inform you of the appropriate bond amount after review of the cost estimate. Please obtain
the appropriate subdivision improvement bond forms from the City — available on the City
website.
Inspection fees for this project will be calculated at 3.3% of the 100% City approved
estimate for all improvements.

pedestrian and utility easement is required. The approval of such shall be brought before City
Council. The first step is a Council Committee process and the second step is approval before

3. Add Notes: "Utility patches shall be combined and full width or half width overlay will be
required depending on the extent of disturbance. Where utility patches fall entirely within one

relating to fitting connection type (MJ, FL)
• All City standard details need to be referenced on plans (water meter, concrete blocking, etc.)
