4. Hurricane Ian Recovery& Status Update [Chris Mason]
Mr. Mason detailed a PowerPoint presentation:
• There have been 4,280 permits for Hurricane Ian applied for, including demolition, repairs,
single-and multifamily dwellings.
• The largest total is for single-family dwellings(682), followed by AC replacement(589),
electrical(358),and multifamily repairs(304). Cellphone towers(8)came in last.
• The Floodplain Management section was tasked with assisting the Federal Emergency
Management Agency(FEMA)and the Florida Division of Emergency Management(FDEM)
with temporary housing.
• Temporary housing units are comprised of mobile homes or travel trailers.
• There are provisions within the Code of Laws&Ordinances to place travel trailers for living
purposes on properties that have been damaged as a result of Hurricane Ian.
• The County has experienced difficulty with getting FEMA on board with temporary housing
requirements established by the County in its Code of Laws&Ordinances.
• In some cases,the FEMA-procured housing contractor placed temporary housing units on
properties without a permit. Staff has rectified these cases.
• There are about 35 temporary housing units on properties supplied by FEMA,FDEM and
private ownership units on properties today.
• A mobile home park on Radio Road put in four units.
• FEMA offers multifamily leasing and repair;transportable temporary housing units-trailers
or manufactured homes; and a direct lease for ready-to-occupy housing.
• FEMA has worked with property owners at the Jade(At Olde Naples)and Stillwater Cove
Apartments
• FDEM is running a parallel mission with travel trailers.They're working with Harmony
Shores Mobile Home Park(MHP)to secure space for further temporary housing.Harmony
Shores MHP will be able to support up to 60 units.
• Housing is in short supply.
• The county works with FDEM and FEMA weekly to ascertain housing needs: the weekly
meeting occurs every Thursday.
• The program lasts 24 months and ends in March 2024.
• After that time,FEMA reps will approach property owners to see if they would like to
purchase the travel trailer or the mobile home. If a homeowner buys a travel trailer, it could
only be a weekend getaway.
• If the trailers aren't purchased,they're auctioned off or sold back to FEMA.

5. 2022 Community Rating System Verification Cycle Completion Update
Mr. Mason told the FMPC:
• The Community Rating System is a subset of FEMA's NFIP.
• FEMA rewards municipalities with reduced premium rates.
• We've partnered with FEMA since 1992; there's a three-year verification cycle and three-
year audit.
• Communities are scored from 1-9 and Collier is scored at a Class 5,which provides a 25%
insurance discount, which means $8.3 million stays within the county.
• There are more than 60,000 flood-insurance policies here.
• Our three-year cycle wrapped up in February and we're still a Class 5,which is a challenge to
maintain.
• Collier County is No. 2 in Florida. Miami-Dade is No. 1 because they have 50.000 more
flood-insurance policies than we do.
Chairman Johnson asked if Naples and Marco Island are part of the CRS.
Mr. Mason said yes, both are Class 5 communities and have participated since 1992. Everglades City
joined last year and is a Class 9,with a 5%discount.
Mr. Mason continued his presentation:
• Each year, Floodplain Management staff completes the Elevation Certificate review with
Insurance Services Office(ISO), which are rated yearly.
• We submitted more than 1,200 to FEMA and they take a sample of 200. We're 100% in
compliance.
• If we don't achieve 90% compliance,the County may be put on probation from the CRS
program.
Chairman Johnson noted that Mr. Mason does an excellent job with his due diligence and thanked
him for his work.
Mr. Chrzanowski noted that insurance policies keep going up.
Vice Chairman Lang told the FMPC:
• The county's policies will continue to increase. It was already going up during the NFIP
Legacy Program.
• Since 2014,there's been a monetary cap.Congress instituted an increase cap of 18%.
• They instituted policy changes for the new method. The national Risk Rating 2.0 has
completely flipped ratings upside down. They're now looking at distances from water
sources,the ocean and replacement costs.
• They don't need an Elevation Certificate anymore for ratings. They're using catastrophe
modeling(CAT)monitoring and other factors.
