Timberline Flood Risk Management
In an effort to reduce the reliance on emergency flood fighting efforts in the Timberline Addition, the City of Fargo, with assistance from Houston Engineering, developed a multi-phase project that constructed earthen levees, concrete floodwalls, and completed storm sewer improvements within the addition.
Following the record flood of 2009 and the repeated threat of flooding to levels in excess of 40-feet in 2010 and 2011, the residents in Timberline indicated to the City that they had a strong desire to develop a project that would protect the addition. As a result and prior to the 2010 flood, the City constructed an emergency levee in four locations within the addition. In the summer of 2010, the City worked closely with the neighborhood and developed a project to convert these emergency levees to permanent structures. This project was Phase 1 of flood risk management for the Timberline Addition. The low bid submitted for Phase 1 was submitted by Master Construction with a total bid price of $1,235,161.60. Construction of this project began in the fall of 2010 and continued during the 2011 construction season. The majority of the work under Phase 1 was completed in 2011.
In the fall of 2010 and continuing into 2011, the City held meetings with the neighborhood to develop Phase 2 of the flood risk management project in the Timberline Addition. In the spring of 2011 there was a threat of flooding in excess of 40-feet, which resulted in the City constructing emergency levees where no levees had been previously constructed. These locations were planned to be Phase 2 of project. In the summer of 2011, additional neighborhood meetings were held to develop a design of Phase 2, which consisted of earthen levees and concrete floodwalls. This project was bid in the summer of 2011 with the low bid being Master Construction with a bid of $1,766,080.05. Construction of this project began in the fall of 2011 and was complete by the middle of the summer in 2012.
The two Timberline projects are connected to the west levee constructed under the Meadow Creek Flood Risk Management project, which results in a continuous line of protection along the western side of Drain 27 & Drain 53 from 40th Ave. S. to 52nd Ave. S.
