RE:	Project No. PW1210 – 2012 Overlay Program Phase 2 – City Bid No. B1232 May 15, 2012 Consent Agenda Item – Set Bid Date of May 29, 2012

Please include the following item on the City Commission consent agenda for consideration at the May 15, 2012 meeting:

Project Description.  This curb and gutter and milling and overlay project includes City residential, collector, and arterial streets (see attached location map).  The street curb and gutter and mill and overlay sections to be worked on are determined to be in generally fair to poor condition and have deteriorated beyond the point at which cost-effective preventative maintenance techniques can be performed.  An effective curb and gutter and milling and overlay program will reestablish desired drainage, structural, and ridability characteristics to a street and reduces other long-term maintenance and rehabilitation costs.

Project History.  The City’s annual pavement maintenance program was reviewed and approved by the City Commission on December 20, 2011.  Of the various program projects, the 2012 Microsurfacing Program was awarded on February 28, 2012, the 2012 Concrete Rehabilitation Program was awarded on April 17, 2012, the 2012 Overlay Program Phase 1 was awarded on April 24, 2012, the KLINK Overlay & Geometric Improvements work on 6^th St from Iowa St to Monterey Way was awarded on May 1, 2012, the 2012 Crack Seal Program (to be performed by City internal crews), and the 2012 CIP Reconstruction of Wakarusa Dr from Research Park Way to Oread West Dr are also planned for this construction season as presented at the December 20, 2011 City Commission Meeting.

Project Details.  The project includes the removal and replacement of curb and gutter sections, concrete intersection apron/valley gutter improvements, milling of existing pavement, patching of deteriorated areas, and the placement of a 2-inch asphalt overlay to restore structural capacity, skid resistance, proper drainage, and ride quality to the existing City streets.  Staff has reviewed the project with the “Complete Streets” policy and has incorporated elements that are fiscally and financially appropriate.  Elements planned for inclusion are:  ADA concrete access ramps and improved safety from pavement rehabilitation.

Project Funding.  The pavement maintenance program is funded from several sources including the general fund, gas tax funds, sales tax and sales tax reserve, and capital improvement reserve accounts.  Funding for the program was approved in August, 2011 and adopted in the 2012 City Budget.  This project was included in the 2012 Pavement Maintenance Program for overlay and curb rehabilitation to be paid from infrastructure sales tax funds. The contract includes an asphalt index which may require change order(s) based on the increases/decreases in asphalt oil pricing.

Action Request.  Set Bid Date of May 29, 2012 for the 2012 Overlay Program Phase 2 - Project No. PW1210.
