REQUESTED COUNCIL ACTION:
Does city council support an amendment to Title 10 of the Littleton Municipal Code to adopt the most recent Federal Emergency Management Agency (FEMA) Flood Insurance Study and Flood Insurance Rate Maps for Arapahoe County, which slightly revise Dutch Creek and Coon Creek floodplain boundaries in the City of Littleton?
BACKGROUND:
The Urban Drainage and Flood Control District (UDFCD) updated the floodplain study for Dutch Creek, Coon Creek, Lilley Gulch, and Three Lakes Tributary in a Flood Hazard Area Delineation Study dated March 2008. The previous floodplain study was dated 1978. The updated study was sent to FEMA as a Physical Map Revision (PMR) to update the Flood Insurance Study and Flood Insurance Rate Map(s). That PMR was recently approved by FEMA and is effective on April 18, 2018. Small portions of Dutch Creek, Coon Creek and Three Lakes Tributary are within the City of Littleton. Most of the floodplains for these drainages are located in Jefferson County, to the west of city limits.
The City of Littleton has been a participating National Flood Insurance Program (NFIP) community since 1978 when the first floodplain maps were created in the city. Participating communities in the NFIP are required to update their floodplain regulations to adopt new mapping, prior to the effective date. Littleton was notified of this requirement by letter on October 18, 2017. The floodplain regulations update will include changing the date of the FEMA Flood Insurance Study referenced in Municipal Code 10-6-3(B) to April 18, 2018.
STAFF ANALYSIS:
In order to remain in good standing within the NFIP, which makes flood insurance available to residents, updating the floodplain regulations to reference the most current FEMA report is required. The floodplain revisions being adopted by FEMA affect a small area of Dutch Creek in South Platte Park, owned by the Colorado Water Conservation Board and a sliver of floodplain along Coon Creek off S. Zenobia Court (the revision appears to remove a house from the floodplain). The portion of Three Lakes Tributary affected by this revision is located in Columbine Valley. All properties adversely affected by the revisions were notified by letter, from UDFCD in the summer of 2016.
FISCAL IMPACTS:
There is no fiscal impact to the city for this update to floodplain regulations. Remaining within the NFIP is a financial benefit to Littleton residents.
STAFF RECOMMENDATION:
Staff recommends approval of the ordinance to update the municipal code.
PROPOSED MOTION:
Proposed Motion
I move to approve the ordinance on second reading amending Title 10, Chapter 6, Section 3(B) of the Littleton Municipal Code in order to reference the most recent Federal Emergency Management Agency Flood Insurance Study and Flood Insurance Rate Map.