• If you have a current flood-insurance policy,you can go to your insurer and say,"I know
you're rating me off the policy I've had. Can you give me a rating through the 2.0 quote?"
• They don't show us the initial calculations.
• You used to be able to calculate it in Excel and we could show cost savings,but we can't do
that now.
• Louisiana just sued the federal government, saying it's not being transparent with a program
it runs using taxpayer money.
• Flood insurance will continue to increase.
Mr.Mason said when you see flooding,a lot of people don't have flood insurance,but get aid. Do
they have to pay it back?
3
May 2, 2023
Vice Chairman Lang said if the community receives an Individual Assistance(IA)declaration,you
will see that money pumped back into the community. They're not going to get much money.
Generally, for the IHP,the Individual Household Program, it acts like a homeowner's policy.
Mr. Chrzanowski asked also if it has to be paid back.
Vice Chairman Lang said no, but you must carry flood insurance for the life of the structure. He
cited a homeowner's flood-insurance perpetuity clause that follows the life of the structure. Her
policy is going to be$6,000-$8.000 yearly. Currently,she has an NFIP Group Flood Insurance Policy
(GFIP). A GFIP is a three-year,reduced premium policy that is minimum coverage,and is provided
to disaster survivors to give them time to prepare for an actuarial-rated policy after the three-year
policy term is over. If there's another flood and you don't have flood insurance, you won't get aid
from FEMA.
Mr.Vasey asked what the CRS rating is based on.
Mr. Mason said Collier County participates in 17 activities and 57 elements.
6. Collier County FDEP Vulnerability Assessment Grant
Mr. Mason told the FMPC:
• In 2022,the county decided to work with the Florida Department of Environmental
Protection(FDEP)to obtain a grant for a vulnerability study to look at all natural and
manmade hazards.
• The study will tell you what threats we may face from natural disasters.
• It will qualify us for further grant money to try to make the community more resilient to
disasters, including wildfires.
• It will illustrate what challenges the county faces and open us up to future funding.
• We hired the Wood consulting firm, now WSP,to conduct the vulnerability assessment.
They're gathering background data; the final Vulnerability Assessment report. maps and
tables; and peril of flood compliance.
• Florida statutes require peril language.
• This will be integrated with our topography data. It's relevant to the next topic.
• Flood data could come from the National Oceanic and Atmospheric Administration(NOAA)
and Adaptation of Coastal Urban and Natural Ecosystems(ACUNE).
Mr.Vasey asked if the consultant is from Atlanta.
Mr.Mason said they're from Durham,N.C.,the Triangle area.
Mr. Vasey asked how resiliency plays into it.
Vice Chairman Lang said these layers are the starting point of incorporating public infrastructure.
It's an evaluation to get a baseline of what you expect.
Mr.Vasey said we're looking at a venn diagram.
Vice Chairman Lang asked if he's asking if it exists.
Mr.Vasey said he was.
Vice Chairman Lang said no.
Mr. Mason said we're hoping to have it done in nine to 10 months. It's due in 2025. We will be
incorporating the Vulnerability Assessment into the Floodplain Management Plan.
Vice Chairman Lang said they build on each other.
Mr.Vasey asked how the county was building data,telemetry?
May 2, 2023
Mr.Mason told the FMPC
• We have a lot of data in house and we're working with a consultant that uses models. WSP
has an ACUNE-like model.
• The second part is exposure analysis,which identifies the depth of water caused by sea-level
rise, storm surge,and/or a flood scenario. Water surface depths/flood scenarios used to
evaluate assets will include tidal flooding, current and future storm surge flooding, rainfall-
induced flooding and compound flooding.
• When we talk about compound flooding,we're talking about a mixture of sensitivity analysis
that will include an evaluation on impact and risk level.
• Then the study will identify a focus area based on the results of public-outreach meetings and
the steering committee. We may assign focus areas to locations or assets that are vulnerable
and require the development of adaptation strategies.
• The plan is to use the FMPC for outreach and have a subset of it as a steering committee for
the Vulnerability Assessment. We'll be doing that soon.
Mr.Vasey asked when they'll get the Naples Area Board of Realtors(NABOR) involved.
