Obviously, as  geologists they  care about the  rocks, but  it is

Often  times, they  perform  these LiDAR  surveys  when there  is

REPRESENTATIVE  PARISH said  one of  his Juneau  constituents was

MR. PAPP  answered that in  2018 made two  publications regarding

CO-CHAIR  TARR   asked  how  their  work   is  affecting  housing

MR.  PAPP replied  that  they coordinate  efforts  with FEMA  and                                                               
other federal  agencies so that efforts  aren't duplicated. Also,

part of what they do is  work very closely with community leaders                                                               
to help them understand the information they produce.                                                                           
CO-CHAIR TARR asked if they  interact with insurance underwriters                                                               
and  who  advocates   on  behalf  of  the   homeowners  in  those

MR.  PAPP  replied  that DGGS  doesn't  interact  with  insurance

DGGS basically  just provides scientific information  that can be

SENATOR STEDMAN said for FEMA you opt  in, and the hook is if you

kind of  game they  are playing.  Premiums are  high as  a couple

REPRESENTATIVE  PARISH asked  what manner  of formal  action from                                                               
the legislature would be most helpful in resolving this.                                                                        
MR. PAPP said he would get back to them on that.

focus is on  coastal flooding and erosion.  Alaska's coastline is

equator.  It makes  up about  40  percent of  the U.S.  coastline

The  coastline has  permafrost (ground  with  a temperature  that

Alaska's coastal infrastructure and  the coastline are subject to                                                               
steep  increasing  temperatures.  Alaska's northern  and  western                                                               
coastlines have  sea ice forming  along it in the  winter months.                                                               
In recent years during the  regular fall and winter storm seasons                                                               
the extent  and thickness of it  has been at record  lows. Storms

transfer that  energy to the  coastal communities if the  sea ice

MS. OVERBECK  said that  Alaska has to  account for  relative sea

determine what those  rates are. In northern  and western Alaska,                                                               
few  studies are  available showing  relative sea  level rise  in                                                               
comparison to that.                                                                                                             
CHAIR GIESSEL asked  her to comment on a common  question that as                                                               
the sea ice melts the sea level will rise.                                                                                      
MS. OVERBECK  answered that relative  sea levels are  expected to

back to her on.                                                                                                                 
CHAIR GIESSEL observed  that if sea ice melting  raised the level

flow  as the  ice melted,  but that  is not  what happens.  Water                                                               
while  it  is frozen  will  displace  the  same amount  of  water                                                               
consistently. She  could see how  land-based glacier  ice melting                                                               
could contribute, to a minor degree,  to the ocean level, but sea                                                               
ice melting does not raise the  level of the ocean, as a physical                                                               
MS. OVERBECK said she will get back to her.

CO-CHAIR  JOSEPHSON   said  he   wanted  Ms.  Overbeck   to  feel                                                               
comfortable in responding to Senator  Giessel's question. He said                                                               
legislators look at  myriad legislation and try to  be experts in                                                               
every field, whereas Ms. Overbeck  spends her time on this issue.                                                               
He asked  if she agrees  based on  her reading and  research with                                                               
the Senator's statement.                                                                                                        
MS.  OVERBECK said  she was  not prepared  to answer  the chair's                                                               
comment, at  this time, from  the perspective of her  office that                                                               
considers   any  published   research  and   takes  on-the-ground

level rise  in a particular region  off the top of  her head, but                                                               
she would really like to get back to them on it.                                                                                
CO-CHAIR JOSEPHSON  responded that  before the comment  was made,                                                               
Ms. Overbeck said  that, in fact, relative sea  level rise (RSLR)                                                               
was attributable in part to mankind.                                                                                            
MS.  OVERBECK  responded  that  it   was  not  her  intention  to                                                               
attribute sea level  changes to anything at this  time but wanted                                                               
to speak to the observations that are made on the ground.

REPRESENTATIVE DRUMMOND  said there  looks to be  significant sea                                                               
level fall  in Kodiak, Cook  Inlet, just north of  Prince William                                                               
Sound near the Yakutat area (referring to slide 8).                                                                             
MS. OVERBECK said that is correct.                                                                                              
REPRESENTATIVE DRUMMOND  asked if she  had some idea why  that is                                                               
happening in those particular places.                                                                                           
MS. OVERBECK replied  that is occurring in  those regions because                                                               
of  the  relative  motion  of  the  land  there,  which  is  very

than global sea levels change.                                                                                                  
CO-CHAIR  TARR commented  that arrows  are  sized differently  to

MS. OVERBECK  agreed and summarized  that the map  shows measured

arrows show the relative sea  level decline. The magnitude of the                                                               
arrows is also associated with that.

