OutcomesforSMSRA
A CREAT generated report served as tool to communicate results to
stakeholders and the community.
Software assisted SMRSA in a regional planning effort by assisting
the Authority in prioritizing their options.
The pump station mobile enclosure strategy was the first ever
recipient of the Federal Emergency Management Agency (FEMA)’s
“Least Cost Alternative Project” award.
