|Sanitary Sewer Replacement and Repair 2017 ($1.16M)
Throughout the year, routine and specific Closed Circuit TV (CCTV) inspections of the sanitary sewer system are performed. The inspection data is rated and logged into a database. Locations where critical defects and distresses are found are listed for development into point repairs, segment replacements or internal liner rehabilitation applications.
A number of sanitary sewer lines are located on private property and not always within recorded easements. Access limitations will be considered when determining the appropriate construction method to complete the work.This project will develop critically listed defects and distresses into optimal repair schemes, design, bid and construct repairs to the existing sanitary sewer collection system. The database will be updated on completion of the construction work.
Construction began in winter 2018.
This project is funded by Water Pollution Control Plant Enterprise funds.
Annual Street Overlay/Rehabilitation 2016-17 Phase I ($3.048M)
Engineering and Transportation staff rate and track the pavement condition, which is called the Pavement Condition Index (PCI), of every street in San Leandro. Streets in poor condition, with a PCI of 25 and above, can be repaired by milling or grinding off the top layer of pavement and installing three to four inches of new pavement. A mill and fill or overlay project such as this is more expensive than a cape seal but cheaper than replacement of the street section.
Streets that have reached the end of their useful life must be replaced. Cement is typically mixed into the soils below the road, after which a new pavement section is installed. This is the most expensive type of street rehabilitation work that we perform. Without this project, the average condition of the City's streets will decline. Streets that can be maintained at a moderate cost now will degrade to the point that more expensive repair is needed. Curb ramps along these streets segments will be upgraded to meet current Americans with Disabilities Act standards in advance of the planned paving activities. For a map and list of streets scheduled for rehabilitation during this project, click Annual Overlay/Rehabilitation 16-17 List of Streets.
For this year’s project, construction is currently underway to complete preventative maintenance paving improvements on selected streets throughout the City.
A striping plan for the intersection of San Leandro Blvd. and Best Ave. (shown in the above drawing) is an interim solution to calm traffic and provide orderly turning movements at the intersection. After implementation of this interim improvement plan, the Engineering & Transportation Department will continue to explore more efficient and safe mitigation plans for this location.
This project was made possible with General Funds, SB 1 Gas Tax, a CalRecycle grant, Measure B and Measure BB funds. Measure B and Measure BB funds are administered by the Alameda County Transportation Commission (Alameda CTC).
Bancroft/Sybil Signal Improvements ($600k)
At the intersection of Bancroft Avenue and Sybil Avenue, this project will add protected left-turn phases (left turn arrows) for three of the four intersection approaches with dedicated left-turn lanes. The traffic signal hardware will be replaced with new updated equipment. Curb ramps adjacent to the work will be upgraded to meet current Americans with Disabilities Act (ADA) compliance. The improvements will improve the overall traffic safety and traffic efficiency of the intersection.
This project will be constructed in early 2018.
Funding for this project is provided through the Highway Safety Improvement Program (HSIP) administered by California Department of Transportation (Caltrans).
