Flood Protection and FEMA Map


FEMA Flood Maps

On April 17, 2001, the Federal Emergency Management Agency (FEMA) issued a revised 100 year Flood Insurance Rate Map (FIRM) for Woodland and the unincorporated area affected by flows from lower Cache Creek. The new maps are similar in extent to the draft maps issued in October 1998. Those maps were appealed; the revised maps generally show shallower flooding in Woodland. They do show approximately 34 percent of the City in the flood plain, including most of the industrial area. The residential flood depths appear to be generally under 2 feet, with the vast majority under 1 foot in depth. The industrial area generally shows deeper flooding (generally 2-7 feet), however in all cases, the base flood elevations on the FIRMs should be checked against pad elevations.

Comments were submitted on the new (April 2001) maps and we anticipate the maps will be reissued in June or July 2001 for the formal, 90 day Appeal Period. We do not expect any significant change in the maps as a result of the comments submitted.

After the appeal period comments, if any, are resolved, FEMA has advised they will issue a "Letter of Final Determination" which will accompany the set of final maps, and establish an effective date for the maps that will be 6 months from the date of the Letter of Final Determination. The effective date for the maps (for FEMA flood insurance purposes) is estimated to be in the January to April 2002 timeframe.

Based on the FIRM maps, there is clearly a need for 100 year flood protection for the City of Woodland.

What is Sacramento doing about their flood problems?

Flood Protection Project

The City is working closely with FEMA, the Army Corps of Engineers, the California Department of Water Resources, and the County to complete a $2.5 million Feasibility Study in 2002, which will identify the preferred alternative for flood protection for the City of Woodland. Our Congressional Representative, Doug Ose, is working hard to get authorization included in the Water Resources Development Act (WRDA) 2002 legislation for federal funding, which is required if we are to start construction on flood protection improvements in 2003/4. Construction will take at least 3-4 years to complete.

Voter Approval for Funding

The flood protection options being studied range in cost from $40-$100 million, with the state and federal government funding up to 88 percent of the costs. The local cost share is a minimum 12%. We will be exploring funding alternatives, but they will likely involve voter support in one form or another, probably in 2002.
