The green bags at the base of the young trees on Montrose Boulevard are the newest part of the street. They're called Gator bags. Crews fill them every day unless enough rain has fallen, and they release water slowly to the roots. Next to them, watering tubes go down toward the root zone so workers can put water where it's needed and check how wet the soil is. Community Impact reported last week that more than 30 trees on the boulevard were replaced after many died or struggled in the summer heat.

That small detail says a lot about where Montrose's street work stands this fall. The heavy construction on the boulevard is basically over. What's left is slower work: keeping the trees alive, finishing the punch list, and waiting for the City to sign off on plans. That's true of the boulevard and of the projects lined up after it.

What half a mile of new street gives you on foot

Segment 1 of the Montrose Boulevard Improvement Project runs about half a mile, from Allen Parkway to W. Clay Street. The Montrose TIRZ 27 project page lays out how the sidewalks change along the way:

The sidewalks get narrower where an old tree stood in the way, and that tells you what the designers cared about. The plan gave up sidewalk width to keep existing trees.

At the intersections, the design adds upgraded crossings and ramps with signals, no-right-turn-on-red signs, and high-visibility crosswalks. A HAWK signal, which stands for High-Intensity Activated Crosswalk, goes in at W. Clay Street near Wharton Elementary. Along the whole corridor, City-owned Davit double-luminaire streetlights light the sidewalks. The TIRZ says the streetlights are "progressing towards being turned on," so evening walks may not get the full effect yet.

The car lanes didn't change much. The boulevard still has four 12-foot lanes, two in each direction. The new pavement is 11-inch concrete designed to last at least 50 years, and the corridor has been upgraded to support METRO's BOOST 56 bus service. Planners expect daily traffic to grow from 24,022 vehicles to 29,021 by 2040, and they kept the lane count to handle it. Nearly all of the change on this street is for people walking under the trees and the new lights.

Why the trees had to be planted twice

The tree plan dated March 2025 calls for 112 trees: 13 live oaks and 99 Lanana cypress. The TIRZ says the cypress came out of community engagement. They're planted north of W. Dallas Street as a visual transition into Buffalo Bayou Park, and the live oaks are there to match the mature oaks being kept along the road.

Then the summer went badly for the young trees. In Community Impact's account of the Montrose Redevelopment Authority meeting, Michael Robinson, a principal and landscape architect with SWA Group, which designed the landscaping, said his firm's assessment found the trees had not been watered properly.

"It is unfortunate that the trees perished," Robinson said, as reported by Community Impact.

He pointed to two more problems. The project specifications call for planting between Oct. 1 and Feb. 28, which he called the ideal window, and trees planted later, as temperatures rise, have a harder time getting established. Watering also washed out the soil mounds built around each tree to hold water. When crews watered from trucks with hoses, the force of the water knocked the mounds down, so water couldn't pool and soak into the roots.

That's why the replacements went in this October, at the start of the planting window. The daily Gator bags and the watering tubes replace hose spray from a truck.

The maintenance period is the biggest change. Robinson said the project carries a four-year watering period, compared with the two years these projects typically require. The longer period was recommended because the corridor is so visible. The TIRZ says the contractor is replacing the affected trees under the project warranty at no cost to the TIRZ or the community, and that the stronger maintenance program comes at no cost to the TIRZ either. Community Impact noted that the original planting count, the total number of trees lost and the replacement cost weren't given at the meeting.

So the boulevard's look over the next few summers depends less on construction crews and more on how consistently those bags get filled.

The bridge at the north end

At Allen Parkway, the TIRZ and Downtown TIRZ 3 are installing a pedestrian bridge to connect Montrose to Buffalo Bayou Park. The Downtown Redevelopment Authority calls it the Montrose Pedestrian-Bicycle Bridge. On the other side is a well-used part of the park. According to Buffalo Bayou Partnership, Johnny Steele Dog Park sits on the south bank of the bayou just west of the Montrose Boulevard and Allen Parkway intersection, at 2929 Allen Parkway.

The latest word on Segment 1 is in the TIRZ's October 2026 progress report. It says the remaining punch-list items can now be handled because the bridge rail materials have arrived. It also lists ongoing landscape warranty work and tree replacement updates. The October 15 draft schedule lists "Final Completion" for the segment but gives no date. The project page also warns that single-lane closures may still be needed.

South of W. Clay, a different project

If you drive past W. Clay toward Westheimer and see crews, they aren't part of the TIRZ project. The TIRZ points out that City of Houston Public Works is doing separate work on that stretch: resurfacing, spot sidewalk and ADA repairs, and storm-sewer inlet upgrades. The TIRZ sends questions about it to 311. Both jobs go by "Montrose Boulevard," but they have different owners and different contacts.

The next walking projects are waiting on paperwork

In September, Community Impact reported that TIRZ officials expected the Montrose Safe Routes to School Connections project to start construction in early October, with Mandell Street to follow in late October or early November. The October progress report, written about a month later, shows both projects still at the approval stage:

• Safe Routes to School Connections: final City comments are being addressed, and a notice to proceed can be scheduled after plan approval.
• Mandell Street sidewalks: the City has routed the plans for signature, and a notice to proceed can be scheduled after plan approval.
• Cherryhurst sidewalks: the contractor is working through punch-list items, and retainage has not been released yet.

The draft schedule now has Safe Routes construction starting in October or November 2026 and lasting about a year, which puts completion around October or November 2027. The TIRZ lists the project's pieces as a mid-block crossing on Columbus Street for Wharton Dual Language Academy, crossing signals at Stanford and W. Gray and at Stanford and W. Dallas, and pedestrian crossing signage at W. Clay and Crocker.

When Mandell does start, the scope includes 5-foot sidewalks with ADA-compliant ramps, milling and overlay of the worn asphalt, restriping, new signage where needed, upgraded streetlights, and a protection plan for each tree along the route. The tree plan carries over the lesson from Montrose Boulevard.

West Alabama is the long one

The largest project in the queue is the West Alabama Street Reconstruction. It covers about 1.6 miles from Shepherd Drive to Spur 527, and the Upper Kirby and Midtown TIRZs are handling the segments on either side. According to the August 2026 open-house presentation, the scope includes full roadway reconstruction, six-foot sidewalks where feasible, safer crossings and signals, storm-sewer and utility work, street lighting, and tree protection and planting. Joshua Driscoll of Asakura Robinson is the project's landscape architect, and the plans include oak and cedar elm.

That presentation projected construction to begin in late 2026 or early 2027 and finish in early 2029, and noted that the timeline could change. Design is still underway. The 75% plans went to the City for review on October 2, and the October report lists a follow-up item to present the project goals again with a focus on tree preservation and planting. The money is also lined up. A preliminary official statement dated October 19, 2026 proposes $29.895 million in Series 2026 tax-increment contract-revenue bonds to help pay for West Alabama, with a bond resolution expected November 17 and delivery around December 18.

Where the updates show up first

The Montrose Redevelopment Authority posts its board books on montrosehtx.org. The monthly progress report in each one is the most direct record of what has moved: which projects have a notice to proceed, which are still in City review, and how the boulevard's tree replacements are going. The November meeting, along with the expected West Alabama bond resolution on November 17, is the next point where several of these projects could change status at once.

We follow these blocks the same way you do. If you're weighing how a project like Mandell or West Alabama could affect a home you own or are thinking about, New Heights Group is glad to walk the street with you and talk it through. Let's talk about your next move.
