3.0 SUMMARY OF IMPACTS AND MITIGATION MEASURES
INTRODUCTION
This chapter provides an overview of the Del Rio Hills Planned Unit Development (DRHPUD) project and its potential impacts. This chapter also provides a brief discussion of potentially viable development alternatives to the DRHPUD project. A detailed discussion of these alternatives can be found in Chapter 5 of this EIR. Table 3-1, at the end of this chapter, provides a summary of the environmental effects of the DRHPUD project identified in each technical issue section of Chapter 4. The table consists of the environmental impacts, the significance of the impacts prior to mitigation, the proposed mitigation measures, and the significance of the impacts after mitigation measures are implemented.
PROJECT UNDER REVIEW
The DRHPUD consists of approximately 505 acres of land located west of downtown Rio Vista, and south of SR 12. The project area is bounded to the west by Amerada Hess Road, to the south by unincorporated Solano County. The surrounding area is typified by rolling hills and agricultural activities, surrounded by rural residential uses. The DRHPUD would allow for a mix of residential neighborhoods, a SR commercial center, a proposed K-6 school, neighborhood parks, public facilities, recreation areas, and an extensive open space and trail network. The project would be developed over three phases, the first phase of which could begin as early as 2009.
POTENTIAL AREAS OF CONCERN
Comments received in response to the NOP and at the Scoping Meeting included the following:
Flood risk and drainage issues
Safety issues related to gas wells and gas pipelines
Traffic and circulation impacts along SR-12 and existing City roadways during construction and operation
Air quality impacts related to project construction and project generated vehicle operation
Hazard impacts related to former on-site agricultural production
Land use compatibility
Project and mitigation funding mechanisms
Visual quality of the proposed project
Sewer and water infrastructure
Safe and accessible pedestrian pathways to and from the project site
Soil erosion
Availability of adequate public service facilities

ALTERNATIVES TO THE PROPOSED PROJECT
The EIR analyzes the following alternatives to the proposed project:
No Project/ No Build Alternative: The No Project/No Build Alternative assumes that the proposed project would not be developed and agricultural development would continue to occur on the DRHPUD site. This alternative assumes the existing residence and outbuildings would remain and the rest of the site would not be altered relative to existing conditions.
No Project/ General Plan Buildout Alternative: The No Project General Plan Buildout Alternative assumes that the DRHPUD site would be developed consistent with the existing land use designations and zoning as identified in the current General Plan. The DRHPUD site would be developed using the midpoint of the allowable residential densities under this alternative.
General Plan Minimum Density Alternative: The General Plan Minimum Density Alternative assumes that the DRHPUD site would be developed consistent with the existing land use designations and zoning as identified in the current General Plan, using the lowest allowable residential and commercial densities.
Detailed descriptions and analysis of potential impacts of these alternatives are presented in Chapter 5.
SUMMARY OF IMPACTS
Table 3-1 provides a complete list of all impacts and mitigation measures for the topics evaluated in this EIR. For each impact, the table presents the significance of the impact before mitigation, applicable mitigation measures, and the level of significance of the impact after implementation of the mitigation measures.
Effects Found to be Less Than Significant
A number of project impacts identified in the EIR were found to have no impact or a less-than-significant impact, requiring no mitigation. These impacts are found in Chapter 4, Environmental Analysis, and are summarized in this Chapter in Table 3-1, Summary of Impacts and Mitigation Measures.
Significant Impacts
Pursuant to CEQA Guidelines Section 15382, a significant effect on the environment is defined as a substantially or potentially substantial adverse change in any of the physical conditions within the area affected by the project, including, land, air, water, minerals, flora, fauna, ambient noise, and objects of historic or aesthetic significant (CEQA Guidelines Section 15382). Implementation of the proposed project would result in significant impacts to some of these resources, which are fully analyzed in Chapter 4, Environmental Analysis, and are summarized in this Chapter in Table 3-1, Summary of Impacts and Mitigation Measures.
This EIR discusses mitigation measures that could be implemented by the City and/or the project applicant to reduce potential adverse impacts to a level that is considered less than significant. Such mitigation measures are noted in Chapter 4 of the EIR. A summary of these mitigation measures can be found in Table 3-1. The mitigation measures presented in this EIR form the basis of the Mitigation Monitoring Program, which is included in the Final EIR document.

Significant and Unavoidable Impacts
However, even with the application of feasible mitigation measures, some impacts could not be reduced to less-than-significant levels. The significant and unavoidable impacts that were identified for both project-level and cumulative impacts in Chapter 4, Environmental Analysis, and are summarized in this Chapter in Table 3-1, Summary of Impacts and Mitigation Measures.
SUMMARY TABLE
Table 3-1 (Summary of Impacts and Mitigation Measures), has been organized to correspond with the environmental issues discussed in Chapter 4. The summary table is arranged in four columns:
1. Environmental impacts (“Impact”).
2. Level of significance without mitigation (“Significance”).
3. Mitigation measures (“Mitigation Measure”).
4. The level of significance after implementation of mitigation measures (“Residual Significance”).
If an impact is determined to be significant or potentially significant, mitigation measures are identified, where appropriate and feasible. More than one mitigation measure may be required to reduce the impact to a less-than-significant level. This EIR assumes that all applicable plans, policies, and regulations would be implemented, including, but not necessarily limited to, City General Plan Policies, laws, City Ordinances, and requirements or recommendations of the City of Rio Vista. Applicable plans, policies, and regulations are identified and described in the Regulatory Setting of each issue area and within the relevant impact analysis. A description of the organization of the environmental analysis, as well as key foundational assumptions regarding the approach to the analysis, is provided in Section 4.0, Introduction to the Analysis.
