Location of existing culverts and small structures Size Length Diameter Fill Depth Slope Condition Rating system Excellent – Good – Fair‐ Poor – Needs Replaced
Priority
Purpose of Inventory
To know the condition of our culverts To plan for future projects Added costs Doing it right the first time Make sure we have the pipe needed on hand or ordered Replace what is bad before we begin a street project Especially if it is a hard surface project To complete the project in a timely and cost effective mannerPipe Maintenance
Determining needs from timely inspection reports Reacting to the inspection reports Guidance in maintenance procedures and methods Repair vs replaceCONCRETE CULVERTS

Deterioration of the pipe Rusting through Seems or bands coming apart Concrete failure Common failures End sections tipping or falling off Erosion Undermining Collapsing Settling Sediment and debris causing reduced or no flowItems of Importance
Flared Ends Safety Ends Beveled for Trash Type of Pipe CMP or Concrete Round Arched BoxMethod To Be Used
Visual and hand written evaluation Use of a contractor ( Engineering Company) Visual and electronic submission of data GPS device with notes Juno device No method (common method in smaller cities) Replace after failure (also common) Planning for the futureThe JUNO System
Hand held electronic device (around $850 State Contract) It is a full service device GPS location of center and both ends Stores pipe dimensions Drop down box for condition Has condition box that can be checked Capable of taking and attaching pictures Miscellaneous screen for making notes Can also be a good tool for street signs ect.Hand Written Method
Pros: Very effective Easy to use Understandable Easy to Learn Cons: Need to attach photos Time consuming Another file of cumbersome papersCULVERT INSPECTION CHECKLIST

Conclusion
Must be used in some form to make cost effective and responsible decisions A way to communicate with your council as to your needs looking forward A means to track repairs and maintenance as completed As a budgeting tool To prevent damage in the future Both property and infrastructureSign Inventory – Paper Method
What must we know
Sign inventory number
Location (GPS Location)
Sign type (R1‐1 R1‐2 W11‐19 W2‐4 MUTCD#)
Size of sign (30X30 36X36 12X36)
Post type (round‐ square – U channel – Metal – Wood size of post 2x2 4x4 4x6 telspar) Height Lateral offset
continued
Sheeting (engineer grade – diamond grade ect.) Reflectivity (night time or reflectometer) Sign facing direction ( east west north south) Condition of sign ( sign blank – sheeting – post)
Needs (repaired or replaced or OK)
Is it the proper sign