SENATOR STEDMAN said the University  of Alaska did an analysis on                                                               
sea level movement in Southeast  and attributed it to the melting                                                               
of the ice, especially around  Mount Fairweather and the glaciers                                                               
where land is rebounding. The Forest  Service has also done a lot

CHAIR GIESSEL said  that Norway has multiple  evidence of village

CO-CHAIR TARR asked Ms. Overbeck  if her office is collecting all                                                               
of the data  for their modeling or is it  coordinating with other                                                               
MS. OVERBECK replied her office  doesn't collect any data that is

CO-CHAIR TARR asked her to differentiate the coastal types.                                                                     
MS. OVERBECK answered there are  three different types of coastal

sewage lagoon  that is  also near  an eroding  coastline. Coastal                                                               
storms have  been documented to  erode as much 10-20  feet during

Many dump sites  in western Alaska are also  located near coastal                                                               
rivers and  coastlines. The community  of Kotlik  dumps materials                                                               
that were  actually floating in the  river at a high  tide during                                                               
their site visit.  The community that operates this  dump site is                                                               
able to  get heavy equipment  into it  when the river  is frozen.                                                               
However, if  the river  doesn't freeze, they  can't do  that. So,                                                               
they end up  having issues with dump materials  flooding into the                                                               
MS. OVERBECK  said the  Nunapitchuk primary  dump site  is fenced

Other pictures from 2013 showed the  Gambell dump site that had a

those events are anticipated in  fall and winter, but it happened

CO-CHAIR TARR  provided a time  check and asked how  using drones                                                               
improves the ability to get data.                                                                                               
MS.  OVERBECK   answered  that  using   drones  allows   them  to                                                               
continuously collect an  entire area of elevation  data. They are                                                               
also able to get an image of  that area, as compared to going out                                                               
with one survey rod and  collecting those data sets individually.                                                               
Local  individuals are  interested  in using  drones  as part  of                                                               
potential  community-based monitoring  programs that  collect the

CO-CHAIR  TARR commented  that the  legislature is  interested in                                                               
maximizing the use  of those technologies, because  they know the                                                               
data  is needed,  but the  cost of  sending people  out to  these                                                               
remote locations is prohibitive and sometimes even prevents it.                                                                 
MS.  OVERBECK said  DGGS collects  data by  using remote  sensing                                                               
methods and  either contracts it  out or collects  it themselves.                                                               
Any drone survey  requires some level of ground  control in order                                                               
to  have  an  accurate  product, but  ground  control  can  cover

MS.  OVERBECK said  DGGS houses  all the  elevation data  that is                                                               
available  in  the  state  in  one  location  regardless  of  who                                                               
collects it  and provides it to  the public in a  format they can

She  said   DGGS  helps  with   both  disaster   preparation  and

forecasts for  that region and  then provides a forecast  for the                                                               
communities. They are  moving from a method  of regional forecast                                                               
to  more  localized  forecasts,   which  provides  more  detailed                                                               
information to individual communities.  DGGS assists with that by                                                               
using  their  color index  map,  which  is  a conversion  of  the

specifically  that   flooding  is   expected  on   Front  Street.                                                               
Seventeen communities  in western  Alaska have these  maps, which                                                               
are created wherever  they have baseline data in order  to do it.                                                               
She offered to provide that information to interested parties.                                                                  
She said  that disaster declarations  have been rejected  by FEMA                                                               
because there was no proof  that the event actually happened. So,                                                               
they want  to be able to  give those communities the  capacity to                                                               
document those  disastrous events by providing  survey benchmarks                                                               
on  elevation  models that  give  an  idea  of  what parts  of  a

MS.  OVERBECK  said her  department  just  completed a  community

as many local  Hazard Mitigation Plans look to the  State Plan in

they had  data that  could actually  be processed  in conjunction

compiled  into a  map showing  erosion rates  around communities.                                                               
The community of  Newtok, for instance, erodes 63  feet per year.                                                               
This  data allows  them  to project  shorelines  into the  future                                                               
based on  their historical rates  of erosion  to give an  idea of                                                               
what parts of the coastline are more vulnerable.

