 Description 
March 15, 2018 Staff is responding to inquires from residents over the contents of the FEMA letter.
 February 26, 2018  Copies of the FEMA 90-Day Appeal Period letter were sent to residents.
 February 19, 2018 Received correspondence from FEMA stating that the 90-day appeal period for new preliminary Flood Insurance Rate Maps (FIRMs) will begin on February 28, 2018.
 August 25, 2017 Staff met with our floodplain consultant to discuss possible comments. One comment will be submitted related to the new draft Flood Insurance Rate Maps (FIRMs).
 July 28, 2017 Village staff attended the FEMA briefing on 07/27/2017 in preparation for the upcoming open house.
July 14, 2017 Staff send out letters to residents that will be impacted by the proposed map changes.
 July 7, 2017 Staff will be sending out letters to residents that will be impacted by the proposed map changes notifying them of the upcoming open house on 07/27/2017.
 June 30, 2017 Staff and V3 consultants met to discuss the changes to the draft Flood Insurance Rate Map (FITM) since last published in 2015. It appears that there will be a net decrease in number of properties in the floodplain from the previous draft FIRM and overall a decrease from the current FIRM.
 June 23, 2017 The open house has been confirmed for 07/27/2017 from 4:00 p.m. to 8:00 p.m. at the DuPage County auditorium. Prior to that there will be a separate briefing from municipal officials and staff. Staff will be sending out notices of the open house to residents that would be impacted by the proposed map changes.
 June 9, 2017 Staff received and is reviewing new draft Flood Insurance Rate Maps (FIRMs) and FEMA's disposition of comments from the previous versions of the draft maps. County staff has indicated they will be placing the new maps on the County website. FEMA will be conducting community meetings in July.
 April 14, 2017 A 06/01/2017 release date for the new floodplain maps have been announced. The open house is scheduled for 07/27/2017.
 March 10, 2017 Staff attended the DuPage Stormwater Committee meeting on 03/07/2017. DuPage County staff indicated no change in status on the floodplain maps for Sugar Creek. They are still waiting for the Illinois State Water Survey (ISWS) to take action on the last re-submittal. It is our understanding that revised maps are not available for viewing by Village staff until authorized by ISWS.
 January 27, 2017 Staff has contacted the Illinois State Water Survey to verify that there will be another public comment period after revised floodplain maps are released to the public.
 August 12, 2016 At a recent DuPage County Municipal Engineers meeting County staff provided an update. FEMA is reviewing revised maps. FEMA will decide whether the approval process will re-start from the beginning or continue from where it left off. The new maps would not be finalized until 2017 at the earliest.
 April 29, 2016 County staff displayed proposed new floodplain maps which would decrease the number of properties to be mapped into the floodplain. Village staff will attempt to obtain copies of the draft new maps.
 April 15, 2016 Staff met with two residents in the Sugar Creek watershed this week. We developed a list of questions to present to DuPage County staff at a meeting later this week.
 April 1, 2016 Staff will request an update from DuPage County and schedule a follow-up meeting with two residents in the Sugar Creek watershed.
 March 4, 2016 County staff has reported that they are taking another look at the proposed floodway for Sugar Creek.

  • The Village received the following e-mail from the State Water Survey:

This message is an update from the Illinois State Water Survey (ISWS) on behalf of the Federal Emergency Management Agency (FEMA) regarding the DuPage County, Illinois Flood Insurance Rate Map (FIRM) project.

Comments received on the June 3, 2015 Preliminary products (FIRM, Flood Insurance Study, FIRM Database) have been inventoried. Each community for which comments were submitted should have received a Comment Acknowledgement letter from FEMA.  This letter lists and/or summarizes all comments received from communities, contractors, citizens and other agencies.  FEMA, ISWS and DuPage County Stormwater Management are working toward comment resolutions.

It has been determined that DuPage County Revised Preliminary products will be necessary.  This will result in an additional products release and community review.  A timeline has not been determined.

