The objective of this training is to provide Local government floodplain managers and building officials in Washington with intermediate level training for making substantial improvement and substantial damage determinations.

After major disasters, numerous buildings in a community may be substantially damaged.  It is important for floodplain managers to have the knowledge and resources needed to process numerous substantial damage determinations during the rebuilding process. The core purpose of the substantial improvement/substantial damage rule is to bring nonconforming buildings up to current floodplain safety standards. It is important for floodplain managers to understand the accepted methodologies to do this. 

This course will discuss techniques for determining substantial improvement and substantial damage.  We will talk about regulatory requirements and managing substantial damage determinations in the post-disaster environment.

This training will take place on June 22 from 9-11 am and 1-3 pm on Zoom. 

Participants will have the option to log on 10 minutes early for a brief introduction to Zoom.
