Project Description:
The City of Roswell planned a 30 acre park along the Chattahoochee River
just north of Atlanta. To lessen the environmental impact on the ecologically
sensitive Chattahoochee, the city chose to utilize pervious paving for a
portion of the parking for the facility. The main entrance to the project
and a portion of the parking area nearest the buildings was to be conventional
asphalt paving. Design of both the pervious paving and the conventional
paving was complicated by the presence of a layer of soft alluvial soil
that lay beneath much of the site.
Project Achievement:
The conventional approach to constructing paving over soft soil in the
project area is to remove several feet of the soft material and replace
it with stone ranging from three to five inches in diameter. This approach
was not only cost prohibitive, it was considered environmentally unsound
due to the proximity of the river. A system capable of supporting the
conventional pavement with a minimum of soil removal and capable of
providing a pervious pavement system was needed. Ultimately, the design
team chose the Geoweb® Cellular Confinement System due to its ability to
serve both of these functions.
The area was stripped of topsoil and minor grading was performed to ensure
positive drainage. A geotextile fabric was placed as a separation layer
between the poor subsoil and the infill material. After the Geoweb®
sections were expanded and secured, tendons were laced through the sections
and secured with stakes to prevent uplift. Crushed granite was then dumped
into the sections and spread using small equipment. A layer of
coarse sand was placed over the infilled Geoweb® sections in the pervious
pavement areas. Asphalt was placed directly on top of the infilled Geoweb®
sections in areas to receive conventional paving.
The park is set to open in the Fall of 2002 and will stand as an example
of how low impact development can be accomplished in a cost efficient manner.