Mr.Mason said anytime. That's a stakeholder we work with.
Mr.Vasey asked how this affects the mitigation strategy.
Vice Chairman Lang said there's a pot of money. They will help identify projects to put on the
priority list. We'll get people from the Local Mitigation Strategy(Working Group)who want to
come.
Mr.Mason said we will present it to the LMS(Working Group).
Mr.Vasey asked if it would be presented to the Planning Commission.
Mr.Mason said the Planning Commission and the Board of County Commissioners,and maybe the
Coastal Advisory Council.
Mr.Vasey said they should include the Southwest Florida Water Management District.
Chairman Johnson asked if everyone would be in the area if they had a meeting on August 8.
(Everyone indicated they would be.)
Mr.Mason said they'd meet then but it depends on how quickly the process moves with the State.
Mr.Vasey asked if they put it out to bid already.
Mr.Mason said the state has given us the green light.
Mr.Vasey asked if they'd have a Notice to Proceed next month.
Chairman Johnson thanked everyone for being flexible about the meeting date.
Mr.Mason told the FMPC:
• The FDEP Vulnerability Assessment is based on resiliency and the final piece will have input
from the steering committee and from outreach.
• The final Vulnerability Analysis must include all results from the exposure and sensiti\ity
analyses and a summary of identified risks and assigned focus areas.
• It should contain a comprehensive list of critical and regionally significant assets impacted by
flooding and sea-level rise, specifying flood scenarios for each impacted asset.
• It will outline critical factors for vulnerability.
7. ACUNE Presentation [Chris Mason]
Mr.Mason detailed a PowerPoint presentation:
5
May 2, 2023
• ACUNE is a modeling Adaptation of Coastal, Urban and Natural Ecosystems and is an
ArcGIS program.
• The project was designed to illustrate the extent of coastal sea-level rise and future storm
impacts and to help communities build resiliency by planning for sea-level rise and climate
change.
• It's been in development with the faculty at UF,University of Miami,USGS (U.S.
Geological Survey)and FGCU.
• It started in 2017 with a three-year NOAA grant that created a program for this region of
Florida,the largest area of tidally influenced public lands along the Gulf of Mexico. It's one
of the state's fastest-growing urban areas.
• There's an online story map of ACUNE: bit.ly/ACUNECollierCounty
• There are various logins for different project staff.
• The ACUNE Geo Tool includes probabilistic flood maps, infrastructure maps,and potential
residential structural loss for current and future scenarios(2030,2060,2100). The scenario
for 2030 is 60,000.
• Sea-level rise and future storms are predicted, as well as wetlands distribution maps, in a
changing climate.
• The ACUNE flood maps show the flood hazard in the region could double by 2060.
• The map shows 1%annual exceedance of 1.7%
• This project is conceptual and uses many different sciences.
• There may be issues with further out-modeling that might not be accurate from 2030-2060.
• The 1%AEP flood has a 1-in-I 00 chance of being equaled or exceeded in any one year and
an average recurrence interval of 100 years; it's referred to as the-100-year flood."
• The"500-year flood"corresponds to an AEP of 0.2%,which means a flood of that size or
greater has a 0.2-percent chance(1-in-500 chance)of occurring in a given year.
[Mr. Mason played a six-minute instructional video about the ACUNE program. Scroll down for the
video here: bit.ly/ACUNECollierCounty]
Mr.Chrzanowski asked Mr. Mason if he could email it to him.
Mr. Mason said that was just a brief presentation about the tool. We're open to discussion with them
about interacting.At this time,the county isn't using this program.
Mr. Chrzanowski asked if he could use it at home.
Mr. Mason said he'd have to contact Dr. Peter Sheng or another staff member. It's not out there for
public use.
Mr.Vasey said he believed it was designed for permit approvals,to show a particular location before
Planning Commission or Board of County Commissioners approval. You do this ahead of time. This
happens to be a NOAA tool and you can use the NOAA website to pull up the same thing.
Vice Chairman Lang said this is specific to the peril of flooding. That was the intent.
