Drainage Improvements Phase 111
RESOLUTION:
A RESOLUTION OF THE MAYOR AND CITY COMMISSION OF THE CITY OF
SOUTH MIAMI, FLORIDA, AUTHORIZING THE CITY MANAGER TO ISSUE A
PROFESSIONAL SERVICE WORK ORDER TO CORZO CASTELLA CARBALLO
THOMPSON SALMAN, P.A. (C3TS) FOR SURVEYING & TESTING, FINAL DESIGN,
BID AND CONSTRUCTION PHASE SERVICES FOR CITYWIDE DRAINAGE
IMPROVEMENTS PHASE III (SW 62 "D TERRACE FROM SW 62 "D AVENUE TO SW
60'x' AVENUE, SW 63RD STREET FROM SW 62 "D AVENUE TO SW 60TH AVENUE,
SW 63RD TERRACE FROM SW 62 "D AVENUE TO SW 60TH AVENUE AND SW 7e
TERRACE AT CUL -DE -SAC EAST OF SW 5e AVENUE) IN THE AMOUNT OF
$38,906.00 TO BE CHARGED TO PUBLIC WORKS DEPARTMENT ACCOUNT
NUMBER 111- 1730 - 541 -6490; PROVIDING AN EFFECTIVE DATE
BACKGROUND & ANALYSIS:
In the mid 1990's, Miami -Dade County completed roadway and drainage improvements
in the proposed project area, which includes:
• SW 62nd Terrace (from SW 62nd Avenue to SW 6& Avenue)
• SW 63`d Street (from SW 62nd Avenue to SW 6& Avenue)
• SW 63`d Terrace (from SW 62nd Avenue to SW 6& Avenue)
Since the completion of these improvements, residents have been reporting recurring
street, sidewalk and front yard flooding problems. Attached are pictures taken along
two of the streets in July, minutes following a rain event. In response to the flooding
problems, we asked C3TS to investigate the drainage problem. A complete copy of the
investigation report is attached. The result of the investigation revealed that the design
of the drainage system for the streets was substandard and that redevelopment in the
area, since the improvements, may have added to the problem by creating additional
impervious areas draining into the street. To correct the problem, it is recommended to
replace and increase the drainage system in the area.
As one of the City's professional general engineering consultants, C3TS will provide
survey & testing services, design, bid and construction phase professional services for
drainage improvements along SW 62nd Terrace (from SW 62nd Avenue to SW 60'h

1. INTRODUCTION
In the mid 1990's, Miami -Dade County completed roadway and drainage improvements
in the area of South Miami which includes the roadway segments that are the subject of
this investigations Since the completion of_. these_! mprovements , - residents __have-- been_-
reporting recurring street, sidewalk and front yard flooding problems. In response to the
flooding complaints, the City of South Miami commissioned C3TS to investigate the
nature and extent of the flooding problems and their apparent causes, and to study
potential remedial measures and their costs.
The services performed by C3TS are consistent with the level of care and skill ordinarily
exercised by members of the engineering profession currently practicing under similar
circumstances and location. No other warranty, expressed or implied, is herewith made.
The report presented herein complies with the applicable minimum standards and
practices of the profession.
11. INVESTIGATION AND FINDINGS
The area of S.W. 62nd Terrace, S.W. 63rd Street and S.W. 63rd Terrace is a residential
neighborhood composed primarily of small single family homes. There are also a few
multi - family developments, the largest of which is an apartment complex that fronts both
S.W. 62 "d Terrace and S.W. 63rd Street, from S.W. 62nd Avenue to approximately mid -
block between 62nd Avenue and S.W. 60th Avenue. The area slopes generally from a
low point just east of S.W. 62nd Avenue up to S.W. 60th Avenue (See figure 1).
Prior to investigating site- specific grading and drainage issues, we examined the general
nature of this area, in order to determine if the area lies within a zone noted to be prone
or vulnerable to flooding, based on available mapped data. This type of data would tend
to indicate whether the reported flooding is part of a greater problem, or more of a
discreet condition.
Figures 2 and 3 are the Dade County maps of October Ground Water Levels and of
Flood Criteria elevations, respectively. The first map represents the expected average
October ground water elevation. An elevation of 3.0 ft. NGVD is shown for this area.
The second map represents the flood level which is expected to be produced by the 10
year frequency storm. An elevation of 6.9 ft. NGVD is shown for the study area.
Figure 4 is the FEMA Flood Insurance Rate Map, which shows the area to lie within a
Zone X with a flood elevation of 9.0 ft. A Zone X is designated as an area not subject to
flooding during the 100 year frequency flood, with a flood level as indicated at 9.0 ft..
NGVD.
Based on the foregoing, and given the general elevations In the area, it can be inferred
that high ground water is not a problem. It could also be inferred that, with road crown
elevations no lower than 10 ft., the general area would not normally be subject to
flooding. From the evidence gathered from the mapped data, it can be concluded that
1929 -24.01
Corzo Castella Carballo Thompson Salman, P.A.
Investigation of Drainage
South Miami, Florida
the flooding of streets, sidewalks and front yards being experienced and reported by the
residents does not appear to be part of a larger area -wide problem, and in order to
understand the problem, site - specific grading and drainage systems must be
considered.
As previously reviously noted, the three roadways (S.W. 62nd Terrace, S.W. 63`d Street and S.W.
63 rTerrace) slope longitudinally down from S.W. 62nd Avenue to a low point just east of
S.W. 62nd, and then up to S.W. 60th Avenue. On each street, there is an intermediate
low point -which creatas-an upper catchment- area encompassing roughly the eastern - -
one -third of the roadway segments. The remaining two - thirds flows towards the
roadway low points near S.W. 62nd Avenue (See Figure 5). Each roadway catchment
area drains into a pair of curb inlet catch basins as illustrated below:
Drains on S.W. 62nd Terrace just east of S. W. 62nd Avenue
The catch basins pairs are connected to each other across the road by a closed pipe
segment, and to exfiltration trenches extending east and west from one of the catch
basins. The construction plans for these systems were not available, but based on the
fact that no terminal manholes exist either to the east or to the west of the catch basins,
it can be inferred that the trenches do exceed 50 feet each in length under Miami -Dade
County criteria.
Anecdotal evidence from residents of the area indicates that the reported flooding is
limited to the lower catchment areas and is particularly severe along .S.W. 62nd Terrace
and S.W. 63`d Street. The worst flooding was reported on S.W. 63`d Street. With each
heavy rainfall event, the flooding reportedly extends from the low point near S.W. 62nd
Avenue eastward for approximately 100 to 200 feet, and reaching a maximum depth of
approximately 8 to 12 inches at the low points. The flooding reportedly does not persist,
draining down within a few hours of the rainfall. According to resident complaints, the
flooding is not a recent phenomenon, but has occurred since the drainage systems were
installed along the roadway improvements project. It is unclear whether the severity of
the flooding has worsened over time.

These drainage systems are closed systems, with no outfall to either a water body or a
larger conveyance. As such, their ability to operate effectively and provide adequate
drainage depends on a variety of factors which can be generalized as follows:
Design
The design of the drainage system (exfiltration trench sizing) must account for all
areas being drained, the impervious coverage of these areas, for local
underground-hydro geologic conditions as well -as ground-water-table elevations.
The design of the drainage structures themselves is also important to allow for
serviceability and maintenance.
Maintenance
Maintenance includes sweeping of gutters to minimize the amount of vegetation
and debris entering the catch basins, cleaning of catch basins sumps to avoid
heavy accumulations leading to excess debris entering the exfiltration trench.
Maintenance could also include jetvac cleaning of the trench perforated pipe.
When exfiltration trench systems begin to exhibit problems draining, the lack of proper
maintenance is often found to be the cause of the problem. The useful service life of an
exfiltration trench system can vary significantly depending on the debris load entering the
trench. In areas with extensive tree canopy, leaves are a constant maintenance concern. If not
properly and consistently addressed, debris accumulation in the trench can lead to irreversible
trench clogging. The typical tree coverage on the three streets which are the subject of this
investigation can be seen below.

As can be seen in the photos, the tree canopy on S.W. 63rd Street is significantly greater
than the canopy along the other two streets, which may explain why the worst flooding
has been reported on this street.
The visible elements of the drainage systems were evaluated in the field to assess their
condition. The following observations were made:
• No accumulation of debris in the street gutters was noted.
• The catch basins all have sumps. No significant accumulation of debris was
noted in the catch basin sumps at the time of inspection. The photograph below
illustrates the typical conditions found.

