B-4 Providing Relevant and Helpful Support Documentation
If you answered "yes" to Section B, Question 1 of the PDM Environmental and Historic Preservation Questions, there are several important items to attach to your application as support documentation.
First, include a detailed narrative describing the extent of ground disturbance both in the scope of work, and in the comments box in Section B of the Environmental and Historic Preservation questions. The narrative should include where the project is located, the boundaries of the project area, what kinds of activities will take place in the project area, and how much ground is going to be disturbed. Example:
The piping will be installed next to Johnson Road from Main Avenue north to 12th Street. All work and excavation will be performed from the hardtop surface of Johnson Road, or within its 15 foot right-of-way. Excavated soils will be temporarily stored adjacent to the trench until the piping is installed. Excess excavated material will be taken to the county sand pit. The roadside will be excavated using a Cat 416 backhoe. The trench will be approximately 6-feet wide and 5-feet deep. The piping will be installed at the bottom of the trench, backfilled, and then roller compacted using an Ingersoll-Rand R-194 compactor.
Second, include a narrative of current land use and all known historical uses of the project area in the comments box in Section B of the PDM Environmental and Historic Preservation Questions. Example:
The road has been at this location for approximately 60 years, and before that it was a dirt road primarily used by farmers in the area. Land use in the project area consists of residential housing that was built after WWII. In the project area, the right-of-way of the road also contains buried gas and electric line utilities.
Third, provide a narrative describing the extent of previously disturbed ground. Previously disturbed ground means that some type of ground disturbing activity has taken place in an area, and that this activity may have affected the integrity-or intactness-of archeological resources present at a site. For example, if a road has been graded and paved through a site, the right-of-way for the road is considered to have been previously disturbed. Previous disturbances, however, do not necessarily destroy the integrity of a site; the degree of disturbance depends on the context of the activity. For instance, a farm field that has been plowed for 50 years may have lost integrity in the top 2 or 3 feet of soil, but retains integrity below that depth.
Fourth, in addition to the comments you provide in the scope of work and Section B of the Environmental and Historic Preservation questions, attach a copy of a 1:24,000 USGS topographic map [example SHPO map] to your application indicating:
- the project site
- the location of any ground disturbing activities, including excavation, the operation of equipment or staging or borrowing areas
- the location of any known archeological sites
Fifth, documentation of your contact with the relevant SHPO/THPO, including:
- scanned and attached copies of response letters, faxes, or emails
- summaries of relevant telephone conversations
- the status of any outstanding correspondence
Lastly, if it has been determined that that the project site contains archeological sites, or has a high potential for archeological resources, include with your application a discussion how adverse effects to these resources will be avoided, minimized or reduced, or compensated for.
