RE: Oak Brook ITEP Application Narrative
Project No.: 03- 0745- 004 -01 -01 B
The proposed improvements outlined in this application are a step towards Oak Brook Illinois' long -term vision
to improve the quality and image of its public streetscapes, consistent with the Village's Streetscape
Beautification Masterplan. This Masterplan prescribes specific strategies and standards for streetscape
improvements that can be constructed in phases over time and yield a consistent quality appearance for the
community
The target area for these ITEP funds is a one mile stretch of Illinois State Route 83 between 22nd Street to 31"
Street in Oak Brook. This portion of road is a mayor Village thoroughfare with heavy traffic volumes, and thus,
heavy exposure to residents and visitors alike. The impact of the proposed improvements would do a great deal
to enhance the appearance of adjacent land -uses and the quality of the commuting experience on this arterial
corridor.
The existing site consists of a four -lane 45 to 55 mph road with the only intersection between 22nd Street and
31" Street being an interchange with Interstate 88. The vehicular paving is in good condition. There is a paved
median separating north and south bound traffic Lighting is adequate for nighttime traffic flows. Pedestrian
use is not encouraged on site due to high traffic speeds, lack of intersections for safe crossing, and lack of
access to adjacent land -uses. Due to these existing site conditions, the project's design team chose to focus
improvements on landscape material at the sides of Route 83 and areas around interchanges
Due to the project site having predominately commercial adjacent land -uses to the north and predominantly
residential land -uses to the south, the proposed improvements would utilize both "ornamental" and
"naturalized" planting styles, which is consistent with Oak Brook's Streetscape Beautification Plan. The
ornamental planting style near the commercial areas would utilize trees, shrubs, and perennial flowers in a
systematic fashion to achieve a "planned, manicured" appearance. The naturalized planting style near the
residential areas would utilize native plant species organized in a more random fashion in order to mimic the
native landscapes of Illinois. These two planting styles would be smoothly transitioned along the length of the
roadway to allow for a smooth aesthetic progression. The plant material quantities represented in this
application provide a balance between bold aesthetic impact and restrained fiscal consciousness
In summary, Oak Brook's proposed improvements to Illinois Route 83 as outlined in this application are part of
a carefully outlined masterplan to enhance the appearance and experience of the community as a whole while
traveling the Village's roadways These improvements are of an appropriate scale to create a noticeable
positive visual impact while being sensitive to the surrounding context and reinforcing a positive community
image along one of the Village's most traveled corridors.
