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 works 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 and the City Water Superintendent.
