CEQA Requirements: CEQA Guidelines Section 15178 (e) states: When a lead agency determines that the cumulative impacts, growth inducing impacts and irreversible significant effects analysis in the Master EIR is inadequate for the subsequent project, the subsequent project is no longer eligible for the limited environmental review available under the Master Plan process and shall be reviewed according to Article 7 (commencing with Section 15080) of these guidelines. The lead agency shall tier the project specific EIR upon the Master EIR to the extent feasible under Section 15152. II.K. Finding: The cumulative impacts, growth inducing impacts and irreversible significant effects analyzed in the 1994 Master EIR still are applicable to the proposed subsequent project,Neighborhood F. The cumulative analysis in the 1994 Master EIR addressed cumulative impacts in various ways, depending on the topic. For some topics, specific projects within a 30-mile radius of the Mountain House site were addressed, and a list of 34 cumulative projects was prepared (see Table 6.1 of 1994 Master EIR). In addition,the cumulative analysis addressed in Chapter 6 of the 1994 Master EIR addressed the County's General Plan which addresses growth to 2010. This General Plan has been significantly amended since the 1994 Master EIR was certified, by deleting two new town projects,Riverbrook and New Jerusalem from the General Plan. While some of the cumulative projects identified in the 1994 Master EIR have been withdrawn or completed, other projects have been proposed since the original 1994 Master EIR was prepared. However, the overall cumulative analysis is still applicable, especially in terms of the project's relative contribution to the overall cumulative impacts identified. In addition,the 1994 Master EIR focused on the cumulative impacts of the overall buildout of the Mountain House New Community. The adopted Master Plan for Mountain House is consistent with the buildout projections evaluated in the 1994 Master EIR. No substantial changes have occurred in the cumulative traffic analysis which would require major revisions to the 1994 Master EIR. Cumulative traffic impacts have been recalculated for 2010 using the same accelerated build-out assumptions for Mountain House as the 1994 Master EIR, but with current regional housing, employment and traffic projections. The traffic study found that projected cumulative traffic conditions are essentially of similar or lower overall volumes than documented in the 1994 Master EIR resulting in generally similar or lower cumulative traffic volumes. Cumulative traffic impacts are also essentially similar or of lower impact than the 1994 Master EIR. The Initial Study traffic study found substantial decreases in freeway and highway traffic on 7 of the 9 segments evaluated and small increases on two segments. All freeway/highway segment levels of service remained the same or improved in comparison to the 1994 Master EIR traffic analysis. Of the 24 arterial road segments evaluated, 11 had similar levels of service, 11 had 'unproved levels of service, and two, Grant Line Extension and Tracy Boulevard north of Lammers Road,had decreased levels of service. The few road segments with lower levels of service can be mitigated with measures similar to that proposed in the MEIR. The proposed Grant Line Road 15
