Purpose: Okaloosa County (COUNTY) is working to plan for the development of an additional potable water source to meet the future needs of the County's citizens, businesses and military establishments. In 2006, the North West Florida Water Management District (NWFWMD) completed an alternative evaluation of potential water supply projects for the COUNTY, which identified approaches for increasing water supply capacity in the future. Follow up evaluations and studies were completed, including the Water Supply Needs Analysis-Okaloosa County Technical Memorandum (TM), which was completed in July 2012. This TM presents four potential alternatives including: 1) No Action Alternative, 2) Surface Water Offline Reservoir, 3) Surface Water Direct Withdrawal, and 4) Enhanced Conservation and or Reuse Alternative. The purpose of this project is to ensure that a range of alternatives, to include all reasonable alternatives, is considered and fully analyzed prior to proceeding further with identifying a preferred alternative. This Scope of Work (SOW) will confirm, refine and evaluate, where needed, the four water supply alternatives presented in the July 2012 TM. In addition, as per the recommendation from the TM, this SOW will further examine potentially practicable alternatives for meeting the County's overall future needs, including alternate water sources (i.e., surface water, groundwater, or other appropriate naturally occurring sources, and other techniques to enhance, sustain, or optimize the naturally occurring sources (e.g., water conservation, use of reclaimed water, water supply systems interconnections, artificial recharge of aquifer.)) A key component of this SOW will be to analyze water supply alternatives in order to apbropriately capture all effects (economic, environmental and social) associated with plan selection leading implementation by OCWS. Article B. Scope of Services Task 1- Define Range of Water Supply Alternatives Given the on-going concerns regarding the sustainability of Floridian aquifer groundwater production along the coast, the draft 2013 water supply alternatives (WSA) from the NWFWMD notes that future demands may be met through development of alternative inland groundwater or surface water sources and that the NWFWMD will continue to evaluate alternative sources under the Regional Water Supply Plan (RWSP) including surface water, expanded use of the sand and gravel aquifer, conservation, and reuse. In light of these recent revisions, there is a need to further define the appropriate methodology for the evaluation of the alternatives with the intent of building on the existing TMs prepared to date. In conjunction with tasks to be completed by the U.S Army Corps of Engineers Mobile District {(USACE), CH2M HILL will assist the COUNTY to further define the appropriate methodology for t
