Therefore, while the Concept 3 Alternative could result in greater emissions due to the more intense level of development, this could also result in a greater number of people accessing jobs, retail services, and entertainment destinations through walking, biking, or transit. On balance, this alternative is considered the same as the proposed TaD Strategy. The Concept 3 Alternative would result in more residential units, but a lesser amount of commercial/retail and office space. Overall, the Concept 3 Alternative would result in a greater amount of development, which would generate more vehicle trips and an increased level of traffic noise along major roadways. Other potential impacts, such as groundbourne vibration, and ambient noise would be present as a result of both the Concept 3 Alternative and the TOD Strategy. In addition, the significant and unavoidable impact related to exposure of exterior balconies to excessive noise levels would occur under this Alternative as well. The extent of this impact would likely be greater due to the 1,649 additional dwelling units that are envisioned at buildout. The Concept 3 Alternative would need to comply with the same mitigating General Plan policies as the proposed TOD Strategy. Therefore, the Concept 3 Alternative would be considered a substantial deterioration compared to the proposed TOD Strategy due to the expected increase in the amount of traffic noise and the likely exposure of more residents to excessive noise levels. Reasons for Not Selecting Alternative 3: This section qualitatively evaluates the potential The Concept 3 Alternative would meet all of the project objectives; however, as discussed below under item 3, the high number of residential units in relation to the reduced amount of office and retail USeS could adversely affect the project's ability to achieve the intended synergy between the various land uses. The Concept 3 Alternative has not been selected because the City determined that it included an excess of residential units in relation to commercial and retail uses. As with the proposed TOD Strategy, growth occurring under the Concept 3 Alternative would generate additional demand for water, sewer, and solid waste disposal. Since the Concept 3 Alternative would result in more growth in the TaD Strategy Area, the demand for utility services would be increased. As a result, the Concept 3 Alternative would result in an insubstantial deterioration in that the increased demand is more likely to trigger the need for new or expanded utility infrastructure, the construction of which could have significant environmental effects. Alternative 4: CMA Land Use Model fOT CMP Analysis Description of Alternative 4: In accordance with Alameda County Congestion Management Agency requirements, a Congestion Management Program (CMP) analysis was conducted for this project. This alternative would involve a mix of residential and job-generating land uses based on the development projections set forth in the most recent Alameda County Congestion Management Agency Countywide Travel Demand Model, which uses Association of Bay Area Government's (ABAG) Projections 2005 socio-economic forecasts. The CMP analysis focused on roadway links on Metropolitan Transportation System (MTS) and CMP highway segments and transit corridors, and did not extend to intersections. Consistent with the guidelines ofthe 2005 Congestion Management Program, the impacts of the TaD Strategy on the regional transportation system were assessed using the new ACCMA Countywide Travel Demand Model. Impacts/Feasibility of Alternative 4: The traffic forecasts were based on the most recent version of the Countywide Model, which uses Association of Bay Area Government's (ABAG) Projections 2005 socio-economic forecasts. The socio-economic data for the project area was added into the model for the 2015 and 2030 for all traffic analysis zones (TAZs) within the 34
