Road maintenance policies - Find a freedom of information request

I am getting in contact asking information regarding their road maintenance policies such as:

1) Has the council moved to a risk based approach when it comes to fixing potholes? If so, when did this happen? Ideally, month/year but if not possible just year?

2) What is your safety inspection regime in terms of checking roads? 

3) How do you classify road defects? Do you have a guide for this? 

4) Do you have any guidance on when a repair needs to be made? i.e.) how big does a defect need to get? 

5) What is your intervention/investigatory criteria specifically for potholes? Has this changed? Could you provide me with the previous criteria, if so?

I can confirm that the information requested is held by Lincolnshire County Council. I have detailed below the information that is being released to you.
