Root Investigative Study Report Objectives: Determine growth characteristics of representative tree species in Loudoun County, VA by means of investigative digging in representative species, soils and hydrological regime. The results of this Study are used to determine strategies in design and construction as well as prescribe appropriate protection measures & stress reduction therapies. Beginning Supersonic Airtool (SSAT) Investigation within proposed roadway selecting representative tree species: White Oak, Red Oak, Hickory, Ash.
Note roots are very near surface. This is not characteristic of white oaks in Montgomery County MD Piedmont in loamy clay mica rich soils. Deeper restrictive layers are assumed to be the reason. Refer to soils boring reports for verification.

Several locations at the Pennsylvania State Capitol South Park were identified with trees which are having potential design elements installed or renovated within their Critical Root Zones (CRZs) with potential for major impacts. These design elements are storm drain pipe and infiltration beds, concrete steps, electric site light conduits, retaining walls, water lines, and walk demolition and reconstruction.
