paige 1 of 5
cgs
1
t
These data will be Wised to determine the infiltration
oapaolty by watershed and to determine the surfaoe
Y . runoff resulting from historic and design atoms. The
CITY will furnish maps of the study area from whidh the
required data can be extracted. Any missing data will
be surveyed or otherwise obtained by the CITY. if
exfiltration tests are required, the CITY will be
responsible for conducting these tests at a limited
number of sites mutually agreed upon the CONSULTANT
and the CITY.
Task _1_.2 Determine Rainy Season Groundwater Levels
The CONSULTANT will review the 74-year rainfall record
at the Miami International Airport. In consultation
with City staff, a number of rainy season periods will
be selected for hydrologic analysis. Groundwater
levels within the City will be examined during the
relationship of seasonal rainfall to groundwater
levels. These data will be used to help determine
locations where exfiltration drainage systems can be
effectively used.
Groundwater level data collected by the CITY will be
provided to the CONSULTANT by the CITY.
Task 1.3 Determine Feasible Areas for Exfiltration Systems
The computer model STORM, developed by the CONSULTANT
will be used to simulate the exfiltration systems for
the City of Miami. The computer program will be
modified to relate exfiltration capacity to groundwater
level and antecedent precipitation.
STORM is a computer model that takes long term
hydrologic records on the basis of soil moisture
capacity, groundwater level and exfiltration capacity,
how much of the rainfall will be infiltrated into the
ground and how much will pond or be relieved by
positive system as exfiltration system overflows.
Page 2 of 5
.r
0
Tne model STORM will be used to estimate, for each
watershed di.striot, each flood event that occurs and
the magnitude of flooding for the event. Taking into
aceount exfiltration capacity, plus sizing of
Lhxfiltration overflows, and/or positive systems, this
information is then processed internally in the program
to develop a frequency curve. The flood magnitudes for
the 39 59 109 25, and 50 year events will be
determined. Based on these results, areas of the City
will be identified where (1) exfiltration systems can
be used exclusively, (2) exfiltration systems can be
used together with overflow relief and/or limited
positive systems and (3) positive drainage systems are
required.
Tas k1 u Determine Canal Capacities
For each of the flood frequencies analyzed in Task 1.3,
a determination will be made of the wet weather
e-apacity of Tamiami, Miami, Comfort, Little River, and
Sebold Canals. An estimate will also be made of the
capacity that can be allocated to the City by watershed
district for each recurrence interval. In order to
make this determination it will be necessary to use a
mathematical. model which can route flow hydrographs
through the City canal and river system and determine
the flows and water surface elevations through time.
The Environmental Protection Agency (EPA) SWMM model
and HEC-2 will be used for these determinations. The
analysis of flows and heads at various locations in the
canals/river systems will be used to determine those
locations where: (1) flooding in the canal occurs; and
(2) there is excess capacity.
The CONSULTANT will perform this analysis for three
conditions. The first condition is South Florida Water
Management District's (SFWMD) present operating policy
for the Tamiami and Comfort Canals. The second
condition is the increased water levels in these canals
as proposed by SFWMD. The third condition assumes that
SFWMD increases the levels of those canals but operates
the salt water barriers during wet weather periods in
such a way as to allow more flow through the canals.
These allocations of canal capacity will be used in
Master Plan Development for determining where the
outflow from the positive drainage system installed in
the various watershed districts can be discharged.
PART 2 - STORMWATER POLLUTION STUDY
Y
i
Using available data sources, the CONSULTANT will develop art
estimate of annual nonpoint pollution loadings from each
watershed district in the City. Loading projections will be
developed for existing and future land use patterns and for
the following pollutants: suspended solids, total
phosphorus, total nitrogen, biochemical oxygen demands
hydrocarbons, and selected heavy metals (lead, zinc, and
eopper). Annual discharges of each pollutant into the
following thee classes of receiving waters will be estimated:
(1) Tamiami, Miami, Little River, Seybold and Comfort canals;
(2) Biscayne Bay (direct discharges); and (3) groundwater
aquifers.
PART 3 MASTER PLAN DEVELOPMENT
Task 3.1 Test Positive Systems of Various Capacities
for Reducing Flooding
For those watershed districts determined in Task 1:3
which require positive drainage systems, the CONSULTANT
will determine the magnitude of flooding that occurs
from larger events if the positive system is sized to
handle runoff from the 3, 5, 10, and 25 year events,
respectively. Based upon analyses, the CITY wily
select a design frequency for each watershed or for the
City as a whole. The CONSULTANT will then size the
major components of the drainage system for each
watershed to provide flood protection for the specified
design storm event.
For watersheds containing state and county roads,
system sizing will include capacity as required for
excess runoff from these areas to provide the required
level of flood protection in the watershed.
Task 3.2 Cost Estimate for Systems
For each watershed district, an estimate of the cost to
improve the system to the desired level of protection
will be made. Both capital and operation and
maintenance costs will be identified. In addition, the
cost to handle runoff from county and state roads will
also be shown.
Page 4 of 5
L
FART 4 - FACILITIES HMOPMENT PROGRAM
The CONSULTANT will assist the CITY in developing criteria
for prioritizing drainage improvements in the City. Factors
to be considered include frequency of flooding, magnitude Of
flooding, cost or degree of inconvenience caused by flooding,
and cost per unit of protection gained. This criteria will
be used by the CONSULTANT to determine a priority list for
correction of flooding problems in the City.
FART 5 - DRAINAGE ORDINA14CE REVIEW
The CONSULTANT will review all existing city, county, state
legislation and criteria that relate to the design and
construction of drainage facilities in the City. In
consultation with the CITY'S legal staff, the CONSULTANT will
identify all state statutes and/or local ordinances which
relate to the CITY'S authority to (1) provide storm drainage
services and (2) levy charges to support them. A summary of
these statutes and ordinances will be presented.
This analysis will include a review of potential problems or
conflicts that have to be resolved in order to implement a
City-wide stormwater management program. The review will
also cover the definition of on -site stormwater drainage and
nonpoint pollution control requirements that are compatible
with the specifications of the South Florida Building Code,
a Policies of the City of Miami, Dade County Environmental
Resources Management (DERM), South Florida Water Management
3 District (SFWMD), the Florida Department of Environmental
Regulation (DER). This analysis must define all existing
permit requirements. The evaluation will assess the impacts
of the new NPDES discharge permit regulations for urban
runoff discharges which were promulgated in September 1985 by
the EPA.
