Agenda Date:09/27/2011 CITY Agenda Item: 5.2 OAKLEY A PLACIE.for FAMILIES in the HEART of the DEI:li\ MEMORANDUM Date: Tuesday, September 27, 2011 To: Bryan H. Montgomery, City Manager From: Jason Vogan, Public Works Director/City Engineer Subject: Capital Improvement Program Update The Public Works and Engineering capital improvement staff, in collaboration with various other City staff members; are currently working on numerous design and construction projects. Many of these projects are carryovers from the prior fiscal year, while a few are the result of the CIP update approved for this fiscal year. The following is a brief status report on the active projects: • Sierracrete Study- While not a standalone capital project, the Sierracrete study was to be the precursor to remediating the pavement issues that accompany this structurally flawed road base material. Although the County Health Department concluded several years ago that there was no health risk posed by the material, the poor performance of the pavement has clearly indicated that the material is inferior to traditional base rock. The study concluded that in general Sierracrete deteriorates roughly twice as fast as a traditional roadway. Structurally speaking, it would take more the twice the depth of asphalt over an equivalent depth of Sierracrete to provide the same support as a traditional roadway (i.e., 4.5" of asphalt over 6" of Sierracrete would be equivalent to 2" and asphalt over 6" of baserock). The study provides several remediation recommendations, the most expensive of which would be to entirely remove and replace all the Sierracrete material (roughly $13 per square foot). Since there are roughly 11 miles of Sierracrete streets in Oakley, full removal is probably not economically feasible unless outside sources can be identified. Since the bulk of the Sierracrete streets are in neighborhoods as opposed to collectors and arterials, staff believes that a more economically feasible approach will be to increase the surface treatment frequency for the Sierracrete Subject: CIP Update Date: September27, 2011 Pa e2of5 neighborhoods and to completely remove Sierracrete from the collectors and arterials. The logic behind staff's recommendation is that since neighborhood streets have less heavy vehicle weight and volume, their treatments are typically less expensive. Projects typically include limited digouts, crack sealing, and slurry sealing. Based on the report recommendations the City's surface treatment designer has developed a detail for the Sierracrete streets that includes a focused pavement removal in the areas that have surface cracking, a full depth removal in the failed areas, and a typical slurry seal for the remainder of the roadway. While the cost will be more expensive then our normal neighborhood treatment program the result should be a better functioning pavement. Staff is proposing that this approach be used in our next neighborhood treatment project (as described in the CIP 14 update, the next neighborhood to receive treatment will be the area north of Main and west of Miguel). As opposed to the neighborhood treatments, arterial and collector pavement rehab projects are much more involved and expensive. The extent of Sierracrete on these streets is pretty limited. As opposed to the increased maintenance frequency approach, staff believes these roadways will be better served by completely removing the Sierracrete material. The reconstructed roadway will perform better over time and the higher initial investment will result in a more efficient long term maintenance program. As discussed in the CIP 14 update, the first roadway to receive this treatment will be Empire Avenue between Main Street and Oakley Road. • Project 11, Main Street Downtown- This project will reconstruct and reconfigure existing Main Street in the downtown area from roughly Vintage Parkway to Norcross. The project will include a center landscaped median, one lane of traffic in each direction, and angled parking stalls on each side as well as enhanced . landscaping and street furniture. The design has been started and construction is anticipated to begin in the spring of 2012. • Project 12, Citywide Safety and Traffic Management Improvements- This annual project implements spot transportation safety improvements such as the Neighborhood Traffic Management Program (NTMP). Areas being studied include Silverspur Lane cut-through and speeds, Barndance Way volumes and speeds, and the Charles Way neighborhood volumes and speeds. The project also recently installed over a dozen radar speed signs that have been very well received by the community. • Project 13, Citywide Frontage Improvement Gap Closures- This annual project is used to fill in gaps in sidewalks throughout the City. The project on Empire Avenue at Oakley Road is well underway and is ahead of schedule. This project is also constructing medians in Empire Avenue and is incorporating a pavement rehabilitation project from roughly Holly Drive to Main Street. The pavement rehab Subject: CIP Update Date: September 27,2011 Pa e3of5 project was designed prior to the Sierracrete study, and the study confirms that there is a confined amount of Sierracrete in some of the areas that the County widened. Staff is working with the contractor to define the limits for removal and a change order will be prepared to remove the Sierracrete completely. It is likely that the change order amount will exceed Staffs approval authority so it will probably be presented to the City Council in October. Upcoming phases of gap closures will likely include Empire at Bedford, the last remaining gaps on Cypress, and Main Street projects following the relinquishment (such as the small gap between the mobile home park and Oil Can Henry). • Project 14, Citywide Pavement Management- This annual project is used to perform preventative maintenance on streets throughout the City. A neighborhood slurry seal project has been designed for the area north of Main and west of