The best way of determining if you will be working in the city right-of-way is to find your property pins, as the width varies from street to street. Should anyone install any type of obstruction within the right-of-way without permission, it must be removed at the owner's expense.
Please read over the codes carefully to ensure all regulations are followed. Codes also display a fee schedule.
Please also note that any excavation within the right of way or on private property requires you to notify all of the surrounding utilities to mark out there infrastructure. Please see out Dig Safe / Utility Mark Out Notification page for more information.
