Hydrogeology Investigation Experience <br />Flett Creek Watershed Strearnflow Restoration Grant; Pierce County, WA. LAI assisted the City of <br />Tacoma with a Streamflow Restoration Grant (Application ID: WRSRP-2020-TacoES-00004) to Ecology to <br />conduct a feasibility study to enhance streamflow in the urban Flett Creek watershed for the purpose of <br />supporting robust and healthy salmon <br />populations. LAI was hired by the City tod� <br />prepare the grant application. An .15 3 <br />application requirement was to estimate <br />q .

The grant was awarded and LAI has been hired by the City to conduct the feasibility study, <br />which will evaluate potential streamflow benefits in the historical Flett Creek floodplain incorporating <br />multiple project types: water storage (improved stormwater infiltration and management); watershed <br />function, riparian and fish habitat improvements; and environmental monitoring elements. The first <br />phase of the project is to conduct a feasibility study to evaluate the potential for aquifer recharge, <br />stormwater management, and streamflow restoration at three sites, document water availability, <br />identify permitting requirements and other potential constraints, and develop preliminary design and <br />costs for overall project implementation. LAI staff Eric Weber and Kelsey Mach. <br />City of Spokane Havana Street Wellfreld; Spokane, WA. EAI recently provided hydrogeologic and <br />geotechnical engineering services to the City of Spokane for development of its Havana Street wellfield, <br />a project intended to expand the capacity of the City's groundwater supply system. <br />The project included site assessment, design, testing, and construction of a new well field to supplement <br />the City's existing system. LAI initially provided technical consulting services to the City for a preliminary <br />assessment of the potential well site <br />hydrogeology followed by site- <br />specific field Investigations to <br />characterize environmental and <br />hydrogeologic conditions that were <br />used to develop preliminary <br />recommendations regarding the <br />site's suitability for a new water <br />supply. LAI subsequently completed <br />additional assessment of geologic <br />and hydrogeologic conditions during <br />construction of a pilot test well, <br />completed aquifer testing during a <br />Landau Associates [ 4 i Statement of Qualifications <br />
