3. Environmental Checklist San Leandro Treatment Wetland IS/MND 3-63 February 2024 of Service (LOS) A or B during peak times.55,56 These standards are meant to regulate long-term traffic increases from new developments and are not applicable to temporary construction projects. Given this context, the construction traffic is expected to be noticeable but will not significantly deteriorate long-term traffic conditions on major routes like I-880 and Davis Street. The operation phase of the Project will maintain the existing traffic and circulation patterns with no significant increase in onsite personnel. Consequently, the Project is not anticipated to cause further exceedance of the level-of-service standards set by the Alameda CTC. Thus, the traffic impact during both the construction and operational phases of the Project is assessed as less than significant. Impact Designation: Less than Significant Impact b) Significantly increase vehicle miles traveled: As highlighted earlier, construction traffic linked to the Proposed Project is not expected to substantially affect long-term traffic flow on key routes such as I- 880 and SR-112 (the segment of Davis Street east of Doolittle Drive). During the operational phase of the Project, traffic and circulation patterns will largely remain consistent with current conditions. The continuation of maintenance trips will not lead to any significant increase in the number of onsite personnel. Consequently, in line with CEQA Guidelines §15064.3(b), the Proposed Project is not anticipated to increase vehicle miles traveled by automobiles. Therefore, the Project's impact on long- term operational traffic and circulation is considered to be less than significant. Impact Designation: Less than Significant Impact c) Increase transportation hazards: The construction and operations of the Project are not expected to modify the current layout of the road network in the area, nor will they introduce any unsafe design elements. Additionally, the Proposed Project will not bring in any uses that conflict with those already accommodated by the existing road system in the Project vicinity. As a result, the Proposed Project would have a less-than-significant traffic hazard impact. Impact Designation: Less than Significant Impact d) Result in inadequate emergency access: As previously mentioned, the construction and operation of the Proposed Project will not change the current layout of the existing road network serving the area. This includes maintaining unaltered access to local streets and adjacent properties, as well as ensuring uninterrupted access for emergency vehicles. Consequently, there will be no impact on emergency access due to the Project. Impact Designation: No Impact Cumulative Impacts on Transportation 55 Alameda County Transportation Commission. 2023.
