4 Project Description A tree survey to identify species, size, health and structure was conducted by Quigg Engineering Inc. (QEI) personnel on September 2 and 3 of 2015, in Sugar Grove, Illinois along Illinois 47 and I-88 from Green Road to the north entrance of Waubonsee College; and 3000 feet east and west of Illinois 47 along I-88. This survey was conducted for Illinois Department of Transportation (IDOT) and Illinois State Toll Highway Authority (ISTHA). Methodology Trees were surveyed using a transect method, with information collected on the species, size (Diameter Breast Height (DBH)), health, structure and origin (landscape or volunteer). QEI chose ten locations based on aerial imagery that provided a representation of the trees and plant community of the project area. These locations were pre-approved by IDOT District 1. Each transect was 100 feet long and approximately 20 feet wide. A tree is defined by the Illinois Department of Transportation Bureau of Design and Environment (BDE) Manual Chapter as a woody perennial plant having a single main stem (trunk), the diameter of which is 6 in (150 mm) or more at a point 4.5 ft (1.35 m) above the highest ground level at the base of the tree. The term tree also includes woody perennial plants having a single trunk of less than 6 in (150 mm) in diameter where such plants have been intentionally planted for landscaping, environmental mitigation, or habitat preservation/enhancement. A landscape tree is defined as any tree planted as a seed or sapling in a managed area and maintained by human actions. A specimen tree is defined as those on the inventory of state record trees; those that are outstanding examples possessing exceptional size, form, etc.; or those having a recognized historical significance. The health and structure of the surveyed trees were categorized and each category was given a corresponding number: good (4), fair (3), poor (2), or dead (1). Ratings for health are based on the extent to which a tree is reasonably free of signs and symptoms of disease. Ratings for structure are based on the extent to which a tree has a structure and form typical of the species as defined in (BDE) Manual Chapter Two QEI employees were tasked with performing the tree survey. The survey began on September 2, 2015 on the southeast end of the project corridor, north of Old Oak Road and continued along the east side of Illinois 47 north to Green Street. The following day, September 3, 2015 the survey continued, starting on the northwest end of the project corridor and continued south along the west side of Illinois 47 south to Old Oak Road (See Figure 1). Limitations of Survey Each tree was inspected visually by a QEI biologist during the tree survey. However, tree health is not always visible on the surface. It is believed that the health is accurate based on the outward appearance of the tree, but there may be health problems that were not visible on the surface of the tree. Therefore, this survey does not guarantee the health of any trees in the survey. 2

5 Tree Evaluation Ten locations within the project corridor were surveyed in order to obtain cover type characteristics for trees. Cover types sampled included upland forest, floodplain forest, shrubland, and urban/built-up land. The upland forest consisted of Mockernut Hickory (Carya tomentosa), Black Cherry (Prunus serotina), and Oak species (Quercus sp.). The floodplain forests consisted of primarily Box Elder (Acer negundo). Shrubland consisted of Green Ash (Fraxinus pennsylvanica), Siberian Elm (Ulmus pumila), and Black Walnut (Juglans nigra). Urban/built-up land consisted of White Oaks (Quercus alba), Blue Spruce (Picea pungens), and Mockernut Hickory (Carya tomentosa). Figure 2 indicate the trees surveyed within each transect. Ash trees observed along the corridor were generally in poor health. Emerald Ash Borer holes were present in several of the trees.
