The expiration date for all Westport railroad parking permits is June 30, the Police Department's Railroad Parking Division announced Tuesday.

Renewal letters have been sent out to all permit holders.

For the first time, permit renewal letters have been sent by email to permit holders with a valid email address on file. If an email address is incorrect the permit holder will then receive a permit renewal letter by mail.

Current permit holders who have not received a renewal letter by the end of this week -- whether by email or by regular mail -- should contact the Railroad Parking Division.

Permits may be renewed in three ways: online, by mail, or in person at Police Department headquarters.

Online renewals are also charged a 3.5 percent conveyance fee. Online renewals and mail-in renewals will have the permits mailed to the address on record for that permit. Instructions for renewal are printed on the renewal letter.

The Railroad Parking Division does not have the capability to accept credit card payments by mail or at police headquarters. Credit cards may be used for only payment for online renewals.

Loss of or non-delivery of a renewal letter does not necessarily guarantee the permit holder the right to renew late; such cases are reviewed on an individual basis.

Parking permission for designated lots at the railroad stations is revoked if a permit is not renewed.
