Hi everyone, it's important to take an active part in the quality of spatial data. Firstly, regarding the acreage computations in SHOREZONE_IWWH see this note from Don Katnik:
People are sometimes confused when the acreage field does equal the value you get from Shape.Area because they don’t realize that the acreage doesn’t include the 250 ft upland zone or, for Shoreland Zoning, forested wetland acres. It’s in the attribute metadata.
From the metadata
for Shorezone_Iwwh:
Attribute Label:
SZ_WtlndAc
Attribute
Definition: Wetland acreage based on shoreland zoning definition
(does not include forested wetlands or upland zone)

Forward this from
the metadata for Shorezone_Iwwh:
Attribute Label:
SZ_WtlndAc
Attribute
Definition: Wetland acreage based on shoreland zoning definition
(does not include forested wetlands or upland zone)

Can I forward this back
to the geolibrary list (where everybody now thinks the acreage field is
wrong)? Or can you?

You need to use
shorezone_iwwh, not iwwh.
The files are
different.
Also, you need to
troubleshoot the shorezone_iwwh before you publish...don’t just drop it into
your Shoreland zoning map without checking the acreage field,
etc.