Mr.Vasey said we're running out of space in the county. Why don't we use this tool to stop the
nonsense?This is madness. We're not done having high surge. You can't keep permitting things once
they're destroyed.
Vice Chairman Lang said there's a list of variables. They are not just building willy-nilly. ACUNE
was included and we support including this in our vulnerability assets. There was never a time we
were told it would be used for daily permitting.
Mr.Vasey asked what they are using.
6
May 2, 2023
Vice Chairman Lang said we use current regulations,authorized by statute,to include, but are not
limited to,the Collier County Land Development Code, Collier County Law of Ordinances,and the
Florida Building Code(FBC).
Mr.Vasey said the Planning Commission has never been given a copy of the LiDAR.
Vice Chairman Lang said LiDAR has been used.
Mr.Vasey asked him to go to a Planning Commission meeting and ask for a copy of LiDAR.
Mr. Chrzanowski said you can raise all the houses you want,but when the roads start flooding ...
Vice Chairman Lang said we're in agreement. The starting point is you must have a Vulnerability
Assessment.
Ms.Patterson agreed with Mr. Lang. Absolutely, everything starts with a Vulnerability Assessment.
There's going to be a balancing act. Fort Myers Beach will be flooded well before we are. We have a
lot of people with the means to build back. Can they build back smarter?Absolutely. This is a work in
program. Hurricane Ian has put an exclamation point on all these vulnerabilities. ACUNE is a tool
we've supported for five years. We need to take that into consideration and not tie our hands. They're
going to continue to develop.
Mr.Chrzanowski asked when the next storm comes and surge comes to us,would you let me sit at
Vanderbilt Beach and film the surge coming in? I'd rather be in a parking lot.
Ms.Patterson said she didn't know the answer to that question. She could check,but she's sure there
are places he could film.
Mr. Chrzanowski said he'd be willing to sign anything. What does he have to lose? He's 75.
Mr.Vasey suggested the county issue a warning telling residents not to leave garbage cans outside
when a hurricane is coming.
Ms.Patterson said she agrees. They learn something new each time. Things that seem intuitive, such
as don't play in stormwater and don't leave out trash cans, need to be emphasized.
Mr. Mason told the FMPC about ACUNE+, an extension of ACUNE funded by NOAA to address
research gaps identified by the ACUNE project that include.
• Precipitation-induced inland flooding.
• Landward migration of mangrove due to climate change.
• Impact of stormwater system on coastal-urban flooding.
• Economic analyses of surge and wave-induced damage to properties.
• Rapid forecasting of high-resolution storm surge and flooding during user-specified storms.
• An assessment of NNBF for flood protection using the vegetation-resolving surge-wave
model
Mr.Vasey asked if they ever followed up with the MIT guy who was trying to sell a landscape
model.
Ms.Patterson said he's referring to Mr.Ardalan from Harvard. We haven't heard from him in a long
time.
Mr.Vasey asked when the program ends.
Mr. Mason said it sunsets in two years. We want to move as quickly as possible. The program
sunsets in March 2025. He'd like it done within eight to 10 months referring the FDEP sponsored
vulnerability assessment.
8. Mitigation Actions Update
Mr. Mason detailed the status of the actions:
7
May 2, 2023
• Coordinate with local real estate boards to hold all educational meetings about flood
insurance. We will do outreach with NABOR in early June and the City of Naples and City of
Marco Island staff during the rest of the year,reaching out to real-estate organizations, HOAs
and other civic organizations. We'll cover flood insurance,building codes, hurricane
preparation and more.
• Maintain active participation and communication with federal/state/local organizations and
agencies to identify flood-hazard information and enhance flood hazard awareness. including
building construction requirements.FEMA's contractor,AECOM, notified us on March 28,
2022,to say further data is required as part of the appeal process being utilized for select
municipality and private-development lands. FEMA's Letter of Final Determination list has
been scheduled through October 5, 2023. The Collier County Coastal Preliminary Study isn't
contained in any of the proposed letters. It's expected that the final product will possibly be
offered in late 2023. A total of 83 rate-map panels will be revised. One of the holdups is that
Marco Island appealed. They didn't agree with the base-level maps and used a consultant to
refute it and FEMA didn't accept it. Marco Island was trying to enlist a panel,but later
decided against it and will let FEMA release the final product. It's been three years.
