If you’re buying, selling or holding property near these intersections, the immediate news is funding approval and a separate streetscape contract award. The decisions don’t establish a construction start date or say that property values, taxes or assessments will change.
On September 15, 2026, the San Gabriel City Council accepted $17,400,000 in Metro Measure R funds through Memorandum of Understanding agreements, or MOUs, for four intersection projects. It also awarded the Las Tunas Drive streetscape contract.
The San Gabriel Sun (Hey SoCal) reported on the council’s approval of Measure R funds for the intersection projects on Valley Boulevard and Mission Drive.
This is general information, not legal or tax advice.
What did the council approve?
The council approved MOUs for four intersection projects and separately approved plans and awarded a construction contract for Las Tunas Drive streetscape work.
The Measure R intersection locations are Valley Boulevard at New Avenue, Del Mar Avenue and San Gabriel Boulevard, plus Mission Drive at Las Tunas Drive. The agenda describes their purpose as reducing congestion. The consent calendar passed by a 5-0 vote.
Under the arrangement described in the agenda, Metro would continue its pre-construction responsibilities after execution of the MOUs. The city and Metro would then execute a separate Measure R funding agreement covering the city’s reimbursable construction activities.
For a nearby owner, that distinction matters: accepting funds through the MOUs is a step in the process. A separate construction funding agreement is still part of the sequence described.
When could construction happen?
The city’s agenda gives no construction start date, and completion is tentatively anticipated by June 30, 2028.
The agenda says that estimate depends largely on how long the right-of-way acquisition phase of pre-construction takes. Treat it as a tentative completion estimate when discussing a purchase or sale. It doesn’t tell you when work will reach a particular driveway or frontage.
Future council agendas are a practical place to watch for the separate Measure R funding agreement and right-of-way items. The city’s Agenda Center provides access to those agendas.
Keep the timing question separate from the design question. An environmental document can describe proposed work without supplying a construction start date.
What would change at Valley Boulevard and Del Mar Avenue?
The Del Mar Avenue project describes lane reconfiguration, intersection corner improvements and removal of on-street parking.
The city adopted a Mitigated Negative Declaration for this project in 2022. Its description includes a new dedicated eastbound right-turn lane, auxiliary lanes on Valley Boulevard in both directions, longer dedicated left-turn lanes in both directions and synchronized traffic signals along the Valley Boulevard arterial.
The 2022 environmental study described removal of approximately 50 on-street parking spaces. It described a minimum of five lanes with curb parking and sidewalks, except at the intersection approaches, where there would be no parking.
If your property relies on curb parking, this is a specific detail to check against the proposed figures and current plans. The study’s parking count may change in final design. For separate related reading about street parking in a neighboring city, see the Alhambra parking permit guide.
Does the Del Mar project involve private property or access changes?
The 2022 environmental study described a partial acquisition from a commercial parcel at the southwest corner and listed no residential acquisitions.
The existing roadway is within city right-of-way. The southwest corner work would require approximately 860 square feet of partial right-of-way acquisition from that commercial parcel, plus a temporary construction easement of 1,630 square feet. Those are the acquisition details in the study; they don’t establish an acquisition affecting a nearby home.
The 2022 environmental study also described construction in two phases. Phase one would close the outside lanes of eastbound and westbound Valley Boulevard and southbound Del Mar Avenue during work hours; phase two would close the inside lanes of Valley Boulevard. Work hours would be on weekdays from 7 AM to 7 PM. It said continuous access would be provided at all times and no detour routes would be needed.
Those phasing details and hours may change in final design. Ask Public Works about your specific frontage before relying on them for a transaction.
Say a buyer is considering a home near Valley Boulevard and Del Mar Avenue and wants to understand driveway access during construction. The buyer would find that the 2022 environmental study described continuous access during the phased lane closures, but those details may change in final design. Before relying on that description for the purchase, the buyer could ask Public Works whether the home’s frontage falls within the work area and check the current plans. The study’s listed acquisition from a commercial parcel would not establish an acquisition affecting that home.
What is planned at the other intersections?
The verified descriptions identify work at San Gabriel Boulevard and Mission Drive, while no design description was found for New Avenue.
At Valley Boulevard and San Gabriel Boulevard, the CEQAnet Notice of Exemption describes lane reconfiguration along San Gabriel Boulevard and a new curb ramp at the northwest corner. The proposed improvements would remain within the existing right-of-way.
At Mission Drive and Las Tunas Drive, the Notice of Exemption describes widening southbound Mission Drive to provide congestion relief and improve operational efficiency and safety. Work includes a realigned sidewalk, new driveway and curb return, ADA compliant curb ramp, median modifications and traffic signal improvements.
Valley Boulevard at New Avenue is included in the MOUs. No state environmental (CEQA) filing for it turned up on CEQAnet, so its design isn’t described here. Don’t assume it has the same scope as the other intersections.
What does the Las Tunas streetscape contract cover?
The separate Las Tunas Drive contract covers streetscape and pedestrian enhancements, including a landscaped median and street furnishings.
The council awarded Construction Contract No. 25-58 for $680,600, plus a construction contingency of $68,060, for total authorization of up to $748,660.
The project description calls for a new landscaped median with a monument sign at the western city limit, along with 27 new street trees, 56 pedestrian and street lighting fixtures, 20 benches, 16 bicycle racks and 20 trash receptacles. The CEQA notice lists the location as Las Tunas Drive from the western city limit to the eastern city limit.
The notice identifies a Class 1 existing facilities categorical exemption. That corridor description doesn’t identify what will be installed outside any particular property. A frontage question still belongs with Public Works.
What should you check before buying or selling nearby?
Start with the property’s exact frontage, then compare the project documents with information from Public Works.
A useful check list is:
- Ask Public Works whether the frontage is inside a project’s work area or right-of-way plans.
- Search CEQAnet by SCH number: 2022060587 for Del Mar Avenue, 2022080562 for San Gabriel Boulevard, 2025110779 for Mission Drive and Las Tunas Drive, and 2026030401 for the Las Tunas streetscape.
- Read the project descriptions and figures, paying particular attention to curb parking if the property relies on it.
- Watch council agendas for the separate funding agreement and right-of-way items.

The short version
San Gabriel approved Measure R funding agreements for four intersections and awarded a separate Las Tunas streetscape contract, but the agenda gives no construction start date.
Completion is tentatively anticipated by June 30, 2028, depending largely on right-of-way acquisition. The Del Mar study describes parking removal and acquisition from a commercial parcel, with no residential acquisitions listed. The San Gabriel Boulevard improvements stay within existing right-of-way. New Avenue’s design isn’t described in the documents reviewed.
For your property, check the frontage and current plans before drawing conclusions about access, parking or timing.
