Agenda 05/10/2011 Item #16A10
5/10/2011 Item 16.A.10.
EXECUTIVE SUMMARY
Recommendation to declare a valid public emergency and direct the County Manager or designee
to proceed with a re-evaluation of the FEMA-designated floodplain using the 2010 LiDAR and
approve all necessary budget amendments. (Fiscal impact $400,250)
OBJECTIVE: To protect, in an expeditious manner, the interests of property owners within a
portion of the floodplain identified by the Federal Emergency Management Agency (FEMA).
CONSIDERATIONS: On July 12,2010, FEMA released the Preliminary Digital Flood Insurance
Rate Map (DFIRM) for Collier County. The multi-year effort to produce the Preliminary
DFIRM was primarily through Tomasello Consulting Engineers, Inc. (TCE), working for both
Collier County and the City of Naples under two different, but related, contracts. During the 90-
day period oftime for submitting comments. protests and appeals to the Preliminary DFIRM, the
County amended its contract with TCE to prepare an appeal based upon the use of new LiDAR
topographic mapping that was obtained in early 2010. However, due to the 90-day time
constraint, TCE was only able to prepare an appeal for two basins out of the twelve plus a coastal
analysis included within the Preliminary DFIRM study area. While the final outcome of the
County's appeal is still uncertain during FEMA's review, the results looked favorable in
demonstrating the impacts of changed ground elevations.
,-
During the March 8, 2011 Board of County Commissioners (Board) meeting discussion on
adopting a new Flood Damage Prevention Ordinance (Agenda Item 8A) direction was given to
the County Manager to bring back a proposal to amend the floodplain maps for the remaining ten
basins and to provide a funding source to allow for payment of that project at this time. While
not specifically so stated in the approved motion, the County Manager understands the direction
is to also include the coastal flooding re-analysis.
.~
Growth Management Division staff discussed the floodplain re-analysis project with the
Purchasing Department staff and Director to determine the course of action to proceed. The type
of work falls within the requirements of the Consultants' Competitive Negotiation Act (CCNA)
identified in Chapter 287.055 of the Florida Statutes (F.S.). The anticipated cost to complete the
project exceeds the exemption threshold limits identified in Chapter 287.017 F.S. The
determination of the Purchasing Department was that this project required a competitive
selection and negotiation through the release of an RFP unless the Board detennines that a valid
public emergency exists. Based upon the requirements for public noticing, time to evaluate all
received proposals, short listing of the qualified respondents. Board approval of the shOlt listing,
negotiation of a contract with the selected firm, and approval of the contract by the Board, it is
anticipated that approximately 4 to 6 months will pass before a selected consultant can begin to
work on the project. By working with a new consultant, the estimated time to complete the work
and submit to FEMA's national service provider (currently Michael Baker Jr., Inc.) is 18 to 24
months. FEMA's review of the submitted re-analysis and the typical requests for additional
information or revision, along with FEMA's time to finalize the work product into a revised
Preliminary DFIRM for public comment, protest and appeal can be anticipated to take
approximately 12 months or more. The Preliminary Post-processing takes approximately 6

months unless there are extensive appeals to consider. Overall, the project is anticipated to take
at least 42 to 48 months.

Chapter 287.055 F.S. allows for exclusion from the provisions of competitive selection and
negotiation in cases of valid public emergencies certified by the agency head. If the Board
determines there is a valid public emergency, the County could amend the existing contract with
TCE and promptly proceed with preparing the appropriate analyses and mapping for submittal to
FEMA. The advantages of using TCE to perform this work are
. familiarity with the current floodplain mapping,
. possession of the existing modeling for coastal and inland basins,
. the re-analysis would basically be a repeat of the current work product using the updated
LiDAR topography,
. Michael Baker, Jr., Inc. staff is familiar with TeE's modeling approach and map
deliverables, and
. time and cost savings.
TCE is already under contract for the current Preliminary DFIRM appeal, and it can immediately
begin work on re-evaluating selected top priority basins where staff estimates the greatest
potential for flood insurance cost savings may occur due to development patterns and intensity.
Being a small, specialty firn1, it can only handle the workload of two or three basins at a time,
but as those basins are completed they can be submitted incrementally to FEMA. This would
create a rolling physical map revision process with all basin submittals completed within the
same 18 to 24 month time frame. From FEMA's position, it is better to receive map revisions in
adjacent basins to minimize the number of map panels being changed more than once. TCE has
already provided staff with a preliminary cost estimate of approximately' $400,000 for all of the
work. Overall, the project would be anticipated to take at least 30 to 36 months. A change order
for the TCE contract is attached to this executive summary demonstrating its proposed cost and
ability to immediately initiate work on the re-evaluation upon Board approval.

