R7P-Retroactively Approve Additional Service Agreement With CDM-SmithCOMMISSION ITEM SUMMARY
Condensed Title:
A Resolution Of The Mayor And City Commission Of The City Of Miami Beach, Florida, Retroactively
Approving An Additional Service Agreement With COM-Smith For Work On The Stormwater
Management Master Plan Relative To Neighborhood Concurrency Reviews, A Public Meeting, And
Additional Madel Runs Requested As A Result Of That Meeting.
Key Intended Outcome Supported:
A well maintained infrastructure
Supporting Data (Surveys, Environmental Scan, etc.): Per the 2011 Strategic Plan update,
only 44% of residents and 45% of businesses rated storm drainage as excellent or good.
Item Summary/Recommendation:
At its June 9, 2010 meeting, the City Commission, via Resolution No. 2010-27422, authorized the
City's consultant, Camp Dresser & McKee (now COM Smith), to prepare a new Storm Water
Management Master Plan (SWMMP), and at its November 14, 2012 meeting, the City Commission,
via Resolution No. 2010-27422, adopted the SWMMP.
The consultant created a comprehensive, citywide model of the stormwater infrastructure, identified
those basins that are experiencing a reduced level of service, projected sea level rise in order to
provide minimum stormwater design criteria, and developed order of magnitude cost estimates for the
improvements.
Outside the base scope of services, the consultant used the model to provide concurrency reviews of
ten neighborhood improvement projects that prompted changes to the stormwater designs of the
neighborhoods due to inter-basin flows and resulted in improvements that will be more effective and
more flexible to account for the uncertainty relative to the rate of sea level rise.
At the June 28, 2012 Finance and Citywide Projects Committee meeting, the Committee directed staff
to have a public discussion on sea level rise and to return with the results, and this public discussion
was not included in the base scope of services.
As a result of questioning at the public discussion, the consultant calculated the additional cost of the
capital improvements for a 30-year time frame and presented an analysis of the costs differences
between a 20-year planning horizon and a 30-year planning horizon. The consultant and City staff
negotiated compensation based upon the work performed -paying for additional services (and not
additional work required to further explain or justify analyses conducted under the base scope of
services)-with a total cast of $57,804.
THE ADMINISTRATION RECOMMENDS ADOPTING THE RESOLUTION.

BACKGROUND
As a result of Request for Qualifications (RFQ) 03-09/10 and subsequent resolution 2010-
27334, the City Commission authorized the Administration to enter into negotiations with Camp
Dresser & McKee, the top-ranked firm responding to the RFQ.
At its June 9, 2010 meeting, the City Commission, via Resolution No. 2010-27422, authorized
Camp Dresser & McKee (now COM-Smith) to prepare a new Stormwater Management Master
Plan (SWMMP) in the amount of $1,091 ,435. At its November 14, 2012 meeting, the City
Commission, via Resolution No. 2010-27422, adopted the SWMMP (Attachment A is the
Executive Summary for the Plan).
Per the base scope of services, the consultant created a comprehensive, citywide model of the
stormwater infrastructure, identified those basins that are experiencing a reduced level of
service, projected sea level rise in order to provide minimum stormwater design criteria, and
developed order of magnitude cost estimates for the improvements, for which the consultant
has been fully compensated according to their initial contract as negotiated at that time.
ANALYSIS
Outside the base scope of services, the consultant used the model to provide concurrency
reviews of ten neighborhood improvement projects. These reviews prompted changes to the
stormwater designs of the neighborhoods due to inter-basin flows. As a result, the neighborhood

improvements will be more effective in providing the required LOS and more flexible to account
for the uncertainty relative to the rate of sea level rise.
At the June 28, 2012 Finance and Citywide Projects Committee, there was a technical
discussion on the existing mean high water and the rate of sea level rise. As a result, the
Committee directed staff to have a public discussion on sea level rise and to return with the
results. This public discussion was not included in the base scope of services.
This SWMMP Sea Level Rise Discussion was held on Friday, August 17, 2012. The
presentation (Attachment B) began with a discussion contrasting the City's previous SWMMP to
the new SWMMP. The presentation then focused on sea level rise and the reports and data
available to estimate mean high water and the rate of sea level rise. Following this, the
consultant discussed how sea level rise was incorporated into the draft SWMMP and into the
recommended capital improvements.
It was stressed that there is a large degree of uncertainty with the rate of sea level rise. As a
result, the City has developed a flexible capital improvement plan that can accommodate
various rates of sea level rise. The capital improvements will rely on backflow preventers at the
outfalls, more pump stations, raised seawalls, and stormwater storage. The City will need to
monitor the rate of sea level rise and adjust the plan accordingly. As sea level rises, the
stormwater system will rely more upon pumps, and as the existing pumps age, they will be
replaced with larger pumps.
The presentation was generally positive with acknowledgement that the City is in the forefront of
developing a capital program to address sea level rise projections. There were also some
concerns expressed about the SWMMP. It was questioned why the consultant developed a
master plan with a 20-year horizon instead of a 30-year or 50-year horizon. It was explained that
the life cycle of a pump is approximately 20 years. After 20 years, a pump that has reached the
end of its life cycle could be replaced with a larger pump depending on the rate of sea level rise.
The consultant calculated the additional cost of the capital improvements for a 30-year time
frame. While it requires larger pumps in certain locations, the 30-year time frame does not
change the requirements for catch basins, piping, and seawalls and the difference in cost was
$10 million. There were also questions about the ability of the City to deal with sea level rise
beyond the 20-year or 50-year horizons. It was stressed that the SWMMP provides flexibility
beyond the time horizons discussed.
At the August 22, 2012 Finance and Citywide Projects Committee, staff presented the results of
the Discussion (Attachment C) and an analysis of the costs differences between a 20-year
planning horizon and a 30-year planning horizon. The Committee approved the plan with the
recommendation to use a 20-year planning horizon and not the 30-year planning horizon. The
consultant has indicated that the work required for the presentation and required to develop a
30-year planning horizon was also outside the base scope of its services.
City staff has negotiated what it believes is fair and reasonable additional compensation based
upon the work performed: paying for additional services (but not paying for additional work
required to more fully explain or justify analyses conducted under the base scope of services).
Staff believes that it is appropriate to pay an additional:
