Honorable Mayor and Council Members
City of Ames
Ames, Iowa 50010
Ladies and Gentlemen:
I hereby certify that the utilities and asphalt base paving required as a condition for
approval of the final plat of Northridge Heights, 10th Addition have been completed in
an acceptable manner by Halbrook and Manatt's, Inc. The above mentioned
improvements have been inspected by the Public Works Engineering Division of the
City of Ames, Iowa, and found to meet City specifications and standards.
As a result of this certification, it is recommended that the financial security for public
improvements on file with the City for this subdivision be reduced to $73,350. The
remaining work that covers this financial security is street surface paving and the
Construction Site Erosion and Sediment Control Bond.
Sincerely,
John Joiner, P.E.
Public Works Director
City of Ames
