San Marcos / Santa Rita Avenue Roadway Improvements

In July 2016, San Francisco Public Works began roadway improvements on San Marcos and Santa Rita avenues that will include sewer replacement, stairway repair, concrete work on curbs, and sidewalk and driveway replacement. All sewers have been visually inspected via video camera and evaluated by San Francisco’s Public Utility Commission. An evaluation and condition assessment of the sewers under this project were completed and identified for full segment replacement. During detailed design, we explored trenchless technologies.  Under this project and where appropriate, two sewer location segments are designed for trenchless rehabilitation. The remaining locations are designed for open cut replacement.

Project Updates - November 2016 

4 trees to be removed opposite 57-65 and 60-64 Santa Rita Avenue

The project team has been meeting on site since mid-October to assess the potential tree root conflicts in the median opposite 57 to 65 and 60 to 64 Santa Rita Avenue in Forest Hill, where four large Monterey pine trees are located. The sewer location in the roadway is on the uphill side of Santa Rita Avenue and has been marked in white hash marks. With a 5' wide excavation for the sewer trench, and repairs to the curb, gutter and roadway that would follow, the Urban Forester for Public Works believes that impacting these roots will destabilize the trees.  The tree closest to the intersection of Mesa Ave. has large roots on the downhill side of the roadway that will also need to be pruned/removed. We will post the courtesy removal notices on the trees and nearby utility poles on Thursday, December 1, 2016.

The tree contractor is currently arranging for removal of these trees, following the process outlined in the communication plan which is contained within the resulting tree removal hearing decision, Order No. 185316. 

Tree Removal opposite 75 Santa Rita Ave.
The grade of the roadway at this particular location will need to be reduced to a depth that will require the removal of the entire 12" diameter root that has been located below the roadway. The Urban Forester for Public Works evaluated the proximity of this root to the closest tree (opposite 75 Santa Rita Ave), and believes that removing this root would cause this tree to become unstable and fall over. Alternative construction methods have been considered and would not adequately address this particular conflict.

The subject tree is not in great condition. Half of the tree was removed years ago and there is very little that remains of the canopy. For this reason, and to ensure public safety, the Urban Forester and project team is recommending that the tree be removed.  

The tree contractor is currently arranging for the emergency removal of this tree, following the process outlined in the communication plan which is contained within the resulting tree removal hearing decision, Order No. 185316.

 

September 2016

Roadway paving will continue on the odd side of San Marcos Ave. (301-201) through the week of September 12, 2016. 

Sewer work will begin on the even side of San Marcos Ave. (150-318) the week of Septemeber 19, 2016. Sewer work is anticipated to contunue for about 2 months. "No Parking / Tow Away" signs will be posted 72 hours in advance of work starting and will project work hours and parking restrictions.  

Tree Hearing Presentation (Director's Decision, DPW Order 185316, posted 9/21/16) new
The proximity of sewer replacement work to the tree trunks, tree size and median wall, may result in the need to remove trees. Public Works received letters protesting the proposed removal of trees from the median in Forest Hill. A tree hearing was held on Monday, August 22. 2016 to consider:

Removal with replacement of (20) twenty median street trees adjacent to 50-99 Santa Rita Avenue and 150-300 San Marcos Avenue. Public Works is committed to preserve as many trees as possible.  View the Director's Decision (DPW Order 185316) here. You may send comments or question here.