Miguel. The neighborhood includes Sierra crete so the project will be the start of that remediation effort. A separate project has been designed for Cypress Road between Empire and Rose. These repairs are more extensive then the slurry seal project, so the Cypress project will follow the bidding of the neighborhood project and may be phased depending on available budget. • Project 23, Main Street Medians, Bridgehead to Live Oak- This new project will install landscaped medians on Main Street from Bridgehead Road to as far east as funds will allow, (likely between Sandy Lane and Live Oak Avenue). The design agreement, which includes plans, specifications, and construction estimates for the entire stretch of Main Street from Bridgehead to Big Break, was approved at the first September meeting. • Project 77, Citywide Street Name Signs- This is the sixth installment of this project to replace all street name signs in Oakley with the current decorative standard.The project has replaced all arterial and collector street signs and will continue to transition into neighborhoods. • Project 91, O'Hara/Cypress Signalization- This project to widen and signalize the O'Hara and Cypress intersection is mostly complete, with only punchlist items remaining. • Project 92, Neroly Road Westerly Extension- This project to construct the westerly extension of Neroly Road from the new Neroly/Empire intersection is currently under construction. The project has been on hold while PG&E coordinates and schedules the utility connections, but the contractor should complete the project in October. • Project 96, O'Hara Widening, Cypress to Laurel- This project will widen O'Hara Avenue as a four lane divided arterial from Laurel Road north across the CCWD canal and in front of the Moura parcel. The project will also complete frontage improvements on the west side of O'Hara just north of Chianti. Design, Subject: CIP Update Date: September 27,2011 Pa e4of5 environmental, and property acquisition are underway. Staff is also coordinating access modifications and parking restrictions with the elementary school district. The project is planned to be constructed in the summer of 2012. • Project 100, Live Oak Storm Water Outfall- This project, to construct the detention basin outfall and three inlet structures for the existing basin west of Live Oak Avenue as well as a sewer extension in Live Oak was recently bid for the second time. The engineer's estimate for the project was less then $750,000 and bids again were in excess of $1.2 million. Staff is analyzing the bids and available funds to determine if there is a common issue driving the cost, and if the project may be able to be phased. • Project 105, Main Street Frontage Improvements- This project, to install frontage improvements and the poles for a future traffic signal on the south side of Main between the Public Storage center and the Raley's Shopping Center is 90% designed. The project will be constructed once Main Street has been relinquished, which should make the project cheaper and easier to implement. • Project 113, O'Hara Widening, Carpenter to Vintage- Design is nearing coQ]lletion, and PG&E is finalizing the utility relocation plans. An arborist has been retained to make recommendations on preserving the redwood tree. Construction will follow the utility relocation. • Project 116, Marsh Creek Restoration- Design of this project to widen Marsh Creek and restore habitat is nearly complete and resource agency permits have been applied for. Construction is planned for the spring of 2012. • Project 123, Holly Creek Park Phase II- Construction of this project to place irrigation and turf in the basin portion of the park is mostly complete and the plant establishment period is underway. The park is expected to be open for use at the beginning of November. • Project 124, Laurel Road Widening, O'Hara to Rose- This project, to widen the north side of Laurel from O'Hara to Rose Avenue, is currently under design. The project will realign the Laurel Ballfields driveway with Cloverbrook Avenue and will expand the parking lot at the park. The project is expected to go to construction next fall. • Project 125, LED Streetlight Replacement- This project will replace several hundred high pressure sodium streetlights with LED technology. All project agreements with PG&E have been approved, and PG&E reports that the materials have been ordered and the contractor has been selected. The lighting supplier indicates that the lights are in high demand and are being delivered as quickly as they can be manufactured. Subject: CIP Update Date: September 27, 2011 Pa e5of5 • Project 128, Live Oak and Oakley Road Pedestrian Pathway- This project which constructed a pedestrian pathway on the north side of Oakley Road and the east side of Live Oak Avenue to connect the Heather Park neighborhood to Orchard Park School is mostly complete. Only punchlist items remain. The project seems to have been well received by the community. • Project 130, Crockett Park All Access Playground- This project will replace the obsolete play equipment at Crockett Park with modern all abilities play equipment. Proposals have been obtained from three suppliers and the equipment will be ordered as soon as one has been selected. Delivery team and installation should take a month to six weeks. • Project 131, Oakley Downtown Revitalization -In conjunction with Project 11, two new restaurants will be constructed on Main Street in front of City Hall, along with a public plaza between the restaurants. The City Council has approved the design and the Disposition and Development Agreements required to proceed with the project, and the design work on the restaurants is well underway. Also, the current Oakley Plaza strip mall and the CentroMart buildings will receive new facades and the associated parking lot will be rehabilitated. The Ad-Hoc Committee has reviewed some preliminary designs and will present those ideas during a work session at the September 2ih City Council Meeting.
