CHAPTER 1 GENERAL:
The City of Eagle has adopted the current Edition of the Idaho Standards for Public
Works Construction (ISPWC). Prior to any public work development or construction, the
Owner or the Owner's representative shall review the above adopted standards. The
City has developed its own construction standards that supplement and supersede the
current edition of the ISPWC. These City standards include acceptable materials,
construction practices, and other specified requirements which may not be covered
under the ISPWC standards or contained in the City Code.
These standards have been made in conjunction with the current ISPWC. The intention
of these Construction Standards is not to conflict with the above stated standards, but
rather to supplement and specify construction methods, materials, sizes, and practices.
If a question arises between the two because of a conflict, then this matter shall be
brought to the attention of the City Engineer or the City Public Works Director.
