Vista Verde Ranch Revised Draft Environmental Impact Report Vesting Tentative Tract & Oak Tree Permit Preliminary City Comments on RDEIR Poorly prepared, self-serving and lacks complete, critical analysis Provides conflicting/erroneous information and updated studies do not appear to adequately address concerns Dismisses certain issues as less than significant which may be significant and require additional mitigation Mitigation measures listed in summary are inconsistent with measures included in applicable impact analysis sections making it unclear which listing of measures are intended to apply

Vista Verde Ranch Revised Draft Environmental Impact Report Vesting Tentative Tract & Oak Tree Permit Preliminary City Comments on Project All outstanding issues related to connection of streets and/or sewers though or into the City should be fully addressed prior to further action on any development proposal. Any consideration of alternative designs needs to understand these self-created limitations and respect the unique environment and character of the entire 150 acres (not just the so-called project site); respect the impact to the historic and environmental character of the Tzu Chi property; and, respect the residential neighbors on all sides of the property (Via Verde, Valley Center and Mesa Oaks). Since this property is located in an adopted Sphere of Influence, any development should be processed through the City with the intent of annexation and any project should respect the City General Plan and zoning.