• Some debris (mainly leaf litter) was noted in the bottoms of all of the exfiltration
trench pipe openings at the catch basins, as shown below.
The conditions noted above seem to indicate that the systems are currently being
maintained properly. However, there is some anecdotal evidence that this has not
always been the case. Figure 6 is an inlet condition assessment of one of these
drainage structures, which was performed in November 1996, as part of a citywide
drainage system inventory. That assessment reported the catch basin to be filled with
leaves to the point where the pipes into the exfiltration trenches were not visible. The
structure in question is the one which drains the worst reported flooding area on S.W.
63`d Street.
It seems reasonable to assume that although current maintenance practices seem to be
adequate, maintenance in the past was not being performed in an adequate or
consistent manner. Based on the debris noted in the trench pipe, and on the information
in Figure 6, it appears Likely that debris flowing into the trenches over many years has
degraded the capacity of these exfiltration systems.
Before concluding that poor past maintenance practices are the sole cause of the
flooding problems, the design of the exfiltration trenches must also be examined. Also,
conditions within the drainage area must be assessed to determine if significant changes
have occurred in land use or development which could have adversely affected the
systems after they were constructed.
As previously noted, the construction plans, details and calculations for the drainage
systems were not available, so certain assumptions will need to be made in order to
perform an analysis.
Design rainfall will be standard 5 yr. 1 hour storm = 3.2 inches.

• The total exfiltration trench length for the system draining each street's lower
catchment area will be assumed to be 100 feet (See prior discussion).
• The trench width and depth will be assumed to be a standard 4 feet and 15 feet,
respectively.
• The hydraulic conductivity (k) value will be assumed to be 1.8 x 10 -4 cfs /fe per ft.
head, based on a recently tested value a few blocks away (See figure 7).
• A safety factor of 2.0 will be utilized per SFWMD criteria.
• The drainage catchment area will be assumed to be the width of the right -of -way
plus 25 feet of front yards on either side. The large multi- family development
between S.W. 62nd Terrace and S.W. 63'd Street will be assumed to be draining
their 25 ft. front yards plus half of their roof area, for a total of 50 feet, into the
system. The picture below illustrates the condition of this development's
frontage, where the front yards are highly impervious (mostly pavers) and slope
towards the street. Half of the building roofs drain onto this paver courtyard as
well. The largest drainage area is that of S.W. 63rd Street, with a total area of
1.10 acres. The runoff coefficient (C) for this area was estimated to be 0.70 (See
figure 5).
Calculating the required trench length based on the SFWMD equation yields a length of
140 feet (See figure 8).
Based on the conditions noted in the field, and on the analysis detailed above, the cause of the
flooding appears to be the result of a combination of factors:
• The design of the exfiltration trenches, especially on S.W. 63rd Street, seems to be
substandard.

• Redevelopment in the area may have added to the problem by creating additional
impervious area draining into the street.
• Past maintenance practices appear to have been inadequate and inconsistent. This lack
of maintenance appears to have caused irreversible damage to the trenches.
RECOMMENDATIONS
The exfiltration trenches draining the lower catchment areas on S.W. 62nd Terrace and
S.W. 63rd Street clearly are not performing adequately. It is improbable that exfiltration
tenches in these conditions can be rehabilitated to an adequate serviceability. Even in
the unlikely event that they could be significantly improved by intensive jetvac cleaning, it
appears that their design is substandard and would still not meet the areas full drainage
needs. At over 10 years old, and having been marginally designed and inadequately
maintained, the trenches have reached the end of their useful service life, and need to
be replaced. The exfiltration trench on S.W. 63`d Terrace appears to be in somewhat
better condition, but should also be replaced since it is subject to the same conditions
which led to the failure of the other two.
The replacement trenches should each be 140 feet in length to provide a full 2.0 design
safety factor. The best location for the installation of the trenches would seem to be in
the pavement area, and would connect to the existing pipe between the catch basins on
either side of the street. Figure 9 is a conceptual layout of the recommended
improvements. These improvements include jetvac cleaning of the existing trenches, to
remove accumulations within trench pipes and allow these trenches to continue to
operate, even in their degraded condition. The estimated cost of construction for the
improvements is detailed below:

Permeability test was performed by drilling the test hole to a depth of 15 feet. Water was added to
the test hole at an average stabilized rate of approximately 8.0 gallons per minute (gpm) for a period
of 15 minutes in order to maintain a constant head at the ground surface level. The Hydraulic
Conductivity was calculated as follows
Q = Average Stabilized Rate: 8.0 gpm
H = Depth to Ground Water Level: 5 ft.
