II. CUMULATIVE IMPACTS. The following impacts are considered cumulative, describing the incremental impact of the Project when added to other closely related past, present or reasonably probable future projects. The time period for analyzing most cumulative impacts was the year 2020. Once again, the letters and numbers assigned to each impact below correspond to the letters and numbers assigned to each impact in the EIR itself. As discussed below, implementation of the Project in conjunction with other City-approved projects would have significant, unavoidable cumulative impacts on Traffic and on Demand for Water. A. TRAFFIC, TRANSPORTATION, CIRCULATION AND PARKING. Impact D.9: The Project would increase vehicle delays at certain area intersections under cumulative (2020) conditions. (Significant). Impact D.9b: The Project would increase vehicle delays within an already unacceptable level of service by more than five seconds at the signalized intersection of Middlefield RoadlWoodside Road during the PM peak hour. Mitigation Measure D.9b: In the absence of readily-attainable capacity- enhancing measures to improve traffic conditions at the intersection of Middlefield RoadlWoodside Road, the Project sponsor would implement Mitigation Measure D.1 b (a more aggressive Transportation Demand Management [TDM] program) to reduce the travel demand at this intersection. In addition, the Project sponsor and the City of Redwood City shall work with Caltrans to add emergency vehicle signal pre-emption to the traffic signal control at this signalized intersection. The Project sponsor would be fully responsible for the enhanced TDM program, and would pay its fair share of the cost of the emergency signal pre-emption. Finding D.9b: For this intersection to operate at an acceptable level during the PM peak hour under Cumulative Plus Project Conditions, the dedicated eastbound and westbound right-turn lanes would need to be converted to a shared through/right-turn lane in each direction and add a receiving lane in each direction (essentially, the lane configurations if Woodside Road was widened to three lanes in each direction). In addition, a second eastbound left- turn lane would need to be constructed. These identified improvements include widening Woodside Road, which the City of Redwood City has identified as undesirable because of Caltrans design requirements. Therefore, to reduce impacts, it is recommended that the Project sponsor intensify their TDM program to reduce peak-hour vehicle trips 5 U:\ProjectslAbbott Labs\Planning Commission - EIR and Entitiements\Statement of Overriding ConsiderationslAbbott - Statement of Overriding Considertions.doc
