BACKGROUND: During the months of May and June of 2015 the City of Lawton received unusually heavy rainfall. The heavy rainfall events caused extensive damages to several sections of the Ellsworth Spillway. CH2M Hill/Jacobs Engineering was contracted to investigate and design necessary repairs in order to restore the spillway to pre-damage functionality. On September 13th 2016, the City Council approved Amendment No. 5,6,7,8 and 10 with CH2M Hill/Jacobs Engineering for review of standard methods, hydraulic, geotechnical numerical analysis, seismic analysis to determine the maximum credible earthquake motion at the site, perform design of rehabilitation and completion of a Benefit Cost Analysis of the Ellsworth Spillway. Currently the design is at 100% complete and a positive Benefit Cost Analysis has been developed. The estimated current construction cost for repairs to Ellsworth Spillway is ±$20 million dollars. The Design has been permitted by OWRB for construction. On August 8th, City Council accepted funding agreements for the FEMA HHDFY22 Grant in the amount of $925,251.00, the Oklahoma State Competitive ARPA grant in the amount of $1,000,000.00, and the Oklahoma State Designated ARPA Grant in the amount of $10,000,000.00. Remaining funds will come from City match up to $8 million. This project is imperative to continue to provide a Safe Community to our Citizens as Public Utilities and the City of Lawton strive to meet the goals of the True North Culture Statement.