The 90-day appeal period discussed at the open house on July 29, 2015 has been postponed.  It will be initiated after a Revised Preliminary comment period has been completed.

No action is required on your part at this time.  If you have questions concerning the administrative processes associated with this project, please contact Bill Heyse of FEMA Region V either by telephone at (312) 408-5323 or by e-mail at William.Heyse@fema.dhs.gov.

  • Staff has tabulated the results of the 40 flood certificates that have been requested by Village residents.  Some residents have inquired about Letters of Map Amendment (LOMA) which would remove them from the current 100 year floodplain and potentially eliminate the need to purchase flood insurance.
  • A FEMA representative made a presentation to a group of residents on December 14, 2015.  He discussed the floodplain mapping process as well as flood insurance regulations.  Some of the residents indicated that they disagreed with the proposed floodplain maps.  Others were concerned about the cost of flood insurance. 
  • Residents are requesting that the Village hold a meeting to address questions and concerns regarding flood insurance and how the financial institutions will decide whether it is required.  Staff is attempting to find an appropriate subject matter expert that can provide relevant information.
  • Staff received an e-mail from IDNR indicating that they have received hundreds of comments on the draft preliminary maps.  Apparently there are enough valid comments that the maps are going to be revised.  We were not given any specifics about which map panel would be revised.
  • Staff sent out over 330 letters regarding the cost sharing program for elevation certificates.  We have received over a dozen payments already and have answered numerous inquiries.  Additional information regarding elevation certificates has been posted on the Village’s web site at http://www.invillapark.com/196/Public-Works-Department (scroll down to FEMA flood maps).
  • Staff and Willowbrook High School submitted comments to the Illinois State Water Survey (ISWS).  We met with two consultants and expect to obtain proposals for obtaining elevation certificates for those properties impacted by the flood map changes.  Staff will need direction whether the Village is merely brokering a better rate for the certificates or will actually share in the costs.
  • The Village hosted an open house for Village residents on 8/10/15.  An overview of the timetable for adoptions of the Flood Insurance Rate Maps (FIRMs) by FEMA was provided based on information previously provided to Village staff.  Hard copies of the proposed FIRMs were available for viewing as well as a computer terminal with a ling to the County’s interactive maps of the proposed FIRM.  Village staff was also on hand to answer questions and assist with drafting of comments to be submitted to the Illinois State Water Survey (ISWS).  Comments are due August 28, 2015.  The 90 day appeal period will commence later this year.  Any appeal must be based on better technical data and would like require extensive computer modelling, but simple appeals based on more current topographical data may be more feasible.
  • Village staff and Willowbrook High School will both be submitting comments in response to a proposed mapping of the new school addition into the regulated floodway.  An appeal is also likely.
  • The Du Page Mayors and Managers Conference (DMMC) has also submitted comments that are considered to be applicable to all communities.
  • The Director attended the FIRM open house on July 29, 2015.  This initiated the 30 day comments period.  After a general presentation on the mapping process, insurance ramifications, and the timetable we discussed the proposed remapping of Willowbrook High School.
  • Some properties are proposed to be mapped out of the regulatory floodplain.  This would allow possible reductions or elimination of the need to obtain flood insurance.  Letters were sent to those property owners and they were encouraged to attend the FEMA open house on July 29, 2015 to get further information.
  • Second notification letters with location of the Flood Insurance Rate Map (FIRM) open house (July 29, 105, Du Page County Auditorium) were mailed out last week.
  • Staff met with V3 consultants to discuss the map review and appeal process.
  • Notification letters have been mailed out to residents who are apparently being mapped into the 100 year floodplain for the first time or who’s previous Letter of Map Change (LOMC) will be voided by the proposed new Flood Insurance Rate Maps (FIRMs).
  • FEMA issued preliminary new floodplain maps on June 3, 2015.  FEMA’s site for Preliminary Data:  http://www.fema.gov/view-your-communitys-preliminary-flood-hazard-data-0.  Click on the preliminary flood data search tool, “preliminary flood data search tool”, then complete the drop down menu choices.
