Summary
Union City bans hedges, fences, and any other structure that blocks an existing sidewalk walkway or impedes pedestrian and vehicular sight lines within the public right-of-way.
No hedge, shrub or other planting whatever, fence or similar structure, shall be maintained across any existing walkway in a sidewalk area or shoulder. The intent of this restriction is to keep free a walkway for pedestrian or other lawful public travel without interference by or with vehicular travel. No encroachment of any nature will be permitted or maintained which impedes, obstructs or denies such pedestrian or other lawful travel within the limits of the right-of-way of a public street, or which impairs adequate sight distance for safe pedestrian or vehicular traffic. (Ord. 19-59 § 67, 1959)

Full Breakdown
Section 12.08.600 bars maintaining any hedge, shrub, fence or similar structure across an existing sidewalk walkway or shoulder, and more broadly prohibits any encroachment that impedes, obstructs or denies pedestrian or vehicular travel within the right-of-way, or that impairs sight distance. It sits within the same street-encroachment chapter as the City's permit system (§ 12.08.040), so even a permitted encroachment cannot be allowed to block the walkway itself. The City Engineer may order removal of a non-conforming obstruction under § 12.08.610.
Violations & Fines
Maintaining a hedge, fence, or other structure that blocks a sidewalk walkway or impairs traffic sight distance violates § 12.08.600, and the City Engineer can order it removed at the owner's expense.
