Because of our recent work we can prepare this study cost-effectively using most of the information we already have. The following is our proposed scope of work. Scope of \V ork The traffic study described below will be prepared as ¡Ill addendum to the 1975 EIR to update existing conditions and cumulative project traffic generation. Tbe study will not contain specific EJR elements including pedestrian and bicycle: circulation, evaluation of alternatives, and a mitigation moIÚtoring program. T ",sk 1. Collect Data Data collection will include morning and afternoon peak period traffic counts at six key intersections, and field reconnaissance to observe traffil; conditions and ~Cific problems. We will obtain the most recent Caltrans freeway ramp counts (March 199 ) for the Marine and Redwood Shores Parkway interchanges with Highway 101 and adjust them to reflect conditions at the time of the intersection traffic counts. The five intersections are: -Marine PkwylBridge Pkwy -Twin Dolphin Pkwy/Sboreline Drive -Marine pkwyrrwin Dolphin Pkwy -Redwood Shores PkwylBrid~ Pkwy ·Redwood Shores Pkwyrrwin Dolphin Pkwy -Marine Pkwy/Orac1e Pkway est In addition to traffic counts, we will contact the City 8l'I d Redwood Shores Properties to update the list of projects on the Redwood Shores PeninSl:la and other nearby areas (WestpOrt, Centrum and Island Parle). We anticipate that sevl~ral changes have occurred since our previous study of tlUs area (February 1992) and will ne:d to update the project list to detennine cumulative traffic generation. Our previous study included 885,000 square feet of oftlce in the Electronic Arts site, but there may be other changes such as rezoning and projects which have changed size since our preparation of the Lido Neighborhood EIR. This taSk includes a review oftlle 1975 EIR and the 1987 Cr.ain Study. Task: 2. S valuate ExistinB Conditions We will perform morning and afternoon peak hour analyses of the study intersections and interchange ramps (does not include mainline ramp junctions) to establish existing conditions using a service level methodology specified by the Cit)'.
