Burk-Kleinpeter,
Inc. (BKI) was commissioned by the
Louisiana Department of Transportation and
Development (DOTD) to develop noise
barrier design and landscaping layouts for
11 miles of the I-10 corridor within the
New Orleans metropolitan area. This study
was an outgrowth of the Noise Mitigation
Planning and Conceptual Engineering for
Route I-10. Loyola Drive - Tulane Avenue
also conducted by BKI. The previous study
established the location and height, but
did not deal with landscaping or barrier
design.
The work was
partially accomplished through an
evaluation of information gathered from
the previous reports, input given by an
independent Design Committee, and through
information acquired from various
Departments of Transportation, product
vendors, and site visits.
The goal of this
project was to develop selected alternative
ground-mounted (at grade) noise wall facade design
concepts and to evaluate the feasibility of
landscaping the I-10 project corridor. The study
accomplished the following:
- Developed
alternative design concepts for noise barrier
surface designs with standardized heights of
16', 20' and 24'.
- Determined
where landscaping improvements can occur along
I-10.
- Established
general landscaping zones and recommended
appropriate alternative plant materials for each
zone.
- Developed
general magnitude cost estimates for $27.0
million of recommended ground mounted noise
walls, and $2.3 million for landscaping
improvements.
- Established
general maintenance guidelines for the noise
wall panel segments and landscaping
improvements.
- Established
guidelines for development of noise wall and
landscaping construction specifications for the
noise barriers throughout the entire 11-mile
long corridor.