There is an urgency to complete the work when considering the financial impacts from flood
insurance purchase requirements. In the County's appeal of the Preliminary DFIRM based upon
use of the 2010 LiDAR, it was detennined there could be thousands of properties placed in a
Packet Page ~587~
5/10/2011 Item 16.A.10.
flood zone "X" instead of the flood zone "AH" as shown on the Preliminary DFIRM. This flood
zone difference is based upon the placement of fill for new developments that occurred between
the years when the two LiDAR products were flown, as well as a better resolution and reliability
of the elevation infonnation with the 2010 LiDAR. Notably, the 2003 LiDAR was flown in
2001 and the 2010 LiDAR was flown in 2008. In preparing the analysis for the Preliminary
DFIRM, only the 2003 LiDAR was available.
Staff is requesting the Board to determine there is a valid public emergency to support the
issuance of a change order and the continuation of the current contract with TCE to meet the
previously discussed time constraints and potential financial impacts to County property owners.
Continuity of computer modeling is a very important consideration for the ten additional basins
to align with the two basins submitted as an appeal of the Preliminary DFlRM. The model is a
proprietary model developed by TCE, and although it will be released to FEMA upon
finalization of the DF1RM, there can be a steep learning curve for another finn to begin using it.
Should another finn propose to use different but equivalent modeling software, there would be a
significant loss of time to rebuild and calibrate the model to FEMA's satisfaction. The
development of the coastal and inland floodwater interface analysis would also need to be re-
created and the results reviewed and approved by FEMA. All of this effort and approval takes
time, and time is money to local property owners who may be found to have structures located
within flood zone "X'. in the re-evaluation instead of in a flood zone "AH" on the Preliminary
DFIRM. Additionally, the cost estimate for TCE is knO\\TI, whereas staff can only estimate what
another firm may require through contract negotiations.
Staff has looked at areas of significant development between 2001 and 2008 in both the north
and southeast urban regions ofthe County. There appear to be thousands of building sites within
approved developments where lakes were excavated and fill placed for building construction. ln
east Naples, portions of the LAS1P have now been completed and can be added into the
computer modeling, although much of that area is predominantly affected by coastal surge
flooding.
When the County's appeal of the Preliminary DFIRM was submitted. staff estimated the
potential cost savings to property owners of approximately 23.000 structures within those two
basins at approximately $4.8 million just by not having to obtain an elevation certificate and file
for a Letter of Map Amendment (LaMA). Since this proposed work is outside of the
Preliminary DF1RM appeal pcriod and will be submitted as physical map revisions. there is no
assurance that FEMA will further delay finalization of the DF1RM. and property owners may be
faced with requirements for tlood insurance purchase or following through with the LOMA
process. Staff can keep FEMA notified of the upcoming map revision submittals to keep open
the possibility of including as many of them as possible into the DFIRM before it is tinalized by
issuance of FEMA's Letter of Final Determination. However. as the re-analysis is completed
and physical map revisions are submitted to FEMA for the various basins. there will be the
potential to identify many buildings within flood zone ,'x" and thus remove thc continued
requirement for flood insurance purchase. That cost savings can potentially be in the millions of
dollars per year. both by owners choosing to not purchase tlood insurance. or having the ability
to purchase flood insurance at a reduced rate as a preferred risk discounted policy.

FISCAL IMP ACT: Since this project has a direct benefit to and impacts all areas of Collier County
including the incorporated municipalities, funding for the change order would come from the General
Fund. Funding for FY2011 would require a budget amendment reducing General Fund reserves by
$400,250 consistent with the change order and transferring these dollars to Growth Management Division
Capital Fund (310) where the appropriation would be set up due to multi~year nature of the project. If the
project is approved by the Board, it is recommended that the initial FY2011 appropriation be established
and further that the project status be evaluated regularly and if additional funding is required, Board
action would be sought.
LEGAL CONSIDERATIONS: This item has been reviewed and approved by the County
Attorney's office, is legally sufficient for Board action, and only requires majority vote for Board
approval. -SRT
GROWTH MANAGEMENT IMPACT: None
RECOMMENDATION: That the Board of County Commissioners:
Detemline there is sufficient justification to declare a valid public emergency, and:
. Direct the County Manager or his designee to finalize the change order with Tomasello
Consulting Engineers, Inc. to prepare the re-analysis of the floodplain for the 10 basins
outside the area of the County's Preliminary DF1RM appeal plus a re-analysis of the
coastal flooding,
. Authorize the Chairnlan to sign the change order; and
. Direct the County Manager or his designee to prepare the necessary budget amendment
to fund this change order.
