EXHIBIT A
SCOPE OF WORK
Review of Existing Conditions:
BBA will review the available noise level and operational data which describe existing
conditions at each airport. We will visit each airport, and will confer with airport management,
fixed base operators and Caltrans to describe existing aircraft operations, including aircraft.
types, flight tracks, runway use and -time of day of operations. Based upon the review of
available data, BBA will identify any additional data needs, and will report upon those needs
to the County before establishing the operational assumptions.
Aircraft noise measurements are useful to confirm the accuracy of noise modeling, and to
establish the credibility of the noise modeling process with affected residents. We recommend
that, at Ranchero Airport, noise level measurements be conducted at four locations in the
airport environs to characterize single event and cumulative noise levels for- existing conditions.
We will perform the noise measurements over a one-week period at sensitive receiver
locations where we can readily apply the noise level data to validation of the INM. BBA staff
will observe aircraft operations and document single event noise levels over two 8 -hour
periods during the measurement period..
2. . Prediction of Existing Aircraft Noise Levels:
To predict existing aircraft noise levels, -BBA will use Version 5.01 of the FAA's Integrated
Noise Model (INM). This version of the INM incorporates slant range distance corrections
based upon CD-ROM files of local topography. We anticipate that the default INM data base
will be used, except that we may make modifications to account for unusual flight procedures
or aircraft types. BBA will prepare a suitable data base for helicopter operations, which are
not included in the current version,of the INM.
BBA will prepare a noise exposure map depicting the locations of the 55, 60, 65 and 70 dB
CNEL contours for existing operations at the Paradise and Ranchero Airports. The noise
exposure maps will be plotted on 11" by 17' paper at an'appropriate scale according to your
needs. BBA will provide the map in ARCINFO format, if this is not possible, AutoCAD -format
may be substituted.
For Ranchero Airport, -BBA will prepare grid point analyses for the four noise measurement
sites used for Task 1 to describe predicted single event noise levels and Time Above values.
BBA will describe the differences between measured and predicted noise levels, and will
analyze the reasons and significance of any differences. The noise analysis will assess the
significance of cumulative noise levels, single event noise, levels, and Time Above values,
based upon current FAA practices.
3. Reports:
BBA will prepare a technical report for both the Paradise and Ranchero Airports describing
the assumptions and methods used to prepare the noise exposure maps. The report will
summarize the findings and conclusions developed in Tasks 1 and 2, describing anticipated
public response and environmental significance as defined by the California Airport Noise
Regulations and FAA FAR Part 150 guidelines.

RE: Creation of aviation noise studies for Paradise Airport and Ranchero Airport.
Dear Paul,
The Butte County Airport Land Use Commission has be
gun a d Use
Plans (CLUPs) for two public use airports in the Countyd rantic antieview of cipates these ten prehensive
year old
documents in the coming months. It is this updating process that will require new noise studies to
be completed.
Paradise Airport, located approximately two (2) miles south of the Town of Paradise, is in a
predominantly rural residential area without any significant noise constraints. Ranchero Airport is
located on the western edge of the City of Chico and has been substantially encroached upon from
the east and north by medium density residential development. This encroachment has resulted in a
great number of noise complaints and the alteration of flight patterns. Rancheroalso conducts
helicopter flight training with its accompanying complaints.
The noise studies that are necessary should include a discussion of terms and methodology, the
development of contours, differences between CNEL and SNEL patterns, and graphic presentations
for inclusion in the CLUP's. The ALUC is hopeful that the requested studies can be completed
quickly and be presented to them at the regularly scheduled July 17, 1996 meeting.
Any suggestions from your firm as to the content and format of such studies would be appreciated.
Any information that I can provide that will assist your efforts will be promptly provided. I look
forward to your response.

Brown=Buntin Associates, Inc. (BBA) is pleased to submit the following proposal to prepare CNEL noise
exposure maps -and technical reports for the Paradise and Ranchero Airports in Butte County, California. BBA
proposes to perform the following tasks:
1. Review of Existing Conditions: _.
BBA will review the available noise level `and operational data which describe existing
conditions at each airport. We will visit each airport, and will confer with airport management,
fixed base operators and Caltrans to describe existing aircraft operations, including aircraft
types, f it ght tracks, runway use and time of day of operations. Based upon the review of
available data, BBA will identify any additional data needs, and will report upon those needs
to the County before establishing the operational assumptions.
Aircraft noise measurements are useful to confirm the accuracy of noise modeling; and to "
establish the credibility of the noise modeling process with affected residents. We recommend
that, at Ranchero_ Airport, noise level measurements be conducted at four locations in the
airport environs to characterize single event and cumulative noise levels for existing conditions.
We will perform the noise measurements over a one-week period, at sensitive receiver
locations where we can readily apply the noise level data to validation of the INM. BBA staff.
will observe'aircraft operations and document single event, noise, levels over two 8 -hour
periods duping the measurement period.
2. Prediction of Existing Aircraft Noise Levels:
To predict existing aircraft noise levels, BBA will use Version 5.01 of the FAA's Integrated
Noise Model (INM). This version of the INM incorporates slant range distance corrections
based upon CD-ROM files of local topography. We anticipate that the default INM data base
0-_. , .
will be used, except that we may make modifications to account for unusual flight pprocedures -
��` or aircraft types. BBA will prepare a suitable data base for helicopter operations, which ra e
O'l�Llc°rn�r2 not included in the current version of the .INM.
BBA will prepare a noise exposure map depicting the locations of the 55; 60, 65 and 70 dB
CNEL contours-for`existing'operations aat"the Paradise and Ranchero Airports. The noise
exposure maps will be plotted on 11" by 17' paper at an appropriate scale according to your
Z>4„r needs. 1f needed, BBA will provide the map in AutoCAD format. NAV/

For Ranchero Airport, BBA will prepare grid point analyses for the four noise measurement
sites used for.Task 1 to describe predicted single event noise levels and Time Above values.
BBA will describe the differences between measured and predicted noise levels, and will ?-
analyze.the`reasons and significance of any differences. The noise analysis will assess the
significance of cumulative noise levels; "single event noise levels,'and Time Above values,
based upon current FAA"practices. _
3. Reports:
BBA will prepare a technical report for both the Paradise and.Ranchero Airports describing
the assumptions and methods used to prepare the noise exposure maps. The report will
summarize the findings and conclusions developed in Tasks 1 and 2, describing anticipated
public response and"environmental significance as defined by the California Airport Noise"
Regulations and FAA FAR Part 150 guidelines.
Mr. Jim Buntin will serve as Project Manager for BBA on this project. Professional staff work will be provided
by Mr. Paul Bollard. The project_will be managed from our office in Fair Oaks, California. ;
We anticipate performing the above tasks in approximately six weeks, assuming that all pertinent operational'
data and assumptions are made available to us in a timely manner.
r
Brown-Buntin Associates, Inc. will perform the services described above for a total fee of $10,500, based upon
the attached fee schedule. Attendance at one public meeting is included in this fee-. Attendance at other
meetings or hearings will be.provided on a time and expenses basis in accordance with the attached fee
schedule. if the noise measurement program at Ranchero Airport were deleted from the scope of work, the
fee would be reduced to $7,500.
Terms of payment are normally payment in full due 30 days from the time of delivery of completed documents.
I hope that this proposal meets you needs at this time. We are looking forward to the possibility of working with
you on this project. Please call me in Fair Oaks at (916-961-5822 if you have any questions concerning this
proposal.
Sincerely,
Brown-Buntin Associates, Inc.
