High Water Mark Information

Know Your Line: Be Flood Aware

The "Know Your Line: Be Flood Aware" High Water Mark initiative, created by FEMA and other federal agencies, helps remind residents of historic major local floods and encourages the community to prepare for future flood risks. Roseville has posted high water mark signs to show how high flood waters have risen in the past.  

Roseville has made a $20 million investment in developing flood mitigation infrastructure improvements and instituting a comprehensive floodplain management program. As a result, Roseville is the only city in the United States to hold a Class I rating as part of FEMA's Community Rating System. This means Roseville property owners save up to 45% on their flood insurance premiums. Learn more Roseville floodplain facts.

Flood control improvements in this area included the removal of the culverts under the railroad tracks on Dry Creek, downstream of Vernon Street, thereby removing over 150 homes from the floodplain.

Dry Creek at Columbia Avenue

January 10, 1995 high water mark elevation: 147.58 feet above sea level

Columbia Avenue, Folsom/Maciel Neighborhood - January 10, 1995

Home Elevation Program. FEMA funded 75% of this $1 million program to elevate flood-prone homes. These are structures that would not be brought completely out of the floodplain by construction of our flood control project. Homeowner participation was voluntary. 27 of 44 homeowners eligible elevated their homes via this program. Most of those 27 are located in the Folsom/Maciel neighborhood along Dry Creek, including homes on Columbia Avenue.

This project brought the entire Tina/Elisa neighborhood of 40 homes out of the floodplain. Cost = $3 million (100% City funded).

Post-Flood Control Project 100-year Storm Water Surface Elevation: 157.10 feet above sea level

Champion Oaks Drive - January 10, 1995

Flood control improvements in two areas on Linda Creek: the Champion Oaks/West Colonial Parkway area, and the Sunrise/Oakridge area. This project reduced the size of the floodplain resulting in 233 homes no longer being located in the floodplain, and reducing the risk of flooding for 44 additional homes. Cost = $16.1 million ($8.7 million FEMA funds, $7.4 million City funds).
