Walter, Public Works Director' Manuel Guzman, Engineer I SUBJECT: LOS OSOS VALLEY ROAD REHABILITATION SPECIFICATION NO. 90546 CAO RECOMMENDATION 1. Approve plans and specifications for the Los Osos Valley Road Rehabilitation Project Specification No. 90546. 2. Authorize staff to advertise for bids and authorize the CAO to award the contract if the lowest responsible bid is less than or equal. to the Engineer's Estimate of $1,429,000 ($1,366,000 General Fund, $47,000 Water System Improvements and $16,000 Collection System Improvements.) DISCUSSION Street Reconstruction The City's Pavement Maintenance Plan (PMP) was adopted by the City Council on April 14, 1998. One element of the PMP is the rehabilitation of Los Osos Valley Road. This particular project includes the resurfacing of Los Osos Valley Road from Highway 101 to the northern City limits. A new surface will prevent the street from deteriorating as well as provide an improved appearance. The particular surface treatment selected for Los Osos Valley Road in this upcoming project is based on field deflection testing of the pavement, and will include a combination of asphalt overlay and microsurfacing, a seal coat similar to slung seal. Water and sewer valve wells and manholes will be raised to meet to match the new finishing street surface. Pre-paving Work An important component of pavement maintenance and management is the coordination of work in the same area that will result in cutting of the pavement. I. ADA Compliance Prior to roadway improvements, the existing street intersection comers between Madonna Road and Highway 101 will be upgraded to meet current adopted standards for access. Some of the corners will only require the installation of the tactile "domes" while others will have to be reconstructed to meet required slopes. Los Osos Valley Road Rehabilitation Project Page 2 2. Storm Sewer Pipe Replacement This Project will replace an existing Corrugated Metal Pipe (CMP) that allows flowing water to travel under Los Osos Valley Road during winter storms. Last year staff observed street settlement in this area. Investigation of the pipeline revealed that the bottom of the pipe or flowline was completely dissolved. The missing flowline effectively eliminates the ability of the pipe to carry the street load and the result is street surface collapse. City staff made temporary repairs to this pipe. This project will replace this existing CMP pipeline with a Reinforced Concrete Pipe (RCP). I Catch Basins and Asphalt Concrete Berm Two new catch basins will also be installed as part of this project. One catch basin will replace an existing sidewalk underdrain near 12,100 Los Osos Valley Road, while the other catch basin will be installed across the street from 12250 Los Osos Valley Road. Both catch basins will be sized for current drainage requirements and will reduce the amount of rain water that ponds on the roadway. Because no drainage inlets currently exist near the two new catch basins, 470 feet of RCP pipe will also be installed, connecting the new inlets to the underground drainage system. The installation of 430 feet of Asphalt Concrete Berm will reduce the frequency in which water from an adjacent drainage ditch ponds in the eastbound lanes. 4. Curb and Gutter Removal and replacement of existing damaged curb and gutter in front of 12,424 Los Osos Valley Road is included with this roadway work as well. Trees that have since been removed lifted the existing curb and gutter resulting in poor street drainage. 5. The "Gap"property The one area in which construction will not be coordinated is the construction of improvements needed for 11980 Los Osos Valley Road, commonly referred to as the "Gap" property at Froom Ranch Road. The project is just beginning its EIR process and the reconstruction of Los Osos Valley Road would be significantly delayed if the work was to be coordinated. Construction Impact Mitigation Los Osos Valley Road is one of the City's busiest thoroughfares with a strong commercial area between the freeway and Madonna Road and a school near the westerly City limits. Paving work can not be completed without lane closures and congestion will occur during the work. Staff has approached the project recognizing these issues. To minimize the impact of construction, staff walked the commercial area and talked to the businesses about their busiest hours and delivery times. Allowable driveway closures have been specified for certain commercial properties to be no longer than one hour. Hours of work in the intersection of Madonna and Los Osos Valley roads have also been limited to avoid commute periods. The contractor's working hours in vicinity of the Laguna Middle School have been �s z .'I Los Osos Valley Road Rehabilitation Project Page 3 specified to avoid school start and finish times. The idea of doing the work at night was explored. It potentially will drive costs higher, lengthen the duration of the project and result in a poorer quality finished project. CONCURRENCES The Community Development Department has issued a Notice of Exemption for the construction. FISCAL IMPACT The Los Osos Valley Road Rehabilitation Project is identified in the approved 2007-09 Financial Plan, Appendix B. A total of$1,000,000 is currently available to fund the construction from the freeway to Madonna Road. Because of the proximity of the microsurfacing work planned for the stretch of Los Osos Valley Road between Madonna Road and the northwesterly City limits, that portion of this years surfacing project has been incorporated into this project. The current estimated cost for the general fund portion of the project is $1,513,200, with a combined funding of the originally scoped Los Osos Valley Road project from the freeway to Madonna and the funding for the surfacing project from Madonna to the City Limits. The funding for the surfacing west of Madonna Road will come from the 2005-07 Street Reconstruction and Resurfacing budget. Funding is currently available in the Water Distribution System Improvement and the Collection System Improvements accounts to fund utility work. The utility work consists of upgrading and restoring surface features, such as valve wells and manholes, to the new street grade.

TEM # W, � Subject: Proposed Work on Los Osos Valley Road andiWay Dear Mr. Haupt: The City Council received your letter to the Mayor dated June 21, 2007 regarding your concerns with the upcoming paving project on Los Osos Valley Rd (LOUR) and has asked the Public Works Department to respond. As you are already;aware, the paving project will be starting soon on Los Osos Valley Road (LOVR). This project is scheduled to start in mid.- October id-October and last for approximately two months. During that time the City will be paving LOVR from Highway 101 to the northwestern City limit. The City recognizes that this project cannot be completed without some inconvenience to the users of this street, and the residences and businesses in the vicinity of LOVR. City staff has walked the commercial area along LOVR explaining the project and asking for feedback from businesses regarding limiting working hours and expected lane and driveway.closures. As a result of this feedback, the Contractor will have restrictions placed on their work as part Of the contract. The working hours for this project have been limited to between 8:30 AM and 4:00 PM, Monday through Friday. No complete road closures will be allowed, including the Auto Park Way entrance to your dealership. Auto Park Way will have at a minimum one travel lane in both directions open for the duration of this project. This will allow customers to have access to your business during the hours you are open. Another important point to consider: even though the entire project will last about two months, the actual work in front of your business will be much shorter in duration, which we hope will lessen the inconvenience. No weekend work will be done on this project since LOVR has a larger traffic volume on weekends than weekdays, and night work will be considered only if necessary, because of the close proximity of homes and apartments. If you have any questions or additional concerns please contact Design Engineer Manuel Guzman at (805) 781-7423.
