Item #9 CITY OF COLTON AGENDA REPORT FOR THE CITY COUNCIL MEETING OF MARCH 15, 2005 TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: AMER JAKHER, P.E., CITY ENGINEER SUBJECT: APPROVE RESOLUTION TO ADOPT THE REVISED FLOOD INSURANCE RATE MAPS TO REFLECT LETTER OF MAP REVISIONS (LOMR). DATE: MARCH 7, 2005 BACKGROUND: The 550 -foot -tall Seven Oaks Dam is located on the Santa Ana River in the upper Santa Ana Canyon about eight miles northeast of Redlands. Authorization for the project construction is contained in the Water Resources Development Act of 1986. Construction began in May 1994 and was completed on November 15, 1999. The construction of the Seven Oaks Dam has led the Federal Emergency Management Agency to issue new flood insurance rate maps for areas surrounding the Santa Ana River in San Bernardino County, which means relaxed building restrictions and reduced insurance rates for county residents and employers. The new maps dated February 23, 2005 changes zone A-99 and Zone AE to Zone X. In Zone X, the properties are no longer in the 100 year flood plain. ANALYSIS/DISCUSSION: The request for the revision of the Flood Insurance Rate Map (FIRM) and the Flood Insurance Study (FIS) was requested by the San Bernardino County. The revised maps show a reduced floodplain and temporary restrictions for the old floodplain. The restricted area, Zone AE, shows the reduced floodway around the Santa Ana River because of the completion of the Seven Oaks Dam. The area that is no longer in the flood plain are shown as Zone X. The cities of Colton, Grand Terrace, Rialto, Highland, Redlands, San Bernardino and nearby unincorporated areas have new maps that became effective February 23, 2005.
