A new floodplain map should help douse concerns potential buyers may have about investing in property at the Port of Walla Walla's proposed Burbank Business Park.
The Port is in the process of replacing its floodplain map from 1983, which officials say is outdated, based on unscientific estimates and consequently could be detrimental to the development of the business park.
A firm hired by the Port to review the data has analyzed the area and determined that properties within the boundaries of the proposed development with an elevation of 349 feet and higher are on the outside of the floodplain. That includes most of the land, Port Executive Director Jim Kuntz said Thursday.
"This is a very promising map," he said perusing the preliminary outline.
The Port is spending $22,000 on the effort. Once the company working on the project completes the map -- including incorporating as-yet collected data on elevations of the Snake River bridge and a railroad bridge -- it will submit a request to change the floodplain boundaries to the Federal Emergency Management Agency for consideration.
