RE: 2008 CIP CONTRACT SA � AMENDMENT 1

Dear Mr. Owen,
CIVIL ENGINEERING
While conducting the survey for subject project, the outfall of the existing storm drain
proposed to be replaced by this project was unable to be located. It appears to be buried
under sediment and debris. No as -built drawings exist describing the location of the
existing storm drain line, therefore we are unsure of its horizontal alignment.
Additionally, the topographic condition of the area near the presumed outfall location_
requires additional survey to be performed in order to adequately complete the design.
This amendment proposes to conduct a SUE to discover the horizontal alignment of the
existing storm drain line, locate and uncover the outfall, and perform the additional
topographic survey in area downstream.
Attached is the proposal from the surveyor. The total fee includes the surveyor's fees
plus a 10% administrative markup for a total cost of $21750.00.
Should you require additional information please feel free to contact me at
817.253.5727 or claytonredinger(a�deotte.com.
Respectfully submitted,
Deotte, Inc.
