One significant off-site impact was identified in the existing condition; and one significant off-site impact was identified in the cumulative condition. The impact in the existing condition was related to construction activities, and the cumulative impact was related to intersection operations. Construction-related activities could create potential conflicts with other roadway users, such as construction-related activities resulting in lane closures along the project frontage, construction vehicles queueing within the public right-of-way waiting entry to the site, construction worker parking in non-designated parking areas, or construction debris on public streets. Construction impacts would be temporary in nature; however, this impact would require mitigation, as proposed in the 1998 HVSP FEIR MM B6. A construction management plan would enhance the intent of the original mitigation measures and would reduce the project’s potential for construction vehicle conflicts with other roadway users. Implementation of MM B6 and the construction management plan MMTrans-1 as a condition of approval for the proposed project would reduce the temporary construction impacts to less than significant. Although construction impacts would be temporary, development of a construction management plan would reduce the potential for construction vehicle conflicts with other roadway users. Because MM B6 is intended to mitigate conflicts between roadway users, the preparation of a construction management plan to further reduce potential conflicts between roadway users during construction, consistent with the intent of MM B6. Additionally, the proposed project would pay all applicable local and regional transportation impact fees to fund the construction of planned roadway improvements in the area. Therefore, with the addition of a condition of approval to enhance the intent of MM B6 as it applies to the Spotorno Project, the proposed project would not result in any peculiar effects and would not result in new or more severe impacts related to LOS standards and travel demand measures, or other standards for designated roads or highways beyond what was previously analyzed in the 1998 HVSP FEIR. b) Inconsistent with CEQA Guidelines Section 15064.3 Would the project: Would the project conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b)? This question was not included in the 1998 HVSP FEIR. No determination was made in the 1998 HVSP FEIR regarding the level of significance related to the HVSP’s consistency with CEQA Guidelines
