Boulder County and Incorporated Areas Designation
Town of Lyons Designation Request

As of the completion of the Boulder County, Colorado and Incorporated Areas PIS (PIS effective
date June 2, 1995), we have not received the Town of Lyons' designation request letter. This
memorandum serves as a summary of the Town's assumed position on the designation based on
discussions with local officials.

Mr. Gary Cinnamon was contacted by phone in November, 2000, and January and March, 2001.
Mr, Cinnamon indicated that the biggest problem with floodplain mapping is on St.Vrain Creek
as it leaves town. Lyons is coordinating with Boulder County on submitting a LOMR to FEMA
Due to delays, the Town has proceeded with the LOMR independently. CWCB has already
reviewed and approved the LOMR submittal so the Town will be submitting it to FEMA. It was
noted to Mr. Cinnamon that this designation will not take care of this process - the designation
and LOMR are parallel but separate process. Mr. Cinnamon indicated that he would draft the
designation request letter and return it to CWCB, but was not received prior to publication of the
report,
