3. Authorize the CAO to award the contract if the lowest responsible bid is within the budget
amount of$849,812.

DISCUSSION
The City's Pavement Management Plan(PMP)was adopted by the City Council on April 14, 1998.
The key elements of the PMP are the establishment of eight principal areas within the city, and a
maintenance plan in which each of these eight areas will receive maintenance over an eight-year
period. Streets located in the central downtown area are not part of this rotation because they
require maintenance more frequently. This project completes required major pavement work in
Area 3.
Earlier this year, Pavement Engineering,Inc., a private consulting firm specializing in pavement
design and deflection testing, was awarded a contract for engineering services. They performed
structural testing of selected City streets primarily located in pavement area 3. The streets tested
were those that had already been selected for rehabilitation based on the City's Pavement
Management Plan (PMP), which utilizes the computer program MicroPaver. Pavement
Engineering conducted the tests using the dynaflect method, a nondestructive testing method of
determining a street's structural integrity. As part of its contract with the city, Pavement
Engineering issued its findings in a report, "2000 Pavement Deflection Analysis for City of San
Luis Obispo Various Streets,"in which test results and design recommendations are presented.
Adjacent to one of the streets included in this plan,Rockview Place,is a City-owned piece of land
that has historically been subject to landslides. This property is currently being studied for a
permanent solution to the landslide problem. In the meantime, an interim solution, included in
these plans, is the installation of a shallow groundwater removal system,known as an underdrain,
adjacent to the street and at the base of the landslide area. The underdrain will reduce the amount
of subsurface water adjacent to the slide,thus strengthening the soil and reducing the likelihood of
further slides damaging the street until the more permanent solution is in place. The new

underdrain system will also provide a connection point for additional underdrains that may be
installed in the future.
Included with this project is the paving of the parking lot at the Laguna Lake Golf Course. The
paving of the golf course parking lot is a separate Capital Improvement Plan, approved for the
2000-01 budget. The transfer of funds from the Golf Course Parking Lot Project account into the
Pavement Management account will take place after July 1,2000.
CAO recommendation item #4 listed above is the transfer of $365,000 from the Pavement
Management account to the Santa Rosa/Monterey/CaliforniaWaterline project account. Monterey
Street and California Blvd are prime candidates for major overlay work. A waterline project,
however,is scheduled at these same locations later this year. The paving of Monterey from Santa
Rosa to California,and California from Monterey to Phillips will take place as part of the waterline
project, and the cost of the paving portion of that project ($365,000) will be paid for by the
Pavement Management Fund. The transfer of funds is to cover the expense of paving Monterey
Street and California Blvd.
