Re: Proposal to Analyze Highway Noise Berm in Avon, Colorado
Dear Ms. Strehler,
Per you request, the following is a proposal to have Hankard Environmental conduct highway
noise measurements and analyses for a proposed berm along Interstate 70 (1-70) in Avon,
Colorado. Our analysis will determine existing noise levels (no berm), noise levels after the
berm is constructed, and the amount of noise reduction that will be provided by the berm. We
will provide a report that will document the different acoustical quantities that the Colorado
Department of Transportation (CDOT) requires. The following provides a description of our
qualifications, a scope of work, schedule, and cost.
QUALIFICATIONS
Hankard Environmental has been conducting noise studies in Colorado for over 15 years. We
have analyzed dozens of highway noise issues for CDOT, as well as for local agencies,
developers, architects and homeowners. We are very familiar with the 1-70 Mountain
Corridor and have conducted a variety of noise measurements and studies within the area,
including Vail, Eagle-Vail, Eagle, and Cordillera. Hankard Environmental has conducted
extensive highway noise measurements in the Vail Valley, as well as analyzed barriers and
berms using the Federal Highway Administrations Traffic Noise Model (TNM) software
program. We have gained a great deal of respect for our analyses throughout the CDOT
organization. Please refer to www.hankardinc.com for additional information.
SCOPE OF WORK
TASK 1 - Analyze the Effectiveness of the Proposed Berm: We will construct a software model
of the project site, validate the model by comparing its output to measured noise levels, and
use the model to predict the effectiveness of proposed berm design(s). Specific work tasks
include:

ENVIRONMENTAL
ZEE __~=-s = a==a_-_
Accuse cs nNO VIRRA-ION C045LLTING
■ Gather project design data, including proposed topography, site layout, existing and
future traffic data, etc.
■ Conduct short-term noise measurements on the project site. This includes measuring
both traffic noise levels and monitoring the corresponding traffic conditions for the
purpose of validating a noise model of the site.
• Construct a Traffic Noise Model (TNM) of the site and use the model to predict the
traffic noise level at sensitive locations (residences, schools) for existing conditions and
for various berm alternatives. Predicted levels will be compared to CDOT standards.
■ Analyze the effectiveness of noise mitigation. Noise barriers will be analyzed using
TNM, and a recommended length and height of the barrier will be provided along
with the preferred location (unless already specified).
■ Document results in a report. A report will be provided that provides all the necessary
technical details and results with the intent that it will be submitted to CDOT for their
use is reviewing the proposed berm.
TASK 2 - Conduct Long-Term Noise Measurements: Long-term (-one week) noise
measurements are the best way to describe existing highway noise levels. They clearly show
how traffic noise levels fluctuate over the course of the day and night. While these
measurements are not necessary in order to comply with CDOT requirements, this data is
very useful from the standpoint of justifying the project. Specific work tasks include:
■ Install three long-term noise monitors on site.
■ Recover, download, plot, and analyze noise measurement data for each site.
■ Document the results in a report. This would include all necessary technical details
such as the measurement locations, equipment used, and a graphical display of the
results.
TASK 3 - Attend Meetings and/or Hearings: We are available to attend design meetings,
agency meetings, etc., as needed.
SCHEDULE AND AVAILABILITY
We can complete Tasks 1 and 2 within four weeks of receiving a written notice-to-proceed.
Delays to this schedule can occur due to inclement weather and/or to delays in receiving
requested data (such as mapping and traffic volumes).

COST
All work can be completed on a fixed-price or time-and-materials basis. The estimated cost for
Task 1 is $5,500. The estimated cost for Task 2 is $3,900. The estimated cost for Task 3 is
around $500 per on-site meeting. Each estimate includes all labor, expenses, and
measurement equipment rental. A majority of this work will be completed by Mr. Jeff Cerjan,
who has over 10 years of direct experience in highway noise measurement and analysis. Our