CO-CHAIR TARR  asked if  DGGS is planning  to create  a community

there  are gaps.  So, eventually  that number  of 17  communities

MS. OVERBECK  answered that  they want to  create these  maps for

responsibility  for  community  planning gets  transferred  as  a

MS. OVERBECK replied  that some state partners  like the Division

She said  many engineering  firms operate  in western  Alaska and

MS.  OVERBECK  concluded  that the  Coastal  Hazards  Program  is

Also,  the Alaska  Geo-spacial Council  has a  coastal strategist

MS. OVERBECK  said she  couldn't list  all of  the collaborators,                                                               
but  most of  their  technical assistance  comes  from NOAA,  the

She displayed the final slide of contact information.

CO-CHAIR  JOSEPHSON  asked  if   the  Governor's  Climate  Action                                                               
leadership team had consulted her office.                                                                                       
MS. OVERBECK answered yes, and  she presented to their group this                                                               
last year. A number of  the members are active collaborators with                                                               
the DGGS.                                                                                                                       
CO-CHAIR  JOSEPHSON   observed  that  Unalaska  must   have  been                                                               
situated roughly where  it is, because we know  about the Russian

understood  that villages  used to  move more  but stopped  doing                                                               
that partly  because the  U.S. encouraged them  to be  more fixed                                                               
and sedentary.  Ms. Overbeck mentioned  Port Heiden's  issue back                                                               
in the 1980s,  and he wanted to know if  her historical knowledge                                                               
allowed  her to  say with  confidence that  erosion is  worse now                                                               
than  historical knowledge  suggests  it was  even with  villages                                                               
being more transient then and  that this wasn't happening to this

MS. OVERBECK replied that their data  goes back only to the 1950s                                                               
and that data would be different  for each location and require a                                                               
detailed analysis.

REPRESENTATIVE BIRCH thanked  her for a great  briefing and asked                                                               
who owns all the data and where it resides.                                                                                     
MS. OVERBECK  replied the  data collected by  the state  is owned                                                               
and housed by the state.                                                                                                        
MR.  PAPP added  that the  data they  use in  their analysis  are                                                               
publicly available for  anyone for no cost.  The department wants                                                               
to promote that knowledge.

SENATOR  MEYER asked  if he  had  analyzed what  would happen  to                                                               
coastal erosion with the sewage  lagoons and dump sites if Ballot                                                               
1 passes.                                                                                                                       
MS.  OVERBECK replied  she was  not familiar  with what  Ballot 1                                                               
would do, but she would get back to him on that.                                                                                
REPRESENTATIVE LINCOLN  asked if  they are doing  any projections                                                               
in terms of future inundation if sea levels rise.                                                                               
MS. OVERBECK  answered that  they are  not making  projections on                                                               
sea level  changes with  surge level modeling  at this  time. The                                                               
data has to be collected first  and the next step would be making                                                               
models and projections.                                                                                                         
REPRESENTATIVE  LINCOLN  asked  if  that  next  step  is  in  the                                                               
abstract or  if it  is the  actual next step  she is  planning to                                                               
MS.  OVERBECK  said  that  would  be a  long-term  plan  for  the                                                               
program, which doesn't have the capacity to do it at this time.                                                                 
MR. PAPP  added that they  work with a  lot of other  partners to                                                               
make this information  possible and as their data  goes back only                                                               
so  far, useful  projections  need additional  data collected  in

communities themselves.                                                                                                         
REPRESENTATIVE LINCOLN  asked if  they need direction  or funding                                                               
from the legislature and if they have a timeline.                                                                               
MR. PAPP replied they don't have a timeline at this point.                                                                      
REPRESENATATIVE LINCOLN thanked  them both for the  work they are                                                               
doing saying it is a major  issue for the state and his district,                                                               
especially.   Some   iconic   Alaskan   communities   are   under                                                               
existential threats from sea level  change and storms, and having                                                               
that information  is a huge first  step in addressing it.  But at                                                               
some  point, soon  they will  need  to apply  some resources  and