Mr.Vasey remembered that three years ago every time you submitted an appeal it went to the back
of the stack.
Mr. Chrzanowski said FEMA said any appeal goes to the end of the line.
Mr. Mason said very few appeals had been submitted and the vast majority were not accepted.
Mr.Vasey asked if there's a change in the Coastal High Hazard Area(CHHA).
Mr.Mason stated the CHHA is a locally adopted planning product separate from the map revision.
Mr. Mason continued his PowerPoint presentation:
• Coordinate with other county departments to develop a program to address all technical-
assistance questions from the general public, including flood-protection assistance, elevation
certificates and building construction requirements. Floodplain Management staff have had
numerous opportunities post-Hurricane Ian to provide these specific services. We do it on a
daily basis and probably have received about 400 phone calls asking how to repair various
things. We've been very busy with phone calls and reviewing data. Last August,Floodplain
Management staff submitted a 200-page report detailing all RLPs that were mitigated over
the past three years. After review,FEMA acknowledged that eight RLPs have been mitigated.
Unfortunately, after Hurricane Ian,we gained some more. Some were removed through demo
and reconstruction,and others were able to improve some with capital projects. It's a constant
battle.
Mr.Vasey asked how many there were in 2022-23.
Mr. Mason said they had 48 and now there are 129 Repetitive-Loss Properties. That means there
were two flood claims in a 10-year period that exceeded $1,000.
Mr. Mason continued his PowerPoint presentation:
• Develop a comprehensive program to provide flood insurance information to property owners
in the SFHA(Special Flood Hazard Area).The program is posted on our website. The county
sent out its annual Flood Protection Newsletter in March.Mailers were sent to Repetitive-
Loss Area properties and Repetitive-Loss Properties, providing information on the status of
the properties and potential retrofitting methods to potentially mitigate those structures.
Mr.Vasey asked to clarify if all of Collier County is in a specific flood hazard area.
Mr. Mason said if we removed the water,97%of the county would be in a flood area.
8
May 2. 2023
Vice Chairman Lang said that without vetting the data,the number of Repetitive-Flood Loss
Properties totals 129.
Mr.Mason noted that you have to double check everything with FEMA. When they created the
report, he found properties that shouldn't be classified as Repetitive-Loss Properties.
9. Other Items/Committee Correspondence
Mr.Vasey thanked Mr. Mason for the ACUNE presentation,calling it an important tool, but he
recognizes that it's not the only tool. He'd still like to see LiDAR data accompany every permit.
Vice Chairman Lang agreed and asked if that's incorporated into ACUNE. They didn't have 2018
LiDAR in some portions of the ACUNE product.
Mr. Chrzanowski noted that other than new construction, LiDAR doesn't change.
Vice Chairman Lang said that the 2018 data is accurate.
Mr. Chrzanowski said you can't get more accurate than a couple of inches. We sent people out to
areas that were shot with LiDAR and everyone was within two inches.Your LiDAR isn't changing,
unless there are glaciers.New development doesn't change LiDAR. They stopped it for some reason.
10. Adjourn—Future Meeting Dates
9 a.m. August 8
10 a.m.November 7
Chairman Johnson said Chris wants to have one of the meetings be a public outreach meeting at a
different location.
Mr.Mason said he'd have to gauge which location would be best.
Chairman Johnson said we'll work with you to establish a quorum.
Mr. Vasey moved to adjourn the meeting. Second by Vice Chairman Lang. The motion passed
unanimously 6-0.
There being no further business for the good of the County, the meeting was adjourned by order of
the chair at 10:28 a.m.

