City staff outline proposed First Street closure for Alterra construction; detours planned Jan. 2026

City traffic engineering staff presented a proposed temporary closure of First Street between Old Town Front Street and Pujol Street to facilitate construction of sewer, water, storm drain and other street improvements required by the Alterra development.

Traffic engineer Vic Minicelli said the closure is required for worker and public safety during construction and that the developer anticipates the work beginning Jan. 5, 2026 and lasting about 30 days. Staff said the closure will include portable message signs and directional detours: northbound traffic on Pujol would be directed to Main Street then to Old Town Front Street; southbound drivers would be routed to Main Street before reaching First Street to avoid u‑turns and confusion. Similar detour guidance was described for Old Town Front Street and Santiago Road.

Minicelli and staff said they recognize the closure will affect Old Town traffic and that the timing in January may have lower visitor impacts. The committee received the informational presentation; staff said the matter will go to City Council this coming week for approval of the proposed closure.

— Ending: If council approves the closure, staff will implement detours, signage and public notifications prior to the January work window.
