previous environmental site assessment <strong>of</strong> this project should be included in this section. This<br />

section should also include a list <strong>of</strong> sites requiring Phase I ESAs and the rationale. This rationale<br />

is generally taken directly from the ESA Screening. For projects with a large number <strong>of</strong> sites, this<br />

list may be tabularized and should indicate the address, parcel number, and stationing, if available.<br />

7.1.3 Geographical/Geological Setting <strong>of</strong> the Project Study Area<br />

Information regarding the physical setting <strong>of</strong> the project study area or corridor should be included in<br />

this section. The report should include information about geographical and general geological<br />

features. This information is meant to be general and not parcel-specific; however, should there be<br />

local deviations in the geology for the project area, they should be documented. Information such<br />

as soil type, regional bedrock, surface drainage, topography, ground water usage, etc., should be<br />

included in the report. In addition, the report should include a USGS 7.5 minute topographic map<br />

with the quadrangle name and project limits indicated.<br />

7.1.4 <strong>Site</strong>-Specific Information<br />

The All Appropriate Inquiry Rule does not specify sources <strong>of</strong> land use history. Historic resources<br />

vary greatly across the nation. However, based on ODOT’s experience conducting environmental<br />

site assessments since 1988 and researching historical architecture for projects, the following<br />

resources are available for the majority <strong>of</strong> the state. This objective data are <strong>of</strong> great value in<br />

determining land use and potential source areas. If a data gap occurs for any <strong>of</strong> these sources, the<br />

attempts taken to obtain this information shall be explained in the report.<br />

7.1.4.1 <strong>Site</strong> History<br />

Historical land use information must be reviewed for each property and documented in the<br />

report to assess the potential for the presence <strong>of</strong> regulated materials on a site. A chronology<br />

should be provided for each parcel indicating the address, owner and/or lessee, the use or<br />

business, and a date or date range <strong>of</strong> the usage. Historical land use research should be traced<br />

to the earliest date <strong>of</strong> development. The earliest date <strong>of</strong> development is used since many<br />

industrial and manufacturing sites started in the mid to late 1800’s and have been redeveloped<br />

into other uses over time. Information gathered from this research should be examined in order<br />

to draw clear conclusions and recommendations about the historical land use for each site.<br />

The following sources, at a minimum, must be reviewed:<br />
