will be pursuant to the City's standard building permit approval process. The impacts or additional <br />mitigation over that which is included in the Final Fashion Square EIR is required. <br />Biota <br />The site is entirely developed and vegetation is comprised of introduced ornamental trees, <br />shrubs and grasses. Consistent with the Fashion Square EIR, there is no native vegetation. No <br />impacts will occur from the proposed expansion. <br />The City will require decorative landscaping as part of the final plan approval process. A <br />variance for landscaping that would allow for plant groupings and clusters, rather than the required <br />one planter for each 10 parking spaces is being considered. , <br />Archaeology <br />The Fashion Square EIR refers to a records search that was completed for that EIR. No sites <br />were recorded on the site. Because the site is entirely paved and developed, it is not anticipated that <br />archaeological sites are present under the areas of the proposed expansion modifications. No <br />impacts are expected. <br />Traffic and Circulation <br />Existing Roadway System <br />EremLus <br />The area is served directly by three freeways, the Santa Ana (1-5), the Garden Grove (SR-22) <br />and the Orange (SR-57), and indirectly by a fourth, the Costa Mesa (SR-55). The I-5 Freeway has <br />been undergoing major improvements over the last several years which has included widening of <br />the freeway mainline to add two additional lanes in each direction and high occupancy vehicle <br />(HOV) lanes, and accompanying improvements to the ramp system. In particular, improvements <br />to the 1-5 ramps at 17th Street, Buffalo Street and Santa Clara Avenue were completed in mid• 1995, <br />Ramp improvements, including HOV access ramps, are ongoing at Edgewood Road and <br />improvements to the I-5/SR-22 interchange were completed in late 1995. These improvements have <br />resulted in improved traffic flow along the 1.5 Freeway and between the I-5 and the Garden Grove <br />Freeways, particularly during peak traffic periods. However, some slowing continues to occur in <br />the vicinity of the I.5/SR-22 interchange on both the 1-5 Freeway and the SR-22 Freeway during <br />peak traffic hours. <br />Addendum ElRfor Main Place/Santa Ana (E)?96.033) April 4,1996 <br />Page 6 go Projece No. 96.066 <br />75D-396 <br />
