Dear Ms. Beck:
Freese and Nichols, INC. (FNI) is currently under contract for the engineering of the above-referenced

modeling analysis effort. Below are a few areas where additional effort was provided:
1. Hydraulic Modeling Analysis
a. FNI geocoded the proposed developments in the Hickory Creek basin based on the
address provided by the City.
b. FNI developed mapping presenting the extents of the Hickory Creek Interceptor and the
location of the proposed developments and provided to City staff for review.
c. FNI revised the proposed developments based on City staff comments.
d. FNI reviewed the hydraulic wastewater model provided by the City.
e. FNI reviewed how the proposed Hickory Creek Peak Flow Storage Facility is modeled
compared with the design flow rate.
f. FNI created five modeling scenarios representing different demand conditions and
wastewater infrastructure improvement.
g. FNI imported the proposed developments in the Hickory Creek Basin into the model.
h. FNI coordinated with the design group responsible for the Hickory Creek Interceptor
Phase I/II to update the model with the proposed improvements.
i. FNI georeferenced plans for the Hickory Creek Interceptor Phase III/IV and the Dry Fork
Interceptor and imported the improvements into the model.
j. FNI met with City staff to discuss updates on the Hickory Creek Interceptor Analysis.
k. FNI created profiles presenting the results of the hydraulic analyses.
l. FNI created figures as part of the Hickory Creek Interceptor analyses.
m. FNI determined which manholes along the Hickory Creek Interceptor that would need to
be bolted down in order to allow for additional capacity for proposed development.
n. FNI met with City staff to discuss updates on the Hickory Creek Interceptor Analysis.
o. FNI developed a comprehensive summary of analysis for presenting to City leadership.
p. FNI presented the results of the analysis to City leadership.
q. FNI met with City staff to discuss updates on the Hickory Creek Interceptor Analysis.

$1,009,980.43.
We hope this letter provides the necessary summary of the additional engineering services incurred.
We look forward to helping the City of Denton complete this project. Please call with any questions or
concerns.
Sincerely,

ELECTRONIC RECORD AND SIGNATURE DISCLOSURE
From time to time, City of Denton (we, us or Company) may be required by law to provide to
you certain written notices or disclosures. Described below are the terms and conditions for
providing to you such notices and disclosures electronically through your DocuSign, Inc.
(DocuSign) Express user account. Please read the information below carefully and thoroughly,
and if you can access this information electronically to your satisfaction and agree to these terms
and conditions, please confirm your agreement by clicking the 'I agree' button at the bottom of
this document.
Getting paper copies
At any time, you may request from us a paper copy of any record provided or made available
electronically to you by us. For such copies, as long as you are an authorized user of the
DocuSign system you will have the ability to download and print any documents we send to you
through your DocuSign user account for a limited period of time (usually 30 days) after such
documents are first sent to you. After such time, if you wish for us to send you paper copies of
any such documents from our office to you, you will be charged a $0.00 per-page fee. You may
request delivery of such paper copies from us by following the procedure described below.
Withdrawing your consent
If you decide to receive notices and disclosures from us electronically, you may at any time
change your mind and tell us that thereafter you want to receive required notices and disclosures
only in paper format. How you must inform us of your decision to receive future notices and
disclosure in paper format and withdraw your consent to receive notices and disclosures
electronically is described below.
Consequences of changing your mind
If you elect to receive required notices and disclosures only in paper format, it will slow the
speed at which we can complete certain steps in transactions with you and delivering services to
you because we will need first to send the required notices or disclosures to you in paper format,
and then wait until we receive back from you your acknowledgment of your receipt of such
paper notices or disclosures. To indicate to us that you are changing your mind, you must
withdraw your consent using the DocuSign 'Withdraw Consent' form on the signing page of your
DocuSign account. This will indicate to us that you have withdrawn your consent to receive
required notices and disclosures electronically from us and you will no longer be able to use your
DocuSign Express user account to receive required notices and consents electronically from us
or to sign electronically documents from us.
All notices and disclosures will be sent to you electronically
Unless you tell us otherwise in accordance with the procedures described herein, we will provide
electronically to you through your DocuSign user account all required notices, disclosures,
authorizations, acknowledgements, and other documents that are required to be provided or
made available to you during the course of our relationship with you. To reduce the chance of
you inadvertently not receiving any notice or disclosure, we prefer to provide all of the required
notices and disclosures to you by the same method and to the same address that you have given
us. Thus, you can receive all the disclosures and notices electronically or in paper format through
the paper mail delivery system. If you do not agree with this process, please let us know as
described below. Please also see the paragraph immediately above that describes the
consequences of your electing not to receive delivery of the notices and disclosures
electronically from us.
