NORFOLK, Va. (AP) - Norfolk officials are urging residents to take notice of proposed changes to federal flood insurance rate maps in the wake of Hurricane Matthew.

The Virginian-Pilot reports that the rate maps would require some landowners to buy coverage and put some properties in new risk areas.

The proposed changes would add more than 400 parcels to the highest risk category and would remove about 600 properties from zones requiring flood insurance on federally backed mortgages.

The Norfolk Planning Commission will hold a public hearing on the proposed changes Thursday afternoon. The Norfolk City Council is expected to vote on the proposed changes in December.
