6.F. - Page 2 of 4 in meeting its green infrastructure requirements set by the State. San Mateo County agreed to contribute $20,000 toward the cost of regrading the crosswalk across Bay Road at 10th Avenue to comply with Americans with Disbilities Act (ADA) requirements. In addition, the property owner/management group of 3700 Florence Avenue ("Marsh Manor") agreed to contribute $14,415 to cover the construction cost for curb ramp relocation and narrowing a driveway approach to allow for enhancements to the pedestrian crosswalk at Florence and 17th Avenue. City staff worked with the design consultant firm, CSG Consultants, Inc., to determine which of the projects realistically could be designed and built with current funding based on priority and cost of the improvements. Attachment A includes the scope and summary of the improvements for this project. While there was an extensive community process to develop the list of priority projects, staff also met with residents on site during the design phase to discuss the green infrastructure and intersection reconfiguration at Page Street and 5tn Avenue. These improvements will increase the safety of people walking and biking on the street and improve livability. The traffic calming measures will address safety and livability concerns such as excessive speeding and failure of drivers to yield to pedestrians. The project also includes green infrastructure improvements to treat the stormwater runoff. ANALYSIS The project generally consists of the following improvements: • Curb, gutter, sidewalk, driveway, and curb ramps • Concrete bulb -outs • Storm drain manholes and reinforced concrete pipes • Green infrastructure • Signing, striping, pavement marking, and speed humps • Rectangular rapid flash beacons (RRFB) The two bids received at the bid opening on May 24th, 2019 are summarized in the table below: Bidder Bid Amount 1 Grade Tech, Inc. $1,233,443.00 2 Sposeto Engineering, Inc. $1,647,188.00 Engineer's Estimate $1,100,000.00 to $1,200,000.00 The low bid of $1,233,443.00 submitted by Grade Tech, Inc. is 2.8 percent higher than the Engineer's estimate of $1,200,000.
