FEMA CTP Floodplain Mapping Studies/Digital Flood Insurance Rate Maps Release

What is it?

  • The Flood Control and Water Conservation District is collaborating with FEMA through the Cooperating Technical Partners (CTP) Program in order to maintain up-to-date floodplain mapping and other flood hazard information within Placer County. The main objective of the program is to provide new or improved 1% annual chance floodplain, or 100-year, mapping of major creeks within developing areas of the County.
  • Through three CTP efforts, over 120 miles of new or updated mapping will be provided in urbanized areas of the County.
  • The creeks to be studied were prioritized through the District Technical Advisory Committee (TAC) consisting of member agency staff that identified the need for new or updated areas of floodplain mapping.
  • The District often leads the initial hydrologic studies which serve as the basis for the updated or new mapping produced separately by FEMA’s mapping contractors.
  • District staff have been providing regular updates regarding the CTP process to the District Board and cooperating member agencies at public Board of Director meetings.
  • Placer County is the first jurisdiction to receive the new FEMA Digital Flood Insurance Rate Map (DFIRM) format which replaces the current paper map format. The DFIRMs are being released simultaneous to the CTP mapping studies depicting the new or updated 1% annual chance floodplain.

 Where is it?

  • Attend a Public Outreach Meeting on August 7, 2018 from 5:30 - 7:30 for more information. Meeting will be held in meeting rooms 1 and 2 at the Maidu Community Center located at 1550 Maidu Drive in Roseville.
