National Wetlands Inventory maps are based on the 7.5' (1:24,000 or 1:25,000-scale) USGS topographic quadrangles. They are $6.00 each and are reproduced from mylars onto Diazo blue-line paper. The ESI office requires 3-5 working days, from the date the order is received to complete reproduction of maps (large orders may require more time). RUSH service is available at double the cost. If NWI's are needed by a particular date, it should be brought to our attention for appropiate action.

Shipping and handling charges per order are as follows:

• Rolled = $6.00/tube
• Folded = $4.00/envelope
• Federal Express = Shipped with clients acct. No.

All orders will shipped via US Postal Service regular mail unless alternate arrangements are made.

Mylars are forwarded to ESIO as finalized. Occasionally, drafts are available. Contact ESIO for confirmation of coverage. Some areas may only be available as 1:62,500, 1:100,000 or 1:250,000 scale maps.

Indexes are available upon request.
