IV - ENVIRONMENTAL CONSEQUENCES AND MITIGATION MEASURES This section contains an analysis of the impacts which can be expected upon the implementation of the preferred alternative. Where feasible or practical, measures have been identified for inclusion in the project which will mitigate the severity of the identified impacts. Section VII.0 of this document discusses the significance of any impacts identified which cannot be mitigated to insignificant le- v-e--I's-. Several technical studies have been prepared to provide the technical basis for this environmental document, and are hereby incorporated by reference. These specialized studies, which are listed below, are available from the City of Santa Ana Public Works Agency, 101 West Fourth Street, Santa Ana, California 92702. -- Traffic and Circulation Impact Analysis, Willdan Associates, May 1987 -- Historic Property Survey Report, Willdan Associates, May 1987 -- Draft Relocation Impact Study, Willdan Associates, February 1988 -- Air Quality and Noise Technical Studies, Endo Engineering, May 1987 -- Biological Assessment for Santiago Creek Channel, Dr. Richard Vogl, March 1987 -- Evaluation of Existing Bristol Street Bridge at Santiago Creek, Willdan Associates, December 1986 A.

In fact, probably all areas that will be disturbed during street construction activities have previously been disturbed. New landscaped berms, two to four feet in height, could be introduced into the proposed parkways along both sides of Bristol, constituting a different surface IV -1
