Are these charges criminal? "failure to give information after striking property"and "failure to reduce speed to avoid accident?

I hit a property while learning driving and left the place when owner didnt respond. Police found me within minutes and after i admitted, charged me with " failure to give information after striking property" and " failure to reduce speed to avoid accident". No fingerprinting and I have clean record. The officer said there is no criminal charges filed. does it affect my records? I need to appear in court. Do I need a lawyer? Is there any chances of these cases being dropped? If convicted, how long would it take to appear in my record? Please help.
