Rehabilitation Project, Specification Number. 91511; and
2. Authorize staff to advertise for bids; and
3. Authorize the City Manager to award the construction contract including the Base Bid and
any Additive Alternatives if the lowest responsible bid is within the Publicly Disclosed
Funding Amount of $3,500,000.
DISCUSSION
Background
The City’s Pavement Maintenance Plan (Pavement Plan) was adopted by the City Council on
April 14, 1998. The Pavement Plan was subsequently updated in 2009 to provide additional
emphasis on arterial street maintenance. The key element of the Pavement Plan is the
establishment of a rotating and methodical approach to ensuring all areas of the City receive
regular preventative or corrective maintenance. Most recent practice is to perform maintenance
in two neighborhood Pavement Areas one year, then focus on critical arterial street work the
following year, alternating between neighborhood areas and arterials each year. The last arterial
streets to undergo pavement maintenance were Johnson Street and Osos Street in 2015. In
summer 2016, neighborhood Pavement Areas 1 and 8 were completed. Over the last several
pavement projects, cost savings have resulted from project bid prices that were lower than the
engineer’s estimate and project budget. These costs savings have been accrued with the
intention of applying those funds to the next arterial street maintenance and rehabilitation
project.
It should be noted that prior practice was to perform sealing in one of the eight neighborhood
pavement areas each year. This approach enabled the city to stay on schedule for neighborhood
streets, however, the more expensive and heavily used arterials were completed only as the city
obtained grants or other sources of funding. The approach described above, alternating between
neighborhood streets and arterials, enables the city to maintain both on a regular basis. One
challenge is that the cost of the maintaining the arterial corridors exceeds the annual funding for
street maintenance. Therefore, as described below, several creative funding sources are utilized
to maintain the LOVR/Madonna corridors.
The Madonna – LOVR Rehabilitation Project plans to use several different maintenance and
rehabilitation techniques to extend the life of the roadway. Most of the project area will use a
microsurfacing maintenance treatment to seal the pavement. Microsurfacing is a cost -effective
treatment that extends pavement life up to 8 years. A portion of Madonna Road from Oceanaire
Packet Pg 495

to LOVR is structurally deficient and is planned to be reconstructed by a technique called Full
Depth Reclamation (FDR). Full Depth Reclamation recycles existing pavement by grinding it up
and incorporating it into the existing base soil. This process increases the base soil’s strength and
will correct the structural deficiency. A benefit of Full Depth Reclamation is that it produces
significant cost savings and environmental benefits over the traditional method of removing and
replacing the paving. These cost savings are primarily due to reduced material transportation and
trucking needs. Less material is required to be both imported and exported from the project area.
This project includes microsurfacing, repairing failed pavement sections, FDR, replacement of
failed sections of curb and gutter, installation of three new ADA curb ramps and substantial
roadway striping changes to improvement safety for roadway bicycle transportation. Bicycle
transportation improvements include the installation of green bike lanes, installation of buffered
bike lanes as well as the narrowing of vehicle travel lanes that encourage slower vehicle speeds.
Completion of the Madonna – LOVR Rehabilitation Project will enable the City to make
progress towards the Council’s established goal to maintain at least 70% of streets in good
condition and have no less than 7% of the City’s streets in bad condition. This project also helps
implement multimodal improvements, a Major City Goal, due to bicycle improvements.
ENVIRONMENTAL REVIEW
This project is categorically exempt from environmental review pursuant to section 15301 of the
CEQA Guidelines (Existing Facilities) since it is a maintenance and replacement project. A
Notice of Exemption has been filed through the Community Development Department.
FISCAL IMPACT
The project is structured with a Base Bid and two Additive Alternatives to maximize the scope of
the rehabilitation project within the available funding. The strategy is to award the contract with
the Base Bid and as many of the Additive Alternatives as funding will allow, up to the Publicly
Disclosed Funding amount of $3,500,000 in compliance with Public Contract Code Section
20103.8C. The Base Bid portion includes Los Osos Valley Road and Madonna Road from Los
Osos Valley Road to just past Oceanaire Drive. The additive alternatives include additional
microsurfacing and pavement repairs along Madonna Road to the HWY 101 South On/Off
Ramps.
There is currently a balance of $1,756,758 in the Street Reconstruction and Resurfacing Master
Account (Specification Number 90346). Additional funding of $1,685,000 is proposed in the
2017-19 Financial Plan Capital Request to augment the Master Account and provide adequate
funding for the annual pavement project. If the budget is approved as proposed, the additional
funding will be available July 1, 2017, bringing the funding available balance in the Street
Reconstruction and Resurfacing Master Account to $3,441,758.
Additional funding to help complete this work is planned to be obtained from the Los Osos
Valley Road Interchange Project. This project is largely complete with some required
landscaping and creek mitigation work pending. Within the project budget is $689,800 that may
Packet Pg 496

be used to restore Los Osos Valley Road and Madonna Road. During the Los Osos Valley Road
Project increased vehicle travelled on both roadways during construction thereby decreasing
roadway life. The Los Osos Interchange Bond Funding will be used to mitigate impacts on
LOVR from the LOVR interchange project
Other sources of funding include Bicycle Facility Improvements Account ($151,892), Water
Distribution System Improvements Master Account ($2,087,210), and the Collections System
Improvement Master Account ($1,307,716), and Sidewalk Ramp Construction ($45,000). These
funding sources support striping improvements for bicycle safety, adjustment of water and sewer
facilities to the new pavement elevations, and installation of three sidewalk ramps on Madonna
Road.
This proposed project will not be awarded until after the start of the new fiscal year, July 1,
2017, when the 2017-19 Financial Plan is adopted by Council and new funding is made
available. If Council has funded the 2017-19 Street Reconstruction & Resurfacing request at the
time of contract award, a Budget Amendment Request will be generated to transfer the funds to
the project account for construction. If the funding has not been approved or if funding is
approved but not sufficient to support this project’s needs, staff will recommend rejection of
bids, re-scoping of project and re-advertisement for bids.
Staff is recommending this project be approved for advertising in advance of final budget
adoption to allow for award of the project, and project completion prior to the start of Cal Poly’s
Fall Quarter, in mid-September 2017. Roadway construction could cause additional traffic
congestion and public inconvenience if done during the school year. This approach worked well
in 2013 when the city completed the maintenance of California Blvd This project is 72% funded
through the one-half percent sales tax measure approved by the City’s residents.

While the construction estimate for the Madonna – LOVR Rehabilitation Project is estimated at
$3,200,000, staff is requesting authorization to award a contract up to $3,500,000 to complete
this work. Staff is expecting a cost savings due to the use of FDR soil stabilization, but the City
has no prior history using this method for street reconstruction and bid prices could vary.
Regardless, FDR soil stabilization is significantly less expensive than traditional street
reconstruction methods using all new materials.
Remaining Street Reconstruction and Resurfacing Master Account funding is planned to be used
to repair concrete streets located at Dana and Nipomo, Palm and Johnson, and Palm and Toro, as
well as numerous pothole repair needs due to recent rain events.
ALTERNATIVES
1. Deny Authorization to Advertise and direct staff to redesign the project within the available
existing budget.
2. Deny authorization to advertise. The City Council may choose not to authorize project
advertisement. This is not recommended since summer is the best time to pave and seal
streets.
