24th Street Bridge Over the Railroad Tracks (DPW 16-01)

The existing bridge over the UPPR tracks was constructed in 1959. The bridge was constructed with 2 lanes of traffic, and a narrow sidewalk on the south side with no bike lanes. It has been a long-time priority by the City Council to improve this bridge.

The City has a Highway Bridge Program (HBP) Grant, in the amount of $723,714, for final design. In September 2016, the City engaged the services of AECOM to perform the work (after a thorough Federal-Aid procurement process). A Notice to Proceed was issued in October 2016.

Current work is to gather field data to begin the design work. We need to do some borings in the UPRR right-of-way, to get soils data and perform construction surveying. We are in the process of procuring an encroachment permit from UPRR, which is a 6-8 month process.

Final design is anticipated to be completed within 18-24 months. The City will then apply to Caltrans for a Grant to construct the project.

Sherwood Sewer Replacement (DPW 16-21)

Due to aging infrastructure and increase frequency of high maintenance activity to keep the sewer system of Tract 67 (circa 1952), and Tract 172 (circa 1959) clear and functional, the City has decided to proceed with a sewer replacement project to restore integrity to the system and to significantly reduce the potential for sewer system overflows (SSOs), public health concerns and costly fines. The scope of the project generally consists of:

  • Replacement of approximately 5,000 linear feet of 6 inch diameter vitrified clay (VCP) gravity sewer pipe using trenchless construction methods, within the backyard easements and alleyways of the 124 lots fronting the following streets: Santa Fe Ave., Santa Cruz Ave., Santa Ysabel Ave., Santa Ynez Ave., San Carlos Dr., San Augustine Dr., San Fernando Dr., Via Ramona Dr., and San Rafael Dr.
  • Restoration of approximately 124 lateral connections to the new sewer lines.
  • Repair/replacement of approximately 20 sewer manholes and cleanouts.

13th Street Pedestrian Improvements from Park to Pine Street (DPW 16-23)

The City of Paso Robles has received a Grant to initiate the design work to improve and enhance pedestrian safety and amenities along the corridor.  The project is in the Preliminary Design stage.  Once the project is accepted for final design, then funding for the project will be allocated and will then move into the construction phase.

Spring Street - 10th to 16th (DPW 12-12F-3)

Planned Construction:

  • Conduits for future fiber optics and signal synchronization from 10th to 16th.
  • Upgrade sewer main across 14th Street.
  • Repair miscellaneous water valves, water services and fire hydrant repairs.
  • Fill in gaps of street trees (approximately 6-8).
  • Replace traffic loops with video camera detection at 12th and 13th Street traffic signals.
  • Improve drainage at 13th and 14th Street intersection
  • Remove and replace deteriorated asphalt (full width), from 10th to 16th.

Work began: April 2017
Completion: Late summer 2017

June 15, 2017
Contractor is gearing up for the last phase of work on the Spring Street - 10th to 16th repairs.

They are working in getting the concrete areas done so that they can begin the last phase - paving.  Attached are photos of the areas of concrete that have been completed.  The most noteworthy is the concrete cross-gutter at 13th Street. 

Starting on Sunday night, June 19th, they will begin to grind out the asphalt surface from 10th to 16th (3.5 inches). Final surface asphalt for the entire corridor will be placed the week of June 25th.

All work is planned for the evening hours to minimize impact to traffic.

June 6, 2017
As noted on the photos, the removal of old storm drains and installation of new are completed at 14th Street.  They are still installing some Drain Inlet structures but otherwise the storm drain system is just about done.

Starting on the evening of June 4th, the Contractor began excavating the road section at the intersection of 13th and 14th, and placing and compacting base.  The asphalt grindings were salvaged and stockpiled at the City Yard.  Street crews will place these grindings at Hanson Road.  First lift of asphalt for these intersections will be installed the evening of June 8th.

May 4, 2017 Update
Water Main construction at 13th and Spring is complete. See a few “action” of photos of the work.  The work was completed during the night hours.

The Contractor is now moving to the replacement/installation of conduits.  The signals at 12th and 13th have been operating on “recall” because the in-pavement detection system was removed during the excavation for  the waterlines.  This means the signal is working by “giving time” to all the movements instead of being efficient and only giving time when it detects vehicles are approaching.

The in-pavement detection system will be converted to video camera detection.  Once all the conduits and wiring are complete, then the signals will be operating using the video camera detection and should operate more efficiently.  With “video camera” detection in place, anytime excavation on the pavement is needed, the signals would continue to be efficient and not have to rely on the in-pavement detection system.

FYI, the signals at 1st, 4th, 6th, and 10th were converted to video camera last summer.  So with the completion of 12th and 13th signals this summer, the entire Spring Street corridor traffic signal system will now be a video camera detection.

April 24, 2017 Update

  • Upgrade of old sewer pipe across 14th at Spring Street is complete
  • Miscellaneous upgrade and repairs of old water services, valves, fire hydrant lines are complete
  • Work has moved to the replacement of old water pipes across 13th Street

Sherwood Repairs - Creston to Linne (DPW 12-12I)

May 1, 2017
Final design for the repair of Sherwood - Creston to Linne has began so that it can be in construction by 2018 per the adopted list of streets schedule using Supplemental Sales Tax. Last week, soils engineers were on-site to perform drilling of the existing roadway (see attached photos). The data from the borings will be used to establish the final street structure that will be needed for the road repairs. A few weeks ago, construction surveyors were also on-site to gather field data survey to be used for the final design as well.

Project will feature the following items:

  • Install a new traffic signal at Commerce.
  • Complete the missing curb, gutter, and sidewalk at the corner across from Food-4-Less.
  • Upgrade the old sewer pipes between Commerce and Linne.
  • Improve and resurface deteriorated asphalt.
  • Install additional street trees along the south side.
  • Install a landscaped raised median.
  • Install decorative streetlights.
  • Stripe and paint the bike lanes.

Construction schedule: Summer 2018

Vine Street - 32nd to Caballo (DPW 12-12J-1)

This is the dirt area behind the Georgia Brown School. The project is in the design stage, and has the following features:

  • Lowering of a shallow existing water main.
  • Grade and pave the dirt area with new asphalt.
  • Upgrade the curb ramps at 32nd and at Arlene.

Construction schedule: Summer 2018

May 5, 2017
The design work has begun with the field work to drill for soils data and perform infiltration test.
