The budget for this task assumes two members of GeoEngineers attending up to five meetings, each lasting up to 1 hour. $3,300 -- 2500 Phase II Environmental Site Assessment (ESA ) Scoping Includes identifying and planning the scope of work and developing associated investigation cost estimates for conducting Phase II ESAs for the parcels identified for redevelopment as part of the EOMS Project. $5,500 -- 2600 Phase II ESA Includes conducting field work (i.e., advancing borings and collecting soil and groundwater samples), laboratory analysis, data interpretation and reporting to evaluate the potential presence of hazardous chemicals in soil and groundwater at the parcels within the project area. $150,000 Assumes that field work will be performed after buildings have been demolished. Estimated costs are preliminary and may be refined based on the results of the Phase I ESA. 2700 Contaminated Materials Management Planning Includes conducting additional field work to further characterize the nature and extent of impacted soil and groundwater within the project area, coordinating with Bayley and the design team to develop a strategy for managing impacted soil and groundwater during redevelopment activities, and preparing a Contaminated Media Management Plan (CMMP)to guide contractors during excavation and construction. $80,000 Estimated costs are preliminary and may be refined based on the results of the Phase II ESA and civil design. Does not include costs for excavation, transport, and disposal of impacted soil or addressing other environmental conditions (e.g, underground storage tanks, UICs, wells, etc.). 2800 Environmental Construction Oversight Includes onsite support to manage impacted soil and groundwater during construction activities $110,000 Estimated cost is preliminary and may be refined based on the findings from task 2700. 2900 Contaminated Materials Management Reporting Includes preparing a report describing the handling, management, and disposal of impacted soil and groundwater during excavation and construction. $20,000 Estimated cost is preliminary and may be refined based on the findings from tasks 2700 and 2800. 3000 Regulatory Agency Coordination Includes initial coordination with the Department of Ecology for excavation at parcels that are registered cleanup "Sites".$10,000 Estimated cost is preliminary and may be refined based on City of Everett's strategy for management of environmental risk. 3100 Remedial Investigation (RI)Includes conducting additional environmental investigation activities as necessary to satisfy Ecology requirements for evaluating the nature and extent of contamination at the parcels that are registered cleanup "Sites". $100,000 Estimated cost is preliminary and may be refined based on City of Everett's strategy for management of environmental risk and environmental conditions at the Sites. 3200 Prepare a RI/Feasibility Study/Draft Cleanup Action Plan Includes preparing a report describing the results of RI, presenting an evaluation of feasible alternatives to address impacted soil and groundwater, and describing a proposed approach for addressing impacted soil and groundwater at the registered cleanup "Sites" $80,000 Estimated cost is preliminary and may be refined based on City of Everett's strategy for management of environmental risk and environmental conditions at the Sites. 3300 Cleanup Action Includes implementation of a Cleanup Action consistent with the Ecology-approved Cleanup Action Plan.To be Determined Estimated costs will be determined based on the findings from task 3100. $388,700 Estimated cost is preliminary and does not include task 2800. $190,000 Estimated cost is preliminary and Does not include task 3300.
