Sarasota - FEMA Map Modernization
31, 2010. The time extension has been approved. 2. Watershed Updates (BCI): The agreement with BCI was executed
on January 8, 2004 to conduct the scoping activity, and generate digital topographic information (DTI) via LiDAR for the
entire county. Notice to proceed (NTP) for Work Order (WO) #1 was issued effective January 15, 2004. WO#2 to
perform the scoping activity was executed on February 8, 2004; and NTP was issued effective January 15, 2004.
Delivery of DTI was delayed for well over a year. The delay impacted the schedules of all the other elements and
consultants contributing to this project. Project scoping was completed in August 2004. The First Amendment to BCI's
agreement was executed to include updates to the County's existing Dona/Roberts Bay and Lemon Bay watershed
models to reflect the new DTI, convert models from NAVD29 to NAVD88, and begin updating the Ainger and Forked
Creek models to the District's G&S. BCI completed the conversion for its assigned watersheds and deliverables were
received on January 23, 2006. The BCI Agreement was amended as of February 13, 2007 to extend the contract
termination date to January 8, 2008. BCI WO#4 was executed to allow BCI to complete remaining update tasks. Draft
models and associated GIS data for Curry Creek, Hatchet Creek, Alligator Branch, and the Island of Venice were
received on October 14, 2008. The submittal was reviewed by District staff, and comments were provided to BCI on
December 12, 2008. The $750,400 in FEMA funds encumbered to the agreement with BCI has been expended.
$587,281 in B206 funding is being used to completed the models, and the peer and public review process. 3. Watershed
Updates (JEA): Agreement JEA was executed and WO#1 issued to update the existing Little Sarasota and Sarasota
watershed model. JEA completed conversion of these models from NGVD29 to NAVD88. WO #2 was then executed to
begin the update of the Phillippi Creek watershed parameters and model to the District's G&S. Deliverables were
received in March 2007 and reviewed by District, County, and municipal staff. It was determined that significant revisions
were needed to address issues with the original model, and that the work cannot be completed in time to use for DFIRM
generation. Further updates to the Phillippi Creek model were postponed. The consultant services agreement with JEA
was amended to include floodway analyses and ArcHydro tool development to automate repetitive hydrologic and
hydraulic modeling tasks (M118). The First Amendment to JEA's agreement was executed on March 13, 2006. WO#3
was executed on May 16, 2006 for the conceptual design of ArcHydro tools. WO#4 was executed on May 8, 2007 to
develop the ArcHydro tool for Irregular Weirs. WOr #5 was executed to perform limited updates to the remaining
Sarasota Bay and Little Sarasota Bay models, and convert the lower Myakka River model to NAVD88. Draft deliverables
were submitted for WO #5. WO #6 was issued to update the Hudson and Whitaker Bayou models to reflect 2007 terrain
data and incorporate ERP information. Draft deliverables were received on November 3, 2008 and December 30, 2008
respectively. District and County review comments were provided to JEA on December 3, 2008 and February 5, 2009
respectively. $729,550 of the FEMA funds have been encumbered to the agreement with JEA, of which $673,575 has
been expended. $140,291 in B206 funding are being used to complete the models, and the peer and public review
process. 4. DFIRM Production (URS): The agreement with URS Southern was executed on January 15, 2004, to
produce the countywide Digital Flood Insurance Rate Maps (DFIRMs) and Flood Insurance Study (FIS), and to support
public outreach. The URS Agreement was amended twice, ultimately extending the contract expiration date from July 14,
2008 to June 1, 2010. WO #1 was executed on February 16, 2004 to identify the data to be used for DFIRM production,
and prepare a detailed approach and project outline. URS completed these tasks. WO #2 was executed to prepare the
base maps and perform outreach. URS submitted draft base maps and redelineations for review and approval in
February 2009. District, FEMA, County, and local government staff reviewed the information and provided comments to
URS in April 2009. Staff executed WO#3 with URS to incorporate the final deliverables from model updates and the Big
Slough WMPlan (K883) to produce the preliminary DFIRMs and FIS. A meeting/conference call was held on June 29,
2007 between all consultants associated with the project to coordinate schedules, review deliverable requirements, and
identify points of contact. URS was asked to stop work on production of the preliminary DFIRMs until model updates are
completed. On March 24, 2008 WO#3 was re-issued to reflect the work completed before the stop work order. NTP for
WO#4 was issued on June 5, 2008 for the preparation of the DFIRMs, DFIRM database, and FIS report using the
watershed models that are currently under development, and watershed models previously developed by the County.
Several of the County models have not been signed and sealed by a professional engineer. The County has retained
professional engineers to review and certify the models. The following County models have now been certified, and have
been provided to the URS to include on the draft maps: Lemon Bay, Cow Pen Slough, Phillippi Creek, Little Sarasota
Bay, Lower Myakka River, Upper Myakka/Howard Creek. $520,000 of the FEMA funds have been encumbered to the
agreement with URS, of which $278,000 has been expended. $110,597 in B206 funding has been added to the
agreement to cover the cost of incuding the County's certified models and participate in public meetings.
