California Vehicle Code's latest requirements. When determining the speed limits, the consultant must also review the latest methodologies and include information summarizing how these new requirements have changed since the prior study. If any reduction from the 85% percentile speed is recommended, these shall be fully documented and follow the procedures required by the State of California in setting speed limits. 4. Prepare a Summary of Recommendations in chart form to include the street name, street segment, existing speed limit, recommended speed limit, 851 percentile speed, mean speed, 10 mph pace range, percent of vehicles in pace, date of survey, and reason for speed limit change from the 85th percentile (sample attached). The Summary of Recommendations shall include all street segments studied, unless otherwise specified by City staff. 5. Prepare a report which includes the following: a) A certification suitable for submittal to the municipal court system, b) Radar speed survey operational procedures, c) A description of the purpose and methodology of speed zone establishment, d) A description of the statistical analysis factors, e) A description of the field data used in analyzing the related roadway characteristics, f) Accident history for the street segments, g) Results and recommendations, and h) The Summary of Recommendations in chart form. 6. Consultant shall prepares sketches for sign changes. This task is based on an estimated number of 90 sign -posting locations that may require changes. Once all recommendations are confirmed by the City, this task may or may not be required by the City. In the fee proposal, please list the unit price to identify each sign location at a specific distance from the nearest curb extension. These changes will indicate if the sign is new, a replacement, and/or removal and if a new sign (only) or a new sign and post will be required. City staff would then use such sketches to write-up each work order for sign change. Sketches shall be done in a manner acceptable to the City and using the City's formats. Sketches shall be done by attaching electronic aerials photos into Microstation files and showing the sign post changes from the nearest curb return extension. Task No. 6 needs to be listed in Fee Proposal as a Separate Item with a price per unit cost listed for 90 locations. The City reserves the right to issue or not issue this Task or a portion of it. As part of the report preparation the selected consultant will do up to 5 presentations or public meetings to report out the study findings and recommendations. All procedures and speed limit recommendations shall be per the latest requirements in California Manual on Uniform Traffic Control Devices plus the latest law in the most current version of the California Vehicle Code.
