IRC SWDD shall define their requirements (location, facilities, configuration, etc.). <br />Subtask 1.2 Data Collection and Review <br />CDM will review and compile available information related to the project including the <br />following: <br />■ Available information on existing utilities. <br />■ Existing environmental studies. <br />■ Available traffic studies. <br />■ Historical aerial photographs. <br />■ Existing site geotechnical, geologic, and hydrogeologic reports including geologic <br />studies, well logs and stratigraphic descriptions, hydrological studies, and existing <br />geotechnical reports, if available. <br />■ Existing survey data and photographic information for the Oslo Convenience <br />Center, that was recently performed by Carter Associates, Inc. IRC has detailed <br />topographic information and a recent aerial photograph delineating the project <br />boundaries. If CDM determines that additional survey or photographic information <br />is needed, any additional survey or photographic information will be provided as <br />additional service to this contract. <br />■ Existing permits and previous permit submittals. <br />Subtask 1.3 - Preliminary Site Plan <br />The Oslo Convenience Center is located at a closed landfill. Existing information obtained in <br />Task 1.2 will be used to estimate the limits of waste areas, existing asphalt pavement, stabilized <br />limerock, and compacted natural soil. A preliminary site plan will be developed for use in <br />preapplication meetings with Regulatory agencies. The site plan will include layout of the <br />access road and the future facilities which will be needed, such as proposed buildings and a <br />Stormwater detention pond. The preliminary site plan will be based on information obtained <br />during the IRC SWDD meeting (Task 1.1). <br />A-2 Ibi%6 Coc <br />