CRS Verification Cycle 2022:Final Report
FDEP Vulnerability Assessment:Collier CountyOn February 13, 2023 Collier County was awarded a grant from the Florida Department of Environmental Protection to conduct a community-wide Vulnerability Assessment.The Vulnerability Assessment (VA) standards in s. 380.093(3), F.S., have been in effect since July 1, 2021, with minor updates effective July 1, 2022. The VA standards, in brief, require that an assessment encompass the entire county or municipality and all critical assets owned or maintained by the grant applicant. Additionally, the standards prescribe scenarios and standards that must be used in the VA, which includes two local sea level rise scenarios from the National Oceanic and Atmospheric Administration’s 2017 intermediate-low and intermediate-high sea level rise projections, and two planning horizons for the years 2040 and 2070, among other technical requirements that would evaluate flood depths for a given scenario.
FDEP Vulnerability Assessment:Collier CountyComponents of Vulnerability Assessment
FDEP Vulnerability Assessment:Collier CountyComponents of Vulnerability Assessment•Acquire Background Data•Critical/regionally significant assets•Topographic data•Flood scenario-related data•Exposure Analysis•Identify the depth of water caused by sea level rise, storm surge, and/or flood scenario. The water surface depths (i.e. flood scenarios) used to evaluate assets shall include the following data: tidal flooding, current and future storm surge flooding, rainfall induced flooding, and compound flooding.
FDEP Vulnerability Assessment:Collier CountyComponents of Vulnerability Assessment•Sensitivity Analysis•Measure the impact of flooding on assets and to apply the data from the exposure analysis to the inventory of critical assets created in the Exposure Analysis Task. The sensitivity analysis should include an evaluation of the impact of flood severity on each asset type and at each flood scenario and assign risk level based on percentages of land area inundated and number of critical assets affected.•Identify Focus Areas•Identify focus areas based on the results of the public outreach meeting and input from the steering committee. Collier County may assign focus areas to locations or assets that are particularly vulnerable and require the development of adaptation strategies.
FDEP Vulnerability Assessment:Collier CountyComponents of Vulnerability Assessment•Final Vulnerability Assessment Report•Finalize the Vulnerability Assessment (VA) report pursuant to the requirements in s. 380.093, F.S. and based upon the steering committee and public outreach efforts. The final VA must include all results from the exposure and sensitivity analyses, as well as a summary of identified risks and assigned focus areas. It should contain a list of critical and regionally significant assets that are impacted by flooding and sea-level rise, specifying for each asset the flood scenario(s) impacting the asset.
NOAA ACUNE Project:Collier CountyAdaption of Coastal Urban and Natural EcosystemsACUNE & ACUNE Plus
NOAA ACUNE Project:Collier County"Adaptation of Coastal Urban and Natural Ecosystems (ACUNE)", was funded with almost one million dollars over a 3-year period due to its scientific merits as well as strong stakeholder commitment. Its major goal is to inform the Collier County urban and natural system managers of the current and future flood hazard and vulnerability of infrastructures (buildings, roads, bridges, stormwater systems, cultural sites, beaches, archeological sites, and wetlands, etc.). The value of coastal wetlands in reducing flood damage to residential structures is also being assessed.The ACUNE Geo Tool includes probabilistic flood maps, infrastructure maps, and potential residential structural loss for current and future scenarios (2030, 2060, 2100). These scenarios include the probabilistic sea level rise values predicted by NOAA (2017) and future storms predicted by CMIP5 climate models, and wetland distribution maps in a changing climate. Importantly, the ACUNE flood maps are simulated by a three-dimensional vegetation-resolving surge and wave modeling system CH3D-SWAN with time varying wetland distribution maps by USGS. The ACUNE flood maps show that the flood hazard in the region could double by 2060.
NOAA ACUNE Project:Collier CountyAEP: Annual Exceedance Probability
NOAA ACUNE Project:Collier County•11%% andd 0.2%% AEPP - In the 1960's, the United States decided to use the 1-percent annual exceedance probability (AEP) flood as the basis for the National Flood Insurance Program. The 1-percent AEP flood has a 1 in 100 chance of being equaled or exceeded in any 1 year, and it has an average recurrence interval of 100 years, it often is referred to as the "100-year flood". The "500-year flood" corresponds to an AEP of 0.2-percent, which means a flood of that size or greater has a 0.2-percent chance (or 1 in 500 chance) of occurring in a given year.
