Harbor Economic Impact Model [Online Beta Test Version]

This page is an online implementation of the Harbor Economic Impact Model. I consider it to be in beta testing. You’re welcome to play around with it to test it out. I have not yet updated the underlying data, so it still uses data from 2004. If you run into errors, I’d appreciate hearing about them. You can find a contact form via my LLC’s consulting page. A User Manual is available for the latest version of the model, in case you need help: HEIM User Manual v1.9

Project Information

Determines borough assignment and local tax rates used in fiscal impact calculations. Community details can be reviewed and adjusted in the next step.

Adjust all vessel counts ±30% for sensitivity analysis. 0% = base case.

Community Information

These values are pre-loaded from the model database for the community you selected in Step 1. Edit any field to reflect more current or locally-known figures — changes apply only to this session and do not affect the stored community record.

Model Assumptions (advanced — optional)

These constants drive the underlying economic model and default to the values set by the site administrator. Adjust them here to test alternative assumptions for this session only — nothing here is saved as a new default.

Remainder is mapped to miscellaneous retail.
Multiplied against moorage revenue × mill rate. Not applied if the community is vessel-tax exempt.

Vessel Spending Rates

Annual spending per vessel (one boat operating for a full year), by length class and category. Values are pre-loaded from the model database. Edit any cell to reflect local conditions — changes apply only to this session and do not affect the stored defaults. Use the Reset to defaults button to restore original values for a vessel type.
