� �CPgCADES...-TO THgOOLL�i �40 °f9 KITTITziS COUNTY - DEPARTMENT OF PUBLIC WORKS HITTITAS COUNTY If Ecology deems the 2015 technical work unsuitable to use for the proposed permit application, then Aspect will complete a comprehensive technical memorandum including all of the components listed in the Phase 1 CRA contract. These components include: • Describe the hydrogeologic conceptual model of the proposed project site. This needs to include but not limited to 1) Identify and describe the aquifer properties of the source aquifer. 2) Identify source aquifer boundary conditions. 3) Identify water level trends in the source aquifer. 4) Estimate the water budget for the source aquifer. • Describe the physical and legal availability of water in the proposed project areas. • Impairment Analysis - Identify all senior water rights and yet-to-be-processed senior water right applications within the same source aquifer. Identify and quantify impacts to senior water rights in the source aquifer. • Identify and quantify impacts to surface water bodies and tributaries • A site map showing the place of use and point(s) of withdrawal for all related water rights, ensuring clarity on project boundaries and infrastructure. • A vicinity map showing the location of all senior water rights and any senior water right applications within the same source aquifer,providing context to their proximity to the proposed project. • A groundwater elevation map showing groundwater elevation contours based on area well reports and published source material. This map should clearly depict all surface water features, as well as assumed groundwater divides,to illustrate the relationship between groundwater and surface water bodies. • A geologic cross section based on available area well reports and published source material, showing the subsurface conditions relevant to the proposed project. Budget under this task will be largely dependent on Ecology's feedback on the Phase 1.1 deliverable. If the Phase 1.1 deliverable is not accepted Aspect cannot predict the level of effort that Ecology will require for Phase 1.2. We have prepared this scope based on similar assessments performed in the past and will advise the County of progress as key milestones are reached in the scope above in the event unforeseen issues arise. Under Phase 1.2 Aspect has budgeted for up to 2 virtual meetings with Ecology and or the County. Phase 2.1 Draft Report of Examination and Public Notice ($13,500) Under this Phase,Aspect will prepare the permitting documents required under Phase 2 of the CRA. These documents include the draft Report of Examination, the public notice, and the draft
