3H-!{ Part 1 - Off-Site Traffic Impacts Task 1-1: Site Reconnaissance and Data Collection The physical characteristics of the site and the surrounding roadway network will be reviewed during a site visit to identify existing roadway cross-sections, intersection lane configurations, traffic control devices, surrounding land uses, and the locations of pedestrian, bicycle, and transit facilities. We have current AM and PM peak-hour intersection traffic volumes in our file~ for three of the key intersections. New peak-period manual turning movement counts will be conducted at the ten remaining intersections. Twenty-four hour machine counts and speed surveys will be conducted on Warren Street and on Allerton Street between Howland and Standish Streets, per the City's Request for Proposal. Task 1-2: Existing Conditions The existing operations of the key intersections will be evaluated with level of service calculations. Existing Conditions on the study segments of Warren and Allerton Streets will be described in terms of daily volumes and 85th percentile speeds. Task 1-3: Background Conditions Future traffic volumes from approved (but not yet constructed) developments to be provided by City Staff will be added to the existing volumes to obtain traffic volumes for Background Conditions. IntersectiQn level of service calculations will be performed to eval118;te Background Conditions. Task 1-4: Project Traffic Estimates . The amount of traffic added to the roadway system by the office building will be estimated by applying appropriate trip generation rates from the Institute of Transportation Engineers CITE), Trip . Generation (sixth edition) to the building's size expressed in 1,000s of square feet. A reduction in trip generation may be applied to reflect transit usage due to the site's proximity to the Redwood City CalTrain Station. The directions that the project trips will use to approach and depart the site will be estimated based on existing traffic patterns in the area and the relative locations of complementary uses, such as residential neighborhoods. . . The project's peak-hour traffic estimates will then be assigned to the adjacent roadways and key intersections. PIO308-5 . -.., . "'----'--""T-""
